Positioner is a kind of auxiliary equipment used for welding. It is suitable for welding displacement of rotary work, so as to obtain the ideal processing position and welding speed. It can usually be used with manipulators and welding machines to form an automatic welding center. The positioner can also be operated in the same way as the workpiece position during manual operation.
The traditional positioner is more complicated, costly, and the operation steps are more complicated. At the same time, manual assistance is required to perform the positional operation of the workpiece, which increases the labor intensity of the workers and reduces the displacement efficiency, which is difficult to meet the needs of modern high-speed production.
The positioner produced by Weld-Max includes a base, a turning shaft that is rotatably mounted on the base, a worktable fixed on the turning shaft, and a driving structure that drives the turning shaft to rotate. The driving structure includes a driving source, an output gear connected to the output end of the driving source, and a half gear meshed with the output gear and fixed on the turning shaft; the half gear has a toothed section for meshing with the output gear. The positioner also includes a protective structure. The protective structure includes a flexible protective cover arranged on the outer circumference of the toothed section, and the output gear is located in the flexible protective cover.
As a further improvement of the positioner of the utility model, the protective structure further includes a tension member arranged on at least one side of the output gear, and the side of the flexible protective cover away from the half gear is pressed against the surface of the tension member. And the tension member is a tension wheel which is rotatably installed on the base. The protective structure also includes an arc gear cover located between the flexible protective cover and the output gear, and the arc gear cover is fixed on the base. The half gear also has a linear section connecting the two ends of the tooth section, and the protective structure further includes a fixing plate and a fixing member passing through the fixing plate to fix the end of the flexible protective cover on the linear section. The fixing member is a screw.
The mounting seat includes a base and a mounting bracket located above the base, and the turning shaft is rotatably mounted on the mounting bracket. The working table has a working surface for installing the parts to be welded, and the half gear is located on the side of the working table away from the working surface.
The beneficial effect of the positioner produced by Weld-Max is that by setting a flexible protective cover, the toothed section of the half gear and the output gear are located in the protective cover to ensure that no debris enters between the half gear and the output gear and affects both The meshing ensures the meshing accuracy of the half gear and the output gear to ensure the turning accuracy of the worktable, while avoiding the wear of the half gear and the output gear, extending the service life of the two, and saving costs.
