Abstract

The invention relates to a T-shaped hole coaxiality detection method. The method comprises steps: (1) a first horizontal detection shaft and a second horizontal detection shaft are arranged on a base, the first detection shaft and the second detection shaft are coaxial, the first detection shaft is matched with a hole with a small diameter in the T-shaped hole and can move horizontally relative to the base, and the second detection shaft is matched with a hole with a large diameter in the T-shaped hole and can move longitudinally relative to the base; (2) the large hole end of a workpiece with a T-shaped hole sleeves the second detection shaft, the first detection shaft is driven to move horizontally, and the first detection shaft extends in the small hole of the workpiece; and (3) after the first detection shaft and the second detection shaft are contacted, the longitudinal movement displacement of the second detection shaft is measured, and the T-shaped hole coaxiality in the workpiece is obtained. The detection method of the invention is simple and easy to operate, the detection cost is low, and the measurement result is accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a method for detecting the coaxiality of a T-shaped hole. Background technique [0002] Coaxiality refers to the degree to which the axis of the measured cylindrical surface is not coaxial with the reference axis. Coaxiality detection is a problem often encountered in machining measurement. The current method of detecting coaxiality is to use two dial gauges and a gyroscope to perform detection according to the following steps: [0003] 1. Fix the reference axis on the gyroscope; [0004] 2. Adjust the reference axis so that it is concentric with the gyroscope; [0005] 3. Two dial gauges are fixed by the dial base and placed on both sides of the diameter of the measured shaft; [0006] 4. Adjust the position of the dial indicator so that it is in contact with the surface of the measured shaft; [0007] 5. Make the indications of the two dial gauges 0; [0008]...
