Abstract

The invention discloses a portable vibration auxiliary drilling device, a hole making method and a processing signal detecting method, which belongs to the field of vibration auxiliary drilling processing. The device comprises a shell (1), a fixed inner shell (3), a movable inner shell (5), a conductive ring (8), a vibration unit (6), and a motor (12). The portable vibration auxiliary drilling device, a hole making method and a processing signal detecting method has advantages that: (1) adjusting the pre-tightening force, the size of the rear cover plate and the intermediate block to adjust the vibration frequency of the device, by using the piezoelectric ceramic driving mode, thereby obtaining excellent drilling performance; (2) real-time monitoring the speed, feed and the number of holesin the drilling process, to achieve intelligent processing, and reducing the adverse effects of human factors on the processing quality; (3) the mobile inner shell structure eliminates the interference signal during non-processing, and the signal detection is more accurate; (4) using a universal tool mounting structure to realize rapid tool change, which is simple and easy to implement in practical applications.

Description

technical field [0001] The invention belongs to the field of vibration-assisted drilling, in particular to the field of a portable vibration-assisted drilling device, a hole-making method, and a processing signal detection method. Background technique [0002] At present, hand drill holes are widely used in aviation, aerospace and other fields to solve the problem of hole making in areas that are difficult for automatic drilling equipment to reach. However, there are many problems in traditional mechanical hole making, such as serious heat generation, excessive cutting force, cutting tools Wears out faster etc. In the hole making of difficult-to-machine materials, traditional mechanical hole making has problems such as poor processing quality and low processing efficiency. Relevant studies have shown that vibration-assisted cutting has obvious advantages in reducing cutting force, improving processing quality, and prolonging tool life. Therefore, this paper combines vibrati...
