Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and in particular to a high-pressure-bearing linear lifting module and platform. 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, it will affect the final positioning accuracy and the stability and accuracy of the movement, making it impossible to accurately complete the work task.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] 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.

[0022] Example 1: like Figure 1-5 As shown, this utility model provides a high-pressure-bearing linear lifting module, including: a linear lifting structure 1, a shaft drive structure 2, and multiple connecting rod structures 3; the linear lifting structure 1 and the shaft drive structure 2 are coaxial; multiple connecting rod structures 3 are arranged in an array around the linear lifting structure 1; each connecting rod structure 3 includes a first connecting rod part 31, a second connecting rod part 32, a mounting base 33, and a connecting bearing 34; the first end of the first connecting rod part 31 and the first end of the second connecting rod part 32 are respectively connected to the lifting end and the fixed end of the linear lifting structure 1, and the second end of the first connecting rod part 31 and the second connecting rod part 32 are connected to the lifting end and the fixed end of the linear lifting structure 1, respectively. The second ends of the two connecting rods 32 are connected to the mounting base 33 and hinged on the mounting base 33; the connecting bearing 34 is connected to the mounting base 33 and axially abuts against the shaft drive structure 2; the shaft drive structure 2 includes a moving shaft 21, which is capable of rotation; the connecting bearing 34 abuts against the side wall of the moving shaft 21, and the side wall is provided with an array of inclined grooves 211 in the axial direction, the same number as the connecting rod structure 3; the rotation angle of the moving shaft 21 and the stroke of the connecting bearing 34 are limited by the length of the inclined grooves 211.

[0023] The high-pressure linear lifting module described in this embodiment includes a linear lifting structure 1, a shaft drive structure 2, and multiple linkage structures 3. The linear lifting structure 1, the shaft drive structure 2, and the multiple linkage structures 3 cooperate with each other to achieve precise linear lifting motion.

[0024] Specifically, such as Figure 1-2 As shown, the linear lifting structure 1 and the shaft drive structure 2 are coaxially designed, which can work together on the same axis to ensure the stability and consistency of the motion.

[0025] like Figure 3 As shown, multiple linkage structures 3 are arranged in an array around the linear lifting structure 1 and are evenly distributed on the side of the linear lifting structure 1. This can effectively support the linear lifting structure 1, improve the pressure-bearing capacity of the module, and ensure the stability of the linear lifting structure 1 when it is subsequently driven to move.

[0026] In addition, such as Figure 3As shown, each linkage structure 3 includes a first linkage portion 31, a second linkage portion 32, a mounting base 33, and a connecting bearing 34. Since the first end of the first linkage portion 31 and the first end of the second linkage portion 32 are respectively connected to the lifting end and the fixed end of the linear lifting structure 1, and the second ends of both the first linkage portion 31 and the second linkage portion 32 are connected to the mounting base 33, they are hinged under the action of the mounting base 33. This arrangement allows the linkage structure 3 to effectively transmit torque, ensuring smooth lifting motion, and also providing a certain degree of flexibility during movement, ultimately improving the adaptability and stability of the module.

[0027] The connecting bearing 34 is also connected to the mounting base 33, and the connecting bearing 34 abuts against the shaft drive structure 2 in the axial direction. The shaft drive structure 2 includes a moving shaft 21, and the connecting bearing 34 abuts against the inclined groove 211 on the side wall of the moving shaft 21. When the moving shaft 21 rotates, the connecting bearing 34 slides in the inclined groove 211, and the second connecting rod 32, the mounting base 33, and the first connecting rod 31 are compressed or relaxed under the force of the connecting bearing 34, thereby realizing the rise or fall of the linear lifting structure 1. The close cooperation between the connecting bearing 34 and the shaft drive structure 2 in this embodiment enables the connecting bearing 34 to effectively transmit force, ensuring the accuracy of the subsequent movement of the linear lifting structure 1, thereby improving the pressure-bearing capacity and movement accuracy of the module.

[0028] In general, the shaft drive structure 2 and multiple linkage structures 3 in the high-pressure linear lifting module described in this embodiment can cooperate with each other to accurately, stably and efficiently realize the linear lifting motion of the linear lifting structure 1. It can bear a large weight and is suitable for high-pressure and high-precision motion control applications.

[0029] Below, we will combine Figure 1-5 The high-pressure vertical lifting module described in this embodiment will be described in detail.

