In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0038] Reference Figure 1 and Figure 2 According to an embodiment of the present application, the machine tool includes: a machine platform 100, a moving module 200, a spindle 300, a workbench 400, a frame 500 and a tool magazine module 600.

[0039] The mobile module 200 is disposed on the machine 100;

[0040] The main shaft 300 is disposed at the driving end of the moving module 200;

[0041] The workbench 400 is disposed on the machine 100 .

[0042] It can be understood that the workbench 400 is used to place parts, the mobile module 200 drives the spindle 300 to approach or move away from the parts on the workbench 400, and the spindle 300 is used to clamp the tool and drive the tool to rotate so that the tool can cut the parts.

[0043] The frame 500 is fixedly mounted on the machine platform 100;

[0044] The tool magazine module 600 is fixedly arranged on the frame 500, and the tool magazine module 600 includes a tool magazine body 610, a shell 620, a driving member 630 and a shielding portion 640. The tool magazine body 610 is arranged in the shell 620, and the shell 620 is provided with an opening 621, and the opening 621 is used for entering and exiting the spindle 300. The driving member 630 is arranged in the shell 620 and is driven to connect to the shielding portion 640 so that the shielding portion 640 covers or opens the opening 621.

[0045] It can be understood that compared with the technical means of setting the tool magazine on the spindle 300 in the prior art, the tool magazine module 600 of the present application is fixed on the machine platform 100 through the frame 500, thereby reducing the load-bearing burden of the spindle 300 and the mobile module 200, and since the weight of the tool magazine module 600 is reduced, the movement of the spindle 300 is more stable.

[0046] It can also be understood that the spindle 300 can enter the housing 620 through the opening 621 on the housing 620 under the driving action of the movable module 200, and can place the tool clamped by the spindle 300 into the tool magazine body 610, or remove the tool on the tool magazine body 610, so as to facilitate the replacement of the tool clamped by the spindle 300. For example, the spindle 300 can release the tool on the spindle 300 to drop the tool on the tool magazine body 610, and then the tool magazine body 610 is rotated to align another tool with the spindle 300 for easy clamping by the spindle 300.

[0047] It should be understood that the tool magazine body 610 is disposed in the housing 620, and a driving member 630 is provided to drive the shielding portion 640, so that the shielding portion 640 can cover or open the opening 621. For example, when the spindle 300 needs to enter the housing 620 for tool change, the driving member 630 drives the shielding portion 640 to open the opening 621 to facilitate the entry of the spindle 300; for another example, when the spindle 300 is processing the parts on the workbench 400, the driving member 630 drives the shielding portion 640 to cover the opening 621, thereby preventing the metal chips generated during the processing of the spindle 300 from splashing onto the tool magazine body 610 in the housing 620, reducing the possibility of metal chips remaining on the tool, ensuring the stability of the spindle 300 clamping the tool, and improving the processing quality.

[0048] It should also be understood that the housing 620 surrounds the tool magazine body 610 , thereby preventing workers from directly hitting the tools in the tool magazine body 610 , thereby improving the safety of the working environment.

[0049] Specifically, the moving module 200 may include one or more of an x-axis moving component, a y-axis moving component, and a z-axis moving component, so that the spindle 300 can move along one or more axes. Further, the moving module 200 includes an x-axis moving component, a y-axis moving component, and a z-axis moving component, so that the spindle 300 can move along three axes.

[0050] Reference Figure 2 and Figure 3 According to some embodiments of the present application, the shielding portion 640 is a plate, and the driving member 630 is used to drive the shielding portion 640 to move in a horizontal direction.

[0051] It can be understood that, in this embodiment, the shielding portion 640 is a plate, and the driving member 630 drives the shielding portion 640 to move horizontally to open or cover the opening 621. For example, the shielding portion 640 is located on one side of the housing 620, and the shielding portion 640 mostly or completely overlaps with the housing 620, and then the driving member 630 drives the shielding portion 640 to move in the horizontal direction to reduce the overlapping portion of the shielding portion 640 and the housing 620, so that the shielding portion 640 covers the opening 621.

