Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to an axial motion module and machining equipment. Background Technology

[0002] In desktop laser processing equipment, 3D printers, and other processing equipment, the laser head, print head, and other processing heads need to be mounted on an axial motion module so that the processing head can be raised, lowered, or moved horizontally. In related technologies, the axial motion module usually uses optical axes or linear rails as guides, with sliders fitted onto the optical axes and linear rails. Typically, both the sliders and guides are made of metal, and the fit between the two is ensured by guaranteeing the structural stability of the sliders and guides. This setup results in a relatively heavy axial motion module. Utility Model Content

The second limiting part is located on the side of the second limiting part facing the first limiting part.

[0007] The first limiting part is configured as one of the limiting groove and the limiting protrusion, and the second limiting part is configured as the other of the limiting groove and the limiting protrusion, with at least a portion of the limiting protrusion embedded in the limiting groove.

[0009] In one embodiment, the axial motion module further includes an elastic element sandwiched between the two connecting arms to apply an elastic force to the two connecting arms to drive them away from each other.

[0010] In one embodiment, the cross-sectional profile of the limiting groove is arc-shaped, and the protruding surface of the limiting protrusion is set as an arc surface.

[0011] In one embodiment, the axial motion module further includes a drive assembly disposed on the slide block and connected to the slider, the drive assembly being used to drive the slider to slide.

[0012] And / or, the axial motion module includes at least two of the slide blocks, with the slide grooves on each slide block being coaxially arranged.

[0013] In one embodiment, the slider is provided with a screw hole, and the drive component of the axial motion module includes:

[0014] A drive motor, the drive motor being mounted on the slide; and

[0015] A lead screw, one end of which is connected to the output shaft of the drive motor, and the lead screw is threaded into the screw hole.

[0016] This application also proposes a processing apparatus, comprising:

[0017] A machine tool, wherein the machine tool is provided with a processing area;

[0018] The axial motion module as described in any of the foregoing embodiments, wherein the axial motion module is disposed in the processing area; and

[0019] A processing head is mounted on the slider of the axial motion module and is located above the processing area.

[0020] In one embodiment, the slide groove of the slide block extends vertically, and the slider drives the processing head to move up and down vertically.

[0021] The processing equipment also includes a translation module, which includes an optical axis and a sliding component. The optical axis extends horizontally, and the sliding component includes a connected moving block and a connector. The connector is slidably fitted onto the optical axis, and the slide block of the axial motion module is connected to the sliding component.

[0022] In one embodiment, the connector includes two elastic arms, one end of the two elastic arms is connected, and the other end is spaced apart circumferentially along the optical axis, forming a snap-fit ​​space with an opening on one side between the two elastic arms.

[0023] The central angle of the opening does not exceed 180°, and the optical axis is clamped in the snap-fit ​​space.

[0042] This utility model proposes an axial motion module 100.

[0043] Please see Figure 2 and Figure 3 In one embodiment of this utility model, the axial motion module 100 includes a slide block 10 and a slider 20. One side surface of the slide block 10 is provided with a groove 11, and the side wall of the groove 11 is provided with a first limiting part 12, which extends along the length direction of the groove 11. At least one of the slider 20 and the slide block 10 is made of plastic. The slider 20 includes a block body 21, a connecting arm 22, and a second limiting part 23. The connecting arm 22 is located on the side of the block body 21 facing the groove 11 and is inserted into the groove 11. The second limiting part 23 is located on the side of the second limiting part 23 facing the first limiting part 12. The first limiting part 12 is one of a limiting groove 121 and a limiting protrusion 231, and the second limiting part 23 is the other of the limiting groove 121 and the limiting protrusion 231. At least a portion of the limiting protrusion 231 is embedded in the limiting groove 121.

