Description

Technical Field

[0001] The invention relates to the field of machine tools, and in particular to a self-adaptive anti-vibration base for a numerically controlled double-column vertical lathe. Background Art

[0002] CNC twin-column vertical lathes are precision machining equipment widely used in the manufacturing industry. They generate significant cutting forces and vibrations during operation, requiring stable support. These machines typically require extremely high stability and vibration resistance to ensure the accuracy of the workpiece. Traditional machine tool bases often have limitations. They struggle to mitigate the negative effects of external vibrations or uneven surfaces, which not only affects the CNC lathe's machining accuracy but can also lead to rapid wear or damage.

[0003] With the development of science and technology, technicians in related fields have also made a lot of optimizations on the technical means for shockproofing of CNC lathes. In order to make a more accurate comparison, a Chinese patent with announcement number CN212552685U discloses a hardware processing lathe base with good shockproof performance, including a support plate, a slide groove, a slider one, a slider two, a transverse spring one and a transverse spring two; when in use, it buffers the vibration from the outside by pushing the transverse spring one and the transverse spring two, thereby preventing the vibration from affecting the processing accuracy of the workpiece, and making the processing accuracy of the lathe higher.

[0004] However, the above device still has some shortcomings in actual use: When in use, the device cushions vibrations during the metal processing process by means of compression springs 1 and 2 to prevent equipment failure, and cushions external vibrations by pushing transverse springs 1 and 2, thereby preventing vibrations from affecting the machining accuracy of the workpiece. However, in actual use, since the device directly contacts the ground through the mounting plate, the support plate and the machining jig thereon are limited and supported by support rods, vertical springs, and a plurality of compression springs 1 and 2, which are connected to the mounting plate limiter. In other words, the machining jig, etc., actually achieves its overall support effect for the machine tool through the hard contact between the mounting plate and the ground. The flatness and contact effect between the ground and the mounting plate greatly affect the overall stability of the machine tool. Although the mounting plate can be directly fixed to the ground by means of expansion screws, etc., to ensure relative stability during use, if the ground itself is not flat and has a certain slope, it is easy to cause the entire machine tool to be skewed, causing the machining jig and workpiece on the machine tool to be subjected to abnormal stress in the initial state, thereby causing the vibration amplitude to increase during machining.

[0005] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing technical means for shockproofing CNC lathes. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides an adaptive shock-proof base for a CNC double-column vertical lathe, comprising a supporting frame, wherein the upper limit of the supporting frame is connected to a connecting base for corresponding connection to a CNC lathe, and a shock-proof component is provided between the supporting frame and the connecting base, and the shock-proof component comprises: There are multiple swing guide rods, which are symmetrically distributed on both sides of the connecting base.

[0007] The connecting guide rod is arranged at the lower end of the connecting base, and its upper limit sleeve is provided with an adjustment support plate located between the supporting frame and the connecting base. The adjustment support plate is connected to the supporting frame limit through a connecting piece, and the posture of the adjustment support plate relative to the ground is adjusted through the connecting piece to keep the lathe as a whole always in a horizontal state.

[0008] The buffer spring is arranged between the connecting base and the supporting frame and is used for buffering and shockproofing.

[0009] Preferably, the connecting member includes a plurality of connecting tubes passing through the adjustment support plate, a sliding support rod axially extending from the connecting tube, a connecting cross plate is provided on the upper limit sleeve of the sliding support rod, and a vertical spring is commonly connected between the connecting cross plate and the supporting frame.

[0010] Preferably, the lower end of the connecting conduit is correspondingly connected to a suction cup made of a flexible material.

[0011] Preferably, one end of the buffer spring away from the connection base is connected to the supporting frame through a driven slider, and a vertical sliding groove is formed on the supporting frame corresponding to the driven slider.

[0012] Preferably, guide grooves are formed on the supporting frame corresponding to the plurality of swing guide rods.

[0013] Preferably, the two sides of the same driven sliding block are symmetrically connected with extension blocks inserted on the supporting frame, and the supporting frame is also provided with a limiting sliding groove connected to the vertical sliding groove corresponding to the extension block.

