[0026] Figure 1 to Figure 3 The production line 1 according to the first embodiment of the present invention is shown. The production line 1 is as follows: the two stamped workpieces W1 and W2 are assembled into one body by spot welding. The production line 1 includes a workpiece positioning device 2 for positioning the workpieces W1 and W2 and a welding robot 3 for welding. The operator H1 The workpieces W1 and W2 are mounted on the workpiece positioning device 2 on the opposite side to the welding robot 3 .

[0027] Above-mentioned workpiece positioning device 2 comprises driving motor 4, rotating frame 5 (rotary body) and fixture 6, and driving motor 4 has the rotating shaft 4a that extends up and down, and rotating frame 5 is supported by above-mentioned rotating shaft 4a and is rectangular frame shape, and fixture 6 There are four and the above-mentioned workpieces W1, W2 are positioned. The above-mentioned rotating frame 5 is located at the position corresponding to th...

Abstract

A rotary frame (5) is provided with: a first horizontal frame (51) extending from a rotary shaft (4a) towards both sides in a horizontal direction; a pair of second horizontal frames (52) which respectively extend in a horizontal direction orthogonal to the first horizontal frame (51) from both ends of the first horizontal frame (51) in the longitudinal direction; and a pair of third horizontal frames (53) which bridge ends of each of the second horizontal frames (52) in the longitudinal direction. Jigs (6) are attached to the third horizontal frames (53). The third horizontal frames (53) arerotatably supported on each of the second horizontal frames (52) by cross roller bearings (B1).

Description

technical field [0001] The present invention relates to a workpiece positioning device, for example, a workpiece positioning device for clamping and positioning a workpiece obtained by press forming during welding. Background technique [0002] The prior art is as follows: For example, the device disclosed in Patent Document 1 includes a rotary table, a plurality of clamps, and a welding robot, wherein the rotary table has a rotating shaft extending in the up and down direction, and the multiple clamps are arranged on the rotary table. On the outer peripheral portion of the upper surface and for positioning the workpiece, the welding robot is arranged beside the rotary table, and each of the above-mentioned clamps rotates around the rotation axis and thereby tilts, and the rotation axis extends in a direction intersecting the radial direction of the rotary table . When the operator performs the work of installing the workpiece on the jig or the welding robot performs the we...
