Embodiment 1

[0041] see Figure 1 ~ Figure 3 As shown, the present invention provides a combined puller, the middle part of the first connecting piece 11 is provided with an internally threaded hole 113, and the screw rod passes through the internally threaded hole 113 to connect with the first connecting piece 11 threaded connection, rotating the first connecting piece 11 can adjust the position of the first connecting piece 11 on the screw 10; the plurality of first beams 12 are detachably connected to the first connecting piece 11;

[0042] Each of the first beams 12 is detachably connected with a first sliding block 19 or a claw 13 , and the first sliding block 19 is connected with a pin pull screw 18 .

[0043] There is a detachable structure between the first beam 12 and the first connector 11, and the number of the first beam 12 is not limited. The number of the first beams can be adjusted according to the required pulling force to disperse the pull. Pulling force, to avoid the probl...

Embodiment 2

[0062] see figure 1 As shown, this embodiment provides a combined puller used as an external puller to realize the function of pulling out parts connected to the outside of the shaft, such as bearing parts, gear parts, bushing parts and the like.

[0063] The combined puller includes a first connecting piece 11, a screw 10, three first beams 12 and three jaws 13, the first connecting piece 11 is sleeved on the screw 10 and connected to the screw 10 Threaded connection, the plurality of first beams 12 are detachably connected to the first connecting member 11 respectively; the three claws 13 correspond to the three first beams 12 one by one and are detachably connected.

[0064] The first connecting piece 11 is in the shape of an annular sleeve, and an internally threaded hole 113 is provided inside the first connecting piece 11, and the screw rod 10 is threadedly connected with the first connecting piece 11 through the internally threaded hole 113, The first connecting member...

Embodiment 3

[0074] see figure 2 As shown, this embodiment provides a combined puller used as an inner puller to realize the function of pulling out parts connected inside the hole, such as bearing parts, oil seal parts and the like.

[0075] The combined inner puller includes most of the technical features as in Embodiment 1, the difference being:

[0076] The combined puller also includes a limiting disk 15, which has a second threaded hole 151, and the second threaded part 103 of the screw rod 10 is connected with the second threaded hole of the limiting disk 15. 151 connections.

[0077] The operation method is as follows: when using the combined puller to pull the parts inside the hole, first determine the relative position of the part to be pulled and the hole, and pass the second threaded part 103 of the screw rod 10 through the part to be pulled On the other side of the part, a limit plate 15 is set, the limit plate 15 is installed on the second threaded part 103 of the screw 10...

Abstract

The invention provides a combined puller for overcoming the problems of pulling jaw damage and single function in an existing puller. The combined puller comprises a first connection element, a screw rod and a plurality of first cross beams, wherein an inner thread hole is arranged in the middle of the first connection element, the screw rod penetrates through the inner thread hole so as to be in threaded connection with the first connection element, and the plurality of first cross beams are detachably connected with the first connection element respectively; and a first slide block or a clamping jaw is detachably connected to each of the first cross beams, and a pull pin screw is connected to each first slide block. The puller provided by the invention is simple in structure, easy to maintain, reliable in detachment effect, high in detachment efficiency, adaptive to different shapes needing pulling equipment, and capable of realizing many functions of inward pulling, outward pulling, pin taking and the like, thus achieving better adaptability, improving the performance thereof and increasing the efficiency thereof.

Description

technical field [0001] The invention belongs to the technical field of disassembling and assembling tools for industrial equipment, and in particular relates to a combined puller. Background technique [0002] With the development of science and technology, the volume of industrial equipment is getting bigger and bigger, and the assembly precision is getting higher and higher. A large-scale equipment often needs to be assembled with a large number of parts, and the complexity of the equipment is getting higher and higher. When a part of the equipment is damaged, limited by the equipment space and installation location, it is sometimes necessary to perform cumbersome disassembly to complete the replacement of equipment parts. This problem is particularly prominent in multi-axis joint robot equipment. The existing puller has a single structure and solidification, and it is difficult to adjust it in time, which affects work efficiency and application range. [0003] The existi...
