[0025] The connecting plate 51 can avoid the electric shaft sleeve 52 and other components from tilting after being installed by polishing the upper and lower layers. The electric shaft contained in the electric shaft sleeve 52 can provide corresponding operating energy to the high-speed fan of the dehumidification end 55, and then the dehumidification end 55 can quickly dry the water molecules on the surface of the component through the high-speed fan. The sealing cover 53 can be firmly installed on the upper end of the electric shaft sleeve 52 by means of the threaded pattern to seal the electric shaft sleeve 52. The through groove 54 can adapt to the shape of the component by means of the circular shape and vertical development.

[0026] Among them, the surface of the dehumidification end 55 is newly provided with a rigid ring 551, a slot 552, a fixing piece, a limiting ring 554, and a waterproof net 555. The inner layer of the rigid ring 551 is developed with a slot 552, and the fixing piece matches the slot 552. The edge of the limiting ring 554 is connected to the fixing piece and is connected to the rigid ring 551 through the fixing piece and the slot 552 and is at the same center point. The waterproof net 555 is embedded in the inner layer area of ​​the limiting ring 554 and is at the same center point. The fixing part is positioned at the inner wall area of ​​the electric shaft sleeve 52 and communicated with the through groove 54 through the rigid ring 551 and the limiting ring 554. The waterproof net 555 covers the surface of the dehumidification end 55 through the limiting ring 554. The rigid ring 551 is made of stainless steel metal and is superimposed with a carbon steel ring. The number of the slots 552 and the fixing parts are both six groups. The fixing parts are arranged in a circular position at the edge of the limiting ring 554. The waterproof net 555 is made of stainless steel metal.

[0027] The rigid ring 551 can improve the origin fixation of the slot 552 due to its anti-rust and high hardness properties, so that the slot 552 can be connected to the fixing part at an accurate position, and then the slot 552 and the fixing part can ensure that the limit ring 554 and the rigid ring 551 are maintained at the same center point through the six groups of annular orientation arrangements. The slot 552 is a concave circular shape, and the two ends of the fixing part 553 are semicircular. The fixing part 553 can be embedded in the center area of ​​the slot 552 through the semicircular shape, and the two can form a stable snap connection through the internal buckle and the block. The waterproof net 555 can avoid rust caused by continuous contact with water molecules and block the gap area through the anti-rust shape.

[0028] The fixing member is provided with a positioning wheel 556, a rotating ring 557, a vertical column 553, an overlap gasket 558, a magnetic block 559, and a buckle 560. The edge of the positioning wheel 556 contacts the rotating ring 557. The vertical column 553 is welded to the edge of the rotating ring 557. The overlap gasket 558 is arranged on the top of the vertical column 553. The magnetic block 559 is embedded in the overlap gasket 558 and is at the same center point. The buckle 560 runs through the center area of ​​the magnetic block 559 and the overlap gasket 558 and the edge is fixedly connected to the magnetic block 559. The positioning wheel 556 is embedded in the edge of the limiting ring 554. The diameter of the rotating ring 557 is smaller than that of the rotating ring 557. The rotating ring 557 and the vertical column 553 form an integrated shape. The overlapping gasket 558 and the magnetic block 559 are both circular in shape, and the buckle 560 is a semicircular solid shape. The overlapping gasket 558 is made of metal. Through its adsorbable characteristics, the magnetic block 559 can fall in parallel for adsorption, thereby completing the installation of the magnetic block 559 and the overlapping gasket 558. The buckle 560 is directly embedded in the center area of ​​the magnetic block 559, so that the overlapping gasket 558 can carry the magnetic block 559 and the buckle 560 to be embedded in the slot 552, so that the buckle 560 can be engaged, inserted, and connected with the internal block of the slot 552.

[0029] The positioning wheel 556 can allow the rotating ring 557 to be completely inserted due to its own diameter, and then the rotating ring 557 can be rotated through the positioning wheel 556. The integrated form of the rotating ring 557 and the vertical column 553 can improve the control stability of the overlapping gasket 558, the magnetic block 559, and the buckle 560. The overlapping gasket 558 and the magnetic block 559 can adapt to the shape of the component due to their circular shape, and the buckle 560 can be easily embedded and subsequently disassembled and detached due to its semi-circular solid shape.