[0014] Preferably, the vertical slide groove, guide groove and limiting slide groove are all larger than the corresponding size settings of the driven slider, swing guide rod and extension block, so that the entire connecting base allows a certain degree of deflection adjustment.

[0015] Preferably, the connecting guide rod includes a limiting sleeve connected to the connecting base, a ball shaft rod connected to the adjustment support plate is inserted into the limiting sleeve, and the ball head end of the ball shaft rod is limitedly passed through the adjustment support plate to allow the adjustment support plate to be deflected and adjusted with the ball head end of the ball shaft rod as the axis.

[0016] Preferably, the sliding strut is hinged to the connecting transverse plate via a ball shaft.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. The present invention drives the connecting base and the lathe to be adaptively leveled according to different ground conditions through the mutual cooperation between the supporting frame and the connecting base, thereby avoiding the problem of abnormal force on the lathe caused by the skew state of the lathe after installation, thereby causing abnormal vibration.

[0018] 2. The present invention uses a shock-proof component to level the connecting base accordingly, and absorbs the vibration energy generated during lathe processing, thereby achieving the effect of adaptive leveling and buffering shockproofing of the lathe according to the ground conditions.

[0019] 3. The present invention drives the buffer spring to be twisted under force in the initial state by adjusting the connecting base and the buffer spring. The twisted buffer spring is applied to the connecting base and the lathe, which has a tendency to deflect relative to the ground. When the lathe is performing processing operations, it can more flexibly change its own state through the cooperation of the connecting base and the buffer spring according to the direction and strength of the vibration generated during processing, thereby achieving the effect of preventing and buffering the vibration of the lathe processing, further enhancing the adaptive adjustment ability of the vibration, reducing the transmission of vibration to the ground, and avoiding excessive damage to the lathe's own parts caused by vibration, thereby extending the service life of the lathe.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1 To the attached Figure 9 The embodiments of the present invention are described in detail.

[0032] The embodiment of the present application discloses an adaptive shock-proof base for a CNC double-column vertical lathe. The present application is mainly used in the process of processing workpieces by a CNC double-column vertical lathe. In terms of technical effect, the mutual cooperation between the supporting frame and the connecting base is achieved, so that the lathe and the connecting base can adaptively adjust their own postures according to different ground conditions, ensuring that the lathe remains parallel to the horizontal plane before installation and use, thereby avoiding the problem of abnormal vibration of the lathe due to the uneven installation posture of the lathe itself, and achieving the effect of adaptive shock-proof according to different ground conditions.

[0033] Example 1: Reference Figure 1 As shown, a CNC double-column vertical lathe adaptive shock-proof base includes a supporting frame 1. The supporting frame 1 is connected to a connecting base 10 for corresponding connection to a CNC lathe at an upper limit. A shock-proof component 2 is provided between the supporting frame 1 and the connecting base 10. During use, the supporting frame 1 is placed on the ground, and the lathe is restrained on the connecting base 10. The connecting base 10 and the CNC lathe are adjusted and controlled by the shock-proof component 2. The CNC lathe is kept horizontal at the beginning, avoiding vibration caused by abnormal loads generated by the lathe's own skew. At the same time, the shock-proof component 2 cushions the vibration during the lathe processing process, preventing the vibration from affecting the processing accuracy of the workpiece, thereby achieving the effect of shock-proofing and buffering the CNC lathe.

[0034] Reference Figure 2 As shown, the shockproof component 2 is used for shockproofing and shock absorption; specifically, the shockproof component 2 includes: There are multiple swing guide rods 20 symmetrically distributed on both sides of the connecting base 10 . One end of the swing guide rod 20 away from the connecting base 10 is slidably inserted on the supporting frame 1 .

[0035] The connecting guide rod 21 is arranged at the lower end of the connecting base 10, and its upper limit sleeve is provided with an adjustment support plate 22 located between the supporting frame 1 and the connecting base 10. The adjustment support plate 22 is connected to the supporting frame 1 through a connecting member 23. The posture of the adjustment support plate 22 relative to the ground is adjusted through the connecting member 23 so that the lathe as a whole always remains in a horizontal state.

[0036] The buffer spring 24 is symmetrically arranged on both sides of the connection base 10, and the other end is connected to the supporting frame 1 for buffering and shockproofing.

