[0022] 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.

[0023] 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.

[0024] Reference Figures 1 to 3 The machine tool according to an embodiment of this application includes: Rack 100 The slide table 200 is movable along the x-axis direction and is mounted on the frame 100. The slide table 200 can slide to the processing position 210 or the waiting position 220. At least two slide tables 200 are provided. The x-axis drive module 300 is mounted on the frame 100 and is connected to the slide 200. The worktable 400 is movable along the y-axis direction and is set on the slide 200. The number of worktables 400 corresponds one-to-one with the number of slides 200, and each slide 200 is slidably connected to a worktable 400. The y-axis drive module 500 is mounted on the slide 200 and is connected to the worktable 400. The spindle 600 is vertically mounted on the frame 100 and is located above the worktable 400 along its x-axis movement path. When the slide 200 slides to the processing position 210, the corresponding worktable 400 is located below the spindle 600. When the slide 200 slides to the waiting position 220, the corresponding worktable 400 is offset from the spindle 600 in the x-axis direction. The protective cover 700 is disposed between two adjacent slides 200. One of the two adjacent slides 200 is fixedly connected to one end of the protective cover 700, and the other slides are slidably engaged with the other end of the protective cover 700. The protective cover 700 is disposed above the x-axis drive module 300.

[0025] Understandably, the x-axis drive module 300 can drive the slide 200 corresponding to the worktable 400 carrying unprocessed parts to the processing position 210, placing the worktable 400 below the spindle 600, whereby the spindle 600 processes the parts on the worktable 400. Simultaneously, the x-axis drive module 300 can also drive the slide 200 corresponding to the worktable 400 carrying processed parts to the waiting position 220, thus separating the worktable 400 from the spindle 600. This facilitates the unloading of processed parts by workers or robots, and the loading of another unprocessed part. After the spindle 600 completes the processing of the part, the x-axis drive module 300 moves the slide 200 corresponding to the worktable 400 carrying processed parts from the processing position 210 to the waiting position 220, and moves the slide 200 corresponding to the worktable 400 carrying another unprocessed part from the waiting position 220 to the processing position 210. Therefore, while the spindle 600 is processing parts on one of the worktables 400, workers or robots can load and unload materials on the other worktable 400 to improve production efficiency.

[0026] It is also understandable that the x-axis drive module 300 drives the slide 200 to move along the x-axis direction, thereby driving the y-axis drive module 500 and the worktable 400 on the slide 200 to move along the x-axis direction. The y-axis drive module 500 drives the worktable 400 to move along the y-axis direction, so that the worktable 400 can move along the x-axis and y-axis directions. Furthermore, each worktable 400 has an independent x-axis drive module 300 and y-axis drive module 500, so the processing between the worktables 400 is not affected by each other.

[0027] It is also understandable that the protective cover 700 can protect the x-axis drive module 300 below it, reducing the impact of cutting fluid on the x-axis drive module 300. When two adjacent worktables 400 move relative to each other in the x-axis direction, that is, when two adjacent slides 200 move relative to each other in the x-axis direction, since one end of the protective cover 700 is fixedly connected to the slide 200 and the other end can movably pass through another slide 200, the protective cover 700 can move relative to the slide 200 to ensure that the protective cover 700 does not affect the relative movement of the slide 200 in the x-axis direction, and ensures the protective effect of the protective cover 700. At the same time, since the protective cover 700 is connected to the slide 200, and the y-axis drive module 500 is set on the slide 200, and the drive worktable 400 moves relative to the slide 200 in the y-axis direction, the adjacent worktables 400 are not interfered with by the protective cover 700 when moving relative to each other in the y-axis direction.

[0028] Reference Figure 1 and Figure 2 According to some embodiments of this application, at least one slide 200 is formed with a sliding channel 230 extending along the x-axis direction, and a protective cover 700 is movably disposed within the sliding channel 230.

[0029] It is understandable that the protective cover 700 is installed in the sliding channel 230. When two adjacent slides 200 move relative to each other in the x-axis direction, the protective cover 700 slides in the sliding channel 230 so as to receive part of the protective cover 700 through the sliding channel 230 and guide the movement of the protective cover 700 through the sliding channel 230.

[0030] Specifically, the sliding channel 230 is equipped with anti-friction pads to prevent the protective cover 700 from directly rubbing against the inner wall of the sliding channel 230, thereby improving the service life of the protective cover 700.

[0031] Specifically, the distance between two adjacent slides 200 along the x-axis does not exceed the length of the protective cover 700 along the x-axis, so as to prevent the protective cover 700 from leaving the sliding channel 230.

[0032] Specifically, the sliding channel 230 runs through both ends of the slide table 200.

[0033] It is understandable that the two ends of the sliding channel 230 pass through both ends of the slide table 200 in the x-axis direction, which facilitates the installation of the protective cover 700 and allows the slide tables 200 in each position to be made with the same shape. In addition, in some cases, one end of the sliding channel 230 is used to insert the protective cover 700, and the other end of the sliding channel 230 can be used for the protective cover 700 to exit. For example, when the two slide tables 200 are close to each other in the x-axis direction, the protective cover 700 can exit from one end of the sliding channel 230 to avoid the sliding channel 230 interfering with the movement of the protective cover 700.

[0034] Reference Figure 3 According to some embodiments of this application, the slide table 200 includes an upper seat 240 and a lower seat 250, the upper seat 240 and the lower mold are detachably connected, and a sliding channel 230 is defined between the upper seat 240 and the lower seat 250.

