DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Example 1, reference Figure 1 , provides a loading and unloading mechanism for a CNC gantry milling machine, including a base 100, which is provided with a rotating table 101, wherein the rotating table 101 is rotatably installed on the base 100, and a motor-like structure is arranged on the base 100, which can drive the rotating table 101 to rotate.

[0033] like Figure 1 and Figure 2 The mechanism also includes an interlaced circulation platform 200, which includes at least two sub-platforms 201. At least two sub-platforms 201 are arranged on the rotating table 101 with the rotation axis of the rotating table 101 as the center of the circle. In this embodiment, the number of sub-platforms 201 is two, and the two sub-platforms 201 are arranged in a circle with the rotation axis of the rotating table 101 as the axis center. The purpose of installing the sub-platforms 201 on the rotating table 101 is to reduce the time occupied by loading and unloading. The existing loading and unloading mechanism needs to first remove the material that has been processed on the milling machine from the milling machine fixture for placement, and then clamp the material to be processed and transport the material to be processed to the milling machine fixture position.

[0034] like Figure 4 , we mark the two sub-platforms 201 as the first platform 202 and the second platform 203 respectively. When the material processing is completed, the material to be processed is clamped on the second platform 203, and then the loading and unloading mechanism moves to let the first platform 202 reach the corresponding position of the milling machine fixture, and the processed material is taken down through the first platform 202, and then the rotating table 101 is rotated 180 degrees, and the first platform 202 is rotated to the original position of the second platform 203, and the second platform 203 is rotated to the corresponding position of the milling machine fixture, so that the material to be processed is placed on the milling machine fixture. Compared with the prior art, it can reduce the time occupied by loading and unloading, thereby improving the processing efficiency of the milling machine.

[0035] like Figure 2The mechanism also includes a driving component 300, including a power member 301 installed on the sub-platform 201, and a transmission member 302 connected to the power member 301; a moving component 400, which is arranged in pairs on the sub-platform 201 and is connected to the transmission member 302; a clamping rod 500, which is installed on the moving component 400; the power member 301 drives the transmission member 302 to work, thereby transmitting power to the moving component 400, so that the moving component 400 can move, when the paired moving components 400 approach each other, the clamping rod 500 located on the moving component 400 approaches each other, so that the material can be clamped, and when the paired moving components 400 move away from each other, the clamping rod 500 located on the moving component 400 can release the clamping of the material.

[0036] like Figure 2 , Figure 3 and Figure 5 At least one group of placement holes 401 for installing the clamping rod 500 is provided on the moving component 400. The paired moving components 400 are symmetrically installed on the sub-platform 201. The moving component 400 has a first end and a second end that are far away from each other. In the same group of placement holes 401, when the distance between the midpoint line between the placement hole 401 and the first end and the second end is reduced, the distance between the placement hole 401 and the symmetry line of the paired moving components 400 is also reduced.

[0037] In this embodiment, two groups of placement holes 401 are developed on each movable component 400. When working, two clamping rods 500 can be installed on each movable component 400. The purpose of such arrangement is to be able to adapt to materials of different sizes. As shown in the figure, there are four placement holes in each group 401, and their positions are marked as the first hole 1, the second hole 2, the third hole 3 and the fourth hole 4 respectively. Referring to the accompanying drawings, we can see that in the same group of placement holes 401, the closer the placement hole 401 is to the midpoint line between the first end and the second end, the closer it is to the symmetry line of the paired movable components 400.

[0038] Therefore, when clamping smaller materials, we can respectively install the four clamping rods 500 at the first hole 1 position in the four groups of mounting holes 401 to obtain a smaller clamping range. When clamping larger materials, we can respectively install the four clamping rods 500 at the fourth hole 4 position in the four groups of mounting holes 401 to obtain a larger clamping range. By setting the position of the mounting holes 401, when clamping different materials, the position of the clamping rod 500 installed on the moving part 400 can be adjusted to obtain clamping ranges of different sizes, so that it can be applied to loading and unloading of materials of different sizes.

