Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0038] See also Figure 1 to Figure 2 An embodiment of the present application provides a machine tool 100 , which includes a base 110 , a machining assembly 120 , and a column structure 130 .

[0039] The machine tool 100 may be a CNC machine tool or other machine tools. For example, the machine tool 100 may be a five-axis machining machine tool.

[0040] The column structure 130 is installed on the base 110 , and the machining assembly 120 can be movably installed on the column structure 130 . The base 110 can be used to support the column structure 130 , and the column structure 130 can be used to install and support the machining assembly 120 and other structural parts.

[0041] The machining assembly 120 can be used to process parts. For example, the machining assembly 120 can include a saddle 121 and a spindle box 122. The saddle 121 is movably mounted on the column structure 130 along a first direction X, and the spindle box 122 is movably mounted on the saddle 121 along a second direction Y. A tool can be installed in the spindle box 122. The movement of the saddle 121 along the first direction X can drive the tool to move along the first direction X. When the spindle box 122 moves along the second direction Y, it can drive the tool to move along the second direction Y. Thus, the tool can move in multiple directions to facilitate machining of parts.

[0042] The second direction Y may be a vertical direction, the first direction X may be a horizontal direction, and the first direction X may be perpendicular to the second direction Y.

[0043] In some embodiments, the machine tool 100 may further include a tool change magazine 150 . The tool change magazine 150 may be installed on the column structure 130 and located in the moving path of the machining assembly 120 , so as to facilitate replacement of the tool on the machining assembly 120 .

[0044] In some embodiments, the machine tool 100 may further include a machine table 140 , which is movably mounted on the base 110 . The machine table 140 may be used to fix parts so that the machining assembly 120 can machine the parts.

[0045] For example, the machine tool worktable 140 may be movably disposed on the base 110 along a third direction Z, the third direction Z may be a horizontal direction, and the third direction Z may be perpendicular to the first direction X.

[0046] In some embodiments, the column structure 130 includes a mounting portion 131 , a first supporting portion 133 , a second supporting portion 134 , and a third supporting portion 135 , and the first supporting portion 133 , the second supporting portion 134 , and the third supporting portion 135 are all connected to the mounting portion 131 .

[0047] The mounting portion 131 is used to mount the machining assembly 120 . For example, the machining assembly 120 is movably mounted on the mounting portion 131 . Specifically, the saddle 121 is movably mounted on the base 110 .

[0048] The ends of the first support portion 133, the second support portion 134 and the third support portion 135 facing away from the mounting portion 131 are all used for mounting on the base 110, and the planes where the first support portion 133 and the second support portion 134 are located are set at an angle to the planes where the third support portion 135 and the second support portion 134 are located, or the arrangement direction of the first support portion 133 and the second support portion 134 is set at an angle to the arrangement direction of the third support portion 135 and the second support portion 134, or the third support portion 135 is located on one side of the first support portion 133 in the direction of the second support portion 134. In this way, compared with the column structure using a double support structure in the related art, the column structure 130 provided in the embodiment of the present application uses three support portions (the first support portion 133, the second support portion 134 and the third support portion 135), which helps to improve the rigidity of the column structure 130 and improve the stress deformation of the column structure 130. Furthermore, since the column structure 130 can be installed on the base 110 through three support parts, the three support parts are arranged in a non-linear manner, and the three support parts are distributed roughly in a triangle to support the machining component 120 from multiple directions. This helps to improve the situation in which the column structure 130 shakes due to the inertia generated when the machining component 120 moves, thereby causing the machining component 120 to tip over, thereby improving the stability and rigidity of the column structure 130 and improving the machining accuracy of the machine tool 100.

[0049] The plane where the first support portion 133 and the second support portion 134 are located may be a vertical plane perpendicular to the horizontal plane, and the plane where the second support portion 134 is located may also be a vertical plane perpendicular to the horizontal plane.

[0050] The first support portion 133 , the second support portion 134 and the third support portion 135 may be mounted on the base 110 by means of fixing members, and the fixing members may be bolts, screws, rivets or other fixing structures.

[0051] The plane where the first support portion 133 and the second support portion 134 are located is arranged at an angle with the plane where the third support portion 135 and the second support portion 134 are located, wherein the angle may be an acute angle, an obtuse angle or a right angle. For example, the angle may be greater than or equal to 70 degrees and less than or equal to 110 degrees, which helps the column structure 130 to be more stable.

[0052] The arrangement direction of the first support portion 133 and the second support portion 134 is arranged at an angle with the arrangement direction of the third support portion 135 and the second support portion 134, wherein the angle may be an acute angle, an obtuse angle or a right angle. For example, the angle may be greater than or equal to 70 degrees and less than or equal to 110 degrees, which helps to make the column structure 130 more stable.

[0053] As an example, when the included angle is an acute angle, it helps to reduce the overall size of the column structure 130 , thereby reducing the overall size of the machine tool 100 .

