Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a clamping device for ultra-precision medical equipment components. Background Technology

[0002] With the continuous development of medical technology and ultra-precision machining technology, medical equipment is moving towards greater precision, efficiency and safety. The manufacturing precision requirements for ultra-precision medical equipment components are getting higher and higher, which also puts forward higher requirements for clamping devices in their processing, testing and assembly. For example, in the fields of high-resolution medical imaging equipment and micro medical devices, the size of the components is smaller and the precision is higher, which requires such a device that can achieve high-precision clamping and effective vibration reduction.

[0003] Traditional devices may lack a precise guiding mechanism when positioning ultra-precise medical equipment components, making it difficult to adapt to the clamping requirements of various shapes. When clamping components with complex shapes, it is difficult to provide a stable clamping force in all directions, which makes the components prone to displacement during operation. Furthermore, it is difficult to protect the clamped parts when encountering vibration or impact, making the components susceptible to damage from low-frequency vibrations. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a clamping device for ultra-precision medical equipment parts.

[0005] This utility model is achieved using the following technical solution: a clamping device for ultra-precision medical equipment parts, including a base, a support shell fixedly connected to the top of the base, and a sliding groove formed inside the base, and further including:

[0006] A clamping mechanism, comprising a servo motor fixedly connected to the inner wall of the bottom of the base, the output end of the servo motor being fixedly connected to a convex shaft, and a limit post being provided on the outside of the convex shaft;

[0007] A buffer structure includes a fixed shell fixedly connected to the inner wall of the bottom of the base, a sliding plate slidably connected to the outside of the fixed shell, and a damper disposed inside the sliding plate.

[0008] As a further improvement to the above solution, the outer side of the convex shaft is slidably connected to a sliding sleeve, the inner side of the support shell is slidably connected to a sliding outer shell, and the top of the sliding outer shell is fixedly connected to a limiting shell.

[0009] The above technical solution provides a stable support frame for the subsequent clamping and shock absorption structure, consisting of a support shell, a sliding shell, and a limiting shell, making the entire device more compact and stable.

[0010] As a further improvement to the above solution, a movable turntable is rotatably connected inside the limiting shell, and a rotating shaft is slidably connected inside the movable turntable. A limiting post is fixedly connected to the top of the rotating shaft, and the limiting post is made of rubber.

[0011] Through the above technical solution, the set limiting shell and the movable turntable enable the power to be effectively transmitted from the sliding sleeve to the movable turntable, and then transmitted to the limiting post through the rotating shaft, so as to realize the precise clamping action of the parts.

[0012] As a further improvement to the above solution, the limiting post is slidably connected inside the limiting shell, and the movable turntable is fixedly connected to the outside of the sliding sleeve.

[0013] As a further improvement to the above solution, a connecting block is rotatably connected inside the sliding plate, a damper is fixedly connected to the bottom of the connecting block, and a spring is fixedly connected to the bottom of the connecting block.

[0014] Through the above technical solution, when subjected to vibration and impact, the connecting block can effectively drive the damper and spring to work. The damper can consume vibration energy, and the spring can absorb vibration energy through elastic deformation. The two work together to buffer and absorb vibration more efficiently, protecting the device and the clamped components.

[0015] As a further improvement to the above solution, a sliding block is slidably connected inside the base, a connecting rod is rotatably connected outside the sliding block, and a connecting shell is fixedly connected to the top of the sliding plate.

[0016] Through the above technical solution, the sliding of the sliding plate can be transformed into the sliding of the sliding block and the rotation of the connecting rod by the sliding block and the connecting shell. Through the linkage of multiple components, the shock absorption effect is more uniform and stable.

[0017] As a further improvement to the above solution, the spring is fixedly connected between the connecting block and the damper, the connecting shell is slidably connected to the outside of the fixed shell, and the end of the connecting rod away from the sliding block is rotatably connected to the outside of the sliding plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention uses a servo motor to drive the cam shaft to rotate, which in turn drives the sliding sleeve to rotate, causing the moving turntable to rotate and the limiting post to move. Ultimately, the limiting post clamps the part, thus achieving the beneficial effect of precise and stable clamping of ultra-precision medical equipment parts. This precise and stable clamping ensures that the parts will not shift or shake during processing, testing, or assembly, guaranteeing the accuracy of related operations.

