The utility model relates to an adjustable angle type rotation hydraulic chuck, through the key-type connection between gyration axle and the clamp, perhaps the connecting screw who passes the clamp arranges in the gyration axle soon.
The utility model relates to an angularly adjustable type rotation hydraulic chuck, it is articulated mutually through joint bearing between adjusting cylinder's the piston rod and the connecting plate, joint bearing's one end is connected with adjusting cylinder's piston rod promptly, and joint bearing's the other end is articulated mutually through the round pin axle with the connecting plate.
The utility model relates to an angularly adjustable type rotation hydraulic chuck, the clamp is the half structure of embracing formula.
Compared with the prior art, the beneficial effects of the utility model are that:
the workpiece clamped by the upper clamping die and the lower clamping die can be conveniently driven to rotate by any angle through the convolution angle adjusting mechanism, so that frequent clamping is not needed, the operation efficiency is improved, and the operation precision is also improved; and reduces the need for special non-standard molds,
