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

The rotary multi-dimensional welding platform for automobile parts described in the present invention rotates with the baffle when two sections of the shaft rod are rotary welded. When the feed trough rotates to a position close to the feed port, liquid argon enters the first pipe along the feed port and is ejected from the second pipe, thereby protecting the welding points of the two sections of the shaft rod to prevent the shaft rod from reacting with oxygen in the air to form oxides during welding, and can release argon in a quantitative manner to avoid waste caused by continuous ejection of argon.

[0017] 2. The rotary multi-dimensional welding platform for automobile parts described in the present invention guides the argon gas in the flow groove through a plurality of guide plates, so that the argon gas is discharged from different outlets, and the outer sides of the two shaft rods are annularly covered, thereby providing better protection for the two shaft rods.

[0018] 3. The rotary multi-dimensional welding platform for automobile parts described in the present invention allows argon gas to enter the drainage ring after settling downwards through the wrapping of the concave surface of the drainage ring. The setting of the drainage ring can prevent the argon gas from quickly dispersing after being discharged, thereby increasing the residence time of the argon gas at the welding point of the two shaft rods. When the argon gas settles downward into the drainage ring, the fan is started to make the settled argon gas float upward, so that the settled argon gas can be reused, saving argon gas resources. Under the guiding effect of the convex surface of the drainage ring, the argon gas floating upwards can flow inwards and better fit with the shaft rod, thereby better protecting the welding point of the two shaft rods.

[0019] 4. The rotating multi-dimensional welding platform for automobile parts described in the present invention clamps and fixes two axle rods by a first clamping seat and a second clamping seat. When the aggregate box is controlled to move upward, the first clamping seat and the second clamping seat pull the two axle rods to perform a preliminary test on the firmness of the welding of the two axle rods.

[0020] 5. The present invention discloses a rotating multi-dimensional welding platform for automobile parts, which releases the clamping of the shaft rod by the first clamping seat, controls the upward movement of the aggregate box, and allows the two sliders to extend to the outside of the turntable at the same time through the arranged adjustment component. When the welding point of the two shaft rods moves to a position flush with the top block, the turntable is controlled by the motor to rotate clockwise. With the rotation of the turntable and the self-rotation of the two shaft rods, the grinding plate can grind the excess height of the two shaft rods after welding. After grinding the excess height of the weld, if there is a cold weld, 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.

[0021] 6. The rotating multi-dimensional welding platform for automobile parts described in the present invention continues to control the upward movement of the aggregate box after grinding the excess height. When the shaft rod below moves to a position flush with the top block, the motor controls the turntable to rotate counterclockwise, so that the inclined surface on one side of the top block hits the shaft rod below. By continuously hitting the shaft rod below, it is detected whether the two sections of the shaft rod are poorly welded, and when the motor is started, it drives the two sections of the shaft rod to rotate, thereby facilitating the impact detection of the top block on different positions of the shaft rod welding.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0025] like Figures 1 to 11As shown, the present invention provides a technical solution, a rotary multi-dimensional welding platform for automobile parts, comprising a base 1, a first hydraulic cylinder 2 is fixedly connected to the top of the base 1, a collection box 3 is fixedly connected to the output end of the first hydraulic cylinder 2, a feed pipe 31 is fixedly connected to the top of the collection box 3, a plurality of rotating shafts 27 are equidistantly connected to the inner wall of the collection box 3, the bottom of the rotating shaft 27 penetrates the collection box 3 and is fixedly connected to the second clamping seat 5, a first clamping seat 4 is rotatably connected to the top of the base 1 and is located directly below the second clamping seat 5, the first clamping seat 4 and the second clamping seat 5 are both provided with clamping assemblies, 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 collection box 3, the output end of the motor 25 penetrates the collection box 3, a second gear 29 is fixedly connected to the outer wall of the output end of the motor 25, and 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 a side close to the first clamping seat 4, and a welding head 14 is fixedly connected to the top of the bracket 13.

[0026] Through the above technical scheme, the two shaft rods are respectively inserted into the first clamping seat 4 and the second clamping seat 5, and the two shaft rods are clamped and fixed by the clamping assembly, so that the two shaft rods are respectively fixed on the first clamping seat 4 and the second clamping seat 5, the first hydraulic cylinder 2 is started to control the aggregate box 3 to move downward, drive the second clamping seat 5 to move downward, so that the two shaft rods are butted, and the connection of the two shaft rods is preliminarily welded through the welding head 14, and the motor 25 is started to drive the second gear 29 to rotate, so that the first gear 28 rotates, drives the rotating shaft 27 to rotate, and drives the second clamping seat 5 to rotate, and drives the two shaft rods and the first clamping seat 4 to rotate, thereby controlling the rotation of the two shaft rods while welding, so as to facilitate the rotary welding of the two shaft rods. After the welding is completed, the first hydraulic cylinder 2 is started to control the aggregate box 3 to move upward, and drives the second clamping seat 5 to move upward, thereby pulling the two shaft rods after welding, and detecting whether the two shaft rods are poorly welded by pulling.

