Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to an automatic dust removal pretreatment device for metal surface spraying. Background Technology

[0002] With the advancement of Industry 4.0 and smart manufacturing concepts, the manufacturing industry is moving towards automation and intelligence. In the field of metal processing and surface treatment, automatic dust removal pretreatment devices conform to this trend, enabling automated control of the production process, improving production efficiency, reducing labor costs, minimizing quality fluctuations caused by human factors, ensuring product quality consistency and stability, and adapting to the needs of large-scale production.

[0003] In existing technologies, the air supply pipelines required for the automatic dust removal pretreatment devices before metal surface spraying are usually designed to be too long. These redundant pipelines are difficult to organize and inevitably scatter and accumulate in the ground work area. This not only makes the work site messy, but more importantly, it poses a serious safety risk. Pipelines on the ground can easily trip up operators and inspectors who are moving around, causing personal injury accidents. At the same time, pipelines may become tangled or knotted with each other or with equipment components. This may not only damage the pipelines themselves, but also interfere with the normal operation of the equipment, and even lead to unplanned shutdowns. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic dust removal pretreatment device for metal surface spraying.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic dust removal pretreatment device for metal surface spraying, comprising a processing table, an air pump fixed at the bottom of the processing table, an air pipe connected to the surface of the air pump, and an air gun connected to the other end of the air pipe, a bracket fixed at the upper end of the processing table, a fixture fixed at the upper end of the bracket, a fixed base fixed at the side end of the fixture, a rotating rod fixed to the surface of the fixed base, a rotating disk rotatably connected to the circumference of the rotating rod, an annular partition fixed at one end of the rotating disk, a locking block engaged on the surface of the annular partition, the locking block being fixedly connected to the air pipe, a return spring fixed to the inner wall of the annular partition, one end of the return spring being fixedly connected to the rotating rod, an annular groove formed at the other end of the rotating disk, a protrusion fixed to the inner wall of the annular groove, a ball slidably connected to the surface of the annular groove, a limiting piece fixed to the inner wall of the annular groove, an outlet groove formed inside the annular groove, and a recessed groove formed at the side end of the fixed base, the surface of the recessed groove being slidably connected to the ball.

[0006] Preferably, a fixed base is fixed to the upper end of the processing table, a screw is rotatably connected to the upper end of the fixed base, a clamp is threadedly connected to the surface of the screw, a rotating rod is rotatably connected to the side end of the screw, a crank is fixed to the side end of the rotating rod, a fixed spring is fixed to the surface of the rotating rod, a chuck is rotatably connected to the side end of the fixed spring, the chuck is rotatably connected to the rotating rod, and a driven plate is fixed to the surface of the screw, the driven plate meshing with the chuck. In the prior art, the clamping mechanism of traditional processing devices often adopts a fixed mechanical structure, which cannot automatically adjust the clamping force according to factors such as the material, shape, size, and surface condition of the metal block. Whether it's a metal with low hardness like aluminum or copper, or a metal with high hardness like steel, using the same force during clamping can easily lead to the softer metal block being over-clamped, causing deformation, indentations, and other damage. To address this problem, this invention uses a novel force-limiting structure. When the clamping plate reaches the surface of the metal block, continuing to rotate the handle will cause the chuck and driven plate to disengage, preventing the driven chuck from rotating and thus protecting the metal block. This significantly improves the safety of the device's operation.

[0007] Preferably, the fixed spring is a double-strand spring. During long-term reciprocating motion or vibration, the double-strand spring can share the stress with each other, which significantly improves its fatigue resistance compared to a single-strand spring. This reduces failure problems such as relaxation and breakage caused by fatigue, extends the service life of the spring, and reduces the maintenance cost and replacement frequency of the equipment.

[0008] Preferably, a mounting plate is fixed to the surface of the processing table. The mounting plate has an arc groove and a square slot. The shapes of the arc groove and square slot are adapted to the body and connecting parts of the air gun, enabling the air gun to quickly and accurately engage in the slot, achieving rapid positioning and fixation. Operators do not need to spend excessive time finding a suitable mounting position or performing complex fixing operations; they only need to gently place the air gun into the slot to complete the mounting, improving work efficiency.

[0009] Preferably, a triangular locking block is fixed to the bottom of the mounting plate, and the side end of the triangular locking block is fixed to the processing table. After the triangular locking block is fixed to the processing table, it provides an additional support point for the mounting plate. In addition to the direct connection between the mounting plate and the processing table, the triangular locking block can further distribute the force on the mounting plate, making the mounting plate more stable when bearing the weight of equipment such as jet guns, and reducing the risk of shaking and displacement.

[0010] Preferably, the crank handle is fixed with a rubber sleeve, the surface of which has anti-slip texture. The rubber sleeve has a certain degree of flexibility and elasticity, which can adapt to the contour of the hand and provide a more comfortable grip. During long-term operation, the operator's hand will not feel fatigued or uncomfortable due to prolonged gripping, thus improving work efficiency and operating experience.

[0011] Beneficial effects:

[0012] 1. In existing technologies, the air supply pipelines required for the power source of automatic dust removal pretreatment devices before metal surface spraying are usually designed to be too long. These redundant pipelines are difficult to organize and inevitably scatter and accumulate in the ground work area. This not only makes the work site messy, but more importantly, it poses a serious safety risk. Pipelines on the ground can easily trip up operators and inspectors, causing personal injury accidents. At the same time, pipelines may become entangled or knotted with each other or with equipment components. This may not only damage the pipelines themselves, but also interfere with the normal operation of the equipment, and even lead to unplanned shutdowns. To address these problems, this utility model adopts a novel rotating structure. With the help of a return spring and a rotating disk, the air pipes are stored inside the rotating disk, thereby reducing the space occupied by excess air pipes and improving the safety of the device operation.

