断桥铝双头切割锯零件误差造成哪些影响？

断桥铝双头切割锯行为误差对机械产品的工作精度、链接强度、运动平稳性、密封性、耐磨性、配合性质以及可装配性都会产生影响，引起噪声，缩短双头切割锯的使用寿命，一般来说，可归纳为以下三个方面：
The behavior error of the broken bridge aluminum double head cutting saw will affect the working accuracy, link strength, motion smoothness, sealing, wear resistance, matching property and assemblability of mechanical products, causing noise and shortening the service life of the double head cutting saw, generally speaking, it can be summed up in the following three aspects:
1. 影响断桥铝双头切割锯零件的功能要求，例如双头锯导轨表面的直线度、平面度不好，将影响双头锯切割锯片的运动精度，齿轮箱上个轴承孔的位置误差，将影响齿轮传动的齿面接触精度和齿侧间隙，钻膜、冲模、锻模等工作表面，其性质误差则会直接影响其工作精度或被切割型材的几何精度。
1. the functional requirements of the double head cutting saw parts of the broken bridge, such as the straightness and flatness of the surface of the double head saw, will affect the motion accuracy of the saw blade of the double head saw and the position error of the bearing hole on the gear box, which will affect the contact precision of the tooth surface and the clearance of the tooth side, and the work of the drill film, die, forging die and so on. As for the surface, the quality error will directly affect its working accuracy or the geometric accuracy of the cut profile.

2. 影响断桥铝双头切割锯零件的配合性质，形状误差会影响零件表面间的配合性质，造成间隙或郭颖不一致。对于间隙配合，局部磨损加快，降低零件的运动精度，缩短零件的工作寿命。对于郭颖配合，影响连接强度。

2. influence the matching properties of the parts of the broken bridge aluminum double head saw, the shape error will affect the matching nature of the parts surface, resulting in gap or Guo Ying disagreement. For clearance fit, local wear is accelerated, the motion accuracy of parts is reduced, and the working life of parts is shortened. For Guo Ying coordination, it affects the strength of the connection.
3. 影响零件的自由装配性。位置误差不仅会影响双头切割锯零件表面的配合性质，还会直接影响零、部件的可装配行。例如，若法兰端面上空的位置有误差，就会影响零件的自由装配性，电子产品中，电路板、芯片的插角位置误差会影响这些器件在整机上的正确安装。
3. influence the free assembly of the parts. Position error will not only affect the matching properties of the surface of double headed saw, but also directly affect the assembly line of parts and parts. For example, if the position of the flange face is error, it will affect the free assembly of the parts. In electronic products, the position error of the plug angle of the circuit board and chip will affect the correct installation of these devices on the whole machine.
总之，断桥铝双头切割锯零件的形状和位置误差对其使用性能的影响不容忽视，为保证产品的质量和零件的互换性，应规定形状和位置公差，以限制其误差。
In a word, the influence of the shape and position error of the broken bridge aluminum double head cutting saw can not be ignored. In order to ensure the quality of the product and the interchangeability of the parts, the tolerance of shape and position should be stipulated to limit its error.
