[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] Please see Figure 1-8 A grinding wheel box with a viewing window includes a box body 1 and a box door 2 to prevent grinding wheel debris from easily ejecting forward during sanding operations. The rear side of the box body 1 has a through hole 101 for the grinding machine spindle to pass through, and a connecting flange 102 is provided around the through hole 101. The connecting flange is used to fix the grinding wheel box to the slide of the surface grinder. In this solution, the grinding wheel box can also be fixedly connected to the slide of the surface grinder through other existing technologies, including but not limited to the connection using the connecting flange 102.

[0028] The top of the housing 1 has a waist-shaped hole 103 for the dressing tool of the grinding wheel dressing device to pass through;

[0029] The bottom and front end of the housing 1 are provided with openings, and the interior of the housing 1 is used to accommodate the grinding wheel;

[0030] The right side of the door 2 is rotatably connected to the right side of the box body 1 via a hinge 3; the left side of the door 2 is movably connected to the left side of the box body 1 via a door lock 4.

[0031] The box door 2 is also provided with a viewing window 5, and a transparent glass plate 501 is installed inside the viewing window 5. The viewing window 5 is used to observe the contact between the dressing tool of the grinding wheel dressing device and the grinding wheel.

[0032] In this solution, during sanding operations, the cutting tool will grind away the uneven parts of the grinding wheel, and the scraped debris will be ejected, which makes the transparent glass plate 501 easily scratched by the debris, resulting in unclear observation. In order to facilitate the replacement of the transparent glass plate 501, a glass plate receiving structure 6 is provided on the rear side of the door 2 corresponding to the viewing window 5. The receiving structure 6 has a vertically opened receiving groove 601 for receiving the transparent glass plate 501. The top of the receiving groove 601 is open, and a rectangular opening groove 602 is opened at the rear end of the receiving groove 601 to avoid obstructing the view.

[0033] This solution uses the glass plate receiving structure 6 to movably install the transparent glass plate 501, so that the transparent glass plate 501 can be replaced in time after the transparent glass surface is worn.

[0034] In this design, the grinding wheel box vibrates during grinding, which can cause the transparent glass plate 501 to collide with the receiving structure 6, potentially leading to its breakage. Therefore, in this design, rubber layers 502 are bonded to both the front and back surfaces of the transparent glass plate 501, and the sides of the transparent glass plate 501 with the rubber layers 502 are tightly fitted with the receiving groove 601. This means that when the transparent glass plate 501 is inserted into the receiving structure 6, the rubber layers 502 are compressed by the receiving groove 601, making the transparent glass plate 501 less prone to shaking, thereby reducing the impact with the receiving structure 6 and minimizing the possibility of breakage.

[0035] In this design, the transparent glass plate 501 can also be a convex lens; the advantage of using a convex lens is that it can magnify the virtual image at the contact point between the cutting tool and the grinding wheel, thus facilitating better observation; it is worth noting that...

[0036] like Figure 9 As shown, in some embodiments of this solution, the transparent glass plate 501 is square in shape, and the center of the transparent glass plate 501 is a convex mirror;

[0037] When using this utility model, the operator can observe the contact between the cutting tool and the grinding wheel through the viewing window 5, thereby gaining a more intuitive understanding of the sanding operation. At the same time, after the surface of the transparent glass plate 501 is worn, the box door 2 can be opened to pull out the transparent glass plate 501 from the top of the glass plate receiving structure 6 for replacement.
