Worktable module and machine tool

Abstract

The application discloses a workbench module and a machine tool. The workbench module comprises a bearing table, a y-axis driving module, a saddle, an x-axis driving module, a base and a first protective cover. The first protective cover can protect the x-axis driving module below the first protective cover, and the adjacent saddles also move relatively in the x-axis direction. Since one end of the first protective cover is fixedly connected with a saddle and the other end is movably arranged through another saddle, the first protective cover can move relatively to the saddles, so that the first protective cover does not affect the relative movement of the saddles in the x-axis direction and the protection effect of the first protective cover is ensured. Since the first protective cover is connected with the saddles and the y-axis driving module is arranged on the saddles and drives the bearing table to move relatively to the saddles along the y-axis direction, the adjacent bearing tables are not interfered by the first protective cover when moving relatively in the y-axis direction. In addition, the second protective cover can protect the y-axis driving module and reduce the influence of cutting fluid on the y-axis driving module.

Description

Technical Field

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

[0002] During the machining process, the adjacent parts to be processed need to be placed on the support table first, and the spindle processes the parts on the worktable.

[0003] In related technologies, the carrier table and the spindle can move relative to each other in the x, y, and z axes. During the machining process, the spindle needs to spray cutting fluid onto the carrier table. Therefore, a drive module is generally not set up to connect to the carrier table. That is, the x-axis drive module, y-axis drive module and z-axis drive module are all connected to drive the spindle to drive the spindle to move in the x, y, and z axes.

[0004] To improve the machining efficiency of machine tools, multiple sets of carrier tables and spindles are set up to process parts on multiple carrier tables simultaneously through multiple spindles. However, the x-axis drive module, y-axis drive module, and z-axis drive module are all connected to the spindle, which makes the frame used to connect the spindle too heavy. As a result, the x-axis drive module is connected to the carrier table. In order to reduce the impact of cutting fluid on the x-axis drive module connected to the carrier table, a first protective cover that can extend and retract along the x-axis direction is set between two adjacent carrier tables to shield the x-axis drive module below. However, this design prevents multiple carrier tables from moving relative to each other in the y-axis direction. The first protective cover interferes with the movement of adjacent carrier tables in the y-axis direction. Therefore, this design cannot connect the y-axis drive module to the carrier table as well, and cannot further reduce the load on the frame connected to the spindle. Utility Model Content

[0005] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a worktable module, in which both the x-axis drive module and the y-axis drive module can be connected to the support platform, and the first protective cover does not interfere with the movement of the support platform in the y-axis direction.

[0006] This application also proposes a machine tool having the above-mentioned worktable module.

[0007] The workbench module according to a first aspect embodiment of this application includes: a support platform, a y-axis drive module, a saddle, an x-axis drive module, a base, and a first protective cover.

[0008] Multiple support platforms are provided.

[0009] Multiple y-axis drive modules are provided, and each y-axis drive module is connected to one of the support platforms.

[0010] Multiple saddles are provided, and each saddle is fixed with a y-axis drive module.

[0011] Multiple x-axis drive modules are provided, and each x-axis drive module is connected to one of the saddles.

[0012] The base is fixedly connected to the x-axis drive module;

[0013] The first protective cover is provided in multiple ways, with one first protective cover provided between two adjacent saddles. One end of the first protective cover is fixedly connected to one of the saddles, and the other end of the first protective cover is movably passed through the other saddle. The first protective cover is provided above the x-axis drive module.

[0014] Multiple second protective covers are provided, with one second protective cover connected to each of the saddles, and the second protective covers are positioned above the y-axis drive module.

[0015] The worktable module according to the first aspect embodiment of this application has at least the following beneficial effects: the x-axis drive module drives the saddle to move along the z-axis direction, thereby driving the y-axis drive module and the carrier table on the saddle to move along the x-axis direction. The y-axis drive module drives the carrier table to move along the y-axis direction, thus enabling the carrier table to move along both the x-axis and y-axis directions. Furthermore, each carrier table has an independent x-axis drive module and y-axis drive module, so the processing between carrier tables is independent of each other. Machine tools using the worktable module of this application can process different parts simultaneously or allow several parts to have different processing progress. The first protective cover can protect the x-axis drive module below it, reducing the impact of cutting fluid on the x-axis drive module. When two adjacent carrier tables move relative to each other in the x-axis direction, adjacent saddles also move relative to each other in the x-axis direction. Since one end of the first protective cover is fixedly connected to the saddle, and the other end can movably pass through another saddle, the first protective cover can move relative to the saddle to ensure that the first protective cover does not affect the relative movement of the saddle in the x-axis direction and to ensure the protective effect of the first protective cover. Meanwhile, since the first protective cover is connected to the saddle, and the y-axis drive module is mounted on the saddle, and the drive platform moves relative to the saddle along the y-axis direction, the adjacent platforms are not interfered with by the first protective cover when they move relative to each other in the y-axis direction. Furthermore, the second protective cover can protect the y-axis drive module and reduce the impact of the cutting fluid on the y-axis drive module.

