Description

Technical Field

[0001] This application relates to the field of machining fixing mechanism technology, specifically to a tool machining fixture and tool machining mechanism. Background Technology

[0002] Currently, when polishing or other machining processes are required on the cutting edges of workpieces such as cutting tools, the operator typically holds the workpiece and brings the cutting edge against the polishing wheel for machining. However, due to varying operator experience, the angle of the cutting edge after machining can be inconsistent, and the coating on the cutting edge can easily be over-machined, resulting in lower precision of the machined workpiece. Utility Model Content

[0003] In view of the above, it is necessary to propose a tool machining fixture and tool machining mechanism to improve the accuracy of workpiece machining.

[0004] This application provides a tool machining fixture, including a positioning component and a cover component. The cover component is detachably mounted on the positioning component, and a positioning space is provided between the cover component and the positioning component. The positioning space is used to position a workpiece. The cover component is provided with a machining clearance groove and a machining protrusion. The machining clearance groove is located on the side of the cover component opposite to the positioning component. The machining protrusion penetrates the cover component and communicates with the machining clearance groove. The machining protrusion is used to communicate with the positioning space and also to allow the end of the workpiece to be machined to extend out.

[0005] In some embodiments, the processing clearance groove has a bottom wall with a first end and a second end opposite to each other, the processing opening is provided corresponding to the first end, and the bottom wall is inclined downward from the second end toward the first end.

[0006] In some embodiments, the positioning component includes a positioning member, the cover pressing component is detachably covered on the positioning member, the positioning member has a positioning groove on one side facing the cover pressing component, the positioning groove and the cover pressing component enclose the positioning space, and the processing exposed opening communicates with the positioning groove.

[0007] In some embodiments, the positioning component further includes a support member disposed on the side of the positioning component facing the cover assembly. The support member has a support surface disposed opposite to the processing protrusion and is used to support the portion of the end to be processed located at the processing protrusion.

[0008] In some embodiments, the support member has a clearance groove on the side facing the cover assembly, and the clearance groove is located in the extending direction of the machining clearance groove.

[0009] In some embodiments, the support member is further provided with a limiting groove on the side facing the cover assembly. The limiting groove is located on one side of the clearance groove and is used to limit the structure of the end to be processed away from the processing opening.

[0010] In some embodiments, the portion of the cover assembly near the processing exposure includes a wear-resistant structure, the processing exposure extending through the wear-resistant structure.

[0011] In some embodiments, the cover assembly includes a cover member and a guide member. The cover member is detachably covered by the positioning member. The guide member is located on the side of the cover member facing the positioning member. The guide member is the wear-resistant structure and is disposed opposite to the support member. The machining clearance groove includes a first sub-groove and a second sub-groove that are connected to each other. The first sub-groove is located on the side of the cover member away from the positioning member. The second sub-groove is located on the guide member. The machining protrusion passes through the portion between the side of the guide member facing the positioning member and the end of the bottom wall of the second sub-groove away from the first sub-groove.

[0012] In some embodiments, the guide member has a pressing surface on the side facing the support member, the pressing surface being disposed opposite to the support surface, and the pressing surface being used to press the end to be processed against the support surface.

[0013] In some embodiments, the cover assembly includes a cutting edge located at the processing opening, the cutting edge being disposed around the processing opening, the cutting edge being arc-shaped to conform to the cutting edge to be processed on the workpiece.

[0014] In some embodiments, the tool machining fixture further includes a locking assembly, which includes a locking drive and a clamping member. The locking drive is disposed on the positioning assembly and has a retractable drive shaft that passes through the positioning assembly and the cover pressing assembly and extends to the side of the cover pressing assembly opposite to the positioning assembly. The clamping member is connected to the end of the drive shaft near the cover pressing assembly and is used to press the cover pressing assembly against the positioning assembly under the drive of the drive shaft.

[0015] In some embodiments, the positioning component has a limiting portion on the side facing the cover pressing component, and the cover pressing component has a limiting mating portion on the side facing the positioning component. The limiting mating portion and the limiting portion are inserted into each other to position the cover pressing component relative to the positioning component.

[0016] In some embodiments, the machining clearance groove is used to allow a polishing wheel to pass through, so that the polishing wheel polishes the cutting edge of the workpiece.

