Description

Technical Field

[0002] Flanges are parts that connect shafts to each other and are used to connect pipe ends. Flanges are also used on equipment inlets and outlets to connect two devices. Flanges need to be ground and polished during manufacturing. In order to prevent the flange from moving during the processing, a clamping mechanism is generally required to fix the flange. Although the clamping mechanism currently used can meet the fixing requirements for the flange, it still has defects in actual use.

[0003] For example, the patent publication number CN216542913U provides a clamping device for manufacturing flanges. The patent sets a mounting column, a flange body, a clamping spring, a sliding block, a top block, a fixture plate, a limit block, a sliding wheel and a connecting rod. The user sets the mounting column to facilitate the flange body to be sleeved on the mounting column. According to the size of the flange body, the user holds the connecting rod, the connecting rod drives the top block, the top block drives the sliding block, and finally drives the fixture plate to clamp the flange body, which plays a role of fast clamping speed and high efficiency, and achieves the effect of easy use.

When the inner diameter of the flange is large, it is not easy to fix the flange, the fixing effect is poor, and the scope of use is limited. Improvement is needed. Therefore, a clamping mechanism for manufacturing flanges is now proposed. Utility Model Content
