Problems solved by technology

[0002] In mechanical processing, chips are not easy to get rid of during the cutting process, and the chips are easy to tangle. The chips generated by the existing cutting tools are blocked by the end face of the tool shaft, so it is not easy to get rid of them smoothly, and even stick to the tool body due to high temperature, which seriously hinders the cutting process. The heat dissipation of the cutter body shortens the life of the cutter body, and the chips adhering to the cutter body tend to scratch the surface of the workpiece, which cannot make the processed surface smooth, especially after the first processing of gas and liquid valves. The surface of the workpiece needs to be smooth and free of scratches during the second processing. Due to the complex internal structure of the valve, ordinary tools cannot complete this work.

Abstract

The invention belongs to the field of cutting tools and particularly relates to a compound reamer for a valve port. The compound reamer for the valve port comprises a reamer plate, a reamer rod and a reamer head. The reamer head comprises a first-order reamer head, a second-order reamer head, a third-order reamer head, a fourth-order reamer head and a fifth-order reamer head. The reamer plate is connected with the reamer rod through an arc surface. The first-order reamer head is provided with a cooling liquid outlet. The reamer plate is provided with a cooling liquid inlet pipe. A cooling liquid channel is formed inside the reamer rod and the reamer head. The cooling liquid channel is communicated with the cooling liquid inlet pipe and the cooling liquid outlet pipe. The compound reamer for the valve port has the advantages of being simple and practical in structure, and can be processed and formed one time when reaming and cooled real time so that the service life of the reamer is prolonged.
