Definitions

  • the invention relates to a power tool, in particular an angle grinder, with a drive motor accommodated in a housing, which drives a rotor shaft, with a tool spindle having a tool holder, which is connected to the rotor shaft by an angular gear which is accommodated in a gear head, with a one Bearing plate having a spindle passage in which the tool spindle is rotatably received, the bearing plate having a receiving flange on which a protective hood can be rotatably mounted, the dismantling of which from the receiving flange is at least made more difficult by a securing device.
  • a coding is usually formed between the mounting flange of the mounting plate and the protective hood - and preferably also in the case of the present power tool to dismantle.
  • axial grooves formed on the receiving flange.
  • radial projections which are formed on the inside of a hollow cylindrical assembly flange of the protective hood engage in these axial grooves.
  • the assembly position generally corresponds to a position that usually does not serve as a working position.
  • the protective hood can then be rotated and locked in various working positions by means of a pawl.
  • Such protective hoods are intended to protect the user of the power tool from injuries caused by the sparks or similar particles produced when the power tool is used.
  • the protective hood must ensure that if the insert tool breaks, the protective hood can withstand the fragments of the insert tool that hit the protective hood at very high speeds.
  • a stop component that is screwed to the bearing plate is intended to prevent the user can easily remove the protective hood from the angle grinder.
  • the stop component can be screwed into the bearing plate through a threaded connection, but cannot be removed from it without first dismantling the bearing plate.
  • the securing device is selected from a group comprising at least one securing pin received in the receiving flange, a locking ring preferably secured by a latching connection or by a press connection on the receiving flange, a comprises a securing plate screwed to the bearing plate by a plurality of securing screws, a securing clip fastened to the bearing plate and a securing tab formed on the protective hood.
  • the at least one securing pin can be inserted into a pin receptacle formed on the receiving flange after the protective hood has been mounted on the receiving flange.
  • the at least one locking pin can be inserted into the pin receptacle.
  • the locking pin can be inserted into the pin receptacle in such a way that the locking pin still protrudes into the axial groove, whereby the corresponding axial groove on the receiving flange is blocked and the protective cover is prevented from being dismantled, since the respective radial projection is blocked by the locking pin.
  • the locking pin is hammered into the pin holder.
  • the securing pin can simply be inserted from the outside through the passage, which is preferably formed on a mounting flange of the protective hood, into the pin receptacle.
  • the locking pin is inserted from the inner circumference of the receiving flange into the pin receptacle which opens into the axial groove. With this type of assembly, too, the locking pin naturally protrudes through the pin receptacle into the axial groove in order to block the axial groove and thus prevent the protective cover from being dismantled.
  • the dismantling of the locking pin can be made even more difficult if the pin receptacle is designed as a blind hole. It is therefore not possible for the user to knock the locking pin through the pin receptacle in order to dismantle the protective cover from the bearing plate. Rather, the user would have to drill out the locking pin for dismantling. Therefore, if the protective cover has to be changed, it is necessary in this case to exchange the bearing plate together with the protective cover.
  • the securing device comprises a securing cap which is secured to the bearing plate by the at least one securing pin.
  • the at least one securing pin can only be removed from the axial groove if the securing cap has been destroyed beforehand, which would be noticed when checking the power tool.
  • the securing cap has at least ring segment-like projections on the side facing away from the tool holder. These projections can on the one hand be at least partially penetrated by the locking pin and on the other hand a stop for the Provide locking pin, so limit its depth of insertion into the pin receptacle and at the same time ensure that the protective cover can only be removed from the bearing plate if the locking cap is mechanically destroyed beforehand or if the locking pins have been drilled open.
  • the securing device is designed as a securing ring, it has been shown to be advantageous if the securing ring is assigned a radial collar on which securing extensions are formed.
  • the axial collar initially provides a stop surface which, during assembly, provides a limitation of the securing ring on the receiving flange.
  • the securing extensions can be received in at least some of the axial grooves that are formed in the receiving flange.
  • the retaining ring is preferably received at least partially on the inside of the receiving flange, whereby its assembly is facilitated.
  • the securing ring also ensures that the axial grooves are at least partially blocked, as a result of which the protective hood cannot be removed from the receiving flange.
  • the dismantling of the protective hood can also be prevented very easily by a locking ring which is secured to the receiving flange by a latching connection or by a press connection.
  • a latching connection In order to fasten the securing ring to the receiving flange, it has proven to be advantageous for the formation of a latching connection if latching lugs are assigned to the securing ring. In particularly preferred embodiments, these are formed on the securing projections which engage in the axial grooves.
  • the locking lugs engage in locking seats which, in a preferred embodiment, are attached to the receiving flange in the Area of the axial grooves are formed.
  • a very simple securing of the protective hood on the power tool can also be implemented by means of the securing plate, which is screwed to the bearing plate by several securing screws.
