[0002] Automotive nut plates are extremely important components in the automotive parts system. They are mainly used to provide connection and fixing points, and together with bolts, they are used to firmly install various automotive parts onto the car body and frame. They are key parts to ensure the stable assembly of various automotive components. Welding equipment is the equipment used to perform welding processes. Through heating and pressurization, automotive nut plates are permanently connected to the car body and other related components.

[0003] In the automotive manufacturing industry, the purpose of automotive nut plate welding equipment is to precisely and firmly weld nut plates to designated positions on the car body and frame to meet the needs of component connection during the car assembly process and ensure the stability and reliability of the overall car structure. In the existing automotive production process, welding operations are performed through simple mechanical positioning and fixing. However, the existing welding method has drawbacks. For example, the slag collection structure is just a simple tray. After the slag falls in, it tends to accumulate on the edge of the tray and sticks over time. Cleaning requires tools to pick it out bit by bit, which affects the overall production quality and progress of the car and cannot meet the growing requirements of the automotive manufacturing industry for efficient and high-quality production. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a welding device for automotive nut plates, which aims to improve the existing technology where the slag collection structure is just a simple tray, and the slag easily accumulates on the edge of the tray after falling in, and will stick over time, requiring tools to pick it off bit by bit during cleaning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a welding device for automotive nut plates, comprising a support box, a stepper motor fixedly connected to the top of the support box, a first bevel gear fixedly connected to the output end of the stepper motor, a second bevel gear meshing with the inner wall of the first bevel gear, a connecting rod fixedly connected to the inner wall of the second bevel gear, a plurality of transmission gears rotatably connected to the top of the connecting rod, a fixed plate rotatably connected between adjacent transmission gears, a connecting plate rotatably connected to the bottom of the plurality of fixed plates, a scraper fixedly connected to the bottom of the connecting plate, slide rails fixedly connected to the front side of the support box, rollers slidably connected between adjacent slide rails, a scraper fixedly connected to the front side of the rollers, a waste residue box slidably connected to the bottom of the scraper, and a clamping mechanism fixedly connected to the front side of the support box for clamping.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see the appendix Figure 1 and attached Figure 4 This utility model provides an embodiment of a welding device for automotive nut plates, comprising a support box 1, a drive motor 3 fixedly connected to the top of the support box 1, a first bevel gear 4 fixedly connected to the output end of the drive motor 3, a second bevel gear 5 meshing with the inner wall of the first bevel gear 4, a connecting rod 6 fixedly connected to the inner wall of the second bevel gear 5, a plurality of transmission gears 7 rotatably connected to the top of the connecting rod 6, a fixing plate 8 rotatably connected between adjacent transmission gears 7, a connecting plate 9 rotatably connected to the bottom of the plurality of fixing plates 8, a scraper 12 fixedly connected to the bottom of the connecting plate 9, a slide rail 10 fixedly connected to the front side of the support box 1, a roller 11 slidably connected between adjacent slide rails 10, a scraper 12 fixedly connected to the front side of the roller 11, a waste slag box 13 slidably connected to the bottom of the scraper 12, and a clamping mechanism 2 fixedly connected to the front side of the support box 1 for clamping. Specifically, the stepper motor 3 at the top of the support box 1 serves as the power source, and its output drives the first bevel gear 4 to rotate. The first bevel gear 4 meshes with the inner wall of the second bevel gear 5, converting the horizontal rotation into a vertical rotation, driving the connecting rod 6 to rotate. Multiple transmission gears 7 at the top of the connecting rod 6 cooperate with each other, and each transmission gear 7 is connected to the connecting plate 9 through the fixing plate 8, ultimately driving the scraper 12 at the bottom to perform a circular motion. The scraper 12 slides on the slide rail 10 on the front side of the support box 1 through the roller 11, achieving stable horizontal movement. The scraper 12 is in close contact with the waste slag box 13 at the bottom. During its circular motion, it scrapes the welding waste slag into the waste slag box 13 in a timely manner, keeping the working area clean. The clamping mechanism 2 on the front side of the support box 1 is responsible for fixing the automotive nut plate to be welded, ensuring the precise position of the workpiece during the welding process and avoiding displacement that affects the welding quality. After the drive motor 3 is started, the power is transmitted sequentially through the first bevel gear 4, the second bevel gear 5, and the connecting rod 6 to the transmission gear set 7, driving the scraper 12 to perform both circular and horizontal movements simultaneously, efficiently cleaning the waste slag. The clamping mechanism 2 simultaneously fixes the workpiece, providing a stable environment for the welding operation.

