[0032] See also Figure 2 , Figure 4 As shown, the utility model is a multifunctional drilling instrument for punching holes in aluminum plates, comprising a drilling instrument body 1, a drilling table 2 is arranged on the inner wall of the drilling instrument body 1, a lifting assembly 3 is fixedly installed on the top of the drilling table 2, a guide assembly 5 is arranged on the outer surface of the lifting assembly 3, a punching assembly 7 is fixedly installed on the bottom of the guide assembly 5, a fixing column 8 is fixedly installed on the bottom of the punching assembly 7, a cutter disc 9 is sleeved on the outer surface of the fixing column 8, a supporting spring 4 is fixedly installed on the top of the cutter disc 9, a threaded sleeve 10 is arranged on the top of the cutter disc 9, a punching cutter head 11 is connected to the internal thread of the threaded sleeve 10, a threaded column 12 is fixedly installed on the outer surface of the punching cutter head 11, a cutter column 13 is fixedly installed on the output end of the punching assembly 7, a cross notch 14 is provided on the outer surface of the cutter column 13, and an internal thread is provided on the inner wall of the cutter column 13.

[0033] When in use, the knife column 13 is fixed to the bottom of the punching assembly 7. When it is necessary to punch a hole in the aluminum plate, the lifting assembly 3 is started to drive the guide assembly 5 to move downward and drive the punching assembly 7 to move downward synchronously so that the knife column 13 drives the cutter head inside it to gradually approach the upper surface of the aluminum plate to be punched. Then, the punching assembly 7 is started to drive the knife column 13 to drive the cutter head to rotate at high speed to drill holes in the aluminum plate. When it is necessary to process different hole types, the cutter head inside the loose knife column 13 is rotated, and the guide assembly 5 is started to drive the punching assembly 7 to move horizontally to the side away from the lifting assembly 3 until it moves to the end of the guide assembly 5 and stops. At this time, the knife disc 9 is pushed to move downward along the fixed column 8 and drive the support at the top The support spring 4 is stretched until the cutter disc 9 moves close to the outside of the cutter column 13, and then the punching cutter head 11 inside the threaded sleeve 10 is rotated according to the hole type to be processed to disengage it from the inside, and inserted from bottom to top along the corresponding notch of the cross notch 14 on the outside of the cutter column 13 until the threaded column 12 is close to the inner wall of the cutter column 13 and then rotated and locked to fix the punching cutter head 11 to the cutter column 13. The disassembled cutter head is inserted into the interior of the threaded sleeve 10 corresponding to the replaced punching cutter head 11 again and locked. Then the cutter disc 9 is loosened and automatically moved to its original position through the elastic expansion and contraction action of the support spring 4 on its top, and the guide assembly 5 is started again to drive the punching assembly 7 to reverse displacement and reset to complete the replacement action.

[0034] The utility model fixes the punching assembly 7 and the guide assembly 5. When different hole types need to be processed, the punching assembly 7 is controlled by the guide assembly 5 to perform lateral displacement, so that the punching assembly 7 can be moved away from the original punching processing position, thereby increasing the replacement operation space. At the same time, the cutter disc 9 is elastically supported on the outside of the fixed column 8 and is located on the top of the cutter column 13. When the cutter head needs to be replaced, its position is changed by pulling the cutter disc 9, and the fixed position of the punching cutter head 11 on its outside corresponds to the notch of the cross notch 14, so that the punching cutter head 11 in any direction can be quickly inserted into the inside of the cross notch 14 and connected to the cutter column 13 when it is taken out from the inside of the threaded sleeve 10, so as to achieve the effect of quickly replacing the punching cutter head 11 of different processing hole types without disassembling the cutter column 13, thereby increasing the efficiency of cutter head replacement and facilitating the operation of processing different hole types on the aluminum plate.

[0035] In one embodiment, for the above-mentioned lifting assembly 3, the number of the lifting assembly 3 and the guide assembly 5 are both several, the number of the threaded sleeves 10 and the punching cutter heads 11 are evenly several, and the several threaded sleeves 10 and the punching cutter heads 11 are distributed in a cross shape on the outside of the cutter disc 9.

