The present application relates to the technical field of burr removal after machining of wheels, specifically to a device for removing burrs from a riser of an aluminum alloy wheel.
The machining accuracy and machining quality of a wheel riser directly affect the installation of a buckle cap. After the wheel is machined, the edge of the riser is synthesized by casting and machined surfaces, so a circle of burrs remains. Currently, the burrs here are removed manually, the effect is not ideal, the front casting deformation of the riser increases the difficulty of removal, the deep or shallow groove and the large or small force will cause the burrs at the edge of the riser not to be removed smoothly, the customer will complain poor product consistency, and when the burrs are removed manually, the burrs may be missing or remain, and results in the unqualified appearance after coating and the corrosion caused by the incomplete coverage of a paint film. Based on the current situation, this application provides a device for automatically removing burrs from a wheel riser.
The object of the present application is to provide a device for automatically removing burrs from the edge of a wheel riser, which solves the problem of inconsistency of the riser after burr removal of a wheel, improves the effect of removing burrs from the edge of the riser, improves the efficiency of removing burrs and reduces the risk of riser corrosion. The device is simple, flexible and efficient, and may meet automatic continuous operation.
In order to achieve the above object, the technical solution of the present application is: a device for automatically removing burrs from a wheel riser is composed of a frame, a clamping gear rack structure, a support plate, a servo motor, lower guide rails, a left sliding plate, a clamping cylinder, shafts, clamping wheels, a left burr tool, ranging sensors, a feed gear rack structure, a left sliding block, a movable support plate, guide pillars, a feed cylinder, a right sliding block, upper guide rails, a cylinder support plate, a distance adjusting cylinder, a right burr tool and a right sliding plate.

When the clamping cylinder drives the left sliding plate to move, the right sliding plate moves synchronously with the left sliding plate under the action of the clamping gear rack structure to control the clamping wheels to center and clamp a wheel. The servo motor controls the rotation of the clamping wheels, so that the wheel may rotate while being clamped.
Two guide pillars are bilaterally symmetrically mounted at upper part of the frame, the feed cylinder is mounted in upper center of the frame, output end of the feed cylinder is connected to the movable support plate, the upper guide rails are mounted on the movable support plate, the left sliding block is connected with the right sliding block by the feed gear rack structure, the left burr tool is fixed on the left sliding block, and the right burr tool is fixed on the right sliding block, one of the ranging sensors is mounted on the left burr tool and another ranging sensor is mounted on the right burr tool, the cylinder support plate is fixed on the movable support plate, the distance adjusting cylinder is mounted on the cylinder support plate, and output end of the distance adjusting cylinder is connected to the right sliding block. When the distance adjusting cylinder drives the right sliding block to move, the left sliding block and the right sliding block move synchronously under the action of the feed gear rack structure, so that the left burr tool and the right burr tool move synchronously to adjust the distance between them according to the diameter of a cap slot. Under the guidance of the guide pillars, the feed cylinder controls the movable support plate to move up and down so as to realize feeding and resetting of the left burr tool and the right burr tool. The two ranging sensors respectively measure the distance from the left burr tool to the burrs of the riser and the distance from the right burr tool to the burrs of the riser, an average value is taken and then a signal is fed back to the feed cylinder to determine the exact descending distances of the left burr tool and the right burr tool, and the burrs are accurately removed by cooperation of the rotating wheel, the left burr tool and the right burr tool linearly fed.
