A vibration damping device is provided on the lower surface of the spindle body. The vibration damping device includes a damping plate, which is slidably connected to the lower surface of the spindle body. Four first springs are fixedly connected to the lower surface of the damping plate, and a base plate is fixedly connected to one end of each of the four first springs. Two connecting plates are fixedly connected to the surface of the base plate, and both connecting plates are in contact with the surface of the spindle body. This vibration-damping, air-cooled woodworking electric spindle avoids the vibration generated during high-speed rotation of the spindle body and woodworking processing from directly acting on the spindle body and connected external equipment.

Description

Technical Field

[0001] This utility model relates to the technical field of power components for woodworking machinery, and in particular to a vibration-damping, air-cooled electric spindle for woodworking. Background Technology

[0002] As the core power source of woodworking equipment, the performance of the electric spindle directly determines the processing efficiency, workpiece quality, and equipment lifespan. Currently, woodworking electric spindles on the market generally suffer from the following technical pain points: Traditional electric spindles mostly rely on a single bearing for vibration damping. During high-speed operation, rotor imbalance and vibrations generated by cutting forces are easily transmitted to the spindle body and external equipment. This not only leads to burrs and dimensional deviations on the workpiece surface but also accelerates the wear of bearings, stators, and other components, shortening the electric spindle's lifespan. Simultaneously, the generated high-frequency noise degrades the working environment.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: the vibration generated during the high-speed operation of the spindle body and woodworking will directly act on the spindle body and the connected external equipment. The vibration will cause the internal components of the spindle body (such as bearings, stator, rotor, etc.) to be subjected to additional impact forces, resulting in wear, loosening or even damage of the components, which will cause the service life of the spindle body to be greatly shortened. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of avoiding the vibration generated during the high-speed operation of the spindle body and woodworking, which will directly act on the spindle body and the connected external equipment. The vibration will cause the internal components of the spindle body (such as bearings, stator, rotor, etc.) to be subjected to additional impact force, resulting in wear, loosening or even damage of the components. To this end, we propose a vibration-damping air-cooled woodworking electric spindle.

[0005] To achieve the above objectives, this application adopts the following technical solution: a vibration-damping, air-cooled woodworking electric spindle, comprising a spindle body, a vibration damping device provided on the lower surface of the spindle body, the vibration damping device comprising a vibration damping plate, the vibration damping plate being slidably connected to the lower surface of the spindle body, four first springs being fixedly connected to the lower surface of the vibration damping plate, one end of the four first springs being fixedly connected to a base plate, and two connecting plates being fixedly connected to the surface of the base plate, both of the connecting plates being in contact with the surface of the spindle body.

[0006] Preferably, two arc-shaped plates are fixedly connected to one side of the main shaft body, and a slide rod is slidably inserted in the arc-shaped plate. One end of the slide rod is fixedly connected to an inclined plate, and the surfaces of the two inclined plates are slidably connected to the shock-absorbing plate.

[0007] Preferably, a second spring is fitted onto the arc surface of the slide rod, and the two ends of the second spring are fixedly connected to the arc plate and the slide rod, respectively.

[0008] Preferably, a shock-absorbing pad is fixedly connected to the surface of the connecting plate, and the surface of the shock-absorbing pad is in contact with the main shaft body.

[0009] Preferably, a heat dissipation device is provided on one side of the spindle body. The heat dissipation device includes a fixing frame, which is fixedly connected to the surface of the spindle body. A filter screen is slidably connected to the inner surface of the fixing frame. Two round rods are fixedly connected to the surface of the fixing frame. A shaped plate is rotatably connected to the arc surface of the round rods. The surface of the shaped plate is slidably connected to the filter screen. Two baffle plates are fixedly connected to one side of the filter screen.

[0010] Preferably, a torsion spring is fitted onto the arc surface of the round rod, and the two ends of the torsion spring are fixedly connected to the round rod and the irregular plate, respectively.