[0035] Understandably, when the upper seat 240 and the lower seat 250 are detached, the sliding channel 230 opens to facilitate the installation of the protective cover 700. When the upper seat 240 and the lower mold are connected, the sliding channel 230 is formed between the upper seat 240 and the lower seat 250 to limit the protective cover 700. The detachable connection between the upper seat 240 and the lower seat 250 facilitates the installation of the protective cover 700.

[0036] Reference Figure 3 According to some embodiments of this application, the upper seat 240 is provided with a through groove 241, and the lower seat 250 is provided with a protrusion 251. The protrusion 251 is inserted into the through groove 241, the lower end face of the upper seat 240 abuts against the upper end face of the lower seat 250, and a sliding channel 230 is formed between the outer side of the protrusion 251 and the groove wall of the through groove 241.

[0037] It is understandable that both the through groove 241 and the protrusion 251 extend along the x-axis. After the upper seat 240 and the lower seat 250 are connected, the protrusion 251 of the lower seat 250 is inserted into the through groove 241 of the upper mold. The outer side of the protrusion 251 is spaced apart from the groove wall of the through groove 241, and the lower end face of the upper seat 240 and the upper end face of the lower seat 250 abut against each other to form a sliding channel 230 that passes through the slide table 200 in the x-axis direction. The cross-section of the sliding channel 230 is roughly "U" shaped. Correspondingly, the cross-section of the protective cover 700 is also roughly "U" shaped, so as to achieve a better splash prevention effect and flow guiding effect. The "U" shaped sliding channel 230, together with the "U" shaped protective cover 700, can improve the limiting effect of the protective cover 700.

[0038] Reference Figure 1 and Figure 2 According to some embodiments of this application, two slides 200 are provided, and one protective cover 700 is provided. The two slides 200 are distributed along the x-axis direction.

[0039] It is understood that, in a specific embodiment, there are two slides 200 distributed along the x-axis, and two worktables 400 are also provided. Each slide 200 is equipped with a worktable 400, and there is one protective cover 700. One end of the protective cover 700 is fixedly connected to one of the slides 200, and the other end of the protective cover 700 is slidably inserted through the other slide 200.

[0040] Reference Figure 1 and Figure 2 According to some embodiments of this application, there are two waiting positions 220, located on both sides of the processing position 210 in the x-axis direction.

[0041] It is understandable that there are two waiting positions 220, located on both sides above the x-axis of the processing position 210. Each waiting position 220 corresponds to a slide 200. That is, each time the worktable 400 needs to load or unload, the corresponding slide 200 will move along the x-axis to the corresponding waiting position 220. Thus, the two slides 200 will not interfere with each other when they move in the x-axis direction.

[0042] Reference Figure 2 and Figure 3 According to some embodiments of this application, the x-axis drive module 300 includes an x-axis lead screw assembly 310 and a guide rail 320. Both the x-axis lead screw assembly 310 and the guide rail 320 are fixedly connected to the frame 100. The x-axis lead screw assembly 310 drives a slide 200, which is slidably disposed on the guide rail 320.

[0043] It is understandable that the x-axis lead screw assembly 310 drives the slide table 200 to slide along the x-axis direction, and the guide rail 320 guides the movement of the slide table 200.

[0044] Reference Figure 2 and Figure 3 According to some embodiments of this application, the x-axis drive module 300 corresponds one-to-one with the worktable 400, and at least two x-axis lead screw assemblies 310 are distributed along the y-axis direction.

[0045] It is understood that the x-axis lead screw assembly 310 is distributed along the y-axis direction so as to utilize the space in the y-axis direction and reduce the space occupied in the x-axis direction, thereby reducing the width of the worktable 400 module of this application.

[0046] Reference Figure 3According to some embodiments of this application, the x-axis lead screw assembly 310 includes a motor 311, a lead screw 312, and a nut seat 313. The motor 311 drives and connects to the lead screw 312. The nut seat 313 is slidably disposed on the lead screw 312 and connected to the slide table 200. The motor 311 is disposed at the end of the frame 100 and exposed outside the protective cover 700. The lead screw 312 passes through the lower part of the protective cover 700 or the lower part of the slide table 200.

[0047] Understandably, motor 311 drives lead screw 312 to rotate. Lead screw 312 is threadedly connected to nut seat 313. The rotation of lead screw 312 causes nut seat 313 to move along the x-axis, and nut seat 313 causes slide table 200 to move along the x-axis. Motor 311 is located at one end of frame 100 along the x-axis, away from worktable 400. Even if motor 311 is exposed outside protective cover 700, cutting fluid can be prevented from falling on motor 311. Lead screw 312 passes under protective cover 700 or slide table 200, and is shielded by protective cover 700 or slide table 200 to prevent cutting fluid from falling on lead screw 312.

[0048] Reference Figure 1 According to some embodiments of this application, it also includes a z-axis drive module 800 and a tool magazine 900. The z-axis drive module 800 is connected to the spindle 600, and the tool magazine 900 is disposed on one side of the spindle 600, allowing the spindle 600 to enter the tool magazine 900.

[0049] Understandably, the Z-axis drive module 800 can drive the spindle 600 to move up and down to get closer to the worktable 400 to process the parts on the worktable 400. It can also drive the spindle 600 into the tool magazine 900 to change tools.

[0050] 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.
