Description

[0002] As the driving source of CNC machine tools, motors are mainly divided into two types: vertical and horizontal. During use, they are usually installed on motor mounts, and the quality of the installation environment is one of the important factors affecting their working quality.

[0003] Existing motor mounts have a relatively simple function, serving only as a means of fixing the motor. When the motor is operating under high load, a large amount of heat is generated inside the motor. Current technologies generally address this issue by using heat dissipation fins on the motor surface to dissipate heat. However, this method of heat dissipation and cooling is limited, and in dusty environments, dust accumulates on the heat dissipation fins on the motor surface, forming a heat insulation layer, which further increases the likelihood of high-temperature damage to the motor and cannot guarantee good temperature operating conditions for the motor.

[0004] To address this, a CNC machine tool motor mount is proposed. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 7 The present invention provides a technical solution:

[0031] A CNC machine tool motor base includes a U-shaped machine base body 1 and a cover plate 2 that is screwed and fixed to the top of the machine base body 1. A motor body 7 is placed between the machine 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 machine base body 1 and extends to the front side of the machine base body 1. Shock-absorbing components are provided on both sides of the motor body 7 and the machine base body 1.

[0032] The shock-absorbing component includes several heat sinks 8 that are fixedly connected at equal intervals to the inner wall of the base body 1. Several heat sinks 9 are fixedly connected at equal intervals to both sides of the motor body 7. The heat sinks 8 and 9 are distributed at an inclined angle. The heat sinks 8 and 9 are interlocked and attached to each other, with a staggered distribution design. The heat sinks 8 and 9 are made of elastic thermally conductive metal. The top of the cover plate 2 is symmetrically provided with bolts 3, and the bolts 3 are threaded to the cover plate 2. A rubber block is fixed to the bottom of the bolts 3, and the bottom of the bolts 3 is attached to the upper surface 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 on the upper end of the cover plate 2. A circulating water-cooling box 10 is provided on the front end face of the base body 1 below the output shaft 14. Pipes 3 11 and 4 12 are symmetrically connected and fixed on both sides of the circulating water-cooling box 10, with pipe 3 11 located above pipe 4 12. The heat sink 8 has a hollow internal structure, and several heat sinks 8 are connected end to end. Pipes 2 are connected and fixed to the rear ends of the heat sinks 8 on both sides. 6. The front ends of the heat sinks 8 on both sides are connected to the circulating water cooling box 10 through the pipe 12. The air cooling assembly 4 includes through holes 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 hole. A cylindrical drive box 22 is provided in the through hole. A fixed plate 15 is rotatably connected to the outside of the drive box 22. A connecting shaft 19 is rotatably connected to the inside of the drive box 22. One end of the connecting shaft 19 is rotatably connected to the inner wall of the drive box 22, and the other end is fixedly connected to the fixed plate 15.

[0034] Fan blades 16 are fixedly connected to the outer ring of the fixed disk 15 at equal intervals. Turbine blades 18 are fixedly connected to the outer ring of the connecting shaft 19 at equal intervals. Four sets of pipes 5 are fixedly connected to the outer ring of the drive box 22 at equal intervals. Two symmetrically distributed pipes 5 are connected to the inside of the drive box 22. The pipes 5 in the air-cooling components 4 on both sides of the base body 1 and the pipes 5 in the air-cooling components 4 on the cover plate 2 are connected to each other. Two pipes 11 extend through the base body 1 and connect to one end of the pipes 5.

[0035] By adopting the above technical solution, cooling water is drawn into the circulating water cooling box 10 through the right-side pipe 3 11 and pipe 4 12. The water discharged from pipe 3 11 enters pipe 1 5 and flows into the drive box 22, driving the turbine blades 18 to rotate, which in turn drives the fixed disk 15 and the fan blades 16 to rotate, drawing air from the base body 1, so that the outside air can enter the base body 1 to dissipate heat from the motor body 7. The outside air entering the base body 1 can also dissipate heat from the heat sink 1 8 and the heat sink 2 9.

