Of course, a plurality of mounting holes are generally reserved on the surface of the mounting base plate 1, and when the mounting position of each positioning seat is adjusted, the specific mounting position can be adjusted through different mounting holes.
Meanwhile, in order to facilitate each positioning seat to position and clamp the corresponding component on the workpiece, the positioning holes 9 are formed in each positioning seat, the positioning holes 9 are mainly used for being aligned with reserved holes formed in each component on the workpiece, and then positioning and mounting are carried out through fasteners such as bolts. The positioning holes 9 of each positioning seat are formed at different positions, which can be determined according to the shape of the corresponding component, and can be formed at the side, surface or bottom of each positioning seat.
In addition, in view of the heavy weight of the workpiece, in order to reduce the load and wear of the mounting baseplate 1, the present embodiment lays a layer of the load-bearing baseplate 8 on the surface of the mounting baseplate 1.
Meanwhile, in order to facilitate hoisting and transporting of the tool and the workpiece, the mounting base plate 1 is further provided with a lifting lug 10. Specifically, the lifting lug 10 can be arranged on the side wall of the installation base plate 1 and can be connected with a lifting hook, so that the lifting is convenient for a crane to lift.
