The clamping arms 15 are movably connected to clamping rods 14. The clamping side of the clamping rods 14 is machined with screw holes 23. The clamping rods 14 are fixedly connected to clamping hands 16 through the screw holes 23. The clamping arms 15 and clamping rods 14 are fixedly connected to locking bolts 17. The clamping rods 14 are provided in two sets and are symmetrically distributed about the vertical center line of the clamp 20. The bottom end of the track frame 1 is fixedly connected to a bracket 13, and the track frame 1 is supported on the ground by the bracket 13. Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the bottom of the clamping arm 15 is fixedly connected to the gear rail 3 via angle steel 19, which facilitates overall disassembly and replacement. The gear rail 3 can slide in the slide groove 2, thereby driving the clamping arm 15 to produce lateral displacement. The clamping arm 15 is movably connected to the clamping rod 14, which is used to finely adjust the clamping distance and improve the adaptability to the workpiece. The end of the clamping rod 14 is fixedly connected to the clamping hand 16 via screw hole 23. The clamping hand 16 is a replaceable structure and can be replaced with specific clamping parts, such as rubber pads, V-shaped groove clamping blocks, etc., according to the different shapes, sizes or materials of the workpieces, to adapt to round, irregular or easily damaged materials. At the same time, a locking bolt 17 is provided between the clamping rod 14 and the clamping arm 15, which can be locked and positioned after adjusting the clamping depth.

[0019] Multiple sets of fixing holes 12 are provided at both the front and rear ends of the outer wall of the track frame 1. The fixing holes 12 are evenly distributed along the length of the track frame 1. A fixing handle 18 is fixedly connected between the clamp 20 and the fixing holes 12. Track grooves 11 are machined at both ends and the top of the outer wall of the track frame 1. Track side wheels 22 are installed at both ends of the inner wall of the clamp 20. Track top wheel 21 is installed at the top of the inner wall of the clamp 20. The track top wheel 21 and the clamp 20 are respectively embedded in the track groove 11 to form a rolling connection. Specifically, such as Figure 1 and Figure 2 As shown, the fixture 20 can be moved horizontally along the length of the track frame 1. The two ends of its inner wall are respectively equipped with track side wheels 22 and track top wheels 21. The track wheel set is embedded in the track groove 11 machined on the outer wall of the track frame 1 to form a rolling fit connection. During use, the fixture 20 can be moved smoothly by low resistance rolling. When the fixture 20 moves to the target work position, it is fixed to the fixing hole 12 of the track frame 1 by the fixing handle 18 set at the bottom of the fixture 20.

[0020] The bottom of the outer wall of the fixture 20 is provided with a groove 2, and the outer wall of the gear rail 3 is machined with a slider 10. The slider 10 slides in the groove 2. The top of the fixture 20 is fixedly connected to a hydraulic cylinder 8. The extension end of the hydraulic cylinder 8 is provided with a piston rod 9 and extends into the fixture 20. The bottom end of the fixture 20 is fixedly sleeved with a connecting frame 7. The two sides of the hydraulic cylinder 8 are respectively hinged with a boom 6. The other end of the boom 6 is movably sleeved with a small boom 5. The bottom end of the small boom 5 is fixedly connected with a gear 4. The gear 4 meshes with the gear rail 3. The bottom end of the small boom 5 is rotatably connected to the inner wall of the fixture 20. The gear 4 is a bevel gear. Specifically, such as Figure 1 and Figure 2 As shown, a hydraulic cylinder 8 is fixedly connected to the top of the clamp 20. The piston rod 9 inside the hydraulic cylinder 8 can extend downward under the action of a control signal, pushing the connecting frame 7 to move downward synchronously. The two sides of the connecting frame 7 are respectively hinged to the boom 6. The other end of the boom 6 is movably connected to the arm 5. The bottom end of the arm 5 is rotatably connected to the inner wall of the clamp 20, forming a set of linkage crank structures. When the piston rod 9 extends, the boom 6 and the arm 5 swing together. The arm 5 drives the bevel gear 4 fixed at its bottom end to rotate. The bevel gear 4 meshes with the gear rail 3, driving the gear rail 3 to move outward, thereby driving the clamping arm 15 to open outward. When the piston rod 9 retracts, it drives the clamping arm 15 to close and clamp the workpiece in the opposite direction. At the same time, the gear rail 3 is machined with a slider 10, which is embedded in the slide groove 2 to move, ensuring that the movement of the clamping arm 15 is smooth and without jamming during the opening and closing process.

[0021] The computer software involved in the hydraulic cylinder 8 carrier in the technical solution is software technology known to those skilled in the art; it is merely applied to the aforementioned hardware carrier. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carrier, nor is it a key technical point of the invention.

[0022] Working Principle: Before installation, the track frame 1 is supported on the ground by the bottom bracket 13. The clamp 20 is installed on the track frame 1. The inner wall of the clamp 20 is equipped with track side wheels 22 and track top wheels 21. The side wheels and top wheels are embedded in the track grooves 11 machined at both ends and the top of the track frame 1 to form a rolling connection. The operator can manually or with the help of the drive mechanism push the clamp 20 to move along the length of the track frame 1 to achieve rapid adjustment of the overall position. After the clamp 20 moves to the target position, the operator aligns the fixing handle 18 on the clamp 20 with the fixing holes 12 at the front and rear ends of the outer wall of the track frame 1 to ensure that there is no slippage during installation. After the clamp 20 is positioned, the hydraulic cylinder 8 is started. The hydraulic cylinder 8 starts after receiving the control signal, driving the piston rod 9 to extend downward and drive the connecting frame 7 to move downward. The two sides of the connecting frame 7 are hinged to the boom 6. The end of the boom 6 is movably connected to the forearm 5. The bottom of the forearm 5 is fixedly connected to the bevel gear 4. As it rotates, the bevel gear 4 meshes with the toothed rail 3, causing the toothed rail 3 to slide laterally along the slide groove 2 under the drive of the bevel gear 4. This causes the clamping arm 15 fixed on it to expand outward synchronously. During the sliding of the clamping arm 15, the slider 10 on its outer wall is embedded in the slide groove 2 for guidance and sliding, ensuring smooth movement without jamming. Each clamping arm 15 is movably connected to a clamping rod 14, and the end of the clamping rod 14 is provided with a screw hole 23 for connecting with the clamping hand 16. The clamping hand 16 can be quickly replaced according to the shape and size of the workpiece to be clamped, realizing the replaceable and adaptable function of the fixture 20. The clamping rod 14 and the clamping arm 15 are locked together by a locking bolt 17, which allows for fine adjustment of the clamping distance to ensure clamping accuracy. After clamping, the hydraulic cylinder 8 remains locked, so that the clamping arm 15 stably clamps the workpiece. If it is necessary to release the workpiece, simply control the hydraulic cylinder 8 to retract the piston rod 9, and the linkage mechanism drives the bevel gear 4 to rotate in the opposite direction, the toothed rail 3 resets inward, and the clamping arm 15 retracts synchronously, thus completing the quick clamping operation.
