Technical Field

[0001] This utility model relates to the field of automotive anti-collision beam processing technology, and in particular to an automatic spraying fixture for processing automotive anti-collision beams. Background Technology

[0002] In the automotive manufacturing industry, crash beams are critical passive safety components, and the quality of their surface coating directly affects their corrosion resistance, aesthetics, and long-term reliability. In particular, modern automotive designs widely employ crash beams with complex curved profiles to balance energy absorption with aesthetic requirements, which places higher demands on their surface coating processes.

[0003] Anti-collision beams often have complex spatial curved surface structures. Traditional fixed spray guns or simple mobile spraying equipment have limited freedom of movement of the nozzle, making it difficult to accurately and continuously adjust the angle and distance of the nozzle relative to the workpiece surface. This leads to problems such as blind spots, excessively thin or thick coatings in areas with large changes in curvature, such as grooves, edges, and large arcs, making it impossible to achieve high-quality uniform coverage of the entire surface.

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figure 1-4 This utility model provides an automatic spraying fixture for processing automotive anti-collision beams, comprising: a workbench 1, a fixing component 2, and a spraying component 3. The workbench 1 forms the basic support platform of the equipment, and at least one slide rail 101 is fixedly installed on its top. The anti-collision beam body 102 to be sprayed is placed and positioned on the top surface of the workbench 1.

[0018] The fixing component 2 is set on the top of the workbench 1 and is used to clamp and fix the anti-collision beam body 102. The fixing component 2 includes a first motor 201. The output shaft of the first motor 201 is fixedly connected to a horizontally arranged first threaded rod 202. Two sections of threads with opposite directions on the first threaded rod 202 are respectively threaded to two clamping blocks 203, so that the two clamping blocks 203 are located on both sides of the anti-collision beam body 102.

[0019] Specifically, when the first motor 201 drives the first threaded rod 202 to rotate, the two clamping blocks 203 can move synchronously towards or away from each other to clamp or release the anti-collision beam body 102. The end of the first threaded rod 202 away from the first motor 201 is rotatably connected to a mounting base fixedly installed on the top of the workbench 1. Two sets of fixing components 2 are symmetrically arranged and work together on the anti-collision beam body 102 to ensure its stability.

[0020] The spraying assembly 3 is used to perform spraying operations. It includes a support frame 301, the bottom of which is slidably connected to a slide rail 101 on the top of the workbench 1, allowing the entire spraying assembly 3 to move horizontally along the slide rail 101. A mounting frame 302 is fixedly connected to the bottom of the support frame 301. A second motor 303 is fixedly mounted on one side of the mounting frame 302. The output shaft of the second motor 303 is fixedly connected to a horizontally arranged second threaded rod 304. A movable block 305 is threaded onto the second threaded rod 304. A guide rod is also fixedly connected inside the mounting frame 302, and the movable block 305 is slidably connected to the guide rod to ensure its movement. It can only move along the curved surface of the main body 102 of the anti-collision beam. The bottom of the movable block 305 is fixedly connected to a mounting plate 306. The top of the mounting plate 306 is fixedly installed with a third motor 307. The output axis of the third motor 307 passes through the through hole opened inside the mounting plate 306 and is fixedly connected to a first gear 308. The first gear 308 is connected to a second gear 310 through a belt 309. A horizontally set rotating disk 311 is fixedly connected to one side of the second gear 310. Multiple nozzles 312 for spraying paint are fixedly installed at the bottom of the rotating disk 311. These nozzles 312 are connected to an external paint supply tank through hoses to obtain paint.

[0021] Specifically, the third motor 307 drives the first gear 308 to rotate, which in turn drives the second gear 310 and the rotating disk 311 to rotate via the belt 309, thereby causing the nozzle 312 to rotate in the horizontal plane. The second motor 303 drives the second threaded rod 304 to rotate, which adjusts the horizontal position of the movable block 305, the mounting plate 306 and the nozzle 312 as a whole. The movement of the support frame 301 along the slide rail 101 realizes the positioning of the nozzle 312 in the longitudinal horizontal direction.

[0022] Working principle: In use, the anti-collision beam body 102 to be sprayed is placed on the top surface of the workbench 1. The first motor 201 of the two sets of fixing components 2 drives the first threaded rod 202 to rotate. Since the threaded rod 202 has two sections of threads with opposite directions of rotation, the two clamping blocks 203 move synchronously towards each other, clamping the anti-collision beam body 102 placed on the top surface of the workbench 1 from both sides, achieving stable positioning. The entire spraying assembly 3 is slidably connected to the slide rail 101 of the workbench 1 through the bottom of the support frame 301, and can move horizontally along the length of the anti-collision beam 102. The second motor 303 drives the second threaded rod 304 to rotate, driving the movable block 305 threaded with it to move laterally horizontally along the guide rod in the mounting frame 302, thereby adjusting the lateral position of the spray head 312 relative to the curved surface of the anti-collision beam 102. Motor 307 drives first gear 308 to rotate, which in turn drives second gear 310 and rotating disk 311 fixed thereon to rotate in the horizontal plane via belt 309. Spray head 312 installed at the bottom of rotating disk 311 rotates accordingly, adjusting the spraying angle. Paint from external paint supply tank is delivered to spray head 312 through hose. By coordinating the longitudinal movement of support frame 301, the lateral movement of movable block 305, and the rotation of rotating disk 311, spray head 312 can be precisely positioned and adjusted to the optimal angle, realizing uniform and automatic spraying operation on the surface of anti-collision beam body 102 with complex curved shape.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
