Abstract
The utility model provides a Y-axis ball screw comprising a screw body (1) in the Y-axis direction, and a screw sleeve (3), wherein a ring of bearing sleeve (2) is arranged in the middle of the screw body (1), and the screw sleeve (3) is movably sheathed on the bearing sleeve (2). The Y-axis ball screw has the advantages that the structure is simple, the sliding effect is better, and as balls are arranged, and the screw body is arranged in the Y-axis direction, the screw sleeve can slide on the screw forth and back smoothly; and when being fixed on the screw sleeve, a camera fixing plate or a wire fixing plate can slide on the screw body forth and back, so that the sliding effect is smoother.
Description
Technical field
The utility model relates to a kind of Y shaft ball screw.
Background technique
In some product facilities, understand mobile device usually, have plenty of and move forward and backward; What have then is to need move left and right; Some equipment in the process that moves, require comparatively strict, need be comparatively accurate to the direction that moves and mobile displacement; But do not exist some to move comparatively accurate instrument in some equipment of present stage, like moving of camera fixing plate; Moving of electric wire fixed plate, mobile effect are not very desirable.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of camera fixing plate or electric wire fixed plate of can sliding in front and back, and sliding effect Y shaft ball screw preferably.
For realizing above-mentioned purpose, the utility model provides a kind of Y shaft ball screw, and it includes screw mandrel body, the screw mandrel cover of Y direction, and the neutral position of said screw mandrel body is provided with a circle bearing housing, and said screw mandrel cover is movably set on the bearing housing.
More excellent is to be provided with a plurality of balls between said screw mandrel cover and the bearing housing.
More excellent is that the diameter at the two ends of said screw mandrel body is less than the diameter of screw mandrel body intermediate section.
The advantage of the utility model Y shaft ball screw is: simple in structure; Sliding effect is better; Through the setting of ball, and because the screw mandrel body is to be in Y direction, then can be so that the level and smooth front and back slip on screw mandrel of screw mandrel cover; Some camera fixing plates or electric wire fixed plate are fixed on screw mandrel put, then can slide in front and back and sliding effect is comparatively level and smooth so that camera fixing plate or electric wire fixed plate carry out on the screw mandrel body.
Description of drawings
Accompanying drawing 1 is the plan view of the utility model Y shaft ball screw;
Accompanying drawing 2 is the side view of the utility model Y shaft ball screw.
Among the figure:
1-screw mandrel body; The 2-bearing housing; 3-screw mandrel cover; The 4-ball.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
Shown in accompanying drawing 1, accompanying drawing 2, a kind of Y shaft ball screw, it includes screw mandrel body 1, the screw mandrel cover 3 of Y direction, and the neutral position of screw mandrel body 1 is provided with a circle bearing housing 2, and screw mandrel cover 3 is movably set on the bearing housing 2.
Wherein, be provided with a plurality of balls 4 between screw mandrel cover 3 and the bearing housing 2, the slip before and after screw mandrel cover 3 can be done through the rolling of ball 4 on screw mandrel body 1.
In addition, the diameter at the two ends of screw mandrel body 1 is less than the diameter of screw mandrel body 1 intermediate section.
The above; Be merely the embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model disclosed, and variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
