Abstract
The utility model discloses a pneumatic welding clamp, which comprises a clamp base, wherein a plurality of transverse chucks which are connected with a cylinder and are opposite two by two are arranged on the clamp base. When the pneumatic welding clamp is used, a workpiece is arranged between the two opposite transverse chucks, and the two transverse chucks are driven by the cylinder to clamp the workpiece; and after the welding is completed and when the stress is generated inside the workpiece, the workpiece tends to deform, the transverse chucks adjust automatically and constantly to find a new clamping force balance point under the action of the cylinder, so that the welding stress is released gradually, and the welding deformation degree of the aluminum alloy workpiece is reduced. When the workpiece is taken out, the transverse chucks are released only by controlling the cylinder, and the workpiece can be easily taken out of the clamp. Therefore, the pneumatic welding clamp is convenient to use.
Description
Technical field
The utility model relates to a kind of pneumatic weld jig, particularly a kind of pneumatic weld jig that is used for bullet train aluminium alloy chair framework welding procedure.
Background technology
Along with development of science and technology, the high-speed train chair technology is maked rapid progress, and under the target of energy-conservation loss of weight, present high-speed train chair adopts Al alloy parts more, and the scale welding in enormous quantities of Al alloy parts is produced and become inexorable trend.Because various aspects of performance such as the heat conduction velocity of aluminum alloy materials, stress release, post welding distortion and traditional steel are far from each other.And the characteristics that traditional welding clamp size " fixes " have caused Al alloy parts stress after welding too concentrated, make Al alloy parts be easy to generate distortion, Al alloy parts after the distortion is difficult to take out from anchor clamps, then be easy to generate the depression equivalent damage as taking out by force, serious words may crack owing to stress too concentrates on Al alloy parts.Therefore the traditional welding anchor clamps can not satisfy the technological requirement of aluminium alloy welding, and under the situation that technologies such as aluminium alloy manual welding, robot welding work station reach its maturity, the weld jig frock that exploitation matches with it is extremely urgent.
The utility model content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides a kind of pneumatic weld jig that can eliminate welding stress in welding process gradually.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of pneumatic weld jig comprises a clamp base, and described clamp base is provided with several horizontal chucks, and described horizontal chuck is connected with cylinder, and described several horizontal chucks are relative in twos.
Preferably, described clamp base is provided with several vertical chucks, and described vertical chuck is connected with cylinder.
Preferably, described clamp base is provided with several fixed chucks.
Preferably, described several fixed chucks lay respectively at the both sides of described clamp base and are symmetrically distributed side by side.
Preferably, the face that contacts with workpiece on described horizontal chuck, vertical chuck, the fixed chuck is a copper product.
Technique scheme has following beneficial effect: this pneumatic weld jig in use, workpiece is placed between two relative horizontal chucks, by two horizontal chuck clamping work pieces of air cylinder driven, like this after welding is finished, workpiece is inner to produce stress and when trending towards deforming, laterally chuck is constantly adjusted automatically and found new clamping force equalization point by the effect of cylinder, welding stress is discharged gradually, thereby reduce the welding deformation degree of Al alloy parts.And when taking out workpiece, only need control cylinder that horizontal chuck is loosened, and just can easily workpiece be taken out from anchor clamps, very convenient.

Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of the horizontal chuck of the utility model embodiment.
Fig. 3 is the structural representation of the vertical chuck of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, 2, 3, this pneumatic weld jig comprises a clamp base 1, and clamp base 1 is provided with several horizontal chucks 32, and laterally chuck 32 is connected with cylinder 4, and several horizontal chucks 32 are relative in twos.Also be provided with several vertical chucks 31 on the clamp base 1, vertically chuck 31 is connected with cylinder 4.Clamp base 1 both sides are provided with several fixed chucks 2, and fixed chuck 2 is symmetrically distributed on clamp base 1 side by side.The number of above-mentioned horizontal chuck 32, vertical chuck 31, fixed chuck 2 and position need to change according to the variation of the workpiece shape that will weld.
This pneumatic weld jig at first uses 2 pairs of workpiece of fixed chuck to carry out Primary Location in use, pushes down workpiece by fixed chuck 2, the X axis one-movement-freedom-degree and the Z axle rotational freedom of constraint workpiece.Then workpiece is placed between the relative horizontal chuck 32, by horizontal chuck 32 clamping work pieces of air cylinder driven, laterally chuck 32 can retrain the workpiece Y-axis to one-movement-freedom-degree and X-axis rotational freedom.By the vertical chuck 31 of cylinder 4 process lever pushing, make vertical chuck 31 push down workpiece simultaneously, the Z of constraint workpiece moves axially the free degree and Y-axis rotational freedom.Acting in conjunction by said fixing chuck 2, horizontal chuck 32, vertical chuck 31 can be fixed on workpiece on this pneumatic weld jig like this, can weld workpiece then.
After welding is finished, workpiece is inner to produce stress and when trending towards deforming, relative horizontal chuck 32 is constantly adjusted automatically and found new clamping force equalization point by the effect of cylinder, thereby welding stress is discharged gradually, reduce the welding deformation degree of Al alloy parts.And when taking out workpiece, only need control cylinder that horizontal chuck 32, vertical chuck 31 are unclamped, and just can easily workpiece be taken out from anchor clamps, very convenient.Laterally the face that contacts with workpiece on chuck 32, vertical chuck 31, the fixed chuck 2 all adopts copper product to make, and can avoid Al alloy parts and the direct of steel clamps to contact, to prevent the generation of galvano-cautery.
More than pneumatic weld jig that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; in sum; this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
