AI Technical Summary
Existing machine tool protective covers generate a lot of noise during opening and closing and are prone to not closing properly due to inertia, posing a safety hazard.
The design employs a roller and guide rail rolling mechanism, combined with a limiting structure consisting of a limiting groove, a limiting spring, and a limiting block, to reduce friction noise and ensure that the protective door closes quickly and tightly.
It effectively reduces the noise when the protective cover door slides, ensures the tightness of the protective cover door when closed, and improves safety and user experience.

[0002] The main shaft of horizontal machine tool is parallel with worktable, and is in horizontal position, and the rotating speed is 12 levels, various cylindrical milling cutter, round piece milling cutter, angle milling cutter, profile milling cutter and face milling cutter can be used to process various planes, inclined planes, grooves and the like.In the cutting process, a large amount of waste will be produced, and the waste will be scattered everywhere.In order to avoid the waste from being scattered outside, a protective cover is arranged on the machine tool.
[0003] At present, the protective cover of machine tool is generally made of sheet metal part, and the left protective cover door and the right protective cover door are arranged in front of the protective cover and can be opened and closed by translation.The left and right protective cover doors are slidably installed on the guide rails, and a large noise will be generated when they slide along the guide rails.In the process of opening and closing, the protective cover doors are prone to be not tightly closed due to inertia, and the direct processing in this state has safety hazards, and the overall effect is not good. SUMMARY
[0004] In order to solve the above problems, the utility model provides a noise reduction protective cover, which can reduce noise and quickly close the protective cover door.
[0005] Therefore, the technical scheme of the utility model is as follows: a noise reduction protective cover, which comprises a protective cover body, the protective cover body is assembled by sheet metal panels, movable left and right protective cover doors are arranged on the front side of the protective cover body, and upper and lower guide rails are arranged on the front side of the protective cover body.
[0006] On the basis of the above scheme and as a preferred scheme of the above scheme, grooves are arranged on the upper and lower guide rails, and a plurality of first rollers arranged vertically and second rollers arranged horizontally are arranged on the upper and lower sides of the left and right protective cover doors, which are in rolling contact with the groove bottom and the two side groove walls.
[0007] On the basis of the above scheme and as a preferred scheme of the above scheme, the limiting rods are in the form of doors, and an insertion block is arranged below the limiting groove, which can be inserted into the limiting rod.
[0008] On the basis of the above scheme and as a preferred scheme of the above scheme, anti-collision strips are arranged on the opposite sides of the left and right protective cover doors, and the anti-collision strips are made of rubber.
[0009] As a preferred scheme of the above scheme, the left protective cover door and the right protective cover door are both provided with a visual window.
[0010] Compared with the prior art, the left protective cover door and the right protective cover door are in rolling cooperation with the guide rails through the first roller and the second roller, so that the noise generated by friction can be reduced; meanwhile, the limiting groove is arranged below the left protective cover door and the right protective cover door, the limiting spring and the limiting block are arranged in the limiting groove, and when the protective cover door is closed, the limiting spring and the limiting block can form a limiting structure with the limiting rod on the guide rail, so that the problem that the protective cover door is not tightly closed due to inertia can be avoided.

[0013] Figure 3 It is a schematic view of the protective cover door in a closed state;
[0014] Figure 4 It is a partial enlarged view of Figure 3
[0015] Figure 5 It is a schematic view of cooperation between the protective cover door and the guide rail.
[0016] In the drawing, marks are as follows: protective cover main body 1, left protective cover door 2, right protective cover door 3, visual window 4, upper guide rail 5, lower guide rail 6, first roller 71, second roller 72, limiting groove 8, limiting spring 9, limiting block 10, limiting rod 11, plug block 12. DETAILED DESCRIPTION
[0017] In the description of the utility model, it needs to be explained that for the orientation words, if the terms "center", "transverse (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate the orientation and positional relationship based on the orientation or positional relationship shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and not indicating or implying that the indicated device or element must have a particular orientation, a particular orientation and operation, and cannot be understood as limiting the specific protection scope of the utility model.
[0018] In addition, the terms "first", "second", or the like used in the description of the present application are only for descriptive purposes and cannot be construed as indicating or implying relative importance or implying the number of technical features. Therefore, the definition of "first", "second" features can explicitly or implicitly include one or more features, and in the description of the present application, the meaning of "several" or "several" is two or more, unless otherwise explicitly specified.
[0019] Referring to the drawings. The noise reduction shield described in the embodiment includes a shield body 1, the shield body 1 is assembled by sheet metal panel, the front side of the shield body 1 is provided with movable left shield door 2 and right shield door 3, the opposite side edges of the left shield door 2 and the right shield door 3 are provided with anti-collision strips, and the anti-collision strips are made of rubber material. The left shield door 2 and the right shield door 3 are both provided with a viewing window 4.
[0020] The front side of the shield body 1 is respectively provided with an upper guide rail 5 and a lower guide rail 6, and the upper guide rail 5 and the lower guide rail 6 are provided with sliding grooves; the upper and lower sides of the left shield door 2 and the right shield door 3 are respectively provided with a plurality of vertically arranged first rollers 71 and horizontally arranged second rollers 72, which are in rolling cooperation with the groove bottom and the two side groove walls of the sliding groove, so as to reduce the noise caused by sliding friction.
