(5) DEVICE FOR ASSEMBLING DETAIL TYPE TYPE SHAFT

one

The invention relates to the automation of assembly processes and can be used in machines and automatic shafts inserts, for example, in body parts, plates, plates j, etc.

A device is known for assembling parts such as a shaft hub, comprising a base, an actuator, a feeder, a shaft position limiter and a push-to-pin lj.

A disadvantage of the known device is that it requires additional elements and a node-feeders, intermediate converters, a control system that matches all movements.

The purpose of the invention is to eliminate these drawbacks, as well as improve the quality of the assembly by eliminating various kinds of damage to the surfaces of the mating parts.

To do this, the device is equipped with a column and a pin on its end, as well as a spring-loaded slider, a rod and a lever hinged to the slider, the slider being mounted on the fifth, and the spring-loaded pushing slider with the possibility of interaction with the rod located on. n those parallel to the pusher. In addition, the shaft position limiter is made in the form of an elastic bracket mounted on the seal.

FIG. 1 shows an aggregate head, a general view; FIG. 2 type A in FIG. one; in fig. 3 is a view B in FIG. 2; in fig. 4 and 5 are variants of possible assembly of parts by means of this modular head.

A device for assembling parts 1 and 2 contains a pusher 3, ykpleplenny on the rod k, which combines to move in the hole of the boss 5, which is part of the slider 6. The latter is movably installed in the groove of the guide pin 7, which is fixed on the spring-loaded column 8. Bottom the slider 6 is bounded by plates S, fastened on point 7. In slider 6 on the axis 10 there is a movable lever 11, on which a pin 12 bearing the plate spring 13 is fixed. In the upper part, the lever 11 ends with the plate I. The latter is in contact with the rod 15 installed feat in the tide 16 (which is part of the belt 7) and spring-loaded spring 17. The end of the rod 15 rests on the end surface of the base part 2. A finger 18 is fastened on the rod, and a pin 19 on the rod 5, which are connected by a spring 20 pusher 3 with rod k in the lower position. On the pusher 3 is made comb 21 with a beveled lower end. The slider 6 with the boss 5 is pushed through the pin 22 to the right by a spring 23, one end of which is fixed to the column 8. By means of several spring bent rods 2, a restrictive bracket 25 is attached. The latter restricts the position of the shaft 1 on the surface of the part 2 so that the front end of the shaft 1 was above the hole 2b in the part 2. The lever 11 and the finger 12 are held in the upper position by the spring 27 and are installed with the possibility of moving its axis 10 in the groove 28. For supplying the parts to the assembly position the unit is equipped with a holoska batch 29 (Fig. Device for assembly according to the modification shown in Fig., contains a collet 30 for fixing the shaft 1 and part supplied to the assembly bushing 31. Modifying the device for the assembly shown in Fig. 5 containing tray 29 for supplying the parts 31 from below under shaft 1 and additionally swivel socket 32. The device is completely independent and is mounted on a power unit, on a pneumatic or hydraulic actuator rod. Such devices on a single drive can be mounted several and all of them can work either independently or together spot. The device works as follows. The aggregate head is lowered to the working position, where the shaft is fed over the surface of the base part 2 (this may be the case, plate, cover, plate, strip, etc.). In this case, the pusher 3 with its lower end presses on the left end of the shaft 1. The latter begins to rotate and is located above the opening 2b so that its left end begins to enter (initially with some distortion) into the opening 2b of the part 2. During this rotation of the reaction of shaft 1 on Knob 3 causes the latter to shift to the left. When parts are fed along the tray to the working position, the process of reversing and inserting the part and shaft 1 into the hole of part 2 is carried out by the pusher 3, which descends downwards due to the force exerted on the shaft 1 by the actuator head and also by the force from its lever. Tray 29 is configured to lower somewhat. Therefore, the supplied parts and others approach the end of part 2, but they cannot move further and do not interfere with insertion of shaft 1 into the hole of part 2 until the end of the assembly. This greatly simplifies the assembly process, since the assembled part 2 is at the same time a cutter of parts when each of them arrives at the working position. Thus, the pusher 3, together with the rod k and the slider 6, are displaced to the left, stretching the spring 23. At the same time, the comb 21 of the pusher 3 pushes the brace 25 to the left. During the movement of the column B with point 7 downward, the bracket 25 rests against the end face of the part 2. At the same time (as the column 8 moves downwards) the spring rods 24 are deformed, which allows pushing the shaft 1 into the hole 2b to the required depth. Together with the downstroke of the column 8 from point 7, the rod 15 rests against the end of the part 2, which, having overcome the force of the spring 17, with its upper end presses the plate of the lever 11. Therefore, the lever 11 rotates. At the same time, the finger 12 with the plate-oh 13 pushes (rakes) the shaft 1 with the force and helps it to turn into a vertical position. The shaft 1j turns, finally coming into contact with the plane of the slide 6, which presses down the shaft 1, forcing it to enter the hole 2b of the part 2. Since the shaft 1 also rotates, this rotation causes the pusher to move to the left. rod 4; the contact point of the pusher 3 with the shaft is displaced along its shaft. Therefore, the slider 6 moves to the left and the slider 6 moves to the left, the slider 6 tons does not have the upper end of the shaft 1 to the left, i.e. It makes it become vertical, which speeds up assembly. Together with the movement of the slider 6, the axis 10 of the lever P. also moves. Therefore, the latter not only rotates, but also moves progressively, which accelerates the process of giving the shaft 1 a vertical position and under the action of the vertical force the shaft 1 enters the hole 2b of part 2. At this assembly is completed.
