Problems solved by technology

[0002] For large and immovable heavy equipment, in the case of wear, deformation, corrosion, etc., it needs to be repaired online in a timely manner. Facing the requirements of short repair period and high processing accuracy, in general, there is no special repair equipment
In the conventional repair process, the disassembled parts are transported to the processing plant by breaking them into parts; or the cutting power heads that need to be used, such as milling power heads, are installed on the mobile workbench like building blocks To repair the workpiece, build a repair bench at the repair site, and place the cutting power head on a movable workbench for processing. This kind of repair solution is time-consuming and labor-intensive, with a long processing cycle, and the processing accuracy cannot be guaranteed. Strong and dangerous

Embodiment 1

[0034]Embodiment 1: The large-scale archway of the four-high rolling mill for repairing and processing medium and heavy plates is 1.4-1.5 meters high and 4.42 meters long. Set up a mattress 17 inside the frame of the rolling mill archway, the mattress 17 is to be placed on the support roller seat surface of the roll changing car in and out, the planer body 1 and the combination platform 4 are installed on the mattress 17, when the in and out car 28 enters In the working span of the rolling mill, the upper part of the column 6 of the special combined machine tool is installed to enter the processing position.

[0035] The assembly process of the combined machine tool is as follows:

[0036] Place mobile planer bed 1 and planer slide table 2 on mattress 17, the bed length is 5 meters, X guide rail 18 and screw mandrel 16 are arranged on bed bed 1, slide table 2 is installed on bed body 1 top, slide table 2. It can move left and right along the guide rail 18. The guide rail 18 i...

Embodiment 2

[0055] Embodiment 2: Repair and process the large archway window of the three-roll rolling mill for medium and heavy plates with a height of 3 meters and a width of 500mm. Place a flat surface 13 inside the frame of the rolling mill archway. The length of the flat plate is 3.6 meters. The column seat and special combined machine tool are installed on the workbench of the movable slide table 27, excluding the bed and the slide table part, the combined machine tool is provided with the feed in the X direction by the 600*3500mm mobile slide table 27, the column, the cross slide, and the milling power The head provides feed and milling power in the Y direction and Z direction. The transmission of the mobile slide table adopts the fast feed motor 29 and the slide table feed motor 30 to supply, and the displacement of the cross slide on the column is controlled by the variable frequency motor 10 on the column top plate.

[0056] The assembly process is as follows: install a 600*350...
