These processing units have a number of disadvantages explained below:
Replacement of abrasive strips requires manual intervention. Most often, tools are required to separate the individual parts of the processing unit. Thus, time and both hands are required to change the abrasive strips. Generally, the abrasive strips will be firmly mounted in a plate-shaped holder and in these cases it is the plate-shaped holder that requires the use of both hands for replacement.
Furthermore, the abrasive strips cannot be replaced by a robot. For example, in an automated manufacturing or machining line in a factory. Here again, the abrasive strips al

A further disadvantage of the known machining units is that it is too complicated to change the grinding strips when working on a wind turbine or a wind turbine blade at high altitude. Here, an easy and fast one-handed operation is a necessary prerequisite that is not met by the known processing units.
The object of the invention
It is the object of the present invention to provide a machining unit which addresses these drawbacks.
Further, the object of the invention is to provide a machining unit in which the abrasive strips and / or the other plate part can be easily and quickly replaced.
Further, the object of the invention is to provide a single-use operable processing unit.
Further, the object of the invention is to provide a machining unit that can be used in the wind turbine industry.
Further, the object of the invention is to provide a machining unit that can be used in the composite, metal, and wood industries.
It is a further object of the invention to provide a machining unit which, in addition to hand machines, can also be used by robots and other automated machines.
Description of the Invention
This is achieved in accordance with the present invention with a processing unit of the type initially specified, which is characterized in that the processing unit comprises:
- a locking mechanism connecting the first and second plate parts, wherein the locking mechanism is rotatably mounted on the first plate part with rotation about the axis of rotation,
Which locking mechanism comprises a central part formed of a circular plate and an associated annular wall, as well as at least two locking pins, which annular wall is connected to the at least two locking pins that the first plate part and the second plate part have openings which are aligned by assembly and arranged to receive a distal end portion of the locking pins, that the distal end portion of the locking pins, when rotating the annular wall, is displaced radially between a first locked position where the distal end portion engages the aligned openings and a second unlocked position outside the aligned openings such that the first and second plate members are interlocked or non-locked, respectively, that the annular wall extends through an annular opening in the second plate portion and the central portion is provided. with an operating handle for rotating the locking mechanism.
The abrasive strips are the tools and / or host tool elements that the tool holder is intended to hold.
The abrasive strips may be suitable for use in any abrasive or polishing tool.
The abrasive strips may be attached to the first sheet portion.
Alternatively, the abrasive strips may be releasably connected to the first sheet member.

The ribs support the abrasive strips and hold them in place. The ribs may be located in the radial direction. The ribs may advantageously be higher in the proximal end portion than in the distal end portion near the outer edge of the first plate portion. Thus, it is obtained that the height of the abrasive strips in the direction of the axis of rotation is lower in an outer region than in a central region of the machining unit. Outer area and central area are here seen in the radial direction. That is, the outer region is near the radial outer edge, while the central region is near the center in the radial direction.
According to a further embodiment, the processing unit according to the invention is characterized in that a first pin on the inside of the annular wall engages an L-shaped groove in an annular support wall on the first plate part.
The first tab and the L-shaped groove match the first plate portion and the locking mechanism.

According to a further embodiment, the processing unit according to the invention is characterized in that the first plate part and the second plate part comprise a second guide for controlling the first and the second plate part during mutual rotation during assembly of the processing unit.
The first and second plate parts are arranged so that they engage only when the openings in both plate parts are aligned.
Thus, the second plate portion can be rotated on the first plate portion while exerting a slight pressure along the axis of rotation when assembling the processing unit.
When the openings of the first and second plate parts are aligned, the plates engage and cannot be rotated further relative to one another. Subsequently, the locking mechanism can be locked by rotating the handle. This increases fast and easy operation.
A further aspect of the invention is the use of a processing unit according to any one of the preceding claims in a robot.
The processing unit is particularly suitable for use in robots.
The locking mechanism can be operated easily by a robot. There are well-defined outer positions for the grip in the unlocked and locked position.
DK 2018 70529 A1
The locking mechanism may be designed as a single item. Thus, there are no individual parts that can become detached during use. Since a robot would not be able to detect loose parts, this is a significant advantage.
Furthermore, the second plate portion and the first plate portion are designed to engage only when the openings of the first and second plate portions are aligned. Thus, a replacement of the second plate part or the grinding strips can be made with a simple and fault-tolerant programming of the robot.
A further aspect of the invention is the use of a machining unit according to any one of the preceding claims in a hand tool for machining a wind turbine, preferably a wind turbine blade.
The machining unit is particularly suitable for use in demanding work situations such as machining a wind turbine blade. The other plate part and / or the grinding strips can be changed with a single one-handed operation without tools. Thus, time is saved and security is increased.
The handle is easily accessible in the central part of the machining unit.
The first and second plate parts are arranged so that they engage only when the openings in both plate parts are aligned. Thus, the second plate portion can be rotated on the first plate portion while exerting a slight pressure along the axis of rotation when assembling the processing unit. When the openings of the first and second plate parts are aligned, the plates engage and cannot be rotated further relative to each other. Subsequently, the locking mechanism can be locked by rotating the handle. This increases fast and easy operation.
