Description

Technical Field

[0001] The invention belongs to the field of automobile parts processing, and specifically relates to a rotating multi-dimensional welding platform for automobile parts. Background Art

[0002] As the foundation of the automobile industry, auto parts are a necessary factor to support the sustainable and healthy development of the automobile industry. In particular, the current independent development and innovation in the automobile industry, which is in full swing, requires a strong parts system to support it. The independent brand and technological innovation of the whole vehicle need parts as the basis, and the independent innovation of parts has a strong driving force for the development of the whole vehicle industry. They influence and interact with each other. The welding process is indispensable in the processing of auto parts. The so-called welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. In the welding of automobile parts, welding is often required to splice multi-section shafts.

[0003] In the existing technology, when welding two shaft rods, the high temperature generated by welding makes the atoms on the metal surface active and easily undergoes oxidation reaction with oxygen in the air. Oxides will be mixed in the weld, which will reduce the quality of the weld. After welding, the welding position will produce weld excess height, which visually blocks the connection between the two shaft rods, making it impossible for construction workers to intuitively see whether the two shaft rods are fused, and therefore unable to determine whether further welding is needed. In addition, after welding the two shaft rods, it is not convenient to detect the firmness of the welding, and the shaft rods with poor welding cannot be removed in time.

[0004] To this end, the present invention provides a rotary multi-dimensional welding platform for automobile parts. Summary of the invention

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. For the rotary multi-dimensional welding platform for automotive parts of the present invention, when rotary welding two shaft rods, the baffle rotates accordingly. When the feeding groove rotates to a position close to the feeding port, liquid argon enters the first pipe along the feeding port and sprays out from the second pipe, thereby protecting the welding part of the two shaft rods, preventing the shaft rods from reacting with oxygen in the air to form oxides during welding, and being able to release argon quantitatively, avoiding waste caused by continuous spraying of argon.

[0018] 2. For the rotary multi-dimensional welding platform for automotive parts of the present invention, by arranging a plurality of flow guiding plates to guide the argon in the flow through groove, the argon is discharged from different air outlets, covering the outer sides of the two shaft rods in a ring shape, and having a better protection effect on the two shaft rods.

[0019] 3. For a rotary multi-dimensional welding platform for automotive parts according to the present invention, through the wrapping of the concave surface of the drainage ring, argon gas enters the drainage ring after settling downward. Through the setting of the drainage ring, it can prevent the rapid dispersion of argon gas after discharge, improve the residence time of argon gas at the welding joint of the two shaft rods. When the argon gas settles into the drainage ring downward, start the blower to make the settled argon gas float upward, so that the settled argon gas can be reused, saving argon gas resources. And under the guiding action of the convex surface of the drainage ring, the upward floating argon gas can flow inward, better fit with the shaft rod, and has a better protection effect on the welding joint of the two shaft rods.

[0020] 4. For a rotary multi-dimensional welding platform for automotive parts according to the present invention, the two shaft rods are clamped and fixed by the first clamping seat and the second clamping seat. When controlling the aggregate box to move upward, through the pulling of the two shaft rods by the first clamping seat and the second clamping seat, a preliminary detection of the welding firmness of the two shaft rods is carried out.

[0021] 5. For a rotary multi-dimensional welding platform for automotive parts according to the present invention, release the clamping of the shaft rod by the first clamping seat, control the aggregate box to move upward. Through the set adjustment component, the two sliders simultaneously extend outward from the turntable. When the welding joint of the two shaft rods moves to a position flush with the top block, control the turntable to rotate clockwise by the motor. As the turntable rotates, with the self-rotation of the two shaft rods, the grinding plate can grind the remaining height after the welding of the two shaft rods. After grinding the weld remaining height, if there is a lack of fusion, an obvious gap will appear at the joint of the two shaft rods, which is convenient for the processing personnel to judge whether welding needs to be supplemented.

[0022] 6. For a rotary multi-dimensional welding platform for automotive parts according to the present invention, continue to control the aggregate box to move upward after grinding the remaining height. When the lower shaft rod moves to a position flush with the top block, control the turntable to rotate counterclockwise by the motor, so that the inclined surface on one side of the top block impacts the lower shaft rod. By continuously impacting the lower shaft rod, it is detected whether there is a lack of fusion in the welding of the two shaft rods. And when the motor starts, it drives the two shaft rods to rotate, thus facilitating the impact detection of different positions of the shaft rod welding by the top block.