[0037] During use, the supporting frame 1 is limited to the ground, and the CNC lathe is limited to the connecting base 10. The posture of the adjustment support plate 22 relative to the ground is adjusted through the connecting piece 23, so that the lathe as a whole always remains in a horizontal state, so as to achieve the effect of adaptively adjusting the lathe posture according to the ground state, effectively avoiding the vibration caused by the skewed state of the lathe after installation, and achieving a shockproof effect. The vibration generated during lathe processing is buffered and absorbed by the deformation of the buffer spring 24 between the connecting base 10 and the supporting frame 1, avoiding the problem of large vibration amplitude of the entire equipment.

[0038] Reference Figure 3 As shown, the connecting member 23 is used to drive the connection base 10 and the lathe to adjust. Specifically, the connecting member 23 includes a plurality of connecting guides 230 that extend axially through the adjustment support plate 22. Sliding struts 231 extend axially through the connecting guides 230. A connecting cross plate 232 is provided as an upper limit sleeve on the sliding struts 231. A vertical spring 233 is connected between the connecting cross plate 232 and the support frame 1. By adjusting the distance between the sliding struts 231 and the connecting guides 230 on the adjustment support plate 22 relative to the support frame 1, the adjustment support plate 22 is deflected about the connecting guide rod 21, achieving the effect of adaptive leveling of the adjustment support plate 22, the connection base 10, and the lathe as a whole. In the initial state, the sliding struts 231 and the connecting cross plate 232 are driven by the connected vertical springs 233 to always slide and extend upward.

[0039] During use, after the lathe is limited on the connecting base 10, the lathe and the connecting base 10 exert downward pressure under the influence of their own gravity to drive the connecting guide rod 21, the adjustment support plate 22 and all the connecting pipes 230 to move downward, and after the connecting base 10 contacts the connecting cross plate 232, it also synchronously drives the connecting cross plate 232 and the sliding support rod 231 to slide downward, and drives the connected vertical springs 233 to be compressed. After the connecting pipe 230 moves downward and contacts the supporting frame 1, the connecting cross plate 232 and the sliding support rod 231 are driven further downward by the gravity of the lathe and the connecting base 10 until the connecting cross plate 232 is against the connecting pipe 230. At this time, several vertical springs 233 are further compressed.

[0040] Based on the above, when the vibration generated during lathe processing is transmitted to the vertical spring 233 and the buffer spring 24, it will drive several vertical springs 233 and the buffer spring 24 to produce elastic deformation. During the deformation process, the vertical springs 233 and the buffer spring 24 will absorb and store a portion of the extrusion force applied by the vibration, extending the duration of the impact force. According to the momentum theorem, the longer the duration of the impact force, the smaller the impact force. The elastic deformation of the vertical springs 233 and the buffer spring 24 reduces the impact force generated by the vibration, thereby reducing damage to the lathe equipment and improving the stability and life of the lathe equipment.

[0041] Further, refer to Figure 4 As shown, in order to improve stability during use, the lower end of the connecting tube 230 is connected to a suction cup 234 made of flexible material. The suction cup 234 is preferably made of highly elastic and wear-resistant material, such as polyurethane material. The gravity of the lathe and the connecting base 10 drives the connecting tube 230 and the suction cup 234 to move down and abut against the supporting frame 1. The suction cup 234 first abuts tightly against the supporting frame 1 and then undergoes flexible deformation. After the air between the suction cup 234 and the supporting frame 1 is discharged, the suction cup 234 is adsorbed on the supporting frame 1 due to the pressure difference between the inside and outside of the suction cup 234, thereby achieving the effect of increasing the stability of the connecting tube 230 and the connecting base 10 during use.

[0042] Reference Figure 4 As shown, considering that a vertical tangential force may be generated during the machining process of the lathe, causing the connecting base 10 and other components to move downward, the end of the buffer spring 24 away from the connecting base 10 is connected to the supporting frame 1 via a driven slider 240. A vertical slide groove 241 is formed on the supporting frame 1 corresponding to the driven slider 240. During use, after the downward tangential force is applied to the connecting base 10, the connecting base 10 drives the swing guide rod 20, the buffer spring 24, and the driven slider 240 to move downward synchronously, thereby avoiding the restriction of the supporting frame 1 on the driven slider 240, which would cause a hard resistance to the downward tangential force applied to the connecting base 10 and thus cause accidental damage to the lathe equipment.

