Description

one

The invention relates to the assembly industry and can be applied to the assembly of links of agricultural machines of agricultural machines.

On the main auth .. sv. No. 653019 is known a semiautomatic device for assembling links of caterpillars, which comprises a finger pressing unit mounted on the basis of the working member; made in the form of two parallel beams rigidly interconnected, installed with the possibility of reciprocating movement, in one of which a pusher is mounted, and in the other with a centering pusher rod mounted with the possibility of axial movement and evenings located on both sides of the crossbar burta. Between the traverses there is a mechanism for the step-by-step feeding of the links, a node for feeding the fingers and a support for the node for feeding the fingers 1, placed with the possibility of reciprocating movement on the traverse.

The base of the working body is equipped with a fixed limiter of the oriented pair of links installed between the movable cross-beams of the press-fitting unit, with a gap

100-150 mm above the surface of the links required for their movement by the step feed mechanism during the assembly of the track web.

The disadvantage of this semiautomatic device is that there is no clear fixation of the oriented pair of links in the process of their assembly due to the presence of a gap between the immobile limiters and the pair of links collected, which creates conditions for their distortions from the approach of the finger at the time of its pressing, disrupting the process assembly. At the same time 5 skew can not prevent and

centering rod, the rigidity of which is limited to its transverse cross section. limited, in turn, by the diameter of the lugs of the assembled links. This reduces the reliability and performance of the machine.

The purpose of the invention is to increase the reliability and performance of a semi-automatic machine for assembling links of tracks

5 due to the precise fixing of the orientation of the bathroom pair of links in the process of their assembly.

This goal is achieved by

which is a semi-automatic machine for link assembly

0 tracks supplied mounted on

the base under the spring Fie with other clamps for the links of the tracks, a slider installed between the cross-pieces in the guide bases with the possibility of reciprocating movement and fixed with wedges in contact with the clamps.

FIG. 1 shows a semi-automatic cross-section; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one.

The semi-automatic machine for assembling the links of the tracks contains the crossbars 2 and 3 mounted on the base 1 with the possibility of reciprocating movement, rigidly connected to each other. In the traverse 2, the pusher 4 is mounted, connected to the power cylinder 5, and in the traverse 3, the centering rod 6 is mounted coaxially to the pusher 6. spring-loaded clamps 7 with roller supports 8 at the ends are mounted on the base. Under the springs 7 in the direction of the gazii base are placed with the possibility of reciprocating movement. Sliders 9 with wedge lugs 10, having horizontal sections with notches. The supporting surface of the clamps 7 is equipped with elastic pads 11.

Semiautomatic works as follows.

In the process of assembling, the centering rod b orients the eyelets of the lugs of the assembled pair of links 12 and at the end of the orientation operation of the yoke 3 moves the sliders 9 by moving them in the guide holes of the base 4, thus freeing the roller bearings 8 from the impact of wedges 10 Spring-loaded The m 7 is lowered in the guide holes of the base 1 until the elastic pads 11 come into contact with the surface of the oriented centering rod b of the pair of links 12 fixed to the surface. the process of assembling them in this position, ensuring at the same time due to its elasticity

some of their mobility within the preservation of coaxiality of the lugs of a pair of links and excluding the engagement of the centering rod.

At the time of completion of the assembly process, a pair of links 12 of the yoke 2, when approaching its extreme position, moves the sliders 9, which, by acting with their wedge lugs 10 on the roller supports 8, press the spring loaded pin 7 to the upper position, thereby freeing up the assembled links groove. In this case, the roller bearings 8 move along the horizontal section of the wedge supports 10 up to the west side to the recesses, thereby

5 are fixed in this position. Semiautomatic prepared for the assembly of the next pair of links.

Equipment of the semi-automatic clamps automatically triggered

0 during reciprocating traverse synchronously with the orientation of the holes of the lugs of the assembled pair of links and their assembly, virtually eliminates the incoherence of the links due to their skewing during the assembly process, which increases the productivity of the semiautomatic device by 10-15%.
