Abstract
The invention relates to the technical field of cutters applicable to large-diameter deep-hole machining, and particularly relates to a radial adjustable deep-hole boring cutter for guide blocks. The radial adjustable deep-hole boring cutter comprises a cutter bar, the front end of the cutter bar is provided with a guide block radial-adjusting mechanism, a guide block is arranged at the front end of the guide block radial-adjusting mechanism, the guide block is fastened on a guide block seat, the front end of the guide block seat is provided with a cutter apron, a blade is fixedly arranged in the cutter apron, the guide block radial-adjusting mechanism comprises a base connected with the cutter bar, a body is arranged on the base, a linkage disc is arranged on a shaft sleeve of the body, one side of the linkage disc is provided with a conical tooth structure, and three small conical gears are arranged in three holes uniformly distributed on the circumference of the body in a clearance fit mode. Through arranging a radial adjustable guide mechanism for deep-hole boring cutters, the radial dimension of the guide block can be adjusted according to the overhanging length of a cutter nose so as to satisfy the guide demands of deep holes with different hole-diameters in the process of machining, and therefore, the boring cutter is simple and rapid in operation and high in precision, and the cost of the cutter is reduced while the quality of machined surfaces of deep holes is ensured.
Description
Technical field: [0001] The invention relates to the technical field of cutting tools suitable for machining large-diameter deep holes, in particular to a deep-hole boring tool with radially adjustable guide blocks. Background technique: [0002] In the manufacturing fields of aerospace machinery, petroleum machinery and mining machinery, large-diameter deep holes are often processed. The boring process of this type of hole generally adopts a boring tool structure with a guide block. The guide block is fastened on the circumference of the boring head near the tool tip by welding or machine clamping. It is only suitable for the processing of fixed-size deep holes. When processing deep holes with different diameters, it is necessary to replace the boring heads corresponding to the diameters, the cutting tool technology range is narrow, and the cost is high. Invention content: [0003] The present invention provides a radially adjustable deep-hole boring tool for the deficie...