[0044] In this embodiment, the axial motion module 100 consists of a slide block 10 and a slider 20. The slide block 10 is provided with a sliding groove 11. The slider 20 includes a block body 21 for mounting the processing head 300 and a connecting arm 22 connected to the block body 21. The connecting arm 22 is inserted into the sliding groove 11 so that the slider 20 is slidably connected to the slide block 10. When the slider 20 slides along the slide block 10, the connecting arm 22 slides in the sliding groove 11 to limit the slider 20 and prevent the slider 20 from deviating from the sliding direction. One of the slide block 10 and the slider 20 can be made of plastic, and the other can be made of metal, or both the slider 20 and the slide block 10 can be made of plastic. This helps to reduce the weight of the axial sliding module. When the slider 20 is made of plastic, the motion load on the slider 20 can also be reduced, which helps to improve the stability of the drive assembly 30 driving the slider 20 to slide and provides greater traction force to the slider 20.

[0045] Meanwhile, a first limiting part 12 is provided on the side wall of the slide groove 11, and a second limiting part 23 is provided on the connecting arm 22. The first limiting part 12 can be set as a limiting groove 121, and the second limiting part 23 can be set as a limiting protrusion 231; or the first limiting part 12 can be set as a limiting protrusion 231, and the second limiting part 23 can be set as a limiting groove 121, with the limiting protrusion 231 locked in the limiting groove 121. This allows the slider 20 to engage with the slide block 10, making it difficult for the connecting arm 22 to disengage from the slide groove 11, thus improving the fit between the slider 20 and the slide block 10. With this engagement method, since the connecting arm 22 and the second limiting part 23 of the slider 20 are locked in the groove, and the slide block 10 and / or the slider 20 are made of plastic, the toughness of the plastic can neutralize the assembly tolerances and fit tolerances of the parts, which also helps to improve the fit between the slider 20 and the slide block 10, thereby improving the stability of the slider 20 during the sliding process.

[0046] Please see Figure 3 In one embodiment, the two groove sidewalls of the slide groove 11 are provided with a first limiting part 12, and the slider 20 includes two connecting arms 22 arranged side by side along the width direction of the slide groove 11, and a second limiting part 23 is provided on the side of the connecting arm 22 facing away from the other connecting arm 22.

[0047] In this embodiment, both sidewalls of the slide groove 11 are provided with a first limiting part 12, and two connecting arms 22 and two second limiting parts 23 are provided on the slider 20. Each connecting arm 22 has a second limiting part 23 on the side facing away from the other connecting arm 22. Each second limiting part 23 is engaged with the first limiting part 12 on the same side. This arrangement helps to improve the stability of the slider 20 and the slide block 10.

[0048] Please see Figure 3 In one embodiment, the axial motion module 100 further includes an elastic element 24, which is sandwiched between two connecting arms 22 to apply an elastic force to the two connecting arms 22 to drive the two connecting arms 22 away from each other.

[0049] In this embodiment, the axial motion module 100 is provided with an elastic element 24 sandwiched between the two connecting arms 22. The elastic element 24 can be, but is not limited to, a spring, an elastic airbag, or other structures. When the elastic element 24 is in an elastically compressed state, it can apply an elastic force to the two connecting arms 22, so that the connecting arms 22 are close to the sidewall of the slide groove 11, ensuring that the first limiting part 12 and the second limiting part 23 are engaged with each other. This can compensate for dimensional deviations caused by bending deformation of the connecting arms 22, machining errors of the slider 20, and machining errors of the slide groove 11, thereby improving the fit between the slider 20 and the slide groove 11.

[0050] Please see Figure 3In one embodiment, the cross-sectional profile of the limiting groove 121 is arc-shaped, and the protruding surface of the limiting protrusion 231 is set as an arc surface.

[0051] In this embodiment, the cross-sectional profile of the limiting groove 121 and the protruding surface of the limiting protrusion 231 are both set to arc shape. The protruding surface of the limiting protrusion 231 can be set to a spherical surface or a cylindrical surface. This setting can reduce the friction between the limiting protrusion 231 and the groove wall of the limiting groove 121, and also facilitate the locking of the limiting protrusion 231 into the limiting groove 121.

