Technical Field

[0001] The utility model relates to the field of cubic boron nitride tool production equipment, in particular to a blade grinding device used for PCBN tool production. Background Art

[0002] The Chinese name of PCBN is cubic boron nitride, which is a synthetic superhard material, often used to make cutting tools for cutting metals. Cutting tools made of cubic boron nitride are called cubic boron nitride cutting tools. The synthesis process of cubic boron nitride includes: mixed preparation, hot pressing and high-temperature sintering. After the synthesis of cubic boron nitride is completed, it needs to be sharpened to make a cutting tool. The cutting tool needs to be sharpened on two sides. The existing sharpening device needs to remove the tool after sharpening one side, change the direction, reinstall it and sharpen the other side, resulting in low efficiency. Therefore, it is particularly necessary to develop a sharpening device that can autonomously change the grinding surface of the tool and improve the efficiency of tool sharpening.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with specific embodiments. Figures 1 to 3 As shown:

[0020] Embodiment 1: A sharpening device for producing PCBN tools, comprising a base 1, a groove 2 is formed on the base 1, a driving mechanism 3 is arranged on the right side of the groove 2, the driving mechanism 3 is connected to a sharpening sheet 4 extending obliquely, and the driving mechanism 3 drives the sharpening sheet 4 to rotate.

[0021] A double-axis workbench is arranged on the left side of the groove 2, and a turntable 6 is rotatably arranged on the upper end surface of the double-axis workbench. The double-axis workbench controls the turntable 6 to move in the vertical and horizontal directions. Two clamping plates 11 are vertically arranged in the middle of the upper end surface of the turntable 6. Electric telescopic rods are horizontally arranged on the turntable 6 outside the clamping plates 11. The clamping plates 11 slide horizontally on the upper end surface of the turntable 6. The two electric telescopic rods control the two clamping plates 11 to move closer to or away from each other, so as to achieve the clamping or loosening of the tool by the two clamping plates 11.

[0022] When sharpening the tool, the two clamping plates 11 are used to clamp the tool, and the double-axis workbench is used to control the tool to approach the sharpening plate 4, and the sharpening plate 4 is used to sharpen the tool. After the sharpening of one side of the tool is completed, the turntable 6 rotates 180 degrees, and the double-axis workbench controls the tool to approach the sharpening plate 4, and the sharpening plate 4 is used to sharpen the other side of the tool.
