Description

Technical Field

[0001] This utility model relates to the field of booster cylinder testing technology, and in particular to a booster cylinder testing pressure table. Background Technology

[0002] A booster cylinder is a hydraulic component that converts low-pressure oil into high-pressure oil. Its core function is to amplify and transmit pressure through the ingenious design of its mechanical structure. In the field of industrial production, booster cylinders are used in many processes such as metal forming, plastic injection molding, and automotive parts processing. They can provide powerful and stable power support for various mechanical equipment, significantly improve production efficiency and processing accuracy, and effectively reduce energy consumption costs. They are an indispensable key component in modern manufacturing.

[0003] The booster cylinder test pressure bench is a specialized device for testing the performance of booster cylinders. It is mainly used to simulate the pressure conditions of booster cylinders in actual working scenarios and to test their core performance indicators such as pressure output, sealing, and stability. Through a scientific and standardized testing process, potential quality problems of booster cylinders can be identified in a timely manner, providing a reliable basis for product quality control and performance optimization, and ensuring that the booster cylinders leaving the factory meet actual production needs.

[0004] However, existing pressure testing benches for booster cylinders use fixed hydraulic lines and pressure regulating devices to perform pressure tests on booster cylinders. While this can ensure the acquisition of basic test data to a certain extent and avoid test errors caused by a lack of specialized equipment, the standardized design of their pressure regulating modules and fixed connection structures means that the operating parameters of each component are relatively fixed. When faced with booster cylinders of different specifications and models, it is impossible to adjust the test pressure range, test interface size, and key parameters such as pressure loading rate. This results in the pressure bench being unable to perform tests on different booster cylinders, making it difficult to meet diverse testing needs and reducing testing efficiency and accuracy.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a pressure test bench for a booster cylinder, comprising a workbench 1 for supporting various components and booster cylinders required for testing, providing a test operation platform. Columns 4 are fixedly connected to the four corners of the bottom of the workbench 1 to support the workbench 1 and ensure the stability of the entire pressure bench during the testing process. A clamping mechanism 2 is provided on the top of the workbench 1 for clamping and fixing the booster cylinder. A connecting mechanism 3 is provided at the bottom of the workbench 1 for connecting and adjusting the position of the pressure cylinder 207 to the workbench 1.

[0033] The clamping mechanism 2 includes multiple upright plates 201 for mounting threaded rods 202, serving as the basic structure for clamping the booster cylinder. The bottoms of the multiple upright plates 201 are slidably connected to the top of the worktable 1, allowing for adjustment of the position of the upright plates 201 to accommodate booster cylinders of different sizes. Each of the multiple upright plates 201 has a groove 203 on one side to accommodate the moving block 204 and provide space for its movement. The tops of the multiple upright plates 201 are rotatably connected to threaded rods 202. Rotating the threaded rods 202 can drive the moving block 204 to move. The bottom ends of the multiple threaded rods 202 pass through the grooves 203 and are threadedly connected to the moving block 204. Driven by the threaded rods 202, the moving block moves along the grooves 203, thereby driving the clamping plate 205 to move. Each of the multiple moving blocks 204 has a clamping plate 205 fixedly connected to one side for directly clamping the booster cylinder and fixing it.

[0034] The top of the workbench 1 has a circular groove 206 for positioning the fixed plate 208 at the bottom of the pressure cylinder 207. The pressure cylinder 207 is installed on the top of the workbench 1 to generate the pressure required for testing and to perform pressure testing on the booster cylinder. The bottom of the pressure cylinder 207 is fixedly connected to the fixed plate 208, which cooperates with the circular groove 206 on the top of the workbench 1 to achieve the initial positioning of the pressure cylinder 207. Pressure gauges 209 are fixedly connected to the upper front side of the pressure cylinder 207 to display the pressure value inside the pressure cylinder 207 in real time, so that the tester can read the data. An airtight component 210 is installed on the left side of the pressure cylinder 207 to test the airtight performance of the booster cylinder. The bottom of the multiple upright plates 201 is provided with a moving component 211 to enable the upright plates 201 to slide on the workbench 1, so as to facilitate the adjustment of the position of the upright plates 201. An adjustment component 212 is installed on the top of the workbench 1 to fix the adjusted position of the upright plates 201.

