Relief angle adjustable device for automatic grinding of arc-edge diamond lathe tool

Abstract

The invention discloses a relief angle adjustable device for the automatic grinding of an arc-edge diamond lathe tool, comprising a base, wherein a driving device, a grinding disc and a photographing device are sequentially installed on the table board of the base; the driving device comprises a transverse feed device and a longitudinal feed working table connected with the transverse feed device; a longitudinal feed device is arranged on the longitudinal feed worktable; a swing device is connected with the longitudinal feed device; a relief angle adjustable fixture comprises a cantilever part connected with the swing device; the center of one side of an angle adjusting part and the center of the front end of the cantilever part are connected through a shaft and can rotate around the shaft at a certain rotation angle; the rotation angle can be displayed through a reading device; a lathe tool clamping part on which a groove is arranged is connected with one side of the angle adjusting part; and the diamond lathe tool arranged on a tool holder is inserted in and connected with the groove. By utilizing the device provided by the invention, the relief angle of the lathe tool can be accurately adjusted when the arc-edge diamond lathe tool is ground.

Description

technical field [0001] The invention relates to an automatic grinding device, in particular to an automatic grinding device for a circular arc edge diamond turning tool. Background technique [0002] In recent years, with the development of ultra-precision machining technology, the demand for aspheric and free-form surfaces of optical functional crystal materials with soft and brittle properties has gradually increased. Soft and brittle functional crystal materials have excellent optical, electrical and other physical properties, and have important application prospects in the fields of optics and energy. However, their anisotropy, soft and brittle, and deliquescence characteristics make them extremely difficult to process The machining requirements of precision, high surface integrity, and highly complex shapes make the existing ultra-precision machining technology face new challenges. At present, the method of ultra-precision turning using a single-crystal diamond turning...

Problems solved by technology

[0004] However, most of the grinding of single crystal diamond turning tools in the world is still done manually by skilled technicians, which is greatly affected by human subjective factors.

During the machining process, the confirmation of the edge shape accuracy of the cutting edge and the clearance angle of the tool is mainly carried out by off-line measurement of projectors, microscopes, and non-contact shape measuring devices, etc., due to the influence of human subjective fact
