DETAILED DESCRIPTION

[0041] The utility model is described in detail below in combination with the drawings.

[0042] As Figures 1 to 4 shown, the utility model relates to a kind of nano grinding wheel lifting assembly mechanism, including nano grinding wheel 100, shaft support rotating mechanism 200 and lifting assembly 300, shaft support rotating mechanism 200 is respectively set in the both sides of nano grinding wheel 100, nano grinding wheel 100 is rotatably connected with shaft support rotating mechanism 200, lifting assembly 300 is used to drive shaft support rotating mechanism 200 and nano grinding lifting, it is characterized in that: lifting assembly 300 includes lifting driver 301, linkage rod 302, two fixed frames 303 and two synchronous jacking devices 304,

[0043] Two fixed frames 303 are respectively fixed in the both sides of the rack of grinding equipment, wherein lifting driver 301 is servo motor.

[0044] Two synchronous jacking devices 304 are fixedly connected with two fixed frames 303 respectively one by one.

[0045] Linkage rod 302 is connected between synchronous jacking device 304.

[0046] Lifting driver 301 is simultaneously driven synchronous jacking device 304 synchronous work by linkage rod 302.

[0047] Synchronous jacking device 304 is used to drive shaft support rotating mechanism 200 and nano grinding wheel 100 lifting.

[0048] The nano grinding wheel lifting assembly mechanism connects the two synchronous jacks 304 through the linkage rod 302, ensuring that the lifting assembly 300 can work simultaneously and synchronously. This effectively avoids the asynchronous phenomenon during the lifting process of the lifting assembly 300, thereby improving the synchronization and stability of the lifting of the nano grinding wheel 100, which is conducive to ensuring the precision of the grinding operation.

[0049] Compared with traditional lifting mechanisms, this mechanism reduces complex transmission components through integrated design, thereby simplifying the overall structure. This not only reduces manufacturing costs, but also reduces maintenance complexity and costs, improving the reliability and service life of the equipment.

[0050] The lifting drive 301 directly drives the synchronous jacks 304 through the linkage rod 302, reducing intermediate transmission links, making the lifting action more rapid and efficient. This design is conducive to achieving rapid lifting of the nano grinding wheel 100, improving the efficiency of the grinding operation.

[0051] In use, the lifting drive 301 transmits power to the two synchronous jacks 304 through the linkage rod 302, enabling them to work simultaneously and synchronously. The synchronous jacks 304 drive the shaft support rotation mechanism 200 and the nano grinding wheel 100 to perform lifting motion through lifting or lowering. Due to the presence of the linkage rod 302, the synchronization of the two synchronous jacks 304 is ensured, thereby ensuring the stability and precision of the lifting of the nano grinding wheel 100.

[0052] As shown in Figure 2 The synchronous jack 304 of the present embodiment includes a lifting housing 305, a lifting rod 306, a drive shaft 307, and a linkage connector 308, all of which are arranged in the lifting housing 305 and are transmissionally connected to each other.

[0053] The lifting housing 305 is fixedly connected to the fixed frame 303;

[0054] The linkage rod 302 is fixed between the linkage connectors 308 of the two synchronous jacks 304;

[0055] The lifting drive 301 is transmissionally connected to the drive shaft 307;

[0056] The lifting rod 306 is connected to the shaft support rotation mechanism 200.

[0057] By designing the synchronous jack 304 to include the lifting housing 305, the lifting rod 306, the drive shaft 307, and the linkage connector 308, and transmissionally connecting the lifting rod 306, the drive shaft 307, and the linkage connector 308 to each other, the compactness and integration of the structure are achieved. This design not only reduces space occupation, but also improves the overall stability and reliability of the equipment.

[0058] The linkage rod 302 is fixed between the linkage connectors 308 of the two synchronous lifters 304, ensuring the synchronization of the lifting action. At the same time, the lifting driver 301 is in transmission connection with the driving shaft 307, so that the lifting action can be accurately controlled, further improving the precision and stability of the lifting of the nano grinding wheel.

