Abstract

The cross hole deburring cutter has the advantages that the contour of the cutter head is arc-shaped and is similar to the cross hole in shape, when the cutter head is used, the cutter head is downward along a straight hole, and when the cutter head reaches the position of the cross hole, the cutter head is gradually close to the cross hole, and the orifice deburring is removed by utilizing the consistency of the appearance of a cutting edge and the cross appearance, because the cutter head is provided with a rear angle, the deburring can be smoothly cut off, and after the deburring is cut off, the deburring is discharged along the direction of a chip groove. The utility model provides a cutter has solved the cross hole burr and has difficult the removal, extravagant cost of labor problem.

Description

Cross hole deburring cutter

Technical Field

The utility model relates to the field of machinery, in particular to a deburring tool for cross holes.

Background

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

In machining, cross holes can be frequently encountered, burrs of the cross holes are difficult to remove, particularly, some difficult-to-break chip materials are difficult to cut, and the burrs of the cross holes are more difficult to remove. In actual production, the burrs of the cross holes are generally manually removed after the machining is finished, and the removal efficiency is low. For some crossed holes with high precision, the hole wall is easily scratched when burrs are manually removed, so that the product is reworked or scrapped.

It should be noted that the foregoing description of the background art is only for the purpose of providing a clear and complete description of the technical solution of the present utility model and is presented for the convenience of understanding by those skilled in the art. The above-described solutions are not considered to be known to the person skilled in the art simply because they are set forth in the background of the utility model section.

Disclosure of Invention

The utility model aims to provide a deburring tool for cross holes.

In order to solve the technical problems, the utility model provides a deburring tool for cross holes, which comprises a tool bit, wherein the outline of the front part of the tool bit is arc-shaped, and a plurality of cutting edges are arranged on the tool bit.

Preferably, the cutting edges are arranged along the spiral direction, chip grooves are arranged between two adjacent cutting edges, and the chip grooves are spiral grooves.

Preferably, the cutting edge is provided with a relief angle of 6-9 °.

Preferably, the cutter further comprises a cutter bar and a cutter handle, and the cutter head is arranged at the end part of the cutter bar.

By the technical scheme, the utility model has the following beneficial effects:

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. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

It should be noted that, in the description of the present utility model, the terms "first," "second," and the like are used for descriptive purposes only and to distinguish between similar objects, and there is no order of preference between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.

As shown in the figure, the utility model provides a cross hole deburring tool, which also comprises a cutter bar, a cutter handle 3 and a tool bit 1 arranged at the end part of a guide rod 2, wherein the outline of the front part of the tool bit 1 is arc-shaped, and a plurality of cutting edges 11 are arranged on the tool bit 1. The chip blades 11 are arranged in a cutting mode along the spiral direction, chip grooves 12 are formed between two adjacent chip blades 11, and the chip grooves 12 are spiral grooves.

The whole outline of the tool bit 1 is arc-shaped and is similar to the shape of a cross hole, so that burrs are removed cleanly, and the problem that burrs are not removed cleanly due to dead angles formed by the shape of a tool and an intersection is avoided. The tool bit 1 is provided with a plurality of cutting edges 11, the cutting edges 11 are arranged in a spiral direction, the cutting edges are arranged in a cutting edge mode, when burrs are removed, cutting chips are stable, vibration is small, durability is good, cutting edge jumping at the crossing position can be prevented, and accordingly the service life of the tool is prolonged.

The cutting edge 11 is provided with a relief angle 13, and the angle of the relief angle 13 is 6-9 degrees, so that the cutter is sharper, and the cutter is beneficial to cutting burrs once. The spiral groove between the cutting edge 11 and the cutting edge 11 is beneficial to removing burrs according to the fixed direction, and the iron burrs are prevented from scraping the hole wall by iron cutting.

The contour of the cutter head 1 of the deburring cutter for the cross hole is arc-shaped, the shape of the cutter head is similar to that of the cross hole, when the deburring cutter is used, the cutter head is downwards along a straight hole, and when the cutter head reaches the position of the cross hole, the cutter head is gradually close to the cross hole, and the orifice burrs are removed by using the shape of the cutting edge 11 to be consistent with the shape of the cross hole, because the cutter head is provided with the rear angle 13, the burrs can be smoothly cut off, and after the burrs are cut off, the burrs are discharged along the direction of the chip removal groove 12. The utility model provides a cutter has solved the cross hole burr and has difficult the removal, extravagant cost of labor problem.

The above-described embodiments are merely preferred embodiments for fully explaining the present utility model, and the scope of the present utility model is not limited thereto. Equivalent substitutions and modifications will occur to those skilled in the art based on the present utility model, and are intended to be within the scope of the present utility model. The protection scope of the utility model is subject to the claims.
