Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more particularly to an ultrasonic welding machine for lower trim panels. Background Technology

[0002] Wheel arches, also known as fenders, are the decorative strips along the upper edge of the tire; they are the semi-circular components that protrude from the fender above the tire. Lower door panels are located primarily below the car doors. Situated at the bottom of the car body, they are close to the road surface during operation, providing excellent protection against water and gravel impacts. Lower door panels are divided into front and rear door panels; wheel arches are also divided into front and rear wheel arches. Traditionally, the front door lower panel and front wheel arch are integrated, as are the rear door lower panel and rear wheel arch. The lower door panel and wheel arches together form the lower trim assembly. Lower trims require welding during production.

[0003] For example, CN208961226U, published on June 11, 2019, discloses an ultrasonic welding equipment for automotive trim panels. This equipment consists of a workpiece placement table, several ultrasonic welding guns, and a pneumatic linear slide. A fixing plate is mounted on the side of the pneumatic linear slide. Several ultrasonic welding guns are arranged in parallel on the side of the fixing plate. An installation angle adjustment block is provided between the fixing plate and each ultrasonic welding gun. The installation angle adjustment block is fixed to the side of the fixing plate with bolts. The aforementioned disclosed device cannot easily adjust the position of the welding guns, thus failing to achieve precise alignment of the welding guns with different welding points on the lower trim panel, resulting in poor practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a more practical ultrasonic welding machine for lower trim panels. This invention allows for convenient adjustment of the position of the welding components on the base via an adjustment mechanism, thereby facilitating the adjustment of the weld point position and enabling precise welding of the lower trim panels, resulting in greater practicality.

[0005] To achieve the above objectives, the technical solution adopted by the present invention to solve its technical problem is: an ultrasonic welding machine for lower trim panels, including a base, a clamping seat for holding the lower trim panel on the base, a welding assembly on the base, a moving assembly for moving the welding assembly on the base, and an adjusting assembly for adjusting the position of the welding assembly on the base.

[0006] The welding assembly includes a transducer and a welding head, the transducer being connected to the welding head and the transducer being connected to a moving assembly.

[0007] The moving component includes a fixed plate connected to the adjusting component, a moving plate provided on the fixed plate, the moving plate being connected to the transducer, and a telescopic cylinder connected to the moving plate provided on the fixed plate.

[0008] The fixed plate is provided with a guide rail, and the guide rail is provided with a slider, which is connected to the movable plate.

[0009] The fixed plate is provided with a first vertical plate, which is connected to the telescopic cylinder. The movable plate is provided with a second vertical plate, which is connected to the transducer. The fixed plate is provided with a limiting block.

[0011] The connecting plate is provided with an arc-shaped hole for bolts to pass through. A first central hole is provided at the center of the arc-shaped hole. The adjusting plate is provided with adjusting holes that are adapted to the position of the arc-shaped hole. The adjusting holes are symmetrically distributed in a ring on the adjusting plate. The adjusting plate is also provided with a second central hole that is adapted to the first central hole.

[0012] The rotary cylinder is provided with a base plate, and a connecting column is provided between the base plate and the base. One end of the connecting column is provided with a first mounting plate, which is connected to the base plate. The other end of the connecting column is provided with a second mounting plate, which is connected to the base.

[0013] The base is provided with a protective frame, the protective frame is provided with a mounting frame, the mounting frame is hinged to a flip frame, the flip frame is provided with a mounting plate, the mounting plate is provided with an abutment block for fixing the lower trim panel, the protective frame is provided with a telescopic rod, the telescopic rod is hinged to the protective frame, the moving end of the telescopic rod is hinged to the flip frame, the protective frame is provided with a support column for supporting the flip frame, and the flip frame is provided with a handle.

The position of the welding component on the base is adjusted by the adjusting component, which makes it easier to adjust the position of the welding point of the welding component, and thus perform precise welding work on the lower trim panel.

[0017] The moving plate is driven by the telescopic cylinder on the fixed plate, and the transducer connected to the moving plate moves to realize the welding work. The stable movement of the moving plate is achieved by the cooperation of the guide rail and the slider.

