Description

Technical Field

[0001] This invention relates to the field of automotive parts welding technology, specifically to an automotive parts welding apparatus. Background Technology

[0002] The technological evolution of automotive component welding equipment can be traced back to ancient times, and its development is closely linked to changes in materials science, automation technology, and industrial needs. Currently, automotive component welding mainly relies on resistance welding (such as spot welding and projection welding), laser welding, gas shielded welding (such as CO2 welding and MIG / MAG welding), and emerging technologies such as ultrasonic welding.

[0003] In existing technologies, to address the issue of prolonged high-temperature operation during automotive parts welding equipment causing wear and tear on the welding torches and reducing their lifespan, two sets of welding torches are used. One set is kept active while the other is inactive, controlled by temperature sensors and control devices. However, employing two sets of welding torches, along with corresponding temperature sensors and control devices, significantly increases the manufacturing cost of the automotive parts welding equipment. Furthermore, the alternating use of the two sets of welding torches can lead to one set being idle for extended periods, resulting in low processing efficiency and further increasing production costs.

[0004] Based on this, a welding device for automotive parts is proposed, providing a solution to the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a welding device for automotive parts to solve the existing problems: the use of two sets of welding torch mechanisms, along with corresponding temperature sensing and control devices, greatly increases the manufacturing cost of the welding device for automotive parts; furthermore, the alternating use of the two sets of welding torch mechanisms will result in one set of welding torch mechanisms being idle for a long time, leading to low processing efficiency and further increasing production costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automotive parts welding device, comprising an operating table, wherein two clamping and positioning components are symmetrically mounted on the top of the operating table, and a welding torch mechanism is mounted on the top of one of the clamping and positioning components. The bottom of the operating table is equipped with a clamping and positioning drive assembly, and the top of the operating table is equipped with a cooling and heat-reducing assembly, which is located on one side of the welding torch mechanism.

[0007] Furthermore, the clamping and positioning drive assembly includes a T-shaped connecting plate and an electric push rod. The T-shaped connecting plate is fixed to the bottom of the operating table, and an electric push rod is fixed to one side of the T-shaped connecting plate. A T-shaped connecting block is fixed to the output end of the electric push rod. A connecting horizontal plate is also fixed to the bottom of the operating table. Two guide rods are fixed between the connecting horizontal plate and the T-shaped connecting plate. A first connecting block and a second connecting block are slidably connected to the outer side of the guide rods. The top of the T-shaped connecting block is fixedly connected to the bottom of the first connecting block. Both ends of the first connecting block are rotatably connected to a first transmission plate via pins. Both ends of the second connecting block are rotatably connected to a second transmission plate via pins. The first transmission plate and the second transmission plate, located at the same end, are rotatably connected by a drive shaft.

[0008] Furthermore, two guide slots are provided on the inner side of the operating table, and the two drive shafts are slidably connected to the inner side of the two guide slots respectively.

[0009] Furthermore, the clamping and positioning assembly includes a base, and the tops of the two drive shafts are rotatably connected to the base. The welding gun mechanism is mounted on the top of the base at one end. A support block is fixed inside the base, and a round rod is rotatably connected to the inner side of the support block. A threaded rod is fixed to one end of the round rod. An adjusting plate is slidably connected to the inner side of the base. A threaded hole is opened on the inner side of the adjusting plate, and the adjusting plate is threadedly connected to the threaded rod through the threaded hole. A clamping plate is fixed to the end of the adjusting plate away from the round rod.

[0010] Furthermore, two first guide plates are symmetrically fixed on both sides of the bottom of the base, and a first guide groove is provided on the top of the operating table corresponding to the first guide plate. The first guide plate is slidably connected to the inner side of the first guide groove.

[0011] Furthermore, two second guide plates are symmetrically fixed on both sides of the bottom of the adjustment plate, and two second guide grooves are opened inside the base, with the second guide plates slidably connected to the second guide grooves.

[0012] Furthermore, a clamping piece is fixed to the end of the clamp away from the adjusting plate, and the clamping piece is made of rubber.

[0013] Furthermore, a handle is fixed to the end of the round rod away from the threaded rod, and an anti-slip groove is provided on the outer side of the handle.

[0014] Furthermore, the cooling and heat-reducing assembly includes a connecting seat, a connecting box, and a fan. The top of the operating table is fixed to the connecting seat by bolts.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the cooperation of a clamping and positioning drive assembly, a clamping plate, and a cooling and heat dissipation assembly, requires only one welding torch mechanism. It eliminates the need for temperature sensing and control devices, allowing for cooling and heat dissipation of the idle welding torch mechanism during material changes. This effectively utilizes the working and idle times of the welding torch mechanism, ensuring processing efficiency and significantly reducing the manufacturing and usage costs of automotive parts welding devices. Furthermore, by moving the welding torch mechanism along with the base away from the welding position during material changes, it is easier to remove the welded automotive parts and to place new automotive parts to be welded subsequently.

