[0037] 401. Install the end plate. Detailed Implementation
[0038] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0039] like Figures 1-3As shown, this embodiment discloses a planar floating uprighting mechanism, which mainly includes components such as a fixed plate 1, a floating plate 2, a connecting rod, and a plug pipe 9. The careful design of these components makes the entire mechanism both stable and flexible, and can efficiently complete the measurement task.
[0040] Specifically, each component will be described in detail with reference to the accompanying drawings:
[0041] In this embodiment, the fixed plate 1 serves as the supporting foundation for the entire mechanism, ensuring its stability during the measurement process. It is fixedly installed on the measuring equipment, providing a stable support platform for the entire floating measuring mechanism.
[0042] In this embodiment, the floating plate 2 is a key component for holding the probe. It can float relative to the fixed plate 1 when subjected to force, thereby adapting to the measurement requirements of different hole diameters and positions. The design of the floating plate 2 fully considers the installation and positioning of the probe, ensuring that the probe can be accurately and stably held on the floating plate. At the same time, the floating plate 2 also has a certain degree of elasticity, which can produce slight deformation when subjected to force, thereby further improving the accuracy of the measurement.
[0043] In this embodiment, the connecting rod 3 is a crucial component connecting the fixed plate 1 and the floating plate 2. It is responsible for transmitting the buoyancy force, enabling the floating plate to float accordingly when subjected to force. The connecting rod 3 is made of lightweight, high-strength material to ensure sufficient rigidity and stability when transmitting the buoyancy force. The design of the connecting rod 3 also considers the compactness and lightweight nature of the mechanism to reduce the overall size and weight. Furthermore, the surface of the connecting rod 3 is treated with anti-corrosion coating to improve its service life.
[0044] One end of the connecting rod 3 is tightly connected to the bottom of the fixed plate 1 via a second disc spring 7 and a locking nut 8. This connection method not only ensures a stable connection between the connecting rod and the fixed plate, but also provides additional buoyancy force through the second disc spring 7, allowing the floating plate to float more smoothly under load. Meanwhile, the anti-loosening design of the locking nut 8 ensures the stability of the connection during long-term use. The connection between the connecting rod 3 and the fixed plate 1 is also designed with positioning structures such as positioning pins or positioning holes to ensure accurate positioning and stability of the connecting rod during installation. Furthermore, the end of the connecting rod 3 is chamfered or rounded to reduce friction and wear between it and the fixed plate 1.
[0045] The other end of connecting rod 3 passes through the first planar bearing 4 and connects to the floating plate 2. This connection method enables flexible connection between the connecting rod and the floating plate, allowing the floating plate to float freely within a certain range under load through the gap between the connecting rod and the planar bearing. Simultaneously, the low-friction design of the first planar bearing 4 ensures smoothness during the floating process. A shock-absorbing structure, such as a buffer pad or vibration damping pad, is also designed at the connection between connecting rod 3 and the floating plate 2 to reduce impact and vibration during the floating process. Furthermore, the clearance between connecting rod 3 and the first planar bearing 4 can be adjusted according to actual conditions to meet the floating range and accuracy requirements under different measurement needs.
[0046] This embodiment also includes a bearing assembly, which includes at least two planar bearings. The two planar bearings are respectively disposed at the upper and lower ends of the floating plate 2 and sleeved on the connecting rod 3 to achieve precise mechanical transmission. In this embodiment, the bearing assembly includes two planar bearings, namely a first planar bearing and a second planar bearing.
[0047] In this embodiment, the first planar bearing 4 is installed between the connecting rod 3 and the floating plate 2. It can achieve free rotation and minute displacement within the plane, thereby ensuring that the floating plate can float smoothly under force. The first planar bearing 4 is made of high-precision, low-friction material to ensure the smooth floating of the mechanism and the accuracy of measurement. The selection and design of the first planar bearing 4 fully consider the load capacity and service life of the mechanism to ensure stable performance during long-term use. At the same time, the first planar bearing 4 also has a certain self-lubricating property, which can reduce friction and wear of the mechanism during the floating process.
