Abstract
This article is aimed at the engineering design of a manipulator, which is pneumatically controlled. It will serve for mounting the compressor of an air suspension system to the chassis of a sport utility vehicle (SUV) produced in the Slovak Republic. The manipulator will be used on an assembly line, on which SUVs are assembled. The designed device belongs to a group of dedicated devices, which are not produced within a serial production, however, it is the only functional prototype. Together with the manipulator structure, a pneumatic part of the assembly line including individual components, schemes and the pneumatic system will be proposed. Within the project process, all necessary customer demands, technical and safety standards have to be met. Moreover, ergonomic requirements for handling the device and other acts on the workplace have to be considered.
Highlights
Controlled mechanisms are mechanisms that use the pressure force change for the incurrence of a rectilinear or rotational movement
High speeds, automatisation possibilities as well as fire safety, pneumatic systems are used in food processing, optics, production lines, building industry and in the automotive industry
If the compressor is in the proper position, the control panel shows by means of the green pneumatic pilot light Festo OH-22-BL, the correctness of placing
Summary
Controlled mechanisms are mechanisms that use the pressure force change for the incurrence of a rectilinear or rotational movement. High speeds, automatisation possibilities as well as fire safety, pneumatic systems are used in food processing, optics, production lines, building industry and in the automotive industry. For other requirements to be considered, we include [2, 3]: - the manipulator structure has to respect the mechanical actuation of the device and the weight of the mounted component, - the manipulator structure, type and location of control elements have to be chosen with respect to the device operating staff, that is, the device has to be controlled by just one operator, - compactness, stiffness and the minimal weight of the manipulator, - the air compressor has to be attached on the manipulator arm without clamps, - guaranteed the possibility of the subassembly of the compressor on the manipulator arm, - reliable fixation of the manipulator to the chassis without damage, - a longitudinal rail system equipped with three sensors (optical, acoustic and shut), - the manipulator has to be equipped with sensors of medium consumption (compressed air and electric energy), - reliable mounting of the compressor to the chassis, that is, the guidance of the mounted component by the manipulator towards the chassis, - guaranteed access to screw connections during the process of assembling, - an adjustable frame of a compressor on the manipulator arm, - the fastened arm of the manipulator, that is, braked in extreme positions, - simple maintenance, - any metal component of a compressor support must not be in a contact with a mounted component or the car
