Description

Handling device with electric ring magnet oscillating drive

- The invention relates to a handling device with an electric ring magnet oscillating drive according to the preamble of claim 1.

Using the new type of electro-ring magnet oscillation drive in the handling device according to the invention, a work spindle equipped with a suitable tool is set into linear oscillations without contact. This is a sensible structural combination of a few electrical and mechanical components with a high level of efficiency. It is possible to electronically and continuously regulate the size of the linear oscillation movement of the aforementioned work spindle. Such a handling device can carry out a wide range of work processes with tools depending on its structural design.

There are a number of handling devices that work by means of linearly moving work spindles that can be used to carry out striking, cutting or grinding work on workpieces in time. Devices of this type usually have mechanical, electric motor, pneumatic or combined electric motor/pneumatic drives. There are also versions for use in areas without a power supply that are equipped with combustion engines. In some designs, the effective power of the handling device can be adapted to requirements using electric, pneumatic or mechanical controls and transferred to the workpiece to be processed. When it comes to the external design of such handling devices, the majority of manufacturers have favored a housing with a practical handle.

With the known commercially available handling devices with linearly moving work spindles, it can be assumed that the

The characteristic features of such designs lie in the application of known technologies. This applies to the electrical and mechanical components equally. Preferably, the conversion of rotating movements into linear ones is carried out by means of appropriate gear parts. However, the disadvantage of this solution is that

a) power control is also carried out mechanically via these transmission parts,

b) depending on the quantity of transmission parts, the quota of possible sources of error is also

c) all mechanically moving parts cause increased energy consumption due to friction losses,

d) a considerable amount of noise is generated even when idling, and

e) in particular the rotating parts require special care and maintenance.

The invention is therefore based on the object of producing a handling device that consists of a few individual parts in order to reduce possible sources of error, without auxiliary motor structures in size, generates electronically controllable linear vibrations for the contact-free movement of a work spindle, and thus avoids friction losses, with only moderate noise development.

A further requirement is that the construction is easy to clean or even maintenance-free.

This object is achieved in a generic device by the characterizing features of claim 1. The inventive solution is also advantageously supplemented by the characterizing features of claim 2.

The advantages that can be achieved with the invention are in particular that only a few individual parts are used,

and rotating parts such as rotary spindles or variable speed gears are completely absent. As a result, the care and maintenance of the handling device according to the invention is reduced to a minimum. It can also be assumed that the operation of the aforementioned handling device only generates moderate noise.

The contact-free, linearly oscillating work spindle can neither heat up nor generate friction losses, and therefore does not cause increased energy consumption. Io

Io Electro-ring magnet in multi-part design, Pos. 11 internally modified housing with hollow handle, Pos. 12 polygonal magnetic rail&eegr;, Pos. 13 polygonal magnetizable counter mass, whereby Pos.l-lo form the embodiment according to 5 ¹ Ig.1-3. Accordingly, the housing with hollow handle 1 can accommodate either an electro-ring magnet in a completely closed design 4, or an electro-ring magnet in multi-part design Io. The exact installation depth of the electro-ring magnets 4 or Io is limited by a collar located in the housing 1. For the axial displacement of the non-magnetizable work spindle 5 including magnetizable counter mass 6, there is a matching, sleeve-shaped guide piece on the inner rear wall of the housing 1. On the opposite side, the housing 1 is open.

The working spindle 5 including the counterweight 6 is inserted into the guide piece of the housing 1 ready for assembly, with welded-on compression spring guide plate 7 and helical compression spring 8.

The housing 1 is closed by means of the hood 3" in which another compression spring guide plate 7 is welded to the inner head wall in order to support the compression spring 8. The head wall of the hood 3 is provided with a hole in the middle for the passage of the work spindle 5. The end piece of the work spindle 5 protruding above the hood 3 can be completed with a tool 9. The hollow handle of the housing 1 accommodates the electronic control 2. For better handling, the hollow handle can also be covered with grooved shells on the outside. If items 11-13 are used alternately, the design example according to Figure 4 can be created.
