Technical Field

[0001] The utility model relates to the technical field of railway locomotive equipment, and particularly to a disassembly tool for locomotive copper discs. Background Art

[0002] The copper disc is a key component located at both ends of the axle. Its main function is to fasten the axle end part, prevent external substances such as dust and moisture from invading key parts such as bearings, so as to ensure the safety and stability of the locomotive. During locomotive maintenance and repair, the copper disc needs to be frequently disassembled and replaced.

[0003] In the prior art, a puller tool is usually used. One end of it is connected and fixed to the locomotive copper disc, and then manual pulling force is applied at the other end to pull out the locomotive copper disc from the end of the axle. However, the self-weight of the locomotive copper disc itself is relatively large. This manual way of pulling out the locomotive copper disc usually requires multiple operators to pull out the locomotive copper disc, which easily leads to the problem of low disassembly efficiency. Moreover, the locomotive copper disc may fall during the pulling out process, which is likely to cause harm to the operators.

[0004] That is to say, the existing method of manually pulling out the locomotive copper disc has the problems of low disassembly efficiency and harm to the operators. Summary of the Utility Model

[0027] In one embodiment, the first rotating mechanism includes:

Detailed implementation manners

[0046] The present utility model will be further described below in conjunction with the accompanying drawings.

[0047] As Figures 1 to 3 shown, the present utility model provides a locomotive copper disc disassembly tool, which includes a clamping mechanism 10 and a disassembly mechanism 20. The clamping mechanism 10 is fixed on the robot arm; the disassembly mechanism 20 is arranged on the clamping mechanism 10; the disassembly mechanism 20 includes two long screws, and the two long screws are arranged in one-to-one correspondence with two threaded holes of the locomotive copper disc 100. The long screws can extend into the corresponding threaded holes and rotate to fix the locomotive copper disc 100. The long screws are pressed down to take out the locomotive copper disc 100 from the end of the axle, and the clamping mechanism 10 can clamp the taken-out locomotive copper disc 100.

[0048] In the above setting, the robot arm can move the whole locomotive copper disc disassembly tool to the end of the axle and align the two long screws with the two threaded holes of the locomotive copper disc 100 one by one. Since the locomotive copper disc disassembly tool is fixed by the robot arm, the two long screws inside it rotate in the corresponding threads to fixedly connect the locomotive copper disc 100. In this way, pressing down the long screws can disassemble the locomotive copper disc 100. Thus, the quick disassembly of the locomotive copper disc 100 by the locomotive copper disc disassembly tool is realized. Furthermore, the disassembly efficiency is improved. Moreover, the clamping mechanism 10 can clamp the taken-out locomotive copper disc 100. This can prevent the locomotive copper disc 100 from falling during the disassembly process, thereby reducing the risk of on-site operation and further ensuring the safety of the operators.

[0049] Specifically, as Figures 1 to 3As shown, in one embodiment, the clamping mechanism 10 includes a support plate 11, a stop block 12, a first clamping component 13, and a second clamping component 14.

The first clamping component 13 and the second clamping component 14 can simultaneously apply a thrust to the outer peripheral surface of the locomotive copper disc 100 to press the locomotive copper disc 100 against the stop block 12.

[0050] Specifically, as Figures 1 to 3 shown, in one embodiment, the support plate 11 is an equilateral triangle plate, and the stop block 12, the first clamping component 13, and the second clamping component 14 are respectively disposed at three included angle positions of the equilateral triangle plate.

[0051] It should be noted that the three corners of the equilateral triangle plate in this application are chamfered, which facilitates the installation of the stop block 12, the first clamping component 13, and the second clamping component 14. At the same time, it can also prevent it from hurting on-site assembly personnel.

[0052] Specifically, as Figures 1 to 3 shown, in one embodiment, the central axes of the stop block 12, the first clamping component 13, and the second clamping component 14 are arranged at an included angle of 120° with respect to the central axis of the locomotive copper disc 100.

