The utility model is provided with the steel balls arranged in a rolling way, thereby reducing the rolling resistance when rolling and closing in, and closing in processing can be carried out on the installation of bearings with different diameters, and the universality is stronger; the rolling allowance can be adjusted according to the actual rolling condition when the rolling device is matched with a machine tool for use, so that the problem of deformation and/or damage to a bearing and/or a part caused by uncontrollable stamping force in the traditional stamping mode is solved; simple structure, low cost, convenient operation and use and simple preparation method.

Description

Joint bearing mounting and closing tool based on rolling method

Technical Field

The utility model relates to a bearing installation tool, especially a joint bearing installation binding off instrument based on roll extrusion method.

Background

Generally, when the knuckle bearing is installed in an inner hole of a part, an opening of the part installation hole needs to be tightened so as to prevent the bearing from falling off in the using process.

In the prior art, the orifice of the mounting hole is tightened by using a stamping closing-in mode, and due to the fact that the instant impact force is large in the stamping closing-in process, the problem that parts and/or bearings are deformed and/or damaged is easily caused in the orifice tightening mode, installation failure is caused, the working efficiency is reduced, and meanwhile the production cost is increased.

SUMMERY OF THE UTILITY MODEL

For solving the problem that exists among the background art, the utility model provides a joint bearing installation binding off instrument based on roll extrusion method.

The purpose is achieved, the utility model adopts the following technical proposal: a joint bearing mounting and necking tool based on a rolling method comprises a cutter bar, a retainer and steel balls; the utility model discloses a cutter arbor, including cutter arbor, fixed cover, retainer, circle centering hole, steel ball, integrated casting forming's installation boss is equipped with to the use end of cutter arbor, the fixed cover can be dismantled in the outside of installation boss is equipped with the retainer, the terminal surface of retainer is equipped with the circle centering hole, the roll is equipped with the steel ball in the circle centering hole.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model is provided with the steel balls arranged in a rolling way, thereby reducing the rolling resistance when rolling and closing in, and closing in processing can be carried out on the installation of bearings with different diameters, and the universality is stronger;

2. the utility model is used in cooperation with a machine tool, can adjust the rolling allowance according to the actual rolling condition, and avoids the problem of deformation and/or damage to the bearing and/or the part caused by uncontrollable stamping force in the traditional stamping mode;

3. the utility model has simple structure, low cost, convenient operation and use and simple preparation method.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

A joint bearing mounting and necking tool based on a rolling method comprises a cutter bar 1, a retainer 4 and steel balls 5; the utility model discloses a cutter arbor 1, including cutter arbor 1, bolt 6, fixed cover, circle fixed hole 401, the roll is equipped with steel ball 5 in circle fixed hole 401, the use end of cutter arbor 1 is equipped with rather than coaxial setting and integrated casting shaping's installation boss 101, the outside of installation boss 101 can be dismantled through bolt 6 and fixed cover is equipped with tubbiness holder 4, the terminal surface of holder 4 runs through its thickness direction.

And a gasket 3 is arranged between the retainer 4 and the mounting boss 101, the ball 5 is circled on a horizontal plane 25mm away from the using end surface of the cutter bar 1, and the ball 5, the retainer 4 and the gasket 3 can rotate relatively.

The circle fixed hole 401 is a taper hole and is matched with the installation requirement of the steel ball 5.

The retainer 4 is positioned with the cutter bar 1 through the cylindrical pin 2, and the cylindrical pin 2 can fix the angular orientation of the ball 5 in the retainer 4, so that the ball 5 is parallel to the plane where the center of the retainer 4 is located and the bottom surface of the cutter bar 1.

The cutter bar 1 is a 25 multiplied by 25 square cutter handle, can be suitable for a numerical control lathe and a common lathe, and can finely adjust the rolling allowance according to the adjustment precision of the lathe.

The utility model discloses be connected with the lathe sword tower, adjust the position at sword tower relative part center according to part slot diameter. In the using process, the steel balls 5 can slowly roll the V-shaped grooves around the mounting hole of the part to enable the V-shaped grooves to generate plastic deformation, so that the mounting hole is slowly tightened and attached to the outer wall of the knuckle bearing. The rolling allowance can be adjusted according to the actual rolling condition by matching with a machine tool.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
