Definitions

  • the invention relates to a device for guiding a drilling means with a positioning means, which serves to guide the drilling means against a surface, wherein the positioning means has a guide part through which the drilling means on a The axis of rotation can be rotatably fastened to the positioning means parallel to the working direction.
  • Devices of the type mentioned above are used to position a drilling means on a Surface of a surface to be worked on, for example a concrete wall.
  • precise positioning is required of the drilling means is difficult because a view of the drilling means in the area of the central axis of the drilling means is impossible.
  • DE 2 602 2308 describes a device for drilling with a drill bit and a center drill screwed coaxially into a shaft part of the drill bit.
  • the centering drill protrudes beyond the drill bit at the end in the direction of work a precise positioning of the drill bit.
  • a disadvantage of the known solution is that the center drill reduces the removal of the drill bit significantly reduced. This results in precise positioning for a user, however, a significantly longer drilling time.
  • DE69212478 T2 is a device for drilling with a shaft part having drill bit known.
  • the device also has one arranged on the shaft part Center drill that is used to position the drill bit.
  • the center drill is axially biased in the working direction by a wire spring.
  • a disadvantage of the known solution is that the device cannot be produced economically is and also does not ensure sufficient mining performance.
  • the object of the present invention is an economically producible device to create a drilling equipment that ensures high mining performance.
  • the device is also intended to ensure a large drilling depth.
  • the object is achieved in that the positioning means a Working direction openly designed receiving area for receiving the drilling means. Due to the at least partial arrangement of the positioning means radially on the outside On the one hand, drilling means ensures a simple constructive implementation of the device and on the other hand a high excavation capacity with a maximum drilling depth. Another advantage is that optionally by arranging the positioning means maximum stability the device is guaranteed, especially with drilling means with a large diameter. Especially when using drill bits as drilling means, the entire, formed by a wall of the drill bit, interior for receiving a drill core for Available, which ensures a maximum drilling depth. In addition, the Storage of the positioning means through the guide part on the drilling means a simple Handling of the device and the drilling means, since they are one unit when assembled form.
  • the positioning means is preferably axially counter to a spring force in the working direction compressible to ensure optimal guidance in any position during the drilling process. Due to the spring force in the working direction, even when the drilling means is removed from a drilled hole, a precise guidance of the drilling means opposite the Surface ensured.
  • the positioning means is telescopically compressible to a compact To ensure the outer contour of the device.
  • the positioning means preferably has one at the end on the working direction side at least one adhesive surface provided to prevent unintentional repositioning to avoid positioning on the surface.
  • the adhesive ensures high friction between the positioning means and the surface and is formed for example by rubber parts or nail-shaped bolt elements. In front the adhesive prevents everything from twisting or even turning the positioning means with the drilling means, which can be driven, for example, by a motor via a shaft.
  • the positioning means preferably includes the drilling means at least partially around the Protect drilling equipment from external influences. Also includes another Embodiment of the working direction end region the drilling means to an optimal Ensure stop surface on the surface, especially the drilling means against Secure tilting against the surface.
  • At least the end region of the positioning means on the working direction side is advantageous ring-shaped or optionally sleeve-shaped, for economical production of the positioning means.
  • the positioning means has at least one connecting element that the guide part connects slidably with the rest of the positioning means in the working direction. Thereby the guide member is immovably connected to the drilling means in the working direction remaining positioning means, however, displaceable relative to the attached drilling means in the working direction stored.
  • the guide part is preferably counter to the working direction by a spring element biased towards the rest of the positioning means to make it simple and economical Ensure manufacture of the device.
  • the drilling means 1 is a guide part 4, through which the positioning means 3 parallel to the axis of the working direction A is rotatably attachable to the positioning means 3.
  • the positioning means 3 has an essentially cylindrical receiving space 5 for receiving the drilling means 1 on.
  • the drilling means 1 has a sleeve-shaped drill bit at the end region on the working direction side 22 and then against the working direction A, a shaft part 21, which acts as a torque transmission means serves.
  • a shaft part 21 which acts as a torque transmission means serves.
  • the drill bit 22 has several evenly longitudinal recesses 24 distributed over their circumference.
  • the positioning means has a ring-shaped end region on the working direction side Stop plate 6 with a stop surface 7 oriented in the working direction A
  • a plurality of adhesives 8, in particular spike-like bolts, are arranged on the stop surface 7.
  • the adhesives 8 are, for example, by a screw connection with the stop plate 6 connected.
  • the stop plate 6 and the guide part 4 are formed by a plurality of bolts Connecting elements 9 connected to each other. With the stop plate 6 are the connecting elements 9 are each connected in a stationary manner by a screw connection.
  • the connecting elements 9 and the adhesive means 8 have compatible connecting means, especially screw connections, on to an economical manufacture and to ensure easy maintenance of the positioning means.
  • the guide part 4 has an annular guide plate 11 with a central through hole 12 on.
  • For axially displaceable mounting of the connecting elements 9 points the guide plate in the radially outer area several through guide holes 13 on.
  • In the through hole 12 is for the rotatable mounting of the shaft part 21 of the Drilling means 1 coaxial with the through bore 12, a bearing element 14 by means of bearings 18 rotatably arranged.
  • the Bearing element 14 is advantageously by a screw 16 with the shaft part 21 of the drilling means 1 connected to the guide plate 11.
  • a plurality of wire springs 15 are arranged, which are the two parts bias against each other.
  • the wire springs 15 are each on the corresponding connecting element 9 stored.
  • the connecting elements point at the end on the working direction 9 has a stop 17 which prevents the connecting elements 9 from sliding out of the Prevents guide holes 13 and thus the distance between the guide plate 11th and the stop plate 6 to a maximum distance, as shown in Figs. 1 and 3 is limited.
  • FIG. 1 and 2 show the device according to the invention with a drilling means 1 in the working position, in which the device is in the starting position and in 2 in a working position.
  • the drilling means 1 is first of the shaft part 21 via the bearing element 14 of the guide part 4 on the positioning means 3 attached. Then the bearing element 14 is, for example, in a not shown Tool holder of an electrically powered handheld machine tool detachably fixed. Subsequently, the positioning means 3 with the drilling means 1 on the surface placed, for example, to drill a hole for an electrical box. Is the positioning tool 3 precisely positioned, the drilling means 1, for example by the Hand tool, set in a rotational movement and the drilling means 1 with a Force applied in working direction A. If the force is sufficient, the drilling means 1 pressed against the spring force of the spring elements 15 against the ground and drills a recess.
  • the guide part 4 slides through the connecting elements 9 on the remaining positioning means 3 guided in the working direction A.
  • the on the stop plate 6 arranged adhesive 8 prevent the positioning means from rotating 3 with the drilling means 1. If the force acting in working direction A is less than the spring force of the spring elements 15, the guide part 4 moves with the drilling means 1 against Working direction A back to the starting position shown in Fig. 1.
