The invention discloses a centering mechanism for wheel hub punching. The centering mechanism comprises a working support, and two fine adjustment assemblies symmetrically arranged on two sides of the working support. Each fine adjustment assembly comprises a centering plate arranged on one side of the working support, a centering support connected to the centering plate and capable of sliding relative to the working support, photoelectric switches symmetrically arranged on an inner wall of the centering plate, and a firs driver for driving the centering support to move along the working support; the first drivers and the photoelectric switches are all connected to a control assembly. The two first drivers operate synchronously and the two centering supports are opposite in direction of movement. The two centering supports are used for adjusting positions of a hub; when location points of four photoelectric switches are all in contact with the hub, the location points of the four photoelectric switches are the center of the hub. The two centering supports are synchronous in movement and opposite in direction of movement; therefore, the position of the center of a circle defined by the location points of the four photoelectric switches does not change in the movement process of the centering supports, and the position of a hub punching center can be accurately determined in the process of adjusting the position of the hub.
Description
technical field [0001] The invention relates to the field of centering mechanisms of wheel hub punching dies, in particular to a centering mechanism for wheel hub punching. Background technique [0002] The casted wheel hub needs to be punched in the center of the wheel hub after casting. In order to ensure the precise punching position, the punching center is usually found first, and then the wheel hub is punched. In the prior art, the hub center is usually determined by manual measurement, which has a large measurement error range, resulting in inaccurate punching positions; in addition, there are some centering devices, but their structures are complicated, and the determined hub center position is inaccurate. Contents of the invention [0003] The object of the present invention is to provide a centering mechanism for wheel hub punching to adjust the position of the wheel hub and accurately determine the position of the hub punching center. [0004] For reaching this ...
