The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0022] Example 1 See also Figure 1-4The present invention provides a technical solution: a CNC machine tool for spherical polishing, comprising a machine body 1, two trapezoidal boxes fixedly connected to the top of the machine body 1, a movable door rotatably connected to the front of the machine body 1, and tempered glass fixedly connected to the surface of the movable door, a temperature sensor embedded in the machine body 1, a controller 2 fixedly connected to the front of the machine body 1 to assist in cooling the interior of the machine body 1 and reduce the flying of grinding debris, a liquid tank 3 fixedly connected to the bottom of the inner wall of the machine body 1, a metal mesh plate fixedly connected to the top of the liquid tank 3, and a coolant loaded inside the liquid tank 3; In order to fix the spherical structure workpiece and drive the spherical structure workpiece to rotate and grind, the left side of the inner wall of the body 1 is rotatably connected with a fixed heat-conducting mechanism 4. There are two fixed heat-conducting mechanisms 4 and they are symmetrically distributed on the left and right sides of the body 1. The fixed heat-conducting mechanism 4 is located on the top of the liquid tank 3. The fixed heat-conducting mechanism 4 includes a fixed suction cup 41. In order to reduce the extrusion and wear of the spherical structure workpiece, the fixed suction cup 41 includes a disk body 411. The disk body 411 is made of silicone. A hard air guide tube 412 is fixedly connected to the left side of the disk body 411 to achieve ventilation and transmission at the same time. The outer surface of the hard air guide tube 412 is rotatably connected to the left side of the body 1. In order to achieve contact and heat dissipation with the spherical structure workpiece and further enhance the fixing effect of the spherical structure workpiece, a telescopic contact sleeve 42 is fixedly connected to the outer surface of the hard air guide tube 412. The telescopic contact sleeve The sleeve 42 includes a fixed sleeve rod 421, the interior of the fixed sleeve rod 421 is fixedly connected to the outer surface of the hard air guide tube 412, the inner side of the fixed sleeve rod 421 is a hollow structure, the left side of the fixed sleeve rod 421 is slidably connected to the sliding sleeve rod 422, the fixed sleeve rod 421 and the sliding sleeve rod 422 are fixedly connected by a spring, the sliding sleeve rod 422 is made of copper, and a rubber ring is fixedly connected to the right side of the sliding sleeve rod 422. In order not to affect the air extraction and fixing process, the left side of the hard air guide tube 412 is fixedly connected to the adapter 43, and the adapter 43 includes an air pipe fixing head 431, and the right side of the air pipe fixing head 431 is fixedly connected to the outer surface of the hard air guide tube 412, and the left side of the air pipe fixing head 431 is rotatably connected to a rotating connector 432, and the rotating connector 432 is communicated with an external air pump for achieving adsorption and fixation of the spherical structure workpiece by air extraction; The left side of the machine body 1 is rotatably connected to a linkage ventilation mechanism 5 , the bottom of the inner wall of the machine body 1 is fixedly connected to a fixed heat exchange mechanism 6 , and the back of the inner wall of the machine body 1 is fixedly connected to a linkage polishing mechanism 7 .

[0023] When in use, the movable door is opened, and the spherical structure workpiece to be polished is placed between the two sliding sleeve rods 422. The sliding sleeve rod 422 and the fixed sleeve rod 421 will slide relative to each other, thereby squeezing the spring. The spring will apply pressure to the surface of the spherical structure workpiece through the sliding sleeve rod 422, while ensuring that the disc body 411 can be completely fitted with the spherical structure workpiece. After it is placed securely, the external air pump is started. After the air pump is started, the gas inside the disc body 411 is extracted through the hard air guide tube 412. At this time, negative pressure is formed inside the disc body 411, thereby adsorbing the spherical structure workpiece, completing the fixing process of the spherical structure workpiece. After the fixing is completed, the movable door is closed, and then the entire device is started through the controller 2; After the device is started, the spherical structure workpiece rotates driven by the disk 411 and the sliding sleeve rod 422. The disk 411 rotates driven by the linkage ventilation mechanism 5 through the hard air guide tube 412, and the surface of the spherical structure workpiece is polished with the cooperation of the linkage polishing mechanism 7. During the polishing process, the heat generated by friction is transferred from the surface of the spherical structure workpiece to the sliding sleeve rod 422, and then transferred from the sliding sleeve rod 422 to the fixed sleeve rod 421, and then transferred from the fixed sleeve rod 421 to the fixed heat exchange mechanism 6.