[0019] Please see the appendix Figure 2 and attached Figure 5The clamping mechanism 2 includes a limiting block 201, the rear side of which is fixedly connected to the front side of the support box 1. The inner wall of the limiting block 201 is provided with multiple sliding grooves 202 and multiple limiting slots 203. The inner wall of the sliding grooves 202 is slidably connected to a slider 204. The outer wall of the slider 204 is fixedly connected to a fixed connecting rod 205. The outer wall of the fixed connecting rod 205 is slidably connected to a limiting connecting rod 206. Each of the multiple limiting connecting rods 206 is fixedly connected to a connecting rod 207. The outer wall of the connecting rod 207 is fixedly connected to a driven bevel gear 208. The inner wall of the driven bevel gear 208 is meshed with a driving bevel gear 209. The top of the support box 1 is fixedly connected to a drive motor 210. The output end of the drive motor 210 is fixedly connected to the inner wall of the driving bevel gear 209. Specifically, the limiting block 201 is fixed to the support box 1, and its inner wall is provided with a sliding groove 202 and a limiting groove 203 to provide a motion track and limiting space for components such as the slider 204. The drive motor 210 starts, and the output end drives the drive bevel gear 209 to rotate. Since the drive bevel gear 209 meshes with the driven bevel gear 208, it can transmit power to the driven bevel gear 208, causing it to rotate in linkage. The driven bevel gear 208 is fixed to the outer wall of the connecting rod 207. As the driven bevel gear 208 rotates, the connecting rod 207 drives the limiting connecting rod 206 and the fixed connecting rod 205 to move, thereby pushing the slider 204 to slide in the sliding groove 202. Through the cooperation of multiple sets of connecting rods, forces are applied to the nut plate from different directions. With the limiting groove 203 limiting, the nut plate is stably clamped, ensuring accurate positioning during welding and avoiding deviation that affects the welding quality.

[0020] Please see the appendix Figure 1 and attached Figure 2 A controller 14 is fixedly connected to the left side of the support box 1. The controller 14 is electrically connected to the stepper motor 3 and the drive motor 210 respectively. A tripod 15 is fixedly connected to the inner wall of the support box 1. Multiple support rods 16 are fixedly connected to the bottom of the support box 1. Multiple sliders 204 are slidably connected to screw plates 17. The outer wall of the fixed connecting rod 205 is slidably connected to the inner wall of the limiting groove 203. Specifically, the controller 14, through electrical connection, precisely controls the start, stop, and operation of the stepper motor 3 and the drive motor 210, ensuring stable power transmission of the device. The tripod 15 enhances the structural strength of the support box 1, and the support rod 16 provides stable support for the entire structure. The slider 204, in conjunction with the fixed connecting rod 205, slides in the limiting groove 203 to achieve precise clamping and positioning of the screw plate 17.

[0021] Please see the appendix Figure 2 and attached Figure 3The top of the support box 1 is fixedly connected to multiple fixed rods 18, the top of the fixed rods 18 is fixedly connected to an electrical box 19, the top of the electrical box 19 is fixedly connected to a rotating shaft 20, the top of the rotating shaft 20 is fixedly connected to a fixed rotating rod 21, the inner wall of the fixed rotating rod 21 is rotatably connected to a rotating rod 22, and the inner wall of the rotating rod 22 is rotatably connected to a welding head 23. Specifically, the fixing rod 18 on the top of the supporting box 1 is used to fix the electrical box 19, which provides power support for welding. The rotating shaft 20 can drive the fixed rotating rod 21 to rotate, and the rotating rod 22 on the fixed rotating rod 21 can flexibly adjust the angle, thereby driving the welding head 23 to move, realizing the welding of nut plates at different positions and meeting diverse welding needs.

[0022] Working principle: First, based on the support box 1, the stepper motor 3 provides power to drive the first bevel gear 4 and the second bevel gear 5 meshing with it to rotate, which in turn drives the connecting rod 6 fixed to the second bevel gear 5, and then drives the transmission gear 7 rotatably connected to the connecting rod 6. Under the action of the fixed plate 8, multiple transmission gears 7 mesh and connect, thereby driving the connecting plate 9 on it. Then, using the slide rail 10 on the support box 1 and the roller 11 fixed to the scraper 12, the scraper 12 is moved horizontally to clean the welding slag in its waste slag box 13, reducing manual operation, lowering the cost of use, and improving the efficiency of use. First, based on the model of the screw plate 17, and using the limiting block 201 as a base, the drive motor 210 is used as the power source to drive the drive bevel gear 209 and the driven bevel gear 208 to rotate, thereby driving the connecting rod 207 on it. Then, using the limiting connecting rod 206 and the connecting rod 207 connected to it on both sides, the slider 204 is moved. Then, under the restriction of the slide groove 202 and the limiting groove 203, the slider 204 is made to perform translational movement, which reduces the cost of use and improves practicality.
