Problems solved by technology

[0003] In production and processing, cam parts are often encountered. The processing procedures of cam parts are often complicated, and it is difficult to complete the processing in one sequence. Frequent clamping and calibration are required to meet the processing requirements. The zero point positioning device can just overcome this problem. This shortcoming can greatly improve the production and processing efficiency of the cam, but the zero point positioning plate has certain requirements on the size of the blank. For irregular parts such as cams, it is inconvenient to place the zero point positioning plate as a positioning clamp, and it is difficult to directly install it on the zero point positioning Processing on disk

Abstract

The invention relates to a connecting device for cam positioning. The connecting device is used for connecting a cam and a zero point positioning disc, and comprises a connecting disc, an intermediateshaft pin and a positioning pin, wherein the front surface of the connecting disc is provided with a central through hole, a positioning pin hole, a plurality of first threaded through holes and a plurality of second threaded through holes; a cam central hole is aligned with the central through hole and a cam positioning hole is aligned with the positioning pin hole when the cam is arranged on the front surface of the connecting disc; the intermediate shaft pin penetrates through the central through hole and the cam central hole and is in clearance fit with the central through hole and the cam central hole; the positioning pin penetrates through the cam positioning hole and the positioning pin hole and is in clearance fit with the cam positioning hole and the positioning pin hole; the first threaded through holes are arranged in an annular array around the central through hole, and are aligned with positioning through holes on the zero point positioning disc and are connected with thepositioning through holes through bolts; and the second threaded holes are used for mounting a clamp for fixing the cam on the connecting disc.

Description

technical field [0001] The invention relates to the field of cam processing and positioning, in particular to a connection device for cam positioning. Background technique [0002] Under the upsurge of intelligent manufacturing, the zero point positioning device occupies an important position, and even more and more people believe that the zero point positioning device is the basis of intelligent manufacturing. In the process of processing, the zero point positioning system is standardized in clamping and centralized in process. , There are many advantages in processing compound processing, which can greatly reduce the number of repeated clamping and machine tool calibration time for part processing, and improve production efficiency. [0003] In production and processing, cam parts are often encountered. The processing procedures of cam parts are often complicated, and it is difficult to complete the processing in one sequence. Frequent clamping and calibration are required...
