Description
A novel horizontal lathe electric spindle Technical Field
[0001] This utility model relates to the field of electric spindle technology, and in particular to a novel horizontal lathe electric spindle. Background Technology
[0002] With the continuous development of the manufacturing industry and the improvement of automation level, CNC machine tools are increasingly widely used in various processing fields. Horizontal lathes, as an important processing equipment, are widely used in metal processing, machinery manufacturing and other industries. The electric spindle is an important component of horizontal lathes, mainly used to drive cutting tools for cutting processing.
[0003] Traditional horizontal lathe electric spindles generate a large amount of heat during high-speed operation, requiring effective cooling. Currently, the common cooling method involves a water circulation system that flows cooling water through the spindle housing. However, due to the low heat exchange efficiency between the cooling water and the spindle, the generated heat cannot be quickly and effectively removed, resulting in poor cooling performance. This affects the spindle's performance and stability, shortening its lifespan. In the traditional installation process, the spindle is typically rotatably mounted on a base, which is then secured to the lathe using bolts and nuts. When the spindle malfunctions or needs replacement, multiple bolts and nuts must be removed one by one to remove the base, and then all bolts and nuts must be reinstalled after replacement. This process is time-consuming and reduces work efficiency. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel horizontal lathe electric spindle.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A novel horizontal lathe electric spindle includes a spindle body with a water tank fixed to one end. A storage cavity is formed inside the spindle body. A second circular hole is formed at the midpoint between adjacent ends of the spindle body and the water tank, and both second circular holes communicate with the storage cavity. A water supply mechanism for supplying water to the water tank is provided on the outer wall of the water tank. A first annular seat is fitted onto the outer wall of the water tank. A second annular seat is provided at one end of the first annular seat. Multiple fixing mechanisms for fixing the first annular seat are arranged in a circular pattern at equal intervals on the outer wall of the second annular seat. A U-shaped frame is fixed to one end of the second annular seat. A sleeve is passed through the side wall of the U-shaped frame. A support plate is fitted onto the side wall of the sleeve. A rotating mechanism for rotating the sleeve is provided on the side wall of the support plate. During use, this device connects to an external water source through the water supply mechanism and delivers cold water into the storage cavity during operation. This helps to quickly and effectively remove the heat generated during cutting, keeping the spindle body temperature at a low level, improving the cooling effect, enhancing the performance and stability of the spindle body, and thus extending its service life.
[0007] Preferably, the fixing mechanism includes a third through hole, which is formed on the outer wall of the second annular seat. One end of the second annular seat has the second through hole through it, and the second and third through holes communicate with each other. A sleeve is fixed to the side wall of the third through hole. A circular slider is slidably connected to the inner wall of the sleeve. A pin is fixed to one end of the circular slider, and one end of the pin passes through one end of the sleeve. A connecting rod is fixed to the other end of the circular slider, and one end of the connecting rod passes through the other end of the sleeve. A spring is sleeved on the side wall of the connecting rod. A column is fixed to one end of the first annular seat, and the column is adapted to the second through hole. A first through hole is formed through the side wall of the column, and the first through hole and the pin are adapted to each other. When installing the main spindle body, the water tank and the main spindle body are fixed in advance, and the support plate is installed on the horizontal lathe. First, pull multiple connecting rods so that multiple circular sliders move along the inner sidewalls of multiple sleeves until multiple pins retract into the sleeves. At this time, multiple columns are inserted into the second through holes. Then, release multiple connecting rods. Under the reaction of multiple compressed springs, multiple circular sliders are pushed to move in the opposite direction until multiple pins enter the first through holes. At this time, the first and second annular seats are in a fixed state, thus completing the installation of the water tank. Installation does not require bolt and nut tightening, which is simple, saves time, and improves work efficiency.
[0008] Preferably, the rotating mechanism includes a motor, which is fixed to the outer wall of the support plate. The output shaft of the support plate is sleeved with a first bevel gear, and the outer wall of the sleeve is sleeved with a second bevel gear. The second bevel gear and the first bevel gear mesh, driving the motor to rotate the first bevel gear. The second bevel gear and the sleeve, in conjunction with the second bevel gear, drive the U-shaped frame to rotate. The rotation of the U-shaped frame drives the second annular seat and the first annular seat to rotate, thereby driving the water tank and the main shaft body to rotate, enabling cutting operations.
