Description

Technical Field

[0001] This utility model relates to the field of aircraft metal parts, and in particular to a fastening device for processing aircraft metal parts. Background Technology

[0002] An existing patent (publication number: CN106181502A) discloses a fixture for irregular workpieces used in metal processing, including a fixture structure and an operation display. The fixture structure consists of two parts: a detection component and a clamping component. The detection component has detectors around its perimeter, and the clamping component has hydraulic cylinders at each of its four corners. One end of each miniature hydraulic cylinder is connected to an arc-shaped baffle, and two miniature hydraulic cylinders are located on one side of the arc-shaped baffle. One end of each hydraulic cylinder is connected to a fixed baffle. A first hydraulic-pneumatic box is located on one side of the operation display, and a second hydraulic-pneumatic box is located on one side of the first hydraulic-pneumatic box. A detection, analysis, and processing device is located on one side of the second hydraulic-pneumatic box. However, the fixed baffle of this device is a fixed structure and cannot rotate, preventing the device from clamping tapered tubular parts. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a fastening device for aircraft metal parts that can stably clamp metal parts of different diameters without requiring a separate fastening structure for a single workpiece specification. This structure can also be used to process and fasten conical cylindrical parts, thus expanding the processing range.

[0004] The objective of this utility model is achieved through the following technical solution: A fastening device for processing aircraft metal parts includes a circular base plate, a metal part, an arc-shaped clamping plate, a rotating clamping plate, a supporting vertical plate, a rotating shaft, a sliding pressure plate, a threaded rotating rod, and an arc-shaped clamping plate. The lower part of the supporting vertical plate is connected to the circular base plate, and the lower side of the rotating clamping plate is in contact with the supporting vertical plate. The supporting vertical plates are symmetrically arranged on both sides of the rotating clamping plate. The lower part of the rotating clamping plate is connected to the symmetrical supporting vertical plates through a rotating shaft. The lower part of the threaded rotating rod has a circular turntable, the lower surface of which is in contact with the circular base plate. The arc-shaped clamping plate has an arc-shaped groove, and the circular turntable is adapted to the arc-shaped groove. The circular turntable is inserted into the arc-shaped groove and rotates within the arc-shaped groove. Three arc-shaped clamping plates are evenly distributed on the axial side of the circular turntable, and the lower part of the arc-shaped clamping plate is connected to the circular base plate.

[0005] The arc-shaped clamp is connected to a set of clamp side plates. The upper side of the rotating clamp fits into the clamp side plates. The clamp side plates are symmetrically arranged at both ends of the upper part of the rotating clamp. The rotating clamp has a side positioning shaft. The side positioning shaft is symmetrically arranged on both sides of the rotating clamp. The side positioning shaft passes through the clamp side plates and rotates inside the clamp side plates.

[0006] The inner side of the arc-shaped clamping plate is in contact with the metal component. The three arc-shaped clamping plates are evenly distributed on the axial side of the metal component. The lower surface of the sliding pressure plate is in contact with the rotating clamping plate. The lower part of the vertical slide rod is connected to the circular base plate. The sliding pressure plate has a slide rod insertion hole. The vertical slide rod is adapted to the slide rod insertion hole. The vertical slide rod is inserted into the slide rod insertion hole and slides in the slide rod insertion hole. Beneficial effects

[0007] 1. In this utility model, the lower part of the supporting vertical plate is fixedly mounted on a circular base plate. The rotating clamping plate is connected to the symmetrical supporting vertical plates via a rotating shaft, allowing the supporting vertical plates to support the rotating clamping plate through the rotating shaft. Simultaneously, the rotating clamping plate is rotatable around the rotating shaft. This rotatable structure allows the tilt angle of the rotating clamping plate to be adjusted according to the diameter of the metal part during use, thus adapting the device to the processing and clamping of metal parts of different diameters. The side plates of the clamping plate are mounted and fixed to the outside of the arc-shaped clamping plate. The side positioning shaft of the rotating clamping plate is inserted into the side plate, allowing the upper part of the rotating clamping plate to support the arc-shaped clamping plate through the side positioning shaft without affecting the rotation of the arc-shaped clamping plate. The rotatable structure of the arc-shaped clamping plate ensures that the inner side of the arc-shaped clamping plate remains in contact with the outer side of the metal part even when tilted. The three arc-shaped clamping plates clamp the metal part from the outside, ensuring stable processing of the metal part. 2. In this utility model, a circular turntable is inserted into an arc-shaped slot, and the lower part of the arc-shaped clamping plate is fixedly installed on a circular base plate. By using three arc-shaped clamping plates distributed on the axial side of the circular turntable to limit its position, the lower surface of the circular turntable is ensured to be in contact with the circular base plate without affecting the rotation of the circular turntable. Three vertical sliding rods are installed and fixed on the circular base plate, and the vertical sliding rods pass through the sliding pressure plate. The three vertical sliding rods position the sliding pressure plate, keeping it axially fixed. A threaded rotating rod passes through the sliding pressure plate, and when the threaded rotating rod rotates, it drives the sliding pressure plate to move up and down. When the sliding pressure plate moves up and down, it applies pressure to the lower part of the three rotating clamping plates, causing the three rotating clamping plates to rotate centripetally, thereby clamping the metal parts with the three arc-shaped clamping plates. By using a rotatable clamping plate structure in conjunction with a rotating shaft support, the tilt angle of the clamping plate can be adjusted according to the diameter of the metal part. Combined with the rotating design of the arc-shaped clamping plate, the device can stably clamp metal parts of different diameters without the need to design a separate fastening structure for a single specification of workpiece. This structure can also be used to process and clamp conical cylindrical structures, expanding the processing range. Attached Figure Description