[0017] The tool-machining fixture of this embodiment detachably covers the positioning component with a pressing assembly. A positioning space for positioning the workpiece exists between the pressing assembly and the positioning component, facilitating workpiece placement and accurate positioning. By providing a machining protrusion on the pressing assembly that communicates with the positioning space, when the tool-machining fixture clamps the positioned workpiece, the positioning component and the pressing assembly shield the unprocessed portion of the workpiece, allowing the workpiece's machining end to extend from the machining protrusion. This facilitates accurate machining of the workpiece's cutting edge and reduces the likelihood of over-machining of the coating at the cutting edge. A machining clearance groove is provided on the side of the pressing assembly away from the positioning component, allowing the polishing wheel to machine the cutting edge along the extension direction of the clearance groove, thus ensuring the consistency of the angle of the machined cutting edge. Therefore, the tool-machining fixture of this embodiment improves the accuracy of workpiece machining.

[0018] This application also provides a tool processing mechanism, including a robotic arm, a polishing wheel, and a tool processing fixture as described above, wherein the robotic arm is driven to be connected to the polishing wheel or the tool processing fixture.

[0019] The tool processing mechanism of this application improves the accuracy of workpiece processing by setting a tool processing fixture to clamp and position the workpiece. By connecting a robotic arm to a polishing wheel or tool processing fixture, the high movement accuracy of the robotic arm allows for more precise workpiece movement relative to the polishing wheel. Furthermore, the angle of the workpiece's cutting edge after processing is further guaranteed by the robotic arm's execution program, thereby further improving the accuracy of workpiece processing. This results in a smoother cutting edge contour, better consistency in contour appearance and sharpness, and effective protection of the coating at the cutting edge, thus increasing the cutting life of the workpiece's cutting edge. In addition, utilizing the high flexibility of the robotic arm, rough polishing, fine polishing, and finishing of the cutting edge and flank face can be achieved.

[0020] In some embodiments, the polishing wheel includes a first clamping member, a second clamping member, a connecting member, and a flexible polishing body. The flexible polishing body is detachably clamped between the first clamping member and the second clamping member. The connecting member passes through the flexible polishing body, and its two ends are respectively connected to the first clamping member and the second clamping member. Attached Figure Description

[0031] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between components; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0032] Please see Figure 1 This application provides a tool processing fixture 100 for clamping a workpiece 40 to be processed. The workpiece 40 can be a medical cutting tool, a machining tool, etc., and the processing of the workpiece 40 can include polishing, sharpening, etc. For ease of understanding, this application uses the example of a medical stapler cutting blade as the workpiece 40 and the processing of the workpiece 40 as polishing the cutting edge 411 to be processed. Obviously, this is not a limitation of this application.

[0033] Please see Figure 1 and Figure 2 In this embodiment, the tool processing fixture 100 includes a positioning component 10 and a cover component 20. The cover component 20 is detachably covered by the positioning component 10. A positioning space 14 is provided between the cover component 20 and the positioning component 10. The positioning space 14 is used to position the workpiece 40. The cover component 20 is provided with a processing avoidance groove 23 and a processing exposure opening 24. The processing avoidance groove 23 is provided on the side of the cover component 20 away from the positioning component 10. The processing exposure opening 24 passes through the cover component 20 and communicates with the processing avoidance groove 23. The processing exposure opening 24 is used to communicate with the positioning space 14 and is also used to allow the end 41 of the workpiece 40 to be processed to extend out.

[0034] Please refer to the following: Figure 5 and Figure 6 The tool processing fixture 100 can be mounted on the robotic arm 200, thereby enabling the tool processing fixture 100 to move relative to the polishing wheel 300. When processing the workpiece 40, the workpiece 40 is first positioned in the positioning space 14, with the end 41 of the workpiece 40 to be processed extending out of the processing opening 24; then the robotic arm 200 drives the tool processing fixture 100 to move along the processing path relative to the polishing wheel 300, and the polishing wheel 300 moves through the processing clearance groove 23 to the processing opening 24 to process the cutting edge 411 of the workpiece 40.

