Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to a dust-free polishing equipment for the surface of metal products. Background Technology

[0002] This equipment is used for grinding and polishing the surface of metal products. It also has a built-in dust removal system to collect metal dust generated during the polishing process in real time, so as to avoid dust spreading and polluting the environment and harming the health of operators. It balances processing accuracy and cleanliness and is widely used in hardware manufacturing, automotive parts processing and other fields.

[0003] Existing metal polishing equipment uses a motor to drive polishing wheels, polishing columns, and other polishing components to rotate at high speed. Polishing is achieved through friction between the polishing components and the surface of the metal product. Simultaneously, a fan located beside or inside the equipment generates negative pressure through ducts, drawing the polishing dust into a filtration device. The filtered clean air is then discharged, and the collected dust is periodically cleaned. Some simpler equipment even requires an additional mobile dust collector, which collects dust through external ducts.

[0004] In existing technologies, some polishing equipment is designed with a detachable fixed structure to facilitate the replacement of polishing columns of different specifications to meet the polishing needs of different products. However, in actual use, when the polishing column is removed and reinstalled, the original fixed parts are prone to wear and assembly deviations, which can lead to a decrease in the fixing strength and loosening of the polishing column. This can result in damage to the polishing parts and workpieces due to collisions between the polishing column and the product, increasing the rework rate and equipment maintenance costs. Therefore, a dust-free polishing equipment for metal product surfaces is proposed to solve the above problems. Utility Model Content

[0032] 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.

[0033] Example:

[0034] A dust-free polishing device for metal product surfaces, referring to Figures 1 to 3 The device includes an outer shell 1. A sedimentation tank 2 is provided on the lower side of the inner side of the outer shell 1. The sedimentation tank 2 is used to collect various dust particles generated during polishing. The bottom slope design facilitates the centralized cleaning of dust. A buffer chamber 6 is provided inside the outer shell 1. The buffer chamber 6 buffers and slows down the dust-laden airflow, allowing some dust to settle. A fan 5 is fixedly connected inside the outer shell 1. The fan 5 provides negative pressure power and draws in the dust-laden airflow through the air inlet 3 to achieve dust collection. The outer shell 1 is used to form a closed polishing working space to prevent dust from overflowing and protect the internal components. An air outlet 7 is fixedly connected to the output end of the fan 5. The air outlet 7 discharges the filtered clean air from the device. An air inlet 3 is provided at the input end of the fan 5. The air inlet 3 integrates a multi-stage filtration structure. A polishing mechanism 4 is provided inside the outer shell 1. The polishing mechanism 4 is responsible for polishing metal products.

[0035] Specifically, when the dust-free polishing equipment for metal products is working, a closed space is first formed through the outer shell 1, and the polishing mechanism 4 is started to polish the metal products. At the same time, the fan 5 is started to generate negative pressure, which draws the dust generated during polishing into the air inlet 3. During the process, the buffer chamber 6 first buffers and slows down the dust-laden airflow to settle some of the dust. The multi-stage filtration structure of the air inlet 3 further filters the dust. Finally, the dust falls into the sedimentation tank 2 with the bottom slope design for centralized collection, and the filtered clean air is discharged from the equipment through the air outlet 7, realizing dust-free polishing operation.

[0036] The polishing mechanism 4 includes a motor 43, which drives various transmission components. The motor 43 is externally and fixedly connected to the inside of the housing 1. A second connecting ring 49 is fixedly connected to the drive end of the motor 43. The second connecting ring 49 transmits the torque of the motor 43 to the first connecting ring 42 and cooperates with the sliding column 48 to achieve axial limiting. The sliding column 48 is slidably connected inside the second connecting ring 49. The annular groove on the outside of the sliding column 48 is used to lock the position of the second connecting ring 49 to achieve transmission stability. A fixed arc plate 45 is rotatably connected to the outside of the sliding column 48. The fixed arc plate 45 locks and unlocks the second connecting ring 49 by rotation. It cooperates with the fixing component 46 to fix the first connecting ring 42. A limit shaft 47 is rotatably connected inside the fixed arc plate 45. The limit shaft 47 restricts its radial displacement through the limit frame 44. The fixed arc plate 45 is internally provided with a fixing component 46. The fixing component 46 rigidly fixes the connecting ring 42 to the fixed arc plate 45 through a threaded connection to ensure that it does not loosen during polishing. The sliding column 48 is externally slidably connected to the connecting ring 42, which transmits rotational power to the polishing column 41. The polishing column 41 is externally fixedly connected to the connecting ring 42. The polishing column 41 directly contacts the metal product and achieves surface polishing through rotational friction. The connecting ring 42 is externally fixedly connected to a limit frame 44, which is used to limit the rotation range of the fixed arc plate 45 to ensure the structural fit accuracy. The limit frame 44 is internally fixedly connected to the two external ends of the limit shaft 47. The sliding column 48 is provided with two annular grooves on its exterior. The connecting ring 49 is externally slidably connected to the exterior of the sliding column 48.

[0037] The fixing component 46 includes a threaded hole 461, which is used to detachably fix the connecting ring 42 to the fixing arc plate 45. The threaded hole 461 is opened on the outside of the connecting ring 42, and the threaded hole 461 is provided with threads. The internal threads of the connecting ring 42 are connected to a bolt 462. The bolt 462 fastens the connecting ring 42 to the fixing arc plate 45 through thread engagement, ensuring stable connection during polishing. The external threads of the bolt 462 are connected to the inside of the fixing arc plate 45.

