Problems solved by technology

Turn the camshaft on which the cam to be tested is installed clockwise or counterclockwise, and observe the data fed back by the two encoders during the rotation of the cam to be tested from the zero position to the start position of the thrust and from the start position of the thrust to the zero position. Repeated detection, data collection, drawing the profile of the cam to be tested, and then analyzing whether the cam to be tested is qualified, the whole process is cumbersome and the detection efficiency is low

Abstract

The invention discloses a cam profile detection device. The cam profile detection device comprises a standard gauge block (2) for detecting a to-be-detected cam profile, and a detection hole (11) consistent with the to-be-detected cam profile is formed in the standard gauge block (1). By applying the cam profile detection device, due to the fact that a to-be-detected cam is placed into the standard gauge block (1), if the to-be-detected cam profile is completely matched with the profile of the detection hole in the standard gauge block (1), and it shows that the to-be-detected cam profile is qualified; if not, the to-be-detected cam profiled is not qualified. Accordingly, the to-be-detected cam profile can be rapidly and effectively judged, repeated reading calculation is avoided, the detection time is shortened, the labor intensity is lowered, and the detection efficiency of the cam profile is improved.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a cam profile detection device. Background technique [0002] The cam mechanism usually includes a cam, a follower and a frame, which has the advantages of simple structure, compactness, and reliable operation. Generally, the cam profile is designed according to the expected movement law of the follower. Therefore, the shape of the cam profile curve Determines the movement law of the follower. In order to ensure the accurate movement of the follower, it is particularly necessary to detect the cam profile. [0003] At present, the cam profile detection mainly relies on the cam profile detector. The cam profile detector includes a camshaft for installing the cam to be tested, a follower matched with the cam to be tested, and two encoder. Turn the camshaft on which the cam to be tested is installed clockwise or counterclockwise, and observe the data fed back by the two encod...
