Precise composite molding grinding machine for numerical control linear guide rail

Abstract

The invention discloses a precise composite molding grinding machine for a numerical control linear guide rail. The precise composite molding grinding machine comprises a U-shaped base. The U-shaped base is provided with an embedded grinding workbench which is driven by a drive device and can horizontally move in the longitudinal direction. The embedded grinding workbench is provided with a magnetic clamp used for fixing the guide rail. A portal frame is arranged above the U-shaped base. A beam of the portal frame is provided with a first transverse drive mechanism and a second transverse drive mechanism. The first transverse drive mechanism is connected with a first vertical grinding head mechanism through a first vertical drive mechanism, and the second transverse drive mechanism is connected with a second vertical grinding head mechanism through a second vertical drive mechanism. A vertical bearing frame is arranged in front of the portal frame and provided with a third transverse drive mechanism. The third transverse drive mechanism is connected with a horizontal grinding head mechanism through a third vertical drive mechanism. Due to the fact that the first vertical grinding head mechanism, the second vertical grinding mechanism and the horizontal grinding head mechanism are used for grinding the two side faces and the installing bottom face of the guide rail at the same time, workpieces do not need to be clamped many times, the machining efficiency and the grinding precision can be greatly improved, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to a grinding machine, in particular to a linear guide grinding machine. Background technique [0002] In the production process of the linear guide rail, it is necessary to use a guide rail grinder to grind the two sides, the raceway surface and the installation bottom surface of the linear guide rail. In the prior art, most guide rail grinding machines use two grinding heads. Generally, after the bottom surface of the guide rail is ground, it is installed on the workbench, and then the two sides of the guide rail are processed. The overall length error and installation error of the machine tool directly affect the linear guide rail pair. At the same time, even if three grinding heads are used, affected by the structure of the machine tool, or the horizontal grinding head does not use an independent column, or the distance between the fixture surface of the linear guide rail and the guide rail surface of the worktable is relative...

In the prior art, most guide rail grinding machines use two grinding heads. Generally, after the bottom surface of the guide rail is ground, it is installed on the workbench, and then the two sides of the guide rail are processed. The overall length error and installation error of the machine tool directly affect the linear guide rail pair. At the same time, even if three grinding heads are used, affected by the structure of the machine tool, or the horizontal grinding head does not use an independent column, or the distance between the fixture surface of the linear guide rail and the guide rail surface of the worktable is relatively large, or the distance between the centers of the vertical and horizontal grinding heads is relatively large. Large (above 500 mm), the motion distortion accuracy of the machine tool table is also likely to affect the linear guide rail motion distortion accuracy
