A control method for sponge cutting machine based on servo motor detection and fine-tuning of guide rail parallelism

Abstract

The invention relates to a control method based on servo motor detection and fine-tuning of the parallelism of guide rails for a sponge cutting machine, which uses the load value read by the computer to see whether the movement load difference of each axis increases by using the load value of the servo motor that tightens the knife belt and operates Whether the four guide rails are parallel, when it is detected that the four guide rails are not parallel, stop the machine, loosen the screws of the two outermost guide rails, and then lock the outermost two guide rails again; Loosen the screws of the guide rail, start the machine, the vibration box runs up and down, so that the load difference is basically consistent, run the vibration box a little, lock the screws, and cycle this action, and always lock the screws of the two inner guide rails. Tight, finally make the four guide rails adjusted parallel. The invention has the advantages of fixing the two outermost guide rails, and gradually adjusting the inner two guide rails by using the load value of the servo motor, finally ensuring the parallelism of the four guide rails.

Description

technical field [0001] The invention relates to a control method for detecting and fine-tuning the parallelism of guide rails based on a servo motor for a sponge cutting machine. Background technique [0002] At present, the oscillating knife sponge cutting machine is a large gantry workpiece that is difficult to process at one time and can ensure good parallelism because of the relatively large gantry frame and the large distance between the parallel spans of the guide rails. Once the workpiece is clamped twice, it is difficult to meet the parallelism requirements of the guide rails. If the guide rails are not parallel, it is easy to cause damage to the slider, the noise of the vibration box will increase, and the knife belt is easy to be broken. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a control method for sponge cutting machine based on servo motor detection and fine adjustment of the parallelism of gu...
