Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of automobile manufacturing technology, and in particular, to a welding device for processing a chassis of a new energy pickup truck. Background Art

[0002] In the manufacturing process of new energy pickup trucks, the chassis is the key load-bearing component of the vehicle, and its welding quality is directly related to the safety, stability and overall performance of the vehicle. With the rapid development of the new energy vehicle industry, more stringent requirements are placed on the welding accuracy, efficiency and reliability of the chassis. At present, in the welding process of automobile chassis, in order to ensure the welding quality, the weld needs to be pre-cleaned before welding to remove surface oil, impurities, oxide layer, etc. In the prior art, the cleaning device matched with the welding gun mostly adopts a fixed structure or moves synchronously with the welding gun through an additional drive unit. The cleaning path of these cleaning devices is often pre-set and difficult to change, and cannot be flexibly adjusted according to the complex and changeable shape and weld direction of the chassis of new energy pickup trucks. When facing irregular welds or parts with special curvature on the chassis, the fixed cleaning path makes it impossible to effectively cover some weld areas, resulting in incomplete cleaning. This makes it very easy to cause welding defects such as pores and cracks in some weld areas due to incomplete cleaning in actual operation, and the residual impurities and contaminants during the welding process will seriously affect the strength and reliability of the welded joints. Not only does it reduce the overall quality of the automobile chassis, but it also increases the scrap rate in the production process, increases production costs, and also poses a potential threat to the driving safety of new energy pickup trucks. Summary of the invention In order to overcome the above-mentioned defects, the embodiments of the present disclosure provide a welding device for processing the chassis of a new energy pickup truck, which solves the technical problem in the prior art that the cleaning path of the cleaning device matched with the welding gun on the welding equipment cannot be changed and cannot always fit the chassis to be welded, resulting in incomplete pre-cleaning of the welding point.

DETAILED DESCRIPTION The present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than to limit the present disclosure.

[0017] In order to simplify the drawings, only the parts related to the disclosure are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0018] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this disclosure can be understood according to specific circumstances.

[0019] In the present disclosure, unless otherwise expressly specified and limited, a first feature being “above” or “below” a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being “above”, “above”, and “above” a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0020] In the description of this embodiment, terms such as "up", "down", "left", and "right" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present disclosure.

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] like Figure 1~Figure 2As shown, it shows a welding device in an embodiment of the present disclosure, a rotary support structure is used between the manipulator 8 and the housing 1 to realize rotational connection, so that the housing 1 can be rotated at the end of the manipulator 8 to achieve full angle adjustment, which is convenient for positioning the welding gun 2 and the cleaning device 3. The housing 1 is designed as a frame structure, and a linear guide rail is installed on one side thereof. The sliding frame 31 cooperates with the linear guide rail and can slide linearly along the guide rail.

[0023] The clamping jaw 32 may be a pneumatic clamping jaw, which is mounted on one end of the sliding frame 31 away from the manipulator 8. The pneumatic clamping jaw 32 comprises a cylinder, a piston and four clamping parts 321. The cylinder is fixed on the sliding frame 31. When compressed air is introduced into the cylinder, the four clamping parts 321 are driven to slide linearly toward or away from each other under the action of air pressure, thereby clamping and releasing the cleaning towel 5. The four clamping parts 321 are symmetrically distributed in pairs, and anti-slip stripes are provided on the opposite inner sides. When clamping the cleaning towel 5, the anti-slip stripes can increase the friction between the cleaning towel 5 and the cleaning towel 5, ensuring that the cleaning towel 5 is firmly clamped.

[0024] During operation, the manipulator 8 drives the shell 1 to move to the vicinity of the welding point of the chassis of the new energy pickup truck according to the preset program. Then, the sliding frame 31 slides on the linear guide rail, so that the pneumatic clamp 32 moves to the side away from the manipulator 8 until it is pressed against the chassis. At this time, the cleaning towel 5 contacts the surface of the chassis and begins to clean the impurities and oil stains at the welding point. As the manipulator 8 moves further, the sliding frame 31 continues to slide on the linear guide rail to adapt to the shape change of the chassis, ensuring that the cleaning towel 5 is always tightly fitted with the surface of the chassis, completing the cleaning of the entire area to be welded. After the welding is completed as the manipulator 8 moves, the sliding frame 31 returns to the initial position, stops supplying air to the cylinder, and the piston drives the four clamping parts 321 away from each other, releasing the cleaning towel 5.

