Description

Technical Field

[0001] This invention relates to the field of automotive welding technology, and in particular to a rotary fixture tooling for welding robots in new energy vehicles. Background Technology

[0002] Car seats are a basic component of a vehicle. They mainly consist of seat covers that cover the seat frame. Based on the different materials used for covering the surface, they can be divided into cloth seats, leather seats, and leather seats.

[0003] A search revealed Chinese invention patent CN116713683B, which discloses a rotary fixture tooling device for automotive welding robots. The device includes a welding robot and a fixture tooling section. The fixture tooling section includes a base, the top of which is fixedly connected to the bottom of the welding robot. A drive unit is slidably connected to the base via an electric slide rail on its top. A placement component is fixedly connected to the output end of the drive unit. The placement component includes a hollow block, the outer surface of which is fixedly connected to the output end of the drive unit. This invention relates to the field of automotive welding technology. This rotary fixture tooling device for automotive welding robots effectively solves the problem in the prior art where, during seat armrest welding, conventional flipping fixtures typically have openings on their backs for 180-degree rotation for rear welding. Because parts vary in length and thickness, different models of fixtures are required, making them inconvenient to use.

[0004] Existing welding fixtures typically only support single-part positioning and clamping. When handling multiple parts, repeated disassembly and repositioning are required, which is time-consuming and inefficient. When manually or using simple machinery to connect parts, uneven force application and misalignment of positioning reference can easily lead to misalignment, directly affecting welding quality (such as excessive gaps or misalignment). Furthermore, traditional special-purpose fixtures are mostly "integral structures" customized for specific parts. When changing models, they need to be reprocessed / reassembled, which is costly and time-consuming.

[0005] Therefore, the existing rotary fixture tooling equipment for welding robots of new energy vehicles cannot meet the needs of actual use, so there is an urgent need for improved technology in the market to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a rotary fixture tooling device for welding robots of new energy vehicles, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a rotary fixture tooling device for welding robots of new energy vehicles, comprising a base plate, a placement structure fixedly connected to the middle of the upper surface of the base plate, a drive structure fixedly connected to one side of the upper surface of the base plate located on the placement structure, and a transmission structure rotatably connected to the upper surface of the base plate located on the other side of the placement structure.

[0010] Preferably, the transmission structure includes a first pulley symmetrically rotatably connected to the right end face of the placement plate, a first belt drivingly connecting the two first pulleys, a second pulley symmetrically rotatably connected to the right end face of the placement plate between the two first pulleys, a second belt drivingly connecting the two second pulleys, a rotating shaft on the right end face of the two first threaded rods passing through the placement plate and fixedly connected to the two first pulleys respectively, and the right end face of the two second threaded rods passing through the placement plate and fixedly connected to the two second pulleys respectively.

[0011] Preferably, the sliding structure includes a sliding block 1 slidably connected to the left side of the inner cavity of the placement plate, a through groove 1 is provided on the right end face of the sliding block 1, a threaded rod 1 passes through the sliding block 1 and is threadedly connected, a threaded rod 2 is located in the inner cavity of the through groove 1, and a lower connecting plate 1 is fixedly connected to the upper end face of the sliding block 1.

[0012] Preferably, the second sliding structure includes a second sliding block slidably connected to the right side of the inner cavity of the placement plate. The right end face of the second sliding block has a through groove 2 that penetrates the second sliding block. A first threaded rod is located in the middle of the inner cavity of the second through groove. The second threaded rod penetrates the second sliding block and is threadedly connected. A second lower connecting plate is fixedly connected to the upper end face of the second sliding block. Both the first lower connecting plate and the second lower connecting plate have mounting grooves on their upper end faces that match the connecting structure.

[0013] Preferably, the connection structure includes an upper connecting plate placed in the middle of the upper surface of the lower connecting plate 1 and the lower connecting plate 2 respectively. Each of the four corners of the upper surface of the upper connecting plate is provided with a connecting pin. The connecting pin passes through the lower connecting plate 1 and the lower connecting plate 2 respectively and is threaded. A connecting post is fixedly connected to the middle of the upper surface of the upper connecting plate, and an installation structure is fixedly connected to the upper surface of the connecting post.

[0014] Preferably, the installation structure includes a mounting bracket fixedly connected to the upper end face of the connecting column, and sealing plates are fixedly connected to both the left and right end faces of the mounting bracket. Limiting guide columns with matching clamping structures are evenly fixedly connected between the two sealing plates on both sides.

