Abstract

The invention provides an online arc-shaped abrasive wheel trimming device based on cup-shaped tool spherical surface envelope and relates to online trimming devices for arc-shaped abrasive wheels. The online arc-shaped abrasive wheel trimming device is used for solving the problems of the existing arc-shaped abrasive wheel trimming methods that the adaptable range is small, the device function is single, the accuracy of trimming is low and online trimming cannot be provided for arc-shaped abrasive wheel trimming. The online arc-shaped abrasive wheel trimming device comprises a first stepping motor, a second stepping motor, a connecting rack, a horizontal connecting plate, a rotating mechanism, a vertical moving mechanism and a horizontal moving mechanism, wherein the rotating mechanism comprises a speed reduction motor and a connecting assembly, the first stepping motor and the horizontal moving mechanism are mounted on the connecting rack, the vertical moving mechanism is connected with the connecting assembly, the speed reduction motor is mounted on the connecting assembly, and a cup-shaped copper electrode or cup-shaped abrasive wheel is mounted at an output terminal of the speed reduction motor ; the second stepping motor is mounted on the horizontal connecting plate, and the horizontal connecting plate is mounted on an abrasive wheel cover. The online arc-shaped abrasive wheel trimming device is applied to the online trimming of the arc-shaped abrasive wheels.

Description

technical field [0001] The invention relates to an on-line dressing device for an arc grinding wheel, in particular to an on-line dressing device for an arc grinding wheel based on the principle of the spherical enveloping track of a cup-shaped tool. Background technique [0002] Arc grinding wheels play an irreplaceable role in today's aspheric grinding, especially when grinding large-diameter optical mirrors. Since most optical devices are hard and brittle materials such as silicon carbide ceramics and optical glass, in the During the aspheric grinding process, the grinding wheel is seriously worn, which seriously affects the quality of aspheric grinding. In order to ensure the grinding accuracy and surface quality of the aspheric surface, the grinding wheel should maintain high arc profile accuracy and sharpness during the entire grinding process of the large-diameter aspheric surface. The dressing device can realize online dressing of the arc grinding wheel, so This tri...