[0025] The device uses the rotational connection between the manipulator 8 and the housing 1 and the linear sliding structure of the sliding frame 31 to enable the cleaning device 3 to adapt well to the shape and structure of the chassis of the new energy pickup truck. The clamping claw 32 drives the four clamping parts 321 through air pressure to clamp and release the cleaning towel 5, ensuring the efficient cleaning work. It effectively solves the problem that the weld cleaning device on one side of the automobile chassis welding gun 2 in the prior art cannot always fit the automobile chassis, resulting in incomplete weld pre-cleaning, improves the cleaning effect before welding, and thus improves the welding quality and firmness.

[0026] like Figure 1~Figure 2 As shown, in this embodiment, the elastic member 1 4 is a spring, one end of which is fixed to the housing 1, and the other end is connected to the sliding frame 31. The spring is in a pre-compressed state, providing the sliding frame 31 with a continuous elastic push force toward the chassis.

[0027] During operation, when the manipulator 8 drives the housing 1 close to the chassis, the sliding frame 31 slides on the linear guide rail and presses against the chassis, the elastic member 14 will be further compressed or extended according to the fluctuation of the chassis surface and the change of the pressing force. For example, when encountering a convex part of the chassis surface, the sliding frame 31 is subjected to greater resistance, and the elastic member 14 is further compressed to buffer the pressing force.

[0028] The elastic member 4 works in coordination with the manipulator 8, the sliding frame 31 and the clamping claw 32. The manipulator 8 is responsible for moving the cleaning device 3 to the area to be cleaned, the sliding frame 31 realizes the position adjustment of the cleaning device 3 on the housing 1, and the clamping claw 32 is used to clamp the cleaning towel 5. The elastic pushing effect of the elastic member 4 reduces the reliance on the positioning accuracy of the manipulator 8 and the sliding frame 31 when the cleaning device 3 adapts to the uneven surface of the chassis, and reduces the problem of incomplete cleaning caused by positioning errors.

[0029] like Figure 2~Figure 3 As shown, the swing member 33 is swingably connected to the sliding frame 31 through a pin, and the clamping claw 32 is installed at the outer end of the swing member 33. The towel storage bin 6 is slidably connected to the housing 1 through a guide rail, and the towel storage bin 6 has a towel outlet 61 facing the sliding frame 31.

[0030] When the cleaning towel 5 needs to be replaced, the swing member 33 swings close to the towel outlet 61 under the drive of a power mechanism (such as a gear rack mechanism driven by a small motor), and the towel storage bin 6 slides close to the clamping claw 32 under the drive of another power mechanism (such as an electric push rod). When the clamping claw 32 approaches the cleaning towel 5 at the towel outlet 61, the pneumatic clamping claw 32 moves, and the four clamping parts 321 approach each other, press and clamp the cleaning towel 5. After that, the swing member 33 swings back to the initial position in the opposite direction, ready for cleaning work.

[0031] The cooperation of the swinging member 33, the towel storage bin 6 and the clamping claw 32 realizes the automatic clamping function of the cleaning towel 5. The swinging of the swinging member 33 expands the range of motion of the clamping claw 32, so that the clamping claw 32 can accurately reach the towel outlet 61 of the towel storage bin 6. The sliding function of the towel storage bin 6 ensures that the towel outlet 61 can be close to the clamping claw 32, which is convenient for clamping operation. This structure reduces manual intervention, improves the efficiency of replacing the cleaning towel 5, and thus improves the degree of automation of the entire welding equipment. At the same time, the automatic clamping process reduces the contamination and damage of the cleaning towel 5 during the clamping process, ensures the cleanliness and availability of the cleaning towel 5, and is conducive to improving the cleaning effect.

[0032] like Figure 3~Figure 4 As shown, the sliding frame 31 has an opening 312 facing away from the limiting cavity 311 of the manipulator 8, and a sliding member 34 is arranged in the limiting cavity 311. The sliding member 34 cooperates with the limiting cavity 311 through a guide rail and can slide in the limiting cavity 311. The swing member 33 is swingably arranged at one end of the sliding member 34 away from the manipulator 8.

