[0003] As the requirements for thin-walled parts inspection increase, the clamping platform for measuring and inspecting thin-walled parts has the following problems with the existing technology. First, when clamping thin-walled parts, the two sides are usually clamped by two driving mechanisms, and the setting of the two driving mechanisms will cause the clamping force on both sides to be different, which will cause the clamping position to shift and make it impossible to clamp accurately. Secondly, parts of different shapes cannot be fully fitted when clamped, which is inconvenient for clamping parts of different shapes. During clamping, the moving pressure of the clamping part is unbalanced, resulting in excessive or insufficient clamping force in the rear section, and it is impossible to protect when the clamping pressure is too high, which makes it easy to damage thin-walled parts when the clamping pressure is too high.

A motor mounting disk 26 is installed at the lower end of the fixed base 1, and a driving motor 27 is installed at the lower end of the motor mounting disk 26.

[0029] In this embodiment, support frames 2 are installed on both sides of the lower end of the fixed base 1. A plurality of screw holes 3 are provided at the bottom of the support frames 2. The two support frames 2 are symmetrically arranged and installed, and the support frames 2 play a role in supporting and fixing the platform.

[0030] In this embodiment, the movable slider 5 moves left and right around the movable guide rail 4, and the two movable mounting plates 6 are located on both sides above the movable guide rail 4. The movement of the movable slider 5 around the movable guide rail 4 plays a guiding and positioning role.

[0031] In this embodiment, a flexible magnetic column structure 9 is provided to clamp parts of different shapes. The flexible magnetic column structure 9 includes a telescopic sleeve 10, a telescopic moving block 11, a flexible top column 12, a supporting spring 13, an airtight moving block 14, a connecting column 15, a hollow cone head 16 and a sealing port 17. The telescopic sleeve 10 is installed on the inner side of the mounting plate 7 and the positioning sleeve 8. The flexible top column 12, the supporting spring 13 and the airtight moving block 14 are all installed inside the telescopic sleeve 10. The flexible top column 12, the supporting spring 13 and the airtight moving block 14 are installed in a line from left to right. The flexible top column 12 is installed at one end of the telescopic moving block 11, the connecting column 15 is installed at one end of the airtight moving block 14, the hollow cone head 16 is installed at the end of the connecting column 15 away from the airtight moving block 14, and the sealing port 17 is installed on one side of the inside of the telescopic sleeve 10.

[0032] In this embodiment, the flexible top column 12 passes through the outside of the telescopic sleeve 10, the support spring 13 is located between the flexible top column 12 and the airtight moving block 14, the flexible top column 12 and the airtight moving block 14 move left and right around the inside of the telescopic sleeve 10, the hollow cone head 16 is located on one side of the sealing port 17, the sealing port 17 is used to seal the inside of the telescopic sleeve 10, and the hollow cone head 16 pushes the sealing port 17 to open the seal.

[0033] In this embodiment, the flexible top column 12 is located on one side of the positioning sleeve 8, and multiple flexible top columns 12 are installed in a square array. The two groups of flexible top columns 12 are symmetrically arranged and installed. The clamping workbench 19 is located below the flexible top column 12, and the two groups of flexible top columns 12 clamp the parts on both sides of the clamping workbench 19.

[0034] In this embodiment, a clamping drive structure 21 is provided to drive the movable mounting plate 6 to move. The clamping drive structure 21 includes a rotating disk 22, a connecting rod 23, a driving rod 24 and a docking block 25. The rotating disk 22 is installed at the center of the rotating mounting groove 20, two connecting rods 23 are installed on the outside of the rotating disk 22, the driving rod 24 is installed at one end of the connecting rod 23, and the docking block 25 is installed at the end of the driving rod 24 away from the connecting rod 23. The driving rod 24 is movably connected to the connecting rod 23 through a rotating shaft, and the driving rod 24 is movably connected to the docking block 25. The two docking blocks 25 are respectively movably connected to the lower ends of the two movable mounting plates 6, the rotating disk 22 is movably connected to the fixed base 1, and the output end of the driving motor 27 is connected to the rotating disk 22. The driving motor 27 is used to drive the rotating disk 22 to rotate.

