Description

Technical Field

[0001] This application relates to the field of automotive fuel line processing technology, and more specifically, to an automotive fuel line spot welding device. Background Technology

[0002] In automotive fuel lines, the fuel line is a critical component of the fuel system. The welding quality of its outlet pipe and connector directly affects the safety of fuel delivery, and preventing leakage is the core requirement. In the current spot welding operation mode of manually placing the workpiece to be welded, the core pain point of the existing equipment is concentrated in the demolding process of the welded workpiece.

[0003] These types of devices generally lack efficient demolding structures. After welding, the workpieces, lacking a dedicated ejection or separation mechanism, must be removed manually by prying. This is not only cumbersome and significantly increases the labor intensity of workers, but also makes it difficult for users to handle the workpieces during removal due to the heat generated in the welded oil outlet pipes. Furthermore, the process of handling the oil outlet pipes and connectors can easily cause pressure or scratches, leading to workpiece damage and reduced yield. Simultaneously, the inefficient demolding operation prolongs the time required for a single process, restricting mass production efficiency, increasing production cycles and costs. Therefore, there is an urgent need for a spot welding device that can achieve rapid demolding of welded workpieces. Summary of the Invention

[0004] This application aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes an automotive fuel pipe spot welding device, which achieves precise positioning and fixation of the workpiece through the splicing structure of module one, module two and module three and the limiting effect of the insertion rod to improve welding quality. Relying on the electric push rod and the push plate, inclined rod, pull plate and ejector rod and other structures, the mold unfolding and workpiece ejection are integrated to solve the problem of part removal. The overall structure is compact, which can reduce incomplete welding and missed welding, avoid workpiece damage, reduce labor costs and failure rate, and balance welding quality, production efficiency and equipment stability.

[0005] According to an embodiment of this application, an automotive fuel outlet pipe spot welding device includes a processing base. A spot welding mechanism for welding the fuel outlet pipe is installed on the rear side of the processing base. An insertion mold is provided above the processing base and at the spot welding end of the spot welding mechanism. The insertion mold is composed of module one, module two, and module three. Wherein, a snap-fit ​​groove 1 is provided through the top joint of the top of the three modules, and a snap-fit ​​groove 2 and a slot are provided at the top joint of the two modules. The snap-fit ​​groove 1 and the snap-fit ​​groove 2 are used to install the oil outlet pipeline and the oil pipe connector for welding. The bottom of the insertion mold is provided with a pushing mechanism, which is used to unfold module one and module two in order to remove the welded oil outlet pipe and oil pipe connector.

[0006] According to some embodiments of this application, an oil outlet pipeline and an oil pipe connector are respectively placed in the first and second snap-fit ​​grooves, and the oil outlet pipeline and the oil pipe connector are welded together using a spot welding structure.

[0007] According to some embodiments of this application, the spot welding mechanism includes a welding device located behind the processing base, and welding guns are provided on the top and right side of the front side of the welding device. The welding guns are used to weld the surface interfaces of the oil outlet pipeline and the oil pipe connector. An electric push rod is provided on one side of the surface of the welding gun.

[0008] According to some embodiments of this application, the second module is connected to a fixing rod on the opposite side of the first module, and the inner surface of the first module is provided with a slot adapted to the fixing rod. When the first module and the second module are assembled, the fixing rod is inserted into the slot of the first module, which increases the stability of the connection between the first module and the second module.

[0009] According to some embodiments of this application, the pushing mechanism includes a base disposed at the bottom of the insertion mold, and pushing blocks located at the front and rear ends of the top of the base. The pushing blocks are provided with inclined rods, which are inclined and the pushing blocks and inclined rods are used in conjunction to adjust the relative positions of module one and module two.

[0010] According to some embodiments of this application, mounting grooves are provided at both the front and rear ends of the base, and a push plate is slidably provided in the mounting groove. The top of the push plate is connected to the bottom of the adjacent inclined rod, and the push plate can move linearly within the mounting groove.

