Point welding machine capable of achieving precise positioning

Abstract

The invention discloses a point welding machine capable of achieving precise positioning. The point welding machine comprises a cylindrical coordinate device and an euler angle positioning device. The cylindrical coordinate device comprises a disc base, an arc sliding block and a Z-axis scale rod. The euler angle positioning device comprises a precession angle positioning mechanism and a nutation angle positioning mechanism. The precession angle positioning mechanism comprises a precession angle chassis and a precession angle sliding block. The nutation angle positioning mechanism comprises a nutation angle chassis and a nutation angle sliding block. The point welding machine further comprises a welding arm, a point welding pen sliding block and a point welding pen. The phenomenon that a traditional point welding machine needs a standard for height measurement and a standard for angle measurement is changed, the operation steps are greatly simplified, the working efficiency is high, any point and the normal direction of the point inside the space curved surface of a product with the regular or complex appearance can be accurately positioned through the combination of the cylinder coordinate device and the euler angle positioning device, the precision is high, and the quality of the product is good.

Description

technical field [0001] The invention relates to a spot welding machine, in particular to a spot welding machine capable of precise positioning. Background technique [0002] The spot welding machine adopts the principle of double-sided double-point overcurrent welding. When working, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and the welding current flows from one electrode to the other. Instantaneous thermal fusion is formed at the two contact resistance points, and the welding current flows from the other electrode along the two workpieces to this electrode to form a loop, without damaging the internal structure of the workpiece to be welded. [0003] With the development of modern industry, not only the appearance of products is more and more diversified, but also the manufacturing precision of products is getting higher and higher. The traditional spot welding machine ...

Problems solved by technology

[0003] With the development of modern industry, not only the appearance of products is more and more diversified, but also the manufacturing precision of products is getting higher and higher. The traditional spot welding machine can no longer meet the requirements of modern industry.

Before the product is put into mass production, because there is no complete set of welding molds, it is necessary to roughly find the position of the welding point with the help of ordinary rulers, angle gauges and other tools. However, it is difficult to find the precise point with the help of tools for products with complex shapes, especially for products The normal direction of the curved surface is not only cumbersome to operate, but also has low work efficiency and welding accuracy, which affects the quality of the product
