Abstract:
A precast hole scab removing device is provided. The precast hole scab removing device is composed of a stand, floating columns, ejector pins, an air cylinder, clamp cylinders, supporting poles and the like. In use, a hole I and a hole II in a workpiece respectively match with a tapered part of a left floating column and a tapered part of a right floating column; by pressing down the workpiece, locating parts of the workpiece simultaneously match with the top end of a supporting pole I, the top end of a supporting pole II and the top end of a supporting pole III, a clamp cylinder I, a clamp cylinder II and a clamp cylinder III press the workpiece tightly, and at the moment, the workpiece is completely located; the air cylinder lifts down a lifting plate and the ejector pins through two guide pillars, the ejector pins are pressed into holes, in which scabs need to be removed, of the workpiece; and therefore, the scabs can be ejected out of the workpiece. The precast hole scab removing device can remove the scabs of precast holes of casting workpieces in use, the removing efficiency is high, the scabs are removed cleanly, and additionally, the precast hole scab removing device has the characteristics of high automation degree, simple structure, low manufacturing costs and the like.