[0052] Please see Figure 2 and Figure 3 In one embodiment, the axial motion module 100 further includes a drive component 30, which is disposed on the slide block 10 and connected to the slider 20. The drive component 30 is used to drive the slider 20 to slide.

[0053] In this embodiment, the axial motion module 100 further includes a drive assembly 30 for driving the slider 20 to slide. The drive assembly 30 can be configured as a motor lead screw 32 assembly, with the lead screw 32 parallel to the slide groove 11 and threadedly connected to the slider 20, or threadedly connected to a nut connected to the lead screw 32 on the slider 20. The motor drives the lead screw 32 to rotate, thereby driving the slider 20 to slide relative to the slide block 10 along the axial direction of the lead screw 32. The drive assembly 30 can also be configured as a synchronous belt assembly, with both ends of the synchronous belt wound around the driving pulley and the driven pulley, respectively. The synchronous belt is connected to the slider 20 of the slider, and the motor drives the driving pulley to rotate, thereby driving the synchronous belt to move relative to the driving pulley and the driven pulley, thereby driving the sliding assembly 202 to slide along the slide block 10. The drive assembly 30 can also be configured as a cylinder or hydraulic cylinder push assembly, a gear and rack transmission assembly, a worm gear transmission assembly, a motor connecting rod transmission assembly, etc., and is not limited here.

[0054] Please see Figure 3 In one embodiment, the slider 20 is provided with a screw hole, and the drive assembly 30 of the axial motion module 100 includes a drive motor 31 and a lead screw 32. The drive motor 31 is mounted on the slide block 10; one end of the lead screw 32 is connected to the output shaft of the drive motor 31, and the lead screw 32 is threadedly connected to the screw hole.

[0055] In this embodiment, the drive assembly 30 is configured as a motor lead screw 32 assembly. The drive motor 31 is mounted on the slide 10, either directly or by mounting a mounting base 40 on the slide 10. The lead screw 32 passes through a threaded hole in the slide 10 and engages with the threaded hole. The output shaft of the drive motor 31 is connected to the lead screw 32 to drive the lead screw 32 to rotate, thereby causing the slider 20 to slide along the slide 10. Optionally, the drive motor 31 can be configured as a stepper motor or a servo motor. Using the motor lead screw 32 assembly as the drive assembly 30 provides higher transmission and positioning accuracy, allowing for better control of the sliding distance and position of the slider 20 and improving control precision.

[0056] In one embodiment, the axial motion module 100 includes at least two slides 10, with grooves 11 on each slide 10 arranged coaxially.

[0057] In this embodiment, two or more slide blocks 10 can be arranged sequentially to extend the length of the slide groove 11, thereby increasing the sliding stroke of the slide block 10; and the length of the slide groove 11 on a single slide block 10 can be reduced, making it easier to control the straightness of the slide groove 11 on a single slide block 10 and facilitating processing. Optionally, two adjacent slide blocks 10 can be connected to or abut against each other, or two adjacent slide blocks 10 can be spaced apart, which is not limited here.

[0058] Please see Figure 1 This application also proposes a processing equipment 1000, including a machine base, an axial motion module 100 and a processing head 300. The machine base is provided with a processing area. The specific structure of the axial motion module 100 refers to any of the foregoing embodiments. The axial motion module 100 is located in the processing area. The processing head 300 is mounted on the slider 20 of the axial motion module 100 and is located above the processing area.

[0059] In this embodiment, the machine base of the processing equipment 1000 serves as the supporting foundation for the processing equipment 1000 and is provided with a processing area for placing workpieces. The processing head 300 is mounted in the machine base via the axial motion module 100 and is located above the processing area. It can be used to process the workpieces in the processing area. The processing head 300 can slide along the slide block 10 with the slider 20 to adjust the position of the processing head 300. Optionally, the slide groove 11 of the slide block 10 in the axial motion module 100 can be extended horizontally to allow the slider 20 and the processing head 300 to translate horizontally; the slide groove 11 can also be extended vertically to allow the slider 20 and the processing head 300 to move up and down in the height direction.

