[0034] In this embodiment, when the multi-stage hydraulic cylinder vertical detection device is used, the hydraulic rod 3 and the mounting assembly 4 are used in cooperation to install and press the oil cylinder body 403 for detection. After the installation operation of the oil cylinder body 403 is completed, the initial position of the driving assembly 5 and the positioning assembly 6 is close to the main cylinder body position of the oil cylinder body 403, and the test plate 609 and the main cylinder body surface of the oil cylinder body 403 are in a state of adhesion. At this time, the spring 607 can apply pressure to the test plate 609 in the direction of the oil cylinder body 403. By using the laser displacement sensor 606, the distance between the laser displacement sensor 606 and the support seat 602 at this time is the initial distance. When the position of the side plate 605 changes, the distance between the laser displacement sensor 606 and the support seat 602 will change. Therefore, the use of the laser displacement sensor 606 can achieve the purpose of monitoring the position change and completing the switch control. When starting the detection work, the motor 503 is started to drive the side frame 502 to move upward. The side frame 502 can drive the two side supports 601 to move upward through the connection of the horizontal plate 501. The support seat 602 can be driven to move upward by the support seat 602. At this time, the test plate 609 always maintains the state of adhesion to the outer wall of the oil cylinder body 403 and moves upward. The spring 607 always provides support for the test plate 609. When the test plate 609 moves to the telescopic end position of the oil cylinder body 403, the outer wall size of the oil cylinder body 403 changes at this time.

[0035] Embodiment Two

[0036] Figure 8As shown, the first slide rail 702 is fixedly connected to the inner top of the stabilizing frame 701, the outer surface of the first slide rail 702 is symmetrically and slidably connected to the limiting block 703, the bottom of the limiting block 703 is fixedly connected to the moving seat 704, the top of the moving seat 704 is symmetrically and slidably connected to the slide rod 705, the lower end surfaces of the two slide rods 705 are fixedly connected to the pressing plate 706, the pressing plate 706 is located on the lower side of the moving seat 704, the bottom of the pressing plate 706 is fixedly connected to the plurality of connecting rods 707 at equal intervals, and the lower end surfaces of the plurality of connecting rods 707 are fixedly connected to the magnetic plate 708.

[0037] In this embodiment, when the test plate 609 is displaced and the hydraulic rod 3 is operated for testing, the multi-stage electric telescopic rod 709 is simultaneously started to extend, the multi-stage electric telescopic rod 709 can drive the stabilizing plate 710 to move downward after being operated to extend, the pressing plate 706 can be pressed by the downward movement of the stabilizing plate 710, a certain pressure can be applied to the oil cylinder body 403 from above, the pressure borne by the test plate 609 can be shared when the hydraulic rod 3 is operated to press and test the oil cylinder body 403, the test plate 609 can be prevented from being broken after being pressed, and the stability of the positioning assembly 6 structure during testing is improved.

[0038] Embodiment Three

[0039] Figure 6 As shown, the arc-shaped groove is formed in the outer surface of the side of the test plate 609 close to the oil cylinder body 403, a plurality of circular holes are uniformly formed in the inner bottom of the arc-shaped groove, and the plurality of circular holes are internally provided with the ball 610.

[0040] In this embodiment, when the test plate 609 is displaced while being attached to the outer wall of the oil cylinder body 403, the ball 610 will be attached to the outer wall of the oil cylinder body 403 and rotate, the rolling of the ball 610 can reduce the friction, thereby reducing the abrasion of the oil cylinder body 403 during testing.

