The linear guide rail assembly comprises a sliding bar, wherein one side of the sliding bar is provided with a fixed guide body while the other side of the sliding bar is provided with a guide seat and a movable guide body in the guide seat; the top end of the guide seat is provided with a guide hole; the bottom part of the movable guide body is provided with a guide pillar which is matched with and arranged in the guide hole; a preloaded spring is further arranged in the guide hole between the bottom walls of the guide pillar and the guide hole; a plurality of placing holes are respectively formed in the guide surfaces of the fixed guide body and the movable guide body; steel balls are placed in the placing holes; at least one baffle for preventing the steel balls from slipping is also arranged on the guide surface of each of the fixed guide body and the movable guide body; and all the steel balls stretch out from the corresponding baffles. The linear guide rail assembly is mainly applied to various machine tools.
Description
Technical field
The utility model relates to guide assembly, refers more particularly to a kind of linear rail assembly.
Background technique
The linear rail assembly is widely used in the various lathes.Traditional linear rail assembly, its structure generally includes: slidable bar and the guide way that is arranged on the slidable bar both sides.The shortcoming of this linear rail assembly is: the gap precision between slidable bar and the guide way is had relatively high expectations, and relatively difficulty is installed; And surface friction drag is larger, uses for a long time serious wear, causes the gap between slidable bar and the guide way to increase, thereby has influence on the straightness of slidable bar operation.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of easy for installation, and can reduce the linear rail assembly of surface friction drag, automatic regulating gap.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the linear rail assembly, comprise: slidable bar, one side of slidable bar is provided with the fixed guide body, the opposite side of slidable bar is provided with guide holder and the activity-oriented body that is arranged in the guide holder, the top of described guide holder offers pilot hole, the bottom of described activity-oriented body is provided with the directional post that matches with pilot hole, directional post is arranged in the pilot hole, between the diapire of directional post and pilot hole, also be provided with preloading spring in the pilot hole, offer respectively several placement holes on described fixed guide body and the activity-oriented body guide surface separately, be placed with steel ball in the placement hole, also be respectively arranged with at least one baffle plate that is used for stopping the steel ball slippage on fixed guide body and the activity-oriented body guide surface separately, all steel balls stretch out from corresponding baffle plate.
The guide surface of described slidable bar in its both sides is respectively arranged with the guiding groove that matches with steel ball.
Described directional post is provided with the guide cylinder that matches with preloading spring at its bottom end face, and preloading spring stretches in this guide cylinder.
The beneficial effects of the utility model are: because steel ball contacts for point with slidable bar in the utility model, and steel ball can be done the rotation of any direction, thereby greatly reduces the surface friction drag between slidable bar and fixed guide body and the activity-oriented body; In addition, preloading spring can be adjusted the gap between slidable bar and fixed guide body and the activity-oriented body, so that the installation of whole linear rail assembly is very convenient, and has guaranteed the straightness that slidable bar moves.In addition, owing to be provided with guide cylinder at the bottom of directional post end face, so that preloading spring is flexible more steady.
