Example Embodiment

[0039] Example 1:

[0040] See Figure 1-9 As shown, the centrifugal equipment used for inner surface treatment of pipes includes:

[0041] The base 10 has a through hole for placing the pipe 60 on the base 10,

[0042] The manipulator 20 is installed on the base 10, and the manipulator 20 is used to clamp the polishing assembly 30 and drive the polishing assembly 30 to rotate to polish the inner wall of the pipe 60,

[0043] Wherein, the gap between the pipe 60 and the through hole on the base 10 is filled with a fastener 40. The fastener 40 includes a first ring 41 sleeved on the outer wall of the pipe 60, and the first ring 41 is connected with a coaxial second Ring body 42, the upper and lower ends of the second ring body 42 have unequal diameters. The smaller diameter end is connected to the first ring body 40 and has the same diameter. The second ring body 42 is divided into several sections by the notch 43. The first ring body 41 has A notch 43 corresponds to a notch 43 on th...

[0059] Example 2:

[0060] The base 10 in the centrifugal equipment used for the inner surface treatment of pipes of the present invention can be a frame or other bases for supporting and assembling components, and should not be limited to its structural shape. The diameter of the through hole on the base 10 is larger than that of the processed pipe 60. The outer diameter and the specific size are selected according to the actual processing conditions. The manipulator 20 referred to in the present invention is a manipulator with clamping and driving shaft-like workpieces to rotate. This is a common technical method in the prior art and should be understood by those skilled in the art The material of the polishing sleeve 34 and the polishing strip 33 in the present invention should be reasonably selected according to the material of the pipe 60 to be polished. For example, when the pipe 60 made of 45 steel is processed and the polishing sleeve 34 and the polishing strip are made of...

[0061] Example 3:

[0062] When the centrifugal equipment for inner surface treatment of pipes of the present invention is actually used: after the fastener 40 is sleeved on the outer surface of the pipe 60, the pipe 60 is pressed into the through hole on the base body 10, and it can be used in the pressing process The rubber hammer beats the pipe 60 to facilitate entry into the through hole in the base 10, and then tightens the nut on the outside of the clamping block 70. During the tightening of the nut, the gap between the clamping block 70 and the pipe 60 is reduced. To realize the clamping of the pipe 60, after completing the positioning and clamping of the pipe 60, the manipulator 20 clamps the grinding assembly 30 and drives the grinding assembly 30 to rotate to polish the inner wall of the pipe 60. After the grinding process is completed, the brush assembly 50 The inner wall of the pipe is oiled or painted.

Abstract

The invention discloses a centrifugal device for treating the inner surface of a pipe, and belongs to the technical field of pipe processing. The device comprises a base body and a mechanical arm; thebase body is provided with a through hole for placing the pipe; the mechanical arm is mounted on the base body and is used for clamping a polishing assembly and driving the polishing assembly to rotate to polish the inner wall of the pipe, and a gap between the pipe and the through hole in the base body is filled with a fastening piece; and the fastening piece comprises a first ring body connected to the outer wall of the pipe in a sleeving manner, the first ring body is connected with a coaxial second ring body, the upper and lower ends of the second ring body are unequal in diameter, the end with the smaller diameter is connected to the first ring body and is equal to the first ring body in diameter, the second ring body is divided into a plurality of segments from a notch, and a notchin the first ring body corresponds to the notch in the second ring body. According to the centrifugal device, in the process of treating the inner surface of the pipe, the vibration of the pipe is effectively reduced, the rate of adhesion between cleaning debris on the inner surface of the pipe and the inner wall of the pipe is low, and the quality of the inner surface of the processed pipe is high.

Description

technical field [0001] The invention belongs to the technical field of pipe processing, and in particular relates to a centrifugal device for treating the inner surface of pipes. Background technique [0002] In modern steel pipe production, more and more heat treatment is used to improve its strength, toughness or other specific performance. However, due to the high cost of the protective atmosphere heat treatment furnace, it is rare. However, due to the poor sealing of the furnace body and input and output devices in the current common steel pipe heat treatment furnace, the inner and outer surfaces of the pipe will be oxidized at high temperature during heat treatment, thereby forming dense oxide scales, which will affect the appearance and performance of the product. In order to obtain a smooth surface, there is usually a process of removing iron oxide scales on the inner and outer surfaces after heat treatment. The common ways to remove the iron oxide scale on the inne...
