Abstract

The utility model relates to a turnover mechanism of a seamless steel tube inner hole sharpening machine. The turnover mechanism of the seamless steel tube inner hole sharpening machine is installed at one side of a shaft roller support of a steel tube workpiece of a sharpening machine. The turnover mechanism of the seamless steel tube inner hole sharpening machine is characterized in that two supports are symmetrically and fixedly arranged in the coaxial direction at the two sides of the shaft roller support where the steel tube workpiece is erected, the two supports are respectively hinged to a swing arm, a synchronous swing rod is fixedly arranged at the outer ends of the two swing arms, the inner end of each swing arm is located below the steel tube workpiece, a hydraulic cylinder is fixedly arranged below one end portion of the inner end of each swing arm, and the extending end of the hydraulic cylinder and the inner end of each swing arm are fixedly arranged. The hydraulic cylinder is adopted by the turnover mechanism of the seamless steel tube inner hole sharpening machine so that synchronous turnover can be achieved, the work efficiency can be effectively improved, and the labor intensity of workers can be relieved.

Description

A kind of seamless steel pipe inner bore sharpening machine switching mechanism

Technical field

The utility model belongs to field of metallurgy, relates to the manufacture of seamless steel pipe, especially a kind of seamless steel pipe inner bore sharpening machine switching mechanism.

Background technology

The seamless steel pipe application is comparatively extensive, especially in oil field, uses as oil pipe.At present, seamless steel pipe, after processing shell, at the inner surface of seamless steel pipe, form certain burr or impurity, and often there is certain ovality in the internal diameter of seamless steel pipe, and namely the endoporus axiality of seamless steel pipe has deviation.When deviation acquires a certain degree, can cause inlet pipe equipment to enter.The burr and the impurity that in order to overcome the seamless steel pipe inner bore surface, exist, and whether the axiality of seamless steel pipe surpasses the axiality of regulation, existing way normally adopts manually to be goed deep into seamless steel pipe inner bore with hairbrush and carries out reciprocal wiper, to remove burr and the impurity of bore area; The check of axiality is undertaken by range estimation.Manually carry out above-mentioned work and cause operating efficiency comparatively low, quality inspection has certain uncertainty.

Except manually carrying out the problem of reconditioning existence, the steel pipe workpieces after reconditioning need to by manually by steel pipe movement to the finished product frame, labour intensity is larger, inefficiency.

By retrieval, not yet find the patent document relevant to the utility model application.

The utility model content

The purpose of this utility model is to overcome the deficiency existed in above-mentioned technology, and a kind of seamless steel pipe inner bore sharpening machine switching mechanism of the undercarriage that automatically steel pipe workpieces overturn is provided.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of seamless steel pipe inner bore sharpening machine switching mechanism, this mechanism is arranged on the beaming roller frame side of the steel pipe workpieces of sharpening machine, it is characterized in that: at coaxial two supports that are fixed with symmetry of beaming roller frame side of frame dress steel pipe workpieces, all hinge fills a swing arm on these two supports, the outer end of two swing arms is fixedly mounted with a synchronous fork jointly, the inner end of this swing arm is positioned at the steel pipe workpieces below, below the end of this swing arm inner end, is fixedly mounted with a hydraulic cylinder, and the external part of this hydraulic cylinder and swing arm inner end are fixedly mounted with.

And, described sharpening machine comprises travelling car, beaming roller motor, vehicle motor, reconditioning axle, travelling car is walked in orbit by wheel, wheel passes through chain drive by the vehicle motor be packed in travelling car, the beaming roller motor is packed in plane on travelling car, the coaxial affixed reconditioning axle of its output shaft, with the coaxial travelling car one side interval of track, be fixedly mounted with a plurality of beaming roller framves, the equal frame of reconditioning axle and steel pipe workpieces is contained on the beaming roller frame, and the reconditioning axle enters in the endoporus of steel pipe workpieces and carries out coaxial reconditioning under the driving of travelling car.

Advantage of the present utility model and beneficial effect are:

The switching mechanism of this sharpening machine adopts hydraulic cylinder synchronously to overturn, and can effectively increase work efficiency, and alleviates workman's labour intensity.
