Description

Technical Field

[0001] The utility model relates to the field of medical equipment processing tooling, in particular to an ankle joint clamp adjustable knob tooling used for positioning and clamping the ankle joint clamp knob during the production process. Background Art

[0002] The manufacturing process of adjustable knobs for ankle clamps requires precise positioning and clamping to ensure machining accuracy and quality. However, traditional tooling often suffers from issues such as inaccurate positioning, unadjustable clamping force, and surface damage, making it difficult to meet the requirements for high-quality ankle clamp production. Therefore, developing a novel ankle clamp tooling is crucial. Summary of the Invention

[0003] The purpose of the utility model is to provide an ankle clamp adjustable knob tooling with the advantages of novel structure, precise positioning, adjustable clamping force, protection of workpiece, extended tooling life and improved work efficiency, which can meet various needs in the ankle clamp processing process and solve the above technical problems.

[0004] In order to realize the above-mentioned technical solution, the technical solution of the present invention is as follows: The joint clamp adjustable knob tool mainly includes a long strip-shaped body. The body serves as the basic structure of the entire tool and provides a platform for installation and support of other components. A columnar first contoured placement groove is provided in the top array of the body. The first contoured placement groove is used to place a specific part of the ankle clamp adjustable knob. The contoured design can achieve preliminary positioning to ensure the accuracy and stability of workpiece placement. A second contoured placement groove is also provided on the top of the body. The second contoured placement groove passes through the first contoured placement groove, and its depth is much lower than the depth of the first contoured placement groove. The second contoured placement groove is used to accommodate other key structural parts of the ankle clamp. Its special depth design helps to better adapt to the workpiece without affecting the function of the first contoured placement groove. A clamping part that can deform radially is provided between adjacent first contoured placement grooves. The clamping part can apply clamping force to the ankle clamp placed in the first contoured placement groove as needed to ensure that the workpiece will not be displaced during the processing process.

[0005] Furthermore, the cross-section of the second contoured placement groove is an isosceles trapezoidal shape, with an angle α of 0.5°. This unique trapezoidal angle design allows the second contoured placement groove to more precisely adapt to the shape of the ankle clamp, providing better positioning. The second contoured placement groove is also sprayed with a 0.1-micron wear-resistant coating. This wear-resistant coating effectively reduces wear on the workpiece surface during placement and removal of the ankle clamp, protecting the workpiece quality. It also extends the service life of the tooling, preventing wear of the second contoured placement groove due to long-term use, which could affect positioning accuracy.

[0006] Furthermore, the clamping portion includes a deformable clip, a deformable extrusion rod and a lifting push rod installed on the first contoured placement groove. The deformable clip is arranged in an arc shape, and a triangular extrusion surface is provided on one side. The arc-shaped design can better fit the shape of the ankle clamp, and the triangular extrusion surface can more effectively transfer the force to the workpiece when subjected to external force, thereby realizing the clamping function. A deformable extrusion rod is connected to one side of the deformable clip, and the deformable extrusion rod can be inserted into the main body through a spring. The setting of the spring enables the deformable extrusion rod to reset after being subjected to external force. The top of the deformable extrusion rod is arranged in an equilateral triangle shape, and this shape design is conducive to the transmission and conversion of force between the lifting push rod and the lifting push rod. The lifting push rod includes a rotating screw rotatably mounted on the main body, a lifting block is sleeved on the rotating screw, and an extrusion slope is provided on one side of the lifting block. When the screw rotates, the lifting block moves up and down along the screw, and contacts the equilateral triangle at the top of the deformed extrusion rod through the extrusion slope, converting the linear motion of the lifting block into extrusion of the deformed extrusion rod, thereby causing the deformed clamp to produce radial deformation, thus achieving the clamping or loosening operation of the ankle joint clamp. By adjusting the rotation direction and angle of the screw, the size of the clamping force can be precisely controlled to meet different processing requirements.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1) Precise Contour Positioning Improves Processing Accuracy: The design of the first and second contour placement slots on the main body enables precise contour positioning of the ankle clamp. This positioning method ensures the ankle clamp is accurately positioned in the tooling, reducing processing errors caused by positioning deviations during processing, thereby improving the processing accuracy of the ankle clamp and ensuring product quality.

[0009] 2) Adjustable clamping force protects the workpiece and adapts to various processing requirements: The unique design of the clamping unit enables precise adjustment of the ankle clamp's clamping force. By rotating the screw, the movement of the lifting push rod is controlled, thereby adjusting the clamping force of the deformable clip. This adjustable clamping method provides the appropriate clamping force for different processing techniques, ankle clamps of different materials, and sizes, preventing damage to the workpiece caused by excessive clamping force. It also ensures that the workpiece will not shift during processing due to insufficient clamping force, thereby improving the versatility and adaptability of the tooling.

