Grinding device for burrs on surface of round-link chain

The round-link chain surface burr grinding device comprises a shell, a machining channel penetrating left and right is formed in the shell, an air inlet communicating with the top face of the shell is formed in the top wall of the machining channel, and a rear air outlet communicating with the rear surface of the shell is formed in the rear wall of the machining channel; the round-link chain is fixed to the upper side of the sliding groove through the extrusion block in the deburring machine, the fixing device can fix the round-link chains of different sizes, welding burrs can be efficiently removed, the fixing device is faster than manual deburring, bidirectional positioning is carried out in a machining channel, the four faces of the round-link chain are polished while positioning is carried out, and the machining efficiency is improved. The machining continuity and efficiency are guaranteed, the production cost is reduced, manual intervention is reduced, grinding dust is collected while grinding is conduct
