An automatic loading and unloading device and method applied to a five-axis machine tool

Abstract

The invention discloses an automatic loading and unloading device applied to a five-axis machine tool in the technical field of machine tool loading and unloading. Fixture threaded rods run through both sides of the top surface, and the fixture threaded rods are threadedly connected with the fixture seat, and both sides of the top surface of the fixture seat are also provided with fixture plates. Rod screw connection; the invention can make the blank parts move from the arc track to the top of the fixture seat first, and then move vertically to the loading place of the fixture seat when the material is transferred and loaded. The position of the blank parts is accurate and there will be no error .

Description

technical field [0001] The invention relates to the technical field of loading and unloading of machine tools, in particular to an automatic loading and unloading device and method applied to five-axis machine tools. Background technique [0002] At present, the loading and unloading of CNC machine tools on the production lines of many domestic factories is still done manually, which is labor-intensive and low in production efficiency; the manipulator is an automatic device used in the automated production process to grab and move workpieces, which can replace humans. Dangerous, repetitive and boring work, reduce labor intensity and improve labor productivity. [0003] At present, the loading and unloading devices can basically include intelligent manipulators, truss loading and unloading devices, and track-type loading and unloading devices. Among them, the intelligent manipulator completes the automatic loading and unloading of the workpiece through a large number of smart...

[0002] At present, the loading and unloading of CNC machine tools on the production lines of many domestic factories is still done manually, which is labor-intensive and low in production efficiency; the manipulator is an automatic device used in the automated production process to grab and move workpieces, which can replace humans. Dangerous, repetitive and boring work, reduce labor intensity and improve labor productivity

[0003] At present, the loading and unloading devices can basically include intelligent manipulators, truss loading and unloading devices, and track-type loading and unloading devices. Among them, the intelligent manipulator completes the automatic loading and unloading of the workpiece through a large number of smart chip instructions. The cost of the intelligent manipulator is high. Maintenance The cost is high and it is difficult to apply; secondly, the height and length of the truss loading and unloading device and the movable stroke of the robot arm are generally tailored according to the width and height of the machine tool shape and the structural size of the machine tool. This characteristic of the truss loading and unloading device leads to its Only suitable for one kind of machine tool or suitable for machine tools with similar external dimensions and roughly the same structure

The biggest disadvantage of the truss loading and unloading device is its poor versatility; a small number of existing track-type loading and unloading devices need to extend the track to the inside of the machine tool when using it, and then place the blank on the fixture seat. Although this method solves the The problem of manual handling of parts, because the shape and center of gravity of parts and blanks is not easy to control, and the track needs to be advanced and removed at the same time, so that the track needs to move smoothly, making the track advance slower, thus prolonging the up and down to a certain extent. material time
