[0002] A polishing machine is a type of mechanical equipment widely used for surface treatment of materials such as metals, wood, and plastics. It uses a high-speed rotating polishing wheel or grinding disc to grind and polish workpieces, achieving the effect of removing burrs and improving surface smoothness. Polishing machines play an important role in industrial production, automotive repair, furniture manufacturing, and other fields, significantly improving processing efficiency and product quality.

[0003] Polishing machines generate high-speed, hot debris during the polishing process. This debris easily scatters in all directions, polluting the working environment and potentially injuring the user. Therefore, most polishing machines are now equipped with protective measures. However, traditional polishing machines are typically equipped with fixed protective covers. With this type of protection, the contact angle, pressure, and rotation speed between the polishing wheel and the workpiece vary, resulting in significant differences in the direction and range of debris splashing. Furthermore, the splash angle changes with the polishing angle. Consequently, fixed protective covers cannot fully cover all possible splash directions, limiting their protective effectiveness.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0019] This embodiment mainly describes the structure of the polishing machine, as follows: A polishing machine with an adjustable-angle splash guard, combined with... Figures 1-3 As shown, it includes: a base 1; a motor 2 fixedly mounted on the base 1; a polishing wheel 3 rotatably mounted on the base 1, the output end of the motor 2 being fixed to the polishing wheel 3 to drive the polishing wheel 3 to rotate for polishing; it also includes: a first fixed seat 6 fixedly mounted on the base 1; a fixed cover 4 fixedly mounted on the first fixed seat 6, the fixed cover 4 covering the rear half of the polishing wheel 3; a movable cover 5 rotatably mounted on the fixed cover 4, the rotation of the movable cover 5 changing the protection range of the polishing wheel 3, thereby realizing the adjustment of the polishing wheel 3 from partial coverage to complete coverage; the movable cover 5... A slot 8 is provided on the side, and the slot 8 is arranged in a circle around the pivot of the movable cover 5; a plug rod 9 is slidably installed on the fixed cover 4, and the plug rod 9 is inserted into the slot 8 to restrict the relative position between the movable cover 5 and the fixed cover 4. The end of the plug rod 9 is provided with a tapered surface 19, which is used to realize the smooth cooperation between the plug rod 9 and the slot 8; a first return spring 10 is fixedly installed between the plug rod 9 and the fixed cover 4, and the first return spring 10 is sleeved on the plug rod 9. The first return spring 10 is used to apply force between the plug rod 9 and the slot 8 to improve the stability of the cooperation between the two.

[0020] The method of using this polishing machine is as follows: First, start the motor 2 to drive the polishing wheel 3 to rotate. Before polishing, the user pulls the insert rod 9 outward to disengage it from the slot 8. At this time, the movable cover 5 can rotate freely and be adjusted to cover most of the area of ​​the polishing wheel 3, leaving only the necessary working space to meet the polishing operation requirements. After completion, release the insert rod 9. Under the action of the first return spring 10, the insert rod 9 automatically springs back and locks into the corresponding slot 8, thereby locking the position of the movable cover 5.

[0021] During polishing, the user holds the workpiece to be polished in one hand and inserts it into the protective space formed by the movable cover 5 and the fixed cover 4, allowing it to contact the rotating polishing wheel 3 for polishing. The other hand holds the movable cover 5. When the polishing angle of the workpiece needs to be adjusted, the user simply applies an appropriate rotational force to the movable cover 5. At this time, the slot 8, through the conical surface 19, exerts a squeezing effect on the insertion rod 9, causing it to overcome the elasticity of the first return spring 10 and temporarily disengage from the slot 8. As the movable cover 5 continues to rotate, when the insertion rod 9 moves to the next corresponding slot 8 position, the first return spring 10 pushes the insertion rod 9 to re-engage and lock, thus achieving a phased adjustment of the position of the movable cover 5. Therefore, during the polishing process, the user can flexibly and conveniently adjust the protective range of the movable cover 5 according to actual operational needs, ensuring it always maintains an optimal match with the current polishing angle. Simultaneously, the movable cover 5 remains stably locked in each adjustment position, ensuring both protective effectiveness and improved operational safety and convenience.

[0022] Combination Figure 1 and Figure 4 As shown, the polishing machine also includes: a connecting block 11 fixedly installed on the first fixed base 6; a second fixed base 12 fixedly installed on the connecting block 11; a movable plate 13 slidably installed on the second fixed base 12, the movable plate 13 being vertically displaced; and a second return spring 14 fixedly installed between the movable plate 13 and the second fixed base 12, the second return spring 14 being sleeved on the sliding shaft of the movable plate 13.

[0023] When polishing a workpiece, the workpiece can be placed on the movable plate 13, which will provide stable auxiliary support for the workpiece. The mechanical vibration generated during the polishing process will be effectively absorbed and attenuated by the elastic buffering effect of the second return spring 14. On the one hand, this can reduce the fatigue of users working for a long time, and on the other hand, it will ensure that the workpiece and the polishing wheel 3 maintain a stable contact state, thereby improving the stability of the processing process and the uniformity of polishing quality.

[0024] Combination Figure 1 , Figure 4 and Figure 5As shown, the polishing machine also includes: a corner plate 15 rotatably mounted on the movable plate 13; and a torsion spring 16 fixedly mounted between the corner plate 15 and the movable plate 13, the torsion spring 16 being sleeved on the rotating shaft of the corner plate 15.

[0025] After the workpiece is placed on the movable plate 13, when the operator adjusts the workpiece processing angle, the corner plate 15 will rotate with the workpiece to ensure that the movable plate 13 always maintains the best contact state with the workpiece, so as to maintain the stable shock absorption and buffering effect of the movable plate 13 and improve the use effect of the movable plate 13. After the workpiece is separated from the corner plate 15, the torsion spring 16 rotates the corner plate 15 to reset, preparing for the next processing.

[0026] Combination Figures 1-5 As shown, this polishing machine also includes: a baffle 7 fixedly installed at the end of the movable cover 5, which has a groove for the polishing wheel 3 to pass through. The baffle 7 is used to prevent debris generated during processing from splashing into the interior of the movable cover 5, thereby reducing the difficulty of subsequent cleaning; a soft pad 17 fixedly installed on the corner plate 15, which is used to protect the workpiece and prevent the workpiece from contacting and wearing with the corner plate 15 when adjusting the polishing position; and a scale ring 18 fixedly installed on the movable cover 5, which is arranged around the slot 8 to indicate each slot. The angle corresponding to 8 allows users to precisely control the rotation angle of the movable cover 5 by observing the scale ring 18, meeting different polishing needs. The scraper 20, fixedly installed on the movable cover 5, contacts the inner wall of the fixed cover 4. As the movable cover 5 rotates, the scraper 20 moves accordingly, thereby cleaning the debris inside the fixed cover 4 and improving the ease of use of this polishing machine. The light strip 21, fixedly installed at the lower end of the fixed cover 4, provides a good visual environment and facilitates the processing of the workpiece.
