[0043] The grinding device 100 claimed in the present application is used to grind the inner wall 201 of the guide rail 200 to remove burrs. Here, the guide rail 200 is a guide rail of a dishwasher rack. Of course, for those skilled in the art, the guide rail 200 can also be a guide rail of a refrigerator drawer or a guide rail used in other different scenarios.

[0044] like Figure 1 , Figure 2 As shown, the grinding device 100 provided in an embodiment of the present application includes an operating table 10, a gantry 20, a movable base 30 and a grinder 40. The gantry 20 is fixedly installed on the operating table 10; the movable base 30 is arranged through the gantry 20 and is slidably connected to the operating table 10, the movable base 30 is used to carry the guide rail 200, and the movable base 30 can drive the guide rail 200 to pass through the gantry 20; the grinder 40 is arranged at an angle above the movable base 30 and is rotatably connected to the gantry 20, the grinder 40 is used to grind the inner wall 201 of the guide rail 200 on the movable base 30, and the installation position of the grinder 40 on the gantry 20 can remain unchanged or be adjusted. Here, the grinder 40 is configured as an electric grinder. When the installation position of the grinder 40 on the gantry 20 remains unchanged, the grinder 40 can grind the guide rail 200 when passing through the gantry 20. Of course, the structural composition of the electric grinder and the working principle of how to grind the inner wall 201 of the guide rail 200 during operation can adopt the existing conventional methods, which will not be elaborated here.

[0045] It can be understood that the gantry 20 is used to raise the grinder 40, so that the movable base 30 drives the guide rail 200 to grind the guide rail 200 when passing through the grinder 40. In this way, the grinding of the guide rail 200 can be automated, which has the effect of improving efficiency, reducing costs, and ensuring the grinding quality; in addition, since the installation position of the grinder 40 on the gantry 20 can be adjusted, the grinder 40 can contact the inner wall 201 of the guide rail 200 at different angles, so that the grinding device 100 can be suitable for grinding different types of guide rails 200, which has the effect of expanding the scope of application.

[0046] It should be noted that when the grinding device 100 of the present application is working, the movable base 30 is used to drive the guide rail 200 to pass through the gantry 20, and the fixed grinder 40 is used for grinding. This not only makes it easier to assemble the grinder 40 to the gantry 20 and facilitates the control of the grinding device 100 when it is working, but also simplifies the structural composition of the grinding device 100.

[0047] like Figure 1 As shown, the number of the gantries 20 and the number of the grinders 40 are both configured as two, and the two grinders 40 are arranged on the two gantries 20 in a staggered manner, and the two grinders 40 can grind the inner wall 201 of the guide rail 200 on the movable base 30 at the same time. That is to say, when the grinding device 100 is working, two grinders 40 can be used to grind two parts of the inner wall 201 of the guide rail 200 at the same time, which has the effect of further improving the grinding efficiency. Here, the two grinders 40 are arranged in a staggered manner, specifically, the two grinders 40 are arranged on both sides of the movable base 30 in a left-right symmetrical manner, so that when the grinding device 100 is working, the inner wall 201 of the folding position on the left and right sides of the guide rail 200 can be grinded at the same time. Of course, in other embodiments, the number of grinders 40 can also be configured as one, three, or even more.

[0048] like Figure 2As shown, the movable base 30 includes a base body 31 and two movable stop blocks 32. The base body 31 is used to carry the guide rail 200. The movable stop blocks 32 are detachably connected to the base body 31 and are used to limit the guide rail 200 carried by the base body 31 to the base body 31. The installation position of at least one movable stop block 32 on the base body 31 can be adjusted. In this way, when the movable base 30 is used to carry the guide rail 200, the installation position of the movable stop block 32 on the base body 31 can be adjusted to achieve the limit of the guide rail 200 assembled on the base body 31, so that the movable base 30 can drive the guide rail 200 to enter the gantry 20 together. Here, the two movable limit blocks 32 are respectively provided with a first waist-shaped hole 321, and bolts (not shown) passing through the first waist-shaped hole 321 and screwed to the base body 31 are used to realize the assembly limit of the movable limit block 32 on the base body 31. In this process, the structural characteristics of the first waist-shaped hole 321 can be used to adjust the installation position of the movable limit block 32 on the base body 31.

[0049] like Figure 1 As shown, the grinding device 100 also includes a slide 301, which is fixedly mounted on the operating table 10 and slidably connected to the movable base 30, so that the movable base 30 can be guided by the sliding of the slide 301 on the operating table 10, which can facilitate the driving of the movable base 30 to slide on the operating table 10. Here, the slide 301 is arranged through the gantry 20, so that the movable base 30 can drive the guide rail 200 to slide on the slide 301 and pass through the grinder 40.

