Description

Technical Field

[0001] The invention relates to the technical field of positioning devices, and in particular to an anti-deformation positioning device for manufacturing a wind tower door frame. Background Art

[0002] At present, the competition in the wind tower industry is becoming increasingly fierce. The steel structure division's business orders present a situation of more projects and less batches. On-site customer representatives have higher and higher requirements for product quality, especially for the surface appearance quality of wind towers. Door cover is a building decoration term, which refers to the two door frames inside and outside the door, and is also directly called door frame. Its main function is to fix the door leaf and protect the corners and decorations. It is often used in the decoration process to protect the door from scratches, corrosion, damage, dirt, etc. The door frame of the wind tower is composed of two door frame vertical blocks, door frame upper horizontal blocks and door frame lower horizontal blocks. The welding quality and flatness of the door frame directly affect the sealing performance of the wind tower door frame and the aesthetic effect of the product. At present, there are many problems in the welding of door frames.

[0003] When welding the door frame of a wind tower, since the joint of the door frame needs to be welded up and down, in the current production device, the door frame is fixed in a fixed device, which is not convenient for adjusting the spacing between the door frame profiles. During the welding process, the joint of the door frame cannot be well positioned and fixed, resulting in a large error between the actual size of the door frame after production, which greatly reduces the practicality of the device.
