[0003] Patent No.: CN220278939U proposed a hydraulic locking flexible machining tooling fixture. Through a cylindrical clamping mechanism and a square column clamping mechanism, cylindrical workpieces and square column workpieces can be clamped and fixed at the same time. Only by driving a connecting rod to rotate through a servo motor can the switching between the cylindrical clamping mechanism and the square column clamping mechanism be realized, and the use is more flexible and convenient.

[0004] However, during the use of this device, when machining workpieces with different shapes, it is necessary for the staff to rotate the motor to adjust the device before it can be used to clamp another workpiece with a different shape. Moreover, the clamping device fixes the workpiece through multiple groups of hydraulic telescopic rods, resulting in a cumbersome clamping process and high production costs. Therefore, a tooling hydraulic locking device is proposed to solve the above problems. Summary of the Utility Model

[0011] Preferably, a spring is fixedly connected to the inner wall of the chute, and one end of the spring away from the chute is fixedly connected to the sliding rod.

[0012] Preferably, a collection box is fixedly connected to the bottom of the base, a shaking plate is slidably connected to the inside of the collection box, and the shaking plate is arranged obliquely.

Detailed implementation manners

[0023] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The function of the accompanying drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a tooling hydraulic locking device, including a base 1, a fixing frame 3 is fixedly connected to the surface of the base 1, a processing device 4 is arranged at one end of the fixing frame 3 away from the base 1, a groove 6 is opened on the surface of the base 1, a placing plate 15 is fixedly connected to the inner wall of the groove 6, and the placing plate 15 is arranged in a conical shape. A hydraulic telescopic rod 9 is fixedly connected to the inside of the base 1. The output end of the hydraulic telescopic rod 9 is slidably connected to the inside of the base 1. The output end of the hydraulic telescopic rod 9 is fixedly connected to a clamping block 7. A first limiting groove 8 is opened on the surface of the clamping block 7. The bottom surface of the clamping block 7 is slidably connected to the surface of the placing plate 15, and the first limiting groove 8 is arranged in an arc shape.

[0025] When the device fixes a square workpiece, place the square workpiece on the surface of the placing plate 15, and then start the hydraulic telescopic rod 9. The output end of the hydraulic telescopic rod 9 pushes the clamping block 7, so that the clamping block 7 slides to fix and clamp the square workpiece. And when processing a cylindrical workpiece, place the cylindrical workpiece into the first limiting groove 8, and then the staff starts the hydraulic telescopic rod 9. The output end of the hydraulic telescopic rod 9 pushes the clamping block 7 to move, and clamps and fixes the cylindrical workpiece placed in the first limiting groove 8. Furthermore, the device can clamp and fix cylindrical workpieces and square workpieces, reducing the usage limitations of the device. At the same time, it avoids setting multiple hydraulic telescopic rods 9 and avoids replacing the clamping device by rotating the motor, reducing the manufacturing cost of the device.

[0026] A second limiting groove 13 is opened on the surface of the clamping block 7, and the specification of the second limiting groove 13 is slightly smaller than that of the first limiting groove 8. When clamping a smaller cylindrical workpiece, the cylindrical workpiece can be placed on the surface of the placing plate 15, and by moving the clamping block 7, the second limiting groove 13 is brought into contact with the cylindrical workpiece to clamp and fix the workpiece.

[0027] The surface of the clamping block 7 is fixedly connected with a connecting rod 10, and the connecting rod 10 is set in a J shape. The surface of the connecting rod 10 is slidably connected with the surface of the placing plate 15. A chute 11 is opened in the inner wall of the base 1, and a sliding rod 14 is slidably connected to the inner wall of the chute 11. One end of the sliding rod 14 away from the chute 11 is fixedly connected with an impact rod 16. A fixing rod 17 is fixedly connected to the surface of the impact rod 16, and the fixing rod 17 is set in a serrated shape. The surface of the connecting rod 10 is slidably connected with the surface of the fixing rod 17. A spring 12 is fixedly connected to the inner wall of the chute 11, and one end of the spring 12 away from the chute 11 is fixedly connected with the sliding rod 14.

[0028] After the workpiece is processed, the hydraulic telescopic rod 9 drives the clamping block 7 to move. The clamping block 7 drives the connecting rod 10 to move. The movement of the connecting rod 10 squeezes the surface of the fixing rod 17. Further, the fixing rod 17 drives the impact rod 16 and the sliding rod 14 to move. The movement of the sliding rod 14 squeezes the spring 12. Under the elastic force of the spring 12, the spring 12 pushes the sliding rod 14. The sliding of the sliding rod 14 drives the impact rod 16 and the fixing rod 17 to move, so that the impact rod 16 continuously moves up and down.

[0029] When processing the workpiece, since the placing plate 15 is set in a conical shape, the chips generated by the processing will slide down from the inclined surface of the placing plate 15. Further, the chips will fall downward through the gap between the placing plate 15 and the groove 6.

[0030] The bottom of the base 1 is fixedly connected with a collection box 2. A shaking plate 18 is slidably connected inside the collection box 2, and the shaking plate 18 is arranged in an inclined shape. A through groove 5 is opened on the surface of the collection box 2, and the through groove 5 is also arranged in an inclined shape. A spring 12 is also arranged inside the collection box 2, and the spring 12 is fixedly connected with the shaking plate 18.

[0031] When the chips slide down from the surface of the placing plate 15, they will fall into the inside of the collection box 2. Since both the shaking plate 18 and the through groove 5 are arranged in an inclined shape, and at the same time, when replacing the workpiece, the impact rod 16 will move up and down. Further, the movement of the impact rod 16 collides with the shaking plate 18. With the cooperation of the spring 12, the shaking plate 18 shakes, so that the chips on its surface slide towards the through groove 5. Further, the chips quickly slide out of the collection box 2 through the through groove 5, discharging the generated chips, which is convenient for the staff to collect and process them later.

[0032] Working principle: When fixing a square workpiece, place the square workpiece on the surface of the placement plate 15, and then start the hydraulic telescopic rod 9. The output end of the hydraulic telescopic rod 9 pushes the clamping block 7, so that the clamping block 7 slides to fix and clamp the square workpiece. And when machining a cylindrical workpiece, place the cylindrical workpiece into the first limiting groove 8, and then the staff starts the hydraulic telescopic rod 9. The output end of the hydraulic telescopic rod 9 pushes the clamping block 7 to move, and clamps and fixes the cylindrical workpiece placed in the first limiting groove 8. Furthermore, this device can clamp and fix both cylindrical workpieces and square workpieces.

[0033] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can also be made without departing from the gist of the present invention.
