Silk thread clamping, positioning and tensioning device for synchronous rotary table

Abstract

The invention discloses a silk thread clamping, positioning and tensioning device for a synchronous rotary table, which is characterized by comprising two rotary tables which are oppositely arranged, the rotary table for fixing the beginning and tail ends of the silk thread is an open side rotary table, and the rotary table for fixing the middle part of the silk thread is a closed side rotary table; the opening side rotary table comprises a bottom plate, a translation plate is arranged on the bottom plate, two stand columns are transversely arranged on the translation plate and used for fixing a pay-off structure with two wire grooves, and the first wire groove is consistent with the rotating center of the rotary table. A square plate is further arranged on the translation plate, one end of the square plate is vertically and fixedly connected with the translation plate, and a tensioning fixing block is arranged at the other end of the square plate; a hole is formed in the center of the square plate, the first coaxial tensioning structure obliquely penetrates through the hole and then is connected with the starting end of a silk thread bypassing the first wire groove, and the other end of the first coaxial tensioning structure is connected with one end of the tensioning fixing block. One end of a horizontally-arranged second coaxial tensioning structure is connected with the tail end of the silk thread bypassing the second wire groove, and the other end of the horizontally-arranged second coaxial tensioning structure is connected with the tensioning fixing block; and the closed side turntable and the open side turntable are basically consistent in structure.

Description

technical field [0001] The invention belongs to the technical field of synchrotron radiation, and in particular relates to a wire clamping, positioning and tensioning device for a synchronous turntable. Background technique [0002] In the collimation of particle accelerators, the traditional pre-collimation method based on the magnet mechanical center introduces the deviation between the mechanical center and the magnetic center. The method of replacing the physical center with the mechanical center no longer meets the accuracy requirements of the future light source, and the magnetic center of the magnet must be pre-aligned. Alignment and extraction. The rotating line collimation technology can realize the pre-collimation and extraction of the magnetic center, and measure the magnetic center position of the magnet through the rotating line, so as to align the magnetic center of the magnet equipment of the particle accelerator to the theoretical position.
