Detailed Description
The present invention will be further described below with reference to specific embodiments, but the present invention is not limited to the following specific embodiments.
A positioning mechanism for a laser pipe welding machine is mainly used for receiving a pipe conveyed by a feeding mechanism and then positioning the pipe, and is convenient for welding of a pipe welding mechanism, and comprises a rack 1, wherein a through hole 13 is formed in the rack 1, the through hole 13 is mainly used for the pipe to pass through, and the through hole 13 is large, so that the positioning mechanism can be adjusted according to the size of the pipe, a first positioning device is arranged on one side of the through hole 13, a second positioning device is arranged on the other side of the through hole 13, and a welding seam guide device is arranged between the first positioning device and the second positioning device; wherein:
the first positioning device is arranged on one side of the rack 1 and used for receiving the pipe conveyed from the feeding mechanism, and mainly comprises a lower limiting device and a side limiting device, wherein the lower limiting device is a lower supporting piece 7 and can adjust the vertical height, the side limiting device is a left supporting piece 8 and a right supporting piece 9 and can adjust the horizontal position, and rollers are arranged on the left supporting piece 8 and the right supporting piece 9 of the lower supporting piece 7, so that the pipe can conveniently slide;
second positioner, including five roller positioning mechanism, mainly be snub pulley 2, left side compression roller 3, right side compression roller 4, compression roller 6 is gone up to first last compression roller 5 and second, snub pulley 2 is used for supporting the tubular product lower part, can carry out vertical regulation, left side compression roller 3 is used for supporting the tubular product left side, can carry out horizontal adjustment, right side compression roller 4 is used for supporting the tubular product right side, can carry out horizontal regulation, compression roller 6 sets up respectively in the 11 both sides of crack guide piece on first last compression roller 5 and the second, can carry out horizontal regulation and vertical regulation, can be 30-45 settings with vertical line, these roller regulation also mainly are driven through power unit, like cylinder or motor etc. And lower idler 2, left side compression roller 3, right side compression roller 4, compression roller 6 all can rotate on first upper compression roller 5 and the second, mainly drive through power unit, like the motor, can drive tubular product and move forward like this, and because the size of tubular product probably changes, so these five rollers of compression roller 6 all are detachable connection in frame 1 on lower idler 2, left side compression roller 3, right side compression roller 4, first upper compression roller 5 and the second.
A welding seam guiding device comprises a guide pipe 10 inserted into the pipe, wherein the insertion means passive insertion, that is, the pipe is moving, and the guide pipe 10 is stationary, when the pipe moves to the position of the guide pipe 10, the guide pipe 10 is automatically inserted into the pipe, the interior of the guide pipe 10 is hollow, and has two channels, one channel is communicated with cooling water for cooling the pipe, and is a circulating channel, so that the cooling water cannot leak out from the guide pipe 10 and only flows in the circulating channel, the other channel is communicated with welding protective gas, such as nitrogen, and is sprayed out from a gas outlet at the upper part of the front end of the guide pipe 10, because the welding seam is generally at that position, the welding effect is better, the upper part of the guide pipe 10 is provided with a seam guide sheet 11 for matching with the welding seam and guiding the position of the welding seam, and the seam guide sheet 11 is locked on the guide pipe 10 by a screw, and the thickness of the end of the seam guide piece 11 close to the welding position is smaller than that of the end far away from the welding position, so that the seam is narrower and narrower until the welding position is reached for welding, the seam guide device also comprises an upper clamping device 12 for clamping the seam guide piece 11, the upper clamping device 12 is arranged on one surface of the rack 1, and the main function is to clamp the seam guide piece 11 to play a role in fixing the guide pipe 10 and can be adjusted in the vertical direction.
The working principle of the positioning mechanism is as follows: tubular product moves along with feeding mechanism toward frame 1, when removing a certain position, the tubular product front end can stretch into in the space that forms between lower supporter 7 and the left and right sides support piece 9, and continue to move forward and can entangle guide tube 10, and the crack on the guide tube 1018 can pass the gap on the tubular product this moment, and then play the direction locate function, because lower supporter 7, left supporter 8 and right supporter 9 still are provided with the gyro wheel, and tubular product still is promoted by feeding mechanism this moment, tubular product can continue to move forward, then can contact with five rollers, then tubular product is cliied according to the size of tubular product to five rollers, can be better promptly fix a position the tubular product between five rollers, then rotate through five rollers and drive tubular product forward movement to welding position and weld.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
