Entering the front line of machining production (1)
The Hengli motor machining workshop is mainly responsible for metal cutting, which is the process of cutting off excess parts from the blank using a lathe to obtain the required geometric shape, size, and surface roughness of the parts or semi-finished products. The commonly used mechanical processing methods include turning, milling, planing, grinding, and drilling.
Overview of Machining Process for Motor Products
Mechanical processing is an important component of the manufacturing process for Hengli motors. The precision, dimensional accuracy, and roughness of motor components are mainly achieved through mechanical processing methods. The quality level of mechanical processing directly affects the overall quality grade and compliance with design goals of the motor, greatly affecting its performance and lifespan. Mechanical processing accounts for about 25-30% of the total labor required for manufacturing motors at Hengli Electric, and the number of people in the machining workshop is about 30%
At present, the percentage of mechanical processing labor in the motor manufacturing industry is gradually decreasing. This is due to the continuous improvement of the structural processability of components and the increasing accuracy of blank manufacturing, which reduces the workload of mechanical processing. With the continuous improvement of the performance of metal cutting machine tools and cutting tools, as well as the adoption of combination machine tools, assembly lines or automatic production lines, the productivity of mechanical processing has been significantly improved. However, this does not mean that the role of mechanical processing technology research in motor manufacturing tends to be marginalized, and the importance of process schemes and routes is more prominent.
The components that require mechanical processing in motors include the seat, end cover, shaft, rotor bracket, rotor, bearing cover, commutator, slip ring, as well as the base plate, bearing seat, and bearing shell of large motors. In order to save costs, Hengli Motors outsources many components and selects suppliers who are at the middle to high level in the motor industry.
Interchangeability of motor components
In batch production and mass production of components, without selection and repair, any part or component of the same specification can be easily assembled onto the product and the quality of the product can be guaranteed. The property that parts or components of the same specifications can be interchanged and used is called interchangeability of parts or components.
With interchangeability of components, they can be professionally produced by Hengli Electric's specialized workshops or factories using advanced manufacturing methods, greatly improving labor productivity and reducing product costs. At the same time, it can shorten assembly time and improve assembly quality in terms of assembly. In terms of repair, when a part or component is damaged, it can be quickly replaced with a new part or component. The larger the production scale, the more important the interchangeability of components becomes.
In terms of usage units, the motor itself is often used as a component or part. Firstly, it is required that motors of the same specifications can be installed interchangeably, and secondly, detachable components can be used interchangeably.
