[0028] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0029] Reference Figure 1 In the related art, the annular code disc is generally cut on a workbench, an inner diameter cutting groove 1 and an outer diameter cutting groove 2 are opened on the workbench, and the workbench is divided into a central part, a middle part and an outer edge part, and adsorption holes are set in these three parts. After cutting, the code disc adsorbed by the middle part is the required annular code disc. However, for narrow-edge code discs, it is difficult to open adsorption holes in the middle part that meet the adsorption force due to the small size of the middle part, thereby reducing the yield of the code disc.

[0030] It should be understood that the narrow side and wide side of the code disk are defined based on the difference between the inner diameter and the outer diameter of the code disk. That is, if the difference between the inner diameter and the outer diameter is too small, it means that the code disk has a narrow side. If the difference between the inner diameter and the outer diameter is large, the code disk has a wide side.

[0031] In the related art, for narrow-edge code discs, the middle part of the fixture is small in size, and it is difficult to open adsorption holes in the middle part that meet the adsorption force, which leads to a technical problem of reducing the yield of the code disc.

[0032] In order to solve the above technical problems, the present application proposes a code disc cutting jig, including a first cutting jig 100 and a second cutting jig 200. By using two independent cutting jigs, the inner diameter and outer diameter of the code disc can be cut respectively, thereby solving the technical problem of not being able to open adsorption holes in narrow areas.

[0033] The first cutting jig 100 and the second cutting jig 200 are detachably connected, so that the first cutting jig 100 can be matched with the second cutting jig 200, that is, the outer diameter of the code disc can be cut after the inner diameter is cut, avoiding the inability to cut the outer diameter of the code disc after the inner diameter is cut due to incompatibility. On the other hand, the first cutting jig 100 and the second cutting jig 200 can also cut the corresponding inner and outer diameters of the code disc separately.

[0034] The first cutting jig 100 includes a first plate portion 110, the first plate portion 110 is provided with a first cutting hole 120, a first support platform 130 is provided in the first cutting hole 120, and the first support platform 130 and the inner side of the first cutting hole 120 have a gap to form a first cutting groove 131, and the first support platform 130 is provided with a first support suction hole 132. It can be understood that a connecting piece is provided in the gap to connect the first support platform 130 and the first plate portion 110. The number of first cutting holes 120 can be one or more, depending on the actual situation.

[0035] The central part of the code disc is supported by the first support platform 130, and the inner diameter of the code disc is cut along the gap using a cutting tool or laser cutting method. At this time, the code disc adsorbed by the first support platform 130 is waste, and the outer code disc is used to be placed on the second cutting jig 200 for the next step of cutting.

[0036] The second cutting jig 200 includes a second plate portion 210, which is provided with a second cutting hole 220. A second support platform 230 is provided in the second cutting hole 220. There is a gap between the second support platform 230 and the inner side of the second cutting hole 220 to form a second cutting groove 231. A connecting piece is also provided in the gap to connect the second support platform 230 and the second plate portion 210. The number of second cutting holes 220 can be one or more, depending on the actual situation. The second support platform 230 is provided with a second support suction hole 232, and the cross-sectional diameter of the second support platform 230 is larger than the cross-sectional diameter of the first cutting hole 120.

[0037] In this way, the code disc cut by the first cutting jig 100 can be placed entirely on the second support platform 230 of the second cutting jig 200. The part extending out of the second support platform 230 is cut along the gap by the cutting tool. At this time, the code disc left on the second support platform 230 is an annular code disc.

[0038] In the embodiment of the present application, since the entire volume of the second support platform 230 is relatively large, the second support platform 230 has sufficient volume to facilitate the opening of the second support suction hole 232 on the second support platform 230, and after the hole is opened, the second support platform 230 can also have a higher stability to support the code disk.

[0039] In some embodiments, there are multiple first cutting holes 120 , which are not connected to each other; there are multiple second cutting holes 220 , which are arranged in one-to-one correspondence with the multiple first cutting holes 120 , and two adjacent second cutting holes 220 are connected.

