Abstract

The utility model discloses a milling cutter for processing a trapezoidal groove of a track roller fulcrum shaft of a bulldozer. The milling cutter comprises a cutter handle, and a cone-frustum-shaped cutting head which is formed at the front end of the cutter handle, wherein chip grooves are formed in the side of the cone-frustum-shaped cutting head; mounting surfaces for mounting milling cutter teeth are formed at the walls of the chip grooves; the milling cutter teeth are arranged on the mounting surfaces; and an included angle between a generatrix and an axis of the cone-frustum-shaped cutting head is 11-12 degrees. By virtue of the milling cutter, the processing procedures of the trapezoidal groove can be greatly simplified, and the processing efficiency of the trapezoidal groove is effectively improved.

Description

A kind of milling cutter for processing bull-dozer thrust wheel fulcrum dovetail groove
Technical field
The utility model relates to a kind of milling cutter, relates in particular to a kind of milling cutter for processing bull-dozer thrust wheel fulcrum dovetail groove.
Background technology
Processing for the dovetail groove on bull-dozer thrust wheel fulcrum, usually adopt plain cutter to carry out, plain cutter is comprised of handle of a knife and the cylindrical cutter head that is formed on the handle of a knife front end, the milling cutter tooth is set on cylindrical cutter head, the plain cutter processing dovetail groove of employing said structure need to carry out repeatedly milling just can be completed, working (machining) efficiency is low, can't meet the need of market.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provide a kind of simple in structure, working (machining) efficiency is high is used for the milling cutter of processing dovetail groove.
The purpose of this utility model realizes by following technical solution:
A kind of milling cutter for processing bull-dozer thrust wheel fulcrum dovetail groove, comprise handle of a knife, it is characterized in that: described handle of a knife front end is formed with the truncated cone cutter head, described truncated cone cutter head side is formed with chip area, the cell wall of described chip area is formed with for the installed surface that the milling cutter tooth is installed, the milling cutter tooth is installed on described installed surface, and the bus of described truncated cone cutter head and the angle between axis are 11-12 °.
Further, the described truncated cone cutter head described chip area of twice that is formed with circle distribution.
Further, described milling cutter tooth by bolt-locking on described installed surface.
Further, the end face diameter of described truncated cone cutter head is less than or equal to the minor face of processed dovetail groove.
Further, described installed surface is formed with the mounting groove suitable with the milling cutter tooth.
The utlity model has following beneficial effect:
Cutter head is set to truncated cone and the milling cutter tooth is installed on cutter head, can simplify the manufacturing procedure of isosceles trapezoid groove by the cutter head of truncated cone, the waist of the isosceles trapezoid groove of here processing and the bus that the angle between vertical line equals the truncated cone cutter head and the angle between axis, when the end face diameter of truncated cone cutter head equals the minor face of processed dovetail groove, the truncated cone cutter head can be realized once milling of dovetail groove, greatly simplify the manufacturing procedure of dovetail groove, effectively improved the working (machining) efficiency of dovetail groove; The truncated cone cutter head arranges the twice chip area, namely sets two milling cutters tooth on the truncated cone cutter head, can improve milling efficiency like this; The milling cutter tooth removably is locked on installed surface by bolt, can be convenient to like this disassembling, assembling and replacing of milling cutter tooth, reduces the inspection and maintenance cost; Installed surface is formed with the mounting groove suitable with the milling cutter tooth, can be convenient to the location of milling cutter tooth and prevent that milling cutter is because of loosening beat.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is front view of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the top view of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2 and shown in Figure 3, a kind of milling cutter for processing bull-dozer thrust wheel fulcrum dovetail groove comprises handle of a knife 1 and the truncated cone cutter head 2 that is formed at handle of a knife 1 front end.
Truncated cone cutter head 2 sides are formed with the twice chip area 3 of circle distribution, per pass chip area 3 is surrounded by cell wall 31,32,33, cell wall 31 and cell wall 32 extending axially along truncated cone cutter head 2, cell wall 32 is for being used for installing the installed surface of milling cutter tooth, installed surface is formed with the mounting groove 321 suitable with milling cutter tooth 4, mounting groove 321 bottom lands are formed with screw 21, milling cutter tooth 4 is arranged in mounting groove 321 and by the bolt-locking that coordinates with screw 21 and fixes, and the bus of truncated cone cutter head 2 and the angle between axis are 12 °.
Can realize that in order to make milling cutter the end face diameter of truncated cone cutter head 2 is arranged to equal the minor face of processed dovetail groove to once the milling of dovetail groove.
The above, it is only preferred embodiment of the present utility model, therefore can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
