DD145453A3 - DEVICE FOR WORKING WORKPIECE SURFACES, ESPECIALLY FOR DEBATING - Google Patents

Abstract

A device for mechanically machining workpiece surfaces, particularly for deburring, which can be used within an automated machining process, preferably for deburring recessed workpiece contours, but can also be used for other technological processes, such as polishing, descaling, derusting, matting, and roughening. As can be seen in Fig. 1, attachment tools 14 are arranged on the output spindles 11 of a planetary or epicyclic gear. A gear unit is mounted with its gear housing 3 on a spindle 1 and is operatively connected to a holding or controllable drive element 9. Rotation of the spindle 1 causes the attachment tools 14 to rotate along one or more flight circles and, for example, remove the existing burr edges. — Fig. 1 -

Öas Anwendungsgebiet- the invention extends to machines in metalworking *.

Cfaarakteristitc the known technical solution Pur mechanical machining of workpiece surfaces, especially for deburring, are a variety of technological ..

The method of irradiation is known in Tronunel-Oaeer. The method of application is by means of a blasting medium. The further method is the Stoic and Crescent experiment, which is mainly used for chamfering and burring vexzalinter parts is applied. Beiia Nadelf rasen comes a special tool,

15. Consisting of a thinly packed, thin high-strength steel wire forming a multitude of cutting edges. «

• An essential maelstrom of these devices is that a deburring of recessed workpiece contours, which are

2-0 are within plan and / or jiing areas, or

limiting such form, in particular on special machines and production lines ,, or only with great ^A ufwand possible.! is « ^!

Object of the invention

^Ä ls aim of the invention is to be achieved ,, that in a simple wayin an automated processing sequence ^ in a series or mass processing of workpieces preferably a deburring of recessed workpiece contours, which are located within plan and / or annular surfaces, or the limitation thereof, can be done by machine with high deburring effect.

DESCRIPTION OF THE NATURE OF THE INVENTION The hangers described in the characteristics of the known technical solutions can be traced back to the following causes

- The system structure for drum or ü _ur chlaufanlagen requires a relatively large amount of space and can be difficult in the automatic ^. Classify the work process of machine tools.

""& ex use of conventional deburring brushes when deburring zurückgesetztter surfaces requires in addition to .Drehbewegung usually still a feed and / or feed movement with a relatively high control effort. To eliminate these causes, the invention has the object, a .Einrichtung for processing Ferkstückoberflächen create za, which allows the deburring zurücksetzter Vferkstuckkontüren, allows an adaptation to the respective workpiece contour and can be used with a low Steaerungsaufwand in special machines and production lines · is.

Srfindungsgeaäß this is achieved in that attachment tools on output spindles of a planetary or

Spherical gear wheels are arranged and the gear box is mounted on a spindle with '' *. an ice halt or steudrbar'en drive element -in -Wirk connection stands.

c -Ia dependence on the. It is intended that all attachment tools be adjustable _? can be arranged on one or more sides of the circle at equal angles of inclination to one another in the same direction or in opposite directions. ·

It is also intended to be used as attachment tools:. The use of differently designed attachment tools makes it possible to use the device according to the invention for aadex-3 technological methods

As can be seen in Fig. 1, all one spindle is fastened to a machining mechanism ( not shown), one half- body, two gearbox housing 3, and in this

a shaft 4 with fixed st eiling central wheel 5 in the bearings 6; 7 rotatably mounted ₄

The shaft 4 is connected via a coupling part 8 with a holding or Antriehselement 9. The holding or drive element 9, which 'stent' in operative connection with the shaft 4, is guided through the bore of the spindle 1 and fixed rigidly in the illustrated embodiment outside of this,

The fixed central wheel 5 is connected to a circulating

To bzjy »Planetary wheel 1c in the singing riff; which is located on the output spindle TI. The output spindle 11 is mounted in the bearings 12, 13 in the transmission housing 3. On the output shaft 11, a replaceable attachment tool 14, for example a Dekarbonisierbürste, arranged,

In Figure 2 a gehäuseför-naiges workpiece 15 is shown, in which the two planar surfaces 16, 17 and the webs 18 with their associated G-ratKanten 19; 2o and 21 are lower than the outer contour of the workpiece 15 ·

The mode of action is the following:

If the spindle 1 is set in rotary motion, the gear housing 3 fixed to the spindle 1 at the same time rotates and causes the planetary gear 1o to roll on the stationary central wheel 5 and the power take-off spindle 11 Eric-.

14 rotates on a circular path. The superposition of the rotational movement of the attachment tool 14 with the rotational movement of the gear housing 3 leads to a constant change in the Wirkriclitung the individual wires of, for example, coming Dekarb.onisierbürsten. The deburring effect is intensified by virtue of the direction of action of the tool being as perpendicular as possible to the edge of the gate and to the direction of the G-rate of the G-rate.

The direction of the transmission housing 3 and of the attachment tool 14 zöimeii accordingly be chosen «
