.配合精度
Fit precision
在弹簧机装配过程中大部分工作是保证零部件之间的正常配合。为了保证配合精度,装配时要严格按公差要求。目前常采用的保证配合精度的装配方法有以下几种。
Most of the work in the spring assembly process is to ensure the normal coordination between parts. In order to ensure the accuracy of assembly, assembly must be strictly in accordance with the requirements of tolerance. Currently used to ensure the accuracy of assembly methods are the following.
(1)完全互换法
(1) complete exchange method
相互配合零件公差之和小于或等于装配允许偏差,零件完全互换。对零件不需挑选、调整或修配就能达到装配精度要求。该方法操作方便,易于掌握,生产效率高,便于组织流水作业,但对零件的加工精度要求较高。适用于配合零件数较少、批量较大的场合。
弹簧机
The sum of the parts of the mating parts is less than or equal to the allowable deviation of the assembly. The assembly accuracy can be achieved without the need of selection, adjustment or repair. This method is easy to operate, easy to master, high production efficiency, easy to organize the assembly line, but the processing precision of parts is higher. It is suitable for occasions with small number of parts and large batch.
(2)分组选配法
(2) group selection method
这种方法零件的加工公差按装配精度要求的允许偏差放大若干倍,对加工后的零件测量分组,对应的组进行装配,同组可以互换。零件能按经济加工精度制造,配合精度高,但增加了测量分组工作。适用于成批或大量生产,配合零件数少,装配精度较高的场合。
In this method, the machining tolerance of parts can be enlarged several times according to the allowable deviation of assembly precision requirement. Parts can be manufactured according to the accuracy of economic processing, with high precision, but increased the measurement of grouping. Suitable for batch or mass production, with fewer parts and high assembly accuracy.
(3)调整法
(3) adjustment method
选定配合副中一个零件制造成多种尺寸作为调整件,装配时利用它来调整到装配允许的偏差;或采用可调装置如斜面、螺纹等改变有关零件的相互位置来达到装配允许偏差。零件可按经济加工精度制造,能获得较高的装配精度。但装配质量在一定程度上依赖操作者的技术水平。调整法可用于多种装配场合。
With a pair of selected parts to various sizes as the adjusting piece, use it to adjust the assembly deviation to permit assembly; or use of adjustable device such as slope, the change of the relevant parts of the thread to achieve the mutual position deviation assembly. Parts can be manufactured according to the economic processing precision, can obtain high assembly accuracy. But the assembly quality depends on the technical level of the operator to a certain extent. Adjustment method can be used for a variety of assembly occasions.