[0030] As an optional implementation method, such as Figure 3 , Figure 5 As shown, the linear lifting structure 1 includes a lifting component 11, a first support plate 12, and a second support plate 13. The two ends of the lifting component 11 are fixedly connected to the first support plate 12 and the second support plate 13, respectively. The lifting component 11 includes a fixing member 111 and a lifting member 112. The fixing member 111 and the lifting member 112 are sleeved together. The first support plate 12 and the lifting member 112 are connected to form a lifting end. The second support plate 13 and the fixing member 111 are connected to form a fixed end.

[0031] Specifically, the linear lifting structure 1 is raised and lowered under the action of the shaft drive structure 2 and multiple connecting rod structures 3. The lifting assembly 11 includes a fixing member 111 and a lifting member 112, which are sleeved together. In this embodiment, the lifting assembly 11 can be a ball spline bearing or a cylindrical rolling bearing.

[0032] More specifically, such as Figure 3 As shown, the first support plate 12 is connected to the lifting member 112 to form a lifting end, and the second support plate 13 is connected to the fixing member 111 to form a fixed end. The fixed end formed by the connection of the second support plate 13 and the fixing member 111 provides a stable base for the lifting end and connects to the second connecting rod portion 32 in the linkage structure 3. The first support plate 12 connects to the first connecting rod portion 31 in the linkage structure 3. The lifting end formed by the connection of the first support plate 12 and the lifting member 112 is responsible for completing the actual lifting action, and its lifting end can be displaced based on the fixed end under the action of the linkage structure 3. The structure of the lifting assembly 11, the first support plate 12, and the second support plate 13 ensures smooth lifting action and stability of the lifting process.

[0033] As an optional implementation method, such as Figure 3-4 As shown, multiple connecting structures are provided, with multiple linkage structures 3 arranged in an array around the periphery of the linear lifting structure 1. Each linkage structure 3 includes a first linkage part 31, a second linkage part 32, a mounting base 33, and a connecting bearing 34. An example of one linkage structure 3 will be used below.

[0034] Specifically, the first link section 31 includes a first connecting seat 311, a first connecting member 312, and a first link 313. The first connecting seat 311 is fixedly connected to the first support plate 12, and the first link 313 is movably connected to the first connecting seat 311 through the first connecting member 312. The second link section 32 includes a second connecting seat 321, a second connecting member 322, and a second link 323. The second connecting seat 321 is fixedly connected to the second support plate 13, and the second link 323 is movably connected to the second connecting seat 321 through the second connecting member 322.

[0035] The first connecting seat 311 is fixedly connected to the first support plate 12, and the first connecting rod 313 is movably connected to the first connecting seat 311 via the first connecting member 312. The second connecting seat 321 is fixedly connected to the second support plate 13, and the second connecting rod 323 is movably connected to the second connecting seat 321 via the second connecting member 322. In this embodiment, the first connecting rod portion 31 is connected to the first support plate 12 and the mounting seat 33 respectively, and the second connecting rod portion 32 is connected to the second support plate 13 and the mounting seat 33 respectively, so that a triangular force-bearing area is formed between the connecting rod structure 3 and the linear lifting structure 1, enabling the linear lifting structure 1 to achieve stable lifting under the action of the connecting structure. In addition, the first connecting rod 313 and the second connecting rod 323 can change their motion angle under the action of the mounting seat 33 and the connecting bearing 34 to achieve their predetermined mechanical function and working stroke, ensuring the normal lifting of the linear lifting structure 1.

[0036] like Figure 4 As shown, the mounting base 33 includes a mounting base body 331 and a mounting bracket 332. The mounting base body 331 is used to hinge the first connecting rod portion 31 and the second connecting rod portion 32. The mounting bracket 332 is located on the side of the mounting base body 331 and is used to support the connecting bearing 34. Specifically, one end of the first connecting rod 313 and the second connecting rod 323 are both connected to the mounting base body 331, so that the first connecting rod 313 and the second connecting rod 323 are hinged. The mounting bracket 332 is fixedly connected to the mounting base body 331 and is used to support the connecting bearing 34.

[0037] Specifically, when the motion shaft 21 rotates under the action of an external rotational driving force, the connecting bearing 34 slides within the inclined slide groove 211 and is compressed or relaxed under the action of the inclined slide groove 211. When the connecting bearing 34 is compressed, the included angle between the first connecting rod 313 and the second connecting rod 323 increases under the action of the mounting base 33, thereby driving the lifting end of the linear lifting structure 1 to rise. When the connecting bearing 34 is relaxed, the included angle between the first connecting rod 313 and the second connecting rod 323 decreases under the action of the mounting base 33, thereby driving the lifting end of the linear lifting structure 1 to fall. When the linear lifting structure 1 rises and falls under the action of the connecting rod structure 3, its stability and accuracy are ensured.