[0036] The cooperation of several lifting assemblies 3 and guide assemblies 5 facilitates the provision of lifting displacement and guiding functions for multiple sets of punching assemblies 7, so that multiple sets of punching operations can be performed simultaneously inside the drilling instrument body 1. Several threaded sleeves 10 and punching cutter heads 11 are distributed in a cross shape on the outside of the cutter disc 9, and their positions correspond to the through positions of the cross slot 14, so that when different punching cutter heads 11 are replaced, their tops can be quickly inserted into the inside of the cross slot 14 so that the threaded column 12 and the inner wall of the cutter column 13 are threadedly locked and fixed, thereby facilitating the rapid replacement of different punching cutter heads 11 for each set of punching assemblies 7.

[0037] In one embodiment, for the above-mentioned lifting assembly 3, the lifting assembly 3 includes an electric slide rail 301, a driving motor 302 is arranged on the back of the electric slide rail 301, and a guide slider 303 is slidably installed on the front of the electric slide rail 301.

[0038] By starting the driving motor 302, the guide sliding block 303 can be driven to slide longitudinally outside the electric slide rail 301. The sliding of the guide sliding block 303 drives the guide component 5 and the punching component 7 outside thereof to move, thereby providing lifting and displacement power for the punching component 7, thereby increasing the punching operation efficiency of the punching component 7.

[0039] In one embodiment, for the guide assembly 5, the guide assembly 5 includes a guide rod 501, one end of the guide rod 501 is fixedly connected to the guide slider 303, one end of the guide rod 501 is fixedly mounted with a fixing plate 502, the outer surface of the fixing plate 502 is fixedly mounted with a guide motor 503, and the output end of the guide motor 503 is fixedly mounted with a guide screw 504;

[0040] A guide block 506 is slidably mounted on the outer surface of the guide rod 501 , a sliding sleeve 507 is fixedly mounted on one side of the guide block 506 , and the guide screw 504 penetrates into the interior of the sliding sleeve 507 and is threadedly connected thereto.

[0041] When the guide motor 503 is started, it drives the guide screw 504 to rotate to drive the sliding sleeve 507 outside it to move laterally outside it. While the sliding sleeve 507 moves, it drives the guide block 506 to move along the outside of the guide rod 501, so that the guide block 506 limits the displacement of the sliding sleeve 507 and drives the bottom punching assembly 7 to move together.

[0042] By fixing one end of the guide rod 501 to the guide sliding block 303, when the guide sliding block 303 is driven to perform longitudinal displacement, the guide rod 501 and the punching assembly 7 can be driven to perform longitudinal displacement synchronously, and through the cooperation of the guide motor 503 and the guide screw 504, the sliding sleeve 507 can simultaneously move the limiting guide block 506 on one side and drive the bottom punching assembly 7 to perform lateral displacement synchronously, thereby facilitating the provision of lifting and lateral displacement driving force for the punching assembly 7 at the same time, making it more convenient and efficient when performing punching operations and replacing the cutter head.

[0043] In one embodiment, for the above-mentioned punching assembly 7, the punching assembly 7 includes a punching motor 701, a mounting plate 702 is fixedly installed on the top of the punching motor 701, the mounting plate 702 is fixedly connected to the bottom of the guide block 506, and a punching shaft is provided at the output end of the punching motor 701, and the bottom of the punching shaft is fixedly connected to the knife column 13.

[0044] The top of the knife column 13 is fixed to the punching shaft. When the punching motor 701 is started to drive the punching shaft to rotate, the knife column 13 is driven to rotate, so that the punching cutter head 11 inside the knife column 13 rotates synchronously and contacts the aluminum plate to punch holes. The mounting plate 702 is fixed to the guide block 506. When the guide block 506 follows the guide rod 501 to rise and fall, the punching motor 701 at its bottom is driven to rise and fall. When the guide block 506 moves laterally outside the guide rod 501, it drives the punching motor 701 to move laterally synchronously.

