Mechanical paw clamping force detection device

Abstract

The invention discloses a mechanical paw clamping force detection device. The mechanical paw clamping force detection device is characterized by comprising a base, a supporting part, a support and a force detection part, wherein the supporting part is vertically and fixedly connected with the base, and the supporting part comprises a first supporting part and a second supporting part which are arranged in parallel; the support is arranged between the first supporting part and the second supporting part; and the force detection part is arranged on the support. The detection device has the advantages of being simple in structure and easy to use, and capable of being used for detecting the clamping force of mechanical paws in different forms and the like.

Description

Technical field [0001] The invention relates to the field of detection, in particular to a device for detecting the clamping force of a manipulator claw. Background technique [0002] The manipulator claw is an automatic operation device that can imitate some action functions of human hands to realize grasping, transporting workpieces or operating tools as required, and can replace humans to complete various operations on industrial production lines. Manipulator claws are generally used together with mechanical arms to form an industrial robot system. As the end-executing part of the robot system, the performance of the manipulator claw directly affects or even determines the effect of the robot system in grasping the target and executing the load operation, which is very important for the industrial robot system. [0003] The degree of clamping of the manipulator gripper to the workpiece is very important to its realization function. Obtaining the clamping force of the manipulato...

AI Technical Summary

Problems solved by technology

[0005] (1) Accessories such as guide rods and load cells must be installed on each finger, resulting in complex structure and high quality of the mechanical gripper;

[0006] (2) In order to adapt to the installation of accessories such as guide rods and load cells, the size of the manipulator claws must be large and cannot be miniaturized, and its application is limited;

[0007] (3) In order to detect the clamping force online, the guide rod needs to pass through the guide hole on the manipulator claw to extend out of the end face of the gripper. When it is used for many times or improperly operated, the guide rod is prone to jamming and cannot be pressed back normally, which will affect the gripping of the workpiece. Pick;

[0008] (4) The size of the guide rod is small, when the grasping position deviates, the gripper cannot detect the clamping force

[0009] In summary, the current method of online detection of the clamping force of the manipulator will cause the manipulator to have shortcomings such as large mass, complex structure, and low detection effect. It is an effective solution to use a detection device to detect the clamping force of the manipulator before use. However, there is currently no manipulator clamping force detection device with simple structure, reasonable design, reliable performance, wide application, large transmission force, easy operation, and high detection accuracy.
