(57) Abstract:

Usage: technological transport for teams and manufacturing lines, mainly for the processing of products with a vertical axis location. The inventive process the transport containing the bearing parts having the ability to move in the guide, the actuator, the latch, the actuator is placed in rails inside technological transport and made in the form of the drive carriage and the auxiliary carriage. And inside the drive carriage posted by mobile leash, with the possibility of transverse displacement with respect to traffic and engagement by its end, made in the form of a fork with a link, the other end of which is made in the form of lugs, covering a rolling pin, mounted on the auxiliary carriage. The latch is made in the form of a spring relative to the slide support and the wedge firmly attached to the slide connected with the power cylinder, and bearing and wedge placed in the enclosure, with the possibility to adjust the position along the guide rails, which are mounted on racks, with a basic expansion elements for positions and actuators. The links are connected midna to technological transport for Assembly and processing lines, mainly for processed products with a vertical axis location (type shock absorber, gas stops and so on ), and can be used for equipping process specified products.

The purpose of the invention is the reduction of size and metal consumption and improve the reliability of transport.

In Fig. 1 shows the transport, General view; Fig. 2 - section a-a in Fig. 1; Fig. 3 - section b-B in Fig. 2; Fig. 4 - view In Fig. 2; Fig. 5 - view of G in Fig. 3.

The transport contains guides 1 I-beam section, closed by a plate 2, in the final part of turning into radial surface 3 of the corresponding profile. Between the rails 1 and bar 2 is placed shelves 4 bearing 5 links of the chain of transport, which are interconnected with the axis 6 through the spherical bearing 7 in a closed horizontally disposed circuit of the load-bearing links.

In addition, the support link contains the inner side of the horizontal rollers 8 and limiting the upper roller 9, and the fingers 10, 11. Inside the transport on the inner side of the I-beam rails 1 is the drive of the transport.

The actuator consists of two carriages, one of which is the drive carriage 12 moves in the direction of EET able to move perpendicular to the direction of transport by means of auxiliary cylinder 16.

A drive carriage 12 posted by gripping the plug 17, one end of which passes through a window in the wall of the I-beam rail transport and has a groove 18 for engagement of the finger 10 of the link and the other end is made in the form of lugs 19 and covers the roller 20, is equal to the length of stroke of transport and mounted on the auxiliary carriage 15.

At the site, where more precision is required inside the transport on the inner side of the I-beam rail with a corresponding window in the wall set the latch (Fig. 5), which consists of a accommodated in the housing 21 with the bores of the movable support 22 and the wedge 23 in the form of a truncated rolling pin. Moreover, the bearing is spring-loaded by a spring 24 against the slider 25, which is connected with the piston rod 26 and the wedge 23.

Both ends of the transport end radial rotary part 27, and one of them with a tensioning device 28 is spring-loaded. I-beam rails installed in the rack 29 with the surface 30, the connecting grooves 31 and holes 32 to link with transitional elements 33, nodes 34 and the slide 35. In the walls of the guides I made the window 36.

Technological transport works as follows.

In the original Polozheniye vtyanuta the rod of the drive cylinder 14. The circuit carrier transport links recorded during extended cylinder rod 26 of the retainer. Upon receipt of the appropriate signal from the control circuit by a line bearing retainer 22 and the wedge 23 is disposed through the cylinder 26 to its original position, after which the main drive cylinder 14 moves through the capture plug 17 chain bearing parts of the stroke.

After that, the locking device locks the chain bearing parts as follows. When the slider 25 from the cylinder 26 of the actuator latch first freely under the action of the spring 24 is inserted into the fastening area under the finger 10 bearing 22. Then in the further course of the wedge 23 on the slide 25, acting on the finger 11, brings a level 5 transport, but rather with the whole chain of links to a fixed position, pressing it to the support 22. Gripping the plug 17 is withdrawn from engagement with the finger bearing element 5 with the support carriage 15. The main drive cylinder 14 returns the carriage 12 with a grapple fork 17 to its original position, and the end of the plug, made in the form of lugs 19, slides over the rolling pin 20 mounted on the auxiliary carriage 15.

After completion of the stroke of the main drive cylinder to its original position auxiliary cared who leads it into engagement with the finger 10 of a bearing element. The transport is ready for the next cycle. (56) USSR Author's certificate N 1405978/27, class B 23 K 37/04, 1986.
