DETAILED DESCRIPTION

[0039] The utility model is described in detail below in combination with the drawings.

[0040] As Figures 1 to 4 shown, the utility model relates to a kind of active motor mounting mechanism of nano grinding wheel, including motor base 1 and lifting adjustment base 2,

[0041] Motor base 1 is provided with fixed sleeve 11 and at least two fixed seats 12, two fixed seats 12 are connected to the outside of fixed sleeve 11, and fixed seat 12 is connected with lifting adjustment base 2, so that active motor passes through motor base 1 and is fixed to lifting adjustment base 2.

[0042] Lifting adjustment base 2 is provided with guide support foot 21, first buffer support foot 22 and second buffer support foot 23,

[0043] Guide support foot 21 is slidably connected with lifting adjustment base 2, so that lifting adjustment base 2 slides up and down along guide support foot 21.

[0044] First buffer support foot 22 is arranged at the bottom of lifting adjustment base 2 and is used to support lifting adjustment base 2, so that lifting adjustment base 2 is supported and no longer slides downward after sliding downward to a certain height along guide support foot 21;

[0045] The upper portion of second buffer support foot 23 is in contact with lifting adjustment base 2 and is used to limit the amplitude of lifting adjustment base 2 rising, so that lifting adjustment base 2 is limited and no longer slides upward after sliding upward to a certain height along guide support foot 21.

[0046] Through the design of lifting adjustment base 2, the active motor mounting mechanism of nano grinding wheel can be quickly adjusted to adapt to the change of grinding gap. Compared with the traditional belt or chain tensioning adjustment mode, this mechanism does not need to adjust the tensioner, and can easily adapt to the change of grinding gap between grinding wheel and driven wheel by adjusting the height of lifting adjustment base 2, thereby improving the adjustment efficiency.

[0047] In use, the lifting adjusting base 2 is supported and cannot slide downward any more after sliding downward along the guide support leg 21 to a certain height, and the lifting adjusting base 2 is limited and cannot slide upward any more after sliding upward along the guide support leg 21 to a certain height, so that the lifting adjusting base 2 is in a suspended state. When the gap between the grinding wheel and the driven wheel is adjusted, the motor, the motor base 1 and the lifting adjusting base 2 are pulled to slide along the guide support leg 21 by the transmission member, so as to adapt to the change of the grinding gap and ensure that the motor and the nano grinding wheel are in a transmission state.

[0048] As shown in Figure 3 The first buffer support leg 22 is provided with a first buffer 24, and the first buffer 24 is sleeved on the upper part of the first buffer support leg 22 and abuts against the bottom of the lifting adjusting base 2. The lifting adjusting base 2 is supported by the elastic force of the first buffer 24, so that the lifting adjusting base 2 is supported and cannot slide downward any more after sliding downward along the guide support leg 21 to a certain height. When the lifting adjusting base 2 needs to rise, the first buffer 24 can provide power for the lifting adjusting base 2 by the elastic force of its deformation, so that the lifting adjusting base 2 is more easily slid upward, and the operation difficulty and energy consumption are reduced.

[0049] The first buffer 24 is elastic rubber, a spring or a buffer air bag, and in this embodiment, the first buffer 24 is taken as an example of a spring.

[0050] The first buffer support leg 22 is in a column type, the top of the first buffer support leg 22 is provided with a limiting groove, and the first buffer 24 is arranged in the limiting groove. The first buffer 24 is prevented from displacing on the first buffer support leg 22 by the limiting groove, and the stability of the work of the first buffer 24 is confirmed.

[0051] As shown in Figure 3 The second buffer support leg 23 is provided with a second buffer 25, and the second buffer 25 is sleeved on the upper part of the second buffer support leg 23 and abuts against the top of the lifting adjusting base 2. The lifting adjusting base 2 is limited by the second buffer 25 to rise, so that the lifting adjusting base 2 is limited and cannot slide upward any more after sliding upward along the guide support leg 21 to a certain height.

[0052] The second buffer 25 is elastic rubber, a spring or a buffer air bag, and in this embodiment, the second buffer 25 is taken as an example of a spring.

[0053] Specifically, the top of the second buffer support leg 23 is provided with a limiting nut abutting against the second buffer 25. The second buffer 25 is limited on the top of the second buffer support leg 23 by the limiting nut.

[0054] As shown in Figure 2The fixing sleeve 11 is internally provided with a fixing cavity 111, and the driving motor is fixed in the fixing cavity 111.

[0055] The fixing seat 12 and the lifting adjusting base 2 are provided with a heat dissipation gap.

[0056] The fixing sleeve 11 is internally provided with a fixing cavity 111 to accommodate the driving motor. Meanwhile, the driving motor is fixed in the fixing cavity 111, which enhances the stability and safety of the motor.

[0057] The fixing sleeve 11 is externally provided with a junction box 112, which makes the electrical connection more convenient and allows the wiring operation to be performed without disassembling the entire device.

[0058] The heat dissipation gap between the fixing seat 12 and the lifting adjusting base 2 helps to improve the heat dissipation condition of the motor. When the driving motor is working, the heat generated can be quickly dissipated through the heat dissipation gap, avoiding the performance decline or damage caused by overheating of the motor. The service life of the motor is prolonged, and the reliability of the entire device is improved.

[0059] As shown in the drawings, Figure 2 The fixing seat 12 of the embodiment includes a bent portion 121 and a straight portion 122, and the bent portion 121 and the straight portion 122 are integrally formed. The fixing seat 12 adopts the design of integrally forming the bent portion 121 and the straight portion 122, which not only simplifies the manufacturing process, but also significantly improves the overall structural strength.

