Description

Technical Field

[0001] The utility model relates to the technical field of aviation thin-walled parts production, in particular to an anti-deformation clamp for aviation thin-walled parts production. Background Art

[0002] Aviation thin-walled parts refer to structural parts with characteristics of lightness, high strength, and high rigidity, and are widely used in the aerospace field. These parts are usually composed of various thin plates and reinforcing ribs, and have outstanding advantages such as light weight, high strength, and beautiful appearance. In the aerospace field, the requirements for parts with light weight, high strength, and high reliability are extremely high, and thin-walled parts are the ideal choice to meet these requirements. They can greatly improve the load capacity and safety performance, so they have been widely used in many fields such as spacecraft parts, rocket parts, and aviation parts.

[0003] However, aviation thin-walled parts are prone to deformation during the processing, and their light and thin structure leads to weak rigidity, which is easily affected by external forces such as cutting force and clamping force. The existing fixtures only clamp the edges and corners of aviation thin-walled parts, resulting in a larger force-bearing area. Therefore, the cutting force will diffuse to the surrounding area. Therefore, during processing, it is always necessary to pay attention to the overall state of the aviation thin-walled parts, which greatly affects the processing efficiency. Therefore, in response to the above technical problems, an anti-deformation fixture for the production of aviation thin-walled parts is proposed herein. Utility Model Content

A placement groove 2 is provided on the upper side of the fixture body 1, and a thin-walled part template 3 is placed inside the placement groove 2. A support plate 4 is fixedly connected to the outside of the fixture body 1, and a mounting seat 5 is fixedly connected to the upper side of the support plate 4. A slide groove 6 is provided on the outside of the mounting seat 5, and a slide plate 8 is slidably connected to the inside of the slide groove 6, and the slide plate 8 is fixedly connected to the mounting plate 7. The lower side of the mounting plate 7 A spring 9 is fixedly connected, a pressure plate 10 is fixedly connected to the lower side of the spring 9, a pressing piece 11 is fixedly connected to the lower side of the pressure plate 10, and the pressing piece 11 is in contact with the thin-walled part template 3, a pull plate 12 is fixedly connected to the upper side of the pressure plate 10, and the pull plate 12 passes through the upper surface of the mounting plate 7, a slot 13 is provided on the lower side of the pull plate 12, a mounting slot 14 is provided on the upper side of the mounting plate 7, a rotating plate 16 is rotatably connected to the inside of the mounting slot 14, and the rotating plate 16 matches the slot 13.

[0025] The upper surface of the thin-walled part template 3 protrudes from the upper surface of the clamp body 1, which makes it easy to clamp and process the thin-walled part template 3.

[0026] The number of mounting plates 7 is two groups and they are arranged in a transverse manner. Two groups of mounting plates 7 can be provided with two groups of clamping belts that can be moved transversely, so as to clamp the processing area. The number of pressing pieces 11 is several groups and they are arranged in an array.

[0027] A rotating rod 15 is fixedly connected inside the installation groove 14 , and the rotating rod 15 is rotatably connected to the rotating plate 16 . The rotating plate 16 can be controlled to rotate by the rotating rod 15 to be inserted into the slot 13 .

[0028] A connecting plate 17 is fixedly connected to the lower side of the clamp body 1 , and a mounting hole 18 is provided on the lower side of the connecting plate 17 . The clamp can be easily installed through the connecting plate 17 and the mounting hole 18 .

[0030] The working principle of an anti-deformation clamp for the production of aviation thin-walled parts based on the embodiment is that before using this clamp, the pulling plate 12 can be pulled to drive the pressing plate 10 to lift the pressing piece 11, and at the same time compress the spring 9, and then the rotating plate 16 inside the installation groove 14 is rotated to align the position of the rotating plate 16 with the slot 13 on the lower side of the pulling plate 12, and then the pulling plate 12 is released to make the rotating plate 16 snap into the slot 13, and the retraction of the pressing piece 11 can be completed, so that the sliding plate 8 can slide in the sliding groove 6, so that the mounting plate 7 can be controlled to move horizontally, so that two sets of movable horizontal clamps can be set. The thin-walled part template 3 is then placed in the placement groove 2, and then the pull plate 12 is pulled to allow the rotating plate 16 to move out of the slot 13, and then the pull plate 12 is released, and the pressing piece 11 can be driven by the spring 9 to firmly support the thin-walled part template 3. By changing the position between the two sets of mounting plates 7, the processing area can be controlled to be located between the two sets of clamping belts, and the distance between the two sets of clamping belts can be changed to change the area where the cutting force is diffused, thereby avoiding the cutting force from diffusing to the outside. Therefore, there is no need to always pay attention to the working status of aviation thin-walled parts during processing, and the processing efficiency can be improved.
