Description

Technical Field

[0001] This application relates to the field of load platforms, and in particular to high-load positioning platforms. Background Technology

[0002] A load platform is a platform used to support and fix instruments and equipment. It has the advantages of being robust, stable, lightweight and flexible, making it widely used in precision machining, testing and measurement.

[0003] Commercial high-load positioning platforms generally adopt traditional cylinder actuation structures, but the transmission accuracy and response speed of cylinder actuators can no longer meet the current requirements for precision linear drive.

[0004] When using a positioning platform, the platform may become unstable under heavy loads, resulting in unsatisfactory height adjustments. This affects the platform's load-bearing capacity and makes it prone to damage under heavy loads, thus reducing the lifting effect of the linear positioning platform. Utility Model Content

[0005] To ensure stable load bearing and facilitate adjustment of the positioning platform, this application provides a high-load positioning platform.

[0006] The high-load positioning platform provided in this application adopts the following technical solution:

[0007] The system includes a positioning platform mounted on a base. A fixed track is fixedly mounted on the top of the base. Two movable blocks are slidably sleeved on the outer side of the fixed track. A push cylinder is fixedly mounted on the top of the base. A support rod is fixedly passed through the inner side of the movable block. Support wheels are fixedly mounted on the outer sides of both ends of the support rod. Two parallel support plates are fixedly mounted on the bottom of the positioning platform. Two guide grooves are opened on one side of each support plate.

[0008] By adopting the above technical solution, the moving block is driven by the cylinder to move horizontally along the fixed track. This allows the moving block to drive the support rod and support wheel to move. The support wheel moves along the guide groove on the inner side of the support plate, which can lift the support plate and change the height of the positioning platform. The horizontal thrust can reduce the pressure on the cylinder support to bear the load and improve the pressure-bearing effect of the linear positioning platform.

[0009] Preferably, four sets of support members are fixedly installed on the top of the base, each set of support members includes a fixed cylinder, and a support column is slidably sleeved on the inner side of the fixed cylinder.

[0010] By adopting the above technical solution, the support column can move and support itself within the fixed cylinder, allowing the length of the support column to be adjusted along the fixed cylinder.

[0011] Preferably, a protective component is fixedly installed on the top outer side of the fixed cylinder, and a fixed cover matching the protective component is fixedly installed on the top of the support column.

[0012] By adopting the above technical solution, it is easy to position and connect the protective component with the fixed cover. After the positioning platform is lowered, the protective component can position and fix the fixed cover, reducing the support pressure of the support plate at the bottom of the positioning platform on the support rod and reducing the load on the support rod under heavy load.

[0013] Preferably, the top of the fixing cover is fixedly installed with the bottom of the positioning platform, the top of the support column is fixedly installed with the bottom of the positioning platform, and the fixing cylinder and the support column are concentrically arranged.

[0014] By adopting the above technical solution, it is easy to position and connect the protective component with the fixed cover. After the positioning platform is lowered, the protective component can position and fix the fixed cover, so that the positioning platform can withstand large loads.

[0015] Preferably, the support wheel is rolled to the guide groove, a connecting block is fixedly installed between the two movable blocks, and the connecting block is slidably installed to the fixed track.

[0016] By adopting the above technical solution, it is easy to connect the two movable blocks. When the connecting block moves along the fixed track, the movable block can drive the support rod and support wheel to move. The support wheel drives the support plate to move along the guide groove, and the positioning platform on the top of the support plate can be adjusted in height for positioning operation.

[0017] Preferably, a plurality of balls are fixedly installed at the bottom of the connecting block, and a groove is provided at the top of the fixed track, and the balls roll in contact with the groove.

[0018] By adopting the above technical solution, the rolling arrangement of the ball bearings at the bottom of the connecting block and the fixed track facilitates the sliding movement of the movable block along the fixed track, making it easier to position and adjust the positioning table.

[0019] Preferably, the connecting block is slidably mounted to the slide groove via ball bearings, and the output end of the pushing cylinder is fixedly connected to the movable block.

[0020] By adopting the above technical solution, the cylinder drives the movable block to move along the fixed track, which facilitates the support movement of the support rod and support wheel driven by the movable block on the inner side of the support plate, so that the positioning table can perform load-bearing and pressure-bearing positioning operation on the item.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By pushing the cylinder to drive the movable block to move horizontally and stably along the fixed track, the movable block can drive the support rod and support wheel to move. The support wheel moves along the inner side of the support plate, lifting the support plate and changing the height of the positioning platform. This reduces the pressure on the push cylinder support under the load, protects the normal use of the push cylinder, and improves the pressure-bearing effect of the linear positioning platform.

[0023] 2. By positioning and docking the protective component with the fixed cover, the protective component can fix the fixed cover in place, reducing the support pressure of the support plate at the bottom of the positioning platform on the support rod. With the rolling setting of the ball bearings at the bottom of the connecting block and the fixed track, the movable block can slide along the fixed track, which facilitates the positioning and adjustment of the positioning platform. The positioning platform can bear the load of the item, solving the problem of damage under heavy load. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0031] This application discloses a high-load positioning platform.

