Abstract

The invention provides a tube welding and locating device for production. The tube welding and locating device for production comprises a fixing frame, a supporting plate, a first tube locating piece,a second tube locating piece and a third tube locating piece. The fixing frame comprises a first fixing plate and a second fixing plate which are parallel. A connection plate is perpendicularly and fixedly connected between the first fixing plate and the second fixing plate. One side of the connection plate is fixedly connected with the supporting plate. The first tube locating piece is arrangedinside the first fixing plate. The second tube locating piece driven by a lifting drive mechanism is arranged inside the second fixing plate. The upper surface of the end, far away from the connectionplate, of the supporting plate is provided with a sliding groove. The sliding groove is parallel with the connection plate. A sliding block is arranged in the sliding groove in a penetrating manner.A supporting rod used for supporting the third tube locating piece is arranged on the upper side of the sliding block. The top end of the supporting rod is detachably and fixedly connected with the third locating piece. The tube welding and locating device for production is convenient to use, capable of conducting welding and locating on tubes of different specifications, good in welding accuracyand good in welding effect.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to a pipe fitting welding positioning device for production. Background technique [0002] Welding is a common processing operation of pipe fittings. When welding pipe fittings, if the welded pipe fittings are not fixed, the pipe fittings are prone to shift or shift during the welding process, which affects the welding accuracy and welding quality, resulting in low welding processing efficiency. Defective products increased. Therefore, in order to improve welding precision and welding quality, it is usually necessary to position the pipe fittings to be welded during the welding process. [0003] Most of the existing welding positioning devices for pipe fittings are positioning welding devices for two straight pipe fittings. In industrial production, there will be situations where straight pipe fittings and bent pipe fittings are welded. Due to the special structure ...
