[0047] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

[0048] As Figure 1 and Figure 2 The utility model discloses a kind of CNC machine tools 100 provided in the embodiment, including first base 110, CNC machine table 120, tool system (not shown in drawing) and automatic feeding and discharging device for CNC machine table, CNC machine table 120 can carry workpiece 10, tool system is used to process workpiece 10. CNC machine table 120 movably arranged in first base 110, CNC machine table 120 can be moved relative to first base 110 along first direction and second direction.

[0049] Exemplarily, first direction can be the length direction of first base 110, and second direction can be the width direction of first base 110. When processing workpiece 10, the position of CNC machine table 120 is moved along first direction and second direction, so that the multi-point processing of tool system to workpiece 10 can be realized.

[0050] Among them, tool system can be set to cut, drill and other various processing to workpiece 10, and can be determined according to actual conditions, which is not limited here.

[0051] As Figures 1-9As shown, the automatic feeding and discharging device for the CNC machine provided in the embodiment comprises a CNC jig 1, a tray 2, a storage mechanism 3 and a working mechanism 4.

[0052] The CNC jig 1 is fixedly connected to the CNC machine 120, and the CNC jig 1 is provided with a machining area 11 for accommodating the workpiece 10.

[0053] The tray 2 can accommodate a plurality of workpieces 10.

[0054] The storage mechanism 3 is fixedly connected to the CNC machine 120, and the storage mechanism 3 can carry the tray 2.

[0055] The working mechanism 4 is movably arranged on the first base 110, and the working mechanism 4 can vertically ascend and descend relative to the first base 110. The working mechanism 4 is configured to transfer the workpiece 10 between the tray 2 and the machining area 11. The working mechanism 4 comprises a pressing head 41 and a clamping head 42. The pressing head 41 is used to press the workpiece 10, and the clamping head 42 is configured to clamp or release the workpiece 10 when the pressing head 41 acts on the workpiece 10.

[0056] In specific implementation, the operator first places a plurality of workpieces 10 in the tray 2, and then places the tray 2 loaded with the workpieces 10 on the storage mechanism 3. Then the CNC machine 120 is started, and the CNC machine 120 drives the storage mechanism 3 to move in the first direction and the second direction, so that the tray 2 on the storage mechanism 3 is located below the working mechanism 4. Then the working mechanism 4 is started to move to approach the tray 2 and grab the workpiece 10 in the tray 2, so that the workpiece 10 is separated from the tray 2. Then the CNC machine 120 is moved to move the CNC jig 1 to below the working mechanism 4, and the workpiece 10 grabbed by the working mechanism 4 is placed in the machining area 11 of the CNC jig 1. At this time, the tool system starts to process the workpiece 10 in the CNC jig 1. After processing, the CNC machine 120 and the working mechanism 4 are moved to transfer the processed workpiece 10 to the storage mechanism 3. In this way, the working mechanism 4 repeatedly transfers the workpiece 10 between the tray 2 and the machining area 11 until all the workpieces 10 in the tray 2 are processed.

[0057] During the transfer of the workpiece 10 by the working mechanism 4, the pressing head 41 first presses the workpiece 10 to keep the workpiece 10 stable, and then the clamping head 42 clamps the workpiece 10. When discharging, the clamping head 42 is first released from the workpiece 10, and then the pressing head 41 is separated from the workpiece 10, so that the clamping head 42 can be ensured not to carry the workpiece 10 when the workpiece 10 is released.

[0058] The automatic feeding and discharging device for the CNC machine and the CNC machine tool provided by the embodiment can realize automatic feeding and discharging during the whole machining process through the movement of the working mechanism 4 and the CNC machine 120, without manual feeding and discharging of multiple workpieces 10 one by one, that is, the machining of all workpieces 10 in the tray 2 can be completed by starting the device once, avoiding the multiple stoppage of the device in the middle of the process due to manual feeding and discharging in the traditional way. In this way, not only the labor cost is reduced, but also the frequency of starting and stopping the device is reduced, the continuous operation of the CNC machine tool is maintained, and the machining efficiency is greatly improved. In addition, the cooperation of the clamping head 42 and the pressing head 41 of the working mechanism 4 ensures the stability of the workpiece 10 during the transfer process, effectively improving the reliability of the automatic operation.

[0059] Optionally, as shown in Figure 6 The working mechanism 4 includes a plurality of pressing heads 41 and a plurality of clamping heads 42, and the number of the pressing heads 41 is the same as that of the clamping heads 42. In this way, the plurality of pressing heads 41 and the plurality of clamping heads 42 can act on the plurality of workpieces 10 at the same time, which is beneficial to improve the efficiency of material taking and discharging. Moreover, the plurality of pressing heads 41 press the plurality of workpieces 10 at the same time, which is beneficial to tightly press the plurality of workpieces 10 at the same height, thereby ensuring that the plurality of workpieces 10 have the same height during subsequent machining, avoiding the position deviation problem caused by the inconsistent height, and improving the machining precision of the workpiece 10.

