Description

Wear-resistant polycrystalline diamond cutter

Technical Field

The utility model relates to a diamond cutter field especially relates to a wear-resisting polycrystalline diamond cutter.

Background

The existing diamond cutter has the characteristics of high hardness, high compressive strength, good heat conductivity, good wear resistance and the like, and can obtain high processing precision and processing efficiency in high-speed cutting, and the characteristics of the diamond cutter are determined by the state of diamond crystals. In the diamond crystal, four valence electrons of carbon atoms form bonds in a tetrahedral structure, each carbon atom forms a covalent bond with four adjacent atoms to form a diamond structure, and the bonding force and directionality of the structure are strong, so that the diamond has extremely high hardness.

However, when the tool bit at the end of the tool is damaged in the prior art, the whole tool needs to be replaced, which causes great waste to the manufacturing cost, and when the tool bit cannot freely change the tool shank in the stop process of the working gap, the machining dimension causes errors.

To solve the above problems, we propose a wear-resistant polycrystalline diamond cutter

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a wear-resisting polycrystalline diamond cutter aims at solving the technical problem among the prior art.

In order to realize the purpose, the utility model discloses a pair of wear-resisting polycrystalline diamond cutter, including tool bit and handle of a knife, the standing groove has been seted up to the tip of tool bit, set up threaded hole on the tool bit, threaded hole is provided with the bolt, the tool bit is provided with first connecting block in the one end of keeping away from the standing groove, first screw hole has been seted up on the first connecting block, the tip of handle of a knife is provided with the second connecting block, the second screw hole has been seted up on the second connecting block.

Wherein, the lower surface of the first connecting block is in close contact with the upper surface of the second connecting block.

Wherein, the bolt wears to establish the inner wall of standing groove and extends to the inside of standing groove.

The shape and the size of the first connecting block are matched with those of the second connecting block.

Wherein, the tip of first connecting block is the arc setting.

The utility model discloses a, set up the standing groove through the tip at the tool bit through this kind of wear-resisting polycrystalline diamond cutter, therefore, can directly place the blade inside the standing groove, then screw up the inner wall of blade and standing groove mutually through the bolt, realize the change of blade, avoided the tool bit to damage and the condition that will change whole cutter, and when needs change the blade, because the blade is fixed, and dismantle the size form error that can cause the machined part again if installed, at this moment, can make the connecting block rotate by the bolt between the elasticity connecting block, conveniently change the blade.
