Description

Shockproof cutter for sawtooth-shaped machining ring groove

Technical Field

The utility model relates to the technical field of metal cutting tools, in particular to a shockproof tool for a zigzag machining annular groove.

Background

The IC cavity type part has a complex structure, a plurality of annular deep groove stations can not be normally processed to meet the drawing requirements, the efficiency is low, a cutter is easy to generate a cutter-shaking phenomenon by a conventional cutter, the cutter is unstable, the abnormality of a product is easy to cause, meanwhile, the consistency of the product is also uncontrollable, and the whole machine precision of the semiconductor equipment is directly influenced. Therefore, we propose a shockproof cutter for zigzag machining of ring grooves to solve the above problems.

Disclosure of Invention

The utility model aims to solve the defects that the conventional cutter in the prior art is easy to generate the cutter-shaking phenomenon, unstable and easy to cause the abnormality of products, meanwhile, the consistency of the products is also uncontrollable, and the whole accuracy of semiconductor equipment is directly affected.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides a shockproof cutter for a zigzag processing ring groove, which comprises a cutter handle and a cutter head detachably arranged on the cutter handle, wherein 3V-shaped notches which are vertically arranged are formed in the cutting edge of the cutter head, and V-shaped protrusions are arranged at the bottom end of the cutter head.

As a preferable technical scheme of the utility model, the cutter handle is provided with a mounting groove matched with the cutter head, and the cutter head is fixed in the mounting groove through a screw.

As a preferable technical scheme of the utility model, the opening included angle of the V-shaped notch is 60 degrees.

As a preferable embodiment of the present utility model, the angle of the V-shaped protrusion is 120 °.

As a preferable technical scheme of the utility model, the upper surface of the blade of the cutter head is provided with the chip removal groove which is arc-shaped, and the radius of the chip removal groove is 5mm.

As a preferable technical scheme of the utility model, the cutter head is made of hard alloy materials.

The beneficial effects of the utility model are as follows:

this device is through opening at the cutter blade has 3 60 degrees openings, thereby plays to reduce cutting force and reaches the shock attenuation effect, and the below has 120 degrees V type protruding better location effect that plays, cooperatees through cutter and software programming, realizes reducing artifical participation, improves machining efficiency, and then promotes the product quality.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-3, the shockproof cutter for the zigzag processing ring groove comprises a cutter handle 1 and a cutter head 2 detachably arranged on the cutter handle 1, wherein an installation groove matched with the cutter head 2 is formed in the cutter handle 1, the cutter head 2 is fixed in the installation groove through a screw, the cutter blade is convenient to replace quickly, and the positioning accuracy is 0.02mm;

the cutter head 2 is made of hard alloy materials, 3V-shaped notches 21 which are vertically arranged are formed in the cutting edge of the cutter head 2, the 3V-shaped notches 21 are transversely and linearly arranged and are uniformly distributed on the cutting edge of the cutter head 2, the included angle of the openings of the V-shaped notches 21 is 60 degrees, and the cutting force is reduced through the V-shaped notches 21, so that a damping effect is achieved;

the bottom end of the tool bit 2 is provided with a V-shaped bulge 22, the angle of the V-shaped bulge 22 is 120 degrees, and the stability of the tool bit on the tool handle 1 is improved through the V-shaped bulge 22.

Further, chip grooves 23 are formed in the upper surface of the cutting edge of the cutter head 2, the chip grooves 23 are arc-shaped, and the radius of the chip grooves 23 is 5mm.

In this embodiment, through opening 3V-arrangement openings 21 of 60 degrees at the blade of tool bit 2, thereby play the cutting force that reduces and reach the shock attenuation effect, the below has 120 degrees V-arrangement protruding 22 to play better location effect, improves machining efficiency, and then promotes the product quality.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
