Description

Technical Field

[0001] This invention belongs to the field of automotive welding technology, specifically a welding and forming tooling for automotive parts. Background Technology

[0002] In modern automotive manufacturing, welding is an indispensable key process for forming body and chassis structural components. Its quality directly affects the safety, reliability and performance of the whole vehicle. Among them, the chassis suspension system is the core of load-bearing and handling, and the manufacturing precision and connection strength of its various components are particularly critical. As one of the most critical load-bearing and guiding components in the suspension system, the welding effect of the automotive control arm will affect the entire suspension system.

[0003] Since automotive control arms are mostly made by splicing and welding a pair of stamped metal plates, tooling is needed to fix them during the welding process. Existing welding tooling mainly includes: worktable, positioning pin, positioning base and pad, etc. Stepped positioning pins or pins are used to achieve precise positioning of parts. The clamping mechanism uses hydraulic cylinders or air cylinders in conjunction with pressure plates and spring pins to apply vertical and horizontal constraints to the parts to ensure that they do not shift during the welding process. Some tooling is also equipped with a rotating mechanism for multi-angle welding.

[0004] The tooling in the above-mentioned technology often needs to be custom-made according to the automotive swing arms to be welded. The positions of the positioning pins, positioning bases and pads used for positioning on the worktable are fixed. As the manufacturer produces fixed products, the fixed tooling will not affect its production. However, as the tooling manufacturer, it needs to re-drill holes on the worktable and move the positions of the positioning pins, positioning bases and pads according to the different automotive swing arms produced by the customer, so as to adapt to different automotive swing arms, thereby increasing the production difficulty and hindering the improvement of production efficiency.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 2As shown in the embodiment of the present invention, a welding and forming fixture for automotive parts includes a workbench 1; a base plate 2 is mounted on the top surface of the workbench 1, and a gap is left between the middle of the workbench 1 and the base plate 2; the surface of the base plate 2 has a plurality of evenly arranged mounting grooves 3; the mounting grooves 3 penetrate the base plate 2 and are arranged in an array; a plurality of support rods 5 are arranged in the mounting grooves 3; screws 6 are rotatably connected to both sides of the base plate 2; a movable plate 7 is threadedly connected between pairs of screws 6; a pair of sliding rods 8 are fixedly connected between pairs of movable plates 7; a base 9 is installed between pairs of sliding rods 8; a support seat 10 is mounted on the top surface of the base 9; the support... A cylinder 11 is rotatably connected to one side of the support 10; a pressure plate 12 is hinged to the telescopic end of the cylinder 11, and the pressure plate 12 is rotatably connected to the support 10; a pressure rod 13 is threadedly connected to the end of the pressure plate 12 away from the cylinder 11; the hinge point between the cylinder 11 and the pressure plate 12 is located at the end of the pressure plate 12 away from the pressure rod 13, while the rotational connection point between the pressure plate 12 and the support is located in the middle of the pressure plate 12, and both the hinge point and the rotational connection point use rolling bearings; during operation, in order to improve the applicability of the automotive swing arm tooling fixture, the embodiment of the present invention can be used. When the user needs to clamp the automotive swing arm, the user needs to first... The car swing arm is placed on the top surface of the base plate 2. The user can then draw a rough outline on the surface of the base plate 2 with chalk. The support rods 5 are then evenly placed into the mounting grooves 3 within the chalk outline. The user then simultaneously rotates the pair of screws 6, causing the moving plate 7 to slide on the top surface of the base plate 2. This, in turn, causes the pair of sliding rods 8 to pass through the chalk outline. The user then slides the base 9, moving the support seat 10 to the edge of the chalk outline. The user then places the car swing arm to be welded on the top surface of the support rod 5. The cylinder 11 is then activated, pushing the pressure plate 12 to rotate, thereby rotating the end of the pressure plate 12. The pressure rod 13 presses against the surface of the car swing arm, and the pressure rod 13 and the support rod 5 work together to clamp the car swing arm. The pair of screws 6 drive the pair of slide rods 8 to move and the base 9 at the pair of slide rods 8 to slide, so that the support seat 10, pressure plate 12, pressure rod 13 and cylinder 11 move to the edge of the car swing arm. Driven by the cylinder 11, they work with the support rod 5 to clamp the car swing arm. This allows users to adjust the position of each component according to their own needs to adapt to different sizes of car swing arms. As a result, production no longer needs to be measured and modified for each customer's needs, thus simplifying the production process and improving production efficiency.

