Abstract

The invention discloses a grabhook and a grabhook opening and closing method. The grabhook comprises a rack, a clamping jaw device and a clamping jaw opening and closing drive device. A clamping jaw is unfolded and folded through matching of a rotating cam, a pressure plate and a pressure spring, and meanwhile the grabbing and autoroatation effects can be achieved just by two motors. The grabhook is simple in structure, low in cost, reliable to operate, suitable for occasions where test tubes are required to be moved frequently and capable of bringing better operation benefits.

Description

technical field [0001] The invention relates to a claw and a method for opening and closing the claw. Background technique [0002] With the improvement of the degree of automation in the industry, a large number of repetitive and simple tasks have begun to be completed by machines. However, due to the complex structure of some mechanical devices, the corresponding procurement costs are relatively high. rising labor costs. In workplaces such as laboratories and hospitals, it is necessary to move the manipulator used for the test tube. Due to the small size and light weight of the test tube itself, there is no particularly high requirement for the grasping strength of the manipulator. If a general manipulator structure is used to perform the test This operation may lead to an increase in the execution cost of this simple work, which is not good for the operation. Contents of the invention [0003] In order to solve the situation that the current manipulator is complicated...
