Reverse assembly detection device and detection method for conical roller bearing inner ring assembly

Abstract

The invention discloses a reverse assembly detection device and a reverse assembly detection method for a conical roller bearing inner ring assembly. The reverse assembly detection device comprises a base, a columnar core shaft with an annular step, and one or two groups of adjusting stop block and bolt combinations; the columnar core shaft comprises an upper small core shaft, a lower large core shaft and the middle annular step; the lower end of the columnar core shaft is fixedly connected with the base, and the columnar core shaft and the base are mutually vertically arranged; and the adjusting stop block is positioned on one side of the columnar core shaft with the step and connected with the base by bolts in a proper distance. The small end of a product to be detected is put on the annular step of the columnar core shaft, and an operator rotates the product by hand; if the product can rotate in a whole ring, the assembly of the product is normal; if the product collides with the large end of the conical roller and is blocked by the adjusting stop block so as not to rotate in the whole ring, the conical roller is reversely assembled. The reverse assembly detection device has the advantages of simple structure, convenient debugging and operation, strong practicability and high detection efficiency, ensures full reliable detection, and ensures the quality of the product.

Description

technical field [0001] The invention relates to a detection device and a detection method for an inner ring assembly of a tapered roller bearing, in particular to a reverse assembly detection device and a detection method for an inner ring assembly of a tapered roller bearing. Background technique [0002] The tapered roller bearing inner ring assembly consists of a tapered inner ring, a cage and tapered rollers, as shown in Figure 3(A) and (B). During the assembly process of the conical inner ring assembly, due to factors such as machine tooling or workers, it is inevitable that the tapered roller may be reversed, that is, the large end and the small end of the tapered roller are reversed, as shown in Figure 4 (A ), (B) shown. Therefore, after the tapered roller bearing inner ring assembly is assembled, there must be an inspection process, and all the reverse-assembled tapered roller bearing inner ring assemblies must be checked out. [0003] At present, the detection met...

AI Technical Summary

Problems solved by technology

However, it is easy to miss inspection if the tapered roller is installed backwards by naked eyes.

Because in the manual rotation of the tapered roller bearing inner ring assembly, the rotation may not be complete; or the operation at night, the light is not good, or due to long-term visual inspection, the operator's visual fatigue is caused, or some situation occurs around the Any negligence may cause missed inspections, which will seriously affect product quality.

Once such a situation occurs, the resulting quality accidents are often fatal, which not only affects the reputation of the company, but may also cause irreparable losses to customers.
