Abstract
The utility model discloses a rolling linear guide rail pair. The rolling linear guide rail pair comprises a guide rail, a slide block and a rolling body holding device, wherein ball reversers are fixedly arranged at two ends of the slide blocks respectively; the rolling body holding device comprises an upper holding rack, an intermediate holding rack and a lower holding rack. The rolling linear guide rail pair is characterized in that joints are integrally arranged at two end parts of the intermediate holding rack, a groove is formed in the inner side of each joint, projections corresponding to the grooves in position and protruding toward the intermediate holding rack are arranged on the ball reversers, each projection forms a slot together with the inner surface of the slide block, the joints are inserted into the slots, and the projections are inserted into the grooves. The rolling linear guide rail pair has the advantages that as the joints on the intermediate holding rack are inserted into the slots formed by the projections on the ball reversers and the slide block, and the projections on the ball reversers are inserted into the grooves of the intermediate holding rack, the intermediate holding rack is fixed and can be kept stable during high-speed operation, abrasion is avoided, and the service life of the rolling linear guide rail pair is ensured; besides, installation of the intermediate holding rack is simplified and can be realized without the need of additional tools, so that the assembly efficiency is improved.
Description
Technical field
The utility model relates to a kind of linear rolling guide.
Background technique
Linear rolling guide is widely used in the various electromechanical integration equipments.In more existing linear rolling guides with the rolling element holding device, and the rolling element holding device mainly comprises holder, middle retainer and lower retainer, upper and lower retainer is fixed by the socket on the ball reverser in the linear rolling guide, middle retainer then floats and is installed between the ball reverser at slide block two ends, because middle retainer is in quick condition, so that middle retainer is difficult for installing, and when high speed operation, middle retainer is unstable, wearing and tearing have been so that shortened the working life of linear rolling guide easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of linear rolling guide of installing easily and can avoid middle retainer wearing and tearing when high speed operation.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of linear rolling guide, comprise guide rail, slide block and rolling element holding device, the two ends of described slide block are fixedly installed respectively the ball reverser, described rolling element holding device is positioned at described slide block, described rolling element holding device comprises holder, middle retainer and lower retainer, the two ends of described holder and described lower retainer are plugged on respectively on the described ball reverser, the two end part of described middle retainer have been wholely set joint, the inboard of described joint is provided with groove, be wholely set corresponding with described groove location on the described ball reverser and to the outstanding projection of described middle retainer direction, the internal surface of described projection and described slide block forms a slot, described joint inserts in the described slot, and described projection inserts in the described groove.
Compared with prior art, the utility model has the advantages that because in the projection and the formed slot of slide block on the joint insertion ball reverser on the middle retainer, and during the projection on the ball reverser inserts in the groove of retainer, so that middle retainer is fixed, when high speed operation, can keep stable, and after owing to be fixed all the time with linear rolling guide in ball and guide rail keep certain gap, thereby avoided wearing and tearing, guaranteed the working life of linear rolling guide; In addition, simplified the installation of middle retainer, need not to have improved efficiency of assembling by extra frock.