[0043] When the lathe applies a lateral tangential force to the connecting base 10, it will drive the connecting base 10 to drive the swing guide rod 20 to slide to one side. The buffer spring 24 on one side of the moving direction of the connecting base 10 is compressed, while the buffer spring 24 on the other side of the connecting base 10 is stretched. At the same time, the lateral sliding of the connecting base 10 also synchronously drives the limiting sleeve 210, the ball shaft rod 211 and the adjusting support plate 22 to slide synchronously, thereby driving all the vertical springs 233 to be driven to tilt toward the direction of the lateral sliding of the connecting base 10. At this time, the vertical spring 233 close to the moving direction of the connecting base 10 is tilted and compressed, while the vertical spring 233 on the other side of the connecting base 10 is tilted and stretched. When the connecting base 10 is driven to slide laterally to the other side, the states of the buffer springs 24 and the vertical springs 233 on both sides of the connecting base 10 are correspondingly opposite, and so on, achieving the effect of adaptive buffering of vibration during lathe processing.

[0044] Reference Figure 4 As shown, guide grooves 25 are formed on the supporting frame 1 corresponding to several swing guide rods 20 to allow the swing guide rods 20 to be driven by the connecting base 10 to slide and adjust in the vertical direction, while limiting the sliding path of the swing guide rods 20 to avoid a large degree of deviation of the lathe and the connecting base 10 as a whole.

[0045] Reference Figure 4 As shown, in order to buffer the vibration during lathe processing through the buffer spring 24, the same driven slider 240 is symmetrically connected to the two sides with an extension block 26 inserted into the support frame 1. The support frame 1 is also provided with a limiting slot 260 corresponding to the extension block 26 and connected to the vertical slot 241. The limiting slot 260 limits the extension block 26, and the extension block 26 limits the driven slider 240, so that the driven slider 240 and the extension block 26 are allowed to slide and shift only along the vertical slot 241. When the transverse tangential force generated by the vibration is applied to the connecting base 10, the displacement of the connected buffer spring 24 is limited by the driven slider 240 and the extension block 26, so that the buffer spring 24 is driven by the connecting base 10 to stretch or contract.

[0046] Furthermore, refer to Figure 4 As shown, in order to avoid the close fit between the supporting frame 1 and the driven slider 240, the swing guide rod 20 and the extension block 26, which would cause obstruction when the driven slider 240, the swing guide rod 20 and the extension block 26 are driven to move or deflect, the vertical slide groove 241, the guide groove 25 and the limiting slide groove 260 are all larger than the corresponding dimensions of the driven slider 240, the swing guide rod 20 and the extension block 26, so that the overall connecting base 10 allows a certain degree of deflection adjustment.

[0047] Reference Figure 4As shown, in order to adjust the posture of the connecting base 10 and the lathe as a whole according to different ground conditions, the connecting guide rod 21 includes a limiting sleeve 210 connected to the connecting base 10, and a ball shaft rod 211 connected to the adjustment support plate 22 is inserted into the limiting sleeve 210. The ball head end of the ball shaft rod 211 is limitedly penetrated on the adjustment support plate 22 to allow the adjustment support plate 22 to be deflected and adjusted with the ball head end of the ball shaft rod 211 as the axis.

[0048] When in use, since the vertical slide groove 241, the guide groove 25 and the limiting slide groove 260 are all used to guide the driven slider 240, the swing guide rod 20 and the extension block 26 to slide in the vertical direction, and the vertical slide groove 241, the guide groove 25 and the limiting slide groove 260 are all larger than the corresponding size settings of the driven slider 240, the swing guide rod 20 and the extension block 26, so that the connecting base 10 as a whole is allowed to have a certain degree of deflection adjustment, and the lathe and the connecting base 10 are guided to slide vertically downward in the initial stage due to the influence of their own gravity, until the connecting guide tube 230 and the suction cup 234 conflict with the support frame 1.

