Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, and in particular to a floating lifting device. Background Technology

[0002] In industrial applications such as welding and pressing, commonly used lifting devices include a lifting cylinder and a support platform. The piston rod of the lifting cylinder is connected to the support platform, which is used to place the product to be processed or the supporting fixture. The lifting cylinder drives the piston rod to extend and retract, thereby raising and lowering the support platform in the vertical direction to complete the product processing flow.

[0003] Currently, the assembly and debugging process of the fixture and the support platform is complex, with extremely high requirements for installation accuracy. It takes a lot of time to calibrate the position, which seriously affects production efficiency. On the other hand, the overall structure of the lifting device is fixed and cannot be adaptively adjusted according to the product's own accuracy deviation. When the product has dimensional errors or insufficient surface flatness, it is easy to cause uneven force during processing, which in turn leads to problems such as poor product processing and fixture wear, making it difficult to meet the needs of high-precision processing scenarios.

[0004] Therefore, a floating lifting device is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a floating lifting device that is simple to assemble and debug, saves a lot of position calibration time, significantly improves production efficiency, avoids product defects and jig wear caused by uneven force during processing, and effectively improves product yield.

The lower surface of the support platform opposite to the support surface is provided with a spherical groove adapted to the floating ball. The inner wall of the spherical groove and the inner wall of the positioning through hole together wrap the floating ball. When the first connecting plate moves up and down in the vertical direction, the movement of the floating ball drives the support platform to move up and down in the vertical direction synchronously. When the support platform is subjected to external force, it can rotate and float around the floating ball to achieve adaptive adjustment of its horizontal posture.

[0012] As an alternative to the floating lifting device, the floating lifting device also includes a plurality of springs, which are evenly distributed circumferentially along the outer edge of the receiving groove. The first end of any spring is connected to the first connecting plate and the second end is connected to the support platform, which can flexibly support the support platform and is configured to provide a restoring force when the horizontal attitude of the support platform is adaptively adjusted, so as to maintain the dynamic balance of the support platform.

[0013] As an alternative to the floating lifting device, the floating lifting device further includes multiple adjusting screws. These adjusting screws are evenly distributed circumferentially along the first connecting plate, extend vertically, and are threaded through and connected to the first connecting plate. When the adjusting screws rotate relative to the first connecting plate, the extension length of the adjusting screw end through the first connecting plate and the gap between the adjusting screw end and the lower surface of the support platform can be adjusted to limit the maximum angle of rotation and floating of the support platform relative to the first connecting plate. When the ends of the multiple adjusting screws abut against the support platform and a preload is applied, the support platform is locked and fixed.

[0014] As an optional solution for the floating lifting device, the floating lifting device also includes a positioning pin. The second connecting plate is provided with a first positioning hole, and the support platform is provided with a corresponding second positioning hole.

[0015] As an alternative to the floating jacking device, the floating jacking device also includes a first fastening bolt that can pass through and fix the support platform and the second connecting plate, so that the support platform and the second connecting plate are detachably and fixedly connected.

[0016] As an alternative to the floating lifting device, the driving component is a lifting cylinder, and the first connecting plate is fixedly connected to the piston rod of the lifting cylinder.

The connecting screw passes through the first connecting plate and is threadedly connected to the floating ball, which is confined within the positioning through hole. The support platform is detachably fixed to the second connecting plate, so that the floating ball is jointly wrapped by the inner wall of the positioning through hole and the inner wall of the spherical groove, ensuring that the second connecting plate and the bottom wall of the receiving groove have a second adjustment gap in the vertical direction. When this floating lifting device is in operation, the product or fixture is supported on the support platform. The drive unit drives the first connecting plate to move vertically upward, causing the floating ball to move vertically upward synchronously, and lifting the support platform simultaneously upward. If the product has dimensional errors or insufficient flatness, the support platform is rotated and floated around the floating ball under external force. The horizontal posture is adaptively adjusted through the first and second adjustment gaps, stably pressing the product or fixture against the support surface of the support platform. After processing the product on the support platform, the drive unit drives the first connecting plate to move vertically downward, causing the floating ball to move vertically downward synchronously, and the support platform simultaneously descending vertically.