[0054] As another example, when the included angle is an obtuse angle, it helps to provide a larger movement space for the machining assembly 120 .

[0055] As another example, when the included angle is a right angle, it helps the third support portion 135 to more stably support the machining assembly 120 , further improving the situation where the machining assembly 120 topples over.

[0056] The third support portion 135 is located on one side of the first support portion 133 in the direction toward the second support portion 134 , which may refer to the left and right sides along the direction from the first support portion 133 to the second support portion 134 . The third support portion 135 may be located on the left or right side of the direction from the first support portion 133 to the second support portion 134 .

[0057] In some embodiments, the column structure 130 can be an integrally formed structure. This can further improve the rigidity of the column structure 130, help the column structure 130 to more stably support the machining assembly 120, and further improve the stress shaking and deformation of the column structure 130. In addition, the column structure 130 adopts an integrally formed structure, so there is no need to connect and install the various structural parts of the column structure 130, which helps to avoid the impact of installation errors on the processing accuracy of the machine tool 100, and also helps to avoid the loose connection between the various structural parts of the column structure 130 due to long-term use, further improving the stability of the column structure 130 and helping to ensure the processing accuracy of the machine tool 100.

[0058] As an example, the column structure 130 may be cast as an integrally formed structure, or the column structure 130 may be formed as an integrally formed structure by other methods.

[0059] Specifically, the mounting portion 131, the first support portion 133, the second support portion 134 and the third support portion 135 may be an integrally formed structure. In some other embodiments, the mounting portion 131, the first support portion 133, the second support portion 134 and the third support portion 135 may also be connected by a fixing member, wherein the fixing member may be a bolt, a screw, a rivet or other fixed structure.

[0060] In some embodiments, the column structure 130 may further include a connecting portion 136, which may be connected to the third support portion 135 and the second support portion 134, helping to further improve the rigidity and stability of the column structure 130, and when the machining assembly 120 moves, the connecting portion 136 may play a role in transmitting force between the third support portion 135 and the second support portion 134, helping to further improve the shaking and deformation of the column structure 130 under force.

[0061] In some embodiments, the connecting portion 136 , the mounting portion 131 , the first supporting portion 133 , the second supporting portion 134 and the third supporting portion 135 are an integrally formed structure, so that the rigidity and stability of the column structure 130 can be further improved.

[0062] As an example, the connecting portion 136, the mounting portion 131, the first supporting portion 133, the second supporting portion 134 and the third supporting portion 135 can be cast into an integrally formed structure. In some other embodiments, the connecting portion 136 can also be connected to the second supporting portion 134 and the third supporting portion 135 by a fixing member, wherein the fixing member can be a bolt, a screw, a rivet or other fixed structure.

[0063] In some embodiments, the connecting portion 136 can be connected to the end of the second supporting portion 134 and the third supporting portion 135 that is away from the mounting portion 131. In this way, a larger space can be reserved between the connecting portion 136 and the mounting portion 131 for installing other structural components. For example, the space between the connecting portion 136 and the mounting portion 131 can be used to install the tool changing magazine 150.

[0064] The connection part 136 is connected to the end of the second support part 134 and the third support part 135 away from the mounting part 131, which may mean that the connection part 136 is located at the end surface of the second support part 134 and the third support part 135 away from the mounting part 131, and the second support part 134 and the third support part 135 can be mounted on the base 110 through the connection part 136. Alternatively, the connection part 136 is connected to the end of the second support part 134 and the third support part 135 away from the mounting part 131, which may mean that the connection part 136 is connected to the end of the second support part 134 and the third support part 135 away from the mounting part 131 and is located between the second support part 134 and the third support part 135, and the second support part 134 and the third support part 135 can be mounted on the base 110, and the connection part 136 can be mounted on the base 110 or not.

[0065] In some embodiments, the mounting portion 131 may include a first mounting portion 1310 and a second mounting portion 1320 connected to each other, and the first mounting portion 1310 and the second mounting portion 1320 are arranged at an angle, so that a space may be reserved between the first mounting portion 1310 and the second mounting portion 1320 for installing other structural members. For example, the first mounting portion 1310 and the second mounting portion 1320 may be substantially vertical. For example, the angle between the first mounting portion 1310 and the second mounting portion 1320 may be greater than or equal to 70 degrees and less than or equal to 110 degrees, which helps to make the column structure 130 more stable.

[0066] The first support portion 133 and the second support portion 134 are connected to the first mounting portion 1310, and the first mounting portion 1310 is used to mount the machining assembly 120. The third support portion 135 is connected to the second mounting portion 1320. The third support portion 135 and the machining assembly 120 are located on the side of the first support portion 133 facing the second support portion 134. In this way, the first support portion 133 and the second support portion 134 can stably support the machining assembly 120 along the direction of the base 110 toward the column, and the third support portion 135 can support the machining assembly 120 from the first support portion 133 toward the side of the second support portion 134, which helps to prevent the machining assembly 120 from tipping over, and helps to prevent the first support portion 133, the second support portion 134 and the first mounting portion 1310 from tipping over.

