Description

Technical Field

[0001] The utility model belongs to the technical field of roller burnishing machines, and specifically relates to a numerical control cutting and roller burnishing machine. Background Art

[0002] At present, with the rapid development of science and technology, deep hole finishing usually has two processing technologies: drilling, rough boring, semi-finishing boring, finishing boring, rolling when the aspect ratio is 1.5-10, and drilling and honing when the aspect ratio is greater than 10. Processing a finished product requires multiple processes, multiple tools, and continuous tool replacement. Although the quality is relatively stable, the processing efficiency is low and the cost is high. The existing scraping and rolling machine uses a combination of tools to process the cylinder barrel of the oil cylinder. Rough boring, scraping, rolling and other processing procedures are completed at one time. The processing efficiency can reach more than ten times that of the traditional grinding method. Therefore, it is increasingly favored by manufacturers. The inner hole with a diameter of 30 is processed and the surface roughness is Ra3.2 or below, which fully meets the reserved surface roughness required for rolling processing. At the same time, the existing low-plasticity rolling can be completed together with the cutting processing on ordinary machine tools or machining centers. A simple process can be used to achieve a deeper residual stress distribution and less cold work hardening. The scraping and rolling machine uses a combination of tools to process the cylinder barrel of the oil cylinder. Rough boring, scraping, rolling and other processing procedures are completed at one time. The processing efficiency can reach more than ten times that of the traditional grinding method. Therefore, it is increasingly favored by manufacturers.

The top plate 11 is fixedly connected to the corresponding positioning rods 10. A cutter head 13 is installed on one side of the top plate 11, and a driving wheel 12 is rollingly connected to the top plate 11. The top plate 11 is pressed into the inner hole of the workpiece through the driving wheel 12, so that the boring bar 5 can be stably transmitted in the workpiece, thereby driving the cutter head 13 to cut the inner hole of the workpiece. The setting of the positioning rod 10 can limit the top plate 11.

[0028] Reference Figure 2 A movable plate 14 is slidably connected to the boring bar 5. The cross-section of the boring bar 5 is fan-shaped and a thread is provided on the arc surface. Four symmetrically arranged hinged rods 15 are rotatably connected to the movable plate 14.
