Description

Technical Field

[0001] This utility model relates to the field of motor housing clamping technology, specifically a motor housing clamping device. Background Technology

[0002] The motor housing is an important component of the motor. It plays multiple roles, including protecting internal components, providing mechanical support, heat dissipation, and dust and water protection. The motor housing can effectively prevent dust, moisture, and other external factors from damaging the internal components of the motor, ensuring the normal operation of the motor. The motor housing clamping device is a device used to securely and stably fix the motor housing to facilitate operation during assembly, maintenance, or testing.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219819486U) discloses a motor housing clamping device, including a support assembly. A support platform is mounted on top of the support assembly, and a clamping assembly is located inside the support platform. A fixing post is fixedly connected to the center of the bottom end of the support platform, and a worm gear is mounted on the outer side of the fixing post. A worm is located to the right of the worm gear and below the right side of the support platform. This utility model fits the housing onto three clamping jaws. The worm gear controls the rotation of the worm gear, and the arc-shaped groove inside the worm gear compresses the fixing post, causing the connecting block to move smoothly with the clamping jaws under the action of the limiting block. By controlling the three clamping jaws to move synchronously and move away from each other, the motor housing can be securely clamped from the inside, avoiding obstruction of the motor's outer surface and thus preventing processing disruptions.

[0004] Although the aforementioned patent utilizes a worm gear and worm wheel configuration, where the worm gear controls the rotation of the worm wheel, and the arc-shaped groove inside the worm wheel compresses the fixing rod, causing the connecting block to move smoothly with the grippers under the action of the limiting block, and by controlling the synchronous movement and separation of the three grippers, the motor housing can be securely clamped from the inside, avoiding obstruction of the motor's outer surface and thus preventing processing, the clamping force is not strong enough when clamping the motor housing. The rotation of the worm gear and worm wheel can still loosen, and unstable clamping can lead to relative displacement between the motor and surrounding components, increasing wear, accelerating equipment aging and malfunctions. It is also not convenient to strengthen the clamping force while protecting the surface of the motor housing and reducing damage to the motor housing.

[0005] Therefore, this utility model provides a motor housing clamping device to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This utility model provides a motor housing clamping device, which aims to solve the problems mentioned in the background art.

[0014] As a preferred technical solution of this application, a B magnetic sheet is fixedly connected to the other side of the movable bracket, and a handle is fixedly connected to the surface of the B magnetic sheet.

[0015] (III) Beneficial Effects

[0016] This utility model has a simple structure and is easy to operate.

Then, a reinforcement mechanism is used to reinforce it after clamping, preventing the motor housing from slipping again and causing the clamping mechanism to loosen. The increased clamping force can effectively stabilize the motor, reduce vibration and displacement during operation, and thus improve the reliability of motor operation. While ensuring clamping strength, rubber strips are used to reduce direct friction on the motor housing, thereby extending the service life of the housing. Attached Figure Description

Detailed Implementation

[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] This utility model provides a clamping device, such as Figures 1-4 As shown, this motor housing clamping device includes a base plate 1. A support rod 2 is fixedly connected to one side of the upper surface of the base plate 1, and a clamping mechanism is fixedly connected to one end of the support rod 2. A slide rod 3 is fixedly connected to the other side of the upper surface of the base plate 1. A slider 4 is slidably connected inside the slide rod 3. A buffer spring 5 is fixedly connected to the bottom of the slider 4, and a snap-fit ​​mechanism is fixedly connected to one end of the slider 4. A groove is opened on the outer surface of the slide rod 3, and a reinforcing mechanism is slidably connected inside the groove. When clamping the motor housing, the electric push rod 6 uses the telescopic clamping of the rotating rod 8 to slide the slider 4 inside the slide rod 3. The slider 4 is firmly clamped according to the size of the motor housing. The reinforcing mechanism is used to reinforce the motor housing after clamping to prevent the motor housing from slipping again after clamping, which would cause the clamping mechanism to loosen. The increased clamping force can effectively stabilize the motor, reduce vibration and displacement during operation, and thus improve the reliability of the motor operation. While ensuring the clamping strength, a rubber strip 13 is used to reduce direct friction on the motor housing, thereby extending the service life of the housing.