[0013] 2. In existing technologies, the clamping mechanisms of traditional processing devices often employ fixed mechanical structures, which cannot automatically adjust the clamping force according to factors such as the material, shape, size, and surface condition of the metal block. Whether it's a low-hardness metal like aluminum or copper, or a high-hardness metal like steel, the same force is applied during clamping. This easily leads to over-clamping of softer metal blocks, causing deformation, indentations, and other damage. To address this problem, this invention uses a novel force-limiting structure. When the clamping plate reaches the surface of the metal block, further rotation of the handle causes the chuck and driven plate to disengage, preventing the driven chuck from rotating and thus protecting the metal block, significantly improving the operational safety of the device.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0025] Reference Figure 1-6An automatic dust removal pretreatment device for metal surface spraying includes a processing table 1. An air pump is fixed to the bottom of the processing table 1, and an air pipe 101 is connected to the surface of the air pump. The other end of the air pipe 101 is connected to an air gun. A bracket 102 is fixed to the upper end of the processing table 1, and a fixture 2 is fixed to the upper end of the bracket 102. A fixed base 201 is fixed to the side end of the fixture 2. A rotating rod 206 is fixed to the surface of the fixed base 201, and a rotating disk 202 is rotatably connected to the circumference of the rotating rod 206. One end of the rotating disk 202 is fixed with an annular... The annular partition 203 has a locking block 204 attached to its surface, which is fixedly connected to the air pipe 101. A return spring 205 is fixedly fixed to the inner wall of the annular partition 203, with one end of the return spring 205 fixedly connected to the rotating rod 206. The other end of the rotating disk 202 has an annular groove 207, with a protrusion 209 fixed to the inner wall of the annular groove 207. A ball 208 is slidably connected to the surface of the annular groove 207, and a limiting piece 210 is fixed to the inner wall of the annular groove 207. A groove is formed inside the annular groove 207. 211. A recess 212 is provided on the side of the fixed chassis 201. The surface of the recess 212 is slidably connected to the ball bearing 208. In the prior art, the air supply pipe 101 required for the power air source of the automatic dust removal pretreatment device before metal surface spraying is usually designed to be too long. These redundant pipes are difficult to store neatly and inevitably scatter and accumulate in the ground work area. This not only makes the work site messy, but more importantly, it poses a serious safety risk. Pipes on the ground are very likely to trip the operators and inspectors who are passing by, causing personal injury accidents. At the same time, the pipes may also become entangled or knotted with each other or with equipment parts. This may not only damage the pipes themselves, but also interfere with the normal operation of the equipment, and even lead to unplanned shutdowns. In order to solve such problems, this utility model adopts a new rotating structure. With the help of the return spring 205 and the rotating disk 202, the air pipe 101 is stored inside the rotating disk 202, thereby reducing the space occupied by the redundant air pipe 101 and improving the safety of the device operation.

[0026] A fixed base 3 is fixed to the upper end of the processing table 1. A screw 301 is rotatably connected to the upper end of the fixed base 3. A clamping plate is threaded onto the surface of the screw 301. A rotating rod 302 is rotatably connected to the side end of the screw 301. A crank handle 303 is fixed to the side end of the rotating rod 302. A fixed spring 304 is fixed to the surface of the rotating rod 302. A chuck 305 is rotatably connected to the side end of the fixed spring 304. The chuck 305 is rotatably connected to the rotating rod 302. A driven plate 306 is fixed to the surface of the screw 301. The driven plate 306 meshes with the chuck 305. The fixed spring 304 is a double-strand spring. A mounting plate 5 is fixed to the surface of the processing table 1. An arc groove is opened on the surface of the mounting plate 5. A square slot is opened on the surface of the mounting plate 5. A triangular block 204 is fixed to the bottom of the mounting plate 5. The side end of the triangular block 204 is fixed to the processing table 1. A rubber sleeve is fixed to the surface of the crank handle 303. The surface of the rubber sleeve is provided with anti-slip texture.

[0027] The working principle of this utility model is as follows: When a metal block needs dust removal, the operator first places the metal block between the clamping plates. Simultaneously, the operator cranks the handle 303 to clamp the metal block until the chuck 305 repeatedly disengages from the driven plate 306. Then, the device is activated, and the air pump starts working, generating compressed air. This compressed air is transmitted through the air pipe 101 to the air gun, which sprays the compressed air onto the metal surface, thus achieving automatic dust removal. The high-pressure airflow from the air gun blows away dust, oil, and other impurities adhering to the metal surface, providing a clean surface for subsequent spraying operations. Furthermore, the long portion of the air pipe 101 is retracted by the rotating plate 202 and the return spring 205. When the operator needs to adjust the external length of the air pipe 101, they only need to pull... The air tube 101 is in place. At this time, the ball 208 moves inside the annular groove 207. After reaching the specified length, the operator releases the air tube 101. At this time, due to the inclined surface of the protrusion 209, the ball 208 will move into the annular groove 207 and get stuck inside the annular groove 207. When the operator needs to retract the air tube 101, they only need to pull the air tube 101 again to rotate the rotating disk 202, which will cause the ball 208 to move along the annular groove 207 where the limiting plate 210 is located. Then, the air tube 101 is released. Due to the protrusion inside the limiting plate 210, the ball 208 is prevented from rotating along the limiting plate 210, so that the ball 208 returns to its original position along the groove 211. This causes the return spring 205 to drive the rotating disk 202 to retract the air tube 101, completing the storage.
