The reference block of Gage Reference Block is a common action structure. It is not difficult to see from the literal understanding that it is a mechanism that can slide and shift. At present, most common sliding mechanisms are linear motion. If the reference block is used, it can provide enough space for product installation. Now some products under test have complex shapes, and some areas will interfere with the gage during installation. The gage sliding mechanism can better solve this problem. Remove the reference block of the inspection tool before installation, and the product can be reset in translation after installation in place. In addition to these, a movable, precise measurement reference can also be provided. Since the gauge reference block is a straight track, a stable measurement reference point can be provided on the track, thereby realizing the measurement of a single or multiple measurement points on one track.

The gauge reference block has a through-hole sliding mechanism, usually a slider body with a push rod. There is a square hole on the slider body, the square hole is split or closed, and the square hole is a matching push rod. The fit 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 with positioning bolts to achieve precise and repeatable movement. The internal push rod can be arbitrarily set a fixed reference or a measurement reference, so that the sliding mechanism can fix the product or provide a measurement reference. Now this kind of gage reference block usually consists of a linear guide rail 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 display meters, etc., to achieve repeatable measurements. One guide rail can be set with one or more sliders, which is flexible and changeable. The advantage over through-hole slide mechanisms is that repeatable measurements can be accurately achieved over long distances.
