Description

Technical Field

[0001] This utility model relates to the field of motion module technology, and in particular to a high-pressure-bearing motion module and device. Background Technology

[0002] A linear module (also known as a linear slide or electric cylinder) is a modular mechanical component that integrates guide rails, transmission mechanisms (such as ball screws or synchronous belts), and drive devices (such as motors) to convert rotary motion into linear motion, enabling precise positioning and movement of loads. For example, on an automated production line, a linear module can precisely move a product from one position to another.

[0003] Specifically, linear modules move based on integrated guide rails, transmission components, and drive devices. These components have certain limitations, resulting in a limited load-bearing capacity for the linear module. If the load is heavy, the force on the linear module will be uneven and unconcentrated, affecting the module and ultimately causing it to tilt. Once tilted, the final positioning accuracy and the stability and accuracy of the movement of the load will be affected, ultimately preventing the module from accurately completing its work task.

[0004] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0005] Existing linear modules exhibit poor stability and accuracy when bearing heavy loads. Utility Model Content

[0039] To illustrate the technical solution described in this utility model, specific embodiments are described below, showing only the parts related to the embodiments of this utility model.

[0040] Example 1:

[0041] like Figure 1-7 As shown, this utility model provides a high-pressure-bearing motion module, including: a first shaft 1, a second shaft 2, and a third shaft 3; the first shaft 1 is located inside the second shaft 2, and the second shaft 2 is located inside the third shaft 3; wherein, the first shaft 1, the second shaft 2, and the third shaft 3 are coaxial; the outer ring of the first shaft 1 and the inner ring of the second shaft 2 are matched with a plurality of vertical grooves 5, and the outer ring of the second shaft 2 and the inner ring of the third shaft 3 are matched with a spiral groove 6; or, the outer ring of the first shaft 1 and the inner ring of the second shaft 2 are matched with a spiral groove 6, and the outer ring of the second shaft 2 and the inner ring of the third shaft 3 are matched with a plurality of vertical grooves 5; wherein, rolling components 4 are provided in both the vertical grooves 5 and the spiral grooves 6.

[0042] In this embodiment, as Figure 1-3 As shown, the first shaft 1 is located inside the second shaft 2, and the second shaft 2 is located inside the first shaft 1.

[0043] In some implementations, such as Figure 2As shown, the outer ring of the first shaft 1 has multiple evenly distributed first vertical grooves 51 in the axial direction, and the inner ring of the second shaft 2 has multiple evenly distributed second vertical grooves 52 in the axial direction. The first vertical grooves 51 on the outer ring of the first shaft 1 and the second vertical grooves 52 on the inner ring of the second shaft 2 are correspondingly arranged, so that the outer ring of the first shaft 1 and the inner ring of the second shaft 2 form multiple vertical grooves 5.

[0044] In addition, such as Figure 2 As shown, a first spiral groove 61 is provided on the outer ring of the second shaft 2, and a second spiral groove 62 is provided on the inner ring of the third shaft 3. The first spiral groove 61 on the outer ring of the second shaft 2 and the second spiral groove 62 on the inner ring of the third shaft 3 are correspondingly arranged, so that the outer ring of the second shaft 2 and the inner ring of the second shaft 2 form a spiral groove 6.

[0045] In other implementations, such as Figure 6 As shown, a first spiral groove 61 is provided on the outer ring of the first shaft 1, and a second spiral groove 62 is provided on the inner ring of the second shaft 2. The first spiral groove 61 on the outer ring of the first shaft 1 and the second spiral groove 62 on the inner ring of the second shaft 2 are correspondingly arranged, so that the outer ring of the first shaft 1 and the inner ring of the second shaft 2 form a spiral groove 6.

[0046] In addition, the outer ring of the second shaft body 2 is provided with multiple evenly distributed first vertical grooves 51 in the axial direction, and the inner ring of the third shaft body 3 is provided with multiple evenly distributed second vertical grooves 52 in the axial direction. The first vertical grooves 51 of the outer ring of the second shaft body 2 and the second vertical grooves 52 of the inner ring of the third shaft body 3 are correspondingly arranged, so that the outer ring of the second shaft body 2 and the inner ring of the third shaft body 3 form multiple vertical grooves 5.

[0047] In this embodiment, the pitch of the first spiral groove 61 and the pitch of the second spiral groove 62 are the same, and no specific limitation is made in this embodiment.

