Abstract
The invention relates to a process for machining a locking disc. The process is characterized by comprising the following steps of: making a blank; performing rough machining; hardening and tempering; performing semi finish machining, namely performing semi finish turning, and drilling and tapping; performing finish machining, namely performing end face grinding, finish turning and conical surface matched turning; and performing final inspection. By the process for machining the locking disc, a workpiece is clamped by a tool in the finish turning process and is not directly clamped on a lathe chuck, so that the phenomenon that the coloring of an inner conical surface is influenced because the workpiece is subjected to large deformation is avoided, and the machining quality of the inner conical surface is ensured.
Description
Technical field
The present invention relates to a kind of disk-like accessory processing technology, relate in particular to a kind of locking plate processing technology.
Background technology
Locking plate is a kind of transmission accessory, is used for the axle sleeve hoop in the axis body locking positioning, and locking plate is generally the annular disk structure; Be provided with internal conical surface, and through the expansion set that cooperates with its internal conical surface axle sleeve and axis body locked, expansion set is provided with the outer conical surface that is slidingly matched with the locking plate internal conical surface; For the quality of fit that guarantees locking plate and expansion set, make the isometrical distortion of expansion set everywhere and reduce frictional dissipation; And then make axle sleeve stressed even, and require locking plate internal conical surface crudy higher, stained area reaches more than 95%; The finish turning that is processed in of locking plate adds man-hour owing to be directly to be clamped in lathe at present; Be out of shape greatlyyer, make when joining Vehicle Processing the conical surface aberration, stained area does not reach requirement.
Therefore, need a kind of locking plate processing technology, make finish turning add direct clamping workpiece in man-hour, avoid workpiece to produce moderate finite deformation and to influence internal conical surface painted, guarantee the internal conical surface crudy.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of locking plate processing technology, its finish turning process is direct clamping workpiece, can prevent that workpiece from producing moderate finite deformation and to influence internal conical surface painted, guarantees the internal conical surface crudy.
Locking plate processing technology of the present invention comprises base, roughing, modified, semifinishing, fine finishining and inspection eventually, and said semifinishing comprises half finish turning and drilling and tapping; Said fine finishining comprises face grinding, finish turning and joins the car conical surface;
Specifically may further comprise the steps:
A. base: adopt and forge or the mode machining blanks of casting, forging rear annealing is handled;
B. roughing: rough turn machining blanks, monolateral reservation allowance 3～5mm, all roughness reaches Ra6.3;
C. modified: modified back hardness reaches HB240～302;
D. semifinishing:
D1. half finish turning, turning processing locking plate large end face, small end face, cylindrical and internal conical surface, monolateral reservation allowance 1～2mm, roughness reaches Ra3.2;
D2. drilling and tapping; Roughness reaches Ra6.3;
E. fine finishining:
E1. face grinding, the large end face polishing, flatness tolerance is not more than 0.02;
E2. finish turning, recruitment clamping are held workpiece turning processing and are removed large end face, small end face and cylindrical and reserve surplus, and roughness reaches Ra1.6;
E3. join the car conical surface, stained area is greater than 95%, and roughness reaches Ra1.6;
F. inspection eventually: detect overall dimension and fill in the size detection report, detected the back product warehousing.
Further, among the said step e, during finish turning 30 reconditionings of the every processing of frock once, frock two sides parallelism tolerance is not more than 0.03mm, adds to use man-hour cold oil to be lubricated and cool off.
The invention has the beneficial effects as follows: locking plate processing technology of the present invention; Its finish turning process adopts frock clamping workpiece; Workpiece directly is not held on lathe chuck, can prevent that workpiece from producing moderate finite deformation and to influence internal conical surface painted, guarantees the internal conical surface crudy.
