Description

Technical Field

[0001] This utility model belongs to the field of cutting tool technology, and in particular relates to a deep hole composite boring tool. Background Technology

[0002] Machine repair shops disassemble and install a large number of motor and gearbox couplings every year. Due to the heavy loads they operate under during daily work, the couplings often become deformed, uneven, and have burrs after disassembly. To ensure proper reinstallation, the couplings need to be repaired. However, because these couplings are too heavy for lathes to machine, they are currently repaired manually using a straight grinder and sandpaper, resulting in inconsistent quality. Utility Model Content

[0003] The purpose of this utility model is to provide a deep hole composite boring tool to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows: A deep hole composite boring tool includes a tool holder and a tool head detachably connected to the tool holder. The tool holder is composed of a fixed shank and a connecting shank. The side wall of the connecting shank away from the fixed shank is provided with an insertion port for sliding connection with the tool head.

[0005] Preferably, the fixing handle and the connecting handle are arranged in a straight line, and the fixing handle and the connecting handle are fixedly connected.

[0006] Preferably, the side wall of the fixing handle away from the connecting handle is provided with a mounting hole.

[0007] Preferably, the size of the insertion port matches the size of the cutting head.

[0008] Preferably, a threaded hole is provided at the middle part of the connecting handle away from the fixed handle. The threaded hole is connected to the socket. A locking screw is threaded into the threaded hole. The end of the locking screw extends into the socket and contacts the side wall of the blade.

[0009] The deep hole composite boring tool of this utility model has the following advantages:

[0010] This utility model has a simple structure, is easy to operate, and has low manufacturing cost. It can meet the repair needs of various couplings and ensures the repair quality. The sliding connection between the cutter head and the socket makes it easy to adjust the length of the cutter head extension, thereby facilitating the adjustment of the cutter length according to the diameter of the coupling. This not only saves money by repairing and utilizing old parts, but also ensures smooth production. Attached Figure Description
