Technical Field

[0001] This invention relates to the field of machine tool technology, and more particularly to a horizontal machine tool. Background Technology

[0002] After a workpiece is clamped once on a machining tool, the digital control system can control the machine tool to automatically select and change cutting tools according to different machining processes, automatically change the machine tool spindle speed, feed rate, and the movement trajectory of the cutting tool relative to the workpiece, as well as other auxiliary functions, to complete the machining of multiple surfaces of the workpiece in sequence. Horizontal machining tools have the advantages of cost saving, space occupancy, and high processing efficiency, and are therefore widely used in the processing industry.

[0003] The existing horizontal machining center has a separate worktable and tool magazine, resulting in a loose machine tool configuration, large equipment space occupation, and the worktable and tool magazine require separate drive mechanisms. The drive equipment layout occupies a lot of space, and the separate drive mechanisms need to be controlled separately. This leads to complicated operation, reduced workpiece processing efficiency, and the possibility of motion interference, resulting in increased manufacturing and operating costs.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example:

[0025] like Figure 1-3 The image shows a horizontal machining center provided in this embodiment, including a B-axis rotary assembly 1. The B-axis rotary assembly 1 has a machining surface 2 and a tool magazine surface 3 facing different directions. Both the machining surface 2 and the tool magazine surface 3 are parallel to the B-axis and can rotate around the B-axis simultaneously. A tool magazine 4 is provided on the tool magazine surface 3. The axis of the tool in the tool magazine 4 is perpendicular to the tool magazine surface 3. A worktable 5 is provided on the machining surface 2. The rotation axis of the worktable 5 is perpendicular to the machining surface 2.

[0026] Specifically, in this embodiment, both the worktable 5 and the tool magazine 4 can rotate freely around the B-axis 360°. The interference area between the worktable 5 and the tool magazine 4 and other components is small, and the degree of machining freedom is high, thereby promoting the improvement of production efficiency. The worktable 5 can be equipped with automated tooling fixtures, tooling mother plates, tooling daughter plates, and automated material changing mechanisms such as robots or manipulators to realize automatic loading and unloading. The tool magazine 4 can be equipped with automated tool changing mechanisms such as robots or manipulators, and the automated tool changing mechanism can share and reuse the same mechanism with the automated material changing mechanism.

[0027] This invention discloses a horizontal machining center with a shared B-axis rotation design for the worktable and tool magazine. This design results in a compact machine tool configuration, effectively reducing the space required for equipment layout. Furthermore, the worktable and tool magazine do not require separate drive units, saving space. Simultaneously, the worktable and tool magazine can be driven to rotate, significantly improving the ease of control. Moreover, the shared drive unit for both the worktable and tool magazine avoids the potential for motion interference that would result from separate drive units. The shared B-axis for the worktable and tool magazine reduces manufacturing and operating costs while increasing workpiece machining efficiency.

[0028] Preferred, such as Figure 1 As shown, it also includes an A-axis rotary assembly 6, which includes multiple parallel spindles 61; multiple tool sets 7 are provided on the tool magazine surface 3, and the tool sets 7 contain the tools; multiple worktables 5 are provided on the machining surface 2; the positions of the spindles 61, tool sets 7, and worktables 5 correspond one-to-one, which facilitates the cooperation between the spindles 61 and tool sets 7 to complete tool picking and tool changing actions, and allows the spindles 61 to use the tools to machine the workpiece on the worktables 5 after picking up the tools, ensuring accurate positioning of the spindles 61 and the tools in the tool sets 7 during tool picking and changing. This ensures the positioning accuracy of the spindle 61 and the tool when the spindle 61 picks up and changes tools from the tool set 7. Therefore, it guarantees the positional accuracy of the tool on the spindle 61 after tool change. The corresponding position of the spindle 61 and the worktable 5 ensures the machining accuracy of the tool on the spindle 61 on the workpiece on the worktable 5, guaranteeing the workpiece machining quality to meet production requirements. Setting up multiple spindles 61 and multiple tool sets 7 enables large-scale tool changing and picking operations, as well as the simultaneous machining of large batches of workpieces. This increases the production volume of each batch, improves batch production efficiency, and ultimately increases economic benefits.

[0029] Preferably, the tool assembly 7 includes at least two tool holders 71, the opening directions of the two tool holders 71 being opposite. The tool holders 71 are used to clamp the tool holder to ensure the stability of the tool holder and the tool on the tool holder, facilitating the tool removal action in conjunction with the spindle 61.

[0030] Preferred, such as Figure 1As shown, multiple spindles 61 are arranged along the Y-axis, and the axis of each spindle 61 is parallel to the X-axis. The spindles 61 are arranged along the Y-axis, which is the direction of the B-axis rotation axis. This facilitates positioning with the tools within the tool assembly 7, enabling precise tool picking and changing. Precise tool picking and changing, along with accurate tool positioning on the spindle 61, improves the positioning accuracy of the tool tip relative to the workpiece, thereby achieving high-precision machining of the workpiece.

