By disassembling the clamp block, different types of clamps can be replaced, which is convenient for clamping castings of different shapes. There is no need to disassemble the clamp arm together, which reduces the cost of use.

The fixing plate 122 is placed, specifically, the bolt 233 is driven by the wrench to rotate counterclockwise, so that the extrusion block 232 enters the receiving groove 231 and moves away from the docking block 221, so that the fixation of the clamping block 123 can be released, and then the clamping block 123 can be pulled to be disassembled, and then the replaced clamping block 123 can be installed on the fixing plate 122. By disassembling the clamping block 123, different types of clamps can be replaced, which is convenient for clamping castings of different shapes.

An arc groove is provided on the side of the clamping block 123 away from the fixed plate 122. When the clamping arm 121 moves, the stabilizing frame 151 slides on the limiting protrusion 15, which can play a role of limiting and stabilizing, making the overall rigidity stronger.
[0034] A specific application of this embodiment is:
[0035] When in use, the clamping block 123 is docked with the fixing plate 122, and the docking block 221 will enter the docking groove 125, and the inserting block 234 will be plugged into the slot 223. When the fixing plate 122 contacts the clamping block 123, the bolt 233 is turned clockwise with a wrench to drive the extruding block 232 to enter the tapered groove 222 on the docking block 221.

When the casting needs to be clamped, the two hydraulic cylinders 131 are started at the same time, and the hydraulic cylinder 131 will drive the moving block 124 to move to the position of the fixed block 1. The bottom of the moving block 124 slides on the slide rail 242 through the slider 241, which can make the moving block 124 move more smoothly. At the same time, the moving block 124 will drive the clamping arm 121 to move together, and the clamping block 123 will follow the movement. At the same time, the stabilizing frame 151 on the clamping arm 121 slides on the limiting protrusion 15 , which can play a role in limiting and stabilizing, making the overall rigidity stronger. When the two clamping blocks 123 are in contact with the casting, the casting is clamped and fixed, and then it can be lifted by the pulley block 14. In the lifting process, since the plug-in block 234 is plugged into the slot 223 on the fixing plate 122, and multiple plug-in blocks 234 are provided, the gravity can be dispersed, the force on the clamping block 123 is reduced, and the clamping of a hundred-ton large piece can be more stable. At the same time, the provision of multiple plug-in blocks 234 can make the clamping block 123 more stable after installation. When it is necessary to When replacing the clamp block 123, use a wrench to rotate the bolt 233 counterclockwise to make the extrusion block 232 enter the storage groove 231 and move away from the docking block 221, so that the fixation of the clamp block 123 can be released, and then the clamp block 123 can be pulled to be removed, and then the replaced clamp block 123 can be installed on the fixed plate 122. By disassembling the clamp block 123, different types of clamps can be replaced, which is convenient for clamping castings of different shapes. There is no need to disassemble the clamp arm 121 together, which reduces the cost of use and makes the operation simpler and more convenient.
