Description

DETAILED DESCRIPTION

[0084] The first embodiment of the collecting device (10) according to the principles of the present disclosure and the collecting container (11) according to the principles of the present disclosure as shown in FIGS. 1A-1D is provided between the workpiece spindle (22) and the tool spindle (21) of a machine tool (20). Workpiece spindle (22) and tool spindle (21) can be positioned relative to each other in an x-y plane.

[0085] The collecting device (10) comprises a container (11) with four side surfaces A, B, C, D, an upper side E and an underside F. The side surfaces A and C, the side surfaces B and D as well as upper side E and underside F are each arranged opposite one another. The edge lines along the side surface B, C are of rounded design, i.e. the collecting container has a rounded corner here (see also FIG. 2C, D).

[0086] The container (11) has four openings (12, 13, 14, 16): a first opening (12) in side surface A of the container (11) for receiving the at least one tool spindle (21); a second opening (13) for receiving the workpiece spindle (22), wherein the second opening (13) extends over the side surfaces B, C of the container (11); a third opening (14) for receiving a collecting bottle (15) for collecting machining suspension, and a fourth opening (16) with outwardly pointing suction nozzle (17) for mounting a suction hose.

[0087] The first opening (12) for receiving the at least one tool spindle (21) is a circular opening (see FIG. 1C).

[0088] The second opening (13) for receiving the workpiece spindle (22) is an elongate opening which extends in an arc-shaped manner over the (rounded) edge over the side surface B and side surface C of the container (11) (see FIG. 1A, but also FIGS. 2D, 2E).

[0089] For example, the second opening (13) for receiving the at least one workpiece spindle (22) can also be described as a slot that extends in an arc-shaped or semicircular manner over the two side surfaces. The second opening (13) for receiving the at least one workpiece spindle can also be designed and described in such a way that the slot-shaped opening extends parallel to the underside and upper side of the collecting container (11) and two semicircles each form the end of the opening (a first semicircle in the side surface B and a second semicircle in the side surface C). The geometric design of the second opening (13) for receiving the at least one workpiece spindle thus provides for a movement of the workpiece spindle (and of the workpiece to be polished) in an x-y plane (relative to the tool spindle); see FIG. 1B.

[0090] A brush strip (18) is provided along the edges of the second opening (13) for receiving the workpiece spindle (22) (see FIG. 1A).

[0091] The third opening (14) for receiving (and fastening) the collecting bottle (15) is provided in the underside F of the collecting container, see FIGS. 1A, 1C. The third opening (14) has an internal thread into which an external thread of the collecting bottle engages to form a releasable connection. The machining suspension collected in the collecting container during the machining of the ceramic workpiece can flow out of the container into the collecting bottle (15) automatically by means of gravity.

[0092] For this purpose, as shown in FIGS. 1A, 1C, the underside F of the container (11) extends with an inclination towards the third opening (14) for the collecting bottle (15), so that the polishing suspension can automatically flow out of the container (11) by gravity from the underside F through the third opening (14) into the one collecting bottle (15). The inclination of the underside F of the collecting container (11) is between 15 and 30.

[0093] The fourth circular opening (16) with suction nozzle (17) for mounting a suction hose can be provided on the upper side E or also on the edge that connects the (front) side surface D and the upper side E. In the latter case, the suction nozzle extends diagonally upwards. In this case, the suction nozzle (17) extends at an angle of 15-30 (with respect to the side surface D) (see FIGS. 1A, 1C).

[0094] According to the second embodiment shown in FIGS. 2A-E, the collecting container (11) has, in addition to an inclination of the underside F of the collecting container, a protrusion (19) or a projection which is flange-mounted to the collecting container (and correspondingly projects from the collecting container). The third opening (14) for the collection bottle (15) is provided in this protrusion (19).

[0095] As can be seen in FIG. 2A, B, E, the protrusion (19) extends with an inclination towards the third opening (14) for the collecting bottle (15), so that the polishing suspension can automatically flow out of the container (11) by gravity from the underside F into the flange-mounted protrusion (19) and into the collecting bottle (15).

[0096] The flange-mounted protrusion (19) extends along the entire length of the contact line of side surface D and underside F of the container (11).

[0097] The flange-mounted protrusion (19) is inclined at an angle of 40 to 50 with respect to the side surface D and with respect to the underside F likewise at an angle of 40 to 50 (see FIG. 2A, B, E).

[0098] The second construction or second embodiment of the collecting container with the protruding portion or protrusion can also be described as follows (see FIG. 2A, B, E).

[0099] The (front) side surface D is shortened by an amount m and the underside F by an amount n. The corners of the side surface A, C, which meet the side surface D and the underside F, are removed by the amount m and amount n, and are thus adapted correspondingly to the shortened side surface D and underside F. The collecting container now has an elongate (triangular) opening that extends along the shortened side surface D and underside F and from the side surface A to the side surface C.

[0100] The housing or housing portion is flange-mounted or placed at a predetermined angle (with respect to the side surface D and the underside F) along the elongate opening, extending between the shortened side surface D and underside F and from the side surface A to the side surface C.

[0101] The third opening (14) for fastening the collecting bottle (15) can be provided at any position of the inclined flange-mounted protrusion. Preferably, the at least one third opening for fastening the collecting bottle is provided on the right-hand side of the housing (when looking at the front side surface D) (see FIG. 2A, B, E).

[0102] The fourth opening (16) with suction nozzle (17) for mounting a suction hose is provided on the (front) side surface D of the container (11) (see FIG. 2A, B).

[0103] According to the third embodiment shown in FIG. 3, the collecting device (10) in turn consists of a container (11) with four side surfaces A, B, C, D, an upper side E and an underside F. The side surfaces A and C, the side surfaces B and D as well as upper side E and underside F are each arranged opposite one another. The edge lines along the side surface B, C are of rounded design.

[0104] The container (11) likewise has four openings (12, 13, 14, 16): a first opening (12) in side surface A of the container (11) for receiving the at least one tool spindle (21); a second opening (13) for receiving the workpiece spindle (22), wherein the second opening (13) extends over the side surfaces B, C of the container (11); a third opening (14) for receiving a collecting bottle (15) for collecting machining suspension.

[0105] The fourth opening (16) for connection to a suction device here is of slot-shaped design. The slot-shaped opening (16) extends along the length of the side surface D of the collecting container. This slot-shaped opening is configured to connect or mount a suction device, wherein the connection here is provided as a suction channel (17a).
