Description

Multi-strand reed numerical control machine steel wire tension detects and rotary rope-twisting device

Technical field

The invention belongs to the multi-strand reed numerical control machine processing technique field, the steel wire tension of particularly numerical control multiply spring machining tool detects and rotary rope-twisting device.

Background technology

The multiply spring is widely used in the plant equipment of high frequency back and forth movement, and its life-span is helical spring 3～5 times of a same size tradition sub-thread.Multiply spring manufacturing technology is external nonnegotiable technology, is the emphasis problem of domestic research.Wangjiang Machine Building Factory is in the multiply spring machining tool of the independent development nineties, form with ordinary lathe, the multiply spring of different pitch and different rope distances adopts manual change gear to regulate, and steel wire tension is all regulated with workman's experience, and the first-time qualification rate of multiply spring has only about 20%.The digital control processing lathe of multi-strand springs of University Of Chongqing's independent development has not only had very big improvement aspect robotization, and precision also improved a lot, and simultaneously, the disposable qualification rate of multiply spring has also reached more than 80%.The steel wire tension of the multi-strand reed numerical control machine of University Of Chongqing's development detects and rotary rope-twisting device, be that 3～31 steel wires are twisted into 1～3 layer of coaxial cable wire, consist of the following components: (1) two servo deceleration motor, each one in skin and middle level are respectively applied for the exposed gear that drives outer and middle level.(2) two opposite opened gears, each is a pair of for skin and middle level.(3) steel wire box fixed mount, outer 18,12 in middle level is arranged on respectively on the steel wire box rotating disc equably.(4) rotary main shaft, outer, in and the main shaft of internal layer coaxial.Be used for steel wire guiding and cable wire and twist system.(5) steel wire case assembly, outer 18,12 in middle level, 1 of internal layer, middle level and outer field steel wire case assembly are installed in respectively on each support of corresponding steel wire box fixed mount.(6) wire tension controller, every steel wire is installed 1, has 31 tension controllers altogether, respectively by 31 air pressure transmitters controls and independent adjusting steel wire tensions.Their concrete structure and the course of work are: the servo deceleration motor drives the rotation of steel wire box rotating disc by the exposed gear transmission, and rotating disc drives the rotation of steel wire box fixed mount; The internal layer individual wire is installed a steel wire case assembly, and its runing rest is fixed on twists on the rope frame, and when pulling out steel wire, the steel wire case assembly only around its steel wire box axis rotation, does not have other additional movement; When middle level and cover wire wire vent, the steel wire case assembly also will lay out an axis and rotate freely (actual sense of rotation is opposite with stubborn rope axle sense of rotation) except that around the rotation of self axis with twist the revolution of rope axle; Each strand steel wire is equipped with independent air pressure automatic tension controller, each strand steel wire tension size is regulated separately, and the steel wire of internal layer tension controller does not rotate, and source of the gas is directly introduced, and middle level and cover wire tension controller have the composite rotating motion of both direction, and source of the gas is introduced by swivel adapter head.Steel wire case assembly fixed mount is installed on the rotating disc, and the steel wire box is installed on the steel wire box fixed mount, after each steel wire is pulled out from the steel wire case assembly, enters rotary main shaft again through tension controller, after buncher and twist into cable wire.The steel wire tension sensor is fixed between V-type bearing and the roller, in order to detect the tension force of steel wire.

The main weak point of this device is: steel wire was introduced the process complexity before this steel wire rotary rope-twisting device not only made processing, working strength is big, and make steel wire tortuous to having formed the buncher repeatedly from the steel wire box, in the main axis rotation process, steel wire is under the effect of many places friction force and can not follow its synchronous rotation closely, produce bigger moment of friction, thereby cause the bigger torsional deflection of steel wire, that have even plastic yield takes place, cause the twisting strength and the tensile strength of steel wire to reduce, have a strong impact on the workmanship of multiply spring product, reduced the serviceable life of multiply spring product.The main deficiency of its wire tension controller is: the distortion that not only is crushed under the effect of tension controller tension force of (1) steel wire, and the tension force of the existing steel wire of tension force that detects has steel wire box and the steel wire box frame gravity component at the steel wire axis direction again, is not actual steel wire tension.The direction of the tension force that (2) detects not with the steel wire axis in the same way, and have certain angle with steel wire, cause detecting inaccurate.(3) owing to driving steel wire box frame, rotates rotary main shaft at circumferencial direction, and gravity all the time vertically downward, so cause the sensor above equipment because the effect of gravity such as steel wire box makes the steel wire actual tension increase, on the contrary, the sensor below equipment is because the effect of gravity such as steel wire box makes the steel wire actual tension reduce.So, steel wire tension and actual steel wire tension that the steel wire tension pick-up unit of existing digital control processing lathe of multi-strand springs is detected differ too big, and per share steel wire tension is not of uniform size, thereby caused the internal tension of the per share steel wire of multiply spring produced can't guarantee unanimity at all, therefore, the stranded wire helical spring of coiling often produces the inconsistent phenomenon of degree of tightness, even reduce design accuracy, its rejection rate is also up to more than 80%.

Summary of the invention

The objective of the invention is provides a kind of multi-strand reed numerical control machine steel wire tension to detect and rotary rope-twisting device at the steel wire tension detection of existing multi-strand reed numerical control machine and the weak point of rotary rope-twisting device.The present invention from the steel wire wire vent to avoiding steel wire repeatedly tortuous and produce big moment of friction the buncher, and can detect the actual tension of per share steel wire accurately at diverse location, and have steel wire and introduce before simple to operate, simple structure, the processing steel wire and import that efficient height, working strength are little, steel wire is subjected to characteristics such as moment of friction is little, can reach per share steel wire tension unanimity, reduce the torsional deflection of steel wire, avoid steel wire generation plastic yield, the manufacturing qualification rate of raising multiply spring product and the purpose in the serviceable life of multiply spring.
