Description

Technical Field

[0001] This application relates to the field of parts processing, and in particular to a nut welding system for parts processing. Background Technology

[0002] To improve the installation efficiency and connection stability of automotive parts, most automotive parts require pre-welding nuts to the mounting holes after processing and before installation. This allows bolts to be directly connected to the nuts through the mounting holes during installation, making the connection more convenient and preventing the nuts from loosening.

[0003] The existing method for welding nuts to automotive parts is usually as follows: first, the automotive parts are clamped and fixed, then the nut is placed on the automotive parts at the position to be welded, and the connection between the automotive parts and the nut is welded by a welding device. During the welding process, the nut is pressed to ensure the accuracy of the nut welding position and improve the strength of the nut weld.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: when welding the connection between automotive parts and nuts, it is necessary to weld the circumference of the nut, which requires adjusting the angle of the automotive parts during welding to complete the welding of the nut and the automotive parts around the circumference. This operation is complex and results in low welding efficiency. Summary of the Invention

[0005] To improve the efficiency of nut welding, this application provides a nut welding system for parts processing.

[0006] This application provides a nut welding system for parts processing, which adopts the following technical solution:

[0007] A nut welding system for machining parts includes a machining platform and a clamping mechanism and a welding mechanism disposed on the machining platform; the clamping mechanism includes a mounting plate and a driving component for moving the mounting plate on a plane, wherein the automotive parts are detachably disposed on the mounting plate; the welding mechanism includes a welding gun, a pushing component and a reversing component, wherein the pushing component drives the welding gun to move closer to or away from the mounting plate, and the reversing component drives the welding gun to move along the periphery of the mounting hole on the automotive parts.

[0008] By adopting the above technical solution, after the automotive parts are installed and fixed on the mounting plate, the nut is placed at the corresponding mounting hole of the automotive parts. The pushing component transports the mounting plate and automotive parts to the bottom of the welding gun, aligning the nut with the welding gun. The pushing component drives the welding gun to approach the mounting plate and starts welding the nut to the automotive parts. At the same time, the reversing component drives the welding gun to move around the mounting hole on the automotive parts, completing the circumferential welding and fixing of the nut. The welding angle is automatically adjusted, resulting in higher efficiency.

[0009] Optionally, the pushing assembly includes a linear push rod and a mounting plate. The linear push rod is disposed on the processing platform, the mounting plate is disposed on the output shaft of the linear push rod, and the welding gun is disposed on the mounting plate and perpendicular to the mounting plate.

[0010] By adopting the above technical solution, the linear push rod is activated, driving the mounting plate and welding gun closer to the mounting plate, thereby enabling the welding gun to accurately weld the connection between the nut and the automotive parts, improving the welding effect.

[0011] Optionally, the mounting plate is provided with an elastic telescopic rod, which is arranged parallel to the welding gun. The length of the elastic telescopic rod is not shorter than that of the welding gun. An abutment block is provided at the end of the elastic telescopic rod away from the mounting plate. The linear push rod drives the mounting plate and the elastic telescopic rod to move so that the abutment block abuts against the nut.

[0012] By adopting the above technical solution, the movement of the mounting plate drives the elastic telescopic rod and the abutment block to move. After the abutment block abuts against the nut, the nut and the automotive parts become more stable, thereby further improving the welding effect.

[0013] Optionally, the welding gun is slidably mounted on the mounting plate in a direction close to or away from the elastic telescopic rod, and the mounting plate is provided with an adjustment component for driving the movement of the welding gun.

[0014] By adopting the above technical solution and adjusting the distance between the welding gun and the elastic telescopic rod, when the mounting plate moves, the abutment block abuts against the nut, and at the same time, the welding gun head can be aligned with the position between the nut and the automotive parts. The position of the welding gun can be adjusted according to the specifications of the nut, making it more applicable.

[0015] Optionally, the adjustment assembly includes a slider and a threaded rod. The mounting plate has a groove that is adapted to slide the slider. The welding gun is mounted on the slider. The threaded rod is rotatably connected to the groove and one end extends to the periphery of the mounting plate. The threaded rod passes through the slider and is threadedly connected to the slider.

[0016] By adopting the above technical solution, rotating the threaded rod drives the slider to slide in the groove, thereby moving the position of the welding gun. The adjustment is convenient, and the slider moves the welding gun relatively stably, thus ensuring the accuracy of the welding gun during welding.

