Abstract

A pipe milling machine for separating and/or cutting a pipe to length is disclosed. In an embodiment the pipe milling machine includes a milling wheel configured to separate the pipe and a motor configured to generate a feed of the pipe milling machine and to drive the milling wheel, wherein driving the milling wheel is independent of separating the pipe.

First claim

What is claimed is:

1. A pipe milling machine for separating a pipe to a length, the pipe milling machine comprising:
a device for generating a feed of the pipe milling machine;
a milling wheel for processing the pipe;
a device for driving the milling wheel, wherein the device for generating the feed and the device for driving the milling wheel are independently operable from one another; and
a lever configured to control the pipe milling machine,
wherein the lever is rotatively turnable, so that positions of plunger pins and balls for controlling of a worm gear are changeable, the worm gear being configured to turn on or off the device for generating the feed,
wherein the worm gear is arranged on a milling shaft of the milling wheel,
wherein a switcher shaft, axially adjustable by the lever via a motion link, is provided and acts on the balls, the balls being mounted radially adjustable in the milling shaft to couple or decouple the milling shaft and the worm gear to turn on or off the device for generating the feed.

2. The pipe milling machine according to claim 1 , wherein, in a first operating condition of the pipe milling machine, there is no feed generated but a drive of the milling wheel is present.

3. The pipe milling machine according to claim 2 , wherein, in a second operating condition of the pipe milling machine, there is a feed generated and a drive of the milling wheel is present.

4. The pipe milling machine according to claim 3 , wherein, when the lever is in a first position, the first operating condition is present, and/or wherein, when the lever is in second position, the second operating condition is present.

5. The pipe milling machine according to claim 1 , wherein the device for generating the feed and the device for driving the milling wheel are driveable by a single electric motor.

6. A pipe milling machine for separating a pipe to a length, the pipe milling machine comprising:
a milling wheel configured to separate the pipe;
a lever configured to control the pipe milling machine; and
a motor configured to:
generate a feed of the pipe milling machine; and
drive the milling wheel,

wherein driving the milling wheel is independent of generating the feed of the pipe milling machine, and
wherein the lever is rotatively turnable, so that positions of plunger pins and balls for controlling of a worm gear are changeable, the worm gear being configured to turn on or off the generation of the feed,
wherein the worm gear is arranged on a milling shaft of the milling wheel,
wherein a switcher shaft, axially adjustable by the lever via a motion link, is provided and acts on the balls, the balls being mounted radially adjustable in the milling shaft to couple or decouple the milling shaft and the worm gear to turn on or off the device for generating the feed.

7. The pipe milling machine according to claim 6 , wherein, when the lever is in a first position, the motor does not provide a feed motion while driving the milling wheel, and wherein, when the lever is in a second position, the motor provides the feed motion while driving the milling wheel.

8. The pipe milling machine according to claim 1 , wherein the plunger pins are disposed within the motion link that is connected to the lever.

9. The pipe milling machine according to claim 8 , wherein the motion link is connected to a bearing cover.

10. The pipe milling machine according to claim 6 , wherein the plunger pins are disposed within the motion link that is connected to the lever.

11. The pipe milling machine according to claim 10 , wherein the motion link is connected to a bearing cover.
