[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The present invention operates through a cylinder to push the sliding plate upward. The upward-moving sliding plate will move relative to the top frame. As the sliding plate moves upward, it drives the push plate upward. The push plate squeezes the limiting plate, and through the rotation of the plate shaft, the limiting plate moves toward the side away from the sliding plate, driving the movable claw to move closer to the center of the fixing base, for clamping the end wall of the high-speed spindle placed in the central area of the fixing base, achieving the purpose of clamping and limiting the spindle.

[0016] 2. The present invention uses the fixing base to support the core base, and the core base is used to socket the high-speed spindle. The bottom of the core base is solid and the bottom of the fixing base is hollow. When the fixing base and the core base are clamped, the solid bottom of the core base can directly support the end of the high-speed spindle. After the fixing base and the core base are disassembled, the hollow area of the fixing base can be used to thread through the high-speed spindle. Through the inner ring made of sponge material, the end wall of the high-speed spindle is wiped, simply cleaning the spindle, and at the same time facilitating the downward movement of the upper region of the spindle.

[0017] 3. The present invention uses the plate shaft to move the four movable claws closer to the fixing base to clamp the spindle placed in the area of the fixing base. The inclined end wall of the limiting plate is used to enable the limiting plate and the movable claw to rotate around the plate shaft when the limiting plate is pushed by the upward-moving push plate, causing the movable claw to approach the fixing base and the limiting plate to move away from the fixing base.

[0018] 4. The inner core and the cotton core of the present invention are both made of sponge material and are used to absorb water droplets. When there is moisture or water droplets on the end wall of the spindle, the inner core and the cotton core absorb the moisture. The middle cavity of the base can be filled with dry powder. The middle cavity of the base is connected to the cotton core, and the dry powder is used to further dry the cotton core, improving the drying performance, simply protecting the end wall of the spindle from moisture and preventing slipping due to moisture. The guide base and the cotton core are clamped to the side of the movable claw through the guide opening. After disassembling the guide base and the cotton core, the dry powder in the guide base and the cotton core can be replaced and dried. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The bracket 1 is fixedly connected to both the cylinder 2 and the cross plate 3, and the cross plate 3 is fixedly connected to the top frame 4. The cylinder 2 is in transmission with the sliding plate 5, and the top frame 4 is movably connected to the sliding plate 5 through the through hole 7. The sliding plate 5 is fixedly connected to the push plates 6. At the same time, the storage dishes 9 are symmetrically distributed about the center of the sliding plate 5. By operating the cylinder 2, the sliding plate 5 is pushed to move upward. The upward moving sliding plate 5 will move relative to the top frame 4. When the sliding plate 5 moves upward, it drives the push plates 6 to move upward. The push plates 6 squeeze the limiting plate 22 and rotate through the plate shaft 20, so that the limiting plate 22 moves toward the side away from the sliding plate 5, driving the movable claw 21 to move closer to the center of the fixing seat 11, for clamping the end wall of the high-speed spindle placed in the central area of the fixing seat 11, achieving the purpose of clamping and limiting the spindle. At the same time, the dish cavity 10 of the storage dish 9 is used to collect the chips generated during machining, facilitating the centralized treatment of the chips;

[0030] The top frame 4 and the fixing base 11 are fixedly connected to each other, and the fixing base 11 and the base bottom block 14 are fixedly connected to each other. Moreover, the base bottom block 14 and the inner ring 15 are adhesively connected. The fixing base 11 is snap-connected to the core base 16 through the seat cavity 12, the seat groove 13, and the core groove 17. And the vertical central axis of the core base 16 coincides with the vertical central axis of the fixing base 11. The fixing base 11 is used to support the core base 16, and the core base 16 is used to sleeve the high-speed spindle. The bottom of the core base 16 is solid, and the bottom of the fixing base 11 is hollow. When the fixing base 11 and the core base 16 are snap-connected, the solid bottom of the core base 16 can be used to directly support the end of the high-speed spindle. After the fixing base 11 and the core base 16 are disassembled, the hollow area of the fixing base 11 can pass through the high-speed spindle. Through the inner ring 15 made of sponge material, the end wall of the high-speed spindle is wiped, simply cleaning the spindle, and at the same time facilitating the downward movement of the upper region of the spindle;