[0035] In this embodiment, the workbench mounting plate 18 is located above the rotating disk 22, the two movable mounting plates 6 are located on both sides of the workbench mounting plate 18, and the rotating disk 22 is hidden under the workbench mounting plate 18 to reduce the overall volume.

[0036] The clamping platform for measuring and detecting thin-walled parts, when in use, the fixed base 1 is the fixed part of the base, the parts are placed above the workbench mounting plate 18, and the operation of the driving motor 27 drives the rotating disk 22 to rotate. When the rotating disk 22 rotates, the two driving rods 24 are pulled toward the center through the connecting rod 23. Therefore, the driving rod 24 is connected with the movable mounting plate 6 through the docking block 25, and the two movable mounting plates 6 are pulled toward the center. At the same time, the movable slider 5 moves above the movable guide rail 4 to play a guiding and positioning role. After the two movable mounting plates 6 move toward the center, they drive the two groups of flexible top columns 12 to move to the sides of the parts above the workbench mounting plate 18, and then the two groups of flexible top columns 12 are attached to the two sides of the parts for clamping and fixing.

[0037] In order to evenly disperse the clamping force, the driving motor 27 drives the rotating disk 22 to rotate, and the rotating disk 22 then pulls the two driving rods 24 toward the center through the connecting rod 23. Finally, the docking block 25 pulls the two movable mounting plates 6 toward the center to achieve clamping. The rotating synchronous drive structure keeps the pulling force of the two driving rods 24 balanced and the pulling distance the same, so as to prevent the clamping position from being offset due to the different clamping forces of the two sets of flexible top columns 12, and to achieve more precise clamping.

[0038] In order to accommodate clamping of different shapes, when the flexible top column 12 is fitted on both sides of the component for clamping, the flexible top column 12 is installed at one end of the telescopic moving block 11, and the telescopic moving block 11 is pressed against one end of the support spring 13 inside the telescopic sleeve 10. Therefore, when the flexible top column 12 is subjected to force, the flexible top column 12 contracts into the telescopic sleeve 10, and drives the telescopic moving block 11 to move left and right in the telescopic sleeve 10, and cooperates with the support spring 13 to apply reverse force to the telescopic moving block 11 and the flexible top column 12 for tightening and clamping. At the same time, the design of multiple flexible top columns 12 allows some of the flexible top columns 12 to contract into the telescopic sleeve 10 when fitting components of different shapes, so that multiple flexible top columns 12 can fit components of different shapes for clamping, which is more convenient for clamping components of different shapes.

[0039] In order to clamp thin-walled parts more safely, when the flexible top column 12 is clamped in place of the parts, the support spring 13 is installed at the front section of the telescopic sleeve 10, and the rear end of the telescopic sleeve 10 is filled with high-pressure air. The high-pressure air plays a role of elastically supporting the airtight moving block 14. The support spring 13 supports the flexible top column 12 through the telescopic moving block 11, so that the flexible top column 12 is clamped. While clamping, the airtight moving block 14 moves at the rear end of the telescopic sleeve 10, and an elastic supporting force is also formed through the high-pressure air, so that the airtight moving block 14 and the support spring 13 are elastically supported and clamped at the same time. The two-section support structure can It is able to disperse the force more evenly, so that the moving pressure of the flexible top column 12 remains balanced, and the clamping force of the rear section is prevented from being too large or too small. When the driving clamping force output by the driving motor 27 is too large, the excessive pressure drives the airtight moving block 14 to move to one side of the telescopic sleeve 10, and drives the hollow cone head 16 to be inserted into the sealing port 17 through the connecting column 15, so that the sealing port 17 opens the seal in the telescopic sleeve 10, thereby discharging the high-pressure air in the telescopic sleeve 10, and the flexible top column 12 cannot be supported, and the clamping of the flexible top column 12 on the parts is instantly released, so as to prevent the damage to the thin-walled parts caused by the excessive clamping force of the flexible top column 12.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
