Abstract
The utility model relates to a wrench for boosting and limiting torque, composed of a primary booster mechanism and a secondary booster mechanism. The utility model is characterized in that the primary booster mechanism can drive a hexagonal socket to rotate by a gear shaft which drives a planetary gear to rotate on the inner teeth of an outer sleeve, and a support abutting block is arranged on the outer side of the hexagonal sleeve; the forcing end of the primary booster mechanism is connected with a square-head socket or the output end of a square sleeve of the secondary booster mechanism; the secondary booster mechanism is composed of a planetary gear booster mechanism, an adjustable torque limiting device and a controllable torque limiting handle, wherein, the controllable torque limiting handle and the adjustable torque limiting device are arranged at the end head of a shell of the secondary booster mechanism, an eccentric circular-arc block is fixed on the controllable torque limiting handle, and a torque limiting head of the adjustable torque limiting device is abutted on the circular-arc top surface of the circular-arc block.
Description
The utility model relates to instrument, particularly a kind of can be laborsaving and can limit and try hard to avoid the instrument of exempting from and the impaired Wrench providing for torque amplification of workpiece.
Have the reinforcement spanner in the prior art, it has following weak point:
1. reinforcement is big inadequately, the automotive tyre nut big to the nut more than the M20, particularly coupling mechanism force, and installation and removal are effort quite;
2. its external tooth cover that has will have the fixing strong point to use, and using has limitation;
3. because the device of unlimited power, easy breaking-up instrument and workpiece during locking.
The purpose of this utility model is: provide a kind of have increase, limit the power function, the Wrench providing for torque amplification of laborsaving and don't damage instrument and workpiece.
The purpose of this utility model is to realize by such technical scheme, it is a kind of Wrench providing for torque amplification, constitute by one-level force-increasing mechanism and secondary force-increasing mechanism, it is characterized in that: the one-level force-increasing mechanism drives three capable internal tooth rotations that add powershift gear at one-level reinforcement overcoat of star by gear shaft, the tooth axle that adds powershift gear is installed in it is rotated with adding powershift gear, has in the outside of interior Hexagonal jacket to prop up to be supported by piece; The reinforcing end of one-level force-increasing mechanism is the axle head square toes of gear shaft, be connected with tooth rest side's cover output of square toes sleeve or secondary force-increasing mechanism, the secondary force-increasing mechanism is by the capable gear grooved force mechanisms of star, adjustable force limiting device and controllable type limit power handgrip constitute, wherein the internal tooth of secondary force-increasing mechanism shell drives the capable gear rotation of the star that is installed on the tooth rest, pass through gear shaft by it, the cover rotation of driven gear frame side, controllable type limit power handgrip and adjustable force limiting device are installed in the termination of secondary force-increasing mechanism shell, be fixed with the eccentric arc piece on the controlled or limit power handgrip, the limit power crown of adjustable force limiting device is at the circular arc end face of circular arc piece.
Said structure of the present utility model can further specify by the non-limiting embodiment that accompanying drawing provides.
Of the present utility model have a following accompanying drawing:
Accompanying drawing 1 is a structure cutaway view of the present utility model;
Accompanying drawing 2 is a left view of the present utility model.
Referring to accompanying drawing: the one-level force-increasing mechanism of Wrench providing for torque amplification drives three capable internal tooth rotations that add powershift gears 6 at one-level reinforcement overcoat 4 of stars by gear shaft 7 among the figure, the tooth axle 5 that adds powershift gear is installed in it is rotated with adding powershift gear, has in the outside of interior Hexagonal jacket to prop up to be supported by piece 1; The reinforcing end of one-level force-increasing mechanism is the axle head square toes of gear shaft, be connected with the tooth rest 11 sides cover output of square toes sleeve or secondary force-increasing mechanism, the secondary force-increasing mechanism is by the capable gear force-increasing mechanism of star, adjustable force limiting device 14 and controllable type limit power handgrip 15 constitute, wherein the internal tooth of secondary force-increasing mechanism shell 10 drives capable gear 13 rotations of the star that is installed on the tooth rest 11, pass through gear shaft 12 by it, driven gear frame 11 sides overlap rotation, controllable type limit power handgrip 15 and adjustable force limiting device 14 are installed in the termination of secondary force-increasing mechanism shell 10, be fixed with eccentric arc piece 9 on the controllable type limit power handgrip, the limit power of adjustable force limiting device 8 withstands on the circular arc end face of circular arc piece 9.
Adjustable force limiting device 14 is by compression spring, adjustable bolt in the utility model, and the limit power head of spring front end, locking nut and housing are formed.
Operation principle of the present utility model is such: according to big or small with whether needs are limit power to the reinforcing of workpiece, select use one-level or secondary or a secondary to be used in combination.For example, when using the one-level force-increasing mechanism, load onto the outer-hexagonal nut sleeve or the sleeve of different size, connect the square toes sleeve at the other end again, just can load and unload the nut of different size at an end of interior Hexagonal jacket 2.When needs limit power, according to the difference of the big or small nut check power of difference, the degree of tightness of regulating the compression spring of adjustable force limiting device 14 realizes.When operation controllable type limit power handgrip 15, when the eccentric arc piece rotates to the both sides of circular arc piece along with shell 10, promptly be the limit point of limit power, handle is thrown off automatically, has played the effect of limitting try hard to keep nurse's tool and workpiece.
The utility model is owing to described structure has that volume is small and exquisite, compact, easy to carry, disassembly and assembly advantage easily, uses not only laborsavingly but also do not damage instrument and workpiece, is with car, reaches the ideal tools of other field indispensability at random.
