Claims

1. A combined clamp for core extraction, assembly, and handling of cylinder head sand cores, characterized in that, The system includes a crossbeam frame. A connecting plate is located on the upper center of the crossbeam frame for fixed connection to the connecting flange of the robot's end effector joint. The lower left half of the crossbeam frame is lower than the right half. Each half is equipped with a left movable gripper arm and a right fixed gripper arm. Parallel guide rails are installed front and rear on the lower left half, with movable slides installed at intervals on the guide rails. The left movable gripper arm includes a left arm frame, with a mounting bracket at the upper end of the left arm frame for fixed connection to the movable slides. The mounting bracket extends into the crossbeam frame and connects to a motor screw assembly located within the crossbeam frame. The right fixed gripper arm includes a right arm frame, with the upper end of the right arm frame fixed to the lower right half of the crossbeam frame. Near the right end, two parallel vertical guide columns are fixedly installed on the inner sides of the left and right booms. An upper slide and a lower slide are slidably connected to the guide columns. An upper clamping plate assembly and a lower clamping plate assembly are fixedly connected to the inner sides of the guide columns, respectively. The upper and lower clamping plate assemblies include connecting plates on the outer sides. The two connecting plates are fixedly connected to the push rod ends of the upper clamping cylinder and the lower clamping cylinder, respectively, which are located in the left and right booms. A base plate is installed at the lower end of the left and right booms. The base plate extends inward and a swing cylinder is installed on the extended section. The output shaft of the swing cylinder faces downward to the base plate and is fixedly connected to a hook assembly.

2. The combined core and molding fixture of claim 1, wherein: Both the upper clamping plate assembly and the lower clamping plate assembly include a fixing plate that connects the upper slide and the lower slide. The clamping plate is vertically connected to the inner side of the fixing plate, and the pressure pad is detachably fixed to the inner side of the clamping plate.

3. The combined core and molding fixture of claim 1, wherein: The mounting bracket includes a mounting plate, which is fixed to the upper end of the left boom. A floating cylinder is fixedly installed on the upper side of the mounting plate.

4. The combined core and molding fixture of claim 1, wherein: It includes an air passage plate, which is set on the upper left side surface of the crossbeam frame.

5. The combined core, molding and handling fixture of any of claims 1-4, wherein: The hook assembly includes a fixed base that is fixedly connected to the output shaft of the swing cylinder, and a hook is provided on the outside of the fixed base. The hook is composed of a baffle and an insert plate that are vertically connected.

6. The combined core and molding fixture of claim 5, wherein, The swing cylinder rotates at a 90-degree angle, making the hook perpendicular to or parallel to the crossbeam frame, respectively.