Moreover, it eliminates the need to separately start the cooling mechanism when the welding torch mechanism is idle, making it more time-saving and labor-saving. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to the following: Figures 1-6 An automotive parts welding device includes an operating table 1, on the top of which two clamping and positioning components are symmetrically mounted, and a welding gun mechanism 2 is mounted on the top of one of the clamping and positioning components. The bottom of the operating table 1 is equipped with a clamping and positioning drive assembly, and the top of the operating table 1 is equipped with a cooling and heat-reducing assembly, which is located on one side of the welding torch mechanism 2.

[0023] Here, the clamping and positioning drive assembly includes a T-shaped connecting plate 3 and an electric push rod 4. The bottom of the operating table 1 is fixed with the T-shaped connecting plate 3, and the electric push rod 4 is fixed with one side of the T-shaped connecting plate 3. The output end of the electric push rod 4 is fixed with a T-shaped connecting block 5. The bottom of the operating table 1 is also fixed with a connecting horizontal plate 6. Two guide rods 7 are fixed between the connecting horizontal plate 6 and the T-shaped connecting plate 3. The outer side of the guide rods 7 is slidably connected with a first connecting block 8 and a second connecting block 9. The top of the T-shaped connecting block 5 is fixedly connected to the bottom of the first connecting block 8. Both ends of the first connecting block 8 are rotatably connected to a first transmission plate 10 by pins. Both ends of the second connecting block 9 are rotatably connected to a second transmission plate 11 by pins. The first transmission plate 10 and the second transmission plate 11 located at the same end are rotatably connected by a drive shaft 12.

[0024] By placing the automotive parts to be welded in the center of the top of the operating table 1, and then activating the electric push rod 4, the output end of the electric push rod 4 drives the T-shaped connecting block 5 to move, thereby moving the first connecting block 8 and the second connecting block 9 away from each other, so that the two drive shafts 12 will move closer to each other for driving.

[0025] Two guide slots 13 are also provided on the inner side of the operating table 1, and two drive shafts 12 are slidably connected to the inner side of the two guide slots 13 respectively. Thus, the movement direction is restricted by the cooperation of the drive shafts 12 and the guide slots 13, ensuring the accuracy of the movement of the drive shafts 12.

[0026] Therefore, only one welding torch mechanism 2 is needed, reducing the manufacturing and usage costs of the automotive parts welding device. Furthermore, by moving the welding torch mechanism 2 along with the base 14 away from the welding position during material changes, it is easier to pick up and put down automotive parts.

[0027] Example 2: Please refer to the following: Figures 1-3 , Figure 7 and Figure 8 This embodiment is an improvement on Embodiment 1. The clamping and positioning assembly includes a base 14. The tops of two drive shafts 12 are rotatably connected to the base 14 via bearings. The welding torch mechanism 2 is mounted on the top of the base 14 at one end. A support block 17 is fixed inside the base 14. A round rod 18 is rotatably connected to the inner side of the support block 17. A threaded rod 19 is fixed to one end of the round rod 18. An adjusting plate 20 is slidably connected to the inner side of the base 14. A threaded hole is provided on the inner side of the adjusting plate 20. The adjusting plate 20 is threadedly connected to the threaded rod 19 through the threaded hole. A clamping plate 21 is fixed to the end of the adjusting plate 20 away from the round rod 18. To facilitate the adjustment of the clamping distance, a handle 25 is fixed to the end of the round rod 18 away from the threaded rod 19. An anti-slip groove is provided on the outer side of the handle 25.

[0028] Two first guide plates 15 are symmetrically fixed on both sides of the bottom of the base 14. A first guide groove 16 is provided on the top of the operating table 1 at a position corresponding to the first guide plate 15. The first guide plates 15 are slidably connected to the inner side of the first guide groove 16. Two second guide plates 23 are symmetrically fixed on both sides of the bottom of the adjusting plate 20. Two second guide grooves 22 are provided inside the base 14. The second guide plates 23 are slidably connected to the second guide grooves 22.

[0029] Here, a clamping piece 24 is fixed to the end of the clamping plate 21 away from the adjusting plate 20. The clamping piece 24 is made of rubber, so that the rubber clamping piece 24 can protect the car parts when clamping them, and prevent damage to the car parts.

[0030] By activating the electric push rod 4, the output end of the electric push rod 4 drives the T-shaped connecting block 5 to move. Through the mutual approach of the two drive shafts 12, the two drive shafts 12 drive the two bases 14 to move. In turn, the bases 14 drive the two clamping pieces 24 to move closer together, thereby clamping and positioning the automotive parts.

[0031] When welding automotive parts of different specifications during use, the handle 25 can be turned, which in turn drives the threaded rod 19 to rotate via the round rod 18, thereby moving the adjusting plate 20 and adjusting the distance between the two clamping plates 24. This allows for matching, clamping, and positioning according to the specifications of the automotive parts.

[0032] The structural design of the clamping and positioning components allows for manual adjustment of the clamping distance, making it suitable for fixing automotive parts of various sizes and greatly improving the practicality of the device.