[0039] Example 2, reference Figure 2 , this embodiment is different from the first embodiment in that: Figure 2 and Figure 3 A guide rail 402 is installed on the sub-platform 201 , a movable sliding member 403 is installed on the guide rail 402 , and the movable member 400 is connected to the sliding member 403 .

[0040] There are two guide rails 402 and two sliding members 403 on the sub-platform 201. Both sliding members 403 can be movably installed between the two guide rails 402. The ends of the sliding members 403 can move on the guide rails 402. When the two sliding members 403 approach each other, they can drive the two moving parts 400 to approach each other, thereby driving the clamping rods 500 on the two moving parts 400 to approach each other, so as to clamp the material. When the two sliding members 403 move away from each other, they can drive the two moving parts 400 to move away from each other, thereby driving the clamping rods 500 on the two moving parts 400 to move away from each other, so as to release the clamped material.

[0041] Specifically, the power member 301 is a driving motor; the transmission member 302 includes a rotating rod 303 connected to the output shaft of the driving motor, and a convex shaft 304 arranged at the end of the rotating rod 303; a guide groove 404 is opened on the sliding member 403, and the convex shaft 304 extends to the inner side of the guide groove 404.

[0042] like Figure 3 When it is necessary to clamp the material, the output shaft of the driving motor rotates clockwise, driving the rotating rod 303 to rotate clockwise. During this process, the two convex shafts 304 rotate clockwise with the output shaft of the driving motor as the axis, which can reduce the horizontal distance between the two convex shafts 304 and the output shaft of the driving motor, thereby pulling the two sliding members 403 closer to each other, and then the clamping rods 500 are closer to each other to clamp the material.

[0043] When the material needs to be loosened, the output shaft of the driving motor rotates counterclockwise, driving the rotating rod 303 to rotate counterclockwise. During this process, the two cam shafts 304 rotate counterclockwise with the output shaft of the driving motor as the axis, which can increase the horizontal distance between the two cam shafts 304 and the output shaft of the driving motor, thereby pulling the two sliding members 403 away from each other, and then the clamping rods 500 move away from each other to loosen the material.

[0044] The rest of the structure is the same as that of Example 1.

[0045] Example 3, reference Figure 6 and Figure 7This embodiment is different from the above embodiments in that: when clamping materials of different sizes, it is necessary to adjust the position of the clamping rod 500. In order to be able to more conveniently adjust the position of the clamping rod 500, the loading and unloading mechanism for the CNC gantry milling machine also includes a connecting ring 600, and the clamping rod 500 is installed in the placement hole 401 through the connecting ring 600; a positioning component 700 is installed on the connecting ring 600, and the positioning component 700 includes an elastic member 701 installed on the connecting ring 600, and a fixing buckle 702 and a snap-on buckle 703 installed at both ends of the elastic member 701; the connecting ring 600 can be positioned on the inner side of the placement hole 401 through the fixing buckle 702, and the connecting ring 600 can be connected to the clamping rod 500 through the snap-on buckle 703.

[0046] Among them, the connecting ring 600 is sleeved on the inside of the clamping rod 500, and is buckled with the clamping rod 500 through the snap-fit ​​buckle 703. During installation, the connecting ring 600 can be sent into the inside of the placement hole 401. After being sent into the inside of the placement hole 401, the elastic member 701 can position the fixing buckle 702 on the inner side of the placement hole 401, thereby completing the positioning of the connecting ring 600, and then the clamping rod 500 is positioned on the inner side of the placement hole 401.

[0047] The elastic member 701 includes a slide post 705 slidably mounted on the connection, and a first elastic body 706 connected to the slide post 705 at one end and connected to the connecting ring 600 at the other end. In the absence of external force, the first elastic body 706 can maintain the position of the slide post 705. It should be noted that when the slide post 705 moves toward the clamping rod 500, the first elastic body 706 will be pulled up, and when the slide post 705 moves away from the clamping rod 500, the first elastic body 706 will be compressed, wherein the first elastic body 706 is a spring.