[0024] Example 2 See also Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: in order to achieve cooling inside the device, a linked ventilation mechanism 5 is provided to discharge hot air while inhaling cold air. The linked ventilation mechanism 5 includes: The intermediate linkage disk 51 is rotatably connected to the left side of the body 1, and the inner side of the outer surface of the intermediate linkage disk 51 is fixedly connected to the outer surface of the hard air guide tube 412 in the radial direction of the hard air guide tube 412. The inner side of the outer surface of the intermediate linkage disk 51 is slidingly connected to the outer surface of the hard air guide tube 412 in the axial direction of the hard air guide tube 412. The outer surface of the intermediate linkage disk 51 is fixedly connected with a gear ring, and a gear is fixedly connected to the left side of the intermediate linkage disk 51. The left side of the body 1 is fixedly connected with a motor, and the motor is electrically connected to the controller 2 through a wire. The motor on the left side of the body 1 is a DC motor, and a gear is fixedly connected to the right side of the motor on the left side of the body 1. The gear of the motor on the left side of the body 1 is meshed with the gear on the left side of the intermediate linkage disk 51. The number of teeth of the gear of the motor on the left side of the body 1 is greater than the number of teeth of the gear on the left side of the intermediate linkage disk 51, so as to realize the rapid rotation of the spherical structure workpiece, thereby helping to improve the grinding effect; The linked ventilation blade disc 52 is rotatably connected to the left side of the body 1. Blades are fixedly connected inside the linked ventilation blade disc 52, which increases the flow rate of gas blown to the surface of the workpiece and promotes cooling and debris removal during workpiece grinding. The linked ventilation blade disc 52 is rotatably connected to the trapezoidal box on the top of the body 1. A gear ring is fixedly connected to the outer surface of the left side of the linked ventilation blade disc 52. The number of teeth of the gear ring on the outer surface of the left side of the linked ventilation blade disc 52 is less than the number of teeth of the gear ring on the outer surface of the intermediate linkage disc 51. The intermediate linkage disc 51 is meshed with the gear ring of the linked ventilation blade disc 52 through the gear ring. The number of the intermediate linkage disc 51, the linked ventilation blade disc 52 and the motor on the left side of the body 1 are all two, and are symmetrically distributed on the left and right sides of the body 1. Among them, the blades of the two linked ventilation blade discs 52 have the same inclination direction to achieve a continuous intake and exhaust process.

[0025] During use, after the device is started, the controller 2 controls the DC motor engaged with the intermediate linkage disk 51 to start. After the DC motor starts, it drives the intermediate linkage disk 51 to rotate. The rotation of the intermediate linkage disk 51 drives the linkage ventilation blade disk 52 to rotate. At the same time, the rotation of the intermediate linkage disk 51 drives the hard air guide tube 412 to rotate, and then drives the disk body 411, the telescopic contact sleeve 42 and the spherical structure workpiece to rotate through the hard air guide tube 412, thereby realizing the rotation process of the spherical structure workpiece; At the same time, the rotation of the linked ventilation blade disk 52 drives the blades inside it to rotate. The rotation of the blades on the left side sucks the external cold air into the body 1. After the cold air enters the body 1, it is guided by the trapezoidal box and blows onto the surface of the spherical workpiece, taking away the heat generated during the grinding process and blowing away the debris on the surface of the spherical workpiece to prevent the debris from affecting the quality of the workpiece surface during grinding. After absorbing the heat, the cold air expands and flows upward. At this time, the linked ventilation blade disk 52 on the right side drives the blades to rotate and suck the hot air inside the device out of the body 1, and discharges the hot air from the body 1. This cycle is repeated, thereby maintaining the temperature inside the body 1. During this process, the temperature sensor embedded in the body 1 monitors the temperature data changes inside the body 1 in real time, and transmits the data back to the controller 2. The controller 2 adjusts the speed of the DC motor engaged with the intermediate linkage disk 51 according to the data transmitted back by the body 1, thereby realizing the regulation of the intake and exhaust flow rate, and at the same time realizing the regulation of the rotation speed of the spherical structure workpiece.

The interior of the rectangular plate of the fin body 621 is slidably connected to a movable leaf 622. The enclosed space formed by the rectangular plate and the movable leaf 622 is filled with hydraulic oil. This enables the heat sink to increase its heat dissipation area as the coolant temperature rises, thereby helping to improve the heat dissipation effect, thereby helping to improve the polishing effect of the device. In order to grind the spherical structure workpiece, a linkage grinding mechanism 7 is provided. The linkage grinding mechanism 7 is located on the top of the liquid tank 3 and the linkage grinding mechanism 7 is located on the back of the fixed heat conducting mechanism 4. The linkage grinding mechanism 7 includes a driving slide box 71. The driving slide box 71 includes a box body 711. The back of the box body 711 is fixedly connected to the back of the inner wall of the body 1. An electromagnetic slide rod is buried on the top of the inner wall of the box body 711. The electromagnetic slide rod is electrically connected to the controller 2 through a wire. A laser ranging sensor is fixedly connected to the top of the box body 711 for detecting The distance from the movable grinding plate 72 to the surface of the spherical structure workpiece, the laser distance measuring sensor is electrically connected to the controller 2 through a wire, the bottom of the box 711 is fixedly connected to the lower baffle 712, which is used to realize collision vibration with the slide body 731, thereby self-cleaning the elastic scraper 732, and the movable grinding plate 72 is slidably connected to the inside of the box 711. The front surface of the movable grinding plate 72 is a circular arc concave surface, and the back of the movable grinding plate 72 is fixedly connected to the front of the box 711 through a spring.

