Description
Technical field
The utility model is related to mechanical field, more particularly to a kind of fixture of laser melting coating machine with repair swashing for cylinder crack
Light cladding machine.
Background technology
Nowadays welded for thin cylinder, usually clamped with three-jaw chuck, four paws chuck or roller is rolled and carried out
Direct clamping, is being welded after the completion of clamping, so not only expends man-hour, and is easily deformed in butt weld, and then
Cause to weld wrong weld seam, the weldquality simultaneously for welding also is difficult to hold, and the axiality that result in the cylinder of welding is poor.And
Operationally, the real work size of workbench can not be changed so that the limitation of welding thin cylinder than larger, and this
Technical side can clamp the carrying out of the cylinder to be welded so that the concentric docking of weld seam, while inside and outside clamping causes docking
Weld seam will not deform.Then conjugated using headstock and aircraft tail shelf, because tailstock can be moved along ground guide, it is possible to
Thin-wall barrel suitable for different size length is welded so that the performance of practicality is greatly improved.
It is related prior art discloses a kind of weld jig, its Authorization Notice No. is the application text of the U of CN 203696354
Part, wherein the first adjustment component promotes the first adjusting sleeve by screwing the first nut, the first nut, first connecting rod drives first to determine
Position plate is moved out, the inwall of first the first thin cylinder of location-plate stretching, positions the first thin cylinder.Meanwhile, second adjusts
Whole group part positions the second thin cylinder by with the first adjustment component identical mode.Due to the first threaded post and the second screw thread
Post is to be coaxially disposed, so as to ensure that the first thin cylinder and the second thin cylinder are coaxial docking, it is ensured that face of weld is fitted
Accuracy.After welding is finished, the first nut and the second nut are reversely rotated respectively, that is, unscrew the first nut and the second nut,
First connecting rod drives the first location-plate retraction, second connecting rod to drive the second location-plate retraction.Therefore dress in background technology is solved
Press from both sides the problem of the axiality of thin cylinder.It is straight in clamping identical for clamping different-diameter or the thin_wall cylinder part of thickness
Footpath is identical with the condition of the thin cylinder of thickness, if adjustment the first nut and the second nut, and then cause the first adjustment component
The purpose of the thin_wall cylinder parts that can just reach support different-diameter or thickness different with the support diameter of the second adjustment component.
And relative the first adjustment component and the second adjustment component by adjustment on substrate, presence can not be solved
The clamping of the thin_wall cylinder part in crack, and ensure the problem that its crack will not deform because of clamping.Because during clamping, the
One adjustment component and the second adjustment component can only be in report wall cylinders to outer support, and for the work of crannied thin cylinder
Part, when only to outer support, the stress at crack will be uneven, so that can cause that crack occurs different degrees of deformation, so that
Reduce the quality of weld seam.First is assembled during prior art is disclosed, in first threaded post and the second threaded post of support member to adjust
Component and second adjustment component, by rotate nut so that first adjustment component and second adjustment component carry out clamping support,
But can only limit with fixture in itself in the range of clamping, that is, to the welding between two thin cylinders, and for many
When individual thin cylinder is welded, a kind of weld jig for disclosing can not be solved, because coaxial between fixture and fixture
Degree problem cannot just be solved to it.
