Description

Technical Field

[0001] The utility model relates to the technical field of positioners, in particular to a positioner for a ground rail type welding robot workstation. Background Art

[0002] The positioner is a special welding auxiliary equipment, suitable for welding position shifting in rotary work to obtain the ideal processing position and welding speed. It can be used in conjunction with the operator and welding machine to form an automatic welding center, and can also be used for workpiece position shifting during manual operation. The worktable rotation adopts stepless speed regulation by the frequency converter with high speed regulation accuracy. The remote control box can realize remote operation of the worktable, and can also be connected with the operator and welding machine control system to realize linkage operation.

[0003] In the prior art, when mechanically welding some longer steel plates, the positioner is divided into a positioner headstock and a positioner tailstock, thereby clamping and positioning the workpiece. However, currently, usually only the positioner tailstock can be moved, resulting in limited positioning, thereby reducing work efficiency. Utility Model Content

[0010] A further improvement of the technical solution of the utility model is that a driving rod is fixedly installed on the top of the rotating gear, the other end of the driving rod extends to the top of the supporting plate, and a driving disk is fixedly installed on the other end of the driving rod.

[0011] A further improvement of the technical solution of the utility model is that a handle is fixedly installed on the top right side of the driving disk, a positioning rod is movably inserted inside the handle, and the bottom end of the positioning rod passes through the driving disk and is movably inserted inside the positioning hole.

[0012] A further improvement of the technical solution of the utility model is that: the positioning unit includes a lower clamping plate fixedly mounted on the bottom end of the inner part of the moving seat, upper clamping plates are slidably connected to the two sides of the moving seat above the lower clamping plate, an electric telescopic rod is fixedly mounted on the top of the upper clamping plate, and the other end of the electric telescopic rod is fixedly mounted on the top bottom end of the moving seat, and rubber bumps are fixedly mounted on the inner surfaces of the lower clamping plate and the upper clamping plate, and the rubber bumps can enhance the friction between the clamping piece and the workpiece, thereby promoting the effect of stable clamping.

[0013] A further improvement of the technical solution of the utility model is that a rotating groove is opened at the top of the sliding convex strip, and a roller is rotatably installed inside the rotating groove. When the movable seat moves, friction is generated between the movable seat and the roller, and the friction force causes the roller to rotate.

By arranging two groups of moving seats, a rotating handle drives a driving disk to cause a driving rod to drive a rotating gear to rotate, and the rotating gear is meshed and connected with teeth. Since a brake plate is fixed, the meshing and staggered movement causes the moving seat to slide on the top of the bearing base, and the position and spacing of the two groups of moving seats can be adjusted at will, thereby promoting the effect of position adjustment.

[0016] The utility model provides a positioner for a ground rail type welding robot workstation. Rollers are arranged so that the bottom end of a moving seat contacts the rollers when the moving seat slides. The rotation of the rollers promotes the smoothness of movement and reduces friction.

[0017] The utility model provides a positioner for a ground rail type welding robot workstation. By arranging an upper clamping plate and a lower clamping plate, the upper clamping plate is gradually brought close to the lower clamping plate by starting an electric telescopic rod, so that a workpiece between the two can be clamped and positioned.
