Problems solved by technology

[0002] The valve core hole on the wheel hub is formed by drilling on the rim after the wheel hub is manufactured. The valve core hole processing equipment in the prior art is generally semi-automatic and requires a lot of manpower. Chinese patent CN104889447A discloses a Automatic processing equipment for hub valve core holes, including manipulator unit, servo rotating device, conveyor belt unit, vision unit, drilling device and control cabinet, the servo rotating device is set as a device for clamping and rotating the hub; the vision unit includes setting The camera above the servo rotating device, the bracket for fixing the camera, the light source arranged on the bracket, the computer connected with the camera, and the visual unit are used to judge the position of the hub valve core boss and output the The corresponding coordinates of the position of the valve core boss; the drilling device is set as a device for processing the valve core hole on the wheel hub; however, due to the variety of types and models of the wheel hub, although the position of the hub valve core boss can be identified, it cannot be The model of the hub is identified and the thickness of the valve core boss of the hub is identified. In addition, the transmission unit has a single function and cannot center the hub, resulting in errors in subsequent positioning and processing work; Types of jigs and processing equipment corresponding to it can only be processed in the same batch of the same type of wheel at the same time. If other types of wheels are to be processed, the processing equipment needs to be adjusted or even replaced to meet the processing requirements, which still greatly limits Processing efficiency, and manual adjustment of fixtures and processing equipment is prone to errors, which can easily lead to defective products
