Description

Technical Field

[0001] This utility model relates to the field of automotive tooling welding technology, specifically an automotive welding fixture. Background Technology

[0002] Automobiles are modern means of transportation, primarily used for carrying people and goods. They typically consist of an engine, chassis, body, and electrical equipment, and are characterized by speed and convenience, finding widespread application in daily life, work, and travel. Welding is a technique that joins metals or other thermoplastic materials together by heating, high temperature, or high pressure. Modern welding utilizes a variety of energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Clamps are required for securing automobiles during welding.

[0003] For example, Chinese Patent Publication No. CN217571540U discloses an automotive welding fixture, including a fixture base. A material groove is formed on the top of the fixture base, and a workpiece positioning steel ring component is assembled and connected to the groove opening. The workpiece positioning steel ring component includes several workpiece columns fixedly connected to the groove opening, each workpiece column having a sliding opening. Positioning steel rings are slidably connected between the workpiece columns. A screw rod, which is slidably connected to the positioning steel ring, is fixedly connected to the sliding opening. The upper end of the screw rod is threadedly connected to a positioning nut. A workpiece side positioning component is assembled and connected to the positioning steel ring. The workpiece side positioning component includes an adjusting screw rod slidably connected to the positioning steel ring, and a workpiece positioning plate is fixedly connected to the inner end of the adjusting screw rod. Two nuts, positioned on both sides of the positioning steel ring, are threadedly connected to the adjusting screw rod. Using the above-mentioned device, the upper and lower parts of large automotive parts can be supported and positioned during the processing of automotive parts.

[0004] After using the automotive welding fixture, it was found that although it can support and position the upper and lower parts of large automotive parts, all its adjusting screws are at the same height, while the fixing points of the automotive parts are not always at the same height. Sometimes it cannot effectively support and position the automotive parts. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1-4This utility model provides a technical solution: an automotive welding fixture, including a base plate 1, which is placed on the ground. A guide rail 101 is fixedly connected to the top of the base plate 1. The guide rail 101 has a circular structure. A slider 2 is slidably mounted on the outer side of the guide rail 101, and the slider 2 can slide on the surface of the guide rail 101. A slide rail 3 is fixedly connected to the top of the slider 2. The upper cross section of the slide rail 3 is "I" shaped. A rack 301 is slidably connected inside the slide rail 3. Each slide rail 3 has two racks 301. A mounting block 302 is fixedly connected to the side of the slide block 301. The mounting block 302 moves together with the rack 301. A screw 303 is threadedly connected to the middle of the mounting block 302. A movable piece 304 is rotatably connected to the end of the screw 303. Rotating the screw 303 allows the movable piece 304 to move horizontally. The movable piece 304 is vertically aligned, fixing the automotive parts from both vertical and horizontal directions. A first bracket 4 is fixedly connected to the top of the slide block 2. There are two first brackets 4 for each slide block 2. The upper part of the first bracket 4 is rotatably connected to... A first bevel gear 402 is connected to the first bracket 4. A rotating rod 401 is fixedly connected to the side of the first bevel gear 402. Rotating the rotating rod 401 causes the first bevel gear 402 to rotate. A worm gear 404 is rotatably connected to the middle of the first bracket 4. The worm gear 404 has a self-locking characteristic. A second bevel gear 403 is fixedly connected to the top of the worm gear 404. Rotating the second bevel gear 403 causes the worm gear 404 to rotate. A second bracket 407 is fixedly connected to the top of the slider 2. A second bracket 407 is rotatably connected to the middle of the second bracket 407. There is a worm gear 405, and a rotating gear 406 is rotatably connected to the middle of the second bracket 407. The worm gear 405 and the rotating gear 406 are fixedly connected. When in use, rotating the rotating rod 401 causes the first bevel gear 402 to rotate, the second bevel gear 403 to rotate, the worm 404 to rotate, the worm gear 405 to rotate, the rotating gear 406 to rotate, the rack 301 to move up and down, the mounting block 302 to move up and down, and the moving piece 304 to move up and down. Rotating the screw 303 can make the moving piece 304 move in the horizontal direction.

[0021] The slider 2 is fixedly connected to a nut 201 on its side. The nut 201 is fixed to the surface of the slider 2. The slider 2 has an opening at the corresponding position. The nut 201 is threaded with a screw 202 in the middle. The opening allows the screw 202 to pass through smoothly. The end of the screw 202 contacts the guide rail 101. Rotating the screw 202 presses the screw 202 against the surface of the guide rail 101, which can fix the slider 2. Loosening the screw 202 allows the slider 2 to be moved to the desired position.

[0022] The movable piece 304 is fixedly connected to a slide rod 305 on its side. The slide rod 305 is slidably connected to the mounting block 302. The slide rod 305 moves with the movable piece 304 and its function is to prevent the movable piece 304 from flipping.

[0023] The first bevel gear 402 meshes with the second bevel gear 403, and the first bevel gear 402 rotates while the second bevel gear 403 rotates.

[0024] In this configuration, the worm 404 and the worm wheel 405 work together, with the worm 404 rotating and the worm wheel 405 rotating.

[0025] In this configuration, the rotating gear 406 meshes with the rack 301, causing the rotating gear 406 to rotate and the rack 301 to move up and down.

[0026] Working principle: When in use, rotating the rotating rod 401 causes the first bevel gear 402 to rotate, the second bevel gear 403 to rotate, the worm gear 404 to rotate, the worm wheel 405 to rotate, the rotating gear 406 to rotate, the rack 301 to move up and down, the mounting block 302 to move up and down, and the moving plate 304 to move up and down. Rotating the screw 303 allows the moving plate 304 to move horizontally.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
