A pressing component 3 is also provided on the lifting frame 43. The pressing component 3 is used to press the switch to be detected. The lifting driving mechanism 41 can be a cylinder. The support housing 21 of the switch clamping device 2 is installed above the working platform 1. The clamping mechanism 22 moves in the chute in the X direction and clamps the switch. The positioning mechanism 23 fixes its relative position. The support frame 42 of the lifting device 4 supports the lifting frame 43 above the working platform 1. The lifting driving mechanism 41 drives the lifting frame 43 to lift and lower, and the pressing component 3 presses the switch accordingly, simulating the usage process of the switch to test its lifespan.

[0022] The clamping mechanism 22 includes: a fixing plate 221, an adjusting plate 222, a left clamping block 223, and a right clamping block 224. Both the fixing plate 221 and the adjusting plate 222 are located in the chute. The fixing plate 221 is located above the adjusting plate 222. The fixing plate 221 is fixedly connected to the support housing 21. The adjusting plate 222 can slide relative to the fixing plate 221 in the X direction. The left clamping plate is connected to the fixing plate 221, and the right clamping plate is connected to the adjusting plate 222.

[0023] The positioning mechanism 23 includes: a screw rod 231, a positioning block 232 and a positioning component 233. The screw rod 231 is threadedly connected to the support housing 21. The lower end of the screw rod 231 is connected to the positioning block 232. The screw rod 231 can rotate relative to the positioning block 232. The positioning block 232 can move up and down relative to the fixed plate 221, and the positioning block 232 cannot rotate relative to the fixed plate 221. A positioning component 233 is provided at the lower end of the positioning block 232. The positioning block 232 passes through the fixed plate 221 and can position the adjusting plate 222 through the positioning component 233. During use, the screw rod 231 is rotated. Under the action of the thread of the support housing 21, the screw rod 231 drives the positioning block 232 to move up and down. The positioning component 233 at the lower end of the positioning block 232 passes through the fixed plate 221 to fix the position of the adjusting plate 222, realizing the positioning of the relative position between the clamping mechanism 22 and the support housing 21.

[0024] The positioning component 233 includes: positioning convex parts 2331, positioning teeth (not shown in the figure) and a rack 2332.

During use, when the positioning mechanism 23 works, the screw rod 231 is rotated to drive the positioning block 232 to move up and down, and the positioning convex parts 2331 on the positioning block 232 move accordingly. When the positioning teeth of the positioning convex parts 2331 mesh with the racks 2332 in the positioning groove 2221 of the adjusting plate 222, through the interaction between the positioning teeth and the racks 2332, the position of the adjusting plate 222 is fixed, thereby realizing the positioning of the relative position between the clamping mechanism 22 and the support housing 21 and ensuring stable clamping.

During use, the lifting drive mechanism 41 drives the lifting frame 43 to move up and down at the movable connection of the lifting rod 421 and the sleeve 422, realizing the pressing action of the pressing component 3 on the switch.

[0026] A sliding groove 431 is formed on the lifting frame 43. The sliding groove 431 is of a strip structure. The pressing component 3 is located in the sliding groove 431, and the pressing component 3 can move relative to the lifting frame 43 in the X direction along the sliding groove 431. When the clamping device clamps switches of different sizes, due to the different diameters of the switches, there are differences in the clamping distances, that is, the position of the pressing component 3 in the sliding groove 431 is adjusted to ensure that the pressing component 3 can accurately press the switch below.

[0027] The pressing-down component 3 includes: a test pressing rod 31 which passes through the sliding groove 431. A nut 32 is threadedly connected to the test pressing rod 31. The test pressing rod 31 is further provided with a pressing ring 33. The cooperation between the nut 32 and the pressing ring 33 can clamp the lifting frame 43. During use, when adjusting the test pressing rod 31 to align it with the switch, rotate the nut 32 to clamp the lifting frame 43 with the nut 32 and the pressing ring 33, preventing deviation during the pressing test of the test pressing rod 31 and resulting in errors in data testing.

[0028] Arc-shaped surfaces are relatively provided on the left fixing plate 221 and the right fixing plate 221, and the arc-shaped surfaces correspond to the radian of the side surface of the switch to be detected. The arc-shaped surfaces can better fit the arc-shaped side surface of the switch, thereby clamping the switch more stably and ensuring the accuracy of the test.

[0029] A monitoring display 5 and a control box 6 are further provided on the working platform 1. The data input end of the monitoring display 5 is connected to the data output end of the control box 6. The input end of the control box 6 is electrically connected to the switch to be detected through a data line. During use, the control box 6 controls the lifting device 4 to drive the pressing-down component 3 to press the switch, and simultaneously monitors the change of the electrical signal of the switch. The monitoring display 5 real-time displays the number of presses and the switch status until the switch fails, completing the life test.