[0042] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1-5 As shown, this embodiment provides a floating lifting device, which includes a driving component 1, a first connecting plate 2, a floating ball 3, a connecting screw 4, a second connecting plate 5, and a support platform 6. The first connecting plate 2 is connected to the output end of the driving component 1, and the driving component 1 can drive the first connecting plate 2 to move up and down in the vertical direction. The first connecting plate 2 is provided with a receiving groove 20. The floating ball 3 is located at the center of the receiving groove 20. The connecting screw 4 passes through the first connecting plate 2 and is threadedly connected to the floating ball 3. The second connecting plate 5 is located in the receiving groove 20, and a first adjustment gap 201 is reserved between the second connecting plate 5 and the side wall of the receiving groove 20 in the horizontal direction. The bottom wall of the first connecting plate 6 has a second adjustment gap 202 reserved in the vertical direction. The second connecting plate 5 has a positioning through hole 51 that is adapted to the floating ball 3. The support platform 6 is detachably and fixedly connected to the second connecting plate 5. The support surface on the upper side of the support platform 6 can be used to place products or fixtures. The lower surface of the support platform 6 away from the support surface has a spherical groove 61 that is adapted to the floating ball 3. The inner wall of the spherical groove 61 and the inner wall of the positioning through hole 51 together wrap the floating ball 3. When the first connecting plate 2 moves up and down in the vertical direction, the floating ball 3 moves and drives the support platform 6 to move up and down in the vertical direction in sync. When the support platform 6 is subjected to external force, it can rotate and float around the floating ball 3 to achieve adaptive adjustment of the horizontal posture.

[0044] During installation, the second connecting plate 5 is placed into the receiving groove 20 of the first connecting plate 2, ensuring that the second connecting plate 5 and the side wall of the receiving groove 20 are reserved with a first adjustment gap 201 in the horizontal direction; the connecting screw 4 passes through the first connecting plate 2 and is threadedly connected to the floating ball 3, and the floating ball 3 is confined within the positioning through hole 51; the support platform 6 is detachably fixed to the second connecting plate 5, so that the floating ball 3 is jointly wrapped by the inner wall of the positioning through hole 51 and the inner wall of the spherical groove 61, ensuring that the second connecting plate 5 and the bottom wall of the receiving groove 20 are reserved with a second adjustment gap 202 in the vertical direction. When the floating lifting device is in operation, the product or fixture is supported on the support platform 6. The driving component 1 drives the first connecting plate 2 to move vertically upward, causing the floating ball 3 to move vertically upward synchronously, lifting the support platform 6 simultaneously. If the product has dimensional errors or insufficient flatness, the support platform 6 is rotated and floated around the floating ball 3 under external force. The horizontal posture is adaptively adjusted through the first adjustment gap 201 and the second adjustment gap 202, stably pressing the product or fixture onto the support surface of the support platform 6. After processing the product on the support platform 6, the driving component 1 drives the first connecting plate 2 to move vertically downward, causing the floating ball 3 to move vertically downward synchronously, and the support platform 6 to descend synchronously. Finally, the product or fixture is removed from the support platform 6. This floating lifting device is simple to assemble and debug, can float and press the product, can automatically adapt to the influence of the product's own precision, and has high consistency after the product is pressed. It saves a lot of position calibration time, significantly improves production efficiency, avoids product defects and fixture wear caused by uneven force during processing, and effectively improves product yield. Meanwhile, the support platform 6 and the second connecting plate 5 can be detached and fixed to adapt to different processing needs and fully meet the usage requirements of high-precision processing scenarios.

