Automatic feeding mechanism for double bedding faces of cast grinding pliers

The invention relates to an automatic feeding mechanism for double bedding faces of cast grinding pliers. The automatic feeding mechanism is structurally characterized in that a guide groove is arranged in a guide plate, a lower sliding plate is arranged at the bottom of the guide groove and is slidably connected with the same, one end of the lower sliding plate is vertically upwards and is located on the running route of an upper sliding plate, one end of a tension spring is connected to the other end of the lower sliding plate while the other end is connected with a support, the upper sliding plate is arranged in the guide groove and is located on the lower sliding plate, one end of the upper sliding plate is connected with a nut sleeving a feeding screw, the feeding screw is connected with a servo motor, a discharge chute is arranged in a feeding trough plate, a pushing plate is arranged in the discharge chute, and one end of the pushing plate is connected with a pushing cylinder. By the arrangement, the shortcoming brought by the fact that cast grinding is totally artificially completed is overcome; the feeding mechanism is especially designed for the double bedding faces of the cast grinding pliers, thereby being quite convenient to adjust; feeding and discharging are automatically performed under the program control, automatic production is realized, multiple devices can be looked after by one person, production efficiency is high, and labor intensity is low.