[0045] By fixing the top of the punching motor 701 to the guide block 506, the electric slide rail 301 and the guide rod 501 cooperate to provide a longitudinal and lateral displacement path for the punching motor 701. At the same time, the top of the knife column 13 is fixed to the punching shaft, so that the punching head 11 and the knife column 13 have a flexible installation space, so that the knife column 13 can quickly install different punching heads 11 without disassembly.

[0046] In one embodiment, for the above-mentioned drilling table 2, a positioning plate 15 is provided on the upper surface of the drilling table 2, and the number of the positioning plates 15 is several. A limiting top plate 16 is slidably installed on the top of the drilling table 2, and a tooth plate 17 is provided on one side of the limiting top plate 16. The outer surface of the tooth plate 17 is meshed with a toothed disc 18, and a rotating screw 19 is fixedly installed inside the toothed disc 18. The rotating screw 19 passes through the toothed disc 18 and extends to the interior of the drilling table 2 and is threadedly connected thereto.

[0047] Since multiple sets of punching components 7 are arranged on the top of the drilling table 2, multiple sets of positioning plates 15 are placed under each set of punching components 7 respectively. When multiple sets of aluminum plates need to be processed at the same time, each set of aluminum plates can be placed on the corresponding positioning plates 15 respectively, and the rotating screw 19 is rotated to drive the toothed disc 18 to rotate to drive the toothed plate 17 to drive the limiting top plate 16 to slide and move until the top end of the limiting top plate 16 is tightly pressed against the rear side of the positioning plate 15. The rotating screw 19 is stopped to make the limiting top plate 16 limit and fix the positioning plate 15, so as to prevent the positioning plate 15 at the bottom of the aluminum plate from shaking and shifting during the drilling process, resulting in poor drilling quality.

[0048] In one embodiment, for the drilling instrument body 1 , a slideway 20 is disposed on the inner wall of the drilling instrument body 1 , and a sealing door 21 is slidably mounted on the inner wall of the slideway 20 .

[0049] A symmetrical slide 20 is provided on the inner side of the drilling instrument body 1 so that the sealing door 21 is slidably connected thereto. When the aluminum plate is being punched, the sealing door 21 and the drilling instrument body 1 are in a closed state to prevent punching debris from splashing. When it is necessary to remove materials, the sealing door 21 is pushed to slide upward along the slide, that is, its supporting position is changed, so that the drilling window of the drilling instrument body 1 can be opened to facilitate material removal.

[0050] In one embodiment, for the drilling instrument body 1 , a positioning column 22 is fixedly installed on the inner wall of the drilling instrument body 1 . There are several positioning columns 22 , and gaps are left between each of the positioning columns 22 .

[0051] A plurality of positioning posts 22 are symmetrically located on both sides of each set of electric slide rails 301 , and the gap between them facilitates providing a center positioning function for the electric slide rails 301 , thereby facilitating a positioning and installation function for multiple sets of electric slide rails 301 .

[0052] In summary, with the aid of the above-mentioned technical scheme of the utility model, by arranging multiple groups of electric slide rails 301 on the inner side of the drilling instrument body 1, when multiple groups of aluminum plates need to be punched at the same time, the aluminum plates to be punched are placed on the corresponding positioning plates 15 respectively, and the positioning plates 15 are clamped and clamped by the limiting top plate 16 to prevent them from loosening, and the punching motor 701 is started to drive the punching shaft to drive the knife column 13 and the knife head inside it to operate to punch the aluminum plate. When different hole types need to be processed on the aluminum plate, the driving motor 302 is started to drive the guide sliding block 303 to drive the guide rod 501 and the punching motor 701 at the bottom and other components to move longitudinally along the electric slide rail 301, so that the knife column 13 moves upward away from the processing position, and then the guide motor 503 is driven to rotate the guide screw 504 to drive the sliding sleeve 507 to move, and at the same time drive the guide block 506 and the punching motor 701 to move synchronously in the direction away from the electric slide rail 301, and then the cutter disc is pulled After the screw threaded sleeve 10 is disengaged from the inner wall of the cross slot 14, the screw threaded sleeve 10 is pulled upward and rotated to lock the inner wall of the screw threaded sleeve 10 and ...
