Problems solved by technology

[0002] The size of the rectangular slot is the key dimension that affects the performance of the caliper, but it is difficult to measure the size inside the rectangular slot
According to the original technology, by sampling, the caliper cylinder bore is cut into slices 3 (as shown in Figure 1) and projected under the projector to detect all dimensions. This detection method that can only destroy products is not only inefficient, but also takes a long time. , and cannot guarantee the quality well

Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing:

[0014] This non-destructive rectangular groove size detection method of the present invention comprises the following steps:

[0015] 1) Make a casting mold 2 (as shown in Figure 2-4) according to the shape of a section of the inner cavity wall on the caliper 1, and the selected section of the inner cavity wall includes a rectangular groove 1-1; the outer surface shape of the casting mold 2 It is concave-convex fit with the shape of the inner cavity wall (mainly used to block the fusible metal and prevent outflow), the pouring mold 2 includes the pouring port 2-1 and the pouring cavity 2-2 which are connected to each other, and the pouring cavity 2- 2 and the pouring port 2-1 are cavities with side openings, and the openings of the cavities are located on the outer surface of the casting mold 2 matched with the inner cavity wall;

[0016] 2) Put the pouring mold 2 against ...

Abstract

The invention relates to a size detecting method of non-destructive rectangular groove which includes following steps: producing a pouring model based on shape of wall of inner cavity and outer surface of pouring model, the pouring model includes pouring mouth and pouring cavity which are connected, the pouring cavity is cavity whose side face is open, opening of the cavity is on outer surface of pouring model matched with wall of inner cavity; the pouring model abuts on wall of inner cavity, the fusible metal is poured into pouring cavity from pouring mouth, when it is cooled, metal block whose shape is the same as rectangular groove is formed, the metal block is projected under projecting apparatus for detecting size. The benefit effects of the invention are: the detecting method of the invention not only destroy product, but also increase efficiency, decrease period of detecting, increase frequency, guarantee quality of product.

Description

technical field [0001] The invention relates to a detection method, in particular to a non-destructive rectangular groove size detection method. Background technique [0002] The size of the rectangular slot is a key dimension that affects the performance of the caliper, but it is difficult to measure the size inside the rectangular slot. According to the original technology, by sampling, the caliper cylinder bore is cut into slices 3 (as shown in Figure 1) and projected under the projector to detect all dimensions. This detection method that can only destroy products is not only inefficient, but also takes a long time. , and cannot guarantee the quality very well. The original detection route: sampling - wire cutting - cleaning - projection - detection. Contents of the invention [0003] The present invention aims to solve the above-mentioned shortcomings of the prior art, and provides a non-destructive detection method for the size of a rectangular groove. [0004] Th...
