The traditional metal plate bending process is difficult to meet the requirements of modern shipbuilding industry, and this paper adopts a new incremental bending process for manufacturing metal plate based on minimum energy principle and dieless forming. This process uses a set of punches and a series of highly adjustable and head rotatable supports to complete the punching process by changing the...
Surface polishing is a crucial final process of many manufactured parts. Presently, the process is heavily dependent on the skill of the trained workers and hence, is time consuming, expensive, error-prone and environmentally unfriendly. This paper presents a force controlled flexible robot polishing system utilizing a specially designed active end effector with a multi-step path planning. The main...
The cycloid drive usually has a cycloidal wheel meshing with pins to achieve transmission. The profile of the cycloidal wheel is generally a curve derived from an epitrochoid. This paper presents two design types of cycloid drive, the cycloidal wheel profile of one is internal offset of epicycloid and the other is external offset of hypocycloid. Parametric 3-D models of the two design types are constructed...
In this paper, a new type of magnetic wheeled wall-climbing robot is proposed in order to overcome the shortcomings of existing climbing robots. It takes advantage of SOLIDWORKS to establish a three-dimensional model. Also, the paper introduces the design idea of wall-climbing robot, uses MATLAB to do the numerical analysis and make magnetic simulation through ANSOFT MAXWELL.
Precision reducer is one of the key parts of an industrial robot, which generally incorporates two-stage cycloidal planetary drive. The theoretical engagement of cycloidal wheel and pin is a gapless engagement, but in practice, there is a gap between the cycloidal wheel and the pins due to manufacturing errors. Most of the previous research on the gap only involves the impact on the transmission accuracy,...
Cavitation nozzle is the core component of cavitation generator. It promotes cavitation by its internal special structure, producing bubble and improving the impact force of jet. The structural characteristics directly affect the quality of the cavitation jet. Therefore, the study of internal structure of nozzle is helpful to improve the performance of nozzle. Based on CFD software, taking the Helmholtz...
A new type of crawler-type magnetic adsorption wall-climbing robot for derusting of ships was designed. The three-dimensional model of the robot, the adsorption device and the cleaning device, were established by SOLIDWORKS, and the static force model was established according to the actual working condition. Then, two kinds of common overturning risks of the wall-climbing robot were analyzed and...
As an ideal candidate for biology information detection, flexible resistance-array-type sensors have attracted extensive attention. But owing to the Neighbor Disturbance in resistance array, the accuracy of the sensors has been limited greatly. In the presented work, a novel resistance measuring circuit has been developed with equipotential shielding method, which shows a better accuracy in detecting...
This paper has designed a gold press polishing control system based on FPGA and feedback technology. This paper uses SOPC and NIOS soft core as the core of control system. At the same time, three level PID control scheme is used. The force feedback control is the main one, the, position and current feedback are au Also the paper designed the debugging software based on MFC for condition monitoring...