[0027] Specifically, the clamping assembly includes a slot 6, the outer walls of the first clamping seat 4 and the second clamping seat 5 are both provided with a slot 6, the inner walls of the first clamping seat 4 and the second clamping seat 5 are both equidistantly fixedly connected with a plurality of second hydraulic cylinders 7, and the output end of the second hydraulic cylinder 7 extends to the interior of the slot 6 and is fixedly connected with a clamping plate 8.

[0028] Through the above technical solution, the shaft rod is inserted into the slot 6, and several second hydraulic cylinders 7 are started to drive several clamping plates 8 to approach each other. The shaft rod is clamped and fixed by the several clamping plates 8 approaching each other, so that the shaft rod is fixed on the first clamping seat 4 and the second clamping seat 5.

[0029] Specifically, the outer wall of the first hydraulic cylinder 2 is fixedly connected to the second pipe 16, the top of the second pipe 16 is fixedly connected to the first pipe 15, the top of the first pipe 15 passes through the aggregate box 3, the outer wall of the first pipe 15 is provided with a feed port 24, the outer wall of the output end of the motor 25 is fixedly connected to a baffle 26, the baffle 26 fits the outer wall of the feed port 24, and the outer wall of the baffle 26 is equidistantly provided with a plurality of feed grooves 46, the outer wall of the first pipe 15 is slidably connected to a sleeve 23, and the top of the sleeve 23 is fixedly connected to the aggregate box 3.

[0030] Through the above technical scheme, liquid argon is loaded into the collecting box 3 through the feed pipe 31, and the baffle 26 is arranged to fit the outer wall of the feed port 24 to block the feed port 24 to prevent liquid argon from entering the feed port 24. When the two sections of the shaft rods are rotary welded, the start motor 25 drives 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 feed port 24 is blocked. The liquid argon enters the first pipeline 15 along the feed port 24, and flows into the second pipeline 16 along the first pipeline 15, and is ejected from the second pipeline 16. The ejected liquid argon vaporizes into argon gas and floats to the welding point of the two sections of the shaft rods, thereby protecting the welding point of the two sections of the shaft rods to 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.

[0031] Specifically, one end of the second pipe 16 is fixedly connected to a collar 17, and the collar 17 is located directly above the first clamping seat 4. A flow groove 18 is provided inside the collar 17, and a plurality of air outlets 19 are equidistantly provided on the inner wall of the collar 17. The air outlets 19 are communicated with the flow groove 18. A guide plate 20 is fixedly connected to the inner wall of the flow groove 18 and close to the air outlet 19. The guide plate 20 is installed at an angle.

[0032] Through the above technical solution, the argon gas ejected from the second pipe 16 enters the circulation groove 18 and flows along the circulation groove 18. When passing through the guide plate 20, a part of the argon gas flows along the inclined surface of the guide plate 20 and is discharged from the gas outlet 19. Therefore, through the set several guide plates 20, the argon gas is discharged from different gas outlets 19, and the outer sides of the two shaft rods are annularly covered, thereby better protecting the two shaft rods.

[0033] Specifically, a drainage ring 30 is fixedly connected to the top of the first clamping seat 4, and the inner wall of the drainage ring 30 is configured to be corrugated.

[0034] Through the above technical solution, since the density of argon is greater than that of air, the argon will settle downwards after being ejected. The argon will enter the drainage ring 30 after settling downwards through the concave surface of the drainage ring 30. The setting of the drainage ring 30 can prevent the argon from dispersing quickly after being discharged, thereby increasing the residence time of the argon at the welding point of the two shaft sections.

[0035] Specifically, a support frame 45 is fixedly connected to the top of the base 1, and a turntable 33 is rotatably connected to the top of the support frame 45. Two sliders 34 are symmetrically slidably connected to the inner wall of the turntable 33. A first spring 35 is fixedly connected to one side of the slider 34, and 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, and one side of the top block 37 is set as a symmetrical inclined surface, and a second spring 36 is fixedly connected to the other side of the top block 37, and one end of the second spring 36 is fixedly connected to the slider 34. An adjustment component is provided at the bottom of the aggregate box 3, and a slide rod 32 is slidably connected to the outer wall of the output end of the motor 25, and the bottom of the slide rod 32 is fixedly connected to the turntable 33.

