Description

Tilting device of auxiliary magnetic table at the Grinding machine

The present invention relates to a device for adjusting the inclination angle of the auxiliary magnetic table of the grinding machine. In detail, the planar grinding method of the gradient or taper of the workpiece fixed to the auxiliary magnetic table is performed by rotating the auxiliary magnetic table at an arbitrary angle in the planar grinding machine. A subsidiary magnetic table tilt angle adjusting device for a grinding machine that enables machining.

In general, the grinding method is to use the outer periphery of the grindstone and to use the cross section of the grindstone. The former grinding machine mainly performs grinding rotational movement about the horizontal axis parallel to the plane to grind the grindstone. do.

The latter is mainly performed by grinding the grinding wheel around the side perpendicular to the plane to be ground and grinding on the bottom thereof.

In the vertical grinding process, the grinding wheel and the workpiece are in surface contact, so that there are many grinding particles working at the same time, and the grinding amount can be increased. Therefore, it is generally suitable for rough grinding work that requires the removal of a large amount of chips from the workpiece.

Horizontal grinding is suitable when the demand for roughness and dimensional accuracy of the finished surface is high. Both types include a reciprocating table type where the workpiece is installed in a linear reciprocating motion, and a rotary table type that rotates around a vertical axis. . In general, the reciprocating table type is mainly used.

In the reciprocating table type, the workpiece is fixed to a magnetic table fixed on the table and the table reciprocates in the horizontal direction.

The grinding depth can be adjusted by moving the whetstone shaft up and down, and the feeding is done by moving the grindstone shaft or the table in the front-rear direction.

Therefore, grinding of workpieces with a gradient or taper in the width direction of the grindstone becomes impossible.

In order to grind the workpiece with the gradient or taper formed by using a planar grinding machine, the auxiliary jig 110 suitable for the gradient is manufactured, attached to the magnetic table 10, and the workpiece 80 with the gradient on the jig 110 is placed. A method of grinding by forming the auxiliary plate 120 for mounting and preventing the separation of the workpiece on the front and rear surfaces of the workpiece is used.

However, the above-described method has a problem in that the auxiliary jig 110 and the auxiliary plate 120 should be manufactured and used for each workpiece according to the degree of gradient of the workpiece in the working process, and when the jig is used, the workpiece is caused by frictional heat between the grindstone and the workpiece. Fixed in the jig and thermally deformed, there was a problem of a safety accident in which the sharp breakage or the workpiece deviates from the jig during work in the thermally deformed state

Therefore, the technical problem to be solved by this paper is to solve the above problems and to adjust the inclination of the magnetic table so that the surface can be ground at any time regardless of the degree of draft or taper without using jig. It is to provide a magnetic table inclination angle adjusting device for grinding by adjusting the inclined to maintain a plane.
