After the clamping assembly of the hydraulic electric push rod 101 finishes clamping and fixing the steel pipe, a user starts the first electric push rod 505 and the second electric push rod 603 through the control panel, then the control panel starts the hydraulic electric push rod 101 to drive the steel pipe to move leftwards, so that the steel pipe is in contact with the conical block of the baffle 506, after the inclined port of the steel pipe is in contact with the conical block of the baffle 506, the steel pipe is continuously pushed out along with the hydraulic electric push rod 101, the steel pipe rotates in the arc-shaped groove of the bearing support 1, so that the lowest part of the inclined port of the steel pipe is in contact with the conical block of the baffle 506, automatic adjustment of the angle of the inclined end of the steel pipe is completed, meanwhile, the steel pipe rotates to extrude the stop block of the second electric push rod 603 to move, and the stop block on the second electric push rod 603 moves to be the length of the inclined end of the steel pipe.

Because the rotation center of the L-shaped frame 103 is located in the middle of the second electric push rod 603 and the first electric push rod 505, and the length of the fixing plate 608 is half of the distance between the second electric push rod 603 and the first electric push rod 505, that is, when the horizontal distance of the movement of the front end of the fixing plate 608 is half of the horizontal distance of the movement of the stopper on the second electric push rod 603, the fixing plate 608 drives the L-shaped frame 103 and the fixing ring 105 to rotate, so that the fixing ring 105 is parallel to the inclined opening of the steel pipe.

The second electric push rod 603 drives the L-shaped sliding rod 601 and the connection connected therewith to move leftward together, and stretches the second tension spring 602, under the action of the fifth rack 607, the third sliding rod 604 moves to make the third spur gear 606 rotate, and the third spur gear 606 drives the second sliding frame 605 to move leftward, at this time, the moving distance of the second sliding frame 605 is half of the moving distance of the third sliding rod 604, the second sliding frame 605 moves to press the pressure sensor of the fixing plate 608, the pressure sensor transmits a signal to the control panel to start the servo motor 609 to rotate slowly, meanwhile, the rotation of the fixing plate 608 drives the rear portion of the second sliding frame 605 to expand and contract correspondingly through the n-shaped round rod, so that the second sliding frame 605 is always in contact with the pressure sensor of the fixing plate 608, after the third sliding rod 604 has moved, the value of the pressure sensor is zero, the control panel stops the servo motor 609 from working, and at this time, the servo motor has self-locking, thereby completing the self-adjustment of the swing angle 609 of the fixing ring 105, and facilitating the subsequent bevel operation on the steel pipe.

After the adjustment is finished, the user starts the first electric push rod 505 and the second electric push rod 603 through the control panel to reversely work and reset, that is, the conical block of the baffle 506 and the stop block of the second electric push rod 603 are released from the joint limit with the steel pipe, and the subsequent user repeats the above operations to correspondingly start the hydraulic electric push rod 101 and the first driving motor 104 to perform the groove operation on the steel pipe.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
