Problems solved by technology

At present, a kind of gear shaving or gear honing machine is used for grinding the gear surface. Using the generating principle, the end of the grinding wheel is ground point by point, and the processing efficiency is very slow; another example, if the surface after wire cutting is not smooth enough , it must be cut many times, not only the efficiency is not high but also the final finish is greatly limited

Embodiment Construction

[0018] as attached figure 1 As shown, a CNC electric spark surface grinder, the bed (1) is fixedly connected with the column (2), and the protruding part of the column (2) forms a detachable rotational connection with the grinding head (4). The detachable purpose In order to facilitate the replacement of the grinding head, clamping methods such as spring clamps can be used. The grinding head (4) is driven to rotate by the rotary drive device (3); the upper and lower sides of the carriage (11) are provided with mutually perpendicular guide rails, and the guide rails below it It forms a sliding connection with the bed (1), and the upper guide rail forms a sliding connection with the worktable (9). The horizontal drive device (12) installed on the bed (1) drives the carriage to drive the workbench to move left and right. The longitudinal driving device (10) on the carriage (11) drives the workbench (9) to move back and forth; the workbench (9) is provided with an insulated workpi...

Abstract

The digitally controlled curved electric spark grinder has bed, upright with stretched part to constitute rotating connection with grinding head, driver to rotate the grinding head, trailing bar with vertical guide rails including guide rail connected to the bed below the trailing bar and guide rail on connected to the bench on the trailing bar, transverse driver on the bed for the trailing bar to drive the bench left and right, longitudinal driver on the trailing bar to drive the bench back and forth, insulated workpiece holder set on the bench, pulse power source to output electric pulse across the X electrode connected to the workpiece and the Y electrode connected to the grinding head, work fluid supplying device, and control system to control the motion of the parts. The present invention can perform programmed electric spark grinding of various kinds of curved surface, and has high precision, high speed, high surface quality and low cost.

Description

technical field [0001] The invention relates to an electric discharge machine tool, in particular to a numerically controlled electric discharge machine tool for automatic electric discharge grinding of curved surfaces. Background technique [0002] It is very difficult to process parts with curved surfaces, such as gears and cams, with general-purpose grinding machines, because general-purpose grinding machines can only grind flat surfaces and regular inner and outer circular surfaces. At present, a kind of gear shaving or gear honing machine is used for grinding the gear surface. Using the generating principle, the end of the grinding wheel is ground point by point, and the processing efficiency is very slow; another example, if the surface after wire cutting is not smooth enough , it must be cut many times, not only the efficiency is not high but also the final finish is greatly limited. Contents of the invention [0003] The technical problem to be solved by the prese...