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A fastening device for processing aircraft metal parts includes a circular base plate 01, a metal part 02, an arc-shaped clamping plate 03, a rotating clamping plate 06, a supporting vertical plate 07, a rotating shaft 08, a sliding pressure plate 09, a threaded rotating rod 11, and an arc-shaped clamping plate 13. The lower part of the supporting vertical plate 07 is connected to the circular base plate 01 and is fixedly mounted on the circular base plate 01. The lower side of the rotating clamping plate 06 is in contact with the supporting vertical plate 07. The supporting vertical plates 07 are symmetrically arranged on both sides of the rotating clamping plate 06. The lower part of the rotating clamping plate 06 is connected to the symmetrical supporting vertical plates 07 through the rotating shaft 08, so that the supporting vertical plates 07 support the rotating clamping plate 06 through the rotating shaft 08. At the same time, the rotating clamping plate 06 is rotatable about the rotating shaft 08. The rotating clamping plate 06 is configured to be rotatable, and can be adjusted according to the diameter of the metal part 02 during use. The tilt angle of the rotating clamp 06 is adjusted to allow the device to be adapted to the processing and clamping of metal parts 02 of different diameters. The lower part of the threaded rotating rod 11 has a circular turntable 15, the lower surface of which is in contact with the circular base plate 01. The arc-shaped clamping plate 13 has an arc-shaped groove 14, which is adapted to the circular turntable 15. The circular turntable 15 is inserted into the arc-shaped groove 14 and rotates within it. The three arc-shaped clamping plates 13 are evenly distributed on the axial side of the circular turntable 15. The lower part of the arc-shaped clamping plate 13 is connected to the circular base plate 01 and is fixed on the circular base plate 01. By limiting the circular turntable 15 with the three arc-shaped clamping plates 13 distributed on the axial side of the circular turntable 15, the contact between the lower surface of the circular turntable 15 and the circular base plate 01 is ensured without affecting the rotation of the circular turntable 15.

[0013] Example 2: The curved clamp 03 of this utility model is connected to a set of clamp side plates 04. The clamp side plates 04 are installed and fixed on the outside of the curved clamp 03. The upper side of the rotating clamp 06 is in contact with the clamp side plates 04. The clamp side plates 04 are symmetrically arranged at both ends of the upper part of the rotating clamp 06. The rotating clamp 06 has a side positioning shaft 05 on its side. The side positioning shaft 05 is symmetrically arranged on both sides of the rotating clamp 06. The side positioning shaft 05 passes through the clamp side plates 04 and rotates within the clamp side plates 04.

[0014] Example 3: The inner side of the arc-shaped clamp 03 of this invention is in contact with the metal component 02. Three arc-shaped clamps 03 are evenly distributed on the axial side of the metal component 02. The side positioning shaft 05 on the side of the rotating clamp 06 is inserted into the side plate 04 of the clamp, allowing the upper part of the rotating clamp 06 to support the arc-shaped clamp 03 via the side positioning shaft 05 without affecting the rotation of the arc-shaped clamp 03. The arc-shaped clamp 03 is designed to be rotatable, ensuring that the inner side of the arc-shaped clamp 03 remains in contact with the outer side of the metal component 02 even when the rotating clamp 06 is tilted. The three arc-shaped clamps 03 are evenly distributed on the outer side of the metal component 02. The metal part 02 is clamped to ensure stable processing. The lower surface of the sliding pressure plate 09 is in contact with the rotating clamping plate 06. The lower part of the vertical slide rod 10 is connected to the circular base plate 01. The three vertical slide rods 10 are installed and fixed on the circular base plate 01. The sliding pressure plate 09 has a slide rod insertion hole 16. The vertical slide rod 10 is adapted to the slide rod insertion hole 16. The vertical slide rod 10 is inserted into the slide rod insertion hole 16 and slides within the slide rod insertion hole 16. The three vertical slide rods 10 position the sliding pressure plate 09, keeping the sliding pressure plate 09 axially fixed. Example 4: The threaded rotating rod 11 of this invention is connected to a rotating rod handle 12 on its upper outer side. The threaded rotating rod 11 passes through a sliding pressure plate 09 and rotates within the sliding pressure plate 09. When the threaded rotating rod 11 rotates, it drives the sliding pressure plate 09 to move up and down. This up-and-down movement of the sliding pressure plate 09 applies pressure to the lower parts of the three rotating clamping plates 06, causing the three rotating clamping plates 06 to rotate centripetally, thereby clamping the metal part 02 with the three arc-shaped clamping plates 03. Through the rotatable rotating clamping plate 06 structure and its cooperation with the rotating shaft 08 support shaft, the tilt angle of the rotating clamping plates 06 can be adjusted according to the diameter of the metal part 02. Combined with the rotational design of the arc-shaped clamping plates 03, the device can stably clamp metal parts 02 of different diameters, eliminating the need for a separate fastening structure for a single workpiece specification and expanding the processing range.

[0015] Example 5: The installation steps of this utility model are as follows: First, connect the lower part of the support vertical plate 07 to the circular base plate 01. Then, connect the lower part of the rotating clamp 06 to the symmetrical support vertical plate 07 through the rotating shaft 08. Insert the side positioning shaft 05 into the side plate 04 of the clamp. Connect the side plate 04 of the clamp to the arc-shaped clamp 03. Insert the circular turntable 15 into the arc-shaped slot 14. Connect the lower part of the arc-shaped clamp 13 to the circular base plate 01. Pass the threaded rotating rod 11 through the sliding pressure plate 09. Connect the rotating rod handle 12 to the outside of the threaded rotating rod 11. Pass the vertical slide rod 10 through the slide rod insertion hole 16 and connect it to the circular base plate 01.