[0018] By using a rotating cylinder, connecting plate, and adjusting plate, the horizontal and vertical angles of the fixed plate on the base can be adjusted, thereby causing the welding mechanism on the fixed plate to rotate. This allows the welding mechanism to be adjusted to suit welding work at different positions on the lower trim panel, making it more practical. Attached Figure Description

Detailed Implementation

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0029] like Figure 1 As shown, the ultrasonic welding machine for the lower trim panel includes a base 1, a clamping seat 4 for holding the lower trim panel on the base 1, welding components on the base 1, a moving component for moving the welding components on the base 1, and an adjusting component for adjusting the position of the welding components on the base 1. Specifically, the base 1 has five welding components, thereby performing welding work on five positions of the lower trim panel. The clamping seat 4 is adapted to the shape of the lower trim panel.

[0030] In use, the lower trim panel is placed on the clamping seat 4 on the base 1. At this time, the moving component works to move the welding component, thereby performing welding work on the lower trim panel. The position of the welding component on the base is adjusted by the adjusting component, which makes it easy to adjust the position of the welding point of the welding component, thereby performing precise welding work on the lower trim panel.

[0031] The welding assembly includes a transducer 6 and a welding head 7. The transducer 6 is connected to the welding head 7 and the transducer 6 is connected to a moving assembly. The moving assembly operates to move the transducer 6 and the welding head 7. The welding head 7 moves to the lower trim plate on the clamping seat 4 to perform welding work.

[0032] Reference Figure 1-3 The movable component includes a fixed plate 8 connected to the adjustment component, a movable plate 9 on the fixed plate 8, the movable plate 9 being connected to the transducer 6, and a telescopic cylinder 11 connected to the movable plate 9 on the fixed plate 8. The telescopic cylinder 11 operates to move the movable plate 9 on the fixed plate 8, thereby moving the transducer 6 connected to the movable plate 9 to achieve the welding operation.

[0033] Reference Figure 4 The fixed plate 8 is provided with a guide rail 12, and a slider 13 is provided on the guide rail 12. The slider 13 is connected to the movable plate 9. The movement of the movable plate 9 causes the slider 13 to move on the guide rail 12 on the fixed plate 8. The stable movement of the movable plate 9 is achieved through the cooperation of the guide rail 12 and the slider 13. Specifically, the guide rail 12 is provided with two sliders 13, and the two sliders 13 are connected to the movable plate 9 by bolts. The guide rail 12 is connected to the fixed plate 8 by bolts.

[0034] Specifically, the fixed plate 8 is provided with a first vertical plate 10, which is connected to the telescopic cylinder 11. The first vertical plate 10 enables the telescopic cylinder 11 to be stably placed on the fixed plate 8. Specifically, the first vertical plate 10 is welded to the fixed plate 8 and is connected to the telescopic cylinder 11 by bolts. The movable plate 9 is provided with a second vertical plate 14, which is connected to the transducer 6. The second vertical plate 14 enables the installation of the transducer 6 on the movable plate 9. Specifically, the second vertical plate 14 is welded to the movable plate 9 and is connected to the transducer 6 by bolts. The fixed plate 8 is provided with a limiting block 22, which limits the movement of the slider 13 to prevent overtravel. Specifically, the limiting block 22 is connected to the fixed plate 8 by bolts.

[0035] The adjustment assembly includes a rotary cylinder 17, an adjustment plate 16 on the piston of the rotary cylinder 17, and a connecting plate 15 connected to a fixed plate 8. The connecting plate 15 and the adjustment plate 16 are connected by bolts. The rotary cylinder 17 causes the piston to rotate, which in turn causes the adjustment plate 16 to rotate. The rotation of the adjustment plate 16 causes the connecting plate 15 to drive the fixed plate 8 to rotate, thereby causing the welding mechanism on the fixed plate 8 to rotate, thus adjusting the angle of the welding mechanism. Specifically, the adjustment plate 16 is connected to the piston of the rotary cylinder 16 by bolts, and the connecting plate 15 is connected to the fixed plate 8 by bolts. In this embodiment, the connecting plate 15 has an L-shaped cross-section.

