Axial positioning structure for pendulum shaft of warp knitting machine

Abstract

The invention discloses an axial positioning structure for a pendulum shaft of a warp knitting machine, which belongs to the technical field of warp knitting machines, and comprises the pendulum shaft and a connecting sleeve sleeved at the end part of the pendulum shaft, and further comprises a connecting plate, a fixing screw, a threaded shaft, a mounting screw, a wall plate, a nut and a rack, a gasket and a bolt are arranged on the rotating shaft, the rotating shaft is fixed in a hole of the mounting bearing through the gasket and the bolt, a gland is arranged on the mounting bearing, an outer ring of the mounting bearing is fixed in the connecting sleeve through the gland, the other end of the connecting sleeve is sleeved on the swing shaft, a groove is formed in the other end of the shaft, and the swing shaft is fixed in the groove. One end of the connecting plate is arranged in a groove of the shaft, the connecting plate and the shaft are fastened and fixed through the fixing screw, the other end of the connecting plate is arranged in a groove of the threaded shaft, the connecting plate and the threaded shaft are fastened and fixed through the mounting screw, and the threaded shaft is screwed in a wallboard screw hole. The device is easy to operate and convenient to install and maintain.

Description

technical field [0001] The invention relates to the technical field of warp knitting machines, in particular to an axial positioning structure of a pendulum shaft of a warp knitting machine. Background technique [0002] The warp knitting machine is a fabric formed by the reciprocating motion of various knitting needles and the lateral movement of the guide needle. For each needle bed, the main arm of each needle bed is installed on a pendulum shaft, and the pendulum shaft is oscillated by a certain angle through a link movement mechanism or a cam mechanism, so that various needle beds are oscillated to realize the required knitting motion. The knitting needles on various needle beds have a small distance from each other according to the fineness of the fabric. In order to prevent the knitting needles from colliding during knitting, it is necessary to enable the needle beds to be positioned accurately in the axial direction. For this reason, the main arm of each needle bed ...

Problems solved by technology

[0004] However, the disadvantage of the above-mentioned patent is that the swing of the pendulum shaft is elastically absorbed by the torsion rod, the swing angle of the pendulum shaft must be small, and the position of the torsion rod must be adjusted, otherwise the torsion rod will be plastically deformed and hardened; the structure is more complicated, and installation and maintenance are difficult
