The working principle of this high-precision chamfering grinder is:

First, the X-axis moving mechanism 13 drives the Y-axis moving mechanism 14 to advance under the transmission of the servo motor, and then the Y-axis moving mechanism 14 drives the Z-axis moving mechanism 15 and the manipulator 16 under the transmission of the servo motor, to one of the trays 19. After the workpiece is above the workpiece, the manipulator 16 drives the square cylinder 20 above the slider to move down to the position set by the program under the transmission of the servo motor. One of the finger cylinders on the manipulator 16 is equipped with a spring-pressing device to clamp the workpiece, and then the manipulator 16 returns. When the X-axis moving mechanism 13 moves back, the square cylinder 20 on the manipulator 16 pushes the rocker arm 17 to rotate 90°. After the X-axis moving mechanism 13 is in place, the Y-axis moving mechanism 14 drives the manipulator 16 to advance to the workpiece on the finger cylinder and The center of the main shaft of the working head 18 is aligned, and then the X-axis moving mechanism 13 advances to the workpiece on the finger cylinder and enters the limit position in the spindle chuck of the working head 18, the finger cylinder is opened, and the spring pressing device on the finger cylinder withstands the workpiece, working The push rod in the stainless steel mini cylinder on the head 18 main shaft returns to the position to drive the jaws to expand and drive the pull rod to pull the chuck back to clamp the workpiece. The X-axis moving mechanism 13 returns to the position, and the Y-axis moving mechanism 14 returns to the position at the same time Z The square air cylinder 20 on the shaft moving mechanism 15 returns.

The rotating base 10 first adjusts the required angle, and then advances to a certain position according to the program setting, when the grinding wheel 1 is driven, the first servo motor 7 drives the grinding wheel 1 to rotate, the servo motor of the working head 18 drives the main shaft to rotate, and the grinding wheel 1 advances to process according to the program. After the processing is in place, the emery wheel 1 returns, and the working head 18 stops rotating. At this time, the Y-axis moving mechanism 14 drives the manipulator 16 to advance until the finger cylinder of the manipulator 16 is parallel to the center of the main shaft of the working head 18, and then the Z-axis moving mechanism 15 pushes the slide block according to the program, and the finger cylinder without the clamped workpiece is aligned with the working head 18. The main shaft is centered, the X-axis moving mechanism 13 advances, and the manipulator 16 square cylinder 20 fingers on the Z-axis moving mechanism 15 clamps the processed workpiece, the X-axis moving mechanism 13 retreats, and the Z-axis moving mechanism 15 pushes the slider to move up and down. Align the center of one of the finger cylinders with the unprocessed workpiece with the center of the main shaft of the work head 18, and then the X-axis moving mechanism 13 advances the workpiece on the finger cylinder to the limit position in the work head 18 spindle chuck, and the fingers When the cylinder is opened, the elastic pressing device on the finger cylinder bears against the workpiece.
