Cooling and vibration reduction tool bar applied to machining for large-pitch screw rod

Abstract

The invention discloses a cooling and vibration reduction tool bar applied to machining for a large-pitch screw rod, and belongs to the technical field of machining. Aiming at the existing problems, the invention provides a cooling and vibration reduction tool bar applicable to a wide vibration frequency band, and solving the problems of high instantaneous vibration amplitude, poor cooling effectof multi-edge cutting, and the like. The invention discloses a cooling and vibration reduction tool bar applied to machining for a large-pitch screw rod. The cooling and vibration reduction tool bar applied to machining for the large-pitch screw rod comprises a cooling unit, a tool bar body, a tool bar head, a turning tool, a vibration reduction unit and a protection ring, wherein the vibration reduction unit is located at a groove of the tool bar body; a bulge part of the tool bar head is matched with the groove of the tool bar body, and fixes the vibration reduction unit; the turning tool isfixed to one end away from the bulge part, of the tool bar head; the cooling unit comprises a cooling spray head, a cooling liquid branch flow channel, a cooling liquid turning joint, a cooling liquid flow-distribution joint, a cooling liquid main flow channel and a cooling liquid connection hole; the cooling liquid branch flow channel is formed in the tool bar head and communicates with the cooling spray head; and the cooling spray head is arranged on one end surface for fixing the turning tool, of the tool bar head. The cooling and vibration reduction tool bar applied to machining for the large-pitch screw rod is mainly applied to machining for the large-pitch screw rod.

Description

technical field [0001] The invention relates to a cooling and vibration-damping cutter bar used in the processing of large-pitch screw rods, and belongs to the technical field of mechanical processing. Background technique [0002] Large-pitch screw parts are common important parts in large-scale equipment, such as large-scale press adjustment screws, main shaft ends and fastening screws of large-scale ship propellers, extrusion screws in plastic and rubber industry equipment, and wind power equipment. Bolts and more. In the application of large-pitch screw parts, often due to the problem of its manufacturing accuracy, problems such as thread disorder during the working process, poor motion accuracy and positioning accuracy are often caused, and the main cause of these problems is tool vibration during screw processing . In the processing of large-pitch screw, due to its characteristics of high feed, large depth of cut, and large load, it causes obvious vibration during th...