[0017] Optionally, the reversing assembly includes a motor, a gear, and a gear ring. The motor is mounted on the processing platform, the gear is coaxially mounted on the output shaft of the motor, and the gear ring is coaxially mounted on the mounting plate. The gear meshes with the gear ring, and the motor drives the gear to rotate the mounting plate.

[0018] By adopting the above technical solution, the starting motor drives the gear to rotate, thereby driving the gear ring and mounting plate to rotate, so that the welding gun can rotate around the circumference of the nut to complete the welding between the nut and the automotive parts. The structure is simple and the manufacturing cost is low.

[0019] Optionally, the drive assembly includes an X-axis conveyor track and a Y-axis conveyor track. The X-axis conveyor track is mounted on the machining platform, the Y-axis conveyor track is mounted on the output shaft of the X-axis conveyor track, and the mounting plate is horizontally mounted on the output shaft of the Y-axis conveyor track.

[0020] By adopting the above technical solution, the X-axis conveyor rail and the Y-axis conveyor rail work together to realize the movement of the mounting plate, thereby enabling the nuts on the automotive parts to move flexibly and accurately under the welding gun for welding, thus improving welding efficiency.

[0021] Optionally, the mounting plate is provided with multiple sets of cylinders, which together form a space for placing automotive parts. The mounting plate is provided with an infrared transmitter that emits infrared rays along the axis of the mounting hole, and the abutment block is provided with a signal receiver for receiving signals from the infrared transmitter. The signal receiver is electrically connected to the X-axis conveying track and the Y-axis conveying track.

[0022] By adopting the above technical solution, after the automotive parts are placed on the mounting plate, the cylinder is activated to clamp and fix the automotive parts. The infrared transmitter emits infrared rays that pass through the mounting hole and the nut. When the X-axis conveyor rail and the Y-axis conveyor rail first control the movement of the mounting plate, the nut moves to the bottom of the abutment block. Then, the signal receiver receives the signal emitted by the infrared transmitter for fine adjustment to detect the accuracy of the nut during welding.

[0023] Optionally, the processing platform is also equipped with an electromagnet, and the electromagnet is activated when the drive assembly moves the mounting plate below the electromagnet.

[0024] By adopting the above technical solution, after the nuts on the automotive parts are welded, the drive assembly transports the mounting plate to the area below the electromagnet. The electromagnet is energized and starts to detect the nuts on the automotive parts. If there are any nuts that have not been welded, they will be attracted by the electromagnet and detached from the automotive parts, making it easier for operators to detect and re-weld them.

[0025] This application provides a welding method for a nut welding system for parts processing, which adopts the following technical solution:

[0026] A welding method for a nut welding system for machining parts includes the following steps:

[0027] Step 1: Install and fix the car parts onto the mounting plate, and then place the nuts in the corresponding mounting holes of the car parts;

[0028] Step 2: Adjust the distance between the welding gun and the elastic telescopic rod according to the specifications of the nut;

[0029] Step 3: Using the drive assembly, the automotive parts are fed to the bottom of the welding gun, and the nut is aligned with the position of the welding gun;

[0030] Step 4: Push the component to drive the welding gun close to the mounting plate and start the welding gun to weld the nut to the automotive parts. At the same time, the reversing component drives the welding gun to move around the mounting hole on the automotive parts to complete the circumferential welding and fixing of the nut.

[0031] In summary, this application includes at least the following beneficial technical effects:

[0032] 1. After the automotive parts are installed and fixed on the mounting plate, the nut is placed in the corresponding mounting hole of the automotive parts. The pushing component transports the mounting plate and automotive parts to the bottom of the welding gun and aligns the nut with the welding gun. The pushing component drives the welding gun to approach the mounting plate and starts welding the nut to the automotive parts. At the same time, the reversing component drives the welding gun to move around the mounting hole on the automotive parts to complete the circumferential welding and fixing of the nut. The welding angle is automatically adjusted, which is more efficient.

[0033] 2. Start the linear push rod to drive the mounting plate and welding gun closer to the mounting plate, so that the welding gun can accurately weld the connection between the nut and the automotive parts. At the same time, the movement of the mounting plate drives the elastic telescopic rod and the abutment block to move. After the abutment block abuts against the nut, the nut and the automotive parts are relatively more stable, thereby improving the welding effect of the nut.

