Description

Special gauge for detecting hole diameter of circular hole of upright post of fence

Technical Field

The utility model relates to the field of special detection tools for detecting the aperture of metal products, in particular to a special detection tool for detecting the aperture of a circular hole of a fence upright post.

Background

In the logistics storage industry, 8 round holes are often arranged in the production process of fence upright post products, and the requirement of the later-stage installation rivet nut on the aperture precision is high, so that the allowable tolerance range of the aperture is phi 12+0.05. This requires frequent self-tests during the production process to prevent large amounts of undesirable products from affecting the pore size due to temperature changes, material, mold changes. The traditional detection tool is a vernier caliper, but the vernier caliper is not suitable for a detection mode of batch frequent detection on a production site. The vernier caliper is used for detection, so that the detection is not only troublesome, but also difficult to perform in normal degree under the field environment with poor light, and the eye strength and the carefully degree of a detector are required to be high. Moreover, the measuring error is easy to generate when the vernier caliper is used for frequent detection under the influence of factors such as production field environment (greasy dirt, gray tip, vibration, light) and the like; in addition, the vernier caliper is low in detection efficiency, and meanwhile the problem that detection is inaccurate due to the fact that the capability of an operator to use the vernier caliper is affected is likely to exist.

Disclosure of Invention

The utility model aims to provide a special gauge for detecting the hole diameter of a circular hole of a fence upright post, which ensures that whether the tolerance of the hole diameter of the circular hole reaches the standard or not is measured rapidly and accurately so as to solve the problems in the background art.

In order to achieve the above purpose, the technical scheme adopted is as follows:

the special gauge for detecting the aperture of the circular hole of the upright post of the fence comprises a gauge main body and a through end and a stop end at two ends of the gauge main body, wherein the special gauge is integrally cylindrical, the diameters of the through end and the stop end are smaller than those of the gauge main body, and an annular stop end mark is arranged at a position close to the stop end; the diameter of the end stop is slightly larger than that of the through end; the diameter of the through end and the diameter of the stop end are respectively the upper limit and the lower limit of the allowable tolerance of the aperture of the round hole.

Preferably, the special gauge is formed by processing hard metal materials which are not easy to deform, and the inside of the special gauge is of a hollow cylinder structure.

Preferably, the diameter of the gauge main body is 13mm, the diameter of the through end is 12.01mm, and the diameter of the stop end is 12.04mm.

Detailed Description

The utility model will be further explained and illustrated with reference to the drawings and examples. It should be noted that, based on the embodiments of the present utility model, all other embodiments obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present utility model.

Examples: referring to fig. 1-3, a special gauge for detecting the hole diameter of a circular hole of a fence upright post is formed by processing hard metal materials which are not easy to deform into a whole, wherein the inside of the special gauge is of a hollow structure, the whole gauge is a cylinder and comprises a gauge main body and a through end 2 and a stop end 1 at two ends of the gauge main body, the diameters of the through end 2 and the stop end 1 are smaller than those of the gauge main body, and an annular stop end mark 3 is arranged at a position close to the stop end 1; the diameter of the end stop 1 is slightly larger than that of the through end 2; the diameter of the through end 2 and the diameter of the end stop 1 are respectively the upper limit and the lower limit of the allowable tolerance of the aperture of the round hole. The diameter of the gauge main body is 13mm, the diameter of the through end 2 is 12.01mm, and the diameter of the stop end 1 is 12.04mm.

The operation method of the embodiment comprises the following steps: firstly, the special checking fixture is taken out, the through end 2 is found, the through end 2 is inserted into a round hole of a workpiece to be checked, and then the end stop 1 is inserted into a round hole of a product 4 to be checked. If the tolerance of the round hole is within the allowable range, that is, if the product 4 to be detected is processed to be qualified, the stop end 1 of the special detection tool should not be inserted into the round hole of the product to be detected.

The main body of the special gauge is manufactured by finishing a through end 2 and a stop end 1 of a standard cylindrical metal shell with a certain thickness through a special metal cutting process and then polishing and grinding the through end 2 and the stop end 1. The accuracy control requirement in the processing process is high.

The terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
