Definitions

  • the present invention relates to a device system with a device for fastening a tool device to a device stand with the features according to the preamble of patent claim 1.
  • EP 2 067 578 A2 discloses a stand-mounted device system having a device stand, a guide carriage which is displaceable in a feed direction along the device stand, and a tool device, which is detectable by means of a first and second coupling means on the guide carriage having.
  • the first coupling device designed as a machine coupling part is arranged on the tool device and comprises a first and a second engagement element.
  • the first and second engagement members are formed as bolts that are at least partially exposed circumferentially.
  • the second coupling device designed as a slide coupling part is arranged on the guide carriage and comprises a first and a second rear engagement element which engage behind or embrace the first and second engagement element in a locking position.
  • the first rear engagement element is rigidly fixed to the carriage coupling part and the second engagement element is adjustable about an axis of rotation via an eccentric mechanism.
  • the pivotally formed second rear engagement element has guide surfaces which are intended to cooperate with correspondingly designed guide surfaces of the first coupling device.
  • the guide surfaces of the first coupling device must enable a pivoting movement of the second rear engagement element and, on the other hand, position the second engagement element as accurately as possible in the locking position. Both conditions can not be fulfilled simultaneously.
  • high forces and torques occur on, which must be transmitted via the bolts from the tool to the device stand, so that the bolts must be made very thick.
  • the object of the present invention is in contrast to further develop a device system of the type mentioned in that the tool device can be positioned in the locking position with a higher accuracy to the device stand.
  • the forces and torques occurring during machining with the tool device should be reliably transmitted from the tool device to the device stand.
  • the first and second engagement element of the first coupling device are integrated into a one-piece adapter plate, which is connected to the tool device via a connection device or integrated into the tool device.
  • the adapter plate has a first and second guide surface, which are aligned in the locking position on a first and second mating guide surface, which are provided on the guide carriage.
  • the formation of counter-guide surfaces, which are firmly connected to the guide carriage, has the advantage of a higher positioning accuracy in the locking position.
  • the first and second mating guide surface are formed as parallel surfaces of a guide element which is fixed to the guide carriage.
  • a separate guide element has the advantage that the separate guide element can be made wear-resistant.
  • the first and second mating guide surface are integrated as parallel surfaces in a housing of the guide carriage.
  • the integration of the counter guide surfaces in the housing of the guide carriage has the advantage that no separate guide element is required. The exact alignment of the counter-guide surfaces takes place in the manufacture of the housing.
  • one of the counter-guide surfaces is integrated in a housing of the guide carriage and the other of the counter-guide surfaces is provided on a guide element which is connected to the guide carriage.
  • the first and second mating guide surface are particularly preferably provided on a housing part of the guide carriage. If the first and second mating guide surfaces are arranged on the same housing part, dimensional deviations between the housing parts have no influence on the accuracy of the positioning.
  • the adapter plate has one or more contact surfaces, which are positively connected to a machine housing of the core drill. Due to the positive connection of the adapter plate and the machine housing via the contact surfaces, the power transmission is supported by the core drill on the guide slide or the drill stand.
  • the first rear engagement element and / or the second engagement element are formed from one or more punched parts.
  • Stamped parts have the advantage that they can be produced cheaply, with repeatable accuracy.
  • the stampable sheet thickness is limited, a plurality of stampings are joined together to form a sufficient clamping surface on the first and second rear engagement element.

  • the drill stand 3 is arranged on a base 8 and consists of a foot plate 9, which can be fastened by means of a fastening device 10 to the substrate 8, and a guide rail 11, which is connected by means of a connecting device 12 with the foot plate 9.
  • the core drilling device 2 is arranged on the drill stand 3 via a guide carriage 13 and can be displaced by means of a feed device 14 along the guide rail 11 in a feed direction 15 .
  • the feed device 14 comprises a manual drive device 16 and a transmission device 17, which is coupled to the manual drive device 16 and the guide carriage 13 and is designed as a feed pinion.
  • the movement of the manual drive device 16 is transmitted to the feed pinion 17 and converted into a displacement of the guide carriage 13 and the coupled core drilling device 2 along the guide rail 11.
  • the guide rail 11 is designed as a rack with a contour element 18 which can be brought into engagement with a corresponding mating contour element 19 of the transmission device 17.
  • FIGS. 2A B show a device for fastening the core drilling device 2 to the drill stand 3 consisting of a first coupling device 21 which is arranged on the core drilling device 2 ( Fig. 2A ), and a second coupling device 22, which is arranged on the guide carriage 13 ( Fig. 2B ).

On a front side opposite the rear side, the adapter plate 23 is in contact with the machine housing 4 of the core drilling apparatus 2.
  • the adapter plate 23 is inserted into a recess 28 of the machine housing 4 and connected by four screw 29 positively to the machine housing 4.
  • the screw 29 are dimensioned in number and size so that the forces occurring during operation can be transmitted via the contact surface.
  • the recess 28 in the machine housing 4 is designed so that the adapter plate 23 is positively connected to the machine housing 4.
  • the tolerances of the recess 28 are designed so that the orientation of the machine tool is guaranteed even at very high loads.
  • the adapter plate 23 includes first and second guide surfaces 30, 31 which are parallel to each other and cooperate in the locking position with corresponding mating guide surfaces disposed on the guide carriage 13.
  • Fig. 2B shows a section of the guide carriage 13 with the mounted on the carriage 13 second coupling means 22.
  • the second coupling means 22 includes a first rear engaging member 33 and a second rear-engaging element 34 which are engageable with the first and second engaging member 24, 25 into engagement. In the locking position, the first rear engagement element 33 engage with the first engagement element 24 and the second engagement element 34 engages with the second engagement element 25.
  • the first rear engagement element 33 is connected in a rotationally fixed manner to the guide carriage 13, and the second engagement element 34 is designed to be rotatable about an axis of rotation 36 by means of an adjustment device 35 .
  • the adjusting device 35 comprises an eccentric pin 37 and a lever which is connected via a receiving element 38 in the form of a square with the eccentric pin 37.
  • the guide carriage 13 is formed in two parts from a first housing part 39 and a second housing part 40 .

  • the first mating guide surface 42 is formed as an outer surface of a guide element 44 in the form of a feather key, and the second mating guide surface 43 is integrated into the second housing part 40 of the guide carriage 13.
  • the first and second mating guide surface may be integrated in a housing part of the guide carriage 13, or the first and second mating guide surface may be opposed outer surfaces of a guide member.
  • FIGS. 3A- C show the first rear engagement element 33 (FIG. Fig. 3A ), the second rear engagement element 34 (FIG. Fig. 3B ) and the first and second engaging elements 24, 25 (FIG. Fig. 3C ).
