DE1731830U - MILLING MACHINE FOR MACHINING GROOVES, IN PARTICULAR FOR CREATING TOOTH GAPS ON RING-SHAPED WORKPIECES. - Google Patents

Description

! Milling machine for working in from below, especially for creating tooth gaps on ring-shaped workpieces.

The! Rise in prices is based on the task of a! Pre-machine ■ to create for the incorporation of hats, in particular for creating tooth gaps on ring-shaped iron pieces « The machine should preferably be designed for processing according to the Sehla.gfrasverfab.ren *

The! Firing consists of a rotatable clamping is provided for the workpiece and a guide track parallel to the clamping surface for a slide that supports the work spindle of the pre-tool directly carries, or a tool support that can be moved thereon, in which the Work spindle is mounted, with one end of the guide track movable on a stand and in the desired position Distances from the clamping surface can be determined.

In the case of a very large projection of the guideway, it is advisable to the free end of the guideway on a support column supported, with an ar. known clamping device is provided by means of which the end of the! guideway on the column can be determined "

The stand carrying the guide track can either be in the center of the clamping; but he can also be arranged outside the clamping. In the latter part it is useful to move the stand around its longitudinal axis rotatable so that the guideway for insertion the workpiece to be machined can be swiveled out of the clamping area «,

The carriage, which directly carries the tool spindle or which carries the support in which the Tool spindle is stored., Is expedient to a

'■ * for clamping vertical Aci.se designed to be rotatable to

■ ^: for example, hung in a simple manner on the inner one

The '"and outer" surface intermesh . can, -which then

two positions of the slide offset from one another by Ί8Ο ⁰ would have to be set up so that they could be established. It goes without saying that intermediate positions of the slide can also be provided, which would also have to be set up so as to be lockable in order to incorporate, for example, non-radial grooves into the surrounding area.

There are two exemplary embodiments to explain the increase in price in the Pig. 1 and 2 shown schematically

In the embodiment according to Pig. i is 1 a clamping device rotatable about its central axis 2-2, which here - for clamping an entrainment 3 ~ ^ on a much larger diameter than that of the clamping - with

_t . <support arms 4- is provided, with the processing

also provide a support frame 5 is used.

Me clamping 1 can be turned by hand or by machine. It is expediently combined with a known not shown provided healing device.

The stand of the machine is denoted by 6 and is here outside the clamping. On this stand is the beam 7 guided in a plan guide 8 «He can with means known per se, e.g., spindle drive or the like, in its position parallel to the mounting surface WilgSschoben. At the bottom of the beam the guide track 9 is provided, on which a slide 10 can be moved along the guide rail. The sled 10 carries a height-adjustable support 11,

in which the work spindle 12 is mounted, which the Carrying tool 15,

The means for .Antrieb the work spindle 12 and the means for the process of ^s upportes on the carriage 10 are generally known. The slide is horizontally divided into a part 13, which slides along the guide track, and the lower part 14, which is attached to the part 13 so that it can rotate about the axis 16-16, so that the milling tool 15 can pivot, in particular by 180 ° from the position shown for working in external teeth on the singing workpiece 3 is a position for working out internal teeth.

In the embodiment according to Eg * 2, it is annular Clamping device 17 provided in the same way like the stretching according to lig. 1 also with partial facilities The bar 7 is in this embodiment at its free end with an Elemmvcrrichtung 18 equipped, with which it can be fixed on the support column 19 is. The column 19 is in the center of the clamping device 17 "

The stand 6 is outside the clamping. He is executed here as a column with a round cross-section and additionally rotatable on its base 20 about its longitudinal axis, so that the beam 7 na ^ rr. Loosen the clamp 15 and Can be swiveled up from the area above the clamping «
