Description

Technical Field

[0001] This invention relates to the field of suspension bracket welding technology, specifically a welding device for automotive suspension brackets. Background Technology

[0002] In the production and manufacturing of suspension brackets, welding is a key process that connects various metal parts formed by stamping or machining into a complete and rigid structural assembly. Robotic gas shielded welding is usually used, which precisely positions and completes multiple welds at one time on a special fixture. This ensures the geometric dimensions, mounting hole accuracy, and overall strength of the bracket body, enabling it to serve as a sturdy whole and reliably support and fix heavy components in subsequent processes. The welding quality directly determines the load-bearing capacity and durability of the bracket.

[0003] Upon investigation, Chinese Patent Publication No. CN220761511U discloses a welding fixture for an automobile suspension bracket, including a base plate, two longitudinal positioning mechanisms disposed on the base plate and arranged left and right, and a transverse positioning mechanism disposed on the base plate and cooperating with the two longitudinal positioning mechanisms.

[0004] In the above patents, after the suspension bracket is welded on the support beam, it needs to be removed before a new suspension bracket can be placed for the next round of welding. The process of removing and placing the bracket causes the device to stop operating, resulting in non-productive time occupation, thereby reducing the overall welding efficiency of the device.

[0010] As a preferred technical solution of this application, a blocking bracket is fixedly connected to the top of the mounting plate, and a second bracket is fixedly connected to the top of the base, with the top of the second bracket fitting against the bottom of the slide rail.

[0011] As a preferred technical solution of this application, a first bracket is fixedly connected to the top of the base, a motor is fixedly connected inside the first bracket, a mounting seat is fixedly connected to the top of each of the two mounting plates, a rotating shaft is rotatably connected to each of the two mounting seats, and the output end of the motor is fixedly connected to one end of one of the rotating shafts.

[0012] As a preferred technical solution of this application, a connecting block is fixedly connected to one side of both the first working plate and the second working plate, and a first gear is fixedly connected to the side surface of both rotating shafts. A transmission belt is sleeved on both first gears, and the connecting block is fixedly engaged with the transmission belt.

[0013] As a preferred technical solution of this application, the top of the first working plate and the second working plate are both fixedly connected to the mounting frame, the mounting frame is rotatably connected to the stud, and the side surface of the stud is screwed with a fixing clamp, which extends to the outside of the mounting frame and is located at the top of the lifting plate.

[0014] As a preferred technical solution of this application, a rack is fixedly connected to the mounting plate, and two studs penetrate the corresponding first working plate and second working plate. A second gear is fixedly connected to the bottom end of the studs, and the second gear meshes with the rack.

[0015] As a preferred technical solution of this application, a through groove is provided on the first working plate, a push plate is fixedly connected to the bottom of the lifting plate, the push plate extends to the bottom of the first working plate through the through groove, a connecting plate is fixedly connected to one side of the push plate, a spring is fixedly connected to the top of the connecting plate, and the top of the spring is fixedly connected to the bottom of the first working plate.

[0016] As a preferred technical solution of this application, the electric push rod passes through the connecting plate, the bottom of the push plate is provided with an extension section, and the extension section on the push plate passes through the connecting strip.

[0017] As a preferred technical solution of this application, a vertical rod is fixedly connected to the base, two vertical rods are provided, and a baffle is fixedly connected to both vertical rods. The baffle is located on one side of the first working plate and the second working plate.

[0018] The advantages of this invention over the prior art are as follows: 1. By configuring the slide rail, first working plate, second working plate, positioning column, lifting plate, electric push rod, connecting strip, and insertion column, the first and second working plates can move simultaneously. When the first working plate, carrying multiple components that make up the suspension bracket, moves to the welding robot for welding, the second working plate moves away from the welding robot. The operator can then place another set of components that make up the suspension bracket on the second working plate. After the suspension bracket on the first working plate is welded, the second working plate can be moved to the welding robot. At the same time, the first working plate moves away from the welding robot. Subsequently, the operator can remove the welded suspension bracket from the first working plate and place the next set of components that make up the suspension bracket on the lifting plate on the first working plate. This cycle is repeated, effectively improving welding efficiency.

