Definitions

  • the invention relates to a device for vibratory grinding of a workpiece, in particular a vehicle wheel, with the features of the preamble of claim 1.
  • a device for vibratory grinding of a vehicle wheel is known from the utility model DE 20 2005 021 013 U1 .
  • the known device has a pot-shaped working container which can be driven to vibrate with vibration exciters.
  • On a floor of the work container there are spacers on which a sliding-grinding vehicle degree is placed manually and clamped against the spacer with a clamping nut.
  • the clamping nut is screwed onto a shaft which is fastened coaxially in the work container on the bottom of the work container and passes through a center hole of a wheel hub of the vehicle wheel.
  • the object of the invention is to propose a device for vibratory grinding of a workpiece, in particular a vehicle wheel, which simplifies the introduction of the workpiece into and removal from the working container.
  • the device according to the invention for vibratory grinding of a workpiece has a working container to hold the workpiece or several workpieces and grinding tools. Vibratory grinding can be carried out dry or with a liquid in addition to the grinding tools in the work container.
  • the working container has an opening of sufficient size for the workpiece to pass through, through which the grinding bodies and, if necessary, a liquid can also be filled into the working container and removed from it.
  • the working container can have a drain opening for draining off a liquid.
  • the grinding tools and / or, if available, a liquid do not have to be changed every time the workpiece is changed, but can remain in the working container for the next workpiece. When it is placed in the work container, the workpiece is immersed in the grinding wheel and, if necessary, the liquid, if they are already in the work container.
  • the device has a fastening device in the work container which, according to the invention, is movable such that the workpiece fastened to it can be moved from a grinding position into a fastening and removal position and vice versa.
  • the workpiece In the grinding position, the workpiece is preferably completely in the working container, in particular it is at a distance from the opening so that it can be completely immersed in the grinding body and possibly the liquid when the opening of the working container is at the top.
  • the fastening device preferably holds the workpiece in the grinding position in such a way that it does not touch either a wall or a floor of the work container, but rather can be completely surrounded by grinding bodies.
  • the workpiece fastened to it is preferably completely outside of the working container, so that it can easily be gripped at any point manually or by machine, for example with a robot, in order to remove the workpiece from the fastening device or to attach to her. It is also conceivable that the fastening device holds the workpiece in the fastening and removal position in the opening of the working container, see above that the workpiece is partly outside and partly inside the working container and can be easily gripped in one or more places outside the working container.
  • One advantage of the invention is the simple attachment and removal of the workpiece outside of the working container to and from the fastening device. Another advantage is that the fastening device dips the workpiece fastened to it into the grinding body and, if present, a liquid in the working container. For this reason, no grinding bodies need to be removed from the work container in order to fasten and loosen the workpiece, or at least no fastening point has to be exposed in the work container.
  • One embodiment of the invention provides a lifting device for moving the workpiece out of the working container in the direction of the opening of the working container and preferably out of the working container and vice versa.
  • a lifting device can, for example, have articulated levers or scissor levers that cross each other in an articulated manner.
  • One embodiment of the invention provides a linear actuator with, for example, a linear motor, a screw drive or a cylinder that can be driven by an electric motor and, because of a long stroke in relation to an overall length, in particular a telescopic cylinder as part of the fastening device for moving the workpiece out of the working container in the direction of the opening of the Working container and preferably out of the working container and vice versa.
  • a telescopic cylinder has several cylinders which can be pushed into one another and pulled apart.
  • the cylinder or telescopic cylinder can be viewed as a linear actuator.
  • the cylinder or telescopic cylinder can be actuated pneumatically, ie with compressed air or generally a pressurized gas.
  • one embodiment of the invention provides a cylinder or telescopic cylinder that can be operated hydraulically, ie with a pressurized fluid, in particular with a hydraulic oil or water.
  • One embodiment of the invention provides a pot-shaped work container and a fastening device which can be moved by at least one depth of the work container.
  • the depth of the working container is a distance of the opening from a floor or a wall or the like of the working container opposite the opening. This stroke height or distance by which the fastening device can move the workpiece enables the workpiece to be moved back and forth between the grinding position of the workpiece, which is completely recessed in the work container, and the fastening and removal position completely outside the work container.
  • the fastening device has a clamping device for the vehicle wheel or a support for a wheel hub of the vehicle wheel.
  • the clamping device can clamp a rim on a circumferential rim edge with clamping jaws, as is known from wheel balancing machines and tire mounting machines. Other clamping devices are also possible.
  • the support for the wheel hub can be designed like an axle hub of a motor vehicle to which the wheel hub of the vehicle wheel can be fastened.
  • the support according to the invention preferably has a quick release fastener or a quick release device for fastening the wheel hub to the support. Other supports are also possible.