[0031] The fixing base 11 and the support plate 19 are fixedly connected to each other, and the support plates 19 are annularly distributed about the center of the fixing base 11. The support plate 19 and the movable claw 21 form a rotating structure through the plate shaft 20, and the movable claw 21 and the limiting plate 22 are fixedly connected to each other. Moreover, the end wall of the side of the limiting plate 22 close to the fixing base 11 is inclined. Through the plate shaft 20, the four movable claws 21 move closer to the fixing base 11 to clamp the spindle placed in the area of the fixing base 11. And the inclined end wall of the limiting plate 22 is used to make the limiting plate 22 and the movable claw 21 rotate around the plate shaft 20 when the limiting plate 22 is pushed by the upward moving push plate 6, so that the movable claw 21 approaches the fixing base 11 and the limiting plate 22 moves away from the fixing base 11;

[0032] The movable claw 21 and the inner core 23 are adhesively connected to each other, and the movable claw 21 is snap-connected to the guide seat 25 and the cotton core 27 through the guide port 24. Since both the inner core 23 and the cotton core 27 are made of sponge material, they are used to absorb water droplets. When there is moisture or water droplets on the end wall of the spindle, the moisture is absorbed by the inner core 23 and the cotton core 27. And the middle cavity 26 of the seat can be filled with a drying powder. The middle cavity 26 of the seat is connected to the cotton core 27. The drying powder is used to further dry the cotton core 27 and improve the drying performance, simply providing moisture-proof protection for the end wall of the spindle and preventing slipping due to moisture. And the guide seat 25 and the cotton core 27 are snap-connected to the side of the end of the movable claw 21 through the guide port 24. After the guide seat 25 and the cotton core 27 are disassembled, the drying powder in the guide seat 25 and the cotton core 27 can be replaced and dried.

[0033] In summary, when the clamping tooling for high-speed spindle machining is in use, the cylinder 2 operates to push the slide plate 5 upward. The upward-moving slide plate 5 will move relative to the top frame 4. As the slide plate 5 moves upward, it drives the push plate 6 to move upward. The push plate 6 squeezes the limit plate 22, and through the rotation of the plate shaft 20, the limit plate 22 moves toward the side away from the slide plate 5, driving the movable claw 21 to move closer to the center of the fixed seat 11 for clamping the end wall of the high-speed spindle placed in the central area of the fixed seat 11, achieving the purpose of clamping and limiting the spindle. At the same time, the cavity 10 of the storage dish 9 is used to collect the debris generated during machining, facilitating the centralized treatment of the debris. The fixed seat 11 is used to support the core seat 16, and the core seat 16 is used to sleeve the high-speed spindle. The bottom of the core seat 16 is solid and the bottom of the fixed seat 11 is hollow. When the fixed seat 11 and the core seat 16 are clamped, the solid bottom of the core seat 16 can directly support the end of the high-speed spindle. After the fixed seat 11 and the core seat 16 are disassembled, the hollow area of the fixed seat 11 can pass through the high-speed spindle. Through the inner ring 15 made of sponge material, the end wall of the high-speed spindle is wiped, simply cleaning the spindle, and at the same time facilitating the downward movement of the upper region of the spindle. Through the plate shaft 20, the four movable claws 21 move closer to the fixed seat 11 to clamp the spindle placed in the area of the fixed seat 11. The inclined end wall of the limit plate 22 is used to enable the limit plate 22 and the movable claw 21 to rotate around the plate shaft 20 when the limit plate 22 is pushed by the upward-moving push plate 6, so that the movable claw 21 moves closer to the fixed seat 11 and the limit plate 22 moves away from the fixed seat 11. Since both the inner core 23 and the cotton core 27 are made of sponge material and are used to absorb water droplets. When there are moisture and water droplets on the end wall of the spindle, the moisture is absorbed through the inner core 23 and the cotton core 27. The middle cavity 26 of the seat can be filled with a drying powder, and the middle cavity 26 is connected to the cotton core 27. The drying powder is used to further dry the cotton core 27, improving the drying performance, simply protecting the end wall of the spindle from moisture and preventing slipping due to moisture. The guide seat 25 and the cotton core 27 are clamped to the side of the movable claw 21 through the guide port 24. After disassembling the guide seat 25 and the cotton core 27, the drying powder in the guide seat 25 and the cotton core 27 can be replaced and dried.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
