Abstract
The utility model discloses an orientation is preapred for an unfavorable turn of events to appear and is hanged down residual stress welding jig, including the anchor clamps platform, the slide at anchor clamps platform both ends is installed to two symmetries, and two symmetries are installed at the inboard screw rod of anchor clamps platform upper saddle, the clamp plate of two symmetry covers on the screw rod, two gyro wheels, two cams to and install the kingpin of intermediate position department on the anchor clamps platform, and the both ends of every clamp plate are connected with a gyro wheel and a cam respectively, and two cams are laminated with the slide of homonymy respectively. The utility model discloses a cam drives the gyro wheel and carries out the work piece clamp tightly, and the clamp is tight reliable, keeps a period after welding, treats the welded joint performance and becomes flexible the cam after basicly stable, removes the clamp plate, guarantees when utilizing rolling friction can realize controlling bottom plate deformation of welding angle that the weldment transversely freely is out of shape, reduces and welds the internal stress, realizes the one -way deformation function that prevents.
Description
Technical field
This utility model relates to a kind of weld jig, specifically a kind of orientation anti-deformation low residual stress weld jig, belongs to weld jig technical field.
Background technology
At present, T connector is when welding, and in order to prevent Welding Angular Deformation, many employing spot welding fix or Rigid Plates Under Compression is fixed.The rigidity staff cultivation of such method butt-welding fitting, it is impossible to realize the control of one direction welding deformation, though effectively controlling Welding Angular Deformation, but limiting cross-direction shrinkage deformation, being easily caused weld seam internal stress high, affecting joint performance.
Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides one orientation anti-deformation low residual stress weld jig, can control welding point Welding Angular Deformation, it is possible to ensure the free shrink that weldment is horizontal, reduce welding interior stress, it is achieved unidirectional anti-deformation function.
To achieve these goals, a kind of orientation anti-deformation low residual stress weld jig that this utility model uses, including jig platform, two slides being symmetrically mounted on jig platform two ends, two screw rods being symmetrically mounted on inside jig platform upper saddle, the pressing plate that two symmetries are enclosed within screw rod, two rollers, two cams, and it is arranged on the needle roller of middle position on jig platform, the two ends of each pressing plate are connected with a roller and a cam respectively, and two cams slide with homonymy respectively is fitted.
Preferably, described screw rod is telescopic structure.
Preferably, the two ends of described pressing plate are connected with roller, cam by the way of hinged.
Preferably, jig platform is laid the length of needle roller more than the distance between two rollers.
Compared with prior art, this utility model carries out Workpiece clamping by cam driven roller, reliable clamping, keep a period of time (time length is determined by mother metal) after welding terminates, loosen cam after joint performance to be welded is basicly stable, remove pressing plate, utilize rolling friction to ensure the laterally free deformation of weldment while being capable of controlling base plate Welding Angular Deformation, reduce welding interior stress, it is achieved unidirectional anti-deformation function.Overcome the rigidity staff cultivation that plain clamp produces, it is impossible to realize the defect of unidirectional constraint.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of orientation anti-deformation low residual stress weld jig, including jig platform 8, two slides 7 being symmetrically mounted on jig platform two ends, two screw rods 6 being symmetrically mounted on inside jig platform 8 upper saddle 7, the pressing plate 2 that two symmetries are enclosed within screw rod 6, two rollers 3, two cams 1, and it is arranged on the needle roller 5 of middle position on jig platform 8, the two ends of each pressing plate 2 are connected with a roller 3 and a cam 1 respectively, and two cams 1 slide 7 with homonymy respectively is fitted.Owing to using rotatable roller as hold-down mechanism, lower support uses needle roller support, and the while that clamp being reliable, rolling friction replaces sliding friction to ensure the laterally free contraction of workpiece.
Preferably, described screw rod 6 is telescopic structure.
Preferably, the two ends of described pressing plate 2 are connected with roller 3, cam 1 by the way of hinged.
Preferably, jig platform 8 is laid the length of needle roller 5 more than the distance between two rollers 3.
From said structure, this utility model carries out Workpiece clamping by cam driven roller, reliable clamping, keep a period of time (time length is determined by mother metal) after welding terminates, loosen cam after joint performance to be welded is basicly stable, remove pressing plate, utilize rolling friction to ensure the laterally free deformation of weldment while being capable of controlling base plate Welding Angular Deformation, reduce welding interior stress, it is achieved unidirectional anti-deformation function.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; on the premise of without departing from this utility model structure; some deformation and improvement can also be made; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.
