2.定位用胎夹具图28示出确定构件相互位置的三种方法。其中a)为将构件与定位板贴合的定位方法。采用该法时,操作者可不必担心装配尺寸方面的问题,因而该法简便。然而,如当定位板的装配有偏差时,与之贴合的构件也相应地产生同类偏差。b)为小批量生产时通常采用的一种定位方法。其定位是按装配线进行的。采用此方法时,必须严格按装配线定位;其优点在于:仅用简易夹具就可解决定位问题。c)为依靠构件与胎具基准面的贴合进行定位的方法。采用该法定位,需付出高于简易胎夹具的成本。
2. Timing Fixture FIG. 28 shows three methods for determining the mutual position of members. Wherein a) for the positioning member affixed with the positioning plate. With this method, the operator does not need to worry about the size of the assembly problem, so the method is simple and convenient. However, as in the case of deviations in the mounting of the locating plate, the components to which they are attached also have similar deviations. b) One of the commonly used positioning methods for small batch production. Its positioning is done by assembly line. When using this method, it must be rigorously positioned by the assembly line; its advantage is that positioning problems can be solved with simple fixtures. c) To rely on the component and the tire reference surface positioning method. The use of the law positioning, need to pay higher than the cost of simple tire fixture.