[0009] Preferably, the water supply mechanism includes a connecting pipe that passes through the middle of the other end of the water tank. A rotary joint is installed at one end of the connecting pipe, and a flexible hose is installed at one end of the rotary joint. One end of the flexible hose passes through the inside of a sleeve. Multiple first circular holes are evenly spaced on the outer wall of the other end of the spindle body, and these holes communicate with the storage cavity, connecting the flexible hose to an external water source. Cold water is supplied to the water tank through the flexible hose and the connecting pipe, and then enters the storage cavity through two second circular holes to cool the spindle body. Simultaneously, the cold water is sprayed onto the cutting blades through the multiple first circular holes to cool them as well. This ensures that the cold water inside the storage cavity is constantly circulating, effectively and quickly removing the generated heat and maintaining a low surface temperature in the water tank. This improves the cooling effect, thereby enhancing the performance and stability of the spindle body and extending its service life.
[0010] The beneficial effects of this utility model are as follows:
[0011] 1. During use, this device connects to an external water source via a water supply mechanism and delivers cold water into the storage chamber during operation. This helps to quickly and effectively remove the heat generated during cutting, keeping the spindle body temperature at a low level. This improves the cooling effect, enhances the performance and stability of the spindle body, and extends its service life.
[0012] 2. By fixing the spindle body and the water tank, and by fixing the first and second annular seats through the fixing mechanism, the installation of the spindle body becomes simple and quick, avoiding the cumbersome bolt and nut tightening method, saving time and improving work efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Referring to Figures 1-6, a novel horizontal lathe electric spindle includes a spindle body 1, a water tank 2 fixed to one end of the spindle body 1, a storage cavity 12 inside the spindle body 1, and second circular holes 14 at the midpoints of adjacent ends of the spindle body 1 and the water tank 2, both of which communicate with the storage cavity 12. A water supply mechanism for supplying water to the water tank 2 is provided on the outer wall of the water tank 2. A first annular seat 3 is fitted onto the outer wall of the water tank 2, and a second annular seat 4 is provided at one end of the first annular seat 3. Multiple fixing mechanisms for fixing the first annular seat 3 are arranged in a circular pattern at equal intervals on the outer wall of the second annular seat 4. The device has a U-shaped frame 5 fixed at one end of the second annular seat 4. A sleeve 6 is provided through the side wall of the U-shaped frame 5. A support plate 7 is fitted on the side wall of the sleeve 6. A rotating mechanism for rotating the sleeve 6 is provided on the side wall of the support plate 7. During use, the device is connected to an external water source through a water supply mechanism and cold water is sent into the storage cavity 12 during operation. This helps to quickly and effectively remove the heat generated during the cutting process, so that the temperature of the spindle body 1 is always maintained at a low temperature, which improves the cooling effect, enhances the performance and stability of the spindle body 1, and extends the service life of the spindle body 1.
[0022] Furthermore, the fixing mechanism includes a third through hole 21, which is formed on the outer wall of the second annular seat 4. One end of the second annular seat 4 has a second through hole 19 extending through it, and the second through hole 19 and the third through hole 21 are connected. A sleeve 20 is fixed to the side wall of the third through hole 21. A circular slider 22 is slidably connected to the inner wall of the sleeve 20. A pin 23 is fixed to one end of the circular slider 22, and one end of the pin 23 passes through one end of the sleeve 20. A connecting rod 24 is fixed to the other end of the circular slider 22, and one end of the connecting rod 24 passes through the other end of the sleeve 20. A spring 25 is sleeved on the side wall of the connecting rod 24. A column 10 is fixed to one end of the first annular seat 3, and the column 10 is adapted to the second through hole 19. A first through hole 11 is formed through the side wall of the column 10, and the first through hole 11 and the pin 25... 3. When installing the spindle body 1, the water tank 2 and the spindle body 1 are fixed in advance, and the support plate 7 is installed on the horizontal lathe. First, pull the multiple connecting rods 24 so that the multiple circular sliders 22 move along the inner sidewalls of the multiple sleeves 20 until the multiple pins 23 are retracted into the multiple sleeves 20. At this time, the multiple columns 10 are inserted into the multiple second through holes 19. After releasing the multiple connecting rods 24, under the reaction action of the multiple compressed springs 25, the multiple circular sliders 22 are pushed to move in the opposite direction until the multiple pins 23 enter the multiple first through holes 11. At this time, the first annular seat 3 and the second annular seat 4 are in a fixed state, thus completing the installation of the water tank 2. There is no need to install it by tightening bolts and nuts. The operation is simple, saves time, and improves work efficiency.
