For improving the utility model discloses a work efficiency guarantees the contact between part and the polishing video disc, ensures processingquality, drive bearing 2 has certain flexible volume in motor 1.

For improving the utility model discloses a processingquality and work efficiency, screw 9 passes objective table 8, and one end is located the objective table outside, and dog 7 is connected to the other end. The stop block 7 and the workpiece 6 are tightly connected through a screw, so that the workpiece is effectively fixed. Meanwhile, one end of the screw is located on the outer side of the objective table, so that the screw is convenient and rapid to adjust.

In order to ensure the fixation between the stop block and the workpiece and ensure the processing quality, a sliding groove matched with the stop block is arranged in the groove.

The utility model discloses a fix the work piece on the objective table, control the height of objective table through rotatory hand wheel, make work piece and polishing video disc contact, will polish the video disc at the uniform velocity rotation through the effect of motor again, make polishing video disc and work piece produce relative slip and then polish workpiece surface.

The specific operation process is as follows: the device is firstly installed on a worktable with better flatness, the height of an objective table is reduced by rotating a hand wheel, and when a workpiece is placed at the center of the objective table, the workpiece is ensured not to contact with a polishing disc. The stop blocks are added on two sides of the workpiece, the height of the stop blocks is ensured to be lower than that of the workpiece, and if the height of the stop blocks is higher than that of the workpiece, a gasket with better finish degree needs to be added on the bottom of the workpiece. And then the stop block is contacted with two side surfaces of the workpiece through the screw, and the screw is screwed down to fix the workpiece on the carrying table surface. In the process, the workpiece and the polishing disc are ensured to be on the same horizontal plane as much as possible, the horizontal sliding groove is formed in the carrying table surface, and the stop block is embedded in the sliding groove, so that the parallelism of the stop block can be ensured, and the workpiece is not inclined in the pressing process. Then the rotary wheel is rotated to lift the table surface of the object stage, and when the workpiece is connected with the polishing disc, the rotary wheel is slightly rotated to provide a downward force for the workpiece. At this time, the polishing disk is subjected to an upward force due to the interaction of the forces, and tends to move upward. The motor is fixed on the fixed support, and the polishing disc and the workpiece are in a balanced state under the action of the elastic force of the spring when the rotating bearing is not fixed in the motor due to a certain telescopic amount in the motor. Finally, the power supply of the motor is switched on, the polishing disc is driven by the rotating bearing to rotate at a constant speed, so that the polishing disc and the workpiece slide relatively, and the polishing effect is achieved.

Because the transmission bearing is in an unfixed state in the motor and has a certain expansion amount, the polishing disc and the workpiece are in a balanced state under the action of the elastic force of the spring, and the polishing disc gives a downward force to the workpiece and avoids the situation of mutual butting so as to influence the normal use of the polishing machine. The smooth finish of the surface of the sliding groove is good, and the stop block can freely slide in the sliding groove without the phenomenon of blocking. The surface of the objective table is smooth and has no foreign matters, the surface of the workpiece to be polished is in a horizontal state, and the polishing plane and the polishing disc are in the same horizontal plane during polishing. The objective table is the recess design, and the fixed of cooperation dog can be placed a plurality of parts in wherein simultaneously, improves machining efficiency. Before polishing, the height of the workpiece is ensured to be higher than that of the stop block, and the workpiece is ensured to be fixed on the objective table and cannot be loosened.

The automatic part polishing device with the structure has the advantages that 1) the labor intensity of an operator is reduced, and the full-automatic polishing of the surface of a workpiece can be realized only by fixing the workpiece on the objective table; 2) the polishing precision of the surface of the workpiece is ensured, the force between the part and the polishing disc is relatively stable only by adjusting the relative positions of the workpiece, the objective table and the polishing disc, and the phenomenon that the surface of the part inclines is avoided; 3) the working efficiency is improved, a plurality of parts with the same height can be polished simultaneously, and the consistency of the heights of the parts is ensured while the working efficiency is improved; 4) the stability and the qualification rate of the surface precision of the workpiece are ensured.
