Shaft part finished product quality detection method

Abstract

The invention discloses a shaft part finished product quality detection method which comprises the following steps: step 1, part fixation: placing a shaft in a V-shaped groove at the top of a fixed seat, limiting the shaft, pushing a fixing cylinder by a reset spring to extend out of a test piece, and pressing a jacking ball on the surface of the fixing cylinder against the surface of a part; step2, size detection, wherein a driving motor is started to drive a sliding base to slide along a sliding rod and drive an annular rail to move, the annular rail drives a sliding piece to move when moving, at the moment, the jacking ball rolls along the surface of the part, and the surface size is changed. According to the shaft part finished product quality detection method, the jacking ball abutsagainst the surface of the part, when the size of the surface changes, the jacking ball moves, the moving distance is converted into resistance conversion through a resistance detection block, so thatthe size change can be rapidly detected. The method is rapid in detection, is simple in use and is precise in detection.

Description

technical field [0001] The invention relates to the technical field of quality inspection, in particular to a quality inspection method for finished shaft parts. Background technique [0002] With the gradual transfer of the global manufacturing center to my country, while the production and manufacturing capacity is continuously expanding, people have also put forward higher and higher requirements for product quality. Use or deep processing has an important impact. In some application areas, the existence of surface defects may cause huge losses to users, and strict inspection and control must be carried out. [0003] Shaft parts are one of the most common typical parts in machining. It mainly plays the role of supporting transmission parts and transmitting torque. Shaft parts are rotary parts, and the length is greater than the diameter. Large shaft parts are widely used in the field of machinery manufacturing. , such as the support roll of the rolling mill, the large sha...
