Self-centering rotary detection table

Abstract

The invention discloses a self-centering rotary detection table which comprises a gauge stand, an opening gland, a tensioning column, a tensioning cover and a chassis, wherein the tensioning column is rotationally arranged in the middle of the chassis and has a conical structure; the tensioning cover is arranged outside the tensioning column in a sleeving manner and has a cylindrical cavity structure; the cavity is conical and is matched with the appearance of the tensioning column; the opening gland is arranged on the top of the tensioning cover and is in threaded connection with the tensioning column by virtue of a tightening screw; the gauge stand is arranged on the chassis in a sliding manner; and a gauge head is arranged on the gauge stand. The self-centering rotary detection table disclosed by the invention is flexible to use, and the detection efficiency and accuracy of each location degree of the wheel are greatly improved; the detection table is convenient to manufacture, low in cost and high in utilization rate and can be matched with multiple common check measuring tools; and complicated detection is simplified, multiple sizes and form and location tolerances needing to be detected in a rotating state are unified together, one-time detection is realized, and the result is obtained.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a self-centering rotating testing platform. Background technique [0002] In the construction machinery industry, supporting rollers and supporting rollers are required for the traveling mechanisms of excavators, bulldozers, drilling machines, crawler cranes and other equipment. The liquid pressurized oil is sealed inside the rollers and supporting rollers, which are vulnerable parts. Track rollers and supporting wheels are limited by the service life of the seals, and the general warranty period is one year or 2000 hours of work. There are generally more than a dozen parts that make up the rollers and the supporting wheels, the most important parts of which are the wheel body, the shaft and the end cover, and they are also called the three major parts of the supporting wheel. [0003] Among the three major parts, the wheel body has the most processing procedures, and...

Problems solved by technology

There are tolerances in the machining of the inner hole of the wheel. It is impossible for all the inner holes of the machined wheel to have the same size, so it is difficult to perfectly match the mandrel.

If the inner hole of the wheel is larger than the mandrel, although the wheel body can rotate flexibly, there will be a gap between the mandrel and the wheel body, which will cause errors during inspection

If the inner hole of the wheel is smaller than or equal to the mandrel, the wheel body may not be able to be put into the mandrel. Even if it can be put in, it will cause the wheel body to rotate inflexibly, or even cannot rotate, making it difficult to check the concentricity and reduce the inspection efficiency. Moreover, each wheel body of different sizes must be equipped with a mandrel, which is very troublesome to make
