At present, length is mainly contained two kinds in the processing mode of the above steel pipe internal-surface of 3m both at home and abroad:
1, ball blast or blasting treatment: utilize gases at high pressure or special electronic ramming head with high rigidity shot or steel sand high-speed projectile in steel pipe internal-surface, to reach the effect of cleaning steel tube surface, but this kind method can only be handled the iron scale and the corrosion on surface, can not reach the usefulness of removing blemish and controlling dimension.
2, reconditioning is handled: utilize the emery wheel that rotates at a high speed to go deep into steel tube inner hole and carry out reconditioning, owing to be subjected to mechanically operated restriction, also under test both at home and abroad at present to the endoporus reconditioning of overlength degree more than 3 meters and the less steel pipe of diameter.In Machine Design,, suitable solution is not also found in the design of minor diameter overlength degree high speed revolving rod at present both at home and abroad owing to be subjected to the restriction of accessory size and intensity.
Summary of the invention
Technical problem to be solved in the utility model is: at above-mentioned the deficiencies in the prior art, a kind of minor diameter overlength degree steel tube inner hole reconditioning drive mechanism is provided, can overcome the difficulty on the machine driving designing technique in the minor diameter overlength degree steel pipe reconditioning process, the drive disk assembly size is dropped to minimum, can satisfy simultaneously the requirement of high speed transmission again, reach the little rod member that the overlength degree is rotated at a high speed and stretch into the purpose that the steel pipe internal-surface reconditioning is carried out in minor-diameter steel-tube inside.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of minor diameter overlength degree steel tube inner hole reconditioning drive mechanism, comprise emery wheel, main shaft, reach high-speed electric expreess locomotive, one end of this main shaft is connected with emery wheel by emery wheel cover, gland, clamp nut, be characterized in: also comprise Bowden cable, the other end of this main shaft is connected with an end of Bowden cable by joint, and the other end of this Bowden cable is connected with high-speed electric expreess locomotive by shaft coupling with joint.
The outside of described Bowden cable has additional rubber steel flat tube, and this rubber steel flat tube is fixed on the metal tube by expansion type chucking cover; This main shaft outside is provided with collar bush between emery wheel and Bowden cable, an end and the nut of this collar bush are spirally connected, and the other end and this expansion type chucking cover are spirally connected, and are provided with 3 radial ball bearings on this main shaft in collar bush.
2 radial ball bearings in described 3 radial ball bearings are near this nut, and the centre is provided with the spacer ring cover, and the 3rd radial ball bearing is located at the end that main shaft and Bowden cable join.
The utility model compared with prior art has following characteristics:
1, adopts Bowden cable to do the transmission carrier, avoided in the Machine Design high speed rotating member the requirement of part concentricity.
2, owing to adopt tiny Bowden cable to do power transmission shaft, effectively reduced accessory size, the I of whole transmission device diameter is designed into φ 40mm, thereby hole dimension carries out surface treatment work in the steel duct of φ more than 50 in can extending into.
3, whole drive mechanism is simply compact, is convenient to safeguard, can reduce maintenance cost according to the different recyclings of reconditioning steel pipe length after flexible axle damages.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a main shaft portion assembling schematic diagram of the present utility model.
The specific embodiment:
Referring to Fig. 1 and Fig. 2, the utility model is a kind of minor diameter overlength degree steel tube inner hole reconditioning drive mechanism, comprise emery wheel 1, main shaft 2, Bowden cable 3, reach high-speed electric expreess locomotive 4, one end of this main shaft 2 is connected with emery wheel 1 by emery wheel cover 5, gland 6, clamp nut 7, the other end is connected with an end of Bowden cable 3 by joint 8, the other end of this Bowden cable 3 is connected with high-speed electric expreess locomotive 4 by shaft coupling 10 with joint 9, forms compactness thus and is in transmission connection.For avoiding Bowden cable 3 to produce vibrations in the high speed rotary course, a rubber steel flat tube 11 that is a bit larger tham its diameter is set up in the outside of this Bowden cable 3, and this rubber steel flat tube 11 is fixed in metal tube 13(by expansion type chucking cover 12 can adopt steel pipe) on.These main shaft 2 outsides are provided with collar bush 14 in emery wheel 1 and 3 of Bowden cables, one end and the nut 15 of this collar bush 14 are spirally connected, the other end and expansion type chucking cover 12 are spirally connected, consider the axial and radial load of emery wheel in high speed rotary grinding process, in collar bush 14, be provided with 3 radial ball bearings 16 on this main shaft 2, wherein 2 radial ball bearings 16 are near this nut 15, this nut 15 can guarantee that radial ball bearing 15 can not deviate from, 16 of these 2 radial ball bearings separate with spacer ring cover 17, and the 3rd radial ball bearing 16 is located at the end that main shaft 2 and Bowden cable 3 join.