[0052] Specifically, the driving member 630 is a cylinder.

[0053] Of course, in other embodiments, the shielding portion 640 may also be a rolling curtain, and the driving member 630 drives the rolling curtain to unfold or reel in, so as to open or shield the opening 621 .

[0054] Reference Figure 2 and Figure 3 According to some embodiments of the present application, the shielding portion 640 is located inside the outer shell 620, the tool magazine module 600 also includes a connecting member 650, the driving member 630 is arranged on the outer wall of the outer shell 620, the connecting member 650 passes through the opening 621, and one end of the connecting member 650 is connected to the driving end of the driving member 630, and the other end is connected to the outer wall of the shielding portion 640.

[0055] It is understandable that the driving member 630 is disposed on the outer side wall of the housing 620 to facilitate the installation of the driving member 630 and reduce the occupied space inside the housing 620. Then, the driving member 630 is connected to the shielding portion 640 located inside the housing 620 through the connecting member 650, and the connecting member 650 is connected to the outer side wall of the shielding portion 640, so that when the driving member 630 drives the shielding portion 640 to shield the opening 621, it is ensured that the side of the shielding portion 640 close to the opening 621 can completely shield the opening 621, so that the connecting member 650 will not affect the sealing effect of the shielding portion 640 relative to the opening 621, and avoid the generation of a gap between the connecting member 650 and the inner wall of the opening 621, so as to ensure the shielding effect of the housing 620 and the shielding portion 640.

[0056] Specifically, the outer wall of the shielding portion 640 can be close to the inner wall of the shell 620, and under the driving action of the driving member 630, the shielding portion 640 can slide relative to the shell 620 to reduce the gap between the shielding portion 640 and the shell 620, thereby further ensuring the shielding effect of the shell 620 and the shielding portion 640.

[0057] According to some embodiments of the present application, the area of ​​the shielding portion 640 is larger than the area of ​​the opening 621 .

[0058] It is understandable that by providing a larger shielding portion 640 , it is ensured that the shielding portion 640 can completely shield the opening 621 .

[0059] Reference Figures 2 to 4 According to some embodiments of the present application, the opening 621 passes through the front wall 623 of the shell 620 facing the main shaft 300 and the top wall 624 of the shell 620, and the shielding portion 640 has a first shielding plate 641 and a second shielding plate 642. The first shielding plate 641 and the second shielding plate 642 are connected and intersectingly arranged, the first shielding plate 641 is parallel to the front wall 623, and the second shielding plate 642 is parallel to the top wall 624.

[0060] It should be noted that the spindle 300 generally has a certain height. In order to reduce production costs and occupy space, the housing 620 can be set to match the height of the tool magazine.

[0061] It can be understood that in order to save the production cost of the shell 620 while ensuring that the spindle 300 can enter the interior of the shell 620 through the opening 621, the opening 621 penetrates the shell 620 towards the front wall 623 of the spindle 300 and the top wall 624 of the shell 620. Specifically, the spindle 300 can enter the interior of the shell 620 through the opening 621 corresponding to the front wall 623, and the opening 621 corresponding to the top wall 624 enables the clamping end of the lower end of the spindle 300 to be located in the shell 620 for tool changing, and enables the upper end of the spindle 300 to pass through the shell 620, so that the spindle 300 does not need to completely enter the interior of the shell 620 for tool changing.

[0062] It can also be understood that in order to ensure the shielding effect of the shielding part 640, the shielding part 640 has a first shielding part 640 and a second shielding part 640 connected to each other, the first shielding part 640 is used to shield the opening 621 part corresponding to the front wall 623, and the second shielding part 640 is used to shield the opening 621 part corresponding to the top wall 624.

[0063] Reference Figure 1According to some embodiments of the present application, a mounting seat 210 is provided at the driving end of the movable module 200, the mounting end of the mounting seat 210 protrudes from a side of the movable module 200 close to the tool magazine module 600, and the spindle 300 is arranged at the mounting end.

