Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, specifically a waterproof and fog-proof polishing machine. Background Technology

[0002] A polishing machine is driven by a motor to rotate a polishing wheel mounted on it. Under the action of the polishing wheel and polishing liquid, the polishing wheel rubs the surface of the workpiece to be polished, thereby achieving the purpose of removing paint contamination, oxide layer and shallow scratches.

[0003] During the polishing process, polishing slurry is sprayed onto the surface of the workpiece. When the polishing wheel polishes the workpiece, the polishing slurry splashes everywhere. If this polishing slurry gets into the drive components of the polishing machine, such as the guide rail, lead screw, and motor, it will corrode these components over time, causing them to rust and affecting the processing accuracy.

[0004] During the polishing process, the polishing compound generates heat through friction with the workpiece surface, causing the moisture in the polishing compound to evaporate and form water vapor. If the polishing environment has high humidity, or if the polishing compound contains volatile components, fog may be generated. Fog can affect the clarity of the processed area. Furthermore, if this water vapor and fog penetrate into electronic components such as motors, it can cause the internal electrical components to become damp or corroded, affecting the service life of these electronic components. If this water vapor and fog penetrate into components such as slide rails or lead screws, it can cause these components to rust over time, thus affecting the processing accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof and fog-proof polishing machine to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A waterproof and fog-proof polishing machine includes a bed, a first slide, a second slide, a workpiece clamping mechanism, a polishing mechanism, and an air curtain mechanism. The bed and the first slide are fixedly connected, the first slide and the second slide are fixedly connected, the workpiece clamping mechanism and the second slide are fixedly connected, the polishing mechanism and the bed are fixedly connected, the air curtain mechanism and the bed are fixedly connected, and the first slide and the air curtain mechanism are slidably connected.

[0008] The workpiece is held by a workpiece clamping mechanism, allowing the polishing mechanism to polish it. The first and second slides enable the workpiece clamping mechanism to move up, down, left, and right, flexibly adjusting the workpiece's position to ensure the polishing mechanism makes full and uniform contact with the workpiece surface. An air curtain mechanism creates an air curtain between the first and second slides, the workpiece clamping mechanism, and the polishing mechanism, preventing polishing fluid from flying towards the slides and avoiding the penetration of mist and moisture into the slide area. This prevents rusting of the slides due to mist and moisture, thus extending the equipment's lifespan.

[0009] Furthermore, the air curtain mechanism includes an air compressor and an air distributor, with the air compressor and air distributor connected by pipes, and the air distributor fixedly connected to the bed.

[0010] An air compressor delivers compressed air through pipes to an air distributor, which then sprays the compressed air out, creating an air curtain between the ram and the polishing area. This isolates the ram from the polishing area, keeping the ram area dry and reducing problems such as poor lubrication, rust, and oxidation caused by moisture and mist, thereby extending the ram's service life.

[0011] Furthermore, the first slide includes a first motor, a first lead screw, a first nut, a first support base, a first guide rail, a first slider, a first mounting bracket, a first baffle, and a second guide rail. The first motor is fixedly connected to the bed, the output end of the first motor is fixedly connected to the first lead screw, the first nut is threadedly connected to the first lead screw, the first support base is rotatably connected to the first lead screw, the first guide rail is fixedly connected to the bed, the first slider is slidably connected to the first guide rail, the first mounting bracket is fixedly connected to the first nut, the first mounting bracket is fixedly connected to the first slider, the first mounting bracket is fixedly connected to the first baffle, the first baffle is fixedly connected to the bed, the second guide rail is fixedly connected to the bed, and the second guide rail is slidably connected to the first baffle.

