Technical Field

[0001] The utility model relates to the technical field of enameled glass tank body processing, in particular to a hole opening and centering device for a tank cover on an enameled glass tank body. Background Art

[0002] Enameled glass tanks, commonly referred to as glass-lined tanks, are storage containers made of a combination of enamel and glass. They consist of a metal body, a layer of enameled glass attached to the inner surface of the metal, and a lid attached to each end. To relieve internal pressure, facilitate gas exchange and ventilation, and allow for the inflow and outflow of liquids, multiple holes are required in the lid. Typically, workers draw lines to determine the center point of each hole, then use a plasma cutter to cut the hole with the center point as the center.

[0003] With respect to the above-mentioned related technologies, the inventors found that when it is necessary to process holes on a large number of can lids, workers are required to draw lines to find the center points of the holes, which increases labor intensity and reduces work efficiency. In addition, workers are prone to large errors in drawing lines to find the center points of the holes due to manual operation, which reduces the processing position accuracy. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a device for finding the center of a circle of a hole in a tank cover on an enameled glass tank body, which reduces labor intensity and improves work efficiency and position accuracy.

[0006] A positioning rod assembly is provided at the center of the annular body, and a plurality of fixing rods are connected at intervals between the outer circle of the positioning rod assembly and the inner wall of the annular body.

[0007] By adopting the above technical solution, when processing holes on a large number of can lids, according to actual requirements, first, on the first can lid, the worker manually draws lines to find the center points of multiple holes. Secondly, the hole centering device is placed on the outer surface of the can lid. By using the positioning rod assembly, the lower end of the positioning rod assembly is brought into contact with the center of the outer circular top of the can lid. At this time, the arc rod assembly is driven by the arc slider assembly to move to a suitable position in the circumferential direction, and the T-block assembly is operated to slide in the T-slot so that the small diameter end of the tapered tube assembly coincides with the manually found hole center point. , and operate the positioning rod assembly to fix the arc rod assembly relatively to the annulus, repeat the above actions so that the center points of other holes found manually are coincident with the corresponding small-diameter ends of the tapered tube assemblies. Next, place the hole centering device after the tapered tube assembly is fixed relative to the annulus on different tank covers, and only use a marker pen to reach into the hole of the tapered tube assembly and contact the outer surface of the tank body.

[0014] In a preferred example, the present invention can be further configured as follows: the T-shaped block assembly includes a T-shaped block body and a third butterfly bolt spirally inserted into the T-shaped block body.

[0015] By adopting the above technical solution, the T-shaped block body slides in the T-shaped groove, which makes it easy to adjust the tapered tube assembly to coincide with the center point of the corresponding hole, and then rotate the third butterfly bolt to relatively fix the T-shaped block body and the arc rod assembly.

[0016] In a preferred example, the present invention can be further configured as follows: the tapered tube assembly includes a tapered tube body and a strip plate, and the tapered tube body is connected to the T-shaped block assembly via the strip plate.