[0045] like Figure 4 As shown, it is worth noting that when the floating ball 3 moves upward in the vertical direction, the upper outer surface of the floating ball 3 abuts against the inner wall of the spherical groove 61, and the lifting support platform 6 moves upward in the vertical direction; when the floating ball 3 moves downward in the vertical direction, because the positioning through hole 51 covers the lower outer surface of the floating ball 3, and the maximum cross-sectional area of ​​the covered part of the lower part is smaller than the maximum cross-sectional area of ​​the uncovered part of the upper part, the uncovered part of the upper part of the floating ball 3 can push the second connecting plate 5 to move downward in the vertical direction. Since the second connecting plate 5 is connected to the support platform 6, it drives the support platform 6 to move downward in the vertical direction synchronously, ensuring that the second connecting plate 5 and the bottom wall of the receiving groove 20 always leave a second adjustment gap 202 in the vertical direction. To ensure stable transmission of the carrier platform 6 when the floating ball 3 rises and falls, and to prevent parts from detaching or jamming, the second connecting plate 5 and the bottom wall of the receiving groove 20 are always reserved with a second adjustment gap 202, so that the carrier platform 6 can rotate and float around the floating ball 3 at any time, flexibly adapt to product errors, prevent uneven processing force, reduce product defects and jig wear, and improve the operational stability and processing reliability of the floating lifting device.

[0046] like Figure 5 As shown, in this embodiment, the first adjustment gap 201 is 0.2 mm. In other embodiments, the first adjustment gap 201 can also be 0.4 mm, 0.6 mm, 0.8 mm, 1 mm, etc., and is not specifically limited here.

[0047] like Figure 2 , Figure 3 and Figure 6 As shown, the floating lifting device also includes multiple springs 7, which are evenly distributed circumferentially along the outer edge of the receiving groove 20. The first end of each spring 7 is connected to the first connecting plate 2, and the second end is connected to the support platform 6, providing flexible support for the support platform 6. This allows the springs to provide a restoring force during adaptive horizontal posture adjustment of the support platform 6, maintaining its dynamic balance. When the support platform 6 undergoes adaptive posture adjustment, the springs 7 provide a restoring force, helping the support platform 6 quickly maintain dynamic balance, reducing post-adjustment posture deviation, further ensuring the stability of the product under stress during processing, and reducing the risk of processing defects caused by posture fluctuations.

[0048] In this embodiment, there are four springs 7, which are evenly distributed circumferentially along the outer edge of the receiving groove 20. The two ends of each spring 7 are connected to the first connecting plate 2 and the support platform 6, respectively, providing balanced and flexible support to the support platform 6 from four directions. This avoids component wear caused by localized hard contact. When the horizontal posture of the support platform 6 is adaptively adjusted, the four springs 7 can simultaneously provide uniform restoring force, helping the support platform 6 to quickly and accurately maintain dynamic balance, reducing posture deviation after adjustment, further ensuring stable stress during product processing, and reducing the risk of processing defects caused by posture fluctuations. In other embodiments, the number of springs 7 can also be six, eight, etc., and is not specifically limited here.

[0049] It is worth noting that if the support platform 6 is not parallel to the horizontal direction, the product first contacts the highest point on the support surface. The reaction force pushes the support platform 6 to rotate and float around the floating ball 3 to adaptively level itself. For example, if the left side of the support surface is lower than the right side, the support platform 6 will adaptively tilt and float to the right, so that the right side of the product first fits with the right side of the support surface. As the support platform 6 rises, the left side of the product gradually fits with the left side of the support surface, ensuring a stable fit between the product and the support surface and preventing unstable fit due to the tilt of the support surface. If the product itself has a flatness error, such as a local dent, the spring 7 corresponding to the dent continuously pushes, and the support platform 6 rotates and floats, pressing the dent tightly against the support surface, effectively compensating for the flatness defect of the product itself. This ensures that regardless of whether the support surface is flat or whether the product has a flatness error, the product can maintain a stable and complete fit with the support surface, improving the reliability and adaptability of the floating lifting device.