[0035] The airtight component 210 includes a water tank 2101 for holding water. The airtightness of the booster cylinder is determined by observing whether bubbles are generated in the water. The bottom of the water tank 2101 is fixedly connected to the top left side of the workbench 1 to fix its position. The left side of the pressure cylinder 207 is connected to an air pipe 2102 to transfer the gas in the pressure cylinder 207 to the water tank 2101. The other end of the air pipe 2102 is connected to the left side of the water tank 2101 to allow the gas to enter the water tank 2101 smoothly. The moving component 211 includes multiple moving blocks 2112 fixed to the bottom of the upright plate 201. They cooperate with the moving slots 2111 on the workbench 1 to move the upright plate 201. The tops of the multiple moving blocks 2112 are respectively fixedly connected to the bottom of the corresponding upright plate 201 to connect the upright plate 201 with the moving blocks 2112. The workbench 1 has multiple moving slots 2111 on its top, which cooperate with the moving block 2112 to provide a track for the movement of the upright plate 201. The adjustment assembly 212 includes multiple extension blocks 2121 for installing adjustment bolts 2122 to fix the position of the upright plate 201. Each side of the multiple upright plates 201 is fixedly connected to an extension block 2121 to connect the extension block 2121 to the upright plate 201. The workbench 1 has multiple adjustment holes 2123 around its top, which cooperate with the adjustment bolts 2122 to fix the extension blocks 2121 and the upright plate 201. Each top of the multiple extension blocks 2121 is rotatably connected to an adjustment bolt 2122. By turning the adjustment bolt 2122, it is screwed into the adjustment hole 2123 to fix the position of the upright plate 201.

[0036] Specifically, the column 4 at the bottom of the workbench 1 provides stable support, ensuring the stability of the pressure table during testing. In the clamping mechanism 2, the second movable block 2112 at the bottom of the upright plate 201 can slide within the first movable slot 2111 at the top of the workbench 1. This, combined with the connection between the adjusting bolt 2122 at the top of the extension block 2121 in the adjusting assembly 212 and the adjusting hole 2123 at the top of the workbench 1, allows for flexible adjustment and fixation of the upright plate 201. Rotating the threaded rod 202 can drive the first movable block 204 to... The cylinder moves within the groove 203, thereby driving the clamping plate 205 to firmly clamp the booster cylinder. The fixing plate 208 at the bottom of the pressure cylinder 207 is installed in the circular groove 206 at the top of the workbench 1. The pressure gauge 209 on its front side can display the pressure value in real time, providing data support for pressure testing. In the airtight component 210, the air pipe 2102 connected to the left side of the pressure cylinder 207 introduces the internal gas into the water tank 2101. By observing whether bubbles are generated in the water tank 2101, the airtight performance of the booster cylinder can be accurately judged.

[0037] Reference Figure 2 , Figure 4 and Figure 5The connecting mechanism 3 includes a movable plate 301 for supporting the cylinder 302 and the pressure cylinder 207, and can slide along the outer wall of the column 4 to adjust its height. The movable plate 301 is slidably connected to the outer wall of multiple columns 4 to realize the vertical position adjustment of the movable plate 301 to meet different testing requirements. The top of the movable plate 301 is fixedly connected to the cylinder 302 for mounting the pressure cylinder 207 and providing a support structure for the pressure cylinder 207. The top of the cylinder 302 has a mounting groove 303 for cooperating with the mounting block 304 at the bottom of the pressure cylinder 207 to achieve the initial positioning of the pressure cylinder 207. The interior of the mounting groove 303 is slidably connected. A mounting block 304 is attached to the bottom of the pressure cylinder 207 and cooperates with the mounting groove 303 to allow the pressure cylinder 207 to be quickly installed on the cylinder 302. The top of the mounting block 304 is fixedly connected to the bottom of the pressure cylinder 207, connecting the pressure cylinder 207 to the mounting block 304 to ensure the stability of the pressure cylinder 207 installation. Slots 305 are provided on the front and rear sides of the right end of the cylinder 302 for inserting insert plates 306 to further fix the pressure cylinder 207. Insert plates 306 are slidably connected inside both slots 305. After inserting into the slots 305, the horizontal movement of the pressure cylinder 207 can be restricted, enhancing its fixing effect.

[0038] A second movable groove 307 is provided at the top front left end of the movable plate 301, which is used to cooperate with the measuring plate 308 at the bottom of the workbench 1 to measure and calibrate the moving position of the movable plate 301. The measuring plate 308 is fixedly connected to the bottom of the workbench 1 and cooperates with the second movable groove 307. By observing the position of the measuring plate 308 in the second movable groove 307, the moving distance of the movable plate 301 can be determined. The bottom end of the measuring plate 308 passes through the second movable groove 307, so that the measuring plate 308 and the second movable groove 307 form a mating structure, which facilitates the positioning of the movable plate 301. Limit components 309 are provided at the left ends of the two circular grooves 206. To further secure the insert plate 306 and prevent it from loosening, the limiting component 309 includes two limiting blocks 3091, which cooperate with the limiting groove 3092 on the insert plate 306 to limit the insertion plate 306. The two limiting blocks 3091 are slidably connected to the top left end of the corresponding insert plate 306. After the insert plate 306 is inserted into the slot 305, the insert plate 306 is locked by sliding into the limiting groove 3092. The top left end of both insert plates 306 has a limiting groove 3092, which cooperates with the limiting blocks 3091 to restrict the movement of the insert plate 306 and ensure the stability of the pressure cylinder 207 installation.

