It is responsible for driving the spindle to rotate, thereby realizing the machining of workpieces. The publication number CN213135975U discloses a quick-release spindle motor for a numerically controlled machine tool, including a motor. The motor is a servo motor. A control terminal is fixed on the top surface of the motor, and the control terminal is electrically connected to the motor. A driving gear is embedded at the movable end of the motor, and the driving gear is movably connected to the motor. Fixing plates are welded on both sides of the motor. Clamping pieces are embedded on the surface of the fixing plates, and the fixing plates are embedded inside the clamping pieces, and the fixing plates are slidably connected to the clamping pieces. A fixing bracket is fixed on the side of the clamping piece away from the motor. In this utility model, the design of the fixing plate and the clamping piece realizes the simple fixation of the motor. When the motor fails, it is convenient for maintenance personnel to disassemble, repair and install, which brings convenience to the maintenance work. The design of the buffer pad and the gasket realizes the buffering of the motor and the fixing bracket. When the motor is working, the vibration at the connection is reduced, and the loosening of the motor caused by severe vibration is prevented, ensuring the stability of the motor fixation. However, when disassembling this spindle motor, tools are still needed to turn the locking parts, and the use of tools greatly reduces the disassembly efficiency of the spindle motor.

[0021] Embodiment 1

[0022] Please refer to Figures 1-3, the present utility model provides a technical solution: a numerically controlled machine tool spindle motor convenient for maintenance, including a mounting plate 1 and a spindle motor body 12. A first chute 2 is penetrated and opened at the top of the mounting plate 1. A threaded rod 3 is installed inside the first chute 2. A slider 4 is threadedly connected to the outer wall of the threaded rod 3. A connecting plate 5 is fixedly installed at the bottom of the slider 4. Rotating handles 6 are symmetrically and fixedly installed on the outer wall of one end of the threaded rod 3. A second chute 7 is opened at the bottom of the connecting plate 5. A bidirectional lead screw 8 is installed inside the second chute 7. Slide plates 9 are symmetrically threadedly connected to the outer wall of the bidirectional lead screw 8. Limiting insertion blocks 10 are fixedly installed on the inner sides of the slide plates 9. Rotating handles 11 are symmetrically and fixedly installed on the outer wall of one end of the bidirectional lead screw 8. A fixing ring 13 is fixedly installed on the outer wall of the spindle motor body 12. Limiting grooves 14 are symmetrically opened on the outer wall of the fixing ring 13. By setting structures such as the first chute 2, the threaded rod 3, the slider 4, the connecting plate 5, the rotating handle 6, the second chute 7, the bidirectional lead screw 8, the slide plate 9, the limiting insertion block 10, the rotating handle 11, the fixing ring 13 and the limiting groove 14, the position adjustment effect of the spindle motor body 12 is improved, facilitating the operator to appropriately adjust the position of the spindle motor body 12 according to the operation situation, effectively avoiding that the inability to adjust the position of the spindle motor body 12 will affect the use effect of the numerically controlled machine tool. At the same time, this structure can quickly disassemble the faulty spindle motor body 12 from the connecting plate 5, thereby facilitating the operator to repair it and effectively avoiding the need to use tools to turn the locking parts during disassembly.

[0023] Please refer to Figures 1-3 , the threaded rod 3 is connected to the mounting plate 1 through a bearing, and the bidirectional lead screw 8 is connected to the connecting plate 5 through a bearing. Connecting through a bearing improves the rotation effect of the threaded rod 3 and the bidirectional lead screw 8. The slider 4 is slidably connected to the first chute 2, and the slide plate 9 is slidably connected to the second chute 7. The sliding connection improves the limiting effect during the adjustment of the slider 4 and the slide plate 9. The limiting insertion block 10 is slidably connected to the limiting groove 14. The sliding connection improves the fixing effect of the fixing ring 13 and the spindle motor body 12. Mounting holes 20 are symmetrically penetrated and opened at the top of the mounting plate 1, and the number of the mounting holes 20 is four groups. The four groups of mounting holes 20 facilitate the fixing of the mounting plate 1 to the numerically controlled machine tool.

[0024] Embodiment Two

[0025] Please refer to Figure 1 and Figure 4, a fixed shell 15 is fixedly installed at the bottom of the connecting plate 5. Through holes 16 are evenly penetrated through the outer wall and the bottom of the fixed shell 15. A fixed plate 17 is fixedly installed inside the fixed shell 15. A motor 18 is fixedly installed inside the fixed plate 17. An output end of the motor 18 is fixedly installed with a heat dissipation fan blade 19. By starting the motor 18, when the motor 18 works, it will drive the heat dissipation fan blade 19 to rotate. During the rotation of the heat dissipation fan blade 19, the heat generated by the main shaft motor body 12 will be dissipated from the through holes 16, thereby improving the heat dissipation effect of the main shaft motor body 12, effectively avoiding the main shaft motor body 12 from being prone to overheating, and extending its service life.

[0026] Working principle: When in use, first install the mounting plate 1 on the numerical control machine tool. If the use position of the main shaft motor body 12 needs to be adjusted after installation, the turning handle one 6 can be rotated. By driving the threaded rod 3 to rotate inside the mounting plate 1 through the turning handle one 6, the slider 4 will be driven to slide inside the chute one 2 during the rotation of the threaded rod 3. During the sliding of the slider 4, the connecting plate 5 and the main shaft motor body 12 will be driven to move together, thereby improving the position adjustment effect of the main shaft motor body 12, facilitating the operator to appropriately adjust the position of the main shaft motor body 12 according to the operation situation, and effectively avoiding that the inability to adjust the position of the main shaft motor body 12 will affect the use effect of the numerical control machine tool. When the main shaft motor body 12 fails and needs to be disassembled and repaired, first rotate the turning handle two 11. By driving the bidirectional lead screw 8 to rotate through the turning handle two 11, the two groups of slide plates 9 will be driven to slide in opposite directions inside the chute two 7 during the rotation of the bidirectional lead screw 8. During the sliding of the two groups of slide plates 9, the two groups of limit insertion blocks 10 will be driven to move away from the limit groove 14. After moving away, the main shaft motor body 12 can be removed for repair. When the main shaft motor body 12 is in use, the motor 18 can be started. When the motor 18 works, it will drive the heat dissipation fan blade 19 to rotate. During the rotation of the heat dissipation fan blade 19, the heat generated by the main shaft motor body 12 will be dissipated from the through holes 16, thereby improving the heat dissipation effect of the main shaft motor body 12, effectively avoiding the main shaft motor body 12 from being prone to overheating, and extending its service life.
