Checker sliding mechanism is a common action structure. It is not difficult to see from the literal understanding that it is a sliding and shifting mechanism. organization. Most of the current common sliding mechanisms move on a straight line.

The main function of the gage sliding mechanism:

1. Provide enough product installation space

Some tested products have complex shapes, and some areas will interfere with the inspection fixture during installation. The gage sliding mechanism can better solve this problem. The mechanism is removed before installation, and the product can be reset in translation after it is in place.

2. Provide a movable and accurate measurement benchmark

Because the gage sliding mechanism is a straight line track, it can provide a stable measurement reference point on this track, so as to achieve a track for single or multiple Measurement of measurement points.

From a structural point of view, sliding mechanisms can be divided into two categories:

1. Through-hole sliding mechanism

This mechanism is usually a slider body with a push rod. There is a square hole on the slider body, the square hole is a split structure or a closed structure, and the square hole is a matched push rod. The matching clearance on one side is generally 0.01MM. The push rod can move linearly in the square hole, and the moving position can be fixed by positioning bolts to achieve precise and repeatable movement.

The push rod can be arbitrarily set as a fixed reference or a measurement reference, so that the sliding mechanism can fix the product or provide a measurement reference.

2. Rail type sliding mechanism:

This mechanism usually consists of a linear guideway and a matching slider. The guide rail is fixed on the body of the inspection fixture, and the slider can move linearly on the guide rail. Sliders can be equipped with measuring benchmarks or other measuring tools such as plug gauges, digital displays, etc. , so as to achieve repeated measurements. One rail can be set with one or more sliders, which is flexible. Compared with the through-hole sliding mechanism, the advantage is that repeatable measurements can be accurately realized over a long distance.
