[0060] It should be noted that during the feeding of the drill mounted on the drill mounting mechanism 72, the L-shaped seat 711 is moved along the upper surface of the base 6 by the cylinder 713, and the dovetail groove and the dovetail block are used in cooperation to improve the stability of the drill feeding during cutting drilling.

[0061] Further, as shown in Figures 4-5 and Figures 9-10 , the plate clamping mechanism 82 includes a square ring frame 821 fixedly connected at both ends of the frame 81 and four L-shaped buckles 823 located between the two square ring frames 821, the four side edges of the square ring frame 821 are each provided with two cross grooves 822, each cross groove 822 is movably provided with a strip column 824, each strip column 824 is provided with a guide groove in the middle, and each guide groove is movably provided with a square bar slidingly connected in the corresponding cross groove 822, one end of each strip column 824 at each corner of the square ring frame 821 is fixedly connected with the corresponding L-shaped buckle 823, wherein the square bar and the corresponding strip column 824 are always arranged vertically to ensure that the two L-shaped buckles 823 horizontally or vertically relative to each other move stably under the power drive;

[0062] The middle of the four sides of the two square ring frames 821 is fixedly provided with an extension frame, one end of each extension frame is fixedly provided with a double-shaft motor 825, the two output shaft ends of the double-shaft motor 825 are fixedly connected with studs 826, the threads on the outer sides of the two output shaft ends of the same double-shaft motor 825 are oppositely arranged, the two studs 824 on the same side of the square ring frame 821 are threadedly sleeved on the outer sides of the corresponding studs 826, the inner side of each L-shaped buckle plate 823 is rotatably provided with a plurality of rotating cylinders 827 arranged at equal intervals, and the inner side of each L-shaped buckle plate 823 is also rollingly provided with a plurality of balls 828 arranged at equal intervals, wherein the design of the rotating cylinders 827 and the balls 828 can convert the contact static friction force between the metal plate to be machined fixed by the four L-shaped buckle plates 823 and the L-shaped buckle plates 823 into rolling friction, thereby reducing the energy loss when the target plate is driven forward by the plate feeding mechanism 83.

[0063] Further, the extension frame comprises a sleeve fixedly connected with the outer side of the square ring frame 821, a sleeve rod seat fixedly connected with the corresponding double-shaft motor 825, and a connecting spring fixedly connecting the sleeve and the sleeve rod seat, wherein the connecting spring and the end of the sleeve rod seat close to the sleeve are located inside the sleeve. The arrangement of the extension frame can ensure that the four L-shaped buckle plates 823 stably feed under the drive of the corresponding double-shaft motor 825 during the adjustment of the relative positions of the four L-shaped buckle plates 823 to complete the clamping of the target metal plate. In addition, an infrared range finder 829 is installed on the inclined surface area of the inclined table on the inner middle part of the L-shaped seat 711 to detect the relative position change between the L-shaped seat 711 and the debris collecting assembly 85, and then control the plate fixing mechanism 84 to limit and fix the metal plate after one-way pushing.

[0064] Further, as shown in Figures 7-9 The inside of the frame 81 is also provided with a splash-proof assembly 86, which comprises a triangular column 861 located between two vertically symmetrical L-shaped buckle plates 823, the triangular column 861 is fixedly connected with the corresponding L-shaped buckle plate 823, and the two ends of the two vertically corresponding triangular columns 861 are fixedly connected with metal springs 862, wherein each triangular column 861 is arranged in a right triangle structure, and the right angle side not in contact with the L-shaped buckle plate 823 moves in contact with the surface of the clamped and positioned metal plate.

[0065] It needs to be explained that in the process of clamping and positioning the target metal plate, the double-shaft motor 825 located at the top and bottom of the square ring frame 821 is used to drive the corresponding two studs 826 to rotate, so that the two studs 826 are driven to move towards each other and away from each other along the horizontal direction, so that the target metal plate is placed between the two L-shaped buckles 823 at the bottom, then the corresponding stud 826 is driven to rotate to make the two L-shaped buckles 823 move towards each other along the horizontal direction, and the two sides of the target metal plate in the vertical direction of the drill bit are clamped and positioned, then the double-shaft motor 825 located at both sides of the square ring frame 821 is used to drive the corresponding two studs 826 to rotate, and the two L-shaped buckles 823 arranged vertically are driven to move towards each other, and the two sides of the target metal plate parallel to the drilling direction of the drill bit are clamped and positioned, so that the four L-shaped buckles 823 are used to stably clamp and position the target metal plate.

