Description

Technical Field

[0001] This application relates to the field of machining equipment technology, and in particular to a machine tool. Background Technology

[0002] Machine tools generally consist of a column, spindle, tool magazine, and worktable. The spindle and tool magazine are mounted on the column. The spindle is used to machine the workpiece on the worktable, and it can also access the tool magazine for tool changing. To improve machining efficiency, two spindles and two tool magazines are typically mounted on the column, with one spindle and one tool magazine corresponding to each other. In related technologies, the two tool magazines are located on opposite sides of the column along the x-axis, resulting in a larger machine tool size in the x-axis direction. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a machine tool capable of reducing the size of the machine tool in the x-axis direction.

[0004] The machine tool according to an embodiment of this application includes: a frame, a first tool magazine, and a second tool magazine.

[0005] The frame is provided with a first mounting surface and a second mounting surface; the first mounting surface is parallel to the y-axis direction, the second mounting surface is inclined relative to the y-axis direction, and the angle between the normal of the first mounting surface and the normal of the second mounting surface is α, where α is less than 90°;

[0006] The first tool magazine is disposed on the first mounting surface;

[0007] The second tool magazine is located on the second mounting surface.

[0008] The machine tool according to the embodiments of this application has at least the following beneficial effects: The first mounting surface is parallel to the y-axis direction, and the first tool magazine is mounted on the first mounting surface, located on one side of the machine tool in the x-axis direction. The second mounting surface is inclined relative to the y-axis direction, that is, the second mounting surface is inclined relative to the first mounting surface. After the second tool magazine is mounted on the second mounting surface, the second tool magazine is also inclined relative to the y-axis direction. Therefore, the projection of the second tool magazine on the vertical plane perpendicular to the y-axis direction is relatively small, which can reduce the space occupied by the second tool magazine in the x-axis direction, thereby reducing the size of the machine tool in the x-axis direction. Furthermore, the angle between the normal of the first mounting surface and the normal of the second mounting surface is α, where α is less than 90°. It can be seen that the first and second mounting surfaces face the same side in the x-axis direction. After the second tool magazine is mounted on the second mounting surface, the second tool magazine will be inclined towards the direction closer to the first tool magazine, resulting in a smaller distance between the second and first tool magazines. Therefore, the space occupied by the first and second tool magazines in the x-axis direction can be reduced, further reducing the size of the machine tool in the x-axis direction.

The first support portion is connected to the base, and the frame is connected to the second support portion.

[0037] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0038] In the description of this application, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0039] Reference Figure 1 and Figure 2 The machine tool according to an embodiment of this application includes: a frame 100, a first tool magazine 210, and a second tool magazine 220.

[0040] The frame 100 is provided with a first mounting surface 111 and a second mounting surface 121; the first mounting surface 111 is parallel to the y-axis direction, the second mounting surface 121 is inclined relative to the y-axis direction, and the angle between the normal of the first mounting surface 111 and the normal of the second mounting surface 121 is α, where α is less than 90°.

[0041] The first tool magazine 210 is disposed on the first mounting surface 111;

[0042] The second tool magazine 220 is located on the second mounting surface 121.

[0043] Understandably, the first mounting surface 111 is parallel to the y-axis direction. After the first tool magazine 210 is installed on the first mounting surface 111, it is located on one side of the machine tool in the x-axis direction. The second mounting surface 121 is inclined relative to the y-axis direction, that is, the second mounting surface 121 is inclined relative to the first mounting surface 111. After the second tool magazine 220 is installed on the second mounting surface 121, the second tool magazine 220 is also inclined relative to the y-axis direction. Therefore, the projection of the second tool magazine 220 on the vertical plane perpendicular to the y-axis direction is relatively small, so as to reduce the space occupied by the second tool magazine 220 in the x-axis direction and reduce the size of the machine tool in the x-axis direction. It is also understood that the angle between the normal of the first mounting surface 111 and the normal of the second mounting surface 121 is α, where α is less than 90°. It can be seen that the first mounting surface 111 and the second mounting surface 121 face the same side in the x-axis direction. After the second tool magazine 220 is installed on the second mounting surface 121, the second tool magazine 220 will tilt towards the direction closer to the first tool magazine 210 to reduce the distance between the second tool magazine 220 and the first tool magazine 210. As a result, the space occupied by the first tool magazine 210 and the second tool magazine 220 in the x-axis direction can be reduced, thereby further reducing the size of the machine tool in the x-axis direction.