[0038] As an optional implementation, the shaft drive structure 2 includes, for example: Figure 2 , Figure 5As shown, the motion shaft 21 has its side wall abutting against the connecting bearing 34, and is used to control or change the stroke of the connecting rod structure 3. Specifically, the side wall of the motion shaft 21 and the connecting bearing 34 is provided with the same number of inclined grooves 211 as the connecting rod structure 3. The inclined grooves 211 are arranged one-to-one with the connecting bearings 34 on the connecting rod structure 3. The stroke of the connecting bearing 34 in the connecting rod structure 3 is limited by the length of the inclined groove 211 and the inclination angle of the inclined groove 211.

[0039] like Figure 2 As shown, since the travel of the connecting bearing 34 in the connecting rod structure 3 is limited by the length and inclination angle of the inclined groove 211, and the inclined groove 211 is set on the side wall of the moving shaft 21, it can be seen that the rotation angle of the moving shaft 21 needs to be matched with the number of inclined grooves 211. In this embodiment, the rotation angle of the moving shaft 21 is [value missing].

[0040] In this embodiment, to ensure the stability of the linear lifting structure 1 during movement, the rotation angle of the shaft drive structure 2 needs to be limited. Specifically, the rotation angle of the shaft drive structure 2 is set to prevent the forward and reverse rotation angles from exceeding the length range of the inclined slide 211. Ultimately, limiting the rotation angle of the moving shaft 21 ensures that the connecting bearing 34 moves accurately and stably within the inclined slide 211 without exceeding its length range. Subsequently, the linear lifting structure 1 is driven to perform precise lifting movements via the mounting base 33, the first connecting rod 31, and the second connecting rod 32, ensuring the stability and reliability of the entire system.

[0041] In this embodiment, as Figure 2 As shown, the inclined slide 211 allows the connecting bearing 34 to move along the path of the inclined slide 211 when it slides within the inclined slide 211, thereby changing the included angle between the first link 313 and the second link 323 within a certain range, and thus realizing the lifting control of the lifting end in the linear lifting structure 1.

[0042] In this embodiment, the tilt angle of the inclined slide 211 can be set according to actual needs to achieve different lifting strokes and lifting speeds. By adjusting the tilt angle of the inclined slide 211, the lifting requirements in different application scenarios can be met, improving the adaptability and flexibility of the linear lifting module.

[0043] As an optional implementation method, such as Figure 1As shown, the lifting module also includes a connecting platform 4, which is fixedly mounted on the top of the linear lifting structure 1. Specifically, the connecting platform 4 can be fixed to the top of the first support plate 12 by bolts or other fastening devices. The design of the connecting platform 4 not only enhances the structural strength of the entire lifting module but also provides an interface for connecting to upper equipment or loads. Through the connecting platform 4, various equipment or loads can be easily installed, enabling precise vertical lifting. In addition, the connecting platform 4 has good load-bearing capacity and stability, ensuring the safety and reliability of the lifting module when carrying heavy objects.

[0044] In this embodiment, the material of the connecting platform 4 can be selected according to the actual situation, such as ceramic and steel. For example, if welding or other work needs to be performed on the platform using the high-pressure linear lifting module, the material of the connecting platform 4 can be ceramic, which can provide heat insulation to ensure the normal operation of the high-pressure linear lifting module.

[0045] As an optional implementation method, such as Figure 5 As shown, the shaft drive structure 2 also includes a connecting shaft 22, which is connected to the moving shaft 21 to enable the smooth rotation of the moving shaft 21. Specifically, the connecting shaft 22 includes an inner ring 221 and an outer ring 222, with a rolling element (not shown) between them. The outer ring 222 is fixed and cannot move. The inner ring 221 is fixedly connected to the moving shaft 21, and when the moving shaft 21 moves, the inner ring 221 rotates synchronously with it. The connecting shaft 22 enhances the overall stability and durability of the shaft drive structure 2 and ensures the accuracy and smoothness of the moving shaft 21 during rotation.

