Description

Technical Field

[0001] The utility model relates to the technical field of clamping equipment, in particular to a simple and rapid internal expansion type clamping device for a motor stator. Background Technique

[0002] In the field of motor production, when clamping and moving a motor stator, generally, the method of manually grasping is adopted to clamp and move the motor stator, resulting in low production efficiency and high labor intensity of workers, which is not suitable for large-scale industrial production.

[0003] Therefore, people have designed a clamping device to clamp the motor stator. By using the frictional force of the first support claw and the second support claw to lift the motor stator, the first support claw and the second support claw are inserted into the through hole of the motor stator, and the lifting rod is lifted upward. The first connecting rod and the second connecting rod move towards the middle due to their weights, so that the top ends of the first bending rod and the second bending rod move towards the middle. Since the first bending rod and the second bending rod are folding rods bent inward, their bottom ends expand outward, and the connecting rod ensures that the first bending rods and the second bending rods on both sides move synchronously; the first bending rod and the second bending rod will cause the first support claw and the second support claw to move away from each other. Under the limiting action of the two follower rods, the two support claws move outward in parallel; the first support claw and the second support claw use frictional force to grab the motor stator, and the motor stator can be quickly clamped and lifted.

[0004] In the above-mentioned prior art, although the motor stator can be clamped and lifted, and then the clamping device is driven to move by other equipment, thereby driving the motor stator to move, during the moving process, the bottom of the motor stator is not supported. If the support claws are not clamped in place, it is easy to cause the motor stator to fall and be damaged during the moving process, and it cannot support the motor stator well during the moving process, which cannot meet the needs of people. Therefore, we need a simple and rapid internal expansion type clamping device for a motor stator. Content of the Utility Model

[0025] Through the above technical solution, when the stator body 4 is clamped and lifted, the reduction motor 202 works to move the two moving blocks 204, driving the electric telescopic rods 206 to move, so that the two support plates 207 move to the bottom of the stator body 4. Through the work of the electric telescopic rods 206, the support plates 207 move upward to support the stator body 4, preventing the stator body 4 from falling and being damaged during the movement, strengthening the stability and meeting the needs of people; By controlling the intake and exhaust of compressed air, the lifting and resetting of the clamping block 311 are controlled.

By the resetting of multiple clamping blocks 311, the stator body 4 can be quickly put down. The structure is simple and convenient to use.

[0026] Specifically, the mounting base 1 and the positive and negative threaded rod 203 form a rotating structure through the reduction motor 202, and one end of the reduction motor 202 extends into the mounting base 1 to be connected to the positive and negative threaded rod 203.

[0027] Through the above technical solution, the connection effect between the mounting base 1, the reduction motor 202 and the positive and negative threaded rod 203 is strengthened. When the reduction motor 202 works, it can drive the positive and negative threaded rod 203 to rotate well. A bearing is arranged at one end of the positive and negative threaded rod 203, and the positive and negative threaded rod 203 rotates more stably relying on the bearing.

[0028] Specifically, the inner wall shape and size of the installation groove 201 match the outer wall shape and size of the moving block 204, and the inner wall of the installation groove 201 fits against the outer wall of the moving block 204.

[0029] Through the above technical solution, the connection effect between the installation groove 201 and the moving block 204 is strengthened, and when the moving block 204 moves, it moves more stably within the installation groove 201.

[0032] Specifically, the number of sliding grooves 308 is multiple, and the multiple sliding grooves 308 are equidistantly formed in the fixed seat 301.

[0033] Through the above technical solution, by providing multiple sliding grooves 308, it is convenient for each sliding groove 308 to be connected to each piston 309.

[0034] Specifically, the fixed seat 301 and the piston 309 form a sliding structure through the sliding groove 308, and the outer wall of the piston 309 fits against the inner wall of the sliding groove 308.

[0035] Through the above technical solution, the connection effect between the fixed seat 301, the sliding groove 308 and the piston 309 is strengthened, enabling the piston 309 to move well within the sliding groove 308. A sealing ring is provided on the piston 309.

[0036] Specifically, one end of the piston rod 310 passes through the sealing seat 312 and is connected to the clamping block 311.

[0037] Through the above technical solution, a sealing ring is provided inside the sealing seat 312, and one end of the piston rod 310 passes through the sealing ring, strengthening the sealing performance; a sealing ring is also provided at the installation connection between the sealing seat 312 and the fixed seat 301 to strengthen the sealing performance; one end of the first intake pipe 302 and the second intake pipe 305 is connected to the air source, and electromagnetic valves are connected to one end of the first intake pipe 302, the first outlet pipe 304, the second intake pipe 305 and the second outlet pipe 307 outside. This device is powered by an external power supply and controlled by an external controller.

[0038] In use, when first clamping the stator body 4, the fixing seat 301 extends into the stator body 4. The first intake pipe 302 and the second outlet pipe 307 are opened through the solenoid valve, and the first outlet pipe 304 and the second intake pipe 305 are closed through the solenoid valve. Compressed air enters the first channel 303 through the first intake pipe 302. The gas enters the plurality of chutes 308 from the first channel 303. The gas pushes the piston 309 to move, the piston 309 drives the plug rod 310 to move, and the plug rod 310 drives the clamping block 311 to press against the inner wall of the stator body 4. By pressing against the inner wall of the stator body 4 with the plurality of clamping blocks 311, it can be clamped quickly. After clamping, it is grasped and lifted, and the stator body 4 leaves the platform and is held in the air. By operating the reduction motor 202, the forward and reverse threaded rod 203 is driven to rotate, so that the two moving blocks 204 move more stably in the installation groove 201. The moving block 204 drives the electric telescopic rod 206 to move, and the electric telescopic rod 206 drives the support plate 207 to move. The two support plates 207 move to the bottom of the stator body 4. By operating the electric telescopic rod 206, the support plate 207 moves upward to support the stator body 4, preventing the stator body 4 from falling and being damaged during the movement; when it is necessary to release the clamping of the stator body 4, by operating the reduction motor 202, the two support plates 207 are moved away from the bottom of the stator body 4. By closing the first intake pipe 302 and the second outlet pipe 307 and opening the second intake pipe 305 and the first outlet pipe 304, compressed air enters the second channel 306 from the second intake pipe 305, pushing the piston 309 to move, resetting the piston 309, and the clamping block 311 no longer presses against and clamps the stator body 4, thereby releasing the clamping of the stator body 4. The structure is simple and convenient to use, and all the work is completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
