Abstract
The utility model discloses a reamer with unequal guiding divisions, which belongs to the technical field of reamers and comprises a reamer body; the cutter head is connected with the cutter body, the cutting edges of the cutter head adopt guide angles of thirty degrees, and the cutting edges of the cutter head are arranged in an unequal manner, so that the service life of the reamer can be prevented from being reduced due to resonance, and the machining precision is further influenced; through setting up recess and radiating block, can improve the heat exchange area of reamer and air, through set up the radiating groove on the radiating block, can further improve heat radiating area to can improve the life of reamer.
Description
Technical Field
The utility model relates to the technical field of reamers, in particular to a reamer with guide unequal parts.
Background
A reamer is a rotating tool with one or more teeth to cut a thin layer of metal from the surface of a machined hole.
The service life of the existing reamer is not long, and size errors are easy to generate during hole finishing, so that the reamer with the guide unequal parts is provided.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a reamer with unequal guiding, which aims to solve the problems in the prior art.
In order to achieve the purpose, the utility model provides the following technical scheme: a reamer with unequal guiding comprises a reamer body; the cutting tool comprises a tool bit, the tool bit is connected with a tool body, the cutting edges of the tool bit adopt thirty-degree guide angles, and the cutting edges of the tool bit are arranged in an unequal manner.
As a preferable aspect of the reamer with unequal guiding directions of the present invention, wherein: the blade edge of the tool bit is four-edge.
As a preferable aspect of the reamer with unequal guiding directions of the present invention, wherein: the outer wall of the knife body is uniformly provided with grooves.
As a preferable aspect of the reamer with unequal guiding directions of the present invention, wherein: and the inner wall of the groove is uniformly provided with heat dissipation blocks.
As a preferable aspect of the reamer with unequal guiding directions of the present invention, wherein: radiating grooves are formed in the periphery of the radiating block.
As a preferable aspect of the reamer with unequal guiding directions of the present invention, wherein: the heat dissipation groove is of an arc-shaped structure.
Compared with the prior art, the utility model has the beneficial effects that: the guide angle is changed from 45 degrees to 30 degrees, so that the reamer can be more easily contacted with the inner wall of the bottom hole during processing, and the cutting edges of the cutter head are arranged in an unequal manner, so that the service life of the reamer can be prevented from being reduced due to resonance, and the processing precision is further influenced; through setting up recess and radiating block, can improve the heat exchange area of reamer and air, through set up the radiating groove on the radiating block, can further improve heat radiating area to can improve the life of reamer.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Referring to fig. 1 to 3, a reamer with unequal guiding comprises a reamer body 1; tool bit 2, tool bit 2 is connected with blade 1, and thirty degrees guide angle are adopted to the cutting edge of tool bit 2, like figure 1 and figure 3, through changing the guide angle into 30 by original 45, when adding man-hour more easily contact the bottom hole inner wall like this, the cutting edge of tool bit 2 is arranged unequally, and the cutting edge type of tool bit 2 is four-edged, arranges through making the cutting edge of tool bit 2 unequally, can prevent to cause the reduction of reamer life-span because of the resonance to influence the machining precision.
Example 2
Referring to fig. 4, recess 3 has evenly been seted up to the outer wall of blade 1, can increase the heat exchange area of blade 1 and air, and recess 3's inner wall evenly is provided with radiating block 4, and radiating block 4 is made through the copper-aluminum alloy, can further improve heat radiating area for the heat dissipation, radiating groove has all been seted up to radiating block 4's department all around, and the radiating groove is the arc structure, can further improve heat radiating area to can improve the life of reamer.
The rest of the structure was the same as in example 1.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