[0034] 3. Adjust the distance between the welding gun and the elastic telescopic rod. After the mounting plate moves, the abutment block abuts against the nut, and at the same time, the welding gun head can be aligned with the position between the nut and the automotive parts. The position of the welding gun can be adjusted according to the specifications of the nut, making it more versatile. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0041] This application discloses a nut welding system for parts processing.

[0042] Reference Figure 1 A nut welding system for parts processing includes a processing platform 1, a clamping mechanism 2, and a welding mechanism 3. Both the clamping mechanism 2 and the welding mechanism 3 are mounted on the processing platform 1. The clamping mechanism 2 clamps and fixes the automotive parts 4 to be processed, and the nut 5 is placed in the corresponding mounting hole 41 of the automotive parts 4. In order to achieve stable installation of the nut 5 before welding, the automotive parts 4 are provided with a placement groove that is connected to and coaxially arranged with the mounting holes 41. The nut 5 is placed in the placement groove before welding.

[0043] Reference Figure 1To facilitate the clamping and fixing of the automotive parts 4, the clamping mechanism 2 includes a horizontally arranged mounting plate 21. The automotive parts 4 are detachably mounted on the mounting plate 21. Multiple sets of cylinders 23 are fixedly connected to the mounting plate 21. The multiple sets of cylinders 23 form a space for placing the automotive parts 4. After the automotive parts 4 are placed on the mounting plate 21, the multiple sets of cylinders 23 are activated to clamp and fix the automotive parts 4.

[0044] To facilitate the movement of the automotive parts 4, the clamping mechanism 2 also includes a drive assembly 22 that drives the mounting plate 21 to move on a plane. In this embodiment, the drive assembly 22 includes an X-axis conveyor rail 221 and a Y-axis conveyor rail 222. Both the X-axis conveyor rail 221 and the Y-axis conveyor rail 222 are rodless cylinders. The X-axis conveyor rail 221 is fixedly connected to the processing platform 1, and the Y-axis conveyor rail 222 is fixedly connected to the output shaft of the X-axis conveyor rail 221. The mounting plate 21 is horizontally fixedly connected to the output shaft of the Y-axis conveyor rail 222. The X-axis conveyor rail 221 and the Y-axis conveyor rail 222 cooperate to enable the mounting plate 21 to move on a horizontal plane, thereby enabling the nut 5 on the automotive parts 4 to move flexibly and accurately to the corresponding position for welding, thus improving the welding accuracy.

[0045] Reference Figure 2 To weld the nut 5 on the automotive part 4, the welding mechanism 3 includes a welding gun 31, a pushing component 32, and a reversing component 33. The pushing component 32 drives the welding gun 31 to move closer to or away from the mounting plate 21. When the nut 5 on the automotive part 4 moves below the welding gun 31, the pushing component 32 drives the welding gun 31 to move closer to the automotive part 4. After the welding gun 31 is started, welding is achieved between the nut 5 and the automotive part 4. Then, the reversing component 33 drives the welding gun 31 to move along the periphery of the mounting hole 41 on the automotive part 4, thereby completing the welding between the nut 5 and the automotive part 4, making the weld between the nut 5 and the automotive part 4 uniform and the welding more stable.

[0046] Reference Figure 2 To enable the welding gun 31 to move towards the automotive part 4, the pushing assembly 32 includes a linear push rod 321 and a mounting plate 322. The linear push rod 321 is fixedly connected to the processing platform 1 in the vertical direction. The mounting plate 322 is disc-shaped and is coaxially rotatably connected to the output shaft of the linear push rod 321. The welding gun 31 is set on the mounting plate 322 and perpendicular to the mounting plate 21. When the linear push rod 321 is activated, the mounting plate 322 and the welding gun 31 are driven to approach the mounting plate 21, so that the welding gun 31 can accurately weld the connection between the nut 5 and the automotive part 4.

