DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-4The shown internal protection structure of the CNC machine tool transmission includes a base 1, a cover body 2 is arranged on the top of the base 1, and the inner walls on both sides of the cover body 2 are symmetrically fixedly connected with baffles 3 for blocking iron chips, and one side of the baffle 3 is provided with a blocking component 4 for blocking iron chips. The blocking component 4 includes a fixed block 401 arranged on one side of the baffle 3, a rubber block 402 is arranged on one side of the fixed block 401, a fixing component 5 for fixing the position of the fixed block 401 is arranged at the connection between the fixed block 401 and the baffle 3, and a supporting component 6 for supporting the fixed block 401 is arranged at the connection between the baffle 3 and the fixed block 401.

[0020] It should be noted that the cover body 2 is a steel plate protective cover of model VMC850E / 850B. When in use, the transmission system located on the top of the base 1 is protected by the cover body 2; the material of the baffle 3 is consistent with that of the cover body 2. When it is manufactured, it is fixed to the inner walls of the front and back of the cover body 2 by welding. The fixed block 401 and the rubber block 402 are fixed to one side of the baffle 3 by the fixing component 5, so that the side of the rubber block 402 away from the fixed block 401 is in contact with the base 1, so that the baffle 3, the fixed block 401 and the rubber block 402 are used to block the cover body 2 and the base 1, so as to prevent iron filings from flying into the interior of the cover body 2 and strengthen the protection of the transmission system on the top of the base 1; the rubber block 402 is made of rubber material, and will deform when it is squeezed, so as to fill and block the gap between the fixed blocks 401 on both sides and the base 1 through deformation, and drive the rubber block 402 to slide on the base 1 when the cover body 2 moves.

[0021] Specifically, the fixing component 5 includes a positioning block 501 which is centrally symmetrically fixedly connected to one side of the fixing block 401, a positioning groove 502 is centrally symmetrically opened on one side of the baffle 3, the positioning block 501 is inserted and connected inside the positioning groove 502, the cross-sections of the positioning block 501 and the positioning groove 502 are both set to be isosceles trapezoids, the inner wall of one side of the positioning groove 502 is fixedly connected with an adhesive layer 503, and the positioning block 501 is fixedly connected to one side of the adhesive layer 503.

[0022] It should be noted that the adhesive layer 503 is a colloid, which is used to fix the positioning block 501 and the positioning groove 502 when in use; the opened positioning groove 502 is adapted to the set positioning block 501, and through the trapezoidal design, it can avoid the positioning block 501 from shaking in the positioning groove 502, and avoid the deviation of the positions of the two when fixing the positioning block 501 and the positioning groove 502.

[0023] Furthermore, when the rubber block 402 is worn and needs to be replaced, hot water is poured on the adhesive layer 503 to soften the colloid, thereby facilitating the removal of the positioning block 501 from the inside of the positioning groove 502, and the fixing block 401 and the rubber block 402 are removed from one side of the baffle 3 through the positioning block 501, and then a new fixing block 401 and rubber block 402 are replaced, and the positioning block 501 on one side of the replaced fixing block 401 is coated with colloid, and is pressed into the positioning groove 502, and the positioning block 501 and the positioning groove 502 are fixed by the colloid, thereby fixing the fixing block 401 and the rubber block 402 by the positioning block 501 in a fixed position.

[0024] Specifically, the support assembly 6 includes a support block 602 centrally and symmetrically fixedly connected to one side of the fixing block 401 , a support groove 601 centrally and symmetrically opened on one side of the baffle 3 , and the support block 602 is inserted and connected inside the support groove 601 .

[0025] It should be noted that the support groove 601 is used to support the support block 602 on one side of the fixed block 401, so as to limit the moving distance of the support block 602 by the support groove 601. When the positioning block 501 on one side of the fixed block 401 is inserted into the positioning groove 502, the support block 602 on one side of the fixed block 401 is inserted into the interior of the support groove 601. When the inner wall of the bottom end of the support block 602 fits with the inner wall of the bottom end of the support groove 601, the support block 602 does not need to move downward, and the movement of the fixed block 401 and the positioning block 501 is limited by the support block 602 that limits the movement.

[0026] Specifically, a guide rail 7 is fixedly connected to the top of the base 1 in a symmetrical manner, a guide plate 8 is provided on the top of the guide rail 7 , and the guide plate 8 is fixedly connected to the inner wall of the bottom end of the cover body 2 .

[0027] It should be noted that when the cover body 2 moves, the cover body 2 slides on the guide rail 7 through the guide plate 8 .

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
