TECHNICAL FIELD
[0001] The utility model relates to medical equipment processing frock technical field, especially a kind of positioner base frock. BACKGROUND
[0002] The positioner base for bone surgery needs high-quality frock to ensure its precision and quality in manufacturing process, whether it is machining link (such as drilling, polishing, etc.) or assembly link.The traditional frock has deficiencies in positioning accuracy, fixing stability, adaptability to different specifications of workpiece and protection of workpiece surface.Simply speaking, inaccurate positioning may lead to subsequent processing size deviation, affecting the installation and use effect of the positioner;Unstable fixation may cause displacement of workpiece during processing, reducing processing precision;Unable to effectively adapt to different specifications of base increases production cost;And the contact mode between frock and workpiece may scratch the surface of workpiece, adversely affecting product quality.
[0003] Therefore, a new type of frock is needed to solve these problems. SUMMARY
[0004] The utility model aims at providing a kind of positioner base frock with the advantages of accurate positioning, firm fixation, protection of workpiece, strong adaptability, easy operation and maintenance, etc., which can effectively solve the problems existing in the processing or assembly process of the existing frock of bone positioner base, meet the needs of high-quality frock in medical industry, to solve the above technical problems.
[0005] To achieve the above technical scheme, the technical scheme of the utility model is as follows:the positioner base frock mainly includes frock body, first protruding part, second protruding part, vertical positioning shoulder, U-shaped profiling groove, second profiling positioning groove, third profiling positioning groove and second U-shaped profiling groove.The frock body serves as the basic structure of the entire frock, providing support for other components.The first protruding part and the second protruding part extend outward from the top of the frock body, and the two form a vertical positioning shoulder between them, and the vertical positioning shoulder is provided with a U-shaped profiling groove, and the top of the second protruding part is provided with a second profiling positioning groove, and the frock body is also provided with a third profiling positioning groove and a second U-shaped profiling groove communicating with one side of the third profiling positioning groove.These structures jointly constitute the positioning and placement space of the bone positioner base, and through the design of different shapes and positions, the accurate placement and positioning of the base are realized.
[0006] Further, the inner wall of the second profiling positioning groove is embedded with deformable parts that can move closer to or away from each other, and under the action of an electric field, the adjacent deformable parts press the locator base towards each other. This design takes advantage of the piezoelectric effect of piezoelectric ceramics, and through the application of an electric field, the locator base is clamped. When the base needs to be fixed, an electric field is applied to cause the deformable parts to deform, thereby tightly clamping the base and ensuring that the base does not move during processing or assembly. When processing or assembly is complete, the electric field is removed and the deformable parts return to their original state, making it easy to remove the base.
[0007] Further, the deformable part includes a first deformable layer, an insulating layer, and a second deformable layer that are sequentially adhered. The second deformable layer and the first deformable layer are both piezoelectric ceramics with variable thickness, and this double-layer piezoelectric ceramic structure can produce more stable and effective deformation under the action of an electric field. One side of the second deformable layer is adhered to a wear-resistant layer with a thickness of 0.5 mm, which can reduce friction and wear between the deformable part and the locator base during clamping and unclamping, protect the surface of the base, and also extend the service life of the deformable part.
[0008] Further, the depth of the third profiling positioning groove is much smaller than the depth of the second U-shaped profiling groove. This depth difference design is based on the shape characteristics of the bone locator base. The profiling positioning grooves of different depths can better adapt to the shape of different parts of the base, making the base more stable on the tooling. The third profiling positioning groove is triangularly provided with an internally recessed columnar groove, which can increase the friction between the base and the third profiling positioning groove, further improving the stability of the positioning. The depth of the U-shaped profiling groove is above the third profiling positioning groove, and its unique position and shape design helps to position and place the base in a specific part.