[0015] Preferably, the clamping structure includes a clamping block slidably connected between two adjacent limiting guide posts. The clamping block has guide grooves on both its front and rear end faces that match the limiting guide posts. An electric telescopic rod is symmetrically fixedly connected between the clamping block and the mounting frame. An electric control module is provided on the outer surface of the mounting frame.

[0016] Preferably, the electric control module includes sub-control modules fixedly connected to the four corners of the mounting frame, a control terminal fixedly connected to the center of the upper surface of the mounting frame, a transmission cable connecting adjacent sub-control modules, the sub-control modules and the control terminal being electrically connected via the transmission cable, and the sub-control modules being electrically connected to the electric telescopic rods that match each of the clamping blocks.

[0017] The present invention has the following beneficial effects: 1. This invention utilizes a placement structure mounted on a base plate to install sliding structure one and sliding structure two during use. Threaded rods one and two adjust their relative positions. A drive structure on the placement structure enables drive motors one and two to rotate in opposite directions via a motor control module, causing threaded rods one and two to rotate synchronously. A transmission structure on the placement structure allows pulleys one and two to form a closed-loop drive via a transmission belt, ensuring that sliding blocks one and two approach each other at the same speed, eliminating mechanical transmission gaps. Furthermore, the sliding structure on the placement structure, through drive motors one and two synchronously controlling the transmission structure, ensures the centered movement of the clamping structures on both sides, achieving high-precision docking of the two parts. Belt drives have buffering and vibration absorption characteristics, reducing mechanical impact and improving motion smoothness. By placing a second sliding structure on the structure, and by setting up a first sliding structure and a second sliding structure separately during use, the clamping structure can be installed independently. Then, the driving structure and transmission structure can achieve independent control of the movement direction and distance of the first sliding structure and the second sliding structure.

[0018] 2. The present invention uses a connecting structure set on sliding structure one and sliding structure two to install the mounting structure during use. Then, by rotating the connecting pin, the lower connecting plate one, the lower connecting plate two and the upper connecting plate are seamlessly fitted and locked, which simplifies the complicated process of traditional bolt fixing and improves assembly efficiency. The modular design allows for quick replacement of connecting plates of different specifications, adapting to diverse parts processing needs. The mounting structure on the connecting structure allows for the installation and placement of the clamping structure during use. Limiting guide posts then limit and fix the movement direction and relative position of the clamping blocks. The clamping structure on the mounting structure ensures that the two clamping structures maintain central symmetry during docking. Even with slight differences in part dimensions, the linear movement of the sliding structure automatically compensates, ensuring uniform gaps at the joints and laying the foundation for high-quality welding. Furthermore, the quick-change structure of the clamping blocks allows for adaptation to various vehicle parts by replacing different specifications of positioning modules. The guide rail spacing between sliding structure one and sliding structure two is adjustable, meeting cross-size processing needs from small sensor brackets to large vehicle frames. The electric control module on the clamping structure communicates with the sub-control module via a bus through the control terminal, ensuring that a single node failure will not cause the entire machine to stop. The transmission cable uses a shielded anti-interference design to adapt to the complex electromagnetic environment of the workshop. All control terminals are centrally located on the operation panel, and the movement status of the electric telescopic rod is displayed in real time via LED indicators, reducing worker learning costs and shortening the training cycle for new employees.

A placement structure 2 is fixedly connected to the middle of the upper end face of the base plate 1. A drive structure 3 is fixedly connected to one side of the upper end face of the base plate 1 located on the placement structure 2. A transmission structure 4 is rotatably connected to the upper end face of the base plate 1 located on the other side of the placement structure 2. A sliding structure 1 5 and a sliding structure 2 6 are symmetrically slidably connected in the inner cavity of the placement structure 2. A connecting structure 7 is installed in the middle of the upper end face of both the sliding structure 1 5 and the sliding structure 2 6.

[0025] Furthermore, the placement structure 2 includes a placement plate 21 fixedly connected to the middle of the upper end face of the base plate 1. The inner cavity of the placement plate 21 is symmetrically connected to a threaded rod 22 along the center line. The inner cavity of the placement plate 21 is symmetrically connected to a threaded rod 23 between the two threaded rods 22. The inner cavity of the placement plate 21 is slidably connected to a sliding structure 5 and a sliding structure 6. Through the placement structure 2 on the base plate 1, the sliding structure 5 and the sliding structure 6 are installed and placed during use, and the relative positions of the sliding structure 5 and the sliding structure 6 are adjusted by the threaded rods 22 and 23 respectively.

