Background technique
Hyundai electronics, precision component assembling or process in, be often related to clamping to precision component and keep
Or part positioning etc. operates, both ends, which clamp unilateral clamp relatively, in clamping device has more accurate, more firm feature.Existing skill
In art, two sides clamping device mostly uses the mode of double drive, and there is clamping time differences to cause precision inadequate for dual-driving-mode
The problem of, and equipment design is relatively complicated.
Utility model content
In order to overcome the deficiencies of the prior art, the utility model provides a kind of both ends clamping device, by that will control two folders
Two connecting rods of pawl pinching action are arranged on same cantilever, are driven with the same driving cylinder to cantilever, solve double
The problem for driving precision inadequate, equipment design simple operations conveniently, and clamping efficiency is high.
To achieve the above object, the technical solution adopted in the utility model is as follows: a kind of both ends clamping device, including driving
Cylinder, cantilever and clamping jaw, driving cylinder is interior to be equipped with the oscillating bearing to move reciprocatingly in driving cylinder, and oscillating bearing one end connects
Driving cylinder other end connecting cantilever is connect, cantilever two sides are equipped with two connecting rods that one is long and the other is short, and long connecting rod is in far driving cylinder one
Side, short connecting rod the tie point and cantilever of cantilever and two connecting rods and drive the tie point of cylinder common in closely driving cylinder side
Three vertex of triangle, connecting rod one end connecting cantilever are constituted, the other end connects clamping jaw, and Workpiece carrier is equipped between clamping jaw and clamping jaw
Platform, connecting rod are rigid link.
Further, cantilever is triangle cantilever.
Further, Workpiece carrier platform has support frame.
Further, cantilever is fixed on the support frame by fixed link.
Further, cylinder, oscillating bearing and support frame is driven to have pedestal.
From the above description of the utility model, it can be seen, compared with prior art, a kind of both ends provided by the utility model
Clamping device has following several advantages: 1, more smart by the way of the utility model is clamped using both ends relative to unilateral clamping device
It is quasi-, more firm.2, two connecting rods for controlling two jaw actions connect same cantilever, are driven with a driving cylinder to cantilever
It is dynamic, it realizes the high level of synchronization of two jaw actions, solves the problems, such as that precision caused by the double drive time difference is inadequate.3, structure
Design is simple, easy to operate, clamps high-efficient.

Fig. 3 is the cross-sectional view of the structure of one clamping jaw clamped condition of the utility model specific embodiment.
Detailed description of the invention: 1- drives cylinder, 2- cantilever, 3- clamping jaw, 4- oscillating bearing, 5- long connecting rod, 6- short connecting rod, 7- workpiece
Plummer, 8- support frame, 9- fixed link, 10- pedestal.
Specific embodiment
Below by way of specific embodiment, the utility model will be further described.
As shown in Figure 1, a kind of both ends clamping device, including driving cylinder 1, cantilever 2 and clamping jaw 3, it drives in cylinder 1 and is equipped with
The oscillating bearing 4 to move reciprocatingly in driving cylinder 1,4 one end of oscillating bearing connection driving 1 other end connecting cantilever 2 of cylinder,
2 two sides of cantilever are equipped with two connecting rods (5,6) that one is long and the other is short, and long connecting rod 5 is closely driving in far driving 1 side of cylinder, short connecting rod 6
The tie point and cantilever 2 of 1 side of cylinder, cantilever 2 and two connecting rods (5,6) and the tie point of driving cylinder 1 collectively form triangle
Three vertex of shape, connecting rod (5,6) one end connecting cantilever 2, the other end connect clamping jaw 3, hold between clamping jaw 3 and clamping jaw 3 equipped with workpiece
Microscope carrier 7, connecting rod (5,6) are rigid link.
Specific embodiment one:
As shown in Figure 1, on the basis of the above, in this specific embodiment: cantilever 2 is triangle cantilever.
Workpiece carrier platform 7 has support frame 8, and cantilever 2 is fixed on support frame 8 by fixed link 9, and driving cylinder 1 closes
Bearings 4 and support frame 8 have pedestal 10.
Working principle:
As shown in Fig. 2, workpiece is placed on Workpiece carrier platform 7, when both ends clamping device is in relaxed state, joint
Bearing 4 protrudes into most deep in driving cylinder 1, be limited to the length limitation of two rigid links (5,6), remote 1 side of cylinder that drives
The tie point of long connecting rod 5 and cantilever 2 is in partial below, and the short connecting rod 6 of nearly driving 1 side of cylinder and the tie point of cantilever 2 are on the upper side
The tie point of side, two connecting rods (5,6) and cantilever 2 is in its maximum distance with clamping jaw.
As shown in figure 3, driving cylinder 1 drives oscillating bearing 4 to move out, oscillating bearing 4 is by cantilever 2 along oscillating bearing 4
Direction is released, and the length for being limited to two rigid links (5,6) and clamping jaw 3 is fixed, the tie point of long connecting rod 5 and cantilever 2 by
Gradually rise, tie point moves closer to clamping jaw 3, and long connecting rod 5 squeezes clamping jaw 3 to push the tightening of clamping jaw 3, at the same time, short connecting rod 6
It is gradually reduced with the tie point of cantilever 2, tie point also moves closer to clamping jaw 3, and short connecting rod 6 squeezes clamping jaw 3 to push clamping jaw 3 to receive
Tightly, realize that both ends clamping jaw 3 tightens the workpiece clamped on Workpiece carrier platform 7 simultaneously.
It above are only the preferred embodiment of the utility model, but the design concept of the utility model is not limited to
This, all non-essential modifications to the present invention made by this concept should belong to infringement scope of protection of the utility model
Behavior.