[0033] Example 3: Please refer to the following: Figures 1-3 , Figure 8 and Figure 9 This embodiment is an improvement on the second embodiment. The cooling and heat-reducing component includes a connecting seat 26, a connecting box 28 and a fan 30. The top of the operating table 1 is fixed to the connecting seat 26 by bolts. The top of the connecting seat 26 is rotatably connected to the support frame 27. The top of the support frame 27 is fixed to the connecting box 28. A fixing plate 29 is welded inside the connecting box 28. The fan 30 is fixed to one side of the fixing plate 29 by bolts. A filter plate 31 is fixed to one side of the connecting box 28 by screws. The top of the control panel 1 is fixed with a mounting plate 33 by screws. One end of the mounting plate 33 is fixed with a jog switch 34. One side of the base 14 is fixed with a fixing plate 35. The end of the fixing plate 35 near the jog switch 34 is fixed with a pressing plate 36. The fan 30 is electrically connected to the jog switch 34 by wires.

[0034] The inching switch 34 works by closing the contacts when pressed to conduct the circuit, and resetting to open the circuit when released. Common types include mechanical (metal spring) and electronic types, some with dustproof and high-temperature resistant designs suitable for various environments. The appropriate model can be selected based on the load; no specific limitation is made here, as long as the usage requirements are met. The contacts can be cleaned periodically during daily use.

[0035] The connecting box 28 also houses a filter element 32, located between the fan 30 and the filter plate 31. The filter element 32 can be made of activated carbon or sponge; in this case, sponge is used to filter out any debris that may be generated in the workshop. Since workshops are typically quite clean, in other embodiments, a screwdriver can be used to remove the filter plate 31 from the connecting box 28, and then the filter element 32 can be removed. A circulating cooling water pipe can then be installed on the side of the filter plate 31 furthest from the fan 30 for further rapid cooling.

[0036] After welding is completed, the output end of the driven electric push rod 4 retracts, causing the two clamping plates 24 to move away from each other, releasing the fixation on the automotive parts. The movement of the base 14 then moves the welding torch mechanism 2 away from the automotive parts. When the pressing plate 36 presses the jog switch 34, it drives the fan 30 to blow air onto the welding torch mechanism 2 for cooling. This improves the welding efficiency of the device and extends the service life of the welding torch mechanism 2. Furthermore, it eliminates the need to separately activate the cooling mechanism when the welding torch mechanism 2 is idle, saving time and effort.

[0037] Furthermore, through a series of improvements, only one welding torch mechanism 2 is needed. Without the need for temperature sensing and control devices, the idle welding torch mechanism 2 can be cooled and dissipated during material change. This effectively utilizes the working and idle time of the welding torch mechanism 2, ensures processing efficiency, and effectively reduces the manufacturing and usage costs of automotive parts welding devices.

[0038] In summary, the automotive parts welding device provided by this invention, during operation, first connects the device to an external power source, places the automotive parts to be welded in the center of the top of the operating table 1, and activates the electric push rod 4. The output end of the electric push rod 4 moves the T-shaped connecting block 5, which in turn moves the first connecting block 8. The first connecting block 8 and the second connecting block 9 move away from each other. Through the power transmission of the first transmission plate 10 and the second transmission plate 11, the two drive shafts 12 move closer together, causing the two drive shafts 12 to move the two bases 14. The bases 14 then move the two clamping plates 24 closer together, clamping and positioning the automotive parts. Simultaneously, the welding torch mechanism 2 moves closer to the automotive parts to be welded along with the bases 14, and the operator can then use the welding torch mechanism 2 to perform the welding work.

[0039] After welding is completed, the output end of the drive electric push rod 4 retracts, causing the two clamping plates 24 to move away from each other, releasing the fixation on the automotive parts. This allows for easy removal of the automotive parts, and the placement of new automotive parts to be welded. Simultaneously, the base 14 moves the welding torch mechanism 2 away from the automotive parts, thus reducing the impact of the welding torch mechanism 2 on the removal and placement of automotive parts while releasing the clamping and positioning. Furthermore, as the base 14 moves, it carries the pressing plate 36 towards the jog switch 34 via the fixing plate 35. When the pressing plate 36 presses against the jog switch 34, it drives the fan 30, causing the fan 30 to blow air towards the welding torch mechanism 2 for cooling. This significantly improves welding efficiency and extends the service life of the welding torch mechanism 2, and eliminates the need to separately activate the cooling mechanism when the welding torch mechanism 2 is idle, saving time and effort.

[0040] When welding automotive parts of different specifications, by rotating the handle 25, the handle 25 drives the threaded rod 19 to rotate through the round rod 18. This rotation is then transmitted through the threaded connection between the adjusting plate 20 and the threaded rod 19, driving the adjusting plate 20 to move. This adjusts the distance between the two clamping plates 24, adapting the specifications of the automotive parts to the specifications, thereby expanding the range of automotive parts specifications that the device is applicable to.
