Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically a dust removal device for automotive parts processing. Background Technology

[0002] Automobiles are composed of multiple parts during the manufacturing process, such as engines, chassis, bodies, and various electrical components. Each part needs to be manufactured separately and then assembled.

[0003] During the production and processing of brake discs, in order to ensure product quality and facilitate assembly, workers need to polish and repair the details of the parts, such as burrs on the edges and corners and paint particles on the surface.

[0004] However, traditional grinding tables are mostly composed of a simple table, which generates a lot of dust and iron filings during the grinding process. If they are not cleaned in time, these impurities will not only adhere to the surface of the parts, affecting their precision and quality, but may also drift into the air in the workshop, posing a health hazard to the operators. Furthermore, when moving the workpiece, the metal particles on the table may scratch the workpiece. Therefore, a dust removal device for automotive parts processing is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one technical problem in the background art, this utility model proposes a dust removal device for automotive parts processing.

[0018] 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.

[0019] Example 1 Please see Figure 1-5 As shown, a dust removal device for processing automotive parts includes a bracket 1, a ring frame 2 fixedly connected to the surface of the bracket 1, and a processing table 3 fixedly connected to the ring frame 2. The processing table 3 is mesh. A guide plate 12 is fixedly connected to the surface of the ring frame 2, and a feeding pipe is fixedly connected to the bottom of the guide plate 12; A main collection box 13 is provided at the bottom of the feed pipe to collect iron filings and impurities; A secondary air duct 8 is connected through the surface of the feed pipe. The secondary air duct 8 is V-shaped with an included angle greater than 90 degrees. A main air duct 6 is connected through the surface of the secondary air duct 8. A motor 7 is fixedly connected to the surface of the main air duct 6. The main air duct 6 is fixedly connected to a top cover 5 at its end, and the opening of the main air duct 6 passes through the top cover 5. A filter screen 11 is installed inside the secondary air duct 8. An installation groove 15 is opened on the surface of the secondary air duct 8. The filter screen 11 is slidably installed in the installation groove 15. A sealing ring is fixedly connected to the surface of the filter screen 11. The guide plate 12 is an eccentric cone shape, and the main collection box 13 is screwed onto the surface of the feed pipe. During operation, motor 7 is turned on, causing it to blow air into the main air duct 6. The negative pressure generated by the airflow in the main air duct 6 forces air into the processing table 3, through the secondary air duct 8, and back into the main air duct 6, finally returning to the processing table 3 in a cycle. The part to be polished is then placed on the processing table 3 for polishing. The polishing debris falls into the main collection box 13 under gravity. The dust generated is guided by the airflow into the secondary air duct 8, filtered through the filter screen 11 inside the secondary air duct 8, and then blown back out of the main air duct 6. This helps to direct the dust towards the secondary air duct 8, and through the motor 7 and main air duct 6, the dust is further dispersed. The cooperation between duct 6 and auxiliary duct 8 can remove the dust generated during the grinding process, preventing it from adhering to the surface of parts or drifting into the air in the workshop. Under the action of gravity, the iron filings fall into the main collection box 13, and then the main collection box 13 can be disassembled and cleaned by threads. This not only prevents residual metal particles on the table from scratching the workpiece, but also allows for the recycling of excess iron filings. Because the guide plate 12 is conical, it can guide the iron filings that fall off the surface of the mesh processing table 3 into the main collection box 13. Because the filter screen 11 is detachable, it is convenient for staff to replace it regularly.

[0020] Multiple air distribution pipes 16 are fixedly connected to the surface of the top cover 5. Each air distribution pipe 16 is ring-shaped and has multiple air nozzles connected through it. Each air distribution pipe 16 is connected to each other through a pipe and is supplied with air by the main air pipe 6. Each air nozzle is equipped with a pressure relief valve. An air guide hood 9 is fixedly connected to the surface of the top cover 5. The air guide hood 9 is frustoconical and has an air guide groove on its inner wall. During operation, air flows from the main air duct 6 to the distribution air duct 16, causing a large area of ​​air to be blown onto the processing table 3. At the same time, with the cooperation of the air guide hood 9 and its surface air guide grooves, the generated air force can be concentrated, which can prevent the airflow from dispersing and improve the dust removal effect. The pressure relief valve can also be an elastic pore with elastic diaphragm surface, which can withstand less pressure. Therefore, when the distribution air duct 16 is completely filled with air, the pressure relief valve will open completely under the action of air pressure, thereby achieving a uniform air output effect. This avoids the situation where the air pressure is high near the main air duct 6 and gradually decreases towards the outer circle, further improving the dust removal effect.

[0021] A spindle 17 is rotatably connected to the inner wall of the secondary air duct 8. A rotating plate 18 is rotatably connected to the surface of the spindle 17 via a spring. A brush is fixedly connected to the surface of the rotating plate 18. A discharge chute is opened on the surface of the secondary air duct 8. A baffle 20 is fixedly connected to the inner wall of the secondary air duct 8 relative to the discharge chute. A secondary collection box 21 is fixedly connected to the surface of the secondary air duct 8 by bolts. During operation, the particles in the dust are relatively light, so they will be adsorbed onto the surface of the filter screen 11 under the action of the airflow. When the airflow passes through the secondary air duct 8, it will be blown towards the rotating plate 18 under the action of the baffle 20. Because the rotating plate 18 is made of plastic, which is relatively light, the rotating plate 18 will be blown towards the rotating plate 18 under the action of the wind. The rotating plate 18 rotates and, in conjunction with the brush at its end, cleans the filter screen 11. When the rotating plate 18 rotates to the position of the baffle 20, it rotates under the pressure of the baffle 20 until it passes through the baffle 20, and then returns to its original position under the action of the spring. When the rotating plate 18 passes through the baffle 20, the scraped impurities fall into the secondary collection box 21. Because the secondary collection box 21 has an observation window 22 on its surface, the staff can disassemble and clean the secondary collection box 21 at any time by using bolts. Using the rotating plate 18 to drive the brush to clean the filter screen 11 can extend its service life, reduce the number of replacements, and thus bring better economic benefits.

[0022] Example 2 Please see Figure 6 As shown in the first embodiment, as another implementation of this utility model, the support 1 is fixedly connected with a movable wheel 23, which is a self-locking universal wheel; when working, the universal wheel is unlocked, and then the support 1 can be pushed to move. After reaching the designated position, it is locked to prevent movement. The movable wheel 23 with self-locking function can improve the convenience of overall movement.