[0039] Specifically, the connecting mechanism 3 ensures the installation and adjustment of the pressure cylinder 207. The moving plate 301 slides along the outer wall of the column 4. The height is precisely adjusted by the cooperation of the measuring plate 308 and the moving groove 307. The mounting block 304 at the bottom of the pressure cylinder 207 is inserted into the mounting groove 303 of the cylinder 302 for initial positioning. After the insert plate 306 is inserted into the slot 305, the limiting insert block 3091 slides into the limiting groove 3092 to achieve a stable lock of the pressure cylinder 207. The pressure gauge 209 on the front of the pressure cylinder 207 displays the pressure data in real time. The air pipe 2102 on the left side connects to the water tank 2101 to form an airtight component 210. The airtightness of the booster cylinder is judged by observing the bubbles in the water tank 2101. All components work closely together to enable the pressure table to efficiently and reliably complete the pressure test and performance inspection of the booster cylinder.

[0040] Reference Figure 3 Each of the multiple movable blocks 2112 has a limit block 8 fixedly connected to both sides to prevent the movable block 2112 from shifting or coming out when it moves in the movable groove 2111. Each of the multiple movable grooves 2111 has a limit groove 7 on both sides inside, which cooperates with the limit block 8 to provide guidance and limit for the movement of the movable block 2112, ensuring that the upright plate 201 moves smoothly. Each of the multiple grooves 203 has a sliding groove 6 on both sides inside, which provides guidance and support for the movement of the movable block 204, ensuring the stability of the movement of the movable block 204. Each of the multiple movable blocks 204 has a slider 5 fixedly connected to both sides, which slides in cooperation with the sliding groove 6, so that the movable block 204 can move smoothly in the groove 203 in a predetermined direction, thereby driving the clamping plate 205 to stably clamp the booster cylinder.

[0041] Specifically, during the movement of the upright plate 201, the movement block 2112 is prevented from detaching from the movement groove 2111, and the movement direction of the movement block 2112 is limited. The slider 5 is installed on both sides of the movement block 204 and is slidably connected to the sliding grooves 6 on both sides inside the groove 203. When the rotating threaded rod 202 drives the movement block 204 to move, the slider 5 slides in the sliding groove 6 to provide guidance and support for the movement block 204, so that the movement block 204 can move smoothly in the groove 203, thereby ensuring that the clamping plate 205 stably clamps the booster cylinder.

[0042] Working principle: The position of the clamping mechanism 2 is adjusted by the moving component 211. The moving block 2112 can slide in the moving groove 2111 on the top of the workbench 1, driving the upright plate 201 to move. After the upright plate 201 is adjusted to a suitable position, the adjusting bolt 2122 on the top of the extension block 2121 is rotated to screw it into the adjusting holes 2123 around the top of the workbench 1, thereby fixing the upright plate 201. Then, the threaded rod 202 is rotated. The threaded rod 202 rotates on the top of the upright plate 201. Its bottom end passes through the groove 203 and drives the moving block 204 to move up and down in the groove 203. The moving block 204 pushes the clamping plate 205 to clamp and fix the pressure cylinder under test. During the test, the pressure cylinder 207 plays a core role. The fixing plate 208 at the bottom of 207 is firmly fixed at the top circular groove 206 of the workbench 1. The pressure gauge 209 on the upper front side can display the pressure value in real time. The pressure cylinder 207 applies test pressure to the booster cylinder through internal pressure changes to simulate the pressure environment in actual work. In the airtightness test, the airtightness component 210 starts to operate. The air pipe 2102 connected to the left side of the pressure cylinder 207 introduces the internal gas into the water tank 2101. If the booster cylinder under test has an airtightness problem, gas leakage will generate bubbles in the water tank 2101. By observing the bubble situation in the water tank 2101, the airtightness performance of the booster cylinder can be judged. During the entire test, the columns 4 at the four corners of the bottom of the workbench 1 play a supporting role to ensure the stability of the pressure table.

[0043] The operator first slides the movable plate 301 along the outer wall of the column 4 to the target height. At this time, the measuring plate 308 moves synchronously in the second movable slot 307 to calibrate the position of the movable plate 301. The mounting block 304 at the bottom of the pressure cylinder 207 is inserted into the mounting slot 303 of the cylinder 302, and then the insert plate 306 is slid into the slot 305 so that the limiting insert block 3091 and the limiting slot 3092 cooperate and lock, ensuring that the pressure cylinder 207 and the movable plate 301 are rigidly connected. The cooperation between the measuring plate 308 and the second movable slot 307 is not only used for positioning, but also works with the displacement sensor to monitor the stroke change of the pressure cylinder 207 in real time. These data are combined with the data of the pressure gauge 209 to form a complete test.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
