Description
Technical field
The utility model relates to a kind of the friction type straight line motion track, and it provides non-two objects with material to carry out linear relative movement with the line contact or the face way of contact, and the guiding structure of tool self-aligning device, pressure regulation device.
Background technique
Known straight line motion track structure (seeing also shown in Figure 1), provide two objects to carry out linear relative movement, and has a structure that reduces resistance and guiding, in this class formation, its bearing assembly inside has the passage that is positioned at upper and lower and is interconnected, a plurality of steel balls are set in this passage, and this steel ball is through being the endless form rolling in the passage at this upper and lower after the friction when track and bearing assembly relative movement.Yet though the mode of some contact circulating rolling can reduce its contact friction force, the mode of some contact but can't be born bigger impact force and be damaged easily, and steel ball has the problem of beating when shuttling movement, easily causes vibrating.
In addition, known straight line motion track structure there is no the self-aligning device, and bearing assembly can produce the point of contact displacement because of machining error or distortion, causes inclination, cause all loads only to be born, and then reduce life of product and bearing capacity by diagonal angle steel ball and guide channel.
In addition, known straight line motion track structure there is no pressure regulation device, can't adjust the distance of both sides sliding assembly group, the big variable in distance that this is produced from the both sides arrangement for guiding apart from correspondence.
Again in addition, known track and arrangement for guiding adopt one-body molded, difficulty in heat treatment and when grinding, and easily deformable and crooked, and the steel ball in the bearing assembly not only manufacturing technology is higher, its assembling also is not easy.Therefore, the inventor is based on aforementioned reason, thereby improves the shortcoming that straight line motion track technology commonly used is had.
The model utility content
The friction type straight line motion track of the present utility model, one straight line tracks mainly is provided and is arranged at the parallel arrangement for guiding in track both sides, and by sliding assembly contact with line between arrangement for guiding or some contact but acyclic rolling as the straight line motion between bearing assembly and the track, therefore this mode has advantages of high bearing capacity than a some contact circulating rolling, and vibrative problem when not having circulating rolling; In addition, the friction type straight line motion track of the present utility model is provided with the self-aligning device, can adjust contact position automatically according to different machining error and amount of deformation, to keep due life-span of product and bearing capacity.
Another purpose of the utility model the friction type straight line motion track, for a groove is set by track, in order to hold and fixing arrangement for guiding, therefore track must not done heat treatment, and the processing that only need make to hold arrangement for guiding gets final product, and arrangement for guiding also can easily be obtained with commodity basis, and be easy to apply heat treatment and grinding, therefore can reduce the required technical difficulty degree of establishment of component, and promote its assembling performance, and further reduce cost.
Based on aforementioned purpose, the friction type straight line motion track of the present utility model has: a track, and it has several arrangement for guiding, and these arrangement for guiding be arranged in parallel along the track both sides; And a bearing assembly, be arranged with several sliding assembly in it in parallel, and these sliding assembly corresponding these arrangement for guiding are set; Wherein, these arrangement for guiding have the arcuation profile, can contact with line with the arcuation profile of sliding assembly in the bearing assembly or mode that point contacts mutually against, and do non-longitudinal sliding motion with the line between material material friction or some the friction type, so that sliding friction is given birth to when hot, can not produce the material fusion phenomenon.
For making those skilled in the art understand the purpose of this utility model, feature and effect, now by following specific embodiment, and cooperate appended accompanying drawing, be described as follows in detail.
