Embodiment approach 1

[0020] I. Clamping of the workpiece

[0021] combined with figure 1 , specifically to further elaborate how the round tube part 7 is clamped. Firstly, the φ108×4 3m long stainless steel round tube part 7 with an inner cavity of oxide skin passes through the stator type magnetic field generator 5 and is positioned and clamped on the V-shaped positioning block 11, and the center height of the round tube part 7 is adjusted by the adjusting nut 10 Make it coaxial with the magnetic field generator 5 to complete the clamping of the workpiece;

[0022] II. Magnetic rough honing

[0023] combined with figure 1 , attached figure 2 , specifically to further elaborate how the inner surface of the round tube part 7 realizes the magnetic rough honing. Put the rotor honing head 6 equipped with 80# brown corundum grinding block into the inner cavity of the round tube part 7, the specific operation is as follows: turn the elastic rod 12, the top spring 13 is pressed, the grinding block ...

Abstract

The invention relates to long round pipe inner surface processing equipment and a process thereof, belonging to the technical field of special processing. The invention is characterized in that a rotary magnetic field produced by a stator type magnetic field generator and a rotor honing head in the inner cavity of a round pipe workpiece form magnetic action, the rotor honing head rotates and moves along with the rotary magnetic field under the magnetic action, so that the rotor honing head and static workpiece move relatively in non-mechanical driving way, rough machining and finish machining of round pipe inner surface can be realized by adopting different rotor honing heads, and especially efficiency is high and processing effect is good in processing of the inner hole surface of a round pipe part with higher length and larger diameter. The invention has the advantages that rough machining and finish machining of inner hole surface of round pipe part with higher length and larger diameter are realized, the problem that inner surface processing of long round pipe which is not suitable to high speed rotation is difficult owning to part structure particularity in actual production can be completely and effectively solved, equipment has simple structure and low cost, and the technology has higher application value.

Description

technical field [0001] The invention discloses a process for processing equipment for the inner surface of a long circular tube, which belongs to the technical field of special processing. Specifically, it involves motor design technology, electromagnetic technology, rotor honing head manufacturing technology, grinding technology, vibration technology, etc. The invention is suitable for processing the inner surface of long circular tube workpieces. Background technique [0002] With the improvement of production technology, people have higher and higher requirements for the surface quality of parts. For example, in the semiconductor production process, there are high requirements for the surface quality of the inner hole of stainless steel tubes that transport various high-purity gases, especially in actual production. There are also some long round pipe parts (such as logistics pipelines), which are not suitable for high-speed rotating motion due to the particularity of th...