[0046] As an optional implementation method, such as Figure 5 As shown, the lifting module also includes a base 5, which is located below the linear lifting structure 1 and the shaft drive structure 2. Specifically, the base 5 serves as a support component for the entire lifting module, fixing the shaft drive structure 2 and the linear lifting structure 1 while also bearing the load generated by the linear lifting structure 1 during lifting. Furthermore, the base 5 is provided with a rotating placement slot 51 adapted to the shaft drive structure 2, allowing the shaft drive structure 2 to be precisely placed on the base 5 and rotated within the rotating placement slot 51, ensuring the stability of the shaft drive structure 2 during rotation. In this embodiment, the shaft drive structure 2 includes a connecting shaft 22 and a moving shaft 21. The placement of either the connecting shaft 22 or the moving shaft 21 within the rotating placement slot 51 can be selected based on actual conditions, but regardless of the placement, it will not affect the normal operation of the shaft drive structure 2.

[0047] The working principle of the high-pressure linear lifting module described in this embodiment is as follows: A rotational driving force is applied to the motion shaft 21, causing the motion shaft 21 to rotate. Since the side wall connecting the motion shaft 21 and the connecting bearing 34 is provided with a corresponding inclined groove 211, and the connecting bearing 34 is axially abutting against the inclined groove 211, the connecting bearing 34 will move along the path of the inclined groove 211 when the motion shaft 21 rotates. The connecting bearing 34 will be compressed or relaxed under the action of the inclined groove 211. At this time, the mounting seat 33 connected to the connecting bearing 34 will change the included angle between the first connecting rod 313 and the second connecting rod 323. When the connecting bearing 34 is compressed under the action of the inclined slide groove 211, the included angle between the first connecting rod 313 and the second connecting rod 323 will increase, causing the lifting end in the linear lifting structure 1 to rise linearly; when the connecting bearing 34 is relaxed under the action of the inclined slide groove 211, the included angle between the first connecting rod part 31 and the second connecting rod part 32 will decrease, causing the lifting end in the linear lifting structure 1 to descend linearly, thereby realizing the lifting of the linear lifting structure 1, which has strong stability and reliability.

[0048] In this embodiment, the diagram shows that the motion shaft 21 is disposed on the outer ring of the connecting rod structure 3, and the connecting bearing 34 abuts against the inner wall of the motion shaft 21. When the motion shaft 21 rotates, it applies a corresponding force to the connecting shaft 22, causing the lifting end of the linear lifting structure 1 to rise or fall. However, this is only the embodiment described in detail in this embodiment. Alternatively, disposing of the motion shaft 21 on the inner ring of the connecting rod structure 3, with the connecting bearing 34 abutting against the outside of the motion shaft 21, is also an implementation method of this embodiment.

[0049] The embodiment is merely a special case and does not indicate that this utility model is implemented in such a way.

[0050] Example 2: Based on the same inventive concept, Embodiment 2 of this utility model also provides a high-pressure linear lifting platform, including the high-pressure linear lifting module described in Embodiment 1, and further including a support plate and a support platform. The support platform is located at the first end of the high-pressure linear lifting module and is used to support the high-pressure linear lifting module. The support plate is located at the second end of the high-pressure linear lifting module and is used to support the product to be tested or assembled.

[0051] The high-pressure-bearing linear lifting platform described in this embodiment can be a testing platform, a welding and assembly platform, or other platforms that require the use of a high-pressure-bearing linear lifting module.

[0052] For example, if the device described in this embodiment is a testing device, the support platform is located at the first end of the high-pressure linear lifting module and is connected to the base 5 in the high-pressure linear lifting module, supporting the high-pressure linear lifting module, which can then be raised and lowered on the support platform. The support plate is located at the second end of the high-pressure linear lifting module and is connected to the connecting platform 4 in the high-pressure linear lifting module. The testing device may also include a testing component mounted above the high-pressure linear lifting module for testing. With the high-pressure linear lifting module, even if the weight of the part to be tested is relatively heavy, the part to be tested placed on the support plate can be smoothly raised and lowered in the axial direction, moving closer to or away from the testing component, facilitating better testing of the part by the testing component.

[0053] For example, the device described in this embodiment is a welding assembly device. The support platform is located at the first end of the high-pressure linear lifting module and is connected to the base 5 in the high-pressure linear lifting module, supporting the high-pressure linear lifting module, which can then be raised and lowered on the support platform. The support plate is located at the second end of the high-pressure linear lifting module and is connected to the connecting platform 4 in the high-pressure linear lifting module. The welding assembly device may also include welding assembly components (specifically, a robotic arm) mounted above the high-pressure linear lifting module for assembly. With the high-pressure linear lifting module, even if the weight of the part to be assembled is relatively heavy, the part to be tested placed on the support plate can smoothly move the part to be assembled in the axial direction, moving it closer to or away from the assembly component, facilitating better welding assembly of the part to be assembled by the assembly component.

Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present utility model. Furthermore, under the teachings of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
