Calibration device for welding frame

Abstract

The invention discloses a calibration device for a welding frame. The calibration device includes a rack platform in butt joint with an external transmission mechanism, a liftable roller transmissionmechanism is arranged below the rack platform, rises to continuously transmit the welding frame transmitted from the external transmission mechanism to the rack platform and falls to land the weldingframe to the rack platform; the rack platform is provided with a positioning and fixing mechanism for adjusting and fixing the position of the landed welding frame; and the rack platform is provided with one or more mobile calibration mechanisms for calibrating the welding frame, and the mobile calibration mechanisms can transversely move on the side edge of the rack platform in the transmission direction of the rack platform so that calibration work of the different positions of the fixed welding frame can be achieved. The calibration device has the advantages of the high automation and intelligence degree, the high calibration efficiency and the high calibration accuracy, greatly reducing the intensity and danger of manual operation and greatly improving product quality.

Description

technical field [0001] The invention mainly relates to the field of automatic welding equipment, in particular to a calibration device for welding frames. Background technique [0002] In existing production, it is necessary to weld a large frame piece, which is formed by welding a plurality of material parts. Because of the heat generated during the welding process and the change of internal force, there will be a large deformation after forming, so it is necessary to detect and correct the shape after the welding is completed. The traditional correcting method is to heat the weldment by flame, so that the weldment is locally heated and then cooled rapidly, resulting in changes in internal stress. This method is more dependent on manual operation skills and is not universal. There are the following technical problems: [0003] One is the low efficiency of school work. Due to the need to manually hold multiple tools such as flame guns and calibration tooling to heat and ca...

AI Technical Summary

Problems solved by technology

[0003] First, the efficiency of school work is low

Due to the need to manually hold multiple tools such as flame guns and calibration tooling to heat and calibrate the welding points one by one, and then use water cooling to cool them down, and there are many welding points on large frame parts, which may require calibration There are too many points, which leads to the extremely low efficiency of the school type work, which seriously affects the follow-up work

[0004] The second is that the school type is not uniform and the accuracy is poor

Since most of the existing calibration methods use local heating of the workpiece and then water cooling to cause local stress changes and deformation of the workpiece, this method relies on the worker's operating skills and experience, resulting in manual calibration. The methods and experience are not uniform, which leads to the lack of uniformity in the calibration results between different batches of frame parts or between different solder joints of the same frame product, and the accuracy of the calibration is poor, which ultimately affects Product quality and strength

[0005] The third is that the labor intensity of the school type is high, and it is easy to forget a certain point of the school type

Due to manual calibration, this leads to high labor intensity; and due to the large number of welding points on large frame parts, it often occurs that a certain solder joint forgets to calibrate or skips calibration, which seriously affects the quality and strength of the product.

[0006] Fourth, the degree of automation and intelligence is low

The existing calibration operation is not only a manual operation of the calibration itself, but also manual loading before calibration and manual unloading after calibration, so that the calibration cannot cooperate with other automation equipment (for example, it cannot be connected to automatic loading Material feeding and feeding transmission equipment, can not be connected to the automatic detection equipment before the calibration) used, resulting in the calibration can not meet the needs of high-efficiency, automated operations, can not form an automated system operation

[0007] Fifth, the school type is dangerous

Since it is necessary to manually hold multiple tools such as flame guns and calibration tooling to heat and calibrate the welding points one by one, and then use water cooling to cool them, this makes the job site have high temperature, flames, cooling water, and cooling water. Dangerous components such as steam are not only prone to misuse by employees, but also cause potential safety hazards on site