[0060] The bent portion 121 is connected with the fixing sleeve 11, and the straight portion 122 is connected with the lifting adjusting base 2. The fixing sleeve 11 is connected with the lifting adjusting base 2 through the fixing seat 12, which makes the connection between the fixing sleeve 11 and the lifting adjusting base 2 more stable.

[0061] As shown in the drawings, Figure 4 The embodiment further includes a driving transmission seat 3,

[0062] The driving transmission seat 3 is provided with a driving seat 31, a bearing 32, and a shaft cover 33,

[0063] Both ends of the driving seat 31 are provided with a containing groove (311) for containing the bearing 32, the bearing 32 is arranged in the containing groove (311), and the shaft cover 33 is installed outside the containing groove (311) and limits the bearing 32;

[0064] The nanometer grinding wheel is connected with the bearing 32 through the shaft cover 33.

[0065] The design of the driving seat 3 forms a stable and reliable transmission structure through the cooperation of the driving seat 31, the bearing 32, and the shaft cover 33. This design not only enhances the stability of the entire transmission system but also improves the precision and reliability of the nano grinding wheel during operation.

[0066] The provision of the accommodating groove 311 enables the bearing 32 to be stably installed in the driving seat 31, and the shaft cover 33 effectively limits and protects the bearing 32. This design prevents the bearing 32 from falling off or being damaged during operation, prolongs the service life of the bearing 32, and reduces maintenance costs.

[0067] As shown in Figure 4 The shaft cover 33 of the present embodiment is provided with a shaft passing hole 331 that allows the nano grinding wheel to pass through,

[0068] The inner side of the shaft cover 33 is provided with an avoidance groove 332 for accommodating the bearing 32 and avoiding the bearing 32 rollers.

[0069] The shaft passing hole 331 provided on the shaft cover 33 provides a precise passage for the nano grinding wheel, ensuring that the nano grinding wheel can maintain an accurate position during installation and operation, improving the precision and stability of grinding.

[0070] The avoidance groove 332 on the inner side of the shaft cover 33 effectively avoids direct contact between the nano grinding wheel or transmission components and the bearing 32 rollers, reducing friction and wear, and prolonging the service life of the bearing 32.

[0071] As shown in Figure 4 The bottom of the driving transmission seat 3 of the present embodiment is provided with a sliding platform 4,

[0072] The sliding platform 4 includes a bearing plate 41, a guide rail 42, a sliding block 43, and a sliding plate 44. The bearing plate 41 is provided with a positioning groove 401, the guide rail 42 is fixed to the positioning groove 401, the sliding block 43 slides along the guide rail 42, the sliding plate 44 is fixed to the sliding block 43, and the sliding block 43 is connected to the driving transmission seat 3.

[0073] The sliding platform 4 provided at the bottom of the driving transmission seat 3 enables the driving transmission seat 3 to move freely in the horizontal direction, increasing the flexibility and adjustability of the equipment. This design makes it easier for the nano grinding wheel to achieve precise grinding of different positions or different shapes of workpieces.

[0074] The cooperation of the guide rail 42 and the sliding block 43 ensures the stability and precision of the driving transmission seat 3 during movement. The sliding block 43 slides along the guide rail 42, reducing friction and vibration during movement, and improving the precision and consistency of grinding.

[0075] The positioning groove 401 and the guide rail 42 work together to ensure that the guide rail 42 is installed precisely on the support plate 41, thereby improving the working accuracy of the sliding platform 4 and reducing the installation difficulty of the sliding platform 4.

[0076] like Figure 4 As shown, the edge of the slide plate 44 in this embodiment is provided with a positioning edge 441, and the active transmission seat 3 is connected to the inner side of the positioning edge 441. Through the cooperation of the positioning edge 441 and the active transmission seat 3, the connection between the slide plate 44 and the active transmission seat 3 is more precise, and the installation difficulty is reduced.

[0077] The guide rail 42 is provided with a first limiting block 421 for limiting the sliding range of the slider 43, and the support plate 41 is provided with a second limiting block 411 for limiting the sliding range of the slider 43.

[0078] The first limiting block 421 on the guide rail 42 and the second limiting block 411 on the support plate 41 together limit the sliding range of the slider 43, ensuring the accuracy of the position and stroke of the active transmission seat 3 during the movement process.

[0079] like Figure 1 As shown, this embodiment also includes a lifting component 5.

[0080] The lifting assembly 5 is equipped with a lifting drive 51, a fixing frame 52, and a lifting device 53.

[0081] The fixing brackets 52 are respectively fixed to the frame of the grinding equipment;

[0082] The lifting device 53 is fixed to the fixing frame 52;

[0083] The lifting driver 51 drives the lifting device 53 to lift and lower.

[0084] The lifting device 53 is used to drive the sliding platform 4, the active transmission seat 3, and the nano-grinding wheel to rise and fall.

[0085] The lifting assembly 5 enables flexible adjustment of the height of the sliding platform 4, the active drive seat 3, and the nano-grinding wheel. This allows the grinding equipment to adapt to workpieces of different heights or with different grinding requirements, improving the equipment's flexibility and applicability, and facilitating the adjustment of the grinding gap between the nano-grinding wheel and the driven wheel.

[0086] The lifting driver 51 drives the lifting device 53 to perform lifting operations, ensuring precise contact between the nano-grinding wheel and the workpiece during the grinding process. This reduces grinding errors caused by height mismatch and improves the accuracy and consistency of grinding.

[0087] The lifting driver 51 is a servo motor, and the jacking device 53 can be a screw lifting machine, a bevel gear screw lifting machine, a gear and rack lifting machine, a worm and gear lifting machine or a ball screw lifting machine to effectively convert the rotary motion into linear motion.
