Device for rapidly detecting inner circle surface and thickness of connecting rod

Abstract

The invention relates to the technical field of engine connecting rod rapid measurement, and in particular, relates to a device for rapidly detecting the inner circle surface and thickness of a connecting rod, wherein the device comprises a working table top, an end part pressing mechanism, non-contact sensors, upper layer sensors and a lower layer sensor; the end part pressing mechanism is used for fixing a big head of the connecting rod; the non-contact sensors are arranged at the positions, corresponding to the two inner circles of the connecting rod, of the working table top, the non-contact sensors rotate in the inner circles of the connecting rod, the upper layer sensors are arranged on the non-contact sensors, a lever measuring head is arranged on each upper layer sensor, and the lower layer sensor is arranged on the working table top; and the lower layer sensor is located below the small end of the connecting rod. According to the method, more key point data can be collected, more parameters can be used for evaluating the parallelism of the inner circle surface and the two holes, the actual production rhythm can be quickly responded, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of rapid measurement of engine connecting rods, in particular to a rapid detection device for the inner circular surface and thickness of a connecting rod. Background technique [0002] In the mass production of existing connecting rods, quality control generally adopts regular sampling inspection or traditional offline inspection. The sampling inspection method adopts three-coordinate equipment measurement. Considering the existence of vibration, oil stains and dust in the process of connecting rod processing, the workpiece needs to be cleaned before sampling and delivery for precise measurement, which is inefficient. The off-line measurement methods include: Type 1, the contact sensor is evenly distributed at three to four points on the circumference; Type 2, the sensor is attached to the inner wall of the circular hole to make a 360-degree rotary motion. In the above two methods, the sensor needs to be i...
