一、夹具设计的要求1.以轴承盖模锻毛坯定位,余量每边厚度为3～4毫米;2.因流水线上用,故输入一个信号或用手动开关即可自动定位、夹紧;3.工件加工厚度为96毫米,所以,夹具厚度必须小于96毫米,以便铣刀能顺利通过;4.该夹具要有足够的刚性与夹紧力;5.夹具要便于机械手上下料;6.夹具要求定位、夹紧先后顺序动作。按上述要求设计夹具中曾考虑过多种方案,都难以实现自动控制的目的。
First, the fixture design requirements 1. Bearing cover forging blank positioning, the margin of each side thickness of 3 to 4 mm; 2. Because the pipeline used, so enter a signal or manually switch can be automatically positioned, clamping; 3. Workpiece processing thickness of 96 mm, so the thickness of the fixture must be less than 96 mm, so that the cutter can pass smoothly; 4. The fixture must have sufficient rigidity and clamping force; 5. Fixture to facilitate loading and unloading manipulator; Fixture requires positioning, clamping sequence of actions. According to the above requirements have been considered in the design fixture a variety of programs are difficult to achieve the purpose of automatic control.
