Embodiment approach

[0072] As an implementation manner, the linkage relationship between the elastic element 300 and the moving mechanism 200 includes:

[0073] When the moving mechanism 200 is in the original position, the elastic element 300 is in the original long state;

[0074] When the moving mechanism 200 moves relative to the fixing mechanism 100, the elastic element 300 generates deformation;

[0075] There is a functional relationship between the displacement of the moving mechanism 200 and the deformation of the elastic element 300 .

[0076] In the above implementation process, when the moving mechanism 200 is at the original position and the elastic element 300 is in the original length state, the two have the same reference contrast, which facilitates the establishment of a comparison between the displacement of the moving mechanism 200 and the deformation of the elastic element 300. Concise functional relationships.

[0077] In a possible implementation manner, the functional rel...

Abstract

The invention provides a dustproof constant force device, a mechanical arm, a grinding device and a robot, and relates to the field of intelligent manufacturing. The dustproof constant force device comprises a fixing mechanism, a moving mechanism, an elastic component and a gas input device, wherein the moving mechanism and the fixing mechanism jointly form a sealing cavity with a variable volume;and the sealing cavity is provided with an air inlet. The elastic component is located in the sealing cavity and is configured to have a linkage relationship with the moving mechanism. The gas inputdevice is used for inputting compressed air into the sealing cavity and enabling the internal pressure of the sealing cavity to be always larger than the external pressure. According to the dustproofconstant force device, the mechanical arm, the grinding device and the robot provided by the invention, the moving mechanism and the fixing mechanism jointly form the sealing cavity with the variablevolume, and the internal pressure of the sealing cavity is kept to be larger than the external pressure, so that external powder dust is prevented from entering the sealing cavity. The elastic component and the moving mechanism are linked, and an acting force produced on the moving mechanism through a pressure change value of the sealing cavity is balanced, so that the constant-force input is realized.

Description

technical field [0001] This application relates to the field of intelligent processing, in particular, to a dust-proof constant force device and control method, a mechanical arm, grinding equipment and a robot. Background technique [0002] In automatic grinding processing, objects with irregular surfaces are polished. In order to obtain a smooth surface, it is necessary to maintain a constant force as much as possible. It is easy to generate a lot of dust during the grinding process, and the dust entering the constant force output device will damage the friction surface of the moving parts of the constant force output device. Therefore, in order to prevent dust from entering the constant force output device, a sealing cover or organ is usually used The constant force output device is simply sealed by a structure such as a cover, so that the constant force output device is in a sealed environment. [0003] When the constant force output device is subjected to an external fo...
