Description

Technical Field

[0001] This utility model relates to the field of diesel engine welding technology, and in particular to an auxiliary workbench for welding diesel engine camshaft housings. Background Technology

[0002] Welding auxiliary workbenches are typically used in the welding of diesel engine camshaft housings, and these workbenches generate a large amount of fumes during the welding process. These fumes mainly consist of metal vapors and decomposition products of the welding materials.

[0003] Traditional auxiliary workbenches for welding diesel engine camshaft housings often focus on workpiece positioning and fixation, lacking effective design for welding fume treatment. Most workbenches typically lack dedicated fume collection and purification devices, or are only equipped with simple ventilation equipment. During actual welding operations, fumes permeate the work area, not only interfering with the operator's vision and affecting welding accuracy, but also posing hazards to the operator's respiratory system. Prolonged exposure to such an environment can easily lead to occupational health problems. Utility Model Content

The rotation of the double-headed screw 27 drives the cross plate 28 to move. The movement of the cross plate 28 drives the clamping plate 30 to clamp and fix the diesel engine camshaft housing. Then, the second motor 25 drives the rotating rod 24 to rotate. The rotation of the rotating rod 24 drives the connecting plate 22 to rotate. The rotation of the connecting plate 22 drives the arc plate 23 to rotate along with the rotating rod 24, which can adjust the angle of the diesel engine camshaft housing. Then, the electric push rod... The lifting plate 9 is lowered by the first motor 20, which in turn lowers the welding head 14.
