[0020] In the present invention, a movable long board is provided. When the two movable clamping blocks are pressed against the left and right ends of the workbench, the lifting board is pulled downward. At this time, the lifting board drives the limit column and the telescopic rod to descend. At this time, the limit column squeezes the spring so that the lifting board is located at the lower end position of the workbench table surface. The movable long board is pulled out so that the movable long board is pressed against the lower end of the workbench, making the platform body more stable on the workbench table surface and improving the fixing effect of the platform body.

[0021] In the present invention, by providing a limit block, when the movable long board moves, it will drive the limit block to move synchronously along the direction of the limit groove.

[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0025] See also Figures 1-8 The present invention provides a flexible motion platform that is easy to install, including a platform body 1, a terminal platform 30 is provided on the upper surface of the platform body 1, and a workbench 3 is provided at the lower end of the platform body 1, the lower surface of the platform body 1 is fixedly connected to the device base 2, and the lower surface of the device base 2 is movably connected to the upper surface of the workbench 3, a groove 9 is provided on the right surface of the device base 2, a long rod 19 is provided inside the groove 9, and both ends of the long rod 19 are rotatably connected to the inner wall of the device base 2, a knob 4 is provided at the rear end of the device base 2, and the rear surface of the device base 2 is provided with a A hole 8 is provided through the knob 4, and the front surface of the knob 4 is fixedly connected to the rear surface of the long rod 19 through the hole 8. A rotating bevel gear 18 is provided at both ends of the long rod 19, and a hole 4 29 is provided through the front surface of each rotating bevel gear 18. Each rotating bevel gear 18 is fixedly connected to the long rod 19 through the hole 4 29, and the left and right ends of each rotating bevel gear 18 are vertically meshed with a meshing bevel gear 17, and each meshing bevel gear 17 is fixedly connected to a short rod 14 on a side away from the rotating bevel gear 18, and each meshing bevel gear 17 is provided at one end away from the rotating bevel gear 18. There is a fixed plate 15, and each fixed plate 15 is fixedly connected to the inner wall of the device base 2. A second hole 16 is opened on the right surface of each fixed plate 15. Each short rod 14 passes through the second hole 16 and is connected to the meshing bevel gear 17, so that the short rod 14 can rotate relative to the second hole 16. The side of each short rod 14 facing away from the rotating bevel gear 18 is fixedly connected with a threaded rod 13. When the knob 4 is rotated, the knob 4 drives the long rod 19 to rotate. At this time, the two rotating bevel gears 18 rotate synchronously, and the four meshing bevel gears 17 meshing with the rotating bevel gear 18 will drive the short rod 14 to rotate. The four short rods 14 drive the four threaded rods 13 to continue rotating. Since the movable column 7 does not rotate, the movable columns 7 at both ends of the device base 2 will drive the movable clamping blocks 5 to move until the movable clamping blocks 5 are tightly against the two sides of the workbench 3, thereby achieving the purpose of installing the platform body 1. Since the distance between the two movable clamping blocks 5 can be controlled by rotating the knob 4, the platform body 1 can be installed on workbenches 3 of different sizes, avoiding the problem that the flexible motion platform cannot adapt to workbenches 3 of different sizes, which makes the flexible motion platform complicated and cumbersome during installation, thereby improving the convenience of installation.

[0026] The fixed plate 15 is rotatably connected to the short rod 14, so that there will be no positional offset when the rotating bevel gear 18 transmits force to the meshing bevel gear 17, making the rotating bevel gear 18 and the meshing bevel gear 17 more stable during transmission, and there will be no problems such as poor meshing, tooth jumping, sliding, or intermittent transmission, thereby improving the stability of the meshing gear transmission and the stability of the movement of the movable column 7.

[0027] Four movable columns 7 corresponding to the positions of the threaded rods 13 are provided inside the device base 2, and a thread groove 10 is provided on the end of each movable column 7 facing the threaded rod 13. Each movable column 7 is threadedly connected to the corresponding threaded rod 13 through the thread groove 10. Movable clamping blocks 5 are provided on the left and right ends of the device base 2, and a rubber pad 11 is fixedly connected to the opposite side of each movable clamping block 5. The side of each movable clamping block 5 facing the device base 2 is fixedly connected to the corresponding two movable columns 7.

[0028] Each movable clamping block 5 is provided with four grooves 21 (vertically arranged cylindrical holes or rectangular slots) inside, and each movable clamping block 5 is movably connected to the limiting column 20 through the four grooves 21. The lower surface of each limiting column 20 is fixedly connected with a spring 23, and the lower surface of each spring 23 is fixedly connected to the inner wall of the corresponding movable clamping block 5 (that is, the inner wall of the groove 21). A lifting plate 6 is provided at the lower position of each movable clamping block 5, and a hole three 22 is penetrated on the lower surface of each movable clamping block 5 (the hole three 22 is connected with the groove two 21, and the size of the hole three 22 is smaller than the groove two 21). A telescopic rod 12 is provided inside each groove two 21, and each spring 23 is movably connected to the corresponding telescopic rod 12.