[0031] Preferred, such as Figure 1-3 As shown, it also includes a bed 8, a column 9, and a slide saddle 10; the B-axis rotary assembly 1 further includes a B-axis rotary table 11, which is mounted on the bed 8 and can move along the X-axis; the column 9 is mounted on the bed 8 and can move along the Z-axis; the slide saddle 10 is mounted on the column 9 and can move along the Y-axis; the slide saddle 10 is equipped with the A-axis rotary assembly 6. In this embodiment, the top of the bed 8 is provided with a bed guide rail arranged along the Z-axis direction, and the bottom of the column 9 is provided with a column slider. The column 9 is mounted on the bed guide rail via the column slider and can slide along the bed guide rail; the side wall of the column 9 near the slide saddle 10 is provided with a column guide rail arranged along the Y-axis direction, and the slide saddle 10 is equipped with a slide saddle slider. The slide saddle 10 is mounted on the column 9 via the slide saddle slider and can slide along the column guide rail. The cooperation between the column 9, the bed 8, and the slide saddle 10 allows the spindle 61 mounted on the slide saddle 10 to adjust its height relative to the bed 8 along the Y-axis (vertical direction) and to move its position along the Z-axis to adjust the distance between it and the worktable 5. The arrangement of the column 9, the bed 8, and the slide saddle 10 improves the flexibility and convenience of adjusting the position of the spindle 61.

[0032] Preferably, the system further includes a B-axis support 12, which is movable along the X-axis, and the B-axis turntable 11 is mounted on the B-axis support 12. In this embodiment, the B-axis support 12 is connected to a ball screw drive mechanism, which drives the B-axis support 12 to move along the X-axis, thereby driving the B-axis turntable 11 to move along the X-axis. This causes the B-axis rotary assembly 1 to move along the X-axis, moving closer to or further away from the A-axis rotary assembly 6, thus adjusting the distance between the two. The B-axis support 12 improves the flexibility of adjusting the distance between the B-axis rotary assembly 1 and the A-axis rotary assembly 6.

[0033] Preferably, the B-axis support 12 includes a support portion 13, a mating portion 14 disposed opposite to the support portion 13, and a connecting portion 15 disposed between the support portion 13 and the mating portion 14;

[0034] The B-axis rotary assembly 1 also includes a workpiece C-axis housing 16. The machining surface 2 and the tool magazine surface 3 are both provided on the workpiece C-axis housing 16. The B-axis rotary table 11 is provided on the support part 13. One end of the workpiece C-axis housing 16 is mounted on the B-axis rotary table 11, and the other end is rotatably connected to the mating part 14. The workpiece C-axis housing 16 can rotate around the B-axis. The workpiece C-axis housing 16 has a polyhedral structure. In this embodiment, the workpiece C-axis housing 16 is a square housing structure. The square housing structure includes four sides, one of which is a machining surface 2, on which a worktable 5 is mounted. The other three sides are tool magazine surfaces 3, on which tool magazines 4 are mounted. The mating part 14 is used to provide top support for the B-axis rotary assembly 1. The arrangement and cooperation of the connecting part 15 with the supporting part 13 and the mating part 14 can not only enhance the structural rigidity of the B-axis rotary assembly 1, but also provide stable support for the rotation of the B-axis rotary assembly 1, so as to ensure the stability of the B-axis rotary assembly 1 during rotation.

[0035] Preferably, the bed 8 is provided with an auxiliary positioning part 17, the auxiliary positioning part 17 is provided with an auxiliary guide rail 18, and the bed 8 is provided with an X-axis guide rail 19. The auxiliary guide rail 18 is parallel to the X-axis guide rail 19 and is positioned differently on the Y-axis from the X-axis guide rail 19. The connecting part 15 is mounted on the auxiliary guide rail 18 via a first slider 20, and the supporting part 13 is mounted on the X-axis guide rail 19 via a second slider 21. By setting the second slider 21 and the X-axis guide rail 19, the B-axis support 12 can move along the X-axis guide rail 19, i.e., the C-axis housing 16 can move along the X-axis guide rail 19, thereby adjusting the distance between the worktable 5 and the tool magazine 4 and the A-axis rotary assembly 6, improving the convenience of adjusting the position between the worktable 5 and the tool magazine 4 and the spindle 61. The auxiliary guide rail 18 and the first slider 20 cooperate with the X-axis guide rail 19 and the second slider 21 to assist the B-axis support 12 and the B-axis rotary assembly 1 in moving along the X-axis guide rail 19.

[0036] Preferably, the workpiece C-axis housing 16 is equipped with a C-axis power assembly for driving the worktable 5. The C-axis power assembly can provide driving force for the rotation of the worktable 5.

[0037] The specific working process of a horizontal machining center disclosed in this invention is as follows:

[0038] First, the workpiece to be processed is mounted on the worktable 5 using the equipped automated tooling fixture. External force drives the support 13 to slide along the X-axis guide rail 19, causing the B-axis rotary assembly 1 to slide closer to or further away from the A-axis rotary assembly 6 along the X-axis guide rail 19. The positions of the B-axis rotary assembly 1 and the A-axis rotary assembly 6 are adjusted. Then, the B-axis rotary table 11 is driven to rotate. The B-axis rotary table 11 drives the workpiece C-axis housing 16 to rotate around the B-axis. The tool magazine surface 3 on the C-axis housing rotates accordingly, meaning the tool magazine 4 rotates as well. The tool magazine 4 rotates to a direction that matches the spindle 61 of the A-axis rotary assembly 6. Finally, the column is adjusted along the Z-axis. Position 9, adjust the position of slide saddle 10 along the Y-axis, adjust the spindle 61 to match the tool in tool magazine 4, rotate the spindle 61 to remove the tool, drive the B-axis rotary table 11 and workpiece C-axis housing 16 to rotate again, rotate the worktable 5 to face the spindle 61, adjust the position of column 9 and slide saddle 10, and at the same time adjust the position of B-axis rotary assembly 1 so that the worktable 5 corresponds to the position of spindle 61. Finally, the C-axis power assembly in C-axis housing 16 drives the worktable 5 to rotate, the worktable 5 drives the workpiece to rotate, and the tool on spindle 61 rotates around the A-axis to process the workpiece.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
