Abstract
The utility model discloses a special milling cutter for machining the flat surface chamfer of a roller, which comprises a cutter handle, wherein the end part of the cutter handle is detachably and fixedly provided with a cutter body, the front end of the cutter body is provided with an arc-shaped cutting edge, the arc radius of the cutting edge adopts any one specification of R10, R15, R20 or R25, the arc radius of the cutting edge is 0.5-1mm larger than the radius of the chamfer required by the flat surface of the roller, and the axial length dimension of the cutting edge is 3 mm.
Description
Technical Field
The utility model relates to the field of machining, in particular to a special milling cutter for machining flat surface chamfers of rollers.
Background
The roll is the indispensable part of rolling mill, and the middle part of roll is the reference axis, and both ends are usually for assembly and transmission effect, make the flat surface, and there is the chamfer in the flat surface of roll, for satisfying the customer to the flat surface outward appearance demand of roll, need carry out the chamfer to the flat surface of roll usually, and present chamfer does not have the instrument, is the manual work to carry out the chamfer usually, can't guarantee the chamfer size, causes the flat surface outward appearance of roll to be non-uniform, can't satisfy the customer demand.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide the special milling cutter for processing the flat surface chamfer of the roller, which has high processing efficiency and good processing appearance quality.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: the utility model provides a special milling cutter for processing flat chamfer of roll, includes the handle of a knife, the tip of handle of a knife can be dismantled fixedly and be provided with the cutter body, the front end of cutter body is provided with convex cutting edge, the circular arc radius of cutting edge adopts any kind of specification of R10, R15, R20 or R25, the circular arc radius of cutting edge is greater than the required chamfer radius of roll flat 0.5-1mm, the axial length size of cutting edge is 3 mm.
The technical scheme of the utility model is further improved as follows: the end part of the knife handle is detachably and fixedly connected with the knife body through threads.
Due to the adoption of the technical scheme, the utility model has the technical progress that:
the milling cutter is suitable for processing the flat surface chamfer of the roller, the processing of the flat surface chamfer of the roller is met by adjusting two key sizes, namely the arc size and the axial length size of a cutting edge of the cutter body, the milling cutter is driven by a machine tool to carry out chamfer processing on the flat surface of the roller, manual polishing is replaced, the processing efficiency is high, and the processing appearance quality is good.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic diagram of the operation of the present invention;
the roller comprises a roller body, a roller handle, a roller body, a cutter handle, a roller body, a cutter blade, a roller blade and a roller blade, wherein the roller body comprises 1, the roller handle, 2, the cutter body, 3, a cutting edge and 4.
Detailed Description
The present invention will be described in further detail with reference to the following examples:
as shown in fig. 1 to 2, the special milling cutter for machining the flat surface chamfer of the roller comprises a cutter handle 1, wherein a cutter body 2 is detachably and fixedly arranged at the end part of the cutter handle 1, preferably, the cutter body 2 is detachably and fixedly connected at the end part of the cutter handle 1 through threads. The front end of the cutter body 2 is provided with a circular arc-shaped cutting edge 3, the circular arc radius of the cutting edge 3 adopts any specification of R10, R15, R20 or R25, the circular arc radius of the cutting edge 3 is 0.5-1mm larger than the required chamfering radius of the flat surface 4 of the roller, and the axial length of the cutting edge 3 is 3 mm.
The specific use method comprises the following steps: according to the size of the required chamfer of the flat surface 4 of the roller, the arc radius of the cutting edge 3 is selected, the arc radius of the cutting edge 3 is ensured to be larger than the radius of the required chamfer of the flat surface 4 of the roller by 0.5-1mm, the flat surface and the excircle are prevented from being out of the platform due to over-cutting, then the cutter body 2 is connected with the cutter handle 1, the cutter handle 1 is connected with a transmission shaft of a machine tool, the machine tool is started, and the chamfer processing of the flat surface 4 of the roller is carried out. Satisfy the processing of 4 chamfers of roll flat surface through the adjustment of two critical dimension of 3 circular arc sizes of cutting edge and axial length size, the lathe drives milling cutter and carries out the chamfers processing to roll flat surface 4, replaces artifical manual polishing, and machining efficiency is high, and processing appearance quality is good.