[0010] 3) Wear-resistant coating extends tool life: The 0.1-micron wear-resistant coating on the second contoured placement slot effectively reduces friction and wear between the ankle clamp and the tool. During frequent workpiece placement and removal, the wear-resistant coating protects the surface quality of the second contoured placement slot, extending the tool life and reducing production costs while also ensuring the workpiece's surface quality is not affected by wear.

[0011] 4) Compact and Reasonable Structure Improves Work Efficiency: The overall structure of this ankle clamp with adjustable knob is compact and reasonable, and the various components work closely and efficiently. During use, the operator can easily place, clamp, and remove the ankle clamp, and adjusting the clamping force is also simple and intuitive. This structural design improves the tool's ease of use and work efficiency, contributing to improved ankle clamp production efficiency.

[0012] To sum up, the adjustable knob tooling of the ankle clamp has the advantages of novel structure, precise positioning, adjustable clamping force, protection of workpiece, extended tooling life and improved work efficiency. It can meet various needs in the ankle clamp processing process and provide a strong guarantee for improving the manufacturing quality and production efficiency of the ankle clamp.

[0016] 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.

[0017] 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.

[0018] Please see the attached Figures 1 to 2As shown: An ankle clamp adjustable knob tooling, comprising a long strip-shaped body 1; a columnar first contoured placement groove 2 is provided in an array on the top of the body 1, for providing a accommodating cavity for the adjustable knob and positioning it at the same time; a second contoured placement groove 3 is provided on the top of the body 1, for secondary positioning of both sides of the adjustable knob; the second contoured placement groove 3 passes through the first contoured placement groove 2, and the depth is much lower than the depth of the first contoured placement groove 2; a radially deformable clamping portion 4 is provided between adjacent first contoured placement grooves 2, for further clamping the adjustable knob to ensure processing stability.

[0019] Based on the above embodiment, the cross section of the second profiling placement groove 3 is arranged in an isosceles trapezoidal shape, and the angle α is 0.5°; the second profiling placement groove 3 is sprayed with a 0.1 micron wear-resistant coating.

[0020] Based on the above embodiment, the clamping part 4 includes a deformable clip 41 installed on the first contoured placement groove 2; a deformable extrusion rod 42 is connected to one side of the deformable clip 41; and the end of the deformable extrusion rod 42 is in linear contact with a lifting push rod 43.

[0021] Based on the above embodiment, the deformable clip 41 is arranged in an arc shape, and a triangular extrusion surface is provided on one side.

[0022] On the basis of the above embodiment, the deformable extrusion rod 42 can be inserted into the main body 1 through a spring; the top of the deformable extrusion rod 42 is set in an equilateral triangle shape.

[0023] Based on the above embodiment, the lifting push rod 43 includes a rotating screw rod rotatably mounted on the body 1; a lifting block is sleeved on the rotating screw rod.

[0024] Based on the above embodiment, one side of the lifting block is provided with an extrusion slope.

[0025] To install the present invention: Place the ankle clamp's adjustable knob fixture on a suitable processing workbench, ensuring that the main body is placed stably and securely in place. The fixture can be connected to the workbench using bolts or other fixing methods to prevent movement during processing. Check that the shape and dimensions of the first and second contoured placement slots meet design requirements, ensuring they are free of debris and have smooth surfaces. Also, check that all clamping components, including the deforming clip, deforming extrusion rod, and lifting push rod, are correctly installed, that the spring is in place and elastic, and that the screw can rotate freely. Next, perform debugging. Without the ankle clamp in place, manually rotate the screw of the lifting push rod and observe the deformation of the deforming clip. Verify that the deforming clip can smoothly deform radially under the action of the lifting push rod and that the spring can return to its original shape when the screw is rotated in the opposite direction. Adjust the screw's rotation angle and stroke, and measure the clamping force of the deforming clip on the simulated ankle clamp specimen at different positions to establish a relationship between screw position and clamping force. Based on the actual clamping force requirements for the process, appropriate screw operating parameters are determined to ensure the tooling can accurately provide the required clamping force. Finally, the product is carefully placed within the first and second contoured placement slots on the top of the main body. During placement, ensure that all parts of the ankle clamp precisely align with the contoured placement slots, utilizing the contoured design of the first and second contoured placement slots to achieve initial positioning. To initiate the clamping operation, the lifting block moves upward or downward along the screw by rotating the lifting push rod. As the lifting block moves, its extrusion bevel contacts the equilateral triangle at the top of the deformed extrusion rod, pushing the deformed extrusion rod toward the first contoured placement slot. The deformed extrusion rod then compresses the deformed clip, causing it to deform radially. The triangular extrusion surface gradually closes in on the ankle clamp, clamping it securely. Based on the process requirements, the screw rotation angle is adjusted to achieve the appropriate clamping force, ensuring the ankle clamp is securely fixed to the tooling during processing.

Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art should be able to utilize the technical contents disclosed above and make equivalent embodiments that are equivalent changes by making slight changes or modifications without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
