Abstract
The invention relates to a method for integrally manufacturing a small turntable U-shaped support, which comprises the following steps of: (1) feeding a beam, semi-accurately machining the beam, thermally stabilizing the semi-accurately machined beam, and reserving machining allowance at the axis hole and the end face thereof; feeding a left column, semi-accurately machining the column, thermally stabilizing the semi-accurately machined column, accurately machining the left column, and reserving machining allowance at the axis hole and the end face thereof; feeding a right column, semi-accurately machining the column, thermally stabilizing the right column, finally accurately machining the right column, and reserving machining allowance at the axis hole and the end face thereof; (2) integrally assembling the beam, the left column and the right column to form the U-shaped support; (3) carrying out thermal stabilization treatment, artificial ageing or natural ageing stabilization treatment; (4) machining the whole assembly to complete the axis hole and the end face therefore and complete all dimensions; and (5) detecting the decision to form the finished product of the U-shaped support.
Description
Technical field
The invention belongs to the manufacturing technology field of small-sized turntable combined type U type support, realization has the integrated manufacturing of the U type support of the coaxial coplane axis hole of high accuracy characteristic.
Background technology
Tracing measurement system generally adopts the visual field of Horizon ceremony design of mini turntable realization probe unit to move and change; U type support is as the main connecting elements of realizing the motion coupling of azimuth axle and pitch axis system, and its structure precision and stability directly influence the function and the performance of Detection And Tracking system.
U type support can be divided into monolithic construction, welded structure, fabricated structure, and small-sized turntable U type support generally adopts fabricated structure.U type support generally can be divided into crossbeam, left pillar, right pillar, and to the performance impact maximum is the axiality of left pillar, right shore supports axis and the orthogonality of orientation and pitch axis.This characteristic performance is by for to be distributed in two axis (azimuth axis and pitch axis) with quadrature coplane of three assemblies, and the aspects decisions such as form, combination precision, stability of confirming three end faces and three axis holes of this axis.
Summary of the invention
Main purpose of the present invention is to improve precision stability after the processing of U type support, reduces detection and the periodic duty of adjustment in the assembly assembling process, improves the relative positional accuracy of axis hole.
The integrated manufacturing method of this small-sized turntable U type support may further comprise the steps:
The first step: at first crossbeam blanking, half smart machining is carried out thermostabilization with the crossbeam after the semifinishing then and is handled, and carries out the crossbeam machine finishing at last, reserves allowance at axis axis hole and end thereof;
Simultaneously, the left column blanking, half smart machining is carried out thermostabilization with the left column after the semifinishing then and is handled, and carries out the left column machine finishing at last, reserves allowance at axis axis hole and end thereof;
Simultaneously, the right column blanking, half smart machining is carried out thermostabilization with the right column after the semifinishing then and is handled, and carries out the right column machine finishing at last, reserves allowance at axis axis hole and end thereof;
Second step:, form U type support with the integrated assembling of crossbeam, left column, right column after the first step processing;
The 3rd step: U type support is carried out thermostabilization processing, artificial aging or natrual ageing stabilization processes;
The 4th step: with the whole machining of assembly, accomplish axis axis hole and end face thereof, accomplish all sizes;
The 5th step: accuracy detection forms U type support finished product.

Right pillar manufacturing, according to the machining of mechanical technology flow process part, axis axis hole and end face thereof are reserved 1～2mm allowance.
U type support is integrated, repaiies the butt joint of grinding crossbeam, left pillar, right pillar end face is installed, and be connected according to assembly technology completion screw.
Carry out thermostabilization processing, manual work or natural aging treatment afterwards.Thermostabilization is handled, and artificial aging or natural aging treatment are confirmed different temperature parameter, aging time or the like according to the material properties of zero parts, the difference of architectural feature.
The integrated manufacturing of U type support installs and fixes U type support on lathe, utilize lathe to find the coplane axis accurately, and deviation is not more than 0.02mm.Triaxial hole that coplane is coaxial and end face processing thereof put in place.Add each processing in man-hour amount of feeding and be no more than 0.5mm, the finishing feed amount is no more than 0.1mm.
Meet figure paper size and specification requirement through accuracy detection, form U type support finished product.