[0026] Furthermore, the drive structure 3 includes a drive motor 31 fixedly connected to the upper end face of the base plate 1 at the rear left side of the placement plate 21, a drive motor 32 fixedly connected to the front left side of the placement plate 21, and a motor control module 33 fixedly connected to the upper end face of the base plate 1 between the drive motor 31 and the drive motor 32. The motor control module 33 is electrically connected to the drive motor 31 and the drive motor 32. The output end of the drive motor 31 passes through the placement plate 21 and is fixedly connected to the rear threaded rod 22. The output end of the drive motor 32 passes through the placement plate 21 and is fixedly connected to the rear threaded rod 23. Through the drive structure 3 on the placement structure 2, the drive motor 31 and the drive motor 32 rotate in opposite directions through the motor control module 33 during use, driving the threaded rod 22 and the threaded rod 23 to rotate synchronously.

[0027] Furthermore, the transmission structure 4 includes a pulley 41 symmetrically rotatably connected to the right end face of the placement plate 21, a belt 42 drivingly connected between the two pulleys 41, a pulley 43 symmetrically rotatably connected between the two pulleys 41 on the right end face of the placement plate 21, a belt 44 drivingly connected between the two pulleys 43, a shaft on the right end face of two threaded rods 22 passing through the placement plate 21 and fixedly connected to the two pulleys 41 respectively, and a shaft on the right end face of two threaded rods 23 passing through the placement plate 21 and fixedly connected to the two pulleys 43 respectively. Through the transmission structure 4 on the placement structure 2, in use, the pulleys 41 and 43 form a closed-loop drive through the transmission belt, ensuring that the sliding block 51 and the sliding block 61 approach each other at the same speed, eliminating mechanical transmission gaps.

[0028] Furthermore, the sliding structure 5 includes a sliding block 51 slidably connected to the left side of the inner cavity of the placement plate 21. A through groove 52 is provided on the right end face of the sliding block 51. A threaded rod 22 passes through the sliding block 51 and is threadedly connected. A threaded rod 23 is located inside the through groove 52. A lower connecting plate 53 is fixedly connected to the upper end face of the sliding block 51. Through the sliding structure 5 on the placement structure 2, during use, the drive motors 31 and 32 synchronously control the sliding blocks 51 and 61 in the transmission structure 4, ensuring the centered movement of the clamping structures 9 on both sides and achieving high-precision docking of the two parts. Belt drive has buffering and vibration absorption characteristics, reducing mechanical impact and improving motion stability.

[0029] Furthermore, the sliding structure 26 includes a sliding block 261 slidably connected to the right side of the inner cavity of the placement plate 21. The right end face of the sliding block 261 has a through groove 262 that penetrates the sliding block 261. The threaded rod 22 is located in the middle of the inner cavity of the through groove 262. The threaded rod 23 penetrates the sliding block 261 and is threadedly connected. The upper end face of the sliding block 261 is fixedly connected to a lower connecting plate 263. The upper end faces of both the lower connecting plate 153 and the lower connecting plate 263 have mounting grooves that match the connecting structure 7. Through the sliding structure 26 on the placement structure 2, the clamping structure 9 can be independently installed by setting the sliding structure 15 and the sliding structure 26 respectively during use. Then, the independent control of the moving direction and distance of the sliding structure 15 and the sliding structure 26 can be achieved through the drive structure 3 and the transmission structure 4.

[0030] Furthermore, the connecting structure 7 includes an upper connecting plate 71 placed on the middle of the upper surface of the lower connecting plate 53 and the lower connecting plate 63 respectively. Connecting pins 72 are provided at the four corners of the upper end of the upper connecting plate 71. The connecting pins 72 pass through the lower connecting plate 53 and the lower connecting plate 63 respectively and are threaded together. A connecting post 73 is fixedly connected to the middle of the upper surface of the upper connecting plate 71, and an installation structure 8 is fixedly connected to the upper surface of the connecting post 73. Through the connecting structure 7 on the sliding structure 5 and the sliding structure 6, the installation structure 8 is installed and placed during use. Then, by rotating the connecting pins 72, a seamless fit and locking of the lower connecting plate 53, the lower connecting plate 63, and the upper connecting plate 71 is achieved, simplifying the complex process of traditional bolt fixing and improving assembly efficiency. The modular design supports quick replacement of connecting plates of different specifications, adapting to diverse parts processing needs.

