[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] The existing assembly platform has a fixed size, resulting in a limited platform area. The assembly process requires the use of a large number of tools, and assembly personnel need to frequently travel back and forth to retrieve these tools, which wastes time and reduces the assembly efficiency of aero engines.
[0023] In view of this, the present invention provides an adjustable angle assembly platform for aero-engine assembly. Through the cooperation between the horizontal plate, the placement plate, the extension plate, the slide rail and the pulley, the area of the placement plate is increased. This solves the problem that the existing assembly platform has a fixed size, resulting in a limited platform area. As a result, a large number of tools are required during the assembly process, and the assembly personnel need to frequently go back and forth to retrieve the tools, which is time-consuming and reduces the efficiency of aero-engine assembly.
[0024] Those skilled in the art will connect the electrical components and their compatible power supplies in this case using wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle below, where the electrical components are connected in the order of operation. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.
[0025] Example 1, by Figure 1-5 As can be seen, the adjustable angle assembly platform for aircraft engine assembly in this case includes a base plate 1, an electric telescopic rod 2 fixedly connected to the top of the base plate 1, a connecting plate 3 fixedly connected to the top of the electric telescopic rod 2, an empty box 6 fixedly connected to the top of the connecting plate 3, a horizontal plate 12 provided on the top of the empty box 6, a placement plate 13 fixedly connected to the top of the horizontal plate 12, an extension plate 14 inserted between the horizontal plate 12 and the placement plate 13, a slide rail 15 opened on the surface of the horizontal plate 12, a pulley 16 fixedly connected to the bottom of the extension plate 14, and the outer wall of the pulley 16 fitting against the inner wall of the slide rail 15.
[0026] In the specific implementation process, it is worth noting that the bottom of the base plate 1 is fixedly connected to a support leg, which supports the base plate 1. The top and bottom of the electric telescopic rod 2 can be connected to the connecting plate 3 and the base plate 1 by bolts. The electric telescopic rod 2 is a TOMUUDT model. The connection between the electric telescopic rod 2 and the external controller is an analog control connection. The controller outputs an analog signal, which is connected to the driver of the electric telescopic rod 2 through a shielded cable. A rotatable handle can be provided on the side wall of the extension plate 14 to facilitate the movement of the extension plate 14 by the operator. The operator starts the electric telescopic rod 2 through the controller, which drives the connecting plate 3 to move, and the connecting plate 3 drives the empty box 6 to move. The empty box 6 moves the placement plate 13 to adjust its height. After adjustment, the operator stops the electric telescopic rod 2 via the controller. To increase the area of the placement plate 13, the operator moves the extension plates 14 on both sides. The extension plates 14 move between the horizontal plate 12 and the placement plate 13. The extension plates 14 move the pulleys 16, which move in the slide rails 15. This reduces the friction between the extension plates 14 and the horizontal plate 12 and the placement plate 13. The horizontal plate 12 and the placement plate 13 can be connected by bolts. The operator moves the extension plates 14 out. After adjustment, the operator can place tools on the extension plates 14 to increase the area of the placement plate 13.
[0027] Furthermore, a housing 17 is fixedly connected to the bottom of the horizontal plate 12, and a curved rod 18 passes through the bottom of the housing 17 and is movably connected to the housing 17. A horizontal column 20 is fixedly connected to the top of the curved rod 18, and an insertion rod 21 is fixedly connected to the top of the horizontal column 20. The insertion rod 21 passes through the top of the housing 17 and is movably connected to the housing 17. Springs 19 are fixedly connected to the bottom of the horizontal column 20 and the bottom of the inner wall of the housing 17, respectively. The springs 19 are sleeved on the outer wall of the curved rod 18. An insertion hole 23 is opened at the bottom of the extension plate 14, and the outer wall of the insertion rod 21 is inserted into the inner wall of the insertion hole 23.
[0028] In the specific implementation process, it is worth noting that when the staff moves the extension plate 14, the staff first pulls the crank rod 18, which moves in the housing 17 and is limited. The crank rod 18 drives the horizontal plate 12 to move, and the horizontal plate 12 compresses the spring 19. The type of spring 19 can be selected according to the actual situation. The horizontal plate 12 drives the insertion rod 21 to move, and the insertion rod 21 moves in the housing 17. The insertion rod 21 leaves the insertion hole 23, releasing the fixation of the extension plate 14. The staff moves the extension plate 14 out. After that, the staff releases the crank rod 18. At this time, the spring 19 rebounds, and the spring force causes the insertion rod 21 to be inserted into the corresponding insertion hole 23, fixing the moved extension plate 14. When the extension plate 14 is used up, the staff repeats the above steps to move the extension plate 14 back into the horizontal plate 12 and the placement plate 13, thereby improving the stability of the extension plate 14.
[0029] Furthermore, mounting holes 22 are provided on the surface of the placement plate 13;
[0030] In the specific implementation process, it is worth noting that there are several mounting holes 22. The mounting holes 22 are threaded holes. When assembling the aero engine, the workers first fix the matching assembly fixture to the placement plate 13 with bolts, and then assemble the aero engine.
[0031] Furthermore, a sleeve 5 is fixedly connected to the surface of the base plate 1, and a column 4 is sleeved on the inner wall of the sleeve 5. The top of the column 4 is fixedly connected to the bottom of the connecting plate 3.
[0032] In the specific implementation process, it is worth noting that when the connecting plate 3 moves, the connecting plate 3 drives the column 4 to move, and the column 4 moves in the sleeve 5, thereby enhancing the stability of the placement plate 13 during the height adjustment process.
[0033] Example 2, by Figure 1 , 2 As can be seen from 5, the bottom of the inner wall of the empty box 6 is fixedly connected to the motor 7 by the motor sleeve, the output shaft of the motor 7 is fixedly connected to the reducer 8, the output end of the reducer 8 is fixedly connected to the rotating shaft 9, the outer wall of the rotating shaft 9 is rotatably connected to the inner wall of the empty box 6 through the bearing, and the top of the rotating shaft 9 is fixedly connected to the bottom of the horizontal plate 12.
[0034] In the specific implementation process, it is worth noting that the model of motor 7 is SGM7G, the model of reducer 8 is NEUGARTPLF, the connection method between motor 7 and controller is industrial Ethernet connection, the servo drive is equipped with Ethernet interface, and it is connected to the factory network through a switch. Reducer 8 can be connected to empty box 6 with bolts. There can be maintenance doors hinged on the front or back of empty box 6. The maintenance doors can be used to inspect motor 7 and reducer 8. Heat dissipation holes can be opened on both sides of empty box 6 to dissipate heat from motor 7 and reducer 8. When it is necessary to rotate the placement plate 13, the operator starts motor 7 through controller. Motor 7 drives reducer 8 to rotate. Reducer 8 drives shaft 9 to rotate. Shaft 9 drives horizontal plate 12 to rotate. The horizontal plate 12 rotates the placement plate 13. After the rotation is completed, the operator stops motor 7 through controller to adjust the horizontal angle of the assembly platform.
[0035] Furthermore, a groove 10 is provided on the top of the empty box 6, and a slider 11 is slidably engaged with the inner wall of the groove 10. The slider 11 is fixed to the bottom of the horizontal plate 12.
[0036] In the specific implementation process, it is worth noting that the slider 11 is arc-shaped and the groove 10 is annular. When the placement plate 13 rotates, the placement plate 13 drives the slider 11 to rotate. The slider 11 rotates in the groove 10, which restricts the vertical displacement and lateral offset of the placement plate 13 during the rotation process, ensuring the stability and accuracy of the rotation.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
