Description

Technical Field

[0001] The utility model relates to the technical field of medical instrument processing fixtures, in particular to a medical puller handle fixture used for processing medical pullers. Background Art

[0002] During the processing of medical detangler handles, precise positioning and secure fixation are essential to ensure accuracy and quality. Traditional fixtures can suffer from inaccurate positioning, unstable fixation, an inability to adapt to handles of varying sizes, and a lack of flexibility. These issues not only affect processing accuracy but can also lead to low production efficiency and inconsistent product quality.

[0003] In view of this, it is of great significance to develop and design an efficient, precise and reliable fixture specifically for the processing of medical tapper handles. Summary of the Invention

[0004] The purpose of the utility model is to provide a medical puller handle clamp which has the advantages of reasonable structure, practical functions, simple operation, high precision and good stability, which can effectively meet various requirements in the processing of medical puller handles and improve the processing quality and production efficiency of the handles, so as to solve the above technical problems.

[0005] To achieve the above technical solution, the technical solution of the utility model is as follows: the fixture mainly includes a base and a contouring jig arranged in an array on the base. The base provides a stable support foundation for the entire fixture, and the contouring jig is used to position and fix the puller handle to meet processing requirements.

[0006] The profiling jig's long, rectangular body is equipped with concave first and second locating shoulders, as well as a placement surface. These shoulders connect to the placement surface, ensuring the puller handle is accurately placed on the surface. The locating shoulders provide initial positioning and limiting, ensuring the handle's stable position during processing.

[0007] The long strip body is also provided with a fixing portion and a second fixing portion arranged perpendicular to the fixing portion. The fixing portion is connected to the surface of the placement table and is used to further fix the handle to ensure that it will not be displaced or rotated during the processing process.

[0008] The fixing part and the second fixing part adopt a similar structural design and include a vacuum generator, an elastic suction cup and a muffler.

[0009] The vacuum generator is sealed and inserted into the long strip body. Its function is to generate negative pressure. When the vacuum generator is activated, a negative pressure environment is formed inside the elastic suction cup.

[0010] An elastic suction cup is embedded in the elongated body, with one end extending beyond it and connected to the vacuum generator via a pipeline. Under negative pressure, the elastic suction cup securely holds the handle of the puller on the surface, providing stable retention. The elastic suction cup array is placed on the surface, and the combined cross-sectional area of ​​all the cups is significantly smaller than the vacuum generator's air inlet. This ensures that when the vacuum generator is operating, sufficient negative pressure is generated at the cups to effectively hold the handle.

[0011] The muffler is screwed onto the end of the vacuum generator's output airflow to reduce the airflow velocity and silence the noise. During the operation of the vacuum generator, airflow noise is generated. The muffler can effectively reduce noise pollution and provide a relatively quiet working environment.

[0012] The tabletop is sprayed with a 0.1-micron-thick wear-resistant coating. This coating reduces friction and wear between the puller handle and the tabletop, protecting the handle surface from damage and extending the life of the fixture. During processing, the handle will be moved or adjusted on the tabletop, and the wear-resistant coating ensures that this operation does not adversely affect the handle surface quality or the fixture.

[0013] A micro-adjustment section is located between adjacent bases and profiling jigs. This allows for fine-tuning of the profiling jig's position on the base to accommodate the processing requirements of puller handles of varying sizes and shapes. This section allows for precise adjustment of the profiling jig's position and angle, enhancing the jig's versatility and adaptability, ensuring optimal positioning and securing of the handle, and ultimately improving processing accuracy and quality.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1) The design of the first and second positioning shoulders and the placement surface on the elongated body enables precise contour positioning of the medical extractor handle, providing an accurate positioning foundation for processing. The handle fits tightly against the positioning shoulders on the placement surface, limiting its displacement in multiple directions and ensuring a stable position during processing, significantly improving processing precision and quality. Compared with traditional fixtures, this fixture can better ensure the processing accuracy of the handle and reduce dimensional and shape errors caused by inaccurate positioning.

