Electric milling machine

The invention relates to a slectrofrase designed as a hand-held device - the eimei im. Gerategahai-.se uBtergssraekten, serving as a drive electric motor and a .presverkzeag sitting on the motor shaft.

The object of the present invention is of course to create a device of the type in question which is used to remove the old putty from the old putty and leftover egg residues on so-called window triangles from old singular or broken windows. To do this, nat laan bis π e r so-called SXtrtf rassn irer - which lait a beck! Equipped sxsi. at

However, these known arrangements result in the disadvantage. that the Lffascnine while working also still
must be turned that the machine has a relatively small contact surface on the Kittfals and that the Maschire
cannot edit a relatively large corner of the window. The aim of the present invention is
in creating a remedy here.

For the above purpose, according to the invention Dei the new electric milling machine is provided that the tool jine running at right angles to the tool axis, at the exact same point
Is assigned to a guide attached to the device, which is provided at at least three points distributed around the tool.

are removed from the plane and the length of the tool axis to change the distance to the tool can be steepened and can be determined in the respective position. The guide expediently consists of a guide plate, the outer surface of which, serving as a guide surface, is contained in a plane running at right angles to the tool axis and which has a recess in its central area, for example round facades through which nindurch the wells with the tool Bach aaBen occurs.

The working depth of the implement is determined. The leadership role
for example on a threaded bolt, for example by means of ball bearings, which can be screwed from the outside into the end of the end of the tool in a coaxial arrangement therewith.

With the help of the new arrangement, the old putty with the
Glass remnants and ITester triangles are simply milled away so that the new pane can then be inserted and freshly cemented. Working with this device is simple and time-saving, the window can be completely removed in practice
will. The new device is also characterized by the fact that the itferKzeug is perfectly guided when working.

Accurate Λ housed, not shown electric motor and a seated on the motor shaft 3 milling 4 Has guide surfaces. This guide plate has an outer surface which is contained in a plane running at right angles to the tool axis and whose distance from the tool can be changed by the plate being arranged to be adjustable back and forth along the tool axis and lockable in the respective position. For this purpose, the guide plate has a guide pin 6 on the side facing the drive motor, the longitudinal center axis of which runs approximately at right angles to the plane of the plate and which engages in a guide bush 7 firmly connected to the housing of the motor, in the longitudinal direction of which the guide pin can be adjusted according to arrow b the respective position is determined, for what purpose an axially unadjustable, but rotatable threaded spindle engages in a threaded hole of the guide bolt, which engages through a guide bushing riilf ^{a of} a rotary handle ^ can be operated. The guide plate has a recess 1o rjcuen cross-section, through which the shaft 3 with the tool 4 nacn. outside critt. the

Outer surface of the opening plate serving as a guide surface is covered by a covering 11 made of plastic material, the guide plate nat Sechtecsforia.

There is one with this on the face of the milling tool coaxial and as twistable "i2 attached during the pras process on Window legs and the working depth of the Serüzeugs certainly. This Fünrucgsrolle sits on a threaded bolt 13, on which it is rotatably mounted by means of ball bearings and from the outside into the face of the tool 4 can be screwed in coaxial arrangement with this. The guide roller is arranged interchangeably, the arrangement it is made in such a way that the tool has a larger or smaller leadership role depending on the required working depth can be attached.

On the edge of the guide plate facing the operator a protective plate 14 is attached, which can be adjusted with the help of the knurled screw / and that too is removable and has the task of protecting the operator from chips that come from the tool.

The shaft of the questioning tool can be detached with the motor shaft in a coaxial arrangement, e.g. connected by a screw connection. 16 is the handle for operating the device, the vco. the electrical supply lines 17 is through.
