no. 1 approach

[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: two workpieces W1 and W2 formed by stamping 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 operations. The operator H1 The workpieces W1 and W2 are mounted on the workpiece positioning device 2 on the opposite side of the welding robot 3 .

[0027] The workpiece positioning device 2 includes a drive motor 4, a rotating frame 5 (rotating body), and a clamp 6. The drive motor 4 has a rotating shaft 4a extending up and down. The rotating frame 5 is supported by the rotating shaft 4a and has a rectangular frame shape. The clamp 6 There are four and the above-mentioned workpieces W1 and W2 are positioned, and the above-mentioned rotating frame 5 is located at a position corresponding to the a...

[0063] Figure 4 and Figure 5 A second embodiment of the present invention is shown. In this second embodiment, only the shape of the second horizontal frame 52 , the portion that rotates the third horizontal frame 53 , and the number of clamps 6 are different from those of the first embodiment, and the others are the same as the first embodiment, so the following only Different parts from the first embodiment will be described in detail.

[0064] The linear frame 52a of each second horizontal frame 52 in the second embodiment is shorter than the linear frame 52a of the first embodiment.

[0065] A clamp rotation motor 8 is attached to the inclined frame 52b on one end side in the longitudinal direction of each of the second horizontal frames 52 on the opposite side to the third horizontal frame 53, and the clamp rotation motor 8 is connected to the above-mentioned third horizontal frame through an output shaft. The above-described third horizontal frame 53 is rotated in s...

Abstract

The rotating frame (5) includes a first horizontal frame (51) extending from the rotating shaft (4a) to both sides of the horizontal direction, and from the two ends of the length direction of the first horizontal frame (51) to the first horizontal frame (51) respectively. A pair of second horizontal frames (52) extending in the orthogonal horizontal direction and a pair of third horizontal frames (53) bridging the lengthwise end portions of the second horizontal frames (52) to each other; Clamps (6) are installed on the frame (53). The third horizontal frame (53) is supported on each second horizontal frame (52) by cross roller bearings (B1), and the third horizontal frame (53) is rotatable.

Description

technical field [0001] The invention relates to a workpiece positioning device, for example, a workpiece positioning device for clamping and positioning a workpiece obtained by stamping and forming during welding. Background technique [0002] The prior art is such that, for example, the apparatus disclosed in Patent Document 1 includes a rotary table having a rotating shaft extending in an up-down direction, a plurality of jigs, and a welding robot, and a plurality of jigs are provided 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 is rotated and tilted around a rotation axis extending in a direction intersecting the radial direction of the rotary table . By tilting each of the above-mentioned jigs when the operator performs the work of mounting the workpiece on the jig or the welding robot performs the welding operatio...
