Description

A column 20 is mounted through columns 18 and guides 19, kinematically connected with the drive 21 of its reciprocating movement in a vertical plane. A removable bar 22 is fastened to the ejector 20 with a series of grooves 23 (FIG. 2) under the rod parts 16 and latches 24.

The grooves 15 in the replaceable plate 14 of the gate 3 and the holes 23 in the replaceable plate 22 of the ejector are coaxially with each other and the holes of the base part 5 of the assembled product and together form a slot under the rod parts 16. The number of slots 15 and 23 and the pitch between them is equal to the number of holes in the part 5 and step between them.

To ensure the alignment of the grooves of the interchangeable strips 14 and 22 in the vertical plane, the fasteners 24 serve, and to ensure the coaxiality of the sockets for the core parts with the axes of the holes of the base parts 5 of the assembled products in the horizontal plane serve adjustable stops 12.

To communicate the gate 3 of the reciprocating movement is the drive (not shown in the drawings).

The actuator 4 serves to alternately communicate to the sliders 7 a reciprocating movement in the horizontal plane parallel to the carrier plane of the interchangeable strips 14 and 22.

The safety bar is installed above the removable slide 14 of the gate parallel to its carrying plane.

 25 are mounted on columns 18 of the discharger 20 and serve to return the latter from the lowest position to the highest one.

Assembled products consist of a base part 5 and core parts 16 (Fig. 5).

The device works as follows. When moving the gate 3 together with the ejector 20 to one of the extreme positions (for example, left, Fig. 2) the rod parts 16 supplied from the tray 11, under the action of its own weight sink into the grooves 15 and 23 of the interchangeable bars 14 and 22 of the gate 3 and the resetter 20, respectively, and moving in them parallel to themselves in a horizontal position. When the gate 3 reaches the left stop 12, the drive 21 is activated, under the action of which the resetter 20 together with the interchangeable bar 22 and columns 18 moves in a vertical plane in the guides 19 to the lowest position, as a result of which the left ends of the rod parts 16 exit from the grooves 23 the interchangeable bar 22 and the interchangeable bar 14 from the grooves 15 are prevented from falling out by the left safety bar 13 and the slide 7 (left) moving in the horizontal plane parallel to the carrier plane of the interchangeable bars 14 and 22 to the extreme right position, The base parts 5 of the assembled product are assembled from the left accumulator 6 and assemble (for example, press) the core parts 16 with the details 5. After that, moving in the opposite direction to the SRI to the extreme left position, the slider 7 removes the assembled products with the bar 10 (Fig 7) from the assembly area, i.e., it releases the right end of the rod-like parts 16 from the slots 15 of the interchangeable strip 14.

10 As soon as the right end of the rod parts 16 comes out of the grooves 15, the actuator 21 is turned off, and the ejector 20, moving to the uppermost position under the action of the springs 25, strikes with its upper surface along the lower part of the plane of the spring-loaded ejector 9 and moves up , removes collected items. As soon as the lower plane of the sub-spring of the valuable ejector 9 is freed from

0 resetter 20, ejector 9 occupies the lowest position, and in the opened slots of the sliders 7 as they approach the left drive 6 sinks in new parts 5. Gate 3 starts from the drive

5 move to the rightmost position (Fig. 3), and the rod parts 16 supplied from tray 11, again sink into the slots 15 and 23 of the interchangeable bars 14 and 22, moving in them parallel to themselves in a horizontal position. When approaching the right stop 11, the actuator 21 is triggered again, and the resetter 20 with the interchangeable bar 22, moving in the vertical plane, occupies the lowest position. As a result, the left ends of the core parts 16 are freed from the grooves 23 of the interchangeable strip 22 and are kept from falling out of the grooves 15 of the laughing bar 14 by the right safety bar 13, and

0 slider 7 (right), moving in the horizontal plane parallel to the carrier plane of the interchangeable strips 14 and 22 to the right extreme position, grabs the basic parts 5 from the second (right) drive 6.

5 and assembles the core parts 16 with them.

After that, the slider 7, moving to the extreme left position, removes the assembled products from the assembly zone, i.e., releases the right end of the core parts 16 from the grooves 15 of the interchangeable strip 14. As soon as the right end of the part 16 has left the groove 15, the drive 21 again, the diverter 20 is moved to the highest position

5 by the action of the springs 25, strikes the upper plane along the lower part of the spring-loaded ejector 9, which, moving upwards, removes the assembled products from the sockets. The right slider 7 occupies the leftmost, and the ejector 9 occupies the extreme

lower position, and in the vacant

sockets again sink new parts. Cycle

repeats.

The proposed device will allow to increase labor productivity in the operations of supplying and assembling rod-like parts with the assembled product by 3-4 times.
