Servo annular nozzle device

Abstract

The invention belongs to the technical field of mechanical machining, and particularly relates to a servo annular nozzle device. The servo annular nozzle device is composed of a fixed inner ring, a rotary outer ring, a nozzle, a lower supporting plate, a servo motor and a transmission device. The rotary outer ring is arranged on the fixed inner ring in a sleeved manner and is supported and positioned through the lower supporting plate installed at the bottom of the fixed inner ring. The rotary outer ring is provided with an annular cavity and forms a sealed flow channel with the fixed inner ring. The bottom of the annular cavity is provided with a water outlet, and the nozzle is installed on the water outlet. The fixed inner ring is provided with a water inlet corresponding to the annularcavity. The rotary outer ring is connected with the servo motor through the transmission device and can rotate around the center axis of the servo motor under the action of the servo motor; and the servo motor is installed on the fixed inner ring. The servo annular nozzle device is simple in structure, real-time tracking cooling of machined points can be achieved, and the cooling effect is fully guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of mechanical processing, and particularly relates to a servo ring nozzle device. Background technique [0002] At present, there are two main cooling methods for grinding heads in machining: one is to use single or multiple nozzles to cool specific processing points. This method has narrow cooling range, easy to produce circumferential gaps, and uneven cooling. And other defects, resulting in insufficient processing and cooling, high product rejection rate, and a great impact on the life of the grinding head; another cooling method is to use an annular water curtain for cooling, which requires a large water flow For the centralized water delivery of multiple machine tools, the circulating water consumption is too large, which is easy to cause waste of resources. At the same time, the waterproof level of the machine tool guard is also high, which is easy to increase the production cost of the machine tool. Summa...
