[0002] A complete hydraulic system consists of five parts: power components, actuators, control components, auxiliary components, and hydraulic medium. Common actuators include piston hydraulic rods, plunger hydraulic rods, oscillating hydraulic rods, and combined hydraulic rods. During long-term operation, as the piston wears down, leaks and hydraulic failures may occur. In such cases, the piston needs to be replaced, and the hydraulic component's pressure is tested by injecting hydraulic fluid to ensure that the hydraulic rod pressure value after piston replacement meets the usage standards. Typically, a standard piston is first installed in the old rod, then normal hydraulic fluid is injected, and the hydraulic rod's support force is tested. Based on the hydraulic rod's support force, the piston is further adjusted and installed.
[0003] However, the current method of installing hydraulic rods at the working position for testing poses certain safety hazards, as the equipment may fall due to hydraulic rod failure. Therefore, those skilled in the art have provided a hydraulic component pressure regulating fixture to solve the problems mentioned in the background section. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-4This utility model provides a hydraulic component pressure regulating fixture technical solution: It includes a base plate 1, with a long plate 101 fixedly installed on the left end of the outer top surface of the base plate 1, and a long plate 202 provided on the right end of the outer top surface of the base plate 1. Support plates 103 and 104 are respectively fixedly installed on the outer top surfaces of the long plates 101 and 102. A reciprocating assembly 2 for driving the long plate 202 to move relative to each other along the outer top surface of the base plate 1 is provided on the right outer wall of the long plate 101. The reciprocating assembly 2 includes a threaded rod 201 rotatably installed at the center of the right outer wall of the long plate 101, one end of which extends to the right outer wall of the long plate 202 and is fixedly installed with a knob 202. The front and rear ends of the left outer wall of the long plate 202 are also connected. A circular hole 203 is provided on the outside of the threaded rod 201. Guide rods 204 are slidably connected inside the two circular holes 203. At the front and rear ends of the outer top surface of the base plate 1 and below the long plate 2 102, there are slots 205 arranged in an array. One end of the two guide rods 204 is fixedly connected to the inner wall of the circular hole 203 through a return spring 206. The other end of the two guide rods 204 extends to the outside of the circular hole 203 and is fixedly connected to the outer wall of the long plate 2 102. Square sleeves 207 are fixedly installed at the front and rear ends of the right outer wall of the long plate 2 102. A U-shaped limiting plate 208 is inserted into the inner side of the two square sleeves 207. At the same time, both ends of the outer bottom surface of the U-shaped limiting plate 208 are inserted into the inner side of the slot 205. First, to test the dimensions of the workpiece, turn the knob 202 to drive the threaded rod 201 to rotate, thereby driving the long plate 102 to slide back and forth along the base plate 1. During the sliding process, the long plate 102 slides inside the round hole 203 through the guide rod 204, thereby improving the stability of the long plate 102 during movement. At the same time, when it slides to the appropriate position, insert the U-shaped limiting plate 208 along the inner side of the two square sleeves 207 into the corresponding slots 205 to limit the long plate 102. This allows for testing of workpieces of different lengths, improving practicality.
[0027] The outer top surface of the second long plate 102 is provided with a receiving component 3 for supporting the test workpiece. The receiving component 3 includes a first support block 301 fixedly installed on the outer top surface of the second long plate 102 and near one end of the first long plate 101. The outer top surface of the first support block 301 is provided with a second support block 302. An arc-shaped groove 303 is opened on the outer surface of the corresponding side of the first support block 301 and the second support block 302. The rear outer wall of the second support block 302 is rotatably connected to the first support block 301 via a rotating shaft. Limiting blocks 304 are fixedly installed on the front outer walls of the first support block 301 and the second support block 302. At the same time, the two limiting blocks 304 are fixed to each other by screws. The workpiece to be tested is placed on the arc-shaped groove 303 between support block 1 301 and support block 2 302, and the bottom of the workpiece is made to abut against the outer wall of support plate 2 104. Then, the screw is turned to fix the two limit blocks 304 to each other, thereby fixing the workpiece on support block 1 301 and support block 2 302, so that the workpiece can be tested stably without causing safety hazards when the piston is replaced.
[0028] A pressure sensor 105 is fixedly installed at the center of the right outer wall of support plate 103. Sliding rods 4 are slidably sleeved at both ends of the right outer wall of support plate 103, outside the pressure sensor 105. A sliding block 401 is fixedly connected to the outer wall of the right end of both sliding rods 4. A return spring 402 is provided on the outside of both sliding rods 4, and both ends of the two return springs 402 are fixedly connected to support plate 103 and sliding block 401 respectively. During testing, the piston inside the workpiece slides towards the sliding block 401 under the action of oil, allowing the workpiece to move the sliding block 401 towards support plate 103. With the assistance of the sliding rods 4 and the return springs 402, the outer wall of the sliding block 401 contacts and presses against the pressure sensor 105, achieving the purpose of detecting the workpiece support pressure. Simultaneously, different operating conditions are simulated based on the different extension lengths of the workpiece piston rod.
[0029] The working principle of this utility model is as follows: When in use, the knob 202 is turned to drive the threaded rod 201 to rotate, so that the long plate 102 slides back and forth along the base plate 1. When it slides to a suitable position, the U-shaped limiting plate 208 is inserted into the corresponding slot 205 along the inner side of the two square sleeves 207 to limit the long plate 102.
[0030] Meanwhile, the workpiece to be tested is placed on the arc-shaped groove 303 between support block 1 301 and support block 2 302, and the two limiting blocks 304 are fixed to each other by turning the screw, so as to fix the workpiece to support block 1 301 and support block 2 302.
[0031] At the same time, the piston inside the test workpiece, under the action of the oil, drives the piston rod towards the side of the sliding block 401 to slide, so that the workpiece can drive the sliding block 401 to slide towards the support plate 103. With the assistance of the slide rod 4 and the return spring 402, the outer wall of the sliding block 401 comes into contact with the pressure sensor 105 and squeezes the pressure sensor 105, thereby achieving the purpose of detecting the support pressure of the workpiece.
[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
