Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, and more specifically to a high-precision welding machine. Background Technology

[0002] The main body of a helical pile is a rod with helical blades. These helical blades are usually continuous and evenly distributed along the length of the rod. The shape of the blades is somewhat like the threads of a screw, with a certain pitch and thickness. They are mainly used for treating soft soil foundations and for structural foundations requiring specific bearing capacity and stability. Before use, the helical blades need to be welded to the surface of the pile.

[0003] As shown in the prior art published in CN222370755U, although this prior art uses a rotating turntable to move a threaded rod upwards, causing the threaded rod to support the bottom of the pile, and then uses a lower pressure plate to limit the top of the pile, thus achieving positioning during pile rotation and preventing vibration, thereby improving the tightness of the weld connection. However, in this prior art, the welding fumes generated during welding spread and pollute the working environment, and the high-temperature heat generated is not utilized, resulting in resource waste. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a high-precision welding machine. A fan draws high-temperature fumes into a dust collection cylinder, and a filter ring filters the fumes into the dust collection cylinder. The high-temperature heat is then transported to the air supply hopper via a conveying pipe and a connecting pipe. The air supply hopper delivers the high-temperature hot air to the workpiece to be welded, blowing away any debris adhering to the welding position. At the same time, the high-temperature hot air can also preheat the welding position, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision welding machine, including a chassis, the top of which is provided with a processing part for welding workpieces;

[0006] The processed part is provided with functional components for dust absorption and heat utilization on its exterior;

[0007] The functional component includes a dust collection cylinder located on the top of the chassis, with an assembly plate installed on the top of the dust collection cylinder. A conveying pipe is fixedly connected to one side of the rear end of the dust collection cylinder, and a fan is installed inside the conveying pipe.

[0008] The end of the conveying pipe away from the dust collection cylinder is fixedly connected to a connecting pipe, and the bottom of the end of the connecting pipe away from the conveying pipe is fixedly connected to an air supply hopper.

[0009] In a preferred embodiment, the dust collection cylinder has a cover at its rear end, an installation ring is installed on the front side of the cover, the front end of the installation ring extends into the interior of the dust collection cylinder, and the exterior of the installation ring is threadedly connected to the inner wall of the dust collection cylinder. A filter ring is installed on the front side of the installation ring.

[0010] In a preferred embodiment, both the delivery pipe and the connecting pipe are filled with insulating cotton.

[0011] In a preferred embodiment, two spaced-apart support plates are installed at the top rear end of the chassis. The same support base is installed on the front side of the two support plates, and an electric slide rail is installed on the front side of the support base. The rear top of the assembly plate is fixed to the slide base on the electric slide rail.

[0012] In a preferred embodiment, the workpiece includes a fixed frame mounted on the front side of a slide block on an electric slide rail. A first electric push rod is mounted on the top of the fixed frame, and the bottom end of the first electric push rod passes through the fixed frame and extends to the bottom of the fixed frame.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Refer to the instruction manual appendix Figure 1-6 This utility model provides a high-precision welding machine, including a chassis 1. The top of the chassis 1 is provided with a processing component for welding workpieces. The processing component includes a fixing frame 15, which is installed on the front side of a slide block 16 on an electric slide rail 14. A first electric push rod 17 is installed on the top of the fixing frame 15, and the bottom end of the first electric push rod 17 passes through the fixing frame 15 and extends to the bottom of the fixing frame 15. A welding head 18 for welding workpieces is installed on the bottom end of the first electric push rod 17. Two spaced support plates 12 are installed on the top of the rear end of the chassis 1. The same support seat 13 is installed on the front side of the two support plates 12, and an electric slide rail 14 is installed on the front side of the support seat 13. The rear side of the top end of the assembly plate 3 is fixed together with the slide block 16 on the electric slide rail 14.

[0027] In use, the welding head 18 on the workpiece is moved laterally by the slide block 16 on the electric slide rail 14, thereby adjusting the welding position of the welding head 18 and improving the welding effect of the welding head 18 on the workpiece. Then, the welding head 18 is moved down by the first electric push rod 17, so that the welding head 18 contacts the workpiece for easy welding. At the same time, the connection between the assembly plate 3 and the slide block 16 on the electric slide rail 14 makes the position of the functional component and the workpiece consistent, so that the dust collection cylinder 2 can collect the fumes and dust during welding by the welding head 18.