[0011] According to some embodiments of this application, the surface of the push block is inclined with a push groove, and the inner surfaces of both module one and module two are provided with through grooves.

[0012] According to some embodiments of this application, push rods are provided through both sides of the bottom of the base, and top rods are symmetrically provided along the axis in the middle of the surface of the base. The top of the top rods extends through the inner cavity of the through hole, and through holes for the top rods to pass through are vertically provided on the surfaces of the base, module two, and module one.

[0013] According to some embodiments of this application, the surface of the top rod is fitted with a connecting block, and both ends of the connecting block are movably connected to a pull plate via a rotating shaft. A movable seat is movably connected to the middle of the surface of the pull plate, and the pull plate is inclined.

[0014] According to some embodiments of this application, an electric actuator is bolted to the bottom of the processing base, and the output end of the electric actuator is connected to a connecting plate, wherein the other end of the connecting plate is connected to the surface of an adjacent actuator.

[0015] The beneficial effects of this application are: 1. This solution offers precise positioning and reliable fixation, effectively improving welding quality. The device, through the splicing of Module 1, Module 2, and Module 3, forms matching snap-fit ​​grooves 1 and 2, which can precisely limit the positioning of the oil outlet pipeline and oil pipe connectors. Combined with the insertion and engagement of the fixing rod on Module 2 with the slot in Module 1, it ensures that the workpiece does not shift during welding, guarantees the alignment accuracy of the interface, and reduces the problems of incomplete welding and missing welding from the source.

[0016] 2. This solution incorporates a demolding and ejection structure, completely resolving the part removal problem. After welding, the electric push rod moves downward via the connecting plate. This causes the push plate to drive the inclined rod to slide and unfold modules one and two along the slide groove. Simultaneously, the pull plate moves the ejector rod upward, ejecting the workpiece from the snap-fit ​​groove. This eliminates the need for manual prying, preventing burns to operators from the high-temperature workpiece and avoiding squeezing and scratching during part removal, thus significantly improving the yield rate.

[0017] 3. This solution uses an electric push rod to drive the welding torch to move precisely into position. The electric push rod serves as the power source to achieve demolding and ejection. It works in conjunction with the conveying equipment to complete the pre-conveying of the workpiece. The connection between each process is smooth, reducing the time spent on manual intervention, effectively shortening the cycle of a single process, adapting to the needs of mass production, and reducing labor and time costs.

Detailed Implementation

[0022] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0023] like Figures 1 to 13As shown in the embodiment of this application, the automotive oil outlet pipe spot welding device includes a processing base 100. A spot welding mechanism for welding the oil outlet pipe is installed on the rear side of the processing base 100. The spot welding mechanism includes a welding device 120 located on the rear side of the processing base 100. Welding guns 140 are provided on the top and right side of the front side of the welding device 120. The welding guns 140 are used to weld the surface interface of the oil outlet pipe 300 and the oil pipe connector 310. The output end of the welding gun 140 is connected to the output end of the welding device 120 through a pipeline. An electric push rod 130 is provided on one side of the surface of the welding gun 140. The electric push rod 130 is a device such as an electric telescopic rod that can perform linear displacement. The fixed end of the electric push rod 130 is installed on the surface of the processing base 100. The output shafts of the two electric push rods 130 are respectively connected to the surface of the adjacent welding guns 140 through support plates. After the oil outlet pipeline 300 and the oil pipe connector 310 are placed in the first snap-fit ​​groove 240 and the second snap-fit ​​groove 250, the welding torch 140 is moved close to the connection between the oil outlet pipeline 300 and the oil pipe connector 310 by the electric push rod 130, and the welding torch 140 is used to weld the connection between the oil outlet pipeline 300 and the oil pipe connector 310.

[0024] Specifically, a conveying device 110 is installed at the front end of the processing base 100. The conveying device 110 can convey the oil outlet pipeline 300 and the oil pipe connector 310 so that the subsequent oil outlet pipeline 300 and the oil pipe connector 310 can be welded by the spot welding mechanism.

