Gauge and method for measuring distance from side face of forming groove to center of hole

Abstract

The invention discloses a gauge and a method for measuring distance the from the side face of a forming groove to the center of a hole. The gauge comprises a bottom plate, a positioning pin, a screw,an upper slide block, a lower slide block, a plug gauge and a reference plate, the screw pushes the upper slide block to slide on the lower slide block and lifts a measured part to a non-rotatable position, and a through end measurement portion and a stop end measurement portion of the plug gauge are abutted against the reference surface of the reference plate and move downward along the referencesurface of the reference plate to measure the distance the from the side face of the forming groove to the center of the hole. The gauge disclosed by the invention is simple in structure and is easyto manufacture, and the gauge can be used at a working site to improve the accuracy and the working efficiency; the operation method of the gauge is simple, and whether the required measurement size is acceptable can be judged through the plug gauge.

Description

technical field [0001] The invention relates to a mechanical gauge and a method, in particular to a gauge and a method for measuring the distance from the side of a forming groove to the center of a hole. Background technique [0002] see figure 1 , There is a measured part 9 in some special machines, and the measured part 9 includes a body 9-1 and a through hole 9-3 arranged on the upper end of the body 9-1. The main body 9-1 extends to the left and has a protrusion 9-2 upwards. The inner measuring surface B of the protrusion 9-2 forms a first angle α with the vertical line of the through hole 9-3. The measuring surface B and the through hole 9 There is a preset distance L between -3. The lower end of the body 9-1 is a positioning surface A. The preset distance L between the measurement surface B and the through hole 9-3 is a distance that must be controlled within the range of the specified maximum size and minimum size. [0003] Although the preset distance L is a str...

Problems solved by technology

[0003] Although the preset distance L is a straight-line distance, since the distance is the distance between the plane and the center of the hole, and the center of the hole is a spatial point, the value of the distance cannot be directly measured even on a three-coordinate detection instrument, and the detection is cumbersome. , less efficient
