A fixing mechanism for welding of fan air guide tube

Abstract

The invention discloses a fixing mechanism for fan air duct welding, which comprises a frame fixing seat, an upper support frame is fixed on the top surface of the top plate of the frame fixing seat, and the frame directly below the top plate of the upper support frame is fixed The top surface of the top plate of the seat is fixed with a lower installation fixed plate, and the middle part of the top surface of the lower installation fixed plate is fixed with a tapered positioning part with a larger diameter at the lower part and a smaller diameter at the upper part. The tapered sleeve to be processed is inserted into the tapered positioning part. The inner side wall of the tapered sleeve to be processed is close to the outer side wall of the tapered positioning part; the middle part of the top surface of the top plate of the upper support frame is fixed with a telescopic cylinder, and the push rod of the telescopic cylinder passes through the bottom surface of the top plate of the upper support frame and A lifting main board is fixed, and vertical plates are fixed on the left and right sides of the bottom surface of the lifting main board. The invention can automatically press and fix the sleeve to be welded and the tapered sleeve to be processed, which is convenient for manual welding. It only needs one person to operate, which greatly reduces the amount of manual labor and improves production efficiency.

Description

technical field [0001] The invention relates to the technical field of fan processing equipment, and more specifically relates to a fixing mechanism for welding of a fan guide tube. Background technique [0002] When the existing fan is installed, it is generally necessary to install an air guide to realize the connection between it and the air duct flow pipe, and the diameter of some air duct flow pipes is different from the diameter of the connecting pipe of the air outlet or air inlet of the fan. Therefore, it is necessary to install a variable-diameter air guide, and the existing variable-diameter air guide is generally a cylindrical sleeve welded to one end of the conical tube connected to the fan, the cylindrical sleeve is fixedly connected to the fan, and the other end of the conical tube is connected to the fan. pipe flow pipe; [0003] The welding of the tapered cylinder and the cylindrical sleeve is generally manual welding, which requires manual support and splic...

AI Technical Summary

Problems solved by technology

[0003] The welding of the conical cylinder and the cylindrical sleeve is generally manual welding, which requires manual support and splicing of the two, and then welding, which is inefficient and requires two people to operate, which requires a large amount of manual labor.
