Abstract
The invention discloses a linear guideway assembly which is convenient to install, capable of reducing frictional resistance, and capable of automatically adjusting gaps. The linear guideway assembly comprises a slide bar, one side of the slide bar is provided with a fixed guide body, and the other side of the slide bar is provided with a guide seat and a movable guide body arranged in the guide seat. The top end of the guide seat is provided with a guide hole, the bottom of the movable guide body is provided with a guide post matched with the guide hole, and the guide post is arranged in the guide hole. A pre-tightening spring is arranged between the guide post and the bottom wall of the guide hole and arranged in the guide hole. Respective guide faces of the fixed guide body and the movable guide body are respectively provided with a plurality of placing holes, and steel balls are arranged in the placing holes, and the respective guide faces of the fixed guide body and the movable guide body are respectively provided with a baffle for preventing the steel balls from sliping off. All the steel balls are extended from corresponding baffles. The linear guideway assembly is mainly used for all kinds of machine tools.
Description
Technical field
The present invention relates to guide assembly, refer more particularly to a kind of line slideway assembly.
Background technology
The line slideway assembly is widely used in various lathes.Traditional line slideway assembly, its structure generally includes: slider bar and the guide way that is arranged on the slider bar both sides.The shortcoming of this line slideway assembly is: the gap precision between slider bar and guide way is had relatively high expectations, and installs more difficult; And frictional resistance is larger, uses for a long time serious wear, causes the gap between slider bar and guide way to increase, thereby has influence on the glacing flatness of slider bar operation.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of easy for installation, and can reduce the line slideway assembly of frictional resistance, automatic regulating gap.
for solving the problems of the technologies described above, the technical solution used in the present invention is: the line slideway assembly, comprise: slider bar, one side of slider bar is provided with the fixed guide body, the opposite side of slider bar is provided with guide holder and the activity-oriented body that is arranged in guide holder, the top of described guide holder offers pilot hole, the bottom of described activity-oriented body is provided with the lead that matches with pilot hole, lead is arranged in pilot hole, also be provided with preloading spring in pilot hole between the diapire of lead and pilot hole, offer respectively several placement holes on described fixed guide body and activity-oriented body spigot surface separately, be placed with steel ball in 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 activity-oriented body spigot surface separately, all steel balls stretch out from corresponding baffle plate.
Described slider bar is respectively arranged with the gathering sill that matches with steel ball on the spigot surface of its both sides.
Described lead is provided with the guide cylinder that matches with preloading spring on its bottom end face, preloading spring stretches in this guide cylinder.
The invention has the beneficial effects as follows: because steel ball in the present invention and slider bar are that point contacts, and steel ball can be done the rotation of any direction, thereby greatly reduces the frictional resistance between slider bar and fixed guide body and activity-oriented body; In addition, preloading spring can be adjusted the gap between slider bar and fixed guide body and activity-oriented body, makes the installation of whole line slideway assembly very convenient, and has guaranteed the glacing flatness of slider bar operation.In addition, owing to being provided with guide cylinder on the end face of the bottom of lead, make the flexible more steady of preloading spring.
