[0002] A grinding and polishing machine is a commonly used grinding and polishing mechanical device, which is widely used in the surface treatment processes of materials such as metals, glasses, and ceramics. A polishing disc or polishing cloth for grinding and polishing is arranged on the workbench of the grinding and polishing machine, so that the polishing disc or polishing cloth rubs back and forth on the surface of the product, thereby removing scratches and defects on the surface of the product, and at the same time improving the smoothness and flatness of the product surface.
[0003] During the grinding and polishing process, a liquid is required to cool and lubricate the upper grinding disc. In order to ensure the cooling and lubrication effects, a polishing liquid is required to uniformly and continuously lubricate the upper grinding disc. Some existing liquid lubrication and cooling methods are difficult to make the polishing liquid flow uniformly and continuously on the surface of the upper grinding disc, and it is easy to occur that some local areas are difficult to be fully lubricated. Therefore, how to make the liquid uniformly and continuously lubricate and cool the upper grinding disc still needs further research. Summary of the Utility Model

[0007] Preferably, the hoisting mechanism includes an upper mounting plate, a lower mounting plate, and a suspension rod. Both the top and bottom of the suspension rod are provided with mounting holes, and both the upper mounting plate and the lower mounting plate are provided with through mounting holes; the suspension rod is arranged between the mounting plate and the lower mounting plate, the suspension rods are uniformly distributed in the circumferential direction of the sub-mounting plate and the lower mounting plate, and the upper mounting plate, the suspension rod, and the lower mounting plate are connected into a whole through bolts.

[0018] The following further describes the present utility model in conjunction with embodiments and drawings: Embodiment 1
[0019] As shown in Figure 1 , Figure 2 and Figure 3As shown in the figure, the liquid lubrication device of the upper grinding disc 8 on the grinding machine includes a water distribution tank 1, a water distribution pipe 3 and a hoisting mechanism. The water distribution tank 1 is an annular body with an open upper end, and the vertical cross-section of the water distribution tank 1 is U-shaped. The bottom of the water distribution tank 1 is provided with through water distribution holes 9, and the water distribution holes 9 are evenly distributed in the circumferential direction of the bottom of the water distribution tank 1. The upper grinding disc 8 is also provided with through water distribution holes 9, and the water distribution holes 9 of the upper grinding disc 8 are evenly distributed in the circumferential and radial directions of the upper grinding disc 8. Such a distribution is to ensure that the liquid flowing out of the water distribution holes 9 can lubricate the entire bottom of the upper grinding disc 8 as evenly as possible. The number of water distribution holes 9 opened in the water distribution tank 1 is the same as the number of water distribution holes 9 opened on the upper grinding disc 8, and both ends of the water distribution pipe 3 are respectively inserted into the water distribution holes 9 of the water distribution tank 1 and the upper grinding disc 8 to ensure that the liquid flowing downward from any water distribution hole 9 on the water distribution tank 1 can flow to the bottom of the upper grinding disc 8 through a water distribution pipe 3.
[0020] The hoisting mechanism includes an upper mounting plate 2, a lower mounting plate 7, an ultrasonic vibrator 6 and a suspension rod 5. Both the top and bottom of the suspension rod 5 are provided with mounting holes, and both the inner sides of the upper mounting plate 2 and the lower mounting plate 7 are provided with through mounting holes. The number of mounting holes on the inner sides of the upper mounting plate 2 and the lower mounting plate 7 corresponds to the number of suspension rods 5, and the positions of the mounting holes on the inner sides of the upper mounting plate 2 and the lower mounting plate 7 are also corresponding, so that the length direction of the installed suspension rod 5 is consistent with the vertical direction. The suspension rod 5 is arranged between the mounting plate and the lower mounting plate 7, and the suspension rod 5 is evenly distributed in the circumferential direction of the sub-mounting plate and the lower mounting plate 7, and the upper mounting plate 2, the suspension rod 5 and the lower mounting plate 7 are connected into a whole by bolts.
[0021] The ultrasonic vibrator 6 is fixedly connected to the top of the lower mounting plate 7, and the ultrasonic vibrator 6 is evenly distributed in the circumferential direction of the lower mounting plate 7. The lower mounting plate 7 is provided with a through mounting hole, and the inner side of the upper grinding disc 8 is provided with a corresponding through mounting hole. Bolts pass through the mounting holes of the lower mounting plate 7 and the upper grinding disc 8 to fixedly connect the lower mounting plate 7 and the upper grinding disc 8 into a whole. Starting the ultrasonic vibrator 6 can make both the lower mounting plate 7 and the upper grinding disc 8 generate high-frequency vibrations, so that the liquid at the bottom of the upper grinding disc 8 flows more evenly in all directions, thereby ensuring that the entire bottom surface of the upper grinding disc 8 can be fully and continuously lubricated.
[0022] As Figures 1 to 5 shown in the figure, an installation plate 4 is also used to fixedly connect the bottom of the water distribution tank 1 and the outer side of the upper mounting plate 2. The installation plate 4 is T-shaped, and the installation plate 4 is provided with a through mounting hole. Through mounting holes matching the mounting holes on the installation plate 4 are opened on the bottom of the water distribution tank 1 and the outer side of the upper mounting plate 2. Bolts pass through the mounting holes of the water distribution tank 1, the mounting plate and the installation plate 4 to fixedly connect the water distribution tank 1, the mounting plate and the installation plate 4 into a whole.
[0023] In this embodiment, in order to lubricate the bottom of the upper grinding disc 8, a liquid lubricating device is installed above the upper grinding disc 8, and liquid is injected into the water distribution tank 1, so that the liquid flows to the bottom of the upper grinding disc 8 through the water distribution pipe 3. However, the water distribution pipe 3 is not suitable for lifting the upper grinding disc 8, and even less suitable for transmitting the force to drive the rotation of the upper grinding disc 8, because this is likely to cause the connection between the water distribution pipe 3 and the water distribution holes 9 to become loose or even detached. The upper mounting plate 2 of the hoisting mechanism is fixedly connected to the water distribution tank 1 through the mounting plate 4, and the lower mounting plate 7 of the hoisting mechanism is fixedly connected to the upper grinding disc 8 through bolts. In this embodiment, mounting holes are also provided inside the upper mounting plate 2 for connecting a flange (the motor and the flange are not shown), and the flange is connected to the rotating shaft of the motor. Therefore, it is the motor that drives the flange, the upper mounting plate 2, the suspension rod 5, the lower mounting plate 7 and the upper grinding disc 8 to rotate in sequence. Therefore, the hoisting mechanism provided between the water distribution tank 1 and the upper grinding disc 8 is used both for lifting the upper grinding disc 8 and for transmitting the force to drive the rotation of the upper grinding disc 8.
[0024] Obviously, without departing from the principle described in the present invention, several improvements or modifications made should be regarded as within the protection scope of the present invention.
