Profiling device and numerical-control gate-type stringer welding machine using same

Abstract

The invention provides a profiling device comprising a shell. A rotating shaft is mounted on the shell and provided with a contact and a rocker; a resetting device is mounted on the rocker and connected with the shell which is provided with two sensors; and the free end of the rocker is arranged between the two sensors. The numerical-control gate-type stringer welding machine using the profiling device comprises a walking frame on which a walking power mechanism is mounted; a welding gun-moving mechanism is mounted on the beam of the walking frame and provided with a welding gun, a second profiler and a first profiler; the first profiler is the profiling device and comprises a first shell which is connected with the welding gun-moving mechanism and provided with a first rotating shaft; the first rotating shaft is provided with the first contact and the first rocket which is provided with the first resetting device; the first shell is connected with the first resetting device and provided with the second sensor and the first sensor; and the first rocket is arranged between the second sensor and the first sensor.

Description

technical field [0001] The invention relates to a welding device, in particular to a numerically controlled portal type longitudinal beam welding machine. Background technique [0002] At present, all kinds of gantry welding machines or gate-shaped welding machines on the market have low welding precision, and it is difficult to connect with the numerical control device to realize digital control in a real sense. The main reason is that the existing gantry welding machines or gate For shape welding machines, the sensing devices that control the welding torch to track the weld seam are all installed away from the welding torch. When the shape of the workpiece to be welded changes, the sensing device can sense the change in the shape of the workpiece only after the action of multiple parts. In order to adjust the time of the welding torch, the response sensitivity decreases, thereby reducing the welding accuracy. Even if it is connected with a high-precision numerical control ...
