[0024] The present invention will now be described in further detail in conjunction with the full text.

[0025] Combined with appendix Figures 1-3 A hydraulic tooling fixture for a hydraulic cylinder includes a worktable 1. Two sets of support devices 2 for supporting workpieces are mounted on the worktable 1. Each support device 2 includes opposing piston housings 201. Guide rods 202 are movably installed inside each piston housing 201. A stop block 203 supporting the workpiece is installed at the upper end of each guide rod 202. A piston 4, used in conjunction with the piston housing 201, is installed on the outer side of each guide rod 202. A connecting pipe 5 connects the two piston housings 201 and the lower end of the piston 4. A return spring 6 is installed between the bottom wall of the piston housing 201 and the piston 4. Specifically, a steel ring is placed on the stop block 203 on the support device 2. When the steel ring is under force, the stop block 203 moves within the piston housing 201 via the guide rods 202 and the piston 4, compressing the gas at the bottom of the piston housing 201. The return spring 6 is compressed, completing the support. When the steel ring continues to be under force, the connecting pipe 5 reconnects the two sets of piston housings 201, interacting to provide support.

[0026] In specific implementation of this utility model, such as Figure 1 As shown, the workbench 1 is equipped with three sets of movable clamps 3 for clamping the upper surface of the workpiece. The three sets of movable clamps 3 can better clamp the steel ring. The movable clamps 3 are positioned inside the steel ring. The steel ring is placed on the support device 2 and then clamped by the movable clamps 3. The movable clamps 3 include a telescopic rod 301 fixedly connected to the workbench 1. The telescopic end of the telescopic rod 301 is hinged to a clamping arm 302. A connecting rod 303 is installed on the upper end of the telescopic rod 301. The upper end of the connecting rod 303 is hinged to a movable rod 304, and the upper end of the movable rod 304 is hinged to the middle of the clamping arm 302. Specifically, when the telescopic end of the telescopic rod 301 extends, it drives the clamping arm 302 to rotate and clamp the steel ring. The two ends of the movable rod 304 are respectively hinged to the clamping arm 302 and the connecting rod 303, which serves as a limit.

[0027] The telescopic rod 301 is fixedly connected to the workbench 1 by a bracket and bolts. Specifically, the telescopic rod 301 is fixedly connected to the workbench 1, and the steel pipe passes through the telescopic rod 301 and is placed on the support device 2.

[0028] The upper end of the abutment block 203 is provided with a rubber layer, which serves to protect the steel ring workpiece.

[0029] The working principle of this utility model:

[0030] The steel ring is placed on the abutment 203 on the support device 2. The telescopic end of the telescopic rod 301 extends, driving the clamping arm 302 to rotate and clamp the steel ring. The two ends of the movable rod 304 are respectively hinged to the clamping arm 302 and the connecting rod 303, which serves as a limit. When the steel ring is under force, the abutment 203 moves in the piston shell 201 through the guide rod 202 and the piston 4, compressing the gas at the bottom of the piston shell 201. The return spring 6 is compressed, completing the support. When the steel ring continues to be under force, the connecting pipe 5 connects the two sets of piston shells 201, which interact and provide support, providing a foundation for the subsequent processing of the steel ring.