[0012] The first motor drives the first lead screw to rotate, which is supported by the first support base, ensuring smooth rotation. The first nut, threadedly connected to the first lead screw, moves the first mounting bracket left and right. The first guide rail and first slider ensure smooth movement of the mounting bracket. A first baffle seals the area where the mounting bracket slides left and right. This flexible baffle extends and retracts with the movement of the slide block, ensuring effective isolation between the slide block and the polishing area during polishing. This prevents coolant from splashing into the slide block area, thus avoiding corrosion of the guide rail and lead screw, and preventing rust that could affect the slide block's movement accuracy. A second guide rail allows the first baffle to fold and unfold according to preset creases, completely covering the designated area and ensuring effective isolation.

[0013] Furthermore, the second slide includes a second motor, a first machine base, a second lead screw, a second nut, a second support base, and a second baffle. The second motor is fixedly connected to the first machine base, the output end of the second motor is fixedly connected to the second lead screw, the first machine base is fixedly connected to the first mounting bracket, the second nut is threadedly connected to the second lead screw, the second nut is fixedly connected to the second baffle, the second support base is fixedly connected to the first mounting bracket, the second support base is rotatably connected to the second lead screw, and the second baffle is fixedly connected to the workpiece clamping mechanism.

[0014] The No. 1 base and the No. 2 support base are fixedly connected to the No. 1 mounting frame, allowing the No. 2 slide block to move with the No. 1 mounting frame. The No. 2 motor drives the No. 2 lead screw to rotate, causing the No. 2 nut to move the No. 2 baffle up and down. This allows the workpiece clamping mechanism to move up and down with the No. 2 baffle. By fixing both ends of the No. 2 baffle to the No. 1 baffle, the through groove reserved in the No. 1 baffle for the workpiece clamping mechanism to move up and down is closed, thus isolating the working area of ​​the slide block from the polishing area. By making the No. 2 baffle a flexible baffle, it can fold and unfold with preset creases when moving up and down, thus ensuring that the workpiece clamping mechanism always isolates the processing and moving parts when moving.

[0015] Furthermore, the workpiece clamping mechanism includes a No. 3 motor, a No. 2 machine base, a clamp, a No. 3 machine base, a spindle, a fixture, a No. 4 motor, and a motor cover. The No. 3 motor is fixedly connected to the No. 2 machine base, the No. 2 machine base is fixedly connected to the No. 2 baffle, the output end of the No. 3 motor is fixedly connected to the clamp, the No. 3 machine base is fixedly connected to the clamp, the spindle and the clamp are rotatably connected, the No. 4 motor is fixedly connected to the No. 3 machine base, the output end of the No. 4 motor is fixedly connected to the spindle, the fixture is fixedly connected to the spindle, and the motor cover is fixedly connected to the No. 3 machine base.

[0016] The clamp is driven to rotate by motor number three, allowing the fixture to be adjusted at an angle relative to the polishing mechanism. The spindle is driven to rotate by motor number four, thereby changing the position of the workpiece for polishing. This allows the polishing mechanism to make more comprehensive contact with the workpiece surface. The motor cover isolates motor number four from the external environment, preventing moisture and mist from entering the motor and avoiding moisture or corrosion of the electrical components inside the motor, thus extending the service life of motor number four.

[0017] Furthermore, the polishing mechanism includes a No. 5 motor, a rotating shaft, a protective cover, a polishing wheel, and a base. The No. 5 motor is fixedly connected to the bed, the output end of the No. 5 motor is fixedly connected to the rotating shaft, the rotating shaft is rotatably connected to the bed, the rotating shaft is fixedly connected to the protective cover, the polishing wheel is fixedly connected to the rotating shaft, the polishing wheel is fixedly connected to the protective cover, the base is fixedly connected to the bed, and the base is rotatably connected to the rotating shaft.

[0018] The No. 5 motor is fixedly connected to the machine bed, ensuring stable power transmission and preventing unstable polishing caused by motor vibration. The No. 5 motor drives the rotating shaft, causing the polishing wheel to rotate with the shaft, thus polishing the workpiece. A protective cover isolates the area between the rotating shaft and the polishing wheel, preventing water and mist from entering the rotating shaft and avoiding rusting or deformation / damage to the polishing wheel.