[0048] The lower end of the first planar bearing 4 is press-fitted with the floating plate 2, while the upper end is clearance-fitted with the connecting rod 3. This fit ensures a tight connection and flexible rotation between the planar bearing, the floating plate, and the connecting rod. Simultaneously, the press-fit design improves the stability and durability of the connection. The mating surfaces between the first planar bearing 4, the floating plate 2, and the connecting rod 3 are precision-machined and lubricated to reduce friction and wear, improving the smoothness of the mechanism's floating and its service life. Furthermore, the first planar bearing 4 can be selected from different types of bearings, such as ball bearings and roller bearings, to meet the load capacity and rotational accuracy requirements under different measurement needs.
[0049] In this embodiment, the second planar bearing 5 is installed between the floating plate 2 and the fixed plate 1. It also enables free rotation and minute displacement within the plane, further ensuring the smooth floating of the floating plate. The second planar bearing 5 cooperates with the first planar bearing 4 to form the floating system of the mechanism. The design of the second planar bearing 5 considers the stability and durability of the mechanism to ensure good performance even in harsh measurement environments. Simultaneously, the second planar bearing 5 also has certain dustproof and waterproof properties to protect the internal components of the mechanism from external environmental interference.
[0050] The upper end of the second planar bearing 5 is press-fitted to the floating plate 2, and the lower end is tightly fitted to the fixed plate 1 via the first disc spring 6. This connection method not only ensures a stable connection between the planar bearing and the floating and fixed plates, but also provides preload through the first disc spring 6, allowing the floating plate to remain coaxial with the fixed plate when no force is applied. Simultaneously, the low-friction design of the second planar bearing 5 ensures smoothness during the floating process. The mating surfaces between the second planar bearing 5 and the floating plate 2 and fixed plate 1 are also precision-machined and lubricated to improve the smoothness of the mechanism's floating and its service life. Furthermore, the preload of the first disc spring 6 can be adjusted according to actual measurement needs to adapt to the measurement requirements of different hole diameters and positions.
[0051] The floating plate 2 is clamped between the first planar bearing 4 and the second planar bearing 5, forming a floating structure. This structural design ensures that the floating plate can float freely within a certain range through the gaps in the planar bearings when under force, adapting to the shape and position of the hole. Simultaneously, the cooperation between the two planar bearings also improves the stability and durability of the mechanism. The clamping force between the floating plate 2 and the planar bearings can be adjusted by changing the preload of the first disc spring 6. Furthermore, the floating plate 2 can be designed with different shapes and sizes according to actual needs to meet the clamping and floating requirements under different measurement requirements.
[0052] This embodiment also includes disc spring assemblies, of which there are at least two, namely a first disc spring 6 and a second disc spring 7. The two disc springs are respectively disposed at the upper and lower ends of the fixed plate 1 and sleeved on the outside of the connecting rod 3 to provide a certain elastic force and achieve a floating effect.
[0053] In this embodiment, the first disc spring 6 is positioned between the floating plate 2 and the fixed plate 1. It provides preload, ensuring that the floating plate remains coaxial with the fixed plate when no force is applied, thereby ensuring the accuracy and repeatability of the measurement. The preload of the first disc spring 6 can be adjusted according to actual measurement needs to adapt to the measurement requirements of different hole diameters and positions. Simultaneously, the first disc spring 6 also has a certain damping and buffering effect, reducing vibration and impact on the mechanism during the measurement process.
[0054] In this embodiment, the second disc spring 7 is sleeved on the connecting rod 3 and positioned between the locking nut 8 and the fixing plate 1. It assists in providing the floating force and ensures the reset after floating. The second disc spring 7 cooperates with the first disc spring 6 to jointly constitute the floating force and reset of the mechanism. The design of the second disc spring 7 takes into account the floating range and reset speed of the mechanism to ensure that the floating and reset actions can be completed quickly and accurately during the measurement process. At the same time, the second disc spring 7 also has a certain degree of fatigue resistance, which can maintain stable performance during long-term use.