[0064] It is understood that the spindle 300 is arranged at the driving end of the mobile module 200 through the mounting seat 210, that is, the mobile module 200 drives the spindle 300 to move through the mounting seat 210. It is understood that the mounting end of the mounting seat 210 protrudes from the side of the mobile module 200 close to the tool magazine module 600, so that the spindle 300 installed at the mounting end protrudes from the mobile module 200, so that the spindle 300 can more easily enter the interior of the housing 620, so as to avoid interference caused by the mobile module 200 in the spindle 300 entering the interior of the housing 620.

[0065] Reference Figure 1 According to some embodiments of the present application, the machine 100 includes a first mounting portion 110 and a second mounting portion 120 , the mobile module 200 and the frame 500 are disposed on the first mounting portion 110 , and the workbench 400 is disposed on the second mounting portion 120 , wherein the first mounting portion 110 is higher than the second mounting portion 120 .

[0066] It can be understood that during the processing, the spindle 300 is located above the part. Therefore, by setting the movable module 200 on the first mounting part 110 with a higher height and setting the workbench 400 on the second mounting part 120 with a lower height, the spindle 300 on the movable module 200 can process the part from high to low.

[0067] It can also be understood that the rack 500 is also disposed on the higher first mounting portion 110. Specifically, the rack 500 is connected to the side wall surface of the first mounting portion 110. Since the first mounting portion 110 has a higher height, a larger mounting area can be provided, so that the rack 500 can be installed more stably.

[0068] Reference Figure 2 and Figure 4 According to some embodiments of the present application, the housing 620 is formed with a mounting hole 622, the frame 500 partially extends along the length direction of the mounting hole 622 to cover the mounting hole 622, and the tool magazine body 610 is fixedly connected to the frame 500 corresponding to the mounting hole 622 and facing the side inside the housing 620.

[0069] It is understandable that in order to save costs, the thickness of the outer shell 620 is designed to be thinner, which is not conducive to the installation of the tool magazine. In the present embodiment, a mounting hole 622 is opened on the outer shell 620, and the mounting hole 622 extends in the horizontal direction. The upper end of the frame 500 also extends in the horizontal direction and corresponds to and shields the mounting hole 622. The tool magazine body 610 is fixed on the frame 500, so as to ensure the shielding effect of the outer shell 620 while ensuring the installation strength of the tool magazine body 610, and prevent metal chips from entering through the mounting hole 622.

[0070] Of course, in other embodiments, the thickness of the outer shell 620 may also be designed to be thicker so that the tool magazine body 610 can be installed on the inner wall of the tool magazine outer shell 620 .

[0071] Reference Figure 1 According to some embodiments of the present application, the spindle 300 includes at least two, and the moving module 200, the tool magazine module 600, and the workbench 400 correspond to the spindle 300 one by one.

[0072] It can be understood that, in the present embodiment, the main spindle 300, the moving module 200, the tool magazine module 600, and the workbench 400 each include two, and they correspond one to one, thereby improving the processing efficiency.

[0073] According to some embodiments of the present application, the tool magazine modules 600 are located on both sides of the machine platform 100 , and the openings 621 of the two tool magazine modules 600 are opposite to each other.

[0074] It is understandable that the tool magazine modules 600 are arranged on both sides of the machine 100, so that the front side of the workbench 400 has a larger space, which is convenient for workers to load and unload materials. In addition, the openings 621 on the housings 620 of the two tool magazine modules 600 are opposite, so that during the process of changing the tool of the spindle 300, it can move horizontally to enter the opening 621, so as to facilitate the tool change of the spindle 300.

[0075] Specifically, the mounting seats 210 on the two moving modules 200 will protrude in opposite directions, so that the mounting positions of the two spindles 300 can be further apart, thereby reducing the impact that may be caused by the simultaneous processing of the two spindles 300.

[0076] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
