Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] like Figures 1 to 9 As shown, this utility model provides a disassembly device for a gear shaft of a motor, including a housing 100, a clamping mechanism 200 and a high-voltage output mechanism 300 mounted on the housing 100, and a motor 400 mounted on the clamping mechanism 200. The high-voltage output mechanism 300 has a sealing joint 340. The clamping mechanism 200 includes a clamping base 210 mounted on the housing 100, a sliding assembly 220 and a buffer assembly 230 mounted on the clamping base 210, and an adjusting seat 24 mounted on the sliding assembly 220. 0. A detachable support member 250 is mounted on the adjusting seat 240; a motor positioning plate 260 is mounted on the adjusting seat 240; and a detachable motor clamping plate 270 is mounted on the motor positioning plate 260. One end of the motor 400 is mounted on the motor clamping plate 270, and the other end of the motor 400 is placed on the support member 250. The motor 400 has a detachable gear shaft 410, and one end of the sealing joint 340 is mounted on the gear shaft 410. Multiple support members 250 are provided and spaced apart. High-pressure oil can be output through the high-pressure output mechanism 300. The output high-pressure oil enters the gear shaft 410 through the sealing joint 340. The impact force of the high-pressure oil pushes the gear shaft 410 outwards. The disassembly process is efficient and safe, avoiding damage to the motor, reducing production costs, and facilitating widespread adoption.
[0026] The buffer assembly 230 includes a first hydraulic buffer 231 and a second hydraulic buffer 232 mounted on the clamping base 210, and the adjusting base 240 is located between the first hydraulic buffer 231 and the second hydraulic buffer 232. The first hydraulic buffer 231 and the second hydraulic buffer 232 can buffer the adjusting base 240, reduce the impact force on the adjusting base 240, ensure the normal installation of the motor 400 and the disassembly of the gear shaft 410, and also ensure that the adjusting base 240 will not detach from the sliding assembly 220.
[0027] The sliding assembly 220 includes a first slide block 221 and a second slide block 222 mounted on the clamping base 210, a first slider 223 mounted on the first slide block 221, and a second slider 224 mounted on the second slide block 222. One end of the adjusting seat 240 is mounted on the first slider 223, and the other end of the adjusting seat 240 is mounted on the second slider 224. Multiple first sliders 223 and second sliders 224 are provided and spaced apart. The adjusting seat 240 is slidable, facilitating the installation of the motor 400 and the disassembly of the gear shaft 410.
[0028] It also includes multiple handles 280 installed on the adjusting seat 240, which are spaced apart. The handles 280 are used to pull the adjusting seat 240, which is equipped with the motor 400, toward the sealing joint 340 until the gear shaft 410 and the sealing joint 340 are tightly connected.
[0029] The motor positioning plate 260 is provided with a limiting strip 261, and the motor clamping plate 270 is provided with a limiting groove 271. Both the limiting strip 261 and the limiting groove 271 are U-shaped, and the limiting groove 271 is matched with the limiting strip 261. The setting of the limiting strip 261 and the limiting groove 271 allows the motor clamping plate 270 to be detachably installed on the motor positioning plate 260, which is simple and convenient to install and remove. When changing to a motor 400 of different sizes, the corresponding motor clamping plate 270 can be replaced, which has strong applicability.
[0030] The high-pressure output mechanism 300 includes a high-pressure oil pump 310, an oil pipe fixing plate 320, and an oil pipe 330 installed in the chassis 100. The clamping base 210 has a plurality of spaced reinforcing ribs 211. The oil pipe fixing plate 320 is fixedly connected to the reinforcing ribs 211. One end of the oil pipe 330 is installed in the high-pressure oil pump 310, and the other end of the oil pipe 330 is installed in the oil pipe fixing plate 320. The sealing joint 340 is installed in the oil pipe fixing plate 320 and communicates with the oil pipe through the oil pipe fixing plate 320. The high-pressure oil pump 310 can output high-pressure oil to the oil pipe 330, and then transport it through the oil pipe 330 to the oil pipe fixing plate 320. The oil pipe fixing plate 320 then continues to transport it to the sealing joint 340, and finally the sealing joint 340 transports it into the gear shaft 410. The gear shaft 410 impacts the motor 400 from inside, causing it to detach from the motor 400, thus completing the disassembly. The disassembly process is efficient and safe, avoids damage to the motor, reduces production costs, and is conducive to promotion.
[0031] The motor 400 is provided with a shaft groove 420, the gear shaft 410 is provided with a through groove 411, the sealing joint 340 has a first connecting end 341, one end of the gear shaft 410 is installed in the shaft groove 420, the through groove 411 communicates with the shaft groove 420, one end of the sealing joint 340 is installed in the through groove 411, the diameter of the through groove 411 is smaller than the diameter of the first connecting end 341, and the through groove 411 and the first connecting end 341 are interference fit. In this embodiment, the sealing joint 340 also has a second connecting end 342, which is securely mounted on the oil pipe fixing plate 320. The oil pipe fixing plate 320 has an oil connection groove inside, and the oil pipe 330 is connected to the second connecting end 342 through the oil connection groove. Since the through groove 411 and the first connecting end 341 are interference fit, the connection between the gear shaft 410 and the sealing joint 340 is extremely tight. The high-pressure oil output by the high-pressure oil pump 310 is transported to the oil pipe fixing plate 320 through the oil pipe 330, and then further transported to the sealing joint 340 through the oil pipe fixing plate 320. The oil is then transported to the through groove 411 by the sealing joint 340. After reaching one end of the through groove 411, it begins to impact the motor 400, thereby forming a counter-impact force on the gear shaft 410, which causes the gear shaft 410 to begin to detach from the motor 400 until disassembly is completed.
[0032] In this embodiment, the chassis 100 has a controller and a central control console. The central control console and the high-pressure oil pump 310 are both electrically connected to the controller. Commands are input to the controller through the central control console, and then transmitted to the high-pressure oil pump 310 through the controller to complete the control of the pump and control its switching. At the same time, the information of the high-pressure oil pump 310 is also transmitted to the controller and displayed through the central control console.
[0033] The working principle of this utility model is as follows: First, open the casing 100 to expose the clamping mechanism 200. Then, place the motor 400 with the gear shaft 410 to be disassembled on the support 250, and clamp the end of the motor 400 with the gear shaft 410 onto the motor clamping plate 270. Then, pull the adjusting seat 240 with the handle 280 to move it, which in turn drives the motor 400 to move towards the sealing joint 340 until the gear shaft 410 and the sealing joint 340 are tightly fitted. Then, close the casing 100 and start the high-pressure oil pump 310. The high-pressure oil output from the high-pressure oil pump 310 is transported to the oil pipe fixing plate 320 via the oil pipe 330, and then further transported to the sealing joint 340 via the oil pipe fixing plate 320. From there, it is transported to the through groove 411. Once it reaches one end of the through groove 411, it begins to impact the motor 400, thereby creating a counter-impact force on the gear shaft 410. This causes the gear shaft 410 to begin to detach from the motor 400 until disassembly is complete. The disassembly process is efficient and safe, avoids damage to the motor, reduces production costs, and is conducive to widespread adoption.
