In order to solve the problems, the following technical scheme is provided:
the utility model discloses a characteristics of water pump cavity border device are including the support, have pivot and connecting axle on the support, and the axis of pivot and the axis of connecting axle are on same straight line, have between pivot and support to be used for driving pivot pivoted first drive arrangement, have between connecting axle and support to be used for driving the second drive arrangement of connecting axle along its axis motion. One end of the rotating shaft close to the connecting shaft is concentrically connected with a chuck for fixing a water pump cavity. There is the door-shaped frame on the connecting axle, the opening of door-shaped frame is towards the chuck, there is the first round pin axle that stretches out perpendicularly outwards on the outer terminal surface on a door-shaped frame perpendicular limit, it is used for carrying out the first bearing of border to the interior circle of water pump cavity to be fixed with one heart on the first round pin axle, there is logical groove between the front and the back on another perpendicular limit of door-shaped frame, the one end that leads to the groove is located the outer terminal surface on this perpendicular limit of door-shaped frame, make this logical groove be uncovered form, there is the second round pin axle between two groove walls that lead to the groove, it is used for carrying out the second bearing of border to the terminal surface of water pump cavity to be fixed with one heart on the second round pin axle, one side of second bearing stretches out outside from the opening end that leads to the groove.
The chuck is a three-grab chuck.
By adopting the scheme, the method has the following advantages:
because the utility model discloses a there are pivot and connecting axle on water pump cavity border device's the support, there is first drive arrangement between pivot and support, there is second drive arrangement between connecting axle and support, it has the chuck to serve near the pivot of connecting axle, there is door-shaped frame on the connecting axle, the opening of door-shaped frame is towards the chuck, there is the first round pin axle that outwards stretches out perpendicularly on the outer terminal surface on door-shaped frame one perpendicular limit, there is first bearing on the first round pin axle, there is logical groove between the front and the back on another perpendicular limit of door-shaped frame, there is the second round pin axle between two groove walls that lead to the groove, there is the second bearing on the second round pin axle, one side of second bearing stretches out outside from the opening end that leads to the groove. When the water pump chuck is used, a water pump cavity to be processed is placed in the chuck, and the chuck is adjusted to clamp and fix the water pump cavity; then, starting a second driving mechanism to drive the connecting shaft and the door-shaped frame to move towards one side close to the chuck until the first bearing is abutted against the inner circle of the water pump cavity, and the second bearing is abutted against the end part of the water pump cavity; and finally, starting the first driving device to drive the chuck and the water pump cavity to rotate, wherein in the rotating process of the water pump cavity, the first bearing performs edge rolling processing on the inner circle of the water pump cavity, and the second bearing performs edge rolling processing on the end part of the water pump cavity. The device has the advantages of simple structure, high production efficiency and low processing cost. In addition, the edge rolling is carried out in a bearing extrusion mode, and materials do not need to be removed, so that the strength of the water pump cavity is ensured, and the service life of the water pump cavity is greatly prolonged.
