刀口式测微计是借助于杠杆传动,使测杆的往复运动变为指针角位移的机械式量仪。常见的刀口式测微计的分度值有0.001毫米、0.002毫米、0.005毫米和0.01毫米四种。这种量仪虽然存在着因杠杆系统易被磨损,而使示值误差增大的缺点,且其中0.001毫米的已被灵敏度高的扭簧比较仪所替代。但刀口式测微计由于结构上比较坚固、简单,并易于修理。因此,目前在机械工业特别是轴承行业中仍然广泛使用。本文介绍它的修理项目、顺序、方法和调整。一、结构与零件的卸装步骤结构见图1。卸装步骤1.拧出表盖上的6个固定螺钉,卸下表
Edge-type micrometer is the use of lever drive, the rod’s reciprocating motion into a pointer angular displacement of the mechanical measuring instrument. Common knife-edge micrometer divider value of 0.001 mm, 0.002 mm, 0.005 mm and 0.01 mm four. Although this gauge has the disadvantage of increasing the indication error due to the easy wearing of the lever system, 0.001 mm of which has been replaced by the high sensitivity torsion spring comparator. However, the knife-edge micrometer due to the structure is relatively solid, simple, and easy to repair. Therefore, it is still widely used in the machinery industry, especially in the bearing industry. This article describes its repair items, procedures, methods, and adjustments. First, the structure and parts of the uninstall steps structure shown in Figure 1. Uninstalling Procedure 1. Unscrew the six captive screws on the cover and remove the watch
