Abstract
The utility model relates to a ruler body of a ball grid ruler, the ruler body comprises a metal pipe outer sleeve and a precision steel ball tightly arranged in the metal pipe outer sleeve, and the metal pipe adopts a closed circular ring. As the ruler body adopts the circular ring structure, the adoption of a reading head of the ball grid ruler of the ruler body can carry out circumferential movement along the ruler body, thereby being capable of carrying out circumferential length measurement or rotation angle measurement.
Description
Technical field
The utility model relates to a kind of ball bar ruler, particularly a kind of ball bar ruler blade.
Background technology
Ball bar ruler (not only be feel of the ball chi but also the ball of title synchronizer is arranged) is a latest generation length measuring sensor in the world at present, and it has anti-interference, anti-vibration, antipollution and advantage such as reliability and durability, therefore is applied in the mechanical processing industry gradually.Existing ball bar ruler is rectilinear structure, and promptly it comprises a straight blade, and blade is made up of a metal tube and the steel ball with high precision that closely is arranged in the metal tube; Slide on the blade and be equipped with a read head, the two ends of blade are installed with and are used for blade is fixed to supporting seat on the lathe, obviously, this ball bar ruler can only be used for measuring straight-line displacement accurately, and can not directly be used for measuring accurately the circumferential distance or the anglec of rotation.
The utility model content
The purpose of this utility model provides a kind of ball bar ruler blade, makes ball bar ruler can directly be used for carrying out arc length and measures or rotation angle measurement.
For achieving the above object, the utility model adopts following technical scheme: a kind of ball bar ruler blade, this blade comprise the metal tube overcoat and closely are arranged in the interior accurate steel balls of metal tube overcoat that described metal tube is the annulus of a sealing.
Described annulus is made up of at least two sections identical circular arc metal tubes of model.
Because blade adopts circular ring structure, then adopt the read head of the ball bar ruler of this blade to carry out circumferential mobile the measurement along blade, because the moving line of read head is circular, then its measuring amount is the arc length or the anglec of rotation, thereby has realized that ball bar ruler carries out circumferential Testing requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Shown in Figure 1, a kind of ball bar ruler blade of the present utility model comprises the closed circle that is formed by two identical semicircle metal tube 1 butt joints of model, wherein, closely is placed with the high-precision steel ball 2 of a circle in the caliber of closed circle.The diameter of steel ball 2 equates with the internal diameter of metal tube 1.
Claims (2)
1. ball bar ruler blade, this blade comprise the metal tube overcoat and closely are arranged in accurate steel balls in the metal tube overcoat that it is characterized in that: described metal tube is the annulus of a sealing.
2. ball bar ruler blade according to claim 1 is characterized in that: described annulus is made up of at least two sections identical circular arc metal tubes of model.
