Supporting and fixing device for welding of pipe fittings

Abstract

The invention relates to the technical field of welding tools, in particular to a supporting and fixing device for welding of pipe fittings. The supporting and fixing comprises a bottom plate, two sets of fixed frames are arranged at the top of the bottom plate, top frames are fixedly connected to the tops of the fixed frames, rotating rods are arranged on left and right sides in the fixed frames,and bottoms of the rotating rods are rotationally connected with bottoms of inner sides of the rotating rods; the top of each rotating rod penetrates through the top of the fixed frame, the bottom ofeach rotating rod is connected with a worm wheel, the front side of the worm wheel is engaged with a worm, a left end of the worm is rotationally connected with a left side wall of the top frame, anda right end of the worm penetrates through a right side wall of the top frame, and a right side of the worm is connected with a handle; and external threads are oppositely arranged on the upper end and the lower end of each rotating rod. The supporting and fixing device disclosed by the invention is novel in design and convenient to use, not only can the rotation of the pipe fitting be realized,but also the alignment at the interface of the pipe fitting is convenient, and the welding of the pipe fitting is facilitated; in addition, the device is also convenient to move and fix, stronger in applicability and suitable for popularization and use.

Description

Technical field [0001] The invention relates to the technical field of welding appliances, in particular to a supporting and fixing device for pipe welding. Background technique [0002] Welding: also known as welding or welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Generally, in the welding process, the welding quality is the best when the object is welded at a square angle. The existing welding bracket cannot accurately fix the material accurately, cannot rotate or flip the material, and the welding is difficult. Welding low quality. [0003] For example, the Chinese patent application number is CN201720849565.6. A welding support device. The specific content is: a welding support device, including a base. The upper part of the base is equipped with support columns on both sides. The upper part is provided with a mounting groove, and a second gear is rotatably...

Problems solved by technology

Generally, during the welding process, when the object is welded at a flat angle, the welding quality is the best. When the existing welding bracket is used, it cannot accurately fix the material, rotate or flip the material, and the welding is difficult. low quality

[0003] For example, the Chinese patent application number is CN201720849565.6 a support device for welding, the specific content is: a support device for welding, including a base, support columns are installed on both sides of the upper part of the base, and the two support columns The upper part is provided with a mounting groove, and the second gear is rotated in the mounting groove, and a fixed column is installed on the upper part of the base close to the two supporting columns, and a rotating shaft is installed in the bearing, and the two ends of the rotating shaft They are respectively connected with two second gears, a fixed ring is installed between the two support plates, a first gear is installed in the middle of the fixed ring, the first gear meshes with the second gear, and the sliding The block is installed in the chute, and at least three object fixing devices are installed on the two ends of the fixing ring at equal distances in the circumferential direction. Although the invention can realize the rotation of the material to facilitate welding of the material from multiple directions, but in the case of During the fixing process of the pipe fittings, the device fixes the pipe fittings by turning the three bolts respectively. It is difficult to ensure that the left and right pipe fittings are at the same horizontal position when the bolts on both sides are screwed to fix, which is not conducive to the alignment of the two pipe fittings. bit
