Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valve testing, in particular to a hydraulic valve comprehensive performance test bench. Background Art

[0002] The hydraulic valve comprehensive performance test bench is a device specially used to test and evaluate the performance of hydraulic valves. Hydraulic valves are widely used in various hydraulic systems, such as industrial equipment, automobiles, construction machinery, aerospace, etc. The main function of the test bench is to simulate the working environment in the hydraulic system and conduct comprehensive performance tests on the hydraulic valves to ensure their reliability and effectiveness in actual applications.

[0003] A search revealed Chinese patent publication number CN221628579U, which discloses a hydraulic valve comprehensive performance test bench, belonging to the technical field of hydraulic valve performance test benches. The hydraulic valve comprehensive performance test bench comprises a test bench body. The movement of the slider drives the connecting column and movable block, which in turn drives the second locking plate away from the surface of the oil pipe. This movement of the movable block then compresses the spring, pulling the end of the oil pipe, causing the storage box to rotate on the surface of the spring shaft. The oil pipe wrapped around the storage box is then pulled out. After the oil pipe is pulled to the desired length, the slider is released, and the movable block returns to its original position under the action of the spring. The return movement of the movable block drives the second locking plate toward the first locking plate, which then engages with the first locking plate to clamp and secure the oil pipe. After the hydraulic valve test is completed, the oil pipe is retracted into the storage box, avoiding tangled lines during pipe arrangement. This not only keeps the test bench surface clean but also facilitates quick and easy pipe arrangement.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figure 1-Figure 3The utility model provides an embodiment: a hydraulic valve comprehensive performance test bench, including a machine base 1, a plurality of fixed shells 2 are fixedly connected to the front wall of the machine base 1, the front walls of the plurality of fixed shells 2 are rotatably connected to the rotating rods 4, the rear ends of the plurality of rotating rods 4 are all penetrated into the fixed shell 2 and the middle is fixedly connected to the rotating disk 6, the front and rear diameters of the rotating disk 6 are larger than the middle diameter of the rotating disk 6, the front and rear walls of the plurality of rotating disks 6 are fixedly connected to one end of the torsion spring 7, the other ends of the plurality of torsion springs 7 are fixedly connected to the inner wall of the fixed shell 2, and the plurality of torsion springs 7 are all arranged on the rotating rod 4. The outer periphery of multiple turntables 6 is provided with connecting pipes 3, one end of multiple connecting pipes 3 passes through the lower side of the fixed shell 2 and is connected to the machine base 1, the other end of multiple connecting pipes 3 passes through the upper side of the fixed shell 2 and the outer periphery is fixedly connected with a fixed block 5, cleaning brushes 8 are provided on both sides of the upper middle part of multiple fixed shells 2, the upper ends of multiple connecting pipes 3 pass through the cleaning brush 8, and hanging grooves 13 are provided on the upper and lower walls of the rear of multiple fixed blocks 5. A hanging plate 14 is engaged in the hanging groove 13, and the hanging plate 14 is fixedly connected to the machine base 1, and adjacent fixed blocks 5 are engaged with each other.

[0022] When testing the various performances of the hydraulic valve, since the multiple fixing blocks 5 are fixed by the engagement between the card slot 1 11 and the card slot 2 12, when pulling the connecting pipe 3 to connect with the hydraulic valve, the multiple connecting pipes 3 can be pulled out at the same time under the action of the fixing block 5. When the multiple connecting pipes 3 are extended and need to be connected to different positions respectively, the staff can cancel the mutual engagement between the fixing blocks 5, thereby canceling the limit between the connecting pipes 3 and connecting them respectively. When the performance test of the hydraulic valve is completed, the staff can respectively connect the card slot 1 11 on the multiple fixing blocks 5 with the card slot 2 on the adjacent fixing block 5. 12 is engaged, thereby splicing multiple fixing blocks 5 and connecting tubes 3. Since the turntable 6 is driven to rotate when the connecting tube 3 is pulled out, and the torsion spring 7 connected to the front and rear sides is pulled when the turntable 6 rotates, the torsion spring 7 pulls the turntable 6 to reset and rewind the corresponding connecting tube 3, thereby achieving the effect of simultaneously pulling multiple connecting tubes 3 for connection and facilitating the reset and storage of the connecting tube 3. Moreover, under the action of the hanging plate 14 and the hanging groove 13, the connection end of the connecting tube 3 and the fixing block 5 can be positioned after the connecting tube 3 is reset, thereby further improving the neatness of the test bench. In this embodiment, the fixing block 5 is respectively provided with a first clamping groove 11 and a second clamping groove 12 on the left and right sides, and the adjacent fixing blocks 5 are fixed by the mutual cooperation of the first clamping groove 11 and the second clamping groove 12.

