Embodiment 1

[0023] A cam 2 adjustment mechanism, including a fixedly installed limit ring 1, a cam 2 that cooperates with the limit ring 1 and is limited by the limit ring 1, and the cam 2 is fixedly connected with a connecting ring that matches the limit ring 1 3. The inner ring of the cam 2 and the connecting ring 3 is circular; the contact surface between the connecting ring 3 and the limiting ring 1 is uniformly provided with several axial positioning parts along the circumferential direction, and the positioning parts are arranged axially along the limiting ring 1 The positioning grooves 4; the adjacent positioning grooves 4 are parallel to each other, the upper end of the positioning grooves 4 is provided with an arc-shaped gap, and the central axis of the arc is located at the center line of the positioning grooves 4. The contact surface between the limiting ring 1 and the connecting ring 3 is provided with at least one fixing part 5 matched with the positioning part, and the fixing...

Abstract

A cam regulation mechanism comprises a limit ring and a cam, wherein the limit ring is fixedly arranged, the cam is matched with the limit ring and limited by the limit ring, a connection ring matched with the limit ring is fixedly connected with the cam, and inner ring of the cam and the inner ring of the connection ring are circular. A plurality of axial positioning portions are evenly arranged on the contact surface of the connection ring and the limit ring in the circumferential direction, and at least one fixing portion matched with the positioning portions is arranged on the contact surface of the limit ring and the connection ring. The cam regulation mechanism is high in fixation reliability, and drive failure caused by the fact that the cam regulation mechanism slides in the usage process is avoided.

Description

technical field [0001] The invention relates to a cam adjustment mechanism, which belongs to the field of loom manufacturing. Background technique [0002] In a traditional loom, it is often a power source, which drives all components to work together and interact with each other through various drive shafts. In the linkage mechanism, the cam is used to convert circular motion into reciprocating motion, which is a widely used structure. In the linkage process, the phase relationship between circular motion and reciprocating motion is often adjusted through the positional relationship of the cam relative to the shaft. There are roughly two adjustment methods at present: one is to use a shaft with a circular cross section, and the cam is fixed by a hoop on the rotating shaft, and are fixed to the rotating shaft by the friction force on the inner surface of the hoop; one is to use a rotating shaft with a non-circular cross section, such as a square shape. The reliability of t...
