Model of large-scale vehicle matching the main body panel to adjust the design of analog blocks of the problem

2) The adjustment of the same effect; (3) different adjustment mechanism. Figure 6 Conventional fender master model 2 different regions although the structure of the above can be achieved as the final testing and adjustments, but two kinds of structural adjustment period for the measurement and processing costs have had a significant difference, following this analysis. 3.1 The main model system in the conventional manufacturing costs and the adjustment mechanism of the first measurement period, outside the main model used to understand the Figure 7 shows that, adjusting the body is adjusting plate from the non-standard size and composition of the various cast bracket. Figure 7 used to indicate the adjustment of body (front fender area) (1) from measurements of the angle adjustment mechanism to adjust and the adjustment cycle, such as measuring the reasonableness of the workpiece to be adjusted to the displacement vector Z, then, a large area of adjustment of the grinding plate For the amount of wheel wear and tear is not the economy, and adjust the cycle length. (2) from the perspective of manufacturing costs and processing cycle adjustment mechanism reasonableness standard and non-standard thickness of the cast support brackets respectively the thickness of billet casting processing, milling benchmarks, margin and CNC machining to install the larvae L-bit,mulberry helsinki, etc. work. The difference between the two is obvious. 3.2 The main model in the adjustment of the body both inside and outside the manufacturing costs and the measurement cycle analysis Secondly, the main model to understand the adjustment of internal and external agencies (see Figure Cool

. Figure 8 shows that the adjustment of the body is all steel mounting bracket and the standard size of the adjustment sheet. (1) from measurements of the angle adjustment mechanism to adjust and the adjustment cycle, such as measuring the reasonableness of the workpiece to be adjusted to the vector z, just adjust the grinding plate can be adjusted height Z to the other, both inside and outside the main model for a plate by its smaller size, so the adjustment period, the processing area is decreased to significantly reduce the amount of grinding, grinding time decreased, the detection efficiency will be increased. 4DieandMouldTechnologyNo. 62009 points shown in Table 1. Application of its characteristics, high hardness, polishing better, wear better, higher tensile strength and compressive strength. For high and high degree of polishing required modules, suitable for PA, P () M, PS, PE, PP, ABS. Table 1718H Chemical Composition% Figure 8, after optimization of advanced adjustment mechanism to indicate {front fender area) 4 Conclusion (2) from the perspective of manufacturing costs and processing cycle to adjust institutions within and outside the main model of the rationality of the steel material used on the installation bracket are the same thickness, from the machining process, because the thickness of the same parts, so only the thickness of the unified control of stock,ed hardy mexico, part shape can be cut through the line in a working position within the processing end, helps to reduce the process, but also for processing. From the processing cycle, the ability to achieve mass production, processing cycle can be shortened. Finally, it is worth mentioning that, inside and outside the main model used in the adjustment of the adjustment plate is X, y to the two vector displacement, z the vector is a thin plate to be adjusted. Plate designed to adjust the size,mulberry københavn, shape, holes are the same standard parts. 3.3 The main model for the steel material inside and outside the mounting bracket materials Selection of materials will affect the internal stress to the blank, the deformation coefficient and the hardness of the material itself,mulberry sverige, so replacing the inside and outside the main model to be demolished under the control mounting bracket part material hardness. At present the main model to replace the original steel inside and outside the mounting bracket of the material is usually material selection 718H. 718H for the Pre-hardened plastic mold steel quality, the hardening and tempering to 330 ~ 370HB,ed hardy shop, described several chemical costs to adjust their thinking and adjust the body, applicable to almost all types of master model simulation of block structure panel design. Rational use of these methods not only make the adjustment mechanism designed to achieve simple, convenient, practical, standardization and cost control requirements, and shorten the manufacturing cycle of the main model, assembly cycle and measurement cycle, improve work efficiency.
