CN201116863Y - Checking gauge for detecting coupler knuckle rotation point sample plate figure and dimension - Google Patents

Abstract

The utility model relates to a check gage which is used to check the size of the appearance of a sample plate of a rotating point of a coupler knuckle, which is provided with a flat surface structure, and the shape and the size of the cross section are equal to that of the locking surface of the coupler knuckle, the check gage also comprises a positioning hole and a circular arc section. When in use, the positioning hole of the check gage is sleeved on a positioning bar, and the relative position of the sample plate of the rotating point of the coupler knuckle is controlled by four slide blocks, which is adjusted to the inner end face of the slide blocks to be tightly attached with the check gage, and the gap between the relative circular arc section on the sample plate and the circular arc section on the check gage by a 0.1mm clearance gauge, if the check gage can not pass through, and then the sample plate of the rotating point of the coupler knuckle is tested to be acceptable. The check gage has the advantages of simple structure and convenient employment.

Description

A kind of reference gauge that is used to detect hook tongue run-on point model physical dimension

Technical field

The utility model relates to a kind of reference gauge that is used to detect hook tongue run-on point model physical dimension.

Background technology

The hook tongue run-on point model complex structure of fixing, rotatable coupler, need to look for a detection to judge whether it adheres to specification with the high-precision three-dimensional lining instrument, waste time and energy and detect the cost height, if here greatest can detect then good fortune with the dedicated test model, domestic unfortunately hook tongue run-on point model fixing, rotatable coupler does not still have special-purpose reference gauge at present it is detected.

Summary of the invention

The purpose of this utility model is to provide a kind of reference gauge that is used to detect hook tongue run-on point model physical dimension, better to overcome above-mentioned defective.

The technical solution of the utility model is: a kind of reference gauge that is used to detect hook tongue run-on point model physical dimension, and it is characterized in that: it has planar structure, and its cross sectional shape and size are equal to the cross sectional shape and the size at hook tongue seat locking face place; It also contains pilot hole 1 and arc section 2.

This check and correction amount is returned has advantage simple in structure, easy to use.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is synoptic diagram of the utility model physical dimension when being used to detect hook tongue run-on point model.

Among the figure: 1-pilot hole, 2-arc section, corresponding arc section on the 3-hook tongue run-on point model, 4-backstay, the slide block on A, B, C, the D-hook tongue run-on point model.

Embodiment

Referring to accompanying drawing, the pilot hole 1 that to proofread during detection on the gauge is inserted in backstay 4, relative position with A, B, four slide block control of C, D hook tongue run-on point model, it is closely connected to transfer to slide block inner face and reference gauge (indicating with dot-and-dash line among Fig. 2), detect gap between arc section 2 and the arc section 3 with the 0.1mm clearance gauge again, as can not be qualified by then showing hook tongue run-on point model.

Claims (1)

1, a kind of reference gauge that is used to detect hook tongue run-on point model physical dimension, it is characterized in that: it has planar structure, and its cross sectional shape and size are equal to the cross sectional shape and the size at hook tongue seat locking face place; It also contains pilot hole (1) and arc section (2).
