Embodiment Construction
[0011] A precision machining method for a slender shaft supported by a cross wing, which adopts the following steps: a. Aluminum block clamps pressed against it and located on the left and right sides of a workpiece 1 are arranged on the machine tool workbench, and the aluminum block clamps are composed of several pieces It is composed of aluminum block bodies 2 distributed at intervals in the front and back; b. The upper surface of the middle part of the two aluminum block fixtures is processed into a workpiece placement groove 3 with the same width as the workpiece 1. The side and bottom surfaces of the workpiece placement groove 3 should reach the machine tool performance for eliminating clamping deformation Guarantee the highest precision; c. Use the left wing end surface of the workpiece 1 as the positioning reference plane, close to the left side of the workpiece placement groove 3, and install it firmly on the workpiece placement groove 3 with your hands, and apply 502 qu...

The invention in particular relates to a precision machining method for a long and thin shaft of a cross-shaped wing bearing, which aims at solving the problem that precision is difficult to guarantee when a long and thin shaft of an existing cross-shaped wing bearing is processed. The precision machining method comprises the following steps: a, arranging a plurality of aluminum block fixtures composed of an aluminum block body on a working table of a machine tool; b, processing workpiece placing slots in the upper surfaces of the middle parts of two aluminum block fixtures; c, mounting on the workpiece placing slots by taking a work piece left wing end face as a positioning reference surface, and gluing at a seam by adopting 502 quick-dry super glue until a workpiece is fixed and then loosening the workpiece; d, after the positioning reference surface of the workpiece is checked to be qualified with a meter, starting to carry out finish machining; e, sequentially processing the upper wing end face, the left side, the right side, side surfaces of a left wing and a right wing and end faces of the left wing and the right wing above the aluminum block fixture, and meanwhile, measuring the thickness dimension of the workpiece; and f, unloading the workpiece and turning out the workpiece for 180 degrees, repeating the steps c, d and e until processing of the workpiece is completed, and unloading the workpiece. The precision machining method provided by the invention has the advantages that the machining quality precision degree is high, the production demand is met and the production efficiency is relatively high.
Description
technical field [0001] The invention relates to the technical field of precision machining applications, in particular to a precision machining method for a cross wing supporting a slender shaft. Background technique [0002] The slender shaft of the cross-wing support is a high-precision component. Because of its thin structure and special-shaped structure, it brings difficulties to ensure the accuracy in the process of processing. When clamping, the clamping force can easily cause distortion, deflection, and deformation to the workpiece, causing the workpiece to rebound as soon as the clamping force is removed. The rebound causes product flatness, cylindricity, coaxiality, and inner hole There are serious out-of-tolerances in the circle size, etc., and the out-of-tolerance caused by clamping deformation is the most important factor for the out-of-tolerance of product accuracy. The machining accuracy of the machine tool has accounted for more than half of the accuracy to b...
