Automatic dynamic balance boring cutter and using method

Abstract

The invention relates to an automatic dynamic balance boring cutter which comprises a boring cutter body. The boring cutter body is internally provided with a cutter rod adjusting mechanism, a dynamicbalance mechanism and a locking mechanism, the cutter rod adjusting mechanism comprises a dial, a fine tuning screw and a sliding cutter clamp, the dial is fixedly connected with the fine tuning screw, the sliding cutter clamp is arranged outside the fine tuning screw in a sleeving manner and is matched with the fine tuning screw, and a cutter rod is arranged at the end of the sliding cutter clamp and is provided with a blade; the dynamic balance mechanism comprises a transmission gear, a balance screw and a balance cutter clamp, the end of the balance screw is connected with the boring cutter body, the balance cutter clamp is arranged on the outer ring of the balance screw in a sleeving manner and is matched with the balance screw, and the transmission gear is arranged between the balance screw and the fine tuning screw; and the locking mechanism is arranged between the cutter rod adjusting mechanism and the dynamic balance mechanism. According to the automatic dynamic balance boringcutter, during fine adjustment of the boring hole size, the dynamic balance mechanism is automatically adjusted, the gravity of the boring cutter is completely coincident with a rotating shaft, the boring hole size adjusting speed is increased, the adjusting accuracy of the dynamic balance mechanism is increased, and the boring cutter machining efficiency is improved.

Description

technical field [0001] The invention relates to the field of machining tools, in particular to an automatic dynamic balancing boring tool and a using method thereof. Background technique [0002] The automatic dynamic balance boring tool is a tool that drives the balance system and the fine-tuning device to finish the hole. With the rapid development of industrial technology, people have higher and higher requirements for the inner hole and processing efficiency. The rotating speed can obtain better inner hole surface quality and higher processing efficiency. With the increase of tool speed, the requirements for tool dynamic balance are getting higher and higher. The traditional dynamic balance adjustment boring tool needs to adjust the dynamic balance system separately after adjusting the size. The process is cumbersome and very inconvenient. Insufficient adjustment accuracy of the dynamic balance system causes the center of gravity of the boring tool to not coincide with ...

With the increase of tool speed, the requirements for tool dynamic balance are getting higher and higher. The traditional dynamic balance adjustment boring tool needs to adjust the dynamic balance system separately after adjusting the size. The process is cumbersome and very inconvenient. Insufficient adjustment accuracy of the dynamic balance system causes the center of gravity of the boring tool to not coincide with the axis of rotation. When the boring tool rotates, it is easy to cause the boring tool to be thrown out, which seriously affects the safety of users.

In order to ensure safety and prevent the boring tool from being thrown out, it is necessary to strictly control the rotating speed of the boring tool, which affects the processing efficiency
