Guide wheel lifting device for wire cutting machine

Abstract

The invention relates to a guide wheel lifting device for a wire cutting machine, which comprises a guide wheel, a guide wheel shaft and a guide wheel supporting frame, wherein the inner side of the guide wheel supporting frame is provided with a sliding slot which is connected with the guide wheel shaft in a sliding fit manner; the guide wheel supporting frame is fixed on the wire cutting machine by two connection rods. The guide wheel lifting device is simple and compact in structure, reasonable in design, convenient to adjust, and high in adjustment accuracy; as a plurality of U-shaped wire slots are formed, wires with small wire diameters, caused by wire loss, at the wire outlet end can be compensated effectively.

Description

technical field [0001] The invention relates to the field of wire cutting machine components, in particular to a wire cutting machine guide wheel lifting device with a simple and compact structure. Background technique [0002] The wire cutting machine tool is mainly composed of three parts: the main engine, the high frequency power supply and the controller. The main engine is composed of bed, coordinate table, wire storage drum, thread rack, working fluid tank and accessories. The molybdenum wire used for processing is wound on the wire storage drum, and the workpiece is placed on the fixture of the workbench and fixed with pressure plate screws. When the console sends out a signal to output pulses, the stepper motor rotates according to the signal, and the worktable is driven by the transmission gear and the screw nut pair to achieve the purpose of cutting geometric figures such as straight lines and arcs. [0003] In order to ensure the cutting quality of the wire cutt...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure the cutting quality of the wire cutting machine, the distance between the upper wire arm guide wheel of the wire cutting machine and the processed workpiece must be adjusted, and at the same time, the wire connecting the guide wheel is required to be perpendicular to the workpiece surface. In the prior art, the upper wire of the wire cutting machine The lifting device of the arm guide wheel is composed of a column, an upper wire arm, and a lower wire arm. The adjustment of the distance between the upper wire arm guide wheel and the workpiece is that the upper wire arm is driven up and down by the screw drive in the guide groove of the column. Its shortcomings The reason is that the pulling accuracy is poor and the operation is cumbersome, and the structure is complex and not compact
