Description

Technical Field

[0001] This invention relates to the field of mechanical equipment support technology, specifically to a floating pad mechanism with closed-loop adjustment. Background Technology

[0002] With the development and progress of the industrial sector, the number of large-scale equipment used is gradually increasing, and the foundation support at the bottom of the equipment is becoming more important. Usually, shims are used to support the middle position of the bottom of the equipment, and the shims are used to unload the middle position of the bottom of the equipment.

[0003] However, due to the need for mechanization, many large pieces of equipment have significantly larger bottom dimensions, meaning the length and width of the bottom support surface far exceed those of typical machinery. This makes it impossible to precisely adjust and unload the equipment using standard shims, leading to instability in the support at the center of the large equipment. Consequently, the base of the equipment deforms under stress, reducing the overall rigidity of the equipment. When the base of the equipment deforms under stress, it can easily affect the machining accuracy of the internal components, thus impacting the overall precision. In applications with extremely high precision requirements, such as chip processing or battery cell bonding, this directly affects the quality of the finished product. Summary of the Invention

[0004] The purpose of this invention is to provide a floating pad mechanism that can be adjusted in a closed loop.

[0005] The technical problem solved by this invention is to address the issue that the bottom dimensions of mechanical equipment are large in the prior art, and ordinary shims cannot accurately unload them.

[0006] The present invention can be achieved through the following technical solution: a closed-loop adjustable floating pad mechanism, including a spherical washer for supporting mechanical equipment, the height of the spherical washer being adjustable, and the pressure between the spherical washer and the mechanical equipment being obtained through a sensing device, the pressure between the spherical washer and the mechanical equipment being used as a parameter for controlling the height of the spherical washer.

[0007] A further technical improvement of the present invention is that: the spherical washer is installed on the top sleeve, and a pressure sensor for sensing the pressure on it is provided between the spherical washer and the top sleeve; the spherical washer is slidably mounted on the pad seat, and the pad seat and the mechanical equipment are positioned and matched.

[0008] A further technical improvement of the present invention is that the top sleeve is fixedly installed on the power end of the oil cylinder, and the oil flow rate of the oil cylinder is controlled by the pressure reducing valve through the hydraulic station and accumulator.

[0009] A further technical improvement of the present invention is that: the spherical washer is mounted on the support protrusion, the support protrusion is mounted on the side support plate, and the height of the side support plate is adjustable.

[0010] A further technical improvement of the present invention is that: the side support plate is fixed on the connecting rod, the connecting rod and the connecting support are fixedly connected, and an inclined slider is fixed at the end of the connecting support away from the connecting rod. The inclined slider and the inclined slide rod are slidably connected, and the inclined slider is pushed by the pushing mechanism.

[0011] A further technical improvement of the present invention is that: the pushing mechanism includes a hydraulic cylinder, the power end of the hydraulic cylinder is fixed with a hinge base, a hinge connecting rod is hinged on the hinge base, and the end of the hinge connecting rod away from the hinge base is hinged to a connecting support.

[0012] A further technical improvement of the present invention is that an intermediate support plate is slidably installed between adjacent side support plates, the intermediate support plate is slidably connected to the frame, and a support protrusion is provided on the intermediate support plate.

[0013] A further technical improvement of the present invention is that a side slide rod is fixed on the side of the middle support plate, and a side slider is fixed on the side of the side slide rod away from the middle support plate, and the side slider slides inside the side support plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This application uses several sets of spherical washers to support the bottom of the mechanical equipment, thereby achieving the unloading effect of the mechanical equipment. When the middle position of the mechanical equipment deforms due to gravity, the pressure sensor detects the force borne by the spherical washers and feeds the force back to the control system. The control system controls the height of the spherical washers, causing them to deform slightly upwards, thus supporting the mechanical equipment. The auxiliary support pressure value can be adjusted to the required value without stopping the machine, thereby saving time, reducing the labor intensity of workers, and improving the safety of operation.

[0016] 2. When this application is used, based on the pressure obtained by the pressure sensor on the spherical washer, the output force of the oil cylinder is changed by adjusting the pressure reducing valve on the hydraulic station, thereby realizing the real-time adjustment of the auxiliary support force. This accurately and flexibly achieves effective unloading of the equipment, reduces the deformation of the mechanical equipment, and improves the overall rigidity of the equipment.

