长齿条的精加工,一般是在万能铣床上通过分度蜗杆,蜗轮减速搭配挂轮带动纵向丝杆,来控制工作台的位移尺寸。由于其传动误差较大,定位精度不高,易产生废品,进一步提高加工精度受到限制。为此应用数显装置对捷克制造的卧铣进行了精化改造,有效地补偿了上述误差,减轻了劳动强度,能方便的铣削各种模数或径节制齿条,提高了产品质量。改造要点 1.选型时应根据设备状况,工艺要求,加工环境,安装空间以及维修条件等综合考虑。对旧机床的改造,选用普通型的多,与其相配的传感器精度要求相适应,一般分辨率与精度的配合关系保持在1/3～1/5为宜。 2.为了保证测量精度,安装时必须按照使用说明书上的技术要求进行。数显表架一般为附装式的活动支架,由回转、锁紧等简单机械结构组成。定尺装在
Long racks of finishing, the general is universal milling machine through the indexing worm, worm gear with hanging gear driven longitudinal screw to control the displacement of the table size. Due to its large transmission error, positioning accuracy is not high, easy to produce waste, to further improve the processing accuracy is limited. For this reason, the digital display device has been used to refine the horizontal milling made in Czech Republic, effectively compensating the above errors, reducing the labor intensity, conveniently milling various modulus or diameter control racks, and improving the product quality. Transformation points 1. Selection should be based on equipment status, process requirements, processing environment, installation space and maintenance conditions and other comprehensive consideration. The transformation of the old machine, use more common type, and its matching sensor to meet the accuracy requirements, the general resolution and accuracy of the relationship maintained at 1/3 to 1/5 is appropriate. 2. In order to ensure the measurement accuracy, the installation must be carried out in accordance with the technical requirements of the instruction manual. Digital display stand is generally attached to the activities of the stent, the rotary, locking and other simple mechanical composition. Installed on a fixed length
