Abstract
The utility model discloses a parallel type constant-temperature feeding system for a numerical control drilling and milling machine tool. The parallel type constant-temperature feeding system comprises a ball screw pair, a motor base assembly, a nut base assembly, a bearing block assembly and a cooling system, wherein the motor base assembly, the nut base assembly, the bearing block assembly and the cooling system are fixedly connected to the ball screw pair. The cooling system comprises multiple spiral circulation cooling grooves which are formed in the motor base assembly, the nut base assembly and the bearing block assembly respectively. According to the parallel type constant-temperature feeding system for the numerical control drilling and milling machine tool, the spiral circulation cooling grooves are formed in the motor base assembly, the nut base assembly and the bearing block assembly respectively, when cooling media pass through the spiral circulation cooling grooves, heat, generated by high-speed movement, on the surfaces is taken away, and therefore heat deformation errors, caused by temperature raising, of the ball screw pair are reduced. The acceleration characteristic of the ball screw pair is improved, the system rigidity and the axial rigidity of the ball screw pair are increased, the elastic deformation in the moment of starting and stopping is reduced, and the transmission precision and the positioning precision of the machine tool are improved.
