Description

Technical Field

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

[0002] The submersible motor housing tightening device eliminates the gap between the submersible motor housing and the stator laminations, ensuring a tight fit between them. This device, through a specific tightening mechanism and guide components, can evenly tighten the motor housing.

[0003] According to the patent application CN 218678781U, "A submersible motor housing tightening device includes a tightening seat and a tightening mechanism; the tightening mechanism is detachably disposed inside the tightening seat and tightens or loosens the submersible motor housing; a limiting component for supporting and limiting the submersible motor housing is movably disposed inside the tightening seat."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model employs a tightening seat and a tightening mechanism. One end of the tightening component is fixedly connected to the tightening seat, and the other end is connected to a cylinder. The cylinder controls the tightening and loosening of the tightening component, enabling the tightening of the submersible motor housing. The rectangular strip structure of the tightening component increases the contact area with the submersible motor housing, reducing damage. However, in actual use, when faced with motor housings of different lengths and sizes, the device only tightens the motor housing by pulling the tightening strips at both ends with the cylinder. This results in a limited contact area between the tightening strips and the motor housing, making it impossible to ensure that all parts of the housing are subjected to uniform pressure. Consequently, uneven force leads to deformation or damage, resulting in poor overall tightening effect of the device. Therefore, an improved submersible motor housing tightening device is needed. Utility Model Content

[0006] The purpose of this utility model is to provide a submersible motor housing tightening device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a submersible motor housing tightening device, including a connecting seat, a connecting plate fixedly connected to the top of the connecting seat, a tightening and unfolding mechanism provided on the front of the connecting plate, and a support mechanism provided on the top of the connecting seat;

[0008] The tightening and unfolding mechanism includes a tightening component and an unfolding component, wherein the unfolding component is disposed inside the tightening component;

[0009] The tightening assembly includes a cylinder, which is fixedly connected to the top of the connecting seat. A push plate is fixedly connected to the output end of the cylinder, and a push rod is fixedly connected to the back of the push plate. A connecting rod is rotatably connected to the back of the push rod, and a rotating ring is rotatably connected to the end of the connecting rod away from the push rod, so as to facilitate uniform tightening of the motor housing.

[0010] Preferably, a groove is provided at the position corresponding to the connecting plate of the push rod, and the push rod is slidably connected in the groove to facilitate synchronous movement of the push rod.

[0011] Preferably, the rotating ring has a hole at the corresponding position of the connecting plate, and the rotating ring is rotatably connected in the hole, which facilitates stable rotation of the rotating ring.

[0012] Preferably, the unfolding assembly includes a sleeve, which is fixedly connected to the inner side of the push rod. A rubber pad is fixedly connected to the inner side of the sleeve. An unfolding plate is slidably connected inside the sleeve. A bolt is threaded inside the unfolding plate. A rubber pad is slidably connected inside the unfolding plate. A spring is fixedly connected between the rubber pad and the unfolding plate, so as to increase the contact area between the rubber pad and the motor housing according to the size of the motor.

[0013] Preferably, the bolt abuts against the outside of the rubber pad, and a groove is provided at the corresponding position of the unfolding plate and the jacket, and the unfolding plate is slidably connected in the groove to facilitate the rapid unfolding of the rubber pad.

[0014] Preferably, the support mechanism includes a sliding sleeve, which is fixedly connected to the top of the connecting seat.

[0016] Compared with the prior art, the present invention provides a submersible motor housing tightening device, which has the following beneficial effects:

[0017] 1. This submersible motor housing tightening device, through a tightening and unfolding mechanism, allows manual pulling of the unfolding plate according to the motor size, thus fully opening the unfolding plate. A starting cylinder then pushes a push plate upwards, causing the rubber pads to gradually approach the motor housing, thereby rapidly tightening the motor housing. This ensures that all parts of the housing are subjected to uniform pressure, preventing deformation or damage to the motor housing due to uneven stress, and further improving the overall tightening effect of the device.

[0018] 2. The submersible motor housing tightening device, through the set support mechanism, allows the motor to be tightened to be placed on the bracket. The motor moves up or down by the spring force or contraction, so that the motor housings of different sizes are aligned between the clips. Then, by manually pushing it into the inner side of the surrounding clips, the operator can easily push the motors of different sizes into the inner side of the tightening and unfolding component, thus facilitating subsequent processing.

