Wherein, the driving mechanism 4 is a linear motion, which can be an electric cylinder, an air cylinder, an oil cylinder, or a hydraulic cylinder, preferably a hydraulic cylinder.

Among them, the pulling claw mechanism 2 is used to hook the disassembled part 200, and the driving mechanism 4 is used to withstand the fixed part 100. When the fixed part 100 is resisted, the pulling claw mechanism 2 hooks the disassembled part 200, and the driving mechanism 4 When working, the piston rod protrudes, causing the disassembled part 200 to produce a relative displacement relative to the fixed part 100, so that the disassembled part 200 is disassembled.

In this embodiment, the problem that the claw mechanism 2 is easily deformed and loosened during the pulling process can be avoided through the anti-slip device 3 arranged on the periphery of the claw mechanism 2 .

Wherein, the claw mechanism 2 may include a plurality of pull rods 22 , one end of the plurality of pull rods 22 is connected to the support 1 , and the other end is used to hook the part 200 to be disassembled.

And the push rod 33 of the anti-off device 3 passes through the frame body 31 and is in vertical contact with the pull rod 22 of the claw mechanism 2. During the pulling process, the push rod 33 is pressed against the pull rod 22, thereby preventing the pull rod 22 from loosening outwards. take off.

The position of the anti-off device 3 can be freely selected. Before the work, the anti-off device 3 is placed on the periphery of the pull bar 22, preferably on the hook of the pull bar 22, so as to achieve the best stress effect.

As a further preference of this embodiment, the support 1 is provided with an adjustment groove 23 for adjusting the opening distance of the pull rod 22, the adjustment groove 23 is preferably radially arranged, the number of the adjustment groove 23 is consistent with the number of the pull rod 22, and the number of the pull rod 22 One end is engaged in the adjustment slot 23 , and the other end is used to hook the part 200 to be disassembled.

Through this preferred mode, the pull rod 22 can move freely in the adjustment groove 23, and the opening range of the pull rod 22 can be adjusted conveniently, satisfying the disassembly of different parts sizes.

Of course, the claw mechanism 2 can also adopt the following structure:

Referring to FIGS. 4-6 , it includes a plurality of pull rods 22 and an adjustment frame 21 connected to the fixed part of the driving mechanism 4 .

The pull rod 22 can move freely in the adjustment groove 23, and the opening range of the pull rod 22 can be adjusted conveniently, so as to satisfy disassembly of different parts sizes.

As shown in FIG. 5 , a baffle 24 may be provided on the end of the pull rod, so that the pull rod 22 is engaged in the adjustment slot 23 .

As a further preference of this embodiment, the anti-off device 3 may also include an adjustment plate 32 and a guide groove 34 provided in the frame body 31, the adjustment plate 32 is engaged in the guide groove 34, and the adjustment plate 32 is provided with a top for installing The threaded hole of push rod 33.

Wherein the adjustment plate 32 is that the length can be selected in various specifications, as shown in Figure 7, when selecting a larger adjustment plate 32 for use, the position of the adjustment plate 32 will move down, because the guide groove 34 has a taper, the more downward The bigger it is, so when a larger adjustment plate 32 is used, the adjustment plate is forced to move down, which can be applied to the disassembly of smaller parts, and the push rod 33 no longer passes through the frame body 31, but directly passes through The adjustment plate 32, because the guide groove 34 is tapered, when the push rod 33 is against the pull rod 22, a reaction force will be generated on the adjustment plate 32, causing the adjustment plate 32 to be in close contact with the guide groove 34, thereby realizing the anti-off. Conversely, if a smaller adjusting plate 32 is selected for use, larger parts can be disassembled.

Wherein, one end of the driving mechanism 4 is connected to the support 1 , and the other end is used to contact the fixed part 100 , preferably the fixed part is connected to the support 1 , and the movable part is connected to the fixed connection 100 .

Wherein, in order to facilitate the movement of the dismounting device, a roller 11 is provided at the bottom of the support 1 .

As a further preference of this embodiment, the part removal device may further include a jacking mechanism 5 for supporting the part 200 to be removed.

Wherein, the jacking mechanism 5 includes a lifting mechanism 51 and a support block 52 located on the lifting mechanism 51. The lifting mechanism 51 is used to realize up and down lifting, which can be an oil cylinder, a jack, an air cylinder or an electric cylinder, and the support block 52 is used to support the Part 200 may be a V-shaped block or an arc block.

Through this preferred method, the part 200 to be disassembled is prevented from falling during disassembly, and plays a very good supporting role.

It can be seen that the utility model can be used to dismantle couplings, flanges, bearings or other sets of parts with tight shaft holes, because the structure is provided with an anti-off device 3, which can prevent the claw mechanism 2 from easily deforming. loosening problem;
