The drawings are only used for exemplary illustration and cannot be understood as limitations on this patent; in order to better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0018] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The drawings are only used for exemplary description and cannot be understood as limiting the present patent.

[0019] As attached Figure 1-Figure 2 A motor base boring device is shown, which includes a base 1, and a clamping mechanism, a boring mechanism and a boring moving mechanism arranged on the base 1. The boring moving mechanism is arranged on the upper surface of the base 1, and the boring mechanism is arranged on the boring moving mechanism. The boring moving mechanism is used to drive the boring mechanism to move linearly; the boring mechanism includes a damping and shock absorbing assembly 2 and a boring motor 11.

[0020] The motor base can be accurately bored by the clamping mechanism, boring mechanism and boring moving mechanism arranged on the base 1. The damping and shock absorbing assembly 2 and the boring motor 11 can effectively reduce vibration and improve the stability and accuracy of the boring process.

[0021] In some embodiments, the damping and shock absorbing assembly 2 includes a cutter barrel 21, a milling cutter rod 22 is rotatably arranged in the cutter barrel 21, the milling cutter rod 22 is fixedly connected to the boring motor 11, a cooling chamber 23 and a cooling channel 24 are also arranged in the cutter barrel 21, the cooling chamber 23 is filled with coolant, a first impeller 221 fixedly connected to the milling cutter rod 22 is arranged in the cooling chamber 23, when the boring motor 11 drives the milling cutter rod 22 to rotate, the first impeller 221 makes the coolant in the cooling chamber 23 flow to the cooling channel 24, and a coolant outlet 222 is arranged at the lower end of the milling cutter rod 22, and the coolant outlet 222 is connected to the cooling channel 24. During the boring process, the coolant flows out from the coolant outlet 222, and the coolant will cool the milling cutter head and the workpiece.

[0022] By arranging a cooling chamber 23 and a cooling channel 24 in the cutter barrel 21 and filling it with coolant, the milling cutter rod 22 can be effectively cooled to prevent overheating, thereby improving boring efficiency and tool life. At the same time, the rotation of the first impeller 221 drives the coolant to flow, further stabilizing the boring process. Through the rotation of the first impeller 221, a strong hydraulic pressure is formed to drive the coolant to circulate at a higher flow rate. This active cooling method is closely coupled with the boring process. The increase in the rotation speed of the milling cutter rod 22 not only increases the boring load, but also synchronously drives the first impeller 221 to accelerate the rotation, thereby achieving a synchronous increase in the coolant flow rate. In this way, it can be ensured that during high-speed and high-load boring processing, sufficient cooling is always provided for the boring part of the tool to avoid problems such as reduced processing accuracy and poor surface quality due to local overheating.

[0023] In some embodiments, the damping shock absorbing assembly 2 further includes a shock absorbing sleeve 25 rotatably mounted on the milling cutter rod 22 , the shock absorbing sleeve 25 is filled with damping fluid, and a second impeller 251 is disposed on the outer side wall of the shock absorbing sleeve 25 .

[0024] When the coolant flows from top to bottom along the cooling channel 24 , it squeezes the second impeller 251 , so that the second impeller 251 drives the damping sleeve 25 to rotate around its own axis.

[0025] By arranging a shock-absorbing sleeve 25 on the milling cutter rod 22 and filling the shock-absorbing sleeve 25 with a damping liquid, the damping liquid absorbs vibration energy through internal friction. When the shock-absorbing sleeve 25 or other components are vibrating, the damping liquid will generate internal flow, and this flow will generate friction, thereby converting the vibration energy into heat energy and dissipating it, reducing the transmission of vibration, and can effectively reduce the vibration generated during the boring process, and improve the stability and accuracy of boring. The viscosity of the damping liquid determines its damping effect. In this embodiment, a high-viscosity damping liquid is used. The high-viscosity damping liquid can provide a greater damping force and reduce the amplitude and frequency of vibration. By adjusting the viscosity of the damping liquid, the performance of the shock-absorbing system can be controlled.

[0026] In some embodiments, an extrusion ring 252 is sleeved on the upper end of the shock-absorbing sleeve 25 , and an elastic sealing ring 253 is provided between the extrusion ring 252 and the shock-absorbing sleeve 25 .

[0027] When the coolant flows from top to bottom along the cooling channel 24, downward pressure is generated on the extrusion ring 252, causing the extrusion ring 252 to move toward the direction close to the shock-absorbing sleeve 25, thereby increasing the pressure of the damping liquid in the shock-absorbing sleeve 25. The movement of the extrusion ring 252 increases the pressure of the damping liquid in the shock-absorbing sleeve 25, and the increased pressure causes the damping liquid to form a stronger damping effect in the shock-absorbing sleeve 25. This strong damping effect can quickly attenuate the amplitude and frequency of vibration, reduce the impact of vibration on the system, and thus improve the stability and accuracy of the boring process. At the same time, the increase in pressure can cause the damping liquid in the shock-absorbing sleeve 25 to be more tightly filled between the inner wall of the shock-absorbing sleeve 25 and the milling cutter rod 22, thereby enhancing the rigidity of the system. This enhanced rigidity can more effectively resist vibration and reduce the possibility of vibration being transmitted to the boring tool and the workpiece.