[0040] See also Figure 2 In the embodiment of the present application, 16 first cutting holes 120 are provided, which are evenly divided into four columns and four rows. In this way, the user can place a whole large metal plate on the first plate portion 110, and the four corners of the first plate portion 110 need to be positioned. Similarly, positioning marks are also required at the four corners of the second plate portion 210. This ensures that the inner diameters of 16 code disks can be cut at the same time on the first cutting jig 100. Since the four corners of the second plate portion 210 are positioned, the four corners of the large metal plate can be aligned with the four positioning marks, and then the outer diameters of the 16 code disks can be cut, and finally 16 separate annular code disks are obtained.

[0041] It is understandable that the number of the first cutting holes 120 can also be set to 4, 6, 8, etc., which will not be further explained here.

[0042] The positioning mark may also be an "L"-shaped positioning boss.

[0043] Please continue reading Figure 2 The first plate portion 110 further defines a first auxiliary suction hole 140 , and the second plate portion 210 further defines a second auxiliary suction hole 240 .

[0044] The first auxiliary suction hole 140 is located outside the first support platform 130 and is used to absorb the large metal plate to be retained to ensure its stability during inner diameter cutting. The second auxiliary suction hole 240 is located outside the second support platform 230 and is used to absorb the outer ring of the large metal plate to ensure stability during outer diameter cutting.

[0045] It can be understood that the first supporting suction hole 132, the second supporting suction hole 232, the first auxiliary suction hole 140 and the second auxiliary suction hole 240 are all connected to the external vacuum adsorption equipment, that is, the first cutting jig 100 and the second cutting jig 200 need to be fixed on the vacuum adsorption equipment when in use, so bolt holes are opened on the first plate portion 110 and the second plate portion 210 to fix the first cutting jig 100 and the second cutting jig 200.

[0046] Please continue reading Figure 2 as well as Figure 3 The first support platform 130 defines a first cutting guide groove 133 , which is connected to the first cutting hole 120 . The second plate portion 210 defines a second cutting guide groove 233 , which is connected to the second cutting hole 220 .

[0047] The design of the cutting guide groove provides clear cutting path instructions for the cutting tool, ensuring the accuracy and stability of the cutting tool during the cutting process.

[0048] Guided by the guide groove, the cutting tool can cut more accurately along the predetermined path, avoiding cutting errors caused by improper operation or cutting deviation, thereby improving cutting accuracy and product quality.

[0049] On the other hand, the presence of the cutting guide groove simplifies the cutting process, allowing the cutting tool to enter and exit the cutting area more smoothly, reducing resistance and friction during the cutting process.

[0050] Please continue reading Figure 2 as well as Figure 3 In some embodiments, a plurality of first support suction holes 132 are provided, and the plurality of first support suction holes 132 are evenly distributed circumferentially around the axis of the first support platform 130 and are located at the edge of the first support platform 130; a plurality of second support suction holes 232 are provided, and the plurality of second support suction holes 232 are evenly distributed circumferentially around the axis of the second support platform 230 and are located at the edge of the second support platform 230.

[0051] The first supporting suction hole 132 and the second supporting suction hole 232 are evenly distributed around the axis, ensuring that the adsorbed object is subjected to balanced force in all directions, avoiding deviation or shaking caused by uneven force, thereby enhancing the adsorption stability. The uniform distribution of supporting suction holes helps to maintain the position accuracy of the cut material during the cutting process, making the cutting line more accurate and smooth.

[0052] Please continue reading Figure 2 as well as Figure 3 One of the first plate portion 110 and the second plate portion 210 is provided with a positioning column 300, and the other of the two is provided with a positioning groove 400. When the first cutting jig 100 and the second cutting jig 200 are connected, the positioning groove 400 is inserted into the positioning groove 400, and the first plate portion 110 and the second plate portion 210 are fitted together.

[0053] The coordination of the positioning posts 300 and the positioning slots 400 provides precise guidance and positioning for the connection between the first plate portion 110 and the second plate portion 210. This allows the first cutting jig 100 and the second cutting jig 200 to be matched together. The matched first cutting jig 100 and the second cutting jig 200 adhere to the same standards and specifications during design and manufacturing, ensuring a precise match between the two during connection and use. This also facilitates storage of the entire code disc cutting jig.
