Definitions

  • the present invention relates generally to an adaptor for rotating tools for mounting in a drilling machine and is more particularly concerned with a new and improved quick release drive arbor for rotating tools such as hole saws and the like.
  • US patent No. 4,148,593 discloses an arbor assembly 100 including a quick disconnect arbor 101 comprising a thrust member 102 having a selected working position (as shown in Fig. 1) and a release position. The two positions are established by a ball 103 in the thrust member 102 being pushed against the arbor body, towards a hollow 106 in the working position and towards a hollow 107 in the release position, by means of a spring loaded ball 104.
  • the spring loaded ball 104 cooperates with a set screw 105.
  • the thrust member slides axially beyond its working and release positions and furthermore that the tool, a saw cup, when desired quickly and easily is released from the arbor in order to either exchange the tool with a new, similar one, or another tool in a different size.
  • the saw cup will vibrate and wobble because it is not sufficiently locked to the thread. This results in inaccurate holes and shortened life-time of the . tool and the drilling machine.
  • the main objects of the present invention are to provide a new and improved quick release arbor having means for reducing hole saw wobbling and furthermore to provide such an assembly having a minimum of parts, and not needing cumbersome tools for handling the arbor, e.g. a large wrench .
  • an adaptor for mounting a rotating tool in a drilling machine said adaptor having at least one locking member, according to independent claim 1.
  • the adaptor comprises an arbor body having a first end with a shank for mounting to a drill chuck and a second end with a thread for mounting the tool, as well as a thrust member, which is arranged on the arbor body.
  • the thrust member is movable in an axial direction but not in a rotational direction relatively to the arbor body.
  • At least one driving pin is fixed to the thrust member, preferably rotatably, and directed towards the second end of the arbor body for engaging the tool.
  • the at least one adjustable locking member is arranged in the thrust member and movable in a direction substantially perpendicular to the axis of the arbor body.
  • At least one biased surface is arranged on the arbor body adjacent to the adjustable locking member.
  • the at least one adjustable locking member engages the at least one biased surface when the locking member is moved in a direction towards the arbor body, preferably towards the center of the arbor body, and pushes the thrust member towards the second end of the arbor body.
  • a spring loaded ball in a thrust member and mating grooves in an arbor define a quick release arbor.
  • the arbor is combined and cooperates with a locking member in a thrust member arranged around the arbor.
  • the arbor transmits torque from a drilling machine to a tool lixed to said arbor.
  • the locking member is preferably a screw.
  • the locking member When activated, the locking member pushes the thrust member abutting the tool towards the tool, thus both locking the thrust member and reducing vibrations and wobbling due to the tool being more precisely fixed to the arbor by eliminating slack in a thread of said tool towards a threaded end of said arbor on which the tool is screwed.

  • the thrust member 7 is in a preferred embodiment designed as a single unit with a central partially hexagonal aperture 8 for receiving the arbor body 2.
  • the hexagonal aperture 8 engages a
  • the aperture 8 is preferably circular in shape at the top end, i.e. the end closest to the threaded portion 4, in order to provide a block as to restrain the thrust member 7 from sliding too
  • the thrust member 7 is preferably mounted on the arbor body 2 in a spring loaded manner, wherein the thrust member 7 is locked in either a rear position or a
  • a chamber 15 in the thrust member 7 being in communication with the central aperture 8 of the thrust member 7 accommodates a spring loaded ball 10 which is continuously urged towards the arbor body 2.
  • the arbor body 2 is provided with grooves 11 to define the rear and forward positions of the thrust member 7, whereby the forward position is even called the working position and the rear position is even called the release position.
  • Grooves 11 are either located in the hexagonal portion of arbor 2 or in the non-hexagonal portion towards the chuck- end of arbor 2, as shown in e.g. Fig. 4A. In operation, the spring loaded ball 10 is received in the grooves 11 and locks the thrust member 7.

