Description

Brittle material processing head cooling device

Technical Field

Background

At present, common cooling modes are adopted on equipment such as a conventional machining center, a lathe and the like, and cooling liquid is sprayed to a product to be machined below a main shaft through a fixed nozzle.

The working principle of the cooling system of the machining center is as follows: the cooling liquid is pumped by the centrifugal pump and then is divided into two paths, one path is directly connected to a nozzle on a workpiece housing (a main shaft sleeve), and the other path is connected to a spray pipe in a main shaft hole of the workpiece to a grinding region. Separate ball valves are provided on both coolant passages to regulate coolant flow. The cooling liquid with grinding through the grinding area flows back to the cooling box from the water outlet pipe at the back of the lathe bed, and the filtered and precipitated cooling liquid is continuously used under the action of the filter screen and the partition plate.

However, for silicon and quartz materials, the spraying angle of the nozzle cannot be adjusted, the size and the dimension of the silicon and quartz materials are changed frequently, and cooling water spraying at a fixed angle is easy to cause insufficient spraying water quantity aiming at the silicon and quartz materials or incomplete infiltration, so that the expected spraying water quantity cannot be reached, and the produced products are bad and scrapped. For example: the diameter change span of the cutter is large (from 2mm to 76 mm) when the silicon and quartz are needed, and the phenomenon that the heat generated by the cutter and the workpiece cannot be conducted away in time because the cooling liquid is not cooled in place during processing usually occurs, so that the workpiece is abnormal is caused.

Based on this, the present utility model has been proposed.

The hinge is preferably an XD type hinge of Rui Cheng hardware factory in the city of Yinyang, and after the direction of the nozzle 40 is adjusted, the hinge is screwed down by a screw, so that the spraying direction of the nozzle 40 is unchanged.

In addition, the cooling liquid in the annular water distributor 20 is aligned to the main shaft 12 and the workpiece to be processed below the main shaft through the inclined pipe 23, so that the main shaft 12 and the workpiece to be processed below the main shaft can be completely infiltrated by the cooling liquid, and the cooling effect is ensured.
