Design and numerical simulation of the new design of the gripper for manipulating of the rotational parts

Abstract

The analysis of the field of application of gripper is carried out. Are allocated perspective areas of development of a robotics. The main difficulties in the application of kinematic schemes for gripping devices with rotary finger movement are described. The prospective application of the kinematic scheme of the gripper with a straight-parallel plane-parallel motion of the fingers is proved when manipulating an object of the "shaft" type. A new scheme of a gripper with a rectilinear plane-parallel finger movement is presented. Its design is simpler and cheaper than known devices of this type. The capability of the gripper design in the engineering analysis environment has been fulfilled. Numerous computer studies of both individual design elements and pairs of objects that are in interaction have confirmed the operability of the developed design. It is established that the frictional force in the mobile components of the gripper design is insignificant, which will not create the prerequisites for a significant increase in size.

Ensuring economic efficiency of flexible fixtures in multiproduct manufacturing

“…The design of flexible fixtures is a complicated and time-consuming process that requires considering many parameters. Kotliar et al (2019b) focused on production conditions; Krol and Sokolov (2018) considered technological capabilities of metal-cutting Engineering Management in Production and Services equipment; Li, Chen and Shi (2016), Kostyuk, Nechyporuk and Kostyk (2019), and Kostyuk (2019) examined parameters of cutting tools; Bakker et al (2013) and Shaik, Rao and Rao (2015) studied design and technological features of parts; Basova et al (2018) and Sokolov, Krol and Baturin (2019) investigated dynamic characteristics; Denysenko et al (2019) and Dynnyk et al (2020) evaluated quality indicators; and Yarovyi and Yarova (2020) appraised energy-efficient criteria. Meanwhile, Qin et al (2010) presented a literature review on existing fixture systems, their functionality, design features, and sufficient use.…”

“…Son and Park (1987) stated that productivity, quality, and flexibility were key indicators of production efficiency integrated into the model for evaluating manufacturing systems used to justify investment in manufacturing systems. Based on Basova et al (2018) and Stepanov et al (2019), the main provisions for calculating the productivity of machining parts intensify cutting modes when choosing the optimal parameters of fixtures.…”

Integrated Approach to Determine Operational Integrity of Crane Metal Structure

“…Further, it is required to build a three-dimensional model of an overhead crane in a computer program (for example, SolidWorks, ANSYS, etc. ), set boundary conditions, apply forces for each stage of STC loading, and carry out modeling by means of the finite element method (FEM) [20][21] and finally, indicate metal structure elements (calculation zones) with an increased stress level and a large stress range ( ) .…”

Parameter Identification of Cutting Forces in Crankshaft Grinding Using Artificial Neural Networks

“…At the same time, it is necessary to note the sharply increased requirements for technical and economic indicators of grinding operations, especially in automated and robotic production. Therefore, under multiproduct manufacturing, it is necessary to consider the criteria of quality [ 3 , 4 ] and energy efficiency [ 5 , 6 ], equipment [ 7 , 8 ] and tooling [ 9 , 10 ] capabilities, processing modes [ 11 , 12 ], the design and technological parameters of the parts [ 13 , 14 , 15 ], the properties of materials and coatings [ 16 , 17 , 18 , 19 , 20 ].…”
