Description

Technical Field

[0001] This utility model relates to the field of metal polishing technology, specifically to an adaptive polishing machine for metal parts processing. Background Technology

[0002] Adaptive polishing machines for metal parts processing are advanced equipment used for polishing metal surfaces. They can automatically adjust polishing parameters according to the shape, roughness, and other characteristics of the metal surface, and can polish metal parts to obtain high-quality metal surfaces.

[0003] However, existing technologies still have the following problems:

[0004] First, when metal parts are clamped, they may shift or shake due to vibrations caused by the operation of the equipment. During high-speed grinding and polishing, metal parts may accidentally fly out due to loosening. It is inconvenient to clamp and fix metal parts, and they are prone to shifting, which cannot protect the personal safety of operators.

[0005] Secondly, after prolonged use, sanding belts naturally loosen. If the belt is too loose, it may slip and wear unevenly; if it is too tight, it may have excessive internal tension and break easily. This makes it difficult to effectively adjust the tightness of the sanding belt, resulting in low practicality.

[0006] To address the aforementioned problems, the inventors propose an adaptive polishing machine for metal parts processing. Utility Model Content

[0007] To address the problems of inconvenience in clamping and fixing metal parts, which can easily lead to displacement, and the difficulty in effectively adjusting the tension of the abrasive belt, the purpose of this utility model is to provide an adaptive polishing machine for metal part processing.

[0008] To solve the above technical problems, the present invention adopts the following technical solution: an adaptive polishing machine for metal parts processing, including a table, a polishing device fixedly connected to the center of the top surface of the table, and clamping devices fixedly connected to both sides of the top surface of the table. The clamping devices include protective shells fixedly connected symmetrically, a first rotating shaft movably passing through the lower end of the protective shell, a sprocket fixedly connected to the bottom end of the first rotating shaft, a chain meshing between the sprockets, a first motor fixedly connected to the inner wall of the table, the output end of the first motor fixedly connected to one of the sprockets, a first rotating plate fixedly connected to the top end of the first rotating shaft, the chain drive causing another sprocket to rotate synchronously, the first rotating shaft also rotating synchronously as the sprocket rotates, thereby causing the first rotating plate at the top to rotate, a second rotating plate symmetrically rotatably connected to the bottom surface of the first rotating plate, a fixing block rotatably connected to one side of the second rotating plate, a clamping plate fixedly connected to the side of the fixing block away from the second rotating plate, a limit block symmetrically fixedly connected to the lower end of the clamping plate, and two limit grooves symmetrically formed on the top surface of the protective shell for use with the limit blocks.

[0009] Preferably, the grinding device includes a fixed frame and symmetrically distributed second rotating shafts. The two ends of one of the second rotating shafts are rotatably connected to the inner walls of both sides of the fixed frame. A second motor is fixedly connected to one side of the fixed frame, and the output end of the second motor extends into the fixed frame and is fixedly connected to one of the second rotating shafts. Rollers are fixedly sleeved on the outer surface of the second rotating shafts, and a sanding belt is sleeved between the rollers. The sanding belt is located inside the fixed frame. The fixed frame has a U-shaped cross-section. Two support blocks are fixedly connected to both sides of the fixed frame. A fixed rod is fixedly connected between the support blocks on one side, and a threaded rod is rotatably connected between the support blocks on the other side. Slide grooves are provided on both sides of the fixed frame. Slider blocks are slidably connected to the inner walls of the slide grooves. When the threaded rod rotates, the sliders threadedly sleeved with it can move along the slide grooves due to the transmission effect of the threads. The sliders are rotatably connected to the two ends of the other second rotating shaft. The outer surface of the fixed rod is movably sleeved with one of the sliders, and the outer surface of the threaded rod is threadedly sleeved with the other slider. A knob is fixedly connected to the end of the threaded rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model can drive the first rotating plate to rotate through the first rotating shaft. When the first rotating plate rotates, the second rotating plate, which is symmetrically connected to its bottom surface, will move accordingly. Through the transmission and angle change of the second rotating plate, the clamping plate can make relative movement in the horizontal direction, thereby achieving the purpose of effectively clamping and fixing the metal parts to avoid displacement and other situations.

[0012] 2. This utility model can rotate the threaded rod, and due to the transmission effect of the thread, the slider that is threadedly connected to it can move along the slide groove, thereby driving the second rotating shaft to move and changing the distance between the two second rotating shafts, thus achieving the purpose of effectively adjusting the tightness of the sanding belt.

[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: Figure 1-3As shown, this utility model provides an adaptive polishing machine for metal parts processing, including a table 1. A polishing device 2 is fixedly connected to the center of the top surface of the table 1, and clamping devices 3 are fixedly connected to both sides of the top surface of the table 1. The clamping devices 3 include protective shells 301 that are symmetrically fixedly connected. A first rotating shaft 302 is movably passed through the lower end of the protective shell 301. A sprocket 303 is fixedly connected to the bottom end of the first rotating shaft 302. A chain 304 is meshed between the sprockets 303. A first motor 305 is fixedly connected to the inner wall of the table 1. The output end of the first motor 305 is fixedly connected to one of the sprockets 303. The first rotating shaft 302 is fixedly connected to the top of the first rotating plate 306. When the first motor 305 starts to rotate, the sprocket 303 connected to it rotates accordingly. Through the transmission of the chain 304, it drives another sprocket 303 to rotate synchronously. As the sprocket 303 rotates, the first rotating shaft 302 also rotates synchronously, thereby driving the top of the first rotating plate 306 to rotate. The bottom surface of the first rotating plate 306 is symmetrically rotatably connected to the second rotating plate 307. A fixing block 308 is rotatably connected to one side of the second rotating plate 307. A clamping plate 309 is fixedly connected to the side of the fixing block 308 away from the second rotating plate 307.

