Product.
The processing of existing some spur gears is typically all gear shape and tooth form separate machined, is passed through after gear blanking
The end face of gear shape, inner hole as benchmark and then reprocess tooth form.The precision between tooth form and inner hole, end face can thus be made
Error is amplified.
Summary of the invention
(1) technical problems to be solved
The technical problem to be solved in the present invention is to provide a kind of spur gear be from blank to product be processed and formed at one time, energy
Eliminate the spur gear numerical-control processing method of clamping precision error.
(2) technical solution
In order to solve the above technical problems, the present invention provides a kind of spur gear numerical-control processing method, include the following steps:
Step S01, clamping workpiece；Bar blank is clamped by the clamping device of numerically-controlled machine tool；
Step S02, rotational workpieces；The clamping device drives the bar blank rotation；
Step S03, sharp processing；Spur gear is processed by shape cutter, cutting tool, the inner hole knife tool of numerically-controlled machine tool
Shape, and do not cut gear blank；
Step S04, C-axis scale division positioning；It can be carried out indexing positioning by the C shaft work of digital control system, make to have processed straight
The bar blank of gear shape accurately stops at the initial position of first teeth portion；
For numerically-controlled machine tool, so-called C axis is exactly corresponding rotary motion about the z axis, can both realize main shaft any position
Control, and be able to achieve the linkage of X-C, Z-C.Any position of main shaft circumferential direction controls, and is exactly the concept of spindle index, cooperation lock
Angle position needed for workpiece is navigated to a processing by tight device.Application of the C axis on numerically-controlled machine tool is basically indexing
The application of positioning.
Step S05, tooth Profile Machining；Using toothed tool, cooperates Z axis to move back and forth by the X-axis of digital control system, process
The tooth form that quasi- off-position is set；
Step S06, C-axis scale division are positioned to next teeth portion；By the C s function of digital control system, accurately it is parked in next
The initial position of teeth portion；
Step S07, repeating said steps S05 and the step S06, until the entire form of gear tooth of the bar blank adds
Work is completed；
Step S08, cutting stock；Using cutting tool, the gear completed the process is cut from the bar blank
Workpiece；
Step S09, finished product deburring, sharp edge；Remove the burr of the gear workpieces cut down, sharp edge.
(3) beneficial effect
Workpiece product obtained by spur gear numerical-control processing method manufacture of the present invention can be eliminated in spur gear tooth Profile Machining
Trueness error problem caused by secondary positioning and clamping, workpiece product from finished product blanking is worked into all are added on numerically-controlled machine tool
What work was realized, secondary clamping processing is carried out without midway blanking, ensure that the machining accuracy of gear.
Detailed description of the invention
