[0026] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this application, unless otherwise stated, "multiple" means two or more.

[0028] according to Figure 1 The diagram shown is a structural schematic of a material box provided in this application. The top of the material box 5 includes multiple slots for placing cutting tools; one side of the material box 5 has a positioning hole 6; the material box 5 also has an identification code 7.

[0029] Furthermore, the material box provided in this embodiment is applied to an automatic tool preparation and retraction machine. The material box 5 with identification code 7 is stored in the rack assembly of the tool preparation machine. Then, the clamping device identifies the drill bit model and storage location according to the identification code 7 of each material box 5, and then clamps the drill bit stored in the rack assembly according to the tool preparation requirements to complete the tool preparation process.

[0030] according to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this is a positioning and clamping mechanism for a material box provided in an embodiment of this application. The positioning and clamping mechanism is used to clamp the material box 5 and includes a positioning plate 1, a fixing plate, a longitudinal positioning frame 2, and a driving device 4.

[0031] The positioning plate 1 is fixedly connected to the bottom fixed plate via a connector. A longitudinal positioning frame, a transverse positioning frame, and a driving device are all disposed between the positioning plate and the fixed plate. The positioning plate 1 can be provided with multiple material box storage positions 11, each for placing a material box 5. Each material box storage position 11 has a first positioning groove 12 on its side. The longitudinal positioning frame 2 includes a first positioning element 21 and a longitudinal fixing beam 22. One end of the first positioning element 21 passes through the first positioning groove 12 and reciprocates within the first positioning groove 12 in a first direction under the drive of the longitudinal driving device 42 to abut against the first positioning groove 12. The end of the first positioning element 21 away from the first positioning groove 12 is fixedly connected to the longitudinal fixing beam 22, and one end of the longitudinal fixing beam 22 is fixedly connected to the output end of the longitudinal driving device 42.

[0032] Furthermore, the end of the second positioning member 31 away from the second positioning groove 13 is fixedly connected to the longitudinal fixing beam 22, and one end of the longitudinal fixing beam 22 is fixedly connected to the output end of the longitudinal driving device 42. A plurality of the first positioning members 21 are fixedly connected to the end of the longitudinal fixing beam 22 away from the longitudinal driving device 42. The plurality of first positioning members 21 are evenly distributed at intervals, and a single longitudinal driving device 42 can simultaneously drive the plurality of first positioning members 21 on the longitudinal fixing beam 22 connected to it to reciprocate along the first direction.

[0033] Preferred, according to Figure 4 , Figure 5 As shown, the first positioning member 21 includes a positioning pin structure 23. The positioning pin structure 23 is used to cooperate with the positioning hole 6 of the material box 5 to achieve clamping and positioning of the material box. The first positioning member 21 positions one side of the material box 5 through the positioning pin structure 23, thereby further improving the positioning accuracy.

[0034] Optionally, the side of the material box storage position 11 is also provided with a second positioning groove 13, and the positioning clamping mechanism further includes a transverse positioning frame 3. The transverse positioning frame 3 includes a second positioning element 31, and the driving device 4 further includes a transverse driving device 41. One end of the second positioning element 31 passes through the second positioning groove 13 and moves reciprocally in the second positioning groove 13 along the second direction and abuts against the material box 5 by being driven by the transverse driving device 41. The second positioning element 31 includes an elastic element 33, and the first direction is perpendicular to the second direction.

[0035] Preferred, according to Figure 4 , Figure 5 As shown, one end of the second positioning member 31 that abuts against the second positioning groove 13 is also connected to an elastic member 33. The elastic member 33 is elastically connected to the second positioning member 31 and is used to connect the material box 5. The elastic positioning member achieves a leeway connection with the material box 5, thereby enabling the clamping and positioning of material boxes with different precision and size.

[0036] Preferably, the first positioning member 21 and the second positioning member 31 can simultaneously or independently perform the clamping and releasing actions of the material box 5. The first positioning member 21 and the second positioning member 31 can independently or simultaneously perform the clamping and releasing actions through the drive device 4, realizing a foolproof design, so that if one side fails to clamp or malfunctions, the other side can still position and clamp the material box 5. Furthermore, the positioning pin structure 23 of the second positioning member 31 further improves the positioning accuracy. When placing the material box 5, the horizontal drive device 41 and the vertical drive device 42 corresponding to the first positioning member 21 and the second positioning member 31 in the material box storage position 11 of the material box 5 work simultaneously to clamp and position the material box 5 from both sides inside the material box storage position 11.

[0037] Furthermore, the bottom of the transverse fixed beam 32 is connected to a transverse moving slide rail 24. The transverse fixed beam 32 is slidably connected to the transverse moving slide rail 24, thereby simultaneously driving multiple second positioning members 31 on the transverse fixed beam 32 to reciprocate along the second direction.

[0038] Optionally and preferably, the drive device 4 is a cylinder.

[0039] Furthermore, this application also provides an automatic tool preparation machine, wherein the automatic tool preparation machine is equipped with the aforementioned positioning and clamping mechanism at the station for placing the material box 5. The automatic tool preparation machine further improves the stability of the tool preparation system by using the aforementioned clamping and positioning mechanism to position the material box during tool preparation and retraction.

[0040] The automatic tool preparation machine includes a material distribution component, a tool preparation component, and a tool magazine. The material distribution component includes an infeed track and an outfeed track. The infeed track is positioned parallel to the top of the outfeed track and is used to transport tool boxes to be prepared to the tool preparation component. Once prepared, the tool boxes are discharged via the outfeed track. The tool preparation component retrieves drill bits from the tool magazine and transfers the drill bits stored in the tool magazine to the tool boxes based on their identification codes. It then transfers the prepared tool boxes to the material distribution component. The tool magazine includes a tool preparation area shelf and a clamping device. The clamping device clamps tool boxes from the tool preparation area shelf and transfers them to the tool preparation component.

[0041] The beneficial effects of using the embodiments of this application are as follows:

[0042] 1. This application provides a material box with an identification code and uses the positioning pin structure of the positioning clamping mechanism to achieve the clamping and positioning of the material box, thereby further improving the positioning accuracy of the material box and realizing the positioning of material boxes with different precision and size.

[0043] 2. This application uses a positioning pin structure and an elastic element to position the material box together. The foolproof design on both sides of the clamping and positioning mechanism ensures the clamping and positioning effect on one side, further improving the stability of the clamping and positioning mechanism.

[0044] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. This application is not limited to the exact structures described above and illustrated in the accompanying drawings, and it should not be considered that the specific implementation of this application is limited to these descriptions. For those skilled in the art, various changes and modifications made without departing from the concept of this application should be considered to fall within the protection scope of this application.
