A workpiece positioning device for horizontal CNC machine tools based on the principle of magnetic traction

Abstract

The invention discloses a workpiece positioning device for a horizontal numerically controlled machine tool based on the principle of magnetic traction. The structure includes a protective cover, a control panel, an inspection door, a main machine, a storage drawer, a fixed bracket, and a processing platform. The storage drawer is installed in an embedded manner. In the middle of the front end of the main unit, the main unit is fastened and connected with the fixing bracket. In the present invention, after the workpiece is placed on the processing platform, its two ends are positioned by the side positioning mechanism. The traction mechanism and the cutting spindle move synchronously, and the cutting point is reserved. When the traction mechanism moves, the linkage assembly at the bottom of the workpiece is moved by its magnetic force. Traction, and then can support and fix the lower surface of the tool cabinet in real time, and can ensure that the processing area surrounded by the traction mechanism and the linkage components achieves a fixed effect, so that the cutting spindle can be processed under stable conditions, which improves the processing quality and reduces the Difficulty of operation.

Description

technical field [0001] The invention relates to the field of laser cutting, in particular to a workpiece positioning device for a horizontal numerically controlled machine tool based on the principle of magnetic traction. Background technique [0002] CNC machine tool is a device that converts computer simulation data and finally realizes synchronous processing through the PLC system. Horizontal CNC machine tools are small in size among various CNC equipment, and are generally used for processing various plate-shaped workpieces. Cutting can also be applied to micro-engraving various small and exquisite workpieces, which belongs to high-precision CNC equipment. There are such problems in the use of existing technologies on the market: [0003] When the horizontal machine tool in the current technology is processing a large plate-shaped workpiece, the staff will fix it by glue or negative pressure adsorption because the plate-shaped workpiece has a certain amount of deformati...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a workpiece positioning device for a horizontal CNC machine tool based on the principle of magnetic traction, so as to solve the problem that the horizontal machine tool in the prior art processes a plate-shaped workpiece with a larger area due to the plate The workpiece has a certain amount of deformation, and the staff will fix it by glue or negative pressure adsorption. However, in order to prevent the glue from failing, liquid cooling cannot be performed. If the traditional mechanical fixation is used, all workpiece areas cannot be uniformly fixed at the same time, resulting in processing During the process, some points of the workpiece oscillate, which leads to unclear processed lines, which increases the difficulty of processing and needs to be optimized.
