Description
Technical field
The utility model relates to the tool-apron structure of a kind of milling machine, belong to the tool rest technical field of pavement milling machine.
Background technology
Pavement milling machine is a kind of maintenance of surface removing pavement disease and safeguard machinery, and it is to be installed on base body, by multiple tool rests, a kind of milling equipment of being welded on milling roller.The tool rest of milling machine is to support cutter head at work, simultaneously by severe crush, strong wear and impact, therefore the tool rest applying working condition of milling machine is extremely complex and severe, and this just requires that the tool rest of milling machine has the comprehensive mechanical performances such as higher wearability and obdurability simultaneously.
In prior art, tool rest owing to using in milling equipment needs when work is to ultimate value to change, but owing to the price comparison of tool rest is expensive, and replace difficulty, therefore need to configure the tool rest that the comprehensive mechanical performance such as wearability and obdurability is high in milling machine, the service life making tool rest is longer, reduces use cost and replacing and the time of repairing.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art to exist, and provides a kind of rational in infrastructure, easy to use, can improve the wearability of product, improves the knife holder mechanism of the milling machine in product service life.
The purpose of this utility model completes by following technical solution, a kind of knife holder mechanism of milling machine, it is mainly formed by a tool post that can be inserted into the internal and fixing tool rest handle of base body and anterior disjunctor, the outer side edges of described tool post leading section is provided with cylindrical head protruding forward, this cylindrical head front end face is provided with axially joins perforation for fix cutter head, the inner side edge of described tool post leading section is provided with supporting surface, described tool post leading section, all it is welded with one layer of wearing layer with broken alloy or alloyed powder heap including cylindrical head and supporting surface and side surrounding.
As preferably: the outside wall surface of described cylindrical head is provided with uniform annular groove, and is welded with one layer of wearing layer at the broken alloy of annular groove external or alloyed powder heap；The rearward end of described tool post, be positioned on the opposing end surface of cylindrical head be provided with oblique outer incline unload cutter groove；Described supporting surface is positioned at cylindrical head axially on the angle face less than 90.
As preferably: be provided with hole, location radially on the medial surface of described tool rest handle, and be provided with interior concane gap on this medial surface；An installation guide groove it is provided with on the lateral surface of described tool post；Described tool rest handle disjunctor is in the supporting surface opposed rear end portion of tool post.
This utility model has rational in infrastructure, easy to use, substantially increases the wearability of product, can make to improve the service life of product the feature such as 2-3 times.