[0060] As shown in Figure 6 In the embodiment, the number of the pressing heads 41 is 5, and the number of the clamping heads 42 is 5, but it is not limited thereto. For example, the number of the pressing heads 41 and the clamping heads 42 can be 6, 7, 8, etc., which can be determined according to actual conditions.

[0061] As shown in Figure 6 In some embodiments, the clamping head 42 includes a first clamping part 421 and a second clamping part 422, and the workpiece 10 is configured to at least partially extend between the first clamping part 421 and the second clamping part 422. The first clamping part 421 is provided as a fixed part, and the second clamping part 422 can be close to the first clamping part 421 to clamp the workpiece 10, or away from the first clamping part 421 to release the workpiece 10.

[0062] Through such a design, the fixed design of the first clamping part 421 and the movable design of the second clamping part 422 simplify the clamping action. The first clamping part 421 as a fixed part abuts against the workpiece 10, which can provide stable support for the workpiece 10, and is beneficial to improve the stability during clamping.

[0063] As shown in Figure 6As shown, in some embodiments, the working mechanism 4 further comprises a carrier 43, the first clamping part 421 is fixedly connected to the carrier 43, the second clamping part 422 is movably connected to the carrier 43, and the pressing head 41 is movably connected to the carrier 43. The pressing head 41 can be vertically lifted relative to the carrier 43, and can be moved to between the first clamping part 421 and the second clamping part 422 and press against the top surface of the workpiece 10. The carrier 43 can be vertically lifted relative to the first base 110 and synchronously move the pressing head 41 and the clamping head 42.

[0064] Specifically, taking the clamping of the workpiece 10 as an example, first, the carrier 43 is lowered to an appropriate height, so that the first clamping part 421 abuts against the workpiece 10, then the pressing head 41 is vertically lowered to between the first clamping part 421 and the second clamping part 422 until the pressing head 41 presses against the top surface of the workpiece 10, and finally the second clamping part 422 is moved so that the clamping head 42 clamps the workpiece 10. At this time, the carrier 43 can be raised for subsequent transfer of the workpiece 10.

[0065] Through such a design, the pressing head 41 and the clamping head 42 can be integrated on the carrier 43, which is beneficial to simplify the structure. Moreover, the pressing head 41 is arranged to move between the first clamping part 421 and the second clamping part 422, so that the structure is more compact, and the operation of pressing the workpiece 10 and clamping the workpiece 10 is also more smooth.

[0066] Further, the carrier 43 is provided with a first driving member 44 and a second driving member 45. The second clamping part 422 is connected to the first driving member 44, and the first driving member 44 can drive the second clamping part 422 to move close to or away from the first clamping part 421. The pressing head 41 is connected to the second driving member 45, and the second driving member 45 can drive the pressing head 41 to vertically lift.

[0067] Through the first driving member 44 and the second driving member 45 to control the second clamping part 422 and the pressing head 41 respectively, the second clamping part 422 and the pressing head 41 can be allowed to move independently. This independent driving mode provides greater operational flexibility, so that the clamping and pressing actions can be flexibly adjusted according to the position and shape of the workpiece 10, thereby facilitating to improve the adaptability of the working mechanism 4 to different workpieces 10.

[0068] Optionally, the first driving member 44 can be arranged as a clamping cylinder, a servo motor, etc., which is not limited here.

[0069] Optionally, the second driving member 45 can be arranged as a telescopic cylinder, an electric push rod, etc., which is not limited here.

[0070] For example, Figure 6As shown, in some embodiments, the first base 110 is provided with a third driving member 111 , the supporting member 43 is connected to the third driving member 111 , and the third driving member 111 can drive the supporting member 43 to vertically rise and fall relative to the first base 110 .

[0071] Through such an arrangement, the vertical lifting operation of the carrier 43 can be smoothly controlled by the third driving member 111, and the height of the clamping head 42 can be accurately adjusted, which is beneficial to improving the operational flexibility of the operating mechanism 4 and enhancing the degree of automation.

[0072] Optionally, the third driving member 111 can be configured as a telescopic cylinder, an electric push rod, etc., which is not specifically limited here.