[0033] Before the cleaning work begins, the sliding member 34 is outside the limiting cavity 311, and the swinging member 33 can swing freely. When the swinging member 33 clamps the cleaning towel 5 and returns to the working position, the sliding member 34 slides along the guide rail of the limiting cavity 311 under the drive of the power mechanism (such as a push rod driven by an electromagnet), driving the swinging member 33 to enter the limiting cavity 311. At this time, the inner wall of the limiting cavity 311 limits the circumferential swing of the swinging member 33, so that the swinging member 33 remains stable during the cleaning process.

[0034] The limiting cavity 311, the sliding member 34 and the swinging member 33 cooperate with each other to improve the stability of the cleaning process. The limiting cavity 311 provides a stable working environment for the swinging member 33, reducing the interference of external factors on the swinging member 33. The sliding function of the sliding member 34 enables the swinging member 33 to switch flexibly between the working and non-working states. During the cleaning process, the stable state of the swinging member 33 ensures the position accuracy of the clamping jaws 32 and the cleaning towel 5, so that the cleaning towel 5 can accurately act on the welding point, improving the cleaning accuracy and effect.

[0035] like Figure 3~Figure 4 As shown, the mounting plate 35 is fixed to one side of the sliding frame 31 , and the telescopic member 36 (such as an electric telescopic rod) is mounted on the mounting plate 35 , and its telescopic direction is perpendicular to the sliding direction of the sliding member 34 .

[0036] When the sliding member 34 slides and drives the swing member 33 to move out of the limiting cavity 311, the telescopic member 36 starts, and its extended end gradually extends and abuts against the side wall of the swing member 33. As the extended end continues to extend, the swing member 33 is pushed to swing around the pin shaft, so that the clamping jaw 32 is adjusted to a suitable angle.

[0037] The telescopic member 36 works in coordination with the sliding member 34, the swinging member 33 and the clamping jaw 32, thus enhancing the adaptability of the device. The sliding of the sliding member 34 enables the swinging member 33 to enter or leave the limiting cavity 311, thus providing a prerequisite for the telescopic member 36 to adjust the angle of the swinging member 33. The telescopic function of the telescopic member 36 can adjust the angle of the swinging member 33 and the clamping jaw 32 according to the different shapes and positions of the chassis welding points. The flexible adjustment of the angle of the clamping jaw 32 enables the cleaning towel 5 to better fit the chassis surface, thus expanding the scope of application of the cleaning device 3 and improving the comprehensiveness and effectiveness of the cleaning. At the same time, this angle adjustment reduces unnecessary cleaning actions and improves the cleaning efficiency.

[0038] like Figure 4~Figure 6 As shown, an abutment plate 37 is installed at the outer end of each clamping portion 321 , and a plurality of anti-slip protrusions 371 are distributed on the outer end surface of the abutment plate 37 .

[0039] When the four clamping parts 321 of the pneumatic clamping jaws 32 approach each other to clamp the cleaning towel 5, the abutment plate 37 first contacts the cleaning towel 5. As the clamping parts 321 continue to approach, the anti-slip protrusions 371 increase the friction with the cleaning towel 5. At the same time, as the four abutment plates 37 gradually approach each other, the cleaning towel 5 is squeezed in the clamping space 322, resulting in wrinkles.

[0040] The abutment plate 37 increases the contact area with the cleaning towel 5, and the anti-skid protrusion 371 further enhances the friction force, ensuring that the cleaning towel 5 does not slide during the clamping process, so that the cleaning towel 5 can more effectively absorb and remove impurities and oil stains at the welding points of the chassis during the cleaning process.

[0041] like Figure 4~Figure 6 As shown, the abutment disc 37 is provided with a bite tooth 372 near one side of the clamping space 322. When the four clamping parts 321 drive the abutment disc 37 to approach each other to clamp the cleaning towel 5, the bite teeth 372 gradually bite each other.

[0042] The bite teeth 372 work together with the abutment plate 37 and the clamping jaws 32 to enhance the clamping stability of the cleaning towel 5. The abutment plate 37 provides a mounting base for the bite teeth 372, and the clamping action of the clamping jaws 32 drives the abutment plate 37 and the bite teeth 372 to approach each other. The mutual bite of the bite teeth 372 further enhances the fixing ability of the cleaning towel 5, ensuring that the cleaning towel 5 is always firmly fixed on the clamping jaws 32 during the entire cleaning process. This reduces the cleaning interruption and incomplete cleaning problems caused by the falling off or displacement of the cleaning towel 5, and improves the continuity and reliability of the cleaning work.