[0030] Among them, the positioning wheel 556 is provided with a limiting plate 1 5561, a solid column 5562, a limiting plate 2 5563, a threaded groove 5564, and a small bolt 5565. The limiting plate 1 5561 is arranged at the lower end of the solid column 5562, the limiting plate 2 5563 is fixedly connected to the upper end of the solid column 5562 and is on the same vertical center line with the limiting plate 1 5561, the threaded groove 5564 runs through the center point of the limiting plate 2 5563, the solid column 5562, and the limiting plate 1 5561, and the small bolt 5565 is connected to the limiting plate 1 5561 through the threaded groove 5564. The limiting plate 2 5563, the solid column 5562 and the limiting plate a11 are threadedly connected, the edge of the solid column 5562 coincides with the inner layer of the rotating ring 557 and the upper and lower layers of the rotating ring 557 are restrained by the limiting plate 1 5561 and the limiting plate 2 5563; the limiting plate 1 5561 and the limiting plate 2 5563 are installed on the solid column 5562 in a completely symmetrical orientation and are finely polished with the surface, and the threaded groove 5564 penetrates the center points of the limiting plate 1 5561, the limiting plate 2 5563 and the solid column 5562 in a completely penetrating form.

[0031] The limit plate 1 5561 and the limit plate 2 5563 can restrain the upper and lower layers of the component through symmetrical arrangement on the solid column 5562, to prevent falling off and center point deviation during rotation, and then prevent the component from getting stuck during rotation through fine polishing. The thread groove 5564 can penetrate and lock the small bolt 5565 through completely vertical penetration, thereby locking the position of the entire component.

[0032] The power rod 1 of the micro probe used for three-dimensional measurement of precision machinery can be embedded in the corresponding manufacturing machine in combination with the locking sleeve 2, and then locked and positioned by the locking sleeve 2. Subsequently, the airtight ring 3 can fill the gap between the measuring probe 4 and the locking sleeve 2, avoiding the adverse effects caused by the cutting fluid splashing into the gap. Then, when the measuring probe 4 generates and measures the components in a cycle, the dehumidifier 5 can operate according to the corresponding procedure to blow off the cutting fluid on the measuring probe 4 and dry it, thereby ensuring the cleanliness of the measuring probe 4 and avoiding contamination that reduces the subsequent detection accuracy.

[0033] The connecting plate 51 of the dehumidifier 5 will be fixed to the upper end of the airtight ring 3, and the electric shaft sleeve 52 it carries can cover the internal electric shaft through the sealing cover 53 to avoid contact with the outside world, thereby ensuring the dryness of the electric shaft. Subsequently, the through groove 54 of the electric shaft sleeve 52 covers the edge of the measuring probe 4, and after the measuring probe 4 is covered and soaked with cutting fluid, the dehumidification end 55 on the inner wall of the electric shaft sleeve 52 can operate according to the guidance of the program, and the dehumidification end 55 will activate the internal high-speed fan to blow off the cutting fluid on the surface of the measuring probe 4, and then use the air-drying effect to complete the generation and detection of high-precision images maintaining the measuring probe 4.

[0034] The dehumidification end 55 can improve the origin positioning of the main body on the inner wall of the electric shaft sleeve 52 through the newly added rigid ring 551 on the surface, and then the six slots 552 opened in the inner layer of the rigid ring 551 can be adapted to the number of fixing parts, so that the fixing parts can be installed on the edge of the limiting ring 554. The limiting ring 554 can complete the splicing with the rigid ring 551 through the fixing parts and the slots 552, and then maintain the same center point. Then the waterproof net 555 inside the limiting ring 554 can prevent a large number of water molecules from directly impacting and entering the dehumidification end 55 according to its own grid shape, and then the waterproof net 555 does not affect the high-speed wind energy spraying process of the dehumidification end 55, so that the waterproof net 555 can prevent water from entering the dehumidification end 55, thereby retaining the original quick air drying effect of offsetting water molecules.

