Description

Technical Field

[0001] This utility model relates to the field of welding alignment fixture technology, specifically a high-precision vehicle frame welding alignment fixture. Background Technology

[0002] Bicycles, also known as pedal bikes or bicycles, are a green and environmentally friendly means of transportation. The bicycle industry is a traditional sector with over 100 years of history. Due to the promotion of green environmental protection and practical problems such as traffic congestion, in recent years, bicycles have once again become a popular means of transportation and fitness for residents of countries around the world, especially developed countries. They have evolved from a traditional mode of transportation to sporty, mountain-riding, and recreational vehicles. The huge annual global demand for bicycles has fueled the enduring prosperity of the bicycle manufacturing industry.

[0003] The bicycle frame is the skeleton of the entire bicycle, and its shape largely determines the correctness and comfort of the riding posture. Therefore, the quality of the assembly and welding of the bicycle frame is crucial.

[0004] In existing technologies, although there are welding clamping structures, the required clamping height varies depending on the different frame components. There is also no height adjustment device, so the height of the frame components cannot be adjusted separately according to the position of the welding point. Furthermore, the existing clamping structures require manual control of the clamping force, which can easily lead to over-clamping.

[0005] Therefore, a high-precision chassis welding alignment fixture is proposed to address the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a high-precision vehicle frame welding alignment fixture, including a mounting base plate. Grooves are formed on both sides of the upper part of the mounting base plate. An electric telescopic rod is positioned at the center of each groove. Driven telescopic rods are positioned on both sides of the electric telescopic rod. A lifting platform is positioned above the electric and driven telescopic rods. A second groove is longitudinally formed at the center of the upper part of the lifting platform. A bidirectional threaded rod is positioned inside the second groove. One end of the bidirectional threaded rod penetrates the mounting base plate and is connected to a rotating motor positioned on the outer surface of the mounting base plate. Threaded sleeve blocks are fitted at the front and rear ends of the bidirectional threaded rod. Grooves are formed on both sides of the mounting base plate. A third groove is formed on each side of the first groove. A sliding rod is positioned inside the third groove. Sliding sleeve blocks are fitted at the front and rear ends of the sliding rod. A moving plate is positioned above the threaded sleeve block and sliding sleeve block on the same side. A mounting sleeve is positioned at the center of the moving plate. The mounting sleeve is connected to an inverted L-shaped mounting plate via adjusting bolts. The inverted L-shaped mounting plate is connected to a clamping plate. There are two clamping plates, one of which has a contact sensor on its inner side.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] This utility model incorporates an electric telescopic rod and a driven telescopic rod. The electric telescopic rods on both sides operate independently. When the electric telescopic rods on both sides extend, they drive the lifting platform to rise. The rise of the lifting platform adjusts the height of the frame, making it easier for the welding points of the two frames to be welded to be aligned.

[0009] This utility model incorporates a rotating motor, a bidirectional threaded rod, a threaded sleeve block, a sliding rod, and a sliding sleeve block. The rotating motor drives the bidirectional threaded rod to rotate, which in turn moves the threaded sleeve block. The movement of the threaded sleeve block moves the moving plate, which in turn moves the clamping structure. As the moving plate moves, the sliding sleeve blocks on both sides below move on the sliding rod, thus improving the stability of the movement.

[0010] This utility model uses an adjusting bolt, a mounting sleeve, and an inverted L-shaped mounting plate. By loosening the adjusting bolt, the length of the inverted L-shaped mounting plate inside the mounting sleeve is adjusted, thereby adjusting the height of the clamping plate, which facilitates clamping the vehicle frame.

[0011] This invention incorporates a contact sensor inside the clamping plate. Once the contact sensor contacts the frame, the rotating motor stops, preventing excessive clamping from damaging the frame. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] As attached Figure 1 , 2 As shown, this utility model provides a high-precision vehicle frame welding alignment fixture, including a mounting base plate 1. Grooves 101 are respectively formed on both sides of the upper part of the mounting base plate 1. An electric telescopic rod 3 is disposed at the center of the groove 101. Driven telescopic rods 4 are respectively disposed on both sides of the electric telescopic rod 3. A lifting platform 5 is disposed above the electric telescopic rod 3 and the driven telescopic rods 4. A second groove 501 is longitudinally formed at the center of the upper part of the lifting platform 5. A bidirectional threaded rod 6 is disposed inside the second groove 501. One end of the bidirectional threaded rod 6 penetrates the mounting base plate 1 and is connected to a rotating motor 17 disposed on the outer surface of the mounting base plate 1. Threaded sleeve blocks 7 are respectively fitted at the front and rear ends of the top of the groove 6. Grooves 3 502 are respectively opened on the mounting base plates 1 on both sides of the groove 101. A sliding rod 8 is provided inside the groove 3 502. Sliding sleeve blocks 9 are respectively fitted at the front and rear ends of the sliding rod 8. A moving plate 10 is provided above the threaded sleeve block 7 and the sliding sleeve block 9 on the same side. An installation sleeve 11 is provided at the center position above the moving plate 10. The upper interior of the installation sleeve 11 is connected to the inverted L-shaped mounting plate 13 through the adjusting bolt 14. The inverted L-shaped mounting plate 13 is connected to the clamping plate 15. There are two clamping plates 15. A contact sensor 18 is provided inside the clamping plate 15.

[0018] Specifically, auxiliary support plates 12 are respectively provided on both sides below the mounting sleeve 11.

[0019] Specifically, a protective pad 151 is provided on the inner side of the clamping plate 15.

[0020] Specifically, the rotating motor 17 is placed on the fixing plate 16 on the outer front surface of the mounting base plate 1.

[0021] Specifically, a control panel 2 is provided on the outer front surface of the mounting base plate 1, and the control panel 2 is electrically connected to the electric telescopic rod 3, the rotating motor 17, and the contact sensor 18.

[0022] Working principle: In use, the two frame components to be welded are placed on the two lifting platforms 5 respectively. The adjusting bolts 14 are loosened, and the length of the inverted L-shaped mounting plate 13 inside the mounting sleeve 11 is adjusted. Then, the height of the clamping plate 15 is adjusted. After adjustment, the rotating motor 17 drives the bidirectional threaded rod 6 to rotate. The rotation of the bidirectional threaded rod 6 drives the threaded sleeve block 7 to move. The movement of the threaded sleeve block 7 drives the moving plate 10 to move. The movement of the moving plate 10 drives the clamping structure to move. When the moving plate 10 moves, the sliding sleeve blocks 9 on both sides below move on the sliding rod 8, which improves the stability of the movement. The two clamping plates 15 move closer to each other to clamp the frame. Since the clamping plate 15 is equipped with a contact sensor 18, the rotating motor 17 stops after the contact sensor 18 contacts the frame to prevent excessive clamping and damage to the frame. Then, the electric telescopic rods 3 on both sides operate independently. The extension of the electric telescopic rods 3 on both sides drives the lifting platform 5 to rise. The rise of the lifting platform 5 adjusts the height of the frame so that the welding points of the two frames to be welded are aligned.