[0059] Specifically, the lifting rod 306 is provided with a rack, the linkage connector 308 is provided with a gear, and the driving shaft 307 is connected with the linkage connector 308 through a shaft sleeve. When the driving shaft 307 rotates, the gear of the linkage connector 308 will drive the lifting rod 306 to rise or fall, so that the lifting rod 306, the driving shaft 307 and the linkage connector 308 are in transmission connection with each other, and at the same time, the rotation motion is converted into lifting motion.

[0060] As shown in Figure 3 and Figure 4 The shaft support rotating mechanism 200 of the embodiment includes a driven shaft support rotating mechanism 201,

[0061] The driven shaft support rotating mechanism 201 is provided with a fixed seat 1, a guide sliding piece 2, a swing connecting piece 3 and a bearing seat 4,

[0063] The bearing seat 4 is fixed to the swing connecting piece 3 and is used to be in rotational connection with the nano grinding wheel 100.

[0064] Through the combination of the swing connecting piece 3 and the guide sliding piece 2, the guide sliding piece 2 is arranged along the axial direction of the nano grinding wheel 100, so that the nano grinding wheel 100 connected to the bearing seat 4 can slide axially following the swing of the swing connecting piece 3. This mechanism not only supports the rotational motion of the nano grinding wheel 100, but also realizes the swing of the grinding wheel, thereby meeting the demand for multi-dimensional grinding of complex grinding processes, especially in occasions requiring both rotational grinding and axial grinding.

[0065] Compared with the traditional grinding wheel support mechanism which only supports single rotational motion, the design of this mechanism is more flexible, which can adapt to more types of grinding tasks, and improves the universality and adaptability of the equipment.

[0069] By setting the first positioning groove 11 on the fixed base 1 and fixing the guide rail 21 therein, the accurate positioning of the guide 2 is ensured. This design not only improves the overall stability of the mechanism, but also helps to achieve more accurate motion control.

[0070] The sliding connection design of the guide block 22 and the guide rail 21 enables the swing connecting piece 3 to slide smoothly and stably along the predetermined trajectory. This reduces friction and resistance during movement, improves the motion efficiency and service life of the mechanism.

[0071] The introduction of the limiting piece 23 effectively limits the sliding range of the guide block 22, preventing damage to the mechanism or loss of control of the grinding wheel due to excessive sliding. This not only improves the safety of the mechanism, but also enhances its reliability.

[0074] By fixing the guide block 22 to the second positioning groove 31, the accurate connection between the swing connecting piece 3 and the guide 2 is ensured, further improving the stability of the entire mechanism. At the same time, this connection method also helps to achieve more accurate motion control, improving the positioning accuracy of the grinding wheel.

[0075] Fixing the bearing seat 4 to the inner side of the limiting edge 32 simplifies the installation process and reduces the installation difficulty. At the same time, it is convenient for daily maintenance and maintenance.

In particular, the bearing pressing block 43, which is at least two in number, is fixed to the two sides of the seat body 41 and partially covers the accommodating cavity, effectively enhancing the support strength of the bearing seat 4 and improving the stability and durability of the overall structure.

[0080] The bearing 42 is arranged in the accommodating cavity, and the design of the bearing pressing block 43 not only stabilizes the bearing 42, but also makes the installation and disassembly process of the bearing 42 more convenient. This helps to reduce maintenance costs and improve work efficiency. At the same time, the arrangement of the bearing top block 44 also facilitates the positioning and support of the bearing 42, further simplifying the installation process.

The shaft rod passage 45 facilitates the connection of the nanometer grinding wheel 100 with the bearing seat 4, achieving rapid installation.

[0082] As shown in Figure 4 , the inner side of the bearing pressing block 43 of the present embodiment is provided with a first contact surface 431 and a shielding avoidance groove 432,
