The feed mechanism and including centering links 4 caterpillars contains an inclined roller drive 13 and made in the form of fixing holes 14 to the flange of the 4 links in rails 3 with a step corresponding to the step chains 4 to interact with the latter.

For under what the actual content of the conveyor in a horizontal position mounted lower conveyor 15. To hold the parts against possible distortions in the horizontal plane during the pressing of the fingers 5 is mounted the upper conveyor 16. Roller conveyors 15 and 16 are mounted on one-way bearings 17 and 18.

The feeder fingers 5 includes a conveyor 19 with the tabs 20 and cells 21, driven by the cross-ploskorelefnoj transmission 22 through the pulleys 23 and 24 of the shafts 25 and 26 from the guide wheel 11. Feeding fingers 5 is provided with an inclined tray 27, and a fixing before feeding onto the conveyor 19 is carried out by means of the cutter 28, made in the form of plates 29, in the middle of the sides pivotally mounted on the supporting surface 30 in a horizontal plane in the direction of travel of the conveyor 19 move the fingers 5, forming duplici lever, the free end 31 which is spring-loaded from below by a spring 32 with the opportunity to interact with the protrusions 20 of the conveyor 19 move the fingers 5 and the other end 33 is made to an l-shape with the opportunity to interact with the 5 fingers on the inclined tray 27, and the horizontal axis 34 and 35 hinges 36 and 37 in the vertical plane is further provided with retaining levers 38 and 39 are rigidly coupled to the plate 29 with the possibility of interaction of the latter with the fingers 5 on the inclined tray 27.

For feed fingers 5 by means of the conveyor 19 of the cutter 28 to start pressing is provided by guide 42 mounted on the support 43.

The mechanism for pressing the fingers 5 is equipped with a rotary conveyor 44 is driven from the driving station through the shaft 9 and the drive sprocket /Fig. not shown/, similar to the drive wheel 10, which ensures synchronous movement mechanism pressing the fingers 5 with the feed mechanism and the alignment of the links 4, a steering wheel 45 mounted on the shaft 46, the pushers 47 containing a movable spring-loaded lugs 48 with restrictors 49, the rollers 50 on the one hand and the thrust part 51 is made larger than the diameter of the head of the finger 5 on the other hand, the thrust plate 52 mounted on the supports 53 and 54. In order to avoid abrupt actuation spring stop 48 of the pusher 47 at the time of exit from contact with the thrust plate 52, the upper outside area 55 last executed inclined in a horizontal plane away from the rotary conveyor 44, and the lower outside section 56 of the thrust plate 52 in the vertical plane angled from the vertical in the direction from the rotary conveyor 44. To exclude unforeseen situations during operation, and to implement preventive measures during maintenance of the device has a clutch 57 for nctioning end of the shaft 9 between the rotary conveyor 44 and the conveyor to move parts of 4 chains. For feeding the assembled track chain 1 at the winding provided by the guides 58.

Device for assembling the circuit operates as follows.

Filled with 5 fingers inclined chute 27. Turns on the idler pulley and rotates the conveyor 19. When this protrusion 20 presses on the free end 31 of the plate 29 duplicera lever cutter 28, compressing the spring 32, and cranks duplici arm hinges 36 and 37. While holding the levers 38 and 39, rising, release held the finger 5, which, rolling down on an inclined chute 27, the free end 31 of the plate 29, rests on the ledge 20 and enters the cell 21 of the conveyor 19. At the same time the other end 33 of the plate 29 duplicera lever cutter 28, rising, locks the next finger 5 on the inclined tray 27. As soon as the lug 20 will be released from contact with the free end 31 of the plate 29, the latter under the action of the spring 32 returns to its original position. While holding the levers 38 and 39 and l-shaped end 33 of the plate 29 are lowered, freeing the movement down the inclined chute 27 the rest of the fingers 5, which moves down, rest against the retaining levers 38 and 39. Then the cycle repeats. The 5 fingers trapped in the cells 21 of the conveyor 19, further movement along the guide 42. The distance between the axes of the cells 21 on the conveyor 19 is a center of RAS is the being between 5 fingers tracked circuit 1. When the first finger 5 on the disengagement of the conveyor 19 the idler pulley off.