[0019] 2. Through the arrangement of rack, mounting bracket, stud, fixing fixture, and second gear, as the first or second working plate moves multiple components forming the suspension bracket to the welding robot, the second gear rotates due to the influence of the rack, which in turn drives the stud to rotate synchronously. Since the fixing fixture is screwed to the stud, and the mounting bracket limits the fixing fixture, the fixing fixture can move downward along the axis of the stud when the stud rotates. When the first or second working plate moves to the welding robot, the fixing fixture can just press down on some of the components placed on the lifting plate, thereby achieving longitudinal clamping and fixing of the components. This effectively reduces the possibility of longitudinal displacement or shaking of the components during welding and ensures the accuracy of the welding position.

[0020] 3. Through the arrangement of electric push rod, connecting strip, insert post, push plate, connecting plate and spring, the electric push rod can drive the connecting strip to move upward in two stages. When the first stage of the connecting strip moves upward, it can make the insert post move upward and insert into the insertion hole, providing a stable guarantee for the welding work. When the second stage of the connecting strip moves upward, it can push the push plate to move upward. When the push plate moves upward, it can push the lifting plate to move upward along the positioning post, thereby lifting the welded suspension bracket, so that the suspension bracket is detached from the positioning post, making it convenient for the staff to retrieve the suspension bracket.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention provides a welding device for automotive suspension brackets, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes a base 1 and a welding robot 2. The bottom of the welding robot 2 is fixedly connected to the top of the base 1. A support base 3 is fixedly connected to the top of the base 1, and a feeding mechanism is provided on the support base 3.

[0025] The feeding mechanism includes mounting plates 4, and there are two mounting plates 4. The bottom of the mounting plate 4 is fixedly connected to the top of the top support 3. The top of the mounting plate 4 is fixedly connected to the slide rail 5. The top of the slide rail 5 is respectively provided with a first working plate 6 and a second working plate 7. The first working plate 6 and the second working plate 7 are fixedly connected to a connecting piece 34. The bottom of the first working plate 6 and the second working plate 7 are rotatably connected to rollers. The side surface of the rollers is in contact with the inner wall of the slide rail 5. The bottom of the first working plate 6 and the second working plate 7 are both fixedly connected to an electric push rod 10. The movable end of the electric push rod 10 is fixedly connected to a connecting strip 11. The top of the connecting strip 11 is fixedly connected to a pin 12. Both mounting plates 4 are provided with insertion holes 28 that are compatible with the pin 12.

[0026] The top of the first working plate 6 and the second working plate 7 are both fixedly connected with several positioning posts 8, and the top of the first working plate 6 and the second working plate 7 are both movably connected with lifting plates 9, with the positioning posts 8 penetrating through the corresponding lifting plates 9.

[0027] A blocking bracket 29 is fixedly connected to the top of the mounting plate 4, and a second bracket 33 is fixedly connected to the top of the base 1. The top of the second bracket 33 is in contact with the bottom of the slide rail 5.