[0035] Because the positioning component 10 and the cover component 20 shield the unprocessed portion of the workpiece 40, the workpiece 40's unprocessed end 41 extends from the processing exposure opening 24, facilitating accurate processing of the workpiece 40's cutting edge 411 and reducing the likelihood of over-processing of the coating (not shown) at the cutting edge 4111 of the cutting edge 411. Furthermore, by providing the processing relief groove 23, the polishing wheel 300 can process the cutting edge 411 along the extension direction of the processing relief groove 23, thereby ensuring the consistency of the angle of the cutting edge 4111 after processing. Thus, the tool processing fixture 100 of this embodiment improves the accuracy of processing the workpiece 40.

[0036] The tool processing fixture 100 can be widely used in the surface treatment and edge sharpness machining processes of medical abdominal anastomosis cutting knives after sharpening. By introducing this tool processing fixture 100 and combining it with automated robotic arms, efficient interchangeable clamping of cutting knives can be achieved, effectively ensuring complex edge angles. This ensures that products in mass production achieve ideal and stable edge sharpness, high shape consistency, and quality stability. It can enhance the protection of the Teflon coating on the product surface, and the solution is applicable to all abdominal cutting knife edge polishing techniques.

[0037] In this embodiment, the coating at the cutting edge 4111 of the workpiece 40 is a Teflon coating, which improves biocompatibility and reduces friction and adhesion. In other embodiments, the coating at the cutting edge 4111 of the workpiece 40 may be made of other materials, and this application does not specifically limit this.

[0038] In this embodiment, the machining clearance groove 23 is used to allow the polishing wheel 300 to pass through, so that the polishing wheel 300 polishes the cutting edge 411 of the workpiece 40. Since the machining clearance groove 23 guides the polishing wheel 300 when polishing the cutting edge 411, it improves the angular consistency of the cutting edge 4111 of the workpiece 40 after polishing, and can prevent the coating at the cutting edge 4111 from being over-polished, thereby improving the accuracy of polishing the workpiece 40.

[0039] In this embodiment, the processing clearance groove 23 has a groove bottom wall 233, the groove bottom wall 233 has a first end 2331 and a second end 2332 opposite to each other, the processing exposure opening 24 is set corresponding to the first end 2331, and the groove bottom wall 233 is set inclined downward from the second end 2332 toward the first end 2331.

[0040] When the polishing wheel 300 processes the cutting edge 4111 of the workpiece 40's cutting edge 411 by passing through the processing relief groove 23, the polishing wheel 300 enters from the second end 2332 of the groove bottom wall 233 and processes the cutting edge 4111 of the cutting edge 411 at the processing exposure 24. By setting the groove bottom wall 233 of the processing relief groove 23 to be inclined downward from the second end 2332 toward the first end 2331, and the processing exposure 24 to be set corresponding to the first end 2331, the groove bottom wall 233 of the processing relief groove 23 guides the polishing wheel 300. After the polishing wheel 300 processes the cutting edge 4111 of the cutting edge 411, the angle is approximately the same as the inclination angle of the groove bottom wall 233, thereby improving the consistency of the angle of the cutting edge 4111 of the workpiece 40 after processing, and thus improving the accuracy of processing the workpiece 40.

[0041] Please refer to it again. Figure 1 and Figure 2 In this embodiment, the positioning component 10 includes a positioning element 11, and a cover assembly 20 is detachably mounted on the positioning element 11. The positioning element 11 has a positioning groove 111 on the side facing the cover assembly 20. The positioning groove 111 and the cover assembly 20 enclose a positioning space 14, and the machining protrusion 24 communicates with the positioning groove 111. The positioning groove 111 facilitates the placement of the positioning workpiece 40. By forming the positioning space 14 with the cover assembly 20, when the cover assembly 20 is mounted on the positioning element 11, it presses and limits the workpiece 40, thereby improving the accuracy of the tool machining fixture 100 in clamping the workpiece 40.

[0042] In this embodiment, the bottom of the positioning groove 111 is also provided with a positioning protrusion 1111, which is used to insert the positioning workpiece 40.

[0043] For example, the workpiece 40 is provided with an insertion hole 42. When the workpiece 40 is placed in the positioning groove 111, the positioning protrusion 1111 is inserted into the insertion hole 42 to position the workpiece 40.

