Description
Technical field
The invention belongs to the component assembling apparatus of ball screw.
Background technology
Ball screw spiral pair is a kind of Novel spiral transmission mechanism, has between spiral fluted leading screw and nut and intermediate transmission element-ball is housed.Ball-screw screw thread pair it be made up of leading screw, nut, steel ball, reverser four part.When screw turns, drive ball threadingly rolling path rolling, for preventing steel ball from dropping out from raceway end face, being provided with the circulation backward channel that steel ball backhaul guiding device forms steel ball at the helicla flute two ends of nut, thus forming the closed road of steel ball flowing.
Ball screw nut is a very accurate product, if just there will be the failure of steel ball arranged in dislocation a little because of carelessness when mounted, general step of installing steel ball is: 1, ball-screw nut with to roll the clean kerosene of steel ball clean clean; 2, reverser is put back in nut.To notice when block bead device is installed that block bead device ball is imported and exported will link up smoothly with helicla flute.3, lithium base grease is coated with in nut, in order that fix steel ball by the bonding force of grease.4, ball is put into helicla flute.5, nut is screwed into rotating nut forward-reverse in leading screw, checks whether nut runs smooth and easy, as smooth and easy this represents installation.
The shortcoming of such scheme is: the steel ball box of factory is piled up on the table, steel ball box often opens wide again in order to easy to use, dust easily enters in steel ball box, steel ball specification is many in addition, and workman easily selects wrong steel ball specification, cause the steel ball of different size to load in mixture on screw mandrel, cause screw mandrel to detect defective.
Summary of the invention
The invention is intended to provide a kind of can dust-proofly can prevent again the steel ball of different size from loading in mixture ball screw screw thread pair steel ball apolegamy platform.
Object of the present invention can be reached by following measures: ball screw screw thread pair steel ball apolegamy platform, comprise the positioning disk that cross section is inverted T-shape, this positioning disk is made up of the mandrel on the pedestal of bottom and pedestal, mandrel upper end is fixed with index dial by housing screw, mandrel axle body to be rotatably assorted rolling disc by bearing, between rolling disc and index dial, to be provided with the detent mechanism controlling turn disc angle; Rolling disc side is fixed with some independently fan-shaped steel ball boxes, and the central angle of fan-shaped steel ball box is identical with rolling disc single revolution angle, is provided with the handle being marked with steel ball specification bottom fan-shaped steel ball box; Described index dial perisporium is provided with the dust cap covering fan-shaped steel ball box, this dust cap has overlap with fan-shaped steel ball box shaped uncovered, uncovered edge is hinged with removable cover.
Technique scheme difference with the prior art is: some independently fan-shaped steel ball boxes are respectively charged into the steel ball of different size, handle is marked with steel ball specification, when stirring handle, fan-shaped steel ball tape moves rolling disc and rotates around mandrel, because index dial is fixedly connected with mandrel, during turn disc, index dial keeps static, detent mechanism can control the rotational angle of rolling disc, the central angle of fan-shaped steel ball box is identical with rolling disc single revolution angle, stir the distance that turn disc once then rotates a fan-shaped steel ball box, namely be dust cap uncovered under fan-shaped steel ball box be switched to the fan-shaped steel ball box of another steel ball specification, so, workman just can very clearly differentiate steel ball specification when using different steel ball, leading screw is there will not be to load in mixture phenomenon.In addition, the design of dust cap can prevent dust from entering in fan-shaped steel ball box, with the removable cover opened during steel ball on corresponding fan-shaped steel ball box, does not affect the cleanliness factor of the fan-shaped box of state of non-usage.
Further, described detent mechanism comprises some locating slots and a locating dowel, some locating slots are discrete to be equably distributed on the same circumference of index dial bottom surface, locating dowel is positioned at the locating hole of rolling disc upper end, this locating dowel upper end is the round end mated with locating slot, the shaft of locating dowel is contacted with at the bottom of locating hole hole by spring, and during turn disc, the movement locus of locating dowel overlaps with locating slot place circumference.During turn disc, when locating dowel contacts with index dial base plane district, the spring in locating dowel is compressive state, when locating dowel moves to the locating slot bottom index dial, spring-return in locating dowel drives locating dowel to move, and round end and the locating slot of locating dowel block, and complete location.
Further, pressing plate is provided with between the nut of described housing screw and index dial, this pressing plate and dust cap one-body molded, housing screw applies the thrust of local to pressing plate, thrust is applied in index dial card by pressing plate equably, index dial and rolling disc upper end are kept in touch, avoids because the situation that gap causes detent mechanism invalid appears in index dial and rolling disc upper end.
Further, described fan-shaped steel ball box be by screw and rolling disc fastening, ensure rolling disc and fan-shaped steel ball box synchronous axial system.