[0050] like Figure 2 , Figure 3 and Figure 6As shown, the floating lifting device also includes multiple adjusting screws 8, which are evenly distributed circumferentially along the first connecting plate 2, extending vertically and threadedly connected to the first connecting plate 2. When the adjusting screws 8 rotate relative to the first connecting plate 2, the extension length of the adjusting screw 8 through the first connecting plate 2 and the gap between the end of the adjusting screw 8 and the lower surface of the support platform 6 can be adjusted to limit the maximum angle of rotation and floating of the support platform 6 relative to the first connecting plate 2. When the ends of the multiple adjusting screws 8 are all in contact with the support platform 6 and a preload is applied, the support platform 6 is locked and fixed. On the one hand, the multiple adjusting screws 8 are evenly distributed circumferentially along the first connecting plate 2, and their length extending through the first connecting plate 2 and the gap with the lower surface of the support platform 6 can be adjusted when rotating, which can accurately limit the maximum angle of rotation and floating of the support platform 6 and avoid excessive displacement affecting processing. On the other hand, when the ends of the multi-screw abut against the bearing platform 6 and apply pre-tightening force, the bearing platform 6 can be locked and fixed for product processing, adapting to different processing scenarios, taking into account both adaptive adjustment flexibility and fixed processing stability, and improving the applicability of the floating lifting device.

[0051] In this embodiment, there are four adjusting screws 8, which are evenly distributed around the first connecting plate 2. Each adjusting screw 8 can be rotated to adjust its length extending out of the first connecting plate 2 and its gap with the lower surface of the support platform 6. This allows for precise limitation of the maximum angle of rotation and floating of the support platform 6 from four directions, preventing excessive unilateral offset from affecting machining accuracy. When the ends of all four adjusting screws 8 abut against the support platform 6 and apply a balanced preload, the support platform 6 can be stably locked and fixed. This adapts to different machining scenarios, balancing adaptive flexibility and fixed stability, further improving the applicability and operational reliability of the floating lifting device. In other embodiments, the number of adjusting screws 8 can also be six, eight, etc., and is not specifically limited here.

[0052] like Figures 2-5 As shown, the floating lifting device also includes a positioning pin 10. The second connecting plate 5 has a first positioning hole 52, and the support platform 6 has a corresponding second positioning hole 62. One end of the positioning pin 10 is inserted into the first positioning hole 52, and the other end is inserted into the second positioning hole 62, to initially position the relative positions of the support platform 6 and the second connecting plate 5. On one hand, the positioning pin 10, with one end inserted into the first positioning hole 52 of the second connecting plate 5 and the other end into the second positioning hole 62 of the support platform 6, can quickly and initially position their relative positions, saving time spent on repeated calibration during assembly and improving installation efficiency. On the other hand, it ensures that when the support platform 6 is connected to the second connecting plate 5, the spherical groove 61 and the positioning through hole 51 are precisely aligned, avoiding misalignment that could cause deviations in the fit of the floating ball 3, ensuring the stability of the subsequent adaptive adjustment function of the floating lifting device, and reducing the impact of assembly errors on machining accuracy.

[0053] like Figures 1-3As shown, the floating lifting device also includes a first fastening bolt 91, which passes through and fixes the support platform 6 and the second connecting plate 5, allowing for a detachable and fixed connection between the support platform 6 and the second connecting plate 5. On one hand, the first fastening bolt 91 ensures a stable connection between the support platform 6 and the second connecting plate 5, preventing loosening during operation of the floating lifting device or adjustment of the support platform 6's posture. This ensures the precise fit between the spherical groove 61 and the positioning through hole 51 on the floating ball 3, further maintaining the overall operational stability of the floating lifting device. On the other hand, the detachable and fixed connection between the support platform 6 and the second connecting plate 5 facilitates easy disassembly and assembly, making subsequent maintenance and replacement of the support platform 6 or the second connecting plate 5 convenient.

