Novel numerically controlled special-shaped glass edge grinding machine

Abstract

The invention provides a novel numerically controlled special-shaped glass edge grinding machine. A glass workpiece is adsorbed on a frame; a portal frame sliding along the Y axis is mounted on the frame; an X-axis sliding plate sliding along the X axis is mounted on the portal frame; a Z-axis sliding plate sliding up and down along the Z axis is mounted on the X-axis sliding plate; a main shaft mechanism is mounted on the Z-axis sliding plate; a tilt-angle main shaft sleeve is fixed on the Z-axis sliding plate; a tilt-angle main shaft is mounted in the tilt-angle main shaft sleeve; one end of the tilt-angle main shaft is in driving connection with a tilt-angle servo motor, while the other end of the tilt-angle main shaft is connected with a tilt-angle rotating stand; a transversely sliding assembly is arranged on the tilt-angle rotating stand; a grinding head motor is connected to the transversely sliding assembly by use of a transversely sliding plate; an elastic compensation assembly for driving the transversely sliding plate to slide front and back is connected to one side of the transversely sliding plate; a cutting tool is mounted on the output shaft of the grinding head motor; an automatic grinding wheel compensation function can be realized, so that the cutting tool is always held down in contact with the glass workpiece in the grinding process; as a result, a consistent grinding effect can be achieved, and the glass workpiece can be consistent in smoothness after being ground.

Description

technical field [0001] The invention relates to the technical field of a numerically controlled special-shaped glass edging machine, in particular to a new numerically controlled special-shaped glass edging machine with better edging and polishing effects. Background technique [0002] At present, flat glass can only become glass products after deep processing such as cutting, drilling, edging, polishing, coating, and tempering. Since the edges of the cut glass are uneven and have sharp edges, they need to be trimmed by edging and polishing. Therefore, edging and polishing are an indispensable step in the deep processing of glass. [0003] However, the development of domestic glass edging machine tools is still relatively backward. There are mainly several edging methods for glass special-shaped edging machines: manual edging, imitation-shaped edging, and CNC system compensation edging, among which 1) manual edging The requirements for operators are relatively high, and exp...

[0003] However, the development of domestic glass edging machine tools is still relatively backward. There are mainly several edging methods for glass special-shaped edging machines: manual edging, imitation-shaped edging, and CNC system compensation edging, among which 1) manual edging The requirements for operators are relatively high, and experienced and skilled workers are often needed, otherwise the defective rate is high, and it is only suitable for single-piece production, and the processing efficiency is low. , it is also difficult to ensure the consistency and smoothness of edging; 2) When processing by imitating shape edging, each set of profiles can only be processed with one product, which requires high precision processing, high cost, and limited functions For example, when processing the beveled edge with a straight line and curve mixed contour, it is difficult or even impossible to grind the edge. For the edge of the contour with a small radius of curvature, it is easier to distort the shape; 3) The current domestic CNC system compensation edge grinding technology is through Estimate the wear value of a grinding wheel at a certain grinding length, and then compensate it back. This compensation value is a fixed value. However, in the actual processing process, due to the different roughness of each glass processing edge and The wear resistance of each grinding wheel is different, which will cause a great difference between the wear value of the grinding wheel and the compensation value at a certain grinding length. The fixed NC trajectory coordinate line continues to shift, but because a certain glass edge is relatively rough, the loss value of the grinding wheel is very large, exceeding the compensation value of the system, resulting in a gradual decrease in the contact area between the workpiece to be ground and the grinding wheel in the second half, and even Completely inaccessible, making the smoothness of the entire workpiece processing surface inconsistent, seriously affecting the grinding effect
