Abstract

The invention discloses an XYZ axis three-direction precision compensation structure suitable for a precision handling mechanism, comprising an upper mounting plate and a lower mounting plate of the mechanism, a guide component and an elastic plunger are arranged on the upper mounting plate of the mechanism; the guide component is arranged on the mechanism At the four corners of the installation plate, elastic plungers are arranged symmetrically on the opposite edges of the upper installation plate of the mechanism, the bottom of the elastic plunger is connected to the lower installation plate of the mechanism, and the guide assembly is inserted into the lower installation plate of the mechanism; the guide assembly includes Guide sleeve and guide shaft, the guide sleeve is fixed on the upper installation plate of the mechanism, the guide shaft is in the guide sleeve and the bottom of the guide shaft is inserted into the lower installation plate of the mechanism, and is squeezed to the elastic plunger by the downward movement of the Z axis of the conveying mechanism The guide shaft and the guide sleeve can be separated, and a matching gap is formed between the separated guide shaft and the guide sleeve; the upper mounting plate of the mechanism is also provided with a top tightening screw. The invention realizes the three-direction precision compensation of the XYZ axis of the transport mechanism, and improves the transport success rate, the transport precision and the transport quality.

Description

technical field [0001] The invention belongs to the technical field of precision machine tool equipment components, and in particular relates to an XYZ axis three-direction precision compensation structure suitable for a precision handling mechanism. Background technique [0002] The handling mechanism of the precision CNC machine tool equipment controls the handling action through its own X-axis, Y-axis, and Z-axis. The X-axis, Y-axis, and Z-axis determine the handling accuracy of the handling mechanism; The cutting disc is transported to the cleaning module, and then transported to the turning drying module. The cutting process will cut a whole semi-finished product into several small semi-finished products. The suction cup of the hole sucks each small semi-finished workpiece and transports it to the next processing module; the side length of the workpiece handled by the handling mechanism is as small as about 2mm, and the diameter of the suction hole of the suction cup us...

Problems solved by technology

[0002] The handling mechanism of the precision CNC machining machine tool controls the handling action through its own X-axis, Y-axis, and Z-axis. The X-axis, Y-axis, and Z-axis determine the handling accuracy of the handling mechanism; The cutting disc is transported to the cleaning module, and then to the turning and drying module. During the cutting process, a whole piece of semi-finished product will be cut into several small semi-finished products. The suction cups of the hole respectively suck each small semi-finished workpiece to be transported to the next processing module; the side length of the workpiece transported by the transport mechanism is as small as about 2mm, and the diameter of the suction hole of the suction cup used for transportation is already close to the minimum workpiece side length. The handling position is abnormal, the position of the suction cup and the workpiece is deviated, and the vacuum is likely to leak in the misaligned suction hole, which will cause poor handling, affect the structural accuracy and strength, and even fail to transport; The solution to the problem of handling accuracy is to use high-precision screw to cooperate with the X-axis, Y-axis, and Z-axis of the handling mechanism. This method does not improve the accuracy well, and the cost is too high
