Problems solved by technology

[0002] With the development of the mechanical field, more and more steel structures are used in all walks of life. In order to meet the structural requirements, welding forms of different structures are widely used. In order to ensure the strength requirements of the welded structure, most of the welding of medium and thick plates adopts V-groove welding is the welding form, and in a narrow space, due to the limitation of space and placement, the welding position of most V-groove welding forms is not ideal, and the swing of the welding torch and the welding angle of the welding torch are relatively poor. In order to meet the welding technical requirements and ensure the welding quality, it is necessary to change the position of the welding part so that the welding position can reach the ideal state and meet the welding technical requirements

Abstract

The invention discloses a portable manual positioner which comprises a base, a shaft box and a rotating disc. The rotating disc comprises a disc body which is provided with a central hole, and at least three radial T-shaped grooves are evenly formed in one end face of the disc plate. The shaft box comprises a box body which is connected with the disc body in a rotating mode through a vertical shaft, and the two ends of the box body are respectively provided with a horizontal shaft with the central axis perpendicular to the vertical shaft. The base is provided with a bottom plate and two supports arranged on the bottom plate at intervals, the two ends of each horizontal shaft are connected with the supports in a rotating mode, and positioning devices used for locking rotating angles are arranged between the vertical shaft and the box body and between the horizontal shafts and the supports. The portable manual positioner is suitable for welding of medium-small steel structures, a welding piece is fixed on the rotating disc through a clamp, the rotating disc is rotated to change positions and states of the welding piece according to requirements of welding modes and welding positions, and therefore the position and the state of the welding piece is made to be ideal, welding is facilitated, welding technical requirements are met, and welding quality is further guaranteed.
