The invention discloses a combined fixture for processing automobile transmission gears, which comprises a clamping platform, a ring body is fixedly connected to the middle part of the upper end surface of the clamping platform, and a driving clamp is connected to the clamping platform inside the ring body through a shaft. A turntable, the drive turntable is provided with a drive groove, and the drive groove is connected with a top column through a shaft, and one end of the top column is fixedly connected with a positioning block, and the lower end surface of the clamping platform is connected with a centering screw, and the centering screw One end is connected with a centering rocker, and the other end of the centering screw is fixedly connected with a connection block, and the lower end of the connection shaft of the drive turntable is connected with a drive plate. The combined fixture for processing the gear of the automobile transmission can facilitate the self-centering clamping of the gear, so that the gear workpiece can be clamped quickly and accurately, and the gear can be switched and clamped in two directions, so that the inner ring of the gear or The outer ring is clamped and processed, and it is convenient to improve the stability of gear clamping, thereby improving the machining accuracy of the gear.
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...