[0049] At this time, if the lower side of the supporting frame 1 is a normal flat ground, several connecting tubes 230 and suction cups 234 are synchronously driven to press against the supporting frame 1, so that the suction cups 234 are adsorbed on the supporting frame 1. At the same time, the sliding amplitudes of several sliding struts 231 relative to the connected connecting tubes 230 are the same, and the compression amplitudes of the vertical springs 233 are also the same. The vertical springs 233 normally buffer the vibrations during lathe processing.

[0050] If the lower side of the supporting frame 1 is a ground with a certain slope (usually a relatively flat ground but with a slight slope due to slight deformation or ground subsidence), the supporting frame 1 is in a tilted state at the initial stage. During the process of the lathe and the connecting base 10 driving the adjusting support plate 22, the connecting guides 230 and the suction cup 234 to move downward, before the suction cup 234 and the connecting guide 230 are completely in contact with the supporting frame 1, the adjusting support plate 22, the limiting sleeve 210, the ball shaft rod 211, the connecting base 10 and the lathe are in a tilted state. The whole is still in a state of vertical downward movement. After one of the suction cups 234 and the connecting conduit 230 contacts the supporting frame 1 (generally the suction cup 234 and the connecting conduit 230 close to the higher side of the inclined supporting frame 1), due to the inclination of the supporting frame 1, the connecting base 10, the swing guide rod 20 and the lathe as a whole have a tendency to slide downward due to the influence of their own gravity. The downward movement of the lathe and the connecting base 10 forms a certain degree of deflection with the supporting frame 1, and they slide downward at the same time.

[0051] The several connecting tubes 230 and suction cups 234 on the adjustment support plate 22 will appear as the connecting tubes 230 and suction cups 234 on one side first contact the higher side of the support frame 1, and at the same time, the suction cups 234 on this side are completely adsorbed on the support frame 1, and the connecting cross plate 232 on this side slides to a state of conflict with the limiting sleeve 210, and the connecting tubes 230 and suction cups 234 on the other side then contact the lower side of the support frame 1, and the suction cups 234 are not completely adsorbed on the support frame 1, so that the adjustment support plate 22 is deflected with the ball head end of the ball shaft rod 211. At this time, the lathe, the connecting base 10, the adjustment support plate 22 and the swing guide rod 20 are relatively inclined to the support frame 1, and are relatively parallel to the horizontal plane, so as to complete the effect of adaptively adjusting the lathe posture according to the ground state, thereby effectively avoiding the vibration problem caused by the tilt of the lathe.

[0052] Further, refer to Figure 4 As shown, the sliding strut 231 is hinged to the connecting cross plate 232 through a ball shaft. Specifically, a ball head end is provided on the sliding strut 231, and a ball joint seat is provided on the corresponding ball head end on the connecting cross plate 232. The ball head end and the ball joint seat correspond to each other so that the connecting cross plate 232, the sliding strut 231, the vertical spring 233, the connecting guide tube 230 and the suction cup 234 can adaptively adjust the deflection and tilt state of the support plate 22.

[0053] Example 2: Reference Figure 5 As shown, based on Example 1, considering that when the supporting frame 1 is placed on a flat ground that is not a slope, the connecting base 10 and the lathe are also parallel to the horizontal plane, at this time, if only the elastic deformation of several buffer springs 24 and vertical springs 233 at the connecting base 10 is used to buffer the vibration during lathe processing, it requires the buffer springs 24 and vertical springs 233 themselves to have sufficient strength for support or buffering, which will lead to an increase in equipment cost, and the vibration during lathe processing will continuously drive the buffer springs 24 and vertical springs 233 to continuously be subjected to force and deformation, and may also cause the buffer springs 24 and vertical springs 233 to wear and fatigue prematurely, resulting in a decrease in their shock absorbing performance.

[0054] Based on the above, a mounting cavity is formed in the hollow interior of the connecting base 10, and a shock absorber 27 is limitedly connected in the mounting cavity. The shock absorber 27 includes a connecting sleeve 270 limited to the upper side of the mounting cavity, and a sliding link 271 is downwardly passed through the connecting sleeve 270. The upper end of the sliding link 271 is connected to a pressure ball 272 located in the connecting sleeve 270, and a compression spring 273 is sleeved on the sliding link 271 and located between the pressure ball 272 and the connecting sleeve 270. The lower end of the sliding link 271 passes through the connecting sleeve 270 and is hinged to a driven rocker arm 274 and a counterweight ball 275.

