Description
Technical field
The present invention relates to auto parts welding tooling field, be specifically related to a kind of electromagnetic levitation type weld holder.
Background technology
In machine-building process, often need become parts to multiple part together assembly welding, as shown in Figure 1 a kind of automobile fore-stock parts.This automobile fore-stock 10 comprises tapered end 11, first supporting plate 12, second supporting plate 13, the mutual assembly welding of intermediate sleeve 14 forms, hole wherein on the first supporting plate 12 and the second supporting plate 13 needs coaxial with intermediate sleeve 14, tapered end 11 weld with the first supporting plate 12 and the second supporting plate 13 above, mutual alignment requirement registration.Be weld together successively each in common process, part positioning precision is poor, and product percent of pass is low, and production efficiency is low, and homogeneity of product is poor.
Now be badly in need of a kind of hole when can improve the welding of automobile fore-stock on the first supporting plate and the second supporting plate and the welding support of intermediate sleeve axiality as can be seen here.
Summary of the invention
The object of the present invention is to provide a kind of hole when can improve the welding of automobile fore-stock on the first supporting plate and the second supporting plate and the welding support of intermediate sleeve axiality.
For achieving the above object, base case of the present invention is: electromagnetic levitation type weld holder, comprise base plate, described base plate is provided with main support column, this main support column is provided with support bar, this support bar is provided with the cannelure in radially direction, in this cannelure, ring electromagnet is installed, described support bar is provided with the controller for controlling ring electromagnet, this ring electromagnet is placed with the many steel bars be evenly arranged, this steel bar is provided with the cambered surface matched with the endoporus radian of workpiece to be welded, multiple uniform permanent magnetic iron block that can repel each other with ring electromagnet is embedded with in this steel bar, described support bar is provided with the annular permanent magnet be slidably connected with it.
Operation principle and the advantage of this programme are: during concrete this weld holder of use, first annular permanent magnet is taken off from support bar, first supporting plate, intermediate sleeve, the second supporting plate are arranged on successively on support bar, the steel bar now on ring electromagnet is successively through the hole on the hole on the first supporting plate, intermediate sleeve and the second supporting plate.By controller, ring electromagnet is energized, now ring electromagnet and permanent magnetic iron block produce repulsive force (i.e. magnetic force), and now steel bar is under the effect of repulsive force, and steel bar is close on the first supporting plate, intermediate sleeve and the second supporting plate.Then annular permanent magnet is enclosed within support bar, and the first supporting plate (or second supporting plate) holds by annular permanent magnet.Then weld on the hole on the first supporting plate, intermediate sleeve and the second supporting plate.After the hole on the first supporting plate, intermediate sleeve and the welding of the second supporting plate terminate, make ring electromagnet power-off by controller, now steel bar does not contact with the automobile fore-stock after welding, the automobile fore-stock contact after welding is taken off from support bar.
This programme is ingenious uses the principle that magnet has homopolar-repulsion, the contact realizing steel bar and workpiece be separated.By same steel bar to the first supporting plate, intermediate sleeve and the second supporting plate radial location, realize many steel bars and locate simultaneously, be evenly arranged because the steel bar on ring electromagnet is many, and then improve axiality when automobile fore-stock welds.
Preferred version one: based on the preferred version of scheme, the bottom of described main support column is provided with the first elastic component, and the end of this first elastic component is provided with pressing plate.During concrete use this programme, pressing plate carries out spacing to workpiece, place work piece on support bar along the axial direction play of support bar.
Preferred version two: the preferably preferred version of: described base plate is also provided with secondary support column, this pair supports Your Majesty and is provided with the second elastic component, and the end of this second elastic component is also provided with pressing plate.Pressing plate on pressing plate on first elastic component and the second elastic component carries out two-way location to workpiece, advantageously in spacing on support bar of workpiece.
Preferred version three: the preferably preferred version of two: one deck elastic layer all installed by the pressing plate on described first elastic component and the pressing plate on the second elastic component, described annular permanent magnet is bonded with elastic bumps.Elastic layer and elastic bumps have been all effects of protection workpiece, avoid workpiece to damage because of spacing in spacing process.
