DETAILED DESCRIPTION

[0030] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0031] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] like Figures 1 to 8 As shown, the present application provides a clamping device for processing a metal plate, comprising a workbench 100 and a rectangular processing plate 110, wherein the processing plate 110 is located in the middle of the workbench 100, and further comprising a clamping assembly 200, wherein the clamping assembly 200 is used to position the processing plate 110 and can chamfer the processing plate 110;

[0034] The clamping assembly 200 includes a metal clamping seat 210, a bracket 220 and a moving rod 221;

[0035] The metal clamping seat 210 is fixed on the workbench 100 and is located at the corner of the processing plate 110. A reserved groove 211 is opened in the metal clamping seat 210, and a grinding block 212 is positioned in the reserved groove 211.

[0036] The grinding block 212 is an arc-shaped plate, and its inner arc surface contacts the corner of the processing plate 110. A metal plate 213 is fixed on the outer arc surface of the grinding block 212 away from the processing plate 110, and the free end of the metal plate 213 extends out of the reserved groove 211.

[0037] The bracket 220 is fixed on the metal clamping seat 210. A through slot 2201 is formed on the top of the bracket 220. The moving rod 221 extends into the through slot 2201 and is fixed to the metal plate 213.

[0038] There are four clamping assemblies 200 , and one clamping assembly 200 is located at a corner of the processing plate 110 to facilitate positioning of the processing plate 110 .

[0039] It is easy to understand that by repeatedly pulling the moving rod 221, the grinding block 212 is driven to move vertically at the corner of the processing plate 110, and the corner of the processing plate 110 is repeatedly ground, the processing plate 110 can be chamfered, and the processing plate 110 can be chamfered by utilizing the time of drilling the processing plate 110.

[0040] Specifically, if Figures 1 to 6 As shown, the movable length of the metal plate 213 is greater than the height of the processed plate 110 , that is, the processed plate 110 can be fully chamfered by moving the metal plate 213 .

[0041] Specifically, if Figures 1 to 6 As shown, a pull plate 222 is fixed to the free end of the moving rod 221, and the moving rod 221 can be conveniently moved by the pull plate 222. The moving rod 221 can move within the through groove 2201 within the range of 2mm to 3mm, that is, the grinding block 212 can grind an angle of about 45°, 2mm to 3mm.

[0042] Specifically, if Figures 1 to 7 As shown, coarse diamond particles are fixed to the middle of the inner arc surface of the grinding block 212, and fine diamond particles are fixed to the free end of the inner arc surface of the grinding block 212, and the coarse diamond particles and the fine diamond particles are parallel.

[0043] It is easy to understand that coarse diamond particles have a fast grinding speed and can chamfer the processed plate 110 faster, but coarse diamond particles are easy to grind out burrs, which can be removed by fine diamond particles, reducing the subsequent processing of chamfering.

[0044] In the above embodiment, the processing plate 110 is clamped from top to bottom between the metal clamping seats 210, and the processing plate 110 is positioned by using four metal clamping seats 210. The processing plate 110 is drilled by a drilling device, and at the same time, the moving rod 221 is repeatedly pulled to drive the grinding block 212 to move vertically at the corner of the processing plate 110. The corner of the processing plate 110 is repeatedly ground, which can achieve chamfering of the processing plate 110. The time for drilling the processing plate 110 is used to chamfer the processing plate 110, and there is no need to switch back and forth between the two processes, thereby saving processing time.

[0045] In some embodiments of the present application, Figures 1 to 6 As shown, the clamping assembly 200 further includes a pushing portion 230;

[0046] The pushing portion 230 includes a supporting plate 231;

[0047] The support plate 231 is fixed on the workbench 100, and a second through slot 2311 is formed on the support plate 231. A fixing frame 232 is fixed on one side of the support plate 231 away from the bracket 220.

[0048] The free end of the metal plate 213 passes through the second through slot 2311 and extends into the fixing frame 232;

[0049] Specifically, if Figures 3 to 8 As shown, a gas capsule 233 is fixed to the inner side of the fixing frame 232, and a material storage capsule 234 is fixed to the inner side of the gas capsule 233 close to the metal plate 213. The material storage capsule 234 is filled with magnetic powder, and the metal plate 213 and the magnetic powder repel each other magnetically.

[0050] In the above embodiment, the metal plate 213 can be limited by the set pushing portion 230, and the metal plate 213 can be pressed by the magnetic powder in the material storage capsule 234, thereby improving the grinding efficiency, so that the grinding block 212 can be pressed against the corner of the processing plate 110 for grinding. When the processing plate 110 is continuously ground and consumed by the grinding block 212, the grinding block 212 can always be pressed against the processing plate 110 for grinding under the balance of the mutual repulsive force between the material storage capsule 234 and the metal plate 213, thereby ensuring the stability of the grinding process.

[0051] Specifically, if Figures 1 to 7 As shown, a magnet block 214 is fixed on the metal clamping seat 210 , and the magnet block 214 contacts the surface of the processing plate 110 .

[0052] It is easy to understand that by adsorbing the magnet block 214 on the metal clamping seat 210 so that the magnet block 214 contacts the processing plate 110 , the clamping and fixing of the processing plate 110 can be further strengthened, thereby ensuring the stability of the processing of the processing plate 110 .

[0053] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
