DETAILED DESCRIPTION

[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] like Figure 1 , Figure 2 , Figure 3As shown, a scaffolding automatic welding device is used to weld the vertical pole 5 and the fastener 6 in the scaffolding. The utility model includes a welding machine mechanism and a workpiece rotating mechanism. In the prior art, the welding machine mechanism includes both a single-station movable welding machine and a welding machine with multiple stations welding at the same time. The utility model will not be described in detail here. In order to facilitate the connection between the motor and the vertical pole 5 so that the motor drives the vertical pole 5 to rotate, the workpiece rotating mechanism of the utility model includes a base 1, and a power unit 2 and a clamping unit 3 are arranged at both ends of the base 1. A bracket 4 for supporting the vertical pole 5 is arranged between the power unit 2 and the clamping unit 3;

[0021] The power unit 2 includes a motor, which is fixedly connected to a first socket 21 for inserting into the vertical pole 5;

[0022] The clamping unit 3 includes a hydraulic cylinder 31, which is connected to a slide seat 32, which is slidably connected to a slide rod 33, and the end of the slide rod 33 away from the hydraulic cylinder 31 is fixedly connected to a push plate 34, a spring 35 sleeved on the slide rod 33 is arranged between the slide seat 32 and the push plate 34, a bearing is arranged in the middle of the push plate 34, the bearing is connected to a rotating shaft, and the end of the rotating shaft away from the hydraulic cylinder 31 is fixedly connected to a second socket 36.

[0023] Specifically, the method of using the utility model is as follows: put the fastener 6 on the pole 5, then place the pole 5 on the bracket 4, and then start the hydraulic cylinder 31, the hydraulic cylinder 31 pushes the push plate 34 to move, so that the first socket 21 and the second socket 36 are connected with the two ends of the pole 5 respectively, and the first socket 21 and the second socket 36 clamp the pole 5, so that the motor can drive the pole 5 to rotate. In addition, a spring 35 is provided to prevent the hydraulic cylinder 31 from indirectly applying too much thrust to the motor, and the second socket 36 is connected to the bearing through the rotating shaft to facilitate reducing the rotation resistance of the pole 5. In addition, a PLC controller for controlling the welding machine and the motor to work automatically is also included, which will not be described in detail here.

[0024] Furthermore, the pressing unit 3 further comprises a slide rail 37 , on which a slider 38 is slidably connected, and the upper part of the slider 38 is fixedly connected to a slide seat 32 , and the slide seat 32 moves along the slide rail 37 .
