Worm-driven mechanical gripper

Abstract

The invention discloses a worm-driven mechanical gripper. A driving module can drive a worm to rotate, a worm gear can be made to rotate in the worm rotating process, and then the degree of an angle formed by taking a first rotation shaft as a vertex point and taking a second rotation shaft and a fourth rotation shaft as end points is changed; a clamping surface can be displaced in the horizontal direction according to the parallelogram principle, and then clamping is achieved. According to the worm-driven mechanical gripper, driving components adopt simple connecting rod structures, therefore, the reliability is very high, and the life is very long; in addition, transmission of the worm gear and the worm is very precise, and therefore the worm-driven mechanical gripper can achieve precise gripping; meanwhile, transmission of the worm gear and the worm can achieve the effects of reducing the speed and increasing the torque and the clamping force. Therefore, the problem that the size and the mass are large due to the fact that a speed reducing mechanism needs to be additionally arranged on a mechanical gripper in the prior art is avoided. The worm-driven mechanical gripper is applied to the field of mechanical grippers.

Description

technical field [0001] The invention relates to a worm driven mechanical claw. Background technique [0002] The manipulator is the earliest industrial robot and the earliest modern robot. It can replace the heavy labor of people to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety. An important part of modern robots is the manipulator grasping, but the existing manipulator structure design is unreasonable, the grasping force is small, and the control is not precise. It often requires a lot of debugging before use, which is time-consuming and labor-intensive. [0003] Furthermore, when the current robot is grabbing products of different sizes, its fingers can only grab products of a certain size in parallel, but cannot grab other products in parallel, which leads to unstable gripping The common technical means of those skilled in the art is to set up soft materials such as cushions to achieve grasping,...

An important part of modern robots is the manipulator grasping, but the existing manipulator structure design is unreasonable, the grasping force is small, and the control is not precise. It often requires a lot of debugging before use, which is time-consuming and labor-intensive.

[0003]Furthermore, when the current robot grabs products of different sizes, its fingers can only grab products of a certain size in parallel, while other However, the product cannot be grasped in parallel, which leads to the occurrence of unstable grasping. The usual technical means of those skilled in the art is to set soft materials such as cushions to achieve grasping, but such cushions are prone to partial transition, wear and tear. It also makes the product stress uneven
