Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a tooling for processing medical device accessories. Background Technology

[0002] Medical device component manufacturing refers to the process of producing key components for medical equipment, instruments, and surgical tools. These components are fundamental parts of medical equipment, and their quality and performance are directly related to patients' health and treatment outcomes. By optimizing material selection, improving processing techniques, and introducing new technologies, the quality and performance of products can be effectively improved to meet the stringent requirements of the medical industry.

[0003] Existing medical device component processing fixtures, when supporting raw materials for processing, have a relatively fixed clamping area, making it difficult to flexibly adapt to raw materials of different lengths. When performing limiting processing on components with larger lengths, due to the limited clamping range, a considerable portion of the area at both ends of the component often cannot be effectively clamped, resulting in a decrease in the overall stability of the component on the fixture. In this state, when the component is subjected to external forces such as cutting forces during processing, it is very easy for the position to shift due to the lack of sufficient support at both ends. This not only affects processing accuracy and product quality but may also increase the scrap rate, causing great inconvenience. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a medical device accessory processing fixture. This fixture addresses the issue mentioned in the background art where existing medical device accessory processing fixtures, due to their relatively fixed clamping area, are unable to flexibly adapt to accessory materials of different lengths. When performing limiting processing on accessories with larger lengths, the limited clamping range often results in a significant portion of the accessory's ends not being effectively clamped, leading to a decrease in the overall stability of the accessory on the fixture. In this state, when the accessory is subjected to external forces such as cutting forces during processing, it is highly susceptible to positional displacement due to insufficient support at both ends. This not only affects processing accuracy and product quality but may also increase the scrap rate, causing considerable inconvenience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a medical device accessory processing fixture, comprising a main body and an extension mechanism disposed on one side of the main body. The main body includes a base plate, and the extension mechanism includes several side frames symmetrically arranged and fixedly connected to one side of the base plate. A positioning screw is threadedly connected to the inner side of each side frame, and a sliding arm is threadedly connected to the outer side of the positioning screw through an adjusting screw hole. A base plate is slidably connected to the outer side of the sliding arm, a support bar is fixedly connected to one side of the sliding arm, several sliders are slidably connected to the inner side of the support bar, a locking screw is threadedly connected to the inner side of each slider, a support bar is slidably connected to the outer side of one end of the locking screw, a sliding screw is fixedly connected to the top of the locking screw, a clamping column is movably connected to the outer side of the sliding screw, and a nut is threadedly connected to the outer side of the top end of the sliding screw.

[0006] Preferably, a plurality of foot pads are symmetrically arranged on the outer side of the substrate, a base is fixedly connected to one side of the top of the substrate, a push screw is threadedly connected to the inner side of the base, a handwheel is fixedly connected to one end of the push screw, an active clamping block is rotatably connected to the outer side of the other end of the push screw, a slide rod is symmetrically arranged on one side of the active clamping block, a base is slidably connected to the outer side of the slide rod, a driven clamping block is fixedly connected to the other side of the top of the substrate, a side plate is fixedly connected to one side of the substrate, a mating screw hole is fixedly connected to one side of the side plate, and a plurality of mating screw holes are symmetrically arranged inside the mating screw hole.

[0007] Preferably, the clamping post is made of rubber, and the clamping post is a drum-shaped structure with the diameters at both ends smaller than the diameter at the middle. A sliding screw is movably connected to the inner side of the clamping post.

[0008] Preferably, several adjusting screw holes are symmetrically arranged, and a positioning screw is threadedly connected to the inner side of one of the adjusting screw holes.

[0009] Preferably, a washer is movably connected to the outer side of one end of both the positioning screw and the locking screw, and the washer is located on one side of the side frame and the support strip, respectively.

[0010] Preferably, sealing plates are attached to both sides of the support strip, and the sealing plates are located on one side of the slider.

[0011] Preferably, an extension platform is fixedly connected to the other side of the support strip, and the tops of the support strip and the extension platform are on the same horizontal line.

[0012] Preferably, the outer surfaces of the positioning screw, the locking screw, and the sliding screw are all provided with an electroplated anti-oxidation coating.

[0013] Compared with the prior art, this utility model provides a tooling for processing medical device accessories, which has the following beneficial effects: 1. This utility model, by setting clamping posts, allows for the removal of various positioning screws by rotating counterclockwise according to the required length of the medical device accessory, thus releasing the restriction on the position of the sliding arm. The sliding arm is then slid within the base plate until the support bar is in the desired horizontal position. The positioning screws are then inserted into the side frame and connected to the corresponding adjusting screw holes to fix the position of the sliding arm. The medical device accessory is placed flat on the top of the base plate, with one side contacting the driven clamping block. Excess length of the medical device accessory is supported by the support bar at both ends. Based on the width of the medical device accessory, the locking screw is rotated counterclockwise to reduce the pressure of the outer wall of the slider against the inner wall of the support bar. The slider is then positioned so that one side of the clamping post contacts both sides of the outer wall of the medical device accessory. The locking screw is then tightened to increase the sliding arm's position. The outer wall of the block presses against the inner wall of the support strip, fixing the slider. The nut at the top of the sliding screw is rotated, causing the nut to descend and press against the clamping column. Due to its material and hollow drum-shaped structure, the middle area of ​​the clamping column expands outward, increasing the pressure between the clamping columns on the outer wall of the medical device accessory, thus completing the fixation. Finally, the corresponding device is installed on one side of the mounting plate through the docking screw hole, and then the active and driven clamping blocks are used to clamp and fix the medical device accessory, and processing begins. It can clamp and limit the two ends of medical device accessories with large length dimensions, effectively reducing the situation where the long-length accessories are subjected to cutting forces and other external forces during processing, and the position shift occurs due to insufficient support at both ends. While ensuring processing accuracy and quality, it also effectively reduces the scrap rate. 2. By setting a gasket, this utility model can effectively reduce the loosening of the positioning screw and locking screw during long-term use, thus ensuring the stability of their positioning ability; 3. By setting up an extension platform, this utility model can further expand the contact area between the medical device accessories and the accessories.

[0014] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

A clamping post 209 is movably connected to the outer side of the sliding screw 208. A nut 210 is threadedly connected to the outer side of the top of the sliding screw 208. According to the length of the medical device accessory to be processed, rotate counterclockwise and remove each positioning screw 202 to release the restriction on the position of the sliding arm 204. Then, slide the sliding arm 204 in the base plate 101 until the support bar 205 is in the required horizontal position. Then, insert the positioning screw 202 into the side frame 201 and connect it with the corresponding adjusting screw hole 203 to fix the position of the sliding arm 204. The medical device accessory is placed flat on the top of the base plate 101, with one side contacting the driven clamp 108.
