Description

A processing machine tool with a flanged bearing ring and its processing technology

technical field

Background technique

Bearing is an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Therefore, bearings are widely used in various mechanical equipment .

The flange four-point contact automobile bearing is an important transmission bearing in automobiles. As shown in Figure 7, the bearing ring of the bearing is a ring with a special shape, and a ring of flange is provided in the center of the outer wall (the bearing is also Hence the name), the side of the flange and the outer wall of the bearing ring need to be at 90 degrees, and both ends of the outer wall of the bearing ring must have arc-shaped protrusions. Pin machining presents challenges. In turning processing, the commonly used feeding methods are forward feeding (feeding directly to the workpiece) and lateral 90-degree feeding (feeding along the length of the machine bed, and the cutter head is perpendicular to the workpiece). The infeed cutting method can form a flange, but due to the presence of arc-shaped protrusions at both ends of the outer wall of the bearing ring, the forward infeed cutting method cannot meet the processing requirements. Currently, the 90-degree lateral infeed is used. However, in the actual cutting process, it was found that in the cutting mode of 90-degree lateral feed, the 90-degree angle on the side of the flange cannot be formed 100% perfectly, and there is a problem of retracting the tool (the blade will move along the workpiece when retracting the tool). The processing surface exits, and there is a probability of collision between the blade and the flange side), which is prone to chipping, and the flange side will also have defects such as chipping and edge cutting.

Although the existing turning machine tools have achieved a certain degree of automation, manual operations are still required in terms of workpiece installation and disassembly, which destroys the continuity of production and greatly restricts production and processing efficiency. There is a need for further automation of turning machine tools need.