[0048] Regardless of which of the above implementation methods is used, such as Figure 2 , Figure 6 As shown, both the vertical groove 5 and the spiral groove 6 are equipped with rolling components 4. Specifically, the rolling components 4 are balls or rollers. The balls and rollers are used to make the first shaft 1 and the second shaft 2 cooperate, and the second shaft 2 and the third shaft 3 cooperate, so that the second shaft 2 can move in the axial direction under the action of the external driving component.

[0049] More specifically, each of the second shafts 2 can move in the axial direction, rising or falling, under the action of the first shaft 1, the third shaft 3, and the external drive component. The realization of its axial movement depends on whether the external drive component is connected to the first shaft 1 or the third shaft 3.

[0050] In this embodiment, as Figure 2 , Figure 3 , Figure 5 , Figure 6 The motion module also includes a drive connector 7, which connects to an external drive component. When the outer ring of the first shaft 1 matches the inner ring of the second shaft 2 and is provided with multiple vertical grooves 5, and the outer ring of the second shaft 2 matches the inner ring of the third shaft 3 and is provided with a spiral groove 6, it connects the third shaft 3 to the external drive component. Under the action of the external drive component, the drive connector 7 drives the third shaft 3 to rotate, and the third shaft 3, in conjunction with the first shaft 1, drives the second shaft 2 to move in the axial direction. When the outer ring of the first shaft 1 matches the inner ring of the second shaft 2 and is provided with a spiral groove 6, and the outer ring of the second shaft 2 matches the inner ring of the third shaft 3 and is provided with multiple vertical grooves 5, it connects the first shaft 1 to the external drive component. Under the action of the external drive component, the drive connector 7 drives the first shaft 1 to rotate, and the first shaft 1, in conjunction with the third shaft 3, drives the second shaft 2 to move in the axial direction.

[0051] Specifically, the first end of the drive connector 7 is connected to the external drive component, and the second end is connected to the motion module. The motion module moves in the axial direction with the external drive component through the drive connector 7.

[0052] In some embodiments, such as Figure 2 , Figure 3 As shown, when the outer ring of the first shaft 1 and the inner ring of the second shaft 2 are matched with multiple vertical grooves 5, and the outer ring of the second shaft 2 and the inner ring of the third shaft 3 are matched with a spiral groove 6, the drive connector 7 can be fixedly disposed in the circumferential direction of the third shaft 3 or disposed on the outside of the third shaft 3. However, regardless of how the drive connector 7 is disposed, the external drive assembly will drive the third shaft 3 to rotate through the drive connector 7. Due to the spiral groove 6 between the inner ring of the third shaft 3 and the outer ring of the second shaft 2, the vertical grooves 5 between the inner ring of the second shaft 2 and the outer ring of the first shaft 1, and the ball bearings disposed in the spiral groove 6 and the vertical groove 5, when the third shaft 3 rotates under the action of the external drive assembly, the second shaft 2 moves spirally in the axial direction. It should be noted that in this embodiment, the drive connector 7 is preferably fixedly disposed in the axial direction of the third shaft 3.

[0053] In other embodiments, such as Figure 5 , Figure 6 As shown, when the outer ring of the second shaft 2 and the inner ring of the third shaft 3 are matched with multiple vertical grooves 5, and the outer ring of the first shaft 1 and the inner ring of the second shaft 2 are matched with spiral grooves 6, the drive connector 7 can be fixedly arranged in the circumferential direction of the first shaft 1, or arranged on the inner side of the first shaft 1. If the drive connector 7 is arranged on the inner side of the first shaft 1, the first shaft 1 needs to be a hollow shaft.

[0054] However, regardless of the configuration of the drive connector 7, the external drive assembly will drive the first shaft 1 to rotate via the drive connector 7. Due to the helical groove 6 between the inner ring of the second shaft 2 and the outer ring of the first shaft 1, the vertical groove 5 between the inner ring of the third shaft 3 and the outer ring of the second shaft 2, and the ball bearings disposed within the helical groove 6 and the vertical groove 5, the rotation of the first shaft 1 under the action of the external drive assembly causes the second shaft 2 to move helically in the axial direction. It should be noted that in this embodiment, the drive connector 7 is preferably fixedly disposed in the axial direction of the first shaft 1.

[0055] Specifically, whether the second shaft 2 rises or falls in the axial direction depends on the driving direction of the external drive component.

[0056] In this embodiment, as Figure 1-7 As shown, the motion module also includes a placement connecting platform 8, which is arranged in the circumferential direction of the second shaft 2. Specifically, the placement connecting platform 8 is used to connect the motion module to the placement platform of other devices.

