Device system and method for determining a depth of a bore that is produced with the device system

Abstract

A device system with a device stand, a drilling device arranged displaceably on the device stand for carrying out drilling and a feed device for displacing the core drilling device along the device stand. The feed device has a manual feed device, designed for example as a handwheel or a lever, and the device system has a control device for evaluating measured values. The feed device or the manual feed device e has a sensor for determining measured values, the measured values being used for evaluation and transmitted to the control device, and a starting point and/or an end point of the drilling being detected by the control device through a sudden change in drilling parameters. In a second aspect, the invention relates to a method for determining a depth of a bore, the bore being produced with the proposed device system.

Claims

1-13. (canceled)

14. A device system comprising: a device stand; a drill arranged displaceably on the device stand for carrying out drilling; and a feed for displacing the drill along the device stand, the feed including a manual feed; and a controller for evaluating measured values; the feed including at least one sensor for determining measured values, the measured values being usable for evaluation and being able to be transmitted to the controller, a starting point or an end point of the drilling being detected by the controller through a sudden change in further drilling parameters.

15. The device system as recited in claim 14 wherein a depth of a drilled bore is determinable using a transmission ratio and a number of revolutions of the manual feed, the number of revolutions of the manual feed being determinable on the basis of the measured values.

16. The device system as recited in claim 14 wherein determined or evaluated measurement data can be used for triggering functions of the device system.

17. The device system as recited in claim 14 wherein the manual feed is designed as a handwheel or as a lever.

18. The device system as recited in claim 14 wherein the controller is part of the drilling device or the feed.

19. The device system as recited in claim 14 wherein the sensor is designed as an acceleration sensor, gyro sensor or Hall sensor.

20. The device system as recited in claim 14 wherein a transmission of the measured values from the sensor to the controller takes place in a wired manner.

21. The device system as recited in claim 14 wherein a transmission of the measured values from the sensor to the controller takes place in a wireless manner.

22. The device system as recited in claim 14 wherein the drill has an electric motor.

23. The device system as recited in claim 14 further comprising a display for displaying determined or evaluated data.

24. The device system as recited in claim 23 wherein the display is part of the drill or the feed.

25. The device system as recited in claim 23 wherein the manual feed has the sensor.

26. A method for determining a depth of a bore, wherein the bore is produced with the device system as recited in claim 14, the method comprising the steps of: a) recording at least one drilling parameter of the device system, b) deriving a starting point and/or an end point of the drilling from the drilling parameters recorded under a), c) recording measured values via the sensor, d) transmitting the measured values to a controller, e) determining a number of revolutions of the manual feed from the measured values recorded under c), f) determining a depth of a bore from the number of revolutions of the manual feed and a transmission ratio.

27. The method as recited in claim 26 wherein the depth of the bore is displayed on a display of the device system.

28. The method as recited in claim 26 wherein at least one other function of the device system is triggered on the basis of the depth of the bore.

DETAILED DESCRIPTION

[0045] FIG. 1 shows an exemplary embodiment of the invention. In particular, FIG. 1 shows a device system with a drilling device (1), a device stand (2) and a feed device (3). The feed device (3) comprises a manual feed device (4), which may be designed as a handwheel or as a lever. In the embodiment of the invention depicted in FIG. 1, a manual feed device (4) designed as a handwheel is shown. The drilling device (1) may be attached to the drilling stand (2), the feed device (3, 4) being arranged between the drilling device (1) and the device stand (2). The bottom left of the drawing shows the drill bit (without a reference number), with which for example a drill core can be cut from a substrate, a wall or a ceiling. FIG. 1 also shows a possible arrangement of the control device (5) on the drilling device (1). The control device (5) may preferably be part of the drilling device (1) or the feed device (3). A motor (7) and display (8) are shown solely schematically.

[0046] FIG. 2 shows a preferred embodiment of the invention in which the manual feed device (4) is designed as a lever. FIG. 3 shows a preferred embodiment of the invention in which the manual feed device (4) is designed as a handwheel. The at least one sensor (6), which is used in the context of the invention for determining measured values, such as angles of rotation, is preferably located in each case at a pivot point or in an axis of rotation of the lever or of the handwheel.
