Description

Technical Field

[0001] The utility model relates to the technical field of medical instrument processing auxiliary equipment, in particular to a positioner slider tooling used for processing and clamping a bone installation positioner. Background Art

[0002] During the manufacturing process of bone-mounted positioners, they must be precisely positioned and securely clamped to ensure machining accuracy and quality. Traditional clamping fixtures often suffer from inaccurate positioning, uneven clamping force, difficulty adapting to positioner slides of varying shapes and sizes, and an inability to perform fine adjustments. This not only affects machining accuracy but can also lead to unstable product quality and increased scrap rates.

[0003] In view of this, it is of great practical significance to develop an efficient and precise tooling specifically for the processing and clamping of bone mounting locators. Summary of the Invention

[0004] The purpose of this utility model is to provide a locator slider tooling with the advantages of reasonable structure, complete functions, easy operation, high precision and strong durability, which can effectively meet various needs in the processing of bone installation locators and provide reliable guarantees for improving processing quality and efficiency, so as to solve the above technical problems.

[0005] In order to realize the above technical solution, the technical solution of the utility model is as follows: a positioner slider tooling, comprising a main body; a first profiling groove and a second profiling groove of an inner groove are provided on the main body; the first profiling groove and the second profiling groove are connected on one side; the depth of the second profiling groove is much greater than the depth of the first profiling groove; an extrusion component is movably provided on the main body; the extrusion component can drive one side of the second profiling groove to deform and clamp; an adjustment component that can be adjusted along the vertical direction is provided at the bottom of the second profiling groove.

[0006] Furthermore, the extrusion component includes a rotating screw rotatably arranged on the body; an extrusion slider is screwed onto the rotating screw; an elastic member is provided on one side of the extrusion slider; and an inclined extrusion surface is provided on one side of the extrusion slider.

[0007] Furthermore, the second profiling groove is symmetrically provided with deformation grooves; a pressing arm is provided between adjacent deformation grooves; and one side of the pressing arm is arranged in a trapezoidal shape.

[0008] Furthermore, the extrusion surface of the pressing arm is coated with a 0.2 μm wear-resistant coating on one side; and the height of the deformation groove is 1 mm.

[0009] Furthermore, the adjustment component includes an insulating layer, a first deformable layer adhered to the left side of the insulating layer, and a second deformable layer adhered to the right side, the first deformable layer and the second deformable layer are both piezoelectric ceramics with varying thickness; under the action of an electric field, the first deformable layer and the second deformable layer both deform along the thickness.

[0010] Furthermore, a wear-resistant layer with a thickness of 0.1 microns is sprayed on the inner side surfaces of the first profiling groove and the second profiling groove.

[0011] Furthermore, the first contoured groove is provided with an array of dense vacuum lips.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1) The utility model can perform high-precision positioning and clamping of the skeletal mounting locator slider through the contoured design of the first contoured groove and the second contoured groove and the precise clamping action of the extrusion component. The different depths and connection settings of the first contoured groove and the second contoured groove can better adapt to the complex shape of the locator slider and provide stable support and preliminary positioning for it. The cooperation between the rotating screw and the extrusion slider of the extrusion component, plus the buffering effect of the elastic part, enables the clamping force to be precisely controlled, ensuring that the locator slider will not be displaced or shaken during the processing, thereby greatly improving the processing accuracy and quality; the piezoelectric ceramic design of the adjustment component can achieve precise fine-tuning of the height of the locator slider, further improving the processing accuracy. This high-precision positioning, clamping and fine-tuning function can meet the strict requirements of the skeletal mounting locator for processing accuracy, reduce processing errors caused by inaccurate positioning or loose clamping, and improve the product qualification rate and consistency.

[0014] 2) The wear-resistant layer on the inner surfaces of the first and second contoured grooves, as well as the wear-resistant coating on the extrusion surface of the clamping arm, effectively improves the wear resistance of the fixture. During frequent use, friction between the fixture and the positioner slider occurs. The wear-resistant layer and coating reduce the wear on the fixture caused by this friction, thereby extending the tooling's service life. This not only reduces equipment replacement costs but also ensures that the fixture maintains excellent positioning and clamping performance during long-term use, reducing the problem of reduced processing accuracy caused by tooling wear.

