Wire cutting machine

Abstract

The invention relates to the field of cutting equipment, in particular to a wire cutting machine. The wire cutting machine comprises a workbench, a sliding device, a clamping device and an adjusting device, the clamping device comprises a supporting frame and a first bearing block, and the first bearing block is rotationally connected with the supporting frame; the adjusting device comprises a bearing mechanism, a lifting mechanism and a second driving mechanism; the lifting mechanism comprises a supporting plate, a lifting plate, a turbine and a rack; the supporting plate is fixed to the workbench, and a sliding rod is in sliding fit with the supporting plate; the sliding rod penetrates through one end of a sliding groove to be rotationally connected with the turbine, the rack is fixed tothe supporting plate, the turbine is meshed with the rack, and the second driving mechanism is used for driving the turbine to rotate; and the bearing mechanism comprises a bearing frame and a connecting piece, one end of the first bearing block is rotationally connected with the bearing frame, one end of the connecting piece is fixedly connected with the bearing frame, and the other end of the connecting piece is in sliding fit with a fourth dovetail groove. According to the wire cutting machine, workpieces can be prevented from shaking in the workpiece machining process of the wire cuttingmachine.

Description

technical field [0001] The present application relates to the field of cutting equipment, in particular to a wire cutting machine. Background technique [0002] The wire cutting machine is mainly composed of three parts: machine tool, numerical control system and high frequency power supply. The numerical control system is composed of a single-chip microcomputer, a keyboard, and a frequency conversion detection system. It has the main functions of gap compensation, linear interpolation, circular interpolation, and automatic processing of broken wires. It can cut materials, such as high-strength, high-toughness, high-hardness, high-brittleness, magnetic materials, and precision small and complex-shaped parts. Wire cutting technology and wire cutting machine tools are being widely used in all walks of life. [0003] In the related art, the Chinese patent whose authorization notification number is CN208033855U discloses a wire cutting machine, comprising: a machine base; a be...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor found the following defects in the process of working: the abutment shaft is driven by the cylinder to expand and contract, so that the ball assembled on the top of the output shaft slides in the dovetail groove on the lower surface of the bearing plate , so as to realize the adjustment of the inclination angle of the bearing plate. The balls only have an upward bearing effect on the bearing plate, but they do not realize the fixing effect on the bearing plate. When the wire cutting machine is processing the workpiece, the bearing plate is prone to shaking
