Embodiment Construction

[0019] The structure and specific operation of the present invention will be further described below in conjunction with the drawings and embodiments.

[0020] Such as figure 1 and figure 2 As shown, it shows the overall structure of the gun drill sharpening machine. The gun drill sharpening machine consists of three parts: a base part 1, a slide part 2, and a clamp part 3. The base part 1 is used to support and install the slide part 2 and clamp part 3. The slide table part 2 is equipped with the power devices required for sharpening such as motors and emery wheels. figure 1 The ability to move forward and backward in the X direction and move up and down in the Y direction is shown. The effect of fixture part 3 is to install and fix gun drill, and it has along Figure 4 The A-direction rotation and B-direction rotation capabilities are shown.

[0021] Such as image 3 As shown, it shows the structure of the clamp part 3, as can be seen from the figure, the clamp part ...

Abstract

The invention discloses a cutter grinding clamp used for a single-blade gun drill. The cutter grinding clamp used for the single-blade gun drill comprises a fan-shaped cone sleeve and a cylinder sleeve. The cone sleeve and the cylinder sleeve are connected mutually. Installing holes used for penetrating of the gun drill are formed in the center of the fan-shaped cone sleeve and the center of the cylinder sleeve. Locking screws are arranged on the fan-shaped cone sleeve and the cylinder sleeve. The locking screws are used for penetrating the sleeve wall in the direction perpendicular to the installing holes to fix the gun drill which penetrates through the installing holes. A locking face is arranged at the front portion of a cone. The cutter grinding clamp is suitable for being used in small-diameter single-blade gun drill with the diameter range of 1-3mm. the cutter grinding clamp is used for clamping the small-size single-blade gun drill. Meanwhile, when the cutter grinding clamp is used for cutter grinding of a cutter grinding machine, bending deflection cannot occur easily.

Description

technical field [0001] The invention relates to the field of jigs for machining, in particular to a sharpening jig suitable for sharpening single-edged gun drills. Background technique [0002] At present, the single-edged gun drill is a kind of tool used for deep hole processing. Due to long-term use, the cutting edge and cutter head will be worn out, and the gun drill sharpening machine is specially used to sharpen the cutting edge and the angle of the gun drill. Tool of. Existing gun drill sharpeners are mainly used for grinding gun drills with a diameter of 2-32mm. Its working principle is: fix the single-edged gun drill that needs to be ground in the fixture part, start the sharpening machine, determine the angle of the gun drill for grinding according to the processing requirements, move the sliding table part, and carry out grinding. [0003] If the clamped single-edged gun drill is less than 2mm, the fixture part is not easy to fix the gun drill, and there may also...