[0047] To improve the stability of nut 5 during welding, an elastic telescopic rod 323 is coaxially rotatably connected to the mounting plate 322. A spring is fitted around the outside of the elastic telescopic rod 323, which is driven to extend by the spring. The elastic telescopic rod 323 is arranged parallel to the welding gun 31, and the length of the elastic telescopic rod 323 is not shorter than that of the welding gun 31. An abutment block 324 is fixedly connected to the end of the elastic telescopic rod 323 away from the mounting plate 322. The linear push rod 321 drives the mounting plate 322 and the elastic telescopic rod 323 to move so that the abutment block 324 first abuts against nut 5. When the abutment block 324 abuts and presses against nut 5, the welding gun 31 can continue to move downward to a position close to the weld. When the welding gun 31 is welding, the stability of the thread is maintained.

[0048] Reference Figure 3-4 To be suitable for welding nuts 5 of different specifications, it is necessary to adjust the distance between the welding gun 31 and the elastic telescopic rod 323. The welding gun 31 is slidably mounted on the mounting plate 322 in the direction of approaching or moving away from the elastic telescopic rod 323. The mounting plate 322 is provided with an adjustment component 34 for driving the movement of the welding gun 31.

[0049] In this embodiment, the adjustment component 34 includes a slider 341 and a threaded rod 342. The mounting plate 322 has a groove 3221 that is adapted to slide the slider 341. The welding gun 31 is fixedly connected to the slider 341. The threaded rod 342 is rotatably connected to the groove 3221 and one end extends to the periphery of the mounting plate 322. The threaded rod 342 passes through the slider 341 and is threadedly connected to the slider 341. Rotating the threaded rod 342 causes the slider 341 to slide in the groove 3221, thereby moving the position of the welding gun 31.

[0050] The reversing assembly 33 includes a motor 331, a gear 332, and a gear ring 333. The motor 331 is fixedly mounted on the processing platform 1. The gear 332 is coaxially fixedly connected to the output shaft of the motor 331. The gear ring 333 is coaxially sleeved on the mounting plate 322. The gear 332 meshes with the gear ring 333. The motor 331 drives the gear 332 to rotate the mounting plate 322. The welding gun 31 can rotate around the circumference of the nut 5 to complete the welding between the nut 5 and the automotive part 4.

[0051] To further improve welding accuracy, an infrared transmitter 24 emitting infrared rays along the axis of the mounting hole 41 is fixedly installed on the mounting plate 21. A signal receiver 25 for receiving signals from the infrared transmitter 24 is fixedly installed on the abutment block 324. After the X-axis conveying rail 221 and Y-axis conveying rail 222 drive the mounting plate 322 to move, the nut 5 moves to below the abutment block 324. Before emitting infrared rays, the infrared transmitter 24 images the signal receiver 25. The signal receiver 25 is electrically connected to the X-axis conveying rail 221 and Y-axis conveying rail 222, thereby further driving and adjusting the nut 5 and the elastic telescopic rod 323 to be on the same axis, so that the welding gun 31 can accurately align with the weld between the nut 5 and the automotive part 4 for accurate welding.

[0052] Furthermore, an electromagnet 11 is fixedly installed on the processing platform 1. When the mounting plate 21 moves under the electromagnet 11, the electromagnet 11 is activated and can detect the nuts 5 on the automotive parts 4. If there are unwelded nuts 5, they will be attracted by the electromagnet 11 and the nuts 5 will detach from the automotive parts 4, making it easier for the operator to detect and re-weld them.

[0053] This application also discloses a welding method for a nut welding system for parts processing.

[0054] A welding method for a nut welding system for machining parts includes the following steps:

[0055] Step 1: Place the car part 4 on the mounting plate 21, start the cylinder 23 to clamp and fix the car part 4, and then place the nut 5 in the placement groove on the car part 4 that communicates with the mounting hole 41.

[0056] Step 2: According to the specifications of nut 5, rotate threaded rod 342 to drive sliding and welding gun 31 to move, and adjust the distance between welding gun 31 and elastic telescopic rod 323;

[0057] Step 3: The car part 4 is transported to the bottom of the welding gun 31 by the cooperation of the drive assembly 22, the X-axis conveying rail 221 and the Y-axis conveying rail 222, and the nut 5 is aligned with the position of the welding gun 31.

[0058] Step 4: Push component 32 drives welding gun 31 to approach mounting plate 21 and starts welding gun 31 to weld nut 5 to automotive part 4. At the same time, reversing component 33 drives welding gun 31 to move around mounting hole 41 on automotive part 4 to complete the circumferential welding and fixing of nut 5.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
