Description; Vernier caliper for grapezoidal thread

The caliper is used to find the values quickly and easily for the three-wire measurement, which are required for the production of such threads. Previously, these values were based on the following formula calculated. In it is

Ρ © = theoretical test dimension

e / ϊ = theoretical plank diameter

h = thread side itjung ^ ^J -

(depending on the slope)

This caliper enables every mathematician to to find the value you want. Only the one from the Heßschieber is used for this purpose Readable ¥ ert reduced ten times and coupled with an addition. Et is for workshop people such as lathe operators, milling cutters and inspectors , developed and intended to be used in the manufacture of machine parts. Lr can be used for both catchy and multi-thread Clewindeii are used. In its present size it is designed for 50 different threads. It is composed of 4 ropes. Its accuracy in terms of the reading './erte results from the system that the measuring process in magnified Circumstances happens.

In principle, it embodies a tenfold enlarged passage gap in the ITormal cut. The measuring lines visible on it are on the position the! lank arranged through it. The route at the clear "■ feite in the prism, at the same height as the measuring lines, corresponds to half the! Division of the thread sizes readable there, which in each case have the same slope. This results in the relatively large one Scope of application. In the lower half on the right is a threaded hole M 6j it is used in conjunction with a normal cord tube M 6 for setting the plate in an inclined plane, corresponding to the angle of incline. This will cause the incline of the measuring wire is taken into account as a correction factor. You lean

depends on the pitch and wins with multiple threads especially in importance. In the guide groove located a: xial to the prism A caliper slides, whereas in the prism groove 1 scale is arranged adjustable.

Rope 2 slide

Sr is in the guide groove ύοώ. Part 1 - plate - arranged to be slidable. A vernier is attached to its flat on the right, by means of which the value y can be read from part 3 - scale - to an accuracy of 1/10.

5 scale rope

Sr is in the prism guide groove of part 1 - plate - verschiebbat arranged. At its bottom is in a feather key Milling a leaf spring - part 4 - concave inserted with pretension, to lock it in the hot position.

l'eil 4 leaf spring:

It is 5 mm concave and is on the scale - part 3 The convex part is supported in the prism groove base of part 1 plate.

Reading process

First, the plate is to be inserted into the threaded hole M 6 by means of a M 6 cord screw brought into the slight incline (equal to the pitch angle) of the corresponding thread. The plate remains on the resulting 3-point support. Am G-renzlehrdorn of ten times the diameter of the later in the thread production The measuring wire to be used is placed with its good side vertically in the flat prism of part 1 - plate - and placed by light pressure on the points of contact of the same. The diameter of the limit gauge is to be chosen so that the points of contact be as close as possible to the measuring line of the thread named there. Then the yardstick - part 3 - is with its hull To bring the desired thread size into exact correspondence with the measuring line by moving it, ifaclidem becomes part of the slide 3 - adjusted from below to the periphery of the limit plug gauge and by means of its vernier the ¥ ert y from the scale - part 3 - up Read 1/10 accuracy. The measuring process is finished.

Claims (1)

Sheet 3 for the application for a sample Langbein Heustadt, the 8632 ITeustadt / Öbg.
OstpreuiBenstrasse \ evaluation; A practical application in three-wire measurement is that of liaßstab - part 3 - read off value y first to decrease 10 ζ and then subtract it from the measuring wire thickness, whereby the Tfert ζ is found. The value for the three-wire measurement is then 2 χ + pitch diameter. The manufacturing tolerance is to be assigned individually. Other The 1-ießdruck, which can be assumed with 1 kg, brings a hot wire flattening. This is 3-6 my, it is to be added to the total value. With turned and milled parts but they can also be omitted, since they are mostly lost in the manufacturing tolerance that is attributable to manufacturing. Claim to protection Caliper for trapezoidal thread, characterized in that measuring lines and Size information in 2 guides, 1 slide with vernier and 1 scale with leaf spring are arranged to be displaceable. Caliper for trapezoidal thread naön ^ claim 1, characterized characterized in that the Mejtfinienstverbindungen on the measuring plate in the part denoted by the prism imterbrp <5 of half the slope of the there named container - enlarged several times - correspond. Furthermore, that you ^ ch the threaded hole M 6 in the measuring plate the entire device can be placed in inclined planes. Γ " -χ · copy P.A.
