DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Example

[0026] The present invention provides a three-axis simulation test turntable, such as Figures 1 to 6 As shown, a three-axis simulation test turntable includes: a base 1, a turntable 2 is rotatably connected to the top of the base 1, an outer frame 3 is rotatably connected inside the turntable 2, and an inner frame 4 is rotatably connected inside the outer frame 3;

[0027] An automatic balancing structure 5 is installed inside the base 1, and the automatic balancing structure 5 includes a partition plate 51 fixed to the inner wall of the base 1, and thirty-six connecting covers 53 are fixedly installed at the bottom of the partition plate 51. A slider 54 is slidably connected inside the connecting cover 53, and a screw rod 55 is rotatably connected inside the slider 54. A balancing block 56 is threadedly connected to the outside of the screw rod 55 inside the slider 54, and a connecting rope 58 is connected between two relatively balancing blocks 56. Two balancing blocks 56 and the connecting rope 58 form a group, and there are eighteen groups in total. Electric telescopic rods 59 are fixedly installed on the top of the eighteen groups of sliders 54. One end of the base 1 is connected to a control device through a connecting line, and the control device is used to control the rotation of the turntable 2 inside the base 1 and the operation of the electric telescopic rod 59.

[0028] like Figure 4 and Figure 5As shown, a connecting column 52 is welded between the bottom end of the partition plate 51 and the top end of the connecting cover 53, a guide cover 57 is fixedly installed in the middle of the bottom end of the partition plate 51, and a connecting rope 58 is separated and penetrates the inside of the guide cover 57, a positioning block 510 is fixedly installed on the top end of the electric telescopic rod 59, and the positioning block 510 and the outer side of the guide cover 57 are fixedly connected, and the eighteen electric telescopic rods 59 are arranged in a circular array with equal distances based on the center point of the partition plate 51, and the eighteen electric telescopic rods 59 are symmetrically staggered about the center line of the X-axis, the slider 54 and the balance block 56 have the same shape, and a matching groove is opened inside the connecting cover 53 corresponding to the outer side of the balance block 56;

[0029] When the electric telescopic rod 59 is in operation, it drives one of the balancing blocks 56 to rise. When the balancing block 56 rises, it drives the connecting rope 58 to move. When the connecting rope 58 moves, the other balancing block 56 moves inside the connecting cover 53. When the turntable 2 has deviation due to rotation at this time, the height between the two balancing blocks 56 is adjusted to offset the axial position of the turntable 2, so that the turntable 2 remains balanced, further increasing the stability of the objects inside the turntable 2 during the detection process.

[0030] like Figure 2 and Figure 6 As shown, a side painting structure 6 is fixedly installed on one end surface of the turntable 2, and the side painting structure 6 includes a mounting frame 61 fixedly installed on the turntable 2, a guide frame 62 is slidably connected inside the mounting frame 61, a convex frame 63 is fixedly installed between the two guide frames 62, a drawing pen 66 is fixedly installed inside the convex frame 63, a writing board 67 is fixedly installed on one end surface of the mounting frame 61 near the drawing pen 66, a column 64 is embedded in the middle of the bottom end of the convex frame 63, and a ball 65 is embedded in the bottom end of the column 64. The ball 65 is attached to the top of the base 1, the top of the mounting frame 61 is rotatably connected to the limit bar 68, and the limit bar 68 is attached to the top of the writing board 67. The limit bar 68 is used to fix the writing board 67, which changes the difficulty of fixing the writing board 67. The top of the inner wall of the protrusion 63 is rotatably connected to a screw rod, and the bottom end of the screw rod and the outer side of the drawing pen 66 are attached to each other. The screw rod can squeeze and fix the drawing pen 66 to prevent the drawing pen 66 from shaking.

[0031] When the axis of the turntable 2 is offset, the bottom end of the ball 65 and the top end of the base 1 fit together and move downward under the action of gravity, so that the ball 65 is always in contact with the top end of the base 1, and when the ball 65 moves, it drives the boss 63 to move through the column 64. When the boss 63 moves, it drives the drawing pen 66 to move up and down on one end surface of the writing board 67. The drawing pen 66 that moves up and down marks a vertical line on the writing board 67. The maximum deviation of the turntable 2 during operation is observed by measuring the length of the vertical line. By using the electric measurement in the prior art and the manual measurement of the structure, a comparison can be made, thereby further improving the accuracy of the deviation angle of the turntable 2 during operation.

[0032] Working principle: During the actual use of the device, personnel rotate the screw rod 55, and when the screw rod 55 rotates, it drives the balance block 56 to move along the bottom end of the slider 54 and inside the connecting cover 53. At this time, under the action of multiple balance blocks 56, the axis of the turntable 2 remains vertical, and the center of gravity of the base 1 is changed. The balance block 56 is used to provide overall stability and support, and the low center of gravity design under the base 1 can effectively reduce high-frequency vibrations, thereby increasing the stability of the turntable 2 when rotating. Then, the object to be detected is installed inside the inner frame 4, and then the inner frame 4, the outer frame 3 and the turntable 2 are rotated, so that the object is subjected to three-axis rotation detection. When there is a deviation during the rotation of the turntable 2, the axis of the turntable 2 is changed. At the same time, the electric telescopic rod 59 is controlled to operate, and the electric telescopic rod 59 is controlled to operate. When the rod 59 is in operation, it drives one of the balancing blocks 56 to rise, and when the balancing block 56 rises, it drives the connecting rope 58 to move. At this time, the connecting rope 58 moves along the inside of the guide cover 57, and when the connecting rope 58 moves, the other balancing block 56 moves inside the connecting cover 53. When the turntable 2 has a deviation due to rotation at this time, the axis position of the turntable 2 is offset by adjusting the height between the two balancing blocks 56, so that the turntable 2 maintains balance, further increasing the stability of the objects inside the turntable 2 during the detection process, and effectively improving the dynamic balance performance of the turntable, which can not only improve the accuracy of the test data, but also reduce manual operations and improve work efficiency, thereby creating higher value for scientific research and engineering applications, and enabling it to adapt to more complex and demanding test environments;

[0033] Then, the writing board 67 and the drawing pen 66 are installed, and one end of the book core of the drawing pen 66 is attached to the white surface of the writing board 67. When the axis of the turntable 2 is offset, the bottom end of the ball 65 and the top end of the base 1 are attached to each other, and move downward under the action of gravity, so that the ball 65 is always attached to the top end of the base 1, and when the ball 65 moves, it drives the protrusion 63 to move through the column 64. When the protrusion 63 moves, it drives the drawing pen 66 to move up and down on one end surface of the writing board 67. The up and down moving drawing pen 66 marks a vertical line on the writing board 67. The maximum deviation of the turntable 2 during operation is observed by measuring the length of the vertical line. The electric measurement in the prior art and the manual measurement of the structure can be used to form a comparison, thereby further improving the accuracy of the deviation angle when the turntable 2 is running, thereby providing more comprehensive and accurate data for the operation of the turntable 2, and this combination provides richer and more reliable data support for subsequent data analysis and improvement.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
