Machining auxiliary clamp for angle centripetal holes of annular part and machining method thereof

Abstract

The invention relates to a machining auxiliary clamp for angle centripetal holes of an annular part. The machining auxiliary clamp is simple in structure; the angle of a workpiece clamp can be adjusted by a fixing clamp according to the angle centripetal holes needed by the annular part; the height of the fixing clamp is adjustable and is kept consistent with that of the workpiece clamp; the annular part is pressed to be machined conveniently; a positioning hole and a positioning rod are arranged on a workpiece fixing portion of the workpiece clamp; and during machining of the angle centripetal holes of the annular part, the hole center distances of every two adjacent angle centripetal holes can be the same. According to the machining method of the angle centripetal holes of the annular part, at least two machining auxiliary clamps for the angle centripetal holes of the annular part are used, a machining station is arranged between two workpiece clamps, the annular part is placed in positioning grooves of two workpiece positioning portions, the part, located at the machining station, of the annular part is the milling cutter machining position of a numerical control horizontal boring and milling machine, and positioning holes and positioning rods of the workpiece clamps are used in cooperation, so that machining of the angle centripetal holes of the annular part is achieved, and the hole center distances of every two adjacent angle centripetal holes are the same.

Description

technical field [0001] The invention relates to the field of mechanical processing, more specifically, it relates to an auxiliary jig for processing an angular centripetal hole of an annular part and a processing method thereof. Background technique [0002] Ring parts are a common type of parts in machining. To process angled centripetal holes on ring parts, it is necessary to ensure that the spatial angle of each hole is consistent, each hole faces the center of the ring part, and the hole distance tolerance must meet the requirements. , so ring parts are difficult to process products. At present, the production of annular parts with angular centripetal holes requires the use of five-axis linkage CNC machine tools, but the cost of purchasing five-axis linkage CNC machine tools is relatively high, and the annular parts with angular centripetal holes cannot be processed on CNC horizontal boring and milling machines. Therefore, it is necessary to propose a new processing aux...