[0057] For example, in a testing device, a motion module is positioned at the bottom of a placement platform and connected to the platform within the testing device. The motion module can then move the placement platform to a specified height based on the actual testing requirements, allowing for the testing of parts placed on the platform. Similarly, in an assembly device, a motion module is positioned at the bottom of a placement platform and connected to it. The motion module can then move the placement platform to a specified height based on the actual assembly requirements, allowing for the assembly of parts placed on the platform.

[0058] In this embodiment, it is explained that the shape of the connecting platform 8 can be chosen in various ways. For example... Figure 1 , Figure 5 As shown, the shape of the connecting platform 8 can be circular, pentagonal, hexagonal, or other shapes. Circular, pentagonal, and hexagonal shapes have the characteristic of dispersing pressure. Selecting this type of shape for the connecting platform 8 allows it to better withstand and disperse pressure, ensuring stability during subsequent use.

[0059] It should be noted that, as Figure 3, Figure 5 As shown, in this embodiment, the drive connector 7 and the placement connecting platform 8 are located at opposite ends. Specifically, the first shaft 1, the second shaft 2, and the third shaft 3 each include a first end and a second end, with the first end being the bottom end and the second end being the top end. When the outer ring of the first shaft 1 matches the inner ring of the second shaft 2 with multiple vertical grooves 5, and the outer ring of the second shaft 2 matches the inner ring of the third shaft 3 with a spiral groove 6, the drive connector 7 is located at the first end of the third shaft 3, and the placement connecting platform 8 is located at the second end of the second shaft 2. Similarly, when the outer ring of the first shaft 1 matches the inner ring of the second shaft 2 with a spiral groove 6, and the outer ring of the second shaft 2 matches the inner ring of the third shaft 3 with multiple vertical grooves 5, the drive connector 7 is located at the first end of the first shaft 1, and the placement connecting platform 8 is located at the second end of the second shaft 2.

[0060] As an optional implementation, the radial width of the placement connecting platform 8 is greater than the radial width of the second shaft 2. Since the placement connecting platform 8 is a component used to connect the motion module and the external placement platform, in order to ensure that the placement connecting platform 8 stably drives the external placement platform to move, it is necessary to make the radial width of the placement connecting platform 8 greater than the radial width of the second shaft 2 to ensure the stability of the external placement platform's displacement movement in the axial direction.

[0061] In this embodiment, as Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the motion module also includes a fixed platform 9, the first end of which is fixedly connected to an external bearing component. When the outer ring of the first shaft 1 and the inner ring of the second shaft 2 are matched with multiple vertical grooves 5, and the outer ring of the second shaft 2 and the inner ring of the third shaft 3 are matched with spiral grooves 6, the second end of the fixed platform 9 is connected to the first shaft 1 to connect the first shaft 1 to the external bearing component. When the outer ring of the first shaft 1 and the inner ring of the second shaft 2 are matched with spiral grooves 6, and the outer ring of the second shaft 2 and the inner ring of the third shaft 3 are matched with multiple vertical grooves 5, the second end of the fixed platform 9 is connected to the third shaft 3 to connect the third shaft 3 to the external bearing component.

[0062] Specifically, the fixed platform 9 is used to connect the motion module to the external support component.

[0063] In some embodiments, such as Figure 2 , Figure 3As shown, when the outer ring of the first shaft 1 and the inner ring of the second shaft 2 are matched with multiple vertical grooves 5, and the outer ring of the second shaft 2 and the inner ring of the third shaft 3 are matched with spiral grooves 6, the fixed platform 9 connects the first shaft 1 to the external bearing component to prevent the first shaft 1 from moving synchronously with the second shaft 2 when the second shaft 2 moves, thereby affecting the accuracy and stability of the movement of the second shaft 2.

[0064] In other embodiments, such as Figure 5 , Figure 6 As shown, when the outer ring of the first shaft 1 and the inner ring of the second shaft 2 are matched with a spiral groove 6, and the outer ring of the second shaft 2 and the inner ring of the third shaft 3 are matched with multiple vertical grooves 5, the fixed platform 9 connects the third shaft 3 to the external bearing component to prevent the third shaft 3 from moving synchronously with the second shaft 2 when the second shaft 2 moves, thereby affecting the accuracy and stability of the movement of the second shaft 2.

