Problems solved by technology

The derusting device utilizes the air hole provided on the shaft head of the derusting drive shaft, which can promptly and effectively blow dust and other debris to the front, but the derusting device cannot be applied to derusting the inner wall of steel pipes with different diameters.
[0004] In the prior art, the device for polishing the outer wall of the steel pipe is also limited by the structure, and can only be used for polishing the outer wall of the steel pipe with a fixed diameter. For example, the patent with the publication number CN203738557U discloses a polishing device for the outer wall of the steel pipe. The composition includes a bracket, a platform is set on the bracket, a rotating cylinder is arranged on the platform, bearings are provided at both ends of the rotating cylinder through bearing seats, the bearing seats are fixed on the platform, steel brushes are arranged on the inner wall of the rotating cylinder, and the middle part of the rotating cylinder is There is an arc track, and a turntable is set under the arc track, and the turntable is connected to the rotating motor, and the turntable and the

Example Embodiment

[0025] Example one

[0026] Such as figure 1 As shown, a steel pipe inner and outer integrated automatic grinding system 1 includes an inner wall grinding device 10, a steel pipe fixing device 20, an outer wall grinding device 30, and a drive system. The steel pipe inner and outer integrated automatic grinding system 1 can synchronize the inner and outer walls of the steel pipe 9 Grinding and polishing. Such as figure 2 As shown, it is a schematic structural diagram of the inner wall grinding device 10 in an open state when it is working. The inner wall grinding device 10 includes an outer sleeve 101, an inner sleeve rod 102, and the inner sleeve rod 102 is inserted into the outer sleeve 101 and the two ends are respectively from the outer sleeve 101 The front end of the inner sleeve rod 102 is connected to the ends of a plurality of elastic branches 103, and the front end of each elastic branch 103 is provided with a grinding block 104.

Example Embodiment

[0033] Example two

[0034] A preferred embodiment of driving the inner wall grinding device 10 is provided. The steel pipe inner and outer integrated automatic grinding system further includes a fixed pillar 50, the fixed pillar 50 is provided with a fixing bolt 501, and the internal thread on the fixing bolt 501 is connected to the inner thread on the inner sleeve rod 102. External thread engagement. The inner wall grinding device driving motor 402 drives the entire inner wall grinding device 10 to rotate clockwise, and at the same time makes the inner wall grinding device 10 move at a uniform speed in the axial direction of the steel pipe relative to the fixed bolt 501, so as to realize the grinding of the entire inner wall of the steel pipe.

Example Embodiment

[0035] Example three

[0036] In the first embodiment, the front end of the outer sleeve 101 of the inner wall grinding device 10 is provided with a V-shaped opening 105 for restraining and controlling the opening angle of the plurality of elastic branches 103. Since the processing technology of the V-shaped opening 105 is relatively complicated, the wall thickness of the outer sleeve 101 is also required. In order to facilitate the production and popularization of the inner wall grinding device 10, alternatives such as Figure 8 As shown, a V-shaped sleeve 106 is inserted into the front end of the outer sleeve 101 and fixed, instead of the V-shaped opening 105 in the first embodiment. Only the ordinary outer sleeve is combined with the V-shaped sleeve 106.

Abstract

The invention relates to steel pipe precise machining equipment, in particular to an automatic steel pipe interior and exterior integrated grinding system. The synchronous grinding of the inner wall and the outer wall of a steel pipe is achieved, moreover, due to the rotating of the steel pipe, the circumferential speed difference of rotation of the steel pipe and rotation of a steel pipe outer wall grinding device and a steel pipe inner wall grinding device is increased, and the grinding efficiency is greatly improved. The automatic steel pipe interior and exterior integrated grinding systemcan be suitable for grinding of steel pipes with different pipe diameters, and it does not need to change a grinding head. Meanwhile, the automatic steel pipe interior and exterior integrated grindingsystem is simple in structure, low in cost and high in grinding efficiency and greatly meets the production requirements of steel pipe grinding.

Description

technical field [0001] The invention relates to a steel pipe finishing equipment, in particular to an automatic grinding system integrating the inside and outside of a spiral steel pipe. Background technique [0002] The application of steel pipes is very extensive, so the production volume is very large, and some steel pipes have a relatively large individual mass, so they must be stacked outdoors, but this will inevitably be exposed to the sun and rain, so the problem of rust has always plagued the steel pipes. Time and conditions apply. Moreover, in the production process of steel pipes, such as spiral steel pipes, the limitations of the production process require grinding and polishing. Manual grinding is not only inefficient, but also requires experienced workers to operate. Therefore, the market needs a grinding device with simple structure, low cost and high grinding efficiency. [0003] In the prior art, the size of the grinding wheel on the grinding machine for t...
