High-precision and high-stability surface grinding machine

Abstract

The high-precision and high-stability surface grinding machine is provided with a first base and a second base, sliding rail seats are fixedly arranged on the left side and the right side of the upper end of the second base respectively, a stand column is arranged between the two sliding rail seats, and stand column supporting plates are arranged in the middles of the left side and the right side of the stand column respectively. The two stand column supporting plates and the two sliding rail seats are in sliding connection through sliding rails correspondingly. In an existing surface grinding machine, due to the fact that related parts connected with a grinding wheel are all fixed to a stand column, and a sliding rail is located at the bottom of the stand column, the sliding rail bears large longitudinal load, and when the grinding wheel machines a workpiece with high hardness and high machining precision requirement, the stand column lacks of transverse support. And irregular shaking of a grinding wheel, a main shaft and a stand column is caused, the surface of a workpiece is uneven, and the requirement for machining precision of the workpiece is difficult to meet. The high-strength grinding device can be widely applied to high-strength grinding of the surface grinding machine.

[0002] Surface grinder is a common metal processing equipment. Its main function is to grind metal materials to achieve the requirements of flatness and precision. It is widely used in manufacturing, aviation, automobile manufacturing, general machinery and tool manufacturing. When the surface grinder is running, the slide rail drives the worktable, column and spindle to move in the X, Y and Z axis directions respectively.

[0003] In the existing surface grinder, a slide rail is installed at the bottom of the column to drive the column to move along the Y-axis direction. However, in this structural arrangement, since the relevant components connected to the grinding wheel are fixed on the column and the slide rail is located at the bottom of the column, the slide rail is subjected to a large longitudinal load. When the grinding wheel processes a workpiece with high hardness and high processing accuracy requirements, the column lacks lateral support, resulting in irregular shaking of the grinding wheel, the spindle and the column, resulting in an uneven surface of the workpiece, making it difficult to meet the processing accuracy requirements of the workpiece.