[0020] When the first rotating plate 306 rotates, the second rotating plate 307, which is symmetrically connected to its bottom surface, will move accordingly. Through the transmission and angle change of the second rotating plate 307, the clamping plate 309 can move relative to each other in the horizontal direction. One side of the opposite surface of the clamping plate 309 is arc-shaped. The lower end of the clamping plate 309 is symmetrically fixedly connected to the limiting block 310. The top surface of the protective shell 301 is symmetrically provided with two limiting grooves 311 that cooperate with the limiting block 310. The limiting block 310 slides in the inner wall of the limiting groove 311, which can ensure that the clamping plate 309 moves along a specific trajectory during the movement. The top surface of the protective shell 301 is symmetrically provided with a through groove 312 that cooperates with the clamping plate 309. The clamping plate 309 slides in the through groove 312, which also plays a guiding role in the movement of the clamping plate 309, and can effectively clamp and fix the metal parts to avoid displacement and other situations.

[0021] The grinding device 2 includes a fixed frame 20 and symmetrically distributed second rotating shafts 21. The fixed frame 20 is located between the protective shells 301. The two ends of one of the second rotating shafts 21 are rotatably connected to the inner walls on both sides of the fixed frame 20. A second motor 201 is fixedly connected to one side of the fixed frame 20. The output end of the second motor 201 extends into the fixed frame 20 and is fixedly connected to one of the second rotating shafts 21. A roller 22 is fixedly sleeved on the outer surface of the second rotating shaft 21. When the second motor 201 is started, it will drive the second rotating shaft 21 connected to it to rotate. Since the rollers 22 are fixedly sleeved on the outer surfaces of the two second rotating shafts 21, the rollers 22 also rotate synchronously with the rotation of the second rotating shafts 21, thereby driving the sanding belt 23 to perform a cyclical rotational motion within the fixed frame 20. The sanding belt 23 is sleeved between the rollers 22.

[0022] The sanding belt 23 is located inside the fixed frame 20. The high-speed rotation of the sanding belt 23 can perform grinding and polishing operations on the surface of the metal parts fixed by the clamping device 3. The fixed frame 20 has a U-shaped cross-section. Two support blocks 24 are fixedly connected to both sides of the fixed frame 20. A fixed rod 25 is fixedly connected between the support blocks 24 on one side, and a threaded rod 28 is rotatably connected between the support blocks 24 on the other side. Slide grooves 27 are provided on both sides of the fixed frame 20. A slider 26 is slidably connected to the inner wall of the slide groove 27. The outer surface of the slider 26 is in contact with the inner wall of the slide groove 27.

[0023] The sliders 26 are rotatably connected to both ends of another second rotating shaft 21. The outer surface of the fixed rod 25 is movably sleeved with one of the sliders 26, and the outer surface of the threaded rod 28 is threadedly sleeved with the other slider 26. A knob 29 is fixedly connected to the end of the threaded rod 28. When the knob 29 at the end of the threaded rod 28 is rotated, the threaded rod 28 rotates. Due to the transmission action of the thread, the slider 26 that is threadedly sleeved with it can move along the slide groove 27, thereby driving the second rotating shaft 21 to move. By changing the distance between the two second rotating shafts 21, the tightness of the sanding belt 23 can be effectively adjusted.

[0024] Working principle: First, place the metal part on the outer surface of the sanding belt 23, and place both ends of the metal part between the clamping plates 309. When the first motor 305 starts to rotate, the sprocket 303 connected to it rotates accordingly. Through the transmission of the chain 304, it drives another sprocket 303 to rotate synchronously. As the sprocket 303 rotates, the first rotating shaft 302 also rotates synchronously, thereby driving the first rotating plate 306 at the top to rotate. When the first rotating plate 306 rotates, the second rotating plate 307 symmetrically connected to its bottom surface will move accordingly. Through the transmission and angle change of the second rotating plate 307, the clamping plate 309 can move relative to each other in the horizontal direction, which can clamp the metal part placed on the table 1. The limiting block 310 slides in the inner wall of the limiting groove 311, which can ensure that the clamping plate 309 moves along a specific trajectory during the movement. The clamping plate 309 slides in the through groove 312, which also plays a guiding role in the movement of the clamping plate 309, thereby achieving the purpose of effectively clamping and fixing the metal part to avoid deviation and other situations.

[0025] When the second motor 201 starts, it drives the second rotating shaft 21 connected to it to rotate. Since the outer surfaces of the two second rotating shafts 21 are fixedly sleeved with rollers 22, as the second rotating shafts 21 rotate, the rollers 22 also rotate synchronously, thereby driving the sanding belt 23 to rotate in a circular motion within the fixed frame 20. The high-speed rotation of the sanding belt 23 can perform grinding and polishing operations on the surface of the metal parts fixed by the clamping device 3. When the knob 29 at the end of the threaded rod 28 is turned, the threaded rod 28 rotates. Due to the transmission action of the thread, the slider 26 that is threadedly sleeved with it can move along the slide groove 27, thereby driving the second rotating shaft 21 to move and changing the distance between the two second rotating shafts 21, thereby achieving the purpose of effectively adjusting the tightness of the sanding belt 23.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
