Screwing station

Abstract

The invention relates to a screwing station ( 2 ) in which transmission housings ( 4 ) are screwed together. Said screwing station is provided with a connecting plate ( 8 ) that is detachably linked with the transmission housing ( 4 ). A first guide ( 10 ) is disposed on the connecting plate ( 8 ), along which guide a second guide ( 12 ) can be displaced relative to the connecting plate on a first axis ( 14 ). On the second guide ( 12 ) a third guide ( 16 ) is disposed which can be displaced relative to the connecting plate ( 8 ) along a second axis ( 18 ) that is at a right angle to the first axis ( 14 ), thereby allowing a screw driver ( 20 ) a displacement relative to the connecting plate ( 8 ) along a third axis ( 22 ) that is at a right angle to the second axis ( 18 ).

         3 . Screw pickup ( 2 ) according to  claim 1 , characterized in that the screw-driving machine ( 20 ) can be moved relative to the connection plate ( 8 ) along the third axis ( 22 ) on the third track ( 16 ).  
     
     
         4 . Screw pickup ( 2 ) according to any of  claims 1  to  3 , characterized in that the tracks ( 10 ,  12 ,  16 ) are each driven by an electrical motor.  
     
     
         5 . Screw pickup ( 2 ) according to  claim 4 , characterized in that the electrical motors of the tracks ( 10 ,  12 ,  16 ) and of the screw-driving machine ( 20 ) are actuated by a control device ( 26 ), which is integrated into the screw pickup ( 2 ).  
     
     
         6 . Screw pickup ( 2 ) according to  claim 5 , characterized in that the control device ( 26 ) can be programmed in such a way that, in predetermined positions, the screw connections are actuated by the screw-driving machine ( 20 ), and are tightened to a predetermined degree of torque.  
     
     
         7 . Screw pickup ( 2 ) according to any of  claims 1  to  6 , characterized in that the tracks ( 10 ,  12 ,  16 ) are located within a protective device ( 24 ) and the screw-driving machine ( 20 ) is simply moved within the protective device ( 24 ).  
     
     
         8 . Screw pickup ( 2 ) according to  claim 7 , characterized in that access to the internal workings of the protective device ( 24 ) is possible.  
     
     
         9 . Screw pickup ( 2 ) according to any of  claims 1  to  8 , characterized in that the screw-driving machine ( 20 ) maintains a constant axis of rotation during the actuation of the various screw connections of the gear box ( 4 ).  
     
     
         10 . Screw pickup ( 2 ) according to any of  claims 1  to  9 , characterized in that the screw-driving machine ( 20 ) is an electrically operated screw-driving machine.  
     
     
         11 . Screw pickup ( 2 ) according to any of  claims 1  to  9 , characterized in that the screw-driving machine ( 20 ) is a pneumatically operated screw-driving machine.  
     
     
         12 . Screw pickup ( 2 ) according to  claim 11 , characterized in that the electric motors of the tracks ( 10 ,  12 ,  16 ) and the air supply of the pneumatically operated screw-driving machine ( 20 ) are actuated by the control device ( 26 ) which is integrated within the screw pickup ( 2 ).  
     
     
         13 . Process for the assembly of gear boxes ( 4 ) characterized in that, in a screw pickup ( 2 ) which is detachably fastened to the gear box ( 4 ) by means of the connection plate ( 8 ), by means of a screw-driving machine ( 20 ) which can be moved in three directions, various positions of screw connections of the gear box ( 4 ), which have been programmed prior to assembly, are accessed and tightened to a predetermined torque.
