Automatic changing device of grinding wheel and grinding wheel cover of vertical internal and external grinding machine

Abstract

The invention relates to an automatic changing device of a grinding wheel and a grinding wheel cover of a vertical internal and external grinding machine, wherein a body shell is fixed on a machine body, a servo motor is installed below the body shell, an output shaft of the servo motor is connected with an input shaft of a speed reducer through a transmission shaft located in the body shell, and the output shaft of the speed reducer is connected with a grinding wheel mounting disk; a rotating shaft is installed in the grinding wheel mounting disk; the upper end of the rotating shaft is connected with a grinding wheel cover mounting disk through a clutch, the clutch is connected with a cylinder piston rod through a guide sleeve and a guide shaft, a cylinder is fixedly connected with a clutch shell through a cylinder seat, and a spring is installed between the clutch shell and the grinding wheel cover mounting disk. According to the automatic changing device provided by the invention, the grinding wheel and the grinding wheel cover of the vertical internal and external grinding machine can be changed automatically; the operation of changing a grinding wheel turntable and a grinding wheel cover turntable is switched by the clutch, and the operations can not interfere each other during the changing process; the clutch is controlled by the cylinder and the spring; and the mechanism is driven by a numerical control servo motor, and the rotating and locating precision of the grinding wheel and the grinding wheel cover are high.

Description

technical field [0001] The invention relates to a machine tool accessory, in particular to a grinding wheel and grinding wheel cover replacement device for a vertical internal and external grinding machine. Background technique [0002] At present, the vertical internal and external cylindrical grinding machines produced by domestic manufacturers can only be installed and replaced by manual installation and replacement of grinding wheels and grinding wheel covers, which takes a long time for grinding assistance and is labor-intensive. And from patent and actual use situation, do not see the device that can automatically carry out grinding wheel and grinding wheel cover replacement at present. Contents of the invention [0003] In order to realize the automatic replacement of the grinding wheel and the grinding wheel cover of the vertical inner and outer cylindrical grinding machine, the invention provides an automatic replacement device for the grinding wheel and the grind...

AI Technical Summary

Problems solved by technology

[0002] At present, the vertical internal and external cylindrical grinding machines produced by domestic manufacturers can only be manually installed and replaced by the grinding wheel and the grinding wheel cover. The grinding auxiliary time is long and the labor intensity is high.

From the perspective of patents and actual usage, there is no device that can automatically replace the grinding wheel and the grinding wheel cover.
