Automatic tracking mechanism of laser welding machine

Abstract

The invention provides an automatic tracking mechanism of a laser welding machine. The automatic tracking mechanism comprises a bottom plate. The bottom plate is provided with a transverse sliding table and a longitudinal sliding table, wherein the transverse sliding table is located on the longitudinal sliding table, and the longitudinal sliding table can drive the transverse sliding table to move back and forth in the longitudinal direction. The transverse sliding table is provided with a supporting frame, the supporting frame is provided with a worktable, the worktable is connected to a lifting drive mechanism, a laser welding head is arranged above the worktable, distance measuring sensors are arranged in front, in the back, on the left and on the right of the laser welding head respectively, and the distance measuring sensors and the lifting drive mechanism are connected to a controller. According to the automatic tracking mechanism, there is no need to specially treat the laser welding head, just a special machine frame needs to be arranged for realizing the purpose, use is convenient, and the production cost is low and can be effectively lowered for enterprises.

Description

technical field [0001] The invention relates to the field of laser welding, in particular to an automatic tracking mechanism for laser welding. Background technique [0002] Laser welding machine, also often called laser welding machine and laser welding machine, is a machine for laser material processing. According to its working mode, it can be divided into laser mold welding machine, automatic laser welding machine, laser spot welding machine, and optical fiber transmission laser welding machine. Machine and optical welding is to use high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation diffuses to the inside of materials through heat conduction, and the materials are melted to form a specific molten pool to achieve the purpose of welding. Laser welding is the use of high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation diffuses into the interior of the material through heat conduction...

Problems solved by technology

However, both of the above two methods have certain disadvantages. The tracking force of the spring pressing the tracking head will be affected by the degree of relaxation of the spring itself, which may affect the moving speed of the welding torch and the quality of the welding surface; There are disadvantages such as high cost, complex structure and high maintenance cost
