Assembly after the first assembly or overhaul has great influence on the performance of the equipment.

The sewing machine with poor assembly quality has low precision, poor performance, loud noise, heavy torque and short life. On the contrary, some parts with very low precision can be assembled with better performance by careful assembly and precise adjustment.

In the assembly process, some links are easy to be ignored, which often causes obvious influence on the assembly quality and needs attention.

First, ensure the cleanliness of parts and components.

By carefully cleaning and cleaning, ensuring the cleanliness of sewing machine parts is the basis for ensuring assembly quality and prolonging the service life of sewing machines.

In particular, the shaft sleeve, bearings, oil pumps, and parts with rotating and swinging parts should be carefully cleaned.

If the shaft assembly is not clean, the axle sleeve will be overheated and the pmission torque will be too heavy. If it is serious, it will accelerate wear due to debris, and there will be serious failures such as "occlusion".

Two. According to program operation

All parts of the sewing machine, including surface baking, electroplating and other surface treatment, have adhesive layers on the assembly joint surface (including holes, grooves, planes and holes). Therefore, before assembly, the parts must be processed according to the technological requirements, and then they can be put into assembly.

State.

If the assembly fails to meet the requirements

Sewing machines are not working properly.

The incorrect position between parts and mechanisms also affects the performance of sewing machines.
