DETAILED DESCRIPTION

[0019] As Figure 1 AndFigure 3 As shown in the drawings, an auxiliary butt joint device for flange pipe welding processing includes a base 1, the upper end of the base 1 is rotationally connected with a clamping assembly 2, and the clamping assembly 2 includes a support frame 201, an annular frame 202, a guide rod 203, a first spring 204 and a clamping plate 205, the upper end of the support frame 201 is connected with the annular frame 202, the guide rod 203 penetrates through the inside of the annular frame 202, and the side of the annular frame 202 close to the central axis of the base 1 is connected with the first spring 204, and the side of the first spring 204 away from the annular frame 202 is connected with the clamping plate 205;

[0020] The elastic structure formed between the clamping plate 205, the first spring 204 and the annular frame 202 facilitates the annular frame 202 to continuously push the clamping plate 205, so as to facilitate the clamping plate 205 to stably clamp the flange pipe body 4, increase the tightness of the butt joint of the other flange pipe body 4, so as to facilitate the seamless welding of the two flange pipe bodies 4, and facilitate the welding of the connecting part of the flange pipe body 4 by the staff.

[0021] As shown in the drawings, Figure 1 , Figure 2 and Figure 4 , the lower end of the clamping assembly 2 close to the central axis of the base 1 is connected with a first air cylinder 3, and the upper end of the clamping assembly 2 close to the central axis of the base 1 is connected with a flange pipe body 4, the upper end of the base 1 is connected with a power assembly 5 on the left and right sides, and the side of the power assembly 5 close to the central axis of the base 1 is connected with a support positioning assembly 6.

[0022] As shown in the drawings, Figure 2 , the power assembly 5 includes a side frame 501, a second air cylinder 502 and a straight rod 503, and the side of the side frame 501 is installed with the second air cylinder 502, and the telescopic end of the second air cylinder 502 is connected with the straight rod 503;

[0023] The second air cylinder 502 is opened, the second air cylinder 502 is retracted, the straight rod 503 slides on the side frame 501, and the two support positioning assemblies 6 are close to each other.

[0024] As shown in the drawings, Figure 4 , the support positioning assembly 6 includes a push rod 601 and a second spring 602, and the side of the push rod 601 close to the horizontal center line of the flange pipe body 4 is connected with the second spring 602, the support positioning assembly 6 further includes a support plate 603 and a magnet 604, and the side of the push rod 601 close to the central axis of the base 1 is connected with the support plate 603, and the inside of the support plate 603 is inlaid with the magnet 604;

[0025] The push rod 601 is pushed by the movement of the straight rod 503, so that the push rod 601 pushes the support plate 603 outward, so that the support plate 603 supports the inside of the flange tube body 4. The support method of the support plate 603 can play a good centering role on the flange tube body 4, so that the horizontal center lines of the two parts of the flange tube body 4 are in the same straight line, which is convenient for the two flange tube bodies 4 to be connected.

[0026] Working principle: When using the auxiliary docking device for flange pipe welding, first manually dock the two flange pipe bodies 4 and place them on the top of the base 1, as shown in the figure. Figure 1 When the second cylinder 502 is in the position shown, the second cylinder 502 is opened and the second cylinder 502 is contracted, so that the straight rod 503 slides on the side frame 501, so that the two supporting positioning components 6 are close to each other, and the support plates 603 on both sides are adsorbed together through the magnet 604. Then, during the continuous pushing of the straight rod 503, the two support plates 603 are docked together through the magnet 604, so the two support plates 603 cannot move left and right when they are close to the inner middle of the flange tube body 4. The straight rod 503 continues to push and relies on the rotation structure between the push rod 601 and the support plate 603, as well as the rotation structure between the push rod 601 and the straight rod 503. Through the above two rotation structures, the straight rod 503 expands the four support plates 603 outward during the movement, so that the support plates 603 are against the inner wall of the flange tube body 4, and the two flange tube bodies 4 are centered, which is convenient for the two flange tube bodies 4 When the staff completes welding of the flange tube bodies 4, the clamping assembly 2 is released by the first cylinder 3, and then the supporting positioning assembly 6 is released by the second cylinder 502. The second spring 602 will pull the supporting plate 603, so that the supporting plate 603 loses its clamping inner clamping and centering effect, thereby facilitating the removal of the flange tube bodies 4.
