Specific implementation mode
The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not conflicting
In the case of, the feature in the embodiments of the present invention and embodiment can be combined with each other.For sake of convenience, hereinafter such as
There are "upper", "lower", "left", "right" printed words, only indicates consistent with the upper and lower, left and right direction of attached drawing itself, not to structure
Play restriction effect.
As shown in Figure 1 and Figure 2, the gripper includes telescoping mechanism 1, basic arm 2, clamping jaw arm 3, drawstring 4 and torsional spring 5.
For the telescoping mechanism 1 including cylinder body 11 and along the telescopic rod 12 that the cylinder body 11 stretches, power resources are hydraulic pressure
Or gas.The both sides of the cylinder body 11 are equipped with fixed seat 13.
The basic arm 2 includes horizontally disposed horizontal arm 21, along two end of the horizontal arm and same lateral two outside
Adjutage 22, sliding slot 23 and the pulley 24 extended is tilted, the telescopic rod 12 is set to the other side of horizontal arm 21 and vertically supports
It is connected to the horizontal arm 21, i.e. telescopic rod 12 can be along 21 stretching motion of horizontal arm.The sliding slot 23 is arranged in the adjutage 22
It is interior, and close on setting inside the gripper.The pulley 24 includes pedestal 241 and is articulated with the pedestal 241 and can be along base
The wheel portion 242 of 241 rotation of seat, the pedestal 241, which is set to, to be closed on the runner wall inside gripper.
The quantity of the clamping jaw arm 3 is two, is respectively pivoted to the one end of adjutage 22 far from horizontal arm 21.
As shown in Fig. 2, the basic arm 1 includes first step slot 25, the clamping jaw arm 3 includes second step slot 31 and edge
The second step slot 31 bends the third step groove 32 of extension, the bottom plate and second step slot 31 of the first step slot 25 again
Bottom plate be pivotally connected by drive-connecting shaft 33.
The torsional spring 5 be sheathed on the drive-connecting shaft 33 and both sides abut respectively first step slot 25 side wall and second
The side wall of rank slot 31.
As shown in Figure 1, the bottom plate of the third step groove 32 is equipped with pulling seat 34.The pulling seat 34 is in the third step
The inside setting of gripper is closed on the bottom plate of slot 32.
As shown in Fig. 2, the pulling seat 34 includes 341 He of small diameter portion being stacked along the bottom plate of the third step groove 32
Large-diameter portion 342.
The drawstring 4 of gripper side penetrates through the sliding slot 23, and one end is connect with fixed seat 13, the other end and pulling seat 34
Small diameter portion 341 connect, by the stretching of cylinder body 12, movement of contract, the drive pulling adjutage 22 of drawstring 4 outwardly or inwardly rotates, by
The action that this realization is grabbed, put.The mounting means of gripper both sides drawstring is identical.When drawstring 4 pulls small diameter portion 341 to act, because big
The diameter in diameter portion 342 is more than small diameter portion, can prevent from being detached from pulling seat 34 when 4 pulling action of drawstring.The wheel portion 242 and drawstring
On the one hand 4 tangent contacts, i.e. drawstring 4 keep transmitting with the best pulling position of pulling seat 4, pulling force when pulling by wheel portion 242
Property it is more preferable, on the other hand reduce frictional force when pulling, wheel portion 242 drives by drawstring 4 and roll together, pulls more laborsaving.
The clamping jaw arm 3 further includes the grip block 35 for being set to its end and being arranged towards inside, and the grip block 35 is rubber
Material is made, and increases frictional force when crawl, improves crawl effect.
In the present embodiment, the length of the clamping jaw arm 3 is more than the length of adjutage 22, increases the ductility of adjutage 22
And extending range, expand the range of grippers size, applicability is wider.
In the present embodiment, the small diameter portion 341 is made of PVC material, effectively reduces its mill generated between drawstring 4
Damage extends the service life of drawstring 4.
As described in Figure 3, telescoping mechanism 1 extends, and cylinder body 11 is far from horizontal arm 21, the action for driving drawstring 4 to pull back,
The other end of drawstring 4 drives clamping jaw arm 3 to turning round inside gripper by pulling seat 34, and the clamping jaw arm 3 of both sides turns round simultaneously, until
Until grabbing object to be grabbed.
When needing to discharge crawl object, telescoping mechanism 1 bounces back, and drawstring 4 no longer holds pulling force to pulling seat 34, in torsional spring 5
Under effect, the clamping jaw arm 3 returns to original state.
Compared with the relevant technologies, gripper provided by the utility model pulls end to execute clamping jaw realization and grabs by steel wire rope
It takes, largely ensure that effective transmission of end implementation capacity, and crawl position is accurate, simple in structure, reliability is high, when reset
It is restorative good.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other relevant technical fields, are equally included in the patent within the scope of the utility model.
