[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-6 , an outer protective cover of a numerical control device, comprising a protective cover body 1 rotatably connected to both ends of a processing table of the numerical control device, a pair of symmetrical driving rails 3 are fixedly connected to the bottom end of the processing table of the numerical control device, a transmission assembly is arranged inside the driving rail 3, the transmission assembly comprises a screw shaft 8 rotatably connected to the inside of the driving rail 3, a nut block 9 threadedly connected to the surface of the screw shaft 8 and a driving rod 2 rotatably connected to the top of the nut block 9, an outer side wall of the protective cover body 1 is fixedly connected to a hinged channel steel, and the hinged channel steel is rotatably connected to one end of the driving rod 2;

[0026] It should be noted that the rotation of the screw shaft 8 causes the nut block 9 to drive one end of the transmission rod 2 to move, and then the other end of the transmission rod 2 drives the protective cover body 1 to rotate, thereby realizing the automatic opening and closing function of the protective cover body 1, thereby eliminating the need for manual opening and closing by staff and automatically realizing the locking function of the protective cover body 1, thereby improving the opening and closing efficiency of the protective cover body 1.

[0027] A driving assembly is provided at the bottom end of the CNC equipment processing table, and the driving assembly includes a motor box 5 fixedly connected to the bottom end of the CNC equipment processing table, a steering motor 13 installed inside the motor box 5, a linkage shaft 4 rotatably connected to the side wall of the motor box 5, and a driven bevel gear 10 fixedly connected to one end of the linkage shaft 4, one end of the screw shaft 8 passes through the side wall of the driving slide rail 3, the other end of the linkage shaft 4 is fixedly connected to one end of the screw shaft 8, and one end of the output shaft of the steering motor 13 is fixedly connected to an active bevel gear 12 meshing with the driven bevel gear 10;

[0028] It should be noted that: when the steering motor 13 is turned on, the steering motor 13 drives the active bevel gear 12 to rotate, and then drives the driven bevel gear 10 to rotate, and then drives the linkage shaft 4 to rotate, and the linkage shaft 4 drives the screw shaft 8 to rotate, providing driving force for the rotation of the screw shaft 8.

[0029] The inner wall of the protective cover body 1 is fixedly connected with symmetrically arranged L-shaped slide rails 7, and a wiping block 6 for wiping dust and debris is arranged between the L-shaped slide rails 7, and a replaceable wiping cotton 14 is sleeved on the surface of the wiping block 6;

[0030] It should be noted that: the L-shaped slide rail 7 cooperates with the wiping block 6. When the protective cover body 1 rotates and tilts to a certain angle, the wiping block 6 slides to the bottom end of the protective cover body 1 under the action of its own gravity, realizing the automatic wiping and cleaning function of part of the inner wall of the protective cover body 1, thereby reducing the workload of the staff.

[0031] Telescopic grooves are provided at both end faces of the wiping block 6, in which a sliding shaft 15 is slidably connected to the L-shaped slide rail 7, a compression spring 11 is fixedly connected between the sliding shaft 15 and the inner wall of the telescopic groove, and a steering groove is provided at one end face of the sliding shaft 15, in which a ball 16 is rollingly connected.

[0032] It should be noted that: by moving the wiping block 6 laterally, the compression spring 11 can be squeezed to make the sliding shaft 15 at the other end disengage from the L-shaped slide rail 7, so that the wiping block 6 can be disassembled to facilitate replacement and cleaning of the wiping cotton 14.

[0033] The steering motor 13 is a prior art, and its model is JB5274-91. It can realize the function of driving the active bevel gear 12 to rotate, and will not be described in detail here.

[0034] When the utility model is in use, when the protective cover body 1 needs to be opened, the steering motor 13 is turned on, the steering motor 13 drives the active bevel gear 12 to rotate, and then drives the driven bevel gear 10 to rotate, and the driven bevel gear 10 drives the screw shaft 8 to rotate through the linkage shaft 4, so that the nut block 9 drives one end of the transmission rod 2 to move, so that the transmission rod 2 drives the protective cover body 1 to rotate, and the automatic opening and closing function of the protective cover body 1 is realized, and the manual opening and closing of the staff is not required, which reduces the workload of the staff, and the locking function of the protective cover body 1 is automatically realized, thereby improving the opening and closing efficiency of the protective cover body 1;

[0035] When the protective cover body 1 rotates and tilts to a certain angle, the wiping block 6 slides to the bottom end of the protective cover body 1 under its own gravity, realizing the automatic wiping and cleaning function of part of the inner wall of the protective cover body 1, thereby further reducing the workload of the staff;

[0036] When the wiping cotton 14 needs to be disassembled and cleaned, the wiping block 6 is moved laterally, thereby squeezing the compression spring 11, so that the sliding shaft 15 at the other end is separated from the L-shaped slide rail 7, thereby realizing the disassembly function of the wiping block 6, and facilitating the replacement and cleaning of the wiping cotton 14;

[0037] When it is necessary to close the protective cover body 1, the steering motor 13 can be turned on first to make it rotate in the opposite direction (compared to the rotation direction of the steering motor 13 when the protective cover body 1 is opened), so that the protective cover body 1 is rotated to an inclination angle smaller than the wiping block 6 can slide under its own gravity, and then the steering motor 13 is turned off. At this time, the staff needs to manually slide the wiping block 6 to reset it, and then turn on the steering motor 13 again to reset the protective cover body 1.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