[0023] like Figure 2 , Figure 3 and Figure 8As shown, each pair of sliding rods 8 is provided with a pair of bases 9; each pair of bases 9 is fixedly connected to a connecting block 14 at one end close to the other; each of the two connecting blocks 14 has a slot 15 on its top, and the slot 15 is T-shaped; a pull rod 16 is connected between the two slots 15, and both ends of the pull rod 16 are T-shaped and adapted to the slot 15; electric push rods 17 slide on adjacent sides of the worktable 1, and the telescopic ends of the two electric push rods 17 are fixedly connected to the base 9 closest to their respective sides; during operation, after the side of the car swing arm away from the pressure plate 12 has completed arc welding, the cylinder 11 is started and drives the pressure plate. Rotation 12 causes the pressure rod 13 to move away from the top surface of the car swing arm. At this time, the electric push rod 17 pulls the base 9, causing the support seat 10, pressure plate 12, pressure rod 13 and cylinder 11 on one side of the car swing arm to move away from the car swing arm. Since the pairs of bases 9 are connected by the connecting block 14, the slot 15 and the pull rod 16, the base 9 on the other side of the same pair of slide rods 8 and the support seat 10, pressure plate 12, pressure rod 13 and cylinder 11 on it move to a position where they can clamp the car swing arm. This achieves a change in the clamping direction of the car swing arm. Therefore, the side that was originally blocked by the pressure plate 12 and the pressure rod 13 and could not be welded can be welded normally, thus avoiding the user from clamping and adjusting again.

[0024] like Figures 2 to 4As shown, a rotating column 18 is fixedly connected to one side of the support base 10; a connecting seat 19 is provided on the bottom surface of the support base 10, and the rotating column 18 is rotatably connected to the connecting seat 19; a gear 20 is fixedly connected to one end of the rotating column 18; a toothed plate 21 is meshed with the bottom of the gear 20, and the toothed plate 21 is slidably connected to the connecting seat 19; a gear 22 is meshed with the side of the toothed plate 21 away from the support base 10, and the gear 22 is rotatably connected to the connecting seat 19. The bottom of the second gear 22 is meshed with a second toothed plate 23, and the second toothed plate 23 is slidably connected to the connecting seat 19; a spring 24 is fixedly connected between the second toothed plate 23 and the connecting seat 19; baffles 25 are installed around the perimeter of the worktable 1; during operation, when the electric push rod 17 pulls or pushes one side of the base 9, the base 9 away from the car swing arm will, during its movement, cause the second toothed plate 23 to be squeezed against the baffle 25, and press the second toothed plate 23 into the interior of the connecting seat 19. Simultaneously, the compression spring 24, while the toothed plate 23 moves, drives the meshing gear 22 to rotate. The rotating gear 22 then drives the toothed plate 21 to slide, and the toothed plate 21 in turn drives the gear 20 to rotate, ultimately driving the rotating column 18 to rotate, which in turn drives the support base 10 to rotate 90 degrees. This reduces the obstruction of the support base 10, pressure plate 12, pressure rod 13, and cylinder 11 to the arc welding gun, making it easier to perform arc welding using equipment such as robotic arms. The operation is simpler and no further programming is required to avoid the support seat 10, pressure plate 12, pressure rod 13 and cylinder 11. When the electric push rod 17 drives the base 9 away from the baffle 25, the spring 1 24 returns to its original position, which in turn drives the toothed plate 23 to return to its original position. At this time, the toothed plate 23 will drive the support seat 10 to rotate back to the vertical position through the gear 22, the toothed plate 1 21, the gear 1 20 and the rotating column 18, so that the support seat 10, pressure plate 12, pressure rod 13 and cylinder 11 can properly clamp the car swing arm.

[0025] like Figures 2 to 4 As shown, the bottom surface of the support base 10 has a slot 26; the top surface of the connecting base 19 has a receiving groove 27; a limiting plate 28 is rotatably connected in the receiving groove 27, and the limiting plate 28 is made of high-strength alloy steel; the limiting plate 28 is adapted to the slot 26, and the limiting plate 28 is driven by a servo motor; a proximity sensor is installed on the top surface of the connecting base 19; during operation, when the support base 10 rotates to a vertical position, the proximity sensor on the top surface of the connecting base 19 detects the support base 10 and serves as a trigger signal for the servo motor, causing the servo motor to drive the limiting plate 28 to rotate, so that one end of the limiting plate 28 rotates out of the receiving groove 27 and inserts into the slot 26, thereby restricting the rotation of the support base 10, so that when the pressure plate 12, pressure rod 13 and cylinder 11 on the surface of the support base 10 perform clamping action, the support base 10 can remain stable, avoiding the rotation of the support base 10 from affecting the clamping of the car swing arm.