[0031] Furthermore, the installation structure 8 includes a mounting bracket 81 fixedly connected to the upper end face of the connecting column 73. Sealing plates 82 are fixedly connected to both the left and right end faces of the mounting bracket 81. Limiting guide columns 83 that match the clamping structure 9 are evenly fixedly connected between the two sealing plates 82. Through the installation structure 8 on the connecting structure 7, the clamping structure 9 is installed and placed during use, and then the movement direction and relative position of the clamping block 91 are limited and fixed by the limiting guide columns 83.

[0032] Furthermore, the clamping structure 9 includes a clamping block 91 slidably connected between two adjacent limiting guide posts 83. The clamping block 91 has guide grooves on both its front and rear end faces that match the limiting guide posts 83. An electric telescopic rod 92 is symmetrically fixedly connected between the clamping block 91 and the mounting frame 81. An electric control module 93 is provided on the outer surface of the mounting frame 81. Through the clamping structure 9 on the mounting structure 8, the clamping structures 9 on both sides always maintain central symmetry during the docking process. Even if there are slight differences in the size of the parts, they can be automatically compensated by the linear movement of the sliding structure, ensuring uniform gap at the joint and laying the foundation for high-quality welding. Furthermore, since the clamping block 91 adopts a quick-change structure, it can be adapted to various vehicle parts by replacing different specifications of positioning modules. The guide rail spacing between the sliding structure 1 5 and the sliding structure 2 6 is adjustable to meet the cross-size processing needs from small sensor brackets to large vehicle frames.

[0033] Furthermore, the electric control module 93 includes sub-control modules 931 fixedly connected to the four corners of the mounting frame 81. A control terminal 933 is fixedly connected to the center of the upper surface of the mounting frame 81. A transmission cable 932 is connected between adjacent sub-control modules 931. The sub-control modules 931 and the control terminal 933 are electrically connected via the transmission cable 932. The sub-control modules 931 are also electrically connected to the electric telescopic rods 92 that match each clamping block 91. During use, the electric control modules 93 on the clamping structure 9 communicate with the sub-control modules 931 via the control terminal 933 through a bus. A single node failure will not cause the entire machine to stop. The transmission cable 932 uses a shielded anti-interference design to adapt to the complex electromagnetic environment of the workshop. All control terminals 933 are centrally arranged on the operation panel. The operation status of the electric telescopic rods 92 is displayed in real time via LED indicator lights, reducing the learning cost for workers and shortening the training cycle for new employees.

[0034] Working principle: During operation, the upper connecting plate 71 is attached to the lower connecting plate 53 and the lower connecting plate 63 respectively. At this time, the connecting pin 72 is rotated in sequence, so that the upper connecting plate 71 is fixed to the lower connecting plate 63 and the lower connecting plate 53. The parts are placed in the inner cavities of the two mounting structures 8 respectively. At this time, the electric control module 93 is activated, which causes the control terminal 933 to start. The control signal is then transmitted to the sub-control module 931 through the transmission cable 932. As a result, the electric telescopic rod 92 is extended under the control of the sub-control module 931. Therefore, the clamping blocks 91 move closer to each other to clamp the parts. Since the placement structure 2 is provided with sliding structure 1 5 and sliding structure 2 6 respectively, it is possible to position and clamp the two parts at the same time. When the two parts are docked, the drive structure 3 is activated. Through the motor control module 33, the output ends of drive motor 31 and drive motor 32 rotate relative to each other. Therefore, threaded rod 22 and threaded rod 23 rotate relative to each other, which in turn causes pulley 41 and pulley 43 to rotate relative to each other. As a result, sliding block 51 and sliding block 61 move closer to each other, thereby bringing the parts inside the clamping structures 9 on both sides closer to each other. When welding is required, the welding robot 10 is controlled by PLC to weld the seam between the two parts. Since welding is carried out on all four sides of the seam, the welding robot 10's multi-stage adjustment arm is used to achieve welding on all four sides of the seam.