  • One embodiment of the invention provides that the working container is arranged to vibrate, for example with springs, straps or the like, on a frame, for example, and that the device has one or more vibration generators with which the working container can be driven to vibrate. Due to the vibrations of the working container with the workpiece fastened in it, relative movements are generated between the workpiece and the grinding bodies which process the surfaces of the workpiece.
  • the vibration generator can, for example, generate sinusoidal, square, triangular, sawtooth vibrations and any vibrations per se.
  • the device 1 according to the invention shown in the drawing is used for vibratory grinding of a workpiece, in particular a vehicle wheel and, for example, a light metal wheel 2 of a motor vehicle (not shown). It has a pot-shaped working container 3 with a circumferential wall 4, which is cylindrical in the exemplary embodiment, and a circular base 5.
  • the working container 3 is arranged upright, i. H. the bottom 5 is below and an opening 6 above.
  • the opening 6 of the working container 3 is sufficiently large to allow the light metal wheel 2, which forms the workpiece, to be introduced into and removed from the working container 3.
  • the working container 3 is arranged on springs 7 such that it can vibrate.
  • a vibration generator 8 is arranged on the working container 3, with which the working container 3 can be driven to vibrate.
  • the vibration generator 8 has two unbalanced masses 9, which are eccentric on both sides of an electric motor (not shown) on a motor shaft of the electric motor are arranged and can be driven to rotate with the electric motor.
  • Other vibration generators 8 are possible.
  • a telescopic cylinder 10 is arranged as a lifting device 11 in a fixed manner in the working container 3 perpendicular to the base 5. “Fixed” means that the lifting device 11 moves with the working container 3, the telescopic cylinder 10 swings with the working container 3.
  • the telescopic cylinder 10 is actuated pneumatically or hydraulically; hydraulic actuation is provided in particular for heavy workpieces. Pneumatic actuation is normally sufficient for vehicle wheels.
  • the telescopic cylinder 10 has a support 12, which is disk-shaped in the exemplary embodiment, for a wheel hub 13 of the light metal wheel 2 forming the workpiece.
  • a mandrel 14 protrudes axially from the center of the support 12 to the telescopic cylinder 10, on which a clamping piece 16 can be detachably arranged by means of a bayonet lock 15, with which the wheel hub 13 can be clamped against the support 12.
  • the support 12 with the mandrel 14, the bayonet fastener 15 and the clamping piece 16 form a fastening device 17 for fastening the light metal wheel 2 forming the workpiece.
  • the bayonet fastener 15 and the clamping piece 16 form a clamping device 19 or a quick release device for fastening the light metal wheel forming the workpiece 2 or its wheel hub 13 on or on the support 12.
  • the telescopic cylinder 10 forms the lifting device 11 with which the fastening device 17 and with it the light metal wheel 2 between a grinding position ( Figure 1 ) and an attachment and removal position ( Figure 2 ) can be moved back and forth.
  • the light metal wheel 2 In the grinding position, the light metal wheel 2 is completely in the work container 3, that is, an upper side of the light metal wheel 2 is located under an upper edge 20 of the work container 3 that surrounds the opening 6
  • Working container 3 that is, a bottom of the light metal wheel 2 is located above the edge 20 of the working container 3 surrounding the opening 6.
  • the light metal wheel 2 can easily be placed on the support 12 manually or mechanically, for example with a robot, and fastened and then loosened and removed again.
  • the telescopic cylinder 10 can also be understood as a linear actuator.
  • a lifting height of the telescopic cylinder 10 and thus a path of the fastening device 17 is at least as long as the working container 3 is deep, the depth of the working container 3 being the distance between the base 5 and the opening 6.
  • the fastening device 17 is raised with the telescopic cylinder 10 forming the lifting device 11 into the fastening and removal position.
  • the light alloy wheel 2 is placed with its wheel hub 13 on the support 12 in such a way that the mandrel 14 passes through a central hole in the wheel hub 13.
  • the clamping piece 16 is then placed on and connected to the mandrel 14 by means of the bayonet catch 15, so that it clamps the wheel hub 13 against the support 12.
  • the light alloy wheel 2 is located above the working container 3 and thus outside the grinding bodies that are located in the working container 3.
  • the fastening device 17 is lowered together with the light metal wheel 2 into the grinding position in the work container 3, the light alloy wheel 2 being completely immersed in the grinding wheel, provided that so many grinding wheels are filled in the work container 3, that they cover the light alloy wheel 2 in the working container 3.
  • the working container 3 is driven by the vibration generator 8 to vibrate, which cause relative movements between the grinding bodies and the light metal wheel 2, as a result of which the grinding bodies process surfaces of the light metal wheel 2.
  • the fastening device 17 with the telescopic cylinder 10 forming the lifting device 11 is raised again into the fastening and removal position in which the light metal wheel 2 forming the workpiece is located above the working container 3.
  • the clamping piece 16 is now freely accessible again and can be released from the mandrel 14 and then the light metal wheel 2 can be removed from the support 12 manually or by machine.
