Clamp for installing tapered roller bearing outer rings of axle hub

Abstract

The invention discloses a clamp for installing tapered roller bearing outer rings of an axle hub. The clamp comprises a lower pressure head part and an upper pressure head part, wherein the lower pressure head part comprises a base plate and a sliding seat; a counter table hole is formed in the middle of the sliding seat; lower ends of four guide columns are respectively and vertically connected with four corners of the sliding seat; a through hole corresponding to the counter table hole in the sliding seat is formed in the middle of a work piece supporting plate; guide sleeves are respectively arranged in holes at the four corners; the upper end of each guide column is matched with one guide sleeve; one first spring is arranged on each guide column in a sleeving manner; the clamp also comprises a sliding column; the upper end part of the sliding column is fixedly connected with a tapered lower pressure head; the lower end part of the sliding column is matched with a lower cover ring; a second spring is arranged at the lower part of the sliding column; the upper pressure head part comprises a connector and an inverted tapered upper pressure head; and the upper pressure head corresponds to the lower pressure head. The clamp can simultaneously install tapered roller bearing outer rings on two sides of the axle hub, so that the clamping frequency is reduced, the assembly time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a jig for assembling automobile parts, in particular to a jig for mounting the outer ring of a tapered roller bearing on a wheel hub of an axle. Background technique [0002] Tapered roller bearings are widely used in machinery and transportation equipment, such as the axle hubs of heavy vehicles, which need to be equipped with tapered roller bearings on both sides. When installing tapered roller bearings, the inner ring and outer ring are usually assembled separately, that is, the installation of a set of tapered roller bearings requires two types of fixtures to be operated twice. In the CN 2701593Y announcement "Indenter and Sleeve for Assembling Tapered Roller Bearings", when assembling the outer ring of the tapered roller bearing, the indenter and the press are used to cooperate; when assembling the inner ring of the tapered roller bearing, the sleeve is used. The method of matching the cylinder with the press or hitting...

AI Technical Summary

Problems solved by technology

Both sides of the axle hub need to be installed with tapered roller bearings, and the thrust directions of the tapered roller bearings installed on both sides of the axle hub are opposite. Therefore, using the existing assembly fixture, only two bearings with opposite thrust directions are assembled. Tapered roller bearing outer ring, it needs to be operated twice to complete

Since the weight of the axle hub of a heavy-duty vehicle is usually about 50Kg, it is not only laborious and labor-intensive to clamp, but also the assembly speed is slow, the production efficiency is low, and the production schedule is also affected.
