The support plate and the fixing plate are arranged at intervals from top to bottom inside the fixing cylinder, and both the support plate and the fixing plate are fixedly connected to the fixing cylinder. The center of the support plate is provided with a first through hole for the spindle mold to pass through.

[0006] All of the clamping mechanisms are evenly distributed circumferentially within the fixed cylinder;

[0007] The clamping mechanism includes a clamping plate and a reset mechanism. The clamping plate includes a support portion, a connecting portion, and an inclined plate portion connected in sequence. The support portion supports the bottom surface of the ingot mold, and the end of the inclined plate portion away from the connecting portion abuts against the outer wall of the ingot mold. The support plate is provided with a second through hole corresponding to the clamping plate, and the clamping plate passes through the second through hole. The connecting portion is rotatably engaged with the support plate through a horizontal rotating shaft, and the axial direction of the rotating shaft is tangent to the circumferential direction of the fixed cylinder. The clamping plate can swing within the second through hole.

[0008] The reset mechanism includes a moving rod, a spring, a reset block, and a limiting plate. A third through hole is provided on the fixed plate corresponding to the moving rod, and the moving rod slides in conjunction with the third through hole. The limiting plate is fixed to the bottom of the moving rod, and the diameter of the limiting plate is larger than the diameter of the third through hole. The reset block is fixed to the top of the moving rod, and a roller is installed on the top of the reset block. The roller is used to roll in conjunction with the bottom end of the support part in the same clamping mechanism. The spring is sleeved on the moving rod, with one end of the spring abutting against the bottom end of the reset block and the other end abutting against the fixed plate.

[0009] Preferably, the clamping plate is integrally formed.

[0010] Preferably, it further includes at least two auxiliary fixing mechanisms evenly distributed along the circumference of the fixed cylinder. The auxiliary fixing mechanism includes an electric telescopic rod fixed on the fixed cylinder and an arc-shaped plate fixed to the free end of the electric telescopic rod. The arc-shaped plate is located inside the fixed cylinder, and the inner arc surface of the arc-shaped plate can fit against the outer wall of the ingot mold.

[0011] Preferably, there are two auxiliary fixing mechanisms.

[0012] Preferably, the clamping mechanism further includes a limiting component;

[0013] The limiting assembly includes an abutment block, a threaded rod, and a handle. The threaded rod is threaded into the side wall of the fixed cylinder, and the axial direction of the threaded rod is perpendicular to the side wall of the fixed cylinder. The handle is fixedly connected to one end of the threaded rod outside the fixed cylinder, and the other end of the threaded rod is rotatably connected to the abutment block. The top end of the abutment block is slidably engaged with the support plate, and the bottom end of the abutment block is slidably engaged with the fixed plate. The clamping plate can abut against the side wall of the abutment block.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The purpose of this invention is to provide a centering device for fixing an ingot mold, so as to solve the problems existing in the prior art, so that the ingot mold can be fixed during the casting process, thereby improving the safety of the casting process.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1-6 As shown, this embodiment provides a centering device for fixing a spindle mold, including a fixing cylinder 1, a support plate 2, a fixing plate 3, four clamping mechanisms and two auxiliary fixing mechanisms.

[0033] In this embodiment, the axis of the fixed cylinder 1 is vertical, and the support plate 2 and the fixed plate 3 are arranged at intervals from top to bottom inside the fixed cylinder 1. Both the support plate 2 and the fixed plate 3 are fixedly connected to the fixed cylinder 1. In this embodiment, all edges of the support plate 2 and all edges of the fixed plate 3 are fixedly connected to the inner wall of the fixed cylinder 1. The center of the support plate 2 is provided with a first through hole 4 for the ingot mold 22 to pass through. Obviously, the diameter of the first through hole 4 needs to be larger than the diameter of the ingot mold 22 to ensure that the ingot mold 22 can pass through the first through hole 4.

[0034] All clamping mechanisms are evenly distributed circumferentially within the fixed cylinder 1. Each clamping mechanism includes a clamping plate 6, a reset mechanism, and a limiting component. The clamping plate 6 includes a support portion 601, a connecting portion 602, and an inclined plate portion 603 connected in sequence. The support portion 601 supports the bottom surface of the ingot mold 22, and the end of the inclined plate portion 603 away from the connecting portion 602 abuts against the outer wall of the ingot mold 22. The support plate 2 is provided with a second through hole 5 corresponding to the clamping plate 6. The clamping plate 6 passes through the second through hole 5. The connecting portion 602 is rotatably engaged with the support plate 2 via a horizontal rotating shaft, and the axial direction of the rotating shaft is tangent to the circumferential direction of the fixed cylinder 1. The clamping plate 6 can swing within the second through hole 5. In this embodiment, the clamping plate 6 is integrally formed.

[0035] It should be noted that the specific shape of the clamping plate 6 needs to meet the following requirements: when the end of the inclined plate portion 603 away from the connecting portion 602 abuts against the outer wall of the ingot mold 22, the supporting portion 601 can still support the bottom surface of the ingot mold 22; while when the top of the supporting portion 601 contacts the bottom surface of the ingot mold 22, the inclined plate portion 603 may not necessarily abut against the outer wall of the ingot mold 22.