[0023] Furthermore, the rotating mechanism includes a motor 8, which is fixed to the outer wall of the support plate 7. The output shaft of the support plate 7 is sleeved with a first bevel gear 17, and the outer wall of the sleeve 6 is sleeved with a second bevel gear 18. The second bevel gear 18 and the first bevel gear 17 mesh, driving the motor 8 to rotate the first bevel gear 17. The second bevel gear 18 and the sleeve 6 work together to rotate the U-shaped frame 5. The rotation of the U-shaped frame 5 drives the second annular seat 4 and the first annular seat 3 to rotate, thereby driving the water tank 2 and the main shaft body 1 to rotate, which can perform cutting work.
[0024] Furthermore, the water supply mechanism includes a connecting pipe 15, which is installed through the middle of the other end of the water tank 2. A rotary joint 16 is installed at one end of the connecting pipe 15, and a flexible hose 9 is installed at the other end of the rotary joint 16. One end of the flexible hose 9 is installed inside the sleeve 6. Multiple first circular holes 13 are equally spaced on the outer wall of the other end of the spindle body 1, and all of the multiple first circular holes 13 are connected to the storage cavity 12, connecting the flexible hose 9 to the external water source. Cold water is supplied to the water tank 2 through the flexible hose 9 and the connecting pipe 15, and enters the storage cavity 12 through two second circular holes 14 to cool the spindle body 1. At the same time, the cold water is sprayed onto the cutting blade through the multiple first circular holes 13 to cool the cutting blade. In this way, the cold water inside the storage cavity 12 is always in a state of circulation, which can quickly and effectively remove the generated heat, keeping the surface temperature of the water tank 2 at a low temperature, improving the cooling effect, thereby enhancing the performance and stability of the spindle body 1 and extending the service life of the spindle body 1.
[0025] Working Principle: During operation, the water tank 2 and the main spindle body 1 are pre-fixed. When installing the main spindle body 1, the support plate 7 is first installed on the horizontal lathe. Multiple connecting rods 24 are pulled, causing multiple circular sliders 22 to move along the inner walls of multiple sleeves 20 until multiple pins 23 retract into the sleeves 20. At this point, multiple columns 10 are inserted into multiple second through holes 19. After releasing the connecting rods 24, the multiple circular sliders 22 are pushed in the opposite direction by the reaction force of multiple compressed springs 25 until multiple pins 23 enter the first through holes 11. At this point, the first annular seat 3 and the second annular seat 4 are fixed, thus completing the installation of the water tank 2. Installation is not achieved through bolt and nut tightening, simplifying operation, saving time, and improving work efficiency. During operation, the cutting blade is installed at one end of the main spindle body 1, and the power to the motor 8 is connected. The switch drives the motor 8 to rotate the first bevel gear 17, which in turn rotates the second bevel gear 18 and the sleeve 6 to rotate the U-shaped frame 5. The rotation of the U-shaped frame 5 rotates the second annular seat 4 and the first annular seat 3, which in turn rotates the water tank 2 and the spindle body 1, enabling cutting operations. During operation, the hose 9 is connected to an external water source, and cold water is supplied to the water tank 2 through the hose 9 and the connecting pipe 15. The cold water then enters the storage cavity 12 through the two second round holes 14 to cool the spindle body 1. At the same time, the cold water is sprayed onto the cutting blades through multiple first round holes 13 to cool the cutting blades. In this way, the cold water inside the storage cavity 12 is always in a state of circulation, which can quickly and effectively remove the generated heat, keeping the surface temperature of the water tank 2 at a low temperature, improving the cooling effect, thereby enhancing the performance and stability of the spindle body 1 and extending the service life of the spindle body 1.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
