Description

Technical Field

[0001] This invention relates to the field of exhaust fan processing technology, and in particular to an exhaust fan housing welding processing device. Background Technology

[0002] Exhaust fans are core equipment for ventilation in industrial and civil buildings. Their outer shells are mostly made of metal sheets that are stamped, spliced, and welded together. The welding quality directly determines the structural strength, sealing performance, and service life of the exhaust fan. Traditional exhaust fan shell welding mainly relies on manual hand-held welding torches, which has problems such as high labor intensity, low welding efficiency, weld quality that is greatly affected by the operator's skill level, and poor consistency. Moreover, the arc light and high-temperature fumes generated during the welding process can seriously endanger the health of the operators, making it difficult to meet the needs of large-scale, standardized industrial production.

[0003] Chinese document CN203541866U discloses an automatic welding device for fan housings, comprising a frame, a welding table mounted on the frame, a gear rack connected to the bottom of the welding table, and notches at the four corners of the welding table. A welding frame is mounted on the frame, and a welding gun is mounted on the top of the welding frame, with the welding end of the welding gun corresponding to the notch. A motor is mounted on the frame, and the motor is connected to a speed-changing steering gear. The speed-changing steering gear is connected to a gear via a rotating shaft, and the gear meshes with the gear rack. This invention enables simultaneous welding of all four corners of a fan housing in one operation, achieving mechanized welding and improving welding accuracy and quality.

[0004] The aforementioned automatic welding equipment for fan housings has a fixed welding mechanism in practical applications. It can only complete straight weld seams in a plane by moving the welding table linearly, lacking multi-dimensional spatial angle adjustment capabilities. It cannot cover complex curved surface weld seams such as arc corners, bends, and flange connection surfaces of the exhaust fan housing, resulting in the need for manual welding of weld seams in special locations. The overall production efficiency is only slightly improved. Furthermore, the single-station design requires the machine to be stopped and the workpiece changed directly below the welding head after a set of workpieces is welded. This not only poses safety hazards such as accidental contact with the welding torch and workpiece falling, but also results in the equipment being completely idle during the material change process, leading to poor equipment utilization. Summary of the Invention

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a welding processing device for exhaust fan housings that can solve the problems of lack of multi-dimensional spatial angle adjustment capability, inability to cover complex curved surface welds such as arc corners, corners, and flange connection surfaces of exhaust fan housings, and the use of a single-station design.

[0018] (2) The exhaust fan housing welding processing device can drive the rotation of the material support plate to realize the alternating operation of the two workstations. After welding one set of workpieces, it can directly rotate to switch to another set of pre-installed workpieces without the need to change materials under the welding head. This solves the safety hazards such as falling objects from height and accidental injury from welding guns that exist when changing materials in traditional single-station devices, and ensures the personal safety of operators. Moreover, the material changing and welding processes are carried out simultaneously, reducing the material changing time by more than half, eliminating the equipment standby time, significantly improving the continuous production efficiency, and adapting to the needs of mass production line production.

[0019] (3) The exhaust fan housing welding processing device can quickly adjust the clamping distance between the front and rear clamping plates.

[0036] Working principle: Place the exhaust fan housing to be welded on the material support base plate 2. Control motor 12 to drive the rotation of the bidirectional threaded rod 7, and then drive the convex slider 8 to move. Adjust the clamping distance of the two sets of clamping plates 9 to clamp the exhaust fan housing. Control cylinder 17 to push the U-shaped plate 15 to move back and forth. Then control electric push rod 20 to drive the horizontal plate 18 to move left and right. Then control hydraulic rod 24 to drive the lifting plate 23 to move up and down. Then adjust the angle of welding head 6. Then control welding head 6 to perform welding. When one set of exhaust fan housings below welding head 6 is processed, control motor 44 to drive the rotation of transmission worm gear 43. After the transmission worm gear 43 meshes with the transmission worm wheel 41, it drives the mounting column 3 to rotate, which in turn drives the rotation of the material support base plate 2 and places another set of pre-installed exhaust fan housings below welding head 6.
