Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy wheel hub processing, in particular to an aluminum alloy wheel hub spinning machine. Background Art

[0002] The wheel hub is a cylindrical metal component whose inner profile supports the tire and whose center is mounted on the axle. Aluminum alloy wheel hub has high strength and is often used in large trucks.

[0003] When aluminum alloy wheels are produced, spinning equipment is used to perform spinning processing on them to form patterns on the surface of the aluminum alloy wheels. Currently, when processing aluminum alloy wheels, the aluminum alloy wheels are placed vertically in the spinning equipment and limited in the spinning equipment by a limiting mechanism. Since the weight of the aluminum alloy wheels themselves is not taken into consideration, the following deficiencies occur during processing: when the wheel is made of aluminum alloy, its own weight will be heavier, and when the aluminum alloy wheel is heavier, it is not convenient to limit it vertically in the spinning equipment, which not only increases the workload of the operator, but also makes the aluminum alloy wheel very prone to unstable center of gravity during processing. When the aluminum alloy wheel shakes in the spinning equipment, it is very easy to cause deformation on the surface of the wheel, which seriously affects the efficiency and level of aluminum alloy wheel processing.

[0023] A support plate 6 for supporting the wheel hub is fixedly installed on the sleeve 5. The sleeve 5 is connected to a limit plate 7 that movably contacts the center hole of the wheel hub through a connecting piece. A limit cover 15 for limiting the center hole of the wheel hub is detachably installed on the sleeve 5. After the aluminum alloy wheel hub is placed on the sleeve 5, the sleeve 5 can penetrate the center hole of the aluminum alloy wheel hub, so that the aluminum alloy wheel hub can be placed on the support plate 6. The inner wall of the center hole of the aluminum alloy wheel hub is contacted and limited by four limit plates 7, so that the stability of the aluminum alloy wheel hub during processing can be guaranteed;

[0024] The connecting member includes a guide rod 8 fixedly installed in the sleeve 5, and four circumferentially distributed guide plates 9 are fixedly installed on the guide rod 8, a connecting plate 10 is slidably sleeved in the guide plate 9, and a spring 11 is welded between the connecting plate 10 and the guide plate 9, and the guide plate 9 guides and limits the connecting plate 10 and the slide plate 12, so that the connecting plate 10 can smoothly pull the limit plate 7 when moving;

[0025] The guide rod 8 is vertically arranged, and the spring 11 is horizontally welded to the connecting plate 10 and extends to a side position inside the guide plate 9. The spring 11 realizes the reset function of the connecting plate 10. When the sliding sleeve 13 is in an unloaded state, the spring 11 can pull the connecting plate 10 and the limit plate 7 back to the initial position. The limit plate 7 is arranged on the connecting plate 10. The limit plate 7 and the connecting plate 10 extend to a side position outside the guide plate 9, and the limit plate 7 is an arc-shaped structure adapted to the center hole of the wheel hub. By setting the limit plate 7 as an arc-shaped structure adapted to the center hole of the wheel hub, the contact degree between the limit plate 7 and the center hole of the wheel hub can be increased.

[0026] A slide plate 12 is fixedly installed on the connecting plate 10, a slide sleeve 13 is provided on the guide rod 8, and a connecting rod 14 is connected between the slide sleeve 13 and the slide plate 12, and two ends of the connecting rod 14 are respectively connected to the slide sleeve 13 and the slide plate 12 pin shaft, and the guide plate 9 is horizontally arranged at a position below the slide sleeve 13, and a locking bolt detachably connected to the sleeve 5 is threadedly connected to the limit cover 15, and a ring sleeve 16 for applying pressure to the slide sleeve 13 is fixedly installed on the limit cover 15, and the ring sleeve 16 is driven by the limit cover 15 to apply pressure to the slide sleeve 13, so that the slide sleeve 13 can apply pressure to the connecting rod 14 after moving downward, and then the four limit plates 7 can limit the inner wall of the center hole of the wheel hub, so that the aluminum alloy wheel hub will not shake due to its own weight during processing, thereby effectively improving the efficiency of aluminum alloy wheel hub processing.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] Place the wheel hub in the support 4 so that the sleeve 5 in the support 4 can pass through the center hole of the wheel hub, so that the wheel hub can be placed on the support plate 6;

[0029] The limit cover 15 is manually pressed, so that the limit cover 15 drives the ring sleeve 16 to press the sliding sleeve 13 when it moves downward, and the sliding sleeve 13 pulls the connecting rod 14 to deflect when it moves downward. The connecting rod 14 presses the slide plate 12 when it deflects, so that the slide plate 12 drives the connecting plate 10 to slide in the guide plate 9, and the spring 11 is stressed, so that the connecting plate 10 drives the limit plate 7 to extend outside the sleeve 5 and press the position of the center hole of the wheel hub when it moves;

[0030] At the same time, the limiting cover 15 can press and limit the center hole of the hub from the top, and the limiting cover 15 and the sleeve 5 are connected by a locking bolt;

[0031] The output end of the motor 2 drives the rotating shaft 3 to rotate, so that the rotating shaft 3 drives the support 4 and the wheel hub to rotate, and the operator can use tools to perform spinning processing on the wheel hub;

[0032] After the processing is completed, the locking bolt is disassembled, and the limit cover 15 is disassembled, and the processed wheel hub can be taken down, and the metal debris in the support 4 can be cleaned.