[0016] 2) The fixing unit utilizes a combination of a vacuum generator and an elastic suction cup, ensuring stable suction and fixation of the handle. Under vacuum, the elastic suction cup evenly applies suction force to the handle surface, firmly securing it to the tabletop. This stable fixing method effectively ensures the stability and continuity of the machining process, avoiding defects and increased scrap caused by a loose handle, thereby improving production efficiency and maintaining consistent product quality.

[0017] 3) A wear-resistant coating sprayed onto the tabletop reduces friction and wear between the handle and the tabletop. This not only protects the handle's surface quality, preventing scratches and wear during processing, but also extends the life of the fixture. Over long-term use, the wear-resistant coating effectively resists friction and scratches from the handle, maintaining the flatness and finish of the tabletop, and ensuring the fixture consistently provides excellent positioning and securing. This helps reduce production costs and improve efficiency, while also ensuring product quality and stability.

[0018] 4) The micro-adjustment section between adjacent bases and contoured jigs provides greater adaptability. This allows for precise positional adjustments to puller handles of varying sizes and shapes, ensuring the jig can accommodate a wide variety of handle sizes. This micro-adjustment feature enhances the jig's versatility and flexibility, reducing adjustment time and costs associated with handle mismatches, thereby improving production efficiency and machining accuracy.

The handle can closely mate with the positioning shoulders on the placement table, limiting its displacement in multiple directions and ensuring that the handle remains stable during processing, thereby greatly improving processing accuracy and quality. Compared with traditional fixtures, this fixture can better ensure the processing accuracy of the handle and reduce dimensional deviation and shape error caused by inaccurate positioning.

[0024] Based on the above embodiment, the fixing portion 24 has a similar structural design to the second fixing portion 25; the placement table 26 is sprayed with a 0.1-micron-thick wear-resistant coating. This wear-resistant coating reduces friction and wear between the handle and the placement table, protecting the handle's surface quality and preventing defects such as scratches and wear during processing while also extending the life of the fixture. Over long-term use, the wear-resistant coating effectively resists friction and scratches from the handle, maintaining the flatness and finish of the placement table and ensuring the fixture consistently provides excellent positioning and fixing. This helps reduce production costs, improve production efficiency, and ensure product processing quality and stability.

[0025] Based on the above embodiment, the fixing portion 24 includes:

[0028] The muffler is screwed onto the end of the air flow output by the vacuum generator and is used to reduce the air flow speed and silence the sound.

[0029] Based on the above embodiment, the elastic suction cup array is arranged on the placement table 26, and the sum of the cross-sectional areas of all the elastic suction cups is much smaller than the air inlet of the vacuum generator.

[0030] Based on the above embodiment, a fine adjustment portion 3 is provided between the adjacent base 1 and the profiling jig 2 .

[0031] The utility model is useful as follows: Handle placement: Place the handle of the medical puller to be processed on the placement surface of the contoured jig so that it aligns with the first and second positioning shoulders to achieve preliminary positioning. During the placement process, pay attention to the direction and position of the handle to ensure accurate placement. Securing operation: Activate the vacuum generator to generate negative pressure on the elastic suction cup, which then holds the puller handle. Ensure that the handle is securely held and does not shift or loosen. The securing effect can be checked by observing the suction state of the elastic suction cup or performing a simple tensile test. Processing operation: After the handle is secured, the corresponding processing operation, such as cutting, grinding, and drilling, can be performed. During the processing, closely monitor the working state of the fixture to ensure that the handle is in a stable position. If necessary, the fixture can be adjusted appropriately during processing to ensure processing accuracy. Release and removal: When processing is complete, turn off the vacuum generator, the negative pressure from the elastic suction cup disappears, and the handle is released. Carefully remove the processed handle from the fixture, taking care to avoid damaging the handle and the fixture. The entire design has the advantages of reasonable structure, practical functions, easy operation, high precision and good stability. It can effectively meet various requirements in the processing of medical detangler handles and provide a reliable guarantee for improving the processing quality and production efficiency of the handles.
