The invention provides a device for measuring the height of the center of an inner star wheel fairway. The device comprises a measuring frame and a length error measuring tool vertically arranged on the measuring frame. The bottom end of the length error measuring tool is connected with a measuring base plate, a positioning plate used for positioning an inner star wheel is arranged under the length error measuring tool, and at least three positioning balls are evenly fixed on the periphery of the positioning plate. When the device is used, the inner star wheel to be measured is matched with the positioning balls through an arc-shaped section of the inner star wheel fairway and is supported on the positioning plate, the length error measuring tool is adjusted to enable the measuring base plate to be attached to the upper surface of the inner star wheel to be measured. The length error measuring tool is provided with a dial indicator or a micrometer gauge. The device for measuring the height of the center of the inner star wheel fairway has the advantages of being simple in structure and convenient to measure and improving measuring rate.
Description
technical field [0001] The invention relates to a measuring tool, in particular to a measuring device for the center height of an inner star wheel fairway. Background technique [0002] As the key parts of the constant velocity universal joint, the ball cage and inner star wheel are divided into RE, AC, UF, VL and other parts according to their joint types. The dimensional accuracy of the center height is very high, which directly affects the performance of the assembly. [0003] The measurement of the center height of the inner star wheel fairway is usually carried out in Helios, and a special fixture is required for the measurement. If there is no special fixture, the three-coordinate measurement will be used, which will cause a long downtime of the machine tool on site, and is not conducive to the quality control of the process. . In the past, the center height of the inner star wheel fairway was measured by using the German ZEISS three-coordinate measuring instrument. ...