[0026] like Figures 2 to 5 As shown, a connecting post 29 is fixedly connected to the bottom surface of the support base 10; the diameter of the bottom of the connecting post 29 is larger than the diameter of its top, and the connecting post 29 is made of magnet; the connecting post 29 is rotatably connected to the top surface of the connecting base 19; a rotating groove 30 is formed on the top surface of the connecting base 19 at the corresponding position of the connecting post 29, and the connecting base 19 is made of magnetizable metal; the diameter of the bottom of the rotating groove 30 is smaller than the diameter of its top; a second spring 31 is rotatably connected between the bottom surface of the connecting post 29 and the bottom of the rotating groove 30; during operation, when facing some car swing arms with large bending angles, the user can press down on the support base 10 and the connecting base 19, and compress the second spring 31, so that the connecting post 29 can be connected to the top surface of the connecting base 19. When the side surface of the connecting post 29 on the bottom surface of the connector 19 is no longer in contact with the side surface of the rotating groove 30, and the connecting post 29 is no longer attracted to the inner wall of the rotating groove 30, the connector 19 can rotate normally, thereby driving the support 10, pressure plate 12, pressure rod 13 and cylinder 11 to rotate together, thus adapting to the car swing arm with different bending angles. When adjusted to the appropriate position, the user stops pressing down on the connector 19, the spring 2 31 returns to its original position, and the connector 19 is lifted, so that the side surface of the connecting post 29 is in contact with the inner wall of the rotating groove 30. Thus, the position of the connector 19 is fixed by the friction between the side surface of the connecting post 29 and the inner wall of the rotating groove 30 and the magnetic force between the rotating post 29 and the inner wall of the rotating groove 30.

[0027] like Figures 4 to 5 As shown, the bottom of the rotating groove 30 is provided with a through hole 32; an adjusting rod 33 is provided in the through hole 32; a pressure plate 34 is fixedly connected to the top surface of the adjusting rod 33; a nut 35 is threadedly connected to the bottom of the adjusting rod 33; during operation, when the user needs to press down on the connecting seat 19, the user can screw the nut 35 at the bottom of the adjusting rod 33, thereby causing the adjusting rod 33 to descend, and the pressure plate 34 at the top of the adjusting rod 33 will press the connecting seat 19, thereby driving the connecting seat 19 to descend, thus eliminating the need for the user to continuously provide downward pressure, thereby simplifying the user's operation.

[0028] like Figures 4 to 5 As shown, an annular groove 36 is formed on the top surface of the connecting seat 19 at the position corresponding to the pressure plate 34, and the depth of the annular groove 36 is greater than the radius of the ball bearing 37; a plurality of evenly arranged ball bearings 37 are provided in the annular groove 36; during operation, after the adjusting rod 33 presses down on the connecting seat 19 through the pressure plate 34, when the user rotates the connecting seat 19, the pressure plate 34 rotates relative to the connecting seat 19 through the ball bearings 37 in the annular groove 36, thereby reducing the friction between the two during rotation, thereby reducing wear on both and improving their service life.

[0029] like Figure 1 and Figure 6As shown, a clamping plate 38 is fixedly connected to the bottom surface of the support rod 5, and the clamping plate 38 is adapted to the mounting groove 3; a sleeve 39 is threadedly connected to the support rod 5 near the bottom position; during operation, after the user inserts the clamping plate 38 into the mounting groove 3 at the bottom of the support rod 5, the user needs to lift the support plate and then rotate the support rod 5 90 degrees, so that the clamping plate 38 is perpendicular to the mounting groove 3. At this time, the clamping plate 38 cannot pass through the mounting groove 3. Then the user screws the sleeve 39 onto the surface of the support rod 5. At this time, the sleeve 39 and the clamping plate 38 can cooperate with each other to clamp the support plate, thereby improving the stability of the support rod 5 fixed on the base plate 2.

[0030] like Figure 1 As shown, one end of each pair of screws 6 is fixedly connected to a gear 40; a transmission rod 41 is rotatably connected to the side of the base plate 2 near the pair of gears 40; both ends of the transmission rod 41 are fixedly connected to worm gears 42, and the pair of worm gears 42 are respectively meshed with the pair of gears 40; the middle of the transmission rod 41 is connected to a drive rod 43 through a gear set; during operation, when the user needs to move the plate 7, the user needs to rotate the drive rod 43, and the worm gears 42 at both ends of the drive rod 43 synchronously drive the gears 40 to rotate, and then the two synchronously rotating gears 40 synchronously drive the two screws 6 to rotate, thereby controlling the sliding rod of the moving plate 7 on the surface of the support plate, thereby simplifying the user's operation and improving the usability of the embodiment of the present invention.

