Fixing and clamping mechanism for machining

The utility model discloses a fixed clamping mechanism for machining, which comprises a rack, a first clamping plate, a second clamping plate, an adjusting component, a movable supporting plate and an adjusting mechanism, and the rack is provided with a limiting hole matched with the movable supporting plate. According to the fixed clamping mechanism for machining, the telescopic shaft of the air cylinder is convenient for adjusting the movable supporting plate in the height direction, so that the relative distance between the movable supporting plate and the first clamping plate and the relative distance between the movable supporting plate and the second clamping plate are convenient to adjust, the operation of externally arranging a base plate when a workpiece is lifted is effectively avoided, and the working efficiency is improved. And the efficiency of workers is effectively ensured. 本实用新型公开了一种机械加工用固定装夹机构，包括机架、第一夹板、第二夹板、调节组件、活动托板以及调节机构，所述机架上设置有与所述活动托板相适配的限位孔。本实用新型一种机械加工用固定装夹机构气缸的伸缩轴便于对活动托板进行高度方向的调节，从而便于对
