卡扣在设计时需要注意以下几点
1)、选择合适的变形量。卡扣通过紧固件的变形和反弹来实现安装。而太小的变形量容易造成安装不牢固;太大的变形量又容易导致安装困难甚至无法安装,破坏卡扣。
1) Choose the appropriate deformation. The clamp is installed by deforming and rebounding the fastener. However, too small deformation can easily lead to unstable installation; too large deformation can easily lead to installation difficulties or even unable to install, destroying the buckle.
2)、设计时,注意要使卡扣在安装靠位时出现一些比较明显的现象,如声音以及手感上的变化。
2) When designing, attention should be paid to some obvious phenomena, such as changes in sound and feel, when the clamp is installed in the berth.
3)、设计时,注意卡扣的约束数量,不能出现过约束的情况。约束过多,对零件的加工精度要求较高。在实际装配过程,容易导致安装不到位或不能安装。
3) When designing, we should pay attention to the number of constraints of the clip, so that no fuzhou.89ix.comhaikou.89ix.com shanghai.89ix.comtianjin.89ix.comchongqing.89ix.comxin.75ix.comconstraints can occur. Too many constraints require high processing accuracy of parts. In the actual assembly process, it is easy to cause the installation is not in place or can not be installed.