[0016] According to some embodiments of this application, at least one of the saddles forms a sliding channel extending along the x-axis, and the first protective cover is movably inserted into the sliding channel.

[0050] Reference Figures 1 to 5 The workbench module according to the first aspect of this application includes: a support platform 100, a y-axis drive module 200, a saddle 300, an x-axis drive module 400, a base 500, and a first protective cover 600.

[0051] There are multiple support platforms, each with a capacity of 100.

[0052] Multiple y-axis drive modules 200 are provided, and each y-axis drive module 200 drives and connects to a support platform 100.

[0053] Multiple saddles 300 are provided, and each saddle 300 is fixed with a y-axis drive module 200.

[0054] There are multiple x-axis drive modules 400, and each x-axis drive module 400 is connected to a saddle 300.

[0055] Base 500, fixedly connected to x-axis drive module 400;

[0056] Multiple first protective covers 600 are provided. One first protective cover 600 is provided between two adjacent saddles 300. One end of the first protective cover 600 is fixedly connected to one of the saddles 300, and the other end of the first protective cover 600 is movably inserted through another saddle 300. The first protective cover 600 is provided above the x-axis drive module 400.

[0057] Multiple second protective covers 700 are provided, with one second protective cover 700 connected to each saddle 300. The second protective cover 700 covers the top of the y-axis drive module 200.

[0058] It is understood that the x-axis drive module 400 drives the saddle 300 to move along the z-axis direction, thereby driving the y-axis drive module 200 and the carrier table 100 on the saddle 300 to move along the x-axis direction. The y-axis drive module 200 drives the carrier table 100 to move along the y-axis direction, thus enabling the carrier table 100 to move along both the x-axis and y-axis directions. Furthermore, each carrier table 100 has an independent x-axis drive module 400 and y-axis drive module 200 for driving. As a result, the machining processes between the carrier tables 100 are not affected by each other. Machine tools using the worktable module of this application can process different parts simultaneously or enable several parts to have different machining progress. The first protective cover 600 can protect the x-axis drive module 400 below it, reducing the impact of cutting fluid on the x-axis drive module 400. When two adjacent support platforms 100 move relative to each other in the x-axis direction, the adjacent saddles 300 also move relative to each other in the x-axis direction. Since one end of the first protective cover 600 is fixedly connected to the saddle 300 and the other end can be movably inserted through another saddle 300, the first protective cover 600 can move relative to the saddle 300 to ensure that the first protective cover 600 does not affect the relative movement of the saddle 300 in the x-axis direction, and to ensure the protective effect of the first protective cover 600. Meanwhile, since the first protective cover 600 is connected to the saddle 300, and the y-axis drive module 200 is mounted on the saddle 300, and the drive support platform 100 moves relative to the saddle 300 along the y-axis direction, the adjacent support platforms 100 are not interfered with by the first protective cover 600 when they move relative to each other in the y-axis direction. Furthermore, the second protective cover 700 can protect the y-axis drive module 200 and reduce the impact of cutting fluid on the y-axis drive module 200.

[0059] Specifically, the second protective cover 700 is a telescopic protective cover that can extend and retract along the y-axis. One end is fixed to the saddle 300, and the other end is fixed to the support platform 100. When the support platform 100 moves relative to the saddle 300 along the y-axis, the second protective cover 700 can extend and retract to limit its position in the y-axis direction and prevent it from interfering with other structures. Furthermore, each support platform 100 corresponds to two second protective covers 700, which are respectively arranged on both sides of the support platform 100 in the y-axis direction to ensure that the y-axis drive module 200 is shielded.

[0060] Reference Figure 3 and Figure 4 According to some embodiments of this application, at least one saddle 300 is formed with a sliding channel 310 extending along the x-axis direction, and a first protective cover 600 is movably disposed within the sliding channel 310.

