Description

Technical Field

[0001] This utility model relates to the technical field of positioning equipment for flange welding, specifically to positioning equipment for welding flanges at the flue interface of a gas-fired wall-hung boiler. Background Technology

[0002] A gas-fired wall-hung boiler flue interface is a flue connection system that ensures the emission of exhaust gas and air circulation generated during combustion within the boiler. Most common gas-fired wall-hung boiler flues are connected via flanges. Before use, the flange needs to be welded to the pipe or equipment to form a permanent connection. Flange welding positioning equipment is usually used to assist in positioning the flange before welding to prevent the workpiece from shifting during the welding process.

[0003] Chinese utility model patent CN220971172U discloses an adjusting component and flange welding equipment, including "a rotating disk rotatably connected to one side of two adjacent moving plates via a rotating shaft; a positioning column fixedly connected to the center of the rotating disk on the side away from the moving plates; and an adjusting motor fixedly connected to one of the moving plates. This utility model, when fixing a flange to a pipe, ensures that the flange and pipe are always on the same central axis. During welding, it can automatically adjust the rotation of the flange and pipe without requiring the welder to change welding positions." However, fixing the flange and pipe by inflating and compressing an airbag can lead to some displacement and tilting during welding when the external force on the pipe and flange is too large, resulting in reduced welding accuracy and consequently reducing the applicability of the flange welding positioning equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for welding the flue gas interface flange of a gas wall-hung boiler, so as to solve the problem mentioned in the background art that when the flange and pipe are fixed by inflating and squeezing an airbag during the welding process, the pipe and flange will shift and tilt to a certain extent when the external force is too large, resulting in a reduction in the welding accuracy of the flange and pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for welding the flue interface flange of a gas wall-hung boiler, including an adjustment component, an installation plate installed inside the adjustment component, a locking component rotatably connected inside the installation plate, and a positioning component installed at one end of the locking component.

[0006] The locking assembly includes a locking base with an embedded compression groove inside. Two compression blocks are slidably connected inside the compression groove. A locking insert is fixedly connected to one end of each compression block, and a compression spring is fixedly connected to the other end of each compression block. A pressing block is fixedly connected to one side of each compression block, and a rotating rod is welded to the center of one side of the locking base.

[0007] The positioning component includes a positioning base, which is a hollow cylindrical structure. Four limiting grooves arranged in a cross pattern are evenly distributed through the outside of the positioning base. A limiting rod is fixedly connected inside the limiting groove. A positioning screw is rotatably connected to the center of the positioning base. A positioning block is threadedly connected to the outside of the positioning screw. Four rotating seats arranged in a cross pattern are fixedly connected to the outside of the positioning block. One end of a positioning rod is rotatably connected inside the rotating seat. A positioning groove is passed through the inside of the positioning rod. A positioning clamp is rotatably connected to the other end of the positioning rod.

[0008] The beneficial effects of this utility model are as follows: by setting screws in the positioning base on the mounting plate to drive four positioning rods to support and fix the flange and pipe from the inside, the positioning effect of the flange and pipe is improved. At the same time, by setting locking components to lock the screws, it is convenient to support and lock flanges and pipes of various predetermined specifications, improve the adaptability of flange welding positioning equipment, and thus improve the stability of flange and pipe welding.

[0009] To allow adjustment of the spacing between the two mounting plates:

[0010] The adjustment assembly is further configured such that: the adjustment component includes a welding base, and the welding base is a horizontally arranged L-shaped cross-section structure; the top of the welding base has a limit groove through it; the L-shaped sidewall of the welding base has an adjustment groove through it; a servo motor is installed at one end of the welding base; one end of the servo motor drives a bidirectional threaded shaft, and the bidirectional threaded shaft is rotatably connected to the inside of the adjustment groove; an adjustment block is fixedly connected to one side of the bottom of the mounting plate, and the adjustment block and the two ends of the bidirectional threaded shaft form a threaded connection structure, and the adjustment block is slidably connected to the inside of the adjustment groove.

[0011] By adopting the above technical solution, a servo motor is used to control the rotation of the bidirectional threaded shaft, which drives the mounting plate connected to the two adjusting blocks to slide, thereby adjusting the distance between the two mounting plates to adapt to the welding requirements of flanges and pipes of a certain specification, facilitating the positioning of flanges and pipes, and improving the adaptability of welding equipment.

[0012] To ensure stability during mounting plate adjustment:

[0013] The mounting plate is further configured such that: a limiting slider is installed at the bottom of the mounting plate, and there are two mounting plates and two limiting grooves. Both the limiting slider and the limiting groove are T-shaped cross-section structures, and the limiting slider is slidably connected to the inside of the limiting groove. The length of the limiting groove is the same as the length of the adjustment groove.