[0015] 3) The elastic element design of the extrusion component of this utility model plays a crucial role in the clamping process. It provides stable clamping force, ensuring the positioner slider is securely fixed to the tooling. Furthermore, during the clamping and machining process, when subjected to external impact or vibration, the elastic element acts as a buffer, absorbing some of the energy and preventing damage to the positioner slider caused by excessive impact. This stable clamping force and buffering protection help protect the integrity and precision of the positioner slider, improving machining reliability and safety.

[0016] 4) The adjustment component utilizes a non-contact adjustment method using electric field-controlled piezoelectric ceramics, offering fast response and high precision. During processing, if the height of the positioner slider needs to be fine-tuned, the piezoelectric ceramic can be deformed by rapidly changing the electric field strength, allowing for quick and accurate adjustment of the positioner slider. This non-contact adjustment method avoids the tedious and time-consuming nature of traditional mechanical adjustment methods, significantly improving processing efficiency. Furthermore, the high deformation accuracy of the piezoelectric ceramics enables adjustments to even tiny dimensions, meeting the requirements of high-precision machining.

[0017] 5) The densely packed vacuum lip design on the first contoured groove provides additional suction force for the locator slider, enhancing its stability on the tooling. During processing, even with external disturbances or vibrations, the vacuum lip's suction keeps the locator slider in place without shifting or jumping. This helps ensure process stability and continuity, improves processing quality, and reduces defects and scrap caused by locator slider displacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] Please see the attached Figures 1 to 2 The present invention discloses a positioner slider tooling, comprising a main body 1; a first contoured groove 2 and a second contoured groove 3, each of which is connected to the first contoured groove 2 and the second contoured groove 3; a depth of the second contoured groove 3 being significantly greater than that of the first contoured groove 2; a movably disposed extrusion component 4 on the main body 1; the extrusion component 4 is configured to deform and clamp one side of the second contoured groove 3; and a vertically adjustable adjustment component 5 is disposed at the bottom of the second contoured groove 3. In this embodiment, the contoured design of the first and second contoured grooves, combined with the precise clamping action of the extrusion component, enables high-precision positioning and clamping of the skeletal mounting positioner slider. The varying depths and interconnectedness of the first and second contoured grooves better accommodate the complex shapes of the positioner slider, providing stable support and initial positioning. The combination of the extrusion component's rotating screw and the extrusion slider, combined with the cushioning action of the elastic element, allows for precise control of the clamping force, ensuring that the positioner slider does not shift or wobble during machining, thereby significantly improving machining accuracy and quality.

[0024] Based on the above embodiment, the extrusion component 4 includes a rotating screw 41 rotatably arranged on the main body 1; an extrusion slider 42 is screwed onto the rotating screw 41; an elastic member 43 is provided on one side of the extrusion slider 42; and an inclined extrusion surface is provided on one side of the extrusion slider 42.

[0025] Based on the above embodiment, deformation grooves 31 are symmetrically provided on the second profiling groove 3 ; pressing arms 32 are provided between adjacent deformation grooves 31 ; and one side of the pressing arm 32 is arranged in a trapezoidal shape.

[0026] Based on the above embodiment, the extrusion surface of the pressing arm 32 is coated with a 0.2 μm wear-resistant coating; the height of the deformation groove 31 is 1 mm.

[0027] Based on the above embodiment, the adjustment component 5 includes an insulating layer 51, a first deformable layer 52 adhered to the left side of the insulating layer 51, and a second deformable layer 53 adhered to the right side. The first deformable layer 52 and the second deformable layer 53 are both piezoelectric ceramics with varying thicknesses; under the action of an electric field, the first deformable layer 52 and the second deformable layer 53 are both deformed along the thickness. In this embodiment, the first deformable layer 52 and the second deformable layer 53 of the adjustment component are both designed with piezoelectric ceramics to achieve precise fine-tuning of the height of the locator slider, further improving the processing accuracy. This high-precision positioning, clamping and fine-tuning function can meet the strict requirements of the bone-mounted locator for processing accuracy, reduce processing errors caused by inaccurate positioning or loose clamping, and improve the product qualification rate and consistency.