[0060] Optionally, the processing head 300 may include a laser head for performing at least one laser processing operation such as laser cutting, laser welding, laser marking, and laser engraving; the processing head 300 may also include at least one of an inkjet print head, a 3D print head, and a tool module for performing processing operations such as inkjet printing, 3D printing, or cutting. In some embodiments, the processing head 300 may include two or more of the following processing heads 300: a laser head, an inkjet print head, a 3D print head, and a tool module, enabling various processing operations to be performed on the processing equipment 1000.

[0061] Since the processing equipment 1000 proposed in this application can adopt all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0062] Please see Figure 1 In one embodiment, the slide groove 11 of the slide block 10 extends vertically, and the slider 20 drives the processing head 300 to rise and fall vertically. The processing equipment 1000 also includes a translation module 200, which includes an optical axis 201 and a sliding component 202. The optical axis 201 extends horizontally, and the sliding component 202 includes a moving block 2021 and a connecting member 2022 connected to each other. The connecting member 2022 is slidably sleeved on the optical axis 201. The slide block 10 of the axial motion module 100 is connected to the sliding component 202.

[0063] In this embodiment, the processing head 300 can move vertically up and down with the slider 20, while the slide block 10 is mounted on the sliding component 202 of the translation module 200 and can also slide horizontally along the optical axis 201 with the sliding component 202, thereby allowing the processing head 300 to move horizontally to different positions for processing. The sliding component 202 includes a connected moving block 2021 and a connecting member 2022. The slide block 10 is connected to the moving block 2021, and the connecting member 2022 is sleeved on the optical axis 201. The connecting member 2022 can be a sleeve or a claw structure formed by two elastic arms 2023 as described in the following embodiment; no limitation is made here.

[0064] Optionally, in some embodiments, the moving block 2021 can be made of plastic. This allows the toughness of the plastic material to moderate the assembly and machining tolerances of the various parts of the translation module 200, resulting in a better fit between the sliding component 202 and the optical axis 201. This reduces the risk of uneven sliding of the sliding component 202 due to assembly and machining tolerances, and improves the stability of the sliding component 202 during its sliding process. Simultaneously, the plastic material also reduces the weight of the sliding component 202, lowering the motion load and further contributing to improved stability during its sliding process.

[0065] Please see Figure 4 and Figure 5 In one embodiment, the connector 2022 includes two elastic arms 2023, one end of which is connected and the other end is spaced apart along the circumference of the optical axis 201. A snap-fit ​​space 2025 with an opening 2026 on one side is formed between the two elastic arms 2023. The central angle of the opening 2026 does not exceed 180°, and the optical axis 201 is clamped in the snap-fit ​​space 2025.

[0066] In this embodiment, the connector 2022 includes two connected elastic arms 2023, and a snap-fit ​​space 2025 with an opening 2026 on one side is formed between the two elastic arms 2023. The central angle of the opening 2026 does not exceed 180° and can be set to any value of 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 180° or not exceeding 180°, so that the central angle of the opening 2026 does not exceed 180°, so that the claw can better clamp the optical axis 201. Meanwhile, the connector 2022 is composed of two elastic arms 2023, which allows the connector 2022 to open outward and generate elastic deformation, thereby changing the size of the snap-fit ​​space 2025 accordingly. This can accommodate manufacturing errors. For example, if the cross-sectional size of the optical axis 201 is processed to be too large or the size of the connector 2022 is processed to be too small, the connector 2022 can be stretched open and stably clamped onto the optical axis 201. This can prevent the sliding component 202 from wobbling relative to the optical axis 201, thereby improving the stability of the sliding component 202 relative to the optical axis 201.

