Abstract
This utility model relates to a kind of linear contact lay ball guide pillar guide pin bushing assembly in mould upper and lower mould stroke guide technical field, including guide pillars and bushes, it is arranged with ball retainer between described guide pillars and bushes, on described ball retainer, longitudinal direction circumferentially is embedded with some row balls, it is characterized in that, the inner circumferential that described guide pin bushing is corresponding to each row ball is correspondingly provided with the Inner arc chute that the cambered surface linear contact lay with ball of corresponding columns coordinates, the periphery that described guide pillar is corresponding to each row ball is correspondingly provided with the cylindrical chute coordinated with ball cambered surface linear contact lay of corresponding columns, described ball and the Inner arc chute of guide pin bushing, on the external arc chute of guide pillar and ball retainer, the hole of setting-in rolls and coordinates.Assembly of the present utility model, during guiding movement, coordinates the point cantact of ball with guide pillar guide pin bushing and changes linear contact lay cooperation into, hence it is evident that improve the rigidity of assembly；And ball is not easy to be deformed, vibrating minimum during work, precision is high, and operation stability is greatly improved.
Description
Technical field
This utility model relates to a kind of linear contact lay ball guide pillar guide pin bushing assembly in mould upper and lower mould stroke guide technical field.
Background technology
Guide pillar guide pin bushing group is for guiding mold stroke, it is ensured that mold stroke director element accurately.In prior art, using ball Guide column component as director element the most in a mold, its ball retainer is provided with ball, has the advantage that precision is high and use cost is low.But there is also some problems: owing between ball and guide pillars and bushes being a point cantact simultaneously, therefore rigidity is relatively low, although some rigidity can be improved by increasing precompressed amount, but impact when ball pours is bigger, vibration can be produced, and easily cause the abrasion between guide pillar and guide pin bushing, affect the precision of assembly, stability and life-span.Therefore, in the diel that some rigidity and required precision are higher, ball Guide column component, because the bad shortcoming of poor rigidity, stability have impact on the normal use of mould, reduces the mold use life-span.
Utility model content
The problems referred to above that this utility model exists for guide pillar guide pin bushing modular construction in prior art, it is provided that a kind of linear contact lay ball guide pillar guide pin bushing assembly, to reduce the vibratory impulse in transmission process, improve transmission accuracy and transmission stability.
The purpose of this utility model is realized in, a kind of linear contact lay ball guide pillar guide pin bushing assembly, including guide pillars and bushes, it is arranged with ball retainer between described guide pillars and bushes, on described ball retainer, longitudinal direction circumferentially is embedded with some row balls, it is characterized in that, the inner circumferential that described guide pin bushing is corresponding to each row ball is correspondingly provided with the Inner arc chute that the cambered surface linear contact lay with ball of corresponding columns coordinates, the periphery that described guide pillar is corresponding to each row ball is correspondingly provided with the cylindrical chute coordinated with ball cambered surface linear contact lay of corresponding columns, described ball and the Inner arc chute of guide pin bushing, on the external arc chute of guide pillar and ball retainer, the hole of setting-in rolls and coordinates.
Linear contact lay ball guide pillar guide pin bushing assembly of the present utility model, owing on ball retainer, the projecting surface of ball is respectively embedded in the arc chute of guide pillars and bushes, and arc chute cross section arc contacts cooperation and instead of original point cantact with the pearl face curved line of ball, the rigidity of linear contact lay ball guide pillar guide pin bushing assembly is made to be significantly larger than point cantact ball guide pillar guide pin bushing assembly；Simultaneously, the precompressed amount of linear contact lay guide pillar guide pin bushing assembly is significantly less than plain ball guide pillar guide pin bushing assembly, ball is not easy to be deformed, vibration operationally is minimum, precision is high, operation stability is greatly improved, and can limit guide pin bushing in guiding movement and relatively rotate with guide pillar, expands the range of this assembly apparatus.
For ease of the location of rolling member, described ball retainer two ends synchronize to move axially with guide pin bushing in being installed on guide pin bushing.
As preferred version of the present utility model, after described ball is inlaid in ball retainer, it is 0.2 1mm that ball protrudes the radial dimension of ball retainer inner periphery and the outer periphery.
For ensureing the stationarity of guiding movement, described guide pillar periphery is arranged with spring, and when guide pin bushing coordinates and imports guide pillar periphery guiding movement, described spring is against the end of ball retainer.

Detailed description of the invention
As shown in Fig. 1 Fig. 4, for linear contact lay ball guide pillar guide pin bushing assembly of the present utility model, including guide pillar 1 and guide pin bushing, it is arranged with ball retainer 3 between 2 guide pillars 1 and guide pin bushing 2, on ball retainer 3, longitudinal direction circumferentially is embedded with some row balls 4, the inner circumferential that guide pin bushing 2 is corresponding to each row ball 4 is correspondingly provided with the Inner arc chute that the cambered surface linear contact lay with ball 4 of corresponding columns coordinates, the periphery that guide pillar 1 is corresponding to each row ball is correspondingly provided with the cylindrical chute coordinated with ball 4 cambered surface linear contact lay of corresponding columns, ball 4 and the Inner arc chute of guide pin bushing 2, on the external arc chute of guide pillar 1 and ball retainer 3, the hole of setting-in rolls and coordinates.
For ease of the location of rolling member, ball retainer 3 two ends synchronize to move axially with guide pin bushing 2 in being installed on guide pin bushing 2.For optimizing the size of linear contact lay matching part, after ball 4 is inlaid on ball retainer 3, it is 0.2 1mm that ball 4 protrudes the radial dimension of ball retainer 3 inner periphery and the outer periphery.For ensureing the stationarity of guiding movement, guide pillar 1 periphery is arranged with spring 5, when guide pin bushing 2 coordinates and imports guide pillar 1 periphery guiding movement, and the end of spring 5 resilient abutment ball retainer 3.
Linear contact lay ball guide pillar guide pin bushing assembly of the present utility model, in on ball retainer 3, the projecting surface of ball is respectively embedded into the arc chute of guide pillar 1 and guide pin bushing 2, and arc chute cross section arc contacts cooperation and instead of original point cantact with the pearl face curved line of ball 4, the rigidity of linear contact lay ball guide pillar guide pin bushing assembly is made to be significantly larger than point cantact ball guide pillar guide pin bushing assembly；Simultaneously, the precompressed amount of linear contact lay guide pillar guide pin bushing assembly is significantly less than plain ball guide pillar guide pin bushing assembly, ball is not easy to be deformed, vibration operationally is minimum, precision is high, operation stability is greatly improved, and can limit guide pin bushing in guiding movement and relatively rotate with guide pillar, expands the range of this assembly apparatus.
