Abstract

The invention discloses a spindle assembly of a rapier loom and a left-right weft insertion phase adjusting method. The spindle assembly of the rapier loom comprises a rotating arm and a weft insertion gear, wherein the rotating arm drives a left weft insertion mechanism and drives a left rapier head to move; the weft insertion gear drives a right weft insertion mechanism and drives a right rapier head to move; the rotating arm is fixedly connected with a left beating-up cam through a friction force; one end of a main transmission shaft is fixedly connected with the left beating-up cam through the friction force, and the other end of the main transmission shaft is fixedly connected with a right beating-up cam through the friction force; the weft insertion gear is fixedly connected with the right beating-up cam through a bolt and a locating pin; the left beating-up cam is connected with a left wallboard through a bearing; the right beating-up cam is connected with a right wallboard through a bearing; a breast beam is fixedly connected with the left wallboard and the right wallboard through bolts. The left-right weft insertion phase adjusting method is characterized by adjusting initial phases of left weft insertion motion and right weft insertion motion according to needs, and comprises the following steps: inserting an adjusting tool in an adjusting hole in the rotating arm; enabling a C surface of the head part of the adjusting tool to enter A key grooves in the surfaces of beating-up cams; rotating the adjusting tool.

Description

technical field [0001] The invention relates to a main shaft assembly of a rapier loom and a method for adjusting the left and right weft insertion phases, and belongs to the mechanical structure and parameter adjustment technology in the field of textile machinery. Background technique [0002] figure 1 Shown is an existing main shaft assembly of a rapier loom, which includes a left camshaft 1 with a left weft insertion conjugate cam surface A and a left beat-up conjugate cam surface B, the left camshaft 1 The main transmission shaft 6 is fixedly connected through a coupling joint 5 and a flat key 8. At the same time, the right camshaft 2 with the right weft insertion conjugate cam-shaped surface A' and the right beating-up conjugate cam-shaped surface B' is also passed through a coupling joint. 5 and the flat key 8 are fixedly connected with the main transmission shaft 6; the left camshaft 1 is connected with the left case cover 3 through a bearing, and the left case cove...
