Finish machining method of the frame of the rotating table

Abstract

A fine machining method of the rolling stand frame belongs to machine finishing technology field. At first determining center of turning circle position of the fine boring machine table and mounting end face multiple tooth circular dividing table thereon, the tetrahedron is mounted on the end face multiple tooth circular dividing table, and adjusting it to collimate with the photoelectricity autocollimation to determine machineable machine zero position point; the rolling stand frame is mounted on the worktable, and adjusting it to symmetry with the center of gyration; boring the frame side face of each axle hole for the rolling stand frame and the axle hole until achieving to the required precise size, when the frame rotates from one side to another side, rotating relevant angle of the worktable contrasting to graduation value of the end face multiple tooth circular dividing table, the tetrahedron is measured by the photoelectricity autocollimation, fine tuning the worktable to collimate the corresponding face of the tetrahedron with the sending beam of the photoelectricity autocollimation, at this point, the rotating angle is exact value, then processing. The invention operates conveniently and audio-visually, with reliable processing manufacturability, and reducing accumulation of error and improving process precision of the frame.

Description

technical field [0001] The invention belongs to the technical field of mechanical finishing. Background technique [0002] The turntable is a device for calibration, testing and inspection of inertial devices, and its precision requirements are particularly high. The turntable body is mainly composed of base, frame and shafting. The frame is an important part of the turntable, and its accuracy largely determines the accuracy of the turntable body. The turntable frame has the characteristics of large size, complex structure, strict symmetry requirements, high rigidity, high strength, light weight, high design precision requirements, and good stability. Therefore, the production and processing of the turntable frame is mainly completed through precision casting, heat treatment, scraping, machining, stability treatment, precision machining and other processes. Its technological characteristics are high processing precision, high processing difficulty and high assembly precis...

Problems solved by technology

This method can reduce the cost of frame processing and ensure the technological requirements and processing monitoring requirements of frame processing. However, in the process of frame processing, measuring tools must be calibrated in each process to ensure the accuracy of processing benchmarks, resulting in long frame processing production cycles and cumbersome operations. , at the same time, due to the accumulation of various errors during the calibration process, the machining accuracy of the frame is reduced

This method cannot meet the high-precision frame processing requirements