[0031] like Figure 1 and Figure 8 As shown, a rotating rod 44 is rotatably connected to the side surface of the workbench 1, and the rotating rod 44 passes through the workbench 1; both ends of the rotating rod 44 are fixedly connected to a worm gear 45; a gear 46 is meshed with the surface of the worm gear; a gear 5 47 is fixedly connected to one side of the gear 46 via a rotating shaft, and both gears 46 and 5 47 are rotatably connected to the workbench 1; a gear 5 47 is meshed with a toothed plate 48; the top of the toothed plate 48 is fixedly connected to the base plate 2, and the toothed plate 48 is slidably connected to the workbench 1; during operation, when the user needs to lift the support... When supporting the plate, the user needs to rotate the rotating rod 44, which drives the worm gears 45 at both ends to rotate. The worm gears 45 then drive the gear 46 to rotate. Since the gear 46 meshes with the toothed plate 48, the two toothed plates 48 will rise under the drive of the gear 46, thereby driving the support plate to rise. Thus, the user does not need to manually lift the support plate. At the same time, the worm gears 45 and the gear 46 are unidirectional transmissions, so the structure also has a self-locking effect, that is, the support plate can maintain the effect of being lifted by the toothed plates 48, further facilitating the user's use.

[0032] In order to improve the applicability of the automotive swing arm tooling fixture during operation, the present invention embodiment can be used. When clamping an automotive swing arm, the user first places the automotive swing arm to be clamped on the top surface of the base plate 2. At this time, the user can draw a rough outline on the surface of the base plate 2 with chalk. Then, the support rod 5 is evenly placed in the mounting groove 3 inside the outline drawn with chalk. Then, the user rotates the pair of screws 6 simultaneously, so that the pair of screws 6 drive the moving plate 7 to slide on the top surface of the base plate 2, thereby driving the pair of sliding rods 8 to pass through the outline drawn with chalk. Then, the user slides the base 9, so that the base 9 drives the support seat 10 to the edge position of the outline drawn with chalk. At this time, the user places the automotive swing arm to be welded on the base plate 2. The top surface of the support rod 5 is then activated by the cylinder 11, which pushes the pressure plate 12 to rotate. This causes the pressure rod 13 at the end of the pressure plate 12 to press against the surface of the car swing arm. Thus, the pressure rod 13 and the support rod 5 work together to clamp the car swing arm. The pair of screws 6 drive the pair of sliding rods 8 to move and the base 9 at the pair of sliding rods 8 to slide, so that the support seat 10, pressure plate 12, pressure rod 13 and cylinder 11 move to the edge of the car swing arm. Driven by the cylinder 11, they work with the support rod 5 to clamp the car swing arm. This allows users to adjust the position of each component according to their needs to adapt to different sizes of car swing arms. As a result, production no longer needs to be based on actual measurements and modifications to the production line for each customer's needs, thus simplifying the production process and improving production efficiency.

[0033] During the arc welding process, after the side of the car swing arm away from the pressure plate 12 has been arc welded, the cylinder 11 is activated and drives the pressure plate 12 to rotate, which in turn drives the pressure rod 13 away from the top surface of the car swing arm. At this time, the electric push rod 17 will pull the base 9, so that the support seat 10, pressure plate 12, pressure rod 13 and cylinder 11 that originally clamped the car swing arm are away from the car swing arm. Since the pairs of bases 9 are connected by the connecting block 14, the slot 15 and the pull rod 16, the base 9 on the other side of the same pair of slide rods 8 and the support seat 10, pressure plate 12, pressure rod 13 and cylinder 11 on it move to a position that can clamp the car swing arm. This achieves a change in the clamping direction of the car swing arm. Therefore, the side that was originally blocked by the pressure plate 12 and the pressure rod 13 and could not be welded can be welded normally, thus avoiding the user from clamping and adjusting again.