[0011] Preferably, the surface of the fixing frame has two square grooves, and a square rod is slidably connected to the surface of the square grooves of the fixing frame.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by setting a shock-absorbing device, the effect of reducing the vibration of the spindle body during use is achieved. This avoids the vibration generated during high-speed operation of the spindle body and woodworking processing from directly acting on the spindle body and connected external equipment. Vibration would cause the internal components of the spindle body (such as bearings, stator, rotor, etc.) to be subjected to additional impact forces, resulting in wear, loosening or even damage of the components, which would significantly shorten the service life of the spindle body. This improves the practicality of the device.

[0014] In this invention, by setting up a heat dissipation device, the temperature inside the spindle body is reduced, which prevents the heat generated by the high-speed operation of the spindle body from accumulating inside the spindle body and causing the internal temperature to rise continuously. High temperature will accelerate the aging and carbonization of the insulation layer of the motor stator winding, and may even cause a short circuit and burn out the motor, resulting in the spindle body malfunctioning and stopping. This improves the practicality of the device. Attached Figure Description

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0024] Reference Figure 1 As shown, this utility model provides a technical solution: a vibration-damping, air-cooled woodworking electric spindle, including a spindle body 1. A vibration damping device 2 is provided on the lower surface of the spindle body 1. By setting the vibration damping device 2, the effect of vibration on the spindle body 1 during use is reduced, avoiding the vibration generated during high-speed operation of the spindle body 1 and woodworking processing from directly acting on the spindle body 1 and connected external equipment. Vibration will cause the internal components of the spindle body 1 (such as bearings, stator, rotor, etc.) to be subjected to additional impact force, resulting in wear, loosening or even damage of the components, which will significantly shorten the service life of the spindle body 1. This improves the practicality of the device. A heat dissipation device 3 is provided on one side of the spindle body 1. By setting the heat dissipation device 3, the effect of reducing the internal temperature of the spindle body 1 is achieved, avoiding the heat generated by the high-speed operation of the spindle body 1 from accumulating inside the spindle body 1, which will cause the internal temperature to rise continuously. High temperature will accelerate the aging and carbonization of the insulation layer of the motor stator winding, and may even cause a short circuit and burn out the motor, causing the spindle body 1 to malfunction and stop operating. This improves the practicality of the device.

[0025] The following section will explain the specific setup and function of its shock absorption device 2 and heat dissipation device 3.

[0026] Reference Figure 2 and Figure 3 As shown in this embodiment: the shock absorption device 2 includes a shock absorption plate 21, which is slidably connected to the lower surface of the main shaft body 1. Four first springs 22 are fixedly connected to the lower surface of the shock absorption plate 21. One end of each of the four first springs 22 is fixedly connected to a base plate 23. Two connecting plates 24 are fixedly connected to the surface of the base plate 23. Both connecting plates 24 are in contact with the surface of the main shaft body 1. Two arc-shaped plates 25 are fixedly connected to one side of the main shaft body 1. A slide rod 26 is slidably inserted into the arc-shaped plate 25. One end of each slide rod 26 is fixedly connected to an inclined plate 27. The surfaces of both inclined plates 27 are slidably connected to the shock absorption plate 21, which facilitates the placement of the shock absorption plate 21 by the operator and provides good guidance and limiting for the placement of the shock absorption plate 21, making it convenient for the operator to quickly place the shock absorption plate 21. The device simplifies the installation process and improves efficiency by quickly and accurately placing the damping plate 21 in the appropriate position. The arc surface of the slide rod 26 is fitted with a second spring 28, and the two ends of the second spring 28 are fixedly connected to the arc plate 25 and the slide rod 26 respectively, achieving the effect of automatically bringing the inclined plate 27 back. After the operator completes the placement of the damping plate 21, the inclined plate 27 is automatically brought back to the initial position without manual reset, improving the convenience of operation. The surface of the connecting plate 24 is fixedly connected with a damping pad 29, and the surface of the damping pad 29 is in contact with the spindle body 1, which reduces the collision between the spindle body 1 and the connecting plate 24, further weakens the vibration transmission, and helps to improve the overall vibration reduction effect of the spindle body 1, indirectly ensuring the stability of the woodworking processing accuracy.

