High precision encoder installing and connecting apparatus

Abstract

The invention provides a high-precision coder mounting connecting device, which comprises a rigid connecting piece (4) and an elastic strip (2). One end of the rigid connecting piece (4) is positioned and mounted with a measurement shaft, and the other end is in clearance socket joint with the coder. The end of the rigid connecting piece (4), connected with the coder, is provided with at least two rows of micrometric regulating screws (1) radially arranged, and each row is provided with three screws which are uniformly distributed along the periphery. One end of the elastic strip (2) is connected with a shell (3) of the coder, and the other end is connected with a fixed base (5). By adopting the mounting connecting structure of rigid connection and flexible suspension, the device can micrometrically and accurately regulate the position of the shaft of the coder in a hole by virtue of two rows of radial trisector micrometric regulating screws and achieve rigid fixation, thus realizing the high coaxiality requirement with the measurement shaft; by adopting the flexible suspension of the elastic strip to connect the shell of the coder with the fixed base, the device only limits the circumferential revolution degree of freedom of the shell of the coder, thus avoiding generating positioning interference with a rigid fixed axle and affecting the adjustment of the coaxiality.

Description

technical field [0001] The invention relates to an encoder connection device, in particular to a precisely adjustable rigid connection + flexible suspension high-precision encoder installation connection device. Background technique [0002] As a strategic industry, machine tool equipment has always been highly valued by countries all over the world. In recent years, machine tool equipment has been developing in the direction of digitalization, high precision, and multi-axis. As the "commanding height" of machine tool technology, the five-axis linkage CNC machine tool and the CNC gear grinding machine known as the "pearl in the crown", etc., have not only linear motion coordinate axes, but also rotary motion coordinate axes. [0003] In order to improve the rotation control accuracy of the rotary motion coordinate axis, in addition to improving the manufacturing accuracy of the transmission parts, another measure is to adopt closed-loop control, and one of the keys to close...