[0034] When the electric actuator 17 pulls or pushes one side of the base 9, the base 9 away from the car swing arm will, during its movement, cause the toothed plate 23 to be squeezed against the baffle 25, pressing the toothed plate 23 into the interior of the connecting seat 19, while compressing the spring 24. During the movement of the toothed plate 23, the toothed plate 23 will drive the meshing gear 22 to rotate. The rotating gear 22 will then drive the toothed plate 21 to slide, and the toothed plate 21 will then drive the gear 20 to rotate, ultimately driving the rotating column 18 to rotate, which in turn drives the support seat 10 to rotate 90 degrees, thereby lowering the support seat 10 and the pressure plate 12. The obstruction of the arc welding gun by the pressure rod 13 and the cylinder 11 makes the operation of arc welding using equipment such as robotic arms simpler, eliminating the need for further programming. This allows the support base 10, pressure plate 12, pressure rod 13, and cylinder 11 to be avoided. When the electric push rod 17 moves the base 9 away from the baffle 25, the spring 24 returns to its original position, which in turn moves the toothed plate 23 back to its original position. At this time, the toothed plate 23 will drive the support base 10 to rotate back to the vertical position through the gear 22, toothed plate 21, gear 20, and rotating column 18, so that the support base 10, pressure plate 12, pressure rod 13, and cylinder 11 can properly clamp the car swing arm.

[0035] When the support base 10 rotates to the vertical position, the servo motor drives the limiting plate 28 to rotate, so that one end of the limiting plate 28 rotates out of the receiving groove 27 and inserts into the slot 26, thereby restricting the rotation of the support base 10. This ensures that the support base 10 remains stable when the pressure plate 12, pressure rod 13 and cylinder 11 on the surface of the support base 10 are performing clamping action, and prevents the rotation of the support base 10 from affecting the clamping of the car swing arm.

[0036] When dealing with car swing arms with large bending angles, the user can press down on the support seat 10 and the connecting seat 19, and compress the second spring 31, so that the side surface of the connecting post 29 at the bottom of the connecting seat 19 is no longer in contact with the side surface of the rotating groove 30. At this time, the connecting seat 19 can rotate normally, thereby driving the support seat 10, the pressure plate 12, the pressure rod 13 and the cylinder 11 to rotate together, thus adapting to car swing arms with different bending angles. When adjusted to the appropriate position, the user stops pressing down on the connecting seat 19, the second spring 31 returns to its original position, and the connecting seat 19 is raised, so that the side surface of the connecting post 29 is in contact with the inner wall of the rotating groove 30. Thus, the position of the connecting seat 19 is fixed by the friction between the side surface of the connecting post 29 and the inner wall of the rotating groove.

[0037] When the user needs to press down on the connecting seat 19, the user can turn the nut 35 at the bottom of the adjusting rod 33 to lower the adjusting rod 33, and the pressure plate 34 at the top of the adjusting rod 33 will press the connecting seat 19, thereby driving the connecting seat 19 to lower. This eliminates the need for the user to continuously apply downward pressure, thus simplifying the user's operation.

[0038] After the adjusting rod 33 presses down on the connecting seat 19 through the pressure plate 34, when the user rotates the connecting seat 19, the pressure plate 34 rotates relative to the connecting seat 19 through the ball 37 in the annular groove 36, thereby reducing the friction between the two during rotation, thus reducing wear on both and improving their service life.

[0039] After the user inserts the clamping plate 38 into the mounting slot 3 at the bottom of the support rod 5, the user needs to lift the support plate and then rotate the support rod 5 90 degrees so that the clamping plate 38 is perpendicular to the mounting slot 3. At this time, the clamping plate 38 cannot pass through the mounting slot 3. Then the user screws the sleeve 39 onto the surface of the support rod 5. At this time, the sleeve 39 and the clamping plate 38 can cooperate with each other to hold the support plate, thereby improving the stability of the support rod 5 fixed on the base plate 2.

[0040] When the user needs to move the plate 7, the user needs to rotate the drive rod 43. The worm gear 42 at both ends of the drive rod 43 drives the gear 40 to rotate synchronously. Then, the two synchronously rotating gears 40 drive the two screws 6 to rotate synchronously, thereby controlling the sliding rod of the moving plate 7 on the support plate surface. This simplifies the user's operation and improves the usability of the embodiment of the present invention.

[0041] When the user needs to raise the support plate, the user needs to rotate the rotating rod 44, which drives the worm gears 45 at both ends to rotate. The worm gears 45 then drive the gear 46 to rotate. Since the gear 46 meshes with the toothed plate 48, the two toothed plates 48 will rise under the drive of the gear 46, thereby raising the support plate. Thus, the user does not need to manually raise the support plate. At the same time, the worm gears 45 and the gear 46 are unidirectional, so the structure also has a self-locking effect, that is, the support plate can maintain the effect of being raised by the toothed plate 48, further facilitating the user's use.