[0038] Specifically, when the polishing mechanism 4 is working, the motor 43 starts and drives the second connecting ring 49 to rotate. The second connecting ring 49 transmits torque through its cooperation with the sliding column 48. The annular groove on the outside of the sliding column 48 ensures that the second connecting ring 49 is axially positioned stably. At the same time, the fixed arc plate 45 rotates around the limiting shaft 47, and the fixed component 46 rigidly fixes the first connecting ring 42 to the fixed arc plate 45, so that the first connecting ring 42 rotates synchronously with the transmission component, and finally drives the externally fixed polishing column 41 to rotate. The surface polishing is achieved through the friction between the polishing column 41 and the metal product.

[0039] Reference Figure 2 , Figure 4 and Figure 5The air inlet 3 includes a frame 31, which is used to enable quick assembly and disassembly of the filter assembly. The frame 31 is externally slidably connected to the inside of the housing 1. A primary filter baffle 35 is fixedly connected inside the frame 31. The primary filter baffle 35 first intercepts large metal debris and dust particles, preventing them from entering the subsequent system and causing blockage or wear. The primary filter baffle 35 is externally slidably connected to the input end of the fan 5. A guide baffle 36 is fixedly connected to the outside of the primary filter baffle 35. The guide baffle 36 is used to guide the dust-laden airflow evenly through the high-efficiency filter baffle 37, avoiding filtration dead zones and dust escape caused by airflow turbulence. The outside of the guide baffle 36... A high-efficiency filter baffle 37 is fixedly connected. The high-efficiency filter baffle 37 filters fine dust particles through a fine filter screen to ensure the cleanliness of the airflow entering the fan 5. The bottom of the buffer chamber 6 is sloped. A sound-absorbing layer 32 is fixedly connected to the outside of the high-efficiency filter baffle 37. The sound-absorbing layer 32 uses sound-absorbing cotton to absorb the operating noise of the fan 5. Two fixed grooves 33 are fixedly connected to the outside of the outer shell 1. The fixed grooves 33 provide sliding tracks and limit bases for the sliding baffle 34 to ensure its stable operation. The sliding baffle 34 is slidably connected to the outside of the fixed grooves 33. The sliding baffle 34 realizes the fixing and release of the frame 31 by sliding to prevent the frame 31 from accidentally falling off during equipment operation.

[0040] Specifically, when the air inlet 3 is working, the negative pressure generated by the fan 5 draws in the dust-laden airflow. The airflow first passes through the primary filter baffle 35 to intercept large dust particles, and then is guided by the guide baffle 36 to flow evenly to the high-efficiency filter baffle 37 to filter fine dust and ensure that the airflow entering the fan 5 is clean. The sound-absorbing layer 32 absorbs the operating noise of the fan 5 at the same time. The dust generated by filtration finally falls into the buffer chamber 6 of the bottom slope and slides into the sedimentation tank 2. The frame 31 serves as the carrier of the filter component and can be disassembled as a whole. The sliding baffle 34 slides along the fixed groove 33 to realize the fixation and release of the frame 31 and prevent it from accidentally falling out during operation.

[0041] The implementation principle of this application embodiment is as follows: According to the polishing requirements of metal products, the operator selects the corresponding shape and size of the polishing column 41. During installation, first align the connecting ring 1 42 with the connecting ring 2 49, push the connecting ring 1 42 to insert the connecting ring 2 49 into it, and then slide it along the outside of the sliding column 48. Next, turn the fixed arc plate 45 to rotate it around the limiting shaft 47. The limiting shaft 47 is fixed in the limiting frame 44 to play a limiting role. At the same time, pull the sliding column 48 to lock the connecting ring 2 49 through the external groove of the sliding column 48. Finally, tighten the bolt 462 to fix it in the threaded hole 461. When replacing the polishing column 41, first turn the bolt 462 to remove it, then turn the fixed arc plate 45 to rotate it around the limiting shaft 47 to release the locking of the connecting ring 2 49, and finally pull out the connecting ring 1 42.

[0042] The motor 43 drives the connecting ring 49 to rotate, which in turn drives the connecting ring 42 to rotate, thereby rotating the polishing column 41 for polishing. When the polishing operation starts, the fan 5 starts simultaneously, and the air inlet 3 at its input end generates negative pressure, drawing the dust generated during polishing inside the outer casing 1 into the air inlet 3 to prevent the dust from spreading inside the outer casing 1. The dust first passes through the buffer chamber 6, and then large dust particles are intercepted by the primary filter baffle 35. These large particles cannot pass through the baffle due to gravity and slide down the inner wall of the outer casing 1 into the bottom sedimentation tank 2. Subsequently, the guide baffle 36 guides the airflow containing fine dust to flow evenly to the high-efficiency filter baffle 37. To prevent dust from escaping due to turbulent airflow, the high-efficiency filter baffle 37 filters fine dust through a fine filter screen, preventing it from entering the fan 5. The filtered dust also falls back to the sedimentation tank 2 along the airflow direction, ensuring that the airflow entering the fan 5 contains only trace amounts of dust. At the same time, the sound-absorbing layer 32 absorbs the operating noise of the fan 5 through sound-absorbing cotton, and also prevents residual extremely fine dust from directly impacting the impeller of the fan 5. After long-term use, dust accumulates. When the frame 31 needs to be replaced, pull the external handle to pull it out. After replacement, put it back. The frame 31 is slid to the outside of the outer shell 1 by the sliding baffle 34 and fixed by the fixing groove 33 to prevent it from falling out.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
