[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses a clamp to clamp and fix the turbine shaft that needs deburring. Then, the first electric telescopic rod is controlled to extend, so that the bottom of the turbine shaft moves into the through-hole. Then, the second electric telescopic rod is controlled to extend, so that the grinding stone can come into contact with the turbine shaft. Then, the motor is turned on, so that the turbine shaft can be rotated. Then, the first electric telescopic rod is controlled to slowly extend, so as to deburr the turbine shaft. The grinding pressure is monitored in real time by a pressure sensor and the data is fed back to the PLC controller, which then adjusts the extension and retraction of the second electric telescopic rod to precisely control the contact pressure between the grinding stone and the turbine shaft. This ensures the deburring effect while avoiding over-grinding and damage to the turbine shaft. When the electromagnet is energized, it attracts an iron block to fix the grinding stone. The grinding stone can be quickly replaced after the power is turned off, improving processing efficiency.

[0012] 2. This utility model uses a fan that can generate suction when powered on, thereby creating negative pressure inside the dust collection box.

A clamp 12 is fixedly connected to the output shaft of the motor 11. A through-hole 5 is opened in the middle of the worktable 3. Grooves 15 are opened on both the left and right sides of the inner cavity of the through-hole 5. A second electric telescopic rod 16 is fixedly connected to the inner cavity of the groove 15. A mounting base 20 is fixedly connected to the other end of the second electric telescopic rod 16. A slot 21 is opened on the other side of the mounting base 20. An electromagnet 23 is fixedly connected to the inner cavity of the slot 21. An iron block 24 is provided on one side of the polishing stone 18. The electromagnet 23 is fixedly connected to the iron block 24 by magnetic force. A pressure sensor 22 is provided between the second electric telescopic rod 16 and the mounting base 20.

[0021] This technical solution uses clamp 12 to clamp and fix the turbine shaft that needs deburring. Then, the first electric telescopic rod 7 is extended to move the bottom of the turbine shaft into the opening 5. Then, the second electric telescopic rod 16 is extended to bring the polishing stone 18 into contact with the turbine shaft. Then, the motor 11 is turned on to rotate the turbine shaft. The first electric telescopic rod 7 is then slowly extended to deburr the turbine shaft. The pressure sensor 22 monitors the polishing pressure in real time and feeds the data back to the PLC controller 9, which then adjusts the extension of the second electric telescopic rod 16 to precisely control the contact pressure between the polishing stone 18 and the turbine shaft. This ensures the deburring effect while avoiding over-polishing and damage to the turbine shaft. When the electromagnet 23 is energized, it attracts the iron block 24 to fix the polishing stone 18.

[0022] Based on Embodiment 1, this utility model is as follows: Figure 1-4 As shown, a suction hood 2 is fixedly connected to the top of the base plate 1 via a bracket. A dust collection box 8 is fixedly connected to the right end of the top of the base plate 1. A fan 19 is fixedly connected to the top of the dust collection box 8. The suction port of the fan 19 is fixedly connected to the top of the inner cavity of the dust collection box 8 via a pipe. A filter screen 13 is provided in the upper part of the inner cavity of the dust collection box 8. A connecting pipe 14 is fixedly connected to the left side of the dust collection box 8. The other end of the connecting pipe 14 is fixedly connected to the suction hood 2. A drain port is provided on the right side of the inner cavity of the dust collection box 8. A baffle is provided. A battery box 4 is fixedly connected to the top left end of the base plate 1. A storage battery 17 is fixedly connected to the inner cavity of the battery box 4. A display 10 is fixedly connected to the left end of the front of the workbench 3. The input terminal of the display 10 is electrically connected to the output terminal of the pressure sensor 22.

The output terminal of the PLC controller 9 is electrically connected to the input terminals of the first electric telescopic rod 7, the motor 11, the second electric telescopic rod 16, the fan 19, and the electromagnet 23.

[0023] This technical solution uses a blower 19 to generate suction when powered on, which can create a negative pressure inside the dust collection box 8. Under the action of the connecting pipe 14, the suction hood 2 can also generate suction, which can suck away the dust generated during the deburring process and send it into the dust collection box 8. The filter screen 13 can be used to filter the dust and prevent it from entering the blower 19.

[0024] The working principle of this utility model is as follows: The turbine shaft requiring deburring is clamped and fixed using the clamp 12. Then, the first electric telescopic rod 7 is extended, moving the bottom of the turbine shaft into the opening 5. Next, the second electric telescopic rod 16 is extended, causing the polishing stone 18 to contact the turbine shaft. The motor 11 is then turned on, causing the turbine shaft to rotate. The first electric telescopic rod 7 is then slowly extended, deburring the turbine shaft. The pressure sensor 22 monitors the polishing pressure in real time and feeds the data back to the PLC controller 9, which then adjusts the extension and retraction of the second electric telescopic rod 16. The contact pressure between the polishing stone 18 and the turbine shaft is precisely controlled to ensure deburring effect while avoiding excessive polishing that could damage the turbine shaft. The electromagnet 23 is energized to attract the iron block 24, thus fixing the polishing stone 18. The polishing stone 18 can be quickly replaced after power is cut off, improving processing efficiency. The blower 19 is energized to generate suction, which creates negative pressure in the dust collection box 8. Under the action of the connecting pipe 14, the suction hood 2 generates suction, which can suck away the dust generated during the deburring process and send it into the dust collection box 8. The filter screen 13 can filter the dust to prevent it from entering the blower 19.