[0017] 3. This application detects the contact force value of the floating pad terminal by a pressure sensor and feeds it back to the operation interface. Operators and installation and commissioning personnel can intuitively see the actual force situation of each floating pad, providing an effective basis for setting and adjusting the auxiliary support force.

[0018] 4. When using this application, the pressure value preset by the floating pad mechanism can be kept constant by using an accumulator. At the same time, the high follow-up performance of the accumulator pressure replenishment can ensure that the supporting force between the floating pad mechanism and the mechanical equipment will not change due to changes in other external factors. In addition, the use of the accumulator can also greatly reduce the workload of the hydraulic station and obtain a more stable floating support effect.

[0019] 5. In use, the supporting force output by the floating pad mechanism of this invention is adjusted by a pressure reducing valve and detected by a pressure sensor. This allows the required supporting force value of the floating pad at each support position to be obtained through finite element analysis of the mechanical equipment under different working conditions. Then, as the mechanical equipment runs, the real-time pressure value transmitted by the pressure sensor in the operation interface is compared with the set standard value. Any differences are adjusted by the pressure reducing valve until the pressure sensor detects that the standard value has been reached. By repeating this operation, multi-point closed-loop control can be achieved.

[0020] 6. When using this application, the floating base plate mechanism of this invention has flexible arrangement. The layout of the floating base plate mechanism can be changed according to the changes in the bottom rib shape and contact boss of the mechanical equipment. At the same time, the placement position of the floating base plate mechanism can be set with the help of "finite element" analysis software, which is not affected by the fixed foundation position.

[0021] 7. This application utilizes the activation of a hydraulic cylinder to control the longitudinal movement of the hinged base, thereby causing the connecting support to move under the action of the hinged connecting rod, adjusting the distance between adjacent side support plates, and thus adjusting the height of the side support plates. At this time, when the side support plates are adjusted in longitudinal height, they can drive the intermediate support plate to move longitudinally. In use, both the intermediate support plate and the side support plates can support the bottom of the mechanical equipment, ensuring the stability of the mechanical equipment support. During this process, by using a set of hydraulic cylinders, the upper surface of the spherical washer can be controlled to be flush. Even under the activation of the hydraulic cylinders, the spherical washer can be kept stable when supporting the bottom of the mechanical equipment, ensuring the levelness of the bottom surface of the mechanical equipment.

[0032] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0033] Please see Figure 1-8 As shown, a closed-loop adjustable floating pad mechanism includes a pad base 4, which is positioned on the part of the mechanical equipment 9 that needs to be supported and unloaded by a pad mounting plate 10. A spherical washer 1 is provided on the pad base 4, which contacts the supported mechanical equipment 9 and provides support for the mechanical equipment 9. It also has an adaptive contact deflection angle. The spherical washer 1 is placed on a top sleeve 3. A pressure sensor 2 is fixedly placed between the spherical washer 1 and the top sleeve 3 to sense the pressure from the spherical washer 1. A hydraulic cylinder 5 is fixed on the pad base 4, which is connected to a hydraulic station 8 through a pressure reducing valve 6 and stores energy through an accumulator 7. The hydraulic station 8, accumulator 7, and pressure reducing valve 6 are each installed separately. The output end of the hydraulic cylinder 5 is fixedly installed on the spherical washer 1, and the longitudinal movement of the spherical washer 1 is controlled by the hydraulic cylinder 5.

[0034] In practical use, because the load of mechanical equipment 9 varies with different working conditions, the floating pad mechanism in this application can adjust the pressure reducing valve 6 on the hydraulic station 8 to change the output force of the oil cylinder 5 in response to the load changes of mechanical equipment 9, thereby realizing the non-stop adjustment of the auxiliary support force, thus accurately and flexibly achieving effective unloading of mechanical equipment 9, reducing the deformation of mechanical equipment 9, and improving the overall rigidity of mechanical equipment 9.

[0035] Specifically, the parts of the mechanical equipment 9 that need to be supported and unloaded are accurately positioned by each pad seat 4 via the pad mounting plate 10. Therefore, this application also includes calibration with a laser level to ensure that the contact surface on the spherical washer 1 is in an elevated state, thereby ensuring that when unloading the bottom of the mechanical equipment 9, the unloading force provided by each spherical washer 1 is the same, ensuring the stability of the unloading of the spherical washer 1. At the same time, the spherical washer 1 contacts the supported mechanical equipment 9, providing support while also adapting to the contact angle.