Links 4 caterpillars are mounted on the conveyor and are centered crests in the fixing holes 14 of the guides 3 to line the beginning of the actuation of the first plunger 47. Turns on the drive station. This conveyor for moving links 4, the rotary conveyor 44 for pressing the fingers 5 and the conveyor 19 to supply 5 fingers start to rotate synchronously with equal linear speeds. The pushers 47, alternately rolling rollers 50 from the beginning of the surface of the bearing plate 52, resistant parts 51 abuts the head of the fingers 5 and moving as the movement of the conveyor without disturbing the alignment of 5 fingers, pressed them in the eyes of the links of the track chain. The lower roller 15 and the upper conveyor 16 are rigid guides to collect the circuit and eliminate skewed to the horizontal plane. For a more secure fit chain guide step between the rollers of the roller conveyers 15 and 16 selected lower step of the links of the track chain, excluding the simultaneous coincidence of the locations of the hinge joints of the links 4 with intervals between the rollers of the roller conveyers 15 and 16. With the passage at the bottom of the pusher 47, when the finger 5 has moved the entire width of the track chain 1, the plunger 47 is released and the contact with the head of the finger 5, and collected by the crawler chain 1 is moved along the guide rails 58 on the spool. For a smooth transition pushers 47 in the axial direction from the working position outside and avoid sharp trigger spring stop 48 of the pusher 47 at the time of exit from contact with the thrust plate 52 of the upper working section 55 of the latter from the completion of the pressing cycle is made inclined in a horizontal plane away from the rotary conveyor 44, and the lower outside section 56 of the thrust plate 52 in the vertical plane angled from the vertical in the direction from the rotary conveyor 44. Further, the pressing cycle is repeated continuously in motion. In the case of termination of work, you must leave on the inclined tray 27 the right amount of fingers 5, and an inclined roller conveyor-drive 13 the desired number of links 4, the other to remove. With the passage of the last link of the site pressing the idler pulley off.

A necessary condition for the smooth operation of the device is the same linear speed of the conveyor to move parts 4, a rotary conveyor 44 for pressing the fingers 5 and conveyor 19 for feeding fingers 5.

The hard part 51 of the pusher 47 is selected larger diameter head finger 5 to maximize the likelihood of reliable transmission of axial force C is pressed against the pusher 47 finger 5 if possible increase clearances from friction in the mating parts during long-term operation of the rotary conveyor 44 and conveyor to move parts of 4 chains and therefore, a possible slight misalignment of the axes of the plungers 47 and the axes of the fingers 5 mating with the lugs of the links 4.

Because the 4 links of the chain going through injected 5 fingers in motion as the movement of the conveyor, in the preparatory and initial period of pressing oriented, but not paired fingers through 5 links 4 are supported in a horizontal plane on the upper branch of the conveyor to move parts 4. To maintain the conveyor, and hence the links collected crawler chain in a horizontal position below the upper branch of the conveyor is mounted the lower conveyor 15. In the process of pressing the fingers 5 eyes of 4 links can be vertical components from horizontal forces pressing, due to errors based and the error in the shapes of the openings of the lugs within tolerances. To hold the parts against possible distortions in the horizontal plane during the pressing of the fingers 5 collected from the top branch of the chain is mounted the upper conveyor 16. The upper roller 16 and the lower roller 15 along the length should not be less than the length of the collected branch circuit to ensure reliable Assembly moving the chains on the entire area of the pressing finger 5 in the horizontal plane.

Thrust plate 52 is mounted slave is whose surface plane, perpendicular to the plane of the fitting to hold and transfer a significant axial force pushers 47 during the pressing of the fingers 5.

The base of the fingers 5 before pressing is ensured by fixing the latter in the cells 21 of the conveyor 19 during movement along the guide 42 to match the axis of the finger 5 and the plunger 47. At the time of interaction of the head of the finger 5 with persistent part 51 of the pusher 47 cell 21 of the conveyor 19 releases the finger 5. This conveyor for moving links 4, the rotary conveyor 44 for pressing the fingers 5 and the conveyor 19 to supply 5 fingers move with the same linear velocity. The deviation of the axis of the finger 5 from the axis of the holes of the lugs of the link 4 is possible only within the tolerance to perform the locking holes 14 in the elements of the conveyor to move parts 4 and compensate for the taper chamfer, which is available at the end of the finger 5.

Remote control /not shown/ power unit 6 drive station fitted with direct swing and reverse swing to prevent possible malfunction of the device when abnormal situations, such as when it enters the zone of the pressing substandard fingers 5 or 4 links having deviations in the dimensions of the lugs on the wheels. At the same time, to loosen the chain in the axial direction of the plunger 47, the finger 5, the lugs of the links 4, results in the Naya station stops and turns on the reverse stroke for convergence resistant parts 51 pushers 47 heads of the fingers 5 and subsequent restoration of normal operation of the device.

The cutter 28 provides automatic piece feeding fingers 5 in cell 21 of the moving conveyor 19 with simultaneous pressing of the basic array of fingers 5 on the inclined tray 27.

The use of cross-ploskorelefnoj transmission 22, allowing substantial coverage of the strap working surface of the pulleys 24 and 25, minimizes possible slippage of the belt relative to the pulleys due to low resistance to movement by moving the fingers 5 in cells 21 along the guide 42 to line fitting, which ensures reliable operation of the feed mechanism 5 fingers.

Thus, the proposed device for assembling circuit provides the Assembly of the crawler tracks by long pressing the fingers in the eyes of links in continuous motion conveyor, expanding technological capabilities and improving the reliability of the device and Assembly.
