AI Technical Summary

Technical Problem

In the existing technology, during the manufacturing process of brake disc sand cores, residual coated sand at the sand inlet requires an additional grinding process, which limits production efficiency.

Method used

A brake disc sand core conveying and grinding device is designed. It adopts a lifting bracket and an elastic telescopic rod in conjunction with a fixing block to realize the automatic positioning and fixing of the sand core. Combined with the grinding device, the sand inlet position is automatically ground during the conveying process. The lifting bracket drives the sand core down to the grinding position and realizes automatic opening and closing through the grinding motor.

Benefits of technology

The sand core inlet can be cleaned without additional grinding, which improves production efficiency and saves energy and controls production costs by automatically starting and closing the grinding motor.

Abstract

The brake disc sand core conveying and grinding device comprises a conveyor, a grinding device body and a lifting support, an electric roller is arranged on the lifting support, two elastic telescopic rods are horizontally and slidably connected to the top end of the lifting support, and fixing blocks are arranged at the ends, close to each other, of the two elastic telescopic rods correspondingly; and a driving mechanism for driving the elastic telescopic rod to slide is arranged on the lifting bracket. After the lifting support takes out the sand core, the driving mechanism drives the elastic telescopic rod to slide, and then the fixing block is driven to position and fix the sand core. The lifting support drives the sand core to descend to the operation position of the grinding device, a sand inlet in the position of a center hole of the sand core is ground, then the lifting support lifts the sand core to the position flush with the top end of the conveyor, and the electric roller is started to transfer the ground sand core to the conveyor. And the sand inlet of the sand core is polished and cleaned in the discharging and conveying processes, and no extra working procedure is needed. The device has the effect of improving the production efficiency of the sand core.