[0036] Through the above technical scheme, 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 material collection box 3 to move upward, driving the second clamping seat 5 to move upward, so that the two shaft rods move upward. While the material collection box 3 moves upward, the two sliders 34 are simultaneously extended to the outside of the turntable 33 through the provided adjustment component. When the lower shaft rod moves to a position flush with the top block 37, the motor 25 is started to control the slide bar 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, the second spring 36 is provided to make the inclined surface on one side of the top block 37 hit the lower shaft rod. When the welding is firm, as the turntable 33 rotates, the top block 37 is pushed toward the inside of the slider 34 under the pressure of the lower shaft rod, and the second spring 36 is compressed. Therefore, when the control slide bar 32 rotates counterclockwise, it can continuously hit the lower shaft rod, thereby detecting whether the two shaft rods are poorly welded. When the motor 25 is started, the two shaft rods are driven to rotate, thereby facilitating the top block 37 to detect the impact of different positions of the shaft rod welding.

[0037] Specifically, the adjustment component includes a swivel 41, which is arranged at the bottom of the aggregate box 3 and is rotatably connected to the aggregate box 3. Two fixed rods 42 are symmetrically fixedly connected to the bottom of the swivel 41. The bottom of the fixed rod 42 passes through the turntable 33 and is fixedly connected to a push rod 43. The bottom of the slider 34 is provided with an inclined groove 38 for cooperating with the push rod 43. The top and bottom of the turntable 33 are both provided with a first through groove 39. The interior of the slider 34 is provided with a second through groove 40, and the push rod 43 fits the inner walls of the first through groove 39 and the second through groove 40.

[0038] Through the above technical solution, the aggregate box 3 moves upward and drives the fixed rod 42 to move upward, so that the push rod 43 moves upward. The push rod 43 is inserted into the interior of the turntable 33 from the first through groove 39 below, and presses against the inclined groove 38 at the bottom of the slider 34. Under the squeezing of the push rod 43, the slider 34 is pushed to move to the outside of the turntable 33. As the aggregate box 3 continues to move upward, the push rod 43 passes through the second through groove 40 and the first through groove 39 above. When the aggregate box 3 moves downward, it drives the push rod 43 to move downward. When the push rod 43 is separated from the inclined groove 38, under the action of the first spring 35, the slider 34 is pulled to reset.

[0039] Specifically, a grinding plate 44 is fixedly connected to the inclined surface on one side of the sliding block 34 .

[0040] When the welding of the two shaft rods is completed, the first clamping seat 4 releases the clamping of the shaft rod, the first hydraulic cylinder 2 is started to control the material collecting box 3 to move upward, driving the second clamping seat 5 to move upward, so that the two shaft rods move upward. When the welding point of the two shaft rods moves to a position flush with the top block 37, the motor 25 is started to control the slide bar 32 to rotate clockwise, so that the turntable 33 rotates clockwise, driving the slide block 34 and the top block 37 to rotate clockwise. When the top block 37 rotates to a position close to the lower shaft rod, the second spring 36 is set to make the grinding plate 44 on the inclined surface of the other side of the top block 37 press against the welding point of the two shaft rods. With the rotation of the turntable 33, the grinding plate 44 can grind the excess height after the welding of the two shaft rods. After grinding the excess height of the weld, if there is a virtual weld, 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.

[0041] Specifically, a cavity 9 is opened on the inner wall of the first clamping seat 4, a fan 12 is arranged on the inner wall of the cavity 9, a plurality of air inlets 10 are opened at equal intervals on the outer wall of the first clamping seat 4, the air inlets 10 are communicated with the cavity 9, and an air outlet 11 is opened between the internal cavity 9 of the first clamping seat 4 and the slot 6.

[0042] Through the above technical solution, when the argon gas sinks downward into the guide ring 30, the fan 12 is started to blow air upward, so that the settled argon gas floats upward, and the settled argon gas is reused, saving argon gas resources. Moreover, under the guiding effect of the convex surface inside the guide ring 30, the argon gas floating upward can flow inward, better fit with the shaft rod, and better protect the welding effect of the two sections of the shaft rod.

[0043] Specifically, a sleeve box 21 is fixedly connected to the outer wall of the second pipe 16 , and a heating wire 22 is arranged inside the sleeve box 21 .

[0044] Through the above technical solution, the heating wire 22 is started while the two shaft sections are welded to heat the liquid argon passing through the second pipe 16, so that the liquid argon is quickly vaporized into argon gas.

