Description

Technical Field

[0001] The present invention relates to the technical field of automotive part welding, and more specifically, to a bolt anti-misalignment welding device for automotive parts. Background Art

[0002] There are many ways to fix automotive parts, and using bolt welding is a common method.

[0003] Regarding welding devices, there are many existing technologies, for example:

[0004] Chinese Patent Publication No. CN219336531U discloses a welding anti-misalignment device for automotive parts, including a magnet seat, a guide frame, a magnet bolt, and a lock. The lock movably penetrates through the magnet seat and is locked with the guide frame. The magnet seat is slidably connected to the front of the guide frame. The magnet bolt is threadedly installed on the guide frame. A pair of magnet seats, magnet bolts, and locks are provided. The guide frame includes a nut, a frame body, and a toothed rod. The nut and the frame body are fixedly connected as a whole. The toothed rods are symmetrically and fixedly connected to the front end of the frame body. The guide frame further includes a limit block. By screwing the magnet bolt to adjust, the magnet bolt spirals along the inside of the guide frame, playing a role in adjusting the drop between the lower end of the magnet bolt and the magnet seat to match the part drop. Opening the lock to adjust the position of the magnet seat on the guide frame to match the part distance. After sucking the two parts of the part tightly with the device, welding is carried out, reducing the welding error rate.

[0005] However, in the actual use process, there are still some problems:

[0006] 1. Currently, in the forging process of traditional automotive parts, if there are multiple groups of evenly arranged welding holes on the surface of the solder plate, operators must frequently manually adjust the position of the solder plate to sequentially complete the welding work of each welding hole. This process not only consumes a large amount of time and energy, but also greatly reduces the overall welding efficiency, making it difficult to meet the needs of large-scale production;

[0007] 2. When welding is completed, the bolt welded at the weld interface position is in the mating limit hole, making the unloading process extremely difficult. Traditional unloading methods often require the assistance of additional tools or consume more manpower, which not only increases the production cost, but may also damage the welded parts due to improper operation, affecting the product quality.

[0008] In view of this, we propose a bolt anti-misalignment welding device for automotive parts. Summary of the Invention

[0017] As a further improvement of the technical solution, the cleaning component includes a column cylinder provided on one side of the substrate.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In the bolt anti-misalignment welding device for automotive parts, by controlling the second cylinder to drive the clamping plate to move horizontally, the diameter of the support roller provided at the end of the clamping plate is adapted to the diameter of the solder plate. The solder plate is placed on the surface of the support roller. Control the output shaft of the rotating motor to drive the belt shaft provided at the end of the support roller to rotate.

[0022] 2. In the bolt anti-misalignment welding device for automotive parts, by moving the pressure roller on the surface of the solder plate, the pressure roller rotates due to friction. When the pressure roller rotates, it drives the first gear to rotate coaxially. When the first gear rotates, it drives the transmission gear rod to engage and rotate. When the transmission gear rod rotates, it drives the second gear to rotate. When the second gear rotates, it drives the eccentric wheel to rotate in contact with the surface of the pressing plate. When the eccentric wheel rotates, it drives the projection welder to reciprocate in the vertical direction.

[0023] 3. In the bolt anti-misalignment welding device for automotive parts, by controlling the moving block to drive the substrate to move horizontally, the cleaning brushes provided on both sides of the substrate are in close contact with the surface of the solder plate.

[0038] 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 of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0039] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, 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 construed as a limitation to the present invention.

[0040] The purpose of this embodiment is to provide an anti-misoperation welding device for bolts of automobile parts. Refer to Figures 1-8 As shown, it includes a chassis 100. A lifting column 101 is provided on the surface of the chassis 100. A welding table 102 is provided on the surface of the lifting column 101. Telescopic rods 200 are provided on both sides of the welding table 102. Clamping plates 201 are provided at the ends of the telescopic rods 200. A second cylinder 202 is provided on one side of the clamping plate 201. The piston rod at the end of the second cylinder 202 is controlled to drive the clamping plate 201 to move relatively to clamp the solder plate. A welding assembly is provided above the solder plate. The welding assembly is used to weld the bolts on the surface of the solder plate. Cleaning assemblies 400 are provided on both sides of the welding assembly. The cleaning assemblies 400 sweep the welding position before welding to remove impurities at the welding position. Feeding assemblies 500 are provided on both sides of the surface of the welding table 102. When the solder plate is welded, the feeding assemblies 500 lift up the solder plate welded with bolts.

