Description
Technical field
The utility model relates to a kind of friction welding (FW) clamping device.
Background technology
Friction welding (FW) is a kind of newer welding manner, and it is that the heat that relies on two mutual power frictions of workpiece to produce causes metal to dissolve, with two welding manners that workpiece is integrally welded.Under the frictional force effect, the frictional interface of workpiece to be welded and near temperature thereof raise, and the resistance of deformation of metal reduces, plasticity improves, the interface oxidation film is broken, and when metal produced plastic flow, molecular diffusion and recrystallization by the interface realized welding.The difference of friction welding (FW) and traditional melting welding maximum is that in the whole welding process, the temperature that metal acquisition energy to be welded rising reaches does not reach its fusing point, and namely metal is that the class that realizes under the thermoplasticity state is forged the connection of attitude solid phase.Relatively traditional melting welding, friction welding (FW) have quality of weld joint height, welding efficiency height, steady quality, high conformity, can realize the advantages such as foreign material welding.
In concrete the use, the spin friction weldering is more common a kind of mode.But workpiece needs to overcome very large frictional resistance in rotation.Generally speaking, except increasing chucking power, increase exactly the coefficient of friction between workpiece and the clamper.If increase the chucking power of workpiece, may cause workpiece deformation, particularly for hollow workpiece.Therefore, increase the coefficient of friction between workpiece and the clamper, it is necessary just to seem.Coefficient of friction between the metal is difficult to overcome the large drag forces that workpiece rotating brings, and produces easily relative sliding between workpiece and the clamper, causes workpiece to make weld failure because skidding.Usually the way that increases coefficient of friction is that the contact-making surface to clamper and workpiece carries out specially treated, is coated with one deck Buddha's warrior attendant grains of sand, but the costing dearly of the Buddha's warrior attendant grains of sand, and when chucking power was very large, these coatings were easy to come off.
The utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of friction welding (FW) clamping device, is used for solving Buddha's warrior attendant grains of sand cost height and caducous problem on the contact-making surface of prior art clamper and workpiece.
Reach for achieving the above object other relevant purposes, the utility model provides a kind of friction welding (FW) clamping device, comprises the clamper of clamping work pieces, and the contact-making surface of clamper and workpiece is provided with a plurality of projections.Projection on the contact-making surface has increased the coefficient of friction of contact-making surface, makes workpiece carry out smoothly friction welding (FW), is difficult for skidding.
Preferably, projection is triangular prism.This projection can process by the mode of line cutting, and process is simple and convenient.
Further preferred, the incline of projection is parallel with the axis of clamper.Another kind of further preferred, the equidistant parallel distribution of projection.During workpiece rotating, the suffered direction of clamper is vertical with the incline of projection, has greatly increased the frictional force between clamper and the workpiece.
Preferably, contact-making surface is the face of cylinder.
Preferably, clamper comprises the fixed clamp device of the workpiece that is fixedly clamped and the rotating clamp fastener of clamping rotational workpieces.Further preferred, the fixed clamp device is cylindrical shape, is comprised of two fixed blocks, and fixed block is provided with a plurality of the first fixing holes.Another kind of further preferred, rotating clamp fastener is by forming along three chuck jaws that circumferentially are evenly distributed, and chuck jaw is provided with a plurality of the second fixing holes.In spin friction when weldering,, rotational workpieces rotates around own axle center under the drive of rotating clamp fastener, and the fixation workpiece clamper that is fixed is fixed, and the solder side phase mutual friction of rotational workpieces and fixation workpiece welds together rotational workpieces and fixation workpiece.
As mentioned above, the utility model friction welding (FW) clamping device has following beneficial effect:
This friction welding (FW) clamping device has adopted the contact-making surface between a kind of simple processing mode processing clamper and the workpiece, has greatly increased the coefficient of friction between clamper and the workpiece, and is with low cost, convenient durable.
