DETAILED DESCRIPTION OF THE INVENTION

[0014] The following further describes the specific implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0015] Embodiment:

[0016] A grinding device for chamfering the inner hole of a ceramic splitting tool includes a base 1, a drive motor mounting seat 2, a drive motor 3, a turntable mounting seat 4, a turntable 5, a belt 6, a positioning seat 7, a column 9, a grinding needle support 10, and a grinding needle 13;

[0017] The drive motor mounting seat 2 and the turntable mounting seat 4 are arranged on the base 1; the drive motor mounting seat 2 is provided with a drive motor 3; the turntable mounting seat 4 is provided with a turntable 5; the drive motor 3 drives the turntable 5 through the belt 6; the turntable 5 is provided with a positioning seat 7 for fixing the ceramic splitting tool A; the column 9 is arranged on the base 1, and the upper part of the column 9 is provided with a grinding needle support 10; the front end of the grinding needle support 10 is provided with a vertically downward grinding needle 13, and the lower end of the grinding needle 13 extends into the upper edge of the inner hole of the ceramic splitting tool A for grinding;

[0018] The column 9 is further provided with a pressure spring mounting seat 8, the upper front edge of the pressure spring mounting seat 8 is provided with a pressure spring 11, and the front end of the pressure spring 11 is provided with a positioning disk at the tip of the ceramic splitting tool 14; the positioning disk at the tip of the ceramic splitting tool 14 is provided with a small hole for the tip of the ceramic splitting tool A to pass through;

[0019] The lower front end of the pressure spring piece mounting seat 8 and the pressure spring piece 11 are connected by a nut and a bolt (not shown in the figure). Tightening the nut causes the pressure spring piece 11 to deform slightly downward, so that the tip positioning plate 14 of the ceramic splitting knife moves downward by a small distance. When processing ceramic splitting knives A with different lengths, through the deformation of the pressure spring piece 11, the tip of the ceramic splitting knife A can smoothly pass through the small hole on the tip positioning plate 14 of the ceramic splitting knife;

[0020] A knob 12 is provided on the tip positioning plate 14 of the ceramic splitting knife. The tip positioning plate 14 of the ceramic splitting knife is provided with a number of small holes with different diameters. By rotating the knob 12, the small holes with different diameters are rotated to the position where the tip of the ceramic splitting knife A is located, so as to adapt to the ceramic splitting knife A with different tip diameters.

[0021] Usage method: Install the ceramic splitting knife A on the positioning seat 7. By adjusting the pressure spring piece 11 and the knob 12, the tip of the ceramic splitting knife A can smoothly pass through the small hole of the tip positioning plate 14 of the ceramic splitting knife. The tip positioning plate 14 of the ceramic splitting knife forms support and protection for the tip of the ceramic splitting knife A; the lower end of the grinding needle 13 on the grinding needle support 10 is pointed and extends to the upper edge of the inner hole of the ceramic splitting knife A. The driving motor 3 drives the rotating table 5, and the rotating table 5 drives the ceramic splitting knife A to rotate horizontally through the positioning seat 7, so as to realize the grinding of the inner hole chamfer of the ceramic splitting knife A by the lower end of the grinding needle 13.

[0022] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
