[0031] See also Figure 1-6 The present invention provides a technical solution: a high-precision arc instrument calibration device for a continuous casting machine, comprising a base 1, a calibration component, a dust removal component and an expansion component, wherein two bracket legs 4 are welded to the upper end of the base 1;

[0032] The calibration component is arranged on the base 1, and the calibration component includes a plurality of adjustment knobs 2, a circular level 3, two connecting members 6, two knobs 1 7, two springs 8, two knobs 2 9, two guide rods 10, two disc members 11, a bracket 12, an upper calibration roller 13, a lower calibration roller 14 and two limit members 23. The circular level 3 is installed on the base 1, and the plurality of adjustment knobs 2 are all installed on the base 1. The lower calibration roller 14 is a roller and two fixing members, and the two fixing members are respectively rotatably connected with the two ends of the corresponding lower calibration roller 14, and the two fixing members are respectively fixed on the corresponding bracket legs 4. The two connecting members 6 slide along the two ends of the corresponding bracket 12, and the two ends of the two upper calibration rollers 13 rotate at the two ends of the corresponding connecting member 6.

[0033] The dust removal assembly is arranged inside the base 1, and the dust removal assembly includes an air cylinder 15, a piston push plate 16, an air pipe 17 and a piston rod 18. The upper end of the air cylinder 15 is fixed inside the base 1, and the piston push plate 16 slides along the inside of the air cylinder 15. The piston rod 18 is fixed on the piston push plate 16. The air pipe 17 is welded to the air cylinder 15. The air pipe 17 faces the four sides of the base 1, and the air pipe 17 is connected to the air cylinder 15. There are four dust removal assemblies, and the four dust removal assemblies are respectively arranged on the four sides inside the base 1.

[0034] The extension component is arranged on the bracket leg 4, and the extension component includes an extension part 5, a slot 19, a strip clip 1 20, a slot 21 and a strip clip 22. The strip clip 22 is welded to the upper end of the bracket leg 4, the slot 21 is opened on the extension part 5, and the strip clip 22 is stuck inside the slot 21. There are two extension components, and the two extension components are respectively arranged on the corresponding bracket legs 4.

[0035] The two strip-shaped clamping members 20 are respectively welded on the upper ends of the corresponding extension members 5 , the two clamping slots 19 are respectively opened at the two ends of the corresponding bracket 12 , and the two strip-shaped clamping members 20 are respectively clamped inside the corresponding clamping slots 19 .

[0036] The two knobs 7 are respectively threadedly connected to the surfaces of the corresponding connecting members 6 , and the surfaces of the two knobs 7 are in contact with the surface of the bracket 12 .

[0037] The upper ends of the two springs 8 are welded to the lower ends of the limiting members 23 , and the lower ends of the two springs 8 are welded to the corresponding connecting members 6 .

[0038] The two guide rods 10 are respectively welded to the upper ends of the corresponding connecting members 6 , and the two limit members 23 slide along the corresponding guide rods 10 .

[0039] The two stoppers 23 both slide along the bracket 12 , and the two disc members 11 are respectively welded to the upper ends of the corresponding guide rods 10 .

[0040] The surfaces of the two rotating knobs 9 are respectively threadedly connected to the surfaces of the corresponding limiting members 23 , and the surfaces of the two rotating knobs 9 are in contact with the surface of the bracket 12 .

[0041] It should be noted that: in the initial state, both springs 8 are in a compressed state.

[0042] When it is necessary to calibrate parts on the continuous casting machine;

[0043] First, the four piston rods 18 are driven to move by external force, and the movement of the four piston rods 18 drives the corresponding piston push plates 16 to move respectively, driving the outside air to enter the interior of the air cylinder 15 through the air pipe 17. Then, the base 1 is driven to move by external force, and the movement of the base 1 drives the four piston rods 18 to move to the factory floor and move relative to each other on the factory floor. The relative movement of the four piston rods 18 drives the corresponding piston push plates 16 to move the internal air of the air cylinder 15 through the four air pipes 17 to blow the dust at the lower end of the base 1 away from the lower end of the air pipe 17.

[0044] Secondly, the circular level 3 is adjusted by adjusting a plurality of adjustment knobs 2 .

