Combined clamp for machining automobile transmission gear

Abstract

The invention discloses a combined clamp for machining an automobile transmission gear. The combined clamp comprises a clamping platform, a circular ring body is fixedly connected to the middle of the upper end face of the clamping platform, a driving rotating disc is connected to the portion, inside the circular ring body, of the clamping platform through a shaft, a driving groove is formed in the driving rotating disc, a jacking column is connected into the driving groove through a shaft, one end of the jacking column is fixedly connected with a positioning block, the lower end face of the clamping platform is connected with a centering screw rod, one end of the centering screw rod is connected with a centering rocking handle, the other end of the centering screw rod is fixedly connected with a connecting block, and the lower end of a connecting shaft of the driving rotating disc is connected with a driving plate. According to the combined clamp for machining the automobile transmission gear, self-centering clamping can be conveniently carried out on the gear, so that a gear workpiece can be rapidly and accurately clamped, bidirectional switching clamping can be conveniently carried out on the gear, so that clamping machining can be carried out on an inner ring or an outer ring of the gear, the clamping stability of the gear can be conveniently improved, and therefore, the machining precision of the gear is improved.

Description

technical field [0001] The invention relates to the technical field of combined fixtures, in particular to a combined fixture for machining automobile transmission gears. Background technique [0002] The combined fixture is a positioning fixture that is combined through various clamping and positioning structures to meet the needs of specific workpiece processing. In the process of automotive gearbox processing, high-precision processing of gearbox gears is required. Therefore, it is necessary to use Combined fixtures for automotive gearbox gear processing to meet the processing, clamping and positioning requirements of gears. [0003] However, the existing automotive gearbox gear processing uses ordinary fixtures to clamp the gear workpiece. The ordinary fixture is not convenient for self-centering clamping of the gear. When clamping, it is necessary to repeatedly determine the center position of the gear workpiece, and the operation is time-consuming. It is laborious, an...