[0025] Specifically, an insertion mold 200 is provided above the processing base 100 and at the spot welding end of the spot welding mechanism. The insertion mold 200 is assembled from module one 210, module two 220 and module three 230. Among them, a snap-fit ​​groove 240 is provided through the top joint of module 1 210, module 2 220 and module 3 230, while a snap-fit ​​groove 250 and a slot 260 are provided at the top joint of module 2 220 and module 3 230. The snap-fit ​​groove 240 and the snap-fit ​​groove 250 are used to install the oil outlet pipeline 300 and the oil pipe connector 310 for welding. The welding torch 140 located on the side of the spot welding mechanism can be inserted into the slot 260 to weld the side and bottom interfaces of the oil outlet pipe 300 and the oil pipe connector 310. Module 220 is connected to a plug rod 221 on the opposite side of Module 1210. The inner surface of Module 1210 has a slot that matches the plug rod 221. When Module 1210 and Module 220 are assembled, the plug rod 221 is inserted into the slot of Module 1210, which increases the stability of the connection between Module 1210 and Module 220.

[0026] As a core component for positioning the oil outlet pipe 300 and the oil pipe connector 310, the insertion mold 200 adopts a modular splicing design, composed of module one 210, module two 220, and module three 230. Module three 230 is fixed to the top of the base 400 as a reference module. Module one 210 and module two 220 can slide relative to each other by engaging with the sliding groove 401 of the base 400 through the bottom slider 280. The snap-fit ​​groove one 240 formed after the top splicing of the three modules precisely matches the shape of the oil outlet pipe 300, while the snap-fit ​​groove two 250 fits the structure of the oil pipe connector 310, providing stable circumferential positioning of the workpiece. The insertion rod 221 on the side of module two 220 can be inserted into the slot of module one 210, further improving the overall integrity of the mold after splicing and preventing workpiece displacement during welding. In addition, the slot 260 between module two 220 and module three 230 provides operating space for the side welding gun 140, ensuring welding without dead angles.

[0027] Specifically, the insertion mold 200 is processed into module one 210, module two 220, and module three 230. Module one 210, module two 220, and module three 230 can be injection molded according to the required shape using injection molds. Alternatively, the irregular contours and mating dimensions of module one 210, module two 220, and module three 230 can be determined based on the structural parameters of the oil outlet pipe 300 and the oil pipe connector 310. High-strength alloy blanks are selected, and the base of each module is machined by CNC milling. The inner surface of module one 210 is precisely milled with slots that match the insertion rod 221 on module two 220. The insertion rod 221 is integrally milled on one side of module two 220, and a half-groove structure of the snap-fit ​​groove two 250 is machined on the top, with a pre-reserved slot 260 at the connection point with module three 230. Module three 230 serves as the reference module, with the other half-groove corresponding to the snap-fit ​​groove two 250 machined on the top, and a fixing structure for connection with the base 400 milled on the bottom. At the top joints of Module 1 210, Module 2 220, and Module 3 230, snap-fit ​​grooves 240 and 250, adapted to the workpiece, are machined by wire cutting. At the bottom of Module 1 210 and Module 2 220, sliders 280 are milled to ensure precise fit with the groove 401 of the base 400. After machining, the mating surfaces are precision-finished using a grinding machine to ensure the integrity and positioning accuracy after assembly.

[0028] The bottom of the insertion mold 200 is provided with a pushing mechanism, which is used to unfold module 1 210 and module 2 220 so as to remove the welded oil outlet pipe 300 and oil pipe connector 310.

[0029] At the same time, an oil outlet pipe 300 and an oil pipe connector 310 are respectively placed in the first snap-fit ​​groove 240 and the second snap-fit ​​groove 250. The oil outlet pipe 300 and the oil pipe connector 310 are welded together using a spot welding structure.

