Grinding machine tool for dovetail guide rail

Abstract

The invention discloses a grinding machine tool for a dovetail guide rail. The grinding machine tool for the dovetail guide rail comprises a portal frame, a workbench, a machine tool guide rail and a base. A driving assembly frame is transversely fixed to the portal frame and provided with a grinding wheel, two driving mechanisms which are capable of moving transversely and longitudinally are arranged on the left side and the right side of the front face of the driving assembly frame, the grinding wheel can rotate on the driving mechanisms, the driving mode of the workbench is the hydraulic driving mode, the workbench comprises two layers, the bottom face and the side faces of the machine tool guide rail are all fixed to the base, the side faces of the machine tool guide rail are covered with covering plates, the contact faces between the covering plates and the side faces of the U-shaped ends of the base and the contact faces between the covering plates and the machine tool guide rail are provided with lubricating oil grooves, and through lubricating oil grooves are formed in the top of the guide rail face of the machine tool guide rail. After the scheme is adopted, the inclined faces of a V-shaped groove of the dovetail guide rail can be ground fully, the precision of ground products is higher, the driving stability of the workbench of the grinding machine tool can be guaranteed, and the service life of the machine tool is longer.

Description

technical field [0001] The invention relates to a machine tool, especially a machine tool for grinding dovetail guide rails. Background technique [0002] With the rapid development of the domestic machinery manufacturing industry, various types of grinding machines are gradually increasing, but there are few professional grinders used for grinding the dovetail guide rails of machine tools. Dovetail guide rails, also called V-shaped guide rails, require grinding due to their structural requirements. V-shaped groove, when the traditional grinding machine grinds the V-shaped groove, it uses a grinding wheel with a V-shaped edge to grind vertically. The disadvantage of this grinding method is that when the grinding machine adjusts the grinding stroke in the longitudinal direction, most of the grinding The force is concentrated on the plane of the V-shaped guide rail, that is, the so-called end face grinding.

[0002] With the rapid development of the domestic machinery manufacturing industry, various types of grinding machines are gradually increasing, but there are few professional grinders used for grinding the dovetail guide rails of machine tools. Dovetail guide rails, also called V-shaped guide rails, require grinding due to their structural requirements. V-shaped groove, when the traditional grinding machine grinds the V-shaped groove, it uses a grinding wheel with a V-shaped edge to grind vertically. The disadvantage of this grinding method is that when the grinding machine adjusts the grinding stroke in the longitudinal direction, most of the grinding The force is concentrated on the plane of the V-shaped guide rail, that is, the so-called end face grinding. Since the pressure of the grinding machine is concentrated on the end face, the beveled edge of the V-shaped guide rail is not sufficiently ground during grinding, which leads to the V-shaped guide rail in the grinding process. The transmission precision on the machine tool affects the quality of the entire machine tool

[0003] In addition, most of the worktable driving mechanisms of traditional surface grinders are chain drives. Due to their simple structure, they are generally used to process some end faces with low precision requirements. However, if some parts to be processed require high precision , because the stability of the chain transmission is not very good, and the transmission gap is large, it is easy to produce errors during grinding, which affects the precision