[0035] The positioning wheel 556 of the fixing part will be fixed to the edge of the limiting ring 554, so that the rotating ring 557 can rotate on the edge of the positioning wheel 556 under the restraint of the positioning wheel 556, and then drive the overlapping gasket a4, the magnetic block 559 and the semicircular buckle 560 to rotate in position through the vertical column 553. After the semicircular buckle 560 is embedded in the slot 552, the overlapping gasket 558 can be combined with the magnetic block 559 to increase the clamping tightness between the buckle 560 and the slot 552, so as to improve the connection firmness between the components and avoid falling off caused by the operation of the high-speed fan of the dehumidification end 55. Subsequently, due to the effect that the clamping and magnetic attraction are both manually detachable and the shape of the semicircular buckle 560 can facilitate the subsequent manual removal of the waterproof net 555 from the rigid ring 551, thereby improving the convenience of subsequent maintenance of each component.

[0036] The edge of the solid column 5562 of the positioning wheel 556 can contact the inner layer of the rotating ring 557, and then the limit plate 2 5563 and the limit plate 1 5561 at the upper and lower ends of the solid column 5562 can restrain and limit the upper and lower layers of the rotating ring 557 according to the large-diameter fine polishing shape to avoid the center of the circle from being separated during rotation. Subsequently, the small bolt 5565 can be locked in with the vertically completely penetrating thread groove 5564 to ensure the origin fixation of the solid column 5562, and then the fixation and subsequent rapid disassembly can be enhanced by relying on the thread restraint.

[0037] The measuring probe 4 is provided with a data power supply rod 41, an identification calculation chip 42, a waterproof column 43, a telescopic groove 44, a movable body 45, a wiping cover 46, and a probe body 47. The data power supply rod 41 is fixed to the lower end of the waterproof column 43 and is electrically connected to the identification calculation chip 42 at the edge of the waterproof column 43. The top edge of the waterproof column 43 is provided with a telescopic groove 44. The movable body 45 matches the telescopic groove 44 so as to be embedded in the inner layer area of ​​the waterproof column 43 and is electrically connected to the data power supply rod 41. The wiping cover 46 is installed on the inner layer of the movable body 45. The probe body 47 is fixed to the top of the waterproof column 43. The center of the probe body 47 is electrically connected to the identification and computing chip 42 and the data power-on rod 41. The edge of the probe body 47 contacts the inner layer of the wiping sleeve 46 through the movable body 45 of the telescopic slot 44. The identification and computing chip 42 is exposed in the through slot 54 area through the waterproof column 43 and communicates with the dehumidification end 55. The data power-on rod 41 is vertical. Two groups of identification and computing chips 42 are arranged on the waterproof column 43. The inner wall of the telescopic slot 44 is finely polished and contains a spherical pulley that contacts the surface of the movable body 45. The surface of the movable body 45 contains a movable slider. The wiping sleeve 46 is a rubber product.

[0038] The data power rod 41 can be connected to the component in an interlaced manner through a vertical form. The identification calculation chip 42 can improve the measurement accuracy of the component through repeated calculations in two groups on the waterproof column 43. The telescopic groove 44 can ensure that the movable body 45 can move up and down in a stable state through the fine polishing of the inner wall and the spherical pulley carried. The movable body 45 can slide in the telescopic groove 44 with the cooperation of the moving slider. The wiping sleeve 46 can quickly scrape off the water molecules and impurities on the surface of the component according to the rubber product. The telescopic groove 44 is a whole The body is in the form of a cylinder, and its internal groove is set in a vertical orientation, so that the shape of the movable body 45 is consistent with the shape of the telescopic groove 44, and it can enter the telescopic groove 44 by vertically falling. The shape of the wiping sleeve 46 is consistent with the shape of the inner wall of the movable body 45. The wiping sleeve 46 can cover the inner wall area of ​​the movable body 45, and then when the movable body 45 moves up and down in the telescopic groove 44 area, the wiping sleeve 46 will contact and wipe the probe body 47. The ball pulley is installed on the inner wall area of ​​the telescopic groove 44, and the slider is installed on the outer area of ​​the movable body 45. The surface of the slider is open. There is a vertical rail that can be controlled by the ball pulley, so that when the ball pulley is forward and reversed, it can drive the sliding body 45 to move up and down in the telescopic groove 44 area through the slider. The two can drive the internal wiping sleeve 46 to move up and down while cooperating with each other, so that impurities and residual cutting fluid on the surface of the probe body 47 can be removed, thereby improving the surface cleanliness of the probe body 47. Combined with the external slider of the movable body 45 and the ball pulley inside the telescopic groove 44, the two can move up and down in coordination with each other, and the wiping sleeve 46 can change its position following the position of the movable body 45, and then according to the The wiping sleeve 46 is located at the edge of the probe body 47, so that the movable body 45 can wipe the probe body 47 when operating in conjunction with the spherical pulley inside the telescopic groove 44. The waterproof column 43 is installed in the through groove 54 area of ​​the electric shaft sleeve 52, and it will be perpendicular to the center area of ​​the through groove 54. Therefore, the dehumidification end 55 on the edge of the inner wall of the electric shaft sleeve 52 will form a communication shape with the identification and computing chip 42 on the edge of the waterproof column 43. Through the communication effect, the water molecules on the identification and computing chip 42 can be removed while the dehumidification end 55 is operating, thereby ensuring the dryness of the identification and computing chip 42.

