Description

Technical Field

[0001] The present application relates to the technical field of automobile detection equipment, and more specifically, to an automobile transmission shaft outer diameter detection device. Background Art

[0002] The automobile drive shaft is the shaft that can transmit power in the universal transmission device. It is a high-speed, low-support rotating body and an important core component in the automobile transmission system. The outer diameter size of this component is very strict during production and assembly. If you are not careful, defective products may easily flow into the market, resulting in failure to assemble or unqualified assembly. Therefore, the outer diameter size detection of the drive shaft is a very important step in the drive shaft detection process.

The application sets a mounting sleeve and a movable rod, and the mounting sleeve and the movable rod are provided with card blocks on both sides of the top... The groove bottom is provided with a rubber damping pad, so that the position of the annular block remains fixed after the detection is completed, thereby facilitating the detection personnel to record data. However, the application is relatively cumbersome when it is necessary to detect the outer diameters of multiple parts of the transmission shaft with different outer diameters at different parts. After the outer diameter detection of one part is completed, the transmission shaft is removed and another part of the transmission shaft with a different diameter is re-installed between the two card blocks for detection.

The scale line value of the clamping plate close to motor two is observed, and the value is multiplied by two to obtain the measured value of the outer diameter of the drive shaft. Motor one is controlled to drive the threaded rod to rotate, and the rotation of the threaded rod causes the sliding block to move inside the sliding groove, so that the relative position of the detection component at different parts of the outside of the drive shaft can be adjusted, thereby facilitating the detection of the outer diameters of different parts of the drive shaft.