[0030] The pushing mechanism includes a base 400 disposed at the bottom of the insertion mold 200, and pushing blocks 430 located at the front and rear ends of the top of the base 400. The pushing blocks 430 are provided with inclined rods 420, which are inclined and the pushing blocks 430 and the inclined rods 420 work together to adjust the relative positions of module one 210 and module two 220. There are at least two pushing blocks 430, which are respectively located on the bottom side of module one 210 and module two 220.

[0031] Specifically, such as Figure 11 As shown, the two diagonal braces 420 are staggered on the front side; Specifically, module 3 230 is installed on the top of base 400, while module 1 210 and module 2 220 are slidably mounted on the top of base 400.

[0032] Specifically, the base 400 has sliding grooves 401 at both the front and rear ends of the top, and sliders 280 are connected to the bottom of module 1 210 and module 2 220 respectively. The sliders 280 extend into the inner cavity of the sliding grooves 401, so that module 1 210 and module 2 220 can slide on the top of the base 400.

[0033] The base 400 has mounting grooves 402 at both the front and rear ends, and a push plate 410 is slidably installed in the mounting groove 402. The top of the push plate 410 is connected to the bottom of the adjacent inclined rod 420, and the push plate 410 can move linearly within the mounting groove 402.

[0034] Specifically, the surface of the push block 430 is inclined with a push groove 431, and the inner surfaces of module one 210 and module two 220 are both provided with through grooves 222. The inclined rod 420 passes through the push groove 431 and extends into the through groove 222. When the push plate 410 drives the straight inclined rod 420 to move upward, the inclined rod 420 is inserted into the push groove 431, causing module one 210 and module two 220 to move relative to each other. Similarly, when the push block 430 moves downward, under the action of the inclined rod 420, module one 210 and module two 220 are moved in opposite directions.

[0035] Push rods 500 are provided through both sides of the bottom of the base 400. The top of the push rod 500 extends into the inner cavity of the base 400 and connects to the adjacent push plate 410. By moving the push rod 500, the push plate 410 can be moved. At least two top rods 510 are symmetrically arranged along the axis in the middle of the surface of the base 400. The top of the top rod 510 extends into the inner cavity of the through hole 270, and the bottom of the top rod 510 extends into the base 400 and the processing base 100 and extends to the bottom of the processing base 100. The connection between the top rod 510 and the processing base 100 is a sliding contact. The surfaces of the base 400, module two 220 and module one 210 are vertically provided with through holes 270 for the top rods 510 to pass through. The top rods 510 are slidably disposed in the inner cavity of the through holes 270.

[0036] The surface of the push rod 510 is fitted with a connecting block 522, and the two ends of the connecting block 522 are movably connected to the pull plate 520 through the rotating shaft. The middle of the surface of the pull plate 520 is movably connected to the movable seat 521. The top of the movable seat 521 is connected to the bottom of the processing base 100. The other end of the pull plate 520 is movably connected to the surface of the push rod 500 through the rotating shaft. The pull plate 520 is set at an angle. When the push rod 500 moves down, with the movable seat 521 as the origin, the push rod 500 pulls one end of the pull plate 520 down and the other end tilts up, thereby driving the push rod 510 to move up. The upward movement of the push rod 510 can push out the oil outlet pipe 300 in the snap-fit ​​groove 240, so that the user can quickly take out the processed oil outlet pipe 300 and oil pipe connector 310.

[0037] Similarly, when the push rod 500 is moved upward, the push rod 500 pulls one end of the pull plate 520 on one side upward, causing the other end of the pull plate 520 to tilt downward, which in turn pulls the top rod 510 downward into the through hole 270.

[0038] An electric actuator 540 is bolted to the bottom of the machining base 100. The output end of the electric actuator 540 is connected to a connecting plate 530. The other end of the connecting plate 530 is connected to the surface of the adjacent actuator 500. Thus, using the electric actuator 540 as a power source, when the output end of the electric actuator 540 extends downward, the connecting plate 530 can pull the actuator 500 downward. When the output end of the electric actuator 540 retracts upward, the connecting plate 530 can pull the actuator 500 upward.