[0028] The first working plate 6 and the second working plate 7 are arranged in a mirror image of each other. When using this welding device, multiple components that make up the suspension bracket need to be placed on the lifting plate 9 on the first working plate 6, and the positioning pin 8 passes through the mounting hole on the component to limit the component laterally. After placement, the first working plate 6 can be moved so that the first working plate 6 moves multiple components to the welding robot 2 for welding. Since the first working plate 6 is fixedly connected to the second working plate 7 through the connecting piece 34, when the first working plate 6 moves to the welding robot 2, the second working plate 7 will move away from the welding robot 2. At this time, the operator can place another set of components that make up the suspension bracket on the lifting plate 9 on the second working plate 7. After the suspension bracket on the first working plate 6 is welded, the second working plate 7 can be moved to the welding robot 2. At the same time, the first working plate 6 will move away from the welding robot 2. Then, the operator can remove the welded suspension bracket from the first working plate 6 and place the components that make up the suspension bracket on the lifting plate 9 on the first working plate 6. The next set of components on the support frame is placed in a cycle, which effectively improves welding efficiency. In addition, when the first working plate 6 moves to the welding robot 2, the electric push rod 10 at the bottom of the second working plate 7 can be controlled to drive the connecting strip 11 upward, thereby causing the insertion post 12 to move upward and insert into the insertion hole 28, achieving a locking effect on the first working plate 6 and the second working plate 7, making the first working plate 6 and the second working plate 7 unable to move, which can improve the stability of the first working plate 6 and the second working plate 7 during welding. When the second working plate 7 moves to the welding robot 2, the electric push rod 10 at the bottom of the first working plate 6 can be controlled to drive the connecting strip 11 upward, thereby causing the insertion post 12 to move upward and insert into the insertion hole 28. The rollers and slide rails 5 provide the premise for the movement of the first working plate 6 and the second working plate 7, and also provide a guiding effect for the first working plate 6 and the second working plate 7, so that the first working plate 6 and the second working plate 7 can move linearly along the preset trajectory. The second support frame 33 provides a supporting effect for the slide rail 5, improving the stability of the slide rail 5.

[0029] Furthermore, in order to enable the first working plate 6 and the second working plate 7 to move, such as... Figure 1 , Figure 3 and Figure 4 As shown, a first bracket 30 is fixedly connected to the top of the base 1, and a motor 16 is fixedly connected inside the first bracket 30. Mounting seats 13 are fixedly connected to the top of both mounting plates 4, and rotating shafts 14 are rotatably connected to both mounting seats 13. The output end of the motor 16 is fixedly connected to one end of one of the rotating shafts 14.

[0030] A connecting block 18 is fixedly connected to one side of the first working plate 6 and the second working plate 7. A first gear 15 is fixedly connected to the side surface of the two rotating shafts 14. A transmission belt 17 is sleeved on the two first gears 15. The connecting block 18 is fixedly engaged with the transmission belt 17.

[0031] After the motor 16 is started, the output end of the motor 16 will drive the rotating shaft 14 fixedly connected to it to rotate. When the rotating shaft 14 rotates, it will drive the first gear 15 on its side surface to rotate synchronously. Since the transmission belt 17 is sleeved on the two first gears 15, the transmission belt 17 can rotate. When the transmission belt 17 rotates, the connecting block 18 can drive the first working plate 6 and the second working plate 7 to move, thereby realizing the function of the first working plate 6 and the second working plate 7 alternately moving to the welding robot 2 for welding operations. The blocking frame 29 fixedly connected to the top of the mounting plate 4 can limit the movement range of the first working plate 6 and the second working plate 7, reducing the possibility of the first working plate 6 and the second working plate 7 disengaging from the slide rail 5. In addition, an AT42QT series touch sensor can be installed on the blocking frame 29 and connected to the external control terminal together with the motor 16. When the first working plate 6 or the second working plate 7 touches the blocking frame 29, the touch sensor can send a signal to the control terminal, thereby causing the control terminal to control the motor 16 to stop working, which helps to improve the safety of the device operation.

[0032] Furthermore, in order to improve the longitudinal stability of the suspension bracket during welding operations, such as Figure 4 , Figure 5 and Figure 8 As shown, the top of the first working plate 6 and the second working plate 7 are both fixedly connected to the mounting bracket 20. The mounting bracket 20 is rotatably connected to the inside of the mounting bracket 20. The side surface of the mounting bracket 21 is screwed with a fixing clamp 22. The fixing clamp 22 extends to the outside of the mounting bracket 20 and is located on the top of the lifting plate 9.

[0033] A rack 19 is fixedly connected to the mounting plate 4. Two studs 21 pass through the corresponding first working plate 6 and second working plate 7. A second gear 23 is fixedly connected to the bottom end of the studs 21, and the second gear 23 meshes with the rack 19.

