When the above-mentioned inner rising wedge bar slides horizontally, the slide block can be stretched out from the mounting seat in the vertical direction and pressed against the side inner wall of the leaf spring seat.

The internal expansion wedge is connected with the drive shaft of the first cylinder through the cylinder joint.

A pressing mechanism is also arranged on the bottom plate, and the pressing mechanism includes a pressing plate and a second air cylinder, and the second air cylinder pushes the pressing plate to press against the leaf spring seat.

Two sets of mounting seats and their clamping components are arranged side by side on the bottom plate. A through hole is arranged in the middle of the pressure plate, and a guide shaft and guide sleeve mechanism is arranged in the through hole. Pressure heads are arranged at both ends of the pressure plate, and the pressure heads are respectively against the two sides. on the spring seat.

Two second air cylinders are arranged on the outside of the pressing plate, and the drive shafts of the two second air cylinders abut against the two ends of the pressing plate respectively.

The outer end of the slider is connected with a pressing block.

The pressing block is provided with a tooth-shaped outer end surface.

The beneficial effects of the utility model are:

The utility model expands and tightens the side wall recessed at the bottom of the leaf spring seat through the clamping assembly, and uses the pressing mechanism to press the leaf spring seat on the mounting seat from the outside, thereby realizing the processing and clamping of the workpiece, which is convenient. Drill processing.
