A self-reference detachable knife setting microscope and transfer translation observation method

Abstract

The present invention belongs to the technical field of precision machining and measurement, and discloses a self-reference detachable tool-setting microscope and an adapting translation observation method thereof. In order to solve the problem that the precious tool setting of a section profile and a tooth socket profile of a grinding wheel spindle is difficult to meet in the prior art, a self-reference installation mode through an adaptor on the basis of using a tool setting microscope with the same multiplying power, the same view field and the same object distance according to the amplification imaging principle based on a convex lens is provided. An I-shaped beam adapting translation method combines location regulation of a single point or two points of a loading and unloading structure to overcome the contradiction between the optical design parameters of the tool-setting microscope and the actual observation demands of the precious tool setting of the inner and outer teeth, achieve the precious tool setting of the section profile and the tooth socket profile of the grinding wheel spindle and achieve the detachability of the tool-setting microscope structure and easy installation and debugging in a compact space. The self-reference detachable tool-setting microscope and the adapting translation observation method thereof are simple and compact in structure, detachable, convenient and efficient in regulation and few in observation error sources, and have good market application prospects and promotion values.

Description

technical field [0001] The invention belongs to the technical field of precision machining and measurement, and relates to a self-reference detachable knife-setting microscope and a transfer translation observation method. Background technique [0002] Tool setting is to make the tool position point of the tool on the starting point (tool setting point) in the workpiece coordinate system, so that under the control of the NC program, the machined surface cut by the tool has a correct alignment with respect to the positioning reference. Dimensional relationship, so as to ensure the machining accuracy requirements of the parts. In CNC machining, the basic methods of tool setting include trial cutting method, tool setting microscope tool setting, ATC tool setting and automatic tool setting. The commonly used knife-setting microscopes are straight type and corner type. [0003] Grinding is a suitable method to improve surface finish and precision. In order to improve surface q...

Problems solved by technology

The forming method of gear grinding is based on the line contact between the grinding wheel and the workpiece gear. It modifies the cross-sectional profile of the grinding wheel shaft to be consistent with the profile of the tooth groove (or the contact line), and relies on the profile of the sand to ensure the accuracy of the grinding tooth profile. Therefore, The profile of the profile of the shaft section of the forming wheel and the profile of the tooth groove will directly affect the machining accuracy of the workpiece gear, and will also affect the operation of the CNC machine tool

[0004] The grinding wheel grinding assembly is an important part of the form gear grinding machine. During the grinding process of the grinding wheel and the workpiece gear, when the grinding wheel and the workpiece gear are in line contact with each other, it will have a certain impact on the rotating spindle of the grinding wheel, causing the grinding wheel The geometric eccentricity of the rotating spindle leads to the vibration of the grinding wheel grinding assembly, which in turn affects the dynamic grinding force of the grinding wheel, resulting in a large uncertain re-image error, which is not conducive to the improvement of the machining accuracy of the tooth surface. Based on this, through The rotary motion of the grinding wheel spindle adopts a flexible driving method, and the grinding process of the internal and external gears will be beneficial to improve this problem. The inherent optical axis and the clamping end of the tool are clamped and positioned by the cylindrical generatrix, so it cannot meet the microscopic tool setting requirements of the grinding wheel shaft section profile and tooth groove profile under the condition of the grinding wheel cantilever structure; the commonly used The structure of the tool setting microscope cannot be disassembled, which cannot meet the installation and debugging in the case of compact structure; in addition, the commonly used tool setting microscope can also use the magnetic table clamping method to perform tool setting on the workpiece. The parallel alignment of the datum plane of the knife microscope objective lens system is relatively difficult; there are large visual errors and installation positioning errors; the requirements for structural adaptability are relatively high and the magnetic base is difficult to fix on a non-magnetic structure