[0067] Specifically, the third supporting portion 135 and the machining assembly 120 may be located on the same side of the first mounting portion 1310 .

[0068] In some embodiments, the first mounting portion 1310 is provided with a first slide rail 1311 and a second slide rail 1312, and the first slide rail 1311 and the second slide rail 1312 are used to slideably connect the machining assembly 120, so that the machining assembly 120 can slide back and forth on the first slide rail 1311 and the second slide rail 1312 to drive the tool to move, thereby processing the parts.

[0069] The first slide rail 1311 and the second slide rail 1312 are distributed in a stepped manner along the height direction of the column structure 130 , so that the machining assembly 120 can slide more stably.

[0070] The first slide rail 1311 and the second slide rail 1312 are distributed in a stepped manner along the height direction of the column structure 130 , which specifically means that the first slide rail 1311 and the second slide rail 1312 have a distance difference along the second direction Y, and may also have a distance difference along the third direction Z.

[0071] In some embodiments, the first slide rail 1311 and the second slide rail 1312 may be staggered from each other in the height direction to support the machining assembly 120 at different height positions, which helps to support the machining assembly 120 more stably.

[0072] The first slide rail 1311 may include a first mounting surface connected to the first mounting portion 1310, and the first slide rail 1311 may also include a first slide rail surface 1313 arranged opposite to the first mounting surface; similarly, the second slide rail 1312 may include a second mounting surface connected to the first mounting portion 1310, and the second slide rail 1312 may also include a second slide rail surface 1314 arranged opposite to the second mounting surface.

[0073] Both the first slide rail surface 1313 and the second slide rail surface 1314 can be used for sliding connection of the machining assembly 120 .

[0074] The first slide rail surface 1313 and the second slide rail surface 1314 are both arranged upward. Compared with the technical solution of setting the slide rail surface on the side in the related art, the first slide rail surface 1313 and the second slide rail surface 1314 in the embodiment of the present application are both arranged upward, which helps the first slide rail 1311 and the second slide rail 1312 to more stably support the machining component 120.

[0075] The first slide rail surface 1313 and the second slide rail surface 1314 are both arranged to face upward, which may mean that the first slide rail surface 1313 and the second slide rail surface 1314 are both facing the side of the column structure 130 away from the base 110 .

[0076] In some embodiments, the column structure 130 may be provided with a processing space 137, wherein the first support portion 133 and the second support portion 134 may define a first vertical plane, the third support portion 135 and the second support portion 134 may define a second vertical plane, and the processing space 137 is defined between the first vertical plane and the second vertical plane, and the processing space 137 is used for the movement of the machining assembly 120. In this way, the center of gravity of the machining assembly 120 is approximately located between the first support portion 133, the second support portion 134 and the third support portion 135, and the first support portion 133 and the second support portion 134 can stably support the machining assembly 120 along the second direction Y. When the machining assembly 120 generates a tipping force due to the inertia of movement, the third support member can support the machining assembly 120 from the third direction Z, which helps to prevent the machining assembly 120 from tipping over, helps to prevent the first support portion 133, the second support portion 134 and the first mounting portion 1310 and the machining assembly 120 from tipping over, and helps to improve the machining accuracy of the machine tool 100.

[0077] The processing space 137 is used to provide a space for the machining component 120 to move.

[0078] Both the first vertical plane and the second vertical plane may be perpendicular to the horizontal plane.

[0079] In some embodiments, the column structure 130 is also provided with a tool magazine accommodating space 138 connected to the processing space 137, and the tool magazine accommodating space 138 is located between the second support portion 134 and the third support portion 135, so that the column structure 130 can be installed with a tool changing magazine 150, thereby expanding the application scope of the column structure 130, so that the machine tool 100 can have a tool changing function, thereby expanding the application scope of the machine tool 100.

[0080] Specifically, the tool magazine accommodating space 138 may be formed by being surrounded by the second mounting portion 1320 , the second supporting portion 134 , the connecting portion 136 and the third supporting portion 135 .

[0081] As an example, the second mounting portion 1320 may be provided with a mounting hole, which may be connected to the tool magazine accommodating space 138 , and the tool changing magazine 150 may be installed in the mounting hole and extend into the tool magazine accommodating space 138 .

[0082] In some embodiments, the third support portion 135 and the second support portion 134 are both located on the first side of the machine tool worktable 140, and the first support portion 133 is located on the second side of the machine tool worktable 140. The first side and the second side are arranged relative to each other, so that the machine tool worktable 140 can be easily moved between the first support portion 133 and the second support portion 134, which helps to extend the moving path of the machine tool worktable 140.