[0019] Furthermore, the air distributor is equipped with an air outlet facing the processing direction.

[0020] An air outlet is provided by the air distributor, allowing airflow to flow out and form an air curtain. This isolates the space where slides one and two are located from the processing area, preventing moisture and mist from entering. By pointing the air outlet towards the processing direction, the air curtain is tilted, causing the polishing liquid integrated into the air curtain to flow towards the processing side, preventing the polishing liquid integrated into the air curtain from spreading to the slide area. This directs the airflow towards the processing direction and blows the moisture and mist away from the processing area, ensuring the clarity of the processing area.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By using an air compressor, compressed air is delivered to the air distributor through pipelines and then ejected from the air distributor, thereby forming an air curtain between the slide and the polishing area. This isolates the slide from the polishing area, keeping the slide area dry and reducing problems such as poor lubrication, rust, and oxidation caused by moisture and mist, thus extending the service life of the slide.

[0023] 2. By pointing the air outlet toward the processing direction, the air curtain is tilted at an angle, causing the polishing liquid integrated into the air curtain to flow toward the processing side, preventing the polishing liquid integrated into the air curtain from spreading to the area of ​​the slide block, and causing the airflow to flow in the processing direction, blowing the water vapor and mist away from the processing area, ensuring the clarity of the processing area.

[0024] 3. By using baffles No. 1 and No. 2, the slide area and the processing area are separated, and the baffles always cover the predetermined area to ensure the isolation effect. This prevents polishing liquid from splashing into the slide and prevents coolant from corroding components such as guide rails and lead screws, reducing the problem of rust affecting the movement accuracy of the slide.

[0034] 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.

[0035] Example: Figure 1 and Figure 2As shown, this utility model provides a waterproof and fog-proof polishing machine technical solution. The polishing machine includes a bed 1, a first slide 2, a second slide 3, a workpiece clamping mechanism 4, a polishing mechanism 5, and an air curtain mechanism 6. The bed 1 and the first slide 2 are fixedly connected, the first slide 2 and the second slide 3 are fixedly connected, the workpiece clamping mechanism 4 and the second slide 3 are fixedly connected, the polishing mechanism 5 and the bed 1 are fixedly connected, the air curtain mechanism 6 and the bed 1 are fixedly connected, and the first slide 2 and the air curtain mechanism 6 are slidably connected.

[0036] The workpiece is held by the workpiece clamping mechanism 4, allowing the polishing mechanism 5 to polish it. The workpiece clamping mechanism 4 can move up, down, left, and right via the first slide 2 and the second slide 3, thus flexibly adjusting the position of the workpiece and ensuring that the polishing mechanism 5 can fully and evenly contact the workpiece surface. An air curtain mechanism 6 generates an air curtain between the first slide 2 and the second slide 3, the workpiece clamping mechanism 4, and the polishing mechanism 5, preventing the polishing liquid from flying towards the slides during the polishing process and preventing the mist and water vapor generated during the polishing process from penetrating into the area of ​​the slides. This avoids rusting of the slides due to mist and water vapor and improves the service life of the equipment.

[0037] like Figures 1-4 As shown, the air curtain mechanism 6 includes an air compressor 61 and an air distributor 62. The air compressor 61 and the air distributor 62 are connected by pipes, and the air distributor 62 is fixedly connected to the bed 1.

[0038] Compressed air is delivered to the air distributor 62 through the air compressor 61 via a pipeline. The compressed air is then ejected from the air distributor 62, thereby forming an air curtain between the slide and the polishing area. This isolates the slide from the polishing area, keeps the slide area dry, and reduces problems such as poor lubrication, rust, and oxidation caused by moisture and mist, thus extending the service life of the slide.

