Abstract
Description
technical field
[0001] The invention relates to the technical field of machining, in particular to a cylindrical hole boring device. Background technique
[0002] For the boring of ultra-long and narrow cylindrical holes that require on-site processing, the existing equipment cannot meet the requirements, so corresponding on-site processing devices must be designed. Due to the limited size of the part to be processed, the diameter of the boring bar cannot be increased infinitely. If the length-to-diameter ratio of the boring bar is artificially increased in order to process cylindrical holes, the strength and rigidity of the boring bar will inevitably be greatly weakened. The boring bar with boring device is divided into front, middle and rear three bearing supports and a dynamic support. Since four external force support points are added to such a slender boring bar, no matter which external force support point has a difference during clamping and correction, it will lead ...
