DETAILED DESCRIPTION

[0035] The present application will be further described in detail below in combination with the drawings and embodiments.

[0036] An embodiment of the present application discloses a three-dimensional five-axis laser cutting machine ram structure.

[0037] Referring to Figure 1 , a three-dimensional five-axis laser cutting machine ram structure includes a ram body 1 and a sliding assembly 2. Among them, the ram body 1 is used for installing the laser equipment to drive the laser equipment to displace in space, and the sliding assembly 2 is used to drive the ram body 1 to move.

[0038] The ram body 1 is made of cast aluminum material, which is light in weight. The ram body 1 is in a long strip shape, and its cross section is polygonal. And the ram body 1 is a hollow structure, having a hollow chamber 11 for reducing the overall weight.

[0039] Further, the number of sides of the cross section of the ram body 1 is not less than five. Compared with the conventional ram body 1 with a cross section of quadrilateral, the more the number of sides of the polygon, the smaller the cross section circumference of the ram body 1, and the lighter the weight of the ram body 1. In the embodiment, the number of sides of the cross section of the ram body 1 is six, so that the ram body 1 is convenient to process, and the ram body 1 still has a relatively wide space for the installation of the sliding assembly 2.

[0040] Referring to Figure 2 , further, in order to improve the overall structural strength of the ram body 1, the ram body 1 is provided with a reinforcing rib structure 3 in the hollow chamber 11. The reinforcing rib structure 3 includes longitudinal ribs 31 and transverse ribs 32.

[0041] The longitudinal ribs 31 are arranged along the length direction of the ram body 1, and can improve the bending deformation resistance of the ram body 1.

[0042] The cross section shape of the transverse ribs 32 is consistent with the cross section shape of the hollow chamber 11, and the transverse ribs 32 are arranged along the length direction of the ram body 1. The transverse ribs 32 can support the inner wall of the hollow chamber 11, thereby improving the extrusion resistance of the ram body 1.

[0043] Further, the transverse ribs 32 are provided with through holes 33 along the length direction of the ram body 1, and the cross section of the through holes 33 is circular. By arranging the circular through holes 33, an arc-shaped support is formed, further improving the extrusion resistance of the ram body 1.

[0044] Referring to Figure 1 , the sliding assembly 2 includes a wire rail 21, a sliding block 22 slidingly mounted on the wire rail 21, and a rack 23. The sliding block 22 and the rack 23 are connected with an external saddle. The rack 23 is connected with an external saddle gear, and the rack 23 and the ram body 1 are driven to move up and down by the external saddle. The sliding block 22 is fixedly connected with the external saddle, and when the ram body 1 moves up and down, the wire rail 21 slides relative to the sliding block 22.

[0045] Referring to Figure 1 and Figure 2 , further, the ram body 1 has a wire rail mounting surface 12, a rack mounting surface 13, and a laser mounting surface 14. The wire rail mounting surface 12 is used for mounting the wire rail 21, the rack mounting surface 13 is used for mounting the rack 23, and the laser mounting surface 14 is used for mounting a laser. Further, the wire rail mounting surface 12 and the rack mounting surface 13 are not in the same plane, so that the wire rail 21 and the rack 23 are located in two directions of the ram body 1. When the ram body 1 is mounted on the external saddle, the ram body 1 has a large maintenance gap with the external saddle, and maintenance is convenient.

[0046] Further, the number of the linear rails 21 is two, which are arranged on both sides of the linear rail mounting surface 12, and a plurality of sliding blocks 22 slide on each linear rail 21. The slide block body 1 slides on the external saddle through the two linear rails 21 simultaneously, so that the slide block body 1 runs more stably.

[0047] With reference to Figure 1 , the slide block body 1 is provided with an anti-collision rubber block 4 at the upper and lower ends of the linear rail mounting surface 12, and the anti-collision rubber block 4 has elasticity. When the slide block body 1 moves to the highest or lowest position, the anti-collision rubber block 4 can be abutted, so as to reduce the impact force when the slide block body 1 stops.

[0048] With reference to Figure 1 and Figure 3 , further, the bottom of the linear rail 21 and the lower end of the linear rail mounting surface 12 are provided with an oil receiving box 6. When the sliding block 22 slides on the linear rail 21, the lubricating oil dripping due to gravity can fall into the oil receiving box 6, so that the lubricating oil is not easy to pollute the laser.

[0049] With reference to Figure 1 , further, in order to avoid dust adhering to the rack 23 and affecting the transmission accuracy, the slide block body 1 is provided with an organ cover assembly 5 on the rack mounting surface 13, and the organ cover assembly 5 can cover the rack 23. The organ cover assembly 5 includes an organ cover fixing plate 51 and an organ cover 52. The number of the organ cover fixing plate 51 is two, which are fixedly arranged at the upper and lower ends of the rack mounting surface 13 and located at the two ends of the rack 23. The number of the organ cover 52 is also two, and one end of each organ cover 52 is fixedly connected with the organ cover fixing plate 51, and the other end is connected with the external saddle simultaneously.

[0050] When the external saddle drives the slide block body 1 to move through the rack 23, the organ cover 52 can be extended and shortened with the external saddle, one of which is extended and the other of which is shortened, so that the organ cover 52 can always cover the rack 23.

[0051] With reference to Figure 1 and Figure 4 , the slide block body 1 is further provided with a supporting slide 53 on both sides of the rack mounting surface 13, and the organ cover 52 is provided with a limiting groove 54. The organ cover 52 is slidably connected with the supporting slide 53 through the limiting groove 54, so that the organ cover 52 can slide on the supporting slide 53 when it is extended and retracted, so as to guide the extension and retraction of the organ cover 52 and avoid the derailment of the organ cover 52.

[0052] The embodiment of the three-dimensional five-axis laser cutting machine slide structure of the utility model is implemented by the following principle: the slide body 1 is set as a hollow structure, and the cross section of the slide body 1 is a polygon, so that the weight of the slide body 1 is lighter than the existing one; and longitudinal ribs 31 and cross ribs 32 are arranged in the hollow chamber 11 of the slide body 1, so as to improve the structural strength of the slide body 1, so that the slide body 1 is not easy to deform under stress in the use process, thereby realizing the light weight of the slide body 1.

[0053] The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited to the above-mentioned embodiment only, and any technical scheme belonging to the idea of the utility model belongs to the protection scope of the utility model. It should be pointed out that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the utility model can also be regarded as the protection scope of the utility model.
