Description

Technical Field

[0001] The present invention relates to the field of mechanical automation, and more specifically, to an automated three-dimensional mechanical guide rail used for carrying a wind / flow velocity meter for measurement in wind tunnel and fluid experiments. Background Art

[0002] Wind tunnels are the most widely used tools in aerodynamic research and testing. Wind tunnels are widely used to study the basic laws of aerodynamics to verify and develop relevant theories. Research in aircraft design and wind resistance of structures in the field of modern civil engineering relies heavily on wind tunnels.

[0003] However, the wind tunnel must be calibrated according to the experimental requirements before use to ensure the accuracy of the experimental results. When calibrating the wind field, the number of points to be measured ranges from dozens to hundreds, depending on the accuracy requirements and the size of the wind tunnel. In addition, a large number of measurement points also need to be measured in some wind tunnel experiments. Therefore, an automated guide rail capable of three-dimensional movement is needed to carry a pulsating anemometer to measure each measurement point.

[0004] In order to measure the three-dimensional space points in the wind tunnel, most wind tunnel laboratories currently use a suspended three-dimensional mobile measurement frame. This three-dimensional mobile measurement frame is mainly composed of longitudinal guide rails, transverse guide rails and vertical columns with motors. The longitudinal guide rails are fixed to the laboratory ceiling with screws, the transverse guide rails are fixed to the longitudinal guide rails, the top of the vertical column is installed on the transverse guide rails, and the measuring instrument is installed on the vertical column to measure any point within the three-dimensional measurement range.

[0005] The current suspended three-dimensional mobile measurement frame can fully meet the measurement requirements for wind tunnels without structures, and can be used without further adjustment after installation. However, since it is bolted to the top plate of the wind tunnel as a whole, it is very inconvenient to disassemble, and the volume of the vertical column is too large. When it is necessary to measure any measuring point of the wind tunnel where a structure has been placed, it is very likely that the structure and the vertical column will overlap in their travel path, which will make it impossible to move to the corresponding measuring point. Summary of the invention

[0006] In order to meet the need to measure any measuring point in three-dimensional space in wind tunnel tests and to solve the defects of the existing common suspended three-dimensional moving measuring frames, the present invention proposes a three-dimensional automated mechanical guide rail, which can realize the measurement of any measuring point in three-dimensional space and will not be blocked by structures in the test area.

[0007] The technical solution of the present invention is:

[0008] An automated three-dimensional mechanical guide rail comprises a longitudinal base guide rail 1, a column 2, a crossbeam 3, a vertical guide rail 4, a transverse guide rail 7, a servo motor and a controller.

[0009] Two longitudinal base rails 1 are placed in parallel on the wind tunnel floor, and the ends of the two are connected to form a rectangular frame through an angle steel 27, and the four corners of the rectangular frame are fixed by aluminum profile angle pieces B25. The servo motor B24 is fixed to the end of the base steel plate of the longitudinal base rail 1 through the longitudinal motor seat 23; two longitudinal bearing seats 21 are fixed to the base steel plate of the longitudinal base rail 1 through bolts, and a longitudinal lead screw 20 is installed between the two longitudinal bearing seats 21. The longitudinal lead screw 20 is connected to the servo motor B24 through the longitudinal coupling 22 and rotates under the drive of the servo motor B24. Two longitudinal linear guide rails 19 parallel to each other are horizontally mounted on the base steel plate of the longitudinal base guide rail 1, respectively located on both sides of the longitudinal base guide rail 1; the longitudinal slider 17 is nested on the longitudinal linear guide rail 19 and moves along the longitudinal linear guide rail 19, and the top of the longitudinal slider 17 is fixed with a connecting block 18; the connecting block 18 is connected to the longitudinal lead screw 20, and when the longitudinal lead screw 20 rotates, the connecting block 18 moves along the longitudinal lead screw 20 and drives the longitudinal slider 17 to achieve longitudinal movement. The longitudinal slider 17 supports and limits the connecting block 18 and the structure above the connecting block 18.

[0010] The two columns 2 are respectively fixed vertically on the two connecting blocks 18 through the aluminum angle pieces A5; the crossbeam 3 is horizontally fixed between the two columns 2 through the aluminum angle pieces A5, and the installation height of the crossbeam 3 is adjusted by the set screws on the aluminum angle pieces A5. The crossbeam 3 is installed with a rack 10 and a transverse guide rail 7. The vertical guide rail 4 is installed with a gear 9, a transverse slider 6 and a servo motor A11. The three vertical guide rails 4 are connected to the transverse guide rail 7 on the crossbeam 3 through the transverse slider 6; the vertical guide rail 4 drives the gear 9 to rotate through the servo motor A11, and the lateral movement of the vertical guide rail 4 on the crossbeam 3 is realized through the interaction between the gear 9 and the rack 10.

[0011] Two vertical bearing seats 13 are fixed to the upper and lower parts of the vertical guide rail 4, respectively. A vertical lead screw 14 is installed between the two vertical bearing seats 13. The top of the vertical lead screw 14 is connected to the servo motor A11 through a vertical coupling 12. A clamping device 16 is installed at the bottom of the vertical guide rail 4 for clamping the measuring equipment. The vertical slider 15 is connected to the horizontal slider 6 through a connecting plate. The vertical slider 15 and the crossbeam 3 maintain a constant relative height. When the servo motor A11 is working, it drives the vertical lead screw 14 to rotate. Since the vertical slider 15 maintains an absolute height unchanged, the entire vertical guide rail 4 moves up and down relative to the vertical slider 15, realizing the vertical movement of the clamping device 16.

