[0082] The following is for reference. Figures 1 to 24 Here is a brief overview of the entire workflow of this utility model, from loading the pre-assembled workpiece 22 (the steel plates being assembled vary in thickness) on the fixed end 200 to the workpiece 24 (a thin steel plate) on the movable end 300, including clamping, beveling / milling, and welding:

[0083] S1: First, the workpiece 22 is pushed into the roller table 700, and the push plate mechanism 900 pushes the workpiece 22 to the fixed end 200. The upper lifting device 2 and the lower pressing device 4 in the fixed end 200 act simultaneously to clamp the workpiece 22. It should be noted that Figure 20 The steel plate 221 and the steel plate 223 are clamped by different clamping units 100. Since the thicknesses of the two steel plates are different, the heights of the upper lifting devices 2 corresponding to the two steel plates are different under the control of the numerical control system, so as to achieve the purpose of accurately clamping the steel plates;

[0084] S2: Next, the workpiece 24 is pushed into the roller table 700, and the push plate mechanism 900 pushes the workpiece 22 to the movable end 300. The upper lifting device 2 and the lower pressing device 4 in the movable end 300 act simultaneously to clamp the workpiece 24.

[0085] S3: Then, the movable end 300 is driven by the moving cylinder 8 to move along the track beam 800 and stop at the required position. It should be noted that the fixation after the movable end 300 stops is another structure setting, which is not the innovation of the utility model, so it is not introduced here.

[0086] S4: For the part of the workpiece 22 ready to be connected with the workpiece 24, that is, the right side of the steel plate 221, Figure 2 the numerical control system controls the milling unit 501 to work. The milling unit 501 performs milling and thinning on the lower surface of the one side of the steel plate 221 through the thinning blade 55 on the milling cutter 500 (referring to the reference numeral 220 in Figure 22 );

[0087] S5: When the part of the workpiece 22 ready to be connected with the workpiece 24 is in the same thickness (i.e., the thinning is completed), the numerical control system controls the milling unit 501 to work to mill the upper surface of the workpiece 22 and the workpiece 24 to form a welding groove (for welding, referring to the welding groove δ in Figure 22 and Figure 24 );

[0088] S6: The numerical control system controls the moving cylinder 8 to continue pushing the movable end 300 towards the fixed end 200 until the workpiece 22 and the workpiece 24 are in contact.

[0089] S7: The numerical control system controls the welding unit 503 to work to complete the welding of the workpiece 22 and the workpiece 24 at the welding groove generated in step S5.

[0090] S8: Repeat steps S1 to S7.

[0091] It should be noted that in step S4, if the thickness of the steel plate 221 and the thickness of the steel plate 223 and the workpiece 24 are consistent, the step of milling and thinning is not needed.

[0092] It should be noted that in the present embodiment, the milling unit 501 and the welding unit 503 can both move from one end to the other end along the guide rail 201 (see Figure 12 , but only a part of the guide rail is shown) installed on the rack 302 of the fixed end 200, and the milling unit 501 and the welding unit 503 themselves can realize three-axis movement, so as to efficiently complete milling or welding, but these technologies are not the focus of the present application, and therefore will not be described here.

[0093] In addition, it should be noted that in the present embodiment, the rack 302 of the fixed end 200 of the milling and plate welding integrated machine 1000 is also provided with a chip collector (not shown in the figure) at the bottom, so as to collect the chips falling during the milling process in time.

[0094] In the present application, the above structure is provided, which not only facilitates the splicing of plates with consistent thickness (steel plates are only one type of workpiece), but also particularly enables the splicing of plates with different thicknesses. During the splicing of plates with different thicknesses, the structure of the clamping unit in the present application enables different clamping units to accurately clamp plates with different thicknesses. Meanwhile, when plates with different thicknesses located at the fixed end and the movable end are spliced, the structure of the milling cutter in the present application enables the thick plates to be milled first, and then the milling and welding of the welding groove are completed.

[0095] The technical content and technical features of the present application have been disclosed above, but it can be understood that under the creative idea of the present application, those skilled in the art can make various changes and improvements to the above structure, including the combination of the technical features disclosed or claimed herein, and other combinations that obviously include these features. These modifications and / or combinations all fall within the technical field to which the present application relates, and fall within the protection scope of the claims of the present application.
