Description

Technical Field

[0001] The utility model relates to the technical field of one-piece turbine shell welding devices, and specifically discloses a one-piece turbine shell gas shielded welding visual error-proofing device. Background Art

[0002] When welding small parts of a one-piece turbine casing, workers often accidentally install small parts (such as gaskets) upside down or backwards. Since the mounting holes of small parts can be turned around or inserted backwards, this leads to reverse welding, increasing quality risks and wasting small parts and turbine casings. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a visual error-proofing device for gas shielded welding of a conjoined turbine shell, which can greatly improve welding quality and reduce material waste due to welding errors.

[0004] According to the technical solution provided by the utility model, the visual error-proofing device for gas shielded welding of a conjoined turbine shell comprises an external connection base plate, a camera connection bracket, an industrial camera, a camera lens, a connection bracket, a light source connection flange and a light source;

[0005] A camera connecting bracket is fixed on the external extension connecting base plate, an industrial camera and a connecting bracket are fixed on the camera connecting bracket, the lens mount of the industrial camera is set downward, and a camera lens is installed on the lens mount of the industrial camera. A light source connecting flange is fixed on the lower end of the connecting bracket, and a light source is fixed on the lower surface of the light source connecting flange. The light source is located below the camera lens.

[0006] Preferably, the light source is annular, and the light source and the camera lens are coaxially arranged.

[0007] The use of the utility model can prevent small parts from being installed upside down, installed around or missing during welding, greatly improve the welding quality and reduce material waste caused by welding errors. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0012] A visual error-proofing device for gas shielded welding of a conjoined turbine shell, such as Figure 1 As shown, it includes an external connection base plate 1, a camera connection bracket 2, an industrial camera 3, a camera lens 4, a connection bracket 5, a light source connection flange 6 and a light source 7;

[0013] A camera connecting bracket 2 is fixed on the outward extension connecting base plate 1, an industrial camera 3 and a connecting bracket 5 are fixed on the camera connecting bracket 2, the lens mount of the industrial camera 3 is set downward, a camera lens 4 is installed on the lens mount of the industrial camera 3, a light source connecting flange 6 is fixed on the lower end of the connecting bracket 5, a light source 7 is fixed on the lower surface of the light source connecting flange 6, and the light source 7 is located below the camera lens 4.

[0014] The light source 7 is annular in shape, and is coaxially arranged with the camera lens 4 .

[0015] like Figure 2 As shown, when the utility model is installed, one end of the outward extension connecting base plate 1 is fixed on the flange connecting block 8, and an openable and adjustable wire feeding mechanism 9 is installed at the lower end of the flange connecting block 8, and a welding wire feeding protective cover 10 is provided between the flange connecting block 8 and the wire feeding mechanism 9, and a welding gun 11 is installed at the lower end of the wire feeding mechanism 9, and a protective leather cover 12 is provided between the welding gun 11 and the wire feeding mechanism 9, and the flange connecting block 8 is connected to the sixth axis connecting flange of the welding robot 13.

[0016] like Figure 3 As shown, during operation, the welding robot 13 moves to the position of the one-piece turbine shell to be welded, so that the light source 7 is located above the one-piece turbine shell to be welded. After the industrial camera 3 takes a picture of the one-piece turbine shell to be welded, the picture will be displayed on the visual monitoring display. The monitoring personnel can judge whether the small parts are installed upside down, installed around or missing through the display content on the visual monitoring display. When the monitoring personnel judge that the small parts are installed correctly through the display content on the visual monitoring display, the welding gun 11 performs welding to weld the one-piece turbine shell and the small parts into one.

[0017] The use of the utility model can prevent small parts from being installed upside down, installed around or missing during welding, greatly improve the welding quality and reduce material waste caused by welding errors.

[0018] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to examples, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
