DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] To improve efficiency, Figure 1 As shown, a weld guide device according to the utility model comprises:

[0040] Machine base 15;

[0041] The upper roller part is arranged on the machine base 15;

[0042] The lower roller 14 is arranged on a machine base 15;

[0043] A guide portion, arranged on the upper roller portion;

[0044] The lifting part is arranged on the machine base 15 .

[0045] When in use, a set of weld guide mechanism with fast weld guide replacement is provided for the pipe welding unit through the machine base 15, the upper roller part, the lower roller 14, the guide part and the lifting part, which can effectively improve the efficiency of replacing the guide piece for pipeline welding.

[0046] For example, Figure 1 As shown, the utility model also includes that the lower roller 14 is located at the bottom of the upper roller part, and the upper roller part includes:

[0047] The main shaft 9 is connected with the lifting part;

[0048] A shaft sleeve 4 is arranged on the main shaft 9;

[0049] A positioning sleeve 3 is arranged on the shaft sleeve 4;

[0050] A bearing 7 is arranged on the shaft sleeve 4;

[0051] A locking nut 8 connected to the bearing 7 and the shaft sleeve 4;

[0052] The inner roller 5 is arranged on the bearing 7;

[0053] The outer roller 6 is arranged on a bearing 7 .

[0054] For guiding the weld, for example, Figure 1 As shown, the utility model also includes that the guide portion includes:

[0055] A guide plate 1 is arranged on the upper roller portion;

[0056] The tightening bolts 2 are connected with the inner roller 5, the guide plate 1 and the outer roller 6.

[0057] When in use, after the steel pipe blank enters between the lower roller 14 and the upper roller part, the guide piece 1 on the upper roller part guides the weld to be extruded into the steel pipe, so that the weld of the steel pipe blank can be stably guided to the welding end of the pipe welding machine.

[0058] For example, Figure 1 As shown, the utility model also includes that the lifting part includes:

[0059] The slide rail 12 is connected to the base 15;

[0060] The slider 13 is arranged on the slide rail 12 and connected to the main shaft 9;

[0061] The lock nut 11 is arranged on the base 15;

[0062] The upper roller lifting and lowering adjustment screw rod 10 is arranged on the lock nut 11 and connected to the slider 13.

[0063] When in use, by rotating the upper roller lifting and adjusting screw rod 10, the slider 13 drives the main shaft 9 to rise along with the upper roller lifting and adjusting screw rod 10, increasing the distance between the upper roller part and the lower roller 14, so as to help workers better operate the guide part on the upper roller part.

[0064] For example, Figure 1 As shown, the utility model also includes that the inner ring of the guide plate 1 is embedded between the inner roller 5 and the outer roller 6.

[0065] For example, Figure 1As shown, the utility model also includes that the bearings 7 are provided in two groups, the two groups of bearings 7 are respectively arranged at the center of the inner roller 5 and the outer roller 6, and the inner roller 5 and the outer roller 6 are respectively rotatably connected to the sleeve 4 through the corresponding bearings 7, and the positioning sleeve 3 is located between the two groups of bearings 7.

[0066] When in use, the minimum distance between the two groups of bearings 7 is positioned by the positioning sleeve 3 to prevent the inner roller 5 and the outer roller 6 from moving out of the working area.

[0067] For example, Figure 1 As shown, the utility model also includes that a hand wheel is arranged at the end of the main shaft 9.

[0068] When the utility model is in use, after the steel pipe blank enters between the lower roller 14 and the upper roller part, the guide piece 1 on the upper roller part guides the weld seam to be extruded to form the steel pipe, so that the weld seam of the steel pipe blank can be stably guided to the welding end of the pipe welding machine. When it is necessary to replace the guide piece 1, the upper roller lifting and adjusting screw rod 10 is rotated first, so that the slider 13 drives the main shaft 9 to rise along with the upper roller lifting and adjusting screw rod 10, and the spacing between the upper roller part and the lower roller 14 is increased to help workers better operate the guide part on the upper roller part, rotate the main shaft 9, remove the upper roller part, then remove the fastening bolt 2 by a screwdriver, unscrew the locking nut 8, remove the rolling roller and the guide piece 1, after replacing the guide piece 1, install the rolling roller, and then install the fastening bolt 2 and the locking nut 8 in turn, install the main shaft 9 back on the slider 13, and complete the replacement of the guide piece 1. The operation is simple and the overall operation safety is high.