[0036] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0037] Such as Figures 1 to 11As shown in the figure, the present invention provides a technical solution, a rotary multi-dimensional welding platform for automotive parts, including a base 1. A first hydraulic cylinder 2 is fixedly connected to the top of the base 1. The output end of the first hydraulic cylinder 2 is fixedly connected to a collecting box 3. A feed pipe 31 is fixedly connected to the top of the collecting box 3. A plurality of rotating shafts 27 are rotatably connected to the inner wall of the collecting box 3 at equal intervals. The bottom of the rotating shaft 27 penetrates through the collecting box 3 and is fixedly connected to a second clamping seat 5. A first clamping seat 4 is rotatably connected to the top of the base 1 and directly below the second clamping seat 5. Clamping components are arranged inside both the first clamping seat 4 and the second clamping seat 5. A first gear 28 is fixedly connected to the outer wall of the rotating shaft 27. A motor 25 is fixedly connected to the top of the collecting box 3. The output end of the motor 25 penetrates through the collecting box 3. A second gear 29 is fixedly connected to the outer wall of the output end of the motor 25. The second gear 29 is meshed with the first gear 28. A bracket 13 is fixedly connected to the top of the base 1 and close to one side of the first clamping seat 4. A welding head 14 is fixedly connected to the top of the bracket 13.

[0038] Through the above technical solution, insert the two shaft rods into the first clamping seat 4 and the second clamping seat 5 respectively. Clamp and fix the two shaft rods through the clamping component, so that the two shaft rods are respectively fixed on the first clamping seat 4 and the second clamping seat 5. Start the first hydraulic cylinder 2 to control the collecting box 3 to move downward, drive the second clamping seat 5 to move downward, so that the two shaft rods are butted. Perform preliminary welding on the connection part of the two shaft rods through the welding head 14. Start the motor 25 to drive the second gear 29 to rotate, so that the first gear 28 rotates, drive the rotating shaft 27 to rotate, so that the second clamping seat 5 rotates, drive the two shaft rods and the first clamping seat 4 to rotate. Thus, control the two shaft rods to rotate while welding, which is convenient for rotary welding of the two shaft rods. After welding is completed, start the first hydraulic cylinder 2 to control the collecting box 3 to move upward, drive the second clamping seat 5 to move upward, and thus pull the two welded shaft rods. Detect whether the two shaft rods are poorly welded by pulling.

[0039] Specifically, the clamping component includes a slot 6. Slots 6 are opened on the outer walls of both the first clamping seat 4 and the second clamping seat 5. A plurality of second hydraulic cylinders 7 are fixedly connected to the inner walls of the first clamping seat 4 and the second clamping seat 5 at equal intervals. The output end of the second hydraulic cylinder 7 extends into the slot 6 and is fixedly connected to a clamping plate 8.

[0040] Through the above technical solution, insert the shaft rod into the slot 6, start a plurality of second hydraulic cylinders 7, drive a plurality of clamping plates 8 to approach each other, and clamp and fix the shaft rod through the plurality of mutually approaching clamping plates 8, so that the shaft rod is fixed on the first clamping seat 4 and the second clamping seat 5.

[0041] Specifically, a second pipe 16 is fixedly connected to the outer wall of the first hydraulic cylinder 2. The top of the second pipe 16 is fixedly connected to a first pipe 15. The top of the first pipe 15 penetrates through the aggregate box 3. A feed port 24 is formed in the outer wall of the first pipe 15. A baffle 26 is fixedly connected to the outer wall of the output end of the motor 25. The baffle 26 fits against the outer wall of the feed port 24. A number of feed grooves 46 are equidistantly formed in the outer wall of the baffle 26. A sleeve 23 is slidably connected to the outer wall of the first pipe 15. The top of the sleeve 23 is fixedly connected to the aggregate box 3.

[0042] Through the above technical solution, liquid argon is filled into the aggregate box 3 through the feed pipe 31. By setting the baffle 26 to fit against the outer wall of the feed port 24, the feed port 24 is blocked to prevent liquid argon from entering the feed port 24. When the two shaft rods are rotationally welded, the motor 25 is started to drive the baffle 26 to rotate, so that the feed grooves 46 on the outer wall of the baffle 26 rotate. When the feed grooves 46 rotate to a position close to the feed port 24, the blockage of the feed port 24 is lost, and the liquid argon enters the first pipe 15 along the feed port 24 and flows into the second pipe 16 along the first pipe 15, and is ejected from the second pipe 16. The ejected liquid argon vaporizes into argon gas and floats to the welding joint of the two shaft rods to protect the welding joint of the two shaft rods, prevent the shaft rods from reacting with oxygen in the air to form oxides during welding, and can release argon gas quantitatively to avoid waste caused by continuous ejection of argon gas.

