Description

Technical Field

[0001] This utility model relates to the field of electric spindle equipment technology, and specifically to an electric spindle cooling jacket. Background Technology

[0002] Electric spindles are mainly used in CNC machine tools. They achieve the working principle of mechatronics by installing an electric motor inside the spindle. Compared with traditional CNC machine tool spindles, electric spindles have advantages such as compact structure, low noise, high mechanical efficiency, high precision, and low vibration amplitude, making them more suitable for the working requirements of current CNC machine tools.

[0003] After prolonged use, the bearings of an electric spindle will lose their original precision and performance due to wear, increasing friction and generating more heat, which can lead to overheating. Existing electric spindles often use water circulation cooling. However, during the operation of the circulating water, scale, dirt, corrosion, and microbial sludge will be generated, which will significantly reduce the cooling and heat dissipation effect. Once the inner wall of the cooling channel of the existing cooling equipment is contaminated with scale and dirt, it is difficult to clean and maintain the inner wall. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an electric spindle cooling sleeve to solve the problems mentioned in the background art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An electric spindle cooling sleeve includes an electric spindle housing. The outer wall of the electric spindle housing is fixedly provided with annular cooling fins that are evenly distributed. The outer wall of the annular cooling fins is fixedly provided with annular cooling sleeves that are evenly distributed through openings. A cooling tube is inserted into the inner wall of the cooling sleeve. The top and bottom outer walls of the cooling tube are fixedly provided with pipe joints through openings.

[0007] As a preferred embodiment of the electric spindle cooling sleeve, an interconnecting hose is connected between adjacent pipe joints to facilitate the connection of adjacent cooling tubes. The tops of the two cooling tubes are connected to a connecting pipe via pipe joints to facilitate connection with a cooling water circulation pump.

[0008] As a preferred embodiment of the electric spindle cooling sleeve, the outer wall of the cooling tube is fitted with the inner wall of the cooling sleeve, and a limiting ring is fixedly provided on the top outer wall of the cooling tube to prevent the cooling tube from falling off the inner wall of the cooling sleeve.

[0009] As a preferred embodiment of the electric spindle cooling sleeve, the top outer wall of the electric spindle housing has equally spaced threaded fixing holes, and the inner wall of the threaded fixing holes is equipped with matching bolts, which facilitates fixing the present invention in a designated position.

[0010] As a preferred embodiment of the electric spindle cooling sleeve, the outer wall of the annular cooling fins is fitted with a sealing cover, and the two outer walls of the sealing cover are respectively fixed with an air inlet frame and an air outlet frame through openings.

[0011] As a preferred embodiment of the electric spindle cooling jacket, the inner wall of the air intake frame is equipped with equally spaced air intake fans. The air intake fans are connected to a power switch via wires, and the power switch is connected to a power cord. The inner wall of the exhaust frame is equipped with an exhaust grille. The air intake fans can input external gas into the sealed housing. The gas entering the sealed housing can dissipate heat from the annular cooling fins. The gas entering the sealed housing is discharged through the exhaust frame.

[0012] As a preferred embodiment of the electric spindle cooling sleeve, the annular cooling fins, cooling sleeve, and cooling tube are all made of aluminum.

[0013] The beneficial effects of this utility model are:

[0014] This invention allows for the removal of the connecting hoses at both ends of adjacent cooling tubes, enabling the cooling tubes to be pulled out from the inner wall of the cooling sleeve. This facilitates the rinsing and cleaning of the inner wall of the cooling tubes. After cleaning, the cooling tubes are inserted back into the inner wall of the cooling sleeve, and the connecting hoses are then reconnected to the cooling tubes. This facilitates the disassembly and installation of the cooling tubes and makes it easy to clean scale, dirt, corrosion, and microbial sludge adhering to the inner wall of the cooling tubes, thus avoiding any impact on the cooling effect on the electric spindle.

The tops of the two cooling pipes 4 are connected to a connecting pipe 8 via pipe joints 6, which facilitates connection to the cooling water circulation pump. The outer wall of the cooling pipe 4 fits against the inner wall of the cooling sleeve 3. A limiting ring 5 is fixedly provided on the top outer wall of the cooling pipe 4 to prevent the cooling pipe 4 from falling off the inner wall of the cooling sleeve 3. The top outer wall of the electric spindle housing 1 has equally spaced threaded fixing holes 9, and the inner wall of the threaded fixing holes 9 is equipped with matching bolts to facilitate fixing the present invention in a designated position.

[0030] Example 3

[0031] Based on Embodiment 1, in this embodiment, the outer wall of the annular cooling fin 2 is fitted with a sealing cover 10. The two outer walls of the sealing cover 10 are respectively fixed with an air inlet frame 11 and an exhaust frame 12 through openings. The inner wall of the air inlet frame 11 is equipped with an air intake fan 13 that is evenly distributed. The air intake fan 13 is connected to a power switch through a wire, and the power switch is connected to a power cord. The inner wall of the exhaust frame 12 is equipped with an exhaust grille 14.

The gas entering the sealing cover 10 is discharged through the exhaust frame 12.

[0032] Working principle and usage process of this utility model:

[0033] Refer to the instruction manual appendix Figure 1-4In use, the electric spindle cooling sleeve of this utility model is first installed on the designated position on the CNC machine tool through the threaded fixing hole 9 on the top of the electric spindle housing 1. During the operation of the electric spindle, circulating water is input into the connecting pipe 8 through the circulating pump, and then into the cooling tube 4 through the annular cooling fins 2. Adjacent cooling tubes 4 are connected by interconnecting hoses 7. Circulating water flows in the cooling tube 4. As a large amount of heat is generated inside the electric spindle housing 1 during operation, the heat is conducted to the cooling sleeve 3 through the annular cooling fins 2, and then to the cooling tube 4 through the cooling sleeve 3. The circulating water in the cooling tube 4 absorbs the heat, causing the electric spindle housing 1 to cool down rapidly. At the same time, the intake fan 13 installed in the intake frame 11 introduces external air into the sealing cover 10. The gas passes through the outer wall of the annular cooling fin 2, further cooling the annular cooling fin 2, which is beneficial to improving the cooling effect of this utility model. The gas in the sealed cover 10 is discharged through the exhaust frame 12. With the long-term use of this utility model, scale, dirt, corrosion and microbial slime will be generated on the inner wall of the cooling tube 4. At this time, the connecting hose 7 connected to both ends of the adjacent cooling tube 4 is disassembled, and the cooling tube 4 can be pulled out from the inner wall of the cooling sleeve 3, which is convenient for rinsing and cleaning the inner wall of the cooling tube 4. After cleaning, the cooling tube 4 is inserted into the inner wall of the cooling sleeve 3, and then the connecting hose 7 is connected to the cooling tube 4 to facilitate the disassembly and installation of the cooling tube 4. This makes it convenient to clean the scale, dirt, corrosion and microbial slime adhering to the inner wall of the cooling tube 4, and avoid affecting the cooling effect on the electric spindle.

[0034] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
