Abstract
The utility model discloses a cutting tool for a milling rotor. The cutting tool comprises a tool apron; a toothed sleeve is arranged on the tool apron; a tool bit is arranged in the tool apron. The cutting tool for the milling rotor is used for overcoming the defects of taking time and needing great effort to replace an existing cutting tool. The cutting tool for the milling rotor is simple in structure and practical in functions; as the contact surface of the tool bit and the toothed sleeve is reduced, the frictional force is reduced, and therefore, the tool bit is quite convenient to replace.
Description
Technical field
The utility model belongs to milling cutter technical field, is specifically related to a kind of milling rotor cutter.
Background technology
Milling rotor is one of vitals of pavement milling machine, milling rotor for damaging road milling and become material slag so that redeck again after removing, the epitrochanterian cutter of milling is the parts on direct milling road surface, make this cutter in use easily in tooth cover, stop up more material slag because tooth cover is long, and because cutter head embeds tooth cover tension, therefore in the time that changing cutter head, needs extremely waste time and energy.
Utility model content
The purpose of this utility model is to provide a kind of milling rotor cutter, has solved the problem that existing cutter is wasted time and energy in the time need to changing.
The technical scheme that the utility model adopts is: a kind of milling rotor cutter, comprise tool rest, and on tool rest, be provided with tooth cover, in tooth cover, be provided with cutter head.
Feature of the present utility model is also,
Tool rest is arranged on tool rest cushion block.
Cutter head comprises connected point of a knife and shaft, and the direction of shaft along point of a knife to shaft has the tapering of 7 °～10 °.
The height that is shorter in length than tooth cover of shaft.
The beneficial effects of the utility model are: a kind of milling rotor of the present utility model has solved with cutter the shortcoming that replacing that existing cutter exists is wasted time and energy, a kind of milling rotor of the present utility model is simple with cutter structure, practical function, because cutter head and tooth cover contact surface diminishes, frictional force is reduced, therefore change cutter head very convenient.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of milling rotor cutter of the present utility model;
Fig. 2 is the structural representation of a kind of milling rotor of the present utility model cutter head in cutter.
In figure, 1. tool rest, 2. tooth cover, 3. cutter head, 4. tool rest cushion block, 31. points of a knife, 32. shafts.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is elaborated.
The structure of a kind of milling rotor cutter that the utility model provides as shown in Figure 1, comprises tool rest 1, is provided with tooth cover 2 on tool rest 1, in tooth cover 2, is provided with cutter head 3.
Tool rest 1 is arranged on tool rest cushion block 4.
As shown in Figure 2, cutter head 3 comprises connected point of a knife 31 and shaft 32, and shaft 32 has the tapering of 7 °～10 ° along point of a knife 31 to the direction of shaft 32.
The height that is shorter in length than tooth cover 2 of shaft 32.
A kind of milling rotor of the present utility model is inserted in tooth cover 2 with the shaft 32 of cutter, again tool rest cushion block 4 is welded on milling rotor, the cutter head 3 milling road surfaces of this cutter in the time that milling rotor rotates, choosing shaft 32 length is 4/5ths of tooth cover 2 height, in the time that cutter head 3 damages need to be changed, because overlapping the little therefore material slag of filling of 2 interior clearance spaces, also can reduce in tooth, the material slag that staff can overlap tooth 2 interior obstructions easily smashes and plucks out, and because shaft 32 has the tapering of 7 °～10 °, making cutter head 3 snap in the contact area that tooth overlaps 2 interior parts reduces, both frictional force is reduced, be unlikely to again to make because shaft 32 taperings are excessive cutter head 3 can not be stuck in securely in tooth cover 2, when staff after the material slag of having cleared up obstruction can pound out cutter head 3 tooth cover 2 very like a cork to change.
By the way, a kind of milling rotor of the present utility model has solved with cutter the shortcoming that replacing that existing cutter exists is wasted time and energy, a kind of milling rotor of the present utility model is simple with cutter structure, practical function, because cutter head and tooth cover contact surface diminishes, frictional force is reduced, therefore change cutter head very convenient.