[0055] In this embodiment, the locking nut 8 is used to lock the connection between the connecting rod 3 and the fixed plate 1, ensuring the overall stability of the mechanism. The locking nut 8 is made of high-strength material and undergoes special anti-loosening treatment to ensure that it will not loosen or fall off during the measurement process.
[0056] In this embodiment, the insertion tube 9 is sleeved on the outside of the connecting rod 3, indirectly contacting the floating plate 2. A gap is reserved between the insertion tube 9 and the floating plate 2. The lower end of the insertion tube 9 is inserted into a pre-set slot on the fixed plate 1, thus guiding the floating plate 2 and allowing it to connect the probe and the floating plate 2, transmitting the measuring force. The design of the insertion tube 9 considers the versatility and adaptability of the mechanism to accommodate probes of different models and specifications. Simultaneously, the insertion tube 9 also has certain dustproof and waterproof properties to protect the probe and internal parts of the mechanism from external environmental interference.
[0057] Since the insertion tube 9 is sleeved on the outside of the connecting rod 3, the corresponding bearing assembly is sleeved on the insertion tube 9 to realize transmission.
[0058] In this embodiment, the mounting end plate 401 serves as a support for the planar bearing, ensuring its stable operation. The mounting end plate 401 is made of high-strength, high-rigidity material to ensure it can withstand significant loads and vibrations during measurement. Simultaneously, the mounting end plate 401 also possesses dustproof and waterproof properties to protect the planar bearing and internal components from external environmental interference. Furthermore, the mounting end plate 401 can be customized to meet the installation requirements of planar bearings of different models and specifications.
[0059] Mounting end plate 401 is mounted on floating plate 2 to support and position the corresponding bearing assembly. This design ensures stable operation and precise positioning of the planar bearing. At the same time, the high-strength design of mounting end plate 401 also improves the overall stability and reliability of the mounting end plate 401.
[0060] Specifically, the mounting end plate 401 includes two sets, each set including two plates. The two mounting end plates 401 in the same set are respectively set at the upper and lower ends of the corresponding plane bearing. The mounting end plate 401 on the side closer to the floating plate 2 is engaged in the groove opened on the floating plate 2, while the mounting end plate 401 on the other side is positioned by the connecting rod 3. In this embodiment, the connecting rod 3 is a T-shaped structure, which can press the mounting end plate 401 to achieve installation and fixation.
[0061] The design of the mounting end plate 401 specifically considers the positioning and guiding of the thrust bearing. Through precise calculations and dimensional matching with the thrust bearing, the mounting end plate 401 ensures that the thrust bearing can float along a predetermined trajectory under load without skewing or jamming. This design not only improves measurement accuracy but also extends the service life of the thrust bearing. To further improve the positioning accuracy and stability of the thrust bearing, the mounting end plate 401 can also be equipped with structures such as locating pins, locating holes, or guide grooves to achieve precise positioning and guiding of the thrust bearing. The design of these structures considers not only positioning accuracy but also ease of installation and maintainability.
[0062] Through the careful design and combination of the above components, the floating measurement mechanism of this utility model not only has the advantages of simple structure, small size, easy installation and debugging, but also has significant features such as smooth floating, accurate measurement and good repeatability, and is widely applicable to various automated measurement scenarios.

Its working principle is primarily based on the floating characteristics of the floating plate 2 and the synergistic effect of components such as the plane bearing and disc spring. When a measuring force is applied to the floating plate 2, it can float freely within a certain range through the gap in the plane bearing, adapting to the shape and position of the measured hole. Simultaneously, the preload and floating force provided by the disc spring ensure that the floating plate can quickly return to its original position after being subjected to force, maintaining coaxiality with the fixed plate 1, thereby ensuring the accuracy and repeatability of the measurement.

Therefore, the floating measuring mechanism can maintain stable performance and accurate measurement results throughout its entire service life.
[0069] Easy maintenance: Due to the simple, compact structure of the floating measuring mechanism, and its ease of disassembly and assembly, maintenance or component replacement is very convenient and quick. This greatly reduces maintenance and time costs and improves measurement efficiency.
