[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-4 ,in, Figure 1 A front view schematic diagram of a preferred embodiment of the spindle device of a CNC cylindrical grinding machine provided by this utility model; Figure 2 This is a rear sectional view of the axle box of this utility model. Figure 3 This is a rear view structural diagram of the axle box of this utility model; Figure 4 for Figure 2 The diagram shows an enlarged view of part A.

[0023] The spindle assembly of a CNC cylindrical grinding machine includes: a spindle box 2 mounted on the body 1 of the CNC cylindrical grinding machine, the spindle box 2 being divided into a first mounting chamber 3 and a second mounting chamber 4; a mounting base 5 fixed in the first mounting chamber 3, on which a spindle 6 is mounted via bearings; a motor 7 fixed in the second mounting chamber 4, the output shaft of the motor 7 extending into the first mounting chamber 3; gears 8 respectively fixed to the output shaft of the motor 7 and the spindle 6 and meshing with each other; and a mounting box fixed on the spindle box 2, the mounting box having... A filter box 9 is provided; a liquid extraction pipe 10 is fixedly connected to the filter box 9, and the liquid inlet end of the liquid extraction pipe 10 is connected to the first installation chamber 3 for pumping lubricating oil. By separating the first installation chamber 3 and the second installation chamber 4 in the shaft box 2, the main shaft 6 and the motor 7 are installed separately to avoid mutual interference. With the filter box 9 and the liquid extraction pipe 10, in conjunction with the oil extraction mechanism, the lubricating oil containing impurities in the first installation chamber 3 can be extracted, filtered, and returned to the first installation chamber 3, realizing the recycling of lubricating oil and reducing lubricating oil consumption and production costs.

[0024] The oil extraction mechanism includes: a mounting shell 12 fixed inside the mounting box, with a first rotating rod 18 assembled inside the mounting shell 12 via a sealed bearing; an impeller 20 fixed on the first rotating rod 18; a connecting pipe 13 fixedly connected to the mounting shell 12, the inlet end of the connecting pipe 13 being connected to the filter box 9; and a return pipe 14 fixedly connected to the outlet of the mounting shell 12, the outlet end of the return pipe 14 extending into the first mounting chamber 3. The mounting shell 12, the first rotating rod 18, and the impeller 20 in the oil extraction mechanism cooperate with each other. The rotation of the impeller 20 generates suction, which can send the lubricating oil filtered in the filter box 9 back to the first mounting chamber 3 through the connecting pipe 13 and the return pipe 14, ensuring the smooth circulation path of the lubricating oil, making the lubricating oil circulation process stable and efficient, and further reducing the waste of lubricating oil.

[0025] The oil extraction mechanism also includes a transmission mechanism, which comprises: a transmission rod 15 mounted in the mounting box via bearings; pulleys 16 are fixedly mounted on both the transmission rod 15 and the output shaft of the motor 7; and transmission belts 17 are fitted onto the two pulleys 16 for transmission; and first bevel teeth 19 fixed to the transmission rod 15 and the first rotating rod 18 respectively and meshing with each other. The transmission mechanism uses the pulleys 16 and transmission belts 17 on the output shaft of the motor 7 to transmit power to the transmission rod 15, and then the first bevel teeth 19 drive the first rotating rod 18 to rotate, thereby driving the impeller 20 to work. This design cleverly utilizes the power of the motor 7, eliminating the need for an additional power source to drive the oil extraction mechanism, saving energy, simplifying the device structure, reducing costs, and ensuring that the oil extraction mechanism and the main shaft drive system work together.