[0036] The reset mechanism includes a moving rod 12, a spring 15, a reset block 14, and a limiting plate 13. A third through hole is provided on the fixed plate 3 corresponding to the moving rod 12, and the moving rod 12 slides in the third through hole. The limiting plate 13 is fixed to the bottom of the moving rod 12, and the diameter of the limiting plate 13 is larger than the diameter of the third through hole. The reset block 14 is fixed to the top of the moving rod 12, and a roller 16 is installed on the top of the reset block 14. The roller 16 is used to roll in contact with the bottom end of the support part 601 in the same clamping mechanism. The spring 15 is sleeved on the moving rod 12, with one end of the spring 15 abutting against the bottom end of the reset block 14 and the other end abutting against the fixed plate 3.

[0037] The spring force of spring 15 is greater than the weight of clamping plate 6 and less than the weight of ingot mold 22. Spring 15 is used to cooperate with reset block 14 to always be in contact with clamping plate 6. When ingot mold 22 is removed from clamping plate 6, the spring force of spring 15 pushes reset block 14 to move upward, and at the same time drives roller 16 to roll at the bottom of clamping plate 6, thereby driving clamping plate 6 to rotate, and then returning clamping plate 6 to its original position, which is convenient for the next placement of ingot mold 22.

[0038] The limiting assembly includes an abutment block 7, a threaded rod 8, and a handle 9. The threaded rod 8 is threadedly engaged with the side wall of the fixed cylinder 1, and the axial direction of the threaded rod 8 is perpendicular to the side wall of the fixed cylinder 1. The handle 9 is fixedly connected to one end of the threaded rod 8 located outside the fixed cylinder 1, and the other end of the threaded rod 8 is rotatably connected to the abutment block 7. The top end of the abutment block 7 is slidably engaged with the support plate 2, and the bottom end of the abutment block 7 is slidably engaged with the fixed plate 3. The clamping plate 6 can abut against the side wall of the abutment block 7. When the clamping plate 6 abuts against the abutment block 7, the clamping plate 6 can no longer rotate. Therefore, the abutment block 7 limits the clamping plate 6 and can prevent the clamping plate 6 from rotating too much.

[0039] A slider 11 is fixedly installed at the top and bottom of the abutment block 7. A groove 10 is provided on the bottom surface of the support plate 2 corresponding to the slider 11 at the top of the abutment block 7. A groove 10 is provided on the top surface of the fixed plate 3 corresponding to the slider 11 at the bottom of the abutment block 7. The slider 11 slides in cooperation with the corresponding groove 10. The sliding cooperation between the slider 11 and the groove 10 enhances the stability of the abutment block 7 during movement.

[0040] Two auxiliary fixing mechanisms are evenly distributed along the circumference of the fixing cylinder 1; each auxiliary fixing mechanism includes an electric telescopic rod 19 fixed on the fixing cylinder 1 and an arc plate 20 fixed to the free end of the electric telescopic rod 19. The arc plate 20 is located inside the fixing cylinder 1, and the inner arc surface of the arc plate 20 can fit against the outer wall of the ingot mold 22.

[0041] In this embodiment, a rubber block is provided on the side of the arc-shaped plate 20 away from the electric telescopic rod 19. By providing the rubber block, the ingot mold 22 can be protected to prevent it from being bumped or damaged during placement. A controller 21 is fixed on the outer wall of the fixed cylinder 1, and all the electric telescopic rods 19 are electrically connected to the controller 21.

[0042] The centering device for fixing the ingot mold in this embodiment also includes an annular mounting plate 17 fixedly sleeved on the bottom end of the fixing cylinder 1. The mounting plate 17 is provided with a plurality of positioning holes 18. By providing positioning holes 18, it is convenient to quickly install and disassemble the equipment.

[0043] The usage process of the centering device for fixing the ingot mold in this embodiment is as follows:

[0044] The ingot mold 22 is placed on the support portion 601 of the clamping plate 6. At the same time, the clamping plate 6 rotates, and the end of the inclined plate portion 603 of the clamping plate 6 away from the connecting portion 602 (i.e., the top of the clamping plate 6) abuts against the outer wall of the ingot mold 22. Meanwhile, the bottom end of the support portion 601 of the clamping plate 6 rolls with the roller 16, thereby pushing the reset block 14 downward and compressing the spring 15. After the ingot mold 22 is placed stably, the threaded rod 8 is rotated by the handle 9, thereby driving the abutment block 7 to move. At the same time, the slider 11 slides on the inner wall of the slide groove 10. When the abutment block 7 abuts against the clamping plate 6, the rotation of the threaded rod 8 is stopped. Then, the electric telescopic rod 19 is activated by the controller 21, thereby driving the arc plate 20 to move through the piston rod, so that the arc plate 20 abuts against the outer wall of the ingot mold 22, thus completing the centering operation.
