Automatic detecting and mistake-proofing method and device thereof based on Renishaw probe

Abstract

The invention belongs to the technical field of mechanical processing and specifically relates to an automatic detecting and mistake-proofing method based on a Renishaw probe. A simple cutter corrector comprises a cutter detecting block [1], a quick-changing base [2], a bolt [3] and a base [4]. The working principle and the control system of the Renishaw probe of a numerical control machine are researched deeply; spatial distance, aperture and angle measurement micro programs are developed and a simple geometrical parameter calibration block for cutters is designed. The automatic detecting and mistake-proofing method comprises the steps of processing, measurement, judging and processing. In the method, collision accidents and scrapping of products, caused by the outside interference factors such as inaccurate origins of coordinates of workpieces, inaccurate geometrical parameters of cutters and inaccurate programs during numerical milling and processing, are avoided effectively. A correcting cutter has the characteristics of being used repeatedly, is simple and convenient to clamp, low in cost and good in universality. The technique is easy to understand, strong in operability and lower in degree of dependence to numerical control operators.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, in particular to an automatic detection and error prevention method based on a Renishaw probe. Background technique [0002] With the wide application of numerical control technology in the field of machinery manufacturing, the qualified rate of one-time processing of products has also been greatly improved. At the same time, some problems have also been exposed. In terms of precious and difficult-to-process ferrous metals in the aerospace field (such as: titanium alloy main rotor central parts, main rotor link parts, tail rotor link parts, etc. in the helicopter rotor system), the The inherent characteristics of such products are difficult to process, expensive, and have a long processing cycle.

AI Technical Summary

Problems solved by technology

In the process of processing, there are many interferences from external factors, the geometric parameters of the spindle tool are inconsistent with the geometric parameters required by the program, and the processing program is inconsistent with the program required for the processed product, which leads to some joint problems, ranging from quality problems to serious problems. Collision accidents between tools and workpieces or fixtures will accelerate the attenuation of machine tool machining accuracy. In addition, the production cycle of the product will be lengthened, which will seriously restrict the production progress and cause huge economic losses to the company.

The traditional error-proofing method is based on ordinary measuring tools and is observed with the naked eye. It relies heavily on human technology, focuses on experience, and has low detection accuracy. For today's era of high-efficiency CNC machining, this method is too old and difficult to meet the needs of modernization. CNC machining beats, so there is an urgent need for an automatic detection and error prevention method and device based on Renishaw probes, so as to ensure the safety of the processing process and the stability of product quality
