[0038] A first torsion spring is arranged between the sealing rotating plate 163 and the numerical control case 1, and the sealing rotating plate 163 is reset by the elastic force of the first torsion spring. A second spring is arranged between the fixed frame 167 and the filter plate 168, and the filter plate 168 is reset by the elastic force of the second spring.

[0039] When the embodiment works: the sliding rod 161 is driven to move upwards by the upward movement of the rotating clamping table 6, the sliding rod 161 moves upwards to drive the fixed plate 162 to move upwards, the fixed plate 162 moves upwards to drive the short plate 164 to rotate upwards, the short plate 164 rotates upwards to drive the sealing rotating plate 163 to rotate downwards, and the cutting fluid and iron filings sprayed during machining flow into the collection base 2 through the downward rotation of the sealing rotating plate 163, preventing the cutting fluid and impurities from accumulating inside the numerical control case 1 and affecting the subsequent machining effect. At the same time, after machining is completed, the sealing rotating plate 163 is reset, preventing the peculiar smell of the cutting fluid in the collection base 2 from overflowing and affecting the use of the operator;

[0040] At the same time, the filter plate 168 separates the cutting fluid and iron filings, the connecting plate 165 moves upwards when the fixed plate 162 moves upwards, the connecting plate 165 moves upwards to drive the long plate 166 and the pulley frame 169 to move upwards, the pulley frame 169 moves upwards to contact the toothed plate 1610, the toothed plate 1610 moves back and forth during the upward movement of the pulley frame 169, the toothed plate 1610 moves back and forth to drive the filter plate 168 to move back and forth, and the iron filings accumulated at the bottom of the sealing rotating plate 163 can be laid flat on the filter plate 168 through the back-and-forth movement of the filter plate 168, preventing the iron filings from accumulating at the bottom of the sealing rotating plate 163 and affecting the subsequent rotation of the sealing rotating plate 163.

[0041] The purification device comprises a fixing seat 171, a push plate 172, a connecting frame 173, a cross plate 174 and a liquid storage tank 175. The fixing seat 171 is fixedly installed at the bottom of the filter plate 168. The push plate 172 is fixedly installed at the bottom of the fixing seat 171. The connecting frame 173 is fixedly installed on the inner wall of the push plate 172. The cross plate 174 is fixedly installed on the surface of the connecting frame 173. The liquid storage tank 175 is fixedly installed on the outer wall of the collecting base 2. The bottom of the liquid storage tank 175 is provided with a connecting pipe. The cutting fluid is prevented from breeding bacteria, deteriorating and darkening in color due to long-term precipitation, so that the cooling and lubricating effect of the recovered cutting fluid is reduced, and the cooling effect is affected.

[0042] The connecting rod 176 is fixedly installed at the bottom of the long plate 166. The pulley seat 177 is fixedly installed on the surface of the connecting rod 176. The circular ring 178 is arranged in the connecting pipe. The sliding rod 179 is slidably penetrated through the surface of the circular ring 178. The sealing circular plate 1710 is fixedly installed at the end of the sliding rod 179 away from the pulley seat 177. The circular plate 1711 is fixedly installed at the end of the sliding rod 179 close to the pulley seat 177. The trapezoidal plate 1712 is fixedly installed on one side of the circular plate 1711 close to the pulley seat 177. The sliding rod 179 and the circular plate 1711 are reset by the elastic force of the third spring.

[0044] The fixing seat 171 is moved back and forth by the to-and-fro movement of the filter plate 168, so as to move the push plate 172 back and forth. The push plate 172 is moved back and forth to move the connecting frame 173 back and forth. The connecting frame 173 is moved back and forth to move the cross plate 174 back and forth. The push plate 172 and the cross plate 174 are moved back and forth in the collecting base 2, so as to prevent the cutting fluid from breeding bacteria, deteriorating and darkening in color due to long-term precipitation, so that the cooling and lubricating effect of the recovered cutting fluid is reduced, and the cooling effect is affected. At the same time, the upward movement of the long plate 166 moves the connecting rod 176 upward. The upward movement of the connecting rod 176 moves the pulley seat 177 upward. The upward movement of the pulley seat 177 moves the trapezoidal plate 1712 toward the connecting pipe. The movement of the trapezoidal plate 1712 toward the connecting pipe seals the connecting pipe by the circular plate 1711.

[0045] At the same time, the circular plate 1711 moves towards the connecting pipe, which drives the slide rod 179 to move away from the circular ring 178. The movement of the slide rod 179 away from the circular ring 178 drives the sealing circular plate 1710 to separate from the sealing of the circular ring 178, so that the ph regulator in the liquid storage tank 175 enters the space between the circular ring 178 and the circular plate 1711. When the pulley seat 177 is reset after the machining is completed, the extrusion of the trapezoidal plate 1712 and the circular plate 1711 is released. The slide rod 179 and the circular plate 1711 are reset by the elastic force of the third spring. The reset of the circular plate 1711 releases the sealing of the connecting pipe, so that the quantitative regulator flows into the collection base 2. The pH regulator can effectively adjust the acidity and alkalinity of the cutting fluid, restore its cooling and lubricating performance, and facilitate recycling.
