Embodiment Construction

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] A method for detecting the geometric accuracy of a vertical machine tool with an external support, comprising the following steps:

[0025] Step (1), installing the composite inspection tool 1 on the rotary table 2; the composite inspection tool 1 includes a square 11 in the shape of a cuboid, and a top 12 arranged on the top of the square 11 in the direction of its central axis;

[0026] Step (2), correcting the coaxiality of the central axis of the compound inspection tool relative to the central axis C of the rotary table, specifically fixing the magnetic base 3, pointing the needle 31 to the outer cone of the top 12, and starting the rotary table 2 to rotate at a constant speed , adjust the coaxiality according to the deviation value on the dial 32 until the deviation value is zero;

[0027] The purpose of this step is to adjust...

Abstract

The invention discloses a geometric precision testing method for a vertical machine tool with an external bracket, wherein the method is applied to the field of machine tool precision testing. The method comprises the following steps of (1), mounting a composite testing fixture on a rotating worktable, wherein the composite testing fixture comprises a cuboid angle square, and a finial which is arranged at top of the angle square and is in the direction of the central axis; (2), correcting coaxiality of the central axis of the composite testing fixture relative to the C axis of the central axisof the rotating worktable; and (3)-(6), respectively measuring the parallelism among the X-direction, the Y-direction and the Z-direction of a large vertical column and a small vertical column, and the verticality between the X-direction and the Y-direction. A testing fixture which is adopted in the current testing method is a cylindrical testing fixture. The cylindrical testing fixture can onlytest the large vertical column which operates with a cutter rest, and the small vertical column which operates with an external bracket. The parallelism relative to a main axis, the parallelism relative to a horizontal direction (XY direction) and the verticality of the XY direction are not effectively tested. The geometric precision testing method can effectively settle the problem.

Description

technical field [0001] The invention belongs to the field of machine tool precision testing, and in particular relates to a geometric precision testing method of a vertical machine tool with an external support. Background technique [0002] With the development of machine tools towards high speed and high precision, the requirements for machining precision of gears are also getting higher and higher. As an important equipment for gear processing, the vertical machine tool with outer support has a particularly important geometric accuracy. A machine tool with high geometric precision is the premise and basis for processing gear products that meet the precision requirements. [0003] At present, for the geometric accuracy detection method of the vertical machine tool with external support, because the inspection tool used is a round rod type inspection tool, it can only detect the large column running with the tool holder and the small column running with the external suppor...
