Description

Technical Field

[0001] This utility model relates to the field of pipe welding technology, and specifically to a pipe welding device. Background Technology

[0002] The water hoses of a car engine are an important part of the cooling system. Their main function is to help the engine dissipate heat by delivering coolant, thereby maintaining the engine's operation within a suitable temperature range. In the cooling system, the design and connection method of the water hoses are crucial. For example, the water hoses need to be connected to other components (such as water pumps, radiators, etc.) through welding or other methods to ensure that the coolant can flow smoothly and dissipate heat effectively. The choice and operation of the welding process directly affect the sealing and durability of the water hoses.

[0003] Chinese utility model patent with authorization announcement number CN212145016U discloses an automated steel pipe welding equipment, including a main body of the equipment. The top and bottom of the main body of the equipment are respectively provided with welding equipment and welding stations for installing pipe fittings. The main body of the equipment is provided with a first rotating device and a second rotating device on both sides of the welding station. The first rotating device and the second rotating device respectively install two pipe fittings to be welded and align the pipe fittings on both sides at the welding station. At this time, the welding equipment is facing the weld. During welding, the rotation of both sides drives the pipe fittings to rotate at the same speed and in the same direction, thereby completing the welding.

[0004] In existing technologies, although the rotating devices on both sides drive the pipe to rotate during welding, the welding equipment is directly facing the weld. Prolonged welding will produce pores at the weld, leading to voids or cracks inside the weld, ultimately reducing the strength and toughness of the weld. In addition, existing technologies can only be used for welding one type of pipe, and are not applicable to all complex, irregularly shaped engine water pipes. Based on the above technical problems, the following improvements are proposed. Utility Model Content

[0005] The present invention aims to provide a pipe welding device to solve the problems of limited selectivity in welding pipes and poor welding strength.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pipe welding device, comprising a first guide platform and a second guide platform arranged perpendicularly to each other, wherein a mounting seat for installing pipe fittings and a welding mechanism for welding pipe fittings are slidably arranged on the first guide platform and the second guide platform, respectively, and the mounting seat includes a mounting plate slidably arranged on the first guide platform and a mounting part detachably connected to the mounting plate, wherein the mounting part is used to install pipe fittings on the mounting plate.

[0007] The beneficial effects of this solution are as follows: by setting up a first guide platform and a second guide platform that are perpendicular to each other, the pipe fittings to be welded are fixed to the mounting base through the mounting base and spliced ​​at the welding point. During welding, the second guide platform drives the welding mechanism to move back and forth at the weld seam to heat it, which can effectively avoid the problem of excessive local temperature at the weld seam, thereby improving the welding quality. In addition, through several detachable mounting parts, different mounting parts can be selected and installed for different pipe fittings, which can improve the selectivity of pipe fitting welding.

[0008] Furthermore, the installation section includes several mounting posts detachably connected to the mounting plate and a fixing component detachably connected to the mounting plate. The top of the mounting post is provided with a mounting groove for embedding the pipe fitting. The fixing component is used to fix the pipe fitting, and the mounting post is used to assist in positioning the pipe fitting.

[0009] Furthermore, the fixing assembly includes a quick clamp and a fixing block that are detachably connected to the mounting plate. The fixing block is detachably connected to a fixing member for fixing the pipe fitting. The quick clamp is used to fix the fixing member to the fixing block. The top of the fixing member is provided with a semi-circular fixing plate for the pipe fitting to be inserted. Both the fixing member and the fixing block are provided with corresponding connecting holes. The clamping end of the quick clamp is provided with a connector for passing through the connecting hole.

[0010] The beneficial effects of this solution are as follows: by setting up a fixing component, the pipe fitting needs to be positioned when it is initially installed on the mounting plate. Therefore, the pipe fitting is embedded in the fixing component by using quick clamps and fixing blocks, and then the various parts of the pipe fitting are positioned on the mounting plate by the mounting column. This achieves the purpose of fixing the pipe fitting to the mounting base and the mounting column assisting in positioning.

[0011] Furthermore, the connector includes a connecting post and an extrusion post arranged coaxially and in a cylindrical shape. The diameter of the cross-sectional circle of the connecting post is smaller than that of the cross-sectional circle of the extrusion post. The connecting post is used for interference fit with the connecting hole.

[0012] Furthermore, the fixing assembly also includes a support assembly detachably connected to the mounting plate. The support assembly includes a support block detachably connected to the mounting plate and a support rod vertically slidably connected to the top of the support block. An elastic element is provided between the support rod and the support block, and the elastic element is used to push the top of the support rod against the bottom of the circular fixing plate.

[0013] The beneficial effects of this solution are as follows: by setting up a support component, the elastic element pushes the end of the support rod against the bottom of the fixed plate, which can reduce the force on the fixed element and prevent the fixed element from bending and deforming.

[0014] Furthermore, the elastic element is set as a spring.

[0015] Furthermore, the mounting base also includes a slider that is detachably connected to the bottom of the mounting plate. The first guide platform has grooves on the left and right sides for the slider to be embedded in. There are several sliders, all of which are detachably connected to the grooves. The inclination of the top surface of the sliders to the horizontal plane is different.

[0016] The beneficial effects of this solution are as follows: by setting the top of several sliders with different inclinations, the mounting plate is installed at different inclination angles when it is mounted on the top of the sliders. Since the shape of the engine water pipes is unique, and the welding angle required for welding pipes at different drilling locations is also different, sliders with different inclinations can meet the needs of different angles, further increasing the selectivity of the mounting base and improving the function of the welding device.

