The briquetting back is equipped with the stopper of pressing close to the chamfer sword.

Slide top is located movable support and is equipped with guiding mechanism, and guiding mechanism is used for restricting movable support and only can follow longitudinal movement.

The working principle of the utility model is as follows: firstly, a cam shaft is clamped, then each driving device is started, a servo motor acts to transversely move a sliding plate to enable chamfering knives of each chamfering mechanism to align to a cam position of a cam shaft, meanwhile, the cam shaft clamping device drives the cam shaft to rotate, then, a cylinder pushes a sliding seat to enable the chamfering knives to be close to the cam for chamfering, a pressing block of each chamfering mechanism presses a cam surface, the cam rotates to push a whole movable support, a pressing spring enables the pressing block to always press the cam surface, therefore, the movable support can do profiling motion along with the cam surface, and the chamfering knives can chamfer the cam section completely.

The utility model discloses following beneficial effect has: 1. the chamfering mechanism can automatically perform copying motion along with the cam, so that the complete chamfering is ensured, and the chamfering precision is improved; 2. the rotary seat is arranged, the chamfering tool is arranged on the rotary seat, and the tool bit of the chamfering tool is in flexible contact with the cam through the reset spring, so that the condition that the size of a chamfer is not uniform due to machining errors is avoided; 3. a row of chamfering mechanisms are arranged on the movable support, a plurality of cams on the cam shaft can be processed simultaneously, and efficiency is improved.
