For this reason, the utility model is by the following technical solutions: open-end spinning joint car positioning, it is characterized in that, described positioner comprises support, rocking arm, driving mechanism for rocker arm, upper sensor, lower sensor, location-plate, spring and piston rod, and described location-plate is fixedly installed on the touring guide rail of spinning machine main frame; Described support and driving mechanism for rocker arm are installed on the frame of described joint dolly; Described support is mainly connected to form by both sides sidewall and bottom, and described rocking arm middle part is fixed by the back shaft Support Position, the rocking arm rotation that can teeter centered by back shaft; Described frame bottom is provided with spring base, and the spring base center is provided with vertical through holes, and spring is flush-mounted on the spring base, and described piston rod passes through hole and spring center, and the spring upper end interfixes with piston rod; Described piston rod top is equipped with roller, and described location-plate bottom is provided with the groove of answering with pair of rollers; Described rocking arm rear end is connected with driving mechanism for rocker arm, and the rocking arm front end is connected with described piston rod; Described upper sensor, lower sensor become upper and lower setting to be installed on rack side wall.
As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic.
Described driving mechanism for rocker arm comprises motor, eccentric wheel and connecting rod, eccentric wheel is installed on machine shaft, the connecting rod two ends are connected with eccentric wheel, rocking arm end by pin respectively, motor rotarily drives the eccentric wheel rotation, eccentric wheel drives the rocking arm end by connecting rod and moves up and down, and drives rocking arm and teeters.
Described roller is bearing.
Offer mounting hole on the sidewall of described support, described upper sensor and lower sensor are installed on mounting hole, can adjust the up and down installation site of upper sensor and lower sensor.
When the joint dolly need to go the rounds to move to another spinning spindle position, the utility model motor-driven rocking arm rises on the rear end; the rocking arm front end is exerted pressure piston rod downwards; spring contraction; piston rod moves down, and the roller of piston rod part is deviate from the location-plate groove, after rocking arm triggers lower sensor; motor cuts out; restart motor when the joint dolly is touring to 50mm place, work ingot position, drive the rocking arm rear end and descend; rocking arm front end band rises with piston rod; the triggering upper sensor, motor cuts out, and by spring force roller is slipped in the location-plate groove; and limit roller by resilient support and do not skid off the location-plate groove, thereby finish pinpoint action.
Use the utility model can reach following beneficial effect: by automatic driving rocker-arm positioner location, the joint dolly can be navigated to the spinning spindle position that needs joint exactly, guarantee that Yarn connecting is smooth.