[0044] Thus, by setting the positioning protrusion 1111 to be inserted into the positioning workpiece 40, the accuracy of positioning workpiece 40 by the positioning part 11 is improved.

[0045] Please refer to it again. Figure 1 and Figure 2In this embodiment, the positioning component 10 further includes a support member 12, which is located on the side of the positioning component 11 facing the cover component 20. The support member 12 has a support surface 121, which is disposed opposite to the processing exposure opening 24. The support surface 121 is used to support the part of the end to be processed 41 located in the processing exposure opening 24.

[0046] For example, the positioning member 11 has a mounting groove 112 on the side facing the cover assembly 20. The mounting groove 112 is located at one end of the positioning groove 111 and communicates with the positioning groove 111. The support member 12 is disposed in the mounting groove 112.

[0047] By providing a support surface 121 on the support member 12 to support the portion of the end 41 to be processed located in the processing protrusion 24, when the polishing wheel 300 processes the cutting edge 411 of the workpiece 40, the support member 12 supports the end 41 to be processed of the workpiece 40 and restricts the shaking of the end 41 to be processed of the workpiece 40, thereby improving the accuracy of the polishing wheel 300 in processing the cutting edge 411 of the workpiece 40. By setting the support member 12 and the positioning member 11 as separate structures, it is convenient to replace the support member 12 when it is damaged or when supporting different workpieces 40.

[0048] Please see Figure 2 In this embodiment, the support member 12 has a relief groove 122 on the side facing the cover assembly 20, and the relief groove 122 is located in the extension direction of the machining relief groove 23. Since the cutting edge 411 of the workpiece 40 is inclined, when the polishing wheel 300 polishes the cutting edge 411, the polishing wheel 300 is prone to contact with the support member 12, resulting in incomplete machining of the cutting edge 411. By setting the relief groove 122, and the relief groove 122 being located in the extension direction of the machining relief groove 23, when the polishing wheel 300 polishes the cutting edge 411, the relief groove 122 avoids the polishing wheel 300, so that the polishing wheel 300 can machine the entire cutting edge 4111 of the cutting edge 411, thereby improving the machining accuracy of the workpiece 40.

[0049] In this embodiment, the support member 12 is also provided with a limiting groove 123 on the side facing the cover assembly 20. The limiting groove 123 is located on the side of the avoidance groove 122. The limiting groove 123 is used to limit the structure of the end to be processed 41 away from the processing exposed opening 24.

[0050] For example, the workpiece 40 has a limiting protrusion 412 on the side of the end 41 to be processed away from the processing protrusion 24. When the support surface 121 supports the end 41 to be processed, the limiting groove 123 and the limiting protrusion 412 limit each other to restrict the movement of the end 41 to be processed.

[0051] Thus, by setting the limiting groove 123 to cooperate with the structure limiting end 41 to be processed away from the processing protrusion 24, the accuracy of the cutting edge 411 to be processed and the processing protrusion 24 being aligned is improved, thereby improving the accuracy of processing workpiece 40.

[0052] Please refer to it again. Figure 2 In this embodiment, the positioning component 10 has a limiting part 113 on the side facing the covering component 20, and the covering component 20 has a limiting mating part 212 on the side facing the positioning component 10. The limiting mating part 212 and the limiting part 113 are inserted and mated to position the covering component 20 relative to the positioning component 10.

[0053] For example, the limiting part 113 is a positioning pin inserted into the side of the positioning member 11 facing the cover pressing assembly 20, and the limiting mating part 212 is a positioning hole. The positioning pin and the positioning hole are engaged to position the cover pressing assembly 20 relative to the positioning member 10.

[0054] Thus, by setting a limiting part 113 and a limiting mating part 212 on the positioning component 10 and the cover pressing component 20 respectively, the position of the cover pressing component 20 relative to the positioning component 10 is positioned, thereby improving the accuracy of the cover pressing component 20 pressing on the positioning component 10.

[0055] In some other embodiments, the limiting part 113 may also be a positioning hole, and correspondingly, the limiting mating part 212 may be a positioning pin. This application embodiment does not specifically limit this.