[0028] Example 1:

[0029] Please see Figure 1-5 This utility model provides a technical solution: a submersible motor housing tightening device, including a connecting seat 1, a connecting plate 2 fixedly connected to the top of the connecting seat 1, a tightening and unfolding mechanism 3 provided on the front of the connecting plate 2, and a support mechanism 4 provided on the top of the connecting seat 1.

[0030] The tightening and unfolding mechanism 3 includes a tightening component 31 and an unfolding component 32, with the unfolding component 32 disposed inside the tightening component 31;

[0031] The tightening assembly 31 includes a cylinder 311, which is fixedly connected to the top of the connecting seat 1. A push plate 312 is fixedly connected to the output end of the cylinder 311. A push rod 313 is fixedly connected to the back of the push plate 312. A connecting rod 314 is rotatably connected to the back of the push rod 313. A rotating ring 315 is rotatably connected to the end of the connecting rod 314 away from the push rod 313, so as to facilitate the uniform tightening of the motor housing.

[0032] Furthermore, a groove is provided at the corresponding position of the push rod 313 and the connecting plate 2, and the push rod 313 is slidably connected in the groove, which facilitates the synchronous movement of the push rod 313.

[0033] Furthermore, the rotating ring 315 has a hole at the corresponding position of the connecting plate 2, and the rotating ring 315 is rotatably connected in the hole, which facilitates the stable rotation of the rotating ring 315.

[0034] Furthermore, the unfolding assembly 32 includes a sleeve 321, which is fixedly connected to the inside of the push rod 313. A rubber pad 322 is fixedly connected to the inside of the sleeve 321. An unfolding plate 323 is slidably connected inside the sleeve 321. A bolt 324 is threadedly connected inside the unfolding plate 323. A rubber pad 326 is slidably connected inside the unfolding plate 323. A spring 325 is fixedly connected between the rubber pad 326 and the unfolding plate 323, so as to increase the contact area between the rubber pad and the motor housing according to the size of the motor.

[0035] Furthermore, the bolt 324 abuts against the outside of the rubber pad 326, and the unfolding plate 323 is provided with a groove at the corresponding position of the jacket 321, and the unfolding plate 323 is slidably connected in the groove, which facilitates the quick unfolding of the rubber pad 326.

[0036] Example 2:

[0037] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the support mechanism 4 includes a sliding sleeve 41, which is fixedly connected to the top of the connecting seat 1. A telescopic rod 43 is slidably connected inside the sliding sleeve 41. A spring 42 is fixedly connected between the telescopic rod 43 and the sliding sleeve 41. A bracket 44 is fixedly connected to the top of the telescopic rod 43, which facilitates support and lifting before tightening and makes it easier for workers to operate.

[0038] Furthermore, a through groove is provided at the corresponding position of the sliding sleeve 41 and the telescopic rod 43, and the telescopic rod 43 is slidably connected in the through groove, so as to facilitate the telescopic rod 43 to slide up and down.

[0039] In actual operation, when the device is in use, firstly, the motor to be tightened is placed on the bracket 44 through the support mechanism 4. The spring 42 moves the motor upwards or downwards, aligning the motor housings of different sizes with the sleeves 321. Then, by manually pushing the motors into the inner sides of the sleeves 321, the operator can easily push the motors of different sizes into the tightening and unfolding assembly 32. Next, through the tightening and unfolding mechanism 3, the unfolding plate 323 is manually pulled outwards according to the motor size, sliding along the inner side of the sleeves 321 until the rubber pad 326 is completely exposed. Then, the bolt 324 is manually turned, pushing the rubber pad 326 outwards until the rubber pad 326 is at the same height as the rubber pad 322, thus fully unfolding the device. When plate 323 is opened, cylinder 311 pushes push plate 312 upward, which in turn pushes push rod 313 upward. During the upward movement of push rod 313, rubber pad 326 and rubber pad 322 gradually move closer to the motor housing. Simultaneously, during the upward movement of push rod 313, connecting rod 314 moves upward, driving rotating ring 315 to rotate. As rotating ring 315 rotates, it pulls the externally connected connecting rod 314, causing the connecting rod 314 to drive the corresponding push rod 313 to move. This causes the push rod 313 to drive the corresponding rubber pad 322 and rubber pad 326 to move relative to each other, gradually bringing each rubber pad 322 and rubber pad 326 closer to the motor housing, thus allowing the motor housing to be quickly tightened.