[0043] like Figure 4~Figure 6 As shown, the outer end surface of the abutment disk 37 is provided with an anti-slip hook 373, and the anti-slip hook 373 is adjacent to the anti-slip protrusion 371. When the abutment disk 37 abuts against the cleaning towel 5, the anti-slip hook 373 will be embedded in the fiber of the cleaning towel 5. The abutment disk 37 provides an installation position for the anti-slip hook 373, and the anti-slip protrusion 371 increases the friction between the abutment disk 37 and the cleaning towel 5. The clamping action of the clamping claw 32 makes the abutment disk 37 and the anti-slip hook 373 closely contact the cleaning towel 5. The hooking action of the anti-slip hook 373 further enhances the fixing effect of the cleaning towel 5 and reduces the risk of the cleaning towel 5 falling off. This ensures the continuity and stability of the cleaning work, avoids the operation of re-clamping the cleaning towel 5 due to the falling off of the cleaning towel 5, and improves the work efficiency.

[0044] like Figure 2~Figure 4 As shown, the towel-removing rod 7 is hinged to the side of the towel storage bin 6 away from the manipulator 8 through a pin, and a torsion spring is installed at the hinge of the towel-removing rod 7. The torsion spring is in a pre-stretched state, providing an elastic pulling force for the towel-removing rod 7 to rotate in the direction of the clamp 32.

[0045] When the cleaning work is completed, the four clamping parts 321 of the pneumatic clamping jaws 32 move away from each other, releasing the cleaning towel 5. At this time, the swinging member 33 drives the clamping jaws 32 to swing, and the towel stripping rod 7 rotates close to the clamping jaws 32 under the tension of the torsion spring. When the towel stripping rod 7 passes through the clamping space 322, it will block the cleaning towel 5 and make the cleaning towel 5 separate from the abutment plate 37.

[0046] The towel-removing rod 7, the torsion spring, the swinging member 33 and the clamping claw 32 cooperate with each other to realize the automatic disengagement function of the cleaning towel 5. The swinging member 33 drives the clamping claw 32 to swing, providing an opportunity for the towel-removing rod 7 to contact the cleaning towel 5. The torsion spring provides the power for the towel-removing rod 7 to rotate, so that the towel-removing rod 7 can rotate to a suitable position in time to block the cleaning towel 5. This automatic disengagement function reduces manual intervention and improves the efficiency of replacing the cleaning towel 5. At the same time, it avoids the pollution and damage to the cleaning device that may be caused when the cleaning towel 5 is manually removed, ensuring the cleanliness and reliability of the cleaning device.

[0047] like Figure 2~Figure 4 As shown, the interior of the storage body 62 of the towel storage bin 6 is used to store the cleaning towel 5, and the towel outlet 61 is located on the side of the storage body 62 close to the sliding frame 31. The pressing plate 63 is slidably arranged in the storage body 62 through the guide rail, and the second elastic member 64 (such as a spring) is arranged in the storage body 62, one end of which is connected to the pressing plate 63, and the other end is connected to the inner wall of the storage body 62. The second elastic member 64 is in a pre-compressed state, providing an elastic push force for the pressing plate 63 toward the towel outlet 61.

[0048] When the cleaning towel 5 is stored in the towel storage bin 6, the cleaning towel 5 is placed in the bin body 62, and the pressing plate 63 slides toward the towel outlet 61 under the action of the second elastic member 64, and always presses the cleaning towel 5 toward the towel outlet 61. When the clamping claw 32 approaches the towel outlet 61 to clamp the cleaning towel 5, due to the pushing action of the pressing plate 63, the cleaning towel 5 can be stably located at the towel outlet 61, which is convenient for clamping.

[0049] The warehouse body 62, the pressure plate 63 and the second elastic member 64 work together to ensure the stability of the supply of the cleaning towel 5. The warehouse body 62 provides a storage space for the cleaning towel 5, and the pressure plate 63 exerts a thrust force on the cleaning towel 5 under the action of the second elastic member 64. This structure ensures that no matter how many cleaning towels 5 there are in the warehouse body 62, the cleaning towels 5 can always be near the towel outlet 61, which is convenient for the clamping claw 32 to clamp.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be included in the scope of the claims of the present disclosure.