[0056] Please refer to the following: Figure 2 , Figure 3 and Figure 4 In this embodiment, the portion of the cover pressure assembly 20 near the processing exposure 24 includes a wear-resistant structure 25, through which the processing exposure 24 passes. Since the polishing wheel 300 processes the workpiece 40's cutting edge 411 at high frequency while also processing the cover pressure assembly 20, the wear-resistant structure 25 is provided to withstand the high-frequency processing of the polishing wheel 300, thereby improving the service life of the cover pressure assembly 20.

[0057] In this embodiment, the wear-resistant structure 25 is made of ceramic material. In other embodiments, the wear-resistant structure 25 may also be made of other wear-resistant materials. This application does not specifically limit this embodiment.

[0058] Please refer to the reference again. Figure 2 , Figure 3 and Figure 4In this embodiment, the cover assembly 20 includes a cover member 21 and a guide member 22. The cover member 21 is detachably covered by the positioning member 11. The guide member 22 is located on the side of the cover member 21 facing the positioning member 11. The guide member 22 is a wear-resistant structure 25 and is disposed opposite to the support member 12. The machining clearance groove 23 includes a first sub-groove 231 and a second sub-groove 232 that are connected to each other. The first sub-groove 231 is located on the side of the cover member 21 away from the positioning member 11. The second sub-groove 232 is located on the guide member 22. The machining protrusion 24 penetrates the portion between the side of the guide member 22 facing the positioning member 11 and the bottom wall of the second sub-groove 232 away from the first sub-groove 231.

[0059] For example, the cover member 21 has an assembly groove 211 on the side facing the positioning member 11. The assembly groove 211 is arranged opposite to the mounting groove 112, and the guide member 22 is installed in the assembly groove 211.

[0060] By configuring the cover assembly 20, which includes a cover member 21 and a guide member 22, and the guide member 22 having a wear-resistant structure 25, it is easy to replace the guide member 22 when it is damaged. By setting the first sub-groove 231 and the second sub-groove 232 of the machining clearance groove 23 on the cover member 21 and the guide member 22 respectively, it is convenient to process the machining clearance groove 23. In addition, since the second sub-groove 232 is close to the machining exposed opening 24, the polishing wheel 300 has a longer dwell time when machining the cutting edge 411 of the workpiece 40, resulting in a longer contact time between the polishing wheel 300 and the second sub-groove 232. By setting the second sub-groove 232 on the guide member 22, it is beneficial to improve the service life of the machining clearance groove 23.

[0061] In this embodiment, the exposed opening 24 also penetrates the guide 22 and the cover 21 along the closing direction of the cover assembly 20.

[0062] In this embodiment, the cover pressure assembly 20 includes a cutting edge 221 located at the processing opening 24. The cutting edge 221 is arranged around the processing opening 24 and has an arc shape to conform to the shape of the cutting edge 411 to be processed on the workpiece 40. By setting the cutting edge 221, the polishing wheel 300 processes the cutting edge 411 to be processed on the workpiece 40 according to the shape of the cutting edge 221, thereby improving the consistency of the shape of the cutting edge 411 after processing, avoiding over-polishing, and thus improving the accuracy of processing the workpiece 40.

[0063] In this embodiment, when the tool processing fixture 100 positions the workpiece 40, the distance between the outer periphery of the cutting edge 411 to be processed on the workpiece 40 and the cutting surface 221 ranges from 0.08mm to 0.12mm, with a preferred value of 0.1mm. This design ensures that when the polishing wheel 300 processes the cutting edge 411 of the workpiece 40, the coating near the cutting edge 4111 is effectively protected, preventing over-polishing and reducing burr generation, thereby improving the accuracy of processing the workpiece 40.

[0064] In this embodiment, the guide member 22 has a pressing surface 222 on the side facing the support member 12. The pressing surface 222 is arranged opposite to the support surface 121. When the tool processing fixture 100 positions the workpiece 40, the pressing surface 222 presses the end 41 of the workpiece 40 to be processed onto the support surface 121. The pressing surface 222 and the support surface 121 are completely in contact with both sides of the end 41 of the workpiece 40 to be processed, thereby ensuring that the burrs at the cutting edge 4111 can be completely removed by the polishing wheel 300, avoiding the burrs from flipping over on both sides, and making the sharpness and consistency of the cutting edge 4111 higher.