[0032] The system includes a positioning platform 2 installed above the base 1. A fixed track 7 is fixedly installed on the top of the base 1. Two movable blocks 12 are slidably sleeved on the outer side of the fixed track 7. A push cylinder 3 is fixedly installed on the top of the base 1. A support rod 14 is fixedly passed through the inner side of the movable block 12. Support wheels 15 are fixedly installed on the outer sides of both ends of the support rod 14. Two parallel support plates 4 are fixedly installed at the bottom of the positioning platform 2. Two guide grooves 16 are opened on one side of the support plate 4.

[0033] By setting up a fixed track 7, a movable block 12, a support rod 14, and a support wheel 15, the movable block 12 can be pushed horizontally along the fixed track 7 by the push cylinder 3. This allows the movable block 12 to drive the support rod 14 and the support wheel 15 to move. The support wheel 15 moves along the guide groove 16 on the inner side of the support plate 4, which can lift the support plate 4 and change the height of the positioning platform 2. The horizontal thrust can reduce the pressure on the push cylinder 3 to bear the load and improve the pressure-bearing effect of the linear positioning platform.

[0034] Reference Figure 1 , Figure 4 Four sets of support components are fixedly installed on the top of the base 1. Each set of support components includes a fixed cylinder 5, and a support column 6 is slidably sleeved on the inner side of the fixed cylinder 5.

[0035] By setting a fixed cylinder 5, the support column 6 can move and support within the fixed cylinder 5, allowing the length of the support column 6 to be adjusted along the fixed cylinder 5.

[0036] Reference Figure 1 , Figure 2 , Figure 3 A protective component 8 is fixedly installed on the top outer side of the fixed cylinder 5, and a fixed cover 9 matching the protective component 8 is fixedly installed on the top of the support column 6; the top of the fixed cover 9 is fixedly installed on the bottom of the positioning platform 2, the top of the support column 6 is fixedly installed on the bottom of the positioning platform 2, and the fixed cylinder 5 and the support column 6 are concentrically arranged.

[0037] By setting up the protective component 8 and the fixing cover 9, it is easy to position and connect the protective component 8 and the fixing cover 9. After the positioning platform 2 is lowered, the protective component 8 can position and fix the fixing cover 9, thereby reducing the support pressure of the support plate 4 at the bottom of the positioning platform 2 on the support rod 14 and reducing the bearing pressure on the support rod 14 under heavy load.

[0038] Reference Figure 3 , Figure 4 The support wheel 15 is rolled and installed with the guide groove 16. A connecting block 13 is fixedly installed between the two movable blocks 12. The connecting block 13 is slidably installed with the fixed track 7.

[0039] By setting the connecting block 13, it is easy to connect the two movable blocks 12. When the connecting block 13 moves along the fixed track 7, the movable block 12 can drive the support rod 14 and the support wheel 15 to move. The support wheel 15 drives the support plate 4 to move along the guide groove 16, and the positioning platform 2 on the top of the support plate 4 is adjusted in height for positioning operation.

[0040] Reference Figure 4 , Figure 5 Multiple balls 10 are fixedly installed at the bottom of the connecting block 13, and a groove 11 is provided at the top of the fixed track 7. The balls 10 roll in contact with the groove 11. The connecting block 13 is slidably installed through the balls 10 and the groove 11, and the output end of the pushing cylinder 3 is fixedly connected to the movable block 12.

[0041] By setting a fixed track 7 and a slide 11, the ball bearings 10 at the bottom of the connecting block 13 are rolled along the fixed track 7, allowing the movable block 12 to slide along the fixed track 7. This facilitates the positioning and adjustment of the positioning platform 2, which can then bear the load on the item.

[0042] The implementation principle of the high-load positioning platform in this embodiment is as follows: When positioning the positioning platform 2 at a higher height, the moving block 12 is driven by the cylinder 3 to move horizontally along the fixed track 7. The moving block 12 drives the support rod 14 and support wheel 15 to support the support plate 4, so that the support wheel 15 moves along the guide groove 16, causing the support plate 4 to move and position the positioning platform 2 at a higher height. The support column 6 moves vertically along the fixed cylinder 5. When positioning the positioning platform 2 at a lower height, the moving block 12 is pulled along the fixed track by the cylinder 3. The horizontal movement of the guide 7 can drive the support rod 14 and support wheel 15 through the movable block 12 to support the support plate 4, so that the support wheel 15 moves along the guide groove 16, and the support plate 4 drives the positioning table 2 to adjust its height, so that the positioning table 2 lowers its height for positioning. When the protective part 8 and the fixed cover 9 are in contact, the positioning table 2 can withstand a large load, and the support rod 14 can be protected from pressure under a large load when receiving items, so that it can be better supported and used normally.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