[0041] When placing the solder plate, since the solder plate is relatively large in size, it is quite labor-consuming to carry and place it. Therefore, a rotating motor 203 is provided on one side of the clamping plate 201. The rotating motor 203 penetrates through the clamping plate 201 and a support roller 204 is provided at the end. A belt shaft is provided between the support roller 204 and the clamping plate 201. The belt shafts are connected by a transmission belt. The surface of the support roller 204 is used to place the solder plate. When placing the solder plate, the second cylinder 202 is controlled to drive the clamping plate 201 to move horizontally, so that the diameter of the support roller 204 provided at the end of the clamping plate 201 is adapted to the diameter of the solder plate. The solder plate is placed on the surface of the support roller 204. The output shaft of the rotating motor 203 is controlled to drive the belt shaft provided at the end of the support roller 204 to rotate. The belt shaft is driven by the transmission belt, so that the solder plate moves horizontally and is placed above, thereby reducing the labor intensity of the operator.

[0042] When welding bolts, when multiple groups of uniform welding holes are provided on the surface of the solder plate, it is necessary for the operator to continuously adjust the position for welding, resulting in low welding efficiency. Therefore, the welding assembly includes a servo motor 300 provided on one side of the top of the chassis 100. A lead screw 301 is provided at the output end of the servo motor 300. A moving block 302 is provided on the surface of the lead screw 301. A substrate 303 is provided below the moving block 302. A projection welder 304 is provided at the bottom of the substrate 303. The projection welder 304 is used to weld the bolts placed on the surface of the solder plate. A pressure plate 305 is provided at the top of the projection welder 304. A return spring 306 is provided between the pressure plate 305 and the substrate 303. By pressing the pressure plate 305, the projection welder 304 is driven to move downward in the vertical direction to the bolt welding position. During welding, the output end of the servo motor 300 is controlled to drive the lead screw 301 to rotate. When the lead screw 301 rotates, the moving block 302 moves horizontally. When the moving block 302 moves, it drives the substrate 303 to move horizontally. When the projection welder 304 moves above the welding hole, the return spring 306 is squeezed by pressing the pressure plate 305, so that the projection welder 304 provided at the bottom of the pressure plate 305 moves to the surface of the bolt placed at the welding hole, and welding operations are performed through the projection welder 304, so that the projection welder 304 provided below the substrate 303 can quickly weld the welding holes uniformly provided on the surface of the solder plate, improving the welding efficiency.

[0043] The working principle of the projection welder 304 is as follows: Projection point setting: Process a projection point structure corresponding to the bolt on the surface of the solder plate to be welded, or use an auxiliary device such as a fixture with projection points to achieve the projection welding function.

[0044] Workpiece clamping and positioning: Place the bolt accurately between the electrodes of the projection welder 304, and make the projection part of the bolt closely fit and align with the surface of the solder plate to be welded. Fix the bolt and the base material through a fixture or a positioning device to ensure that their relative positions remain unchanged during the welding process, so as to ensure the stability and consistency of the welding quality.

[0045] Applying pressure: The projection welder 304 applies a certain pressure to the bolt and the base material through a hydraulic pressure mechanism. This pressure makes the projection of the bolt closely contact the surface of the base material, reducing the contact resistance, creating good conditions for the current to pass through, and also helping the melted metal to better fuse and diffuse during welding, and ensuring the tightness of the connection during the cooling and solidification process.

[0046] Power-on heating: When the electrode is in good contact with the workpiece and pressure is applied, the welding power supply provides current to the electrode. When the current passes through the bolt, the projection point, and the solder plate, due to the relatively large resistance at the projection point, according to Joule's law, the current will concentrate at the projection point and generate a large amount of heat, causing the metal on the surface of the projection point and the bolt and the base material in contact with it to quickly heat up to the melting state, forming a fusion nucleus.

[0047] Nugget Expansion and Metal Fusion: Under the continuous action of current and pressure, the metal at the bump continuously melts, and the nugget gradually expands. The metal of the bolt and the solder plate fuse with each other to form a continuous liquid metal region, realizing the connection between the two.

[0048] Cooling and Solidification and Formation of Solder Joints: After reaching the predetermined welding time, the welding power supply cuts off the current and stops providing heat. At the same time, the electrodes continue to maintain pressure, causing the melted metal to cool and solidify under pressure. During the cooling process, the metal atoms are rearranged to form strong metal bonds, forming one or more firm solder joints between the bolt and the base material, thus completing the welding connection between the bolt and the base material.