[0039] like Figures 1-5 As shown, the first slide ram 2 includes a first motor 21, a first lead screw 22, a first nut 23, a first support base 24, a first guide rail 25, a first slider 26, a first mounting bracket 27, a first baffle 28, and a second guide rail 29. The first motor 21 is fixedly connected to the bed 1. The output end of the first motor 21 is fixedly connected to the first lead screw 22. The first nut 23 is threadedly connected to the first lead screw 22. The first support base 24 is rotatably connected to the first lead screw 22. The first guide rail 25 is fixedly connected to the bed 1. The first slider 26 is slidably connected to the first guide rail 25. The first mounting bracket 27 is fixedly connected to the first nut 23. The first mounting bracket 27 is fixedly connected to the first slider 26. The first mounting bracket 27 is fixedly connected to the first baffle 28. The first baffle 28 is fixedly connected to the bed 1. The second guide rail 29 is fixedly connected to the bed 1. The second guide rail 29 is slidably connected to the first baffle 28.

[0040] The first motor 21 drives the first lead screw 22 to rotate, and the first support base 24 supports the first lead screw 22, allowing it to rotate smoothly. The first nut 23 is threadedly connected to the first lead screw 22, causing the first mounting bracket 27 to move left and right. The first guide rail 25 and the first slider 26 allow the first mounting bracket 27 to move smoothly. The first baffle 28 seals the area where the first mounting bracket 27 slides left and right. The first baffle 28 is a flexible baffle that can extend and retract with the movement of the slide block, ensuring effective isolation between the slide block and the polishing area during the polishing process. This prevents coolant from flying into the slide block area during polishing, thus avoiding corrosion of the guide rail and lead screw by the coolant and preventing rust from affecting the movement accuracy of the slide block. By setting the second guide rail 29, the first baffle 28 folds and unfolds according to the preset creases as it moves, completely covering the predetermined area and ensuring the isolation effect.

[0041] like Figures 1-6 As shown, the second slide ram 3 includes a second motor 31, a first machine base 32, a second lead screw 33, a second nut 34, a second support base 35, and a second baffle 36. The second motor 31 and the first machine base 32 are fixedly connected. The output end of the second motor 31 is fixedly connected to the second lead screw 33. The first machine base 32 and the first mounting bracket 27 are fixedly connected. The second nut 34 and the second lead screw 33 are threadedly connected. The second nut 34 and the second baffle 36 are fixedly connected. The second support base 35 and the first mounting bracket 27 are fixedly connected. The second support base 35 and the second lead screw 33 are rotatably connected. The second baffle 36 is fixedly connected to the workpiece clamping mechanism 4.

[0042] The No. 1 base 32 and the No. 2 support base 35 are fixedly connected to the No. 1 mounting frame 27, so that the No. 2 slide 3 moves with the No. 1 mounting frame 27. The No. 2 motor 31 drives the No. 2 lead screw 33 to rotate, so that the No. 2 nut 34 drives the No. 2 baffle 36 to move up and down, so that the workpiece clamping mechanism 4 moves up and down with the No. 2 baffle 36. By fixing the two ends of the No. 2 baffle 36 to the No. 1 baffle 28, the through groove reserved in the No. 1 baffle 28 for the workpiece clamping mechanism 4 to move up and down is closed, so that the working area of ​​the slide 3 and the polishing area are separated. By making the No. 2 baffle 36 a flexible baffle, it can be folded and unfolded with preset creases when moving up and down, so that the workpiece clamping mechanism 4 always separates the processing and moving parts when moving.

[0043] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the workpiece clamping mechanism 4 includes a No. 3 motor 41, a No. 2 machine base 42, a clamp 43, a No. 3 machine base 44, a spindle 45, a fixture 46, a No. 4 motor 47, and a motor cover 48. The No. 3 motor 41 is fixedly connected to the No. 2 machine base 42, the No. 2 machine base 42 is fixedly connected to the No. 2 baffle 36, the output end of the No. 3 motor 41 is fixedly connected to the clamp 43, the No. 3 machine base 44 is fixedly connected to the clamp 43, the spindle 45 is rotatably connected to the clamp 43, the No. 4 motor 47 is fixedly connected to the No. 3 machine base 44, the output end of the No. 4 motor 47 is fixedly connected to the spindle 45, the fixture 46 is fixedly connected to the spindle 45, and the motor cover 48 is fixedly connected to the No. 3 machine base 44.