[0048] The connecting ring 600 is provided with an outer groove 602 penetrating to the radial outer wall and an inner groove 603 penetrating to the radial inner wall; one end of the sliding post 705 extends to the outer groove 602 , and the other end of the sliding post 705 extends to the inner groove 603 .

[0049] In this embodiment, the fixing buckle 702 is partially located on the inner side of the outer groove 602, and the snap-fit ​​buckle 703 is partially located on the inner side of the inner groove 603. When the first elastomer 706 is not affected by external force, under the action of the first elastomer 706, the end of the fixing buckle 702 away from the sliding column 705 will extend to the outside of the outer groove 602, and the end of the snap-fit ​​buckle 703 away from the sliding column 705 will extend to the outside of the inner groove 603, so that the fixing buckle 702 can remain snapped into the mounting hole 401, and the snap-fit ​​buckle 703 and the sliding column 705 can be stably connected.

[0050] Specifically, a groove 501 is provided on the clamping rod 500, and a latch tooth 502 is provided inside the groove 501 of the clamping rod 500; the snap-fit ​​buckle 703 can extend to the inner side of the groove 501 and latch with the latch tooth 502, and the depth of the latch tooth 502 needs to be smaller than the depth of the groove 501. Under the action of the first elastic body 706, the snap-fit ​​buckle 703 can enter the groove 501 and latch with the latch tooth 502, thereby completing the positioning of the clamping rod 500 by the connecting ring 600.

[0051] Furthermore, the movable component 400 is provided with a limiting groove 405 inside the seating hole 401, and the movable component 400 is provided with a fixing groove 406 in the limiting groove 405; a limiting block 601 is provided on the radial outer wall of the connecting ring 600, and when the connecting ring 600 slides inside the seating hole 401, the limiting block 601 can slide inside the limiting groove 405; the fixing buckle 702 can extend to the inner side of the fixing groove 406.

[0052] When the connecting ring 600 is sent into the seating hole 401, the limit block 601 slides inside the limit groove 405. First, it can prevent the connecting ring 600 from rotating inside the seating hole 401. Second, it can allow the fixing buckle 702 to be stably aligned with the fixing groove 406. As shown in the figure, the fixing groove 406 is opened at the bottom of the limit groove 405. The position of the limit block 601 corresponds to the position of the fixing buckle 702. Therefore, when the limit block 601 moves inside the limit groove 405, it can ensure that the fixing buckle 702 reaches the corresponding position of the fixing groove 406. When the positions of the fixing buckle 702 and the fixing groove 406 correspond, under the pulling force of the first elastic body 706, the pulling sliding column 705 can be slid, so that the fixing buckle 702 enters the inner side of the fixing groove 406, thereby completing the buckling of the fixing buckle 702 and the fixing groove 406.

[0053] The rest of the structure is the same as that of Example 2.

[0054] Example 4, reference Figures 6 to 9 This embodiment is different from the above embodiments in that: when clamping some thinner objects, the length of the extension of the clamping rod 500 needs to be adjusted to be smaller, and when clamping some thicker objects, the length of the extension of the clamping rod 500 needs to be larger. In order to facilitate the adjustment of the length of the clamping rod 500 extending out of the placement hole 401, the loading and unloading mechanism for the CNC gantry milling machine also includes an operating ring 800, which is rotatably mounted on the inner wall of the connecting ring 600; the inner wall of the operating ring 800 is provided with an inner protrusion 801, and the inner protrusion 801 extends to the inside of the groove 501; therefore, when the clamping rod 500 is rotated, the clamping rod 500 can drive the operating ring 800 to rotate synchronously through the inner protrusion 801.

