The moving plate 10 is driven by the air cylinder 9 to move on one side of the connecting plate 6.

[0029] Two sliding plates 13 and a push plate 12 are slidably arranged on the top surface of each moving plate 10. The push plate 12 is located at the same end of the two sliding plates 13, and the end of each sliding plate 13 is in sliding cooperation with the push plate 12. The push plate 12 will push the sliding plate 13 to slide when sliding.

[0030] The two ends of the push plate 12 near the sliding plate 13 are provided with inclined surfaces, and the end of the sliding plate 13 near the push plate 12 is provided with an inclined surface.

The two sliding plates 13 are symmetrical about the middle part of the moving plate 10. The sliding direction of the sliding plate 13 is perpendicular to the sliding direction of the push plate 12, and the sliding direction of the sliding plate 13 is consistent with the moving direction of the moving plate 10. When the moving plate 10 moves, the abutting rod 15 at the end of the sliding plate 13 will abut and fix the hanging seat.

[0034] Working principle:

[0035] The bottom plate 1 is fixed on the numerical control machine tool by screws, and the hanging seat for moving the subway is moved to the top of the two supporting rods 7, so that the two positioning columns 8 pass through the holes on the hanging seat.

[0036] The hanging seat is located between the two horizontal plates on one side of the support plate 2, and the hanging seat is located between the two moving plates 10.

[0037] First, rotate the bolt 4 on the bottom horizontal plate, so that the bolt 4 rotates in the threaded hole 3. While rotating, the abutting plate 5 will be pushed upward, until the abutting plate 5 is located on the bottom surface of the hanging seat, supporting the bottom of the hanging seat.

[0038] The cylinder 9 is started, and the output end of the cylinder 9 pushes the moving plate 10, drives the push plate 12, the sliding plate 13 and the abutting rod 15 to move to one side of the hanger seat, and until the abutting rod 15 abuts on the side of the hanger seat, the hanger seat is fixed.

[0039] If the shape of the side of the hanger seat is irregular, when the moving plate 10 moves, one of the abutting rods 15 will contact the side of the hanger seat.

[0040] Then the cylinder 9 continues to push the moving plate 10 to move, and one of the abutting rods 15 cannot move due to the obstruction of the hanger seat, so the sliding plate 13 connected with the abutting rod 15 cannot move. At this time, the moving plate 10 will slide on the sliding plate 13 which cannot move.

[0041] The moving plate 10 will continue to drive the push plate 12 to move, and the sliding plate 13 which cannot move will press the push plate 12, so that the push plate 12 slides to the other sliding plate 13. Therefore, the push plate 12 will press the other sliding plate 13, so that the other sliding plate 13 slides out of the moving plate 10. Until the abutting rod 15 at the end of the other sliding plate 13 abuts on the hanger seat.

[0042] The bolt 4 on the top horizontal plate is rotated, and the bolt 4 is rotated in the threaded hole 3. While the bolt 4 is rotated, the abutting plate 5 is pushed downward, until the abutting plate 5 contacts the hanger seat. The hanger seat is fixed, so that the hanger seat is machined by numerical control in the subsequent process.

[0043] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
