[0002] Variable displacement valves are commonly used in hydraulic systems. They are devices that can adjust the output flow of hydraulic pumps. In hydraulic systems, hydraulic pumps usually run at a constant speed, and variable displacement valves can meet the system's demand for hydraulic power by adjusting the output flow of the pump. The working principle of variable displacement valves is to adjust the working pressure and flow of the hydraulic system by changing the amount of oil output by the hydraulic pump. This valve is usually controlled by an electronic, mechanical or hydraulic control system to achieve precise regulation of the flow and pressure output of the hydraulic system. In the fields of engineering and machinery, variable displacement valves are often used in situations where the output of the hydraulic system needs to be adjusted according to changes in workload. They can be used to improve the energy efficiency of the system, reduce power loss, and meet the flow requirements under different working conditions. In general, variable displacement valves play a very important role in hydraulic systems. They can effectively adjust and control the output flow of the hydraulic system to meet the needs of different working conditions and improve the efficiency and reliability of the system.

[0003] In the existing technology, when the variable displacement valve is performing pressure testing, different types of components need to be replaced for different types of valves, and valves of different models and sizes cannot be quickly clamped. The practicality is low and the operation is cumbersome. At the same time, the variable displacement valve will also generate vibration during the detection operation, which can easily cause damage to the valve. Therefore, a variable displacement valve pressure detection device is proposed to solve the above problems. Utility Model Content

[0022] Example

[0023] Depend on Figure 1-4 Provided is a variable displacement valve pressure detection device, comprising a base plate 1 and a pressure detector 3;

[0024] The pressure detector 3 is mounted on one side of the upper end surface of the bottom plate 1, and a mounting plate 11 is mounted on the other side of the upper end surface of the bottom plate 1. Four slide bars 12 are mounted on one side of the mounting plate 11, and the four slide bars 12 are distributed in a rectangular shape, and a clamping assembly 2 is mounted between the four slide bars 12;

[0025] The clamping assembly 2 includes a limit plate 20 that slides on four slide rods 12. A drive motor 21 is installed on one side of the limit plate 20 close to the mounting plate 11 and a disc seat 22 is installed on the other side. A connecting rod 23 is connected to the output end of the drive motor 21 and the connecting rod 23 passes through the limit plate 20 and the disc seat 22. A main gear 24 is installed on the outside of one end of the connecting rod 23. A plurality of arc-shaped slide grooves 241 are arranged around the main gear 24. A plurality of slide grooves 221 are arranged around the disc seat 22 and slide plates 25 are slidably arranged in the plurality of slide grooves 221. Positioning columns 26 are installed at one end of the plurality of slide plates 25 and the plurality of positioning columns 26 are distributed in a circle. The plurality of positioning columns 26 are respectively embedded and slid in the plurality of arc-shaped slide grooves 241. The other ends of the plurality of slide plates 25 are each equipped with an arc plate 27.

[0026] In this embodiment, through the mutual cooperation between the components in the clamping assembly 2, the inspector controls the driving motor 21 so that the driving motor 21 drives the connecting rod 23 connected to the output end to rotate, thereby driving the main gear 24 outside the connecting rod 23 to rotate. When the main gear 24 rotates, the positioning columns 26 in the several arc-shaped slide grooves 241 provided on the main gear 24 are driven to slide within the stroke range of the arc-shaped slide grooves 241, and drive the several slides 25 to move within the stroke range of the slide grooves 221, finally clamping the several arc plates 27 in pairs, quickly clamping the variable displacement valve, reducing the time and tediousness of replacing components. At the same time, the adjustability of the several arc plates 27 enables the device to adapt to variable displacement valves of different models and sizes, thereby improving the overall versatility and applicability of the device.

[0027] Specifically, refer to Figure 1-4 A plurality of arc-shaped plates 27 are provided with grooves on their inner sides and a plurality of sleeves 271 are installed in the grooves in a linear array. A plurality of sleeves 271 are installed with compression springs 272. A plurality of compression springs 272 are hooked with pressure rods 273 at the other ends, and an arc-shaped clamping plate 274 is installed at one end of the plurality of pressure rods 273.

