External gear cross-bar distance detection device

Abstract

The invention discloses an external gear cross-bar distance detection device which is composed of a pedestal, a meter head set, a fixed measuring head set and a side positioning base. As for the meter head set, the gear deviation is reflected to an indicating gauge from the measuring head through a spring and a flexible measuring rod. The side positioning base realizes fast positioning of the detected component. The fixed measuring head set is composed of a tail measuring head base and a tail measuring head. The pedestal is provided with three T-shaped grooves. Positioning bosses are arranged below the meter head set, the fixed measuring head set and the side positioning base to the matched with the neck of the T-shaped grooves of the pedestal so as to ensure accurate positioning, and the meter head set, the fixed measuring head set and the side positioning base are locked on the pedestal through bolts and slide blocks. The external gear cross-bar distance detection device has the advantages of being simple in measurement reading, high in batch measurement efficiency, low in technical requirement for measurement personnel, convenient to operate, accurate in measurement, convenient to adjust in product transformation and wide in application.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for the span of external teeth. Background technique [0002] At present, in gear production, external gears usually measure the common normal line by using a common normal line micrometer or use an outer diameter micrometer and a measuring rod to measure the cross rod distance, but in the mass production of finished product inspection, use an outer diameter micrometer or use a common normal line micrometer. The measurement efficiency is low, and at the same time, the technical level of the surveyor is required to be high. Therefore, it is necessary to design an external gear spanning rod distance detection device suitable for batch detection, which can quickly detect whether the gear spanning rod distance is qualified. Contents of the invention [0003] The invention provides a detection device for the cross-rod distance of external teeth, which can quickly measure whe...
