Embodiment Construction
[0053] In order to facilitate the understanding of the present invention, the laser welding equipment system and its welding method will be more fully described below with reference to the relevant drawings. The preferred embodiment of the laser welding equipment system and its welding method is given in the accompanying drawings. However, the laser welding equipment system and its welding method can be implemented in many different forms and are not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the laser welding equipment system and its welding method more thorough and comprehensive.
[0054] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or...

The invention relates to a positioning device, a positioning method, a laser welding system and a welding method of the laser welding system. The above positioning device is used for positioning a first workpiece and a second workpiece, and comprises a base, a sliding base, a driving mechanism, a motion controller, a first rotation clamping mechanism and a second rotation clamping mechanism, and the base comprises a base body and a fixing base which are connected; the sliding base is connected to the base body in a sliding manner, and the sliding base and the fixing base are oppositely arranged; and the driving mechanism comprises a moment servo motor, and the moment servo motor is arranged on the base body. According to the above positioning method, a laser range finder or a vision imaging system and other measuring tools are not needed for achieving gap positioning between the first workpiece and the second workpiece, a better magnetic force gap can be achieved, and the assembly costof a solenoid valve can be greatly reduced.
Description
technical field [0001] The invention relates to the technical field of electromagnetic valve manufacturing, in particular to a laser welding system and a welding method thereof. Background technique [0002] The solenoid valve includes a first magnetic core, a second magnetic core and a welded pipe. When assembling, both the first ferromagnetic core and the second magnetic valve core are welded on the welded pipe, so that the first ferromagnetic core, the second magnetic valve core and the welded pipe are connected together. Before welding, the first ferromagnetic core and the second magnetic core The accuracy of the gap between them is required to be high to ensure that the solenoid valve has a good magnetic gap. [0003] If the assembly process of the solenoid valve adopts the method of controlling the accuracy of the associated workpieces to achieve the final gap accuracy requirements, the two valve cores need to be finely ground separately to meet the requirements, and ...