[0028] In some embodiments, the inner wall of the shock-absorbing sleeve 25 is provided with a stirring blade 254 for stirring the damping fluid. The damping fluid that is static for a long time may be stratified due to the effect of gravity, resulting in performance degradation. The stirring blade 254 prevents the damping fluid from being stratified by constantly stirring the damping fluid, thereby ensuring that the damping fluid always maintains uniform performance. In addition, the stirring blade 254 is arranged on the inner wall of the shock-absorbing sleeve 25. When the shock-absorbing sleeve 25 rotates, the stirring blade 254 stirs the damping fluid, increasing the complexity of its flow. This complex flow pattern can more effectively absorb and dissipate vibration energy. Furthermore, during the working process, the vibration capacity will be converted into the internal energy of the damping fluid, causing the temperature of the damping fluid to rise. The second impeller 251 and the stirring blade 254 increase the heat exchange area of ​​the shock-absorbing sleeve 25, ensuring that the damping fluid is effectively cooled.

[0029] When the coolant flows along the cooling channel 24, it squeezes the second impeller 251, causing it to drive the shock-absorbing sleeve 25 to rotate, so that the stirring blades 254 in the shock-absorbing sleeve 25 cause the damping liquid to rotate in the shock-absorbing sleeve 25, generating internal friction and reducing the transmission of vibration. Furthermore, the first impeller 221 rotates in opposite directions to the second impeller 251, so that the rotation direction of the damping liquid in the shock-absorbing sleeve 25 is opposite to the rotation direction of the milling cutter rod 22, and a greater relative speed is generated between the two. This relative speed increases the friction inside the damping liquid, thereby absorbing more vibration energy. In addition, the flow in opposite directions will cause the damping liquid to generate a more complex flow path and turbulence in the shock-absorbing sleeve 25. This complex flow pattern can more effectively dissipate vibration energy, convert it into heat energy and dissipate it, reducing the transmission of vibration.

[0030] In some embodiments, the boring moving mechanism includes an X-axis moving component and a Z-axis moving component; the X-axis moving component includes a carrier table 31 and a linear displacement screw module 5, the Z-axis moving component is fixedly mounted on the carrier table 31, and the Z-axis moving component includes a connecting table 41 and a linear displacement screw module 5; the boring mechanism is fixedly mounted on the connecting table 41, and is driven by the boring moving mechanism to move linearly along the X-axis and the Z-axis.

[0031] Through the design of X-axis moving components and Z-axis moving components, the boring mechanism can move precisely in two directions, thereby realizing complex boring operations and improving processing accuracy. The multi-axis moving component can quickly adjust the boring position, reduce processing time, and improve overall processing efficiency. The independent movement of the X-axis and Z-axis enables the boring mechanism to adapt to different processing requirements, enhancing the flexibility and adaptability of the equipment.

[0032] In some embodiments, the clamping mechanism includes a clamping table 6 slidably disposed on the base 1, a fixed cylinder 61 is symmetrically disposed on the upper end surface of the clamping table 6, and a Y-axis moving component 62 is disposed on the lower end surface of the clamping table 6. The fixed cylinder 61 clamps the workpiece pneumatically, and the design of the fixed cylinder 61 ensures that the workpiece remains stable during the boring process to avoid processing errors caused by the movement of the workpiece. The Y-axis moving component 62 can drive the clamping table 6 to move along the Y-axis. Through the X-axis moving component, the Y-axis moving component 62 and the Z-axis moving component, the workpiece can be processed in three axes to meet the needs of different boring positions.

[0033] In some embodiments, the base 1 is also rotatably provided with a dust cover 7, which is used to prevent dust from overflowing when the boring assembly is working. The dust cover 7 covers the boring area during the boring process to prevent the dust and debris generated by the boring from overflowing and keep the working environment clean. The dust cover 7 can effectively isolate the dust and debris generated during the boring process, reduce the health hazards to the operator, and improve work safety.

[0034] In some embodiments, the base 1 is also fixed with a coolant pump 8, and a liquid storage tank is arranged below the base 1. The coolant pump 8 delivers the coolant in the liquid storage tank to the cooling chamber 23. The design of the coolant pump 8 and the liquid storage tank ensures continuous and effective cooling during the boring process to prevent overheating. The coolant pump 8 can deliver the coolant in the liquid storage tank to the cooling chamber 23, ensuring that the coolant is always in a flowing state during the boring process, thereby improving the cooling efficiency. An effective cooling system can reduce the heat generated during the boring process, prevent overheating of equipment and tools, and thus extend their service life.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
