[0002] With the rapid development of the automobile industry, the processing and production of automobile parts has also developed accordingly. In processing enterprises, the end face of the automobile transmission housing after casting needs to undergo a series of processing operations such as milling, drilling positioning holes and mounting holes. These operations all require the transmission housing to be fixed and clamped before operation. The existing automobile transmission housing clamping devices are mostly operated by manual clamping, which is time-consuming and labor-intensive. If the operator is not careful, it may cause squeezing or collision injuries, which is not conducive to production and processing, and has low production efficiency.

[0003] The flipping jaw device in the prior art realizes the flipping processing of the automobile transmission housing through the combination of multiple groups of cylinders.

The flange structure, the cylinder extension block and the rotary clamping block mechanism cannot be used in the limited space inside the machine tool, and the flipping of the workpiece inside the machine tool cannot be realized.
