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, on which a support arm 7 is hinged by a pin, and a support body with a positioning groove is installed on the end of the support arm 7 away from the base 6 by a pin 8. The supporting body 8 is a sheave, wherein the ruler body 1 is located in the positioning groove of the supporting body 8, and realizes positioning cooperation 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 is a U-shaped structure, and the support body 8 is located between two mutually parallel side walls of the U-shaped structure of the electromagnet 9. between. Two torsion springs 10 are arranged 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 torsion 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 scale, in particular to a support seat for a circular ball scale. Background technique [0002] Ball grid ruler (also known as ball sense ruler, also known as ball synchronizer) is the latest generation of length measurement sensor in the world at present. It has the advantages of anti-interference, anti-vibration, anti-pollution, reliability and durability, so it is gradually popularized in mechanical in the processing industry. The existing ball scales are linear structures, that is, it includes a straight ruler body, the ruler body is composed of a metal tube and high-precision steel balls tightly arranged in the metal tube; a reading head is slid on the ruler body, Both ends of the scale body are fixed with support seats for fixing the scale body to the machine tool. This kind of ball scale can only be used to accurately measure linear displacement. In order to enable the ball scale to measure in...
