Abstract

A tool for removing burrs from inner orifices, including a tool bar, a positioning sleeve, and a tool head. The middle part of the tool bar is provided with a positioning sleeve; the lower part of the tool bar is provided with a tool head. The length of the cutter head can be stretched. The utility model has the advantages of simple structure, convenient adjustment, clean deburring and no damage to other surfaces of workpieces. Depending on the shape of the workpiece, the head of the tool holder can be made into various forms. In addition, according to the size of the hole diameter of the workpiece, it is necessary to replace the positioning sleeve with different outer diameters and the same inner diameter, and the positioning sleeve is in clearance fit with the hole of the tool holder and the workpiece. When operating, first put the tool rod into a suitable positioning sleeve, then adjust the extension length of the tool head, put the tool rod into the hole of the workpiece, it is better not to touch the hole wall, and then move the center of the tool rod to the workpiece In the center of the hole, drop the positioning sleeve and turn the handwheel to remove the burrs of the inner hole. This tool is very beneficial for multi-specification and mass production.

Description

A cutting tool for deburring the inner orifice

technical field

The utility model relates to a tool for removing burrs from an inner orifice, which belongs to the technical field of mechanical processing tools.

Background technique

Existing workpieces, as shown in Figure 1, after machining, it is difficult to remove the burrs of the inner orifice. Drills, reamers, and scrapers are usually used to remove the burrs of the inner orifice, but the operation is difficult and the efficiency is low , the effect is not good, the burr removal is not clean, and it is easy to damage the surface of the inner hole. For this reason, we design a special tool to remove the burrs of the inner orifice. The structure is simple, the adjustment is convenient, the burrs are clean, and the other surfaces of the workpiece will not be damaged.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, thereby providing a special cutter for removing the burrs of the inner orifice, and a cutter for removing the burrs of the inner orifice.

A tool for removing burrs from inner orifices, including a tool bar, a positioning sleeve, and a tool head. The middle part of the tool bar is provided with a positioning sleeve; the lower part of the tool bar is provided with a tool head.

The length of the cutter head can be stretched.

The beneficial effect of adopting the above-mentioned technical scheme is:

The utility model has the advantages of simple structure, convenient adjustment, clean deburring and no damage to other surfaces of workpieces. Depending on the shape of the workpiece, the head of the tool holder can be made into various forms. In addition, according to the size of the hole diameter of the workpiece, it is necessary to replace the positioning sleeve with different outer diameters and the same inner diameter, and the positioning sleeve is in clearance fit with the hole of the tool holder and the workpiece. When operating, first put the tool rod into a suitable positioning sleeve, then adjust the extension length of the tool head, put the tool rod into the hole of the workpiece, it is better not to touch the hole wall, and then move the center of the tool rod to the workpiece In the center of the hole, drop the positioning sleeve and turn the handwheel to remove the burrs of the inner hole. This tool is very beneficial for multi-specification and mass production.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

A tool for removing burrs from inner orifices, comprising a tool bar 1, a positioning sleeve 2, and a tool head 4. The middle part of the tool bar 1 is provided with a positioning sleeve 2;

The length of the cutter head 4 can be stretched.

The utility model using method:

There are burrs 5 in the inner orifice of the workpiece 3, and the operation steps for removing the burrs 5 in the inner orifice are as follows: first, put the positioning sleeve 2 into the tool holder 1, put the cutter head 4 into the cutter holder 1, adjust the extension length of the cutter head 4, and place the cutter Put the rod 1 into the hole 3 of the workpiece. It is better not to touch the hole wall with the tip of the tool, then move the center of the tool rod 1 to the center of the workpiece hole, drop the positioning sleeve 2, pull it up with your hand and rotate the tool rod 1, and the The burrs 5 of the inner orifice are removed.