  • the securing plate is screwed to the bearing plate from the side facing away from the tool holder. This further increases the protection against unauthorized dismantling of the protective hood, since the bearing plate must first be dismantled in order to dismantle the protective hood.
  • the invention also provides for the securing plate to be attached by forming.
  • riveting punch riveting, clinching (clinching, toxening), caulking and crimping have proven to be advantageous.
  • Further options for attaching the securing plate are gluing, welding, in particular laser welding, vulcanization or injection molding, in order to make the dismantling of the securing plate even more difficult.
  • the locking screws used for the screw connection have a screw lock to prevent unauthorized loosening.
  • This can be done, for example, by a special shape of the screw head, which allows the locking screw to be screwed into the screw receptacle but prevents it from being loosened Tool holder of the screw head is used, or can be guaranteed by a special screw head that is sheared off by the locking screw when a limit torque is exceeded.
  • a centering and / or a centering collar is formed on the bearing plate and / or on the securing plate.
  • the centering comprises an axial collar which is formed on the bearing plate. The securing device can then be placed on this axial collar.
  • the securing plate is assigned securing wings which at least partially cover the protective hood.
  • the overlap can particularly preferably take place in an area at which no axial groove of the coding opens, which makes it possible for the user to check the alignment of the protective hood relative to the receiving flange in a very simple manner.
  • the securing wings are connected to one another by a locking ring.
  • This embodiment can in particular also be used with a bearing plate, the receiving flange of which is formed without coding on the outer circumference. This makes it possible to dispense with the design of a coding, which has a positive effect on the manufacturing effort.
  • the protective hood can therefore simply be placed on the mounting flange in any orientation. The axial position of the protective hood on the bearing plate is then fixed by the securing wings or the closing ring of the end plate.
  • the securing clip of the securing device is assigned a radially adjustable securing lug which can be moved into an expression that is formed on the protective hood. This is preferably formed on the mounting flange of the protective hood. The expression points radially outwards. As a result, the safety clip can simply move into the expression when the protective hood is mounted on the receiving flange and the protective hood is in the mounting position. If the axial groove and the radial projections of the coding are aligned with one another, then the securing clip and the expression are also opposite one another.
  • the securing lug is preferably attached to the securing clip only on one side, preferably on a long side. Alternatively, the securing lug can also be attached to one or to two opposite short sides of the securing clip.
  • the safety clip can also be provided several times. The securing clip is attached to the receiving flange in an axially immovable but rotatable manner.
  • an insertion bevel is formed on the securing nose.
  • a simplified assembly of the protective hood on the receiving flange can be achieved by the insertion bevel, since this ensures that the securing lug can deflect radially inward when the protective hood is mounted on the receiving flange.
  • the lead-in bevel is designed in such a way that the securing clip of the securing device is perpendicular to the protective hood when the protective hood is being installed Mounting direction is adjusted radially. This ensures that the protective cover can be easily installed.
  • the lead-in bevel is only formed on one side, which means that when the protective cover is removed from the receiving flange, the limitation of the shape formed on the protective cover prevents the radial adjustment of the safety clip, the safety catch of which engages in the shape.
  • the securing clip is mounted movably in the circumferential direction on an annular groove formed on the receiving flange of the bearing plate.
  • special holding structures such as knobs, for example, have proven to be favorable on the securing clip, which in a particularly preferred embodiment are triangular.
  • the securing device is designed as a securing lug, it has proven to be advantageous if the securing lug, which is formed on the protective hood, provides a spring effect. As a result, the securing tab when mounting the protective hood on the Locating flange elastically deformed. When the protective hood is then mounted on the receiving flange, the pretensioned securing tab is moved back into the annular groove that is formed on the receiving flange and thus secures the protective hood on the receiving flange.
  • the securing tab can be moved mechanically into a securing position.
  • an auxiliary tool for example an embossing die, can be used with which the securing tab can be pressed into the annular groove after the protective hood has been installed on the receiving flange.
  • the receiving flange can be designed without coding.

  • the securing pins 20 protrude beyond the pin receptacles 22 and into the axial groove 15 and block the radial projections 16 in such a way that the protective hood 13 cannot be removed from the receiving flange 12 even in the assembly position.
  • a part of the axial grooves 15 of the coding 14 is blocked by the locking pins 20, so that the protective hood 13 cannot be removed. Rotation of the protective hood 13 guided in the annular groove 18 from the assembly position into the working position is nevertheless possible without any changes.

  • the locking cap 23 is secured to the bearing plate 10 by the locking pin 20.
  • the locking cap 23 prevents the locking pin 20 from penetrating the annular groove 18 through the pin receptacle 22 by the user, since the locking cap 23 - namely the projection 24 - represents a stop 26 that prevents manipulation by the user effectively prevents and thus prevents the user from being able to remove the protective hood 13.
