High-pressure cooling device of milling machine cutter

Abstract

The invention discloses a high-pressure cooling device of a milling machine cutter. The high-pressure cooling device of the milling machine cutter comprises a cutter body, a bearing, an oil seal, a bearing bracket, a gland, a spring, an oil guide plate, a blind rivet and a milling cutter head, wherein the external conical end of an ST50 milling cutter body is connected with a milling tool inner conical hole to transmit the driving force; a vertical oil guide hole is formed in the parallel end of the milling cutter body; a conical cavity is formed in the interior of the milling cutter body; the milling cutter head is mounted in the conical cavity; a threaded hole is formed in the small-diameter end of the milling cutter head; the blind rivet is fixedly connected with the threaded hole of the small-diameter end through a threaded hole formed in the conical end of the cutter body; the blind rivet is hollow; a vertical through hole is formed in the junction between the blind rivet and the vertical oil guide hole of the cutter body; the parallel end of the cutter body is wrapped by an assembled part which is formed by the bearing, the oil seal and the bearing bracket; the lower end of the bearing bracket is connected with an assembled part which is formed by the gland and the spring; the oil guide plate is connected to the other end of the assembled part which is formed by the gland and the spring. According to the high-pressure cooling device of the milling machine cutter, a cooling device of a milling cutter is additionally mounted at one end of the milling cutter body by using the original oil hole of the milling machine; the breakage of the cutter caused by high temperature is avoided; the production cost is effectively reduced.

Description

Technical field: [0001] The invention relates to the technical field of machining milling machines, in particular to a high-pressure cooling device for milling machine tools. Background technique: [0002] When large-scale milling machines process large holes and deep holes, because the machine tool is not designed with a high-pressure cooling device, it often causes damage to the tool, and the efficiency of processing the workpiece is low and the quality is also poor. How to design a cooling device for a milling machine is an urgent problem to be solved. Invention content: [0003] The purpose of the present invention is to propose an improvement plan for the cooling of parts of the existing large-scale milling machine. The original oil hole of the machine tool is used to design and refit the high-pressure cooling tool holder, which solves the cooling problem of deep-hole drilling and boring tools for large-scale equipment such as milling machines.
