Description
Technical field
The utility model relates to a kind of welder, particularly a kind of device that can eliminate stress in welding.
Background technology
Drive axle is the light-duty vehicle important spare part, adopts the welding method manufacturing more.Drive axle housing residual stress after the welding is bigger, causes the vehicle bridge distortion big, and axle housing antifatigue degree is low, in comparatively operation of following time of condition of severe of working environment, has the small part automotive axle crackle can occur, to the bigger harm of safety traffic formation of automobile.The production of tradition axle housing mainly adopts the heat aging mode to eliminate welding stress.This arts demand is built large-scale annealing furnace, adopts the heating of electricity or coal, the equipment investment height, and energy resource consumption is big, the cost height, environmental pollution is serious, the workman works under hard conditions.
Vibration Welding is a new welding procedure that grows up on the oscillating aging basis, and it is to apply periodic exciting external force to welding in normal candle termination process, makes the weldment vibration, thereby reaches the reduction welding residual stress, improves welding quality.But be in the periodically following time of effect of exciting external force when welding, the concentricity of drive axle will be affected, thereby influences the bearing capacity of automobile
Summary of the invention
The purpose of this utility model is intended to overcome the defective of prior art, and a kind of scientific and reasonable for structure, convenient welding is provided, the concentricity height, and stress is eliminated tangible vibration welding device.
Vibration welding device described in the utility model, comprise base, frame, vibrating device, anchor clamps and drive unit, frame is fixedly connected on the base, the two ends of frame are connected with anchor clamps respectively, one of them anchor clamps is connected with axle by bearing, vibrating device is connected with axle by the vibration connecting plate, and another anchor clamps are connected with drive unit by bearing, and the central point of two anchor clamps is positioned at same axial line.
Described anchor clamps are that draw-in groove is connected by the base of anchor clamps with frame,
Described drive unit is a motor.Motor is the 1-2 platform.When motor was 2, a motor was connected with anchor clamps, and another motor is connected with an end of pull bar, and the other end of pull bar is connected with soldering set.
Described drive unit is connected with frequency converter.
The periodicity amplitude of described vibrating device is between 0.2-0.06mm.
Vibration welding device described in the utility model, the central point of two anchor clamps is positioned on the same axial line, guaranteed weldment in welding process, the center of circle of weldment is positioned on the same axial line all the time, has guaranteed that weldment has higher concentricity, on the folder of one side of welding, connect vibrating device, give weldment with periodic vibration, amplitude makes weldment be in inferior vibrational state between 0.2-0.06mm, thereby reach the reduction welding residual stress, improve the purpose of weldment quality.Adopt metallographic degree sample to light up to stitch near the residual stress measuring point and get cross-sectional view, the analysis of metallograph can obviously be observed vibration to the welding influence of Joint.The metallographic structure of weld seam when amplitude is 0.06mm, 0.1mm, 0.2mm is 0 o'clock with respect to amplitude, and crystal grain diminishes, and column crystal trend dies down, and when amplitude is 0.2mm, is equiax crystal substantially; And the acicular ferrite or the granular bainite that are distributed on the crystal boundary diminish, and Widmannstatten structure also obviously reduces, and when amplitude was 0.2mm, acicular ferrite or granular bainite and Widmannstatten structure disappeared substantially.Testing identity, when using vibration welding device described in the utility model to weld, stress disappears substantially, has reached good welding effect.The utility model can adopt 1-2 platform motor-driven according to actual needs, in the time of need doing the ring-type welding to weldment, open a motor, convert electrical energy into rotating mechanical energy, drive the anchor clamps that are connected with motor and rotate, can realize welding or manual welding automatically.The staff only need hold soldering set, and soldering set is aimed at weld can finish welding, and need not mobile soldering set, improved the flatness and the precision of welding.When needs are done the straight line welding to weldment, open another motor, this motor converts electrical energy into straight-line mechanical energy, drive the pull bar moving linearly that is connected with motor, on pull bar, connect soldering set,, can realize the straight line welding as welding gun etc., operating personnel also only need welding gun and welding position are adjusted to relative position, can realize the straight line welding.In welding, do not reduce welding quality because of artificial factor, the staff only needs that also soldering set is aimed at weld and also promptly finishes the work, the staff's is easy to operate, and do not reduce welding quality in the welding because of artificial mobile factor, also can regulate the speed that vibration frequency and anchor clamps rotation, straight line move simultaneously according to the actual conditions that welding the time eliminates stress, the utility model is scientific and reasonable for structure, and is easy to operate, also can effectively eliminate stress when improving welding quality.
