Abstract

This invention relates to a measurement technique. The aim of the invention is to expand the information content by measuring not only the outer, but also the inner conical surfaces of the parts. The caliper contains a bar 1, measuring jaws 5 and 6, additional jaws 7 and 8 pivotally mounted on them. The caliper is placed on the outer end surface of the part and the cone diameter is read on a scale of 2 and the cone angle is measured on an angular scale. When replacing additional sponges control the internal conic 5po the surface of the part. 5 il.

The invention relates to a measurement technique, in particular, to devices for measuring linear and angular dimensions, truncated cone parts, for example forgings. The purpose of this article is to expand the information content by measuring no volts w n t l d l g

to external-, but also internal conical surfaces of parts,

FIG. 1 shows a vernier caliper; in fig. 2 - measuring sponge and angle scale; in fig. 3 is a section A-A in FIG. 2j in FIG. 4 - Vernier caliper, operating position for controlling the outer conical surface of the part; in fig. 5 - the same, to control the inner conical surface of the part.

The caliper contains a rod 1 with a scale 2 mounted for movement along the rod 1 frame 3 with a nonius 4, measuring jaws 5 and 6 o On the latter, additional interchangeable jaws 7 and 8 with supporting surfaces 9, designed to interact with the outer conical surface, are hingedly mounted. details 10, or additional interchangeable jaws 11 and 12 with supporting surfaces 13, designed to interact with the inner conical surface of the part 10. On the additional jaws 7, 8, 11 and 12, the vernier 14 is applied. Angular scales 15 41 are applied to measuring lips 5 and 6. The latter have support surfaces for interacting with the face surface of the part. The fixing of additional sponges is carried out at. nut support 17. A screw 18 fixes the position of the frame 3.

The device works as follows.

When controlling the outer conical surfaces by unscrewing the nuts 17, additional sponges 7 and 8 are released

so that the additional jaws 7 and 8 are rotated, then put the caliper on the measured conical surface so that the additional jaws 7 and 8 closely fit the part, and the measuring jaws 5 and 6 abut against the face surface of the part 10. After that fix the position of the additional jaws 7 and 8 with nuts 17. On a scale of 2, the size is read, from which it is subtracted with value sponges with combined measuring jaws 5 and 6, and the size of the truncated cone of the part is obtained. On the angular scale 15 read the angle.

When checking the inner conical surfaces of the parts on the measuring jaws 5 and 6, the additional jaws 11 and 12 are installed and the jaws are carried out. The controls are in the same order as for the outer conical surfaces.
