On positioning disk described in technical scheme of the present invention can also be achieved in that, be provided with locating pad and alignment pin, positioning disk and bevel housing to be processed are by two alignment pins and two locating pads location.
Beneficial effect of the present invention is:
1, the present invention can accurately locate the dead eye of realizing double-ended boring machine boring bevel housing two ends after bevel housing, 4 workpiece pressings, thereby ensure the production requirement of bevel housing, improve the product quality of main gearbox assembly, correspondingly improved the service life of passenger vehicle drive axle and the security that passenger takes.
2, the present invention's bevel housing to be processed is by two alignment pins and positioning disk location, the end face of bevel housing contacts with locating pad, thereby realizes plane and two pits location, accurate positioning, positioning precision is high, thereby provides safeguard for the processing of bevel housing.
3, the present invention changes the processing that overall positioning disk above chuck body adapts to different product, has reduced the adjustment of alignment pin, locating pad, has effectively shortened frock and has changed the product cycle.The uniformity of the product processing promoting, labor strength lowers greatly, has effectively improved production efficiency.
4, bevel housing of the present invention and chuck body compress by four hydraulic press mechanisms, 4 even distribution type hydraulic compressions, it is firm to compress, effectively increase the rigidity that bevel housing adds man-hour, make bevel housing be difficult for man-hour deforming adding, thereby ensured the machining accuracy of bevel housing.
5, the present invention adopts hydraulic brace mechanism, after bevel housing machines, facilitates workman that bevel housing is left under order workpiece jack-up, has effectively avoided the workpiece that occurs while directly leaving bevel housing under order and " other strength " phenomenon of alignment pin 12.
6, the present invention is simple in structure, easy to use, effective, safe and reliable, is applicable to the boring processing of bevel housing dead eye in enormous quantities.
