The invention relates to a brake block lining plate physical dimension measuring and sorting device, in particular to a device of online physical dimension measurement and sorting to a vehicle brake block lining plate through a high resolution camera. The device mainly aims at the problems of low product measurement automaticity, low efficiency, high labor intensity and the like lying in existingproduct manufacture. The device transfers the products to a to-be-inspected position, under the orderly cooperation of a dowel plate, a rectangle light source, a compression bar and an ejecting air cylinder, the operation of measurement and sorting of a key fit dimension and a whole physical dimension of the products can be automatically completed through a camera of fine shooting and all shooting. The device has the advantages of compact physical design, concise working process, easily realized mechanism movement, and high work efficiency and reliability.