  • two driving pins are used in order to distribute the load from the rotation of the adaptor tool 1 when transferring torque from the drilling machine to the hole saw 5.
  • more than two driving pins 12 may of course be used.
  • a noteworthy and novel feature of the present invention is an adjustable locking member 13 which is arranged in a threaded hole 14 in the thrust member 7.
  • the adjustable locking member 13 is preferably in form of a small socket head cap screw that mates with the threaded hole 14 in the thrust member 7.
  • the adjustable locking member 13 may also be in form of an ordinary screw or a threaded pin.
  • the threaded hole in the thrust member 2 is aligned in a direction substantially perpendicular to the axis of the arbor body 2.
  • the threaded hole may, however, as shown in the embodiment shown in Figs. 5 and 8C, be somewhat tilted so that the adjustable locking member 13 engages the arbor body 2 in an angle being less than 90 degrees with respect to the axis of the arbor body 2 in a direction towards the threaded portion 4.
  • adjustable locking member 13 By turning the adjustable locking member 13, e.g. by means of an offset screwdriver for a hexagon socket or torx head screw, the threading in the hole and on the screw will cause adjustable locking member 13 to move in a direction towards or away from the arbor body 2 depending on the direction of rotation.
  • the locking member 13 has thus a rest position and a locking position, whereby the locking member 13 is in its rest position when it is not engaged in the arbor body 2.
  • the arbor assembly according to the invention is operable both with the locking member 13 being engaged in the arbor body, i.e. the locked working position of the locking member, or in the rest position of the locking member, i.e. the locking member not being engaged in arbor body 2. Therefore the arbor may be operable quickly when a tool is installed, with the arbor assembly working in operating mode with the locking member 13 in its rest position, however with less accuracy than in the locked working position.
  • the locked working position of thrust member 7 is in addition to its release and working position defining the way operation of the adaptor according to the invention. In this way, the adaptor according to the invention can quickly be used without locking, but it has the advantageous possibility of a locking position.
  • Fig . 4B shows a preferred embodiment with the biased surface being defined by a conical hollow 19.
  • the arrangement is thus preferably self centering when tightening the locking member 13 towards the locking position due to an appropriate mating conical front side of matching locking member 13 13.
  • locking member 13 is not directed towards the center of arbor body 2, but instead e.g. to a beveled groove 18 in arbor body 2 as shown in Fig. 4C , hereby the beveled groove is arranged in a direction substantially rotational around the longitudinal axis of arbor body 2.
  • At least one biased surface is arranged on the arbor body adjacent to the adjustable locking member.
  • said biased surface 17 engaged by the locking member is part of a conical hollow 19 which center axis is slightly displaced with respect to the working position towards said second end, whereby the biased surface 17 is situated on the hexagonal part of arbor body 2, adjacent to locking member 13.
  • the biased surface might as well be situated on other areas of the arbor body.
  • the at least one adjustable locking member engages the at least one biased surface when the locking member is moved in a direction towards tne arbor Joo y an pusnes the thrust member towards the second end of the arbor body.
  • biased surface 17 is arranged in such a way that when locking member 13 is moved towards the arbor body, thrust member 7 is pushed towards the tool 5, whereby thrust member 7 is in the working position abutting tool 5 being installed on the threaded part 4 of arbor body 2 , and locking members 12 being engaged in the respective openings in tool 5 for transferring rotational force from the drilling machine to the tool 5.
  • thrust member 7 is further pushed against tool 5, whereby slack in the thread 4 is further eliminated and the arbor 2 is in a locked working position.
  • the biased surface being engaged by the locking member is part of a conical hollow 19 which center axis is slightly displaced with respect to the working position towards that end of arbor body 2 on which the tool is installed.
  • the tool is mounted by screwing the threaded hole 6 of the rotating tool 5 onto the threaded portion 4 of arbor body 2 until it reaches the hexagonal portion 22 of arbor body 2.
  • locking member is in the release position.
  • locking member 7 is pushed towards the working position and driving pins 12 are aligned with the mating holes in tool 5 by twisting tool 5 to an appropriate position.
  • the working position of thrust member 7 is such that the thrust member abuts tool 5 and exerts a certain pressure on the threaded hole 6 and the threaded portion 4, thus eliminating thread slack, offering the above mentioned advantages.
  • FIGs 3A and 3B illustrate an adaptor for mounting a rotating tool in a drilling machine according to another preferred embodiment of the present invention.

  • Drill 16 is inserted into a central bore 23 in arbor body 2 and locked by moving drill locking means 20 towards the center of arbor body 2 and pushing it against drill 16.
  • the Arbor shown in Fig. 3A has the thrust member 7 in the release position. In this position, drill locking member 20 is tightened so that thrust member 7 fits over member 20 when being moved to the working position shown in Figure 3B. Thus drill locking member 20 is secured when thrust member 7 is moved to the working position.
  • Figs. 7A to 7D show different perspective views of the thrust member 7 according to the preferred embodiment shown in Figs. 3A and 3B.
  • a thrust member 7 with two locking members 13 is illustrated.
