The reference numbers are as follows: 1-knife handle, 2-knife, 3-chip groove, 4-cutting blade and 5-V groove.

Detailed Description

The technical solution of the present invention is clearly and completely described below with reference to the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and 2, a sponge damping plate drilling tool comprises a tool shank 1 and a cutter 2 which are fixedly connected coaxially, wherein the cutter 2 is a hollow shaft, a group of chip grooves 3 are symmetrically arranged on the side wall of the hollow shaft, the chip grooves 3 are parallel to the axis of the cutter 2, one end, away from the tool shank 1, of the cutter 2 is a cutting blade 4, the cutting blade 4 is an inner arc blade, the cutting blade 4 is uniformly divided into multiple segments, and a V-shaped groove 5 is formed between every two adjacent segments.

After the tool shank 1 is clamped by a drill chuck of a bench drilling machine, the sponge damping plate can be cut. The cutter 2 rotates at a high speed in the descending process, the V-shaped groove 5 is used for accommodating the sponge damping plate, the cutting blade 4 cuts the sponge damping plate, and the cut waste materials can enter the hollow part of the cutter 2 along the inner arc surface of the cutting blade and are discharged from the cutting discharge groove 3 step by step due to the fact that the cutting blade 4 is the inner arc blade.

In the embodiment, the inner diameter of the cutting knife 2 is 13mm, the outer diameter thereof is 16mm, and the knife handle 1 is a solid shaft, and the outer diameter thereof is 12 mm.

In the present embodiment, the cutting blade 4 is uniformly divided into six segments.

In the embodiment, the tool shank 1 and the cutting knife 2 are made of high-speed steel materials.

The drilling tool is designed aiming at the material characteristics of the sponge damping plate, the drilling efficiency is high, chip removal is smooth, the precision is high, cutting is complete, and damage to the sponge damping plate cannot be caused. In addition, the drilling tool is simple in structure, can be processed by utilizing leftover bits and pieces of residual shafts in a workshop, is extremely low in manufacturing cost, and is suitable for popularization and application.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
