Inner reamer and machining method of water pump circulating pipe

Abstract

The invention relates to the technical field of cutters, and discloses an inner reamer and a machining method of a water pump circulating pipe. The inner reamer comprises a reamer bar, wherein a circular deep groove is formed in the upper surface of the reamer bar, a plurality of T-shaped grooves uniformly distributed are formed in the outer wall of the reamer bar, arc-shaped plates are movably connected to the groove walls of the T-shaped grooves, the outer walls of the arc-shaped plates are fixedly connected with blades, the outer wall of the reamer bar is fixedly sleeved with a limiting ring, threads are formed in the outer wall of the reamer bar, the outer wall of the reamer bar is in threaded connection with a fixing nut, the top end of the outer wall of the reamer bar is movably connected with a connecting mechanism, and the top end of the connecting mechanism is fixedly connected with a cooling mechanism. According to the inner reamer and the machining method of the water pump circulating pipe, only the damaged parts need to be replaced when the blades are damaged, the whole inner reamer does not need to be replaced, so that the unnecessary waste is avoided, and meanwhile, the unnecessary loss is avoided; and the replacement efficiency of the inner reamer can be effectively improved, the replacement process is time-saving and labor-saving, and the service life of the inner reamer can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of cutters, in particular to a processing method for an internal reamer and a water pump circulation pipe. Background technique [0002] The reamer has one or more cutter teeth, which are used to remove the thin metal layer on the machined surface of the hole. The hole processed by the reamer can obtain accurate size and shape. The reamer is used to ream the drilled workpiece. The processed hole is mainly to improve the machining accuracy of the hole and reduce its surface roughness. It is a tool for finishing and semi-finishing the hole. The machining allowance is generally small. It is used to process the reamer of the cylindrical hole. Knives are more commonly used, and the reamer used to process tapered holes is a tapered reamer, which is less used. According to the use situation, there are hand reamers and machine reamers, and machine reamers can be divided into straight shank reamers and tapered shank...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a processing method for the inner reamer and the water pump circulation pipe, which can only replace the damaged part when the blade is damaged, and does not need to replace the entire inner reamer, avoiding unnecessary waste, and at the same time Avoiding unnecessary losses can also effectively improve the efficiency of the replacement of the inner reamer, and the replacement process saves time and effort, and can effectively guarantee the service life of the inner reamer, which solves the need to replace the entire inner reamer when the edge of the inner reamer is damaged. At the same time, the installation process of the internal reamer is cumbersome and inconvenient, time-consuming and laborious, which affects the efficiency of the replacement of the internal reamer, and the blade is rubbed when the internal reamer is working. Affects the high temperature, and it is easy to damage the edge of the inner reamer in a high-temperature environment for a long time, which affects the service life of the inner reamer
