The Design And Model Analysis Of Key Structures Of The Three-dimensional And Profiling Edging Machine For Rearview Mirror

Glass edging machine is a kind of glass deep processing equipment. Since the1990s,it went through the manual edging machine to the profiling edging machine to CNCgrinding machine. The technology and the machining accuracy are constantly improving.According to the classification of the shape of edging, it mainly includes straight-lineedging machine, bevel edging machine and irregular edging machine. This article mainlyresearch on edging and chamfering machine for rearview mirror. It is a kind of irregularglass edging machine belong to Special-purpose glass edging machine.Most of rearview mirrors are big curvature spherical mirrors. Its edging andchamfering are indispensable procedures. The edging methods are the manual grindingand the edge grinding with bevel grinding. The first method is labor-intensive and lowpass of product quality. The second method is a complex and inefficient process and highequipment cost. There are no relevant standards and regulations about edging andchamfering of rearview mirror. Small and medium-sized enterprises tend to adopt manualgrinding. But, with the rapid development of automobile industry, people are eager to havea stable quality, convenient operation, low cost of equipment manufacture of edging andchamfering equipment. So a three-dimensional and profiling edging machine for rearviewmirror was developed with an enterprise.Starting from the structure and shape features of rearview mirror, based on thegrinding and chamfering technology, considering the difficult degree of processing andequipment cost, according to the principle of profile modeling technology, athree-dimensional grinding principle is found out. Design out key components of machine–fixture, Anti-crash device and similar cam. Select the type of clamping cylinder andelastic cylinder. Set up the UG model of machine. Complete model analysis of swing armand grinder bed and the design of PLC. The prototype of N109WH was retrial-produced.Product analysis results meet customer requirements. It has brought goodsocial and economic benefits to the enterprise.
