When existing gripper is picked up operation, it usually needs persistently gripper is applied active force, to ensure the pickup of object, increase the waste of production cost and the energy simultaneously.
Utility model content
For solving the problems referred to above, this utility model relates to a kind of self-locking gripper, and this device can pass through self-locking gripper so that need not also be able to ensure the pickup of object to the active force that applies that gripper is lasting.
For achieving the above object, the technical solution of the utility model is:
A kind of self-locking gripper, including piston rod, gripper and connecting rod, wherein, described gripper is made up of two gripper parts, and in the middle of each gripper part, there is support bar integrated with gripper part, all of gripper part is hinged by support bar end, the corresponding connecting rod of each gripper part, one end of all of connecting rod is hinged with the end of gripper part, and the other end of described connecting rod is hinged on the piston rod. Opening and Guan Bi of gripper is realized by push-and-pull piston rod, when connecting rod is in the straight line coincidence that all gripper part ends are formed, the junction of piston rod and connecting rod is located exactly at the dead-centre position in four-bar mechanism, thus realizing the self-locking of gripper, even if removing piston rod active force, picked article are without dropping.
Preferably, described piston rod is in the center of the straight line that two gripper part ends are formed. Can better realize auto-lock function.
A kind of self-locking gripper, including piston rod, gripper and connecting rod, wherein, described gripper is made up of the gripper part of more than three, and in the middle of each gripper part, there is support bar integrated with gripper part, all of gripper part is hinged by support bar end, the corresponding connecting rod of each gripper part, one end of all of connecting rod is hinged with the end of gripper part, and the other end of described connecting rod is hinged on the piston rod.When connecting rod is in the plane that all gripper part ends are formed, the junction of piston rod and connecting rod is located exactly at the dead-centre position in four-bar mechanism, thus realizing the self-locking of gripper.
Preferably, described piston rod is in the center of the plane that all gripper part ends are formed. Can better realize auto-lock function.
Preferably, inside the initial end of described gripper part, projection is set. Gripper is enable to easily pick up article.
It is further preferred that described lug surface arranges groove. Ensure the pickup article that gripper can be stable.
Preferably, described piston rod is connected with power set. Ensure that gripper can automatic Picking article.
Preferably, described gripper part being hinged in frame by support bar end.
It is further preferred that described frame be positioned at gripper part end formed plane or straight line place baffle plate is set. The thrust preventing piston rod is excessive, makes the junction of piston rod and connecting rod push away dead-centre position, and then ensures the stability of self-locking.
The beneficial effects of the utility model are:
1. this utility model simple in construction, low cost of manufacture, it is easy to realize promoting on a large scale, easy to clean;
2. this utility model has saved labour force, reduces production cost, improves work efficiency;
3. this utility model is simple to operate, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of embodiment 2
Wherein: 1. frame, 2. piston rod, 3. gripper part, 4. connecting rod, 5. support bar, 6. projection, 7. baffle plate.
Detailed description of the invention
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Embodiment 1
As shown in Figure 1, a kind of self-locking gripper, including piston rod 2, gripper and connecting rod 4, wherein, gripper is made up of two gripper parts 3, and in the middle of each gripper part 3, there is integrated with gripper part 3 and vertical with gripper part 3 support bar 5, gripper part 3 is hinged by support bar 5 end, the corresponding connecting rod 4 of each gripper part 3, one end of connecting rod 4 is hinged with the end of gripper part 3, the other end of connecting rod 4 is hinged on piston rod 2, and piston rod 2 is in the center of the straight line that two gripper part 3 ends are formed, and piston rod 2 is vertical with straight line. Opening and Guan Bi of gripper is realized, when connecting rod 4 is in the straight line coincidence that two gripper part 3 ends are formed, it is achieved the self-locking of gripper, even if removing piston rod 2 active force, picked article are without dropping by push-and-pull piston rod 2.
Projection 6 is set inside the initial end of gripper part 3. Projection 6 surface configuration groove.
Piston rod 2 is connected with power set.
Gripper part 3 is hinged in frame 1 by support bar 5 end.
Piston rod 2 pushes or pulls and can realize opening and Guan Bi of gripper. By the effect of frame 2 is realized moving integrally this self-locking gripper.
