Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to an adjustable fixing device for processing aerospace components. Background Technology

[0002] In the production of aerospace equipment, clamping and fixing devices are typically used to hold components before processing. For example, a tooling fixture for inspecting aerospace components, disclosed in publication number CN221792386U, includes a base and a controller. The base has a liftable placement platform, and multiple electric rotary cylinders are arranged around the platform. The rotation shaft of each rotary cylinder is connected to a cylinder seat, which is equipped with an electric telescopic cylinder. The floating joint of the telescopic cylinder has a mechanical gripper. When fixing components, this device requires placing the component on the base. However, when processing cylindrical components where the axial direction needs to be horizontal, although the corresponding mechanical grippers can be adjusted by the electric rotary cylinders, the distance between the grippers and the base necessitates the operator holding the component until it is clamped. During this process, the operator must constantly adjust the position of the component, making operation inconvenient.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0019] Please see Figure 1-3 In order to solve the problem that some fixed clamping devices require operators to hold the aircraft parts by hand until the aircraft parts are clamped, and the operators need to constantly adjust the position of the aircraft parts during this process, which is inconvenient, this technical solution is designed. The detailed technical solution is as follows;

[0020] An adjustable fixing device for processing aerospace components includes a base 1, on which a plurality of slide grooves 2 are arranged in a circular array. Each slide groove 2 is provided with a screw driver, and each screw driver is provided with an electric turntable 3. The electric turntable 3 is provided with a clamping structure.

[0021] It should be noted that the equipment is fixed at the target position by the base 1 and connected to the power supply, control system and pneumatic power system. Since this is existing technology, it will not be described in detail here. The electric turntable 3 and the clamping structure can move along the direction of the slide 2 through the spiral drive.

[0022] Specifically, the clamping structure includes a base plate 4, which is movably attached to the upper wall of the base 1. A bottom groove seat 5 is provided on the upper wall of the base plate 4. The upper wall of the bottom groove seat 5 has a V-shaped structure. A first motor 6 is installed on the inner wall of the bottom groove seat 5. The drive end of the first motor 6 is movably inserted into the side wall of the bottom groove seat 5. A pressure frame 7 is installed on the drive end of the first motor 6. A cylinder 8 is installed on the base plate 4. A pressure block 9 is installed on the telescopic end of the cylinder 8. The lower wall of the pressure block 9 has an inverted V-shaped structure.

[0023] It should be noted that when processing cylindrical aerospace parts, and the cylindrical parts need to be placed horizontally along their axis, the cylindrical parts are placed on the upper walls of the two corresponding bottom slot seats 5. The distance between the two corresponding bottom slot seats 5 can be adjusted by the operation of the screw drive. If the length of the cylindrical parts is small, the electric turntable 3 can also be used to rotate the pressure frame 7 on the bottom slot seat 5 to the outside of the equipment, so that the two corresponding bottom slot seats 5 can be closer together, expanding the range of applicable parts sizes. The cylinder 8 is contracted to press the lower wall of the pressure block 9 onto the cylindrical aerospace parts, thereby clamping the cylindrical aerospace parts. This eliminates the need for operators to lift the aerospace parts, making it easier to fix the aerospace parts.

[0024] When it is necessary to use the clamping frame 7 to hold the aircraft parts, place the aircraft parts in the center of the base 1. The electric turntable 3 can be used to make the clamping frame 7 face the center of the equipment. The screw drive can be used to make the clamping frame 7 close to the aircraft parts until the aircraft parts are clamped and fixed. At the same time, the first motor 6 can be used to make the clamping frame 7 rotate and adjust the angle of the clamping frame 7 to match the aircraft parts of different shapes.

[0025] Specifically, the screw drive includes a second motor 10, which is mounted on the inner wall of the slide 2. A lead screw 11 is mounted on the drive end of the second motor 10. One end of the lead screw 11 is movably inserted into the inner wall of the slide 2. A movable block 12 is movably mounted on the lead screw 11 through a thread. The movable block 12 is movably attached to the inner wall of the slide 2. An electric turntable 3 is mounted on the movable block 12.

[0026] It should be noted that the second motor 10 causes the lead screw 11 to rotate. The lead screw 11 is connected to the moving block 12 by a thread, and the slide groove 2 limits the moving block 12. Therefore, the moving block 12 moves along the axial direction of the lead screw 11, which drives the electric turntable 3 on it and the clamping structure on the electric turntable 3 to move.

[0027] During the clamping process, the positioning information of cylinder 8 and moving block 12 can be generated by setting various sensors. Since this is existing technology, it will not be described in detail here.

[0028] Preferably, and further still, the cross-sectional shape of the groove 2 is a convex structure;

[0029] As a preferred and further option, the upper wall of the bottom groove seat 5 is provided with multiple guide rods 13, which are movably inserted into the lower wall of the pressure block 9 to protect the telescopic end of the cylinder 8.

[0030] As a preferred and further option, a stabilizing frame 14 is provided between the first motor 6 and the bottom groove 5 for fixed connection between the first motor 6 and the bottom groove 5.

[0031] Preferably, there are at least two cylinders 8, located on both sides of the bottom groove seat 5, to ensure the balance of the movement of the pressure block.

[0032] 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.
