Description

Technical Field

[0001] The utility model relates to an inner conductor concentricity processing mechanism, belonging to the technical field of concentricity processing. Background Art

[0002] In order to ensure the accuracy during the processing of the inner conductor, the concentricity needs to be determined during the processing to ensure that the outer circle and the center hole are concentric, which is convenient for subsequent processing. Traditionally, the concentricity of the inner conductor is processed by the processing master manually marking, which will cause errors during processing. In addition, the processing is now completed on one end and then on the other end. In this way, the concentricity cannot be maintained, errors are prone to occur, resulting in scrapped workpieces and reduced processing efficiency.

[0003] The existing inner conductor concentricity processing mechanism still has some problems during use. The two ends cannot be processed at the same time. After one end is processed, it is replaced and processed at the other end. This will result in a large concentricity error, which reduces the product qualification rate. The tool cannot adjust itself during movement, and the work efficiency is low. Summary of the invention

The concentric tube is rotated under the drive of a motor, and a cylindrical object fixed on the concentric tube also rotates. The drill bits at both ends of the concentric tube clamp the rotating object to perform concentricity processing, so as to solve the problems raised in the above-mentioned background technology.