[0028] In this embodiment, by installing the sleeve 271, the compression spring 272 and the pressure rod 273 between the arc plate 27 and the arc clamping plate 274, the arranged compression spring 272 can effectively reduce the vibration and damage to the variable displacement valve during detection, and can play a certain buffering and protective role, which helps to extend the service life of the variable displacement valve and reduce maintenance costs.

[0029] Specifically, refer to Figure 1A plurality of control buttons 31 are arranged on one side of the pressure detector 3, and a pressure gauge 32 is mounted on the upper end surface of the pressure detector 3.

[0030] In this embodiment, by pressing the control button 31 and starting the pressure detector 3, the variable displacement valve clamped by the clamping assembly 2 can be pressure tested. During the test, the data of the pressure gauge 32 is observed, and the data of qualified and unqualified products are recorded.

[0031] Specifically, refer to Figure 3 One side of the disc seat 22 is rotatably connected to an auxiliary gear 28 via a rotating shaft. The auxiliary gear 28 is located on one side of the main gear 24 and meshes with the main gear 24 .

[0032] In this embodiment, the auxiliary gear 28 is meshed and connected with the main gear 24. The auxiliary gear 28 is used to assist the main gear 24 in rotating, so that the main gear 24 can rotate more stably.

[0033] Specifically, refer to Figure 3 Two positioning rods 222 are mounted on one side of the disc seat 22 and the two positioning rods 222 are arranged in parallel, and a stop plate 223 is mounted on one end of the two positioning rods 222 .

[0034] In this embodiment, the set back plate 223 is installed on one side of the disc seat 22 through two positioning rods 222. The set back plate 223 is used to block and protect the main gear 24, auxiliary gear 28 and other components from being infected by the variable displacement valve, and to avoid friction between one end of the variable displacement valve and the main gear 24, auxiliary gear 28 and other components.

[0035] Specifically, refer to Figure 4 The inner sides of the plurality of arc-shaped clamping plates 274 are provided with anti-slip patterns.

[0036] In this embodiment, by providing anti-skid patterns on the inner side of the arc-shaped clamping plate 274 , the friction force of the arc-shaped clamping plate 274 during clamping can be increased, thereby improving the overall stability of the device.

[0037] The variable displacement valve pressure detection device of the utility model:

[0038] In actual use, before using the device, the inspector first connects the set drive motor 21 to the external power supply, then slides the clamping assembly 2 to one side of the pressure detector 3, puts the variable displacement valve to be inspected into a plurality of arc-shaped clamping plates 274, starts the set drive motor 21, so that the drive motor 21 drives the connecting rod 23 connected to the output end to rotate clockwise. When the connecting rod 23 rotates, the main gear 24 outside the connecting rod 23 is driven to rotate accordingly. At this time, the positioning column 26 installed in the arc slot 241 is driven and moves within the stroke range of the arc slot 241, and slowly moves toward the center point of the main gear 24. At the same time, when the positioning column 26 moves, it will drive the connected slide plate 25, so that The slide plate 25 slides inward in the slide groove 221, eventually making the several arc plates 27 approach the variable displacement valve, and making the several arc clamping plates 274 clamp and fix the variable displacement valve. At this time, the several compression springs 272 between the arc plate 27 and the arc clamping plate 274 can buffer and protect the variable displacement valve. Then press the control button 31 and start the pressure detector 3 to perform pressure detection, observe the data of the pressure gauge 32 and record the data. After the detection is completed, control the drive motor 21 to drive the connecting rod 23 to rotate counterclockwise, so that the several arc clamping plates 274 expand outward and cancel the clamping of the variable displacement valve, remove the variable displacement valve that has been detected, and repeat the above operation to continuously perform pressure detection operations.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
