Abstract
The utility model discloses a clamping device which comprises a substrate, at least two pawl body connecting rods and a driving member. The pawl body connecting rods are inserted into the substrate. The top of each pawl body connecting rod is driven by the driving member to move toward the same point in a reciprocating manner. The driving member drives the top of each pawl body connecting rod inserted into the substrate and makes the pawl body connecting rods to move toward the same point in a reciprocating manner, such that the top of each pawl body connecting rod pulls back or is unfolded. If the top of each pawl body connecting rod pulls back, a workpiece is clamped, and if the top of each pawl body connecting rod is unfolded, the workpiece is loosened. A worker only needs to control on and off of the driving member to clamp or loosen a workpiece. Therefore, the clamping device is labor-saving, time-saving, convenient and fast.

In some embodiments, cleft hand can be hinged with substrate.Thus, when actuator drive link is moved away from central point respectively, connecting rod can drive cleft hand hypercentre point motion (contraction) respectively, and when actuator drive link is moved towards central point respectively, connecting rod can drive cleft hand respectively away from central point motion (opening).
In some embodiments, can also comprise at least two connecting rods, one end of connecting rod and connecting rod is hinged, and the other end and the actuator of connecting rod are hinged.Thus, actuator drives the cleft hand of corpus unguis connecting rod shrink or open by connecting rod, thereby realizes the clamping of workpiece or unclamp.
In some embodiments, the quantity of connecting rod can be three.Thus, actuator drives the cleft hand of corpus unguis connecting rod shrink or open by three connecting rods.
In some embodiments, the quantity of corpus unguis connecting rod can be three.Thus, the cleft hand of three corpus unguis connecting rods shrinks and workpiece can be clamped securely towards central point respectively.
In some embodiments, can be provided with Y type groove on substrate, three corpus unguis connecting rods intert in Y type groove, and cleft hand stretches out the upper surface of substrate, and connecting rod stretches out the lower surface of substrate.Thus, Y type groove can limit the reciprocating motion of corpus unguis connecting rod.
In some embodiments, actuator can be oil cylinder.Thus, the flexible cleft hand that can realize corpus unguis connecting rod by piston in oil cylinder clamps or unclamps.
In some embodiments, can also comprise base plate and at least one joint pin, substrate is connected with base plate by joint pin, and actuator is located on base plate.Thus, can improve resistance to overturning and the positioning precision of clamping device.
In some embodiments, the number of joint pin can be three, and substrate is connected with base plate by three joint pins.Thus, substrate is connected stability and the positioning precision that can improve substrate upper clawer body connecting rod with base plate by three joint pins.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 to Fig. 3 has schematically shown the structure of the clamping device of a kind of embodiment of the utility model.
As shown in Figure 1 to Figure 3, clamping device, comprises substrate 1, corpus unguis connecting rod 2 and actuator 3.In addition, clamping device can also comprise connecting rod 4, base plate 5, joint pin 6, axle 7 and latch 8.
On substrate 1 side, be drilled with three holes 12, the upper surface mold of substrate 1 forms Y-shaped groove 11.
Corpus unguis connecting rod 2 comprises cleft hand 21 and connecting rod 22.
Connecting rod 22 is positioned at the below of cleft hand 21, forms an angle that is less than 180 degree between cleft hand 21 and connecting rod 22.In the present embodiment, cleft hand 21 is connected with connecting rod 22 one, and the angle that cleft hand 21 and connecting rod 22 form is 150 degree.In other embodiments, connecting rod 22 also can be welded on the below of cleft hand 21, and the angle that cleft hand 21 and connecting rod 22 form also can change to the angle that other is less than 180 degree as required.
In the present embodiment, the quantity of corpus unguis connecting rod 2 is three, and the quantity of connecting rod 4 is three, and the quantity of axle 7 is three, and three corpus unguis connecting rods 2 can very firmly clamp workpiece location.In other embodiments, the quantity of corpus unguis connecting rod 2, connecting rod 4 and axle 7 also can be two or four.
Corpus unguis connecting rod 2 interts in the Y-shaped groove 11 of substrate 1, is drilled with through hole 211 on cleft hand 21, and axle 7 is successively through hole 12 and through hole 211, and each cleft hand 21 is hinged by axle 7 and substrate 1.
The connecting rod 22 of each corpus unguis connecting rod 2 bottom is hinged with one end of connecting rod 4 by latch 8, the other end of connecting rod 4 is hinged by bolt and actuator 3, be that actuator 3 is hinged with three connecting rods 22 respectively by three connecting rods 4, thus realize three corpus unguis connecting rods 2 cleft hand 21 contraction or unclamp.
