[0002] The bed shield is used to protect the machine tool, and it can protect the surface of the machine tool from corrosion and damage by the outside world. There are many types of the bed shield, including the organ shield, the steel plate shield, the screw rod shield, the round shield, the square shield, the polygonal shield, and the like. The organ shield, the screw rod shield, the helmet shield, the roller shutter shield, and the like can be classified into the organ shield, the screw rod shield, the helmet shield, and the roller shutter shield.

[0003] However, if the parts fall and directly hit the surface of the shield during the maintenance or the machining of the product, the deformation of the shield can occur. In addition, the existing shield is usually removed and then the damaged shield plate is replaced during the maintenance, which is time-consuming and laborious, and the maintenance efficiency of the shield is reduced.

[0004] In addition, the gap between the shield plates of the existing shield is usually reduced to block the cutting fluid. Although the blocking effect is achieved, the blocking effect is not good, and the cutting fluid can still contact the guide rail. The surface of the guide rail is lubricated with oil, and the cutting fluid can gradually wash away the oil, thereby reducing the smoothness of the guide rail and the accuracy of the machine tool.

The inner cavities of the positioning grooves are slidably connected with sliding blocks. One side of the sliding block is fixedly connected with a connecting block. The surface of the connecting block is provided with a through hole.

[0008] A clamping groove is arranged on the surface of the connecting shell and the fixing frame. The bottom of the connecting shell and the fixing frame is provided with a positioning bolt. One side of the connecting shell and the fixing frame is fixedly connected with a sealing strip. One side of the mounting shell and the connecting shell is fixedly connected with a cleaning strip. The surface of the connecting shell and the fixing frame is provided with a flow guide groove. The surface of the mounting shell and the fixing frame is provided with a mounting plate.

[0009] Preferably, there are several connecting shells, the volume of the connecting shells decreases sequentially towards the side away from the mounting shell, and the inner wall of one connecting shell is slidably connected to the surface of the other connecting shell.

[0010] Preferably, the sliding block is a cuboid design, with one side of the connecting shell surface slidably connected to the inner wall of the mounting shell.

[0011] Preferably, the other end of the positioning bolt extends into the interior of the slot and is threadedly connected to the inner wall of the through-hole, and the surface of the positioning bolt is threadedly connected to the inner wall of the through hole.

[0012] Preferably, the sealing strip is made of rubber, and the surface of the sealing strip is slidably connected to the inner wall of both the mounting shell and the connecting shell.

[0013] Preferably, the cleaning strip has a triangular cross-sectional shape, and the surface of the cleaning strip is slidably connected to the surfaces of the connecting shell and the fixing frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention allows for the direct removal and replacement of the damaged connecting shell through the cooperation of the positioning bolts and the connecting block, without the need to completely disassemble the protective cover. This not only makes the process more convenient but also improves replacement efficiency. Furthermore, the combination of the sealing strip, cleaning strip, and guide groove effectively blocks cutting fluid, reducing its entry into the protective cover and significantly enhancing its protection of the guide rail. This improves the cover's applicability and solves the problems of existing protective covers being inconvenient to maintain and having poor protective effects. Attached Figure Description
