Description
Technical Field
The invention relates to a hole measuring tool and a hole measuring method for measuring a center hole, in particular to a hole measuring tool and a hole measuring method for measuring an inner center hole of a special part with a structure, and belongs to the field of steam turbine equipment.
Background
When the center position of the inner hole of the special structural part is determined, the problem that the edge finder cannot contact the edge of the hole due to insufficient length of the infrared probe is often encountered, so that the center position of the hole cannot be determined, and the subsequent machining precision of the relevant part taking the hole center as a reference is directly influenced.
Disclosure of Invention
The invention provides a hole measuring tool and a hole measuring method for measuring an internal center hole of a special structural part, aiming at solving the problem that when the center position of the internal center hole of the special structural part is determined, the infrared probe is often short in length and an edge finder cannot contact the edge of the hole.
The technical scheme adopted by the invention for solving the problems is as follows: the hole measuring tool comprises an upper measuring body and a conical part, wherein the lower end of the upper measuring body is fixedly connected with the upper end of the conical part.
Further, the upper measuring body is a solid cylinder.
Furthermore, the conical part is a frustum body with an outer contour gradually reduced from top to bottom.
The method comprises the following specific steps:
inserting a conical part of a hole measuring tool into a hole of a part to be measured and screwing;
and step two, measuring the circle center position of an upper measuring body of the hole measuring tool by using an infrared probe or numerical control equipment, wherein the circle center position is the hole center position.
Furthermore, in the first step, the hole of the part to be measured and the conical part of the hole measuring tool need to be ensured to be in interference fit.
The invention has the beneficial effects that: the method is simple to operate and high in accuracy. The method is very effective for products of the hole centers which cannot be measured by the infrared probe and the edge finder, and fills up another gap in the hole measuring method; the invention is suitable for any product, can be operated by inexperienced operators, and has strong universality and high practicability.
