Micro clamping device

Abstract

The invention belongs to the technical field of clamping devices, and particularly relates to a micro clamping device which comprises a body and a transmission block. A threaded hole used for connecting a sleeve shell is formed in the body, the body is connected with a worm through the threaded hole, a T-shaped rod used for transmission is arranged at the side end of the sleeve shell, a rectangular groove used for retracting and releasing a handle is formed in the T-shaped rod, a rectangular groove used for sliding of the transmission block is formed in the body, the body is connected with the transmission block through the rectangular groove, the transmission block drives the worm to rotate through transmission of an internal tooth groove due to the arrangement of the sleeve shell, and the worm is connected with the threaded hole in the body through threads of the worm. The body is divided into two parts through the arrangement, the interior of the device is convenient to maintain and replace, meanwhile, the body is detached, clamping cutters are convenient to replace, the same body and the same sleeve shell can be produced, the clamping cutters of different models can be assembled, the production cost is effectively reduced, and the applicability of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of grippers, and in particular relates to a micro gripper. Background technique [0002] The micro-gripper is an important part of the micro-assembly robot system. As the end effector of the micro-assembly robot, its main function is to pick up, transport and release tiny objects (parts), and to complete certain assembly actions. The gripper technology is an important guarantee and key technology for the micro-manipulator to realize the gripping and attitude adjustment of micro-parts; the micro-gripper should have the characteristics of light weight and small size, and it also needs to have a suitable gripping force and gripping range . According to different driving methods, micro-grippers can be divided into vacuum adsorption micro-grippers, electrostatic micro-grippers, piezoelectric micro-grippers, electromagnetic micro-grippers, shape memory alloy micro-grippers, etc. [0003] Due to the different mat...

AI Technical Summary

Problems solved by technology

[0003] Due to the different materials, shapes and geometric dimensions of the operating objects of the original gripper, different types of micro grippers need to be developed to meet the reliable operation of different types of operating objects. In the production process, it is necessary to produce a variety of matching Yes, this also leads to an increase in maintenance and replacement costs during use. During the clamping process, electrical energy is converted into mechanical energy, and the object is clamped by squeezing the two clamping tools. This clamping method is not stable enough, and the clamping The structure of the tool is simple, and the clamping effect is not very good, which leads to the general effect of the work