[0073] like Figures 7-9 As shown, in some embodiments, the material storage mechanism 3 includes a second base 31, a carrying platform 32, a first material box 33, and a second material box 34. The second base 31 is fixedly connected to the CNC machine 120, the carrying platform 32 is disposed on the second base 31, the material tray 2 can be placed on the carrying platform 32, and the first material box 33 and the second material box 34 are disposed on the carrying platform 32. The first material box 33 is used to accommodate processed workpieces 10, and the second material box 34 is used to accommodate workpieces 10 that have generated an alarm during processing. In this arrangement, the first material box 33 and the second material box 34 can achieve classified storage of workpieces 10, facilitating subsequent processing.

[0074] like Figures 7-10 As shown, in some embodiments, the storage mechanism 3 also includes a cover 35, which is rotatably connected to the second base 31, and the cover 35 has a first position and a second position. When the cover 35 is rotated to the first position relative to the second base 31, the cover 35 is located on the top of the supporting platform 32 and covers the material tray 2, the first material box 33 and the second material box 34. When the cover 35 is rotated to the second position relative to the second base 31, the material tray 2, the first material box 33 and the second material box 34 are all exposed.

[0075] like Figure 8 and Figure 9 As shown, the cover 35 is in the second position, at which time the operating mechanism 4 can grab the workpiece 10 in the tray 2 and put the processed workpiece 10 into the first material box 33 or the second material box 34. Figure 10 As shown, the cover 35 is at the first position at this time, and the cover 35 covers the material tray 2 , the first material box 33 and the second material box 34 .

[0076] By setting the cover 35 as a rotatable structure, it can be flexibly switched between the first position and the second position. When it is needed to take materials from the tray 2 or put materials into the first material box 33 and the second material box 34, the cover 35 is rotated to the second position, so that the cover 35 does not affect the normal operation of the work mechanism 4. When the workpiece 10 in the CNC jig 1 is processed, the cover 35 can be rotated to the first position, so that the cover 35 covers the tray 2, the first material box 33 and the second material box 34, so as to protect the tray 2, the first material box 33 and the second material box 34 from being polluted by cutting fluid, aluminum scraps and other impurities during processing.

[0077] As shown in Figure 7 some embodiments, the material storage mechanism 3 further comprises a fourth driving member 36, which comprises a fixed end 361 and a telescopic end 362. The fixed end 361 is rotatably connected to the second base 31, and the telescopic end 362 is rotatably connected to the cover 35. The telescopic end 362 can be extended or retracted relative to the fixed end 361 to drive the cover 35 to rotate relative to the second base 31.

[0078] For example, in the orientation shown in Figure 7 , the cover 35 is in the second position. When the telescopic end 362 is retracted relative to the fixed end 361, it can pull the cover 35 to rotate from the second position to the first position. When the cover 35 is in the first position, the telescopic end 362 is extended relative to the fixed end 361, so as to push the cover 35 to switch from the first position to the second position.

[0079] By controlling the extension and retraction of the fourth driving member 36, the cover 35 can be automatically switched between the first position and the second position, so as to realize automatic opening and closing without manual intervention, thereby improving the automation degree of the material storage mechanism 3.

[0080] Optionally, the fourth driving member 36 can be a telescopic cylinder, an electric push rod or the like, which is not limited here.

[0081] As shown in Figures 7-10 some embodiments, a buffer structure 37 is arranged between the cover 35 and the second base 31. The buffer structure 37 comprises a stopper 371, a first buffer 372 and a second buffer 373. The first buffer 372 and the second buffer 373 are arranged at intervals on the second base 31. The stopper 371 is connected to the cover 35 and rotates together with the cover 35. The stopper 371 is provided with a first protruding portion 3711 and a second protruding portion 3712. When the cover 35 is in the first position, the first protruding portion 3711 abuts against the first buffer 372. When the cover 35 is in the second position, the second protruding portion 3712 abuts against the second buffer 373.

[0082] Through the arrangement, when the cover 35 rotates to the first position or the second position, the protruding portions on the stopper 371 respectively contact the corresponding buffers, play a buffering role, avoid the cover 35 from directly impacting the second base 31, effectively reduce mechanical impact, are beneficial to reduce the abrasion between the cover 35 and the second base 31, prolong the service life of the components.

[0083] Optionally, the first buffer 372 and the second buffer 373 include but are not limited to oil pressure buffers.

[0084] As shown in Figure 8 and Figure 9 In some embodiments, each of the opposite ends of the cover 35 is provided with a buffer structure 37. Through the arrangement, the two buffer structures 37 simultaneously act when the cover 35 rotates to the first position or the second position, respectively provide symmetrical buffer forces at the opposite ends, so that the cover 35 is subjected to more uniform and balanced buffer forces in any position.

[0085] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or changes can be made.
