Stroke-correction transverse transmission mechanism of stretch yarn machine

Abstract

The invention relates to a stroke-correction transverse transmission mechanism of a stretch yarn machine, which belongs to the field of machine manufacture. The stroke-correction transverse transmission mechanism comprises a stepping motor, a chain wheel, a camshaft, a first auxiliary bearing, a cam, a sliding bush, a slider, a pressure plate, a second auxiliary bearing, a cam bush, and a slidingbar, wherein the stepping motor is fixedly connected with the chain wheel, the camshaft and the cam; the sliding bush, the slider and the sliding bar are fixedly connected with each other; the camshaft is connected with the cam bush through the first auxiliary bearing and the second auxiliary bearing; the sliding bush is connected in a cam slot in a rolling way; and the position of the sliding bar is limited by grooves of the pressure plate and the cam bush. The invention uses the stepping motor as the transmission source, thereby having the advantage of high transmission accuracy; the monopulse angle can be accurate to 0.04 DEG; the clear point position after the transverse movement is accurate; and the invention overcomes the inertial error caused by variations in load, accurately controls the transverse step length and can regulate the length freely. The sliding bush carries out the transmission in the cam slot in a rolling friction mode, which is sliding friction in the prior art,thereby realizing control with high precision and high efficiency.

Description

technical field [0001] The invention relates to a traversing transmission mechanism, in particular to a traversing transmission mechanism for stroke correction of an elastic thread machine, and belongs to the field of mechanical manufacturing. Background technique [0002] At present, the stroke correction traverse transmission mechanism of the domestic elastic wire machine generally adopts the sliding friction transmission mode of the copper sleeve and the screw rod. In the production and application process, the parts are difficult to process, the precision requirements are often not met, and the transmission has no mechanical protection. , When there is no electrical control, it cannot reciprocate by itself, causing damage to the transmission mechanism and the transmitted parts, and the loss is huge. The transmission source is only driven by the addition and subtraction box of an ordinary motor, the control is fuzzy, and the accuracy of the traverse transmission is poor. ...