[0049] Release Pressure and Remove Workpiece: After cooling is completed, the pressurizing mechanism releases the electrodes and relieves the pressure on the workpiece, and then removes the welded workpiece with the bolt from the projection welder 304, completing the entire welding process.

[0050] When the solder plate is placed on the surface of the support roller 204, when the surface of the solder plate is relatively thin, its surface strength is poor, and it is easy to cause the solder plate to shake when the projection welder 304 presses down. When the solder plate shakes, the bolts placed at the welding interface are misaligned, resulting in the deviation of the welding position and affecting the subsequent processing and use. Therefore, pressure rollers 307 are provided on both sides of the bottom of the substrate 303. When the pressure rollers 307 move, they fit the surface of the solder plate. When the projection welder 304 welds the solder plate, the pressure rollers 307 press both sides of the welding position to keep the solder plate stable. First gears 308 are provided on the sides of the pressure rollers 307. When the substrate 303 drives the projection welder 304 to move horizontally to weld the bolts, the bottoms of the pressure rollers 307 fit the surface of the solder plate and move. During the rolling process, the pressure rollers 307 press both sides of the welding interface position. At the same time, when the projection welder 304 welds multiple welding holes, the pressure rollers 307 keep the welding position of the solder plate stable, thus avoiding the deviation of the welding position during bolt welding and improving the yield rate during the bolt welding process.

[0051] Considering that during the welding process of multiple bolts, when the pressure roller 307 moves to the welding position, it is necessary to press the pressure plate 305 to drive the projection welder 304 to move downward in the vertical direction to weld the bolt positions, which is rather troublesome. Therefore, an eccentric wheel 310 is provided above the pressure plate 305. When the eccentric wheel 310 rotates, it presses the surface of the pressure plate 305, and the pressure plate 305 drives the projection welder 304 to move downward in the vertical direction. Second gears 311 are provided on both sides of the eccentric wheel 310, and a transmission gear rod 309 is provided on one side of the second gears 311. The bottom of the transmission gear rod 309 is in tooth engagement with the tooth pattern of the first gear 308. During the welding process, the pressure roller 307 moves on the surface of the solder plate, and the pressure roller 307 rotates due to the frictional force. When the pressure roller 307 rotates, it drives the first gear 308 to rotate coaxially. When the first gear 308 rotates, it drives the transmission gear rod 309 to rotate meshingly. When the transmission gear rod 309 rotates, it drives the second gears 311 to rotate. When the second gears 311 rotate, they drive the eccentric wheel 310 to rotate in contact with the surface of the pressure plate 305. When the eccentric wheel 310 rotates, it drives the projection welder 304 to reciprocate in the vertical direction. Among them, the distance between adjacent positions of the bolt weld interface is the same as the circumference of the pressure roller 307, so as to ensure that when moving to the adjacent weld interface position during the welding process, the weld interface can be automatically and accurately welded.

[0052] During welding, when the welding plate moves on the surface of the support roller 204, in order to quickly position it, therefore, a first cylinder 104 is provided on the back of the chassis 100. A baffle 103 is provided at the end of the piston rod of the first cylinder 104. A groove is provided on the surface of the baffle 103, and a fan 105 is provided in the groove. Control the piston rod at the end of the first cylinder 104 to drive the baffle 103 to move horizontally to the set position. The side wall of the solder plate moving on the surface of the projection welder 304 is limited by the baffle 103. When the side wall of the solder plate is completely attached to the surface of the baffle 103, control the piston rod at the end of the second cylinder 202 to push the clamping plate 201 to squeeze and fix both sides of the solder plate, so as to quickly limit and fix the solder plate. When the solder plate is fixed, blow air on the surface of the solder plate through the fan 105, so that the solder plate during the welding process can be quickly cooled, avoiding scalding of personnel caused by too high temperature on the surface of the solder plate after welding and avoiding potential safety hazards. At the same time, cooperate with the cleaning assembly 400 through the fan 105 to blow away the impurities on the surface of the solder plate, avoiding false soldering at the weld interface, thereby improving the welding quality.