[0065] Please refer to it again. Figure 1 and Figure 2 In this embodiment, the tool processing fixture 100 further includes a locking assembly 30. The locking assembly 30 includes a locking drive member 31 and a clamping member 32. The locking drive member 31 is disposed on the positioning assembly 10 and has a retractable drive shaft 311. The drive shaft 311 passes through the positioning assembly 10 and the cover assembly 20 and extends to the side of the cover assembly 20 opposite to the positioning assembly 10. The clamping member 32 is connected to the end of the drive shaft 311 near the cover assembly 20 and is used to press the cover assembly 20 against the positioning assembly 10 under the drive of the drive shaft 311. Thus, by providing the locking assembly 30, when the cover assembly 20 presses against the positioning assembly 10, the tool processing fixture 100 can automatically lock the cover assembly 20 and the positioning assembly 10, thereby improving the convenience and stability of clamping and positioning the workpiece 40 using the tool processing fixture 100.

[0066] Please refer to the following: Figure 3 , Figure 4 and Figure 5 In this embodiment, the positioning component 10 further includes a connecting seat 13, which is located on the side of the positioning member 11 away from the cover pressing component 20. The connecting seat 13 is used to connect with the robotic arm 200. The locking drive component 31 is located on the connecting seat 13. The positioning member 11 has a through hole 114, and the cover pressing component 21 has a stop groove 213 on the side away from the positioning member 11. The bottom of the stop groove 213 has an oblong hole 2131. The locking drive component 31 is a lifting and rotating cylinder. The clamping component 32 is perpendicularly connected to the drive shaft 311 of the locking drive component 31, and the size of the clamping component 32 is approximately the same as the size of the oblong hole 2131.

[0067] When the cover assembly 20 presses down on the positioning assembly 10, the clamping member 32 extends into the stop groove 213 through the oblong hole 2131. At this time, the locking drive member 31 drives the clamping member 32 to rotate by a preset angle, such as 90 degrees, through the drive shaft 311. Then, the locking drive member 31 drives the clamping member 32 to move towards the positioning assembly 10 through the drive shaft 311. The clamping member 32 presses the cover assembly 20 against the positioning assembly 10, thereby improving the convenience of locking the cover assembly 20 and the positioning assembly 10. After the cutting edge 411 of the workpiece 40 is processed, the locking drive member 31 drives the clamping member 32 to rotate and return to its original position through the drive shaft 311, thereby facilitating the removal of the cover assembly 20 from the positioning assembly 10.

[0068] In this embodiment, there are multiple positioning grooves 111, support members 12, guide members 22, machining clearance grooves 23, and machining exposure openings 24, each corresponding to one another. Thus, the tool machining fixture 100 can simultaneously clamp and position multiple workpieces 40, facilitating the simultaneous machining of the cutting edges 411 of multiple workpieces 40 by multiple polishing wheels 300, thereby improving the efficiency of machining workpieces 40.

[0069] In summary, the tool processing fixture 100 of this application embodiment detachably covers the positioning component 10 with the cover assembly 20, and a positioning space 14 for positioning the workpiece 40 is provided between the cover assembly 20 and the positioning component 10, which facilitates the placement and accurate positioning of the workpiece 40. By providing a processing exposure opening 24 on the cover assembly 20 that communicates with the positioning space 14, when the tool processing fixture 100 clamps and positions the workpiece 40, the positioning component 10 and the cover assembly 20 shield the parts of the workpiece 40 that do not need to be processed, and the end 41 of the workpiece 40 to be processed protrudes from the processing exposure opening 24, thereby facilitating accurate processing of the cutting edge 411 of the workpiece 40 and reducing the probability of over-processing of the coating at the cutting edge 4111 of the cutting edge 411. By providing a machining clearance groove 23 on the side of the cover assembly 20 away from the positioning assembly 10, the polishing wheel 300 can machine the cutting edge 411 to be machined along the extension direction of the machining clearance groove 23, thereby ensuring the consistency of the angle of the cutting edge 4111 of the cutting edge 411 after machining. In this way, the tool machining fixture 100 of this application embodiment improves the accuracy of machining the workpiece 40.

