DE2346619A1 - Test gauge for inner and outer dimensions - can also measure a difference between an inner and an outer dimension - Google Patents

Abstract

The gauge has a sliding bar movable without rotation in a first guide, and a test head movable without rotation in a second guide and connected to a pressure or tension spring with an indicating device. A test arm is provided on the sliding bar and on the test head, each with a contact tip for inner and outer dimensional measurement, rotatable relatively to each other. The two guides are at the ends of a bracket, and the sliding bar and the test head can be rotated over a certain angle about their common axis. The test arms are mounted on the slide bar and test head ends facing each other, and the slide bar and the test head can be set in twisted positions.

Spring standing Heßschlitten against each other displaceable a tubular beam are arranged. There are those Sast links for inside and outside measurements by 180 ° twisted against each other and the Sastglieder for the inside measurement against the load links for the outside measurement by one arranged to be adjustable for a certain value. However, this known arrangement is only suitable for certain applications, since the Distance of the feeler elements for the extension of the tubular Carrier is relatively small can only be made from the face hsr. The arrangement and design of the Sastglieder for the internal measurement in the known device has the effect that an inside measurement in a bore is only possible if the drill rod is from dor ' Hole has been removed. In these cases in particular, however, it is desirable to carry out the internal measurement even when the drill hole is retracted. to be able to make a pole

On the other hand, there is known an internal measuring device which is used for measuring of bores is also suitable when the drill rod is still retracted within the bore. This well-known However, the device has another disadvantage in that it is before carrying out internal measurements with special adjustment means must be set. This setting must be done with great precision, which is the application of this known Device extremely difficult during operation

The object of the present invention is to design a measuring device of the aforementioned type in such a way that it can be used for external measurements can be carried out at any point on the workpiece and not just near the end face. One

Another object is to set up such a device for performing internal measurements so that the Internal measurement can also be carried out with the boring bar inserted, whereby the easy adjustment between Interior and exterior mecsung should be preserved. "

In accordance with the invention this object is achieved in that the «Guess and the second guiding link at the ends of one Lleßrachen forming brackets are arranged, with the caliper and the measuring head can be rotated within the Pührungsglieder by a certain angle about its connecting axis are.

In the Ueßbügel according to the invention, the feeler arms are on the facing ends of the caliper and the measuring head, and the caliper and / Tleßkopf are in uia / "the their Yerbindungsachse twisted locking positions adjustable · The Ließ slide and the measuring head are exactly aligned arranged and guided in a manner known per se with a prismatic profile on prismatic guideways, and the angle between the locking positions is determined by the prism angle

Invention sgeraäß are the feeler threads on the feeler members around one Angle between 30 and 180, preferably 180, rotated against each other. The prism angle is then preferably 90, so that the connecting line between the feeler elements of the respective Probe arms in a first locking position of the caliper and ileßkopf in the plane of the measuring bracket and in a second Locking position runs perpendicular to it.

Advantageously, in the measuring bracket according to the invention, the feeler elements for the internal measurement are L-shaped, the the shorter leg is provided with a touch surface and the longer leg is designed as a contact surface
