Description

Technical Field

[0001] The present invention relates to the field of boring, and specifically to a boring device for a motor base. Background Art

[0002] As a key component for connecting the motor and the equipment, the design and manufacture of the motor base directly affect the operation stability, reliability, and service life of the equipment. The motor base provides a firm and reliable support for the motor, ensuring that the motor maintains a stable position during operation and avoiding displacement due to vibration. At the same time, some motor bases are designed with heat dissipation holes or fins, which helps to dissipate heat from the motor and extend the service life of the motor. To meet these requirements, advanced manufacturing processes are essential, such as the use of high-speed boring, grinding, and other machining technologies, combined with strict quality inspections.

[0003] As an important common basic technology in the assembly manufacturing industry, high-speed boring has been widely used in industries such as aerospace, automotive, and mold due to its advantages of improving productivity and machining accuracy, reducing boring force and energy consumption, simplifying the process flow, and shortening the production cycle. However, currently, during the boring process of the boring tool on the market, due to the too high rotational speed of the tool itself and the large impact force it receives after contacting the workpiece during the boring process of the workpiece, the tool is extremely prone to tremor during work, which affects the machining quality of the workpiece surface. More seriously, during the boring process of the tool, it will exacerbate the wear of the tool itself, resulting in fracture and damage of the tool during machining, thus affecting the service life of the tool. Summary of the Invention

[0004] To overcome the deficiency of easy tool tremor during the boring process in the prior art, the present invention provides a boring device for a motor base, which reduces the occurrence of tremor during boring by setting a damping and shock-absorbing component.

[0005] The present invention adopts the following technical solutions.

[0006] A boring device for a motor base includes a base, and a clamping mechanism, a boring mechanism, and a boring moving mechanism arranged on the base. The boring moving mechanism is arranged on the upper surface of the base, the boring mechanism is arranged on the boring moving mechanism, and the boring moving mechanism is used to drive the boring mechanism to move linearly.

[0007] The boring mechanism includes a damping and shock-absorbing component and a boring motor.

[0008] The damping and shock-absorbing assembly includes a tool holder. A boring bar is rotatably arranged in the tool holder. The boring bar is fixedly connected to the boring motor. A cooling cavity and a cooling flow channel are further arranged in the tool holder. The cooling cavity is filled with a coolant. The cooling cavity is rotatably connected to the boring bar and the boring bar is fixedly connected with a first impeller. When the boring motor drives the boring bar to rotate, the first impeller causes the coolant in the cooling cavity to flow into the cooling flow channel.

[0009] A coolant outlet is arranged at the lower end of the boring bar. The coolant outlet is communicated with the cooling flow channel.

[0010] The damping and shock-absorbing assembly further includes a shock-absorbing sleeve rotatably sleeved on the boring bar. The shock-absorbing sleeve is filled with a damping liquid. A second impeller is arranged on the outer side wall of the shock-absorbing sleeve.

[0011] When the coolant flows downward along the cooling flow channel, it will squeeze the second impeller, so that the second impeller drives the shock-absorbing sleeve to rotate around its own axis.

[0012] Preferably, a pressing ring is sleeved on the upper end of the shock-absorbing sleeve. An elastic sealing ring is arranged between the pressing ring and the shock-absorbing sleeve.

[0013] When the coolant flows downward along the cooling flow channel, it generates a downward pressure on the pressing ring, so that the pressing ring moves towards the shock-absorbing sleeve, thereby increasing the pressure of the damping liquid in the shock-absorbing sleeve.

[0014] Preferably, stirring blades for stirring the damping liquid are arranged on the inner wall of the shock-absorbing sleeve.

[0015] Preferably, the boring moving mechanism includes an X-axis moving component and a Z-axis moving component. The X-axis moving component includes a bearing platform and an X-axis displacement screw module. The Z-axis moving component is fixedly installed on the bearing platform. The Z-axis moving component includes a connecting platform and a Z-axis displacement screw module.

[0016] The boring mechanism is fixedly installed on the connecting platform. Driven by the boring moving mechanism, the boring mechanism moves linearly along the X-axis and the Z-axis.

[0017] Preferably, the clamping mechanism includes a clamping platform slidably arranged on the base. Fixed cylinders are symmetrically arranged on the upper end face of the clamping platform. A Y-axis moving component is arranged on the lower end face of the clamping platform.

[0018] Preferably, a dust cover is rotatably arranged on the base. The dust cover is used to prevent dust from overflowing when the boring mechanism is working.

[0019] Preferably, a coolant pump is also fixed to the base, a liquid storage tank is arranged below the base, and the coolant pump conveys the coolant in the liquid storage tank to the cooling cavity.

