Description

A kind of bearing bead loading module

Technical field:

The utility model relates to a kind of bearing bead loading module in order to the running in bearings ball.

Background technique:

At present, in bearing ball assembling field, particularly in the assembly process of miniature bearing ball, what generally adopt is the method for hand assembled, and ball assembles into back positioning easily, brings certain influence for follow-up bearing ball bulb separation technology, is unfavorable for the realization of automation process.So a kind of new and bearing ball assembling module that have comparatively simple structure to be excavated is arranged, to satisfy the demand of production and automation process.

Summary of the invention:

The purpose of this utility model is that design is a kind of can be to the bearing ball bead loading module of not positioning after the bearing ball assembling.

Technical solutions of the utility model are achieved in that a kind of bearing bead loading module, its structure includes dynamically station pearl mould of a bearing positioning seat and, support platform, the platform that positioning seat has a spring bearing Internal and external cycle be provided with one with the bearing inner race coupling can the positioning bearing inner ring boss, dynamically station pearl mould leans against a side of positioning seat, be convexly equipped with on it one with the arc station Zhu Tai of boss concentric, the Zhu Tai two ends of standing are provided with the block bead salient point, and this station Zhu Tai and block bead salient point can insert between the bearing enclose.This module both had been fit to artificial bead loading operation, also was suitable for automation bead loading operation.At first on positioning seat, place bearing enclose, and make bearing outer ring be offset to station pearl mould one side; The quantitative ball of packing in the bearing enclose crescent-shaped land, ball are between Internal and external cycle and the station pearl mould three; The bearing outer ring that drives biasing is until the conflict ball, and at this moment, all balls are stressed, and Zhu Tai is that step is rolled in the raceway groove of bearing enclose with the station, and closely is limited in being beneficial to down the road and dividing the pearl operation between the two block bead salient points.

The thickness of described station Zhu Tai is not more than the bearing enclose design at interval, and both convenient station pearl mould breaks away from, and does not also influence the concentric operation of bearing enclose.

Described station Zhu Tai highly is bearing thickness and bearing ball difference in diameter 1/2 times.

Arc length between the pearl platform two block bead salient points of described station is not less than the summation of design bearing ball number diameter, satisfies the need of the tight arc shooting of quantitative ball, and pearl facilitated for follow-up minute.

The utlity model has reasonable in design, simple in structure, the accurate characteristics of bead loading working specification, the ball that can guarantee at every turn to fall into both determined number of bearing enclose has definite position and height, for the assembly technology in later stage and the process of automation assembling are prepared.

Embodiment:

With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of bearing bead loading module, it includes dynamically station pearl mould 2 of a bearing positioning seat 1 and, the positioning seat top is provided with pearl mould 5 every place, a bearing position, positioning seat 1 has the support platform 11 and a boss 12 of a spring bearing Internal and external cycle, this boss external diameter is slightly less than bearing inner race 31 internal diameters, and bearing inner race 31 can pack into boss 12 location, and the plane of support platform 11 provides bearing outer ring 3 to move and adjusts concentric need.Dynamically station pearl mould 2 leans against a side of positioning seat 1, can move up and down, and is beneficial to down the need that the road divides pearl; Stand be convexly equipped with on the pearl mould 2 one with the arc station pearl platform 21 of boss 12 concentrics, the design that the thickness of the pearl platform 21 of stand is not more than bearing inner race 31, outer ring 3 avoids influencing the concentric adjustment operation of bearing inner race 31, outer ring 3 and the action of the pearl mould 2 descending demouldings of standing at interval; Station pearl platform 21 arc length that pearl platform 21 two ends are provided with 22 of block bead salient point 22, two block bead salient points of standing are slightly larger than the summation of design bearing ball number diameter, also promptly can hold both balls 4 of determined number on this station pearl platform 21.The effect of block bead salient point 22 is to guarantee that ball relatively closely sorts to stand on the pearl platform 21, is beneficial to down the need that the road divides pearl.

The Zhu Tai that stands highly is bearing thickness and bearing ball difference in diameter 1/2 times.When making ball 4 be rolled to station pearl platform, be in just in the raceway groove of bearing enclose.

With reference to Fig. 2, Fig. 3 and Fig. 5, no matter be artificial bead loading or automation bead loading, all configurable mould of pearl once 5, this time pearl mould 5 has the hole of bead 51, and hole, following hole of bead beak 52 can insert bearing

inner race

31,3 gaps, outer ring, so that accurately descend pearl.The crescent shape structures that are complementary after 52 one-tenth on hole beak and bearing inner race 31, outer ring 3 biasings also can guarantee in the bead loading process, and bearing inner race 31, outer ring 3 are relatively stable.Following pearl mould 5 may operate at positioning seat 1 top and locates every a bearing position, drives lifting and mobile by artificial or automation equipment.

Fig. 2, generalized section during for bead loading, at this moment, bearing inner race 31, outer ring 3 are biasing, artificial or the automatic equipment driving mode of following pearl mould 5 drops to the bearing top, and its hole beak 52 inserts bearing inner races 31, the 3 eccentric crescent moon spaces that form, outer ring, and ball 4 is under deadweight or external force effect, fall into the bearing enclose gap, and cushioned by station pearl platform 21.

Fig. 3, be bearing enclose adjustment generalized section when concentric, after following pearl is finished, remove down pearl mould 5, and artificial or automatic equipment driving lower bearing outer ring 3 mobile adjusting on platform 11, until concentric with bearing inner race 31, at this moment, both the ball 4 of determined number was adjusted in the raceway groove of bearing enclose 31,3 just, under the restriction of two block bead salient points 22, both the ball of determined number was closely arranged for 4 one-tenth, as Fig. 4 structure, for follow-up bearing assembly technology is that automatic production provides the important position reference factor.

Above-mentioned only is one of the utility model preferred embodiment, and for this reason, all equivalent variations of doing according to technical solutions of the utility model all should belong in this patent covering scope.
