Accompanying drawing 1, be the technological equipment structure chart of positioning and processing method of the present invention;
Accompanying drawing 2, be that the technological equipment of positioning and processing method of the present invention is implemented stereogram.
The specific embodiment
Accompanying drawing 1 is the technological equipment structural representation of positioning and processing method of the present invention; Title by the technological equipment shown in the figure is a locating support; One cover technological equipment is made up of the locating support of three above fixed settings; Each part locating support is independently parts, and the through hole 1 in the middle of the locating support is to match with the external diameter of cylindrical shell, and three small through hole 2 tangent with intermediate throughholes cooperate with the external diameter of support bar.Accompanying drawing 2 is stereograms that the technological equipment of positioning and processing method of the present invention is implemented; During use with cylindrical shell 3 pass one the cover technological equipment through hole; Cylindrical shell 3 just is erected on the locating support 4; Then three support bars are inserted the aperture of locating support, the radial position between cylindrical shell and the support bar just has been fixed.After then adjusting the endface position of cylindrical shell and support bar,,, just can implement to have welded to confirm the position dimension between solder joint along the locating support that moves axially of cylindrical shell and support bar.Move the weld job of whole product of 48 locating support completion, the radial accuracy between cylindrical shell and the support bar requires to be given to have guaranteed by locating support.The both sides at the macropore of locating support and place, aperture point of contact are respectively removed 2 millimeters, are to be the solder joint slot milling.Implementation step is following:
Step 1, the arrangement technology equipment
The use of this cover technological equipment needs configuration platform, and the length of platform must be greater than the length of the object that is positioned, and the flatness error of platform is less than 0.03 millimeter/meter.
Locating support quantity look the object that is positioned axial dimension and decide, it is many that the quantity that promptly axial dimension is big just needs, at least three; One axially extending bore is arranged on locating support, and the external diameter fit clearance of the size in its aperture and cylindrical shell is 0.15~0.2 millimeter; The edge of locating support axially extending bore is uniformly distributed with the through hole of 10 millimeters of three diameters, and these three apertures are mutually circumscribed with the locating support through hole; The fit clearance of through hole that diameter is 10 millimeters and support bar external diameter is 0.1~0.2 millimeter; Bilateral symmetry axial along aperture, the point of contact line respectively cuts 2 millimeters, forms the rectangle hole of 4 mm wides; The centre-height size of one group of locating support through hole and apart from the size of two sides, the size inconsistency of these three directions is less than 0.05 millimeter, and the direction of mark location support;
Step 2 is confirmed the locating support technical parameter
Confirm the inconsistent degree difference in position of axial hole and aperture on the gap, locating support of centre-height error, support bar diameter and support aperture of fit clearance, locating support of barrel diameter and support axially extending bore;
Step 3, processing cylindrical shell, process support bar:
By the fit clearance requirement of locating support and cylindrical shell and support bar, processing cylindrical shell, process support bar.
Step 4, use technological equipment are implemented the location to cylindrical shell and support bar:
Be placed on one group of locating support on the platform by its same direction position.The cylindrical of cylindrical shell is passed the axially extending bore of one group of same direction locating support successively, and cylindrical shell is erected on the locating support.
Every support bar is passed the aperture in the locating support successively, and three support bars just are limited to be positioned at the outer round surface of cylindrical shell after accomplishing; After the axial location adjustment to cylindrical shell and support bar, just can get into welding procedure;
Step 5, cylindrical shell and support bar behind the location are implemented welding: at the axial location running fix support of cylindrical shell and support bar, to regulate and the seat of demonstration solder joint.Be every adjustment, sortie of running fix support, just can implement the location dimension operation of hexad solder joint, running fix support 48 sorties are accomplished whole location weld jobs.
Step 6, welding procedure finish to unload technological equipment, accomplish member processing.

The axially extending bore diameter dimension of above-mentioned unidirectional one group of locating support and the inconsistency of position dimension are less than 0.05 millimeter;
The function of locating support limits the mutual radial position of cylindrical shell and support bar on the one hand, has overcome the distortion of cylindrical shell and support bar simultaneously, and it is fixing to implement welding then, has eliminated the error that causes because of distortion.
The largest cumulative error of member processing of the present invention is considered local welding deformation (the spot welding deflection of symmetry is little) less than 0.8 millimeter, and total deflection is less than 1 millimeter, so adopt the member of this technological equipment location back welding to meet design requirement.
The present invention is simple and easy and effective, and is efficient and practical, the technological orientation that has solved ultra slenderness ratio member; Broken through and produced key; Need not to form the loaded down with trivial details adjustment of two part mutual alignment sizes of member, size Control effectively, reliable, quality has obtained practical assurance.
Be the processing method of not using technological equipment as follows, compare with the present invention obviously consuming time, consumption power processed complex, cost is expensive.
Embodiment 1
The length of cylindrical shell is 4500 millimeters, 108 millimeters of outside diameters, 4 millimeters of wall thickness.10 millimeters of the diameters of support bar, 4600 millimeters of length.The designing requirement of member is: the outer round surface of cylindrical shell is with fixing three support bars of the process of spot welding.
At first control the excircle dimension precision of cylindrical shell and support bar, outer surface (promptly tangent) back that support bar is fitted in cylindrical shell is implemented two solder joints in first place and is fixed, and accomplishes first place and has fixedly just established the mutual alignment of rear cylinder body and support bar axial line.Second fixing point fitted according to method two cylindricals of first fixing point, and apart from first fixing point two solder joints at enforcement second place in the vertical direction (Y direction) of (cylindrical shell and the support bar center of circle are through the line at the point of contact) ± 0.5 millimeter scope radially.48 follow-up by that analogy places, 96 solder joints are all after two cylindricals are fitted; Centering is fixing apart from vertical direction (Y the direction) ± 0.5 millimeter interior enforcement welding of scope radially of first fixing point, just can guarantee that the support bar axial line and the cylindrical shell axial line both direction depth of parallelism (being directions X, Y direction) are less than 1 millimeter requirement.
Embodiment 2
First support bar comes into effect latter two process after the cylindrical shell outer round surface is fixing---the fixedly welding of second support bar, the 3rd support bar.After this each crossed the Cheng Qian and wanted the support bar of first this process of centering and 120 ° of locus of first support bar.And to control two axial correspondence positions of solder joint of per two solder joints and first support bar bearing of 48 bearings, to guarantee the solder joint axial location requirement of 48 groups of members.So the workload of centering, adjusting is very big, difficulty is also very high, and the reliability of technology is also low, thereby is difficult to guarantee product quality.
