[0044] Reference Figure 6 ,the auxiliary component 53 includes a receiving groove 531, and the receiving groove 531 is opened on the side wall of the bearing platform 35 at the end away from the fixed clamping block 34; a switch button 532 is embedded on the bottom wall of the receiving groove 531, and the switch button 532 is electrically connected to the flow solenoid valve 52; a lever 533 is hinged on the side wall of the receiving groove 531 near the fixed clamping block 34, and the lever 533 can completely enter the receiving groove 531; a spring 534 is sleeved on the switch button 532, one end of the spring 534 is fixedly connected to the bottom wall of the receiving groove 531, and the other end of the spring 534 is fixedly connected to the end of the switch button 532 away from the bottom wall of the receiving groove 531.

[0045] During use, the bearing platform 35 moves away from the electro-hydraulic push rod 31 under the action of the movable clamping block 33. When the bearing platform 35 moves to the position where the side wall of the receiving groove 531 coincides with the side wall of the fixed clamping block 34, the bearing platform 35 continues to move, so that the lever 533 enters the receiving groove 531 under the action of the fixed clamping block 34, triggering the switch button 532 and starting the flow solenoid valve 52. At this time, the oil in the distribution ring 44 can flow through the flow solenoid valve 52 and the first bellows 4504 into the electromagnetic directional valve, and the electromagnetic directional valve is tested, avoiding manual intervention. At the same time, the spring 534 is compressed, so that after the experiment is completed, when the electro-hydraulic push rod 31 drives the movable clamping block 33 to move away from the fixed clamping block 34, the receiving groove 531 gradually moves away from the fixed clamping block 34, so that the lever 533 no longer abuts against the fixed clamping block 34. Under the action of the spring 534, the lever 533 can return to the previous state, preparing for the next experiment and being beneficial to improving the detection efficiency.

[0046] Referring to Figure 1 , the protection structure includes a protective cover 61. The protective cover 61 is a hollow cylinder with one end open. The protective cover 61 opens downward and is fixedly installed on the turntable 2. The protective cover 61 is coaxially arranged with the turntable 2. Six operation windows 62 are evenly distributed and opened at one end of the protective cover 61 away from the base 1. The operation windows 62 are in the vertical direction of the fixed clamping block 34, and the operation windows 62 correspond to the fixed clamping blocks 34 one by one. Six protective doors 63 are slidably installed at one end of the protective cover 61 away from the base 1. The protective doors 63 correspond to the operation windows 62 one by one, and the protective doors 63 can completely cover the operation windows 62.

[0047] Referring to Figure 1 , the protection structure further includes six telescopic rods 64. The fixed ends of the six telescopic rods 64 are fixedly installed at one end of the protective cover 61 away from the base 1. The movable ends of the telescopic rods 64 correspond to and are fixedly connected to the protective doors 63. The moving direction of the movable ends of the telescopic rods 64 is the same as the sliding direction of the protective doors 63. The rodless cavity of the electro-hydraulic push rod 31 communicates with the rodless cavity of the telescopic rod 64.

[0048] When the electro-hydraulic push rod 31 pushes the movable clamping block 33 towards the fixed clamping block 34 to clamp the electromagnetic directional valve, the air in the rod chamber of the electro-hydraulic push rod 31 enters the rodless cavity of the telescopic rod 64, causing the movable end of the telescopic rod 64 to extend and driving the protective door 63 to slide, covering the operation window 62, avoiding the oil leakage and spraying during the test of the electromagnetic directional valve, and affecting the working area environment.

[0049] Referring to Figure 1 , the turntable 2 is connected with a driving mechanism 7. The driving mechanism 7 includes a motor 71. The motor 71 is fixedly installed on the upper layer of the base 1. The motor 71 is electrically connected to the controller 51. A belt pulley 72 is coaxially and fixedly installed at the output end of the motor 71. A belt 73 is wound around the belt pulley 72 and the side wall of the turntable 2 together.

[0050] During use, the controller 51 controls the motor 71 to start. The motor 71 drives the belt pulley 72 to rotate. The rotation of the belt pulley 72 causes the belt 73 to move and drives the turntable 2 to rotate, realizing the position switching between the six stations on the turntable 2, which is beneficial to improving the detection efficiency.

[0051] The implementation principle of a full-automatic test bench for detecting electromagnetic reversing valves in the embodiments of the present application is as follows: When in use, an operator places the electromagnetic reversing valve on the carrier table 35, adjusts the positions of the first slider 4502 and the second slider 4505 so that the quick-change joint 4514 connected to the first liquid path 4503 is communicated with the liquid inlet of the electromagnetic reversing valve, and the quick-change joint 4514 connected to the second liquid path 4506 is communicated with the liquid outlet of the electromagnetic reversing valve; adjusts the positions of the third slider 4509 and the fourth slider 4511 so that the quick-change joint 4514 connected to the third liquid path 4510 and the quick-change joint 4514 connected to the fourth liquid path 4512 are coaxial with the two reversing ports of the electromagnetic reversing valve. Then operate the controller 51 to make the electro-hydraulic push rod 31 and the oil pump 42 run. The electro-hydraulic push rod 31 moves the movable clamping block 33 in the direction close to the fixed clamping block 34. At the same time, the movable clamping block 33 pushes the carrier table 35 to move until the electromagnetic reversing valve is clamped. At this time, the quick-change joint 4514 connected to the third liquid path 4510 and the quick-change joint 4514 connected to the fourth liquid path 4512 are communicated with the two reversing ports of the electromagnetic reversing valve. During this period, the shift lever 533 enters the storage groove 531 under the action of the fixed clamping block 34, so that the switch button 532 is triggered and the flow solenoid valve 52 is started. The oil in the distribution ring 44 can flow through the flow solenoid valve 52 and the first bellows 4504 into the electromagnetic reversing valve to conduct an experiment on the electromagnetic reversing valve. During this process, the clamping of the electromagnetic reversing valve and the start and stop of the flow solenoid valve 52 avoid manual intervention, significantly improving the detection efficiency.

[0052] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
