Description

one

The invention relates to the field of welding, in particular to .me.haniz.mm supply welding machines.

A known rack-and-pinion device containing mounted on ocnoBaiuiH peiiK) with the possibility of returning and displacing movement, the shaft can be rotated around its axis in one direction, connected with the shaft shaft and the gear link through which the shaft is kinematically connected with the rail.

In the known reciprocating mechanism, the chopper movement of the rail fixed to the pilind rod is transformed into a rotary shaft.

The proposed rack-and-pinion device is pre-lateral, advantageously for sub-parts during welding.

In order to regulate the stroke of the rail, which serves as a drive for supplying parts using the stops placed around the disk circumference with the possibility of changing the distance between them, the device is equipped with a clamp bushing mounted on the shaft with the possibility of non-displacement along the shaft, with the outer side of the disc and performed with a collet of a protrusion of a mum kope n with fingers m, interacting with lugs, on the other end, the rail is made with wedge mbs, interacting with

annular vysm.m bushings. The disk carrying the Zpora is mounted ia the base motionless.

The drawing shows the proposed device.

The device contains a rail /, rigidly connected with a brush 2 clips 3. P placed on the fixed disk 10. On the shaft 6 there is a toothed link // made in the form of an overhead coupling securing the rotary shaft 6 in one positioned 1I. The clutch is fixed to the gear rack, interacting with the rail. Sleeve 5 but the unidirectional device for the sliding disk Ub spring J2. To the rail / mount the carriage podachp parts (pa drawing ne not shown).

The device works in the following way.

The retraction of the shaft 2 with the rail I, in conjunction with the carriage, upwards the shaft 6c with the sleeve J is turned clockwise. As soon as the finger S of the sleeve 5 reaches the stop 9, the carriage stops, and a command to reverse is given from the limit switch. When rail 1 is returned, the clutch does not work, i.e., shaft 6 does not revolve. At the end of the course of the rail / wedge

4 pushes 7 bushings on ring

5 and moves it along the shaft 6, the finger 8 out of contact with the stop 9. With the next working stroke simultaneously with the clan protrusion 4, the shaft 6 moves 5, and at the initial moment the sleeve 5 is in the depressed state n the finger 5 rotates relative to the unor 9. Passing the stop 9, the finger 8 with the sleeve 5 is moved by the spring 12 to the left to its original position, at this moment the vystun 4 comes out of the contact pin

with the protrusion 7. Reaching the next unor 9, the finger 8 stops and the process repeats. The process is programmed by changing the distance between the lugs 9 by extending or removing the lugs.

Subject invention

A gear-rack unit, primarily for supplying parts during welding, contains mounted on the base with the possibility of reciprocating non-displacement, the shaft can be rotated around its axis in one direction, a disk coaxially aligned with the shaft and a gear link through which the shaft is kinematically connected rail, characterized in that, in order to regulate the rail stroke, which serves as a drive for feeding parts when using stops placed on the disk circumference with the possibility of changing the distance between them, the device packed with a cylindrical sleeve mounted on the shaft with the possibility of non-displacement along the shaft, spring-loaded relative to the disk and made with an annular protrusion at one end n with a finger cooperating with the stops, on the other side of the box, a vane protrusion interacting with the annular protrusion of the sleeve, and the disk is fixed.
