[0002] The pipe welding tool is a fixture used to fix, press, and position the various components of the pipe during the pipe welding process. In the welding of connecting pipes used in semiconductors, since the connecting pipes are mainly composed of flanges and pipe bodies, the product size requirements are relatively high. Not only is it necessary to locate the relative position between the flange and the pipe body, but it is also necessary to locate the relative position between the two flanges. The existing tooling requires multiple dimensional measurements when assembling and positioning the pipe fittings, and multiple fine-tuning of the assembly position of the pipe fittings to ensure the dimensional accuracy of the pipe assembly. Repeated operations cannot complete the assembly and positioning of the various components of the pipe fittings at one time. At the same time, some tooling is highly targeted, and it is difficult to make adaptive adjustments for pipe fittings of different specifications.

[0012] In a preferred embodiment of the utility model, a rounded corner is arranged on an edge of one side of the limiting support block facing the tube body.

[0013] The beneficial effects of the utility model are: the assembly structure between the vertical pole, the top seat and the base is detachable, the flange can be fixed on the top seat and the base by bolts, the pipe body can be positioned on the top seat or the base by the limit support block and the air pipe pressing piece, and finally the pipe body and the flange are fixedly connected into a whole by connecting the vertical pole with the top seat and the base, which ensures the assembly accuracy and is also convenient for welding.

[0019] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] It should be noted that if there are directional indications (such as up, down, bottom, top, etc.) involved in this embodiment, the directional indication is only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0021] like Figure 1-Figure 3 As shown, a semiconductor equipment precision pipe welding device includes a vertical pole 1, and a top seat 2 and a base 3 detachably connected to both ends of the vertical pole 1;

[0022] A plurality of positioning screw holes 4 are provided on the top seat 2 and the base 3, and the plurality of positioning screw holes 4 correspond to the hole positions on the flange;

[0023] A pressing piece fixing block 5 and a plurality of limiting support blocks 6 that can abut against the pipe body and the inner wall of the flange are movably inserted on the top seat 2 and / or the base 3 , and a trachea pressing piece 7 is movably embedded on the pressing piece fixing block 5 .

[0024] Specifically, the detachable assembly structure between the vertical pole 1, the top seat 2, and the base 3, in conjunction with the positioning screw holes 4 on the top seat 2 and the base 3, can fix the flange on the top seat 2 or the base 3 by bolts to locate and fix the position of the flange. The pipe body and the top seat 2 or the base 3 can also be supported on the inner wall of the pipe body by the limiting support block 6 and the trachea pressing piece 7 to complete the positioning, and determine the splicing positioning between the pipe body and the flange. At the same time, the limiting support block 6 and the trachea pressing piece 7 can also support the pipe body during welding, which can effectively prevent the pipe body from deforming during welding. Finally, by connecting the vertical pole 1 with the top seat 2 and the base 3, the pipe body is clamped and fixed between the top seat 2 and the base 3, and the splicing positioning and fixation between the flanges and the flanges and between the flanges and the pipe body are determined. The tooling has a simple structure and a low manufacturing cost. While having high positioning accuracy, it can also correspond to connecting pipes of corresponding specifications by replacing limit support blocks 6, air pipe pressure plates 7, and vertical poles 1 of different specifications, and opening positioning screw holes 4 at different positions on the top seat 2 and the base 3. It adopts a detachable structure with better versatility.

The tenon heads 8 on the vertical pole 1, the limit support block 6 and the pressing plate fixing block 5 and the mortises 9 on the top seat 2 and the base 3 form a mortise and tenon structure, so that the vertical pole 1, the limit support block 6, the pressing plate fixing block 5, the top seat 2 and the base 3 can be quickly assembled together, and due to the particularity of the mortise and tenon connection, when the components are assembled, the assembly accuracy can also be guaranteed, thereby improving the dimensional accuracy of the flange plate and the pipe body.

[0026] Furthermore, in order to enhance the strength of the connection between the top seat 2, the base 3 and the upright 1, as Figure 1-Figure 3 As shown, a first bolt 10 capable of being screwed to the upright pole 1 is provided on the top seat 2 and / or the base 3 .

[0027] Furthermore, in order to prevent the limiting support block 6 from slipping off the base 3 or the top seat 2, as shown in FIG. Figure 1 , Figure 2 As shown, a right-angle notch 601 is formed on the limiting support block 6 , and a second bolt 11 which can be pressed on one side of the right-angle notch 601 is threadedly connected to the top seat 2 and / or the base 3 .

[0028] In this embodiment, the sheet fixing block 5 is a combination of multiple structures to facilitate adjustment according to different needs. Specifically, the sheet fixing block 5 includes a connection block 501 that can be mortised with the mortise 9, a limiting column 502 that can be plugged with the tracheal sheet 7, and the limiting column 502 can be movably plugged into the connection block 501.

[0029] Furthermore, in order to facilitate the support of the limiting support block 6 on the inner wall of the tube body, a rounded corner is provided on one edge of the limiting support block 6 facing the tube body, so as to guide and correct the installation of the tube body on the top seat 2 or the base 3 .

[0030] Working principle: The vertical pole 1, the top seat 2 and the base 3 are a detachable assembly structure. The flange can be fixed on the top seat 2 and the base 3 by bolts. The pipe body can be positioned on the top seat 2 or the base 3 by the limiting support block 6 and the air pipe pressing piece 7. Finally, the pipe body and the flange are fixedly connected into a whole by connecting the vertical pole 1 with the top seat 2 and the base 3 to facilitate welding.

[0031] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model.
