Description

Laser welding positioning device Technical Field The utility model relates to a clamping and positioning device, in particular to a laser welding and positioning device. Background The laser welding is a material processing method, mainly uses high-energy laser pulse to locally heat the material surface in a micro area, then the energy of laser radiation is led to the inside of a workpiece to be diffused through heat transfer, and the workpiece is melted to form a specific molten pool so as to achieve the purpose of welding. The laser welding positioning device comprises a truss, a supporting plate, a cover plate and a power assembly, wherein a top plate and a bottom plate are vertically and alternately distributed on the truss, the supporting plate is movably connected with the bottom plate, a sinking groove is formed in the supporting plate and is used for placing a lower workpiece, a limiting assembly is arranged in the sinking groove, the cover plate is movably connected with the top plate, at least one group of telescopic sources are arranged on the cover plate, movable rods of the telescopic sources vertically extend downwards and are connected with a ring plate, the ring plate is in threaded connection with a plurality of supporting rods, the supporting rods can support an upper workpiece in the middle of the ring plate, the power assembly is arranged on the bottom plate, the power assembly is connected with the supporting plate, the telescopic sources can drive the ring plate to move downwards so as to drive the upper workpiece to be in compression joint with the lower workpiece to form a welding position, and the power assembly can drive the supporting plate to rotate to adjust the welding position, so that welding can be finished at one time, welding quality is high, and welding bursting is avoided when a part of welding is subjected to position adjustment; The above-mentioned current laser welding positioner discovers some problems when using, at first utilize the power component of below to drive a work piece rotatory, and another needs to drive through frictional force, there is the possibility that slides when probably having between two work pieces, leads to the welding position not to harden under, and two work pieces produce relative motion, lead to the problem of welding inefficacy, and secondly when the centre gripping work piece, need the manual work stir spacing subassembly, with the stop gear such as butt pole, lead to the loaded down with trivial details problem of step of installing the work piece.
