DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The grinding sandpaper replacement device is an efficient and intelligent mechanical component used to automatically replace sandpaper to optimize the grinding and polishing process. The grinding sandpaper replacement device provides an efficient, safe and reliable sandpaper automatic replacement solution for the grinding and polishing robot. Through the analysis of structural composition, working principle, technical characteristics, application scope, existing technology comparison, development trend, operation precautions and future prospects, it can be seen that the device has significant advantages in improving production efficiency, reducing labor intensity, and reducing the risk of occupational diseases.

[0019] See also Figure 1-Figure 4 As shown, the present embodiment provides a grinding sandpaper replacement device, including a sandpaper replacement device body 1, a pressing assembly 2 is arranged inside the sandpaper replacement device body 1, and the pressing assembly 2 is used to limit the displacement of the grinding sandpaper. The pressing assembly 2 includes a trapezoidal block 22 and a sliding rod 23. Since the sandpaper of the grinding sandpaper replacement device is frequently replaced mechanically, it is inconvenient to fix the sandpaper. The sandpaper is easy to fall off the grinding sandpaper replacement device. When the sandpaper is replaced mechanically, displacement may occur, resulting in the sandpaper installation offset, affecting the grinding effect, reducing work efficiency, and low practicality. Therefore, the details are as follows: Press the trapezoidal block 22 downward to drive the sliding rod 23 to slide on both sides of the trapezoidal block 22, control the displacement of the grinding sandpaper above the sandpaper replacement device body 1, prevent the sandpaper from falling from above the sandpaper replacement device body 1, or the installation position is deviated, affecting the grinding work, and improving practicality.

[0020] The improvement of this embodiment is that:

[0021] When the grinding machine presses down the pressing block 21, the sliding rod 23 slides on both sides of the trapezoidal block 22, driving the support plate 25 to move horizontally above the sandpaper changing device body 1, loosening the fixation of the sandpaper, and the first spring 222 rebounds to drive the support plate 25 to reset, and the pressing plate 27 fits against the top of the sandpaper to squeeze, controlling the remaining sandpaper from being displaced, preventing the sandpaper installation displacement from deviation, and improving practicality.

[0022] In order to enable the pressing component 2 to press and limit the sandpaper, the interior of the sandpaper changing device body 1 is a hollow structure, and a pressing block 21 is slidably connected to the inner wall of the sandpaper changing device body 1, and a trapezoidal block 22 is fixedly connected to the lower surface of the pressing block 21. Sliding grooves 221 are symmetrically provided on both sides of the trapezoidal block 22, and the sliding grooves 221 are "T"-shaped. The inner walls of the two sliding grooves 221 are slidably connected with sliding rods 23, and the ends of the sliding rods 23 extending out of the outer wall of the sandpaper changing device body 1 are fixedly connected with a fixing plate 24, and the outer side of the fixing plate 24 is fixedly connected with a supporting plate 25. The pressing block 21 slides downward under pressure, and the pressing block 21 drives the trapezoidal block 22 below to squeeze the first spring 222 downward. In the process of the trapezoidal block 22 moving downward, the sliding rods 23 on both sides of the trapezoidal block 22 are driven to slide toward the outer wall of the sandpaper changing device body 1, and the sliding rods 23 drive the fixed plate 24 and the supporting plate 25 at the end to leave the upper part of the sandpaper changing device body 1. There is no obstruction above the sandpaper. At this time, the sandpaper can be directly pressed down to replace.

[0023] Considering that the trapezoidal block 22 needs to be reset, a first spring 222 is fixedly connected to the lower surface of the trapezoidal block 22, and the lower end of the first spring 222 is fixedly connected to the inner cavity of the sandpaper changing device body 1. When the pressing block 21 loses pressure, the elastic force of the first spring 222 below loses pressure, driving the trapezoidal block 22 to move upward.

[0024] Taking into account the need to fit the remaining sandpaper for pressing and controlling the displacement, a fixing rod 26 is fixedly connected to the lower surface of the support plate 25, and an inner rod 261 is slidably connected to the inner wall of the fixing rod 26. A pressing plate 27 is fixedly connected to the lower end of the inner rod 261, and a second spring 28 is fixedly connected to the upper surface of the pressing plate 27. The second spring 28 is movably sleeved on the outer wall of the fixing rod 26, and the upper end of the second spring 28 is fixedly connected to the lower surface of the support plate 25. The pressing plate 27 drives the inner rod 261 to slide on the inner wall of the fixing rod 26. The elasticity of the second spring 28 drives the pressing plate 27 below to fit the sandpaper and squeeze it, thereby controlling the displacement of the sandpaper.

[0025] Taking into account that the pressing plate 27 is inconvenient to press along the sandpaper, the lower surface of the support plate 25 is fixedly connected to a sloped panel 29, and the inner wall of the sloped panel 29 is slidably connected to an inner plate 291. The outer side of the inner plate 291 is fixedly connected to the outer side of the pressing plate 27, and the outer wall of the inner plate 291 is slidably matched with the inner wall of the sloped panel 29. The inner plate 291 is driven by the pressure of the sandpaper to move the pressing plate 27 upward. When the pressing plate 27 moves, it drives the inner plate 291 to slide on the inner wall of the sloped panel 29.

[0026] In summary, the working principle of this scheme is as follows:

[0027] When the sandpaper replacement device of the present invention is used, the sandpaper is placed above the main body 1 of the sandpaper replacement device, and the pressing plate 27 is pressed against the upper surface of the sandpaper. When the sandpaper of the grinder needs to be replaced, the waste sandpaper of the grinder is removed, the grinder is opened, and the grinder is moved to the top of the main body 1 of the sandpaper replacement device, and the pressing block 21 is slowly pressed down. The pressing block 21 slides downward under the pressure, and the pressing block 21 drives the trapezoidal block 22 below to squeeze the first spring 222 downward. In the process of the trapezoidal block 22 moving downward, the sliding rods 23 on both sides of the trapezoidal block 22 are driven to slide toward the outer wall of the main body 1 of the sandpaper replacement device, and the sliding rods 23 drive the fixed plate 24 and the supporting plate 25 at the end to leave the top of the sandpaper replacement device main body 1. At this time, there is no obstruction above the sandpaper, and the grinding The machine is directly pressed down, and the sandpaper is attached to the bottom of the grinder. After the sandpaper is replaced on the grinder, the grinder moves upward, the pressing block 21 loses pressure, and the elastic force of the first spring 222 below loses pressure drives the trapezoidal block 22 to move upward, and the trapezoidal block 22 drives the sliding rods 23 on both sides to slide along the sliding groove 221, and the sliding rods 23 drive the symmetrical supporting plates 25 to move in the opposite direction. The inner plate 291 is subjected to the pressure of the sandpaper to drive the pressing plate 27 to move upward. When the pressing plate 27 moves, it drives the inner plate 291 to slide on the inner wall of the inclined plate 29, and the pressing plate 27 drives the inner rod 261 to slide on the inner wall of the fixed rod 26. The elasticity of the second spring 28 drives the pressing plate 27 below to fit the sandpaper and squeeze, thereby controlling the displacement of the sandpaper and preventing the sandpaper from falling from the top of the sandpaper changing device body 1.
