Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] Such as figure 1 , figure 2 As shown, an internal grinding machine for steel pipes according to the present invention includes rails fixed on the ground, two rails are arranged in parallel, and two opposite rails are arranged on the rails along the extending direction of the rails. The distance between the first trolley 1 and the two first trolleys 1 can be adjusted at will to meet the support requirements of steel pipes of different lengths. The firs...

Abstract

The invention discloses an internal grinding machine for steel pipes, which comprises a track, a first trolley and a second trolley arranged on the track, the first trolley is provided with supporting wheels for supporting and driving the steel pipe to rotate, and the second trolley is provided with The lifting column, the connecting piece, and the sleeve connected with the connecting piece, the sleeve is provided with a first rotating shaft, the first rotating shaft is connected with a worm, the worm is meshed with a worm wheel, the worm wheel is threaded on the second rotating shaft, and the second rotating shaft The shaft is connected to the sleeve through a parallel beam sensor, and a clamping mechanism is also arranged in the sleeve; the axis of the grinding wheel of the present invention is perpendicular to the axis of the first rotating shaft, and the first rotating shaft is only subjected to the bending moment on the vertical plane, and It will not be subjected to the bending moment on the horizontal plane, and under the action of the support of the sleeve, the bending of the first rotating shaft on the vertical plane is avoided; and the parallel beam sensor can detect the pressure of the grinding wheel on the inner wall of the steel pipe, so that the grinding wheel The inner wall of the steel pipe has a suitable amount of grinding to avoid excessive pressure affecting the size of the inner diameter of the steel pipe.

Description

technical field [0001] The invention belongs to the technical field of steel pipe production equipment, and relates to an internal grinding machine for steel pipes. Background technique [0002] The grinding of existing steel pipes generally uses manual grinding or simple mechanical grinding head grinding, which has low efficiency, high manual labor intensity, and obviously insufficient working conditions, which cannot meet the requirements of the era of high efficiency and high quality. In addition, the inner surface of steel pipes produced generally has defects such as scars, inner folds, thread lines, oxide scales, etc., which need to be polished. Steel pipes with smaller diameters can be processed by deep hole drilling machines, but the diameter is larger. Large steel pipes are more troublesome. [0003] At present, for the steel pipe internal grinding machine with larger diameter, it generally includes a track arranged on the ground, and a support trolley that can supp...