[0050] like Figure 1 As shown, the grinding device 100 also includes a telescopic driving member 302, which is in transmission connection with the movable base 30, and the telescopic driving member 302 is used to drive the movable base 30 to slide on the operating table 10.

Here, the telescopic driving member 302 is configured as a telescopic cylinder or a motor, and the motor can drive the movable base 30 to slide on the slide 301 through a screw nut assembly, which will not be elaborated here.

[0051] like Figure 1 , Figure 3 As shown, the grinding device 100 further includes an adapter block 50, which is rotatably connected to the gantry 20 and fixedly connected to the grinder 40; wherein the installation position of the adapter block 50 on the gantry 20 can be adjusted. In other words, the gantry 20 uses the adapter block 50 to carry the grinder 40. Here, the adapter block 50 can clamp the grinder 40 in a tight fit manner and realize the assembly connection of the grinder 40 on the adapter block 50.

[0052] like Figure 1 , Figure 3 As shown, a positioning rod 51 is fixedly connected to the adapter block 50, and the positioning rod 51 passes through the gantry 20 and abuts against the gantry 20; wherein, a limiting block 21 is slidably connected to the gantry 20, and the limiting block 21 can push the positioning rod 51 to move relative to the gantry 20, and adjust the installation position of the adapter block 50 on the gantry 20. In this way, the abutment between the positioning rod 51 and the limiting block 21 can be used to locate the installation position of the adapter block 50 on the gantry 20. In addition, the positioning rod 51 can be pushed when the limiting block 21 is adjusted on the gantry 20, so that the installation position of the adapter block 50 on the gantry 20 can be adjusted, thereby facilitating the adjustment of the installation position of the grinder 40 on the gantry 20. Here, the positioning rod 51 is connected to the adapter block 50 in a threaded manner, and the adjustment of the adapter block 50 for clamping the grinder 40 is realized; a second waist-shaped hole 211 is opened on the limit block 21, and a bolt (not shown) passing through the second waist-shaped hole 211 and screwed to the gantry 20 is used to realize the assembly limit of the limit block 21 on the gantry 20. In this process, the structural characteristics of the second waist-shaped hole 211 can be used to realize the adjustment of the installation position of the limit block 21 on the gantry 20.

[0053] like Figure 3 As shown, the positioning rod 51 has a positioning head 511, which is arranged on one end of the positioning rod 51 away from the adapter block 50; and the positioning head 511 is in contact with the limit block 21. In this way, the contact between the positioning head 511 on the positioning rod 51 and the limit block 21 can be increased, so that the stability of the limit block 21 when limiting the positioning rod 51 can be improved, and the stability of the grinder 40 after the position adjustment on the gantry 20 can be improved, so as to meet the use requirements of grinding and deburring the guide rail 200.

[0054] like Figure 1 , Figure 3 As shown, the grinding device 100 further includes a pressing member 60; when the movable base 30 drives the guide rail 200 to pass through the gantry 20, the pressing member 60 can press the guide rail 200 to limit the guide rail 200 to the movable base 30. In this way, the stability of the guide rail 200 on the movable base 30 can be improved when the movable base 30 drives the guide rail 200 to pass through the gantry 20, so as to meet the use requirements of the grinder 40 for grinding the inner wall 201 of the guide rail 200.

[0055] like Figure 3As shown, the pressing piece 60 is configured as a bearing 61, and the bearing 61 is rotatably mounted on the gantry 20. In this way, on the one hand, the pressing piece 60 can be made of local materials, which has the effect of reducing costs; on the other hand, the friction force when the bearing 61 contacts the guide rail 200 can be rolling friction, which can reduce the resistance of the bearing 61 to the guide rail 200 when it follows the movable base 30 to slide on the operating table 10, and avoid damage to the guide rail 200. Here, the number of bearings 61 is two, and the two bearings 61 can press and limit the left and right sides of the guide rail 200.

[0056] In summary, when the grinding device 100 of the present application is grinding the inner wall 201 of the guide rail 200, the movable base 30 can drive the guide rail 200 to slide on the operating table 10, so that when the guide rail 200 passes through the gantry 20, the grinder 40 can grind the inner wall 201 of the guide rail 200. In this way, the automation of the grinding of the guide rail 200 can be realized, which has the effects of improving efficiency, reducing costs, and ensuring the grinding quality.