[0009] Further, the U-shaped profiling groove and the second profiling positioning groove position the bone locator base from different angles and positions. The U-shaped profiling groove can preliminarily position and place one side or part of the base, while the second profiling positioning groove positions the base in another dimension. The two work together to improve the accuracy and comprehensiveness of the positioning, ensuring that the base is in the correct position for processing or assembly on the tooling.
[0010] Further, the first protruding part is provided with a columnar air hole, and the columnar air hole is arrayed with suction holes that communicate with the vertical positioning shoulder. The cross-sectional area of all the suction holes is less than the cross-sectional area of the columnar air hole. When air is drawn through the columnar air hole, a negative pressure is generated at the suction holes due to the difference in cross-sectional area between the suction holes and the columnar air hole, thereby attracting the bone locator base to the vertical positioning shoulder and the related positioning groove. This suction effect can further enhance the stability of the base on the tooling, preventing displacement during processing or assembly due to external forces. At the same time, the design of the suction holes also helps to improve the accuracy of the positioning.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1) The utility model discloses a plurality of profiling structures such as U-shaped profiling grooves, second profiling positioning grooves, third profiling positioning grooves and second U-shaped profiling grooves are designed to position the medical skeleton positioner base from multiple directions and dimensions. The shape and position of these profiling grooves are carefully designed according to the actual shape of the base, which can accurately determine the position of the base on the tooling, effectively avoid positioning deviation, provide accurate reference for machining or assembly operation, greatly improve machining precision and ensure product quality.
[0013] 2) The deformation part in the second profiling positioning groove can tightly extrude the positioner base under the action of the electric field, realizing reliable clamping of the base. At the same time, the adsorption system formed by the columnar air holes and suction holes on the first protruding part further enhances the stability of the base on the tooling. This double fixing mode makes the base not displace or shake during machining or assembly due to external force (such as cutting force during machining and pressure during assembly), ensuring the stability and accuracy of operation.
[0014] 3) The 0.5mm wear-resistant layer on one side of the second deformation layer of the deformation part effectively reduces the friction and wear between the positioner base during clamping and loosening, avoids scratching or damaging the surface of the base, protects the surface quality of the workpiece and improves the qualification rate of the product. At the same time, the adsorption of the base by the suction hole is relatively gentle, reducing the damage to the base caused by hard contact.
[0015] 4) The structure design of the tooling can adapt to medical skeleton positioner bases of different specifications. The profiling positioning grooves of different depths and various shapes can be compatible with bases of different sizes and shapes within a certain range, and the adsorption system of the suction hole and the columnar air hole and the clamping action of the deformation part can also realize stable fixation of bases of various specifications, improve the versatility of the tooling, reduce production cost, and be suitable for various types of skeleton positioner base machining or assembly scenes.
[0016] 5) The operation of the tooling is relatively simple, and can be completed by placing the base, applying an electric field and suction adsorption, which is convenient for operators to use. At the same time, the maintenance work of the tooling is also relatively convenient, and it is easy to operate to check the state of the deformation part, suction hole and positioning groove. After finding the problem, the corresponding parts can be repaired or replaced in time, reducing maintenance cost and repair time, ensuring the continuity of production, being conducive to improving production efficiency, and being suitable for wide application in the medical instrument manufacturing industry.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0020] In order for those skilled in the art to better understand the utility model scheme, the utility model will be further described in detail below with reference to the drawings and specific embodiments.
