Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a laser cutting jig for neodymium iron boron magnetic materials. Background Technique

[0002] Neodymium iron boron is composed of three elements: neodymium, iron, and boron. Neodymium iron boron has the advantages of high remanence density, high coercivity, and high magnetic energy product, and is currently widely used in electronic products, household appliances, etc. Currently, the jig structure for cutting sheet-shaped neodymium iron boron materials is as shown in the attached drawing (1). There is a stepped portion (14) about 1 mm on the jig for clamping and positioning the sheet (13). When performing laser cutting, it is necessary to avoid this stepped portion (14). Then, when cutting, at least 1.5 mm needs to be left at the edge position to prevent the laser head from cutting the stepped portion (14). That is, there will be an outer frame of the sheet (13) to be cut that cannot be cut and utilized, resulting in low overall utilization rate of the material, high production cost of the finished product. In addition, the middle of the current jig structure is a hollow structure, that is, the middle position of the sheet (13) is suspended. During the cutting process, for some sheets that have been partially cut but not completely cut in the whole sheet, due to the fact that there will be air blowing during laser cutting, some of the partially cut products will break away from the sheet (13), that is, the materials are scattered, resulting in the inability to continue the uncut parts of other parts, and the whole sheet will be wasted, causing waste of material resources, further increasing the production cost of the product. Moreover, this suspended support structure also needs to replace different jigs according to the thickness of different sheets for clamping the sheets, and the flexibility of jig use is insufficient. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a laser cutting jig for neodymium iron boron magnetic materials to solve the technical problems in the background technique.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions:

The second clamping table and the first clamping table are opposite in position, and the first X-axis driving member is drivingly connected to the second clamping table; the first clamping table includes a first base, a first tool rest, and a first support platform installed on the first tool rest. The first tool rest is fixed on one side of the first base above and close to the second clamping table; the second clamping table includes a second base, a second tool rest, and a second support platform installed on the second tool rest. The second tool rest is fixed in the direction of the first clamping table on the second base, and the second base is drivingly connected to the first X-axis driving member. The first support platform and the second support platform are spliced to form a cutting platform.

[0006] The first support platform is composed of an array of first blades. The first blades are vertically and perpendicularly fixed to one side of the first tool rest, and the array of first blades are fixed to the first tool rest side by side at equal intervals.

[0007] The second support platform is composed of an array of second blades. The second blades are vertically and perpendicularly fixed to one side of the second tool rest.

[0009] Compared with the prior art, for a laser cutting fixture for neodymium iron boron magnetic materials in this application, the cutting platform with a blade structure formed by two clamping platforms is used to support the sheet material. There is no need to reserve a 1.5-mm large margin at the edge of the sheet material. A margin of 0.2 - 0.5 mm can be reserved for cutting, effectively improving the utilization rate of the sheet material, greatly reducing the production cost of the product. At the same time, the cutting platform structure can also ensure that the sheet material will not fall outside the equipment due to being separated from the raw material during the cutting process, affecting the cutting quality of the sheet material and reducing the defective rate of product production.

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention.

[0016] Specific Embodiment 1: Please refer to Figures 2 to 5, in the embodiment of the present utility model, a laser cutting fixture for neodymium iron boron magnetic materials includes a first clamping table 9, a second clamping table 10, and a first X-axis driving member 11. The first clamping table 9 is fixed on one side of the edge of the blanking hole 101. The second clamping table 10 is opposite to the first clamping table 9 in position. The first X-axis driving member 11 is drivingly connected to the second clamping table 10. The first X-axis driving member 11 can adopt an existing linear module or a servo motor through a synchronous belt transmission method. In this application, the first X-axis driving member 11 adopts a motor through a synchronous belt transmission method to move the second clamping table 10 in the X-axis direction.

[0017] The first clamping table 9 includes a first base 901, a first tool rest 902, and a first support platform installed on the first tool rest 902. The first tool rest 902 is fixed on one side of the first base 901 above and close to the second clamping table 10. During actual installation and use, the first base 901 is fixedly connected to the machine table of the laser cutting machine. The second clamping table 10 includes a second base 1001, a second tool rest 1002, and a second support platform installed on the second tool rest 1002. The second tool rest 1002 is fixed in the direction of the first clamping table 9 on the second base 1001. The second base 1001 is drivingly connected to the first X-axis driving member 11. The first support platform and the second support platform are spliced to form a cutting platform.

[0018] The first support platform is composed of a group of first blades 903. The first blades 903 are vertically and perpendicularly fixed on one side of the first tool rest 902. A group of first blades 903 are fixed on the first tool rest 902 side by side and at equal intervals. In this application, nine groups of first blades 903 with the same structure are installed on the first tool rest 902. The cutting edge surface of the first blade 903 faces upward to support the sheet material 13.

[0019] The second support platform is composed of a group of second blades 1003. The second blades 1003 are vertically and perpendicularly fixed on one side of the second tool rest 1002. In this application, nine groups of second blades 1003 with the same structure are installed on the second tool rest 1002. The cutting edge surface of the second blade 1003 faces upward to support the sheet material 13. The first blades 903 and the second blades 1003 are staggered or in contact with each other to form a cutting platform for supporting the product. The cutting edges of the first blades 903 and the second blades 1003 are on the same horizontal plane.

[0020] In this application, the first blades 903 and the second blades 1003 are in contact with each other to form a cutting platform with a blade structure for supporting the sheet material 13. Compared with the staggered blade structure (see Figure 5 ), adopting the cutting table structure formed by direct contact in this embodiment can make the stroke of the second clamping table 10 shorter on the cutting platform with the same area, effectively saving the floor area of the equipment.

[0021] With the structure of the positioning fixture 8 of this embodiment, when the sheet material 13 is laser cut, there is no need to reserve a margin of greater than or equal to 1.5 mm at its edge position. A margin of 0.2 - 0.5 mm can be reserved for the cutting operation of the material. The blade structure is used to support the sheet material 13, making the support area of the sheet material 13 larger and more stable. Only a depth of 0.5 mm at the edge position of the sheet material 13 is required to squeeze the sheet material 13, and there is no need to replace different fixtures according to the sheet materials 13 of different thicknesses.

[0022] In this application, sliding plates 12 are respectively provided at the front and rear ends of the second base 1001. A first slider assembly is provided below the sliding plates 12. The sliding plates 12 can be slidably connected to the machine table of the laser cutting machine through the first slider assembly. By setting the structure of the sliding plates 12, the second clamping table 10 can slide more stably on the laser cutting machine and can achieve precise support and clamping of the sheet material 13.

[0023] Compared with the prior art, for a laser cutting fixture for neodymium iron boron magnetic materials in this application, the cutting platform with a blade structure formed by two clamping tables is used to support the sheet material. There is no need to reserve a large margin of 1.5 mm at the edge of the sheet material. A margin of 0.2 - 0.5 mm can be reserved for cutting, effectively improving the utilization rate of the sheet material and greatly reducing the production cost of the product. At the same time, the structure of this cutting platform can also ensure that the sheet material will not fall outside the equipment due to detachment from the raw material during the cutting process, which affects the cutting quality of the sheet material and reduces the defective rate of product production.
