SUMMARY

[0004] The utility model aims at providing an organ cover of a crown gantry machine tool to solve the above technical problems.

[0005] To achieve the above purpose, the technical scheme of the utility model is as follows: an organ cover of a crown gantry machine tool, the organ cover is a folding organ cover, comprising an outer cover, an inner cover, and a plurality of support skeletons connected between the outer cover and the inner cover in parallel and vertically, the outer cover is located above the outer periphery of the inner cover, the outer cover comprises an inclined outer top cover surface and an outer vertical cover surface extending downward at the left and right ends of the outer top cover surface, the inner cover comprises a herringbone-shaped inner top cover surface and an inner vertical cover surface extending downward at the left and right ends of the inner main body cover surface, the shape enclosed between the outer cover and the inner cover corresponds to the shape of the support skeleton.

[0006] Preferably, the included angle between the outer top cover surface and the horizontal plane ranges from 15 to 45 degrees.

[0007] Preferably, the included angle of the inner top angle of the inner top cover surface ranges from 90 to 120 degrees.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] See Figures 1-4As shown, as an embodiment of this utility model, a bellows cover for a crane gantry machine tool is provided, specifically a bellows cover for a large crane gantry machine tool with a large oblique angle and wide span. The bellows cover is a folding bellows cover, including an outer cover 3, an inner cover 4, and multiple supporting frames 5 arranged side by side and vertically connected between the outer cover 3 and the inner cover 4. The outer cover 3 and the inner cover 4 are folded to form multiple folds. The outer cover 3 is located above the outer periphery of the inner cover 4. The outer cover 3 includes an inclined outer top cover surface 31 and outer vertical cover surfaces 32 located at the left and right ends of the outer top cover surface 31 and extending downward. The inner cover 4 includes a herringbone-shaped inner top cover surface 41 and inner vertical cover surfaces 42 located at the left and right ends of the inner main cover surface and extending downward. The shape formed by the outer cover 3 and the inner cover 4 corresponds to the shape of the supporting frame 5. This structural design allows the outer top surface 31 of the bellows cover to be set more inclined and higher, ensuring that chips can naturally and smoothly roll off its surface to the inside of the machine tool 1, avoiding chip accumulation. At the same time, the structural design of the inner cover 4 and the support frame 5, with the bottom of the inner cover 4 and the support frame 5 being symmetrical, greatly strengthens the overall structure of the bellows cover, making the support frame 5 more supportive and able to maintain a vertical state at all times. This ensures the stability of the bellows cover's expansion and contraction, while eliminating the need to thicken the support frame 5, thus not reducing the moving speed of the bellows cover, shortening the length of the bellows cover after compression, and improving the expansion and contraction effect.

[0026] In this embodiment, the angle between the outer top cover 31 and the horizontal plane is in the range of 15 to 45°, specifically 30°, so that the chips can roll off the surface of the machine tool 1 more quickly and naturally, and further effectively avoid the situation of chip retention.

[0027] In this embodiment, the angle range of the inner top angle of the inner top cover 41 is 90 to 120°, specifically 120°, thereby ensuring the support stability of the support frame 5.

[0028] In this embodiment, the distance between the two inner upright covers 42 of the inner cover 4 is less than the distance between the two outer upright covers 32 of the outer cover 3. The bottom ends of the outer upright covers 32 and the inner upright covers 42 are flush, thereby balancing the left and right ends of the bellows cover and ensuring its telescopic stability.

[0029] In this embodiment, the support frame 5 is a vertical plate. An armor plate 6 is provided on one side of the top of the vertical plate. The vertical plate is connected between the outer cover 3 and the inner cover 4. The armor plate 6 protrudes from the outside of the outer cover surface 32. The armor plate 6 can provide protection for the accordion cover, thereby preventing chips from falling and getting stuck at the folds of the accordion cover.

[0030] In this embodiment, the armor plate 6 includes a front inclined plate 61 disposed on one side of the top of the vertical plate and a rear inclined plate 62 located on the side of the front inclined plate 61 away from the vertical plate. The slope of the front inclined plate 61 is greater than that of the rear inclined plate 62, so that when the accordion cover is folded and retracted, the rear inclined plate 62 of the armor plate 6 rests on the top of the front inclined plate 61 of the adjacent armor plate 6 behind it, which can reduce the length of the accordion cover when folded and retracted and save space.

[0031] In this embodiment, the folds of the outer cover 3 and the inner cover 4 have the same width and the same number of folds, ensuring that the outer cover 3 and the inner cover 4 of the accordion cover can move synchronously and ensure operational stability. Furthermore, the number of support frames 5 is less than the number of folds in the outer cover 3 and the inner cover 4, and the support frames 5 are evenly spaced between the outer cover 3 and the inner cover 4. Specifically, two adjacent support frames 5 are spaced 5 folds apart, further reducing the length of the accordion cover after folding. Of course, two adjacent support frames 5 can also be spaced 3 folds apart; this is not a limitation.

[0032] In this embodiment, the outer cover 3 and the inner cover 4 are foldable flexible fabric covers, and the support frame 5 is a metal support frame 5, thereby ensuring the protective effect.

[0033] See Figure 5 and 6 As shown in the figure, as an embodiment of the present invention, the present invention also provides a crane gantry machine tool, including a machine tool 1 and a bellows cover of the crane gantry machine tool described in the above embodiment. Columns 2 are respectively provided on the left and right sides of the machine tool 1. There are two bellows covers, which are installed opposite each other on the top surfaces of the columns 2 on the left and right sides of the machine tool 1. The outer top surface 31 of the bellows cover is gradually inclined downwards towards the machine tool 1. This structural design allows the outer top surface 31 of the bellows cover to be set more inclined and higher, ensuring that chips can naturally and smoothly roll off the surface of the outer top surface 31 to the inside of the machine tool 1, avoiding chip accumulation. At the same time, the structural design of the inner cover 4 and the supporting frame 5 greatly strengthens the overall structure of the bellows cover, making the supporting frame 5 more supportive and always maintaining a vertical state, thus ensuring the stability of the bellows cover's expansion and contraction. Furthermore, there is no need to thicken the supporting frame 5, thus not reducing the moving speed of the bellows cover, shortening the compressed length of the bellows cover, and improving the expansion and contraction effect.

[0034] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that any changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
