The positioning assembly 30 comprises a positioning seat 31, a positioning ring 32 and a positioning pin 33, the positioning seat 31 is provided with a positioning groove 311 and two slide ways 312, the positioning ring 32 and the positioning pin 33 are both arranged in the positioning groove 311, concretely, the positioning ring 32 and the positioning pin 33 are both fixed in the positioning groove 311 through bolt locking, wherein the positioning pin 33 is perpendicular to the end surface of the positioning ring 32, the two slide ways 312 are symmetrically arranged about the axis of the positioning ring 32, the two slide ways 312 extend along the radial direction of the positioning ring 32, the two clamping jaws 41 of the clamping assembly 40 are movably arranged in the two slide ways 312, when the hydraulic assembly drives the clamping assembly 40 to act, the two clamping jaws 41 can freely move in the two slide ways 312, so that the two clamping jaws 41 can generate displacement in the axial direction and the radial direction of the positioning ring 32, and the displacement of the two clamping jaws 41 in the radial direction of the positioning ring 32 can enable the two clamping jaws 41 to abut against the positioning ring 32 The workpiece is clamped, and the displacement of the two clamping jaws 41 in the axial direction of the positioning ring 32 causes the two clamping jaws 41 to move the workpiece on the abutting positioning ring 32 in a direction approaching the positioning ring 32.

The inner wall of the positioning ring 32 is circular, the outer wall of the positioning ring 32 comprises two circular arc sections 321 and two linear sections 322, two notches 3111 are arranged on the side wall of the positioning groove 311, the positioning groove 311 is respectively communicated with the two slideways 312 through the two notches 3111, the two circular arc sections 321 are respectively attached to the inner wall of the positioning groove 311, the two linear sections 322 are respectively positioned on the two notches 3111, so that the two linear sections 322 are respectively opposite to the two slideways 312, in this way, when the two clamping jaws 41 are folded, the two clamping jaws 41 can be abutted against the two linear sections 322 of the positioning ring 32, so as to limit the movement of the clamping jaws 41 through the two linear sections 322 of the positioning ring 32, and because the positioning ring 32 is fixed in the positioning groove 311 through bolts, in this way, when the position of the movement limit of the two clamping jaws 41 needs to be adjusted, the retaining ring 32 needs to be replaced.

As shown in fig. 7 and 8, the positioning pin 33 includes a mounting section 331 and a positioning section 332, the mounting section 331 is cylindrical, the positioning pin 33 is fixed in the positioning recess 311 through the mounting section 331, a blind hole 333 is formed in a peripheral wall of the mounting section 331, the blind hole 333 is conical, the positioning seat 31 is provided with a threaded hole 313, the positioning pin 33 is inserted into the mounting hole at the bottom of the positioning recess 311, and the mounting hole is communicated with and perpendicular to the threaded hole 313, after the positioning pin 33 is inserted into the mounting hole at the bottom of the positioning recess 311, the blind hole 333 on the positioning pin 33 is opposite to the threaded hole 313, at this time, a screw is screwed into the threaded hole 313, so that the front end of the screw extends into the blind hole 333, the positioning pin 33 can be positioned and fixed, so that the positioning pin 33 is conveniently fixed, and the blind hole 333 is conical, the shape of the blind hole 333 is matched with the shape of the front end of the screw, so that the front end of the screw can extend into the blind hole 333 more deeply, and the positioning of the positioning pin 33 by the screw is firmer.

As shown in fig. 9, the clamping assembly 40 further includes two connecting posts 42, the two connecting posts 42 are respectively fixedly connected with the two clamping jaws 41, thus, the two connecting columns 42 can drive the two clamping jaws 41 to move synchronously when moving, the axes of the two connecting columns 42 form an acute included angle, when the hydraulic assembly drives the clamping assembly 40 to act, the two connecting columns 42 move along the respective axial directions, that is, one connecting column 42 moves along the direction a in the figure, and the other connecting column 42 moves along the direction B in the figure, so that when the two connecting columns 42 move, the two clamping jaws 41 are driven to be closed, at the same time, the two clamps 41 are driven to move in the direction close to the base 20, that is, the hydraulic assembly only needs to drive the two connecting columns 42 to move in the linear direction, the required action of the two jaws 41 is completed, so that the structure of the hydraulic assembly can be simplified.