[0039] Among them, the identification calculation chip 42 is provided with an insulator 421, a power connection block 422, a chip body 423, an anti-fouling plate 424, a computing module 425, and a data transmission shaft 426. The insulator 421 covers the outer layer of the power connection block 422, the computing module 425, and the data transmission shaft 426. The chip body 423 is perpendicular to the power connection block 422 through the insulator 421. The anti-fouling plate 424 covers the outer layer of the chip body 423. The computing module 425 is positioned on both sides of the back of the chip body 423. One end of the data transmission shaft 426 is connected to the center of the computing module 425 and the other end passes through the insulator 421 to be electrically connected to the power connection block 422. The power connection block 422 carries the data transmission shaft 426 through the insulator 421 and is embedded in the waterproof column 43, and is connected to the probe body 4 7. The data power rod 41 is electrically connected; the insulator 421 has three forms, which are adapted to the power connection block 422, the computing module 425, and the data transmission shaft 426. The chip body 423 has an anti-fouling plate 424 of the same shape on the outside. The computing module 425 and the data transmission shaft 426 have two groups respectively installed in the upper middle and lower middle positions of the chip body 423; the circuit in the data transmission shaft 426 can be connected to the inside of the waterproof column 43, so that the ball pulley carried by the telescopic groove 44 inside the waterproof column 43 can be powered on, and the data transmission shaft 426 can be inserted through a hole opened on the edge of the waterproof column 43. The chip body 423, the anti-fouling plate 424, and the computing module 425 are assembled in a way that they are overlapped, interspersed, and fixed one by one to form a whole.

[0040] The insulator 421 can avoid power leakage when the power connection block 422, the computing module 425, and the data transmission shaft 426 are in use through three forms. The anti-fouling plate 424 outside the chip body 423 can prevent the contamination caused by the direct contact of the cutting fluid with the chip body 423. The computing module 425 and the data transmission shaft 426 can improve the transmission stability of the detection data through two groups.

[0041] The data power rod 41 of the measuring probe 4 will be inserted into the locking sleeve 2 and spliced ​​with the power rod 1, and then the waterproof column 43 on the data power rod 41 can use two sets of identification and calculation chips 42 to repeatedly calculate the size of the component screen to achieve the effect of accurate measurement, and then the telescopic groove 44 of the waterproof column 43 can combine the slider of the movable body 45 with the internal spherical ball to allow the movable body 45 to move up and down in the waterproof column 43 in a smooth manner, and then the movable body 45 will drive the rubber wiping sleeve 46 to scrape off the cutting fluid and impurities on the edge of the probe body 47. Combined with the effect of the dehumidification end 55, the cleanliness of the probe body 47 can be improved to prevent the secondary impact of impurities on the edge on the detection accuracy.

[0042] Identify the three forms of the computing chip 42. The insulator 421 can wrap the outer layer of the power connection block 422, the computing module 425, and the data transmission shaft 426. Then the data transmission shaft 426 of the computing module 425 can penetrate the insulator 421 to complete the connection with the power connection block 422, so as to achieve a stable electrical connection to prevent power leakage. Then the power connection block 422, the computing module 425, and the data transmission shaft 426 can be embedded in the waterproof column 43 to complete the electrical connection with the lower end data power rod 41, and achieve a stable data transmission effect. Then the anti-fouling plate 424 on the surface of the chip body 423 can completely isolate impurities and cutting fluid from the outside, preventing the cutting fluid and impurities from directly contacting the chip body 423 to cause irreversible damage to the chip body 423, thereby increasing the service life of the chip body 423.