[0036] Reference Figure 5 and 6 The connecting plate 15 has an arc-shaped hole 23 for bolts to pass through. A first center hole 24 is located at the center of the arc-shaped hole 23. The adjusting plate 16 has adjusting holes 25 that are adapted to the position of the arc-shaped hole 23. The adjusting holes 25 are symmetrically distributed in a ring on the adjusting plate 16. The adjusting plate 16 also has a second center hole 26 that is adapted to the first center hole 24. When the connecting plate 15 and the adjusting plate 16 are connected, the first center hole 24 and the second center hole 26 are aligned, and the bolt passes through the first center hole 24 and the second center hole 26 for connection. The bolt passes through the adjusting hole 25 and the arc-shaped hole 24. 3. When connecting and adjusting the angle between the connecting plate 15 and the adjusting plate 16, loosen the bolts in the first center hole 24 and the second center hole 26, remove the bolts in the adjusting hole 25 and the arc-shaped hole 23, rotate the connecting plate 15 and the adjusting plate 16 until the fixing plate 8 rotates to the specified angle. At this time, pass the bolts through the adjusting hole 25 and the arc-shaped hole 23 to fix the connecting plate 15 and the adjusting plate 16. Specifically, there are six adjusting holes 25 arranged symmetrically in a ring, and three arc-shaped holes 23 arranged symmetrically in a ring.

[0037] A base plate 18 is provided on the rotary cylinder 17. A connecting column 20 is provided between the base plate 18 and the base 1. A first mounting plate 19 is provided at one end of the connecting column 20 and is connected to the base plate 18. A second mounting plate 21 is provided at the other end of the connecting column 20 and is connected to the base 1. The height of the welding assembly is supported by the first mounting plate 19, the connecting plate 20 and the second mounting plate 21, thereby adapting to the welding point position of the lower trim panel. In this embodiment, the two outermost base plates 18 of the five rotary cylinders 17 are connected to the base 1, while the three middle rotary cylinders 17 are directly connected to the base 1 through the base plates 18. Specifically, the three middle base plates 18 are connected to the base 1 by bolts, the two outermost base plates 18 are connected to the first mounting plate 19 by bolts, and the second mounting plate 21 is connected to the base 1 by bolts.

The protective frame 27 has a telescopic rod 30, which is hinged to the protective frame 27. The moving end of the telescopic rod 30 is hinged to the flip frame 28. The protective frame 27 has a support column 31 for supporting the flip frame 28, and the flip frame 28 has a handle 34. The protective frame 27 protects the welding components and prevents accidental contact by personnel. The flip frame 28 rotates on the mounting frame 29 until the flip frame 28 is aligned with the support column 31. When the support column 31 overlaps, the abutment block 33 on the mounting plate 32 on the flipping frame 28 moves to abut against the lower trim plate on the clamping seat 4, thereby ensuring the fixed work of the lower trim plate and preventing deviation during welding. The telescopic rod 30 facilitates the stable movement of the flipping frame 28. In this embodiment, the telescopic rod 30 is a hydraulic support rod. Specifically, the protective frame 27 is connected to the base 1 by bolts. Two mounting frames 29 and two support columns 31 are welded on the protective frame 27. Two hinge shafts are provided on the flipping frame 28. The two hinge shafts are hinged to the two mounting frames 29. The mounting plate 32 is welded to the flipping frame 28. Five abutment blocks 33 are provided on the mounting plate 32.

[0039] Reference Figure 1 The base 1 is provided with a support frame 2, and the support frame 2 is provided with a support seat 3. The support seat 3 is connected to the clamping seat 4. The clamping seat 4 is installed on the base 1 through the support frame 2 and the support seat 3. Specifically, there are three support seats 3. The three support seats 3 are connected to the clamping seat 4 by bolts. The base 1 is also provided with a bracket 5 to support the end of the clamping seat 4. The bracket 5 supports the extended part of the clamping seat 4, thereby ensuring the stable support of the clamping seat 4 on the base 1.
