PERCUSSIVE APPARATUS, REMOLDING INDEX TESTING SYSTEM OF A OBJECT HAVING THE SAME, AND REMOLDING INDEX TESTING METHOD OF A OBJECT

摘要

PURPOSE: A percussive device and a remolding index testing system and method of an object having the same are provided to improve the accuracy of a teat by accurately controlling the position of a balance weight. CONSTITUTION: A remolding index testing system of an object having a percussive device comprises a cylinder(110), an impact plate(121), a guide rod(122), an encoder(130), a balance weight(123), and an electromagnet holder(124). The impact plate covers the opened surface of the cylinder and is vertically movable along the inner surface of the cylinder. Both ends of the guide rod are connected to the impact plate and the encoder. The encoder is geared with the guide rod. The balance weight falls down along the outer surface of the guide rod. The electromagnet holder is arranged on the top of the balance weight to be vertically movable along the guide rod, and the balance weight is detachably arranged on the electromagnet holder. When the balance weight falls down, the electromagnet holder measures the height change of an object through the rotation of the encoder.