[0070] Please refer to the following: Figure 5 and Figure 6 This application also provides a tool processing mechanism 1000, including a robotic arm 200, a polishing wheel 300 and a tool processing fixture 100 as described above, wherein the robotic arm 200 is drivenly connected to the tool processing fixture 100.

[0071] The tool processing mechanism 1000 of this application improves the accuracy of processing the workpiece 40 by setting a tool processing fixture 100 to clamp and position the workpiece 40. By setting a robotic arm 200 and driving it to the tool processing fixture 100, the high movement accuracy of the robotic arm 200 makes the movement of the workpiece 40 relative to the polishing wheel 300 more accurate. Furthermore, the angle of the cutting edge 411 of the workpiece 40 after processing is further guaranteed by the execution program of the robotic arm 200, thereby further improving the accuracy of processing the workpiece 40. This makes the contour of the cutting edge 4111 of the workpiece 40 smoother, with better consistency in contour appearance and sharpness, and effectively protects the coating at the cutting edge 4111, thus improving the cutting life of the cutting edge 4111 of the workpiece 40. In addition, by utilizing the high flexibility of the robotic arm 200, rough polishing, fine polishing, and finishing of the cutting edge 4111 and the back face (not shown) can be achieved. Furthermore, since the robotic arm 200 can automatically perform compensated feed, it ensures that the processing line speed and processing point position remain unchanged during the batch processing of workpieces 40, and the processing parameters can be fixed, the processing pressure is constant, the processing line speed is constant, the movements are smooth and continuous, thereby further improving the accuracy of processing workpieces 40.

[0072] In some other embodiments, the robotic arm 200 may also be driven to connect with the polishing wheel 300. In this case, the robotic arm 200 can drive the polishing wheel 300 to move relative to the tool processing fixture 100, which can also accurately process the cutting edge 411 of the workpiece 40. This application does not specifically limit this aspect.

[0073] In this embodiment, the polishing wheel 300 includes a first clamping member 310, a second clamping member 320, a flexible polishing body 330, and a connecting member 340. The flexible polishing body 330 can be a cloth wheel. The flexible polishing body 330 is detachably clamped between the first clamping member 310 and the second clamping member 320. The connecting member 340 passes through the flexible polishing body 330, and its two ends are respectively connected to the first clamping member 310 and the second clamping member 320.

[0074] When machining workpiece 40, the flexible polishing body 330 contacts the cutting edge 411 of workpiece 40 for machining. By setting the first clamping member 310 and the second clamping member 320 to clamp the flexible polishing body 330 from both sides, the machining force and stability of the flexible polishing body 330 are ensured. In addition, when the flexible polishing body 330 wears out, the first clamping member 310 and the second clamping member 320 with different outer diameters can be replaced, so that the size of the flexible polishing body 330 exposed by the first clamping member 310 and the second clamping member 320 remains unchanged. In this way, the flexible polishing body 330 can continue to be used, thereby improving the utilization rate of the flexible polishing body 330 and saving costs.

[0075] In this embodiment, the tool processing mechanism 1000 also includes a water curtain cabinet (not shown), a waxing fixture (not shown), and a waxing robot (not shown). The robotic arm 200 is located in the water curtain cabinet, the waxing robot is located on one side of the water curtain cabinet, and the waxing fixture is located on the waxing robot.

[0076] Specifically, the waxing fixture is fixed to the waxing robot via a gripper (not shown in the figure), and the exposed length of the wax block (not shown in the figure) can be adjusted. The wax block length needs to be manually adjusted. After processing each workpiece 40, the waxing robot will automatically perform waxing compensation feed. When the wax block wears down to approximately 35mm, the waxing robot will give a signal, requiring timely adjustment of the wax block length. The tool processing fixture 100 effectively protects the workpiece 40 from over-polishing. The robotic arm 200 holds the tool processing fixture 100 according to the pre-programmed polishing trajectory to polish the workpiece 40. After processing each workpiece 40, the robotic arm 200 will automatically perform compensation feed. The water curtain cabinet ensures a humid processing environment, reduces dust generation, and makes the entire processing process more environmentally friendly.
