Grinding wheel cooling device, tool cooling system with same and cooling control method

Abstract

The invention discloses a grinding wheel cooling device, a tool cooling system with the same and a cooling control method. The grinding wheel cooling device comprises a blowing nozzle and a grinding wheel cooling nozzle, wherein the blowing nozzle and the grinding wheel cooling nozzle are sequentially arranged in the circumferential direction of a grinding wheel according to the rotating direction of the grinding wheel, the blowing nozzle and the grinding wheel cooling nozzle are located on the same side of a grinding machining area, the grinding wheel cooling nozzle faces the grinding machining area in the rotating direction of the grinding wheel, and the blowing nozzle is arranged in the reverse direction of the rotating direction of the grinding wheel. According to the grinding wheel cooling device, compact airflow can be formed by air blown out of the blowing nozzle, and the mode can act more effectively compared with a mode of cutting off high-pressure rotating airflow by liquid flow; and besides, on the premise that a liquid flow supply pump of the same specification is adopted, cooling liquid supply can be better guaranteed, the influence of high-pressure rotating airflow on cooling liquid entering the grinding machining area is reduced, and the technical problems of insufficient pressure and flow of the cooling liquid are solved.

Description

technical field [0001] The invention relates to the technical field of powerful grinding center cooling, in particular to a grinding wheel cooling device, a tool cooling system and a cooling control method thereof. Background technique [0002] The powerful grinding center can realize drilling, milling, powerful forming grinding and other processes in one clamping. It is a multi-process professional machine tool integrating drilling, milling and grinding. However, the existing powerful grinding centers still use common water spray cooling devices, which cannot achieve more efficient cooling. [0003] Most of the traditional cooling nozzle automatic follower devices use a single servo motor to drive the upper and lower screw rods to move up and down through two pulleys for cooling. This structure can only drive movement in one direction, and can only cool for one tool size. The appropriate cooling method cannot be selected according to the different tools. At the same time,...

Problems solved by technology

Therefore, during the power forming grinding process, the cutting heat in the grinding processing area cannot be effectively discharged, resulting in burnt workpieces and abrasives, thereby affecting the efficiency and quality of power forming grinding, which is also a bottleneck problem in the field of grinding technology

The Chinese patent with the authorized notification number CN 205237831 U discloses a coolant injection device suitable for a powerful forming grinder, including a high-pressure coolant nozzle and a medium-pressure coolant nozzle, the axial direction of the high-pressure coolant nozzle and the axis of the grinding wheel Parallel to the phase, the pipe wall of the high-pressure coolant nozzle is provided with a number of spray holes facing the circumferential surface of the grinding wheel, and the spray direction of the medium-pressure coolant nozzle is aligned with the tangent of the grinding processing area. The injection direction of the high-pressure coolant sprayed from the injection hole is perpendicular to the high-pressure airflow formed on the circumferential surface of the grinding wheel, thereby cutting off the high-pressure airflow. This scheme increases the amount of coolant entering the grinding processing area to a certain extent, but the use of liquid The effect of flow blocking airflow is limited, and the high-pressure cooling injection pipe will consume part of the flow of medium-pressure coolant, which may cause insufficient supply of medium-pressure coolant
