Its main function is to support the spindle and make it rotate, and realize the functions of spindle starting, braking, speed change and reversing. During the working process, the spindle box will generate a lot of heat due to the high-speed rotation of the spindle and the generation of cutting force.

[0042] Example

[0043] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] The present invention provides a high heat dissipation spindle box for special processing machine tools and a method for using the same. The spindle box comprises a spindle box 1 and a cooling box 2. The spindle box 1 is provided with a pump body 11. The pump body 11 is connected to the spindle box 1 and the cooling box 2 respectively through a first pipeline 111 and a second pipeline 112. The pump body 11 extracts lubricating oil in the spindle box 1 through the first pipeline 111 and transmits the lubricating oil to the inside of the cooling box 2 through the second pipeline 112. A nozzle corresponding to the cooling box 2 is provided on the top of the second pipeline 112 to atomize the lubricating oil.

[0045] In this embodiment, a cooling and cooling support assembly 21 and an adjustment assembly 22 corresponding to the cooling and cooling support assembly 21 are provided in the cooling box 2. The cooling and cooling support assembly 21 includes a first cooling plate 211, a second cooling plate 212, and a bottom plate 213. The first cooling plate 211 is hinged with the second cooling plate 212, and the second cooling plate 212 is supported by the adjustment assembly 22. The bottom of the cooling box 2 is connected to the spindle box 1.

[0046] In this embodiment, the adjustment component 22 includes a roller screw 221 and a support rod 222. The roller screw 221 is provided with a threaded sleeve 223. The sleeve 223 is connected to the second cooling plate 212 through the support rod 222. The two ends of the support rod 222 are respectively hinged to the second cooling plate 212 and the sleeve 223. A baffle 224 is provided on the top of the roller screw 221. The baffle 224 is located at the top of the cooling and cooling support component 21 to shield the first cooling plate 211. The bottom plate 213 is located at the bottom of the second cooling plate 212 and forms an open cavity between the first cooling plate 211 and the second cooling plate 212. There is a gap between the bottom plate 213 and the second cooling plate 212. An exhaust port corresponding to the gap is provided on the cooling box 2. A synchronous belt transmission mechanism is provided on the top of the roller screw 221. The motor drives the roller screw 221 to rotate through the synchronous belt transmission mechanism.

[0047] In this embodiment, a cold air component 3 is provided at the bottom of the spindle box 1. The cold air component 3 penetrates into the cavity through a third pipe 31 to transport cold air into the cavity.

[0048] When the present embodiment is in use, the pump body 11 extracts the lubricating oil in the spindle box 1 through the first pipe 111 and then transmits the lubricating oil to the top of the cooling box 2 through the second pipe 112, and atomizes the lubricating oil through the nozzle. The atomized lubricating oil is shielded by the baffle 224 to prevent the lubricating oil from being sprayed on the first cooling plate 211. At the same time, the cold air component 3 starts to work and transports cold air into the cavity through the third pipe 31 to cool the second cooling plate 212. The atomized lubricating oil is sprayed on the second cooling plate 212 to cool the lubricating oil. The cooled lubricating oil drips along the second cooling plate 212 to the bottom of the cooling box 2 and finally flows into the spindle box 1, thereby cooling the spindle box 1. During the dripping process of the lubricating oil, the cold air in the cavity is discharged outward through the gap to cool the lubricating oil again, and during the cooling process, the roller screw 22 is driven by the motor 1 rotates, the roller screw 221 and the sleeve 223 are threadedly connected to drive the sleeve 223 to move up and down along the roller screw 221, and the sleeve 223 drives the support rod 222 to rotate during the movement, and the support rod 222 supports the second cooling plate 212. When the sleeve 223 moves upward, the second cooling plate 212 is driven by the support rod 222 to flip upward around the hinge point with the first cooling plate 211. 2 The second cooling plate 212 tends to be horizontal, and the dripping speed of the lubricating oil can be slowed down in the process of cooling the lubricating oil, the residence time of the lubricating oil on the second cooling plate 212 is prolonged, and the temperature of the lubricating oil is greatly reduced. When the sleeve 223 moves downward, the second cooling plate 212 is driven to flip downward through the support rod 222, the inclination angle of the surface of the second cooling plate 212 is increased, and the dripping speed of the lubricating oil is accelerated, which can show the rapid cooling of the lubricating oil.

