[0018] A machine tool spindle box protection device, such as Figures 1 to 3 As shown, it includes a machine tool body 1, a mounting chuck 2 is provided on the outside of the machine tool body 1, and a positioning clamp 3 for positioning the workpiece is provided on the mounting chuck 2. The surface of the machine tool body 1 is provided with two corresponding limit slots 11, and the limit slot 11 is an arc-shaped slot with a smooth inner wall. The surface of the machine tool body 1 is also fixed with two mounting bases 4 that are symmetrical to each other. The mounting bases 4 are located on the outside of both sides of the limit slot 11, and a protective plate 5 is installed in the limit slot 11. The protective plate 5 is an arc-shaped plate structure that is adapted to the inner shape of the limit slot 11. A docking seat 6 is fixedly installed on the wall of the side of the protective plate 5 close to the machine tool body 1, and positioning holes 7 for inserting mounting bolts are provided inside both ends of the docking seat 6. Grooves that are adapted to the size of the positioning holes 7 are provided on the inner wall of both ends of the limit slot 11 for bolts to pass through and lock.

Locking holes 9 are provided on the upper and lower surfaces of the interior of the connecting card seat 8. A connecting plug plate 10 is fixedly mounted on the surface of the mounting base 4 corresponding to one side of the protective plate 5. The interior of the connecting plug plate 10 is a hollow structure whose size is adapted to the interior of the locking hole 9. The mounting base 4 is inserted into the interior of the connecting card seat 8 and locked by bolts. After the protective plate 5 is installed, it can be rotated and swung on the outside of the mounting base 4;

[0020] When the rotating protective plate 5 is perpendicular to the surface of the machine tool body 1, the docking base 6 will be docked and inserted into the interior of the limit slot 11. At this time, the positioning holes 7 at both ends of the docking base 6 will correspond to the two side hole slots preset on the bottom surface of the limit slot 11. After fixing with bolts, the two positions are fixed, keeping the two protective plates 5 from loosening during workpiece processing, greatly improving the stability of the device.

[0021] An insertion cavity 12 is provided inside the side wall surfaces corresponding to each other of the two protective plates 5, and the insertion cavity 12 is connected to the front side wall surface of the protective plate 5.

When the magnetic plate 14 is pulled out, the adsorbed iron chips can be recovered, thereby improving the recovery efficiency of the iron chips.

[0022] The working principle of this utility model:

[0023] By providing a protective plate 5 for shielding, the two mounting bases 4 are positioned and installed on the surface of the machine tool body 1, and the docking card seat 6 is added to the bottom surface of the protective plate 5. After the connecting plug plate 10 is inserted into the inside of the connecting card seat 8 installed on the surface of the protective plate 5, the locking is completed by passing the bolt through the two locking holes 9. After locking, the protective plate 5 can be flipped on the outside of the mounting base 4. When the rotating protective plate 5 is perpendicular to the surface of the machine tool body 1, the docking card seat 6 will be docked and inserted into the inside of the limit slot 11. At this time, the positioning holes 7 at both ends of the docking card seat 6 will correspond to the two side hole slots preset on the bottom surface of the limit slot 11. After fixing with bolts, the two positions are fixed, keeping the two protective plates 5 from loosening during workpiece processing, greatly improving the stability of the device.

[0024] A magnetic plate 14 for absorbing debris is provided, and rubber strips are provided on both sides of the magnetic plate 14. After the magnetic plate 14 is fully inserted into the insertion cavity 12, the rubber strips at both ends of the magnetic plate 14 will be inserted into the corresponding limiting grooves 13, so that the magnetic plate 14 will not slide after being fully inserted into the insertion cavity 12. After the workpiece is fixed and clamped by the positioning clamp 3, iron chips generated during the processing of the workpiece will splash onto the inner wall surface of the protective plate 5, and the debris will be absorbed on the surface of the magnetic plate 14, reducing the difficulty of collecting the debris that falls. When the magnetic plate 14 is pulled out, the absorbed iron chips can be recovered, thereby improving the recovery efficiency of the iron chips.
