Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
A cold riveting tool for a tapered roller bearing retainer is fixedly connected to a workbench of a spin riveting machine and comprises a bearing inner ring supporting seat 1 with an adjustable inclination angle and a top column 2 used for bearing riveting pressure, wherein the top column 2 is coaxially arranged with a rotary riveting head of the spin riveting machine. The ejection pin is arranged on the ejection column 2 and used for bearing the lower end face of the roller shaft and bearing the downward pressure of the rotary riveting head.
Bearing inner race supporting seat 1 includes horizontal fixed plate 1.1 and with horizontal fixed plate 1.1 articulated hang plate 1.2, hang plate 1.2 can follow the pivot rotation on the horizontal fixed plate 1.1. The inclined plate 1.2 is provided with a jackscrew 1.3 for adjusting the inclination angle. In order to facilitate adjustment, a ball head is arranged at one end of the jackscrew 1.3, which is in contact with the horizontal fixing plate 1.1.
Two T-shaped grooves are further arranged on the inclined plate 1.2, and each T-shaped groove comprises a transverse T-shaped groove and a vertical T-shaped groove which are perpendicular to each other. Three positioning columns 1.4 are connected in the T-shaped groove in a sliding mode, in the embodiment, the positioning columns 1.4 are inner hexagonal screws, the inner hexagonal screws are in threaded connection with T-shaped sliding blocks in the T-shaped groove, and the inner hexagonal screws can be fastened at any position of the T-shaped groove. The three inner hexagonal screws are arranged in a non-collinear way, and after the three inner hexagonal screws are fixed, screw heads of the three inner hexagonal screws are tangent to the inner ring surface of the bearing inner ring, so that the bearing inner ring can be positioned.
When the conical roller bearing adjusting device works, firstly, the included angle between the horizontal fixing plate 1.1 and the horizontal fixing plate 1.1 is adjusted through the jackscrew 1.3 by means of an angle instrument according to the inclination angle of the conical roller bearing, so that the included angle is the same as the inclination angle of the conical roller bearing. Then, the bearing inner ring, the roller group, the inner and outer retainers and the roller shafts are preassembled and then placed on the inclined plate 1.2. Because the height of the top column 2 is fixed, the preassembled bearing inner ring needs to move back and forth along the inclined plate 1.2, the lower end face of one roller shaft is just aligned and contacted with the thimble on the top column 2, at the moment, the three inner hexagonal screws are adjusted, the screw heads of the three inner hexagonal screws are tangent to the inner ring face of the bearing inner ring, and finally, the three inner hexagonal screws are fastened, so that the bearing inner ring is positioned and riveted. Because the bearing inner ring is positioned, when riveting, only the roller group needs to be rotated, and the lower end face of the next roller shaft is positioned on the supporting plane of the thimble of the top column 2.
The utility model discloses still be suitable for the riveting of the tapered roller bearing of different specifications, when bearing diameter size changes, only need adjust the position of hexagonal screw in three, alright make the bearing inner race location to make the lower terminal surface of roller shaft be in on the support plane of 2 thimbles of fore-set. The utility model discloses still can satisfy different tapered roller bearing's inclination through adjustment horizontal fixed plate 1.1 and horizontal fixed plate 1.1's contained angle.
Compared with the prior art, the utility model is simple in operation, efficient, intensity of labour is little, and is applicable to the cold riveting of the tapered roller bearing roller shaft of different specifications, different inclination and holder.
The part of the utility model not detailed is prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
