Problems solved by technology
[0003] At present, when the grinding machine is grinding the workpiece, as the grinding allowance of the workpiece gradually decreases until the grinding allowance is zero, the processing feed speed of the grinding wheel is always constant, and because the grinding wheel frame drives the feeding process of the grinding wheel , when the grinding wheel frame is controlled to stop feeding, the grinding wheel frame will move slightly due to the inertial effect, resulting in the loss of workpiece precision. The greater the feed speed of the grinding wheel frame, the greater the inertial effect, resulting in loss of workpiece accuracy The larger it is, the lower the machining accuracy of the workpiece

The invention discloses an on-line detecting device. The device comprises a rack, a grinding wheel frame slidably connected to the rack, a grinding wheel rotatably connected to the grinding wheel frame, a grinding wheel motor for controlling the grinding wheel to rotate and a servo motor for controlling the grinding wheel frame to move. The grinding wheel frame is located on one side of a workpiece, and a grinding allowance detecting device body for detecting the grinding allowance of the workpiece is connected to the position, at the other end of the workpiece, of the rack in a slipping mode in the direction perpendicular to the axis of the workpiece. The output end of the grinding allowance detecting device body is connected with a control module, the output end of the control module is connected with the servo motor, and a first grinding allowance, a second grinding allowance, a third grinding allowance and a fourth grinding allowance are set in the control module, wherein the first grinding allowance, the second grinding allowance, the third grinding allowance and the fourth grinding allowance are sequentially decreased, and the fourth grinding allowance is zero. Through the on-line detecting device, the machining accuracy of the workpiece is improved.
Description
technical field [0001] The invention relates to the technical field of grinding machines, more specifically, it relates to an online detection device. Background technique [0002] Cylindrical grinding machine is the basic type of common type, mainly used for grinding the outer surface of cylindrical workpieces. The machining accuracy of the workpiece is measured in microns. The difference between the diameter of the blank workpiece and the diameter of the standard workpiece is the grinding allowance. When the grinding allowance is zero, it means that the workpiece has been ground. [0003] At present, when the grinding machine is grinding the workpiece, as the grinding allowance of the workpiece gradually decreases until the grinding allowance is zero, the processing feed speed of the grinding wheel is always constant, and because the grinding wheel frame drives the feeding process of the grinding wheel , when the grinding wheel frame is controlled to stop feeding, the gri...
