A gap adjustment device for butt welding of steel plates

Abstract

The invention discloses a steel plate butt welding gap adjusting device, and belongs to steel plate position adjusting devices. The problem that according to an existing steel plate butt welding positioning device, the butt welding steel plate gap is difficult to precisely adjust is solved. The device comprises a base assembly, a fixing assembly, a transmission mechanism, a positioning mechanism and a gap indicating assembly; the base assembly comprises a bottom plate, a front guide rail and a rear guide rail; the fixing assembly comprises a left fixing plate, a right fixing plate, a left pressing plate and a right pressing plate; the transmission mechanism comprises a transmission shaft, a reverse shaft, a front screw and a rear screw; the positioning mechanism comprises a left camshaft, a right camshaft, a left long positioning sliding block, a right long positioning sliding block, a left short positioning sliding block, a right short positioning sliding block, a left pressing strip, a right pressing strip, a left shifting fork, a right shifting fork, a left driving rod, a right driving rod and a positioning pin; the gap indicating assembly is composed of a left pointer, a right pointer and a ruler; the device is simple in structure, low in manufacturing cost, small in work environment influence, easy and convenient to operate, capable of ensuring the steel plate butt welding gap and precise positioning and greatly improving the welding quality and the welding efficiency and suitable for multiple welding processes of lasers, electric arcs and the like.

Description

technical field [0001] The invention belongs to a steel plate position adjustment device, in particular to a steel plate butt welding gap adjustment device, which is used in laser, arc and other welding processes of steel plates. Background technique [0002] Butt welding between steel plates is the most common connection method in laser, arc and other welding processes. During the butt welding of steel plates, the gap between the butt surfaces of the steel plates and the coplanarity of the upper surfaces have a decisive influence on the quality of the welded joint. The Chinese patent with authorized announcement number CN103381531B (authorized announcement date July 08, 2015) discloses a steel plate butt welding positioning device and alignment method, including a C-shaped bending plate, a connecting plate, and a connecting plate for fixing a C-shaped plate. The groove of the bent plate, the C-shaped bent plate is fixed in the groove, and a connecting plate and two C-shape...
