Description

[0003] The existing motor seat has a relatively simple function and can only be used to fix the motor. When the motor is running under high load, a large amount of heat will be generated inside the motor. In the existing technology, this problem is generally solved by only using the heat dissipation fins on the surface of the motor to dissipate heat from the motor. However, this method has limited heat dissipation and cooling capabilities.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1 to 7 , the present invention provides a technical solution:

[0031] A motor base for a numerically controlled machine tool comprises a base body 1 with a U-shaped structure and a cover plate 2 fixed to the top of the base body 1 with screws. A motor body 7 is placed between the base body 1 and the cover plate 2. An output shaft 14 is fixed to the front end of the motor body 7. The output shaft 14 passes through the front end of the base body 1 and extends to the front side of the base body 1. Shock absorbers are provided on both sides of the motor body 7 and the base body 1.

[0032] The shock absorber includes a plurality of heat sinks 8 fixedly connected to the inner wall of the base body 1 at equal distances, and a plurality of heat sinks 9 fixedly connected to both sides of the motor body 7 at equal distances. The heat sinks 8 and the heat sinks 29 are distributed at an inclined angle, and the heat sinks 8 and the heat sinks 29 are plugged into and fitted with each other, with a staggered distribution design, and the heat sinks 8 and the heat sinks 29 are made of elastic heat-conducting metal material. Bolts 3 are symmetrically provided on the top of the cover plate 2, and the bolts 3 are threadedly connected to the cover plate 2. A rubber block is fixed to the bottom of the bolt 3, and the bottom of the bolt 3 is fitted to the upper end face of the motor body 7 through the rubber block.

[0033] Specifically, air cooling components 4 are provided on both sides of the base body 1 and the corresponding positions on the upper end surface of the cover plate 2. A circulating water cooling box 10 is provided on the front end surface of the base body 1 at the lower side of the output shaft 14. Pipe three 11 and pipe four 12 are symmetrically connected and fixed on both sides of the outside of the circulating water cooling box 10, and pipe three 11 is located on the upper side of pipe four 12. The interior of the heat sink 8 is a hollow structure design. Several heat sinks 8 are connected end to end, and the rear ends of the heat sinks 8 on both sides are connected and fixed with pipe two. 6. The front ends of the heat sinks 8 on both sides are connected to the circulating water cooling box 10 through the pipe 4 12. The air cooling assembly 4 includes through holes opened on both sides of the base body 1 and the cover plate 2. The middle part of the heat sink 8 is exposed in the through holes. A driving box 22 with a cylindrical structure is provided in the through holes. The outer side of the driving box 22 is rotatably connected to the fixed disk 15. The inside of the driving box 22 is rotatably connected to the connecting shaft 19. One end of the connecting shaft 19 is rotatably connected to the inner wall of the driving box 22, and the other end is fixedly connected to the fixed disk 15.

[0034] The outer ring of the fixed disk 15 is equidistantly fixedly connected with fan blades 16, the outer ring of the connecting shaft 19 is equidistantly fixedly connected with turbine blades 18, and the outer ring of the driving box 22 is equidistantly fixed with four groups of pipes 5, of which two symmetrically distributed pipes 5 are connected to the interior of the driving box 22, the pipes 15 in the air-cooling components 4 on both sides of the base body 1 and the pipes 15 in the air-cooling components 4 on the cover plate 2 are connected to each other, and the two pipes 3 11 extend through the interior of the base body 1 and are connected to one end of the pipe 1 5.

[0035] By adopting the above technical solution, the cooling water is sucked into the circulating water cooling box 10 through the right side pipe three 11 and pipe four 12. The water discharged from pipe three 11 enters pipe one 5 and flows into the drive box 22, driving the turbine blades 18 to rotate, driving the fixed disk 15 and the fan blades 16 to rotate, sucking the air inside the machine base body 1, so that the outside air enters the machine base body 1 to dissipate heat for the motor body 7. The outside air entering the machine base body 1 can also dissipate heat to the heat sink one 8 and the heat sink two 9.

[0036] Specifically, a semicircular groove is provided on the upper side of the circulating water cooling box 10, and a magnetic turntable 13 is rotatably connected in the semicircular groove. The magnetic turntable 13 is sleeved and fixed on the outside of the motor output shaft 14, and a strong magnet 17 is embedded in the inner edge of the magnetic turntable 13. The interior of the circulating water cooling box 10 is movably connected to an air plug plate 20, and the air plug plate 20 is fitted with the inner wall of the circulating water cooling box 10 on all sides, and the top of the air plug plate 20 is fitted with the semicircular groove. An electromagnetic block 21 is embedded in the top of the air plug plate 20, and the pipe three 11 and the pipe four 12 are connected to the inside of the circulating water cooling box 10, and the connections between the pipe three 11, the pipe four 12 and the circulating water cooling box 10 are all built-in with a one-way valve.

