Synchronous grinding device for inner surface and outer surface of steel pipe end

Abstract

The invention relates to a synchronous grinding device for the inner surface and the outer surface of a steel pipe end. The synchronous grinding device comprises an axial feed mechanism and a grinding mechanism driven by the axial feed mechanism to move in the axial direction. The synchronous grinding device is characterized in that the grinding mechanism is a synchronous grinding mechanism and comprises a grinding motor, an inner grinding component, an outer grinding component and a steel pipe rotating roller mechanism; the inner grinding component and the outer grinding component are driven by the grinding motor to rotate synchronously, and the grinding motor drives a grinding head of the inner grinding component and a grinding head of the outer grinding component to rotate; the steel pipe rotating roller mechanism drives chain transmission through a geared motor and drives a roller mechanism to make a steel pipe to rotate in the circumferential direction. According to the synchronous grinding device for the inner surface and the outer surface of the steel pipe end, as the scheme that grinding shafts arranged in two independent swing shaft seats are driven in a single-motor dual-drive mode to achieve synchronous grinding actions, the feed motion of the grinding heads is achieved by driving a nut and a lead screw through the geared motor, and circumferential rotation of the steel pipe is achieved by driving rollers is adopted, the inner surfaces and the outer surfaces of the steel pipe ends with different outer diameters and wall thicknesses can be ground synchronously, grinding quality is improved, labor efficiency is enhanced, auxiliary time is shortened, and production cost is lowered.

Description

technical field

[0001] The invention relates to a steel pipe grinding device, in particular to a steel pipe end inner and outer surface synchronous grinding device. Background technique

[0002] In order to detect the internal and external surface defects of the steel pipe end, the surface must be ground. In the prior art, there is a device for independently grinding the inner or outer surface of the steel pipe to realize full-length or partial grinding of the steel pipe surface. There is also a steel pipe inner and outer surface grinding equipment in the prior art, which is specially used to precisely grind the inner and outer surfaces of steel pipes to obtain high-precision dimensions. The cost is too high to be practical. Contents of the invention

[0003] The object of the present invention is to provide a synchronous grinding device for the inner and outer surfaces of the steel pipe end, which can ensure the grinding quality of the steel pipe end, improve the grindi...
