The top of the box body 1 is fixed with a shell body 2 by bolts. Both sides of the shell body 2 are fixed with side plates 4 by bolts. The inner thread of the side plate 4 is connected with a threaded rod 5. One end of the threaded rod 5 passes through the side plate 4 and is rotatably connected with a placement plate 6. The threaded rod 5 is rotated to make the placement plate 6 move toward the middle to clamp the heat-resistant steel casting. The bottom of the placement plate 6 is fixed with two cylinders 10 by bolts. One end of the piston rod of the cylinder 10 passes through the placement plate 6 and is rotatably connected with a first connecting rod 11. The upper surface of the placement plate 6 is rotatably connected with There are two second connecting rods 12, and the second connecting rods 12 are rotatably connected to the first connecting rods 11. A rubber ball 14 is bonded to one end of the second connecting rod 12. The cylinder 10 extends to rotate the first connecting rod 11. The connection between the first connecting rod 11 and the second connecting rod 12 is a rotation point, so that the rubber ball 14 moves downward and contacts the upper surface of the heat-resistant steel casting, further fixing the heat-resistant steel casting. The interior of the shell 2 is slidably connected to a collection box 3. Debris generated after punching the heat-resistant steel casting falls into the collection box 3 for collection, which is convenient for cleaning and avoids the debris falling directly onto the workbench and being difficult to clean.

The puncher 7 is fixed to the outer wall of one side of the shell 2 by bolts, and a plurality of universal wheels are fixed to the bottom outer wall of the box body 1 by bolts. When the device needs to be moved, the electric push rod 16 is started, and the electric push rod 16 contracts to cause the connecting plate 17 to drive the sliding rod 18 to move upward, thereby moving the support leg 19 upward until the height of the support leg 19 exceeds the universal wheel, so that the universal wheel contacts the ground, thereby facilitating the staff to move the device.

[0026] Working principle: when it is necessary to drill a hole in the heat-resistant steel casting, first rotate the threaded rod 5 to move the placement plates 6 to the middle, place the heat-resistant steel casting between the two placement plates 6, move the placement plates 6 to a suitable position to clamp the heat-resistant steel casting, and then start the cylinder 10.