[0067] Please see Figure 5 In one embodiment, the optical axis 201 can enter and exit the snap-fit ​​space 2025 from the opening 2026.

[0068] In this embodiment, a large opening 2026 is formed between the free ends of the two elastic arms 2023. The optical shaft 201 can enter and exit the locking space 2025 through the opening 2026. The two elastic arms 2023 can open or close relative to each other to adjust the size of the opening 2026 of the locking space 2025. For example, when the optical shaft 201 passes through the opening 2026, the two elastic arms 2023 can be opened to enlarge the opening 2026. After the optical shaft 201 enters the locking space 2025, the two elastic arms 2023 can close to each other to narrow the opening 2026, preventing the optical shaft 201 from exiting. This arrangement eliminates the need to sleeve the connector 2022 onto the optical shaft 201 from its end. The sliding component 202 can be assembled and disassembled while the optical shaft 201 is mounted on the fixed bracket, improving ease of use.

[0069] Please seeFigure 5 In one embodiment, the free end of the elastic arm 2023 is provided with a hook 2024 that bends toward the snap-fit ​​space 2025 and abuts against the optical axis 201.

[0070] In this embodiment, a hook 2024 is provided at the end of the elastic arm 2023. The hook 2024 is bent toward the snap-fit ​​space 2025, so that when the connector 2022 clamps the optical axis 201, the hook 2024 can be inwardly engaged and pressed against the optical axis 201, thereby improving the connection strength between the connector 2022 and the optical axis 201, making the sliding component 202 stably connected to the optical axis 201, and improving the stability of the sliding component 202 sliding along the optical axis 201.

[0071] In one possible embodiment, the openings 2026 of the two connectors 2022 face the same direction, or the openings 2026 of the two connectors 2022 face at an angle.

[0072] Please see Figure 5 In one embodiment, the axial motion module 100 includes two optical axes 201, and the sliding component 202 includes two connectors 2022, each connector 2022 being sleeved on one optical axis 201; the opening 2026 of one connector 2022 is oriented in the same direction as the arrangement of the two optical axes 201, and the opening 2026 of the other connector 2022 is oriented at an angle to the arrangement of the two optical axes 201.

[0073] In this embodiment, the axial motion module 100 can be provided with at least two optical axes 201. The arrangement of two optical axes 201 can better limit the sliding component 202, which can improve the stability of the sliding component 202 during the sliding process and prevent the sliding component 202 from rotating around the optical axes 201. The openings 2026 of the two connectors 2022 of the sliding component 202 are oriented in different directions. The opening 2026 of one of them is oriented in the same direction as the arrangement of the two optical axes 201. In this case, the opening 2026 of the connector 2022 can be oriented towards or away from the other connector 2022. The opening 2026 of the other connector 2022 is oriented at an angle to the arrangement of the two optical axes 201.

[0074] Specifically, the motion block 2021 has a mounting surface for mounting the laser head. Taking two optical axes 201 arranged vertically along the height direction and two connectors 2022 both located on the side of the motion block 2021 facing away from the mounting surface as an example, the opening 2026 of the upper connector 2022 can be positioned facing away from the motion block 2021, and the opening 2026 of the lower connector 2022 can be positioned facing away from the upper connector 2022; alternatively, the opening 2026 of the upper connector 2022 can be positioned facing towards the lower connector 2022, and the opening 2026 of the lower connector 2022 can be positioned facing away from the motion block 2021. In this configuration, the sliding component 202 can be limited in different directions by two connectors 2022 to the optical axis 201. For example, when only a force perpendicular to the mounting surface is applied, the connector 2022 with the opening 2026 facing the same direction as the two optical axes 201 will not detach from the optical axis 201. When an upward or downward force is applied, the connector 2022 with the opening 2026 facing the direction intersecting the two optical axes 201 will not detach from the optical axis 201. This helps to improve the stability of the sliding component 202 mounted on the optical axis 201 and reduces the risk of the sliding component 202 detaching from the optical axis 201 and falling off.
