Problems solved by technology

[0009] The purpose of the present invention is to provide a check pin go-no-go gauge with an open structure and a stop-end that detects whether the size of a certain position on the pin is qualified, so as to solve the problem that the conventional pin-check go-stop gauge is difficult to achieve the detection

Embodiment Construction

[0026] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Such as image 3 As shown, the pin check through stop gauge 1 includes a handle 3 and a pin check end 11 and a check pin through end 12 respectively arranged at both ends of the handle 3. The pin check end 11 and the check pin through end 12 are open structures, The open structure is a sheet-like structure with holes in the middle.

[0028] In order to facilitate the use and manufacture, the sheet structure with the middle opening is a circular ring structure. Of course, it can also be made into other shapes such as hexagons, quadrilaterals, etc., with only the middle opening.

[0029] The thickness of the sheet-like structure with the middle opening is 3-10 mm. Preferably, the thickness of the sheet-like structure with the middle opening is 5 mm.

[0030] Such as Image 6 As shown, according to the requirements of the drawing, the size of...

Abstract

The invention discloses a pin inspection go / no go gauge. The pin inspection go / no go gauge comprises a handle, a pin inspection no-go end and a pin inspection go end, wherein the pin inspection no-go end and the pin inspection go end are arranged at the two ends of the handle respectively and are of open structures. Each open structure is a sheet structure with a hole formed in the middle. In conclusion, the pin inspection go / no go gauge has the go end and the no-go end of the open structures, and the size of a certain position of a pin can be accurately detected. Moreover, the materials of the pin inspection go / no go gauge are similar to those of a conventional pin inspection go / no go gauge, the machining cost is not increased, and thus cost is not increased.

Description

Technical field [0001] The invention relates to a pass-and-stop gauge for quickly detecting whether the hole size is qualified. Background technique [0002] Inspection fixture is also called inspection fixture. It is a special inspection equipment designed and manufactured to inspect the product's overall dimensions, surface shape and other position states. [0003] At the parts production site, the online inspection of the shape, contour, size and hole size of the part is realized through the inspection tool. For this reason, the part needs to be accurately installed on the inspection tool, and then the part type is measured by visual inspection, height difference ruler, caliper and other tools. Inspect the surface and periphery to ensure rapid judgment of the quality status of parts during production. [0004] For plastic parts, due to the use of injection molding, the holes and pins of the product will have a draft angle (the pin is taken as an example below), that is, the two ...
