Definitions
- the invention relates to a slip ring transmitter with the features in the preamble of the main claim.
- the invention has for its object to show a better slip ring transmitter.
- the invention solves this problem with the features in the main claim.
- the slip ring transmitter has the advantage that the simpler arrangement of the slip ring and a modular brush block with brushes make maintenance and repair of a complicated disassembly of the machine parts unnecessary, and still ensures reliable and precise assignment of the brushes to the slide tracks during installation. In addition, assembly and disassembly are simplified and damage and incorrect handling avoided. Special adjustment work is not necessary. In the operating position it can Brush module are locked and thereby assumes the correct and precise position precisely and automatically.
- the guide for the brushes consists of opposing one another
- the carrier plate in the area located outside the wall of the second machine part has an externally accessible cavity for receiving one part of an electrical plug connection for connecting a third machine part that can be connected to the second machine part.
- the third machine part which can be, for example, a tool, in particular a robot-guided welding gun, can be supplied with current independently of the rotational position of the second machine part.
- the invention has the advantage that to clean the slip ring and the sliding track, the brush block only needs to be released from its connecting position with the second machine part, whereupon the
- Brush block is raised slightly until the board comes back into engagement with the slots in the guide. Now the brush block can be pushed out freely. Through the now exposed recess, a cleaning device can then be inserted into the interior of the machine part in order to clean the slip ring or the slide tracks.
- the object of the invention can be . Use everywhere in mechanical engineering and device technology, advantageously also in industrial robots, where it is important to establish a power connection via machine parts that are nested and rotatable relative to one another.
- FIG. 1 a slip ring transfer device in plan view with machine parts that are nested in one another with slip rings and brush modules,
- Figure 2 is a side view of the slip ring transmitter in the direction of
- FIG. 3 a broken vertical cross section through the second machine part according to section line III-III in FIG. 1,
- Figure 4 a vertical cross section through the
- Figure 5 and 6 a brush module in side view and folded top view.
- FIG. 1 shows a partially broken top view of a slip ring transmitter which has at least two machine parts (1, 2) rotatably mounted relative to one another, of which a first machine part (1) serves, for example, as a stator and a second machine part (2) as a rotor ,
- the machine parts (1, 2) can be mounted one inside the other or one on top of the other, but alternatively can also be stored independently.
- With (18) the axis of rotation of the rotor (2) is designated.
- the arrangement is also kinematically reversible, according to which the machine part (2) can be relatively stationary and the machine part (1) can be rotatably mounted for this purpose.
- An electrical current can be conducted via the machine parts (1, 2) which can be rotated relative to one another and can also be conducted, for example, to a third machine part (not shown) without the power supply being dependent on the relative rotational position of the machine parts (1, 2).
- the current is transmitted by means of one or more slip rings (3) and one or more electrical contact elements, preferably brushes (16).
- the brushes (16) are preferably grouped together in brush blocks (7) and, together with other parts, form brush modules (19).
- Machine part (1) at least one flat slip ring (3), on the surface of which one or more slide tracks (4) arranged concentrically to the axis (18) and provided with corresponding supply lines are arranged as current conduction.
- a plurality of slip rings (3) can also be arranged at a distance above one another in the machine parts (1, 2) and differently designed slip tracks (4), e.g. for power and signal currents.
- the brush module (s) (19) are detachably arranged on the second machine part (2).
- the brush module (19) is inserted and removed by means of a combined insertion and positioning movement in different directions in the associated machine part (1, 2).
- the brush module (19) has at least one brush block (7) with a plurality of brushes (16) which transmit current with the assigned grinding tracks (4)
- the brush block (7) is on the top or bottom of a board (10) arranged, which in turn is connected to a preferably plate-shaped carrier part (8) and projects transversely therefrom.
- Machine part (2) inserted and then can be positively locked in a transverse movement for positioning in the operating position.
- Figure 4 shows the arrangement in cross section.
- the recess (5) has lateral guides on the laterally delimiting walls (6) in the form of transverse slits (11) opposite one another at the same height, the height of which corresponds approximately to the thickness of the free longitudinal edges (17) of a single circuit board (10) ,
- Figure 2 shows in the left half of the board (10) in the insertion position in the slot (11). The lowered click position is shown in the right half of the picture.
- the carrier plate (8) extends along the axis of rotation (18) and is flattened from the outside
- the individual brushes (16) are fastened to the circuit board (10) and are connected to an electrical plug connection (15), preferably in the form of a pin strip (21), by appropriate cabling, which are located in a cavity (14) of the carrier plate (8) and are accessible from the outside for an electrical socket (22) to be fitted.
- an electrical socket connection preferably in the form of a pin strip (21)
- cabling which are located in a cavity (14) of the carrier plate (8) and are accessible from the outside for an electrical socket (22) to be fitted.
- the assignment of socket and pins can also be reversed.
- the brush module (19) with the circuit board (10) can be moved and inserted through the recess (5) into the interior of the second machine part (2) transversely to the axis of rotation (18) in such a way that the brushes (16) not with the sliding tracks (4) in
- the height of the recess (5) and position of the slots (11) in the axial direction (18) relative to the associated slip ring (3) are selected such that the board (10) with its brushes (16) passes through the slots (11 ) has a sufficiently large distance to the lower recess edge (23) and to the grinding tracks (4).
- the board (10) should and can be lowered into the operating position and locked into place.
- the depth and length of the recesses (13) are adapted to the width of the recess (5) and to the thickness of the side wall (6), so that in the lowered latching position the recesses (13) and the carrier plate (8) the walls ( 6) Grip around on three sides.
- the lugs (12) are set back from the recesses (13). In the operating and rest position, the support plate (8) can be screwed and fixed to the wall (6).
- the brush block (7) with the carrier plate (8) can be lowered to such an extent that the brushes (16) come into contact with the
- each brush module (19) has only one circuit board (10) with one depending on
- slip ring layer on the top or bottom of the brush block (7) In the case of slip rings (3) on the top, the slip tracks (4) of which are arranged on the underside of the ring, the brush module (19) is lifted upwards into the latching position when it is inserted in kinematic reversal of the above-described embodiment.
- a brush module (19) can carry a plurality of boards (10) with brush blocks (6) arranged in parallel and at a distance above one another, which come into contact with a corresponding number of slip rings (3) by means of a common latching movement.
- several recesses (5) with lateral slots (11) can be provided for this.
- the latching and guiding function of the cutouts (13) on the wall (6) can be dispensed with.
- the cutouts (13) can be chosen to be correspondingly larger.
- Assembly principle of inserting and positioning the brush modules (19) in two separate and mutually preferably vertical movements can also be used in other forms of slip ring transmitters in which, for. B. the slip ring tracks (4) are arranged on the outer jacket of cylindrical carrier parts.
- the insertion movement of the brush modules (19) then takes place along the axis of rotation (18) and the subsequent positioning movement in the radial direction.