[0043] Specifically, a collar 17 is fixedly connected to one end of the second pipe 16. The collar 17 is located directly above the first clamping seat 4. A flow channel 18 is formed inside the collar 17. A number of air outlets 19 are equidistantly formed in the inner wall of the collar 17. The air outlets 19 communicate with the flow channel 18. A deflector 20 is fixedly connected to the inner wall of the flow channel 18 and on the side close to the air outlet 19. The deflector 20 is inclined.

[0044] Through the above technical solution, the argon gas ejected from the second pipe 16 enters the flow channel 18 and flows along the flow channel 18. When passing through the deflector 20, a part of the argon gas flows along the inclined surface of the deflector 20 and is discharged from the air outlet 19. Thus, through the arrangement of a number of deflectors 20, the argon gas is discharged from different air outlets 19 to cover the outer sides of the two shaft rods in a circular shape, and the protection effect on the two shaft rods is better.

[0045] Specifically, a drainage ring 30 is fixedly connected to the top of the first clamping seat 4. The inner wall of the drainage ring 30 is wavy.

[0046] Through the above technical solution, since the density of argon is greater than that of air, the argon will precipitate downward after being ejected. Through the wrapping of the concave surface of the drainage ring 30, the argon enters the drainage ring 30 after precipitating downward. Through the setting of the drainage ring 30, it is possible to prevent the argon from quickly dispersing after being discharged, and improve the residence time of the argon at the welding joint of the two shaft rods.

[0047] Specifically, a support frame 45 is fixedly connected to the top of the base 1. The top of the support frame 45 is rotatably connected to a turntable 33. Two sliders 34 are symmetrically and slidably connected to the inner wall of the turntable 33. One side of the slider 34 is fixedly connected to a first spring 35. One end of the first spring 35 is fixedly connected to the turntable 33. A top block 37 is slidably connected to the inner wall of the slider 34. One side of the top block 37 is provided with symmetric inclined surfaces. The other side of the top block 37 is fixedly connected to a second spring 36. One end of the second spring 36 is fixedly connected to the slider 34. An adjusting assembly is provided at the bottom of the aggregate box 3. A sliding rod 32 is slidably connected to the outer wall of the output end of the motor 25. The bottom of the sliding rod 32 is fixedly connected to the turntable 33.

[0048] Through the above technical solution, after the welding of the two shaft rods is completed, the clamping of the shaft rod by the first clamping seat 4 is released, and the first hydraulic cylinder 2 is started to control the aggregate box 3 to move upward, driving the second clamping seat 5 to move upward, so that the two shaft rods move upward. While the aggregate box 3 moves upward, through the provided adjusting assembly, the two sliders 34 simultaneously extend out of the turntable 33. When the lower shaft rod moves to a position flush with the top block 37, the motor 25 is started to control the sliding rod 32 to rotate counterclockwise, so that the turntable 33 rotates counterclockwise, driving the slider 34 and the top block 37 to rotate counterclockwise. When the top block 37 rotates to a position close to the lower shaft rod, through the provided second spring 36, the inclined surface on one side of the top block 37 impacts the lower shaft rod. In the case of firm welding, as the turntable 33 rotates, under the extrusion of the lower shaft rod, the top block 37 is pushed into the slider 34, compressing the second spring 36. Thus, when the sliding rod 32 is controlled to rotate counterclockwise, the lower shaft rod can be continuously impacted, thereby detecting whether the two shaft rods are poorly welded. At the same time as the motor 25 is started, the two shaft rods are driven to rotate self - rotatably, which is convenient for the top block 37 to impact and detect different positions of the shaft rod welding.

[0049] Specifically, the adjusting assembly includes a rotating ring 41. The rotating ring 41 is arranged at the bottom of the aggregate box 3 and is rotatably connected to the aggregate box 3. Two fixing rods 42 are symmetrically and fixedly connected to the bottom of the rotating ring 41. The bottom of the fixing rods 42 penetrates through the turntable 33 and is fixedly connected to a top rod 43. The bottom of the slider 34 is provided with an inclined groove 38 for cooperating with the top rod 43. First through - grooves 39 are opened at the top and bottom of the turntable 33. Second through - grooves 40 are opened inside the slider 34. The top rod 43 abuts against the inner walls of the first through - groove 39 and the second through - groove 40.

