Abstract
The invention provides a machining method of compound angles of a cross cutter. The machining method of the compound angles of the cross cutter comprises the following steps: on an ordinary lathe, a second angle value alpha is conveyed out through a small support plate; a forming lathe cutter is manufactured in a cutting mode, the angle of the forming lathe cutter is enabled to be the same as a first angle beta, and the forming lathe cutter is enabled to be perpendicular to a cutter frame; a workpiece is clamped, and cutter setting is carried out, and a surface A of the forming lathe cutter and an end surface of the workpiece are in the same line; longitudinal feeding of the forming lathe cutter is achieved by means of a middle support plate of the lathe, and the size value a in the position of the intersection point of the compound angles is met by controlling the feeding amount. By means of the technical scheme, error accumulation caused by multiple times of clamping and cutter setting is avoided, clamping at one time and machining of the compound angles at one time are achieved, machining efficiency is improved, and the occurrence of unqualified products is reduced, and the requirement of size precision in the position of the intersection point of the compound angles is completely met by controlling the feeding amount of the forming lathe cutter.
Description
Technical field
The present invention relates to a kind of processing method of cross cutter head compound angle, belong to mechanical processing technique field.
Background technology
In aviation field and other field of machining, often need to use various types of cutter head, as first-class in a word cutter head, cross-shaped knife, their application is all more extensive, but with regard to use performance with regard to the intensity after being connected, the performance of cross cutter head is better than other like products, but the processing of cross cutter head exists following technical barrier: 1. cross cutter head relates to the processing of compound angle, and the precision prescribed of two angles is higher; 2. have dimensional requirement in the point of intersection of compound angle, required precision is also higher, wayward.
Traditional processing technology is all first process the second angle, then calculates theoretical intersecting point place through technical staff with CAD, then processes the first angle from the second angle, makes the intersection point of two angles in theoretical point of intersection.Above-mentioned processing technology is adopted to need repeatedly to detect the size value of two angles, waste process time greatly, theoretical intersecting point can not be completely the same with the actual intersection point processed simultaneously, so that the size value of wayward point of intersection, finally cause the precise decreasing of product, percent defective is high.
Summary of the invention
The object of this invention is to provide a kind of processing method of cross cutter head compound angle, solve that cross cutter head compound angle is difficult to control, dimensional accuracy is difficult to meet the requirements of problem.
Technical scheme of the present invention: the processing method of cross cutter head compound angle, comprises following concrete steps:
(1) on engine lathe, the second angle value α is taken out of with little supporting plate;
(2) tailor shaped profile turning cutter, make the angle of shaped profile turning cutter identical with the first angle beta, and shaped profile turning cutter is placed perpendicular to knife rest;
(3) clamping workpiece, carries out tool setting, makes the end face of the A face of shaped profile turning cutter and workpiece on same straight line;
(4) utilizing the middle supporting plate of lathe to realize the length feed of shaped profile turning cutter, meeting the size value a of compound angle point of intersection by controlling the amount of feeding.
Beneficial effect of the present invention: employing the technical program avoids the error accumulation because multiple clamping, repeatedly tool setting cause, and achieves clamped one time, time processing goes out compound angle, improve working (machining) efficiency, decrease the appearance of waste product; The dimension precision requirement of compound angle point of intersection can be ensured completely by the length feed amount controlling shaped profile turning cutter; The technical program is practical, can promote the use of all this type of and have in the product of compound angle and go.

Fig. 1 is the structural representation of cross cutter head.
Fig. 2 is the structural representation of embodiment cross cutter head.
Fig. 3 is the structural representation of shaped profile turning cutter.
Detailed description of the invention
As shown in Figure 2, the processing method of cross cutter head compound angle, comprises following concrete steps:
(1) on engine lathe, the second angle value 26 ° 30 ' is taken out of with little supporting plate
0 -30 ';
(2) tailor shaped profile turning cutter, make angle and first angle 19 ° of shaped profile turning cutter
0 -30 'identical, and shaped profile turning cutter is placed perpendicular to knife rest, as shown in Figure 3;
(3) clamping workpiece, carries out tool setting, makes the end face of the A face of shaped profile turning cutter and workpiece on same straight line, now can't move little supporting plate, otherwise the first angle value and the second angle value all will change;
(4) utilizing the middle supporting plate of lathe to realize the length feed of shaped profile turning cutter, meeting the size value 3.84 of compound angle point of intersection by controlling the amount of feeding
0 -0.05.
Claims (1)
1. the processing method of cross cutter head compound angle, is characterized in that, comprises following concrete steps:
(1) on engine lathe, the second angle value α is taken out of with little supporting plate;
(2) tailor shaped profile turning cutter, make the angle of shaped profile turning cutter identical with the first angle beta, and shaped profile turning cutter is placed perpendicular to knife rest;
(3) clamping workpiece, carries out tool setting, makes the end face to knife face A face and workpiece of shaped profile turning cutter on same straight line;
(4) utilizing the middle supporting plate of lathe to realize the length feed of shaped profile turning cutter, meeting the size value a of compound angle point of intersection by controlling the amount of feeding.
