Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and in particular to a nano-grinding wheel active shaft support rotation mechanism. Background Technology

[0002] A nano-grinding wheel is a grinding tool that uses nano-sized abrasive particles, typically ranging from 1 to 100 nanometers in diameter. The surface of the nano-grinding wheel is coated with an adhesive, ensuring a strong bond between the abrasive particles, uniform distribution, and stable adhesion strength. The nano-grinding wheel primarily grinds the material surface using these particles, achieving efficient processing and precise control over the fineness of the material. It can smooth the material surface and achieve high-precision processing results. However, existing nano-grinding wheels suffer from damage during the grinding process due to direct contact between the wheel and the material. This damage, if significant, affects the grinding effect. Furthermore, the lack of necessary support mechanisms leads to uneven force distribution during grinding, reducing the wheel's stability and impacting grinding quality. Utility Model Content

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 4 As shown, the present invention discloses a nano-grinding wheel drive shaft support rotation mechanism, including a roller body 1, a support assembly 2 disposed on the roller body 1, and a feeding assembly 3 used in conjunction with the roller body 1. The support assembly 2 includes a base 21 and a rolling bearing 22 disposed on the base 21. The feeding assembly 3 includes a rod 31 and a transmission component 32 disposed on the rod 31. The roller body 1 passes through the rolling bearing 22 and protrudes out of the base 21. The roller body 1 and the rod 31 are spaced apart and arranged parallel to each other. The rod 31 is used to roll and transport external workpieces so that the roller body 1 can grind the surface of the external workpieces.

[0028] During operation, one end of the roller 1 passes through the rolling bearing 22 and protrudes beyond the seat 21. The rolling bearing 22 smoothly supports the rotating roller 1, ensuring its normal operation and rotational accuracy. Furthermore, by converting sliding friction into rolling friction, friction loss is reduced, improving the operating efficiency and reliability of the roller 1. The other end of the roller 1 is connected to an external drive mechanism. The feeding assembly 3 is located below the roller 1, positioned parallel to and spaced from the roller 1 and the rod 31. This allows the rod 31 to roll and transport external workpieces, facilitating fine grinding of the workpiece surface by the roller 1. The rod 31 also provides support and lift to the roller 1 during the smooth transport of the workpiece, ensuring even and balanced force distribution. This invention, through the combined use of the support assembly 2 and the feeding assembly 3, achieves excellent support and lift for the roller 1, improving operational stability and grinding quality.

[0029] In this embodiment, a base 23 is provided below the seat 21. A sliding plate 24 is provided at the bottom of the seat 21, and a slider 25 is provided on the sliding plate 24. The base 23 is provided with a guide rail 26 that is slidably connected to the slider 25. Both ends of the base 23 are provided with stop plates 27, which are used to prevent contact with the slider 25. Specifically, when an external driving mechanism drives the roller 1 to adjust the grinding position, it ensures that the surface of the workpiece is thoroughly ground. Since the seat 21 is connected to the sliding plate 24, and the sliding plate 24 is slidably connected to the guide rail 26 through the slider 25, the position of the seat 21 can be finely adjusted by the sliding connection between the sliding plate 24 and the base 23. This allows the positions of the left and right ends of the roller 1 to be adjusted in a balanced manner. The stop plates 27 at both ends of the base 23 effectively limit the movement of the seat 21 when the stop plates 27 prevent contact with the slider 25, thus ensuring high operational safety.

[0030] In this embodiment, a limiting strip 28 is provided on one side of the sliding plate 24. The inner side of the limiting strip 28 stops it from contacting the outer side of the seat 21. The seat 21 is provided with a mounting hole 29, and the sliding plate 24 is provided with a connecting hole 210. The mounting hole 29 communicates with the connecting hole 210. Specifically, the sliding plate 24 stops the seat 21 from contacting the outer side of the seat 21 by the limiting strip 28, thus better defining the position of the seat 21 on the sliding plate 24. Then, an external screw is used to pass through the mounting hole 29 and connect and fix it to the connecting hole 210, thereby fixing the position of the seat 21 on the sliding plate 24, resulting in good positioning effect.

[0031] In this embodiment, both ends of the rod body 31 are provided with a first mounting end cap 33, a second mounting end cap 34 connected to the first mounting end cap 33, and a mounting screw 35 disposed between the first mounting end cap 33 and the second mounting end cap 34. The mounting screw 35 passes through the first mounting end cap 33 and protrudes out of the second mounting end cap 34. The side of the second mounting end cap 34 away from the first mounting end cap 33 is provided with an annular groove 36. The annular groove 36 is provided with a bearing 37. A fixing cover 38 is provided on the outer side of the second mounting end cap 34. Specifically, the rod body 31 passes through the first mounting end cap 33 and the second mounting end cap 34, and the mounting screw 35 passes through the first mounting end cap 33 and protrudes out of the second mounting end cap 34, thereby better fixing the positions of the first mounting end cap 33 and the second mounting end cap 34 on the rod body 31. Moreover, the second mounting end cap 34 places the bearing component 37 through the annular groove 36, so that the bearing component 37 is sleeved on the outside of the rod body 31. The fixing cover 38 covers the bearing component 37 and connects to the outside of the second mounting end cap 34, thereby fixing the position of the bearing component 37 on the second mounting end cap 34. The structure is compact and reasonably designed, and the connection is stable and reliable.

[0032] In this embodiment, the roller body 1 is provided with a nano-diamond layer 4, which is sleeved on the outside of the roller body 1. The roller body 1 is provided with a first axial groove 11, and multiple first axial grooves 11 are provided. The multiple first axial grooves 11 are arranged in a ring array around the central axis of the roller body 1. The nano-diamond layer 4 is provided with a second axial groove 41, and multiple second axial grooves 41 are provided. The multiple second axial grooves 41 are arranged in a ring array around the central axis of the nano-diamond layer 4. The first axial grooves 11 and the second axial grooves 41 are arranged opposite to each other. Specifically, the nano-diamond layer 4 is fitted onto the outer side of the roller body 1. The nano-diamond layer 4 consists of tiny diamond particles with a diameter typically between 1 and 10 nanometers. Nano-diamonds are ultrafine diamond powders synthesized under high pressure and high temperature conditions, possessing extremely high hardness and corrosion resistance. This enhances the fine grinding effect of the roller body 1 on the workpiece surface. Multiple first axial grooves 11 are arranged in a circular array around the central axis of the roller body 1, and multiple second axial grooves 41 are arranged in a circular array around the central axis of the nano-diamond layer 4. Moreover, the first axial grooves 11 and the second axial grooves 41 are arranged opposite to each other, so that an external key can be inserted between the first axial grooves 11 and the second axial grooves 41 to fix the position of the nano-diamond layer 4 fitted onto the outer side of the roller body 1. A key is a standard part, typically used to connect rotating and oscillating parts on a shaft, serving to circumferentially fix the parts to transmit rotational motion and torque.

[0033] In this embodiment, a connecting cover 5 is provided between the roller body 1 and the nano-diamond layer 4. The connecting cover 5 is provided with an internal thread 51, and the roller body 1 is provided with an external thread 12 that engages with the internal thread 51. Specifically, the connecting cover 5 is connected by the engagement of the internal thread 51 and the external thread 12, which facilitates the detachable connection between the connecting cover 5 and the roller body 1, making installation and disassembly convenient and the connection stable and reliable.
