Measuring Method of Machining Stress of CNC Aeronautical Thin-walled Parts

Abstract

The invention discloses a method for detecting machining stress of a numerically controlled aviation thin-walled part. The method includes the following steps: S1. Installing the aviation thin-walled part on a fixing part, the fixing part includes a fixing seat, a support plate, a plurality of Clamping mechanism and multiple support mechanisms. S2. Use a vibration detector to detect the edge and the middle, and adjust the clamping mechanism and the support mechanism so that the vibration frequency of the vibration detector at any edge and middle is less than 5 Hz. S3. Install the stress detection part on the aviation thin-walled part. The stress detection part includes a pressure sensing component and multiple force detection mechanisms to detect the value of the force detection mechanism to obtain the stress of the aviation thin-walled part. The detection method has a novel structure, can quickly install and fix aviation thin-walled parts, and the structure of the stress detection part can be quickly adsorbed on the surface of aviation thin-walled parts, so as to achieve the purpose of quickly detecting aviation thin-walled parts .

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a method for detecting machining stress of numerically controlled aviation thin-walled parts. Background technique [0002] Parts need to be processed on the surface during processing, but after the processing is completed, they need to be inspected, and the inspection is used to detect the flatness stress of the surface. Flatness refers to the deviation of the macro-concave-convex height of the substrate from the ideal plane. The tolerance zone is the area between two parallel planes whose distance is the tolerance value. Flatness belongs to the shape error in the shape error. Parts are mass-produced on the production line, and in the existing technology, most of the flatness stress is detected by manual random inspection, which saves time and cost, but due to the stability of production equipment, it may cause a part or a certain period of time. The flatness of the parts i...

Problems solved by technology

Parts are mass-produced on the production line, and in the existing technology, most of the flatness stress is detected by manual random inspection, which saves time and cost, but due to the stability of production equipment, it may cause a part or a certain period of time. The flatness of the parts is unqualified, resulting in the outflow of unqualified parts, causing customer complaints and other accidents; some enterprises adopt the method of inspection one by one, which can avoid the outflow of unqualified parts, but the detection efficiency is low, and the production speed of the equipment is faster than the detection speed. It leads to the accumulation of parts and cannot be detected in time, resulting in the failure to find the defective parts in the production process in time, causing batches of defective products to be produced, causing a lot of damage to the enterprise
