[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The embodiment of this application is as follows:

[0019] Please see Figures 1-3 , Figure 1This is a schematic diagram of the overall structure of the mechanical seal testing fixture of this utility model. Figure 2 This is a structural schematic diagram of the stabilizing component of this utility model. Figure 3 This is a schematic diagram of the structure of the first buffer pad 113 and the second buffer pad 114 of this utility model.

[0020] This utility model discloses a mechanical seal testing fixture, comprising a worktable 101, a positioning plate 102, a support frame 103, a positioning cavity 104, a mounting plate 105, a drive cylinder 106, a push plate 107, a positioning arc plate 108, an infrared sensor 109, a positioning block 110, a fixed base 111, a telescopic rod 112, a first buffer pad 113, and a second buffer pad 114. It solves the problem in existing technologies where each mechanical seal requires screwing, which, in batch testing scenarios, causes operator fatigue due to continuous screwing, increases worker workload, and affects work quality and efficiency. It is understood that the aforementioned solution can also be used to reduce the labor intensity of employees.

[0021] In this embodiment, the workbench 101, the positioning disk 102, the support frame 103, and the positioning cavity 104 are all existing technologies. The bottom of the workbench 101 is equipped with a driving device that can drive the positioning disk 102 to rotate. The support frame 103 is equipped with a cylinder, a sealing head, a pneumatic pump, etc. The positioning disk 102 is equipped with a pressure gauge, which can be used to perform sealing tests on mechanical seals. The specific structure refers to the existing technology CN220366969U, a mechanical seal testing device. Through the positioning component, the problem of existing technologies where each mechanical seal requires screwing to be positioned, causing operator fatigue and increasing the workload of workers in batch testing scenarios, is solved.

[0022] The mounting plate 105 is fixedly connected to the support frame 103 and is located on the side of the support frame 103 near the positioning disk 102. The drive cylinder 106 is fixedly connected to the mounting plate 105 and is located on the side of the mounting plate 105 near the positioning disk 102. The push plate 107 is fixedly connected to the output end of the drive cylinder 106. The detection component detects the position of the positioning cavity 104. The stabilizing component is installed on the mounting plate 105. The mounting plate 105 is fixedly installed on the support frame 103 to provide installation conditions for the drive cylinder 106. The drive cylinder 106 is horizontally installed on the mounting plate 105 with its output end facing the positioning disk 102. The push plate 107 is arc-shaped and is driven by the drive cylinder 106. The telescopic mechanism allows the push plate 107 to move, and the detection component can detect the position of the positioning cavity 104. When the positioning cavity 104 reaches the designated position, the drive cylinder 106 can then actuate to push the push plate 107, ensuring that the push plate 107 can accurately push the mechanical seal within the positioning cavity 104. The stabilizing component enhances the stability of the push plate 107. By driving the push plate 107 to move through the drive cylinder 106, the mechanical seal is positioned and fixed, avoiding manual operation. This solves the problem in the prior art where each mechanical seal requires screwing, which, in batch testing scenarios, causes operator fatigue due to continuous screwing, increases the workload of workers, and affects work quality and efficiency.

[0023] Secondly, the positioning arc plate 108 is fixedly connected to the positioning disk 102 and is located on the side of the positioning disk 102 near the positioning cavity 104. The positioning arc plate 108 is an arc-shaped plate, and the number of them is the same as the number of positioning cavities 104. The positioning arc plate 108 is installed on the top of the positioning disk 102, close to the opening of the positioning cavity 104. Through the positioning arc plate 108, the mechanical seal can be prevented from being pushed out of the positioning cavity 104 by the push plate 107.

[0024] Meanwhile, the infrared sensor 109 is fixedly connected to the support frame 103 and located on the side of the support frame 103 near the drive cylinder 106; the positioning block 110 is fixedly connected to the positioning arc plate 108 and located on the top of the positioning arc plate 108. The number of positioning blocks 110 is the same as the number of positioning arc plates 108. Multiple positioning blocks 110 are respectively installed at the top center of multiple positioning arc plates 108. The infrared sensor 109 consists of an infrared emitting device and a receiving device. The emitting device actively emits an infrared beam. When the infrared light encounters the positioning plate, it will be reflected. The receiving device receives the reflected infrared signal. By analyzing and processing the signal, the position of the positioning cavity groove 104 on the positioning disk 102 can be determined. Through the detection component, the position of the positioning cavity groove 104 can be detected.

[0025] In addition, the fixed base 111 is fixedly connected to the mounting plate 105 and is located on the side of the mounting plate 105 near the push plate 107; the two ends of the telescopic rod 112 are fixedly connected to the fixed base 111 and the push plate 107 respectively. The fixed base 111 is used to support the telescopic rod 112. The telescopic end of the telescopic rod 112 extends and retracts with the movement of the push plate 107. Through the telescopic rod 112, the stability of the push plate 107 can be improved and the possibility of the push plate 107 shifting can be reduced.

[0026] Finally, the first buffer pad 113 is disposed on the positioning arc plate 108; the second buffer pad 114 is disposed on the push plate 107. Both the first buffer pad 113 and the second buffer pad 114 are made of rubber. The first buffer pad 113 is embedded in the inner arc surface of the positioning arc plate 108, and the second buffer pad 114 is embedded in the inner arc surface of the push plate 107. Through the first buffer pad 113 and the second buffer pad 114, a buffering effect can be achieved when positioning the mechanical seal.

[0027] In this embodiment, during use, the mechanical seal is placed in the positioning cavity 104 of the positioning disk 102. The positioning disk 102 rotates to transport the mechanical seal. During the rotation of the positioning disk 102, when the positioning block 110 aligns with the infrared sensor 109, the infrared light emitted by the infrared sensor 109 is reflected back by the positioning block 110. The infrared sensor 109 receives the reflected infrared signal and, through signal analysis and processing, determines that the positioning cavity 104 on the positioning disk 102 has reached the designated position. Then, the external control unit controls the drive cylinder 106 to extend, driving the push plate 107 to move towards the mechanical seal until the push plate 107... The mechanical seal is pressed against the positioning cavity 104 to fix the mechanical seal in place. Then, the sealing head on the support frame 103 moves downward and contacts the end of the mechanical seal. The air pump supplies air to the sealing head through the air pressure hose. The air pressure gauge on the sealing tube is observed to test the mechanical seal performance. After the test is completed, the drive cylinder 106 retracts, driving the push plate 107 to reset. At the same time, the sealing head rises and resets. The positioning disk 102 continues to rotate to test the next mechanical seal. During the test, the positioning arc plate 108 can effectively prevent the mechanical seal from being pushed out of the positioning cavity 104 by the push plate 107. At the same time, the first buffer pad 113 and the second buffer pad 114 can act as a buffer to protect the mechanical seal. The push plate 107 is moved by the drive cylinder 106 to position and fix the mechanical seal, avoiding manual operation. This solves the problem in the prior art that the positioning of each mechanical seal requires turning the screw, which causes operator fatigue and increases the workload of workers in batch testing scenarios, affecting work quality and efficiency.