[0036] The spherical washer 1 is placed on the top sleeve 3, and the pressure sensor 2 is fixedly installed between the spherical washer 1 and the top sleeve 3. It is used to detect the supporting force of the spherical washer 1 in real time and send the supporting force data to the operation interface. This is used to monitor the supporting force data of each spherical washer 1. That is, by judging whether the unloading at the bottom center of the mechanical equipment 9 is stable, the bottom surface of the mechanical equipment 9 is monitored to ensure the stability of the mechanical equipment 9.

[0037] The hydraulic cylinder 5 is fixed on the pad base 4. After the foundation of the supported mechanical equipment 9 is fixed, the hydraulic cylinder 5 starts working through the hydraulic station 8 and accumulator 7 via the pressure reducing valve 6. The data fed back to the operating interface by the pressure sensor 2 is observed, and the output force of the hydraulic cylinder 5 is changed by adjusting the pressure reducing valve 6 to achieve the required value. The supporting force output by the floating pad mechanism of this application is adjusted by the pressure reducing valve 6. The pressure sensor 2 detects the required supporting force value of the floating pad at each support position, which is obtained by analyzing the mechanical equipment under different working conditions using finite element analysis. As the mechanical equipment 9 runs, the real-time pressure value transmitted by the pressure sensor 2 in the operating interface is compared with the set standard value. Any difference is adjusted by the pressure reducing valve 6 until the pressure sensor 2 detects that the standard value has been reached. This operation is repeated to achieve multi-point closed-loop control, thereby effectively and flexibly unloading the mechanical equipment 9, reducing the deformation of the base, and improving the overall rigidity and accuracy of the equipment.

[0038] During verification, the working condition of the finite element analysis can be set as follows: the upper surface of the equipment is subjected to a downward load of 400KN, and the maximum vertical deformation is 0.09mm when there is no pad support in the middle of the equipment.

[0039] During verification, the finite element analysis can be set to a working condition where the upper surface of the equipment is subjected to a downward load of 400KN. There are 16 floating pads evenly distributed at the middle boss under the 8.5m long and 2m wide equipment base. When the support force of each floating pad is set to 12KN, the maximum vertical deformation is only about 0.012mm.

[0040] Finite element analysis verification shows that the floating pad mechanism with closed-loop adjustment of the present invention can provide real, effective, accurate and reliable support for the supported mechanical equipment, effectively prevent deformation of the base after bearing load, and improve the overall rigidity and accuracy of the equipment.

[0041] As a further embodiment of this application, in use, multiple sets of hydraulic cylinders 5 individually support each spherical washer 1 to achieve intermediate unloading of the mechanical equipment 9. However, the level detection of the laser level depends not only on the fixed installation of the laser level, but also on the spherical washers 1 being in a fixed position. When the spherical washers 1 move longitudinally under the action of the hydraulic cylinders 5, the height of longitudinal movement of the spherical washers 1 driven by the hydraulic cylinders 5 may be affected by factors such as the start-up time of each hydraulic cylinder 5, resulting in errors in the top height of each spherical washer 1. This affects the unloading effect on the mechanical equipment 9 and may cause deformation of the bottom surface of the mechanical equipment 9, affecting the processing accuracy of the mechanical equipment 9.

[0042] To solve the above-mentioned technical problems, this application adopts the method of using multiple sets of spherical washers 1 to move longitudinally in coordination, so as to keep the height of the spherical washers 1 stable at all times, thereby ensuring that the unloading distribution on the bottom surface of the mechanical equipment 9 is more uniform and reducing the possibility of deformation on the bottom surface of the mechanical equipment 9.

[0043] Therefore, in order to ensure the height of each spherical washer 1, this embodiment uses a set of hydraulic cylinders 5 to control each spherical washer 1, so that the output height of the hydraulic cylinders 5 can directly control the height of the spherical washer 1, and the contact force between the spherical washer 1 and the mechanical equipment 9 remains consistent.

[0044] Specifically, in this application, the output end of the hydraulic cylinder 5 is fixed with a hinge base 25, and several sets of inclined slide rods 24 are fixed on the fixed sleeve of the hydraulic cylinder 5. An inclined limiting plate 22 is fixed at the end of the inclined slide rod 24, and an inclined slider 23 is slidably arranged on the inclined slide rod 24. A connecting support 13 is fixed at the end of the inclined slider 23, and a hinge connecting rod 12 is hinged on the side of the connecting support 13. The side of the hinge connecting rod 12 away from the connecting support 13 is hinged to the hinge base 25.

