[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] This embodiment is intended to help solve the problem that the mechanical gripper may separate the coupling from the output shaft of the motor, which may damage the coupling. Figure 1-5 A coupling disassembly tool comprises a disassembly barrel 1, on which a supporting device 2 is installed. The supporting device 2 is driven by a pneumatic device 3. After the pneumatic device supports a coupling body 8, the gas pressure is transmitted to a pushing device 5 through a transition device 4. The pushing device 5 resists a motor 9 to realize the disassembly between the motor 9 and the coupling body 8.

[0025] In this embodiment: the support device 2 includes a support shell 201 fixedly connected to the outer wall of the disassembly barrel 1, the support shell 201 is connected to the disassembly barrel 1, and a support rod 202 is slidably connected inside the support shell 201, and an arc-shaped support plate 203 is fixedly connected to one end of the support rod 202. Under the drive of the pneumatic device 3, the sliding of the support rod 202 is realized, and then the arc-shaped support plate 203 is driven to prop up and fix the coupling body 8, which can fix the coupling body 8 relative to the disassembly barrel 1, so as to facilitate the subsequent pushing of the motor 9 out of the coupling body 8.

[0026] In this embodiment: the pneumatic device 3 includes a No. 1 piston plate 301, which is slidably connected in the disassembly barrel 1, and a pneumatic push rod 302 is fixedly connected to one side of the No. 1 piston plate 301. The pneumatic push rod 302 pushes the No. 1 piston plate 301 to slide in the disassembly barrel 1 and compresses the air pressure in the disassembly barrel 1, providing power for the support of the support device 2. At the same time, under the push of the pneumatic push rod 302, the output shaft of the motor 9 can be pushed out of the coupling body 8 through the pushing device 5, which is the power source for the movement of the entire device.

[0027] In the present embodiment: the transition device 4 includes a No. 1 connecting ring 401 fixedly connected to the inner wall of the disassembly barrel 1, and a No. 1 one-way valve 402 is fixedly connected to the No. 1 connecting ring 401. The No. 1 one-way valve 402 is installed with a pressure relief device 7. Through the setting of the No. 1 one-way valve, the disassembly barrel 1 can be divided into a first space 403 and a second space 404. This division can ensure that after the supporting device 2 completely supports and fixes the coupling body 8, the output shaft of the motor 9 is pushed to prevent the situation where it cannot be disassembled.

[0028] In this embodiment: No. 1 one-way valve 402 includes No. 1 ventilation pipe 4021 fixedly connected to No. 1 connecting ring 401, and No. 1 sealing plate 4022 is provided on one side of No. 1 ventilation pipe 4021, and No. 1 sealing plate 4022 is connected to No. 1 connecting ring 401 through No. 1 spring 4023. When the pneumatic push rod 302 pushes No. 1 piston plate 301, the gas is compressed, so that the gas pressure in No. 1 ventilation pipe 4021 increases, and No. 1 sealing plate 4022 moves outward due to the action of the gas pressure, overcoming the resistance of No. 1 spring 4023, opening No. 1 ventilation pipe 4021, and allowing gas to flow into the first space 403.

[0029] In this embodiment: the pushing device 5 includes a No. 2 piston plate 501, which is slidably connected in the disassembly barrel 1. The No. 2 piston plate 501 is connected to the push plate 503 through a connecting rod 502. The connecting rod 502 penetrates the disassembly barrel 1. When the pneumatic push rod 302 pushes the gas from the second space 404 to the first space 403, the No. 2 piston plate 501 slides in the disassembly barrel 1 and drives the push plate 503 to resist the output shaft of the motor 9 through the connecting rod 502, thereby pushing the output shaft of the motor 9 out of the coupling body 8, thereby realizing the separation of the coupling body 8 and the motor 9.

[0030] In this embodiment: the pushing device 5 is reset by the resetting device 6 after the disassembly is completed. The resetting device 6 includes a No. 2 connecting ring 601. The No. 2 connecting ring 601 is elastically connected to the No. 2 piston plate 501 through a No. 3 spring 602. After the disassembly is completed, the pneumatic push rod 302 drives the No. 1 piston plate 301 to reset. At this time, the No. 2 piston plate 501 is reset by the action of the No. 3 spring 602. The elastic force ensures the rapid and stable reset of the pushing device 5, which helps to maintain the stability of the system between each operation cycle and improves the reliability of the entire tooling system.

[0031] In this embodiment: the pressure relief device 7 includes a No. 2 ventilation pipe 701 fixedly connected to the No. 1 sealing plate 4022, and a No. 2 sealing plate 702 is arranged on one side of the No. 2 ventilation pipe 701. The No. 2 sealing plate 702 is connected to the No. 2 ventilation pipe 701 through a No. 2 spring 703. Under the action of the No. 3 spring 602, the air pressure in the first hole is compressed, and then the No. 2 sealing plate 702 is driven to pull up the No. 2 spring 703, so that the two spaces divided by the No. 1 one-way valve 402 are connected, and the excess gas in the first space 403 is driven into the second space 404 through the pressure relief device 7, and then the gas inside the second space 404 can be completely restored to the initial state, so that the No. 1 piston plate 301 can completely return to the initial position.

[0032] Working principle: insert the disassembly barrel 1 into the hole of the coupling body 8, and control the pneumatic push rod 302 to push the No. 1 piston plate 301 to slide in the disassembly barrel 1, drive the No. 1 piston plate 301 to compress the air pressure in the disassembly barrel 1, and then drive the support rod 202 in the support shell 201 connected to the disassembly barrel 1 to slide, so that the arc-shaped support plate 203 props up the disassembly barrel 1, and then fix the disassembly barrel 1 relative to the pneumatic device 3. After that, the pneumatic push rod 302 continues to push the No. 1 piston plate 301, and at this time drives the No. 1 sealing plate 4022 to pull up the No. 1 spring 4023, and then the No. 2 piston plate 501 can be driven by the pneumatic push rod 302 to slide in the disassembly barrel 1, so that the push plate 503 contacts the output shaft of the motor 9, and by continuously applying pressure, the motor 9 is separated from the coupling body 8, and the disassembly of the coupling body 8 is realized.

[0033] After the disassembly is completed, the pneumatic push rod 302 drives the No. 1 piston plate 301 to reset, and the No. 2 piston plate 501 is reset by the action of the No. 3 spring 602, compressing the air pressure in the disassembly barrel 1, and then driving the No. 2 sealing plate 702 to pull up the No. 2 spring 703, so that the two spaces divided by the No. 1 check valve 402 are connected, and the excess gas in the first space 403 is driven to enter the second space 404 through the pressure relief device 7, and then the gas inside the second space 404 can be completely restored to the initial state, so that the No. 1 piston plate 301 can be completely returned to the initial position. It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a process, method, article or device.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
