Problems solved by technology

In order to enable the ball scale to measure in the circumferential direction, the applicant is designing a ball scale with a circular scale body. The reading head needs to slide the entire circumference of the scale body to achieve its circumferential direction. Movement, the reading head must sequentially span each support seat, so that the contact support between the support seat and the ruler body must be separated and closed, and the existing support seat is firmly connected with the ruler body. Obviously, the existing The support seat cannot be used on the ball scale with a circular scale body

Embodiment Construction

[0012] figure 1 , 2 As shown, the support seat for the ball scale of the present invention includes a base 6, a support arm 7 is hinged on the base 6 through a pin, and the end of the support arm 7 away from the base 6 is mounted with a support body with a positioning groove through a pin. 8. The supporting body 8 is a sheave wheel, wherein the ruler body 1 is located in the positioning groove of the supporting body 8 and is positioned and matched with the positioning groove. In addition, the end of the support arm 7 away from the base 6 is also provided with an electromagnet 9 for holding the ruler body 1. The electromagnet 9 has a U-shaped structure, and the support body 8 is located between two parallel side walls of the U-shaped structure of the electromagnet 9 between. Two torsion springs 10 are provided between the support arm 7 and the base 6; the two torsion springs 10 are respectively installed on the front and rear ends of the pin, and the torque directions of the two...

Abstract

The present invention relates to a supporting seat used for a ball bar ruler which includes a subbase, a support arm is revoluted assembled on the subbase through a revolution axis, one end far away the subbase is equipped with a supporting body with a locating slot, one end of the support arm far away the subbase also is equipped with an electro-magnet for absorbing the ball bar ruler body, a torsion spring is set between the support arm and the subbase. The support seat solves support problem of the ball bar ruler with annual shape ruler body.

Description

Technical field [0001] The invention relates to a support seat for a ball grid, in particular to a support seat for a ring-shaped ball grid. Background technique [0002] The ball grid (also known as the ball sensor ruler, also known as the ball synchronizer) is the latest generation of length measurement sensors in the world. It has the advantages of anti-interference, anti-vibration, anti-pollution, reliability and durability, so it is gradually promoted to be used in machinery In the processing industry. The existing ball grids are all linear structures, that is, they include a straight ruler body composed of a metal tube and high-precision steel balls closely arranged in the metal tube; the ruler body slides through a reading head, Both ends of the ruler body are fixedly provided with support seats for fixing the ruler body to the machine tool, and this kind of ball scale can only be used to accurately measure linear displacement. In order to enable the ball scale to be abl...