[0036] Specifically, a semi-circular groove is provided on the upper side of the circulating water cooling box 10. A magnetic turntable 13 is rotatably connected in the semi-circular groove. The magnetic turntable 13 is sleeved and fixed outside the motor output shaft 14. A strong magnet 17 is embedded in the inner edge of the magnetic turntable 13. An air plug plate 20 is movably connected inside the circulating water cooling box 10. The air plug plate 20 is fitted to the inner wall of the circulating water cooling box 10 on all four sides, and the top of the air plug plate 20 matches the semi-circular groove. An electromagnetic block 21 is embedded in the top of the air plug plate 20. Pipes 3 11 and 4 12 are connected to the inside of the circulating water cooling box 10, and a one-way valve is built into the connection between pipes 3 11 and 4 12 and the circulating water cooling box 10.

[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 surface of the electromagnetic block 21 and the magnetic force on the lower surface of the strong magnet 17 in the magnetic disk 13 repel each other. Therefore, when the motor body 7 rotates through the output shaft 14 and drives the magnetic disk 13 to rotate, when the strong magnet 17 in the magnetic disk 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 by magnetic repulsion. The downward movement of the box 10 compresses the spring at the bottom of the circulating water cooling box 10 and the air plug plate 20, and also compresses the cooling water under the air plug plate 20. At this time, the cooling water is discharged through the pipe 3 11 and pipe 4 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. When the repulsive force is small, the air plug plate 20 moves upward under the action of the spring, and the cooling water is drawn into the circulating water cooling box 10 through the pipe 3 11 and pipe 4 12 on the right side.

[0038] Working principle: During operation, the user first places the motor body 7 inside the base body, aligns the gaps of the heat sink 2 9 with the adjacent heat sink 1 8, and gently pushes the motor body 7 into the base body 1 from back to front. At this time, the heat sink 1 8 and the heat sink 2 9 are in contact with each other. The output shaft 14 of the motor body 7 passes through the pre-drilled hole on the front side of the base body. Then, the user takes a tool and turns the bolt 3. The bolt 3 is turned and moved down until the rubber block at the bottom of the bolt 3 touches the upper surface of the motor body 7. Then, the user continues to turn the bolt 3 and presses the motor body 7 down, so that the heat sink 2 9 on both sides presses the heat sink 1 8. The heat sink 1 8 and the heat sink 2 9 are slightly bent and deformed to store elasticity, so that the vibration generated by the motor body 7 during operation can be damped by the elastic force of the heat sink 1 8 and the heat sink 2 9.

[0039] Then, the user attaches a fixed magnetic turntable 13 to the outside of the output shaft 14. The base body 1 has a built-in temperature sensor. When the temperature of the motor body 7 rises above the preset temperature, the external controller controls the electromagnetic block 21 on the upper side of the air plug plate 20 inside the circulating water cooling box 10 to conduct electricity and generate magnetic force. The magnetic force on the upper surface of the electromagnetic block 21 repels the magnetic force on the lower surface of the strong magnet 17 inside the magnetic turntable 13. Therefore, when the motor body 7 rotates through the output shaft 14, driving the magnetic turntable 13 to rotate, when the strong magnet 17 inside the magnetic turntable 13 approaches the electromagnetic block 21 on the air plug plate 20, the magnetic repulsion drives the air plug plate 20 to move downwards within the circulating water cooling box 10, compressing the spring at the bottom of the circulating water cooling box 10 and the air plug plate 20, thus compressing the air plug plate 20 as well. The cooling water is discharged through pipes 11 and 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. When the repulsive force is small, the air plug plate 20 moves upward under the action of the spring. The cooling water is then drawn into the circulating water cooling box 10 through pipes 11 and 12 on the right side. The water discharged from pipe 11 enters pipe 5 and flows into the drive box 22, driving the turbine blades 18 to rotate. This drives the fixed disk 15 and the fan blades 16 to rotate, drawing air from the base body 1. This allows outside air to enter the base body 1 to cool the motor body 7. The outside air entering the base body 1 can also cool the heat sink 8 and the heat sink 9.

[0040] Cooling water from pipe 412 enters heat sink 18 and passes through heat sink 29 to achieve a complete water cooling cycle, further improving the heat dissipation and cooling of the motor body 7.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