[0034] The components mounted on the first working plate 6 and the second working plate 7 are also mirror images of each other. As the first working plate 6 moves the multiple components forming the suspension bracket to the welding robot 2, the second gear 23 rotates due to the influence of the rack 19, which in turn drives the stud 21 to rotate synchronously. Since the fixing clamp 22 is screwed to the stud 21, and the mounting bracket 20 limits the fixing clamp 22, the fixing clamp 22 can move downwards along the axis of the stud 21 when the stud 21 rotates. When the first working plate 6 moves to the welding robot 2, the fixing clamp 22 can just press down on some of the components placed on the lifting plate 9, thus achieving longitudinal clamping of the components. The clamping and fixing effectively reduces the possibility of longitudinal displacement or shaking of parts during the welding process, ensuring the accuracy of the welding position. When the suspension bracket on the first working plate 6 is welded and moves away from the welding robot 2, the second gear 23 will rotate in the opposite direction under the influence of the rack 19, which in turn drives the stud 21 to rotate in the opposite direction, causing the fixing clamp 22 to move upward and reset, releasing the restriction on the welded suspension bracket so that the operator can remove it. Similarly, when the second working plate 7 moves to or away from the welding robot 2, its corresponding fixing clamp 22 will also automatically clamp and release some of the parts that make up the suspension bracket under the same principle, further improving the degree of automation and work efficiency.

[0035] In order to facilitate the removal of the welded suspension bracket by the staff, such as Figure 5 , Figure 6 and Figure 7 As shown, a through groove 27 is provided on the first working plate 6, and a push plate 24 is fixedly connected to the bottom of the lifting plate 9. The push plate 24 extends to the bottom of the first working plate 6 through the through groove 27. A connecting plate 25 is fixedly connected to one side of the push plate 24, and a spring 26 is fixedly connected to the top of the connecting plate 25. The top of the spring 26 is fixedly connected to the bottom of the first working plate 6.

[0036] The electric push rod 10 passes through the connecting plate 25, and the bottom of the push plate 24 is provided with an extension section, which passes through the connecting strip 11.

[0037] When the first working plate 6, carrying the welded suspension bracket, moves away from the welding robot 2, and the second working plate 7, carrying the components of the suspension bracket, moves to the welding robot 2, the electric push rod 10 at the bottom of the first working plate 6 can be activated. This causes the electric push rod 10 to move the connecting bar 11 upward in two stages. When the connecting bar 11 moves upward in the first stage, the insertion post 12 moves upward and inserts into the insertion hole 28, providing a stable guarantee for the welding of the components on the second working plate 7. At the same time, the connecting bar 11 can slide to the top of the extended section of the push plate 24. When the connecting bar 11 moves upward in the second stage, it can push the push plate 24 upward. When the push plate 24 moves upward, it can drive the connecting plate 25 to compress the spring 26, and at the same time, it can push the lifting plate 9 to move upward along the positioning post 8, thereby lifting the welded suspension bracket and causing the suspension bracket to disengage from the positioning post 8, making it convenient for the staff to retrieve the suspension bracket. After the suspension bracket is retracted, the electric push rod 10 can be controlled to drive the connecting strip 11 to move downward and reset. During this period, the spring 26 can push the push plate 24 through the connecting plate 25, so that the push plate 24 moves downward along with the connecting strip 11. At this time, the lifting plate 9 can be reattached to the top of the first working plate 6, so that the staff can place the next set of parts on the lifting plate 9. The insertion post 12 is still inserted in the insertion hole 28. After the suspension bracket on the second working plate 7 is welded, the electric push rod 10 can be driven to drive the connecting strip 11 to move downward and reset for the second time, so that the insertion post 12 moves out of the insertion hole 28, thereby releasing the movement restriction on the first working plate 6 and the second working plate 7. The lifting plate 9, push plate 24, connecting plate 25 and spring 26 on the second working plate 7 are completely consistent with the corresponding structures on the first working plate 6, and their working principle is also the same, so they will not be described in detail here.

