[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0033] Example 1:

[0034] like Figure 1—4 shows: a sealing ring performance detection device, including a workbench 1, on which a controller 2, a sleeve base 3 and a lifting drive assembly 6 are installed, and the lifting drive assembly 6 includes a top frame 64, which is installed at the top of a light rod 63 and a lead screw 61, and a drive motor 62 is installed on the top frame 64, and the drive motor 62 drives the connecting lead screw 61, and the lead screw 61 and the light rod 63 are installed on the workbench 1, and a stroke limit assembly 5 is installed on the light rod 63, and the lead screw 61 is threadedly connected to the lifting plate 4, and the lifting plate 4 is slidably connected to the light rod 63, and a sealing ring mounting rod 7 is installed on the bottom surface of the lifting plate 4, and the sleeve base 3 is arranged vertically below the sealing ring mounting rod 7, and the sealing ring mounting rod 7 is in the middle. The rod body 72 is adapted to be inserted into the sleeve 31 in the sleeve base 3, and the outer side surface of the rod body 72 is provided with an annular groove adapted to be embedded with an O-ring 73. The bottom surface of the workbench 1 inside the sleeve 31 is connected to one end of the three-way pipe 81 in the pressurizing component 8, and the other two ends of the three-way pipe 81 are respectively installed with a pressure transmitter 83 and a solenoid valve 82. The air inlet end of the solenoid valve 82 is connected to a compressed air pipeline. By integrating the sleeve base, the lifting drive component and the pressurizing component, a fully automated process of sealing ring installation, pressurization, pressure maintenance and performance evaluation is realized, which not only significantly improves the detection efficiency and accuracy, but also reduces the interference of human factors. The screw 61 is rotatably mounted on the workbench 1, and the axis of the screw 61 is parallel to the axis of the light rod 63. Driven by the motor 62, the lead screw 61 rotates stably, so that the lifting plate 4 generates a spiral pair motion with the lead screw 61 under the limit of the light rod 63, and then moves up and down stably. The number of the travel limit components 5 is two and they are respectively arranged on the upper and lower sides of the lifting plate 4. The travel limit component 5 includes a pipe clamp 51, which is clamped on the outer side of the light rod 63. The side of the pipe clamp 51 is connected to a connecting plate 52, and a travel switch 53 is installed on the end surface of the connecting plate 52 facing the lifting plate 4. The travel switch 53 is electrically connected to the relay in the controller 2, and the controller 2 is electrically connected to the driving motor 62. When the lifting plate 4 touches the contacts of the travel switch 53 in the travel limit components 5 on the upper and lower sides, the controller 2 automatically controls the driving The motor 62 stops rotating to realize the limit control of the upper and lower positions. The pressure transmitter 83 is electrically connected to the single chip microcomputer in the controller 2. The controller 2 is electrically connected to the solenoid valve 82 and the speaker. When the pressure transmitter 83 detects that the pressure in the pipeline reaches the set threshold, the valve path of the solenoid valve 82 is closed to maintain the pressure. After the pressure loss is greater than the set threshold within the set time, the speaker sounds an alarm to realize accurate and automated detection of the sealing performance of the O-ring 73. The rod body 72 is threadedly connected to the screw rod 71. The top of the screw rod 71 is connected to the lifting plate 4. The operator can quickly load and unload rod bodies 72 of different specifications on the screw rod 71 to install and detect O-rings 73 of different specifications. The bottom end of the sleeve 31 is connected to the flange 32.The flange 32 is fixed to the workbench 1 by bolts. The operator can quickly replace the sleeve base 3 of different specifications on the workbench 1 to test the O-rings 73 of different specifications. A sealing gasket 33 is sandwiched between the flange 32 and the workbench 1. The sealing gasket 33 plays an effective sealing role and ensures the sealing of the connection between the sleeve base 3 and the workbench 1.

[0035] The working principle of this technical solution is as follows: in the initial state, the top surface of the lifting plate 4 touches the contact of the travel switch 53 located on the upper side of the lifting plate 4. At this time, the operator puts the O-ring 73 to be tested into the annular groove provided on the rod body 72, and then automatically detects the device through the controller 2; after the detection starts, the drive motor 62 runs to drive the screw 61 to rotate, and then the lifting plate 4 moves to the lower side of the screw 61 under the limit guide of the light rod 63, and then drives the rod body 72 to insert into the inner side of the sleeve 31, so that the O-ring 73 and the sleeve 31 have an interference fit, and then the valve path of the solenoid valve 82 is opened, and compressed air enters the inner side of the sleeve 31 below the O-ring 73 through the three-way pipe 81. When the pressure transmitter 83 detects that the pressure in the pipeline reaches the set threshold, the valve path of the solenoid valve 82 is closed to maintain the pressure. By feeding back the pressure loss within the set time, the sealing performance of the O-ring 73 can be accurately and automatically detected.
