The invention relates to the technical field of hardware machinery, and discloses an auxiliary chamfering device capable of solving problems of dust
diffusion and difficulty in steering and applicable to a hardware workpiece. The auxiliary chamfering device comprises a shell, and the bottom of the shell is fixedly connected with a main table. The workpiece is automatically extruded and fixed, the workpiece is prevented from moving in the chamfering process, chamfering operation can be smoothly carried out, dust collection operation is triggered while fixing is carried out, linkage between structures is improved, and the
automation degree is high; the dust collection operation is automatically started through the combined action of a placing table, a suction head and a fan, dust generated by chamfering is automatically absorbed, the situation that the air quality is affected due to dust
diffusion is avoided, complex cleaning operation is omitted, the two hands are liberated, and the
workload is effectively reduced; through the combined action of a rotating button, a cone
pulley and the placing table, according to the actual
machining requirements, the workpiece is in a fixed state and automatically steers, corner angles of different angles can be ground conveniently, operation is convenient and fast, and the
actual use requirements are better met.
