Definitions

  • the invention relates to a hand grinder with a grinder housing, in which a grinding spindle is rotatably mounted, with a protective hood for a tool, which is rotatably mounted on a clamping neck by means of a holding part and can be fixed thereon.
  • a hand grinder is known in which the protective hood is rotatably mounted on the clamping neck and is held with axial play, whereby to compensate for this play a resilient element biased in the axial direction is used, which against a fastening ring of the protective hood a shoulder surface on the neck presses. As a result, the protective hood is secured against rotation by friction.
  • the disadvantage of this device is the fact that the protective hood can be adjusted unintentionally, especially when you think that such grinding machines are often used in confusing places, the user must be sure that the protective hood is in the correct position and also remains in this.
  • a hand grinder of the type mentioned in which the protective cover is releasably attached to the spindle neck of the gear housing by means of a clamp and a fastening screw.
  • a securing element is provided in the region of the end face of the spindle neck, which protrudes beyond the outside diameter of the spindle neck and the inside diameter of the clamping clamp.
  • This securing element can be designed as a flat disk and fastened with a screw on the end face of the spindle neck.
  • the securing element can be designed as a spring-loaded lever and can be pivotably mounted on the spindle neck.
  • a stationary machine tool in which a protective hood for a rotating tool is provided, which can be fixed to a rear plate of the machine housing via a ring rigidly connected thereto.
  • Various circumferential recesses of the ring are used for the connection, through which bolts can be inserted into the rear plate.
  • a spring-loaded pin is provided, which can be snapped into one of the recesses on the circumference of the ring.
  • the invention has for its object to improve a grinding machine of the generic type such that an unintentional adjustment of the protective hood, for example by lateral pressure, is no longer possible.
  • the fixing part is held in a rotationally fixed manner in the area of the clamping neck, that the fixing part or the holding part has at least one and the other part has several locking elements which can be locked together and are loaded by a spring member, which are detachable from each other against the spring force, that the fixing part and the holding part can be tilted relative to one another, and that the fixing part has a lever for tilting, which extends between the protective hood and the grinding machine housing.
  • the locking elements which can be locked together, provide a positive and non-rotatable connection between the holding part and the grinding machine housing, so that the protective hood can no longer twist and that this connection can only be released against the spring force.
  • the fact that the locking part and the holding part can be tilted relative to one another results in a structurally particularly simple solution. Since a lever is provided for actuating the locking part, which extends between the protective hood and the grinding machine housing, simple and ergonomically advantageous actuation is ensured.
  • the locking elements are locking recesses provided on one part and locking bodies provided on the other part, in which case the locking bodies can engage in the locking recesses.
  • the latching depressions are bores, while in the simplest case the latching body is a pin that engages in these bores.
  • a very easy to implement implementation of the invention provides that a locking body and several locking recesses are provided, the single locking body is then arranged on the holding or locking part and the locking recesses on the other part.
  • the holding part is designed as a ring surrounding the clamping neck, which is preferably integrally formed on the protective hood.
  • the locking part can be a ring enclosing the clamping neck.
  • the locking part With regard to a tiltable mounting of the locking part in relation to the clamping neck, it would be conceivable to mount the locking part on it with play and to place it against a shoulder, for example by means of a spring. But it is also conceivable that the locking part is made of resilient material and thus with one end firmly on the instep is arranged neck or on the grinder housing and creates by its own spring action the possibility that the locking part is so deformable that the locking body can be disengaged from the locking recesses.
  • the spring member is an annular element enclosing the clamping neck, with which the respective tiltable part is placed against a shoulder.
  • FIG. 1 An angle grinder shown in FIG. 1, designated as a whole by 1, shows a motor housing 2 and a gear housing 3.
  • a grinding spindle 4 protrudes from the gear housing 3 and carries a clamping flange 5 at its end.
  • a grinding wheel 6 is placed on this clamping flange 5 and clamped against the clamping flange 5 by a counter flange 7 of a screw that can be screwed into the grinding spindle 4.
  • the grinding wheel 6 is partially covered by a protective hood designated as a whole, which is rotatably mounted on a clamping neck 9 surrounding the grinding spindle 4 between the counter flange 5 and the gear housing 3 and mounted on the gear housing 3.
  • the clamping neck 9 is subdivided into a total of three sections 10 to 12, which are coaxial with the grinding spindle 4 and with a successively smaller outside diameter starting from the gear housing. Between these circular-cylindrical sections 10 to 12, annular contact surfaces 13 and 14 are thereby formed in planes perpendicular to the axis of rotation of the grinding spindle 4.
  • the first circular cylindrical section lying adjacent to the gear housing 3 is surrounded by a spring element 15, which is supported on the one hand on a surface 16 formed by the transmission housing 3 and perpendicular to the axis of rotation of the grinding spindle 4 and on the other hand on a ring also surrounding the first circular cylindrical section 10 17 of a locking element designated as a whole by 18. which also has a lever arm 19 molded onto the ring 17, which extends in a space between the protective hood 8 and the motor housing 2.