[0045] In use, the height of the hinge base 25 is controlled by starting the hydraulic cylinder 5, so that the inclined slider 23 slides on the inclined slide rod 24 under the action of the hinge connecting rod 12, thereby controlling the height of the connecting support 13. This allows the height of the support mechanism on the connecting support 13 to be controlled. In this application, by starting one set of hydraulic cylinders 5, several sets of inclined sliders 23 can be controlled to move longitudinally, thereby ensuring that the height of the support mechanism is constant while controlling the longitudinal movement of the support mechanism, reducing the problem of different output heights caused by the use of several sets of hydraulic cylinders 5.

[0046] The support mechanism includes a connecting rod 14, and a side support plate 21 is fixed at the end of the connecting rod 14. Several sets of support protrusions 16 are evenly arranged on the side support plate 21, and the support protrusions 16 are connected to a spherical washer 1 through a pressure sensor 2.

[0047] During use, the spherical washer 1 contacts the bottom of the mechanical equipment 9, and the pressure sensor 2 is used for real-time detection to ensure that each set of spherical washers 1 can contact and support the bottom surface of the mechanical equipment 9.

[0048] When only the side support plates 21 are used to support the bottom of the mechanical equipment 9, there is a large empty area in the middle of the adjacent side support plates 21, which leads to uneven distribution of the supporting force and affects the support of the middle position of the mechanical equipment 9.

[0049] Therefore, in this application, an intermediate support plate 19 is also provided between adjacent side support plates 21. The intermediate support plate 19 is provided with several sets of support protrusions 16 evenly. The intermediate support plate 19 is slidably connected to the side support plates 21. The longitudinal movement of the side support plates 21 is used to control the longitudinal movement of the intermediate support plate 19. In order to achieve the longitudinal sliding limit of the intermediate support plate 19 and ensure that the intermediate support plate 19 is always in the middle position between adjacent side support plates 21, a mounting base plate 18 is fixed on the side of the intermediate support plate 19. The mounting base plate 18 is mounted on the limiting slide rod 11, wherein the limiting slide rod 11 is slidably connected to the frame.

[0050] When the side support plate 21 moves longitudinally, it drives the middle support plate 19 to move longitudinally, so that the middle support plate 19 moves longitudinally under the action of the limiting slide rod 11, which enables the middle support plate 19 to move longitudinally in the center, ensuring that the middle support plate 19 is always located in the middle position of the adjacent side support plate 21.

[0051] In order to achieve a sliding connection between the side support plate 21 and the middle support plate 19, a side sliding groove 15 is provided inside the side support plate 21. A side slider 20 is slidably arranged inside the side sliding groove 15. A side sliding rod 17 is fixed on the side of the side slider 20. The side sliding rod 17 is fixedly connected to the middle support plate 19.

[0052] In this embodiment, the hydraulic cylinder 5 is activated to control the longitudinal movement of the hinge base 25. This causes the connecting support 13 to move under the action of the hinge connecting rod 12, which in turn causes the inclined slider 23 to slide under the action of the inclined sliding rod 24. This adjusts the position of the connecting support 13 and the distance between adjacent side support plates 21, thereby adjusting the height of the side support plates 21 and the intermediate support plate 19. When the side support plates 21 are adjusted longitudinally, they can drive the intermediate support plate 19 to move longitudinally. At this time, the side slider 20 slides inside the side sliding groove 15, thereby adjusting the height of the intermediate support plate 19. Subsequently, under the sliding connection between the limiting sliding rod 11 and the frame, the intermediate support plate 19 is always located in the middle position of the adjacent side support plates 21. In use, the intermediate support plate 19 can support the bottom of the mechanical equipment 9, and the side support plates 21 can also support the bottom of the mechanical equipment 9, ensuring the stability of the mechanical equipment 9.

[0053] As a further embodiment of this application, in order to ensure the stability of the base at the bottom of the mechanical device 9, when the mechanical device 9 is affected by gravity and movement, the base at the bottom of the mechanical device 9 will undergo lateral deformation or the position of the base will shift, which will affect the positional accuracy of the mechanical device 9. Therefore, this application applies the support protrusion 16, the side support plate 21, the middle support plate 19 and the linkage mechanism that pushes them to the side of the base at the bottom of the mechanical device 9. When the base at the bottom of the mechanical device 9 deforms or the position of the base shifts, the support protrusion 16 on the side is subjected to force, and the support protrusion 16 is used to push or apply force towards the middle position to ensure that the mechanical device 9 is relatively stable.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
