[0026] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0027] like Figures 1-3 As shown, the positioning tooling suitable for the hydraulic chuck includes:

[0028] A chuck body 1, wherein the chuck body 1 is provided with a slide groove for moving a slider 4, the top of the slider 4 is fixedly connected to a clamping jaw 5, and one end of the clamping jaw 5 is fixedly connected to a stop block 6, and the other end of the clamping jaw 5 is rotatably connected to a pressure rod 7, and the pressure rod 7 is correspondingly arranged above the stop block 6;

[0029] The carrying plate 2 is fixedly connected to the surface of the chuck body 1 through a support 3. The carrying plate 2 is provided with an opening 9 for the movement of the stop block 6 and the pressure rod 7. A movable mechanism is provided on the surface of the carrying plate 2 located at the edge of the opening 9. The movable mechanism is transmission-connected to the push-pull mechanism through a connecting rod 14.

[0030] The edge of the chuck body 1 is provided with three evenly distributed slide grooves, each of which has a T-shaped cross-section, and each of which has a T-shaped cross-section. A slider 4 is provided inside the chuck. The clamping jaw 5 is located on the top surface of the chuck body 1, and a stop block 6 at one end of the clamping jaw 5 extends above the supporting plate 2.

[0031] In the present technical solution, the stable movement of the slider 4 is achieved by the opening of the slide groove, and the movement of the slider 4 is controlled by the rotary cylinder of the chuck body 1, so that the slider 4 can drive the clamping jaws 5 and the stop block 6 to move to clamp and position the workpiece, and the stop block 6 is located above the supporting plate 2, and can be fixed by pressing the edge of the workpiece by the stop block 6.

[0032] The number of the pressure rods 7 and the abutting blocks 6 is three. The pressure rods 7 are in a bent structure, and arc-shaped guiding grooves 8 are formed on both side walls of each pressure rod 7; the diameter of the bearing plate 2 is the same as that of the chuck body 1. The three openings 9 at the edge of the bearing plate 2 are correspondingly distributed with the pressure rods 7 and the abutting blocks 6, and the pressure rods 7 and the abutting blocks 6 are both slidably connected to the inside of the openings 9.

[0033] In this technical solution, after the workpiece is clamped by the abutting blocks 6, the rotation of the pressure rods 7 can drive them to press the edge of the workpiece, thereby completing the rapid fixation of the workpiece, ensuring the stable fixation of the workpiece, and improving the subsequent processing accuracy. After the clamping is completed, by the cooperation of the guiding grooves 8 and the connecting columns 11, when the connecting columns 11 slide inside the guiding grooves 8, the bent pressure rods 7 are driven to rotate downward, so that the ends of the pressure rods 7 press against the edge of the workpiece.

[0034] The moving mechanism includes moving blocks 10. The number of the moving blocks 10 is several. Every two moving blocks 10 are symmetrically distributed on both sides of the pressure rods 7, and a slot 13 is formed at the top of each moving block 10; the cross section of the moving block 10 is in a U-shaped structure. A connecting column 11 is fixedly connected to the side wall of the moving block 10, and the connecting column 11 extends into the guiding groove 8; a plurality of limiting plates 12 are fixedly connected to the top of the bearing plate 2. Every two limiting plates 12 are symmetrically distributed on both sides of the opening 9. The cross section of each limiting plate 12 is in a U-shaped structure, and each limiting plate 12 is fitted inside the slot 13 formed in the moving block 10; the bottom of the moving block 10 is rotatably connected to a connecting rod 14. The connecting rod 14 is in a U-shaped structure, and an abutting block 6 is arranged inside the connecting rod 14; the pushing and pulling mechanism includes a pull rod 16. The pull rod 16 is inserted through the middle of the chuck body 1. One end of the pull rod 16 is fixedly connected to the end head 15, the other end of the pull rod 16 is fixedly connected to a hydraulic cylinder, and the edge of the end head 15 is rotatably connected to three uniformly distributed connecting rods 14.

[0035] In this technical solution, when the pull rod 16 is pulled by the hydraulic cylinder, the pull rod 16 drives the connecting rod 14 on the end head 15 to move. The connecting rod 14 pulls the moving block 10 to move on the surface of the bearing plate 2. The stable movement of the moving block 10 is realized through the design of the limiting plates 12 and the slots 13. At this time, the moving block 10 drives the connecting column 11 to move inside the guiding groove 8, thereby realizing the rotation of the pressure rod 7.

[0036] Specifically, when the moving block 10 is kept stationary, the movement of the slider 4 will drive the pressure rods 7 to open. At this time, after the workpiece is placed and the slider 4 continues to move, the abutting blocks 6 are driven to abut against the workpiece, and then the pull rod 16 is pulled to move to realize fixation. When the workpiece is removed, first push the pull rod 16 to make the pressure rods 7 open. During the process of loosening the abutting blocks 6, slowly push the moving block 10 to move to ensure that the pressure rods 7 open in place, facilitating the smooth removal of the workpiece.