  • the ring 17 is pressed by the spring element 15 against an intermediate ring 20 seated on the second circular-cylindrical section 11, which in turn bears against the contact surface 13 between the circular-cylindrical section 10 and the smaller-diameter circular-cylindrical section 11.
  • the intermediate ring 20 is in turn held by a fixing ring 21, which sits on the third circular cylindrical section 12 and bears against the contact surface 14.
  • This fixing ring 21 is held by a snap ring 22, which engages in a circumferential groove 23, machined into the third circular-cylindrical section 12.
  • the intermediate ring 20 is provided on its side facing the fixing ring 21 with a radially outward opening and an annular recess 24 open to the fixing ring 21, in which an annular holding part 25 of the protective hood 8 can be rotated coaxially to the grinding spindle 4, but in is axially fixed.
  • This holding part 25 has holes 26 arranged at the same angular distance on a circular arc segment. One of these bores 26 engages with a pin 27 arranged on the fixing part 18 in the region of the transition between the ring 17 and the lever arm 19, which extends from the fixing part 18 through a recess 28 in the intermediate ring 20 to the holding part 25.
  • the ring 17 is held on the first circular-cylindrical section 10 with play so that it can be displaced in the direction of the gear housing 3 in the axial direction of the grinding spindle 4 against the action of the spring element 15, which is, for example, a wave spring or a rubber ring .
  • the spring element 15 which is, for example, a wave spring or a rubber ring .
  • the protective hood 8 which is rotatably mounted with the holding part 25 in the intermediate ring 20, can be freely rotated around the clamping neck 9.
  • the pin 27 is moved again in the direction of the holding part 25 by the spring element 15, so that he now comes into engagement with the opposite bore 26 and the holding part 25 with the protective cover 8 rotatably fixed on the collar 9. This is done in that the pin 27 is non-rotatably fixed on the clamping neck 9 through the recess 28.
  • the walls of the bores 26 are shaped so that the pin 27 cannot jump out of the bores 26 even when there is strong lateral pressure on the protective hood 8. Furthermore, in order to be able to lock the protective hood 8 in all conceivable rotational positions, it is provided that the bores 26 are provided on the holding part 25 in a large circumferential area, all of which are centered on a circular path segment concentric with the clamping neck 9.
  • FIG. 2 shows a protective hood 8 which is likewise rotatable about the clamping neck 9 by the intermediate ring 20 and the fixing ring 21 with their holding part 25.
  • the holding part 25 is not provided with bores 26 arranged coaxially to the grinding spindle 4, but with recesses 30 which extend in the radial direction from an outside of the holding part 25 in the direction of the clamping neck 9, which are preferably in the peripheral region of the holding part 25 are provided, which does not merge into the protective hood 8.
  • a pin 31 aligned in the radial direction of the clamping neck 9 engages in these recesses 30 and is held on a lever 32 made of resilient material which extends parallel to an axial direction of the clamping neck 9 on an outer side thereof so that the pin 31 protrudes from this lever 32 in the direction of the holding part 25.
  • the lever 32 is preferably made of resilient material and held on the gear housing 3, for example by means of a screw 33.
  • the pin 31 can be disengaged from the recess 30, as a result of which the protective hood 8 can be rotated on the clamping neck.
  • the lever 32 is preferably provided with a tongue 34 which extends beyond the pin 31 and forms a front end of the same and which permits simple actuation of the lever 32.
  • the lever 32 thus forms the locking part and replaces the lever 18 of the first exemplary embodiment.
  • the holding part is of identical design to that in the second exemplary embodiment and likewise has recesses 30 which extend in the radial direction towards the clamping neck 9 and are open to the outside.
  • a rocker arm 40 is provided, which is mounted rotatably about an axis 41, parallel to the axis of rotation of the grinding spindle 4, on the transmission housing 3.
  • a first lever arm 42 arranged on one side of the axis of rotation 41 bears against a spring 43 which is supported on its opposite side on the transmission housing 3 and thereby acts on the first lever arm 42 away from the transmission housing.
  • a second lever arm 44 which is opposite the first lever arm 42 with respect to the axis of rotation 41, is acted upon in the direction of the clamping flange 9, so that a pin 45 arranged at the front end of the locking part 25 of the holding part 25 is held in engagement with one of the recesses 30 becomes.
  • the lever arm 44 In order to arrange the pin 45 in engagement with the recesses 30, the lever arm 44 must be bent in the axial direction of the clamping neck 9.
  • the lever 40 is preferably provided at a rear end of the first lever arm 42 opposite the axis of rotation 41 with a pressure surface 47, which allows the same to be acted upon and thus the pin to be disengaged from the recesses 30.