[0029] The upper surface of each telescopic rod 12 is fixedly connected to the lower surface of the corresponding limit column 20 (the diameter of the limit column 20 is larger than the telescopic rod 12), and the lower surface of each telescopic rod 12 passes through the hole three 22 and is fixedly connected to the upper surface of the corresponding lifting plate 6. The two lifting plates 6 are provided with a groove three 24 on the opposite side. Each lifting plate 6 is movably connected to a movable long plate 28 through the groove three 24. When the two movable clamping blocks 5 are tightly against the left and right ends of the workbench 3, the lifting plate 6 is pulled downward. At this time, the lifting plate 6 drives the limit column 20 and the telescopic rod 12 to descend. At this time, the limit column 20 squeezes the spring 23, so that the lifting plate 6 is located at the lower end position of the workbench 3 table surface, and the movable long plate 28 is pulled out so that the movable long plate 28 is against the lower end of the workbench 3, making the platform body 1 more stable on the workbench 3 table surface, thereby improving the fixing effect of the platform body 1.

[0030] The upper surface of each movable long board 28 is fixedly connected with a rubber pad 27, and the left and right ends of the two movable long boards 28 are fixedly connected with the limit blocks 26. The inner walls of the two lifting plates 6 are provided with limit grooves 25 corresponding to the positions of the limit blocks 26. When the movable long boards 28 move, they will drive the limit blocks 26 to move synchronously along the direction of the limit grooves 25. When the movable long boards 28 move to a certain distance, the limit blocks 26 will resist the lifting plates 6, avoiding the problem of excessive movement of the movable long boards 28 causing the movable long boards 28 to fall off the lifting plates 6, thereby improving the stability of the movable long boards 28 during movement.

[0031] When the movable clamping block 5 is pressed against the workbench 3, the rubber pad 11 will provide a buffering effect for the movable clamping block 5, thereby preventing the movable clamping block 5 from excessively squeezing the workbench 3 and causing damage to the workbench 3. At the same time, when the movable long board 28 is pressed against the lower end of the workbench 3, the rubber pad 2 27 located on the upper surface of the movable long board 28 also provides a buffering effect, thereby improving the service life of the workbench 3.

[0032] Working principle: The first step is to rotate the knob 4. The knob 4 drives the long rod 19 to rotate. At this time, the two rotating bevel gears 18 rotate synchronously. The four meshing bevel gears 17 engaged with the rotating bevel gear 18 will drive the short rod 14 to rotate. The four short rods 14 drive the four threaded rods 13 to continue to rotate. Since the movable column 7 does not rotate, the movable column 7 at both ends of the device base 2 will drive the movable clamp 5 to move until the movable clamp 5 is tightly against the two sides of the workbench 3, thereby achieving the purpose of installing the platform body 1. Since the spacing between the two movable clamps 5 can be controlled by rotating the knob 4, the platform body 1 can be installed on workbenches 3 of different sizes, avoiding the problem that the flexible motion platform cannot adapt to workbenches 3 of different sizes, making the flexible motion platform complicated and cumbersome during installation, thereby improving the convenience of installation.

[0033] In the second step, the fixed plate 15 is rotatably connected to the short rod 14, so that the rotating bevel gear 18 will not be offset when transmitting force to the meshing bevel gear 17, making the rotating bevel gear 18 and the meshing bevel gear 17 more stable during transmission, and there will be no problems such as poor meshing, tooth jumping, sliding, or intermittent transmission, thereby improving the stability of the meshing gear transmission. When the mobile clamping block 5 is tightly against the workbench 3, the rubber pad 11 will provide a buffering effect for the mobile clamping block 5, avoiding the problem that the mobile clamping block 5 is damaged due to excessive squeezing of the workbench 3. At the same time, when the mobile long plate 28 is against the lower end of the workbench 3, the rubber pad 27 also provides a buffering effect, thereby improving the service life of the workbench 3.

[0034] In the third step, when the two movable clamping blocks 5 are tightly against the left and right ends of the workbench 3, the lifting plate 6 is pulled downward. At this time, the lifting plate 6 drives the limit column 20 and the telescopic rod 12 to descend. At this time, the limit column 20 squeezes the spring 23, so that the lifting plate 6 is located at the lower end position of the workbench 3 table surface, and the movable long plate 28 is pulled out so that the movable long plate 28 is against the lower end of the workbench 3, making the platform body 1 more stable on the table surface of the workbench 3, thereby improving the fixing effect of the platform body 1. When the movable long plate 28 moves, it will drive the limit block 26 to move synchronously along the direction of the limit groove 25. When the movable long plate 28 moves to a certain distance, the limit block 26 will against the lifting plate 6, avoiding the problem of excessive movement of the movable long plate 28 causing the movable long plate 28 to fall off the lifting plate 6, thereby improving the stability of the movable long plate 28 when moving.

Many modifications and variations will be apparent to those skilled in the art.