[0055] The radial inner wall of the connecting ring 600 is further provided with an annular groove 604 , and the operating ring 800 is rotatably mounted inside the annular groove 604 .

[0056] The operating ring 800 is also provided with a center hole 802, and an inner deflection groove 803 and an outer deflection groove 804 connected to the center hole 802; the end of the inner deflection groove 803 away from the center hole 802 is deflected toward the center of the operating ring 800, and the end of the outer deflection groove 804 away from the center hole 802 is away from the center of the operating ring 800; the positioning component 700 also includes a force column 704 connected to the elastic member 701, the force column 704 is fixedly connected to the sliding column 705, and the force column 704 extends to the inner side of the center hole 802.

[0057] When the operating ring 800 is not rotated, the force-bearing column 704 is located in the center hole 802, the snap buckle 703 is snapped with the latch tooth 502, and the fixing buckle 702 is snapped with the fixing groove 406. When it is necessary to adjust the length of the clamping rod 500 extending to the outside of the placement hole 401, the clamping rod 500 can be rotated counterclockwise. At this time, the clamping rod 500 drives the operating ring 800 to rotate counterclockwise relative to the connecting ring 600, and the force-bearing column 704 reaches the outer offset groove 804 from the center hole 802. At this time, the force-bearing column 704 is pushed away from the clamping rod 500. The fixing buckle 702 can go deeper into the fixing groove 406, and the snap buckle 703 is disengaged from the latch tooth 502. At this time, the clamping rod 500 can be pushed or pulled so that the clamping rod 500 can move along the axial direction, thereby adjusting the extended length of the clamping rod 500 to meet the clamping requirements of materials of different thicknesses.

[0058] When the clamping rod 500 needs to replace the mounting hole 401, the clamping rod 500 can be rotated clockwise. At this time, the clamping rod 500 drives the operating ring 800 to rotate clockwise, and the force column 704 reaches the inner offset groove 803 from the center hole 802. At this time, the force column 704 is subjected to a pulling force in the direction close to the clamping rod 500. The force column 704 transmits the force to the sliding column 705, and the fixing buckle 702 disengages from the inside of the fixing groove 406, and the snap-on buckle 703 penetrates into between the snap teeth 502. At this time, the clamping rod 500 is pulled again, and the clamping rod 500 can drive the connecting ring 600 to disengage from the inside of the mounting hole 401.

[0059] It should be noted that the width of the groove 501 needs to be greater than the width of the snap buckle 703, and the placement hole 401 consists of two parts, namely an entry end and a through end, wherein the aperture of the entry end is adapted to the diameter of the connecting ring 600, and the diameter of the through end is smaller than the diameter of the connecting ring 600 and adapted to the diameter of the clamping rod 500.

[0060] Specifically, it also includes a restraining component 900; it includes a pressing body 901, which is fixed on the connecting ring 600; a limiting block 902, which is arranged in pairs on the operating ring 800; an arc column 903, which is installed between two pairs of limiting blocks 902, and the arc column 903 passes through the pressing body 901; a second elastic body 904, which is arranged between the limiting block 902 and the pressing body 901.

[0061] In this embodiment, there are two second elastic bodies 904, which are respectively located between the two limiting blocks 902 and the pressing body 901. The two second elastic bodies 904 are springs and are sleeved on the outer side of the arc column 903. Under the limitation of the two second elastic bodies 904, the position of the operating ring 800 can be maintained so that the force column 704 is located in the center hole 802. No matter whether the operating ring 800 rotates clockwise or counterclockwise, one of the second elastic bodies 904 will be pressed. When the external force disappears, the second elastic body 904 can push the operating ring 800 to reset, so that the force column 704 is re-located in the center hole 802. The effect is: when the clamping rod 500 and the operating ring 800 are not rotated, the entire positioning component 700 will not be affected by the operating ring 800.

[0062] The rest of the structure is the same as that of Example 3.
