Technical Field
[0001] The present application relates to the field of blade processing, and in particular to a blade grinding device. Background Art
[0002] A grinder is a device used to grind a metal sheet to form a sharp edge on the metal sheet.
[0003] In the prior art, a grinder generally includes a motor and a grinding wheel driven by the motor, and the motor drives the grinding wheel to rotate at high speed and grind the blade at high speed. A flat blade is generally grinded by a grinder, and a construction worker holds the grinder and grinds the unsharpened blade by the grinder to sharpen the blade.
[0004] When people use hand-held grinders to grind, it is not easy to control the grinding accuracy, which can easily cause unqualified products. Utility Model Content
[0005] In order to improve the stability of the use of the grinder and improve the accuracy of blade processing, the present application provides a blade grinding device.

[0007] By adopting the above technical solution, the first sliding rod is horizontally fixed on the support column, and the connecting block slides horizontally on the first sliding rod through the first sliding hole, thereby driving the grinder to slide in the horizontal direction, thereby facilitating the control of the grinding direction of the grinder, improving the accuracy of blade processing, and thereby improving the stability of the grinder.
[0008] Preferably, a second sliding rod is horizontally arranged between the two support columns, and a second sliding hole for the second sliding rod to pass through and slide is opened on the connecting block.

The support columns 2 are symmetrically arranged on the base 1, and the first sliding rod 3 and the second sliding rod 7 are both horizontally arranged between the support columns 2. The connecting block 4 is slidably connected to the first sliding rod 3 and the second sliding rod 7, and a first sliding hole 5 for the first sliding rod 3 to pass through and slide is provided on the connecting block 4, and a second sliding hole 8 for the second sliding rod 7 to pass through and slide is provided on the connecting block 4. The first sliding rod 3 is pressed against one end of the connecting block 4 in the first sliding hole 5, and the second sliding rod 7 is pressed against the other end of the connecting block 4 in the second sliding hole 8, thereby reducing the circumferential rotation of the connecting block 4. The grinder 6 is fixed to the connecting block 4 by bolts, and the handle 19 is provided on the grinder 6 to drive the grinder 6 to move. The mounting frame 18 is welded to a side of the base 1 close to the grinder 6 to mount the blade.
[0035] Reference Figure 1 and Figure 2 The support column 2 is slidably connected with a sliding block 11, and a sliding groove 12 is provided on the sliding block 11 for the support column 2 to pass through and slide. The support column 2 is pressed against the sliding block 11 in the sliding groove 12 so that the sliding block 11 slides along the height direction on the support column 2. The first sliding rod 3 and the second sliding rod 7 are both horizontally arranged between the two sliding blocks 11, thereby reducing the circumferential rotation of the sliding block 11 on the support column 2, and the grinding machine 6 can be moved along the height direction through the sliding block 11.
[0036] Reference Figure 1 and Figure 2, a pressing block 15 for pressing and fixing the first sliding rod 3 and the second sliding rod 7 is fixed by bolts on one side of the sliding block 11 close to the first sliding rod 3, and a first limiting groove 16 for limiting the first sliding rod 3 and the second sliding rod 7 is respectively provided on one side of the pressing block 15 close to the first sliding rod 3, and the first sliding rod 3 and the second sliding rod 7 are pressed against the pressing block 15 in the first sliding groove 12 to reduce the first sliding rod 3 and the second sliding rod 7 sliding on the pressing block 15. A second limiting groove 17 for limiting the first sliding rod 3 and the second sliding groove 12 is respectively provided on one side of the sliding block 11 close to the first sliding rod 3, and the first sliding groove 12 and the second sliding groove 12 are correspondingly provided, and the first sliding rod 3 and the second sliding rod 7 are pressed against the sliding block 11 in the second sliding groove 12 to reduce the first sliding rod 3 and the second sliding rod 7 sliding on the sliding block 11.
[0037] Reference Figure 1 and Figure 2 The first sliding block 11 is provided with a limit block 9, and the limit block 9 is provided with a penetration groove 10 for the first sliding rod 3 and the second sliding rod 7 to penetrate.
