Abstract

The invention relates to an apparatus for measuring an end surface of a screw rod. The apparatus comprises an apparatus body; a first groove for detecting a workpiece is formed in the upper part of the apparatus body; a second groove for detecting a workpiece is formed in the lower part of the apparatus body; and the orientations of the first groove and the second groove are consistent. Rotatable not-go-end wheels are arranged at the groove walls at two sides of an opening end of the first groove; and rotatable go-end wheels are arranged at the groove walls at two sides of an opening end of the second groove. A telescopic shaft is arranged at the center of the apparatus body and can stretch out or draw back to adjust the space between two split bodies of the apparatus body; and a scale groove is formed in the telescopic shaft. Compared with the prior art, the measuring apparatus has the following advantages: the measurement precision can be guaranteed; rapid measurement can be realized; because the telescopic shaft is adjusted based on the dimension of the detected workpiece, so that adaptability to different workpieces is high; and with the scale groove, the dimension can be obtained directly.

Description

Technical field [0001] The invention relates to the technical application field of measuring tools, in particular to a device for measuring screw end faces. Background technique [0002] Automobile recirculating ball steering gear is currently one of the most widely used structural types at home and abroad. The quality of the R arc on the end of the steering screw directly affects the performance and service life of the steering gear assembly. Since the R arc is located on the end surface of the steering screw, the dimensional accuracy is required to be high, and it is not easy to measure. The measurement method is time-consuming and labor-intensive, which is not conducive to mass processing of products. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a measuring screw end face device that can not only ensure the measurement accuracy, but also realize rapid measurement. [0004] The technical solution of the present invent...
