Technical field
The utility model relates to a kind of linear guide pairs, especially relates to the rolling element back holding device in a kind of linear rolling guide.
Background technique
Linear rolling guide is widely used in various electromechanical integration equipments.More existing linear rolling guides mainly comprise guide rail, slide block, rolling element holding device, ball catch and ball, the two ends of slide block are respectively arranged with rolling element reverser, rolling element holding device is positioned at slide block, rolling element holding device generally includes and is connected in two holder and lower retainers between rolling element reverser, the two ends of the two ends of holder and lower retainer are all plugged on rolling element reverser by the socket being arranged on rolling element reverser, and ball catch is installed on the inner side end of rolling element reverser.This linear rolling guide is because the termination of holder and the termination of lower retainer are all that socket by being arranged on rolling element reverser is realized fixing, therefore very easily because the processing problems of rolling element reverser and holder and lower retainer causes jointing out-of-flatness, discontinuous, and rolling element is paused at back outlet port card, cause producing vibration in slide block running, finally affect the overall precision of linear rolling guide.
Summary of the invention
Technical problem to be solved in the utility model is to provide the rolling element back holding device in a kind of linear rolling guide, and it is simple in structure, efficiency of assembling is high, and can effectively avoid the slide block in linear rolling guide in running, to produce vibration.
The utility model solves the problems of the technologies described above adopted technological scheme: the rolling element back holding device in a kind of linear rolling guide, it is characterized in that comprising two integrated type back retainers, the rolling element reverser that described integrated type back retainer is formed by integrated injection molding and half holder form with half lower retainer, the free end that is integrally formed at half holder on the rolling element reverser described in one of them be integrally formed at another described in rolling element reverser on the free end of half holder be fixedly connected with formation holder, the free end that is integrally formed at half the lower retainer on the rolling element reverser described in one of them be integrally formed at another described in rolling element reverser on the free end of half lower retainer be fixedly connected with and form lower retainer.
Be integrally formed on the free end of half holder on the rolling element reverser described in one of them and be provided with the first inserting column, be integrally formed on the free end of half holder on the rolling element reverser described in another and be provided with the first jack matching with the first described inserting column; Be integrally formed on the free end of half the lower retainer on the rolling element reverser described in one of them and be provided with the second inserting column, be integrally formed on the free end of half the lower retainer on the rolling element reverser described in another and be provided with the second jack matching with the second described inserting column; At this, utilize the cooperation of inserting column and jack to realize being simply fixedly connected with of corresponding half holder and being fixedly connected with of half lower retainer accordingly.
Moving direction along the guide rail in linear rolling guide is provided with the auxiliary raceway of ball on the outer side surface of the slide block of described holder in linear rolling guide and on the outer side surface of the described lower retainer slide block in linear rolling guide; At this, by the auxiliary raceway of ball is set, can form a raceway with the ball road that arranges on slide block, can be good at keeping ball stable rolling in raceway.
Compared with prior art, the utility model has the advantage of: by two integrated type back retainers, formed by rolling element back holding device is designed to, and the rolling element reverser that integrated type back retainer is formed by integrated injection molding and half holder form with half lower retainer, because one end of half holder descends one end of retainer to be all wholely set with rolling element reverser with half, jointing is smooth and coherent, the oscillation phenomenon of generation while therefore effectively having eliminated the slide block operation that ball causes because of pausing at back outlet port card, thereby effectively guaranteed the overall operation precision of linear rolling guide, in addition, when assembling, only need be fixedly connected with being integrally formed at two half holders on integrated type back retainer, half the lower retainer being integrally formed on two integrated type back retainers is fixedly connected with, not only simplified the structure of rolling element back holding device, and simplified the assembling of holder and lower retainer, improved efficiency of assembling.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of rolling element back holding device of the present utility model;
Fig. 2 is the structural representation of the integrated type back retainer in rolling element back holding device of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Rolling element back holding device in a kind of linear rolling guide the utility model proposes, as shown in the figure, it comprises two integrated type back retainers 1, the rolling element reverser 11 that integrated type back retainer 1 is formed by macromolecular material integrated injection molding and half holder 12 and half lower retainer 13 form, the free end that is integrally formed at half holder on one of them rolling element reverser is fixedly connected with formation holder with the free end that is integrally formed at half holder on another rolling element reverser, the free end that is integrally formed at half the lower retainer on one of them rolling element reverser is fixedly connected with and forms lower retainer with the free end that is integrally formed at half the lower retainer on another rolling element reverser, during slide block in assembling two integrated type back retainers 1 and linear rolling guide, one of them integrated type back retainer is placed in to one end of slide block, another integrated type back retainer is placed in to the other end of slide block, then the free end that is integrally formed at half holder on one of them rolling element reverser is fixedly connected with the free end that is integrally formed at half holder on another rolling element reverser, and the free end that is integrally formed at half the lower retainer on one of them rolling element reverser is fixedly connected with the free end that is integrally formed at half the lower retainer on another rolling element reverser, now one of them rolling element reverser is positioned at one end of slide block, another rolling element reverser is positioned at the other end of slide block, holder and lower retainer are positioned at slide block.
