Accuracy of assembly process of air-heated automobile heater
The assembly accuracy of the air car heater often determines the quality of the heater. Let's talk about the process of assembling car heaters.
Ensure the assembly accuracy of the air-heated car heater, so that the machine can have normal working performance. The accuracy of assembly mainly includes the accuracy of mutual cooperation, relative motion accuracy, and mutual position accuracy between parts.
(1) Fitting accuracy
Refers to the mating quality and contact accuracy between mating surfaces, such as whether the mating method is clearance or interference, contact surface form and so on.
(2) Motion accuracy
Refers to the accuracy of the movement direction and relative movement speed between the relative moving parts in the air heating heater, such as transmission accuracy and rotation accuracy.
(3) Position accuracy
Refers to the distance accuracy and mutual position accuracy between related parts in the air heater, such as distance size and accuracy requirements between parts, parallelism, various runout degrees, perpendicularity and coaxiality, etc.
In general, the assembly accuracy of the air heater is guaranteed by the plus T accuracy of the relevant component parts. The machining accuracy of the parts is the basis for ensuring the assembly accuracy, and the assembly process is the method and means to ensure the assembly accuracy.
Nanfeng auto heater has a professional car heater production line, and the precision control of the assembly process is strict. Strict quality control, to ensure that you can rest assured.
