[0020] 1. The oil cylinder test bench fixes the position of the oil cylinder and tests the pressure performance of the oil cylinder by setting a test mechanism and a fixing mechanism. When the oil cylinder is tested for performance, the oil cylinder is placed on the test bench. During the process of opening and closing the oil cylinder, the oil cylinder is prone to shaking or the position of the oil cylinder changes, resulting in a change in the position of the pressure point. Therefore, a test mechanism and a fixing mechanism are set to fix the base position of the oil cylinder, and the position of the test mechanism can be adjusted to solve the above problem.

[0021] 2. The oil cylinder test bench performs pressure test on the oil cylinder by setting up a test mechanism.

[0022] 3. The oil cylinder test bench fixes the position of the oil cylinder base and the oil pipe by setting a fixing mechanism. When the oil cylinder is tested for performance, the oil cylinder is placed on the test bench. During the process of opening and closing the oil cylinder, the oil cylinder is prone to shaking or the position of the oil cylinder changes, resulting in a change in the position of the pressure point. Therefore, a fixing mechanism is set to fix the oil cylinder base to solve the above problem. Four oil tanks are set in the equipment, and the four oil tanks are connected to four oil pipes. When conducting comparative tests on both sides, the corresponding oil pipes are selected. The oil pipes used are replaced when multiple tests are performed to avoid long-term use of the same oil tank and oil pipe, which will increase the oil temperature in the oil tank and affect the test results.

[0023] 4. The oil cylinder test bench clamps and fixes the oil cylinder base by setting a clamping assembly. After clamping and fixing the base of the oil cylinder, the two sides of the middle position of the oil cylinder can be fixed by adjusting the position of the arc-shaped fixing plate to improve the stability of the oil cylinder. Flow grooves are opened in the upper and lower clamping plates to facilitate the placement of oil pipes. Two cylinders and a clamping ring are set on the top of the upper clamping plate to place two oil pipes and fix and limit the position of the oil pipes. BRIEF DESCRIPTION OF THE DRAWINGS