[0041] The method for using the device and the working principle: when the multi-stage hydraulic oil cylinder vertical detection device is used, the hydraulic rod 3 is used in cooperation with the installation assembly 4 to install and press the oil cylinder body 403 for detection. When the oil cylinder body 403 is installed, the oil cylinder body 403 is placed in the central position above the bearing plate 401, and then the hole position of the oil cylinder body 403 is aligned with the installation hole 402 position. The oil cylinder body 403 and the bearing plate 401 are installed by using bolts. After the installation of the oil cylinder body 403 is completed, the pipeline and the oil pump connected to the oil cylinder body 403 are connected. After the connection is completed, the oil cylinder body 403 is driven to the extended state of each stage output end. Then, through the cooperation of the driving assembly 5, the positioning assembly 6 and the stabilizing assembly 7, the pressure of each stage output end of the oil cylinder body 403 is applied to complete the detection. The initial position of the driving assembly 5 and the positioning assembly 6 is close to the main cylinder body position of the oil cylinder body 403. At this time, the test plates 609 on both sides are in a state of close contact with the surface of the main cylinder body of the oil cylinder body 403. The test plates 609 on both sides are supported by the connection of the push frame 608. The push frame 608 is supported by the connection of the spring 607 and the plug rod 604. At this time, the springback force of the spring 607 can apply pressure to the test plate 609 in the direction of the oil cylinder body 403, so that the arc surface of the test plate 609 is in close contact with the surface of the oil cylinder body 403. Through the setting of the plug rod 604 inside the spring 607, the plug rod 604 can support the position of the spring 607 and the push frame 608, thereby improving the stability of the position of the push frame 608. When the test plates 609 on both sides are in close contact with the oil cylinder body 403, the test plates 609 are in a static state, so the side plates 605 on both sides are also in a static state. At this time, through the use of the laser displacement sensor 606, the distance between the laser displacement sensor 606 and the support seat 602 is the initial distance. When the position of the side plate 605 changes, the distance between the laser displacement sensor 606 and the support seat 602 will change. Therefore, the use of the laser displacement sensor 606 can achieve the purpose of monitoring the position change and completing the switch control. When the detection work starts, the motor 503 is started to rotate. After the motor 503 is started, the rotating shaft 504 can be driven to rotate. Through the rotation of the rotating shaft 504, the gear 505 can be driven to rotate. When the gear 505 rotates, the gear 505 can drive the side frame 502 to move up through the meshing of the gear 505 and the toothed plate 9. When the side frame 502 moves, the slide block 507 can be driven to move along the second slide rail 10 through the connection of the extension rod 506. At this time, the second slide rail 10 and the slide block 507 are used in cooperation to support and limit the displacement of the side frame 502. Through the upward movement of the side frame 502, the side frame 502 can drive the two side supports 601 to move up through the connection of the cross plate 501. The support seat 602 can move up. At this time, the test plate 609 always keeps close contact with the outer wall of the oil cylinder body 403 and moves up.The setting of providing support for the test plate 609 by the spring 607 all the time, when the test plate 609 moves to the telescopic end position of the cylinder body 403, at this time the size of the outer wall of the cylinder body 403 changes, so the spring-back force of the spring 607 can drive the test plate 609 to displace, so that the test plate 609 is in the state of adhesion with the extension end of the cylinder body 403, when the test plate 609 adhesion with the outer wall of the cylinder body 403 displaces, the ball 610 will adhesion with the outer wall of the cylinder body 403 and rotate, through the rolling of the ball 610, the friction can be reduced, so that the wear of the cylinder body 403 in the detection process can be reduced, when the test plate 609 changes position and is in the stepped position of the output end of the cylinder body 403, at this time the position change of the test plate 609 will cause the position change of the side plate 605, the displacement of the side plate 605 will cause the synchronous displacement of the laser displacement sensor 606, at this time the laser displacement sensor 606 receives the displacement signal, which means that the test position of the test plate 609 has completed adjustment, at this time the laser displacement sensor 606 can control the motor 503 to stop running, at this time the test plate 609 on both sides is in the state of clamping the single-stage output end of the cylinder body 403, after the test plate 609 completes the automatic position adjustment, the hydraulic rod 3 is started to extend, after the hydraulic rod 3 runs, it can push the bearing plate 401 to move upwards, at this time, since the lower end of the cylinder body 403 is fixed with the bearing plate 401 and the upper end is in contact with the test plate 609, and the test plate 609 is in a fixed height state, the upward movement of the bearing plate 401 can exert pressure on the cylinder body 403, if the cylinder body 403 can bear the predetermined pressure without failure, it means that the cylinder body 403 is qualified, and the single-stage pressure test of the cylinder body 403 is completed, then the motor 503 is started again, after the motor 503 runs, it can drive the test plate 609 to continue to move upwards, the test plate 609 can automatically position the next output end position of the cylinder body 403 in the process of moving upwards, after positioning, the hydraulic rod 3 is controlled to further test the cylinder body 403, for multi-stage hydraulic cylinders, the automatic positioning and detection operation of multiple positions can be realized, which has strong automation capability and effectively improves the detection efficiency.By applying pressure to the pressing plate 706 after moving down the stabilizing plate 710, a certain pressure can be applied to the oil cylinder body 403 from above, and when the hydraulic rod 3 operates to press the oil cylinder body 403, the pressure received by the test plate 609 can be shared, avoiding the test plate 609 from being broken after being pressed, and improving the stability of the positioning assembly 6 structure during the test process.
