Tailored welding tooling and welding method for lower frame

Abstract

The invention relates to a tailor welding tool for a lower frame body, comprising: a base, two positioning devices arranged symmetrically; Screw holes and adjustment screw holes and the positioning slider connected to the bottom plate through the transverse guide rail, each end is provided with a drive shaft that is adapted to the positioning screw hole and one-to-one corresponding to the threaded segment, and two are connected to the adjustment screw hole. A center beam positioning screw corresponding to the screw connection, a positioning stepping motor connected with the bottom plate, a driving gear connected with the output shaft of the positioning stepping motor, a driven gear connected with the driving shaft and meshed with the driving gear; two thread segments The screw threads of the first positioning device are connected with the upper end of the base through longitudinal guide rails; the bottom plate of the second positioning device is detachably connected with the upper end of the base; the first positioning device is equipped with a displacement device.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a tailor welding tool for a lower frame and a tailor welding method. Background technique [0002] The car is a box-shaped space used by the elevator to carry and transport people and materials; the car is composed of the car floor, car wall, car roof, car door and other main components. base plate for body connection; if attached image 3 As shown: the lower frame includes: a front beam and a rear beam with grooves passing through both ends on the opposite end faces, and the two ends are inserted into the middle of the groove provided by the front beam and the rear beam one by one, and correspond to the front beam and the rear beam one by one For the welded center beam, the width of the lower end of the front beam and the rear beam is greater than the width of the upper end; currently, during tailor welding, the front and rear lengths of the lower frame, the symmetry between the two end...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the current tailor welding, the front and rear length of the lower frame, the symmetry between the two ends of the front beam and the two ends of the rear beam relative to the middle beam are manually controlled, there are the front and rear length of the lower frame, the two ends of the front beam The symmetry of the two ends of the rear beam relative to the middle beam is not stable enough, and the front and rear length of the lower frame, the symmetry of the two ends of the front beam and the two ends of the rear beam relative to the middle beam are stable, and the tailor welding tooling and tailor welding of the lower frame are provided. method
