[utility model content]
The purpose of this utility model is: a kind of device of holeless laser weld and the weldment of processing thereof are provided, utilize the device welding sheet metal component and the weldering nail of this holeless laser weld, weldering nail that need not the prefabricated band ailhead, also need not on sheet metal component, offer the weldering nail hole that matches with ailhead, contact-making surface position by laser beam irradiation sheet metal component and weldering nail, realize the rapid welding moulding, guarantee welding quality, reach the perfect precision requirement.
The technical solution of the utility model is achieved in that a kind of device of holeless laser weld, comprise laser-beam welding machine that is provided with the laser gun mouth and the welding fixture that is fixed on the laser-beam welding machine, offer the locating hole of weldering nail on the welding fixture, locating hole is built-in with the primary and secondary pin;
In the device of above-mentioned holeless laser weld, a pushing mechanism stretches in the described locating hole, and the primary and secondary pin places on the pushing mechanism;
The device of above-mentioned holeless laser weld, described pushing mechanism are cylinder.
The technical solution of the utility model also comprises: the weldment of the above-mentioned holeless laser soldering device processing of a kind of usefulness, described weldment comprises sheet metal component and weldering nail, isometrical axle about weldering is followed closely and is, the weldering nail is positioned in the locating hole of welding fixture, locating hole is built-in with the primary and secondary pin, weldering nail places on the primary and secondary pin, and sheet metal component is positioned on the working face of welding fixture and covers locating hole, and sheet metal component is a horizontal plane with the contact-making surface of weldering nail.
Than the device of common porose full circular laser weld and the weldment of processing, the beneficial effects of the utility model are: use welder of the present utility model that sheet metal component and weldering tack welding are connected together, omitted the operation of on sheet metal component, offering weldering nail hole and processing ailhead at weldering nail one end, thereby reduced processing cost, saved material and cut down the consumption of energy; The omission of sheet metal component perforate avoided causing that owing to the sheet metal component hole location is bad position degree after the product welding is bad, and the flatness of sheet metal component requires to lower relatively; The primary and secondary pin that is provided with in the locating hole makes the weldering nail remain in welding process with sheet metal component and contacts, and makes the height-precision of weldering nail require to reduce greatly, has further saved the processing cost of weldering nail; Because laser beam penetrates sheet metal component and makes itself and ailhead welding mutually during welding, the sweating heat stress distribution is vertical, and the stress influence that can not be heated after processing work ejects is out of shape, thereby avoids influencing the perpendicularity and the position degree of product; The welding quality height easily reaches the perfect precision requirement.