[0037] By adopting the above technical solution, the external controller controls the electromagnetic block 21 on the upper side of the air plug plate 20 in the circulating water cooling box 10 to conduct electricity and generate magnetic force. The magnetic force on the upper end surface of the electromagnetic block 21 and the magnetic force on the lower end surface of the strong magnet 17 in the magnetic turntable 13 repel each other. Therefore, when the motor body 7 rotates through the output shaft 14, driving the magnetic turntable 13 to rotate, when the strong magnet 17 in the magnetic turntable 13 approaches the electromagnetic block 21 on the air plug plate 20, the air plug plate 20 is driven to rotate in the circulating water cooling box 10 through magnetic repulsion. The box 10 moves downward to squeeze the spring at the bottom of the circulating water cooling box 10 and the air plug plate 20, and also squeezes the cooling water under the air plug plate 20. At this time, the cooling water is discharged through the pipe three 11 and the pipe four 12 on the left side of the circulating water cooling box 10 under the action of the one-way valve. Then, when the magnetic turntable 13 continues to rotate, the strong magnet 17 and the electromagnetic block 21 are misaligned, and the repulsive force is small. Under the action of the spring, the air plug plate 20 moves upward, and the cooling water is sucked into the circulating water cooling box 10 through the pipe three 11 and the pipe four 12 on the right side.

[0038] Working principle: When working, the user first places the motor body 7 in the base body, aligns the gap between the heat sink 2 9 and the adjacent heat sink 1 8, and gently pushes the motor body 7 from the back to the front into the inside of the base body 1. At this time, the heat sink 1 8 and the heat sink 2 9 fit each other, and the output shaft 14 of the motor body 7 passes through the hole reserved on the front side of the base body. Then the user takes the tool to screw the bolt 3, and the bolt 3 is screwed down until the rubber block at the bottom of the bolt 3 presses down against the upper end surface of the motor body 7. Then continue to screw the bolt 3 to squeeze the motor body 7 downward, so that the heat sink 2 9 on both sides squeeze the heat sink 1 8. The heat sink 1 8 and the heat sink 2 9 are slightly bent and deformed to accumulate elastic potential, so that the vibration generated by the subsequent operation of the motor body 7 can be damped by the elastic force of the heat sink 1 8 and the heat sink 2 9.

[0039] Then the user sleeves and fixes the magnetic turntable 13 on the outside of the output shaft 14, and the base body 1 has a built-in temperature sensor. When the temperature of the motor body 7 rises and exceeds the preset temperature, the external controller controls the electromagnetic block 21 on the upper side of the air plug plate 20 in the circulating water cooling box 10 to conduct electricity and generate magnetic force. The magnetic force of the upper end surface of the electromagnetic block 21 and the magnetic force of the lower end surface of the strong magnet 17 in the magnetic turntable 13 repel each other. Therefore, when the motor body 7 rotates through the output shaft 14, driving the magnetic turntable 13 to rotate, when the strong magnet 17 in the magnetic turntable 13 approaches the electromagnetic block 21 on the air plug plate 20, the air plug plate 20 is driven downward in the circulating water cooling box 10 through magnetic repulsion, squeezing the circulating water cooling box 10 and the spring at the bottom of the air plug plate 20, and also squeezing the air plug plate 20. The cooling water under the cooling water, at this time, is discharged through the pipe three 11 and the pipe four 12 on the left side of the circulating water cooling box 10 under the action of the one-way valve, and then when the magnetic turntable 13 continues to rotate, the strong magnet 17 is misaligned with the electromagnetic block 21, and the repulsive force is small. Under the action of the spring, the air plug plate 20 moves up, and the cooling water is sucked into the circulating water cooling box 10 through the pipe three 11 and the pipe four 12 on the right side. The water discharged from the pipe three 11 enters the pipe one 5 and flows into the drive box 22, driving the turbine blades 18 to rotate, driving the fixed disk 15 and the fan blades 16 to rotate, sucking the air inside the base body 1, so that the outside air enters the base body 1 to dissipate heat for the motor body 7. The outside air entering the base body 1 can also dissipate heat to the heat sink one 8 and the heat sink two 9;

[0040] The cooling water in the pipe 4 12 enters the heat sink 1 8 and passes through the heat sink 2 9 to realize a complete water cooling cycle, thereby further improving the heat dissipation and cooling of the motor body 7 .
