The invention discloses an auxiliary working table for notebook shell machining in the field of electronic component machining. The auxiliary working table for the notebook shell machining comprises arack; a working plate is detachably connected at the upper end of the rack and a plurality of leakage holes are formed in the working plate; a dust collecting groove is arranged under the working plate and an arc-shaped sliding way is arranged below the dust collecting groove; a driving chamber is arranged below the sliding way and a crushing chamber is arranged at the outer side of the driving chamber; the sliding way communicates with the crushing chamber; a steel wire mesh which communicates with the sliding way is arranged at the top of the driving chamber; a double shaft extension motoris arranged in the driving chamber and the upper end of the double shaft extension motor is connected with a negative pressure screw propeller and a swinging arm; a swinging rod which is connected inthe sliding way in a striding manner is arranged at the top end of the swinging arm; a crushing mechanism is connected with the lower end of the double shaft extension motor; the crushing mechanism comprises an extruding plate which is located in the crushing chamber; a material collecting groove communicates with the bottom of the crushing chamber and an exhaust pipe which communicates with the material collecting groove is arranged at the lower end of the driving chamber. By means of the auxiliary working table, the problem that the machining is affected by fragments and waste materials produced during the prior notebook shell machining is solved.
