Four-way rotary locating device for spot welding of seat frame

Abstract

The invention relates to a welding locating device, in particular to a four-way rotary locating device for spot welding of a seat frame. The locating device comprises a support frame and a support beam arranged on the support frame; the support beam is connected with a sliding rail I which is provided with a sliding block I capable of sliding relative to the sliding rail I; the sliding block I is connected with a big sliding block mounting plate capable of sliding together with the sliding block I; the big sliding block mounting plate is connected with a sliding rail II vertical to the sliding rail I; the sliding rail II is provided with a sliding block II capable of sliding relative to the sliding rail II; the sliding block II is connected with a small sliding block mounting plate capable of sliding together with the sliding block II; the small sliding block mounting plate is fixedly connected with a bearing sleeve; a bearing is arranged at the inner side of the bearing sleeve; a rotating shaft is supported in the bearing; the end of the rotating shaft protruding out of the upper end of the bearing sleeve is fixedly connected with a tray capable of rotating together with the rotating shaft; and the tray is connected with a workpiece locating frame used for supporting the seat frame. The four-way rotary locating device has the advantages of effectively lightening the labor intensity of workers and improving the welding accuracy and production efficiency.

Description

technical field [0001] The invention relates to a welding positioning device, in particular to a spot welding positioning device. Background technique [0002] The car seat frame is usually connected by spot welding. Spot welding usually requires many welding positions. It is not easy to control the welding position accurately when using automatic welding with manipulators. The high cost of automatic welding production lines with high position accuracy is not conducive to the promotion and application of small and medium-sized enterprises. Most small and medium-sized enterprises still use manual welding. Manually weld a welding point, and then weld the next welding point, because the welding points are not at the same place and sometimes the distance is relatively large, usually after welding a point, the workpiece must be moved, or the welding tool must be moved to the edge of another point, so that Not only is the labor intensity of the workers high, but the work efficien...

Manually weld a welding point, and then weld the next welding point, because the welding points are not at the same place and sometimes the distance is relatively large, usually after welding a point, the workpiece must be moved, or the welding tool must be moved to the edge of another point, so that Not only the labor intensity of the workers is high, but the work efficiency is low, and the multiple movement of the workpiece is easy to affect the clamping accuracy, which in turn affects the welding accuracy