[0023] Reference Figure 1-Figure 3, assembly and disassembly components, the assembly and disassembly components are respectively arranged in the fixed blocks 5, and the assembly and disassembly components are used to install and disassemble between adjacent fixed blocks 5, and the assembly and disassembly components include multiple card slots 11, multiple card slots 11 are opened on one side of the fixed block 5, and multiple fixed blocks 5 are provided with card slots 2 12 on the other side. Card slots 2 12 are opened on the side away from card slot 11 and penetrated with holes matching the card block 9, and adjacent card slots 11 and card slots 2 12 are engaged with each other. The front walls of the multiple fixed blocks 5 are penetrated by buttons 10, and the upper and lower sides of the rear walls of the multiple buttons 10 are fixedly connected to springs 17. The upper and lower sides of the rear of the multiple buttons 10 are penetrated by limit rods 16, and the front and rear ends of the multiple limit rods 16 are fixedly connected to the front and rear walls of the fixed block 5, and the multiple springs 17 are It is arranged on the outer periphery of the limit rod 16, and the rear ends of multiple springs 17 are fixedly connected to the inner rear wall of the fixed block 5. The inner walls of multiple buttons 10 are rotatably connected with connecting plates 18, and the ends of multiple connecting plates 18 away from the buttons 10 are rotatably connected with fixed plates 19. The inner walls of multiple fixed plates 19 are fixedly connected with connecting rods 15, and guide rods 20 are slidably connected in multiple connecting rods 15. One end of multiple guide rods 20 passes through one end of the connecting rod 15 and is fixedly connected to the inner wall of the fixed block 5. The ends of multiple connecting rods 15 away from the fixed plate 19 are fixedly connected with card blocks 9. The width of one end of the card block 9 in the fixed block 5 is greater than the width of the other end. The end of the card block 9 away from the fixed block 5 is provided with an upward inclined groove, and multiple card blocks 9 pass through card slot 11.

[0024] When the button 10 is pressed and moved backward, the connected connecting plate 18 will be driven to move. Since the length of the connecting plate 18 is constant and the rear end of the connecting plate 18 is connected to the fixing plate 19, the connecting rod 15 will be limited by the action of the guide rod 20, so that the fixing plate 19 and the connecting rod 15 can only move horizontally to both sides along the guide rod 20 under the action of the guide rod 20. Therefore, when the button 10 moves backward, it will drive the connecting plate 18 to rotate and pull the fixing plate 19 to drive the connecting rod 15 to move inside the fixed block 5. When the connecting rod 15 moves, it will drive the corresponding connected card block 9 to move inside the fixed block 5, and the button 10 will also compress the spring 17 when it moves backward. When the spring 17 is compressed, it will provide an opposite force. Therefore, after releasing the button 10, the button 10 can be reset under the action of the spring 17, and the guide rod 20 can ensure the stability of the button 10 movement and prevent the spring 17 from bending under pressure.

[0025] Therefore, when the staff needs to use one connecting tube 3 alone, by pressing the button 10 of the fixing block 5 on the corresponding connecting tube 3, the corresponding connected card block 9 can be retracted into the fixing block 5, thereby canceling the locking and fixing of the two fixing blocks 5, and then the card slot 11 on the fixing block 5 can be pulled out from the card slot 2 12 on the other fixing block 5 to realize the disassembly of the fixing block 5. When the fixing blocks 5 need to be spliced, it is only necessary to lock the card slot 11 on one fixing block 5 into the card slot 2 12 on the other fixing block 5. During the locking process, the card block 9 will be squeezed to move into the fixing block 5 and compress the spring 17. Therefore, after the card slot 11 and the card slot 2 12 are fully locked, the card block 9 will extend and be locked and fixed, thereby achieving the effect of facilitating the assembly and disassembly of the fixing blocks 5.

[0026] Working principle: In actual use, when the connecting pipe 3 is connected and fixed to the hydraulic valve to be tested by pulling the connecting pipe 3, the connecting pipe 3 will stretch and drive the turntable 6 to rotate. When the turntable 6 rotates, it will also drive the connected torsion spring 7 to pull. Therefore, after the connecting pipe 3 and the hydraulic valve are disassembled, the turntable 6 can be pulled to rotate and reset under the action of the torsion spring 7, so that the corresponding connected connecting pipe 3 can be reeled and reset, and multiple connecting pipes 3 can also be connected by adjacent fixing blocks 5, so that multiple connecting pipes 3 can be stretched and connected at the same time. When it is necessary to stretch one connecting pipe 3 separately, pressing the button 10 can drive the connecting plate 18 to pull the fixing plate 19 to move, and the fixing plate 19 drives the connecting rod 15 and the blocking block 9 to move into the fixing block 5, so that the blocking block 9 can be pulled out from the card slot 11, so that the single fixing block 5 can be disassembled and the connecting pipe 3 can be used separately.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
