Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, clear, complete description is carried out to the technical scheme of the utility model embodiment.
Shown in composition graphs 1 and Fig. 3, the pulling assembly of a kind of mechanical finger that the utility model discloses, tense-lax degree for each inter-module to mechanical finger regulates, and can by mechanical finger and other aids (as chute is pointed or aluminum strip etc.) with the use of.It comprises tension part 1, tension support 2 and tension pedestal 3, tension part 1 comprises tensioned screw 11, the tension axis of guide 12 and screws the tightening nut 13 on tensioned screw 11, as shown in Figure 5, be provided with the tension hole (not shown) run through for steel wire rope in tensioned screw 11, the outer surface of tensioned screw 11 is provided with locating slot 111.The tension axis of guide 12 is positioned at tensioned screw 11, is fixed with one through the steel wire rope of spring (not shown) by the mode of punching press in the tension axis of guide 12, when the tension axis of guide 12 is for coordinating at tightening nut 13 and tensioned screw 11 and straining steel wire rope or loosen, the movement of steel wire rope is play the guiding role.The top of the tension axis of guide 12 also fixes one for carrying out spacing jump ring 14 to tightening nut 13, splits away off when avoiding tightening nut 13 to rotate to tensioned screw 11 top.Tightening nut 13 can adopt wing nut.
Tension support 2 is positioned to be strained on pedestal 3 and is connected with spring, its global approximation is a cylinder, as shown in Figure 2, there is in it accepting hole 21 passed for tensioned screw 11, in this accepting hole 21, the locating slot 111 of corresponding tensioned screw 11 is provided with positioning key 22, and positioning key 22 stretches in locating slot 111 to limit the mutual rotation between tensioned screw 11 and tension support 2.Tension support 2 bottom sides has a support installing opening, and by this support installing opening, tension support 2 is connected with spring.
Tension pedestal 3 connects above-mentioned spring, spring one end screws a Spring screws 4 through after tension pedestal 3 in its end, this Spring screws 4 by spring retainer in tension pedestal 3 on, the structure that spring adopts Spring screws 4 spacing, can realize spring overall can along with the rotation of connector synchronous axial system, avoid spring excessively to affect the rotation of connector because of distortion, improve the rotation flexibility of connector.
Tension pedestal 3 coordinates with the connector (not shown) of mechanical finger, between them by snap-in structure (as groove and protruding embed cooperation mutually structure or teeth sting friction tight structure mutually with teeth) be connected.And tension pedestal 3 two side ends forms a First terrace 31 to the direction bending of tension support 2, this First terrace 31 just in time points the appear on the stage slide rail of scalariform of (not shown) with chute corresponding.
When adjustment tightness of steel wire rope is spent, tightening nut 13 is outwards outwarded winding from tensioned screw 11, then tensioned screw 4 drives steel wire rope to move to the direction of connector, steel wire rope is relaxed, on the contrary, by tightening nut 13 to the direction precession of tension support 2, then tensioned screw 11 drives steel wire rope to move to the direction away from connector, thus steel wire rope is tightened up, the position of each inter-module of mechanical finger is locked relatively.
Mechanical finger can be installed on chute finger by the structure of above-mentioned tension support 2 and tension pedestal 3, first steel wire rope is loosened, outwards pull tension support 2, it is made to be separated from tension pedestal 3, chute finger is snapped into after between tension support 2 and tension pedestal 3, after the slide rail pointed at chute by First terrace 31 slides to adjust mechanical finger to desired position, then strained by steel wire rope, each assembly making mechanical finger comprise chute finger is locked.
As preferred embodiment, as shown in Figure 4, also can be formed with a flank 23 at tension support 2 on the side near its top, directly mechanical finger can be installed on aluminum strip by this flank 23 and the cooperation of tension support 2 and use.Particularly, the bottom of flank 23 is formed with the second step face 24 relative with the First terrace 31 on tension pedestal 3, the corresponding existing machinery hand of distance between First terrace 31 with second step face 24 installs the width of aluminum strip, aluminum strip is clamped and is arranged between First terrace 31 and second step face 24, such mechanical finger do not need by chute finger etc. and other instruments with the use of, only need directly mechanical finger is installed on aluminum strip and use.
In this preferred embodiment, the bottom of tension support 2 also forms a projection 25, a groove (not shown) should be also set projection 25 faced by one end that tension pedestal 3 is relative with tension support 2, this projection 25 plays a similar fulcrum, when installing aluminum strip, tension support 2 rotates and makes this projection 25 be supported on tension pedestal 3, make there is distance between tension support 2 and tension pedestal 3 like this, and tension support 2 relative tension pedestal 3 entirety is skewed in one, form a clamping force between the two, aluminum strip is made to be fastened between two step surfaces, also make spring more stressed, mechanical finger not with aluminum strip with the use of time, then rotate tension support 2 and allow protruding 25 to be embedded in groove, the position of tension support 2 and tension pedestal 3 is positioned.
Technology contents of the present utility model and technical characteristic have disclosed as above; but those of ordinary skill in the art still may do all replacement and the modification that do not deviate from the utility model spirit based on teaching of the present utility model and announcement; therefore; the utility model protection domain should be not limited to the content that embodiment discloses; and various do not deviate from replacement of the present utility model and modification should be comprised, and contained by present patent application claim.
