The inventive device has a stepped axle to accommodate parts that require disassembly and Assembly and planted with a gap on the axis, a Cup connected to the skeleton by means of the guide finger mounted on an axle springs, locking removable parts in the initial position and creates a resistance force removal of the securing these parts to the axis washers and nuts, creating limited access to capture the cylinders, the inner ring and the base sheet associated with the frame and control sensors, mounted in a groove axis and the tabs that secure the removable parts in a fixed position, contact sensors are connected in a common circuit and displayed on the remote control. 4 Il. The invention relates to training and can be used as a simulator to develop professional skills for Assembly and disassembly of the parts connected with tension, with the stripper.In Fig. 1, 2 shows the construction of the simulator of Fig. 3 - sensor simulator of Fig. 4 - electric is based on spring 3, acting on the axle 4 having a longitudinal groove in which is inserted a finger 5, which is the directing and limiting the axial displacement of the axis 4. On the axis planted 6 disc with holes on the periphery of the disk 7 with a spherical surface and the disk 8 between which are spacer spring 9, which is loaded through the washer 10 nut 11.The cylinder 12 and the inner ring 13 is welded to the frame corners. The support sheet 15 is attached to the frame by bolts. In axis 4 are the sensors 16 for remote monitoring. The sensor consists of a stationary contact 17, the insulator 18, the role of the movable contact does remove the item 19. Electric diagram of the simulator is made of single-line (Fig. 4). To the stationary contact 17 through the drilling in the axis passes a conductor included in a common circuit and displayed on the remote control.The device operates as follows.The teacher sets the part number be compacted, for example under the number 7. The learner through the table of symbols determines that the number 7 is the drive with a spherical surface located in the cylinder, creating a limited access to capture. Visually determine the distance to the details, access to vypolnennaya or disassembly of parts, United with tightness, choose the type and layout of the puller, providing for its construction operations disassembly or Assembly of the parts connected with tension. Collects puller.If done correctly the layout captures the details at number 7 on the periphery of the grippers, power screw rests on axis 4 (Fig. 1) and carries out the removal of parts, overcoming the resistance of the springs. The contacts will open, and the remote teacher goes out pilot light.When correctly selected the layout extractor to capture details impossible.Estimated parameter that determines the degree of fitness of the student, is the time required to select the layout extractor, Assembly, engagement shoot details and creation efforts, sufficient for its removal.