[0020] This invention effectively absorbs vibration impacts by having the sliding outer shell move to drive the sliding sleeve to slide when encountering vibration or device movement, and the sliding plate to descend through the connecting shell, causing the connecting block to drive the damper to rotate, and the spring to contract and absorb the impact through the damper. This series of structural operations achieves the beneficial effect of reducing the impact of vibration on the clamping device and the clamped parts. This shock-absorbing structure can effectively protect the parts and ensure that their performance is not affected by external vibration factors. Attached Figure Description

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Please combine Figure 1-5 This embodiment of an ultra-precision medical device component clamping device includes a base 1, a support shell 11 fixedly connected to the top of the base 1, a sliding groove 12 formed inside the base 1, and further includes:

[0030] The clamping mechanism 2 includes a servo motor 201 fixedly connected to the inner wall of the bottom of the base 1. The output end of the servo motor 201 is fixedly connected to a convex shaft 202, and a limit post 208 is provided on the outside of the convex shaft 202.

[0031] The buffer structure 3 includes a fixed shell 301 fixedly connected to the inner wall of the bottom of the base 1, a sliding plate 302 slidably connected to the outside of the fixed shell 301, and a damper 304 disposed inside the sliding plate 302.

[0032] The external sliding connection of the convex shaft 202 is a sliding sleeve 203, the internal sliding connection of the support shell 11 is a sliding outer shell 204, and the top of the sliding outer shell 204 is fixedly connected to a limiting shell 205.

[0033] The inner part of the limiting housing 205 is rotatably connected to a movable turntable 206, and the inner part of the movable turntable 206 is slidably connected to a rotating shaft 207. The top of the rotating shaft 207 is fixedly connected to a limiting post 208, and the limiting post 208 is made of rubber.

[0034] The limiting post 208 is slidably connected inside the limiting housing 205, and the movable turntable 206 is fixedly connected to the outside of the sliding sleeve 203.

[0035] The sliding plate 302 is rotatably connected to a connecting block 303, the bottom of the connecting block 303 is fixedly connected to a damper 304, and the bottom of the connecting block 303 is fixedly connected to a spring 305.

[0036] The base 1 has a sliding block 306 inside, and a connecting rod 307 is rotatably connected to the outside of the sliding block 306. The top of the sliding plate 302 is fixedly connected to a connecting shell 308.

[0037] Spring 305 is fixedly connected between connecting block 303 and damper 304, connecting shell 308 is slidably connected to the outside of fixed shell 301, and the end of connecting rod 307 away from sliding block 306 is rotatably connected to the outside of sliding plate 302.

[0038] The implementation principle of the ultra-precision medical equipment component clamping device in this application embodiment is as follows: During operation, the part to be clamped can be placed on the top of the limiting shell 205. At this time, the servo motor 201 can be started to drive the convex shaft 202 to rotate. At this time, the convex shaft 202 drives the sliding sleeve 203, which is slidably connected to the outside of the convex shaft 202, to rotate. At this time, the sliding sleeve 203 can drive the movable turntable 206, which is fixedly connected to the outside of the sliding sleeve 203, to rotate inside the limiting shell 205. At this time, the rotating shaft 207 moves inside the movable turntable 206 and moves towards the center through the limitation of the limiting shell 205, so that the limiting post 208 clamps the part.

[0039] When encountering vibration or when the device is moved, the sliding housing 204 moves and drives the sliding sleeve 203 to slide outside the convex shaft 202. When the sliding housing 204 descends, the sliding housing 204 drives the sliding plate 302 to slide outside the fixed housing 301 and descend through the connecting housing 308. At this time, the connecting rod 307 outside the sliding plate 302 rotates, thereby driving the sliding block 306 to slide inside the sliding groove 12. At the same time, the connecting block 303 connected inside the sliding plate 302 rotates and drives the damper 304 to rotate. At this time, the spring 305 contracts and absorbs the impact through the damper 304, reducing vibration.