[0061] It is understandable that the first protective cover 600 is installed in the sliding channel 310. When two adjacent saddles 300 move relative to each other in the x-axis direction, the first protective cover 600 slides in the sliding channel 310 so as to receive part of the first protective cover 600 through the sliding channel 310 and guide the movement of the first protective cover 600 through the sliding channel 310.

[0062] Specifically, the sliding channel 310 is equipped with an anti-friction pad to prevent the first protective cover 600 from directly rubbing against the inner wall of the sliding channel 310, thereby improving the service life of the first protective cover 600.

[0063] Specifically, the distance between two adjacent saddles 300 along the x-axis does not exceed the length of the first protective cover 600 along the x-axis, so as to prevent the first protective cover 600 from disengaging from the sliding channel 310.

[0064] Reference Figure 4 According to some embodiments of this application, the sliding channel 310 extends through both ends of the saddle 300.

[0065] It is understandable that the two ends of the sliding channel 310 pass through both ends of the saddle 300 in the x-axis direction, which facilitates the installation of the first protective cover 600 and allows the saddles 300 in various positions to be made with the same shape. In addition, in some cases, one end of the sliding channel 310 is used to insert the first protective cover 600, and the other end of the sliding channel 310 can be used for the first protective cover 600 to exit. For example, when the two saddles 300 are close to each other in the x-axis direction, the first protective cover 600 can exit from one end of the sliding channel 310 to avoid the sliding channel 310 interfering with the movement of the first protective cover 600.

[0066] Reference Figure 3 and Figure 5 According to some embodiments of this application, the saddle 300 includes an upper seat 320 and a lower seat 330, the upper seat 320 and the lower mold are detachably connected, and a sliding channel 310 is defined between the upper seat 320 and the lower seat 330.

[0067] Understandably, when the upper seat 320 and the lower seat 330 are detached, the sliding channel 310 opens to facilitate the installation of the first protective cover 600. When the upper seat 320 and the lower mold are connected, the sliding channel 310 is formed between the upper seat 320 and the lower seat 330 to limit the first protective cover 600. The detachable connection between the upper seat 320 and the lower seat 330 facilitates the installation of the first protective cover 600.

[0068] Reference Figure 5 According to some embodiments of this application, the upper seat 320 is provided with a through groove 321, and the lower seat 330 is provided with a protrusion 331. The protrusion 331 is inserted into the through groove 321, the lower end face of the upper seat 320 abuts against the upper end face of the lower seat 330, and a sliding channel 310 is formed between the outer side of the protrusion 331 and the groove wall of the through groove 321.

[0069] It is understandable that both the through groove 321 and the protrusion 331 extend along the x-axis. After the upper seat 320 and the lower seat 330 are connected, the protrusion 331 of the lower seat 330 is inserted into the through groove 321 of the upper mold. The outer side of the protrusion 331 is spaced apart from the groove wall of the through groove 321, and the lower end face of the upper seat 320 and the upper end face of the lower seat 330 abut against each other to form a sliding channel 310 that passes through the saddle 300 in the x-axis direction. The cross-section of the sliding channel 310 is roughly "U" shaped. Correspondingly, the cross-section of the first protective cover 600 is also roughly "U" shaped, so as to achieve a better splash prevention effect and flow guiding effect. The "U" shaped sliding channel 310, together with the "U" shaped first protective cover 600, can improve the limiting effect of the first protective cover 600.

[0070] Reference Figure 2 and Figure 6 According to some embodiments of this application, three saddles 300 are provided, and two first protective covers 600 are provided. The three saddles 300 are distributed along the x-axis direction. One end of each of the two first protective covers 600 is fixed to opposite sides of the saddles 300, and the other end is slidably inserted through the two saddles 300.

[0071] It is understood that in some embodiments, three saddles 300 are provided, and correspondingly, three support platforms 100, three y-axis drive modules 200, and three x-axis drive modules 400 are also provided, with each saddle 300, y-axis drive module 200, support platform 100, and x-axis drive module 400 corresponding one-to-one. The three saddles 300 are distributed along the x-axis direction. The two sides of the middle saddle 300 in the x-axis direction are respectively fixedly connected to one end of a first protective cover 600. The other end of the first protective cover 600 passes through the sliding channel 310 of the adjacent saddle 300, thereby fixing the first protective cover 600 on one saddle 300. During the installation process, it is only necessary to adjust the position of the other two saddles 300 relative to the middle saddle 300, which facilitates the installation of the saddles 300 and the first protective cover 600.

