Abstract
The utility model relates to a reading head of a ball grid ruler, which comprises a housing and a collection coil arranged in the housing, wherein, a channel allowing the ruler body of the ball grid ruler to pass through and provided with a circular cross section is arranged in the collection coil, and the channel adopts the circular arc-shaped channel correspondingly matched with the annular ruler body for passing through. The channel in the collection coil inside the reading head adopts the circular arc-shaped channel, the channel is used for penetrating the annular ruler body, and the reading head is used for moving along the annular ruler body for carrying out measurement; as the motion route of the reading head is circular, and the measurement quantity thereof represents arc length orrotation angle, thereby meeting the requirement of using the ball grid ruler to carry out circumferential measurement.
Description
Technical field
The utility model relates to a kind of ball bar ruler, particularly a kind of ball bar ruler read head.
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; Sliding on the blade is equipped with a read head, and the two ends of blade are installed with and are used for blade is fixed to supporting seat on the lathe, and 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 arc length or the anglec of rotation.
The utility model content
The purpose of this utility model provides a kind of read head that is used on the annular ball bar ruler, makes ball bar ruler can carry 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 read head, comprise shell and be arranged at the interior collection coil of shell, be provided with the xsect of walking for the ball bar ruler blade in the described collection coil and be circular passage, described passage is the circular arc passage that is used for the corresponding cooperation of annular blade of walking.
Passage in the collection coil in the read head of such scheme is the passage of a circular arc, this passage is used for installing the blade of annular, read head is used for moving along annular blade and measures, 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;
Fig. 2 is the left view of Fig. 1.
Embodiment
Shown in Fig. 1,2, a kind of ball bar ruler read head of the present utility model, comprise shell 1, the both sides of shell 1 are equipped with the circular hole 4 that is used to wear the annular blade, shell 1 internal fixation has the coil 3 of collection, gather in the coil 3 and have a passage that is used to wear annular blade, and this passage and described circular hole 4 are on the camber line of same curvature.The outside of gathering coil 3 also is provided with a magnetizing coil 2.Wherein, gather coil 3 and gather sub-coils by six groups and forms, every group of collection sub-coil all excited by four separate having and the coil of receiving function is formed.
Claims (1)
1. ball bar ruler read head, comprise shell and be arranged at the interior collection coil of shell, be provided with the xsect of walking for the ball bar ruler blade in the described collection coil and be circular passage, it is characterized in that: described passage is the circular arc passage that is used for the corresponding cooperation of annular blade of walking.
