End face ring-type deep groove machining cutter

Abstract

The invention discloses an end face ring-type deep groove machining cutter which comprises a cutter body and a blade. The cutter body comprises a cutter handle matched with a machine tool tailstock hole and a barrel-shaped blade seat connected with the cutter handle, one end of the blade seat is fixedly connected with the cutter handle, the tail end of the other end of the blade seat is provided with a notch, and the barrel wall, corresponding to the notch, is fixedly connected with the blade. According to the end face ring-type deep groove machining cutter, the structure is simple, due to the fact that the large-area notch is formed in the barrel-shaped blade seat, the chip removing speed and the chip retreating speed are increased, and the production efficiency is improved; meanwhile, the wall thickness of the barrel-shaped blade seat is decreased, so that the barrel-shaped blade seat does not make contact with a workpiece, the energy loss in the machining process is reduced, and heat generated through friction is reduced; meanwhile, cooling liquid can be added from a gap between the barrel-shaped blade seat and the groove wall of a workpiece deep groove if necessary, the temperature of a formed workpiece is lowered, the cooling time is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to mechanical processing technology, in particular to a tool for processing end face ring-shaped deep grooves. Background technique [0002] In the process of mechanical processing, the processing of annular deep grooves is often encountered. When processing with a turning tool, because the depth of the deep groove is large, the turning tool is long and has poor rigidity, which is easy to damage the turning tool. In order to solve the above technical problems, Chinese patent CN200942431 discloses a ring-shaped deep groove turning tool, which includes a tool handle and at least one cutter head, and is characterized in that: said tool handle is a drill sleeve with a tapered shank, the tapered The shank is fastened to the back of the drill sleeve, and the cutter head is embedded in the front end of the drill sleeve. The width of the cutter head is equal to the width of the processed annular deep groove, and the distance from the inne...

AI Technical Summary

Problems solved by technology

However, during the use of this patented product, due to the reasonable design of the flute, the chip cannot be removed in time, especially in high-speed machining, which seriously affects the production efficiency

In addition, the width of the cutter body of this patent is consistent with the width of the deep groove processed with the belt, which causes the blade and the drill sleeve carrying the blade to generate high temperature due to friction during high-speed machining, the heat dissipation efficiency is slow, and the coolant cannot directly contact the blade, not only It is easy to cause safety production accidents, and also reduces the service life of each equipment

At the same time, the cutter head provided by Chinese patent CN200942431 protrudes from the drill sleeve too long, which affects the rigidity of the cutter head
