The specific embodiment
each component working principle of the present utility model is as follows:
A kind of plug screw-on machine is twisted and auxiliary machinery device in advance, mainly comprises: pull bar driving mechanism, supporting carrier roller mechanism, clamping transfer mechanism, rotary support mechanism, double bracket roller mechanism, pre-mechanism, backgauge frame and the base of twisting of rotation.Whole device mainly is divided into three parts: the entrance mechanism assembly, twist mechanism assembly and exit mechanism assembly in advance.Each several part all is fixed on base.Its function is that active section, extension and the gripping section screw thread that will form plug automatically completes make-up and twist in advance and coordinates and stubbornly connect that main frame is stubborn to be connect and unclamp work.The entrance mechanism assembly is responsible for a plug extension and is transferred into twisting and connect position of rotation and carry out center adjustment and rotary support, can make this section rotate freely under stressed effect; The exit mechanism assembly is responsible for a plug active section and is transferred into twisting and connect fixed position and to carry out corresponding center adjustment and carrying roller supports, and this section plug can not be rotated freely; The pre-responsible stubborn position rotary support that connects of mechanism assembly of twisting reaches the pre-work of twisting.In twisting termination process, the rotary support of its arrival end, the carrying roller of the port of export support, middle pre-rotary support of twisting assembly is twisted and connect main frame on same central horizontal line, and internal thread and external screw thread are consistent at make-up and Ning Jieshi center.First turn in advance work after plug centering, by interior button and at the uniform velocity soft being connected of outer button, twist again the work of connecing after putting in place.The above object is to avoid because of the wound button problem due to button partially.At the entrance and exit mechanism assembly, place is equipped with backgauge frame and fender bracket, to prevent plug, in the process of lifting and decline, deflects away from, skids off roller-way.Whole Equipment is controlled the sensor in each mechanism by PLC, can realize that full-automatic, semi-automatic electric is controlled and rational manual intervention function.
Described entrance mechanism assembly comprises that 4 supporting carrier roller mechanisms are linked into an integrated entity by the pull bar driving mechanism; Pull bar driving mechanism decelerating through motor unit drives the screw mandrel of screw lift to move forward and backward, thereby pulls pull bar to move forward and backward.The hinged drive connecting lever of the connecting lever of pull bar driving mechanism and supporting carrier roller mechanism swings, and the backing roll on it swings up and down along its supporting seat, thereby regulates the center of different-diameter plug, to meet, twists the height needs that connect main frame.The effect that is arranged on the clamping transfer mechanism on base is plug to be transferred to twist to connect (unscrewing) position and to twist connect operation and complete backed off after random and twist and connect (unscrewing) position.Under the effect that pinches fluid cylinder, two pinch rolls gradually near final laminating plug and apply certain pressure, drive two pinch rolls to rotate by two-stage turbine worm speed-down unit from the plug both sides.Drive plug and do axially-movable under the effect of frictional force.Be arranged on base the effect of rotary support mechanism and be twisting while connecing (unscrewing) operation, support the plug extension, and rotate with the plug extension.Due to the diameter of mandrel difference, so the backing roll height is also inconsistent.This mechanism drives screw lift to drive backing roll rising (decline) motion by the electric speed reducing unit.When backing roll, with after mandrel surface fully contacts, elevating mechanism stops automatically.
The described pre-mechanism assembly of twisting is comprised of double bracket roller mechanism and the pre-mechanism of twisting of rotation.Wherein the double bracket roller mechanism is comprised of one group of conveying carrier roller and two groups of rotary carrier rollers.Twisting while connecing (unscrewing) operation, two groups of rotary carrier rollers in its mechanism are done ascending motion by the thrust of fluid cylinder, support the plug extension, and rotate with the plug extension.With the rotary support mechanism in described entrance mechanism assembly, plug is formed to 2 supports, synchronization action, complete to twist connecing (unscrewing) operation with the centre-height that coordinates main frame; Supporting carrier roller is done descending motion under the pulling force of fluid cylinder, avoids contacting with plug, interferes; After operation, rotary carrier roller descends, and conveying carrier roller rises, and plug can carry out transfer movement.The pre-effect of twisting mechanism of rotation is that two sections of the plugs of separation are twisted and are connected together.The effect lower swing arm running roller of tension fluid cylinder from top to bottom gradually near and the plug apply certain pressure of fitting, the driving swing arm running roller by hydraulic motor rotates.Drive one section rotation together of plug under the effect of frictional force, thereby be threaded connection the pre-operation of twisting.
Described exit mechanism assembly comprises that 7 supporting carrier roller mechanisms are linked into an integrated entity by the pull bar driving mechanism; Pull bar driving mechanism decelerating through motor unit drives the screw mandrel of screw lift to move forward and backward, thereby pulls pull bar to move forward and backward.The hinged drive connecting lever of the connecting lever of pull bar and supporting carrier roller mechanism swings, and the backing roll on it swings up and down along its supporting seat.The effect that is arranged on the clamping transfer mechanism on base is plug to be transferred to twist to connect (unscrewing) position and to twist connect operation and complete backed off after random and twist and connect (unscrewing) position.Its function is identical with the clamping transfer mechanism of entrance mechanism assembly.
All hinged lubricated all adopt dry oil lubrication or the self-lubricating plain bearing of whole device.
