Abstract
A kind of milling machine cutter head, the cutter head that it is mainly carried out milling and plane operation by bottom for the handle of a knife installed and directly contact face, top forms, described cutter head is made up of hard alloy, anterior in cone tip shape head, bottom is provided with the anistree seat in abduction arc, and the bottom of cutter head is connected on the upper surface of Rotary-table body of tool bit by weld layer weldering, and described body of tool bit lower surface is connected to described cylindrical knife shank；It is provided with the groove for embedding bottom cutter head in the middle of the upper surface of described Rotary-table body of tool bit, and formation one is that fill a vacancy after welding with weld layer above after embedding groove bottom body of tool bit mutually neat with body of tool bit upper surface welds aspect；The bottom of described Rotary-table body of tool bit is provided with a circle and unloads cutter groove；Described handle of a knife and Rotary-table body of tool bit joint are configured with a packing ring being close to Rotary-table body of tool bit lower surface, and with the clasp of waveform interface on described handle of a knife；It has simple in construction, easy to install, and wear-resisting, intensity and fastness are good, and bottom alloy head, anistree design, adds the rotating property of cutter head, greatly reduce the breakage problem of cutter head alloy, can improve the features such as milling machine cutter head working life and efficiency.
Description
Technical field
The present invention relates to a kind of milling machine cutter head in municipal works, belong to milling machine technical field.
Background technology
The high speed development built along with highway in China, County Highway has obtained development at full speed especially the most in recent years,
Highway construction and maintenance department are more and more urgent to the demand of relevant plant equipment.Pavement milling machine is a kind of removal road surface
The maintenance of surface at broken position with safeguard machinery, be to be installed on base body, by multiple tool rests, the one that is welded on milling roller
Milling equipment.And milling machine cutter head is one of groundwork facility of milling machine, in the course of the work, the cutter head on milling machine with
The rolling of milling and planing drum, ground is carried out milling and plane operation.
In the prior art, conventional rigid alloy milling machine cutter head structure is made up of two parts, and a portion is for by closing
The milling machine handle of a knife that gold steel are made, another part is hard alloy head, and hard alloy head is welded on milling machine handle of a knife
Head.In practical work process, when milling machine cutter head runs into hardness higher cement concrete pavement, milling machine cutter head is subject to
Bigger shock loading and friction, traditional hard alloy milling machine tool bit abrasion is very fast, seriously reduces milling machine cutter head
Working life and efficiency；Even it is also easy to make cutter head alloy rupture.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, and a kind of simple in construction is provided, the side of installing and using
Just, wear-resisting, intensity and fastness are good, can improve the milling machine cutter head of milling machine cutter head working life and efficiency.
It is an object of the invention to complete by following technical solution, a kind of milling machine cutter head, it is mainly used by bottom
Carry out the cutter head composition of milling and plane operation in the handle of a knife installed and directly contact face, top, described cutter head is by hard alloy system
Becoming, anterior in cone tip shape head, bottom is that abduction arc anise is arranged, and the bottom of cutter head is connected in round platform by weld layer weldering
On the upper surface of body body of tool bit, described body of tool bit lower surface is connected to described cylindrical knife shank.
As preferably: be provided with in the middle of the upper surface of described Rotary-table body of tool bit for the groove of embedding bottom cutter head, and
Welds mutually neat with body of tool bit upper surface that is that fill a vacancy is formed after welding with weld layer above after embedding groove bottom body of tool bit
Aspect；The bottom of described Rotary-table body of tool bit is provided with a circle and unloads cutter groove；Described handle of a knife is joined with Rotary-table body of tool bit joint
It is equipped with a packing ring being close to Rotary-table body of tool bit lower surface, and with the clasp of waveform interface on described handle of a knife.
The present invention is a kind of improvement to prior art, and it has simple in construction, easy to install, wear-resisting, intensity and
Fastness is good, and bottom alloy head, anistree design, adds the rotating property of cutter head, and the fracture greatly reducing cutter head alloy is asked
Topic, can improve the features such as milling machine cutter head working life and efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, a kind of milling machine knife of the present invention
Head, the cutter head 2 that it is mainly carried out milling and plane operation by bottom for the handle of a knife 1 installed and directly contact face, top forms, described
Cutter head 1 be made up of hard alloy, anterior in cone tip shape head 3, bottom 4 is provided with the anistree seat in abduction arc, and cutter
The bottom 4 of 2 is connected on the upper surface of Rotary-table body of tool bit 6 by weld layer 5 weldering, and described body of tool bit 6 lower surface is connected to
Described cylindrical knife shank 1.
Shown in figure, it is provided with in the middle of the upper surface of described Rotary-table body of tool bit 6 for bottom cutter head 4 grooves embedded, and
Bottom cutter head 4 embed weld with weld layer 5 above after grooves after formation one that fill a vacancy mutually neat with body of tool bit 6 upper surface
Welding aspect；The bottom of described Rotary-table body of tool bit 6 is provided with a circle and unloads cutter groove 7；Described handle of a knife 1 and Rotary-table body of tool bit 6
Joint is configured with a packing ring 8 being close to Rotary-table body of tool bit 6 lower surface, and with waveform interface on described handle of a knife 1
Clasp 9.
The present invention is a kind of improvement to prior art, and it has simple in construction, easy to install, wear-resisting, intensity and
Fastness is good, and bottom alloy head, anistree design, adds the rotating property of cutter head, and the fracture greatly reducing cutter head alloy is asked
Topic, can improve the features such as milling machine cutter head working life and efficiency.
