DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The role of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a grinding debris tooling for thin-walled parts, including a fixing plate 1. The cross-section of the fixing plate 1 is convex for connecting with the three-jaw chuck of the processing equipment. A thin-walled part 4 with a T-shaped cross-section is placed on one side of the fixing plate 1. An operating screw 2 is threadedly connected inside the fixing plate 1. A fixing cylinder 9 is fixedly connected to the side of the fixing plate 1 away from the operating screw 2. A sliding rod 6 is slidably connected to the inner wall of the fixing cylinder 9. The surface of the sliding rod 6 is slidably connected to the fixing plate 1. One end of the operating screw 2 located inside the fixing plate 1 is rotatably connected to one end of the sliding rod 6 located inside the fixing plate 1. Thus, the sliding rod 6 can be driven to slide in the fixing plate 1 through the operating screw 2, and the position of the sliding rod 6 can be fixed by the self-locking property of the threaded connection, thereby ensuring the stability of the device during use.

[0021] Further, the surface of the sliding rod 6 is rotatably connected with first connecting rods 11 arranged at equal circumferential intervals. The surface of the fixed cylinder 9 is rotatably connected with second connecting rods 12 arranged at equal circumferential intervals. The first connecting rods 11 and the second connecting rods 12 are rotatably connected to each other. The first connecting rods 11 and the second connecting rods 12 are arranged in a relatively inclined manner. Inner support plates 10 are arranged on the outer sides of the sliding rod 6 and the fixed cylinder 9 at equal circumferential intervals. The inner support plates 10 are arc-shaped, so that the inner support plates 10 can be more closely attached to the inner wall of the thin-walled part 4, improving the fixing effect of the device on the thin-walled part 4. One end of the first connecting rod 11 away from the sliding rod 6 is rotatably connected to the surface of the inner support plate 10. One end of the second connecting rod 12 away from the fixed cylinder 9 is slidably connected to the inside of the inner support plate 10. A set of the sliding rod 6 and the fixed cylinder 9 is also arranged at one end of the sliding rod 6 away from the fixed disk 1. A first thread groove 15 is formed on the surface of the sliding rod 6 away from the fixed disk 1. A connecting bolt 7 is fixedly connected to the end of the sliding rod 6 away from the fixed disk 1 on the fixed disk 1. The surface of the connecting bolt 7 is threadedly connected to the inner wall of the first thread groove 15. Further, through the arrangement of the first thread groove 15 and the connecting bolt 7, the two sliding rods 6 can be connected. A connecting disk 8 is rotatably connected to the surface of the fixed cylinder 9 on the fixed disk 1. A connecting disk 8 is also rotatably connected to the surface of the fixed cylinder 9 away from the fixed disk 1. A connecting screw 14 passing through the surface of the connecting disk 8 is slidably connected to the inside of the two connecting disks 8. A number of nuts 13 are threadedly connected to the surface of the connecting screw 14, and every two nuts 13 are distributed on both sides of the connecting disk 8. Further, through the arrangement of the nuts 13, the connecting screw 14 and the connecting disk 8 can be connected to each other, avoiding the situation that the connecting screw 14 and the connecting disk 8 move relative to each other, ensuring the stability of the device during use. At the same time, the arrangement of the connecting screw 14 can connect the two connecting disks 8 to each other, and further can connect the two fixed cylinders 9 to each other, thus ensuring that the two fixed cylinders 9 can move synchronously.

[0022] Further, an outer support cylinder 3 is arranged on one side of the fixed disk 1. The inner wall of the outer support cylinder 3 is also convex. One end of the outer support cylinder 3 close to the fixed disk 1 is fixedly connected with a threaded sleeve 5. The surface of the threaded sleeve 5 is threadedly connected to the inside of the fixed disk 1. A threaded ring groove 16 is formed at one end of the outer support cylinder 3 away from the fixed disk 1. Further, through the arrangement of the threaded ring groove 16, the other outer support cylinders 3 can be connected to the outer support cylinder 3 on the fixed disk 1.

[0023] Specifically, when grinding the inner wall of the thin-walled part 4, the staff can first connect several outer support cylinders 3 together according to the length of the thin-walled part 4, that is, screw the threaded sleeve 5 on a slide rod 6 into the threaded annular groove 16 of another outer support cylinder 3. Then, the thin-walled part 4 can be placed into the outer support cylinder 3. Subsequently, connect the outer support cylinder 3 at the first end to the fixed disk 1, that is, screw the threaded sleeve 5 at the first end into the fixed disk 1. Thus, as the threaded sleeve 5 is screwed in, the inner wall of the outer support cylinder 3 pushes against the protrusion of the thin-walled part 4, squeezing the thin-walled part 4 against the fixed disk 1. Then, the staff can grind the inner wall of the thin-walled part 4 by operating the equipment.

[0024] When grinding the outer surface of the thin-walled part 4, first, according to the overall length of the thin-walled part 4, connect several groups of fixed cylinders 9 and slide rods 6 to the fixed disk 1. Then, the staff can rotate the operating screw rod 2, which drives the slide rod 6 to slide in the [unspecified part], thereby driving the first connecting rod 11 and the second connecting rod 12 to rotate relative to each other. At the same time, the second connecting rod 12 slides on the inner support plate 10. With the relative rotation of the first connecting rod 11 and the second connecting rod 12, the first connecting rod 11 and the second connecting rod 12 gradually change from an inclined state to a horizontal state, thus pushing the inner support plate 10 outwards and gradually fitting it against the inner wall of the thin-walled part 4 to support the inner wall of the thin-walled part 4, thereby fixing the thin-walled part 4. Then, the staff can grind the outer surface of the thin-walled part 4. During the implementation of the device, it can support the inner and outer surfaces of the thin-walled part 4 respectively, so that when the thin-walled part 4 is being ground, the inner and outer surfaces of the thin-walled part 4 do not bulge or cave in. This avoids the situation where the thin-walled part 4 is prone to deformation during the grinding process due to its thin thickness, thereby improving the processing quality of the thin-walled part 4 and the usage effect of the device, which is worthy of promotion.

[0025] Working principle: When grinding the inner wall of the thin-walled part 4, the staff can first connect several outer support cylinders 3 together according to the length of the thin-walled part 4, that is, screw the threaded sleeve 5 on a slide rod 6 into the threaded annular groove 16 of another outer support cylinder 3. Then, the thin-walled part 4 can be placed into the outer support cylinder 3. Subsequently, connect the outer support cylinder 3 at the first end to the fixed disk 1, that is, screw the threaded sleeve 5 at the first end into the fixed disk 1. Thus, as the threaded sleeve 5 is screwed in, the inner wall of the outer support cylinder 3 pushes against the protrusion of the thin-walled part 4, squeezing the thin-walled part 4 against the fixed disk 1. Then, the staff can grind the inner wall of the thin-walled part 4 by operating the equipment.

[0026] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
