1、数控冲床自动送料机机械结构设计摘要本课题对数控冲床自动送料机进行了设计计算。根据物料的运输要求,自动送料装置采用了运输链和槽轮机构运输方式,由此可对送料装置的速度进行调节,以实现速度的可调性。同时,由于链式输送机是常见的连续动作运输设备,其输送能力大、调度组织简单、维护方便、营运费用低,此外它还具有结构简单、运转平稳可靠、运行阻力小、耗电量低、运输距离大,容易实现自动化等特点。而且,由于槽轮机构具有间歇性的运动,因此可达到冲孔自动送料的要求。槽轮机构是一种步进间歇运动机构,由于结构简单、制造容易、工作可靠,能准确地控制转角,机械效率高,所以在自动和半自动生产线中得到广泛的应用;但槽轮在销轴进出
2、槽轮槽口时加速度大,机构产生较大的冲击,而且随着转速的增加和槽轮槽数的减少冲击加剧,因而不适用于高速运转的情况。关键词:送料机,槽轮机构,链传动,数控冲床Design of automatic feeder about CNC punching machinestructureAbstracts:This topic for punching automatic feeding device design calculation, according to the design plan descriptions of transmission system solutions, worked
3、 in a transmission system design. According to the requirement of transportation, punch materials using automatic feeding device transport links and Geneva mechanism, which mode of transportation for feeding device speed adjustment, to realize the continuous bariable speed. At the same time, because
4、 the chain conveyor is common, the continuous action transportation equipment large conveying capacity, simple operation, convenient maintenance, organization, in addition to its low operating cost has simple structure, stable and reliable operation, low power consumption, low resistance and easy tr
5、ansportation distance, automation etc. And, due to the Geneva mechanism with intermittent movement, therefore, can achieve punching automatic feeding requirements.Geneva agencies is stepping intermittent movement,because of Simple structure、manufacturing easy、reliable,Can accurately control angle, H
6、igh mechanical efficiency,Therefore, automatic and semi-automatic production line is widely used; But trough round slot in the round pin and out of the acceleration when Passage,Institutions have a greater impact,moreover, with the speed and the increase in the number of slot groove round of intensi
7、fied to reduce the impact,Thus does not apply to high-speed operation.