[0028] like Figure 2 , 3 As shown in Figure 6, the processed part is provided with functional components for dust collection and heat utilization on its exterior; the functional components include a dust collection cylinder 2 located on the top of the housing 1, and an assembly plate 3 installed on the top of the dust collection cylinder 2. A conveying pipe 4 is fixedly connected to one side of the rear end of the dust collection cylinder 2, and a fan 5 is installed inside the conveying pipe 4; a connecting pipe 6 is fixedly connected to the end of the conveying pipe 4 away from the dust collection cylinder 2, and an air supply hopper 7 is fixedly connected to the bottom of the end of the connecting pipe 6 away from the conveying pipe 4. A cover 8 is provided at the rear end of the dust collection cylinder 2, and an installation ring 9 is installed on the front side of the cover 8. The front end of the installation ring 9 extends into the interior of the dust collection cylinder 2, and the exterior of the installation ring 9 is threadedly connected to the inner wall of the dust collection cylinder 2. A filter ring 10 is installed on the front side of the installation ring 9, and insulation cotton 11 is installed inside both the conveying pipe 4 and the connecting pipe 6.

[0029] During use, the high-temperature fumes generated during welding of the welding head 18 are drawn into the dust collection cylinder 2 by the fan 5, and then filtered into the dust collection cylinder 2 by the filter ring 10 to prevent the fumes from splashing and polluting the working environment. The high-temperature heat is transported to the air supply hopper 7 through the conveying pipe 4 and the connecting pipe 6, and the high-temperature hot air is transported to the position of the workpiece to be welded by the air supply hopper 7 to blow away the debris adhering to the position to be welded, so as to prevent the debris from adhering and affecting the welding effect. At the same time, the high-temperature hot air can also preheat the welding position to improve the subsequent welding efficiency. In this way, welding efficiency and welding effect can be improved while collecting fumes.

[0030] After welding is completed, the staff rotates the cover 8 to drive the mounting ring 9 which is threadedly connected to the dust collection cylinder 2. This allows the mounting ring 9 and the filter ring 10 to be removed from the dust collection cylinder 2, making it easier to clean and maintain the dust and filter ring 10 inside the dust collection cylinder 2.

[0031] At the same time, in order to facilitate omnidirectional welding of the workpiece, it is necessary to move and adjust the position of the workpiece, such as... Figure 1 As shown, two spaced support plates 12 are installed at the top rear end of the chassis 1. The same support base 13 is installed on the front side of the two support plates 12, and an electric slide rail 14 is installed on the front side of the support base 13. The rear top end of the assembly plate 3 is fixed together with the slide block 16 on the electric slide rail 14.

[0032] When welding workpieces, it is necessary to ensure the stability of the workpieces, such as Figure 1 , 4 As shown in Figure 5, a mounting base 19 and a positioning base 20 are installed on the top front end of the chassis 1. The mounting base 19 is located on the side of the positioning base 20 near the welding head 18. A three-jaw chuck 21 is installed on the side of the mounting base 19 near the positioning base 20 via a rotating shaft. A servo motor 22 is installed on the side of the mounting base 19 away from the three-jaw chuck 21. The output shaft of the servo motor 22 passes through the mounting base 19 and is fixed together with the rotating shaft on the three-jaw chuck 21. A support cylinder 23 is provided on the side of the positioning base 20 near the mounting base 19. A second electric push rod 24 for connecting the support cylinder 23 is installed on the side of the positioning base 20 away from the mounting base 19. The support cylinder 23 is movably connected to the second electric push rod 24 via a bearing.

[0033] In use, the operator places the workpiece between the mounting base 19 and the support base 13, and activates the three-jaw chuck 21 to clamp and fix one end of the workpiece. Then, the second electric push rod 24 pushes the support cylinder 23 to fit onto the other end of the workpiece. This achieves the effect of fixing and limiting the workpiece, ensuring the stability of the workpiece during welding. At the same time, the servo motor 22 drives the three-jaw chuck 21 to rotate, and the three-jaw chuck 21 then drives the clamped and fixed workpiece to rotate. This allows for all-round welding of the workpiece, improving the welding effect and welding efficiency.

[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
