Abstract
The invention relates to an axial force transfer device. An input pull rod is arranged into the input end of a connecting sleeve; then a steel ball is arranged in a through hole in the connecting sleeve; next, assembling of a locking sleeve and the connecting sleeve is completed; the steel ball is sealed in a closed region formed by the locking sleeve, the connecting sleeve and the input pull rod. In the scheme, the steel ball is used as a transfer medium of a force and motion and enables the locking sleeve and the input pull rod to flexibly and relatively rotate; finally, an output pull rod is arranged. The device has a compact and light structure; the end part of the input pull rod is matched with the steel ball and the steel ball can rotate in the closed region, and thus, the axes of the two pull rods can be shifted or inclined a little and still can be normally used and the requirement of the device for assembling and processing accuracy is greatly reduced.
Description
Technical field
The invention belongs to a kind of force-transmitting device in mechanical transmission, a kind of transmitting axle force device of specific design.
Background technique
At present, along with the quickening of process of industrialization, industrial automatization is more and more higher.Among production and processing, automated machine equipment starts to come into operation in a large number.Wherein, commonly automation equipment is mechanism hand.Mechanism hand, according to the difference of application target, can connect different process equipments on a robotic arm, reach different processing requests.Under the processing conditions that some are special, need the push-and-pull campaign rotation of mechanism hand input end and push-and-pull compound motion being converted into output terminal, namely eliminate rotation wherein completely, and the integrity of total will be ensured, the normal use of mechanism hand can not be affected.
Summary of the invention
The object of the present invention is to provide a kind of transmitting axle force device, the rotation of mechanism hand input end and push-and-pull compound motion can be converted into the push-and-pull campaign of output terminal, reach usage requirement.
For achieving the above object, technological scheme of the present invention is: transmitting axle force device, comprise input pull bar and export pull bar, described input pull bar is connected by connecting sleeve with output pull bar, described connecting sleeve is divided into input end and output terminal, described input end is provided with a circumferential annular groove, and described annular groove inner circumferential is evenly equipped with through hole, is provided with steel ball in described through hole; Described connecting sleeve is arranged with lock sleeve, and described lock sleeve is installed on input end, and the inwall of described lock sleeve contacts with steel ball and compresses steel ball; The termination that described input pull bar is connected with connecting sleeve is provided with annular slot, and the described steel ball part stretched in through hole is stuck in the annular slot of input pull bar.
When adopting technique scheme, input pull bar is loaded the input end of connecting sleeve, then load steel ball in the through hole on connecting sleeve, afterwards lock sleeve and connecting sleeve are completed assembling, steel ball is enclosed among the closed area that is made up of lock sleeve, connecting sleeve and input pull bar.Steel ball is as the transmission medium of force and motion in this programme, and lock sleeve and input pull bar can be relatively rotated neatly, are finally install to export pull bar.The advantages of compact and light structure of this device, because the end and steel ball that input pull bar coordinate, steel ball can rotate in closed area, and therefore the axis of two pull bars can have a small amount of skew or inclination, still normally can use, greatly reduce device to assembling and the requirement of machining accuracy.
Further, described connecting sleeve is provided with ending rotator, and described ending rotator is positioned at output terminal, and described ending rotator is provided with spline pin; The output terminal of described connecting sleeve offers axial spline groove, described spline pin inserts in spline groove.Ending rotator can overcome the rolling friction torque transmitted by steel ball completely, thus the seal ring of output pull bar is not rotated.So just can improve the working life of seal ring.
Further, the input end of described connecting sleeve is provided with annular boss, the end face of described lock sleeve and the end contact of annular boss.Above-mentioned design can place in use lock sleeve from slippage connecting sleeve.
Further, the end face inner circle of described lock sleeve is provided with chamfering.Above-mentioned design can be played between lock sleeve and steel ball when installing lock sleeve and install leading role, is convenient to the installation of lock sleeve.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of transmitting axle force device embodiment of the present invention;
Fig. 2 be in Fig. 1 A-A to sectional structure schematic diagram.
Embodiment
As depicted in figs. 1 and 2, transmitting axle force device of the present invention, comprises input pull bar 1 and exports pull bar 2, and input pull bar 1 is connected by connecting sleeve 3 with output pull bar 2.Connecting sleeve 3 is divided into input end and output terminal, and wherein, input end is connected with input pull bar 1, and output terminal is connected with output pull bar 2.The input end of connecting sleeve 3 has a circumferential annular groove, and annular groove inner circumferential is evenly equipped with through hole, is provided with steel ball 4 in through hole.The termination be connected with connecting sleeve 3 at input pull bar 1 also has annular slot, and steel ball 4 part stretched in through hole is stuck in the annular slot of input pull bar 1.In addition, on connecting sleeve 3, cover has lock sleeve 5 that is fixing and locking steel ball 4, and lock sleeve 5 is installed on the input end of connecting sleeve 3, and the end contact of the annular boss of the end face of lock sleeve 5 and connecting sleeve 3 end.The inwall of lock sleeve 5 contacts with steel ball 4 and compresses steel ball 4.Be in actual demand, connecting sleeve 3 is provided with ending rotator 6, ending rotator 6 is positioned at the output terminal of connecting sleeve 3, and ending rotator 6 is provided with spline pin; The output terminal of connecting sleeve 3 offers axial spline groove, spline pin inserts in spline groove.Ending rotator 6 can overcome the rolling friction torque transmitted by steel ball 4 completely, thus the seal ring of output pull bar 2 is not rotated.So just can improve the working life of seal ring.
Said apparatus in use, input pull bar 1 is loaded the input end of connecting sleeve 3, then load steel ball in the through hole on connecting sleeve 3, afterwards lock sleeve 5 and connecting sleeve 3 are completed assembling, steel ball 4 is enclosed among the closed area that is made up of lock sleeve 5, connecting sleeve 4 and input pull bar 1.Steel ball 4 is as the transmission medium of force and motion in this programme, and lock sleeve 5 and input pull bar 1 can be relatively rotated neatly, are finally install to export pull bar 2.The advantages of compact and light structure of this device, because the end and steel ball 4 that input pull bar 1 coordinate, steel ball 4 can rotate in closed area, and therefore the axis of two pull bars can have a small amount of skew or inclination, still normally can use, greatly reduce device to assembling and the requirement of machining accuracy.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