[0038] It should be noted that, in order to improve safety during welding work, such as Figure 1 and Figure 2 As shown, two uprights 31 are fixedly connected to the base 1. A baffle 32 is fixedly connected to both uprights 31. The baffle 32 is located on one side of the first working plate 6 and the second working plate 7.

[0039] The baffle 32 can block the spatter generated during the welding process to a certain extent, reducing the potential risks to surrounding equipment or personnel caused by the sparks.

[0040] Working principle: The first working plate 6 and the second working plate 7, along with numerous parts mounted on them, are arranged in a mirror image of each other. When using this welding device, multiple components forming the suspension bracket must be placed on the lifting plate 9 on the first working plate 6, and the positioning pin 8 must pass through the mounting holes on the components. After placement, the motor 16 is started to drive the transmission belt 17 to rotate. When the transmission belt 17 rotates, the connecting block 18 can drive the first working plate 6 and the second working plate 7 to move, thereby enabling the first working plate 6 to move multiple components to the welding robot 2 for welding. During this process, the second gear 23 rotates due to the influence of the rack 19, which in turn drives the stud 21 to rotate synchronously, causing the fixing fixture 2 to rotate. 2. The first working plate 6 can move downwards along the axis of the stud 21. When the first working plate 6 moves to the welding robot 2, the fixing clamp 22 can just press down on some parts placed on the lifting plate 9. After the first working plate 6 moves into place, the second working plate 7 will also move away from the welding robot 2. At this time, the operator can control the electric push rod 10 at the bottom of the second working plate 7 to drive the connecting strip 11 upwards, thereby causing the insert 12 to move upwards and insert into the insertion hole 28, thereby locking the first working plate 6 and the second working plate 7. Another set of parts that make up the suspension bracket can be placed on the lifting plate 9 on the second working plate 7. After the suspension bracket on the first working plate 6 is welded, the electric push rod 10 at the bottom of the second working plate 7 can be controlled to drive the connecting strip 11 upwards. The first working plate 6 moves away from the welding robot 2, and the first working plate 6 moves away from the welding robot 2. Simultaneously, the fixing clamp 22 on the second working plate 7 gradually moves towards and presses against some parts on the second working plate 7. The fixing clamp 22 on the first working plate 6 also moves away from the welding robot 2, and the fixing clamp 22 on the first working plate 6 resets and releases the suspended bracket after welding. After the second working plate 7 moves into position, the electric push rod 10 at the bottom of the first working plate 6 is activated, causing the electric push rod 10 to drive the connecting strip 11 to move upward in two stages. When the connecting strip 11 moves upward in the first stage, the insertion post 12 moves upward and inserts into the insertion hole 28. At the same time, the connecting strip 11 can slide to the top of the extended section on the push plate 24. When the second section moves upward, it pushes the push plate 24 upward. As the push plate 24 moves upward, it compresses the spring 26 via the connecting plate 25, simultaneously pushing the lifting plate 9 upward along the positioning post 8. This lifts the welded suspension bracket, causing it to disengage from the positioning post 8. After the suspension bracket is retracted, the electric push rod 10 can be controlled to move the connecting bar 11 downward for a period of reset. During this time, the spring 26 pushes the push plate 24 via the connecting plate 25, causing the push plate 24 to move downward along with the connecting bar 11. At this point, the lifting plate 9 can reattach to the top of the first working plate 6, allowing the operator to place the next set of parts onto the lifting plate 9. The insertion post 12 remains inserted in the insertion hole 28. After the suspension bracket on the second working plate 7 is welded...This allows the electric push rod 10 to move the connecting strip 11 downwards and reset in the second stage, causing the insertion post 12 to move out of the insertion hole 28. Then, the motor 16 can be controlled again to move the first working plate 6 to the welding robot 2, thus enabling the first working plate 6 and the second working plate 7 to work alternately, effectively improving welding efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
