The frame is a very critical part of the motor. Compared with parts such as end covers, since the iron core is pressed into the frame, it will become a component that is not easy to disassemble. Therefore, people should pay more attention to the quality compliance of the frame. Some.
The diameter and coaxiality of the notch of the machine base and the iron core are a very critical element and a necessary condition to ensure the normal operation of the motor. To ensure the coaxiality of each other, there must be reliable technology and equipment to support. In the traditional process, one end of the spigot is processed in place as a reference, and then the iron core and the diameter of the other end of the spigot are processed. This process requires the diameter and height of the positioning tire processed by the machine base to meet the requirements. Otherwise, it is difficult to ensure mutual compatibility. Concentricity requirements.
If the diameter of the three processed parts is processed on the same basis, the problem of coaxiality can be easily solved, and the single-head boring machine is a very suitable equipment.
From the quality control of machine base processing itself, to solve the problem of coaxiality, it is necessary to comprehensively consider the installation and clamping of the processing process, and achieve the final conforming effect through detailed and effective process detail control.
Boring machine classification and application characteristics
The boring machine is divided into horizontal boring machine, floor boring and milling machine, diamond boring machine and coordinate boring machine and other types
●Horizontal boring machine: It is the most widely used boring machine with the widest performance, suitable for small batch production and repair units.
● Floor boring machine and floor boring and milling machine: The feature is that the workpiece is fixed on the floor platform, which is suitable for processing workpieces with large size and weight, and is used in heavy machinery manufacturing plants.
●Diamond boring machine: use diamond or cemented carbide tools to bore holes with high precision and low surface roughness at a small feed rate and high cutting speed. It is mainly used in mass production.
Coordinate boring machine: with precise coordinate positioning device, it is suitable for processing holes with high precision requirements in shape, size and hole distance, and can also be used for marking, coordinate measurement and calibration, etc., used in tool workshops and small and medium batch production middle. Other types of boring machines include vertical turret boring and milling machines, deep hole boring machines and boring machines for repairing automobiles and tractors.
Application of Single Arm Boring Machine in Machining Motor Frame
The single-arm boring machine is mainly used for the rough and finish machining of the motor base, including: inner bore, two-end spigot and end face turning, and similar box parts can be processed on this machine tool.
The machine tool adopts horizontal double support structure, which is composed of bed, spindle box, radial feed box, longitudinal feed box, bell rod, head, movable, fixed support, lubricating station and electrical control part and other components. During processing, the rotation of the cutter on the front head is the main movement, and the cutter has two kinds of feed movements, longitudinal and radial, to complete the key hole and the end face of the car. The rod is nitrided, and the flat guide rail of the bed is made of inlaid steel guide rail to enhance its wear resistance and precision retention. By installing different fixtures and pad irons, it is suitable for processing different center height frames.
