Q:In the mechanical design process, those areas should be designed to fillet. When will it be designed to chamfer? 10
Chamfering and roundingIn order to facilitate assembly and operation safety, the shaft ends and holes are usually made into a small cone to remove sharp edges and burrs. This cone is called chamfer.The size of the chamfer can be checked by the standard GB6403.4-86. Generally, the larger the axle diameter and the aperture, the greater the axial size of the chamfer.For the shafts and holes of the ladder, in order to avoid cracks due to stress concentration, the larger parts of the force are often transferred at the shoulder of the shaft and the fillet of Kong Jian, which is called the reverse circle.See: "mechanical design manual" (Third Edition), the first volume, the fifth chapter, parts cold processing, design, process and structural factors
Q:Mechanical design, how to understand the parts processing technology,
1. design is a process of planning, planning, and imagining communicating through visual form.2., human beings transform the world through labor, create civilization, create material wealth and spiritual wealth, and the most basic and important creative activity is creation. Design is the creation of activities that are planned in advance and can be understood as the design, technology, and planning process of any creation.3., first of all, understand the user's expectations, needs, motivations, and understand the needs and limitations of the business, technology, and industry.
Q:I am engaged in the mechanical design work, asks the three-dimensional mechanical component model to download the website.
To Cadenas partcommunity download, under their own Baidu search, there are hundreds of manufacturers above the product model, the standard parts of all countries, free of charge, just register. Choose the format you want. The format is common.
Q:How to design the power assisted robot, mechanical structure and pneumatic part, please point out, thank you!
1. pneumatic manipulator mechanical structure can complete the upper, lower, left, right two directions of movement and clamping, pass, to the sub bar, FA pass, looking for Witkey is too simple
Q:Can the bearings used in the design of mechanical equipment be used as part drawings?
(2) general drawing in section view, when there is no need to exactly express the contour of rolling bearing, load characteristics, structure characteristics, can be rectangular wire frame and cross shaped sign is located in the central line frame upright said cross symbol should not contact with the rectangular frame line, as shown in figure a. The general drawing is drawn in the same way on both sides of the shaft, as shown in Figure B. (3) characteristic drawing and prescribed drawing. The characteristic drawings and rules for rolling bearings are listed.
Q:What is the principle of selecting materials for machine parts in mechanical design?
Cost considerations should be taken into account in mechanical design. If the material used in the design is too good, resulting in the overall cost is too high, it will make the loss of enterprises. The 45 steel is a slightly higher quality carbon structural steel, only in some major components or shaft parts only use 45 steel, and more use of lower strength Q235 and other carbon structural steel.
Q:Does the SolidWorks mechanical design engineer paint parts individually or draw parts in an assembly?
Either way, in actual work, the two approaches may alternate.If you do is mechanism design, may be other assembly references, can consider each part separately draw, so in the future by other assembly references when good maintenance, no loss of reference.If you do need to consider other parts of the related parts, such as the appearance of the skin, a variety of sports organizations, etc., can be considered to create parts in the assembly, can avoid some mistakes when combined with other parts. However, it is still recommended that you minimize the external reference in the assembly and make the key features that require external reference, and that the rest of the features are still done in an independent part manner.
Q:What exactly is mechanical design?
Mechanical design (machine, design),According to the requirement of the mechanical structure, working principle, motion, force and energy transfer, the various parts of the material and shape size and lubrication methods for design, analysis and calculation and put it into specific description as a basis for the manufacturing process.
Q:The strength criterion of mechanical parts design is briefly introduced
1, the strength criterion requires that the working stress of the mechanical parts should not exceed allowable stress [Sigma]. The formula is typical: (3-16) lim - ultimate stress of brittle materials by static stress on the ultimate strength, the static stress of plastic materials, the yield limit of zero stress the fatigue limit. S - Safety factor. 2. stiffness criteria mechanical components are subject to elastic deformation when subjected to load. Stiffness is the ability to resist deformation of materials, mechanical parts, or structures subjected to external forces. The stiffness of the material is measured by the external force required to produce the unit deformation. The stiffness of a mechanical part depends on its modulus of elasticity, E or shear modulus, G, geometry and size, and the form of external forces. It is an important work in mechanical design to analyze the rigidity of mechanical parts. For some parts that need to be strictly deformed (such as wings, machine tools, spindles, etc.), stiffness analysis is necessary to control the deformation. We also need to control the stiffness of the parts to prevent vibration or instability. In addition, a spring, such as a spring, must be used to control its stiffness to a reasonable value to ensure its specific function. The stiffness criterion is that the elastic deformation of a component subjected to load is not greater than the allowable elastic deformation. The expression of the stiffness criterion is (3 - 17) y is an elastic deformation quantity, such as deflection, longitudinal elongation (shortening): [y] is the corresponding allowable elastic deformation. The elastic deformation of a part can be obtained by theoretical calculation or by experiment. The allowable deformation depends on the use of the part, and is determined by theoretical analysis or experience.
Q:What is standardization, serialization, and generalization?
Serialization refers to the same product, under the same basic structure or basic conditions, set out a number of different size seriesGeneralization refers to the parts and components of the same structure and size, which are used in different kinds of products or different specifications of similar products"Article three" the main benefits are: to reduce the design workload, improve design quality and shorten the production cycle; reducing tool and gauge specifications, easy to design and manufacture, thereby reducing the cost; for the organization of standard parts of the scale, specialization, to ensure product quality, material saving, cost reduction; improve interchangeability, easy maintenance; macro management and regulation for the country and in foreign trade; to facilitate evaluation of the quality of products, to solve the economic disputes.
