Description
Technical field
The present invention relates to a kind of impact arrangement of clutch.
Background technology
This device can produce the impulsive force of circumferencial direction in each clutch process, import a little moment of torsion and rotatablely move, and this device will be accumulated output rotatablely moving than high pulling torque.This type device is mainly in screw thread loading and unloading in type electronic or pneumatic tool.
Existing impact arrangement of clutch comprises carriage, annular taping block and output shaft; And be employed in and penetrate two bearing pins on the carriage annular taping block is installed; For annular taping block can be installed and swing, also to directly upwards open a square orifice at carriage, axial pin shaft hole square orifice half hole therewith intersects.Traditional processing method processes this square orifice, also had the semicircle pin shaft hole of this square orifice to need more man-hour, and size is difficult to guarantee that percent defective is high; Reserve big surplus and process pin shaft hole earlier, with the broaching tool processing square opening of embarking on journey, cause trial-produce period long again, the broaching surplus makes that greatly broaching tool is long, and expense is too high; The carriage that processes is complex-shaped, after heat treatment distortion bigger, and produce stress at four jiaos of square orifices place, cause the carriage premature damage.
The inventor finds that through said structure is carried out careful research this causes owing to carrier structure is unreasonable, and carrier structure is complicated, causes processing difficulties.
Therefore, need a kind of new impact arrangement of clutch to address the above problem.
Summary of the invention
Goal of the invention: the object of the invention is complicated to impacting the arrangement of clutch carrier structure in the prior art, and the defective of processing difficulties provides impact arrangement of clutch a kind of simple in structure, easy to process.
Technical scheme: for realizing the foregoing invention purpose, the present invention can adopt following technical scheme:
A kind of impact arrangement of clutch comprises power output shaft, annular taping block and carriage, and it is inner that said output shaft and annular taping block are positioned at said carriage, and the part that said carriage holds said annular taping block and power output shaft is a drum shape.
Beneficial effect: compare with background technology, carrier structure of the present invention is simple, and processing, and job stability easily is high, and the life-span is long.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
See also Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, impact arrangement of clutch of the present invention, this impact arrangement of clutch comprises power output shaft 1, annular taping block 21,22 and carriage 3, power output shaft 1 is positioned at carriage 3 inside with annular taping block 21,22.Power output shaft 1 penetrates carriage 3, and the rotation of carriage 3 overlaps with the rotation of power output shaft 1.The part that carriage 3 holds annular taping block 21,22 and power output shaft 1 is a drum shape.Simple in structure, processing, and job stability easily is high, and the life-span is long.Carriage 3 is installed annular taping block 21,22 through two cylindrical bearing pins 51,52, and carriage 3 inner wall surface are provided with the arc groove that matches with cylindrical bearing pin 51,52.Two cylindrical bearing pins 51,52 cooperate with arc groove.
See also Fig. 5, shown in Figure 6; Has the groove that matches with cylindrical bearing pin 21,22 on the one side outer wall of annular taping block 21,22; Have the arc groove that becomes certain-length in the circumference on the opposite side outer wall on the other side, cylindrical bearing pin 21,22 is swung in the scope of arc groove with respect to annular taping block 21,22.At two cylindrical bearing pins 51, one or two annular taping blocks 21,22 are installed between 52; Annular taping block 21,22 can circumferentially freely swing along carriage 3 around one of them cylindrical bearing pin 51,52, and another cylindrical bearing pin 51,52 is used for hunting range with annular taping block 21,22 and is limited within the scope of arc groove that annular taping block becomes certain-length in the circumference.More than cylindrical bearing pin 51,52 and can be after cylindrical bearing pin 51,52 wearing and tearing in the design that the arc groove that cooperates with it is set on the carriage 3; Conveniently change; And cylindrical bearing pin 51,52 and carriage 3 can process respectively, can effectively guarantee machining accuracy.The working sections of power output shaft 1 is fan-shaped.
See also Fig. 3, shown in Figure 4, be provided with the recess 31 of stationary power output shaft 1 in the bottom of the drum shape part 30 of carriage 3, the bottom of recess 31 is provided with base.The base of its center dant 31 is provided with pod apertures 32, and is provided with the blocking device 33 that stops up pod apertures 32.Pod apertures 32 can derive the grease in the carriage 3.Top in the drum shape part 30 of carriage 3 is provided with seal cover 4, and seal cover 4 matches with the top of drum shape part 30, is fixed on the carriage 3 through cross recessed countersunk head sscrew.Wherein seal cover 4 is provided with the intercommunicating pore 41,42 that matches with cylindrical bearing pin 21,22.Can play the effect of holding cylindrical bearing pin 51,52.Through above-mentioned design; When impacting the arrangement of clutch running; Can in the seal cavity between annular taping block 21,22 and the carriage 3, add grease, thereby can greatly prolong the service life of carriage 3 and cylindrical bearing pin 51,52, and effectively improve the job stability that impacts arrangement of clutch.
Inventive principle: this device normally drives carriage 3 with motor in use, and carriage drives power output shaft 1 through annular taping block 21,22 and exports.Motor drives carriage 3 and rotates, and the rotation of carriage overlaps with the rotation of power output shaft 1; Two cylindrical bearing pins 51,52 directly are installed with one or two annular taping block 21,22 on the carriage 3; Annular taping block 21,22 is around one of them cylindrical bearing pin 51,52 swing, and another cylindrical bearing pin 51,52 is used for the hunting range of annular taping block 21,22 is limited in certain scope.The working sections of power output shaft is fan-shaped, power output shaft 1 penetrate carriage 3 and make its sector crosssection part in the axial direction just in time with the position consistency of annular taping block 21,22.The carriage tape rotating ring shape taping block of active rotation rotates around output shaft together; They with the sector crosssection of output shaft between the relative variation of position make the hammer periodic " disengaging " that goes in ring " engage " the scalloped surface part of output shaft again; " joint " all forms one-shot at every turn; Each moment propulsion power output shaft 1 passive doing and carriage rotation in the same way of impacting generation impacted the moment that produces and constantly built up to certain value along with impacting number of times.Carriage 3 (comprises annular taping block 21,22 and has bigger quality and radius, also just have bigger rotary inertia.This point can be widely used in the input of little moment of torsion with it, the occasion of high pulling torque output, and can realize the accumulation of moment of torsion.In the modern industrial, the operation of threaded fastener is indispensable, and workload is heavy.Also can this impact arrangement of clutch be applied in the screw threads for fastening kind tool and (comprise manual, electronic and pneumatic tool), can increase work efficiency greatly.
Impact arrangement of clutch of the present invention is simple in structure, processing easily, and stable performance, the life-span is long.It is unreasonable to have solved in the prior art carrier structure, complex structure, the problem of processing difficulties.
