Technical Field
[0001] This utility model relates to the field of auxiliary structure technology for precision carving, and in particular to a positioning auxiliary device for chamfering parts. Background Technology
[0002] As the requirements for the precision of component processing gradually increase, precision engraving equipment is often needed to process components with intricate structures. However, when using a precision engraving machine to chamfer components such as silicon wafers, the sample is usually manually positioned before chamfering. This method lacks repeatability and a standardized positioning method, which can lead to sample position deviation, resulting in inconsistent quality after chamfering and affecting the roundness and edge integrity of the chamfer.
[0003] Therefore, there is an urgent need for a positioning auxiliary device for chamfering parts to solve the above-mentioned technical problems. Utility Model Content
[0004] The purpose of this invention is to provide a positioning auxiliary device for chamfering parts, which can be reused and can accurately position the parts, thereby improving the accuracy of the parts after chamfering.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A positioning auxiliary device for chamfering parts, used on the worktable of a precision engraving machine, includes:
[0007] The positioning platform can be installed on the workbench. The positioning platform has positioning holes, which are set to correspond to the processing position of the workbench. The positioning holes are used to install and position the workpiece to be processed.
[0008] A limiting component is disposed on one side of the positioning platform and is used to detachably connect to the worktable to limit the positioning platform to the worktable.
[0009] Optionally, a positioning protrusion is provided on one side of the positioning platform at the outer periphery of the positioning hole to assist the positioning hole in positioning.
[0010] Optionally, the inner diameter of the positioning protrusion gradually increases from the side closest to the positioning hole to the other side to form a guide angle, which is used to guide the installation of the workpiece.
[0011] Optionally, there is one positioning protrusion, which is arranged around the outer periphery of the positioning hole; or there are multiple positioning protrusions, which are evenly distributed along the outer periphery of the positioning hole.
[0012] Optionally, the limiting component includes at least two limiting parts, at least two of which are angled, and their angle is the same as the included angle between any two sides of the worktable that are angled, so that the limiting parts are connected to at least a portion of the sides of the worktable in a one-to-one correspondence.
[0013] Optionally, the aforementioned limiting part is provided with a magnetic suction component, which is used to magnetically engage with the aforementioned worktable.

[0033] The following reference Figures 1 to 5 This invention introduces a positioning auxiliary device for chamfering parts.
[0034] This embodiment provides a positioning auxiliary device for chamfering parts, which is used on the worktable 200 of a precision engraving machine to assist in chamfering parts.
[0035] Please refer to Figures 1 to 5 Specifically, the positioning auxiliary device for chamfering parts includes a positioning platform 10 and a limiting component 20. The positioning platform 10 can be installed on the worktable 200. The positioning platform 10 has a positioning hole 101, which is corresponding to the processing position 210 of the worktable 200. The positioning hole 101 is used to install and position the workpiece 300 to be processed. The limiting component 20 is disposed on one side of the positioning platform 10. The limiting component 20 is used to detachably connect to the worktable 200 to limit the positioning platform 10 on the worktable 200.
[0036] In this embodiment, the positioning auxiliary device for chamfering parts uses a limiting component 20 to mount the positioning platform 10 onto the worktable 200 of the engraving machine. After the positioning platform 10 is installed, the positioning holes 101 correspond to the processing positions 210 on the worktable 200. This allows the workpiece 300 to be directly positioned and installed through the positioning holes 101, avoiding misalignment caused by inaccurate positioning during installation. This improves the accuracy of the workpiece 300's position during installation, thereby increasing the precision of the workpiece 300 after processing. Furthermore, the limiting component 20 is detachably connected to the worktable 200, facilitating the installation and disassembly of the positioning auxiliary device without requiring structural modifications to the engraving machine, reducing manufacturing costs, and allowing for reuse.
[0037] Optionally, the cross-sectional area of the positioning hole 101 is the same as the cross-sectional area of the workpiece 300 to facilitate accurate positioning of the workpiece 300.
