Problems solved by technology

Since the detection location is a narrow and slender space, and the detection point is relatively special, the current detection method is to detect whether it is suitable by using a caliper, removing the plug with a feeler gauge, or observing with the naked eye. And it takes a long time to detect a product
In recent years, with the increase in the production of compressors, the actual value detection, data recording and detection efficiency of each tenon assembly accuracy of each group of wheels of each compressor are particularly important. Existing measuring tools or visual observation Far from meeting customer needs

Abstract

The invention provides a device and method for detecting the convexity and concaveness of the tenon end surface and the wheel disk end surface of a compressor blade, belonging to the technical field of compressor blade detection, including a computer system for detecting the convexity and concaveness of the tenon end surface and the wheel disk end surface of each group of blades of the product The point laser detection assembly, the driving assembly used to connect with the first end shaft of the product to drive the product to rotate, the driven idler assembly and the driving idler assembly located at both ends of the product, are used to abut against the second end of the product The shaft is used to prevent the axial movement of the product, the axial rough positioning component, and the photoelectric sensor component for reset. The device adopts the method of point laser + reflector to realize the detection of the convexity and concaveness of the end face of the tenon of the blade and the end face of the wheel in a narrow space. It adopts non-contact detection, which avoids wear or damage to the product and improves the detection efficiency. The computer system is convenient for real-time statistics and data analysis of the qualified rate of blade assembly of similar products, saving manpower and reducing human errors.

Description

technical field [0001] The invention belongs to the technical field of compressor blade detection, and specifically discloses a device and method for detecting the convexity and concavity of a compressor blade tenon end face and a wheel disc end face. Background technique [0002] The assembly accuracy of the tenon of the compressor blade directly affects the assembly performance of the engine. After the assembly of the tenon is completed, the end face of the tenon may be higher or lower than the disc surface. Therefore, it is necessary to measure whether the height difference between the disc surface and the end face of the tenon meets the customer's requirements. Since the detection location is a narrow and slender space, and the detection point is relatively special, the current detection method is to use a caliper to detect, a feeler gauge to remove the plug, or to observe with the naked eye. And it takes a long time to detect a product. In recent years, with the increa...