The elastic scraper 732 is made of silicone. A linkage drive wheel 74 is rotatably connected to the inside of the rectangular blind hole of the box 711. The linkage drive wheel 74 includes a hydraulic blade 741. Three blades are fixedly connected to the surface of the hydraulic blade 741. The blades are evenly distributed on the surface of the hydraulic blade 741. The hydraulic blade 741 is rotatably connected to the inside of the rectangular blind hole of the box 711. A trigger cam 742 is fixedly connected to the bottom of the hydraulic blade 741. The trigger cam 742 is located at the bottom of the outer wall of the box 711.

[0027] During use, after the device is started, the controller 2 controls the circulation pump of the three-dimensional liquid guide tube 61 to start. After the circulation pump is started, the circulation of the coolant inside the fixed heat exchange mechanism 6 and the linkage grinding mechanism 7 is promoted. During the rotation of the spherical structure workpiece in Example 1 and Example 2, the heat transferred from the grinding process of the spherical structure workpiece absorbed by the sliding sleeve 422 is transferred to the hollow rectangular rod of the three-dimensional liquid guide tube 61 through the copper ring of the three-dimensional liquid guide tube 61. The coolant inside the hollow rectangular rod absorbs the heat and brings the heat from the three-dimensional liquid guide tube 61 to the inside of the row body 621 under the circulation of the coolant. The heat is transferred from the row body 621 to the movable page 622. During this process, the hydraulic oil inside the rectangular plate expands due to the heat, and the hydraulic oil pushes the movable page 622 to slide backward, thereby increasing the area of the surface of the movable fin heat sink 62 in contact with the external cold air, and ultimately promoting heat dissipation. As the heat transferred by the movable fin heat sink 62 increases, the displacement of the movable page 622 increases until the movable page 622 reaches the limit position. During this process, the controller 2 controls the electromagnetic slide bar of the box 711 to start, and the electromagnetic slide bar pushes the movable grinding plate 72 to slide forward. After the movable grinding plate 72 slides forward, it contacts and rubs with the surface of the spherical structure workpiece, thereby realizing the grinding of the surface of the spherical structure workpiece. During this process, the laser ranging sensor of the box 711 monitors the distance data changes from the movable grinding plate 72 to the surface of the spherical structure workpiece in real time, and transmits the distance data back to the controller 2 in real time, thereby realizing the detection of the grinding effect of the surface of the spherical structure workpiece, and adjusts the position of the electromagnetic slide bar in real time according to the change trend of the monitoring data, and then adjusts the distance and contact pressure between the movable grinding plate 72 and the surface of the spherical structure workpiece, thereby improving the grinding accuracy and grinding quality; During the process of the aforementioned movable grinding plate 72 grinding the surface of the spherical structure workpiece, the coolant flows through the rectangular blind hole of the box body 711, and the movable grinding plate 72 transfers the heat generated during the grinding process to the inside of the box body 711 through the slide rod of the electromagnetic slide rod, and finally transfers it to the coolant. At the same time, the flow of the coolant drives the liquid-driven blade 741 to rotate, and the rotation of the liquid-driven blade 741 drives the trigger cam 742 to rotate. The rotation of the trigger cam 742 periodically contacts the rectangular rod of the slide body 731, pushing the slide body 731 to slide forward periodically, and the slide body 731 cycles The periodic forward sliding drives the elastic scraper 732 to slide together. After sliding, the elastic scraper 732 periodically contacts the surface of the spherical structure workpiece, thereby periodically scraping the surface of the spherical structure workpiece, thereby achieving the cleaning of the surface of the spherical structure workpiece. After the elastic scraper 732 completes the contact with the surface of the spherical structure workpiece, it resets under the action of the spring. After the reset, the slide body 731 contacts and collides with the lower stopper 712. The collision generates vibration, and the debris scraped and adhered by the elastic scraper 732 is removed by vibration, thereby achieving the self-cleaning of the elastic scraper 732. In the above process, the debris blown away by the airflow and the debris scraped off will fall into the coolant inside the liquid tank 3, preventing the debris from flying up again and contaminating the workpiece surface.
