Embodiment 1

[0029] Please refer to figure 2 , This embodiment provides a grinding and polishing machine spindle sealing structure, including the spindle 10, the spindle 10 is installed in the spindle sleeve 8 through the upper bearing 1 and the lower bearing 2, the top of the spindle 10 is connected with the turntable locking screw 13 A turntable 14 is connected and fixed. The turntable locking screw 13 is fixed with a rubber cap 11 by a rubber cap screw 12, and the rubber cap 11 is buckled on the turntable 14 so that the lower edge of the rubber cap 11 contacts the turntable 14. The top of the main shaft 10 extends out of the main shaft sleeve 8 and is fixedly connected with a dust cover 2. The bottom of the turntable 14 is in close contact with the top surface of the dust cover 2. The connecting position of the dust cover 2 and the main shaft 10 is provided with a sealing ring d15.

[0030] The cross section of the dust cover 2 is a symmetrical L shape with the edge downward. A sealing...

Abstract

The invention discloses a spindle sealing structure of a grinding and polishing machine. The spindle sealing structure comprises a spindle. The spindle is mounted in a spindle sleeve through bearings,the top end of the spindle stretches out of the spindle sleeve and is fixedly connected with a dust cover, a sealing ring b is arranged between the end, close to the top of the spindle, of the innerwall of the spindle sleeve and the spindle, and a sealing ring a and a sealing ring c are sequentially arranged between the outer wall of the spindle sleeve and the dust cover from top to bottom. Thedust cover, the sealing ring a and the sealing c can rotate along with the spindle. The sealing structure has the main effects that a grinding medium, dust, water and the like in a barrel seat and ona rotary disc are prevented from entering the bearings, thus, abnormal abrasion of the bearings caused thereby is avoided, and the service life of the equipment is prolonged.

Description

Technical field [0001] The invention relates to the technical field of grinding and polishing machinery, in particular to a main shaft sealing structure of a grinding and polishing machine. Background technique [0002] Grinding and polishing machines are also known as finishing machines. They are generally used for surface processing such as grinding, polishing, and deburring of semi-finished products of mechanical parts, jewelry, watches and other products. The whirlpool type grinding and polishing machine is also called the mobile light decoration machine, or the vortex type or eddy current type light decoration machine. The basic structure of the vortex grinding and polishing machine includes a motor, a spindle connected to the motor, a turntable connected to the spindle, and a fixed barrel surrounded by the turntable. The high-speed rotation of the turntable drives the workpiece to be ground in the fixed barrel to rotate with the grinding medium to make grinding The medium ...
