[0014] Beneficial effects

[0015] The present invention provides a mechanical part welding mechanism with a correction function. Compared with the prior art, the following beneficial effects are achieved:

[0016] (1) Through the setting of the clamping center alignment mechanism, the adaptive clamping of two cylindrical parts with different diameters is realized, meeting the use of cylindrical parts with different thicknesses. While clamping, the welding surface can be automatically centered, effectively improving the welding accuracy, avoiding the phenomenon of welding skew of the two parts, and at the same time preventing the other end of the two cylindrical parts from tilting downward under the influence of gravity after being clamped at one end by the chuck, and can effectively maintain the horizontal.

[0017] (2) Through the setting of the swinging air jet protection component, when the clamping center alignment mechanism works, through the upward movement of the U-shaped plate, the fan can be synchronously driven to move to the welding position, and then the fan performs automatic reciprocating up and down swinging to blow air around the welding position, blowing the protective gas to the welding area, forming a stable protective gas layer in the welding area, preventing the metal from contacting with air and oxidizing during the welding process, thereby reducing the generation of defects such as pores and welding slag. At the same time, the swinging air blowing of the fan can also accelerate the temperature drop after welding and improve the cooling speed.

[0018] (3) Through the setting of the slag removal component, by using the up and down swinging of the fan, the brush bristles can be synchronously driven to swing. During the swinging process of the brush bristles, the welding slag at the welding position can be brushed off and removed, thereby keeping the welding position clean and improving the welding quality.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] The embodiments of the present invention provide three technical solutions, specifically including the following embodiments:

[0030] Embodiment 1: Please refer to Figures 1 - 4 , a mechanical part welding mechanism with a correction function, including a base 1. Above the base 1, there are two cylindrical parts with different diameters. To ensure the stability of the base 1, two support feet are fixed at the bottom of the base 1 as shown in the attached Figure 1 of the specification. On the base 1, there is a clamping center alignment mechanism 2 for centering the welding surfaces of the two cylindrical parts.

[0031] The clamping center alignment mechanism 2 includes a mounting frame 21 fixed on the top of the base 1. The mounting frame 21 is U-shaped. This shape design can provide sufficient space for the installation of other components. On the mounting frame 21, two mounting seats I 22 and four mounting seats II 23 are fixed. The mounting seats I 22 are arranged vertically on the mounting frame 21, and the mounting seats II 23 are arranged obliquely on the mounting frame 21. Refer to the attached Figure 4As shown, a first sliding seat 24 is slidably connected inside a first mounting seat 22. A first rack 25 is fixed to the top of the first sliding seat 24, and a first clamping seat 26 is fixed to the top of the first rack 25. A second sliding seat 27 is slidably connected to the inner surface of a second mounting seat 23. The cross-sections of the first sliding seat 24 and the second sliding seat 27 are both trapezoidal. Trapezoidal grooves are also provided inside the first mounting seat 22 and the second mounting seat 23. The sizes of the first sliding seat 24, the second sliding seat 27, and the trapezoidal grooves are adapted to each other. This trapezoidal design can prevent the first sliding seat 24 and the second sliding seat 27 from sliding out of the first mounting seat 22 and the second mounting seat 23. To improve the smoothness of the first sliding seat 24 sliding inside the first mounting seat 22, a high-performance grease is applied to the inner wall of the trapezoidal groove of the first mounting seat 22. This grease has good high-temperature resistance and anti-wear performance, can effectively reduce the friction between the first sliding seat 24 and the first mounting seat 22, and extend the service life of the mechanism. The second mounting seat 23 is also smeared with grease. A second rack 28 is fixed to one side of the second sliding seat 27, and a second clamping seat 29 is fixed to the second rack 28. Ball bearings 210 are rotatably connected to both the first clamping seat 26 and the second clamping seat 29. After the first clamping seat 26 and the second clamping seat 29 clamp a cylindrical part, the ball bearings 210 are in contact with the outer surface of the cylindrical part. The setting of the ball bearings 210 can prevent the cylindrical part from being affected by the clamping of the second clamping seat 29 and the first clamping seat 26 during rotation. The ball bearings 210 are installed inside the first clamping seat 26 and the second clamping seat 29 through rotating shafts, and multiple ball bearings 210 are provided. A driving assembly 4 is provided on the mounting frame 21 to drive the two first clamping seats 26 and the four second clamping seats 29 to perform radial contraction and clamping.