[0039] Specifically, the automotive oil pipe spot welding device of this application includes a controller, which can be fixedly installed on the side of the processing base 100. The controller is electrically connected to the electric push rod 130, electric push rod 540, welding equipment 120, and conveying equipment 110 via wires, forming a complete control loop. Operators can preset parameters for each process through the controller. When the conveying equipment 110 delivers the workpiece to the designated position, the controller receives a signal and triggers the electric push rod 130 to move the welding torch 140 to the welding position. Then, the welding equipment 120 is activated to complete the spot welding. After welding, the controller triggers the electric push rod 540 after a delay, controlling its output end to extend and then retract, thus linking the mold unfolding, workpiece ejection, and resetting actions. The controller can precisely control the timing and stroke of each component's actions to avoid action conflicts. It also has a fault alarm function, promptly stopping the machine when an electrical component malfunctions, ensuring the safe and stable operation of the device. The control principle of this controller is existing technology and will not be described in detail in this solution.

[0040] Specifically, the working principle of the automotive oil pipe spot welding device is as follows: First, the conveying equipment 110 transports the oil pipe 300 and oil pipe connector 310 to be processed to the insertion mold 200 above the processing base 100. The operator places the oil pipe 300 into the snap-fit ​​groove 240 formed by the splicing of module one 210, module two 220 and module three 230, and places the oil pipe connector 310 into the snap-fit ​​groove 250 formed by module two 220 and module three 230. At this time, the insertion rod 221 on module two 220 is inserted into the slot of module one 210 to ensure that the insertion mold 200 is assembled as a whole. Once the connection is stable, the interface between the oil outlet pipe 300 and the oil pipe connector 310 is aligned for welding. Subsequently, the welding equipment 120 is started, and the electric push rod 130 mounted on the surface of the processing base 100 pushes its output shaft to move the welding gun 140 connected to the support plate, so that the top and right welding guns 140 are close to the corresponding interfaces between the oil outlet pipe 300 and the oil pipe connector 310, respectively. The side welding gun 140 is inserted into the slot 260. The welding equipment 120 delivers welding energy to the welding gun 140 through the pipe, and the welding gun 140 performs spot welding on the interface between the oil outlet pipe 300 and the oil pipe connector 310. After welding, the electric actuator 540 at the bottom of the machining base 100 is activated, its output end extends downward and pulls the push rod 500 downward through the connecting plate 530. The push rod 500 drives the push plate 410 in the mounting groove 402 of the base 400 to move downward, and the push plate 410 drives the inclined rod 420 connected at the top to move downward, so that module one 210 and module two 220 slide relative to each other along the sliding groove 401 of the base 400 through the bottom slider 280. On the other hand, the push rod 500 pulls the connecting block 522 and the top rod 510 upward through the pull plate 520 with the movable seat 521 as the fulcrum. The top rod 510 moves along the base 400, The through holes 270 of Module 220 and Module 1210 move upward, pushing out the oil outlet pipe 300 and oil pipe connector 310 that have been welded in the snap-fit ​​groove 1 240 and snap-fit ​​groove 2 250, making it convenient for workers to pick them up. After the parts are picked up, the output end of the electric push rod 540 retracts upward, driving the push rod 500 to move upward through the connecting plate 530. The push rod 500 drives the push plate 410 and the inclined rod 420 to move upward, so that Module 1210 and Module 220 are reset and spliced. At the same time, the push rod 500 drives the top rod 510 to move downward back into the through hole 270 through the pull plate 520, and the device returns to its initial state for the next round of spot welding.

[0041] It should be noted that the specific models and specifications of the electrical components used in this device, such as the controller, electric push rod 130, electric push rod 540, welding equipment 120, and conveying equipment 110, need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technology in this field, so they will not be described in detail here.

[0042] The power supply and operating principle of the aforementioned controller, electric push rod 130, electric push rod 540, welding equipment 120, and conveying equipment 110 are clear to those skilled in the art and will not be described in detail here.
