Description

Technical Field

[0001] The invention relates to the technical field of enamel stirrer calibration, in particular to a verticality calibration and adjustment device for an enamel stirrer. Background Art

[0002] The enameled stirring shaft is a composite material made by lining the outer surface of a carbon steel shaft with glass containing high silicon dioxide, which is firmly adhered to the metal surface through high temperature burning.

[0003] The conventional method for vertical calibration of enameled stirrers is visual inspection. This involves visually inspecting the angle between the enameled stirrer and the horizontal to determine verticality, but this approach is inaccurate. Flame heating is then used to heat and soften a portion of the fixed enameled stirrer shaft. However, this heating adjustment is inefficient, and the enameled stirrer, after vertical calibration and adjustment, cannot meet the high-precision requirements of large-scale equipment. Summary of the Invention

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] The following is combined with Figure 1-3 The present invention will be further described:

[0021] A verticality calibration and adjustment device for an enamel stirrer comprises a platform 1, wherein a clamping and rotating device 2 and a height-adjustable lifting device 7 are respectively provided on both sides of the top of the platform 1, wherein the clamping and rotating device 2 comprises a motor housing 21, wherein a transmission seat 22 is fixedly provided on the top of the motor housing 21, wherein a main shaft tube 23 is rotatably provided in the transmission seat 22, wherein a motor for driving the main shaft tube 23 to rotate is provided in the motor housing 21, and both ends of the main shaft tube 23 are connected with a chuck 25 through a bearing seat 24, and the lifting device 7 comprises a column 71, wherein a nut seat 72 is fixedly provided on the top of the column 71, wherein a screw 73 threadedly connected to the nut seat 72 is rotatably provided in the nut seat 72, and a lifting seat 74 is rotatably provided on the top of the screw 73, and two roller seats 77 are symmetrically provided on the top of the lifting seat 74, wherein a roller 75 is rotatably provided on the roller seat 77, and an adjusting wrench 76 threadedly connected to the screw 73 is provided between the nut seat 72 and the lifting seat 74.

[0022] In this embodiment, chucks 25 are connected to both ends of the spindle tube 23 via bearing blocks 24. The two chucks 25 clamp one end of the enamel stirrer 10, facilitating the fixed rotation of the enamel stirrer 10 and measuring the verticality of the bottom and ends of the enamel stirrer 10. The bearing blocks 24 are used to control the coaxiality of the two chucks 25 and the spindle tube 23. A motor is provided within the motor housing 21 to drive the spindle tube 23. Using a motor to drive the spindle tube 23 is a common technique, and the specific structure is not described in detail here.

[0023] The lifting device 7 is used to support the other end of the enameled stirrer 10. Two rollers 75 work together to hold the enameled stirrer 10 above and above the stirrer 10. The rollers 75 rotate with the rotation of the enameled stirrer 10. The height of the rollers 75 is adjusted by turning the screw 73 threadedly connected to the nut seat 72, ensuring that the two ends of the enameled stirrer 10 are coaxially arranged. Once the height of the rollers 75 is determined, the adjustment wrench 7 is turned to contact the nut seat 72, preventing the screw 73 from rotating further and locking the height of the rollers 75.

[0024] A heating device 3 and a calibration device 8 are provided on the platform 1 between the clamping and rotating device 2 and the lifting device 7. The heating device 3 is fixedly arranged on the top of the lifting device 4. The heating device 3 includes an insulation box 31. A furnace core 32 is provided in the middle of the insulation box 31. Resistance wires 34 are provided in the cavities of the inner and outer walls of the furnace core 32. A plurality of heating grooves 33 are provided on the inner wall of the furnace core 32. Insulation material is filled between the insulation box 31 and the outer wall of the furnace core 32.

[0025] In this embodiment, the furnace core 32 is preferably made of silicon carbide, which has the characteristics of corrosion resistance, high temperature resistance, high strength, good thermal conductivity, and impact resistance. It can withstand temperatures of 1500 degrees Celsius and is not easily damaged during long-term use. The side walls of the insulation box 31 are made of aluminum silicate ceramic plates, which can withstand temperatures of 1360 degrees Celsius and provide excellent thermal insulation. The insulation material is preferably aluminum silicate ceramic fiber felt, which has excellent thermal insulation effect and can maintain a constant temperature of approximately 1050 degrees Celsius for a long time after heating.

[0026] A moving wheel 5 is provided at the bottom of the lifting device 4. The lifting device 4 includes a bottom plate 41 and a top plate 42. A scissor-type lifting frame 43 is hinged between the bottom plate 41 and the top plate 42. A lifting rod 44 is hinged between the scissor-type lifting frame 43 and the bottom plate 41. A foot switch 45 electrically connected to the lifting rod 44 is provided on the bottom plate 41. The insulation box body 31 is fixedly set on the top of the top plate 42. The moving wheel 5 is set at the bottom of the bottom plate 41. A moving wheel locking piece 6 is provided on the moving wheel 5. A walking handle 9 is provided on the bottom plate 41.

[0027] In this embodiment, the lifting device 4 is used to adjust the height of the heating device 3, allowing the furnace core 32 to be adjusted to a suitable height to facilitate heating of the enamel stirrer 10. During operation, the lifting rod 44 is first extended and retracted using the foot switch 45. The height of the top plate 42 is then adjusted to align the furnace core 32 with the spindle tube 23. The enamel stirrer 10 is then passed through the furnace core 32, with one end of the enamel stirrer 10 being clamped and secured by the two chucks 25, while the other end of the enamel stirrer 10 is lifted above the two rollers 75.

[0028] The calibration device 8 is movably arranged on the top of the platform 1. The calibration device 8 includes a measuring platform 81. The measuring platform 81 is movably arranged on the top of the platform 1. An adjustment meter seat 82 is provided on the top of the measuring platform 81. A runout meter 83 is provided on the adjustment meter seat 82.

[0029] In this embodiment, a measuring platform 81 is placed on platform 1 to the side of the enameled stirrer 10 at the measurement location. The gauge base 82 is adjusted to bring the runout gauge 83 into contact with the sidewall of the enameled stirrer 10. The motor then drives the spindle tube 23 to rotate the enameled stirrer 10, and the runout gauge 83 is used to check the verticality of the enameled stirrer 10. If the verticality of the enameled stirrer 10 at the measurement location exceeds the detection range, the measuring platform 81 is removed, and the heat-insulating box 31 is moved to the relevant position of the enameled stirrer 10 via the moving wheels 5. The resistance wire 34 is then energized to heat and soften the rotating enameled stirrer 10.