[0032] The driving assembly 4 includes a first cylinder 41 fixed to the bottom of the mounting frame 21. Specifically, the first cylinder 41 is installed at the bottom of the base 1, and the mounting frame 21 is fixed to the top of the base 1. The first cylinder 41 is controlled by an external switch and is electrically connected to an external power supply. To ensure the working stability and reliability of the first cylinder 41, pressure sensors and flow sensors are installed at both the air inlet and the air outlet of the first cylinder 41. The pressure sensor can monitor the air pressure inside the cylinder in real time, and the flow sensor can accurately control the gas flow. Through the analysis and processing of the sensor data by the control system, precise control of the first cylinder 41 can be achieved, ensuring that the clamping force of the second clamping seat 29 and the first clamping seat 26 meets the requirements and preventing the phenomenon of over-clamping and damaging the parts. The output end of the first cylinder 41 is fixed with a U-shaped plate 42. A first gear 43 is rotatably connected between the opposite sides of the U-shaped plate 42. Through grooves 44 are provided on the opposite sides of the inner wall of the mounting frame 21. Both of the two through grooves 44 are communicated with the inside of the first mounting seat 22. Specifically, both of the two through grooves 44 are communicated with the trapezoidal groove inside the first mounting seat 22.

[0033] On one side of each of the two sliding seats 24, a third rack 45 is fixed. Both of the two third racks 45 penetrate through the through groove 44 and extend to the outside of the through groove 44, and the third rack 45 slides in the through groove 44. The first gear 43 meshes with the two third racks 45. When the first gear 43 rotates, it can make the two third racks 45 move adaptively, and can be automatically adjusted adaptively according to the diameter of the cylindrical part. To further improve the accuracy and stability of the meshing between the first gear 43 and the third rack 45, the tooth surface of the first gear 43 is hardened to increase the hardness and wear resistance of the tooth surface. At the same time, the tooth profile of the third rack 45 is precisely machined to ensure that the meshing clearance between the two is within a reasonable range. Four second gears 46 are rotatably connected to both sides of the mounting frame 21, and the second gears 46 mesh with the second rack 28 and the first rack 25.

[0034] Through the setting of the clamping center alignment mechanism 2, the adaptive clamping of two cylindrical parts with different diameters is realized, meeting the use of cylindrical parts with different thicknesses. At the same time of clamping, the welding surface can be automatically centered, effectively improving the welding accuracy, avoiding the phenomenon of skew welding of the two parts, and preventing the other end of the two cylindrical parts from tilting downward under the influence of gravity after one end is clamped by the chuck 9, and can effectively maintain the horizontal.

[0035] Embodiment 2: On the basis of Embodiment 1, see Figures 5 - 6 As shown, a swinging air jet protection assembly 5 is arranged on one side of the U-shaped plate 42. The swinging air jet protection assembly 5 includes an L-shaped plate 51 fixed on one side of the U-shaped plate 42. The top of the L-shaped plate 51 is fixed with a U-shaped frame 52, and the top of the U-shaped frame 52 is fixed with a fixed frame 53. To enhance the structural strength and stability of the fixed frame 53, the fixed frame 53 is made of high-strength aluminum alloy material, and reinforcing ribs are arranged inside it, which can effectively improve the bearing capacity of the fixed frame 53.

[0036] A motor 54 is fixed on one side of the fixed frame 53. The motor 54 is controlled by an external switch and is electrically connected to an external power supply. The output end of the motor 54 is fixed with a turntable 55. The inner surface of the turntable 55 is slidably connected with a moving rod 56. The moving rod 56 slides left and right on the inner surface of the turntable 55. Refer to the attached Figure 6As shown in the figure, a rod sleeve 57 is fixed at one end of the moving rod 56. A cross bar 58 is fixed between the opposite sides of the fixed frame 53. Two rotating plates 59 are rotatably connected to the cross bar 58. A connecting rod 510 is fixed between the opposite sides of the two rotating plates 59. The rod sleeve 57 slides on the connecting rod 510, and the sizes of the rod sleeve 57 and the connecting rod 510 are adapted to each other. A blower 511 is fixed between one sides of the two rotating plates 59. The blower 511 is controlled by an external switch and is electrically connected to an external power supply. The air inlet of the blower 511 is communicated with an air inlet pipe, and an external welding protection gas is introduced into the air inlet pipe. After the blower is started, the protection gas can be blown to the welding part of the two cylindrical parts, so as to form a protection at the welding part to prevent oxidation. The protection gas can specifically be argon. The density of argon is greater than that of air, and a stable protection gas layer can be formed in the welding area, effectively isolating the welding area from the air and preventing harmful effects of oxygen, nitrogen, etc. in the air on the welding molten pool. Since argon does not participate in the chemical reaction during the welding process, it can provide a pure environment for welding, thereby improving the quality of the welding joint, reducing defects such as pores and welding slag. To ensure the stable supply and precise control of the protection gas, a gas flow regulating valve and a pressure stabilizer are installed on the air inlet pipe. The gas flow regulating valve can accurately regulate the flow rate of the protection gas according to the requirements of the welding process, and the pressure stabilizer can ensure that the gas pressure in the air inlet pipe remains stable and is not affected by the pressure fluctuation of the external gas source.

