Technical Field

The invention relates to the technical field of measuring equipment, in particular to opening gauges and a using method thereof.

Background

In the machining field or job site, there are a large amount of machinery tee bend, machinery cross branch pipe trompil, and the trompil must compound regulation size, consequently need measure the detection to the trompil, and use slide caliper to detect the hole among the prior art, the operation is complicated, and the check-out time is long, and is inefficient, the progress of influence construction or processing that can be very big.

Disclosure of Invention

Therefore, the hole opening gauges and the using method thereof are provided, the measuring tools are simple and convenient, the hole opening size can be confirmed quickly and effectively, the use and the allocation of professional calipers are reduced, a construction unit can carry out quick processing and inspection, and the working efficiency is improved.

The technical scheme includes that the hole-opening gauge comprises a gauge body, the gauge body comprises a head and neck part and a measuring part, the head and neck part comprises an arc-shaped head handle used for holding, a neck stem used for connecting the measuring part is arranged below the handle, the measuring part is connected below a neck rod, the measuring part is divided into at least six layers of measuring tables in a step shape from top to bottom, the length of each layer of measuring table decreases from top to bottom times, a scale groove is arranged on the surface of each layer of measuring table, and scale values representing the length of the layer of measuring table are engraved in the scale groove.

, the stations are respectively from top to bottom a th station, a second station, a third station, a fourth station, a fifth station and a sixth station.

, the length of the measuring table is 81mm, the length of the second measuring table is 76mm, the length of the third measuring table is 64mm, the length of the fourth measuring table is 51mm, the length of the fifth measuring table is 46mm, and the length of the sixth measuring table is 38 mm.

, separating grooves are arranged between each layers of measuring tables.

The opening gauge of the scheme also comprises the following using methods:

s1: the index finger and the middle finger of an operator respectively hook and clamp two ends of a head handle of the gauge, and the thumb presses the middle part of the head handle to form a triangular stable clamping structure;

s2, an operator clamps the gauge body to align the measuring part of the gauge body with the position of the opening of the workpiece to be detected, the corresponding measuring table extends into the opening according to the limit diameter of the opening, the measuring table can extend into the opening and is positioned on diameters passing through the circle center of the opening, the opening is judged to be qualified, the measuring table cannot extend into the opening, the opening is judged to be unqualified, the marking needs to be carried out on the opening every time openings are detected, and then the next openings are detected.

The working principle and the beneficial effects of the scheme are as follows:

through the integration of standard data, make its array in same layouts, according to the trompil size, be trapezoidal array, utilize high accuracy line cutting to carry out size processing, ensure measurement accuracy.

The generated effect is as follows: measuring tool is simple and convenient, and quick effectual affirmation trompil size reduces professional slide caliper's use and outfit, and the construction unit can handle the inspection fast, improves work efficiency.

The gauge solves the problem that the mechanical three-way branch pipe and the mechanical four-way branch pipe on the construction site are not suitable for opening holes. The gauge can enable constructors on a construction site to find whether the size of the opened hole meets the size of the hole required by the mechanical tee joint and the mechanical cross joint in time. Avoid the serious consequence caused by opening wrong holes, rework or pipeline scrap, and bring unnecessary economic loss to customers.

The gauge simplifies the construction operation, saves time, is convenient to carry and has simple and clear use method.
