Definitions
- the invention relates to a machine for the finishing of workpieces, in particular for polishing, workpieces with an irregularly shaped surface, with a drum with magnetic devices in which the workpieces are processed by a ferromagnetic abrasive, the drum having a work area in the form of a Has annular body, which is surrounded by a bottom and cylindrical walls attached to the bottom, and with a device for holding and moving the workpiece.
- the workpiece is moved in a circular air gap of a fixed electromagnet along the air gap, being rotated about its own axis and at the same time axially oscillated by a complicated mechanical device to a to achieve as uniform polishing of the workpiece as possible.
- a disadvantage of this known machine is that when polishing workpieces with an irregular profile, all edges are undesirably rounded.
- the invention is therefore based on the object to design the machine of the type mentioned in such a way that all surfaces can be machined evenly in the case of workpieces with an irregular profile.
- the drum is rotatable, that the working area of the drum is closed at the top by a magnet that is immovable relative to the drum, that there is an electromagnetic coil and a disc in the center of the working area, which have a rigid axis on the Magnets are attached that the cylindrical walls of the work area are made of non-ferromagnetic material and that the bottom, the axis and the disc are made of ferromagnetic material.
- the bottom of the drum is advantageously mounted with a flange on the rigid axle.
- the workpieces are preferably fastened to spindles in workstations, vertically movable by pneumatic cylinders and rotatable by electric motors and reduction gears.
- the upper magnet of the drum together with the work stations is expediently rotated step by step by means of a disc with cam and dividing wheel, the work stations being in the lower position and only being raised by the pneumatic cylinder in the position corresponding to the first work station.
- the machine for finishing workpieces with an irregular profile can have, for example, six work stations which are arranged above the working area of the drum, which has a lower, rapidly rotating magnetic pole.
- Each work station is equipped with an electric motor, reduction gear and a spindle to which a chuck is attached for clamping the workpiece.
- the discreet rotation of all workstations, together with the upper magnetic core, is carried out by a separate electric motor with reduction gear and chain tooth gears.
- a central contact collector feeds the work stations. In the first working position, the work station is lifted by a pneumatic cylinder, whereby the finished workpieces can be removed and unprocessed ones can be used. In all other positions, the workstations are lowered into corresponding openings in the upper magnetic core.
- the advantages of the invention are that the quality of the machined workpieces is improved without changing their geometric shape, the machining of all surfaces taking place simultaneously.
- the machine according to the invention for the finishing of workpieces with an irregular profile consists of a drum 1, which is driven by an electric motor 3 via a belt drive 2.
- the drum 1 is mounted in a housing 4 and has a working area 5 in the form of an annular body which is surrounded by a base 6 and cylindrical walls 7 and is closed at the top by an immovable magnet 8.
- the walls 7 are attached to the floor 6.
- the bottom 6, the rigid axis 11 and the disk 10 are made of ferromagnetic material, while the cylindrical walls 7 of the toroidal working area 5 are made of non-ferromagnetic material.
- the bottom 6 of the drum 1 is mounted with a flange 21 on the rigid axis 11.
- the machine can be equipped with several drums 1. These drums 1 are arranged in a circle. In the center of this circle there is a device for feeding and removing the workpieces, for example a manipulator with grippers 12.
- the grippers 12 of the manipulator can move in the vertical direction and rotate about their axes.
- Pliers 17 for gripping the workpieces are mounted on the plates 13.
- the workpieces are fed to the tongs 17 by means of an oriented feed device 18, and after the machining is finished they are removed from the tongs 17 by a conveyor-unloading device 19 with a control block 20.
- the machine according to the invention works as follows:
- the work area 5 is filled with a ferromagnetic mixture of abrasives. Then workpieces are fed to the pliers device 17 by the device 18 for the oriented feed.
- the manipulator When the manipulator is actuated, its grippers move upwards, after which they are pivoted by the forceps device 17 over the working area 5 of the centrifugal drum 1.
- the drum 1 begins to rotate and the grippers 12 of the manipulator move down together with the pliers devices 17 until the workpieces are immersed in the ferromagnetic abrasive mixture which fills the working area 5.
- the electromagnetic coil 9 is switched on, which generates a magnetic field with appropriate orientation.
- the machined workpieces are rotated, polishing their surfaces.
- the grippers 12 of the manipulator move upwards again and rotate.
- the workpieces thereby reach the work area of another, analog centrifugal drum 1, which rotates in the opposite direction.
- the workpieces are above the starting position. They are removed from the pliers devices 17 by the removal device 19 with the control block 20.
- the machine shown in FIGS. 3 and 4 has six workstations 21 to 26, which represent identical independent units.
- Each of the work stations 21 to 26 has a separate electric motor 38 which drives a work spindle 32 via a reduction gear, to which a mandrel 33 is fastened with a workpiece.
- the individual workstations 21 to 26 each have two ball guides 36, which can move vertically along guides 35. This movement is carried out by pneumatic cylinders 40.
- Each mandrel 33 with workpiece passes through a closure 34 which is inserted in a corresponding opening in the upper magnet 8 (FIG. 2) of the centrifugal drum 27 and closes off the working area 31 from above.
- the magnetic field in the working area 31 is generated by an electromagnetic coil 28.
- the magnetic centrifugal drum 27 is driven by an electric motor 30 via a pulley 29.
- the six work stations 21 to 26, together with the ball guides 36 and the guides 35, are arranged between two disks, the pneumatic cylinders 40 being arranged above the upper disk 39 for vertical movement.
- An electric motor 43 drives a chain tooth transmission 45, a reduction gear 46 and a second chain transmission 47, 48 and a disk with cams 42 via a clutch 44.
- the cam 42 can penetrate radial incisions of the dividing wheel 41 (Maltese cross mechanism) and gradually drive the entire system.
- the compressed air for the pneumatic cylinders 40 is supplied through an air line 51 and a connection 50 and distributed by a pneumatic distributor 37.
- All electric motors of workstations 21 to 26 are supplied with power via a contact collector 49.
