[0017] like Figure 1 As shown, the utility model provides a double-station elbow welding positioning device, including a workbench 1, which is provided with two welding stations, and welds a base plate 10, an elbow 11 and a straight pipe 12 together. The welding stations include a mounting seat 3 symmetrically mounted on the workbench 1. Due to the need to cooperate with the inclined welding of the straight pipe 12, the surface of the mounting seat 3 is set as an inclined surface, and a placement groove is provided on the inclined surface. The two arms of the elbow 11 are placed in the placement groove. A toggle clamp 4 is installed on the mounting seat 3, and the toggle clamp 4 is used to fix the two arms of the elbow 11. Positioning seats 2 are installed at both ends of the elbow 11. The surface of the positioning seat 2 is in a fit state with the end face of the elbow 11, so that a recess is provided on the surface of the positioning seat 2. The bottom plate 10 is placed in the groove; the base 5 is installed on the workbench 1, and a shelf groove 1 is provided on the base 5. The middle section of the elbow 11 is placed in the shelf groove 1, and a positioning cover 6 is hinged on the base 5, and the positioning cover 6 is provided with a shelf groove 2 corresponding to the shelf groove 1, so that when the positioning cover 6 is covered on the base 5, the elbow 11 can be fixed, and the positioning cover 6 is locked on the base 5 by the locking assembly 7, so as to avoid the movement of the positioning cover 6 during welding; at the same time, the lifting platform 9 is movably installed on the workbench 1 by the cylinder 8, and the lifting platform 9 is symmetrically provided with positioning columns, and the straight pipe 12 is sleeved on the positioning columns, so that the position of the straight pipe 12 relative to the elbow 11 is controlled by controlling the cylinder 8.