[0049] Compared with the prior art, the lubricating oil in the spindle box 1 is extracted and atomized by the pump body 11 and then sprayed on the second cooling plate 212 in the cooling box 2. At the same time, the cold air component 3 is used to transport cold air into the cavity and then discharge it from the gap, thereby achieving double cooling of the lubricating oil, which helps to maintain the temperature in the spindle box 1 stable, thereby extending the service life of the machine tool. The roller screw 221 is driven by the motor to rotate, and then the flipping angle of the second cooling plate 212 is controlled, so that the residence time and dripping speed of the lubricating oil on the second cooling plate 212 can be intelligently adjusted according to actual needs, which not only ensures the sufficient cooling of the lubricating oil, but also improves the flexibility of the cooling process. Example

[0050] In the above embodiment, the lubricating oil is sprayed onto the second cooling plate 212 through a nozzle for cooling. However, during use, the parts in the machine tool spindle box will produce iron filings due to wear during operation. These iron filings may enter the lubricating oil system as the lubricating oil circulates. However, the iron filings will destroy the lubricating oil film and reduce the lubrication performance, thereby aggravating the wear of the internal parts of the machine tool spindle box and interacting with the moisture, oxygen, etc. in the lubricating oil to accelerate the corrosion of the internal parts of the machine tool spindle box. Therefore, the embodiment of the present application optimizes the cooling box 2 to a certain extent based on the above embodiment.

[0051] In this embodiment, a plurality of electromagnets 2121 are provided on the second cooling plate 212. The plurality of electromagnets 2121 are arranged on the second cooling plate 212 in a circumferentially staggered spiral distribution. A coil with adjustable current intensity is arranged inside the electromagnet (2121). The magnetic force thereof is between 0.1 and 0.5 Tesla. The edges on both sides of the electromagnet (2121) are wavy curves. The wavy curves are one-tenth of the length of the electromagnet (2121). The height of the wavy curves is one-fifth of the electromagnet (2121). The electromagnet (2121) is designed to be inclined. The inclination angle of the electromagnet (2121) is 5°. The center point of each electromagnet is located at the crest or trough of the edge curve of the previous electromagnet. The electromagnet (2121) is provided with a notch at the curved portion. The notch is located at one end of the electromagnet (2121) close to an adjacent electromagnet (2121). The width of the notch is one-third of the thickness of the electromagnet (2121). The cooling box 2 is provided with 2 controllers corresponding to the electromagnet 2121, which realize continuous adjustment of the magnetic force between 0.1 and 0.5 Tesla. The electromagnet 2121 blocks the injected lubricating oil. After being energized, the electromagnet 2121 absorbs the iron filings in the lubricating oil. The electromagnet 2121 is inclined on the second cooling plate 212, and the two sides of the electromagnet 2121 are curved to increase the contact area with the lubricating oil. A discharge port 23 and a filter screen 24 corresponding to the discharge port 23 are provided at the bottom of the cooling box 2. A control valve is provided on the discharge port 23, and the filter screen 24 is located at the bottom of the cooling box 2 and is inclined.

