However, the existing punching device cannot clamp and fix camshafts of different sizes, has a narrow scope of application, and the clamping effect of the clamping mechanism is not good, which affects the punching accuracy. The clamping mechanism cannot rotate, and the angle of the camshaft needs to be manually adjusted to punch holes on the entire outer curved surface of the camshaft. The punching efficiency is low, and the debris generated during the punching process cannot be collected in time. The debris floats in the air and pollutes the processing environment, and the practicality is poor. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Summary of the invention

The debris falls into the collection box for collection, and an observation window is installed in the middle of the front side of the collection box. The amount of debris in the collection box can be visually seen through the observation window, which facilitates timely replacement of the collection box.

[0017] 5. The punching device for camshaft processing of the present invention has chip collecting boxes symmetrically fixedly connected to the lower left and right side surfaces of the box body.