[0045] When in use, the two shafts are respectively inserted into the first clamping seat 4 and the second clamping seat 5, and the plurality of second hydraulic cylinders 7 are started to drive the plurality of clamping plates 8 to approach each other. The shafts are clamped and fixed by the plurality of clamping plates 8 approaching each other, so that the shafts are fixed on the first clamping seat 4 and the second clamping seat 5. The first hydraulic cylinder 2 is started to control the aggregate box 3 to move downward, and the second clamping seat 5 is driven to move downward, so that the two shafts are butted, and the connection of the two shafts is preliminarily welded by the welding head 14. The motor 25 is started to drive the second gear 29 to rotate, so that the first gear 28 rotates, and the rotating shaft 27 rotates, so that the second clamping seat 5 rotates, and the two shafts and the first clamping seat 4 rotate. Thus, the rotation of the two shafts is controlled while welding, which is convenient for connecting the two shafts. Rotary welding is performed, liquid argon is loaded into the collecting box 3 through the feed pipe 31, and the baffle 26 is arranged to fit the outer wall of the feed port 24 to block the feed port 24 to prevent liquid argon from entering the feed port 24. When the two shafts are subjected to rotary welding, the motor 25 is started to drive the baffle 26 to rotate, so that the feed slot 46 on the outer wall of the baffle 26 rotates. When the feed slot 46 rotates to a position close to the feed port 24, the feed port 24 is blocked. The liquid argon enters the first pipeline 15 along the feed port 24 and flows into the second pipeline 16 along the first pipeline 15. When the two shafts are welded, the heating wire 22 is started to heat the liquid argon passing through the second pipeline 16, so that the liquid argon is quickly vaporized into argon gas, and the argon ejected from the second pipeline 16 The argon gas enters the flow groove 18 and flows along the flow groove 18. When passing through the guide plate 20, a part of the argon gas flows along the inclined surface of the guide plate 20 and is discharged from the gas outlet 19. Thus, the argon gas is discharged from different gas outlets 19 through the set guide plates 20, and the outer sides of the two shaft rods are covered in an annular shape, which has a better protection effect on the two shaft rods. Because the density of argon gas is greater than that of air, the argon gas will settle downward after being ejected, and the argon gas will enter the guide ring 30 after settling downward through the concave surface of the guide ring 30. The setting of the guide ring 30 can prevent the argon gas from dispersing quickly after being discharged, and increase the residence time of the argon gas at the welding point of the two shaft rods. When the argon gas settles downward into the guide ring 30, the fan 12 is started to blow air upward to make the settled argon gas settle downward. The descending argon gas floats upward, so that the settled argon gas can be reused, saving argon gas resources, and under the guidance effect of the inner convex surface of the guide ring 30, the argon gas floating upward can flow inward, better fit with the shaft rod, and better protect the welding place of the two shaft rods. After the welding is completed, 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, thereby pulling the two shaft rods after welding, and detecting whether the two shaft rods are poorly welded by pulling. Then, 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, it drives the fixed rod 42 to move upward, so that the top rod 43 moves upward.When the top block 37 rotates to a position close to the lower shaft rod, the grinding plate 44 on the inclined surface of the other side of the top block 37 is pressed against the welding place of the two shaft rods. With the rotation of the turntable 33 and 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 excess height of the weld, if there is a virtual welding, there will be an obvious gap at the joint of the two shaft rods, which is convenient for the processing personnel to judge whether it is necessary to repair the welding. After grinding the excess height, continue to control the aggregate box 3 Move upward, as the material collecting box 3 continues to move upward, the push rod 43 passes through the second through slot 40 and the first through slot 39 above. When the lower shaft rod moves to a position flush with the push block 37, the motor 25 is started to control the slide bar 32 to rotate counterclockwise, so that the turntable 33 rotates counterclockwise, driving the slide block 34 and the push block 37 to rotate counterclockwise. When the push block 37 rotates to a position close to the lower shaft rod, the second spring 36 is provided to make the inclined surface on one side of the push block 37 hit the lower shaft rod. When the welding is firm, as the turntable 33 rotates, the push block 37 is pushed to move toward the inside of the slide block 34 under the pressure of the lower shaft rod, and the second spring 36 is pressed. Therefore, when the control slide bar 32 rotates counterclockwise, it can continuously hit the lower shaft rod, thereby detecting whether the two shaft rods are poorly welded. When the motor 25 is started, the two shaft rods are driven to rotate, thereby facilitating the impact detection of the push block 37 on different positions of the shaft rod welding.
