Abstract

The invention provides a caliper tool, which includes two parallel four-bar linkages arranged along the left and right directions and assembled together. point line coincides, the line of two lower hinge points coincides, the symmetrical central plane of the two parallel four-bar linkages is perpendicular to the line of the upper hinge point, and the lower link of each parallel four-bar linkage is respectively provided with a The cylindrical surface of the radial dimension to be measured is pressed against the measuring rod. The two measuring rods are coaxially arranged and are respectively perpendicular to the symmetrical center plane. At least one measuring rod is correspondingly equipped with a dial indicator. The caliper tooling also includes a The synchronous adjustment mechanism is used to drive the two parallel four-bar linkage mechanisms to adjust to and from each other synchronously to ensure that the two measuring rods are always coaxially arranged. The use of two parallel four-bar linkages makes the caliper fixture simple in structure and reliable in action, which can effectively ensure the measurement accuracy of the caliper.

Description

technical field

[0001] The invention relates to a caliper tool. Background technique

[0002] The caliper includes an inner diameter caliper and an outer circle caliper, no matter which kind of caliper includes two long arms hinged together, and the ends of the two long arms away from the hinge shaft are provided with measuring feet or claws. When using, you can use such as figure 1 The cylindrical caliper pair shown is figure 2 The shown outer circular sealing groove is measured, and the two measuring feet of the caliper are pressed against the outer peripheral surface of the cylinder to be measured, so as to realize the measurement of the corresponding radial dimension. For large-sized apertures or outer diameters, general-purpose measuring tools with high precision cannot be directly tested due to the limited range, while general large-sized measuring calipers mostly rely on experience, the measurement error is large, and the accuracy of the measurement size cannot be ...
