Fixture device for steel plate laser welding machine and implementation method

Abstract

The invention relates to a fixture device for a steel plate laser welding machine. The fixture device mainly comprises an upper clamping plate mechanism, a lower clamping plate mechanism and a box body mechanism, wherein the upper clamping plate mechanism is used for clamping a steel plate; the lower clamping plate mechanism is used for flattening the steel plate; and the box body mechanism is used for mounting mechanical support of the upper clamping plate mechanism and the lower clamping plate mechanism. When the steel plate is conveyed between the two clamping plates through an automatic feed system; the upper clamping plate is pressed down through an upper clamping plate hydraulic cylinder; a positioning pin sleeve and a positioning pin rod are closed; a minitype hydraulic cylinder jacks up a flexible clamping plate along with a suspending sliding block; and the minitype hydraulic cylinder adopts pressure control and can tightly adhere the steel plate to the surface of an upper fixture, so that the flattening action is achieved. The fixture device can overcome the defect that the fixture cannot support the steel plate flatly caused by the plate type defects of the steel plate, solves the problems of clamping and flattening in the process of welding the thin steel plate, improves the welding quality of the thin steel plate and prolongs the service life of a fixture system. A steel plate laser welding machine fixture with a flattening function provided by the invention has simple design and a practicable process, and is convenient to popularize.

Description

Technical field: [0001] The invention relates to a fixture device, in particular to a fixture device and a realization method for a steel plate laser welder, in particular to a fixture device and a realization method for a steel plate laser welder with a leveling function. technical background: [0002] Steel plate laser welding machine is one of the most important equipment widely used in steel plate continuous production line. The function is to connect the tail of the previous steel coil with the head of the next steel coil to maintain the continuity of production. It is also widely used in automobile panel splicing production lines. Any welding quality problem will cause huge economic losses. [0003] The steel plate laser welding machine clamp is an important component of the equipment. When the steel plate laser welding machine clamps the steel plate to prepare for welding, the quality of the plate shape at the end of the steel plate plays a decisive role in the weld...

AI Technical Summary

Problems solved by technology

It can overcome the defect that the fixture cannot clamp the steel plate straightly due to the plate shape defect of the steel plate itself, especially solve the clamping and leveling problem of the thin steel plate welding, greatly improve the welding quality of the thin steel plate, and extend the Extends the service life of the fixture system
