Definitions

  • the present invention relates to a hand assembly tool for connecting a motor flange with and for disconnecting the motor flange from a hand tool transmission.
  • the hand tool gear for example, be a gearbox of a hammer drill, combi hammer or a feed device for a core drill.
  • the motor flange has at least one spring tab by means of which the motor flange can be locked or unlocked on the hand tool transmission.
  • the invention also relates to a system with a hand assembly tool and with a motor flange.
  • a manual assembly tool of the type mentioned for example, a pair of pliers or the like, which is conceivable unsuitable for connecting or disconnecting a motor flange of a hand tool gear.
  • the object is achieved in that the manual assembly tool can be attached to the motor flange in a fitting position coaxial with an axis of rotation of the motor flange, such that the spring tab is received within a volume of the manual assembly tool.
  • the hand-assembly tool has at least one in-volume ramp adapted to deflect the spring tab of the motor flange axially of the rotation axis of the hand-held mounting tool about the rotational axis of the motor flange and toward a release position, and the motor flange via a ramp formed on the ramp To unlock the rotary drive.
  • the invention includes the recognition that a hand tool transmission is typically supplied by the supplier as an assembly with a mounted motor flange. Since a hand tool motor can typically only be mounted on the motor flange from the concealed rear side, the motor flange must first be dismantled. For this purpose, two spring tabs, which may consist of plastic, raised and turned the motor flange until it can be removed axially from the hand tool gearbox.
  • the invention further includes the knowledge that by manually lifting and holding the spring tabs with the fingers while rotating the motor flange handling is extremely difficult and unsuitable for series assembly. Furthermore, there is a risk that the typically made of plastic spring straps are overstretched and thus pre-damaged. This can disadvantageously lead to a failure of a hand tool in which the motor flange is installed.
  • a manual assembly tool is provided in the sense of an assembly aid, which serves to connect and disconnect the motor flange easily and quickly with a hand tool transmission.
  • the operation of the manual assembly tool is done manually, that is, the manual assembly tool is placed by hand on the motor flange and fastened by means of a rotary motion on an end face of the hand tool gear.
  • the manual assembly tool is both simple and safe to handle.
  • the rotational drive is designed as a step.
  • the step can serve as a stop for the spring tab and / or as a stop for a rigid portion of the spring tab.
  • a rotational drive configured as a step may divide the ramp into a lower ramp section and an upper ramp section.
  • the ramp is formed spirally with respect to the axis of rotation of the motor flange.
  • the upper portion is adapted to deflect the spring tab.
  • the lower ramp portion may be configured to support a rigid portion, via which the spring tab is formed on the motor flange, in the course of rotation of the manual assembly tool.
  • a two-part ramp so on the one hand, the deflection of the spring tab, which is required to unlock the motor flange cause.
  • the rigid section of the spring clip can be supported by a two-part ramp, so that a particularly safe and damage-free removal of the motor flange is possible.
  • the lower ramp section has a smaller pitch than the upper ramp section.
  • the lower ramp section and / or the upper Ramp section can have a progressive slope.
  • a progressive pitch is in this case related to a rotation which serves to release the motor flange of the hand tool gear.
  • the manual assembly tool is designed such that a counterclockwise rotation of the manual assembly tool about the axis of rotation of the motor flange means a release of the motor flange.
  • the manual assembly tool is cylindrical.
  • the diameter of the cylindrically shaped manual assembly tool is preferably twice as large as the height of the cylindrically shaped manual assembly tool.
  • the diameter of the cylindrically shaped hand assembly tool is between 7 cm and 10 cm.
  • the height can be between 2 cm and 4 cm.
  • the diameter of the manual assembly tool is greater than the diameter of the motor flange, preferably based in each case on the intended rotation axis.
  • the manual assembly tool made of plastic or has such.
  • a central support ring is formed in the manual assembly tool, which serves as a sliding bearing between the hand-mounting tool and the motor flange.
  • the central support ring may be provided, for example, by cropping a surface of the manual assembly tool. This can be realized, for example, by one or more arcuate sections or recesses on the top of the hand-assembly tool.
  • the manual assembly tool has two ramps, preferably exactly two ramps.
  • the ramps can be arranged diametrically opposite each other.
  • the motor flange has two, in particular exactly two spring tabs, which can be arranged diametrically opposite one another.
  • the spring tab may be locked to a corresponding to the spring tab counterpart of the hand tool gear when the motor flange is attached to the manual assembly tool transmission.
  • the spring tab and the corresponding counterpart preferably form a connection in the sense of a bayonet closure.
  • the object is achieved by a system with a hand-held tool as described above and with a motor flange, wherein the motor flange has at least one spring tab, by means of which the motor flange locks on the hand tool gearbox or can be unlocked.
  • the system may be further developed by the features described with reference to the manual assembly tool.
  • FIG. 1 an inventive hand assembly tool 10 is shown in a perspective view from above.
  • the manual assembly tool 10 is provided for connecting a motor flange 20 with and for disconnecting the motor flange 20 from a hand tool transmission 30.
  • the motor flange 20 is attached to the hand tool gear 30.
  • the manual assembly tool 10, which is presently cylindrical, has on an outer periphery a handle portion 17 which is intended to be held by a human hand.
  • the handle portion 17 is grooved to facilitate the operation.
  • a central support ring 15 is formed in the manual assembly tool 10, which serves as a sliding bearing between the manual assembly tool 10 and the motor flange 20 when the hand-mounting tool 10 is placed on the motor flange 20.
  • the central support ring 15 rests on a support region 25 of the motor flange 20.
  • the motor flange 20 has exactly two spring tabs 21, 23.
  • the spring tabs 21, 23 are arranged diametrically opposite each other.
  • the spring tabs 21, 23 are integrally formed on the motor flange 20 via a respective rigid section 21 ', 23'.
  • the motor flange 20 is made of plastic.
  • the spring tabs 21, 23 are axially deflectable to the axis of rotation R of the motor flange 20. This is indicated by respective arrows on the first spring tab 21 and the second spring tab 23. An axial deflection of the spring tabs 21, 23 is elastic. In FIG. 1 are the spring tabs 21, 23 of the motor flange 20 in the non-deflected state.
  • the hand tool gear 30 has at its periphery to the spring tabs 21, 23 corresponding counterparts 31, 33, by means of which the motor flange 20 is locked to the hand tool gear 30 in the sense of a bayonet lock. It is in FIG. 1 the locked state shown.

  • the corresponding counterpart 33 is located between the second spring clip 23 and the second rigid section 23 '.
  • the direction of rotation DR in which the manual assembly tool for releasing the motor flange 20 has to be rotated in the counterclockwise direction, is designated by the corresponding arrow.
  • FIG. 3 now shows the embodiment of FIGS. 1 and 2 , wherein a rotation DR of the manual mounting tool 10 has taken place about the rotation axis R in the direction of a release position LP. It shows FIG. 3 not the final release position, but a rotational position of the manual assembly tool 10 just before this assumes the release position.