[0044] Furthermore, referring to Figure 3 The tool holder 221 of the second tool magazine 220 is located on the side of the second tool magazine 220 away from the first tool magazine 210. When the second tool magazine 220 is tilted toward the direction closer to the first tool magazine 210, the tool holder 221 on the second tool magazine 220 tilts toward the front of the machine tool to facilitate the operator to place the tool.

[0045] Specifically, α ranges from 60° to 89°.

[0046] Reference Figure 1 and Figure 2 According to some embodiments of this application, the frame 100 includes a first mounting frame 110 and a second mounting frame 120. The first mounting frame 110 and the second mounting frame 120 are independently or integrally arranged. The first mounting frame 110 is provided with a first mounting surface 111, and the second mounting frame 120 is provided with a second mounting surface 121.

[0047] It is understood that, in some embodiments, by mounting the first tool magazine 210 and the second tool magazine 220 on the independently provided first mounting bracket 110 and second mounting bracket 120 respectively, the first tool magazine 210 and the first mounting bracket 110 can be assembled as a module, and the second tool magazine 220 and the second mounting bracket 120 can be assembled as a module, thereby facilitating the installation of the first tool magazine 210 and the second tool magazine 220. In other embodiments, the first mounting bracket 110 and the second mounting bracket 120 are integrally provided, which can improve the structural strength of the frame 100.

[0048] Reference Figure 2 According to some embodiments of this application, a gap 130 is formed between the second mounting bracket 120 and the first mounting bracket 110.

[0049] It is understandable that creating a gap 130 between the first mounting bracket 110 and the second mounting bracket 120 provides a certain installation space for the second tool magazine 220, thus preventing the second tool magazine 220 from colliding with the first mounting bracket 110.

[0050] Reference Figure 2 According to some embodiments of this application, a notch 112 is formed on the side of the first mounting bracket 110 near the second mounting bracket 120.

[0051] It is understandable that a notch 112 is formed on the side of the first mounting bracket 110 near the second mounting bracket 120 to reduce the space occupied by the first mounting bracket 110 near the second mounting bracket 120, thereby providing more installation space for the second tool magazine 220.

[0052] Specifically, the projections of the first mounting bracket 110 and the second tool magazine 220 on the horizontal plane do not overlap.

[0053] Reference Figure 1 and Figure 2 According to some embodiments of this application, it also includes a column 300, a first spindle 410, a second spindle 420, a first connecting structure 510, and a second connecting structure 520; the frame 100 is disposed on the column 300; the first connecting structure 510 and the second connecting structure 520 are both movable along the height direction and disposed on the column 300, the first spindle 410 is disposed on the first connecting structure 510, the second spindle 420 is disposed on the second connecting structure 520, and the first spindle 410 can enter the first tool magazine 210 for tool changing, and the second spindle 420 can enter the second tool magazine 220 for tool changing.

[0054] Understandably, the first spindle 410 is connected to the column 300 via the first connecting structure 510. Since the first connecting structure 510 can move relative to the column 300 in the height direction, it can drive the first spindle 410 to move in the height direction, allowing the first spindle 410 to approach or move away from the workpiece placed below it, and facilitating its entry into the first tool magazine 210 for tool changing. Similarly, the second spindle 420 is connected to the column 300 via the second connecting structure 520. Since the second connecting structure 520 can move relative to the column 300 in the height direction, it can drive the second spindle 420 to move in the height direction, allowing the second spindle 420 to approach or move away from the workpiece placed below it, and facilitating its entry into the second tool magazine 220 for tool changing.

[0055] Specifically, refer to Figure 1 The lifting drive mechanism 810 drives the first connecting structure 510 and the second connecting structure 520 to lift the first main shaft 410 and the second main shaft 420. For example, the lifting drive mechanism 810 includes a slide rail, a slide block, and a screw module. The column 300 is provided with multiple slide rails extending along the height direction. Both the first connecting structure 510 and the second connecting structure 520 are provided with slide blocks, which slide in cooperation with the slide rails. The two screw modules drive the first connecting structure 510 and the second connecting structure 520 respectively.

[0056] Reference Figure 5 According to some embodiments of this application, the second connecting structure 520 is formed with a third mounting surface 521, the second main shaft 420 is disposed on the third mounting surface 521, the third mounting surface 521 is inclined relative to the y-axis direction, and the normal of the third mounting surface 521 is parallel to or overlaps with the normal of the second mounting surface 121.

