Description

Novel double pressing roller type face of weld levelling device

Technical field

The utility model belongs to welding tool for friction stir welding tack weld device, the butt weld for soldering part A kind of smoothing before welding, and in particular to novel double pressing roller type face of weld levelling device.

Background technique

Tradition mostly uses first when carrying out weld seam smoothing to long aluminum alloy thin profile material weldment using welding tooling by grasping Author smooths weld seam with leveling hammer, then the clamping card orchid loaded onto of recruitment carries out weldment longitudinally fixed, or is welding Large-scale weight fixed mode is installed in tooling.However, such smoothing mode can there are problems that during actually smoothing: (1) with leveling hammer to weld seam carry out manually smooth again with clamp card orchid workpiece is fixed after, smooth after weld seam still occur Deformation, must carry out secondary smoothing；(2) since aluminium alloy sheet is long size profile, smoothing time used time is long by hand, work effect Rate is low；(3) smoothing is to be had been manually done by operator with leveling hammer before being welded due to weld seam, is smoothing to be judged with eyes whether It is smooth, there is certain human factor.

It carries out smoothing the existing above problem to solve conventionally employed leveling hammer, 204584538 U of Chinese patent CN is provided Positioning device is smoothed before a kind of stir friction welding seam welding, which in such a way that pneumatic pinch roller steps up automatically carries out school Flat, smooth welded seam after smoothing substantially increases labor efficiency, reduces costs.However, finding such mode still by practice There are problems, it may be assumed that since the top that the position of weld seam smoothing wheel is placed exactly in face of weld (is pressed in two pieces of aluminum profile thin plate docking Commissure), so weld seam smoothing wheel impurity or grease will be retained on face of weld when not cleaning out, weld These impurity or grease will be stirred to inside weld seam and be gone in termination process, influence weldquality.

Summary of the invention

The purpose of this utility model is to provide a kind of novel double pressing roller type face of weld levelling devices, to solve existing single pressure Wheel levelling device is easy the technical issues of there is attachment impurity or grease, influencing weldquality when being smoothed.

To achieve the above object, the utility model adopts the following technical scheme that realization:

Novel double pressing roller type face of weld levelling device, comprising: station, two workpiece positioning groups being mounted on station Part, the pressing device being mounted on agitating friction weldering welding equipment main shaft；Wherein, the workpiece positioning component includes being fixed on behaviour Make platform two sides the first support base and the second support base, be fixed among station third support base, be fixed on the first support The supporting block in seat outside, the first profiling cushion block being fixed on the inside of the first support base, the profiling limit being fixed on the inside of supporting block Block, the support plate being fixed on the second support base, is fixed on the supporting plate the first active grab being mounted on the outside of supporting block First profiling cushion block is mounted on support close to clamping cylinder, the close clamping cylinder that the first profiling cushion block is mounted in support plate The second active grab on plate, the second profiling cushion block being fixed on third support base；The pressing device includes being fixed on master Telescopic cylinder on axis, pinch roller support, the connecting shaft, two ball bearings, retaining rings being connect with the telescopic end of telescopic cylinder；It is described The end of pinch roller support is U-shaped structure, and connecting shaft, which is worn, to be fixed in pinch roller support；The inner ring of ball bearing described in two is equal It is fixed in connecting shaft, retaining ring is mounted in connecting shaft and the centre of two ball bearings is arranged in；Two ball bearings Outer ring be arranged in workpiece docking weld seam both sides.

As the preferred of the utility model, it is also equipped with four-supporting in the two sides of the third support base, described Locating piece is installed on four-supporting, is able to carry out accurate positionin when aluminum profile thin plate convenient for placing.

As the preferred of the utility model, it is machined on first support base, the second support base, third support base Lightening hole.

The advantages of the utility model and good effect are: levelling device structure provided by the utility model is simple, user Just, solving the problem of that single pinch roller levelling device has attachment impurity or grease at present influences weldquality.Using the utility model Device, weld seam has directly carried out weld seam smoothing in the welding process, while guaranteeing weldquality, shortens weld seam and welds preceding school Between usually or do not have to smoothing before weldering, substantially reduces the working time, improve labor efficiency, reduce costs.
