Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] An internal thread sampling tool includes a sampling ruler body 1 and an AB-type cured sticky grease 2 bonded to one end of the sampling ruler body 1, and the sampling ruler body 1 is provided with a scale. The AB-type cured viscous fat is prepared by mixing commercially available A-type viscous fat and B-type viscous fat. The sampling ruler body 1 is a stainless steel flat strip with a length of 80mm, the cross section of the flat strip is rectangular, and the scales are respectively arranged with one inch and half an inch length on the flat strip, and the scales are arranged in a staggered manner.

[0035] For the internally threaded hole that needs to be sampled, follow the steps below:

[0036] 1) Prepare the internal thread sampling ruler body and AB type cured adhesive; (see Figure 5 )

[0037] 2) After mixing type AB viscous fat (similar to ...

Abstract

The invention discloses an inner thread sampling tool. The inner thread sampling tool includes a sampling ruler body and AB type curing adhesive grease which is bonded at one end of the sampling ruler body; the sampling ruler body is provided with scale marks; and the thread pitch, thread angle and effective thread length of an inner thread in a threaded hole of a flange are sampled through a resin embossing mode, so that the related dimensions and standards of the thread can be judged. The inner thread sampling tool of the invention is low in manufacturing and material cost. With the inner thread sampling tool of the invention adopted, a phenomenon that a fastener in the inner threaded hole of the flange cannot be installed or is installed in a non-in-place manner can be avoided.

Description

technical field [0001] The invention relates to sampling of flange screw holes in shipbuilding, in particular to an internal thread sampling tool and a sampling method. Background technique [0002] In on-site production, for some special internal threaded holes on the interface of some valves and equipment, the unknown information of the thread angle, pitch, and effective thread length of the internal thread needs to be clarified. For example, the American standard British thread used on imported valve parts needs to be installed with fasteners of correct standards and specifications. [0003] Thread standards are generally divided into two types: metric thread and inch thread, and the external thread angle and pitch of the fasteners that match them need to correspond, otherwise they will not be able to be installed (see figure 1 , figure 2 ). Thread specifications are measured in metric millimeters (mm), and the types are relatively fixed. Generally, they are divided i...