[0027] Reference Figure 4 , Figure 5 and Figure 6As shown, specifically, the heat dissipation device 3 includes a fixing frame 31, which is fixedly connected to the surface of the spindle body 1. A filter screen 32 is slidably connected to the inner surface of the fixing frame 31. Two round rods 33 are fixedly connected to the surface of the fixing frame 31. A shaped plate 34 is rotatably connected to the arc surface of the round rods 33. The surface of the shaped plate 34 is slidably connected to the filter screen 32. Two baffle plates 35 are fixedly connected to one side of the filter screen 32. A torsion spring 37 is sleeved on the arc surface of the round rods 33. The two ends of the torsion spring 37 are fixedly connected to the round rods 33 and the shaped plate 34 respectively, achieving the effect of maintaining the stability of the shaped plate 34 and preventing damage to the spindle body. The vibration of the main body 1 causes the irregular plate 34 to loosen and shift, thereby ensuring that the filter screen 32 is firmly installed in the fixing frame 31, so as to always play the role of intercepting dust and ensuring the cleanliness of the heat dissipation air duct. Two square grooves are opened on the surface of the fixing frame 31, and square rods 36 are slidably connected to the surface of the square grooves of the fixing frame 31, which achieves the effect of limiting the position of the irregular plate 34. This prevents the irregular plate 34 from being affected by external forces when the filter screen 32 is installed, which would cause the irregular plate 34 to rotate to a certain extent, so that the moved irregular plate 34 would rub against the filter screen 32 and cause damage to the irregular plate 34.

[0028] Working principle: The base plate 23 is fixedly connected to external objects (such as a workbench). When the operator needs to install the shock absorber 21, the operator first pushes the main spindle body 1 to move the arc plate 25. The arc plate 25 moves the slide rod 26, which in turn moves the inclined plate 27 until the surface of the inclined plate 27 is in contact with the shock absorber 21. At this point, the operator can push the main spindle body 1, and the surface of the inclined plate 27 slides against the shock absorber 21. At this time, the second spring 28 is stretched until the position of the shock absorber 21 no longer affects the movement of the inclined plate 27. The rebound force of the second spring 28 then moves the inclined plate... Move 27 until the surface of the inclined plate 27 slides against the damping plate 21. At this time, the surface of the spindle body 1 is completely in contact with the damping pad 29, which reduces the impact of vibration on the spindle body 1 during use. This avoids the vibration generated during high-speed operation of the spindle body 1 and woodworking processing from directly acting on the spindle body 1 and the connected external equipment. Vibration will cause the internal components of the spindle body 1 (such as bearings, stator, rotor, etc.) to be subjected to additional impact force, wear, loosening or even damage of the components, resulting in a significant reduction in the service life of the spindle body 1, thus improving the practicality of the device.

[0029] When the staff needs to disassemble the filter screen 32 for cleaning, firstly, the staff rotates the irregular plate 34 on the arc surface of the round rod 33 until the surface of the irregular plate 34 is in contact with the square rod 36. At this time, the position of the irregular plate 34 does not affect the movement of the filter screen 32. Then, the staff pushes the square rod 36 to slide on the surface of the irregular plate 34 until the surface of the square rod 36 is completely in contact with the irregular plate 34. At this time, the staff can pull the filter screen 32 to slide within the fixing frame 31 until the surface of the filter screen 32 is completely separated from the fixing frame 31. Then, the staff can clean the filter screen 32. After cleaning, the staff puts the filter screen back in place. The worker pushes the square rod 36 to slide on the surface of the square groove of the fixed frame 31 until the position of the square rod 36 does not affect the movement of the irregular plate 34. Then the torque of the torsion spring 37 drives the irregular plate 34 to move until the surface of the irregular plate 34 is in contact with the baffle plate 35. At this time, the temperature inside the spindle body 1 is reduced, which prevents the heat generated by the high-speed operation of the spindle body 1 from accumulating inside the spindle body 1, causing the internal temperature to rise continuously. High temperature will accelerate the aging and carbonization of the insulation layer of the motor stator winding, and even cause a short circuit and burn out the motor, resulting in the spindle body 1 malfunctioning and stopping. This improves the practicality of the device.

Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