[0012] The controller is connected to the servo motor via a data line to control the joint action of the guide rail in the longitudinal, transverse and vertical directions, thereby realizing the movement of the clamped measuring device to any measuring point in the measuring space.

[0013] Beneficial effects of the present invention: the three-dimensional automated mechanical guide rail of the present invention has the ability to measure any measuring point in the space and is not affected by structures in the measuring area; the guide rail is easy to install, disassemble and move, and if the guide rail must be moved out of the wind tunnel or its position must be changed, all processes can be completed within one hour; and the controller and operating system equipped with the guide rail are simple and clear, which is easy for novices to learn and operate.

DETAILED DESCRIPTION

[0022] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and technical solutions.

[0023] An automated three-dimensional mechanical guide rail comprises a longitudinal base guide rail 1, a column 2, a crossbeam 3, a vertical guide rail 4, a transverse guide rail 7, a servo motor and a controller.

[0024] like Figure 1 , Figure 5 and Figure 7 As shown, two longitudinal base rails 1 are placed in parallel on the wind tunnel floor, and the ends of the two are connected to form a rectangular frame by an angle steel 27, and the four corners of the rectangular frame are fixed by aluminum profile angle pieces B25. The angle steel 27 has both fixing and aligning functions. The servo motor B24 is installed on the base steel plate end of the longitudinal base rail 1 through the longitudinal motor seat 23. Two longitudinal bearing seats 21 are fixed on the base steel plate of the longitudinal base rail 1 by bolts 26, and a longitudinal lead screw 20 is installed between the two longitudinal bearing seats 21. The longitudinal lead screw 20 is connected to the servo motor B24 through a longitudinal coupling 22 and rotates under the drive of the servo motor B24. Two longitudinal linear guides 19 parallel to each other are horizontally installed on the base steel plate of the longitudinal base rail 1, respectively located on both sides of the longitudinal base rail 1. The longitudinal slider 17 is nested on the longitudinal linear guide 19 and moves along the longitudinal linear guide 19, and the top of the longitudinal slider 17 is fixed to the bottom of the connecting block 18. The connecting block 18 and the weight of the upper part of the connecting block 18 are supported by the longitudinal linear guide rail 19 and the longitudinal slider 17. The connecting block 18 is connected to the longitudinal lead screw 20. When the longitudinal lead screw 20 rotates, the connecting block 18 moves along the longitudinal lead screw 20, and synchronously drives the longitudinal slider 17 to realize longitudinal movement.

[0025] The two columns 2 are connected to the connecting block 18 through the aluminum angle piece A5 with set screws, and the columns 2 are perpendicular to the longitudinal base rail 1. The crossbeam 3 is horizontally fixed between the two columns 2 through the aluminum angle piece A5, and the installation height of the crossbeam 3 is adjusted by the set screws on the aluminum angle piece A5. The crossbeam 3 is installed with a rack 10 and a transverse guide rail 7. The vertical guide rail 4 is installed with a gear 9, a transverse slider 6 and a servo motor A11. The three vertical guide rails 4 are connected to the transverse guide rail 7 on the crossbeam 3 through the transverse slider 6. The vertical guide rail 4 drives the gear 9 to rotate through the servo motor A11, and the transverse movement of the vertical guide rail 4 on the crossbeam 3 is realized through the interaction between the gear 9 and the rack 10.

[0026] The servo motor A11 is fixed on the top of the vertical guide rail 4; two vertical bearing seats 13 are fixed on the vertical guide rail 4, and a vertical lead screw 14 is installed between the two vertical bearing seats 13; the vertical lead screw 14 is connected to the servo motor A11 through a vertical coupling 12. A clamping device 16 is installed at the bottom of the vertical guide rail 4; the clamping device 16 is customized according to needs and is used to clamp the measuring equipment. The vertical slider 15 is connected to the horizontal slider 6 through a connecting plate, and the vertical slider 15 and the crossbeam 3 maintain a constant relative height; when the servo motor A11 is working, it drives the vertical lead screw 14 to rotate. Since the vertical slider 15 maintains an absolute height unchanged, the entire vertical guide rail 4 moves up and down relative to the vertical slider 15, thereby realizing the vertical movement of the clamping device 16.

[0027] The control system of the present invention is divided into manual control and automatic control: in manual mode, the guide rail base and the vertical guide rail of the three-dimensional guide rail are controlled by the forward / backward keys on the controller to perform longitudinal, transverse and vertical movements, and the coordinate value of the current guide rail is displayed on the display screen; in automatic mode, the pre-set measuring point number and the corresponding coordinate are input into the controller, and the guide rail can be controlled to move accurately to any measuring point. For measuring points whose coordinates are difficult to calculate in the actual model, or measuring points whose coordinates are inaccurate due to deviations in the model size, the guide rail is manually controlled to move to the measuring point, the coordinates of the measuring point displayed on the controller display screen are recorded, and the recorded coordinates are input into the controller, and the guide rail can be controlled to move to the measuring point in automatic mode.
