Detailed implementation manner

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a tool bit storage device for a numerical control machine tool as shown in Figures 1-5 which includes a box body 101. A plurality of storage mechanisms are arranged inside the box body 101. The storage mechanism includes a horizontal plate 202. A plurality of communication holes 203 are spaced apart from each other at the top end of the horizontal plate 202. A rubber sleeve 204 is inserted through the inner wall of the communication hole 203. A fixing mechanism is arranged between the rubber sleeve 204 and the horizontal plate 202. The fixing mechanism includes a fixing bolt 502. An insertion hole 501 is opened at the top end of the rubber sleeve 204. The outer wall of the fixing bolt 502 is movably inserted through the inner wall of the insertion hole 501. A threaded hole 503 is opened at the top end of the horizontal plate 202. The outer wall of the fixing bolt 502 is threadedly connected to the inner wall of the threaded hole 503. The tool bit is directly inserted into the rubber sleeve 204 for storage. When the tool bit needs to be used, the tool bit can be taken out of the rubber sleeve 204. By passing the fixing bolt 502 through the insertion hole 501 and screwing it into the threaded hole 503, the rubber sleeve 204 is fixed to the horizontal plate 202, so that the rubber sleeve 204 can work stably, avoiding the rubber sleeve 204 being taken out of the communication hole 203 while the tool bit is taken out of the rubber sleeve 204, thereby improving the working stability of the rubber sleeve 204. Universal wheels can be arranged at the bottom end of the box body to facilitate the movement of the box body 101, and the mobility of the storage device can be improved;

[0025] In a preferred embodiment, a rotating mechanism is arranged inside the box body 101. The rotating mechanism is used to change the positions of a plurality of storage mechanisms. The rotating mechanism includes turntables 201 symmetrically and rotatably connected to the inner wall of the box body 101. A plurality of storage mechanisms are all rotatably arranged between the two turntables 201. A weight mechanism is arranged at the bottom end of the storage mechanism. A communication groove is opened at the top end of the box body 101. By rotating the turntables 201 inside the box body 101, a plurality of storage mechanisms can be driven to revolve inside the box body 101 until a group of storage mechanisms rotates to the highest position. At this time, its position is aligned with the communication groove, and the tool bit in this storage mechanism can be taken out and used at the top end of the box body 101, avoiding the inconvenience of bending down and squatting when using a multi-layer drawer type, and improving the convenience of storing and taking out the tool bit.

[0026] Among them, both sides of the horizontal plate 202 are fixedly connected with a first rotating shaft 301. A first rotating hole is provided on one side of the turntable 201. The outer wall of the first rotating shaft 301 is rotatably connected with the inner wall of the first rotating hole. By rotating the first rotating shaft 301 in the first rotating hole, the horizontal plate 202 can be rotated.

[0027] Among them, the counterweight mechanism includes a counterweight plate 401. The counterweight plates 401 are symmetrically and fixedly connected to the bottom end of the horizontal plate 202. Through the counterweight cooperation of the two counterweight plates 401, the center of gravity of the storage mechanism is lower than the rotation position of the horizontal plate 202. Thus, during the rotation of the turntable 201, the horizontal plate 202 can always maintain a horizontal state, that is, as Figure 2 shown. Thus, the storage mechanism rotated to the uppermost position can maintain horizontal, facilitating the taking of the tool head. At the same time, it also ensures that the tool head will not fall out of the storage mechanism during the rotation of the turntable 201, thereby improving the stability of the tool head storage.

[0028] Among them, one side of the turntable 201 is fixedly connected with a second rotating shaft 601. Second rotating holes are provided on both sides of the box body 101. The outer wall of the second rotating shaft 601 is rotatably connected with the inner wall of the second rotating hole. One end of one of the second rotating shafts 601 penetrates the inside of the second rotating hole and is fixedly connected with a worm gear 602. The outer wall of the worm gear 602 is meshed with a worm 603. By rotating the second rotating shaft 601 in the second rotating hole, the turntable 201 can be rotated in the box body 101. Through the meshing of the worm 603 and the worm gear 602, the rotation of the worm 603 can drive the rotation of the worm gear 602. The rotation of the worm gear 602 can drive the rotation of the turntable 201 under the connection of the second rotating shaft 601. And the lead angle of the worm 603 is smaller than the equivalent friction angle between the teeth of the worm gear 602. When the worm gear 602 and the worm 603 cooperate, only the worm 603 can rotate to drive the worm gear 602 to rotate, and reverse operation is impossible. Thus, as long as the worm 603 does not rotate, the storage mechanism can be stably located inside the box body 101, thereby improving the stability of the storage device during operation.

[0029] Among them, one side of the box body 101 is fixedly connected with a protective box 701. The worm gear 602 and the worm 603 are both arranged inside the protective box 701. One end of the worm 603 penetrates the inner wall of the protective box 701 and is fixedly connected with a rotating plate 702. A handle 703 is fixedly connected to the side of the front surface of the rotating plate 702. The protective box 701 can protect the worm 603 and the worm gear 602. And through the arrangement of the rotating plate 702 and the handle 703, the worm 603 can be rotated outside the protective box 701. By holding the rotating plate 702 and rotating the handle 703, the rotation force arm of the worm 603 is increased, making it more labor-saving to rotate the worm 603 and improving the convenience of the operation of the worm 603.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
