Welding bed for automatically detecting welding seams

Abstract

The invention discloses a welding bed for automatically detecting welding seams. The welding bed comprises a workbench, a slide carriage, pressure plates, a stepper motor, a welding head, a welding head fixture, a linear charge coupled device (CCD), a computer, a motor controller and the like, wherein the slide carriage is connected with the workbench through a screw rod on the lower part of the workbench, the screw rod is connected with the stepper motor simultaneously, and the stepper motor is used for controlling the slide carriage to transversely move; the pressure plates are arranged at four corners of the slide carriage respectively and are used for fastening workpieces put on the slide carriage; the welding head fixture is connected with the workbench through a screw rod on the upper part of the workbench; the welding head is fixed in front of the welding head fixture; the stepper motor drives the screw rod to rotate so as to ensure that the welding head moves in a longitudinal direction; the linear CCD is fixed above the workbench and is used for shooting images of the workpieces and transmitting the acquired images to the computer for analysis; the computer controls the stepper motor to move according to an analysis result so as to ensure that the welding head moves along the welding seams; and a moving speed can be controlled through the computer so as to accurately control a welding speed and a welding path.

Description

technical field [0001] The invention relates to a welding bed for automatic welding seam detection, in particular to a welding bed which detects the welding seam by a computer and precisely controls the movement of the welding bed slide plate and the welding head to achieve precise welding. Background technique [0002] In industrial production or teaching research and experiments, it is often necessary to perform precision welding on cracks or gaps on some workpieces. The current welding bed is basically operated manually by humans, or controlled by programming programs. Manual operation is not only cumbersome, but also has low accuracy and heavy workload. Although the accuracy can be improved by writing programs, the requirements for operators are relatively high. They must understand the professional knowledge of welding bed and welding. Not every operator They are all competent, and sometimes a simple welding task requires writing a very complicated program, which is a w...

[0002] In industrial production or teaching research and experiments, it is often necessary to perform precision welding on cracks or gaps on some workpieces. The current welding bed is basically operated manually by humans, or controlled by programming programs. Manual operation is not only cumbersome, but also has low accuracy and heavy workload. Although the accuracy can be improved by writing programs, the requirements for operators are relatively high. They must understand the professional knowledge of welding bed and welding. Not every operator They are all competent, and sometimes a simple welding task requires writing a very complicated program, which is a waste of time and may not achieve the desired effect. Due to the lack of this aspect, there are often large errors in the welding in the experiment, affecting The accuracy of the final experimental results is often caused by such reasons in industrial production.
