[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1, by Figures 1-4 The present invention includes a support sleeve 1, a support column 2 connected to the center of the support sleeve 1, a turntable 3 rotatably connected to the upper end of the support column 2, a support plate 5 connected to the upper end of the turntable 3 via a support rod 4, a workpiece table 6 provided in the middle of the upper end of the support plate 5, slide rails 7 symmetrically connected to both sides of the workpiece table 6 and located at the upper end of the support plate 5, a first movable plate 8 and a second movable plate 9 symmetrically provided on the outside of the slide rails 7, and sliders 10 connected to the lower ends of the first movable plate 8 and the second movable plate 9, the sliders 10 slidingly engaging with the slide rails 7.

[0023] The upper middle part of the first movable plate 8 and the second movable plate 9 are both connected to the fixed seat 11. The two fixed seats 11 are provided with T-slots 12 on opposite sides. T-blocks 13 are movably provided inside the T-slots 12. One end of the T-block 13 is connected to the clamping block 14. The end of the T-block 13 away from the clamping block 14 is provided with a threaded hole 15. A locking knob 16 is provided through the outside of the fixed seat 11. The screw section of the locking knob 16 is threadedly connected to the threaded hole 15.

[0024] The structure of locking the T-block 13 into the T-slot 12 by locking the knob 16 allows the clamping block 14 to be replaced with a matching clamping block 14 according to the shape of the casting.

[0025] Both sides of the lower end of the first movable plate 8 are fitted with external racks 17. Both sides of the lower end of the second movable plate 9 are provided with external rack grooves 18 corresponding to the two external racks 17. The external racks 17 are located in the external rack grooves 18. Both sides of the lower end of the second movable plate 9 are fitted with internal racks 19. Both sides of the lower end of the first movable plate 8 are provided with internal rack grooves 20 corresponding to the two internal racks 19. The internal racks 19 are located in the internal rack grooves 20.

[0026] A transmission gear 21 is provided between the outer rack 17 and the inner rack 19, and the transmission gear 21 is rotatably connected to the support plate 5 through the connecting shaft 22.

[0027] A fixing plate 23 is connected to the middle of one side of the support plate 5. An adjusting screw 24 is connected to the internal thread of the fixing plate 23. One end of the adjusting screw 24 is rotatably connected to the side wall of the first movable plate 8. A wing nut 25 for locking is sleeved on the external thread of the adjusting screw 24.

[0028] By rotating the adjusting screw 24, the first movable plate 8 is moved towards the second movable plate 9, and then the outer rack 17 meshes with the transmission gear 21 for transmission. Then the transmission gear 21 meshes with the inner rack 19 for transmission, so that the second movable plate 9 moves towards the first movable plate 8 at the same time, and then the clamping blocks 14 on both sides move closer to each other to clamp the casting. After clamping and adjusting, the wing nut 25 is tightened to lock it.

[0029] Conversely, when the adjusting screw 24 is rotated, the first movable plate 8 moves away from the second movable plate 9, the clamping blocks 14 on both sides move away from each other so as to release the casting.

[0030] The lower end of the turntable 3 is connected to an internal gear ring 26. A motor 27 is installed inside the support sleeve 1. The output end of the motor 27 is connected to a drive gear 28. The drive gear 28 meshes with the internal gear ring 26. The motor 27 drives the drive gear 28 to rotate, which in turn drives the internal gear ring 26 to mesh and transmit power, so that the internal gear ring 26 drives the turntable 3 to rotate, so as to adjust the casting to different angles for easy processing.

[0031] Working principle:

[0032] In use, first select a suitable clamping block 14 according to the shape and size of the casting, and assemble the clamping block 14 with the T-slot 12 through the T-block 13. By rotating the locking knob 16, the T-block 13 is fixed in the T-slot 12 of the fixing seat 11, thereby realizing the installation and fixation of the clamping block 14. This design allows the clamping block 14 to be replaced according to castings of different shapes, improving the versatility and applicability of the device.

[0033] Then, the casting to be processed is placed on the workpiece table 6. By rotating the adjusting screw 24, the first movable plate 8 is moved towards the second movable plate 9. Since the lower ends of the first movable plate 8 are fitted with external racks 17 on both sides, and the lower ends of the second movable plate 9 are fitted with internal racks 19 on both sides, and a transmission gear 21 is provided between the external racks 17 and the internal racks 19, the transmission gear 21 is rotatably connected to the support plate 5 through the connecting shaft 22. Therefore, when the first movable plate 8 moves, the external racks 17 mesh with the transmission gear 21, and the transmission gear 21 meshes with the internal racks 19, so that the second movable plate 9 also moves towards the first movable plate 8.

[0034] As the first movable plate 8 and the second movable plate 9 approach each other, the clamping blocks 14 on both sides gradually clamp the casting and apply clamping force to ensure that the casting remains stable during processing. After clamping, tighten the wing nut 25 and lock the adjusting screw 24 to prevent the position of the clamping block 14 from loosening during processing.

[0035] During the casting process, if it is necessary to adjust the angle of the casting in order to perform multi-directional machining operations;

[0036] First, start the motor 27 inside the support sleeve 1. The output end of the motor 27 drives the drive gear 28 to rotate. The drive gear 28 meshes with the internal gear ring 26 at the lower end of the turntable 3, thereby causing the turntable 3 to rotate.

[0037] The rotation of the turntable 3 causes the tray 5 and the castings on it to rotate together, thereby realizing the angle adjustment of the castings; by controlling the rotation of the motor 27, the processing angle of the castings can be adjusted to meet different processing needs;

[0038] After processing, the casting needs to be removed from the clamping device. At this time, loosen the wing nut 25, rotate the adjusting screw 24 in the opposite direction, drive the first movable plate 8 away from the second movable plate 9, and move the clamping blocks 14 on both sides away from each other, thereby releasing the casting and completing the entire clamping and processing process.
