[0024] Please see Figure 1-5As shown, this utility model is a clamping device for hydraulic machinery, including a base 1 and a hydraulic cylinder body 2. In hydraulic machinery, the hydraulic cylinder body 2 is the core power actuator, composed of a high-strength alloy steel cylinder barrel, a chrome-plated hard alloy steel piston rod, a sealing system, and end caps, etc. This is existing technology and will not be described in detail here. The hydraulic cylinder body 2 is electrically connected to an external power source and controlled by an external program. A bidirectional clamping mechanism 3 is provided on the top of the base 1; the bidirectional clamping mechanism 3 includes four support columns 31 and fixed seats 32 fixedly connected to the top of the base 1. Fixing strips 33 are fixedly connected between the two front support columns 31 and between the two rear support columns 31. Two limiting strips 34 are fixedly connected to the top of each of the two fixing strips 33. A fixing plate 35 is fixedly connected between the tops of the two fixing strips 33. Sliding blocks 36 are slidably connected between the surfaces of the four limiting strips 34. The tops of adjacent sliding blocks 36 are fixedly connected... The system includes connecting plates 37, each top of which is equipped with a lifting adjustment component 38. A rotating bar 39 is rotatably connected to the top of a fixed plate 35, and two connecting arms 310 are rotatably connected to the top of the rotating bar 39. An electric telescopic rod 311 is fixedly connected to the top of a fixed base 32. The electric telescopic rod 311 can precisely control the extension and retraction accuracy, ensuring clamping precision. Its output shaft has a locking function, ensuring clamping stability after locking. The electric telescopic rod 311 is electrically connected to an external power source and controlled by an external program. A connecting seat 312 is fixedly connected to the output end of the electric telescopic rod 311. The connecting seat 312 is fixedly connected to the right-side connecting plate 37 via a connecting rod 313. The two connecting arms 310 are rotatably connected to adjacent connecting plates 37. By setting up a bidirectional clamping mechanism 3, only one drive component is used to achieve synchronous clamping of the workpiece from both sides through a transmission component, reducing operating costs.

[0025] The left bidirectional clamping mechanism 3 includes a connecting post 381 fixedly connected to the top of the left connecting plate 37. A lower clamping bar 382 is fixedly connected to the right end of the connecting post 381. Two limiting rods 383 are fixedly connected to the top of the lower clamping bar 382. A screw 384 is rotatably connected to the top of the lower clamping bar 382. A turning bar 385 is fixedly connected to the top of the screw 384. An upper clamping bar 386 is slidably connected between the surfaces of the two limiting rods 383. The upper clamping bar 386 and the screw 384 are threadedly connected. The inner wall of the upper clamping bar 386 is provided with a threaded groove that matches the screw 384.

[0026] The top of the base 1 is fixedly connected to a fixing frame 4 and four support rods 5 respectively. The hydraulic cylinder body 2 is fixedly connected to the inner wall of the fixing frame 4, and a placement seat 6 is fixedly connected between the top ends of the four support rods 5.

[0027] The bottom of the base 1 is fixedly connected to a support foot 7, and the bottom end of the support foot 7 is fixedly connected to a support base plate 8. The design of multiple support feet 7 ensures the stability of the equipment.

[0028] The two bidirectional clamping mechanisms 3 have the same structure and are symmetrically distributed on the top of the two connecting plates 37. The height of the upper clamping bar 386 can be adjusted in the lifting adjustment assembly 38, so that the device can adapt to workpieces of different sizes and clamp them better.

[0029] There are four support feet 7, which are arranged in a rectangular array at the bottom edge of the base 1.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] The working principle of this utility model is as follows: First, place the workpiece on the placement seat 6, hold the left-side turning bar 385 and rotate it to drive the screw 384 to rotate synchronously. When the screw 384 rotates, it drives the upper clamping bar 386 to move upward along the surface of the two limit rods 383 to adjust the height of the left upper clamping bar 386. Continue this operation to adjust the height of the right upper clamping bar 386. Then, start the electric telescopic rod 311 to drive the output shaft to retract, which in turn drives the right-side connecting seat 312 at the output end to move to the left. At the same time, the right-side connecting seat 312 moves, and the connecting rod 313 drives the right-side connecting plate 37 through the two sliding seats 36 at the bottom. The two limit bars 34 on the right side move to the left. While the connecting plate 37 moves, the right connecting arm 310 drives the rotating bar 39 to rotate on the fixed plate 35. When the fixed plate 35 rotates, the left connecting arm 310 drives the left connecting plate 37, so that the left connecting plate 37 moves to the right on the surface of the two limit bars 34 on the left side through the two slides 36 at the bottom. The two connecting plates 37 move to opposite sides, so that the two lower clamping bars 382 and the two upper clamping bars 386 on the two lifting adjustment components 38 clamp the two sides of the workpiece. After clamping the workpiece, the hydraulic cylinder body 2 is finally started to work.
