the bearing frame comprises a bearing disc and a connecting part, wherein the connecting part is coaxially arranged at the bottom of the bearing disc, external threads matched with the threaded holes are arranged on the connecting part, and a fixing assembly for fixing the glass sand core funnel is arranged on the bearing disc.
As a further improvement of the utility model, the bearing plate is cylindrical, one end of the bearing plate is coaxially provided with a circular bearing groove, and the other end of the bearing plate is coaxially connected with the cylindrical connecting part.
As a further improvement of the utility model, the fixing component comprises a large clamping groove and a small clamping groove which are arranged on the side face of the bearing disc and are communicated with the bearing groove, and the large clamping groove and the small clamping groove are oppositely arranged.
As a further improvement of the utility model, the bottom of the bearing groove is coaxially provided with a central through hole penetrating through the connecting part.
As a further improvement of the utility model, the edges of the bearing groove, the large clamping groove and the small clamping groove are provided with fillets.
The beneficial effects of the utility model are as follows: the utility model solves the problem of data fluctuation caused by the fact that a glass sand core funnel is not fixed on a platform in the prior art. The fixing device is simple, small in size, convenient to use, stable in placement and low in price, and the glass sand core hopper can be stably placed on the balance disc by adopting the device for weighing the glass sand core hopper, so that the speed and the efficiency of weighing operation can be improved, and the precision of a result can be improved.
