After the completion of weldering, part and fixture adhesion, and the welding deformation of annular inner ring generation warpage, thickness direction warpage 0.3mm~
1.2mm.It is follow-up to take pincers worker to separate and carried out with fixture of heat treatment the process of thermostabilization processing, it just can guarantee that design drawing
It is required that.But part deformation is further increased during pincers worker separation part and fixture is taken, or even cause zero
Part is scrapped because of tear, and product qualification rate is low.
The content of the invention
The invention provides a kind of weld jig of multilayer thin-wall annular part laser circumference seam weld, solve in laser circumference
During seam weld, part and its adhesion are effectively prevented, eliminates welding deformation phenomenon, solves asking for part welding buckling deformation
Topic.
The technical scheme is that：A kind of weld jig of multilayer thin-wall annular part laser circumference seam weld, including red copper
Manufactured annular positioning disk, the chrome-faced of positioning disk；Matching has gland made of red copper, the surface plating of gland on positioning disk
Chromium；The side of positioning disk sets taper faced washer, and is cased with compressing the fastener of gland and positioning disk on taper faced washer；It is wherein fixed
Positioner is additionally provided between position disk and gland.
Further, the features of the present invention also resides in：
Mandrel is wherein installed with positioning disk, one end of mandrel is cylindrical structure, and the other end is threaded post.
Wherein a diameter of 20mm of the cylindrical structure of mandrel, and be clamped on the scroll chuck of stepper motor main shaft.
Wherein mandrel is stretched out on the outside of positioning disk for one end of threaded post, and fixing nut is cased with threaded post.
Wherein positioner is alignment pin, and alignment pin is arranged on positioning disk.
Wherein the middle part of positioning disk passes through Step Shaft, and taper faced washer is cased with the end of Step Shaft.
Wherein fastener is sphere band shoulder nut.
Several counterbores are also provided with wherein on gland.
Compared with prior art, the beneficial effects of the invention are as follows：Using positioning disk made of red copper and gland, its thermal conductivity
It is more preferable with thermal diffusivity, during laser circumference weld seam, it can effectively prevent welding deformation；Using chromium coating in the case of a high temperature
It can effectively prevent part from welding with chuck body to connect together.
Further, mandrel is fixedly connected with the positioning disk by fixing nut, while also passes through the circle configurations of mandrel
It is connected with the drive mechanism of stepper motor.
Further, alignment pin can prevent workpiece to be welded from relatively moving, for positioning the angular of workpiece to be welded
Relation.
Further, taper faced washer is combined with sphere band shoulder nut can make gland and positioning disk closely be pressed on one
Rise, and gland can be such that thrust is dispersed on workpiece to be welded, prevent the local because of thrust mistake of workpiece to be welded
Cause to deform greatly.
Further, multiple counterbores on gland can reduce contact area, make between positioning disk and gland compress by
Power is uniform.
Brief description of the drawings