[0054] like Figure 4 As shown, in this embodiment, the driving component 1 is a lifting cylinder, and the first connecting plate 2 is fixedly connected to the piston rod of the lifting cylinder. The extension and retraction of the piston rod of the lifting cylinder can drive the first connecting plate 2 to move up and down in the vertical direction. The cylinder driving method has a simple structure and is easy to maintain, meeting the stability and controllability requirements of high-precision machining for lifting actions.

[0055] In other embodiments, the driving component 1 can also be a hydraulic cylinder. The first connecting plate 2 is fixedly connected to the piston rod of the hydraulic cylinder, and the extension and retraction of the piston rod of the hydraulic cylinder can drive the first connecting plate 2 to move up and down in the vertical direction. The hydraulic cylinder can provide a large driving force, adapt to the needs of heavy-duty scenarios, and ensure the reliability of the lifting drive.

[0056] like Figure 7 As shown, the floating lifting device also includes a second fastening bolt 92. The second fastening bolt 92 passes through and fixes the first connecting plate 2 and the piston rod of the lifting cylinder to securely connect the first connecting plate 2 and the piston rod of the lifting cylinder. On the one hand, the second fastening bolt 92 passing through and fixing the first connecting plate 2 and the piston rod of the lifting cylinder can achieve a stable connection between the two, preventing loosening when the lifting cylinder drives the first connecting plate 2 to move up and down, and ensuring the stability and accuracy of power transmission. On the other hand, this bolt connection method is easy to disassemble and assemble, facilitating subsequent maintenance and replacement of the first connecting plate 2 or the lifting cylinder, reducing the maintenance time of the floating lifting device, and the pre-tightening force of the second fastening bolt 92 can ensure the elimination of connection gaps, further improving the power transmission efficiency of the drive component 1 and maintaining the overall operational reliability of the floating lifting device.

[0057] In this embodiment, grease is filled between the inner wall of the spherical groove 61 and the outer wall of the floating ball 3. On one hand, filling the space between the inner wall of the spherical groove 61 and the outer wall of the floating ball 3 with grease reduces frictional resistance during relative rotation and floating, allowing for smoother adaptive adjustment of the bearing platform 6's posture and preventing friction-induced jamming that could affect the accuracy of adaptive adjustment. On the other hand, the grease forms a protective layer on the contact surface, reducing wear between components, extending the service life of the floating ball 3 and the bearing platform 6, and preventing dust and impurities from entering the mating gap, ensuring long-term stable mating and maintaining the reliability of the adaptive function of the floating lifting device.

[0058] In this embodiment, grease is filled between the inner wall of the positioning through hole 51 and the outer wall of the floating ball 3. On the one hand, filling the space between the inner wall of the positioning through hole 51 and the outer wall of the floating ball 3 with grease reduces the frictional resistance during their relative movement, allowing the adaptive adjustment of the bearing platform 6 to be smoother and preventing friction jamming from affecting the accuracy of adaptive adjustment. On the other hand, the grease can form a protective layer on the contact surface, reducing wear and extending the life of the components. It can also prevent dust and impurities from entering the mating gap, ensuring a long-term stable fit between the positioning through hole 51 and the floating ball 3, and maintaining the overall reliability of the floating lifting device.

[0059] In this embodiment, the first connecting plate 2, the floating ball 3, the second connecting plate 5, and the support platform 6 are all made of metal. Metal materials have high strength and high wear resistance, can withstand the external forces during product processing and the frictional wear during long-term use, extend the service life of components, and can prevent components from deforming due to stress or environmental factors, thus meeting the structural rigidity requirements of high-precision processing scenarios.

[0060] In this embodiment, an anti-slip pad is provided on the bearing surface of the support platform 6. On the one hand, the anti-slip pad increases the friction between the product or fixture and the bearing surface, preventing the product or fixture from sliding or shifting when the bearing platform 6 is adjusted, thus ensuring accurate processing position. On the other hand, the anti-slip pad can buffer the hard contact between the product and the bearing surface, reducing impact damage to the product surface caused by processing vibrations. It can also adapt to products with different surface materials, further improving the adaptability of the floating lifting device to various processing scenarios and maintaining the stability of the processing process.