[0050] Through the above technical solution, while the aggregate box 3 moves upward, it drives the fixed rod 42 to move upward, causing the ejector rod 43 to move upward. The ejector rod 43 inserts into the interior of the turntable 33 from the lower first through groove 39 and abuts against the inclined groove 38 at the bottom of the slider 34. Under the extrusion of the ejector rod 43, the slider 34 is pushed to move outward from the turntable 33. As the aggregate box 3 continues to move upward, the ejector rod 43 passes through the second through groove 40 and the upper first through groove 39. When the aggregate box 3 moves downward, it drives the ejector rod 43 to move downward. When the ejector rod 43 separates from the inclined groove 38, under the action of the first spring 35, the slider 34 is pulled back to its original position.

[0051] Specifically, a grinding plate 44 is fixedly connected to the inclined surface on one side of the slider 34.

[0052] Through the above technical solution, after the welding of the two shaft rods is completed, the clamping of the shaft rod by the first clamping seat 4 is released, and the first hydraulic cylinder 2 is started to control the upward movement of the aggregate box 3, driving the second clamping seat 5 to move upward, causing the two shaft rods to move upward. When the welded joint of the two shaft rods moves to a position flush with the top block 37, the motor 25 is started to control the clockwise rotation of the sliding rod 32, causing the turntable 33 to rotate clockwise, driving the slider 34 and the top block 37 to rotate clockwise. When the top block 37 rotates to a position close to the lower shaft rod, through the provided second spring 36, the grinding plate 44 on the inclined surface on the other side of the top block 37 abuts against the welded joint of the two shaft rods. As the turntable 33 rotates, in cooperation with the self-rotation of the two shaft rods, the grinding plate 44 can grind the excess height after the welding of the two shaft rods. After grinding the weld seam excess height, if there is a lack of fusion, an obvious gap will appear at the joint of the two shaft rods, which is convenient for the processing personnel to judge whether repair welding is required.

[0053] Specifically, a cavity 9 is provided in the inner wall of the first clamping seat 4. A blower 12 is provided on the inner wall of the cavity 9. A plurality of air inlets 10 are equidistantly provided on the outer wall of the first clamping seat 4. The air inlets 10 communicate with the cavity 9. An air outlet 11 is provided between the cavity 9 inside the first clamping seat 4 and the slot 6.

[0054] Through the above technical solution, when the argon gas sinks downward into the diversion ring 30, the blower 12 is started to blow upward, causing the settled argon gas to float upward, so that the settled argon gas can be reused, saving argon gas resources. And under the guiding action of the convex surface in the diversion ring 30, the upward-floating argon gas can flow inward, better fitting with the shaft rod, and having a better protection effect on the welded joint of the two shaft rods.

[0055] Specifically, a sleeve box 21 is fixedly connected to the outer wall of the second pipe 16. A heating wire 22 is provided inside the sleeve box 21.

[0056] Through the above technical solution, while welding the two shaft rods, the heating wire 22 is started to heat the liquid argon passing through the second pipe 16, causing the liquid argon to quickly vaporize into argon gas.

