Description

Technical Field

[0001] The utility model belongs to the field of machining fixtures for aviation parts, and particularly relates to a grinding tooling for a quick-release ring. Background Art

[0002] A quick-release ring is a ring-shaped aviation part with relatively large product size and high precision requirements for both end faces. During machining, a surface grinding process is required to grind the two end faces to meet the precision requirements. In the grinding process of general metal materials, an electromagnetic chuck is used to adsorb the metal material, and then the surface grinding process is carried out. However, the material of the quick-release ring is titanium alloy, which does not have magnetic properties and cannot be adsorbed and fixed by an electromagnetic chuck, so the surface grinding process cannot be directly carried out. In order to solve the technical problems existing in the surface grinding process of the quick-release ring, the utility model researches a tooling that can clamp the quick-release ring and carry out the surface grinding process. Content of the Utility Model

[0003] In order to solve the above problems, the utility model provides a grinding tooling for a quick-release ring, which clamps the quick-release ring and uses a magnetizable tooling to fix the quick-release ring on an electromagnetic chuck, simplifying the surface grinding process of the quick-release ring.

[0004] A grinding tooling for a quick-release ring includes a bottom plate and a baffle. The bottom plate is made of a magnetizable material so that the bottom plate can be magnetically adsorbed and fixed by an electromagnetic chuck. The baffle is installed on the upper end face of the bottom plate. A fixing groove is opened in the middle part of the baffle, and the shape of the fixing groove is consistent with the outer contour of the quick-release ring, allowing the quick-release ring to be embedded in the fixing groove. In order to fix the position of the quick-release ring, a gasket is installed on the bottom plate, and the gasket is located in the middle of the fixing groove. A movable pressing plate is arranged on the outer periphery of the gasket, and the inner ring of the quick-release ring is pressed and fixed by moving the pressing plate to make the end of the pressing plate press. In order to strengthen the fixing effect on the quick-release ring, screw holes leading to the fixing groove are opened on two opposite side faces of the baffle, and by inserting bolts into the screw holes, the quick-release ring can be fixed from the side.

[0005] As one of the connection methods of the pressing plate, a kidney-shaped hole is arranged in the middle of the pressing plate, and the pressing plate is installed on the gasket by using a bolt passing through the kidney-shaped hole. When the bolt is not tightened, the pressing plate can move through the kidney-shaped hole.

[0006] As the best choice of the pressing plate, the number of pressing plates is set to three, which can not only achieve a good fixing effect but also improve the fixing efficiency of the quick-release ring.

[0007] To facilitate the fixation of the stopper and the gasket on the bottom plate, 5 screw holes are provided on the bottom plate, with 1 located at the center of the bottom plate and the other 4 distributed around the perimeter of the bottom plate. The 4 screw holes around the perimeter of the bottom plate are used to fix the baffle. Four through holes are drilled in the baffle, and the positions of the four through holes correspond to the four screw holes around the perimeter of the bottom plate. By inserting bolts through the through holes in the baffle and into the screw holes in the bottom plate, the baffle can be fixed to the bottom plate. The screw hole at the center of the bottom is used to fix the gasket. A through hole is provided at the center of the gasket. By inserting a bolt through the through hole in the gasket and into the screw hole at the center of the bottom plate, the gasket can be fixed to the bottom plate.

[0008] The quick-release ring grinding tooling provided by the present utility model solves the problem that the quick-release ring cannot be fixed on the electromagnetic chuck, can completely fix the quick-release ring, ensures no shaking during the processing, improves the processing accuracy, and has a simple and fast usage method.

[0015] To further illustrate the concept of the present utility model, the following further elaborates on the detailed embodiments of the present utility model with reference to the drawings:

[0016] A quick-release ring grinding tooling includes a bottom plate 1 and a baffle 2. The bottom plate 1 is made of a magnetizable metal material such as iron or stainless steel. The bottom plate 1 is rectangular, and a total of 5 screw holes are drilled at the four corners and the center of the bottom plate 1. The baffle 2 has the same shape as the bottom plate 1. Through holes are drilled at the four corners of the baffle 2, and a fixing groove 3 is drilled in the middle of the baffle 2 according to the shape of the quick-release ring. Screw holes leading to the fixing groove 3 are drilled on two opposite sides of the baffle 2, as Figure 1 shown. The gasket 4 is a circular sheet structure. A through hole is drilled at the center of the gasket 4, and then three screw holes are drilled on the gasket 4 in a circumferential distribution. Three sheet materials are taken as the pressing plate 5, and a kidney-shaped hole 6 is drilled in the middle of the pressing plate 5. Then, bolts are passed through the kidney-shaped hole 6, asFigure 2 As shown, the pressing plate 5 is fixed to the three circumferential screw holes of the gasket 4.

[0017] When performing the surface grinding process of the quick-release ring, first pass the baffle 2 through the through holes around it, and use bolts to pass through the through holes and connect to the screw holes around the bottom plate 1. After tightening, the baffle 2 is completely fixed on the bottom plate 1. Then use bolts to pass through the through hole in the center of the gasket 4 and fix the gasket 4 above the screw hole in the center of the bottom plate 1. After the fixation is completed, place the quick-release ring into the fixing groove 3. First, screw two bolts into the screw holes on the side of the baffle 2, and continuously tighten the bolts so that the top of the bolts touches the quick-release ring to initially fix it from both sides of the quick-release ring. Then loosen the bolts on the pressing plate 5, move the pressing plate 5 to a suitable position, use the pressing plate 5 to press the quick-release ring from the inner ring of the quick-release ring, and then tighten the bolts to fix the position of the pressing plate 5. After all three pressing plates 5 are fixed in the above manner, the quick-release ring is completely fixed in the fixing groove 3, as Figure 3 , Figure 4 shown, and there will be no shaking, then the surface grinding process of the quick-release ring can be started.

[0018] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, there can be various changes and modifications. Any modification, equivalent replacement, improvement, etc. made using the present invention shall be included within the protection scope of the present invention.
