It should be understood that the specific embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the present utility model.
The polishing position adjustment device and the weld joint online polishing apparatus according to the present utility model are described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the present utility model provides a polishing position adjustment apparatus including a first temperature monitor 3, a second temperature monitor 4, and a rotating assembly 5. The first temperature monitoring piece 3 is used for measuring the temperature of a welding seam at the welding seam of the steel pipe 1;
the second temperature monitoring piece 4 is used for measuring the wall temperature of the outer peripheral wall of the steel pipe 1, and measuring points of the second temperature monitoring piece 4 are arranged close to two sides of the welding seam along the circumferential direction; the rotating assembly 5 is connected with the polishing device 2, and drives the polishing device 2 to move along with the welding seam according to the temperature difference between the welding seam temperature and the pipe wall temperature and perform polishing operation.
Specifically, the stainless steel pipe 1 is produced in a production line, in the prior art, the stainless steel pipe 1 is required to be taken off line for a weld polishing process after welding, and the polishing device 2 is required to be manually moved according to the weld shift for polishing. In the embodiment of the utility model, the first temperature monitoring piece 3, the second temperature monitoring piece 4 and the rotating assembly 5 all belong to the component parts of the production line of the steel pipe 1, so that the weld treatment of the steel pipe 1 is carried out on the production line without carrying out on-line and off-line operations, thereby saving the production time of the steel pipe 1; and, calculate the temperature difference through the welding seam temperature that first temperature monitoring piece 3 measured and the pipe wall temperature that second temperature monitoring piece 4 measured to use rotating assembly 5 to adjust steel pipe 1 welding seam position according to the temperature difference, thereby accomplish the tracking of burnishing device 2 to the welding seam, and then improve burnishing device 2's polishing rate.
The specific adjustment process of the polishing device 2 is as follows: firstly, the temperature of the welding line is measured through the first temperature monitoring piece 3, meanwhile, the temperature of the pipe wall of the welding line on two sides in the circumferential direction is measured through the second temperature monitoring piece 4, in fact, the temperature of the welding line is higher than the temperature of the pipe wall, then, the temperature difference between the temperature of the pipe wall on one side of the welding line and the temperature of the pipe wall on the other side of the welding line are calculated respectively, the two temperature differences are compared to judge the deviation direction of the welding line, namely, the welding line is deviated to the side when the temperature difference on the other side is large, finally, the polishing device 2 is driven to move along the welding line according to the deviation direction of the welding line through the rotating component 5 and polishing operation is carried out, and the automatic deviation of the polishing device 2 is realized instead of manual movement in the whole process, so that the polishing speed of the polishing device 2 is improved, and the production speed of the steel pipe 1 is further improved.
In the embodiment of the utility model, the central axis of the first temperature monitoring piece 3 is intersected with the straight line where the welding line is located, and the measuring directions of the first temperature monitoring piece 3 and the second temperature monitoring piece 4 are perpendicular to the peripheral wall of the steel pipe 1.
Specifically, the central axis of the first temperature monitoring piece 3 in the horizontal plane intersects with the projection of the welding seam in the horizontal plane, and coincides with the straight line where the diameter corresponding to the welding seam is located, that is, the first temperature monitoring piece 3 is perpendicular to the straight line where the welding seam is located, so that the first temperature monitoring piece 3 is closest to the welding seam, and the welding seam temperature measured by the first temperature monitoring piece 3 is more accurate, so that the tracking accuracy of the polishing device 2 is improved.
In the embodiment of the present utility model, the number of the second temperature monitoring pieces 4 is two and is arranged symmetrically at both sides of the first temperature monitoring piece 3.
Specifically, the distances between the two second temperature monitoring pieces 4 which are symmetrically arranged and the first temperature monitoring piece 3 are the same, that is, the two second temperature monitoring pieces 4 respectively measure the tube wall temperatures at the symmetrical positions of the two sides of the welding line, so that the distance variable is controlled, the deviation of the welding line, which is insufficient in measured temperature difference due to different distances, is avoided, the accuracy of tube wall temperature measurement is improved, and the accuracy of tracking by the polishing device 2 is improved.
Further, the included angle of the central axes of the two second temperature monitoring pieces 4 is 20-60 degrees. In fact, when the included angle between the central axes of the two second temperature monitoring pieces 4 is too large, the distance from the welding line to the measuring point of the second temperature monitoring pieces 4 increases, so that the temperature loss from the welding line to the measuring point is increased under the influence of the outside, and the measured temperature difference is insufficient to reflect the deviation of the welding line; when the included angle between the central axes of the two second temperature monitoring pieces 4 is too small, the second temperature monitoring pieces 4 and the first temperature monitoring pieces 3 may interfere, so that measurement cannot be completed. In the actual installation process of the first temperature monitoring piece 3 and the second temperature monitoring piece 4, the numerical value of the included angle between the two second temperature monitoring pieces 4 is determined according to the type of the selected temperature monitoring piece.
In the embodiment of the present utility model, the first temperature monitor 3 and the second temperature monitor 4 are both infrared temperature sensors. The infrared temperature sensor has the characteristics of high precision and high sensitivity, so that the accuracy of the measurement of the weld joint temperature and the pipe wall temperature is improved, and the tracking accuracy of the polishing device 2 is further improved.

Specifically, the horizontal planes of the first temperature monitoring piece 3 and the second temperature monitoring piece 4 are parallel to the horizontal plane of the cross section of the rotary sleeve 53, that is, the first temperature monitoring piece 3 and the second temperature monitoring piece 4 are spaced from the rotary sleeve 53 along the length of the steel pipe 1. During the polishing operation, the steel pipe 1 moves along the length direction, during the movement of the steel pipe 1, the first temperature monitoring piece 3 and the second temperature monitoring piece 4 perform measurement work, meanwhile, the measured temperature difference between the temperature of the welding seam and the temperature of the pipe wall is converted into an electric signal to be transmitted to the control unit 51, then the control unit 51 sends a rotation signal in a corresponding direction to the driving piece 52 according to the electric signal, and finally, the driving piece 52 drives the rotation sleeve 53 to drive the polishing device 2 to rotate in a corresponding direction according to the rotation signal so as to finish the welding seam tracking. The time interval between the whole temperature measurement and the rotation of the rotating sleeve 53 is short, and when the steel pipe 1 moves from the horizontal plane where the first temperature monitoring member 3 and the second temperature monitoring member 4 are located to the horizontal plane where the polishing device 2 is located, the control unit 51 has completed the signal conversion, and the driving member 52 drives the polishing device 2 to track the weld.
