Allowance treatment static designed couple and repeatable precision in assembly

Abstract

Abstract. In practice, we deal with static designed couples frequently. Construction engineers use them so they can upscale rigidity of product. In paper are described principles how to change after effects of problematic assembly in often used feed couples which use to be statically designed. Important problem in assembly is repeatable precision, mainly in construction of assembly lines. By imprecision of robot which inserting shank into the hole and by imprecision of position of hole in carrier shank won't be successfully inserted. In article are shown reasons and security approach of repeatable precision in assembly operations executing.

The mould for production of plastic spout cap with internal thread by injection moulding

“…Nowadays, the simulation play very important role in pre-production phase and can have massive influence on the final costs and efficiency of processes [17][18][19][20]. SolidWorks Plastics provides an effective injection moulding simulation tools which can help to identify production limits and predict potential failures and consequently eliminate them even in the early stages of product development [15,21].…”

The Method of High Accuracy Calculation of Robot Trajectory for the Complex Curves

“…Authors [8] solve the Apostol-Euler-Dunkl polynomials with applications to series involving zeros of Bessel functions, and author in [9] describe the growth of polynomials outside of a compact set-The Bernstein-Walsh inequality revisited, and further, the authors [10] deal with the approximation and Entropy Numbers of Embeddings Between Approximation Spaces. Many outputs of approximation techniques are widely used in mechanics, economics, mechatronics, robotics [11,12], instrumentation, technology [13,14,15], assembly [16,17], informatics [18,19] etc. The general disadvantage of all methods is that they have miscalculations.…”

The future of industry with collaborative robots

“…Innovations of robotic assembly or production in current are taking place through the introduction of a collaborative robot into the process in collaboration with humans [8]. Compared to industrial and collaborative robots, a comparison of their benefits for practical use is made.…”
