[0002] Metal fittings are various machine parts made of various metals. These fittings can be used as components of various machines and have multiple functions and uses. There are many types of metal fittings, including but not limited to furniture hardware fittings, cabinet hardware fittings, mold hardware fittings, door and window hardware fittings, etc. Metal pipe fittings are also a type of metal fittings. When processing metal pipe fittings, welding equipment is required to weld two sets of metal pipe fittings together.

[0003] Existing metal fitting welding equipment has poor positioning effect on metal pipes and cannot perform multi-directional positioning according to the size of the metal pipes. This causes the metal pipes to easily shift position during processing, which directly affects the processing accuracy of the metal pipes and thus directly increases the defect rate. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot perform multi-directional positioning of metal pipe fittings according to their dimensions, which leads to easy positional displacement of the metal pipe fittings during processing. Therefore, this invention proposes a metal fitting welding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A metal fitting welding device includes a welding table and a fixing ring located above the welding table. Placement racks are slidably mounted on both sides of the top of the welding table. Cylinders are fixed to both sides of the top of the welding table via vertical plates, and the piston rods of the cylinders are fixed to the placement racks.

A third electric slide rail is provided on the front side of the second electric slide rail through the second slide. A reinforcing vertical plate is fixed to the bottom of each set of the third electric slide rails through the third slide. The built-in screws of the first electric slide rails and the third electric slide rails are both positive and negative threaded rods.

[0008] Preferably, the telescopic positioning assembly includes a housing embedded in the front and back of the welding table. The front of the housing has a positioning groove, and a positioning plate is inserted into the housing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example

[0021] Reference Figure 1 and Figure 4A metal fitting welding device includes a welding table 1 and a fixing ring 9 located above the welding table 1. Placement racks 2 are slidably mounted on both sides of the top of the welding table 1. Two sets of sliding bars are symmetrically fixed to the bottom of each set of placement racks along the front-back direction. The welding table 1 has auxiliary slideways that cooperate with the sliding bars. The design of the sliding bars and auxiliary slideways can limit the sliding of the placement racks 2, effectively preventing them from shifting during movement. Cylinders 3 are fixed to both sides of the top of the welding table 1 via vertical plates, and the piston rods of the cylinders 3 are fixed to the placement racks 2. The welding table 1 is equipped with… The telescopic positioning assembly, used in conjunction with the fixing ring 9, has multiple sets of first electric push rods 10 evenly inserted on the right side of the surface of the fixing ring 9. The piston rods of the first electric push rods 10 are fixed with pressure plates. The telescopic positioning assembly includes a housing 4 embedded in the front and back of the welding table 1. A positioning groove is formed on the front of the housing 4, and a positioning plate 5 is inserted inside the housing 4. The top of the positioning plate 5 penetrates the housing 4 and is fixed with an mounting cylinder. The ends of the mounting cylinders, close to each other, are fixed to the front and back of the fixing ring 9. One set of first electric push rods 10 is inserted into one set of mounting cylinders. The positioning plate 5... A spring 7 is fixed at the bottom, and the bottom end of the spring 7 is fixed to the bottom of the inner cavity of the housing 4. A fixing screw 6 is fixed to the bottom of the front side of the positioning plate 5. The front side of the fixing screw 6 passes through the positioning groove and is threadedly connected to a positioning threaded sleeve 8. The back side of the positioning threaded sleeve 8 is attached to the housing 4. By setting a telescopic positioning component, the elastic rebound of the spring 7 can provide a certain amount of movement space for the positioning plate 5 and the mounting cylinder. In order to quickly fix the fixing ring 9 to one of the metal pipes according to the size of the metal pipes, with the cooperation of multiple sets of first electric push rods 10 and pressure plates, the fixing ring 9 can be quickly fixed to one of the metal pipes according to the size of the metal pipes. The threaded connection between the fixed screw 6 and the positioning threaded sleeve 8 allows for the rapid positioning of the moved positioning plate 5 using extrusion pressure, which in turn allows for the rapid positioning of the fixing ring 9. This facilitates the support and limitation of one set of metal pipe fittings, improving their stability. Furthermore, it allows the fixing ring 9 and the metal pipe fittings to be on the same transverse axis, enabling the rapid welding and fixing of the two sets of metal pipe fittings and improving welding stability. The number of first electric push rods 10 on the fixing ring 9 is at least three. Limiting the number of first electric push rods 10 improves the fixing effect between the fixing ring 9 and the metal pipe fittings.