[0053] When there are impurities near the welding interface, it is easy to cause false soldering at the welding point, affecting the welding strength. Therefore, the cleaning component 400 includes a cylinder 401 provided on one side of the substrate 303. A slide bar 402 is slidably provided on the inner wall of the cylinder 401. A compression spring 403 is provided between the cylinder 401 and the slide bar 402. A cleaning brush 404 is provided at the bottom of the slide bar 402. In the natural state, the height of the cleaning brush 404 is lower than that of the projection welder 304. A support frame is provided on the top of the substrate 303. A first motor 405 is provided on one side of the support frame. A winding roller 406 is provided at the output end of the first motor 405. A pull rope 407 is wound on the surface of the winding roller 406. The free end of the pull rope 407 is fixed to the top of the slide bar 402. When the solder plate is welded, the substrate 303 is driven to move horizontally by controlling the moving block 302. The cleaning brushes 404 provided on both sides of the substrate 303 are in close contact with the surface of the solder plate. The cleaning brushes 404 reciprocally sweep the welding interface during the movement, and cooperate with the blowing of the fan 105, so as to blow away the dust and impurities at the welding interface, improving the welding strength of the bolts. When the impurity cleaning is completed, the output shaft of the first motor 405 is controlled to drive the winding roller 406 to rotate, so that the pull rope 407 is wound on the surface of the winding roller 406. During the stretching process of the winding roller 406, the slide bar 402 is driven to move upward along the inner wall of the cylinder 401, thus preventing the cleaning brush 404 from deforming due to high temperature during the welding process.

[0054] When the welding is completed, since the bolts welded at the welding interface are in the limit holes, it is inconvenient to unload the materials. Therefore, the above-mentioned blanking component 500 includes support plates 501 provided on both sides of the surface of the welding table 102. The support plates 501 are used to support the solder plate. A moving rod 502 is provided at the bottom of the support plate 501. The moving rod 502 slides on the surface of the welding table 102. An elastic member 503 is provided between the moving rod 502 and the welding table 102. When the solder plate is welded, the lifting column 101 is controlled to drive the welding table 102 to move downward. When the welding table 102 moves downward, the moving rod 502 is in contact with the surface of the chassis 100. When the welding table 102 continues to move downward, the moving rod 502 squeezes the elastic member 503, so that the support plate 501 jacks up the bottom of the solder plate placed on the surface of the support roller 204, thus facilitating the operator to unload the welded solder plate.

[0055] During specific use, the second cylinder 202 is controlled to drive the clamping plate 201 to move horizontally, so that the diameter of the support roller 204 provided at the end of the clamping plate 201 is adapted to the diameter of the solder plate. The solder plate is placed on the surface of the support roller 204. The output shaft of the rotating motor 203 is controlled to drive the belt shaft provided at the end of the support roller 204 to rotate. The belt shaft is driven by a transmission belt, so that the solder plate moves horizontally and is placed above, thereby reducing the labor intensity of the operator;

[0056] When the substrate 303 drives the projection welder 304 to move horizontally for welding the bolts, the bottom of the pressure roller 307 fits and moves along the surface of the solder plate. During the rolling process of the pressure roller 307, it presses on both sides of the weld joint position. At the same time, when the projection welder 304 welds multiple welding hole positions, the pressure roller 307 keeps the welding position of the solder plate stable, thus avoiding the offset of the welding position during bolt welding and improving the yield rate during the bolt welding process. The pressure roller 307 moves on the surface of the solder plate, and the pressure roller 307 rotates due to the frictional force. When the pressure roller 307 rotates, it drives the first gear 308 to rotate coaxially. When the first gear 308 rotates, it drives the transmission gear rod 309 to engage and rotate. When the transmission gear rod 309 rotates, it drives the second gear 311 to rotate. When the second gear 311 rotates, it drives the eccentric wheel 310 to rotate in contact with the surface of the pressing plate 305. When the eccentric wheel 310 rotates, it drives the projection welder 304 to reciprocate in the vertical direction. Among them, the distance between adjacent positions of the bolt weld joint is the same as the circumference of the pressure roller 307, so as to ensure that it moves to the adjacent weld joint position during the welding process, and thus can automatically and accurately weld the weld joint;

[0057] When the welding of the solder plate is completed, the substrate 303 is driven to move horizontally by controlling the moving block 302. The cleaning brushes 404 provided on both sides of the substrate 303 are in close contact with the surface of the solder plate. During the movement, the cleaning brushes 404 reciprocally sweep the weld joint, and cooperate with the blowing of the fan 105, so as to blow away the dust and impurities at the weld joint and improve the bolt welding strength. When the welding of the solder plate is completed, the lifting column 101 is controlled to drive the welding table 102 to move downward. When the welding table 102 moves downward, the moving rod 502 is in contact with the surface of the chassis 100. When the welding table 102 continues to move downward, the moving rod 502 presses on the elastic member 503, so that the support plate 501 jacks up the bottom of the solder plate placed on the surface of the support roller 204, thus facilitating the operator to unload the welded solder plate.
