AI Technical Summary
When producing irregularly shaped parts, existing aerospace composite material molds cannot maintain a horizontal position when the mold height changes, resulting in dimensional deviations in the irregularly shaped parts.
Design a leveling fixture for irregularly shaped parts. The fixture adjusts the height of the mold and keeps it level by means of a connecting rod and an angle adjustment mechanism. It includes a first base plate, a second base plate, a connecting rod, an angle adjustment mechanism and a clamping component. The horizontal adjustment of the mold is achieved by using the hinge structure of the connecting rod and the cooperation of the screw and nut.