[0057] During use, insert the two shaft rods into the first clamping seat 4 and the second clamping seat 5 respectively. Start several second hydraulic cylinders 7 to drive several clamping plates 8 to approach each other. Clamp and fix the shaft rods through the several clamping plates 8 that approach each other, so that the shaft rods are fixed on the first clamping seat 4 and the second clamping seat 5. Start the first hydraulic cylinder 2 to control the aggregate box 3 to move downward, drive the second clamping seat 5 to move downward, so that the two sections of shaft rods are butted. Initially weld the connection of the two sections of shaft rods through the welding head 14. Start the motor 25 to drive the second gear 29 to rotate, make the first gear 28 rotate, drive the rotating shaft 27 to rotate, make the second clamping seat 5 rotate, drive the two sections of shaft rods and the first clamping seat 4 to rotate. Thus, control the rotation of the two sections of shaft rods while welding, which is convenient for rotary welding of the two sections of shaft rods. Load liquid argon into the aggregate box 3 through the feed pipe 31. By arranging the baffle 26 to fit the outer wall of the feed port 24, block the feed port 24 to prevent liquid argon from entering the feed port 24. When rotary welding the two sections of shaft rods, start the motor 25 to drive the baffle 26 to rotate, so that the feed groove 46 on the outer wall of the baffle 26 rotates. When the feed groove 46 rotates to a position close to the feed port 24, the blocking of the feed port 24 is lost, and liquid argon enters the first pipe 15 along the feed port 24 and flows into the second pipe 16 along the first pipe 15. While welding the two sections of shaft rods, start the heating wire 22 to heat the liquid argon passing through the second pipe 16, so that the liquid argon is quickly vaporized into argon gas. The argon gas ejected from the second pipe 16 enters the flow groove 18 and flows along the flow groove 18. When passing through the deflector 20, a part of the argon gas flows along the inclined surface of the deflector 20 and is discharged from the air outlet 19. Thus, through the arranged several deflectors 20, the argon gas is discharged from different air outlets 19 to annularly cover the outside of the two sections of shaft rods, and the protection effect on the two sections of shaft rods is better. Because the density of argon gas is greater than that of air, after the argon gas is ejected, it will precipitate downward. Through the wrapping of the concave surface of the drainage ring 30, the argon gas enters the drainage ring 30 after precipitating downward. Through the setting of the drainage ring 30, it can prevent the argon gas from quickly dispersing after being discharged, and improve the residence time of the argon gas at the welding joint of the two sections of shaft rods. When the argon gas sinks downward into the drainage ring 30, start the blower 12 to blow upward, so that the precipitated argon gas floats upward, and the precipitated argon gas is reused, saving argon gas resources. And under the guiding action of the convex surface of the drainage ring 30, the upward floating argon gas can flow inward and better fit the shaft rods, and the protection effect on the welding joint of the two sections of shaft rods is better. After welding is completed, start the first hydraulic cylinder 2 to control the aggregate box 3 to move upward, drive the second clamping seat 5 to move upward, thereby pulling the two sections of shaft rods after welding. Detect whether the two sections of shaft rods are poorly welded by pulling. Subsequently, release the clamping of the shaft rods by the first clamping seat 4. Start the first hydraulic cylinder 2 to control the aggregate box 3 to move upward, drive the second clamping seat 5 to move upward, so that the two sections of shaft rods move upward. While the aggregate box 3 moves upward, drive the fixed rod 42 to move upward, so that the ejector rod 43 moves upward.The ejector rod 43 is inserted into the interior of the turntable 33 from the first through groove 39 below and abuts against the inclined groove 38 at the bottom of the slider 34. Under the extrusion of the ejector rod 43, the slider 34 is pushed to move outward from the turntable 33. When the welded joint of the two shaft rods moves to a position flush with the top block 37, the motor 25 is started, and the slide rod 32 is controlled to rotate clockwise, so that the turntable 33 rotates clockwise, driving the slider 34 and the top block 37 to rotate clockwise. When the top block 37 rotates to a position close to the lower shaft rod, through the arranged second spring 36, the grinding plate 44 on the other inclined surface of the top block 37 abuts against the welded joint of the two shaft rods. As the turntable 33 rotates, in cooperation with the self-rotation of the two shaft rods, the grinding plate 44 can grind the remaining height after the welding of the two shaft rods. After grinding the weld seam remaining height, if there is a lack of fusion, an obvious gap will appear at the joint of the two shaft rods, which is convenient for the processing personnel to judge whether repair welding is needed. After grinding the remaining height, continue to control the aggregate box 3 to move upward. As the aggregate box 3 continues to move upward, the ejector rod 43 passes through the second through groove 40 and the first through groove 39 above. When the lower shaft rod moves to a position flush with the top block 37, the motor 25 is started, and the slide rod 32 is controlled to rotate counterclockwise, so that the turntable 33 rotates counterclockwise, driving the slider 34 and the top block 37 to rotate counterclockwise. When the top block 37 rotates to a position close to the lower shaft rod, through the arranged second spring 36, the inclined surface on one side of the top block 37 impacts the lower shaft rod. In the case of firm welding, as the turntable 33 rotates, under the extrusion of the lower shaft rod, the top block 37 is pushed to move into the interior of the slider 34, compressing the second spring 36. Thus, when the slide rod 32 is controlled to rotate counterclockwise, the lower shaft rod can be continuously impacted, thereby detecting whether the two shaft rods are lack of fusion. And when the motor 25 is started, it drives the two shaft rods to rotate self, so that it is convenient for the top block 37 to impact and detect different positions of the shaft rod welding.,
