Description

Burr removing device for cam shaft Technical Field The utility model relates to the technical field of camshaft processing, in particular to a camshaft deburring device. Background The camshaft is a key component in an internal combustion engine for controlling the opening and closing of valves, ensuring the mixing of fuel and air and the discharge of exhaust gases. The motion time and the stroke of the valve are precisely controlled by the shape and the position of the cam, and the performance, the efficiency and the emission of the engine are directly affected. Camshafts are typically made of high strength alloy steel, precision machined and heat treated to ensure durability and precision. Therefore, deburring and polishing treatments are required to be performed on the blank member of the camshaft, otherwise, the burrs will form irregular protrusions on the surface of the camshaft, affecting the accuracy of the camshaft. Chinese patent discloses a bistrique device of camshaft burring [ CN202420207377.3, publication No. CN221936245U ] including first connecting rod and second connecting rod and rotatable brush that can move in opposite directions or opposite directions, all install the fixed establishment who is used for fixed camshaft on first connecting rod and the second connecting rod, one side fixedly connected with first motor of first connecting rod, and the output shaft of first motor runs through first connecting rod and is connected with fixed establishment, fixed establishment includes installation piece and thread bush, set up the screw thread on the installation piece, and installation piece and thread bush spin-in connection, one side fixedly connected with funnel type section of thick bamboo of thread bush, one side fixedly connected with a plurality of elasticity draw bars with funnel type section of thick bamboo matched with of installation piece.
