Aiming at the above-mentioned problems in the prior art, the utility model provides a new pin shaft disassembly and assembly tool, which not only has low manufacturing cost, but also has high safety and reliability, simple structure, easy operation, and saves time and effort.

In order to achieve the above object, the technical solution adopted by the utility model is:

A tool for disassembling and assembling pin shafts, characterized in that it includes lug plates, eyebolts, segmented brackets and crowbars;

There is a positioning hole on the lug plate that can be set on the pin shaft, and a threaded hole that is threadedly connected with the segmented bracket is provided beside the positioning hole;

The segmented support includes two parallel support plates and a plurality of blocking rods arranged in parallel between the two support plates, and the distance between each adjacent blocking rod can accommodate crowbars to pass through;

The eye screw has a collar that accepts a crowbar through it.

The front end of the segmented bracket has a threaded cylindrical head, which is threadedly connected with the threaded hole on the ear plate through the cylindrical head.

A threaded hole is provided on the end face of the pin shaft.

The front end of the lifting ring screw is a threaded rod, and the rear end is the collar, and the lifting ring screw is threaded through the threaded rod at the front end and the threaded hole on the end face of the bearing pin, so that the lifting ring screw is fixed on the bearing pin.

The beneficial effects of the utility model are:

The pin shaft dismounting tooling of the utility model has a simple structure, reduces manufacturing costs, is easy to carry, easy to operate, saves time and effort, and improves operational flexibility and safety.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Fig. 1 and Fig. 2: the utility model comprises ear plate 1, ring screw 3, segmented support 4 and crowbar 5.

The segmented support 4 includes two parallel support plates 42 and a plurality of retaining rods 43 arranged in parallel between the two support plates 42, and the distance between each adjacent retaining rods can accommodate the passage of the crowbar 5; The front end of the segment bracket 4 has a threaded cylinder head 41 .

A set of positioning holes on the pin shaft 2 is arranged on the ear plate 1, and a threaded hole is arranged next to the positioning holes.

The segmented bracket 4 can be threadedly connected with the threaded hole on the ear plate 1 through the cylindrical head 41 at its front end, so that the segmented bracket 4 is vertically fixed on the ear plate.

Drill a threaded hole 21 on the end face of pin shaft 2 .

The front end of the lifting ring screw 3 is a threaded rod, and the rear end is a collar 31 that can accommodate the crowbar 5 to pass through. on pin 2.

Combined with Figure 3, the process of removing the pin shaft 2 is as follows:

Set the positioning hole on the ear plate 1 on the pin shaft 2, and the segmented bracket 4 is threadedly connected with the threaded hole on the ear plate 1 through the cylindrical head 41 at the front end, so that the segmented bracket 4 is fixed on the ear plate 1; The eyebolt 3 is fixed on the pin shaft 2 through threaded connection. One end of the crowbar 5 penetrates into the collar 31 of the eye screw 3 through the gap of the blocking rod on the segmented bracket 4, and the other end of the crowbar 5 exerts a force (thrust) toward the ear plate 1, and through leverage, Pry the pin shaft 2 to move outward. In order to ensure the effect of the force, pull out the crowbar 5 every time a section of the pin shaft 2 is pried out, and then pass through the gap of the next bar farther away from the ear plate 1, and continue to pry the pin shaft 2 until the pin shaft 2 is fully levered out.

With reference to Figure 4, the process of installing pin shaft 2 is as follows:

Set the positioning hole on the ear plate 1 on the pin shaft 2, and the segmented bracket 4 is threadedly connected with the threaded hole 11 on the ear plate 1 through the cylindrical head 41 at the front end, so that the segmented bracket 4 is fixed on the ear plate 1 ; The eyebolt 3 is fixed on the pin shaft 2 through a threaded connection. One end of the crowbar 5 penetrates into the ring 31 of the eye screw 3 through the gap of the blocking rod on the segmented bracket 4, and the other end of the crowbar 5 exerts a force (pull force) away from the ear plate 1, and through leverage, Pry the pin shaft 2 to move inward. In order to ensure the effect of force, every time a section of the pin shaft 2 is pressed, the crowbar 5 is pulled out, and then passes through the gap of the next stop bar close to the lug plate 1, and continues to press the pin shaft 2 until the pin is pressed all the way in.