[0025] The clamping mechanism includes an electric push rod 6. The bottom of the electric push rod 6 is fixedly connected to one end of the support rod 2. One end of the electric push rod 6 is fixedly connected to a frame plate 7. Both sides of the frame plate 7 are rotatably connected to rotating rods 8 via rotating shafts. One end of the rotating rod 8 is fixedly connected to a rotating component 9. When the electric push rod 6 is activated, the electric push rod 6 extends and retracts, causing the frame plate 7 to extend and retract. The frame plate 7 causes the rotating rods 8 and the rotating component 9 to move inward or outward simultaneously, which facilitates clamping the clamping plate 12 to the motor housing.

[0026] The snap-fit ​​mechanism includes a connecting plate 10, one side of which is fixedly connected to one end of the slider 4. Two ends of the bottom of the connecting plate 10 are fixedly connected to spring A 11. One end of spring A 11 is fixedly connected to a snap-fit ​​plate 12. A rubber strip 13 is fixedly connected to the surface of the snap-fit ​​plate 12. A vertical rod 14 is inserted into the inside of spring A 11.

[0027] A connecting piece A 15 is fixedly connected to the outer surface of the upright 14. A spring B 16 is fixedly connected to the upper surface of the connecting piece A 15. A connecting piece B 17 is fixedly connected to one end of the spring B 16. When the rubber strip 13 clamps the motor housing, the snap plate 12 squeezes the spring A 11. The spring A 11 is squeezed onto the connecting plate 10 and the upright 14. When the upright 14 extends or retracts, it squeezes the connecting piece A 15 and the spring B 16. The spring B 16 is squeezed onto the connecting piece B 17, thereby achieving the effect of protecting the motor housing when the clamping force is strengthened.

[0028] The reinforcement mechanism includes a movable bracket 18, the outer surface of which is slidably connected to the inside of the sliding groove on the surface of the slide rod 3, and a magnetic sheet A 19 is fixedly connected to one side of the movable bracket 18.

[0029] A B magnetic sheet 20 is fixedly connected to the other side of the movable bracket 18. A handle 21 is fixedly connected to the surface of the B magnetic sheet 20. After adjusting the clamping size, pull the handle 21 to move the B magnetic sheet 20. When the B magnetic sheet 20 moves, it drives the movable bracket 18 and the A magnetic sheet 19 to move within the slide bar 3, pressing the movable bracket 18 against the surface of the slider 4 for reinforcement. The A magnetic sheet 19 and the B magnetic sheet 20 generate magnetic force and can attract each other to prevent the slider 4 from sliding and affecting the clamping of the motor housing.

[0030] Specifically, when the motor housing needs to be clamped, the electric push rod 6 is activated. As the electric push rod 6 extends and retracts, it causes the frame plate 7 to extend and retract. The frame plate 7 then causes the rotating rod 8 and the rotating component 9 to move inward or outward simultaneously, facilitating the clamping plate 12 to clamp the motor housing. When the rubber strip 13 clamps the motor housing, the clamping plate 12 compresses spring A 11, which in turn compresses the connecting plate 10 and the upright rod 14. During extension and retraction, the upright rod 14 compresses connecting piece A 15 and spring B 16, which in turn compresses connecting piece B 17. This achieves a protective effect on the motor housing while increasing the clamping force, reducing stress on the motor housing. After the motor housing surface is damaged, the clamping size is adjusted, and the handle 21 is pulled to move the B magnetic piece 20. When the B magnetic piece 20 moves, it drives the moving bracket 18 and the A magnetic piece 19 to move within the slide bar 3. The moving bracket 18 is pressed against the surface of the slider 4 for reinforcement. The A magnetic piece 19 and the B magnetic piece 20 generate magnetic force and can attract each other to prevent the slider 4 from sliding and affecting the clamping of the motor housing. Then, when the slider 4 slides, the two sliders 4 simultaneously squeeze the buffer spring 5 to facilitate the buffering effect, increase the buffering effect under the clamping force of the motor housing, and reduce the damage to the surface of the motor housing.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
