Problems solved by technology
The traditional comprehensive detection method is a four-point measurement method, which is positioned by two guide sleeves, and three cross-sectional measuring points are arranged on the circumference of the guide sleeve. Each cross-section has four fixed measuring points, and each measuring point corresponds to a Sensor, put the connecting rod into two guide sleeves for measurement, but this detection method has the disadvantages of few sampling points, high cost, and difficult to guarantee accuracy, and some processing defects cannot be reflected in time and accurately, which increases the occurrence of quality problems. risk

The invention discloses a rotating measuring mechanism, which comprises a mounting frame, a rotating motor installed on the bottom plate of the mounting frame, an air bearing connected with the rotating motor through a coupling, a measuring rod mechanism slidably installed on the air bearing, and The slip ring is coaxially installed between the coupling and the air bearing. The signal line of the measuring rod mechanism passes through the through hole in the rotor center of the air bearing inner ring of the air bearing and is connected to the lead wire of the inner ring rotor of the slip ring. , the rotating motor drives the sensor on the measuring installation rod for 360-degree detection, so as to realize the circumference detection of the inner holes of different diameters of the connecting rod; a scanning connecting rod measuring instrument using the rotating measuring mechanism is also provided, so that each inner hole of the connecting rod A sensor is arranged on each, and the rotating motor drives the sensor on the measuring installation rod for 360-degree detection, so as to realize the circumference detection of the inner hole of the connecting rod.
Description
technical field [0001] The invention relates to the technical field of engine connecting rod measurement, in particular to a rotating measuring mechanism and a scanning connecting rod measuring instrument. Background technique [0002] In the vehicle engine, the connecting rod is used to connect the crankshaft and the piston. Therefore, the connecting rod plays a very critical role in the operation of the engine. In the mass production process, the quality control of the connecting rod is particularly important. The traditional comprehensive detection method is a four-point measurement method, which is positioned by two guide sleeves, and three cross-sectional measuring points are arranged on the circumference of the guide sleeve. Each cross-section has four fixed measuring points, and each measuring point corresponds to a Sensor, put the connecting rod into two guide sleeves for measurement, but this detection method has the disadvantages of few sampling points, high cost, ...
