Description

Technical Field

[0001] The utility model relates to the technical field of motor detection, in particular to a clamping device for detecting a micro special motor. Background Art

[0002] A gripper is a device that holds an object and manipulates it. It is able to clamp and release an object while performing certain actions. Motion devices often imitate the movement of the human body, and in the case of grippers, it is the movement of fingers that is imitated. The "fingers" themselves are not part of the gripper, they are just special custom tools used to clamp objects, called "jaws", and the most widely used gripper is the pneumatic gripper; it is essentially a cylinder powered by compressed air. When air is supplied, the gripper jaws will approach the object and firmly grasp the object to perform other operations, and when the air direction changes, the gripper will release the object. Typical applications are changing the direction of an object or moving an object in a pick and place operation. When the gripper clamps the workpiece, there should be certain force constraints and shape constraints to ensure that the clamped workpiece should be completely released during the movement, stop and loading process. In addition, it should also ensure that the workpiece clamping posture reproduces the geometric deviation within a given tolerance band, external clamping and internal clamping.

[0003] After searching, the Chinese patent publication number CN212007286U discloses a clamping device for detecting micro special motors, including a clamping device base plate, the upper end surface of the clamping device base plate is provided with a metal mounting block, both sides of the metal mounting block are provided with a first connecting block, and there are four first connecting blocks, the four first connecting blocks are welded to the two sides of the metal mounting block, and the four first connecting blocks are threadedly connected to the clamping device base plate through a first bolt mechanism, and there are four first bolt mechanisms. The above patent has the following shortcomings: although the patent can clamp and fix the motor to be detected, it can only fix a single motor at a time, which reduces the detection efficiency of the detector. In view of this, we propose a clamping device for detecting micro special motors. Utility Model Content
