The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings.

Referring to fig. 1 and 2, an embodiment of the present invention provides an automatic measuring device for a grinding machine, which includes a rotary power member 100, a measuring arm 200, a measuring head 300, and a support 400 disposed on a Z-axis assembly 500 of the grinding machine; the rotary power member 100 is disposed on the mount 400; the measuring arm 200 is connected to the output end of the rotary power member 100, and the end of the measuring arm 200 away from the rotary power member 100 is connected to the measuring head 300.

When the grinding machine is used specifically, a worker or a manipulator puts a workpiece 700 to be machined into the grinding machine, then the rotary power part 100 starts to work, the measuring arm 200 is driven to rotate, the measuring arm 200 drives the measuring head 300 to rotate, the measuring head 300 is in a vertical state, then the Z shaft assembly 500 of the grinding machine drives the measuring head 300 to descend, and the X shaft assembly and the Y shaft assembly of the grinding machine can drive the workpiece 700 to move, so that the measuring head 300 can measure the size of the workpiece 700, then the grinding machine processes the workpiece according to measured data, and in a state that the rotation of a grinding wheel does not stop, the measuring head 300 can measure the workpiece, so that grinding parameters are corrected, the processing quality of the grinding machine is improved, and through the arrangement, the workpiece 700 size does not need to be manually measured by the worker.

In the prior art, the measurement of the dimensions is carried out manually to ensure that the machining tolerances are within, but this is inefficient and has artificial measurement errors. The automatic measuring device for the grinding machine provided by the embodiment uses the measuring head 300 to automatically measure the size of the supplied workpiece 700 and the size after grinding, and can perform size compensation reprocessing according to the measurement result after grinding, thereby avoiding the occurrence of manual size measurement error and workpiece 700 scrapping, and simultaneously recording the grinding size data of each workpiece for subsequent quality tracing.

In addition, in the prior art, when a worker manually measures the size of a material, the grinding machine needs to be stopped, and the like, while a common grinding machine needs to be operated by an old master with a certain grinding experience, the machine tool is complex and cumbersome to operate, and the machine tool is not easy to operate, so that when the machine tool is stopped to measure the size of a workpiece 700, misoperation is easy to occur, the machine tool is collided, and equipment is damaged. The automatic measuring device of the grinding machine provided by the embodiment can better avoid the above problems by adopting the measuring head 300 to automatically measure.

Before grinding, the grinding wheel is dressed, and the workpiece 700 starts to be ground after the grinding wheel is dressed. After the grinding of the workpiece 700 is finished, the measuring arm 200 measures in the state that the grinding wheel rotates without stopping (the grinding wheel moves upwards along the Z axis of the grinding machine), similarly, the magnetic attraction is firstly performed at the designated position of the working platform 600 (the magnetic attraction is performed at the inner left upper corner of the working platform 600), then the workpiece 700 is measured at three points, the measured value can be displayed on a human-computer interface, and the flatness value of the workpiece 700 is calculated at the same time, so that three conditions exist: a. if the size is qualified, finishing grinding, automatically opening a machine tool door, and discharging; b. if the measured dimension is out of tolerance, the measuring system can automatically compensate the dimension, the grinding wheel is dressed after compensation, grinding machining and repairing are carried out, and the measurement is carried out after repairing until the dimension is within the tolerance range; c. if the measured size is small, the measurement system can also perform size compensation, give an alarm, display that the size is out of tolerance and abnormal, finish grinding and process the workpiece by an operator.

Among them, the measuring head 300 may employ a dragon measuring head 300.