[0038] Optionally, the positioning platform 10 and the limiting component 20 are integrally formed, which simplifies the manufacturing process of the positioning auxiliary device for chamfering parts, reduces manufacturing costs, and improves the processing accuracy of the positioning adsorption column device.
[0039] Alternatively, the positioning aid for chamfering parts can be made of acrylic material, which meets certain strength and positioning requirements and is low in cost.
[0040] Please refer to Figures 3 to 5 In this embodiment, a positioning protrusion 11 is provided on one side of the positioning platform 10 at the outer periphery of the positioning hole 101 to assist the positioning hole 101 in positioning, thereby further improving the positioning effect of the workpiece 300 to be processed.
[0041] Optionally, a single positioning protrusion 11 may be provided, and the positioning protrusion 11 may be arranged around the outer periphery of the positioning hole 101; or multiple positioning protrusions 11 may be provided, and the multiple positioning protrusions 11 may be evenly distributed along the circumferential direction of the outer periphery of the positioning hole 101. Both of the above solutions can achieve the auxiliary function of further positioning and installation of the workpiece 300 to be processed.
[0042] Furthermore, the inner diameter of the positioning protrusion 11 gradually increases from the side closest to the positioning hole 101 to the other side to form a guide angle 12. The guide angle 12 is used to guide the installation of the workpiece 300, thereby realizing the guide space for the installation of the workpiece 300 and making it easier for the workpiece 300 to be installed on the positioning hole 101.
[0043] In an optional embodiment, the limiting component 20 includes at least two limiting parts 21, at least two of which are angled, and their angle is the same as the included angle between any two angled sides of the worktable 200, so that the limiting parts 21 correspond one-to-one with at least a portion of the side of the worktable 200. Because the limiting parts 21 correspond one-to-one with at least a portion of the side of the worktable 200, the positioning auxiliary device not only limits the positioning platform 10 in the vertical direction, but also limits it in the horizontal direction through at least two limiting parts 21. This achieves the function of the limiting component 20 in positioning and installing the positioning platform 10 on the worktable 200, and also improves the accuracy of the positioning platform 10 after installation.
[0044] Furthermore, the limiting part 21 is provided with a magnetic suction component, which is used to magnetically engage with the worktable 200. The setting of the magnetic suction component improves the stability of the connection between the limiting component 20 and the worktable 200, and is easy to disassemble without changing the structure of the engraving machine, thus reducing costs.
[0045] Specifically, the magnetic components and the worktable 200 have different magnetic properties to achieve a fixed connection between them.
[0046] In an optional embodiment, the limiting component 20 further includes a positioning part 22, which is disposed on the side of the positioning platform 10 facing the worktable 200. The positioning part 22 cooperates with the outer periphery of the processing position 210 of the worktable 200 to position the positioning platform 10. Through the cooperation between the positioning part 22 and the outer periphery of the processing position 210 of the worktable 200, precise installation of the positioning platform 10 can be achieved.
[0047] Optionally, the positioning part 22 is provided on the outer periphery of the machining position 210 of the worktable 200; or multiple positioning parts 22 are provided, and the multiple positioning parts 22 are evenly distributed circumferentially along the outer periphery of the machining position 210 of the worktable 200. Both of the above solutions can achieve the function of limiting the installation of the positioning part 22 and the worktable 200.
[0048] It should be noted that the positioning part 22 is mainly set to correspond to the processing position 210 of the worktable 200 being either protruding or recessed. It and the limiting part 21 can be set simultaneously or only one can be set. No specific limitation is made here.
[0049] For example, in this embodiment, three limiting parts 21 are provided. Two of the three limiting parts 21 are provided on one side of the positioning platform 10, and the other one is provided on the side of the positioning platform 10 adjacent to that side, with the two sides forming an angle. The limiting part 21 on the side with one limiting part is 120mm long, 10mm wide, and 20mm high; each of the two limiting parts 21 on the side is 80mm long, 10mm wide, and 20mm high.
[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
