Embodiment 1

[0046] Embodiment 1 of the present invention provides a flexible laser welding tool for workpieces with curved surface structures. The system includes: a lattice support system, a lattice compression system, a control system, a base 1 and a substrate, such as figure 1 shown.

[0047] The base 1 is located at the bottom of the flexible laser welding tool, and the lattice support system is located on the upper part of the base 1 and is fixedly connected with the base 1 . The base 1 is preferably made of steel, and its size is designed according to actual needs, preferably 1m×1m to 3m×3m.

[0048] The dot matrix support system is composed of a plurality of dot matrix support units 2 arranged in a matrix. The dot matrix support system is mainly used to provide support for the back of the workpiece 4 to be welded. Each dot matrix support unit 2 is individually connected to the control system, and can Achieve the effect of independent control. The position and quantity of the lattic...

Embodiment 2

[0057] Embodiment 2 of the present invention relates to a method for controlling the use of flexible laser welding tooling for workpieces with curved surface structures:

[0058] S1. Use three-dimensional modeling software to calculate the lifting height of each lattice support unit 2 in the lattice flexible support system and the distance of each lattice pressing unit 3 to press down according to the workpiece model to be welded. The three-dimensional modeling software is preferably UG , SolidWorks calculation distance function.

[0059] S2. Assemble the workpiece 4 to be welded to the tooling, and according to the lifting height of each lattice support unit 2 and the pressing distance of each lattice pressing unit 3 calculated in S1, the tooling is initially adjusted through the control system, so that The position of each end pallet 5 can basically match the profile of the workpiece.

[0060] The preliminary adjustment process is as follows: set the lifting height of each ...

Abstract

The invention provides a flexible welding tool and control method for a curved-profile structural workpiece, belongs to the technical field of laser welding tools, and solves the problems of long product update cycle, high accumulated cost, low reaction speed, relatively low efficiency and the like caused by repair, adjustment and even remanufacturing of existing special tools. The tool comprisesa lattice supporting system, a lattice pressing system, a control system, a base and a substrate; the lattice supporting system comprises multiple lattice supporting units; the lattice pressing systemcomprises multiple lattice pressing units; each lattice pressing unit and each lattice supporting unit are connected with the control system separately; and each of the lattice pressing units and thelattice supporting units comprises a casing, a servo motor, a tail-end tray and a sliding screw. The flexible welding tool is used for fixing the curved-profile structural workpiece.

Description

technical field [0001] The invention relates to the technical field of laser welding equipment, in particular to a flexible welding equipment and a fixing method for workpieces with curved surface structures. Background technique [0002] The current laser welding tooling is mainly based on special tooling, that is, a single set of tooling is specially designed for the welding process requirements of a single workpiece, and is usually a special tooling, with low flexibility and poor adaptability to different parts. The design and manufacture of the entire tooling requires experience. Repeatedly discuss the design, verification, manufacturing, commissioning, repair and other processes. [0003] With the rapid increase in the current market's demand for product specialization, individualization, and diversification, the speed of product structure design changes is also accelerating. For the traditional special tooling design method, every time the product structure is replace...
