DETAILED DESCRIPTION

[0017] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] Please refer to Figs. 1-2 The utility model provides a technical scheme:

[0019] In this technical scheme, a smart milling machine cutting head with a protection function includes a tool holder 1 and a milling cutter 2. The lower wall of the tool holder 1 is provided with a tool shank 3, which can be inserted into the rotating shaft of an external smart milling machine. The upper end of the tool holder 1 is provided with the milling cutter 2.

[0020] The upper wall of the tool holder 1 is provided with an annular groove 4, and the annular groove 4 is provided with a magnet 5. The outer wall of the milling cutter 2 is provided with a protection mechanism 6, which includes a connecting sleeve 61, a threaded hole 62, a screw rod 63, and a magnetic ring 64. The connecting sleeve 61 is connected to the outer wall of the milling cutter 2. The side wall of the connecting sleeve 61 is provided with a threaded hole 62, and the threaded hole 62 is provided with a screw rod 63. The screw rod 63 can be connected to the side wall of the milling cutter 2. The lower wall of the connecting sleeve 61 is provided with a magnetic ring 64, which can be connected to the magnet 5.

[0021] In this technical scheme, the milling cutter 2 is inserted into the seat body 11 through the cooperation of the snap spring 13 and the threaded sleeve 12 in the tool holder 1. Then, by rotating the threaded sleeve 12, the snap spring 13 can be tightened, thereby clamping and fixing the milling cutter 2.

[0022] When the milling cutter 2 is fixed, the magnetic ring 64 in the protection mechanism 6 can be connected to the magnet 5, thereby fixing the milling cutter 2 again.

[0023] When the milling cutter 2 needs to be replaced, the threaded sleeve 12 is loosened, the snap spring 13 is relaxed, and the milling cutter 2 is fixed. At this time, the worker needs to hold the milling cutter 2 tightly to avoid the milling cutter 2 from falling. If the worker is careless and does not hold the milling cutter 2 tightly, the milling cutter 2 will still be connected to the threaded sleeve 12 through the cooperation of the magnetic ring 64 and the magnet 5, thereby avoiding the situation that the milling cutter 2 falls and causes the blade to break.

[0024] In some technical schemes, the tool holder 1 includes a seat body 11, a threaded sleeve 12, and a snap spring 13. The inner cavity of the seat body 11 is conical. The outer side of the upper end of the seat body 11 is provided with external threads. The threaded sleeve 12 is rotatably installed on the outer side of the seat body 11. The snap spring 13 is inserted into the threaded sleeve 12. The cross-section of the snap spring 13 is conical. The milling cutter 2 is inserted into the snap spring 13.

[0025] In this technical scheme, the snap spring 13 is a commonly used tool fixing part in machine tools. Through the cooperation of the snap spring 13 and the seat body 11, the snap spring 13 can be tightened and loosened by rotating the threaded sleeve 13, thereby fixing and loosening the milling cutter 2.

[0026] In some technical solutions, the magnetic attraction ring 64 comprises a connecting rod 641, a limiting block 642 and a magnetic ring 643, the lower wall of the connecting sleeve 61 is provided with a sliding groove 7, the connecting rod 641 is slidingly installed in the sliding groove 7, one end of the connecting rod 641 located in the sliding groove 7 is provided with the limiting block 642, and the other end of the connecting rod 641 located outside the sliding groove 7 is provided with the magnetic ring 643, which can be attracted and connected with the magnet 5.

[0027] In some technical solutions, the outer side of the connecting rod 641 is sleeved with a rubber sleeve 8, which can be attached to the inner wall of the sliding groove 7.

[0028] In this technical solution, the rubber sleeve 8 can be attached to the inner wall of the sliding groove 7, so as to increase the friction between them.

[0029] In some technical solutions, the outer side wall of the screw rod 63 is sleeved with a sealing ring 9, which can be attached to the outer side wall of the connecting sleeve 61.

[0030] In this technical solution, when the milling cutter 2 is milling the workpiece, it will spray cooling liquid. In order to prevent the cooling liquid from entering the threaded hole 62, the sealing ring 9 is arranged to close the threaded hole 62, so as to avoid rust of the screw rod 63.

[0031] In some technical solutions, the side wall of the threaded sleeve 12 is provided with a clamping groove 10, and a plurality of clamping grooves 10 are evenly distributed on the side wall of the threaded sleeve 12.

[0032] In this technical solution, the clamping groove 10 is arranged, so that the threaded sleeve 12 can be conveniently rotated by an external wrench.

[0033] Working principle: first, insert the milling cutter 2 into the clamping spring 13 in the tool holder 1, then tighten the threaded sleeve 12, so that the clamping spring 13 locks the milling cutter 2, then pull the magnetic attraction ring 64, so that the magnetic attraction ring 64 is attracted to the magnet on the tool holder 1, and the milling cutter 2 is fixed again.

[0034] When the milling cutter 2 needs to be replaced, loosen the threaded sleeve 12, at this time the clamping spring 13 is relaxed, and the fixing of the milling cutter 2 is released, at this time the worker needs to hold the milling cutter 2 tightly with his hand to avoid the milling cutter 2 from falling, if the worker is careless and does not hold the milling cutter 2 tightly, at this time the milling cutter 2 is still attached to the threaded sleeve 12 under the cooperation of the magnetic attraction ring 64 and the magnet 5, so as to avoid the situation that the milling cutter 2 falls and causes the blade to break.