[0065] It should be noted that in this embodiment, the fixed platform 9 and the drive connector 7 are located at the same end, and at opposite ends to the placement connector 8. The fixed platform 9 is used to fix the motion module and the external device, but while fixing it to the external device, it should not affect the movement of the placement connector 8 located at the second end of the second shaft 2. Therefore, the position of the fixed platform 9 is limited to ensure the normal operation of the motion module.

[0066] As an optional implementation, the axial dimensions of the first shaft 1, the second shaft 2, and the third shaft 3 are matched. Specifically, in this embodiment, the second shaft 2 can move in the axial direction under the action of the first shaft 1, the second shaft 2, the rolling assembly 4 disposed between the first shaft 1 and the second shaft 2, and the rolling assembly 4 disposed between the second shaft 2 and the third shaft 3. In order to ensure the stability of the second shaft 2 in the axial direction, the axial dimensions of the first shaft 1, the second shaft 2, and the third shaft 3 can be limited to make their axial dimensions match.

[0067] Matching axial dimensions can mean having the same axial dimensions, or it can mean that the first shaft 1, the second shaft 2, and the third shaft are distributed in proportion. In this embodiment, it is preferable that the axial dimensions are the same.

[0068] In this embodiment, since only the outer ring of the first shaft 1 needs to mate with the inner ring of the second shaft 2, no other limitations are imposed on the first shaft 1. The first shaft 1 can be either a hollow shaft or a solid shaft, neither of which will affect the axial movement of the second shaft 2.

[0069] The motion module described in this embodiment includes a first shaft 1, a second shaft 2, and a third shaft 3. The first shaft 1 is disposed within the second shaft 2, and a vertical groove 5 or a spiral groove 6 is provided between the first shaft 1 and the second shaft 2. The second shaft 2 is disposed within the third shaft 3, and a spiral or vertical groove 5 is provided between the second shaft 2 and the third shaft 3. Rolling components 4 are disposed within both the vertical groove 5 and the spiral groove 6. The second shaft 2 can stably move in the axial direction under the action of the rolling components 4 within the first shaft 1, the second shaft 2, the vertical groove 5, and the spiral groove 6. When the second shaft 2 is subjected to significant pressure, the presence of the first shaft 1 and the third shaft 3 helps to disperse the pressure, making the force distributed more evenly on the second shaft 2. Therefore, when the second shaft 2 moves, it can ensure the accuracy and stability of the movement, reduce deviations or instabilities caused by uneven force, and ensure the normal operation of the motion module.

[0070] The embodiment is merely a special case and does not indicate that this utility model is implemented in such a way.

[0071] Example 2:

[0072] An apparatus with a high-pressure-bearing motion module includes the high-pressure-bearing motion module as described in Embodiment 1, as well as a support component and a placement platform. The support component is connected to a first end of the high-pressure-bearing motion module and is used to support the high-pressure-bearing motion module. The placement platform is connected to a second end of the high-pressure-bearing motion module and is used to support a product to be tested or assembled.

[0073] The device with a high-pressure-bearing motion module described in this embodiment can be a testing device, an assembly device, or other devices that require the use of a high-pressure-bearing motion module.

[0074] For example, the device described in this embodiment is a detection device. The supporting component is located at the first end of the high-pressure-bearing motion module and is connected to the fixed platform in the high-pressure-bearing motion module, supporting the high-pressure-bearing motion module, which can move on the supporting component. The placement platform is located at the second end of the high-pressure-bearing motion module and is connected to the placement connecting platform in the high-pressure-bearing motion module. The detection device may also include a detection component mounted above the high-pressure-bearing motion module for detection. With the high-pressure-bearing motion module, even if the weight of the part to be tested is heavy, the part to be tested placed on the placement platform can smoothly move in the axial direction, moving closer to or away from the detection component, facilitating better detection of the part to be tested by the detection component.

[0075] For example, the device described in this embodiment is an assembly device. The supporting component is located at the first end of the high-pressure-bearing motion module and is connected to the fixed platform in the high-pressure-bearing motion module, supporting the high-pressure-bearing motion module, which can move on the supporting component. The placement platform is located at the second end of the high-pressure-bearing motion module and is connected to the placement connecting platform in the high-pressure-bearing motion module. The assembly device may also include an assembly component (specifically, a robotic arm) mounted above the high-pressure-bearing motion module for assembly. With the high-pressure-bearing motion module, even if the weight of the part to be assembled is heavy, the part to be tested placed on the placement platform can smoothly move the part to be assembled in the axial direction, moving it closer to or away from the assembly component, facilitating better assembly of the part to be assembled by the assembly component.