[0021] Please refer to the accompanying Figure 1 As shown in the figure: a kind of locator base tooling, including tooling body 1;The first protruding part 2 and second protruding part 3 are provided with the first protruding part 2 and second protruding part 3 on the top of the tooling body 1 and extend outward;A vertical positioning shoulder 4 is enclosed between the second protruding part 3 and the first protruding part 2;The vertical positioning shoulder 4 is provided with the U-shaped profiling groove 5 of concave on shoulder;Second profiling positioning groove 6 is provided with the second profiling positioning groove 6 on the top of the second protruding part 3;The third profiling positioning groove 7 is provided on the tooling body 1, and the second U-shaped profiling groove 8 is communicated with one side of the third profiling positioning groove 7. The first protruding part and the second protruding part on the tooling body enclose a vertical positioning shoulder, the U-shaped profiling groove is provided on the vertical positioning shoulder, the second profiling positioning groove is provided on the top of the second protruding part, and the third profiling positioning groove and the second U-shaped profiling groove are communicated with it. These different positions and shape profiling structures position the bone locator base from multiple dimensions. The U-shaped profiling groove can preliminarily position and accommodate the specific part of the base, the second profiling positioning groove further determines the position from the top direction, and the third profiling positioning groove and the second U-shaped profiling groove are matched with the base at different depths and angles according to the shape characteristics of the base. The multi-dimensional profiling design enables the base to be accurately placed on the tooling, effectively avoids the position deviation in the processing or assembly process, provides an accurate starting position for subsequent operation, and guarantees the processing and assembly quality.
[0022] On the basis of the above embodiment, the inner wall of the second profiling positioning groove 6 is embedded with deformable parts 9 that can move closer to or away from each other, and under the action of an electric field, adjacent deformable parts 9 press the bottom of the locator closer to each other. The deformable parts embedded in the inner wall of the second profiling positioning groove can press the bottom of the locator closer to each other under the action of an electric field. This design using piezoelectric ceramics achieves active clamping of the base. During processing or assembly, especially when subjected to external forces (such as cutting force during processing, pressure during assembly), the deformable parts can tightly clamp the base as needed to ensure that the base does not shift, ensuring the stability of the operation and improving the accuracy and reliability of processing and assembly.
[0023] On the basis of the above embodiment, the deformable part 9 includes a first deformable layer, an insulating layer, and a second deformable layer that are sequentially adhered; the second deformable layer and the first deformable layer are both piezoelectric ceramics with thickness deformation; and one side of the second deformable layer is adhered to a 0.5mm wear-resistant layer. The 0.5mm wear-resistant layer pasted on one side of the second deformable layer in the deformable part effectively reduces friction with the base during the process of clamping and releasing the base. This avoids scratches or wear on the surface of the base caused by frequent contact, protects the surface quality of the base, helps to improve the pass rate of the product, and also prolongs the service life of the tool itself, reducing maintenance costs.
[0024] On the basis of the above embodiment, the depth of the third profiling positioning groove 7 is much smaller than the depth of the second U-shaped profiling groove 8; the third profiling positioning groove 7 is provided with a triangularly shaped inner recessed cylindrical groove 71; and the depth of the U-shaped profiling groove 5 is above the third profiling positioning groove 7. The depth of the third profiling positioning groove is much smaller than the depth of the second U-shaped profiling groove, and the third profiling positioning groove is provided with a triangularly shaped inner recessed cylindrical groove. This depth difference and cylindrical groove design makes the base more stable when placed. The cylindrical groove increases the friction between the base and the third profiling positioning groove, further limiting the freedom of the base on the tool, and cooperates with other profiling grooves to improve the stability of the overall positioning and reduce processing errors that may be caused by shaking or displacement.
[0025] On the basis of the above embodiment, the first protruding part 2 is provided with a cylindrical air hole; and the cylindrical air hole is provided with an array of suction holes that are communicated with the vertical positioning shoulder 4. The design of the cylindrical air hole on the first protruding part and the suction holes communicated therewith, and the total cross-sectional area of the suction holes being smaller than the cross-sectional area of the cylindrical air hole, causes negative pressure adsorption of the base at the suction holes when air is extracted. This adsorption effect, combined with the clamping effect of the deformable part, forms a double fixation mechanism, further enhancing the stability of the base on the tool, allowing the base to remain stable in a complex processing or assembly environment and effectively preventing loosening caused by accidental external forces.
[0026] On the basis of the above embodiment, the total cross-sectional area of all the suction holes is less than the cross-sectional area of the columnar air hole.