[0017] Furthermore, a sliding frame is slidably connected to the second guide platform, and a welding mechanism is fixedly installed on the side of the mounting base near the second guide platform. A driving component is provided at the end of the second guide platform, which is used to drive the sliding frame to slide back and forth.

[0018] Furthermore, the welding mechanism includes spray guns symmetrically installed on both sides of the sliding frame and an air pipe connected to the sliding frame, with the air pipe connected to the spray guns.

[0019] Furthermore, the driving component is set as a cylinder. Attached Figure Description

[0026] Example

[0027] like Figures 1-2 The pipe welding device shown includes a frame, on which a first guide platform 1 and a second guide platform 2 are fixedly welded on the same horizontal plane. The first guide platform 1 and the second guide platform 2 are perpendicular to each other. The first guide platform 1 is arranged in a horizontally elongated block shape. The first guide platform 1 has a sliding groove 11 extending upwards to both sides. The sliding groove 11 extends through both sides. The first guide platform 1 is slidably connected to a slider 33 through the sliding groove 11. The slider 33 is detachably slidably connected to the first guide platform 1 through the openings on both sides of the sliding groove 11. The number of sliders 33 detachably connected to the first guide platform 1 is several, and there are several sliding grooves 11. The inclination angles between the top surface and the horizontal plane are all different. The top surface of the slider 33 is detachably connected to a mounting platform by bolts. The mounting platform includes a mounting plate 31 bolted to the slider 33. The mounting platform also includes a mounting part 32 detachably connected to the top of the mounting plate 31. The mounting part 32 includes a plurality of mounting posts 321 detachably connected to the surface of the mounting plate 31. The bottom ends of the plurality of mounting posts 321 are provided with mounting rods. The bottom end of the mounting plate 31 is provided with a plurality of holes for mounting rods to be inserted. The lengths of the plurality of mounting posts 321 are not all the same, and the top ends of the mounting posts 321 are provided with mounting grooves for pipe fittings to be inserted.

[0028] like Figures 2-4 As shown, the detachable mounting part 32 on the mounting plate 31 also includes a fixing component 4 detachably connected to the mounting plate 31. The fixing component 4 is used to fix the pipe fitting. The fixing component 4 includes a quick clamp 41 and a fixing block 42 detachably connected to the surface of the mounting plate 31. A base plate is fixedly welded to the bottom end of the quick clamp 41. The base plate is detachably connected to the mounting plate 31 by bolts. The bottom end of the fixing block 42 also has a protruding mounting rod. The detachable connection of the fixing block 42 is achieved by embedding the mounting rod into the reserved hole on the mounting plate 31. The fixing block 42 and the quick clamp 41 are mounted opposite each other on the mounting plate 31, and the side of the fixing block 42 closest to the quick clamp 41 is fixed by the quick clamp 41. The clamping end is detachably connected to a fixing member 421. Both the fixing member 421 and the fixing block 42 are provided with corresponding connecting holes 422. The clamping rod end of the quick clamp 41 is fixedly welded to a connector 411. The connector 411 includes a coaxially arranged cylindrical connecting post 4111 and a pressing post 4112. The connecting post 4111 is used to embed into and pass through the connecting hole 422 and has an interference fit with the connecting hole 422. The diameter of the cross-sectional circle of the pressing post 4112 is larger than the diameter of the cross-sectional circle of the connecting post 4111. Therefore, when the connecting post 4111 is embedded in the connecting hole 422, the side of the pressing post 4112 close to the connecting post 4111 abuts against the fixing block 42.

[0029] The top of the fastener 421 is integrally fixed with a semi-circular fixing plate 4211. The semi-circular recess of the fixing plate 4211 is used to embed the pipe fitting. Therefore, the fastener 421 is fixedly installed on the fixing block 42 by the quick clamp 41 of the fastening assembly 4. The fixing plate 4211 wraps and supports the outer wall of the pipe fitting, improving the connection stability during the installation and welding process of the pipe fitting. The fastening assembly 4 also includes a support assembly 43 detachably connected to the mounting plate 31. The support assembly 43 includes a support block 431 detachably connected to the mounting plate 31. The bottom end of the support block 431 also has a protruding mounting rod. A cavity is opened in the support block 431, and a support rod 432 is vertically slidably connected in the cavity. A spring 433 is connected between the support rod 432 and the bottom end of the cavity. The support block 431 is installed on the mounting plate 31 directly below the fastener 421. The spring 433 pushes the top end of the support rod 432 against the bottom end of the fixing plate 4211, thereby further supporting the pipe fitting.

[0030] like Figure 1 As shown, the second guide platform 2 is a long strip-shaped block arranged in the front and back direction on the frame. A sliding frame 22 is slidably connected to the second guide platform 2. A cylinder 23 is fixedly installed at the end of the second guide platform 2. The piston end of the cylinder 23 is fixedly connected to the sliding frame 22. A crossbar is fixedly welded to the sliding frame 22. Spray guns 211 are symmetrically installed at both ends of the crossbar. An air pipe 212 connected to the spray gun 211 is also installed on the sliding frame 22. The air pipe 212 is connected to an external air supply device and provides gas to the spray gun 211.

[0031] The specific implementation process is as follows: The pipe fittings to be welded are fixed on the mounting plate 31 by different mounting columns 321 and different fixing components 4, and the weld joints between the two pipe fittings to be welded are spliced. Different sliders 33 are selected according to different welding angles and the sliders 33 are connected to the mounting plate 31. During welding, the weld seam is placed between the two spray guns 211 and welded. The cylinder 23 drives the spray gun 211 to move back and forth through the sliding frame 22 to avoid local high temperature at the weld seam.
