Embodiment

[0022] A processing method of double inner cone positioning block with low eccentricity difference, such as Figure 5 As shown, the positioning block is composed of a first inner cone surface 3 and a second inner cone surface 1 machined on two end faces of the positioning block 2, which in turn includes the following steps:

[0023] Clamp the positioning block on the machine tool turntable, such as figure 1 As shown, the first inner cone surface is processed on the end surface of the positioning block;

[0024] Remove the positioning block for processing the first inner cone surface from the machine tool;

[0025] Clamp the auxiliary block on the turntable of the machine tool, and machine the end surface of the auxiliary block into an outer cone 4, such as figure 2 Shown

[0026] Such as image 3 As shown, the outer cone surface of the auxiliary block is fixedly assembled with the first inner cone surface of the positioning block, and the second inner cone surface 1 is machined on th...

Abstract

The invention belongs to the technical field of ultraprecision machining, and particularly relates to a machining method of a low-eccentric-error dual inner conical face positioning block. In order toreduce the dual inner conical face eccentric errors, and solve the problem of reduction of positioning precision caused by the eccentric errors, a first inner conical face is machined, an outer conical face is machined on an auxiliary block, the outer conical face and the first inner conical face are matched online, a second inner conical face is machined and made, in the machining process, the axis of the inner conical face and the axis of the outer conical face copy the precision of a machine tool shaft, clamping and positioning difficulty is reduced, and a three-axis machine tool is used for achieving machining of the low-eccentric-error dual inner conical face positioning block. According to the technical scheme, the method is suitable for machining of the dual inner conical face positioning block, and is also suitable for machining of dual-face lenses with the high eccentric error needs.

Description

Technical field [0001] The invention belongs to the technical field of ultra-precision processing, and specifically relates to a processing method of a positioning block. Background technique [0002] The double inner cone positioning block realizes high-precision positioning of the workpiece by self-centering. The smaller the eccentricity difference of the double inner cone positioning block, the smaller the eccentricity of the workpiece. In the traditional machining process, it needs to be clamped twice. First, the side wall of the double inner cone positioning block is processed into a cylindrical surface, and then an inner cone is processed on one of the end surfaces, and then the cylindrical side wall is used as the reference, and the dial indicator is used. The method divides the double inner cone positioning block, because it depends on the side wall cylinder for positioning, if the cylinder axis is not perpendicular to the machine tool table, there is an angle between the...
