Description

TECHNICAL FIELD

[0001] The utility model belongs to hub processing technical field especially relates to a hub spoke shaping production line. BACKGROUND

[0002] In the hub production and processing process, the core component spoke of the hub is formed into a spoke blank after preliminary processing, and then the rim of the hub is processed into a shape by the production line. After the subsequent rim forming, the spoke is welded into the rim and forms the entire completed hub.

[0003] However, the size of the hub used with different vehicles is often the same, that is, one size of the hub can be used on different vehicles, but the difference is that the shape of the spoke suitable for different vehicles is different.

[0004] Therefore, the spoke needs to be shaped according to the spoke shape required by the customer in the last stage of the hub production process. The current shaping method is to put the hub into a numerical control vehicle, and then mill the spoke on the hub to a specific shape by a milling cutter in the numerical control lathe, and complete the entire hub production and processing process.

[0005] Currently, the hub is loaded onto the conveyor in the workshop, and the operator loads the hub at the discharge end of the conveyor. However, first of all, the discharge speed of the assembly line is very fast, so the traditional manual unloading and loading into the lathe obviously does not match the speed of the high-speed running assembly line, resulting in low production efficiency.

[0006] Secondly, due to the large weight of the hub itself, it is easy to cause the hub to be knocked during the handling and loading process, and the main material of the hub is aluminum alloy material, so the appearance of the hub is easily affected after being knocked, causing the hub to be damaged.

[0007] Therefore, in the face of the above technical defects existing in the actual production process, if an automatic production line with fast production speed, high production smoothness and low labor workload can be used, not only the production efficiency can be greatly improved, but also a series of defects caused by manual loading and unloading can be effectively solved, such as the problems caused by the above handling process.

[0045] Specifically, a plurality of mechanical arm mechanisms for grabbing the hub are arranged between the first belt conveyor 3 and the second belt conveyor 4; a lathe is arranged at the front side of the first belt conveyor 3, and the second belt conveyor 4 is arranged at the rear side of the first belt conveyor 3; the second belt conveyor 4 is arranged apart from the lathe through the first belt conveyor 3.

[0046] During operation, the hub blank C is conveyed by the second belt conveyor 4, then is grabbed by the mechanical arm mechanism, and is then fed into the lathe, and then, when the spoke on the hub blank C is processed by the lathe, the hub product is unloaded by the mechanical arm and is then conveyed by the second belt conveyor 4.

[0049] Embodiment 2

[0050] As shown in Figures 1-5 the second belt conveyor 4 is provided with a plurality of hub lifting mechanisms 41.

[0051] Specifically, when the hub blank C is fed to the feeding end of the second belt conveyor 4, the hub blank C is conveyed on the second belt conveyor 4, and when the hub blank C is conveyed to the position of the hub lifting mechanism 41, the hub lifting mechanism 41 clamps and lifts the hub blank C, and then the mechanical arm grabs the lifted hub blank C.

[0052] Specifically, the hub lifting mechanism 41 comprises hub pressing cylinders 411 respectively arranged at both sides of the second belt conveyor 4, and the piston rods of the hub pressing cylinders 411 are fixedly connected with pressing seats 412 pressing on the waist of the hub blank C.

[0053] Specifically, in order to achieve stable clamping of the wheel hub blank C, the aforementioned pressing seat 412 is provided with an arc-shaped opening for clamping the waist of the wheel hub blank C according to the shape of the wheel hub blank C. Under the action of the wheel hub pressing cylinders 411 on both sides, the pressing seat 412 is clamped on both sides of the waist of the wheel hub blank C and maintains stable clamping.

[0057] During operation, driven by the lifting cylinder 414, the hub pressing cylinder 411, the pressing seat 412, and the hub blank C held by the pressing seat 412 are raised to a certain height, and then the robotic arm mechanism grabs the hub blank C.

[0058] The above method enables the wheel hub blank C to be clamped, locked, and raised in a highly stable manner, facilitating its loading into the lathe in conjunction with the robotic arm mechanism.

[0059] Example 3

[0060] like Figures 1-5 As shown, this embodiment is based on the structure of embodiment 2. In order to maintain the correct posture of the wheel hub blank C during the feeding process, which is heavy and heavy, that is, to clamp and feed the wheel hub blank C in a stable and accurate manner, the above-mentioned robotic arm mechanism includes a spoke robotic arm body 251 (the spoke robotic arm body is a conventional robotic arm used for gripping materials in conventional industrial production disclosed in the prior art).

[0061] Specifically, a spoke gripping structure 252 is installed on the spoke robotic arm body 251; the spoke gripping structure 252 includes a gripping mounting frame 2521 installed on the spoke robotic arm body 251, a gripping cylinder 2522 is installed on the gripping mounting frame 2521, and the gripping cylinder 2522 has a plurality of cooperating cylinder piston claws 2523, and the spokes B on the hub grip the material between the cylinder piston claws 2523.

[0062] Specifically, the grabbing cylinder 2522 is a three-jaw grabbing cylinder 2522 disclosed in the prior art, and three circumferentially distributed cylinder piston jaws 2523 are mounted on the cylinder. In order to increase the stability of the spoke B, the cylinder piston jaws 2523 are respectively fixedly connected with the pressure heads 25231 which are pressed on the spoke B.

[0063] During operation, under the driving of the spoke mechanical arm body 251, the spoke grabbing structure 252, the grabbing cylinder 2522 realizes the grabbing of the spoke B through the cooperation of the cylinder piston jaws 2523, and then the hub blank C is fully grabbed.

[0064] Since the spoke B is located at the center of the hub blank C and is small in size and easy to grab, the center of the hub blank C is grabbed, so that the stability of grabbing is high, and the balance of the hub blank C can be maintained after grabbing, the hub blank C is grabbed in a horizontal posture, and precise feeding to the lathe is facilitated.

[0065] The above-mentioned method greatly improves the stability of the hub blank C grabbing, and the mechanical arm is used for grabbing, which is not only efficient, but also can maintain the correct posture of the hub blank C during the grabbing process, thereby greatly improving the production efficiency and the safety of the grabbing and feeding.
