Technical Field

[0001] The utility model relates to the technical field of supporting tables for polishing and grinding, in particular to a machine base for assisting polishing and grinding. Background Art

[0002] Polishing and grinding are processes that enhance the smoothness and gloss of a workpiece's surface. First, coarse sandpaper or abrasives are used to remove surface imperfections and unevenness. Fine sandpaper or polishing paste is then used to further refine the surface, and finally, a polishing cloth or wheel is used to achieve a high gloss. During the polishing and grinding process, an auxiliary polishing machine base is required to support the workpiece, placing it on the base for polishing.

[0003] However, the existing auxiliary polishing and grinding machine base has the following disadvantages. Since most polishing and grinding machine bases that carry workpieces are usually composed of a base and a grinding workbench, during the polishing and grinding process, other surfaces of the workpiece may need to be polished and ground, and the staff needs to move the workpiece to adjust the orientation, which is not very convenient. Therefore, the current auxiliary polishing and grinding machine base needs to be improved. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. An adjustment mechanism is provided. By pulling the limit rod to one side, the limit rod drives the support spring to contract, so that one end of the limit rod disengages from the limit hole, and then the grinding table is rotated. At the same time, the grinding table contacts the ball, so that the grinding table drives the rotating shaft to rotate, and the rotating shaft drives the turntable to rotate. The grinding table can drive the workpiece to be adjusted in multiple directions. After adjusting to the appropriate position, the limit rod is released, and the support spring rebounds to drive one end of the limit rod to insert into the limit hole, limiting the position of the turntable. The position of the grinding table and the workpiece can be quickly adjusted, which is convenient for the staff to quickly polish and grind other surfaces of the workpiece, thereby improving the convenience of the polishing and grinding machine base.

[0014] 2. An installation mechanism, a No. 1 clamping ring and a No. 2 clamping ring are provided. When the protective film is removed from the polishing table, the fastening ring can be rotated to make the fastening ring and the screw engage with each other, and the fastening ring can be removed from the screw. Then, the screw can be removed from the No. 1 clamping ring and the No. 2 clamping ring. The No. 1 clamping ring and the No. 2 clamping ring can be quickly separated. Then, the No. 1 clamping ring and the No. 2 clamping ring can be pulled to both sides to remove the No. 1 clamping ring and the No. 2 clamping ring from the polishing table. The protective film is freed from the restriction of the No. 1 clamping ring and the No. 2 clamping ring, which facilitates the removal of the protective film for replacement, thereby improving the practicality of the machine base for polishing and grinding.

[0023] In specific implementation, since most polishing and grinding machine bases that carry workpieces are usually composed of a base 1 and a polishing workbench, during the polishing and grinding process, it may be necessary to polish and grind other surfaces of the workpiece, and the staff needs to move the workpiece to adjust the orientation, which is not very convenient. The limit rod 603 can be pulled to one side to cause the limit rod 603 to drive the support spring 604 to contract, so that one end of the limit rod 603 is disengaged from the limit hole 602, and then the polishing table 3 is rotated. At the same time, the polishing table 3 contacts the ball 605, so that the polishing table 3 drives the rotating shaft 601 to rotate, and the rotating shaft 601 drives the turntable 9 to rotate, so that the polishing table 3 can drive the workpiece to be adjusted in multiple directions. After adjusting to the appropriate orientation, the limit rod 603 is released, and the support spring 604 rebounds to drive one end of the limit rod 603 to insert into the limit hole 602, limiting the position of the turntable 9, and the orientation of the polishing table 3 and the workpiece can be quickly adjusted, which is convenient for the staff to quickly polish and grind other surfaces of the workpiece, thereby improving the convenience of the polishing and grinding machine base.

[0024] See also Figure 2 and Figure 4 The upper surface of the grinding table 3 is covered with a protective film 7, and the outer sides of the protective film 7 and the grinding table 3 are sleeved with a No. 1 snap ring 4 and a No. 2 snap ring 5.
