The invention discloses a constant-pressure pneumatic clamp. The constant-pressure pneumatic clamp comprises a rack body, a pressing base is fixed to the top of the rack body, a rotating frame is connected to the middle of the rack body through a rotating shaft, a pressing head base is installed at the top end of the rotating frame, a pressing head in press fit with the upper surface of the pressing base is arranged at the bottom of the pressing head base, a pressure sensor abutting against the top of the pressing head is installed in the pressing head base, a cylinder is installed at the bottom of the rack body, a piston rod at the top end of the cylinder is connected with a rack, and the rack is engaged with a gear on the rotating shaft. The pressure sensor is integrated on the pressing head part to feed back the pressure of the pressing head to a plate, and therefore the pressure is controlled, and a good protection function is achieved on the plate; and a gear and rack transmission mechanism is adopted, larger rotating space is provided for the pressing head, when the clamp is not used, the whole structure of the clamp is kept below the surface of a conveying table top, conveying work of the surface of the conveying table top cannot be affected, meanwhile, the structure is simplified, and conveying of the plate cannot be hindered.
Description
technical field [0001] The invention relates to the field of fixtures, in particular to a constant pressure pneumatic fixture. Background technique [0002] In the sheet metal processing production line, the production line usually needs fixtures for the transportation and processing of the sheet metal, so as to ensure that the sheet material is always kept in the correct position during the transportation and processing process. In many cases, the thickness of the sheet to be processed is relatively thin. If the pressure of the fixture is too high, the sheet will be deformed. If the pressure of the fixture is too small, the relative position of the sheet will change during transportation and processing. In the current production line automatic clamps, the cylinder piston drives the moving guide rod four-bar mechanism to move, and the pressure head is fixed on the connecting rod, so as to realize the pressing and loosening of the sheet metal. But without the control of the ...
