Description
Technical field:
The utility model relates to a kind of two stubborn locking devices of single head that bolt, locking nut requirement are tightened simultaneously that are used for, and belongs to the screw-threaded coupling device field.
Background technology:
In people's production work, have many structural requirement bolts to tighten by certain moment of torsion after, it is locked with certain moment of torsion with locking nut again.The locking of this type of situation generally all is to adopt by hand to carry out step by step by instrument, and the method for tightening is after with torque spanner bolt being tightened earlier, again with locking nut screwing.This kind method is inefficiency not only, poor reliability, and when tightening locking nut, bolt does not fixedly have additional rotation, and precision is tightened in influence.What abroad adopt is that two tightening machine are controlled respectively, carry out in two steps, and inconvenient operation, and also manufacturing cost is higher.
Summary of the invention:
The purpose of this utility model is: provide a kind of moment of torsion in accordance with regulations to tight a bolt simultaneously and locking nut, adopt a servomotor control, high efficiency, low cost of manufacture, reliable in action, and bolt and lock nut is at the fashionable two stubborn bolt devices of single head that buffer gear is all arranged of cover.
The utility model is to realize above-mentioned purpose by the following technical solutions:
The two stubborn bolt devices of this single head are made of motor, decelerator, axle a, axle b, axle c, clutch, gear a, gear b, gear c, gear d, gear e, gear f, gear g, brake, spring a, spring b, locking nut sleeve, bolt collar and casing, it is characterized in that: motor and decelerator are contained in the outside, middle part of casing, gear e is housed on the output shaft of decelerator, axle b is contained in the inboard, middle part of casing, and with the output shaft of decelerator on same axis, an a and an axle c are housed respectively on two side box bodies of axle b; Gear c is equipped with in the inner of axle b, and gear d is equipped with at the middle part, and locking nut sleeve and bolt collar are equipped with in the outer end of axle b; Gear a and gear b are equipped with in the middle part of axle a, and clutch is equipped with in the outside of gear a, and brake is equipped with in the outside of gear b; Gear f is equipped with at the middle part of axle c, and wherein an end is equipped with gear g.
Between axle b and the locking nut sleeve spring b is housed, between axle b and the bolt collar spring a is housed.
Gear e meshes with gear a and gear f respectively, gear b and gear c engagement, gear d and gear g engagement.
The utility model compared with prior art has following beneficial effect:
The two stubborn bolt devices of this single head can tight a bolt and locking nut simultaneously, and by a servomotor control, bolt is tightened the back and adopted brake to be fixed, and again with locking nut screwing, torque value is controlled by servomotor.Clutch, brake and motor continuous action are by the PLC programme-control, and gear transmission is adopted in the moment of torsion transmission.This installs high efficiency, and production cost is low, reliable in action, and bolt and locking nut are overlapping the fashionable buffer gear that all has.
Description of drawings:
Accompanying drawing is the structural representation of the two stubborn bolt devices of single head.
Among the figure: 1, reductor, 2, axle a, 3, clutch, 4, gear a, 5, gear b, 6, brake, 7, gear c, 8, axle b, 9, gear d, 10, spring a, 11, spring b, 12, the locking nut sleeve, 13, bolt collar, 14, gear e, 15, axle c, 16, gear f, 17, gear g, 18, casing, 19, motor.
The specific embodiment:
The two stubborn bolt devices of this single head are by motor 19, decelerator 1, axle a2, axle b8, axle c15, clutch 3, gear a4, gear b5, gear c7, gear d9, gear e14, gear f16, gear g17, brake 6, spring a10, spring b11, locking nut sleeve 12, bolt collar 13 and casing 18 constitute, motor 19 and decelerator 1 are contained in the outside, middle part of casing 18, gear e14 is housed on the output shaft of decelerator 1, axle b8 is contained in the inboard at casing 18 middle parts, and with the output shaft of decelerator 1 on same axis, an a2 and an axle c15 are housed respectively on two side box bodies 18 of axle b8; Gear c7 is equipped with in the inner of axle b8, and gear d9 is equipped with at the middle part, and locking nut sleeve 12 and bolt collar 13 are equipped with in the outer end of axle b8; Gear a4 and gear b5 are equipped with in the middle part of axle a2, and clutch 3 is equipped with in the outside of gear a4, and brake 6 is equipped with in the outside of gear b5; Gear f16 is equipped with at the middle part of axle c15, and wherein an end is equipped with gear g17.Between axle b8 and the locking nut sleeve 12 spring b11 is housed, between axle b8 and the bolt collar 13 spring a10 is housed.Gear e14 meshes with gear a4 and gear f16 respectively, gear b5 and gear c7 engagement, gear d9 and gear g17 engagement (referring to accompanying drawing).
