Gauge and method for measuring slope intersection point distance dimension on part

Abstract

The invention provides a gauge and method for measuring the slope intersection point distance on a part conveniently. A measuring block is fixed to the front right corner of a bottom plate. A measuring slope is arranged on the rear left corner of the bottom plate, wherein a measuring angle equal to a limiting angle on the part is formed between the measuring slope and an extension face formed by the rear face of the measuring block in a leftward extension mode. A positioning block is integrally fixed to the bottom plate and located on the rear left portion of the measuring block, the front face of the positioning block is located in front of the rear face of the measuring block, and the basic measuring perpendicular distance between the intersection point of the rear face and the right side face of the positioning block and the measuring slope of the measuring block is larger than the perpendicular distance between the intersection point of the right end of the bottom base face of a protruding portion of the part and the top end of the left base face of a body and a limiting slope. A plug gauge comprises a plug gauge body, a through end and a stop end, wherein the through end and the stop end are connected to the two ends of the plug gauge body, the width of the through end is equal to the maximum value obtained by subtracting the perpendicular distance from the basic measuring perpendicular distance, and the width of the stop end is equal to the minimum value obtained by subtracting the perpendicular distance from the basic measuring perpendicular distance. The perpendicular distance is equal to the value obtained by multiplying the quotient of the sum of the width of the body of the part and the slope intersection point distance and the tangent value of the limiting angle on the part by the sine value of the limiting angle.

Description

technical field [0001] The invention relates to mechanical measurement, in particular to a gauge and a method for measuring the distance dimension of inclined plane intersections on parts. Background technique [0002] see figure 1 As shown, in some special machines, there is a part 5 that plays a position-limiting role, which includes a body 5-1 with a width t and a protrusion that protrudes from the left end of the body 5-1 to the left and plays an assembly positioning role during assembly. The raised part 5-2, the bottom surface of the raised part 5-2 is the bottom base surface A, and the part of the left side of the body 5-1 below the bottom base surface A of the raised part 5-2 is the left base surface B , Between the right side and the bottom of the body 5-1, there is a limiting slope G that slopes upward from the left side of the bottom to the right and is much lower than the bottom base surface A of the raised portion 5-2. The limit angle β1 is formed between the e...

Problems solved by technology

However, due to the large size of the three-coordinate machine and the high requirements for the use environment, it cannot be used on the production site

Therefore, using a three-coordinate machine to detect the distance Z of the intersection point of the inclined plane can only be carried out by transferring the part 5 to the location of the three-coordinate machine. The detection is very inconvenient and the efficiency is low

At the same time, the three-coordinate machine is expensive, and the three-coordinate machine is specially prepared to detect the distance Z of the intersection point of the inclined plane, and the cost is also high
