Abstract

The invention discloses a holding device for a micro drill point grinder. The holding device comprises a seat body, a pair of holding parts and a power source, wherein the seat body forms an outer frame and a pair of support arms by integrally cutting a metal material block; the pair of support arms are parallelly arranged in the central part of the outer frame; a connecting part is arranged between each support arm and the outer frame; the holding parts are arranged on the end parts of the support arms and are normally butted; and the power source is provided with a abutting block and arranged between the support arms. The holding device has the characteristics that the pair of support arms are separated by the abutting block, so the pair of holding parts are separated to hold a micro drill point; and the micro drill point is fixed through the return elasticity of the pair of connecting parts and is ground, the stability of holding and fixing the micro drill point is greatly improved, and the grinding quality is improved.

Description

technical field [0001] The invention belongs to the field of micro-drill grinders, in particular to a clamping device for a micro-drill grinder which is used to clamp a micro-drill with a small diameter of 0.1 mm to 0.075 mm for secondary grinding. Background technique [0002] For some precision drilling, micro-drills are often used. This type of micro-drill is manufactured by grinding a high-speed steel that meets the requirements through a precision grinding device due to its small size and high length / diameter ratio. The precision grinding device must be equipped with a fixed frame clamp for firmly clamping the high-speed steel for grinding, especially for its cylindrical end that must be sharpened for drilling cutting purposes, and the grinding quality is also the same as that of the drill. hole stability, quality or efficiency. [0003] The holder clamp is generally in the open position when it is at rest. If you want to fix a micro-drill, you need to use an additiona...
