Polishing machine with polishing sheet capable of being replaced quickly

Abstract

The invention discloses a polishing machine with a polishing sheet capable of being replaced quickly. The polishing machine comprises a main body shell. A head shell is welded to one side of the mainbody shell, and an auxiliary mounting hole is formed in the outer wall of one end of the head shell. A baffle of the semicircular structure is installed on the outer wall of the bottom of the head shell through a bolt. A first sliding chute opening is formed in the inner wall of the bottom of the head shell, and the inner wall of the first sliding chute opening is connected with an output shaft ina rotating mode. A clamping groove is milled in the side wall of the output shaft, and the bottom end of the circumferential outer wall of the output shaft is sequentially sleeved with an upper pressing plate, the polishing sheet and a lower pressing plate. The polishing machine is easy and fast to operate. Due to arrangement of a clamping block and the clamping groove, the output shaft can be fixed, and no monkey spanner is required any more when the polishing sheet is replaced. Due to arrangement of a limiting groove and a fixing groove, rotation of the output shaft cannot be affected. By adoption of the design, the polishing sheet can be better replaced quickly, accidental hand scratching caused by manual fixation of the output shaft can be avoided, reliability and safety are achievedand people can feel relieved.

Description

technical field [0001] The invention relates to the technical field of polishing machines, in particular to a polishing machine capable of rapidly replacing polishing sheets. Background technique [0002] Grinder is a kind of manual power tool used for metal surface grinding. Grinder is specially designed for the surface and tube of metal products such as steel, aluminum and copper. It is an important equipment in the metal product production line and the key to operation. It is necessary to try to get the maximum polishing rate in order to remove the damage layer produced during polishing as soon as possible, and at the same time, make the polishing damage layer not affect the final observed tissue, that is, it will not cause false tissue, and the long-term use of the polishing machine The polishing sheet needs to be replaced frequently in the machine. The polishing sheet used by the grinder is fixed by the upper and lower pressure plates. When changing the polishing sheet ...

[0002] Grinder is a kind of manual power tool used for metal surface grinding. Grinder is specially designed for the surface and tube of metal products such as steel, aluminum and copper. It is an important equipment in the metal product production line and the key to operation. It is necessary to try to get the maximum polishing rate so as to remove the damage layer produced during polishing as soon as possible, and at the same time make the polishing damage layer not affect the final observed tissue, that is, it will not cause false tissue, and the long-term use of the polishing machine The polishing sheet needs to be replaced frequently in the machine. The polishing sheet used by the grinder is fixed by the upper and lower pressure plates. When replacing the polishing sheet of the currently used grinder, the rotating shaft must be fixed with an adjustable wrench, and at the same time, the claw wrench is used to loosen it. The pressure plate requires two wrenches to be used at the same time to replace the polishing sheet, which is troublesome, and when the polishing sheet is replaced, the hand may be accidentally scratched during the process of stabilizing the polishing sheet