[0020] The beneficial effects of the present invention are as follows:

[0021] The present invention provides a boring device for a motor base. The boring moving mechanism drives the boring mechanism to move linearly, ensuring the stability and precision of the boring process and improving the machining quality. Moreover, with the introduction of the damping shock-absorbing component, the vibration and impact during the boring process are effectively absorbed, improving the stability of the equipment and extending the service life of the equipment. Finally, the boring motor provides power for the boring mechanism to achieve precise boring of the motor base. Description of the Drawings

The accompanying drawings are only for illustrative purposes and cannot be construed as a limitation of this patent; in order to better illustrate this embodiment, some components in the accompanying drawings will be omitted, enlarged, or reduced, and do not represent the size of the actual product.

[0028] For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. The accompanying drawings are only for illustrative purposes and cannot be construed as a limitation of this patent.

[0029] As shown in the attached Figure 1 - Figure 2 An electric motor base boring device includes a base 1, 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, the boring mechanism is arranged on the boring moving mechanism, and the boring moving mechanism is used to drive the boring mechanism to move linearly; the boring mechanism includes a damping and shock-absorbing component 2 and a boring motor 11.

[0030] By arranging the clamping mechanism, the boring mechanism, and the boring moving mechanism on the base 1, precise boring of the electric motor base can be achieved. The damping and shock-absorbing component 2 and the boring motor 11 can effectively reduce vibration and improve the stability and precision of the boring process.

[0031] The damping and shock-absorbing component 2 includes a tool holder 21. A boring tool bar 22 is rotatably arranged in the tool holder 21. The boring tool bar 22 is fixedly connected to the boring motor 11. A cooling cavity 23 and a cooling flow channel 24 are also arranged in the tool holder 21. The cooling cavity 23 is filled with coolant. The cooling cavity 23 is rotationally connected to the boring tool bar 22 and the boring tool bar 22 is fixedly connected with a first impeller 221. When the boring motor 11 drives the boring tool bar 22 to rotate, the first impeller 221 causes the coolant in the cooling cavity 23 to flow into the cooling flow channel 24. A coolant outlet 222 is arranged at the lower end of the boring tool bar 22. The coolant outlet 222 is communicated with the cooling flow 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 being processed.

[0032] By arranging a cooling cavity 23 and a cooling flow channel 24 inside the cutter barrel 21 and filling it with a coolant, the boring bar 22 can be effectively cooled, preventing overheating, improving the boring efficiency and the tool life. At the same time, the rotation of the first impeller 221 drives the flow of the coolant, 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 boring bar 22 not only increases the boring load but also synchronously drives the first impeller 221 to rotate faster, thereby achieving a synchronous increase in the coolant flow rate. In this way, it can ensure that sufficient cooling is always provided to the boring part of the tool during high-speed and high-load boring, avoiding problems such as reduced machining accuracy and poor surface quality caused by local overheating.

[0033] In some embodiments, the damping and shock-absorbing assembly 2 further includes a shock-absorbing sleeve 25 rotatably sleeved on the boring bar 22. The shock-absorbing sleeve 25 is filled with a damping fluid, and a second impeller 251 is arranged on the outer side wall of the shock-absorbing sleeve 25.

[0034] When the coolant flows downward along the cooling flow channel 24, it will squeeze the second impeller 251, causing the second impeller 251 to drive the shock-absorbing sleeve 25 to rotate around its own axis.

[0035] By arranging a shock-absorbing sleeve 25 on the boring bar 22 and filling the shock-absorbing sleeve 25 with a damping fluid, the damping fluid absorbs vibration energy through internal friction. When the shock-absorbing sleeve 25 or other components vibrate, the damping fluid 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, effectively reducing the vibration generated during boring, and improving the stability and accuracy of boring. The viscosity of the damping fluid determines its damping effect. In this embodiment, a high-viscosity damping fluid is used, and the high-viscosity damping fluid can provide a greater damping force to slow down the amplitude and frequency of vibration. By adjusting the viscosity of the damping fluid, the performance of the shock-absorbing system can be controlled.

[0036] In some embodiments, a pressing ring 252 is sleeved on the upper end of the shock-absorbing sleeve 25, and an elastic sealing ring 253 is arranged between the pressing ring 252 and the shock-absorbing sleeve 25.

[0037] When the coolant flows downward along the cooling channel 24, it generates a downward pressure on the extrusion ring 252, causing the extrusion ring 252 to move towards the shock absorption sleeve 25, thereby increasing the pressure of the damping fluid in the shock absorption sleeve 25. The movement of the extrusion ring 252 increases the pressure of the damping fluid in the shock absorption sleeve 25, and the increased pressure causes the damping fluid to form a stronger damping effect within the shock absorption sleeve 25. This strong damping effect can rapidly attenuate the amplitude and frequency of vibrations, reduce the impact of vibrations on the system, and thus improve the stability and accuracy of the boring process. At the same time, the increased pressure causes the damping fluid in the shock absorption sleeve 25 to fill more tightly between the inner wall of the shock absorption sleeve 25 and the boring tool rod 22, enhancing the rigidity of the system. This enhanced rigidity can more effectively resist vibrations and reduce the possibility of vibrations being transmitted to the boring tool and the workpiece.

