A Checking Tool Used for Dimensional Inspection of Knuckle Arm

Abstract

The invention discloses a gauge for inspecting connecting lever sizes. The gauge comprises a base (5) and a base bolt (6) which is used for supporting the base (5), wherein three cylindrical pins, a block (2) and a spline shaft (3) are arranged on the base (5), the three cylindrical pins, the block (2) and the spline shaft (3) are used for inspecting a connecting lever to be inspected, distances among the three cylindrical pins, the block (2) and the spline shaft (3) are determined in accordance with the size of the connecting lever to be inspected, the diameter of a first cylindrical pin (1) is different from the diameter of a second cylindrical pin (4), and the diameter of the first cylindrical pin (1) is the same as the diameter of a third second cylindrical pin (7). By the aid of the gauge with the above structure, various connecting lever part hole center distances and eccentric angles can be inspected accurately, the measurement is simple and rapid, simultaneously, the problems that the inspection speed is low and personal errors exist are solved and the operation is convenient.

Description

technical field [0001] The invention relates to a checking tool for checking the size of a crank arm. Background technique [0002] In the prior art, processing enterprises generally use vernier calipers to detect the center distance of the crank arm parts, and use a projector to detect the eccentricity angle, and rely on the knowledge and skills of the inspectors, that is, experience. The method not only has a large workload and low work efficiency, but also has large measurement errors, which is not conducive to the follow-up work. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a checking tool for the size inspection of the crank arm in view of the problems existing in the prior art. efficiency. [0004] The technical solution of the present invention is that the inspection tool for the inspection of the crank arm size includes a base and a base nut supporting the base, and the base is provided with at least...