[0045] Finally, the base 1 is driven to move by an external force, and the movement of the base 1 drives the lower calibration roller 14 to move until it contacts the lower end of the continuous casting machine component to be calibrated. Subsequently, the two knobs 1 7 and the two knobs 2 9 are driven by an external force to move to loosen the corresponding connecting parts 6 and the limit members 23. Subsequently, after the limit members 23 and the connecting parts 6 are driven to move to appropriate positions by an external force, the two knobs 2 9 are driven by an external force to tighten the positional relationship between the limit members 23 and the bracket 12. Subsequently, the two springs 8 are reset to drive the corresponding connecting parts 6 to move downward. The downward movement of the two connecting parts 6 drives the upper calibration roller 13 to move downward to squeeze the upper end of the continuous casting machine component to be calibrated. When the lowermost side of the upper calibration roller 13 contacts the upper end of the continuous casting machine component to be calibrated, the two knobs 1 7 are driven by an external force to move to tighten the positional relationship between the two connecting parts 6 and the bracket 12. Finally, the indication of the circular level 3 is observed.

[0046] When it is necessary to expand the calibration kit to measure the maximum size of continuous casting machine components;

[0047] First, the two extension pieces 5 are driven to move by external force, and the movement of the two extension pieces 5 drives the corresponding card slots 21 to move to the surface of the corresponding strip card piece 22. Then, the bracket 12 is driven to move by external force, and the movement of the bracket 12 drives the two card slots 19 to move and get stuck on the corresponding strip card piece 20.

[0048] By setting two springs 8 in the calibration assembly, the two springs 8 can be reset to drive the upper calibration roller 13 to move downward to automatically squeeze the part to be calibrated. Subsequently, the calibration step only needs to adjust the position of the upper calibration roller 13. There is no need to worry about the upper calibration roller 13 having insufficient squeezing force or being unstable for the part to be calibrated, thereby reducing the difficulty of calibration.

[0049] Since there is a lot of dust inside the factory, in order to ensure that the base 1 can accurately contact the ground when initializing the value of the circular level 3 in the initial state, a dust removal component is set. The four air pipes 17 in the dust removal component can blow air to blow away the dust at the lower end of the base 1, thereby preventing the dust on the factory floor from affecting the value of the initialized circular level 3.

[0050] Since the components of the continuous casting machine to be calibrated have different sizes, some of the components of the continuous casting machine are larger in size. In order to ensure that the calibration component can be calibrated stably, an extension component is set up, and the extension component can be assembled according to needs, thereby avoiding the problem of limited clamping range during calibration of the calibration component, resulting in the inability to calibrate, that is, expanding the scope of application of the calibration component.

[0051] Working principle:

[0052] When it is necessary to calibrate parts on the continuous casting machine;

[0053] First, the four piston rods 18 are driven to move by external force, and the movement of the four piston rods 18 drives the corresponding piston push plates 16 to move respectively, driving the outside air to enter the interior of the air cylinder 15 through the air pipe 17. Then, the base 1 is driven to move by external force, and the movement of the base 1 drives the four piston rods 18 to move to the factory floor and move relative to each other on the factory floor. The relative movement of the four piston rods 18 drives the corresponding piston push plates 16 to move the internal air of the air cylinder 15 through the four air pipes 17 to blow the dust at the lower end of the base 1 away from the lower end of the air pipe 17.

[0054] Secondly, the circular level 3 is adjusted by adjusting a plurality of adjustment knobs 2 .

[0055] Finally, the base 1 is driven to move by an external force, and the movement of the base 1 drives the lower calibration roller 14 to move until it contacts the lower end of the continuous casting machine component to be calibrated. Subsequently, the two knobs 1 7 and the two knobs 2 9 are driven by an external force to move to loosen the corresponding connecting parts 6 and the limit members 23. Subsequently, after the limit members 23 and the connecting parts 6 are driven to move to appropriate positions by an external force, the two knobs 2 9 are driven by an external force to tighten the positional relationship between the limit members 23 and the bracket 12. Subsequently, the two springs 8 are reset to drive the corresponding connecting parts 6 to move downward. The downward movement of the two connecting parts 6 drives the upper calibration roller 13 to move downward to squeeze the upper end of the continuous casting machine component to be calibrated. When the lowermost side of the upper calibration roller 13 contacts the upper end of the continuous casting machine component to be calibrated, the two knobs 1 7 are driven by an external force to move to tighten the positional relationship between the two connecting parts 6 and the bracket 12. Finally, the indication of the circular level 3 is observed.

[0056] When it is necessary to expand the calibration kit to measure the maximum size of continuous casting machine components;

[0057] First, the two extension pieces 5 are driven to move by external force, and the movement of the two extension pieces 5 drives the corresponding card slots 21 to move to the surface of the corresponding strip card piece 22. Then, the bracket 12 is driven to move by external force, and the movement of the bracket 12 drives the two card slots 19 to move and get stuck on the corresponding strip card piece 20.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
