Machining method for profile detection test sheet of diamond roller

Abstract

The invention provides a machining method for a profile detection test sheet of a diamond roller. The method includes the steps that a two-column jig boring machine is selected as a machining device, the diamond roller is installed in a boring head of the two-column jig boring machine through a self-made locating mandrel, the profile detection test sheet is installed on the machine face of the two-column jig boring machine through a pair of flat tongs, the machine face is moved, the profile detection test sheet is moved to and makes contact with the diamond roller, the two-column jig boring machine is started, and the diamond roller rotates at a high speed and is controlled to be fed towards the profile detection test sheet till the profile detection test sheet is ground by the diamond roller to be in a complete profile contour. By the adoption of the method, the two-column jig boring machine is introduced to grinding of the profile detection test sheet of the diamond roller for the first time, the machining task can be finished only through one device, the possibility of clamping and aligning errors and manual operation errors is reduced to the lowest extent, the profile machining accuracy of the profile detection test sheet is effectively improved, and meanwhile the detection accuracy of the size of the profile of the diamond roller is improved.

Description

technical field [0001] The invention belongs to the technical field of diamond roller quality detection, and in particular relates to a processing method of a diamond roller surface detection test piece. Background technique [0002] The surface accuracy of the tenon and tooth part of the blade of the aero-engine is very high, and there are many interrelated dimensions in the profile. If you want to accurately process the tenon and tooth part of the blade, the most effective way is to use high-precision diamond rollers. Grinding and shaping the tenon and tooth part of the blade once. [0003] In order to meet the surface accuracy of the tenon teeth of the blade, the diamond roller must have a higher surface accuracy. The profile of the diamond roller is the same as that of the mortise and tooth parts of the blade. They are closed curved surfaces composed of multiple interrelated curves around the central axis and around the central axis, and the profile of the diamond rolle...

[0006] However, using the above method to process the surface inspection test piece will inevitably bring in equipment accuracy errors. Since multiple clamping and alignment are required in the processing process, it will also bring in clamping and alignment errors and manual operation errors, thereby affecting The surface processing accuracy of the surface inspection test piece will directly lead to the reduction of the detection accuracy of the diamond roller surface size
