[0026] Specifically, the double-sided rack 10 moves forward by pushing the first electric telescopic rod 9, and the teeth of the double-sided rack 10 mesh with the two gears 25, so that the two gears 25 rotate. Since the two gears 25 mesh with the sliding rack 14, the sliding rack 14 moves, driving the connecting rod 13 and the clamping block 11 to move, thereby clamping the pressure gauge housing. This clamping method is adaptive and can adapt to pressure gauge housings of different sizes. In addition, the cooperation of the first electric telescopic rod 9, the gear 25 and the sliding rack 14 can achieve precise and stable clamping, ensuring stability and accuracy during the processing.

[0027] Reference Figure 1 and Figure 3 The cleaning mechanism includes a water tank 21, which is fixedly connected to the top of the second platform 8. A water pump 20 is fixedly connected to one side of the water tank 21. A water pipe is fixedly connected to the top of the water pump 20. A hose 19 is fixedly connected to the top of the water pipe. One end of the hose 19 is detachably connected to a water inlet pipe 18. One end of the water inlet pipe 18 is fixedly connected to a sprinkler 26. The outer wall of the sprinkler 26 is fixedly connected to a water outlet pipe 17.

[0028] Specifically, during the processing, the water pump 20 draws clean water from the water tank 21 and transports it to the water sprayer 26 through the hose 19. The water sprayer 26 sprays the water onto the inner wall of the pressure gauge housing through the water outlet pipe 17 to clean the impurities and residues on the inner wall of the pressure gauge.

[0029] Reference Figure 2 and Figure 3A through hole 12 is opened on the surface of the first platform 1, and the sprinkler 26 is located below the through hole 12. A second electric telescopic rod 15 is fixedly connected to the top of the second platform 8, and a water receiving box 16 is installed at the output end of the second electric telescopic rod 15. The sprinkler 26 is fixedly connected to the inside of the water receiving box 16 through a cylinder.

[0030] Specifically, the second electric telescopic rod 15 pushes the water sprayer 26 through the through hole 12 to flush the pressure gauge housing, and water is sprayed from the water outlet pipe 17 to clean the inside of the pressure gauge housing. The sewage generated by the cleaning passes through the through hole 12 and falls into the water receiving box 16.

[0031] Reference Figure 1 and Figure 4 A first motor 2 is fixedly connected to the bottom of the first platform 1, a threaded rod 3 is fixedly connected to the output end of the first motor 2, a lifting plate 5 is threadedly connected to the outer wall of the threaded rod 3, one end of the lifting plate 5 is slidably connected to a vertical plate 4, the bottom of the vertical plate 4 is fixedly connected to the upper surface of the first platform 1, a second motor 6 is fixedly connected to the top of the lifting plate 5, a fixing column 7 is fixedly connected to the output end of the second motor 6, a first mounting plate 22 is fixedly connected to the bottom of the fixing column 7, a second mounting plate 23 is installed at the bottom of the first mounting plate 22, the first mounting plate 22 and the second mounting plate 23 are fixedly connected by bolts, and a thread cutter 24 is fixedly connected to the bottom of the second mounting plate 23.

[0032] Specifically, by controlling the rotation of the first motor 2, the threaded rod 3 can be driven to rotate, thereby driving the lifting plate 5 to move up and down along the vertical plate 4. By controlling the rotation of the second motor 6, the fixed column 7 can be driven to rotate, and the thread cutter 24 can be further rotated to realize the internal thread processing of the pressure gauge housing. The first mounting plate 22 and the second mounting plate 23 are fixedly connected by bolts, which facilitates the disassembly of the thread cutter 24.

[0033] Working principle: When using the device, first place the pressure gauge housing in the middle of the clamping block 11, then start the first electric telescopic rod 9 to push it forward, and the double-sided rack 10 moves forward accordingly, meshing with the two gears 25 to rotate the gear 25. Since the gear 25 meshes with the sliding rack 14, the sliding rack 14 will move, thereby driving the connecting rod 13 and the clamping block 11 to move, thereby realizing adaptive clamping of pressure gauge housings of different sizes. After the clamping is completed, start the first motor 2 to drive the threaded rod 3 to rotate, so that the lifting plate 5 moves up and down along the vertical plate 4 to a suitable position, then start the second motor 6 to drive the fixed column 7 to rotate, thereby driving the thread cutter 24 to rotate, and start to perform internal threading on the pressure gauge housing. During the processing, the second electric telescopic rod 15 pushes the sprinkler 26 to pass through the through hole 12 to flush the pressure gauge housing, and the water pump 20 is started to draw clean water from the water tank 21 and transport it to the sprinkler 26 through the hose 19. The sprinkler 26 sprays water onto the inner wall of the pressure gauge housing through the outlet pipe 17 to clean the impurities and residues on the inner wall of the pressure gauge. The sewage generated by the cleaning passes through the through hole 12 and falls into the water receiving box 16 to collect and treat the wastewater. After the processing is completed, the lifting plate 5 and the thread cutter 24 are moved back to their original positions by controlling the reverse rotation of the first motor 2 and the second motor 6, and then the clamping block 11 is retracted through the first electric telescopic rod 9 to take out the processed pressure gauge housing.
