Problems solved by technology

[0008] However, such a tool changer with a cam reduction gear of the type described above has various disadvantages
On the one hand, the structure of this cam reduction gear is complex and takes up space, because the driving disc, the ball guide in the middle and the driven disc must have a large perimeter
Also, since one rotary motion is transmitted to the radial motion of the balls, which is then transmitted to the other rotary motion, this results in high friction that the spindle drive must overcome, which also leads to increased wear

Abstract

The device has a coupling unit with a coupling element (6) and an oldham coupling having an outer disk (6a) and a middle disk (7), and a gear stage with bevel gears (4) and spur gears (5) for connecting the coupling unit with a tool drum (2). The coupling unit is coupled with another coupling element (106a). Another gear stage has bevel gears (105, 106b) for connecting the latter element with a spindle (101). The drum drives the coupling unit, the elements and the stages to align tool retaining units (2a) when the coupling unit and the elements are coupled with the spindle. An independent claim is also included for a machine tool comprising a tool exchanging device.

Description

technical field [0001] The invention relates to a tool changing device for changing a tool on a spindle of a machine tool, which includes a tool drum, an axle carrier and a transmission device. Wherein the drum tool magazine has a plurality of tool seats arranged along its circumference for holding tools. The drum tool changer is rotatably supported on a spindle frame to align the tool holders with the spindle. Through transmission, the machine spindle drives the drum tool changer to align the tool holders. [0002] Moreover, the present invention also relates to a machine tool, which includes a spindle headstock, a spindle arranged in the spindle headstock, and the above-mentioned tool changing device for replacing a tool on the spindle headstock. Wherein, the drum tool magazine of the tool changing device can be driven by the machine tool spindle through the transmission device to align the tool seat of the drum tool magazine. Background technique [0003] Such tool cha...