[0038] In some embodiments, stirring blades 254 for stirring the damping fluid are provided on the inner wall of the shock absorption sleeve 25. The damping fluid that has been stationary for a long time may stratify due to gravity, resulting in a decline in performance. The stirring blades 254 prevent stratification by continuously agitating the damping fluid, ensuring that the damping fluid always maintains uniform performance. And the stirring blades 254 are provided on the inner wall of the shock absorption sleeve 25. When the shock absorption sleeve 25 rotates, the stirring blades 254 will agitate the damping fluid, increasing the complexity of its flow. This complex flow pattern can more effectively absorb and dissipate vibration energy. Further, during the working process, the vibration energy is 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 blades 254 increase the heat exchange area of the shock absorption sleeve 25, ensuring that the damping fluid is effectively cooled.

[0039] When the coolant flows along the cooling channel 24, it presses against the second impeller 251, causing it to drive the shock absorption sleeve 25 to rotate. As a result, the stirring blades 254 within the shock absorption sleeve 25 cause the damping fluid to rotate within the shock absorption sleeve 25, generating internal frictional force and reducing the transmission of vibrations. Further, the rotation directions of the first impeller 221 and the second impeller 251 are opposite, so that the rotation direction of the damping fluid within the shock absorption sleeve 25 is opposite to the rotation direction of the boring tool rod 22. As a result, a greater relative velocity is generated between the two, and this relative velocity increases the internal frictional force of the damping fluid, thereby absorbing more vibration energy. Moreover, the opposite-direction flow causes the damping fluid to generate a more complex flow path and turbulence within the shock absorption sleeve 25. This complex flow pattern can more effectively dissipate vibration energy, convert it into heat energy and dissipate it, and reduce the transmission of vibrations.

[0040] In some embodiments, the boring movement mechanism includes an X-axis movement component and a Z-axis movement component; the X-axis movement component includes a bearing table 31 and an X-axis displacement lead screw module 51, the Z-axis movement component is fixedly installed on the bearing table 31, and the Z-axis movement component includes a connecting table 41 and a Z-axis displacement lead screw module 52; the boring mechanism is fixedly installed on the connecting table 41, and driven by the boring movement mechanism, the boring mechanism moves linearly along the X-axis and the Z-axis.

[0041] Through the design of the X-axis movement component and the Z-axis movement component, the boring mechanism can move precisely in two directions, thus realizing complex boring operations and improving the machining accuracy. The multi-axis movement component can quickly adjust the boring position, reduce the machining time, and improve the overall machining efficiency. The independent movement of the X-axis and the Z-axis enables the boring mechanism to adapt to different machining requirements, enhancing the flexibility and adaptability of the equipment.

[0042] In some embodiments, the clamping mechanism includes a clamping table 6 slidably arranged on the base 1. Symmetrically arranged fixing cylinders 61 are provided on the upper end surface of the clamping table 6, and a Y-axis movement component 62 is provided on the lower end surface of the clamping table 6. The fixing cylinders 61 clamp the workpiece by pneumatic means. The design of the fixing cylinders 61 ensures that the workpiece remains stable during the boring process, avoiding machining errors caused by workpiece movement. The Y-axis movement component 62 can drive the clamping table 6 to move along the Y-axis. Through the X-axis movement component, the Y-axis movement component 62 and the Z-axis movement component, three-axis machining of the workpiece can be performed to meet the requirements of different boring positions.

[0043] In some embodiments, a dust-proof cover 7 is also rotatably arranged on the base 1. The dust-proof cover 7 is used to prevent dust from overflowing when the boring component is working. The dust-proof cover 7 covers the boring area during the boring process to prevent the dust and debris generated by boring from overflowing, keeping the working environment clean. The dust-proof cover 7 can effectively isolate the dust and debris generated during the boring process, reduce the health hazards to the operator, and improve the work safety.

[0044] In some embodiments, a coolant pump 8 is also fixed on the base 1. A liquid storage tank is arranged below the base 1. The coolant pump 8 conveys the coolant in the liquid storage tank to the cooling cavity 23. Through the design of the coolant pump 8 and the liquid storage tank, continuous and effective cooling during the boring process is ensured to prevent overheating. The coolant pump 8 can convey the coolant in the liquid storage tank to the cooling cavity 23 to ensure that the coolant is always in a flowing state during the boring process, improving the cooling efficiency. An effective cooling system can reduce the heat generated during the boring process, prevent the equipment and tools from overheating, and thus extend their service life.

For those of ordinary skill 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 enumerate all the implementation manners here.
