[0002] The gantry is an important part of a double-rail machine tool and is used to support and guide the movement of tools. The gantry is composed of two columns and a cross beam. As one of the key parts of the gantry machine tool, the column is the main load-bearing part of the gantry. During its operation and use, it is not only subjected to the positive pressure from components such as the cross beam and the saddle, but also subjected to bending and torsional moments. In traditional designs, in order to ensure the structural rigidity and strength of the column, the four walls of the column are usually thickened. As a result, the overall weight of the column increases too much. To address this problem, in the prior art, a method of adding reinforcing rib plates inside the column is adopted to improve the rigidity and strength of the column, but the overall weight of the column is still relatively large, which does not meet the requirements of the existing lightweight design, and the vibration on the cross beam will be transmitted to the column, reducing the reliability of the connection between the column and the cross beam; Based on this, this application proposes a lightweight structure of a gantry column of a double-rail machine tool.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] The present utility model provides a lightweight structure for the gantry column of a double-track machine tool, including a column body 1. The column body 1 is a hollow structure, and hollow holes 2 are evenly arranged on the side wall of the column body 1. A reinforcing pipe 6 is fixedly connected to the inner side of the hollow hole 2. The inner diameter of the reinforcing pipe 6 is the same as that of the hollow hole 2, and the hollow holes 2 at the same height on both sides of the column body 1 are connected by the reinforcing pipe 6. Through the arrangement of the reinforcing pipe 6, the strength of the opening part of the column body 1 can be improved. Through the arrangement of the column body 1, the weight of the column body 1 can be reduced.
[0021] A number of reinforcing rib plates 5 are fixedly connected to the inner wall of the column body 1. The thickness of the reinforcing rib plates 5 is uniform, and the reinforcing rib plates 5 are evenly distributed in the inner cavity of the column body 1. The distribution of the reinforcing rib plates 5 enables them to be evenly stressed inside the column, improving the safety performance of the gantry column. Moreover, multiple triangular structures are formed between the reinforcing rib plates 5 and the column body 1 and between the reinforcing rib plates 5, improving the stability and strengthening effect of the reinforcing rib plates 5 and enhancing the structural strength of the column body 1, making it not easy to break.
[0022] A reinforcing rib plate 5 is fixed at the end of the reinforcing pipe 6. Fillets are provided at the connection part between the reinforcing rib plate 5 and the reinforcing pipe 6, and fillets are also provided at the connection part between the reinforcing rib plate 5 and the column body 1. Through the design of the fillets, the stress at this part of the gantry column can be reduced, thereby enhancing the structural strength of the gantry column.
[0023] An inclined support plate 3 is fixedly connected to the inner side of the top of the column body 1. Vertical rib plates 4 are evenly fixedly connected to the top of the inclined support plate 3. The vertical rib plates 4 are provided with hollow holes to reduce the weight of the vertical rib plates 4. The vertical rib plates 4 are triangular structures, and fillets are provided at the ends of the vertical rib plates 4. Through the arrangement of the vertical rib plates 4, the reliability of the connection between the inclined support plate 3 and the column body 1 and the connection between the gantry column and the gantry crossbeam can be improved.
[0024] Weight reduction holes 7 are formed on the inclined support plate 3. The weight reduction holes 7 and the vertical rib plates 4 are arranged alternately. A buffer plate 9 is fixedly connected to the top of the inclined support plate 3. The material of the buffer plate 9 can be rubber. The vertical rib plates 4 are located between two adjacent buffer plates 9, and the vertical rib plates 4 are in contact with the buffer plates 9. Through the arrangement of the buffer plates 9, the resilience of the buffer plates 9 can reduce the force transmitted from the crossbeam to the gantry column through the vertical rib plates, improving the reliability of the connection between the gantry column and the gantry crossbeam.
[0025] The tops of the column body 1, the vertical rib plates 4, and the diagonal brace plates 3 are at the same height, facilitating the connection between the gantry column and the gantry crossbeam. A number of grooves 8 are provided at the bottom end of the column body 1. Bolt holes 10 or positioning holes 11 are provided at the bottom of the grooves 8. A positioning rod is provided in the positioning hole 11. When the gantry column is in use, the positioning rod is fixed to the double-track machine tool base. The positioning rod can limit the position between the column body 1 and the machine tool base, reducing the influence of vibration on the fixing bolts and further improving the stability of the gantry column.
[0026] In summary: When the lightweight structure of the gantry column of the double-track machine tool is in use, the top of the gantry column is connected to the gantry crossbeam, as Figure 4 shown, and Figure 4 the model of the double-track machine tool in
[0027] is BSM-3221. The column body 1 and the diagonal brace plate 3 support the gantry crossbeam at the same time, increasing the contact area between the gantry column and the gantry crossbeam, reducing the probability of deformation of the gantry crossbeam, and increasing the reliability of the connection between the column and the crossbeam. The gantry column is a hollow structure. The hollow holes 2, grooves 8, and weight-reducing holes 7 provided thereon all reduce the weight of the gantry column and the influence of the gantry column on the machine tool base. The setting of the reinforcing rib plates 5 and reinforcing tubes 6 improves the structural strength of the column body 1, enabling the gantry column to meet the requirements of lightweight design while ensuring structural strength. The standard parts used in the present invention can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art, which will not be elaborated here. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
