Description

Technical Field

[0001] The utility model belongs to the technical field of pipe fitting welding, and particularly relates to a welding positioning device for the column of an air suction channel. Background Technique

[0002] Since the air suction channel mainly includes pipe fittings and sealing plates, at present, for the welding of the air suction channel, the sealing plate is mainly welded on the pipe fittings.

[0003] For the pipe fittings with a sheet metal sealing plate welded at the end, the conventional method is only to make stepped holes on the flange for positioning, with high processing costs. It can neither meet the angle of the pipe fittings nor position the folded sheet metal sealing plate, so that the shaping treatment is still required after welding, resulting in high part costs. Content of the Utility Model

[0004] In view of the above problems in the prior art, the purpose of the utility model is to provide a welding positioning device for the column of an air suction channel, which can complete the angle and size positioning of the sealing plate through simple adjustment and meet the expected accuracy requirements.

[0005] The utility model provides the following technical solutions:

[0006] A welding positioning device for the column of an air suction channel includes a bottom plate, support columns, pipe fitting support columns and columns arranged side by side on the bottom plate, a moving block movably installed on the support columns through a cylinder and a linear guide rail, a pipe fitting bracket installed on the pipe fitting support columns, a plurality of elbow clamps installed on the pipe fitting bracket, and a sealing plate positioning block installed on the column.

[0007] Specifically, a groove is provided on the sealing plate positioning block.

[0008] Specifically, a folding surface is provided on the moving block, and the folding surface fits with the sealing plate I.

[0009] Specifically, a plurality of positioning pins are further installed on the moving block.

[0010] The beneficial effects of the utility model are as follows:

[0011] This device first positions the pipe fittings and the sealing plate relative to each other, so it can meet the welding requirements for a certain angle at the pipe fitting sealing part, and at the same time can meet the welding requirements for a folded sealing plate with a certain angle; whether it is the pipe fitting angle or the folded sealing plate, this device can meet their positioning and welding requirements.

Specific embodiments

[0018] As Figure 1 shown, the air intake passage includes a pipe fitting 1, and a first sealing plate 2 and a second sealing plate 3 respectively welded to both ends of the pipe fitting 1.

[0019] As Figure 2 shown, the present utility model provides an air intake passage column welding positioning device, which includes a bottom plate 4, a support column 5, a pipe fitting support column 6 and a column 7 arranged in parallel on the bottom plate 4, a moving block 14 movably installed on the support column 5 through a cylinder 9 cooperating with a linear guide rail 8, a pipe fitting bracket 10 installed on the pipe fitting support column 6, a plurality of elbow clamps 13 installed on the pipe fitting bracket 10, and a sealing plate positioning block 11 installed on the column 7.

[0020] The second sealing plate 3 is placed inside the sealing plate positioning block 11, the pipe fitting 1 is placed on the pipe fitting bracket 10, and the pipe fitting 1 is fixed by the elbow clamps 13, and the first sealing plate 2 is placed on the moving block 14.

[0021] Specifically, please refer to Figure 3 for emphasis. The sealing plate positioning block 11 is provided with a groove 12, and the second sealing plate 3 is placed inside the groove 12. Please refer to Figure 4 for emphasis. The moving block 14 is provided with a folding surface 15, and the folding surface 15 fits with the first sealing plate 2, so as to facilitate positioning the first sealing plate 2 of the folded sheet metal with a certain angle; further, a plurality of positioning pins 16 are also installed on the moving block 14, so as to further fix the first sealing plate 2, and thus facilitate welding the folded sheet metal with an angle.

[0022] The working principle of the present utility model is:

[0023] First, the staff places the second sealing plate 3 into the second sealing plate positioning block 11, then presses the pipe fitting 1 against the second sealing plate 3, and at the same time positions the pipe fitting 1 through the toggle clamp 13. After that, the first sealing plate 2 is placed on the moving block 14, and the positioning pin 16 is rotated to position the first sealing plate 2. At the same time, the air cylinder 9 is activated, and the air cylinder 9 pushes the moving block 14 to make the first sealing plate 2 fit the pipe fitting 1. At this time, a fixed state is formed among the second sealing plate 3, the pipe fitting 1, and the first sealing plate 2, thus facilitating the staff to weld them.

[0024] This device first performs mutual positioning between the pipe fitting and the sealing plate. Therefore, it can meet the welding requirements for a certain angle at the sealed end of the pipe fitting, and at the same time can meet the welding requirements for a folded sealing plate with a certain angle. Whether it is the angle of the pipe fitting or the folded sealing plate, this device can meet their positioning and welding requirements.

[0025] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
