[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 This utility model provides a technical solution: an assembly tool for a motor shaft that can be synchronously pressed at both ends, including a T-shaped seat 1 for support, a clamping mechanism 2 for limiting and a pressing mechanism 3 for pressing are provided inside the T-shaped seat 1, and a heating mechanism 4 for heating is provided above the T-shaped seat 1.
[0025] The heating mechanism 4 includes a horizontal plate 401 welded to the upper surface of the T-shaped seat 1. The bottom of the horizontal plate 401 is bolted to a guide rail b402 for guiding and an electric rail b403 for driving. The guide rail b402 and the electric rail b403 are bolted to a lifting plate 404 for hoisting. A cylinder 405 for lifting is connected through the lifting plate 404. The cylinder 405 passes through and slides within the horizontal plate 401, and the output end of the cylinder 405 is bolted to an electromagnetic induction heater 406 for heating.
[0026] The motor shaft, which can be synchronously clamped at both ends, is assembled with a fixture. The cable of the electromagnetic induction heater 406 is placed in the cable chain to prevent the cable from getting tangled. Starting the electric slide rail b403 can drive the lifting plate 404 to slide along the guide slide rail b402 to both sides, thereby driving the electromagnetic induction heater 406 to move. The electromagnetic induction heater 406 consists of a square shell and a coil. Electronic components such as capacitors and field-effect transistors are installed inside the square shell.
[0027] When heating of the motor shaft is required, one set of pneumatic fingers a204 clamps one end of the motor base, and another set of pneumatic fingers a204 and pneumatic fingers b304 move to both ends of the T-shaped seat 1. Then, the electric slide rail b403 is activated to bring the electromagnetic induction heater 406 close to the end of the motor base. Then, the cylinder 405 is activated to extend and move the electromagnetic induction heater 406 downward. The electric slide rail b403 is activated again to drive the electromagnetic induction heater 406 to fit onto the motor shaft and heat the motor shaft. When the electromagnetic induction heater 406 is close to the pneumatic fingers a204, another set of pneumatic fingers b304 clamps onto the motor shaft, and the original pneumatic fingers a204 are released from the motor shaft and moved to the end of the T-shaped seat 1, so that the electromagnetic induction heater 406 passes completely over the motor shaft. Then, the pneumatic fingers a204 are clamped onto the motor shaft again, so that the electromagnetic induction heater 406 can heat any part of the motor shaft.
[0028] When heating of the sheath is required, use the pneumatic finger b304 to clamp the sheath, start the electric slide rail b403 to move the electromagnetic induction heater 406 to the end of the sheath, and start the cylinder 405 to extend, aligning the electromagnetic induction heater 406 with the sheath. Start the electric slide rail b403 again to put the electromagnetic induction heater 406 on the sheath, thereby heating the sheath.
[0029] exist Figure 1 and Figure 2 In the middle, the clamping mechanism 3 includes a guide groove 301 opened in the T-shaped seat 1. A hydraulic rod 302 for driving is connected to the inner wall of the groove 301 by a bracket. The output end of the hydraulic rod 302 is connected to a support plate 303 by bolts. A guide slide rail a306 for guiding is connected to the T-shaped seat 1 near the bottom of the support plate 303 by bolts. The slide of the guide slide rail a306 is connected to the bottom of the support plate 303 by bolts.
[0030] The motor shaft, which can be synchronously pressed at both ends, uses an assembly fixture. The guide rail a306 guides the upright plate 303, allowing the upright plate 303 to slide to both sides. When the hydraulic rod 302 is activated to extend or retract, it drives the upright plate 303 and the pneumatic finger b304 to slide to both sides.
[0031] exist Figure 4 In the middle, a pneumatic finger b304 for clamping is bolted to one side of the upright plate 303, and a clamping plate b305 for abutment is bolted to the clamping finger of the pneumatic finger b304.