[0044] The clamp 43 is driven to rotate by motor 41, which allows the clamp 46 to be angled relative to the polishing mechanism 5. The spindle 45 is driven to rotate by motor 47, thereby changing the position of the workpiece for polishing. This allows the polishing mechanism 5 to make more comprehensive contact with the workpiece surface. The motor cover 48 isolates motor 47 from the external environment, preventing moisture and mist from entering motor 47 and avoiding moisture or corrosion of the electrical components inside the motor, thus improving the service life of motor 47.

[0045] like Figure 1 and Figure 8 As shown, the polishing mechanism 5 includes a No. 5 motor 51, a rotating shaft 52, a protective cover 53, a polishing wheel 54, and a base 55. The No. 5 motor 51 is fixedly connected to the bed 1, the output end of the No. 5 motor 51 is fixedly connected to the rotating shaft 52, the rotating shaft 52 is rotatably connected to the bed 1, the rotating shaft 52 is fixedly connected to the protective cover 53, the polishing wheel 54 is fixedly connected to the rotating shaft 52, the polishing wheel 54 is fixedly connected to the protective cover 53, the base 55 is fixedly connected to the bed 1, and the base 55 is rotatably connected to the rotating shaft 52.

[0046] The No. 5 motor 51 is fixedly connected to the bed 1, ensuring stable power transmission and preventing unstable polishing caused by motor vibration. The No. 5 motor 51 drives the rotating shaft 52 to rotate, causing the polishing wheel 54 to rotate with the rotating shaft 52, thereby polishing the workpiece. The protective cover 53 isolates the area between the rotating shaft 52 and the polishing wheel 54, preventing water and mist from entering the rotating shaft 52 and avoiding rust on the rotating shaft 52 and deformation or damage to the polishing wheel 54.

[0047] like Figures 2-4 As shown, the air distributor 62 is provided with an air outlet 621, which faces the processing direction.

[0048] The air distributor 62 has an air outlet 621, which allows airflow to flow out and form an air curtain, thereby isolating the space where the first slide 2 and the second slide 3 are located from the processing area, preventing water vapor and mist from entering. By pointing the air outlet 621 toward the processing direction, the air curtain is tilted, causing the polishing liquid integrated into the air curtain to flow toward the processing side, preventing the polishing liquid integrated into the air curtain from spreading to the area of ​​the slide 2. The airflow is directed toward the processing direction, and the water vapor and mist are blown away from the processing area, ensuring the clarity of the processing area.

[0049] Working Principle: Motor 51 drives the rotating shaft 52 to rotate, causing the polishing wheel 54 to rotate with the shaft, thus polishing the workpiece. Through slides 2 and 3 and the workpiece clamping mechanism 4, the workpiece can rotate up, down, left, right, clockwise, counterclockwise, or along the main shaft 45, allowing for angle and position adjustments. This facilitates more comprehensive contact between the polishing mechanism 5 and the workpiece surface, improving polishing efficiency and quality. Baffles 28 and 36 keep slides 2 and 3 isolated from the polishing area, preventing cold air from entering during polishing. The coolant is prevented from entering the slide area, thus avoiding corrosion of components such as guide rails and lead screws. Compressed air is delivered to the air distributor 62 through the air compressor 61 via pipeline. The compressed air is sprayed out from the air distributor 62, thereby forming an air curtain between the slide and the polishing area. By pointing the air outlet 621 towards the processing direction, the air curtain is tilted at an angle, causing the polishing liquid integrated into the air curtain to flow towards the processing side, preventing the polishing liquid integrated into the air curtain from spreading to the slide area. The airflow is directed towards the processing direction, and the water vapor and mist are blown away from the processing area to ensure the clarity of the processing area.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
