Description

Technical Field

[0001] The utility model relates to the field of machine tools, in particular to a column and a machine tool. Background Art

[0002] As one of the important parts of boring machines, the column is mainly used to connect the machine bed and support the spindle box to move vertically. Therefore, the machine column needs to have sufficient rigidity. At present, the structure adopted by most boring machine columns is a double-layer cavity structure (such as Figure 1 As shown), this structure can install a heavy hammer in the cavity to balance the weight of the spindle box. For example, the announcement number CN214816504U discloses a machine tool column, which specifically discloses that the main body is provided with a first cavity and a second cavity, the first cavity and the second cavity are separated by a plate, the second cavity is located above the first cavity, and the two guide rails are located directly above the second cavity. The two guide rails are symmetrically arranged relative to the second cavity. Although the double-layer cavity structure improves the rigidity of the local area of ​​the guide rail when the column is subjected to concentrated loads and ensures the smaller deformation of the column as a whole, when there is no need to install a heavy hammer inside the column cavity, the double-layer column structure design leads to a waste of production costs. At the same time, the casting of this structure takes longer to cool, and is more likely to produce defects such as shrinkage cavities and bubbles, which affects the service life of the column.

[0003] Therefore, a column and a machine tool are now proposed to solve the above problems. Utility Model Content

[0012] In a preferred embodiment of the utility model, a weight-reducing hole is provided on the side wall reinforcement rib, and the weight-reducing hole is provided in the middle part of the side wall reinforcement rib.

[0013] In a preferred embodiment of the utility model, the supporting side wall is further provided with a heat dissipation hole, and the heat dissipation hole penetrates the supporting side wall and communicates with the outside.

[0028] 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.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] like Figure 1 As shown, the structure adopted by most boring machine columns in the prior art is a double-layer cavity 10 structure, in which a heavy hammer can be installed in the cavity 10 to balance the weight of the spindle box 3. Although the double-layer cavity 10 structure improves the rigidity of the local area of ​​the guide rail 2 when the column is subjected to concentrated loads and ensures a smaller deformation of the entire column, when there is no need to install a heavy hammer inside the column cavity 10, the double-layer column structure design leads to a waste of production costs. At the same time, the casting of this structure takes longer time to cool, and is more likely to produce defects such as shrinkage cavities and bubbles, which affects the service life of the column. Therefore, a column and a machine tool are now proposed to solve the above problems.

[0032] like Figures 2 to 5 As shown, a column structure includes: a column 1 and a guide rail 2, wherein the guide rail 2 is installed on one side of the column 1, and a cavity 10 is arranged in the column 1. Compared with the structure of two cavities 10 in the prior art, the production cost and the cooling time of casting are saved, and the manufacturing process is simplified, thereby reducing the defects such as shrinkage holes and bubbles generated during the manufacturing process.

[0033] A supporting side wall 11 and a supporting reinforcement rib 12 are arranged in the cavity 10. The supporting side wall 11 includes a guide rail 2 supporting side wall 110 and a column supporting side wall 111. Preferably, the guide rail 2 supporting side wall 110 is arranged on a side close to the guide rail 2, and the column supporting side wall 111 is arranged on the opposite side of the guide rail 2 supporting side wall 110.

[0034] One end of the support reinforcement rib 12 is connected to the guide rail 2 support side wall 110, and the other end is connected to the column support side wall 111. Preferably, both the guide rail 2 support side wall 110 and the column support side wall 111 are provided with mounting holes 114, and the support reinforcement rib 12 is inserted into the mounting hole 114. The setting of the mounting hole 114 can more conveniently complete the installation of the support reinforcement rib 12.

[0035] By setting the column supporting side wall 111 on the opposite side of the guide rail 2 supporting side wall 110, the integrity of the wall structure of the cavity 10 can be better achieved. When the column is subjected to force, the load is evenly transmitted to the supporting parts of the entire column through the supporting reinforcement ribs 12, which fully enhances the structural rigidity of the column such as bending resistance, torsion resistance, and compression resistance, while also avoiding the problem of insufficient structural rigidity of the single cavity 10.

[0036] The supporting side wall 11 is also provided with a side wall reinforcement rib 113, which is used to strengthen the bending and torsion resistance of the side wall of the cavity 10. The supporting reinforcement rib 12 is inserted into the side wall reinforcement rib 113. By connecting the supporting reinforcement rib 12 to the side wall reinforcement rib 113, the first force-bearing body when the column is subjected to force is the reinforcement rib, thereby enhancing the overall compressive resistance of the column.

[0037] In a preferred embodiment of the utility model, there are a plurality of support reinforcement ribs 12, and the plurality of support reinforcement ribs 12 are arranged at equal intervals between the guide rail 2 support side wall 110 and the column support side wall 111. The plurality of reinforcement ribs can better enhance the overall rigidity of the column, and the equidistant arrangement makes the load force decomposition more even.

[0038] In a preferred embodiment of the utility model, the mounting hole 114 of the guide rail 2 supporting the side wall 110 is set in the middle of the guide rail 2, and the support reinforcement rib 12 is set in the middle of the guide rail 2 to ensure that the support force of the support reinforcement rib 12 on the guide rail 2 is the same during the movement of the guide rail 2 of the spindle box 3, thereby improving the compressive strength. The edge of the mounting hole 114 is connected to the side wall reinforcement rib 113 as a whole, so that the load force on the support reinforcement rib 12 can be better transmitted to the side wall reinforcement rib 113.

[0039] In a preferred embodiment of the utility model, the side wall reinforcement rib 113 is a cross-shaped or well-shaped structure, which is more conducive to the decomposition of load force. The side wall reinforcement rib 113 is provided with a weight reduction hole 1130, and the weight reduction hole 1130 is arranged in the middle of the side wall reinforcement rib 113 to reduce the overall weight of the column 1.

[0040] In a preferred embodiment of the utility model, heat dissipation holes 13 are further provided on the supporting side wall 11. The heat dissipation holes 13 penetrate the supporting side wall 11 and communicate with the outside. There are a plurality of heat dissipation holes 13, and the plurality of heat dissipation holes 13 are distributed in rows. Each guide rail 2 supporting side wall 110 and column supporting side wall 111 are provided with at least two rows of heat dissipation holes 13. The arrangement of the heat dissipation holes 13 can effectively accelerate the heat dissipation speed of the column 1, thereby avoiding the column 1 from generating a large casting stress during use, and reducing the possibility of deformation and cracking of the column 1.

[0041] The utility model also provides a machine tool, which includes the above-mentioned column. When the spindle box 3 is working on the guide rail 2, the spindle box 3 applies force to the guide rail 2, and the guide rail 2 is subjected to a load force. The load force is transmitted to the support wall of the guide rail 2, and it is connected by the support reinforcement rib 12 and the column support wall to achieve the integrity of the wall structure of the cavity 10, and the load force is evenly transmitted to each supporting part of the entire column, which fully enhances the structural rigidity of the column such as bending resistance, torsion resistance and compression resistance. Secondly, only one cavity 10 is arranged in the column body 1. Compared with the structure of two cavities 10 in the prior art, it saves production costs and casting cooling time, and simplifies the manufacturing process, thereby reducing defects such as shrinkage bubbles generated during the manufacturing process. In addition, the column designed with the above-mentioned column structure can also solve the problem of insufficient rigidity of the single cavity 10 structure of the column of the utility model.

[0042] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications and improvements can be made, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the utility model, and all of them belong to the protection scope of the utility model.