[0055] During use, when the lathe generates vibration during operation, the vibration is transmitted to the connecting base 10, causing the pressure ball 272 in the connecting sleeve 270 to be stressed, the pressure spring 273 to be compressed, and the sliding link 271 to move downward. At this time, the driven rocker arm 274 will swing with the hinge point between it and the bottom of the sliding link 271 as the axis. The counterweight ball 275 will generate a reverse force on the driven rocker arm 274 due to its own gravity, thereby offsetting part of the vibration energy. The swing of the gravity ball and the driven rocker arm 274 shares the force on the buffer spring 24 and the vertical spring 233, reducing their force deformation frequency, effectively avoiding premature wear and fatigue of the buffer spring 24 and the vertical spring 233 due to excessive force, and making the shock absorption performance of the entire adaptive shockproof base more stable and lasting.

[0056] Furthermore, to further enhance the shock-absorbing effect of the gravity ball, the pressure ball 272 slides against the compression spring 273. When the pressure ball 272, the sliding link 271, the driven rocker 274, and the gravity ball are subjected to an upward driving force, the pressure ball 272 tends to separate upward from the compression spring 273. At this point, the pressure ball 272, the sliding link 271, the driven rocker 274, and the gravity ball as a whole are affected by their own downward gravity, maintaining a dynamic abutment relationship between the pressure ball 272 and the compression spring 273. This dynamic relationship allows for more precise adjustment of the cushioning force based on changes in vibration, ensuring a timely response to vibrations of varying intensities.

[0057] Example 3: Reference Figure 8 As shown, on the basis of Example 1 and Example 2, when on a sloping ground, due to the deflection and tilt of the connecting base 10 and the lathe relative to the supporting frame 1, the buffer springs 24 on both sides of the connecting base 10 are also applied with a certain relative torsional force and tensile force as the connecting base 10 deflects and tilts, that is, the buffer springs 24 on both sides of the connecting base 10 are stretched and relatively twisted in the initial stage, and at this time, the stress applied to the connecting base 10 by the twisted buffer springs 24 is in a relatively balanced state with the driving force of the lathe and the connecting base 10 itself due to the downward movement of gravity.

[0058] Based on the above, after the lathe generates vibration and forms a vertical tangential force applied to the connecting base 10, the buffer spring 24 will be further driven to be stretched (that is, the overall balance state of the buffer spring 24 and the connecting base 10 is broken). After the vertical tangential force applied by the lathe is reduced, the two buffer springs 24 that have been stretched and twisted will retract and rotate a certain amplitude because they need to restore their normal extended state, so as to absorb the vibration energy generated by the lathe vibration, thereby achieving the effect of further buffering the vibration during lathe processing.

[0059] During operation: The first step is to place the supporting frame 1 on the ground and fix the CNC lathe on the connecting base 10. The lathe and the connecting base 10 move downward as a whole under the action of their own gravity, and drive the shock-proof component 2 to adjust the posture of the connecting base 10 relative to the supporting frame 1 so that the connecting base 10 and the lathe remain parallel to the horizontal plane.

[0060] Step 2: After completing the adaptive leveling of the connection base 10 and the lathe, the vibration generated by the lathe during the processing is transmitted to the buffer springs 24 and the vertical springs 233, driving the buffer springs 24 and the vertical springs 233 to undergo elastic deformation. The deformation of the buffer springs 24 and the vertical springs 233 absorbs the vibration energy during the lathe processing, thereby achieving the effect of buffering vibration.

[0061] Step 3: After the connecting base 10 and the lathe are leveled on the sloping ground, due to the deflection of the connecting base 10 relative to the supporting frame 1, several buffer springs 24 connected to it are twisted, so that in the initial stage, a force is applied to the connecting base 10 and the lathe as a whole, which tends to drive the connecting base 10 and the lathe to rotate to be parallel to the bottom of the supporting frame 1, thereby preventing the lathe from vibrating.

[0062] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive.

[0063] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