[0028] Based on the above embodiment, the inner surfaces of the first and second contoured grooves 2 and 3 are sprayed with a wear-resistant layer with a thickness of 0.1 microns on one side. The wear-resistant layer on the inner surfaces of the first and second contoured grooves, as well as the wear-resistant coating on the extrusion surface of the clamping arm, effectively improves the wear resistance of the tooling. During frequent use, friction occurs between the tooling and the positioner slider. The wear-resistant layer and coating reduce the wear on the tooling caused by this friction, thereby extending the tooling's service life. This not only reduces equipment replacement costs but also ensures that the tooling maintains excellent positioning and clamping performance during long-term use, reducing the problem of reduced processing accuracy caused by tooling wear.

[0029] Building on the above-mentioned embodiment, a dense array of vacuum lips is provided on the first contoured groove 2. This dense array of vacuum lips provides additional suction force to the locator slider, enhancing its stability on the tooling. During machining, even with external interference or vibration, the vacuum lips maintain the locator slider in place, preventing displacement or jitter. This helps ensure machining stability and continuity, improves machining quality, and reduces defects and scrap caused by locator slider displacement.

[0030] The utility model is useful as follows: 1) Positioning the locator slider: Carefully place the locator slider, mounted on the bone to be processed, within the first and second contoured grooves of the main body. Based on the shape and size of the locator slider, ensure that it fits the contoured grooves as closely as possible to achieve initial positioning. During placement, care should be taken to avoid collisions with other parts of the tooling to prevent damage to the tooling or the locator slider. 2) Clamping: The extrusion slider is moved toward the second contoured groove by rotating the rotating screw of the extrusion component. The inclined extrusion surface of the extrusion slider gradually compresses the side of the second contoured groove. Due to the presence of the deformation groove, the side deforms, allowing the clamping arm to tightly clamp the locator slider. During the screw rotation process, the operator should control the rotation speed and force according to actual conditions, while observing the clamping state of the locator slider to ensure a secure and uniform clamping. The appropriate clamping force can be determined by feel or using appropriate testing tools to avoid excessive clamping that may cause deformation or damage to the locator slider. Sufficient clamping force should also be ensured to prevent displacement of the locator slider during processing. 3) Height Fine Adjustment: If fine-tuning of the locator slider's height is required during machining, the component can be adjusted using electric field control. Based on the machining accuracy requirements, an electric field of appropriate strength is applied to the first and second deformation layers, causing the piezoelectric ceramic to deform, thereby raising or lowering the bottom of the second contoured groove. During the adjustment process, the locator slider's height changes should be closely observed, and real-time measurements should be taken using measuring tools such as a micrometer to ensure that the required adjustment accuracy is met. Repeated fine adjustments can be made until the desired height position is achieved. 4) Machining Operation: After the locator slider is clamped and height adjusted, machining operations such as drilling, milling, and grinding can be performed. During machining, the operator should closely monitor the machining process to ensure smooth progress. Furthermore, the clamping status and position of the locator slider should be regularly checked for changes. If any abnormalities are detected, the process should be stopped and adjusted immediately. 5) Release and Removal: After machining is completed, the lead screw is rotated in the opposite direction to release the squeeze slider from the side of the second contoured groove, releasing the clamping of the locator slider. The processed positioner slider can then be carefully removed from the tooling, taking care to avoid damaging the positioner slider and the tooling. This positioner slider tooling for clamping bone mounting positioners has the advantages of a reasonable structure, complete functions, easy operation, high precision, and strong durability, and can effectively meet various needs in the bone mounting positioner processing process.
