[0033] Use Figure 1 , to illustrate a hub automatic assembly machine. This hub automatic assembly machine can be used for the installation of hub 102 components in the vehicle field. For example, the assembly of hub 102 and brake disc 101, and it can also be used for the assembly of other components. The following only elaborates on the assembly of hub 102 and brake disc 101.

[0034] First, use Figure 1-2 to describe the overall structure of the automatic hub assembly machine. The automatic hub assembly machine includes a first conveyor line 1, a steering mechanism 2, a second conveyor line 3, an assembly robot arm 4, and a PLC control system, where:

[0035] The PLC control system is electrically connected to the assembly robot arm 4, and the assembly robot arm 4 is also electrically connected to the electric control components on the first conveyor line 1, the steering mechanism 2, and the second conveyor line 3, and is used to coordinately control the automatic assembly production of the equipment.

[0036] The first conveyor line 1 is a transmission device with two conveyor chains. The two conveyor chains are arranged at intervals, and there is a transmission channel in the middle. The first conveyor line 1 is used to convey the first component to be assembled, and the first component can be a brake disc 101.

[0037] The steering mechanism 2 is arranged between the two conveyor chains of the first conveyor line 1 and is located at the output end of the first conveyor line 1, and is used to automatically steer the orientation of the brake disc 101 conveyed by the first conveyor line 1.

[0038] The steering mechanism 2 includes a first jacking cylinder 201, a bracket 202 installed at the output end of the first jacking cylinder 201, a second jacking cylinder 203 arranged on one side of the first jacking cylinder 201, and an automatic steering unit 204 installed at the output end of the second jacking cylinder 203.

[0039] The bracket 202 can be jacked up by the first jacking cylinder 201. When the brake disc 101 conveyed by the first conveyor line 1 reaches the top of the bracket 202, the bracket 202 can rise to support the brake disc 101 for blocking during the transmission of the brake disc 101. When it is sensed that the brake disc 101 is in place, the automatic steering unit 204 can be jacked up by the second jacking cylinder 203, and the automatic steering unit 204 rises for steering the orientation of the brake disc 101. At this time, the brake disc 101 with the orientation steered waits to be combined and installed with another component.

[0040] The second conveyor line 3 is a transmission device with two conveyor chains. The two conveyor chains are arranged at intervals, and there is a transmission channel in the middle, and is used to convey the second component to be assembled, and the second component can be a hub 102.

[0041] The number of the second conveyor lines 3 is two, and the two second conveyor lines 3 are arranged in parallel. Therefore, the two second conveyor lines 3 can transmit the hubs 102 simultaneously or alternately.

[0042] The second conveyor line 3 can be arranged on one side of the first conveyor line 1, and the output end of the second conveyor line 3 is located on one side of the automatic steering unit 204. Therefore, the hubs 102 transmitted on the two second conveyor lines 3 can be transmitted towards the orientation of the automatic steering unit 204, and further, the hubs 102 on the second conveyor line 3 can move towards the orientation of the brake disc 101 on the automatic steering unit 204.

[0043] The assembled robotic arm 4 is arranged on the second conveyor line 3. When the hub 102 conveyed on the second conveyor line 3 passes by the assembled robotic arm 4, the assembled robotic arm 4 can install the hub 102 onto the brake disc 101 after azimuth steering, thus completing the automatic installation of the hub 102 and the brake disc 101.

[0044] In this implementation scheme, the first conveyor line 1 can convey the brake disc 101 towards the direction of the steering mechanism 2. The first jacking cylinder 201 and the bracket 202 in the steering mechanism 2 can intercept and block the conveyed brake disc 101, while the second jacking cylinder 203 and the automatic steering unit 204 in the steering mechanism 2 can lift the brake disc 101 intercepted by the bracket 202 and can also perform azimuth steering; at this time, the second conveyor line 3 conveys the hub 102 towards the automatic steering unit 204. When the hub 102 conveyed on the second conveyor line 3 passes by the assembled robotic arm 4, the assembled robotic arm 4 grabs the hub 102 and installs the hub 102 onto the brake disc 101 on the automatic steering unit 204. Furthermore, the hub 102 and the brake disc 101 achieve automatic combined installation. Compared with the existing semi-automatic processing method using manual labor and machines, this hub automatic assembly machine can achieve automatic installation, reduce the labor intensity of workers, and improve work efficiency.

[0045] In a possible implementation manner, as Figure 2 shown, the automatic steering unit 204 includes a rotating seat 205 and a servo motor 206.

The servo motor 206 has high precision and can achieve precise steering of the brake disc 101.

The first sliding assembly includes a slide rail installed on the installation plate 9 and a slider installed on the side surface of the bracket 202. The slider is slidably installed on the slide rail, so that the bracket 202 can lift in the vertical direction.

In order to ensure that the second top extension cylinder 203 can drive the automatic steering unit 204 to lift in the Z-axis direction, a second sliding assembly is provided between the automatic steering unit 204 and the installation plate 10. The second sliding assembly includes a sliding seat installed on the servo motor 206 and a slide rail installed on the side surface of the installation plate 10.

When the jaws 7 need to grasp the hub 102, the output shafts at both ends of the jaw cylinder 6 contract, and the contracting output shafts drive the two jaws 7 to perform a clamping action, so as to clamp the hub 102.
