Abstract
In a linear guide device comprising: a guide rail fixedly secured to the mounting surface of a supporting member such as a machine bed; and a slider slidably engaged with the guide rail. Recesses are formed in the mounting surface of the guide rail and in the mounting surface of the supporting member, respectively, to provide a space therein. The space thus provided is filled with a hardenable filling material. The hardenable filling material is solidified therein, thus serving as a key held between the guide rail and the supporting member to prevent the guide rail from being displaced sidewards.
Claims10
A linear guide device comprising:
- a guide rail fixedly secured by a bolt member to the mounted surface of a supporting member adapted to support said linear guide device;
- a slider engaged with said guide rail so as to be movable relative to said guide rail;
- and
- a guide rail sideward displacement preventing mechanism in which recesses are formed in the mounting surface of said guide rail and in the mounted surface of said supporting member which is in contact with the mounting surface of said guide rail, respectively, to provide a space therein, and said space thus provided is filled with a hardenable filling material, and said hardenable filling material is solidified therein.
A linear guide device comprising:
- a guide rail secured to a base by a bolt member, said guide rail having ball rolling grooves in its both side walls;
- a slider body slidably engaged with said guide rail, said slider having ball rolling grooves disposed in opposed relation to said ball rolling grooves of said guide rail and ball returning paths formed in parallel to said ball rolling grooves thereof;
- end caps secured respectively to both ends of said slider body, said end caps having curved paths for communicating said ball returning path and a space defined by said opposed ball rolling grooves;
- a plurality of balls inserted in a endless circulating path which was constructed by said curved path, said returning path and said space defined by said opposed ball rolling grooves;
- and
- a means for preventing said guide rail from being displaced sideward, said displacement preventing means is a hardenable filling material filling into a space defined by a first recess member and a second recess member, in which said first recess member is formed in a mounted surface of said base on which said guide rail is mounted and said second recess member is formed on a mounting surface of said guide rail which is in contact with the mounted surface of said base, and said hardenable filling material is solidified in said space.