[0052] When the nozzle of this embodiment is in use, the controller starts the electromagnet 2121 during the spraying process. The lubricating oil with iron filings contacts the electromagnet 2121 during the process of sliding down along the second cooling plate 212. The iron filings are adsorbed on the electromagnet 2121 and separated from the lubricating oil. The electromagnet 2121 has a smooth transition of wavy curves on both sides without sharp edges or mutation points, so as to reduce the flow resistance of the lubricating oil and effectively make the lubricating oil slide along the surface of the electromagnet 2121. The contact area can be effectively increased through the curve design to ensure the adsorption of iron filings in a large range. The filter screen 24 at the bottom of the cooling box 2 performs secondary filtration on the lubricating oil to ensure that the lubricating oil entering the spindle box 1 does not contain iron filings. After use, the magnetism of the electromagnet 2121 is controlled by the controller, and the iron filings on the electromagnet 2121 slide along the second cooling plate 212 to the bottom of the cooling box 2 and are discharged from the inside of the cooling box 2 through the discharge port 23.

[0053] In this embodiment, the strength of the magnetic force is controlled by adjusting the current during use, and the electromagnet 2121 adopts a flat rectangular or elliptical basic shape to better fit the surface of the second cooling plate 212. Compared with the prior art, by arranging multiple electromagnets 2121 on the second cooling plate 212, and these electromagnets 2121 are staggered in a circumferential spiral, the contact area with the lubricating oil can be increased, and the center point of each electromagnet 2121 is located at the crest or trough of the edge curve of the previous electromagnet 2121, ensuring that the space between the electromagnets 2121 is maximized and mutual interference is avoided. The magnetic fields generated by adjacent electromagnets in the energized state should be partially superimposed to form a stronger magnetic field area to improve the adsorption efficiency of iron chips, thereby more effectively adsorbing iron chips in the lubricating oil. It ensures that the iron filings have sufficient contact time with the electromagnet 2121 during the sliding process, thereby improving the removal efficiency of the iron filings. The inclined design and wavy curve of the electromagnet 2121 help the lubricating oil to flow smoothly along its surface, reducing the retention of lubricating oil on the electromagnet 2121 and avoiding the accumulation of oil, thereby ensuring the smooth flow and uniform distribution of lubricating oil and reducing accumulation. The inclined and wavy curve design of the electromagnet 2121 also makes it easier for the iron filings to be adsorbed by the electromagnet 2121 during the sliding process, which helps the electromagnet 2121 to capture the lubricating oil more comprehensively. Iron chips in the oil improve the accuracy and efficiency of adsorption, and timely remove iron chips in the lubricating oil to reduce the wear and blockage of the inside of the spindle box 1 by iron chips, thereby extending the service life of the spindle box and improving stability, and helping to maintain the cleanliness of the lubricating oil to ensure the normal operation of the system. The filter 24 at the bottom of the cooling box 2 performs secondary filtration on the lubricating oil to further ensure that the lubricating oil entering the spindle box 1 does not contain iron chips and is discharged through the discharge port 23, simplifying the cleaning process. The double filtration mechanism improves the purity of the lubricating oil and provides a strong guarantee for the stable operation of the equipment;

[0054] A notch is provided at the curved position of the electromagnet 2121 (such as the crest or trough of the wave-shaped curve), and the width of the notch is about one third of the thickness of the electromagnet. The notch should correspond to one end of the adjacent electromagnet so that the iron filings can smoothly enter the adsorption area of ​​the adjacent electromagnet during the sliding process to achieve continuous adsorption. Example

[0055] In the above embodiment, although the magnetism of the electromagnet 2121 can be controlled by the controller after the electromagnet 2121 adsorbs the iron filings in the lubricating oil, the iron filings on the electromagnet 2121 cannot all fall off, and residues are likely to affect the subsequent adsorption effect of the iron filings in the lubricating oil. Therefore, the embodiment of the present application optimizes the adjustment component 22 based on the above embodiment.

[0056] In this embodiment, the adjustment component 22 also includes a support roller 225, a first cleaning roller 226, and a second cleaning roller 228. The support roller 225 runs through the roller screw 221 and is rotatably connected to the roller screw 221 through a transmission component 227. The baffle 224 is located at the top of the support roller 225 and is fixedly connected to the support roller 225. The first cleaning roller 226 is located between the second cooling plate 212 and the baffle 224 and is hinged to the support roller 225. The second cleaning roller 228 is located at the bottom of the support roller 225 and its bottom is connected to the bottom inner wall of the cooling box 2.

