During the processing of mechanical parts, the deformation of parts is very likely to occur. In the practical processing process, the shape change of mechanical parts processing is inevitable. However, we must control the range of mechanical deformation of the parts. The internal force condition of mechanical parts processing is an important factor affecting the processing accuracy. During the mechanical processing, affected by the four-jaw chuck of the lathe, some components will be affected by the clamping force. This control effect with centripetal force can promote the reasonable processing of parts by the machine. During the processing of mechanical parts, it is also affected by the internal radial force. In order to ensure the tightness of mechanical parts, mechanical parts processing must control the size of mechanical cutting and ensure the increase of the overall clamping force of the machine, so as to meet the requirements of the actual mechanical parts processing work.
After the chuck jaws are loosened, there is a large difference in shape between the processed mechanical parts and the original mechanical parts, and a relatively large shape deviation occurs, which generally appears in an elliptical shape. In order to avoid the rough deformation during the processing of mechanical parts, it is necessary to carry out the heat treatment of mechanical parts, so as to effectively control the mechanical deformation. During the finish turning operation, it is necessary to do a good job in the clamping of components, carry out the relevant grinding processing links, and control the finish turning reference surface. During the subsequent processing of mechanical parts, it is necessary to control the deviation of boring the inner hole on the boring machine to meet the requirements of the actual work.
Effective positioning and processing control need to be carried out on the grinding surface. In the actual construction of mechanical parts processing, some finish turning boring machines are also inaccurate. This machine tool processing method is not conducive to the control of the size and accuracy of mechanical parts processing and is difficult to meet the requirements of the expected drawings. In order to solve this problem, it is necessary to apply new processing methods and do a good job in the processing of mechanical parts with heat treatment and finish turning to meet the requirements of the actual work.
A series of part deformation conditions will also occur after the heat treatment of mechanical parts processing. For some thin and light mechanical components with a relatively small length, after a series of processing and heat treatment, if they are placed for a period of time, a bending change in the shape of a straw hat may occur. This kind of bending is called straw hat-shaped bending. Through the implementation of experimental testing work, the plane of this part changes greatly and has a relatively long radius. The deformation of some parts is caused by their own internal stress. In order to meet the requirements of the actual work, it is necessary to control the internal stress, maintain its balanced state, and improve the overall stability of the components.
