DE1477464C - Device for setting spindle-shaped stops on an exchangeable stop drum for machine tools - Google Patents

Description

he touches the micrometer screw tip 14 α; then the stop screw 12α is fixed, for example by means of a screw 16a . Appropriate settings can then assumes the other stops for the cutting depths P ₁ + P ₂ and P ₁ + P ₂ + Ps ^ago ·

Thanks to the invention one achieves a great one

Security and accuracy of setting, what even if one does not necessarily have this accuracy required, makes this device usable with or without a pre-cut template.

In the holder 10 there is finally a freely movable one rod-shaped screwing tool 15 stored, one end of which has a control button 15 a and The invention relates to a device for adjusting the other end of which carries a means 15 b for rotating the spindle-shaped stops of an interchangeable ₄₀ stop screw of the drum, e.g. B; a cash stop gimbal. For machine tools, hexagon socket wrench that fits in .Shechiägspihdeln of their Arischiägspihdeln äfchspärällel to the drum ends of the stop screws. This rod axis at the same distance from the drum axis is arranged coaxially to the tip 14 of the micrometer screw and is provided at its rear end with a nozzle or polygon that corresponds to the adjustment of the individual stops, iri the or 45 depending on the peek depth step values one after the other on which a screwing tool a ¹ or attached subsequent cuts is facilitated in this way,
can be. Assume that it is a workpiece 20 (FIG. 4). In known stop drums (e.g. USA.- from the blank diameter r to the step-by-step patent specification 945 947) the stop spindles are to be turned off with decreasing radii / · ^ r # r ₃ and r ₄ , usually on the lathe itself, namely 50 Then the first cut must have the depth P ₁ == V ₁ - T ₂ , by trying out a sample workpiece, the second the depth p ₂ = r ₂ - r ₃ and the third the posed. This is quite cumbersome and since depth p ₃ = r ₃ -r ₄ have. So there are the fact that the bank cannot "be used" or "beat the drum" is set so that the post-operational costs are expensive. It is faster and cheaper to use the forming device to execute the depth of cut p _v stops to the predetermined dimension - e.g. from the construction drawing 55 p ₂ , p _s by means of a micrometer stop is done by adjusting on the microscrew. A device which sets this one-meter screw to the desired value of the cutting depth position of the stop spindles by means of a micrometer of the cut, based on the pipe diameter 2 r meter screw, with the most convenient, fastest 60 of the workpiece 20, and then the end of the and most precisely Adjustment is made possible, the stop by means of the adjusting rod 15 is up to the end of the invention. brings the micrometer screw tip 14 α agitation. This consists of using a micrometer screw when presetting the stops to determine the measuring length: First, bring the micrometer screw 65 stop 12 a into alignment with the micrometer and the screwing tool together in a screw 14 , sets on the micrometer screw the U-shaped holder are arranged, in whose one value the cutting depth P _{1 of} the first cut and U-leg the nut of the micrometer screw rotates the stop 12 a by means of the rod 15 until