[0022] Reference Figures 1-4Multiple sets of teeth 11 are evenly fixed on the left side of the surface of the fixing ring 9. An extension frame 12 is slidably arranged on one side of the front of the fixing ring 9. A second electric push rod 15 is embedded in the front of the extension frame 12. The piston rod of the second electric push rod 15 is fixed to a welding torch 16 through a docking plate. A motor 13 is fixed on the extension frame 12. The welding table 1 has a placement groove that cooperates with the first electric push rod 10, the second electric push rod 15, the welding torch 16, and the extension frame 12. The design of the placement groove avoids the first electric push rod 10, the second electric push rod 15, the welding torch 16, and the extension frame 12 from colliding with the welding table 1 when rotating. The output shaft of the motor 13 is fixed with a gear 14 that meshes with the teeth 11. The placement frame 2 is provided with a controllable positioning component for limiting the metal pipe. The controllable positioning component includes a first electric slide rail 17 fixed on both sides of the bottom of the inner cavity of the placement frame 2. Each set of first electric slide rail 17... A push plate 19 is rotatably mounted on the first slide. A pusher 18, which works with metal pipe fittings, is symmetrically mounted on both sides of the inner cavity of each set of placement racks 2 in the front-back direction. One end of the push plate 19 is rotatably mounted on the pusher 18. A second electric slide rail 20 is fixed to the back of the bottom of the inner cavity of each set of placement racks 2. A third electric slide rail 21 is mounted on the front of the second electric slide rail 20 via the second slide rail. A reinforcing vertical plate 22 is fixed to the bottom of each set of third electric slide rail 21 via the third slide rail. The built-in screws of the first electric slide rail 17 and the third electric slide rail 21 are both positive and negative threaded rods. By setting a controllable positioning component and adopting a multi-directional positioning method, the metal pipe fittings to be welded can be quickly positioned according to their dimensions, effectively preventing displacement of the metal pipe fittings during welding and improving the overall stability of the metal pipe fittings during welding. A controller is set on one side of the front of the welding table 1.

[0023] In this invention, the user activates the first electric slide rail 17 via a controller. The first electric slide rail 17, through its built-in positive and negative threaded rods, drives two adjacent sets of push plates 19 to move synchronously in opposite directions, thereby driving two adjacent sets of push frames 18 to swing synchronously in opposite directions until the push frames 18 are adjusted to a suitable angle according to the size of the metal pipe. The user then places the metal pipe to be welded on the push frames 18. At this time, multiple push frames 18 provide stable support for the bottom of the metal pipe. The user then activates the second electric slide rail 20 via the controller. The second electric slide rail 20 drives the third electric slide rail 21 downwards until the bottom of the third electric slide rail 21 contacts the top of the metal pipe, pressing down on its top. Simultaneously, the user uses the third electric slide rail 21, along with its built-in positive and negative threaded rods, to drive two sets of reinforcing vertical plates 22 to move synchronously inwards, clamping and positioning the front and back of the metal pipe. This multi-directional positioning method allows for rapid positioning of the metal pipe to be welded according to its required dimensions. The user then controls the position of the placement rack 2 via cylinder 3 to connect the two fixed metal pipes and move the connection point of the metal pipes to the same longitudinal plane as the welding torch 16. At this time, one set of metal pipes is located inside the fixing ring 9, and the elastic rebound of the spring 7 provides a certain support force and movement space to the positioning plate 5. The user then controls the position of the pressure plate via the first electric push rod 10, so that multiple pressure plates can quickly fix the fixing ring 9 onto one set of metal pipes according to the size of the metal pipes. At this time, the fixing ring 9 and the metal pipes are on the same transverse axis. The user then rotates the positioning threaded sleeve 8, and the fixing screw 6 and the positioning threaded sleeve 8 are threaded together to quickly position the moved positioning plate 5 using the extrusion force, thereby quickly positioning the fixing ring 9. The user then uses the second electric push rod 15 to adjust the position between the welding torch 16 and the metal pipes, and drives the gear 14 to rotate via motor 13. The meshing of the gear 14 and the teeth 11 drives the welding torch 16 to rotate, thus performing full welding on the connection point of the metal pipes.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
