Embodiment 1

[0025] Such as figure 1 , 2 As shown, a turning device for multi-start spiral grooves in inner holes of cylindrical parts includes a milling cutter body and a plurality of milling blades 3 .

[0026] The milling cutter body consists of a milling shank 1 and a milling head 2 connected to each other.

[0027] The milling cutter bar 1 has a stepped shaft structure, and a threaded blind hole 5 is formed on the end face away from the milling head 2; the threaded blind hole 5 is used to realize the threaded connection between the milling cutter bar 1 and the output shaft of the machine tool motor. The milling cutter bar 1 is composed of a connecting section, a middle section and a tail section which are connected in sequence. The tail section is a truncated circular structure whose diameter gradually decreases from the head end to the tail end, and an annular groove is formed on the outer circumference of the small diameter end. The connecting section is connected with the milling...

Abstract

The invention discloses a turning device used for a barrel type part inner hole multi-end spiral groove. The turning device comprises a milling cutter and multiple milling blades. The milling cutter is formed by a milling cutter rod and a milling cutter bit which are connected. The milling cutter rod is of a stepped shaft structure, and a threaded blind hole is formed in the end face, away from the milling cutter bit, of the milling cutter rod. The milling cutter bit is of a disc-shaped gear structure, and each tooth of the milling cutter bit is provided with one milling blade. The turning device suitable for turning of the barrel type part inner hole multi-end spiral groove on a cyclone milling machine is provided, the number of the cutter bit is increased, machining is similar to milling, the turning problem about turning of part inner hole spiral grooves is solved well, the machining time of thread turning can be reduced, machining efficiency can be improved, the part machining precision can be ensured, and design requirements can be met.

Description

technical field [0001] The invention belongs to the field of turning processing, and in particular relates to a turning device for multi-head spiral grooves in inner holes of cylindrical parts. Background technique [0002] The multi-head spiral groove turning of the inner hole of the cylindrical part needs to be turned to process the spiral groove in the inner hole of the cylindrical part with a thickness of about 8mm. After processing, the thinnest part of the cylindrical wall is about 2.2mm. Precision machining of cylindrical parts. The traditional turning method is to turn the thread one by one with the turning tool, which takes a long time to process and low processing efficiency. Contents of the invention [0003] The present invention is proposed in order to overcome the shortcomings of long processing time and low processing efficiency of multi-head spiral grooves in the inner holes of cylindrical parts in the prior art. Turning device. [0004] The present inve...
