This application claims priority to Chinese Patent Application No. 201810272080.4, entitled DEVICE FOR REMOVING BURRS FROM ALUMIUM ALLOY WHEEL and filed on Mar. 29, 2018, which is incorporated herein by reference for all purposes.
The present invention relates to the field of aluminum alloy wheel manufacturing, in particular to a self-adaptive wheel burr removing device.
Many burrs are inevitably generated in the machining process of an automotive aluminum alloy hub. These burrs not only affect the attractiveness, but also affect the subsequent coating effect, especially with significant effect on the corrosion requirements. Due to the various shapes of the spoke back cavity, it is more difficult to remove the burrs at the spoke back cavity than in other positions. Since the angle between the brush and the back cavity is fixed and unadjustable, the conventional burr removing method cannot adapt to the shape of the spoke back cavity, and is low in burr removing precision and efficiency. Therefore, it is urgent to develop a self-adaptive wheel burr removing device with simple structure and good effect.
The aim of the present invention is to provide a self-adaptive wheel burr removing device in accordance with the deficiencies of the burr removing method mentioned above.
In one aspect of the present invention, provided is a device for removing burrs from an aluminum alloy wheel, the device comprises a workbench, columns, a brush, a spindle, a spindle box, a cross beam, a spindle motor, a controller, a clamp, a parallel robot, and a displacement sensor, the columns are fixedly connected to the workbench, and the cross beam is connected to the columns and the position of the cross beam can be adjusted along the columns; the spindle box is connected to the cross beam, and moves horizontally on the cross beam; the spindle, the spindle motor and the controller are mounted on the spindle box, and the brush is mounted at the end of the spindle; the brush is driven by the spindle motor and controlled by the controller; the displacement sensor is mounted in the brush; and the parallel robot is mounted at the bottom of the workbench; and the hub is fixed to the parallel robot by the clamp.
More than three displacement sensors are arranged in the brush and are ultrasonic displacement sensors.
The parallel robot uses a Stewart parallel platform.
The parallel robot is arranged such that the hub rotates 0-30 degrees relative to the horizontal plane.
The parallel robot drives the hub to rotate relative to the horizontal plane by means of a cylinder.
The cross beam is connected to the columns by bolts or guide rails.
The present invention adjusts the position and angle of the hub in real time through a displacement closed-loop control system to ensure that the brush is always attached to the hub back cavity, thereby achieving a good burr removing effect with the advantage of high automation, simple structure, high efficiency, saving manpower, etc., especially suitable for large-batch hub production sites. The displacement sensor can feed back position information of the surface of a hub approaching thereto in real time. The hub 9 is fixed to the parallel robot by the clamp. The parallel robot can implement precise six-dimensional adjustment, and can perform real-time posture adjustment according to the instruction of the controller to ensure that the brush is always attached to the spoke back cavity, thereby achieving a good burr removing effect.
The technical solution of the present invention is described as follows with reference to the drawings.
In which, 1 workbench, 2 column, 3 brush, 4 spindle, 5 spindle box, 6 cross beam, 7 spindle motor, 8 controller, 9 hub, 10 clamp, 11 parallel robot, 12 displacement sensor.
The present invention is further illustrated as follows in combination with the drawings and specific embodiments.