[0057] The transmission assembly 227 includes a sliding block 2271 and an insert block 2272. The sliding block 2271 is located at the bottom of the roller screw 221 and is slidably connected to the roller screw 221. The bottom of the roller screw 221 is provided with a first slide groove corresponding to the sliding block 2271. The insert block 2272 is located below the sliding block 2271 and is fixedly connected to the support roller 225. The insert block 2272 is provided with a plurality of second slide grooves distributed longitudinally around the circumference. The inner wall of the sliding block 2271 is provided with a convex block corresponding to the second slide groove. The outer wall of the insert block 2272 is slidably connected to the inner wall of the sliding block 2271.

[0058] The outer wall of the sliding block 2271 is provided with a spring 2273, the top of the spring 2273 is fixedly connected to the sliding block 2271 and the bottom is provided with a stopper 2275, and the bottom of the insert block 2272 is provided with a retaining ring 2274 corresponding to the stopper 2275;

[0059] The top of the sliding block 2271 is an annular opening, wherein the diameter of the opening corresponds to the bottom of the shaft sleeve 223 .

[0060] In the process of using this embodiment, when it is necessary to clean the iron filings on the electromagnet 2121, the roller screw 221 drives the sleeve 223 to move downward so that the second cooling plate 212 is tilted downward to facilitate the iron filings to slide onto the bottom of the cooling box 2. When the sleeve 223 moves to the top of the transmission assembly 227 and contacts the sliding block 2271, the roller screw 221 continues to rotate to squeeze the sliding block 2271 downward, and the sliding block 2271 slides downward along the first slide groove. In the process of sliding downward, the sliding block 2271 rotates in a circle through the roller screw 221, and the protrusion on the sliding block 2271 is inserted into the plug block 227. 2, the second slide groove drives the support roller 225 and the roller screw 221 to rotate synchronously through the plug block 2272, and the support roller 225 drives the upper first cleaning roller 226 and the lower 228 to rotate synchronously, the first cleaning roller 226 cleans the iron filings on the electromagnet 2121, and the iron filings fall to the bottom of the cooling box 2 along the second cooling plate 212, and the second cleaning roller 228 rotates to gather the iron filings at the bottom of the cooling box 2 at the middle position and discharge them from the cooling box 2 through the discharge port 23. The second cleaning roller 228 effectively prevents the iron filings from remaining at the bottom of the cooling box 2 during the rotation and cleaning process, and effectively prevents the lubricating oil from mixing with the iron filings for the second time.

[0061] Compared with the prior art, the electromagnet is cleaned directly by the first cleaning roller, which effectively removes residual iron filings and improves the cleaning efficiency and effect. The second cleaning roller cleans the iron filings gathered at the bottom and discharges them out of the cooling box through the discharge port, effectively preventing the secondary mixing of the lubricating oil and the iron filings and maintaining the cleanliness of the lubricating oil. The design of the entire adjustment assembly is closely connected with the roller screw and the transmission assembly. The rotation of the cleaning roller is driven by the rotation of the roller screw, which improves work efficiency and reduces the trouble of manual operation. Example

[0062] In the above embodiment, the iron filings on the electromagnet 2121 are cleaned by the first cleaning roller 226. However, when in use, the electromagnet 2121 is designed to be curved, and the first cleaning roller 226 cannot effectively clean the corners. Therefore, the embodiment of the present application optimizes the first cleaning roller 226 based on the above embodiment.

[0063] In this embodiment, an air bag corresponding to the electromagnet 2121 is provided on the first cleaning roller 226, and a cleaning sponge 2261 is wrapped outside the air bag, and a control component corresponding to the air bag is provided in the cooling box 2;