[0066] Specifically, in the process of adjusting the relative positions of the four L-shaped buckles 823, the two groups of triangular columns 861 arranged vertically in a straight line also move towards each other, so that the bending angle of the metal spring 862 connected between the two triangular columns 861 changes, and a closed cavity is formed between the metal spring 862 and the corresponding triangular column 861 for preventing debris from flying during cutting and drilling, and the inclined surface of the triangular column 861 is used to guide the debris to fall into the debris collection assembly 85, and the collection of debris is completed.

[0067] When the clamping and positioning of the target metal plate is completed, the plate feeding mechanism 83 is used to drive the target metal plate to step forward, and after each single trip is completed, the L-shaped seat 711 is pushed to the direction of the surrounding frame 81 by the cylinder 713, so that the rotating drill bit completes the cutting and drilling of the target metal plate along with the feeding of the L-shaped seat 711, and in the process of pushing the L-shaped seat 711, when the infrared range finder 829 detects that the rotating drill bit is about to enter the inside of the surrounding frame 81, a signal is transmitted to the control end, and the plate fixing mechanism 84 is controlled by the control end to fix and position the pushed plate, so as to prevent the plate from moving during subsequent cutting and drilling and causing drilling deviation.

[0068] Further, Figure 4 and Figure 6As shown, the plate feeding mechanism 83 includes column blocks 831 fixed at the middle of both sides of the frame 81, and the top and bottom of each column block 831 is fixedly connected with a guide rod 832, and the outer side of each guide rod 832 arranged in a vertical line is movably sleeved with an ear plate 833 which is fitted with the outer side of the frame 81, and the opposite side of the two ear plates 833 located on the same side of the frame 81 is respectively provided with a connecting column 834 between the corresponding strip column 824, wherein one end of the connecting column 834 close to the corresponding ear plate 833 is fixedly connected with the ear plate 833, and the other end of the connecting column 834 is slidingly installed with the corresponding strip column 824 in the horizontal direction, but the connecting column 834 and the corresponding strip column 824 do not disengage, and the distance between the upper and lower feeding units can be adjusted according to the height of the target metal plate by the cooperation of the guide rod 832 and the connecting column 834. The two ear plates 833 arranged in a horizontal direction are rotatably installed with a rotating shaft, and the rotating shaft is driven to rotate by a servo motor installed on the outer side of one of the ear plates 833. The outer middle of each rotating shaft is fixedly sleeved with a driving disc 835, wherein the circumferential side of the driving disc 835 is provided with a recessed area, and a non-recessed area of the driving disc 835 is covered with a non-slip soft pad to better drive the target metal plate to push forward.

[0069] It should be noted that during the process of driving the target metal plate forward by the plate feeding mechanism 83, when the target metal plate is clamped and positioned by the plate clamping mechanism 82, the middle of the recessed area on the driving disc 835 is opposite to the target metal plate (this state is defined as the initial state), at this time, the driving disc 835 and the target metal plate are arranged apart, then the corresponding driving disc 835 is driven to rotate by the servo motor, when the non-recessed area on the driving disc 835 is in contact with the target metal plate after the driving disc 835 is rotated, the two are in an interference fit state, at this time, with the rotation of the driving disc 835, the target metal plate is driven to advance forward, in this process, the driving disc 835 is rotated one circle, and the feeding drill bit is used to complete a cutting drilling, and then the next round of plate advancing is performed.

[0070] Further, as shown in Figures 6-7 The plate fixing mechanism 84 includes a cylinder two 841 fixed on the outer side of the frame 81, and the telescopic end of the cylinder two 841 is fixedly connected with a straight plate 842, and the four corner positions of the straight plate 842 are fixedly provided with a circular rod 843 movably penetrating through the corresponding side of the frame 81, and one end of each circular rod 843 inside the frame 81 is fixedly installed with a vacuum chuck 844.

[0071] It should be noted that after each target metal plate is completed to be pushed forward, the control end will control the cylinder 2 841 to pull the straight plate 842 to be close to the surrounding frame 81 before cutting drilling, so as to push the round rod 843 to continue to insert into the inside of the surrounding frame 81, and synchronously drive the vacuum chuck 844 to be close to the target metal plate, when the vacuum chuck 844 moves to be in close contact with the corresponding side surface of the target metal plate, the vacuum chuck 844 is started to complete the suction of the target metal plate in the current state, so as to prevent the displacement of the plate during the subsequent cutting drilling process, which causes the drilling deviation and affects the quality of the finished product.