[0072] Reference Figure 2 According to some embodiments of this application, the x-axis drive module 400 includes an x-axis lead screw assembly 410 and a guide rail 420. Both the x-axis lead screw assembly 410 and the guide rail 420 are fixedly connected to the base 500. The x-axis lead screw assembly 410 drives and connects to the saddle 300, and the saddle 300 is slidably disposed on the guide rail 420.

[0073] It is understandable that the x-axis lead screw assembly 410 drives the saddle 300 to slide along the x-axis direction, and the guide rail 420 guides the movement of the saddle 300.

[0074] Reference Figure 2 According to some embodiments of this application, at least two x-axis lead screw assemblies 410 are distributed along the y-axis direction.

[0075] It is understood that the x-axis lead screw assembly 410 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 module of this application.

[0076] Specifically, at least two x-axis lead screw assemblies 410 have lead screws 412 arranged parallel to each other along the y-axis direction.

[0077] Specifically, at least two x-axis lead screw assemblies 410 have lead screws 412 distributed along the x-axis direction.

[0078] Reference Figure 2 and Figure 3 According to some embodiments of this application, the x-axis lead screw assembly 410 includes a motor 411, a lead screw 412, and a nut seat 413. The motor 411 drives and connects to the lead screw 412. The nut seat 413 is slidably disposed on the lead screw 412 and connected to the saddle 300. The motor 411 is disposed at the end of the base 500 and exposed outside the first protective cover 600. The lead screw 412 passes through the lower part of the first protective cover 600 or the lower part of the saddle 300.

[0079] Understandably, the motor 411 drives the lead screw 412 to rotate. The lead screw 412 is threadedly connected to the nut seat 413. The rotation of the lead screw 412 causes the nut seat 413 to move along the x-axis, and the nut seat 413 causes the saddle 300 to move along the x-axis. The motor 411 is located at one end of the base 500 along the x-axis, away from the support platform 100. Even if the motor 411 is exposed outside the first protective cover 600, cutting fluid can be prevented from falling onto the motor 411. The lead screw 412 passes under the first protective cover 600 or the saddle 300, and is shielded by the first protective cover 600 or the saddle 300 to prevent cutting fluid from falling onto the lead screw 412.

[0080] Reference Figure 2 and Figure 3 According to some embodiments of this application, the workbench module of this application also includes a third protective cover 800, which is disposed on the saddle 300 and covers the motor 411.

[0081] Understandably, the third protective cover 800 is connected to the opposite side of the saddle 300 located at both ends in the x-axis direction, for example, referring to... Figure 7 When two saddles 300 are provided, a third protective cover 800 is provided on the opposite side of the two saddles 300. The third protective cover 800 covers the motor 411 of the x-axis lead screw assembly 410, while the lead screw 412 is shielded by the first protective cover 600 between the two saddles 300. For example, refer to... Figure 6 When the saddle 300 is provided with three, one of the third protective covers 800 is located on the right side of the saddle 300 located at the right end, and the other third protective cover 800 is located on the left side of the saddle 300 located at the left end, so as to cover the motors 411 located at both ends of the base 500.

[0082] Specifically, the third protective cover 800 is a telescopic protective cover that can extend and retract along the x-axis. One end is fixed to the saddle 300 and the other end is fixed to the base 500. When the saddle 300 moves relative to the base 500 along the x-axis, the third protective cover 800 can extend and retract to limit the position of the third protective cover 800 in the y-axis direction and prevent the third protective cover 800 from interfering with other structures when moving along the x-axis.

[0083] Reference Figure 6 and Figure 7 The machine tool according to the second aspect of the present application includes a spindle 910, a z-axis drive module 920 and a worktable module according to the first aspect of the present application. The z-axis drive module 920 is connected to the spindle 910 and is used to drive the spindle 910 to move closer to or away from the support platform 100 of the worktable module.

[0084] The machine tool according to the second aspect embodiment of this application has at least the following beneficial effects: including all the beneficial effects of the worktable module of the first aspect embodiment, which will not be repeated here.

[0085] It is understandable that there are multiple spindles 910 and z-axis drive modules 920, each corresponding to a carrier platform 100. The z-axis drive module 920 is connected to the spindle 910 to drive the spindle 910 to move up and down. Each spindle 910 corresponds to one carrier platform 100, so that parts on multiple carrier platforms 100 can be processed simultaneously.

[0086] 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.