[0053] Of course, according to the actual situation, the support plate 11 can also be a circular plate or a square plate.

[0054] In an alternative embodiment not shown in the drawings of this application, the clamping mechanism 10 includes a support plate 11, a stop block 12, and a first clamping component 13.

That is, the first long screw 233 and the second long screw 241 are coaxial with two threaded holes of the locomotive copper disc 100 respectively.

[0061] Specifically, as Figures 1 to 3As shown, in one embodiment, the first rotating mechanism 23 includes a servo motor 231, a speed reducer 232, and a first long screw 233. Among them, for the servo motor 231, its fixed end is slidably connected to the support frame 21; for the speed reducer 232, its input end is connected to the drive shaft of the servo motor 231; for the first long screw 233, it is connected to the output end of the speed reducer 232.

[0062] Specifically, as Figures 1 to 3 shown, in one embodiment, the first rotating mechanism 23 has the same structure as the second rotating mechanism 24. In this way, the first rotating mechanism 23 and the second rotating mechanism 24 can be interchanged, thereby improving the convenience of subsequent replacement and maintenance of the locomotive copper disc disassembly tool.

[0063] Specifically, as Figures 1 to 3 shown, in one embodiment, the disassembly mechanism 20 further includes a first feed cylinder 25 and a second feed cylinder 26. Among them, for the first feed cylinder 25, its fixed end is fixed on the support frame 21; for the second feed cylinder 26, its fixed end is fixed on the support frame 21; the drive end of the first feed cylinder 25 is connected to the first rotating mechanism 23 and is used to drive the first rotating mechanism 23 to slide along the first direction, and the drive end of the second feed cylinder 26 is connected to the second rotating mechanism 24 and is used to drive the second rotating mechanism 24 to slide along the first direction.

[0064] Specifically, as Figures 1 to 3 shown, in one embodiment, the disassembly mechanism 20 further includes a first guiding structure 27 and a second guiding structure 28. Among them, for the first guiding structure 27, it is arranged on the support frame 21 and the first rotating mechanism 23 and is used to guide the first rotating mechanism 23 to slide along the first direction; for the second guiding structure 28, it is arranged on the support frame 21 and the second rotating mechanism 24 and is used to guide the second rotating mechanism 24 to slide along the first direction.

[0065] Specifically, as Figures 1 to 3 shown, in one embodiment, the first guiding structure 27 and the second guiding structure 28 have the same structure. In this way, the first guiding structure 27 and the second guiding structure 28 can be interchanged, thereby improving the convenience of subsequent replacement and maintenance of the locomotive copper disc disassembly tool.

[0066] Specifically, as Figures 1 to 3 shown, in one embodiment, the first guiding structure 27 includes a guiding shaft 271, which is arranged on the support frame 21 and is slidably connected to the housing of the speed reducer 232 in the first rotating mechanism 23 along the first direction. A spring 272 is sleeved on the guiding shaft 271, which is located between the housing and the support frame 21 and has a buffering effect.

[0067] It should be noted that the above-mentioned tool adopts components such as a servo motor, a reducer, a long screw, a feeding cylinder, a tightening cylinder, a tightening block, a guiding shaft, a spring, and a quick-change disk, and is connected to the manipulator through the quick-change disk. When working, the manipulator drives the disassembly tool to move to the front of the end face of the locomotive copper disk (referred to as the copper disk). The feeding cylinder acts to push the servo tightening assembly (servo motor + reducer + long screw) towards the copper disk, and the long screw is inserted into the threaded hole on the copper disk. Then the servo motor works, and the torque is transmitted to the long screw through the reducer, so that the long screw is screwed into the threaded hole of the copper disk. Pressing down the long screw can push the copper disk off the locomotive shaft end. Then the two tightening cylinders act to make the tightening block in close contact with the copper disk, so that the copper disk is fixed to the disassembly tool through friction. Finally, the copper disk is disassembled from the shaft center through the action of the industrial manipulator.

[0068] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