[0057] It is understandable that the third mounting surface 521 is also inclined relative to the y-axis direction, and the normal of the third mounting surface 521 is parallel or overlaps with the normal of the second mounting surface 121. It can be seen that the second spindle 420 mounted on the third mounting surface 521 is also inclined relative to the y-axis direction, and the angle of inclination of the second spindle 420 relative to the y-axis is consistent with that of the second tool magazine 220, so that the second spindle 420 can enter the second tool magazine 220.

[0058] Reference Figure 1 and Figure 3 According to some embodiments of this application, it also includes a base 600, and the column 300 includes a first support portion 310 and a second support portion 320 connected to each other. The first support portion 310 is connected to the base 600, and the frame 100 is connected to the second support portion 320. The dimension of the first support portion 310 along the x-axis is larger than the dimension of the second support portion 320 along the x-axis.

[0059] It is understandable that the second support part 320 is connected to the base 600 through the first support part 310. The second support part 320 is used to fix the frame 100. The first support part 310 is located below the second support part 320. Since the dimension of the first support part 310 along the x-axis is larger than the dimension of the second support part 320 along the x-axis, the column 300 has better stability and structural strength.

[0060] Reference Figure 3 and Figure 4 According to some embodiments of this application, the first support portion 310 is provided with grooves 311 on both sides along the x-axis direction, the groove wall of the groove 311 is provided with a first threaded hole 312, and the base 600 is provided with a second threaded hole 610 on the side connected to the first support portion 310. The first threaded hole 312 and the second threaded hole 610 are used for threaded connection of fasteners to fix the base 600 and the first support portion 310.

[0061] It is understood that fasteners are passed through and screwed into the first threaded hole 312 and the second threaded hole 610 to secure the base 600 and the first support portion 310. It should be understood that by creating a groove 311 on the first support portion 310 and a first threaded hole 312 on the groove wall of the groove 311, the space required for installation of the first support portion 310 and the base 600 can be reduced. It eliminates the need for an additional connecting plate on the first support portion 310 for installation with the base 600, thus avoiding increasing the dimensions of the machine tool in the x-axis direction. Furthermore, the groove 311 can accommodate the fasteners, preventing them from protruding outwards.

[0062] Specifically, the groove 311 extends along the height direction and penetrates the upper side of the first support portion 310. Since the dimension of the first support portion 310 along the x-axis is larger than the dimension of the second support portion 320 along the x-axis, the groove 311 can penetrate only the first support portion 310. After the groove 311 penetrates the first support portion 310, it facilitates the fastener to pass through the first threaded hole 312 and the second threaded hole 610 from top to bottom, thereby facilitating the locking of the fastener.

[0063] Specifically, there are multiple first threaded holes 312 and second threaded holes 610, and the first threaded holes 312 and second threaded holes 610 correspond one-to-one.

[0064] Reference Figure 4 According to some embodiments of this application, the first support portion 310 and the second support portion 320 are integrally formed.

[0065] It is understandable that by integrally molding the first support part 310 and the second support part 320, production costs can be reduced and the structural strength of the column 300 can be improved.

[0066] Reference Figure 1 According to some embodiments of this application, it also includes a first worktable 710 and a second worktable 720. The first worktable 710 is located below the first spindle 410 and can move horizontally relative to the first spindle 410. The second worktable 720 is located below the second spindle 420 and can move horizontally relative to the second spindle 420.

[0067] It is understandable that the first spindle 410 corresponds to the first worktable 710. The first spindle 410 can process the workpiece on the first worktable 710, and the first worktable 710 can move horizontally relative to the first spindle 410 to adjust the relative position of the workpiece on the first worktable 710 and the first spindle 410, which is beneficial for the first spindle 410 to process the workpiece. Similarly, the second spindle 420 corresponds to the second worktable 720. The second spindle 420 can process the workpiece on the second worktable 720, and the second worktable 720 can move horizontally relative to the second spindle 420 to adjust the relative position of the workpiece on the second worktable 720 and the second spindle 420, which is beneficial for the second spindle 420 to process the workpiece. Therefore, the first spindle 410 and the second spindle 420 are respectively provided with the first worktable 710 and the second worktable 720, so that the first spindle 410 and the second spindle 420 can process independently without affecting each other.

[0068] Specifically, a horizontal drive mechanism 820 connects the first worktable 710 and the second worktable 720 to drive them to move horizontally. For example, the horizontal drive mechanism 820 includes one or both of an x-axis lead screw module and a y-axis lead screw module.

[0069] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