[0037] Through the setting of the swing jet protection assembly 5, when the clamping center alignment mechanism 2 works, through the upward movement of the U-shaped plate 42, the blower 511 can be synchronously driven to move to the welding part, and then the blower 511 performs automatic reciprocating up and down swing to blow air around the welding part, blowing the protection gas to the welding area to form a stable protection gas layer in the welding area, preventing the metal from contacting the air and oxidizing during the welding process, thereby reducing the generation of defects such as pores and welding slag. At the same time, the swing blowing of the blower 511 can also accelerate the temperature drop after welding and improve the cooling speed.

[0038] A slag removal assembly 6 is arranged at the top of the blower 511. The slag removal assembly 6 includes a folding plate 61 fixed at the top of the blower 511. A cross plate 62 is fixed on one side of the folding plate 61. A brush hair 63 is fixed on one side of the cross plate 62. The brush hair 63 is specifically made of steel wire brush hair. The steel wire has high hardness and strength, can effectively brush off the welding slag, has good wear resistance, is not easy to deform or break during the brushing process, and can withstand large frictional force and pressure.

[0039] Through the setting of the slag removal assembly 6, by using the up and down swing of the blower 511, the brush hair 63 can be synchronously driven to swing. During the swinging process of the brush hair 63, the welding slag at the welding part can be brushed off and removed, thereby keeping the welding part clean and improving the welding quality.

[0040] Example 3: On the basis of Example 2, seeFigures 7 - 8 As shown in the figure, a chassis 7 is fixed on one side of the top of the base 1, and a fixing seat 8 is fixed on the other side of the top of the chassis 7. Chucks 9 are fixed on the driving shaft of the chassis 7 and the rotating shaft of the fixing seat 8. Specifically, a motor is installed inside the chassis 7, and the driving shaft of the motor is fixed to the chuck 9. The two chucks 9 clamp one end of two cylindrical parts. The chuck 9 is a prior art. By starting the cylinder inside, the four jaws are driven to radially contract and clamp, thereby clamping one end of the two cylindrical parts. To improve the clamping accuracy and stability of the chuck 9, anti-slip patterns and pressure sensors are provided on the jaws of the chuck 9. The anti-slip patterns can increase the friction between the jaws and the parts, preventing the parts from sliding during clamping. The pressure sensor can monitor the clamping force of the jaws on the parts in real time. When the clamping force exceeds the set value, the control system will send an alarm signal to remind the operator to make adjustments and avoid damaging the parts due to excessive clamping force.

[0041] A vertical frame 10 is also fixed on the top of the base 1. A second cylinder 11 is fixed on the top of the vertical frame 10. The second cylinder 11 is controlled by an external switch and is electrically connected to an external power supply. The output end of the second cylinder 11 is fixed with a fixing plate 12. A welding seat 13 is fixed on one side of the fixing plate 12. A welding torch 14 is provided at the bottom of the welding seat 13. The welding torch 14 is a prior art. The welding torch 14 is controlled by an external switch and is electrically connected to an external power supply.

[0042] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0043] During operation, two cylindrical parts with different diameters are placed between two chucks 9. The two cylindrical parts are clamped at one end by the chucks 9. Further, the first cylinder 41 is activated, causing the first cylinder 41 to drive the first gear 43 to move upward. The first gear 43 drives the two third racks 45 to move upward. Then, the third racks 45 drive the first slide 24 to slide upward. Further, the first rack 25 drives the second gear 46 to rotate. Then, when the second gear 46 rotates, it drives the second rack 28 to move crosswise, causing the second slide 27 to slide within the second mounting seat 23. Further, the first clamping seat 26 and the second clamping seat 29 cooperate to clamp the two cylindrical parts. By fine-tuning the rotation of the first gear 43, it can automatically adaptively clamp according to the diameters of the two cylindrical parts, align the welding surfaces of the two cylindrical parts at the center, and at the same time prevent the two cylindrical parts from tilting downward under the influence of gravity, effectively maintaining horizontal. Further, the motor in the chassis 7 is activated, causing the drive shaft to drive the chucks 9 and the two cylindrical parts to rotate. Then, the second cylinder 11 is activated, causing the second cylinder 11 to drive the welding torch 14 to move downward to weld the contact surfaces of the two cylindrical parts. During the upward movement of the U-shaped plate 42, it drives the blower 511 to move to the welding area of the two cylindrical parts. Then, the motor 54 is activated, causing the motor 54 to drive the turntable 55 to rotate. Then, the turntable 55 drives the moving rod 56 to perform a circular motion. Then, while the moving rod 56 slides within the turntable 55, it can drive the rod sleeve 57 to slide on the connecting rod 510, further driving the two rotating plates 59 and the blower 511 to swing around the cross bar 58. The blower 511 is activated, and the blower 511 blows out a protective gas to blow the welding area, forming a stable protective gas layer during welding to prevent the metal from contacting the air and oxidizing during the welding process. When the blower 511 swings, it can synchronously drive the brush bristles 63 to swing, thereby using the brush bristles 63 to brush off the welding slag at the welding area.

[0044] The above has described the embodiments of the invention in detail, but the above content is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention.