[0014] By adopting the above technical solution, the T-shaped cross-section limiting slider at the bottom of the mounting plate slides in the limiting groove in the welding base to ensure the stability of the mounting plate during movement, avoid the mounting plate tilting or shifting, improve the accuracy of welding flanges and pipes inside the mounting plate, and thus improve the performance of the welding equipment.

[0015] To achieve locking of the positioning screw in the positioning assembly:

[0016] The mounting plate is further configured such that a circular locking groove runs through its interior, and multiple locking slots with the same angle are uniformly embedded inside the locking groove. The locking base is rotatably connected to the interior of the locking groove, and the locking plug connects to the locking slots through the upper and lower ends of the locking base to form a plug-in connection structure.

[0017] By adopting the above technical solution, the compression block, together with the compression spring, drives the locking block to engage with the locking slot in the mounting plate to lock the predetermined rotation angle of the locking base, thereby locking the rotation of the positioning screw in the positioning assembly. This allows for adjustment of the support diameter of the positioning clamp controlled by the positioning screw, adapting to the needs of flanges and pipes of different diameters and improving the adaptability of the welding equipment.

[0018] To ensure the stability of the positioning clamp when fixing the flange and pipe:

[0019] Further configuration: one end of the positioning base is fixedly connected to one side of the mounting plate, and the positioning screw is fixedly connected to one end of the locking base; the outer walls on both sides of the positioning rod and the inner walls on both sides of the limiting groove form a sliding connection structure, and the limiting rod is slidably connected inside the positioning groove; the positioning clamp is a T-shaped cross-section structure, and the bottom of the T-shaped end of the positioning clamp and one end of the positioning rod form a rotating connection structure; and the top of the T-shaped end of the positioning clamp is set as an arc-shaped structure.

[0020] By adopting the above technical solution, the position of the positioning clamp is adjusted by the sliding of the four positioning rods linked on the positioning block driven by the positioning screw. At the same time, the position of the positioning rod is limited by the sliding of the positioning rod in the positioning groove within the positioning rod. This improves the stability of the positioning clamp on the positioning rod when it abuts against the flange and the inner wall of the pipe, thereby improving the fixing effect of the flange and the pipe, preventing the flange and the pipe from shifting during welding, and improving the stability of the welding equipment during use.

[0037] The computer software involved in the servo motor and other hardware carriers in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0038] Therefore, the "servo motor" and the like mentioned in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of the flange welding positioning device of this application, so as to solve the corresponding technical problems to be solved by this application.

[0039] The positioning device for welding the flue interface flange of this gas-fired wall-hung boiler operates as follows:

[0040] First, pass the inner wall of one end of the flange and pipe to be welded through the positioning bases 401 on the two mounting plates 2 in sequence, so that the inner wall of the flange and pipe fits against the outer wall of the positioning clamps 409 arranged in a cross shape on the positioning bases 401.

[0041] Then, press the two pressing blocks 306 at one end of the locking base 301 towards the center, causing the pressing blocks 303 connected to the pressing blocks 306 to slide towards each other in the pressing groove 302, pressing the pressing spring 305 in the center of the two pressing blocks 303, causing the locking inserts 304 at the other end of the two pressing blocks 303 to retract, until the locking inserts 304 disengage from the locking slots 204 in the locking groove 203. At the same time, rotate the rotating rod 307 connected to the locking base 301 at the other end of the mounting plate 2, causing the locking base 301 to rotate.

[0042] Next, when the locking base 301 rotates in the locking groove 203, it drives the positioning screw 404 connected to the other end to rotate in the positioning base 401. In conjunction with the positioning rod 407 rotatably connected to the rotating seat 406 with a cross distribution outside the positioning block 405, it slides in the limiting groove 402, driving the positioning block 405 threadedly connected to the positioning screw 404 to perform horizontal displacement. At the same time, under the limitation of the positioning groove 408 in the positioning rod 407 and the limiting rod 403 in the limiting groove 402, the positioning rod 407 extends evenly from the positioning base 401. In conjunction with the positioning clamp 409 rotating at the other end of the positioning rod 407, the spacing between the positioning clamps 409 with a cross distribution is adjusted to adapt to the diameter requirements of the flange and pipe of the predetermined specifications.

[0043] Finally, release the pressing block 306. Under the action of the compression spring 305, the locking blocks 304 on the two pressing blocks 303 are driven to engage with the locking slots 204 of the predetermined specifications and corresponding angles in the locking grooves 203, thus completing the locking. At the same time, the servo motor 104 (model: MS1-R) is started to drive the bidirectional threaded shaft 105 to rotate in the adjustment groove 103, which drives the adjustment blocks 202 with threads at both ends to slide in the adjustment groove 103. With the limit slider 201 at the bottom of the mounting plate 2 sliding in the limit slide groove 102, the two mounting plates 2 are driven to move closer to each other until the welding ends of the flange and the pipe are in contact with each other, thus completing the welding positioning and allowing subsequent welding operations to proceed.