[0072] Further, as shown in Figure 4 and Figure 6 , the debris collecting assembly 85 includes a through groove opened in the bottom middle part of the surrounding frame 81 and a collecting bin fixedly arranged at the bottom of the surrounding frame 81 and communicated with the through groove, and a mesh plate is fixedly arranged in the inside of the collecting bin, which can divide the inside cavity of the collecting bin into a debris area and a cooling liquid recycling area, and filter the debris falling with the cooling liquid through the mesh plate, and a bin door is hingedly installed at a position above the mesh plate on the collecting bin, which facilitates cleaning the debris filtered out in the inside of the collecting bin, and a liquid pipe is communicated at a position below the mesh plate on the collecting bin, which is used for leading out the filtered cooling liquid for recycling.

[0076] Further, the docking assembly further includes a track frame 7210 fixedly arranged on the outer side of the outer cylinder 723 corresponding to the through groove one 725 and an adjusting cylinder 729 sleeved on the outer side of the outer cylinder 723, wherein the extension plate penetrating through the corresponding through groove one 725 is lapped on the upper end surface of the adjusting cylinder 729, the track frame 7210 is slidably installed with a sliding seat 7215, the top of the sliding seat 7215 is fixedly connected with an L-shaped frame 7211, the inner side of the L-shaped frame 7211 is fixedly provided with a clamping column 7214 movably penetrating through the corresponding through groove two 726, the length of the clamping column 7214 is greater than the sum of the vertical depths of the two communicating through grooves two 726, the inner sides of the L-shaped frame 7211 and the adjusting cylinder 729 are both fixedly provided with straight bars 7212 which are correspondingly arranged, and a swing arm 7213 is hinged between the two straight bars 7212 which are correspondingly arranged, the swing arm 7213 is provided with two groups, and the specific position distribution is shown in Figure 12The straight bar 7212 inside the adjusting cylinder 729 is fixed with a straight rod 7216 which is movably penetrated through the corresponding track frame 7210, and the outer side of the straight rod 7216 is sleeved with a straight spring which is fixedly connected with the corresponding straight bar 7212 and the track frame 7210, wherein, when the adjusting ring 728 is at the high position outside the outer cylinder 723, the end of the clamping column 7214 is completely hidden inside the through slot one 725 on the outer cylinder 723, and the straight rod 7216 is still in the state of movably penetrating through the corresponding track frame 7210, and at the same time, the straight spring is still in the compressed state.

[0077] It should be noted that, in the process of installing the drill bit to the drill bit mounting mechanism 72, the drill rod 2 of the drill bit is first inserted from the upper end of the inner cylinder 724, so that the insertion end of the drill rod 2 penetrates through the core hole at the center position of the bottom end of the inner cylinder 724, and during the insertion of the drill bit, the position of the mounting seat needs to be adjusted, so that the three clamping plates on the circumference of the circular plate are one-to-one corresponding to the three vertical grooves 7221 inside the inner cylinder 724, and move downward to the inside of the ring groove 7219. During this process, as the circular plate gradually moves downward, it will contact the ring plate before the clamping plate enters the inside of the ring groove 7219, so that after the clamping plate enters the inside of the ring groove 7219, the descending circular plate will push the ring plate to extrude the elastic expansion rod downward. After the clamping plate completely enters the inside of the ring groove 7219, the drill rod 2 is rotated, so that the mounting seat 1 is synchronously rotated to the position where the clamping plate is opposite to the clamping groove 7220, and then the external force applied to the drill bit is removed, so that the clamping plate is pushed into the corresponding clamping groove 7220 by the ring plate which is lifted and reset under the restoring force of the elastic expansion rod.

In this way, it can be ensured that after the inner cylinder 724 is inserted into the outer cylinder 723 (i.e. the circular plate is pushed by the square sleeve ring 7217), the through slots two 726 on the two are in one-to-one communication, and then the adjusting ring 728 is actuated to rotate, so that the adjusting ring 728 pushes the lifting frame 727 downward, and the descending lifting frame 727 pushes the adjusting cylinder 729 downward.

[0079] During the process of pushing the adjusting cylinder 729 downward, the straight bar 7212 inside the adjusting cylinder 729 will extrude the straight spring along the corresponding straight rod 7216, and at the same time, the angle of the swing arm 7213 between the corresponding two straight bars 7212 will change, thereby pushing the L-shaped frame 7211 to move inwardly to the direction of the inner cylinder 724 along the track frame 7210, so that the clamping column 7214 is inserted into the corresponding two through slots two 726. In this way, the installation of the drill bit can be completed, and the entire installation process can be performed without the need for tools, and the disassembly and assembly are convenient and fast.
