Description

Technical Field

[0001] The utility model relates to a rapid clamping and positioning device for a web inside a drum, belonging to the technical field of web installation auxiliary equipment. Background Art

[0002] With the continuous improvement of the mechanized harvesting rate of grain crops in my country and the continuous development trend of harvesting machinery and equipment towards large-scale, multi-functional and integrated directions, the production and manufacturing of large-scale harvesting machinery and equipment such as wheat harvesters also faces many challenges, especially the increasingly complex welding tooling links.

[0003] At present, an inner width plate needs to be added to the drum of a wheat harvester to improve the strength of the drum. During the installation of the inner width plate of the drum, a ruler is mostly used to measure the position of the inner width plate of the drum to ensure the verticality of the width plate. Specifically, the existing width plate is positioned inside the drum by using a ruler to measure the distance between the width plate and the end face of the drum to ensure the verticality of the width plate relative to the axis of the drum, and each measurement needs to be spot-fixed at the plug weld to ensure the correct size. However, relying on a ruler to measure and spot-fix is ​​laborious and time-consuming, has a low degree of automation, and poor positioning accuracy. Therefore, a quick clamping and positioning device for the inner width plate of the drum is needed. Utility Model Content
