Description

TECHNICAL FIELD

[0001] The application relates to the technical field of inner container flange welding, in particular to a multi-station water heater inner container flange welding device. BACKGROUND

[0002] The water heater inner container is a core component of the water heater and is widely used in various household, commercial and industrial hot water supply systems. In the family scene, whether it is daily washing, bathing, or kitchen cleaning water, the hot water stored and heated by the inner container can meet people's diverse needs at any time. It can accurately adapt to different household types and water consumption. Small households can choose smaller capacity inner container type water heaters, which can be easily installed in limited space with their compact inner container design, providing the right amount of hot water for residents; large households or multi-person households rely on large capacity inner containers to ensure continuous hot water supply for multiple people. In commercial places such as hotels and guesthouses, stable and large-scale hot water supply is the key to improving customer satisfaction.

[0003] In the processing flow of the water heater inner container, the flange welding link is very important but also has many problems. At present, the flange welding in most production scenes still relies on manual operation. The efficiency of manual welding is extremely low. Welders need to carefully weld the flanges one by one. The operation process is tedious and time-consuming, and it is difficult to meet the urgent needs of large-scale production for speed. Some enterprises have introduced flow welding equipment. However, the equipment is not smooth during the transfer of the water heater inner container to the welding station. The inner container often stalls during transfer, and in severe cases, it may even stop completely. Once this happens, the subsequent welding process cannot be carried out on time and in order, which not only causes production to stop, but also greatly increases the risk of welding failure and produces defective products. SUMMARY

[0004] The device provides a multi-station water heater inner container flange welding device, and the specific implementation is as follows:

[0005] The multi-station water heater inner container flange welding device comprises:

[0006] A vertical frame and a plurality of welding assemblies arranged side by side, the welding assembly comprising a third air cylinder and a second lifting plate connected to the output of the third air cylinder, the second lifting plate being provided with a second motor, and the output of the second motor being provided with a welding head;

[0007] A horizontal frame and a jacking feeding assembly sliding along the length direction of the horizontal frame, the vertical frame and the horizontal frame each being provided with an open middle placement plate, the jacking feeding assembly being composed of a plurality of first air cylinders arranged at equal intervals, and each first air cylinder being provided with a jacking head vertically penetrating the middle part of the placement plate, the two inner container flanges being fed into the welding position of the welding assembly by the jacking feeding assembly, and the inner container flanges on the placement plate being welded by the welding assemblies to realize double-station synchronous welding.

[0008] Preferably, the third cylinder is vertically mounted above the vertical frame via a mounting plate, and a guide rail structure is provided between the mounting plate and the second lifting plate.

[0009] Based on the above technical solutions, a lifting and feeding assembly is introduced. This assembly is equipped with a three-row first cylinder and a lifting head. The dual-station welding layout allows two inner flanges to be welded simultaneously, which greatly saves time and significantly improves welding efficiency. After welding is completed, the lifting and feeding assembly delivers the welded inner flanges. This not only solves the problems of low efficiency and insufficient precision of traditional manual welding, but also overcomes the drawbacks of jamming during the transfer process of automated welding equipment.

[0010] Preferably, each first cylinder is integrated into one unit via a translation seat, and a pushing structure is provided between the translation seat and the horizontal frame.

[0011] Preferably, the placement plate includes a split plate body, the plate body is provided with positioning protrusions, and the positioning protrusions are provided with multiple arc-shaped limiting grooves in the radial direction.

[0012] Based on the above technical solutions, by setting multiple arc-shaped limiting grooves on the positioning protrusion, the positioning of the inner flange on the placement plate is achieved regardless of its specifications, diameter, or length, thus improving the accuracy of lifting, transporting, and reaching the welding position. The pushing structure is a guide rail structure driven by conventional air cylinders and hydraulic cylinders for translation. The positioning protrusion is specifically a multi-diameter end cap, used for coarse positioning of the inner flange as it falls onto the tooling table, and then the lifting head precisely positions the inner flange before it is lifted for welding.

[0013] Preferably, it also includes a transfer assembly and a transmission roller belt, the transmission roller belt being arranged vertically to the lifting and feeding assembly, and the transfer assembly being equipped with a pneumatic clamp that grips the inner flange of the transmission roller belt onto the plate.

[0014] Preferably, a positioning assembly is provided on the side of the conveyor belt near the horizontal frame, which includes a second cylinder mounted above the conveyor belt via a column, and the arm of the second cylinder is connected to the positioning plate.

[0015] Based on the above technical solutions, vertical transfer of the inner flange during conveying is achieved by setting a transfer assembly with pneumatic clamps; the positioning assembly enables precise positioning of the inner flange during disordered conveying on the transfer roller belt, facilitating subsequent precise clamping by the pneumatic clamps.

[0016] Preferably, the back of the positioning plate is V-shaped on one side of the horizontal frame, and multiple guide wheels are provided along the V direction inside the V-shaped surface.

[0017] Based on the above technical solutions, the V-shaped positioning plate can naturally guide and initially correct the inner flange that is being transported, gradually bringing the inner flange, which may have been deviated, to the center position. The guide rollers further enhance this centering positioning effect. With their smooth rolling performance, they effectively reduce frictional resistance, making the inner flange more stable and smooth as it approaches the final positioning point.

[0018] Preferably, the welding assembly has buffer positions for inner flanges at both the front and rear ends, and each buffer position consists of the same number of placement plates as the welding assembly.

[0019] Preferably, the transfer assembly includes a translation plate and a longitudinal guide post suspended above the conveyor roller belt. The translation plate and the longitudinal guide post are slidably connected. A first motor is provided on the translation plate, and the output end of the first motor is connected to the longitudinal guide post through a gear and rack.

[0020] Preferably, the translation plate is vertically slidably connected to the first lifting plate via a guide rail. The first lifting plate has a built-in gear and rack structure driven by a motor, and a pneumatic clamp is located at the bottom end of the first lifting plate.

[0021] Based on the above technical solutions, both the translation plate and the first lifting plate are driven by motors to achieve translation and lifting, which enables the pneumatic clamp to have the ability to lift and translate. The pneumatic clamp is a conventional structure.

[0022] In summary, this application includes the following beneficial technical effects:

[0023] 1. In this utility model, the first cylinder and the lifting head of the three-row lifting feeding assembly are set up to realize the pre-storage, welding and delivery of the dual-station inner flange, which makes the efficiency of assembly line welding higher.

[0024] 2. This utility model achieves the positioning of the inner flange on the placement plate regardless of its specifications or diameter by setting multiple arc-shaped limiting grooves on the positioning protrusion, thereby improving the accuracy of lifting, transporting, and reaching the welding position.

[0025] 3. This utility model has a simple structure. By setting a transfer assembly with pneumatic clamps, it realizes the vertical transfer during the conveying of the inner flange, and has subsequent precise clamping. Attached Figure Description
