DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] like Figure 1 , 2 As shown, a device for simultaneously cutting support plate holes on multiple casing workpieces includes a base 1 with a base plate 101 and an adapter plate 2 installed on the base plate 101. The base plate 101 has a circular hole 1011 in the center, and the bottom surface of the adapter plate 2 has an axial cone 204 protruding downward. The axial cone 204 is located in the circular hole 1011, so that the adapter plate 2 can rotate around its own axial cone 204 on the base plate 101. The adapter plate 2 is sleeved with multiple concentric annular mounting positions for mounting various types of workpieces. When used, multiple concentric annular workpieces with different diameters and the same support plate installed through are placed on the corresponding annular mounting positions of the adapter plate 2, and their respective angular directions are adjusted, and then the adapter plate 2 is rotated to conform to the cutting direction of the wire cutting, and the support plate holes are cut on multiple workpieces at the same time. In this way, multiple workpieces can be cut at the same time, and it can be ensured that the cutting holes on each workpiece have uniform specifications.

[0020] Furthermore, the height of the axial cone 204 is less than or equal to the depth of the circular hole 1011, and a threaded hole is provided at the center of the axial cone 204. A bolt 3 with a bolt handle radius larger than the radius of the circular hole 1011 is used to fix the adapter plate 2 to the base plate 101 through the threaded hole.

[0021] A threaded hole is provided on the base plate 101, and a positioning hole corresponding to the threaded hole is provided on the adapter plate 2. A positioning pin 4 with an external thread is screwed into the threaded hole and inserted into the positioning hole to position the adapter plate 2 to prevent the adapter plate 2 from rotating.

[0022] The base 1 also has a seat plate 102. The base plate 101 is tilted and integrally connected to the seat plate 102 at an angle, so that the workpiece maintains a posture that conforms to the cutting direction.

[0023] The annular mounting position includes an annular mounting position 1 201, annular mounting position 202 and annular mounting position 3 203 from the inside to the outside. Of course, the mounting positions can also be increased or decreased as needed.