[0026] The axle box 2 is equipped with an exhaust mechanism, which includes: an exhaust pipe 21 fixedly connected to the top of the second mounting chamber 4; a second rotating rod 22 mounted in the exhaust pipe 21 via a bearing seat, with a fan blade 23 fixed on the second rotating rod 22; and second bevel teeth 24 fixed to the second rotating rod 22 and the transmission rod 15 and meshing with each other. The exhaust mechanism drives the second bevel teeth 24 through the transmission rod 15, thereby causing the second rotating rod 22 and the fan blade 23 to rotate and expel the hot air from the second mounting chamber 4. This effectively prevents the performance of the motor 7 from deteriorating due to excessively high operating ambient temperature.

[0027] An air inlet is provided on one side of the second installation chamber 4, and a dust filter plate 25 is provided inside the air inlet.

[0028] The filter box 9 is equipped with a filter plate 11 for filtering impurities. The top of the filter box 9 is equipped with a removable sealing cover, and a handle is fixedly installed on the top of the sealing cover. A dust filter plate 25 is installed at the air inlet on one side of the second installation chamber 4. When the exhaust mechanism is working to allow air circulation, it can filter out external dust and prevent dust from entering the second installation chamber 4 and affecting the normal operation of the motor 7.

[0029] Both the connecting pipe 13 and the liquid extraction pipe 10 are equipped with electromagnetic valves.

[0030] The working principle of the CNC cylindrical grinding machine spindle device provided by this utility model is as follows:

[0031] In operation, the motor 7 starts, and its output shaft drives the pulley 16 to rotate. The power is transmitted to the transmission rod 15 via the transmission belt 17. The transmission rod 15 then drives the first rotating rod 18 to rotate via the first bevel gear 19, thereby causing the impeller 20 to rotate within the mounting housing 12. The rotation of the impeller 20 generates suction, which draws the lubricating oil containing impurities from the first mounting chamber 3 to the filter box 9 through the liquid extraction pipe 10. After the lubricating oil passes through the filter plate 11 to remove impurities, it flows into the connecting pipe 13 and is finally returned to the first mounting chamber 3 via the return pipe 14, thus realizing the recycling of lubricating oil and reducing its consumption.

[0032] Simultaneously, the output shaft of motor 7 drives the main shaft 6 to rotate via meshing gears 8, performing grinding operations. During the operation of motor 7, when the transmission rod 15 rotates, it also drives the second rotating rod 22 to rotate via the second bevel gear 24, causing the fan blade 23 to rotate within the exhaust pipe 21, expelling hot air from the second mounting chamber 4. The air inlet on one side of the second mounting chamber 4, in conjunction with the dust filter plate 25, allows clean outside air to enter when the fan blade 23 exhausts air, maintaining air circulation within the second mounting chamber 4 and preventing excessive internal temperature from affecting the performance of motor 7. The dust filter plate 25 also prevents dust from entering and affecting equipment operation. The first mounting chamber 3, as a sealed space, continuously stores lubricating oil, submerging the main shaft 6 and mounting base 5, providing excellent lubrication and ensuring stable operation of the main shaft. The reserved oil drain and fill ports facilitate lubricating oil replacement during later maintenance, eliminating the need for frequent lubricating oil changes and effectively improving production efficiency.

[0033] Compared with related technologies, the CNC cylindrical grinding machine spindle device provided by this utility model has the following beneficial effects:

[0034] This utility model provides a spindle device for a CNC cylindrical grinding machine. By dividing the spindle box 2 into a first mounting chamber 3 and a second mounting chamber 4, the spindle 6 and the motor 7 can be installed separately to avoid mutual interference. A filter box 9, a liquid extraction pipe 10, and an oil extraction mechanism are provided to extract, filter, and recycle the lubricating oil containing impurities in the first mounting chamber 3, thereby reducing lubricating oil consumption and production costs. The transmission mechanism uses the power of the motor 7 to drive the oil extraction mechanism, eliminating the need for an additional power source, saving energy and simplifying the structure.

In terms of the technical aspects of this design principle, the setting of the power mechanism, power supply system and control system of the device is not fully described. However, those skilled in the art who understand the principle of the above utility model can clearly understand the specific details of its power mechanism, power supply system and control system.
