[0021] Example 1

[0022] Please see Figure 1-5An internal support type fixing frame for non-ferrous metal processing includes a working frame 1, an upper internal support component 2 and a lower internal support component 3. The upper internal support component 2 and the lower internal support component 3 are both connected to the working frame 1. The upper internal support component 2 is used to extend into the workpiece from the upper end of the workpiece to internally support and fix the workpiece, and the lower internal support component 3 is used to internally support and fix the workpiece from the lower end of the workpiece.

[0023] The upper inner support assembly 2 includes a height adjustment cylinder 201, a connecting cover 202, an upper drive cylinder 203, a drive plate 204, a mounting base 205, a first connecting rod 206, a second connecting rod 207, and an upper inner support plate 208. The height adjustment cylinder 201 is fixedly connected to the top surface of the working frame 1. The output end of the height adjustment cylinder 201 passes through the working frame 1 and is fixedly connected to the connecting cover 202. The upper drive cylinder 203 is fixedly connected to the inner top surface of the connecting cover 202. The output end of the upper drive cylinder 203 is fixedly connected to the drive plate 204. Several sets of mounting bases 205 are evenly distributed in a circumferential array on the outer wall of the connecting cover 202. The first connecting rod 206 is rotatably connected to the mounting base 205. Several sets of second connecting rods 207 are evenly distributed in a circumferential array on the drive plate 204. The other ends of the first connecting rod 206 and the second connecting rod 207 are rotatably connected to the upper inner support plate 208.

[0024] The upper inner support assembly 2 also includes an air pump 209, an air outlet 210, and an air hose 211. The air pump 209 is fixedly connected to the top surface of the working frame 1, and the air outlet of the air pump 209 is fixedly connected to the air hose 211. Several sets of evenly distributed air outlets 210 are opened on the upper inner support plate 208, and the other end of the air hose 211 is connected to the air outlet 210.

[0025] First, based on the workpiece's height, the height of the upper inner support assembly 2 is adjusted using the height adjustment cylinder 201, allowing the upper inner support plate 208 to smoothly extend into the workpiece from its upper end. Then, the upper drive cylinder 203 is activated, its output pushing the drive plate 204 downwards. Since the drive plate 204 is rotatably connected to the second connecting rod 207, and the other end of the second connecting rod 207 is rotatably connected to the upper inner support plate 208, the downward movement of the drive plate 204 causes the second connecting rod 207 to swing, thereby pushing the upper inner support plate 208 inwards, thus fixing the upper end of the workpiece with internal support. Simultaneously, the air pump 209 operates, delivering gas to the air outlet 210 on the upper inner support plate 208 via the air hose 211. The blown gas removes dust and impurities from the inner surface of the workpiece, ensuring machining accuracy.

[0026] Example 2

[0027] This embodiment adds the following improvements based on Embodiment 1: The lower inner support assembly 3 includes a drive turntable 301, a mounting cover 302, a fixed base 303, a lower drive cylinder 304, and a drive block 305. The mounting cover 302 and the fixed base 303 are fixedly connected to the bottom surface of the inner side of the working frame 1, and the drive turntable 301 is rotatably connected to it. The drive turntable 301 is rotatably disposed inside the mounting cover 302. The lower drive cylinder 304 is fixedly connected to the side of the fixed base 303, and the drive block 305 is fixedly connected to the side of the drive turntable 301. The drive block 305 passes through the mounting cover 302 and is rotatably connected to the output end of the lower drive cylinder 304.

[0028] The lower inner support assembly 3 also includes a sliding groove 306, a sliding block 307, a lower inner support plate 308, and a guide groove 309. The drive turntable 301 has several sets of sliding grooves 306 evenly distributed in a circumferential array. Each sliding groove 306 is slidably connected to a sliding block 307. The top surface of the mounting cover 302 has several sets of guide grooves 309 evenly distributed in a circumferential array. The lower inner support plate 308 is fixedly connected above the sliding block 307. The lower inner support plate 308 is slidably connected to the guide groove 309.

[0029] When the lower drive cylinder 304 is activated, its extension and retraction movement causes the drive block 305 to move. Since the drive block 305 is fixedly connected to the drive turntable 301, the drive turntable 301 rotates within the mounting cover 302. The drive turntable 301 has a sliding groove 306. A sliding block 307 within the sliding groove 306 is fixedly connected to the lower inner support plate 308, and the lower inner support plate 308 is slidably connected to the guide groove 309 on the surface of the mounting cover 302. Therefore, when the drive turntable 301 rotates, the sliding block 307 slides within the sliding groove 306, while the lower inner support plate 308 moves outward under the guidance of the guide groove 309 until it makes tight contact with the lower end of the workpiece, thus securing the lower end of the workpiece internally. When it is necessary to disassemble the workpiece, the lower drive cylinder 304 moves in the opposite direction, the drive turntable 301 rotates in the opposite direction, and the lower inner support plate 308 moves inward, disengaging from the workpiece.

[0030] Working principle

[0031] First, based on the workpiece's height, the height of the upper inner support assembly 2 is adjusted using the height adjustment cylinder 201, allowing the upper inner support plate 208 to smoothly extend into the workpiece from its upper end. Then, the upper drive cylinder 203 is activated, its output pushing the drive plate 204 downwards. Since the drive plate 204 is rotatably connected to the second connecting rod 207, and the other end of the second connecting rod 207 is rotatably connected to the upper inner support plate 208, the downward movement of the drive plate 204 causes the second connecting rod 207 to swing, thereby pushing the upper inner support plate 208 inwards, thus fixing the upper end of the workpiece with internal support. Simultaneously, the air pump 209 operates, delivering gas to the air outlet 210 on the upper inner support plate 208 via the air hose 211. The blown gas removes dust and impurities from the inner surface of the workpiece, ensuring machining accuracy.

[0032] When the lower drive cylinder 304 is activated, its extension and retraction movement causes the drive block 305 to move. Since the drive block 305 is fixedly connected to the drive turntable 301, the drive turntable 301 rotates within the mounting cover 302. The drive turntable 301 has a sliding groove 306. A sliding block 307 within the sliding groove 306 is fixedly connected to the lower inner support plate 308, and the lower inner support plate 308 is slidably connected to the guide groove 309 on the surface of the mounting cover 302. Therefore, when the drive turntable 301 rotates, the sliding block 307 slides within the sliding groove 306, while the lower inner support plate 308 moves outward under the guidance of the guide groove 309 until it makes tight contact with the lower end of the workpiece, thus securing the lower end of the workpiece internally. When it is necessary to disassemble the workpiece, the lower drive cylinder 304 moves in the opposite direction, the drive turntable 301 rotates in the opposite direction, and the lower inner support plate 308 moves inward, disengaging from the workpiece.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