[0032] The motor shaft assembly fixture that can be synchronously clamped at both ends has its pneumatic finger b304 pipe placed inside the cable chain to prevent the pipe from getting tangled. The clamping plate b305 has a concentric arc groove that clamps the sheath while blocking the end of the sheath to prevent it from sliding off the clamping plate b305 when it is pressed onto the motor shaft.
[0033] When the protective sleeve is fitted onto the motor shaft, the hydraulic rod 302 is extended, and the pneumatic fingers b304 are moved to both ends of the T-shaped seat 1. The protective sleeve is placed into the clamping plate b305, and the pneumatic fingers b304 are activated to clamp the protective sleeve. Then, the motor shaft is placed into the clamping plate a205 and held by the two sets of pneumatic fingers a204. Then, the hydraulic rod 302 is shortened to pull the pneumatic fingers b304 closer to the pneumatic fingers a204, pressing the protective sleeve tightly onto the motor shaft.
[0034] exist Figures 1-3 In the case, the clamping mechanism 2 includes a guide groove 201 opened in the T-shaped seat 1, a support plate 202 for support is slidably connected in the groove 201, and an electric slide rail a203 for driving is bolted to the back of the T-shaped seat 1, and the slide of the electric slide rail a203 is bolted to the support plate 202.
[0035] The motor shaft assembly fixture, which can be synchronously pressed at both ends, drives the support plate 202 to slide to both sides in the slide groove 201 by starting the electric slide rail a203, thereby driving the pneumatic fingers a204 to move to both sides. The two sets of pneumatic fingers a204 operate independently, and the pipeline of the pneumatic fingers a204 is placed in the drag chain to prevent the pipeline from getting tangled.
[0036] exist Figure 4 In the middle, a pneumatic finger a204 for clamping is bolted to one side of the support plate 202, and a clamping plate a205 for abutting is bolted to the clamping finger of the pneumatic finger a204.
[0037] The motor shaft, which can be synchronously clamped at both ends, uses an assembly fixture. By activating the pneumatic finger a204, the clamping plates a205 move closer or further apart, thereby clamping the motor shaft.
[0038] While one set of pneumatic fingers a204 clamps the motor shaft, another set of pneumatic fingers a204 is removed from the motor shaft, allowing the electromagnetic induction heater 406 to pass over the motor shaft to heat it. When the electromagnetic induction heater 406 has passed halfway over the motor shaft, the other set of pneumatic fingers a204 clamps onto the motor shaft, and the original pneumatic fingers a204 are released from the motor shaft and removed, allowing the electromagnetic induction heater 406 to move away from the motor shaft.
[0039] In summary: When using this type of assembly fixture for motor shafts that can be synchronously clamped at both ends, first, place the motor shaft to be assembled in the clamping plates a205 on the two sets of pneumatic fingers a204. Activate the pneumatic fingers a204 to clamp the motor shaft. Then, release one set of pneumatic fingers a204 to release the motor shaft, and activate the electric slide rail a203 to adjust the position of the pneumatic fingers a204 to clamp the motor shaft again. Similarly, adjust the position of the other set of pneumatic fingers a204, record the clamping position, and ensure that both sets of pneumatic fingers a204 remain at the recorded position during the next clamping operation. Then, clamp the sheath onto... The device is clamped in the clamping plate b305, then a set of pneumatic fingers a204 are released and moved away from the motor shaft, allowing the electromagnetic induction heater 406 to be sleeved on the motor shaft for heating. Then, the pneumatic fingers a204 are re-clamped in the recording position, and the pneumatic fingers a204 that were originally clamped are released from the motor shaft and moved away. The electromagnetic induction heater 406 is removed from the motor shaft, and the pneumatic fingers a204 are re-clamped in the recording position. Then, the two sets of hydraulic rods 302 are shortened, and the two sets of sheaths are synchronously pressed against both ends of the motor shaft. The contents not described in detail in this instruction are prior art known to those skilled in the art.
