[0023] Figures 1 to 4 It is the best embodiment of the utility model, and the following Figures 1 to 4 The utility model is further described.

[0024] like Figures 1 to 4 As shown, a precise hole punching device for building thermal insulation exterior wall comprises a gear frame 1, a fixed disk 4 is fixedly mounted on one end of the gear frame 1, a rotating shaft 5 is rotatably mounted on one side of the fixed disk 4, an adjusting disk 6 is rotatably mounted on the other end of the rotating shaft 5, a plurality of mounting openings are provided on one side of the fixed disk 4, an extrusion assembly is slidably mounted in the mounting opening, a mounting plate 7 is fixedly mounted on one side of the adjusting disk 6, a circular groove is provided on one side of the mounting plate 7, a fixing mechanism is fixedly mounted in the circular groove;

[0025] The fixing mechanism includes a limit plate 8, which is fixedly installed on the inner wall of the circular groove. A splicing block 9 is fixedly installed on one side of the limit plate 8. A plurality of limit openings are opened on the surface of the limit plate 8. Positioning components are slidably installed in the plurality of limit openings. A splicing groove block 10 is fixedly installed on the surface of the splicing block 9 through the positioning component. A fixing plate 11 is fixedly installed on one side of the splicing groove block 10. There is a gap between the splicing groove block 10 and the fixing plate 11.

[0026] By means of the above structure, the fixed disk 4 and the adjusting disk 6 have the same size, and the fixed disk 4 and the adjusting disk 6 are rotatably connected via the rotating shaft 5. The position where the limit disk 8 is rotatably installed still leaves space from the deepest position of the inner wall of the circular groove. The splicing block 9 is rectangular and corresponds to the corresponding splicing groove block 10. The splicing block 9 can be spliced ​​in the splicing groove block 10, and the fixed plate 11 is used to fix it to the insulation exterior wall.

[0027] Furthermore, the positioning assembly includes a plurality of positioning claws 13, and the plurality of positioning claws 13 are correspondingly slidably installed in the plurality of limiting openings, and a locking unit is rotatably installed on the inner wall of the circular groove.

[0028] With the above structure, the limit opening is opened with the center point of the limit plate 8 as the center, and there are four limit openings in total and they are perpendicular to each other. A positioning claw 13 is slidably installed in each limit opening, and there are four positioning claws 13 installed in total. The positioning claws 13 are L-shaped and can be fitted in the gap between the splicing slot block 10 and the fixed plate 11 for fixation.

[0029] Furthermore, the locking unit includes a worm wheel 15, which is rotatably installed in the circular groove. A plurality of U-shaped grooves 16 are provided on the surface of the worm wheel 15. A driving block 14 is fixedly installed on one side of each of the plurality of positioning claws 13. The plurality of driving blocks 14 are correspondingly slidably installed in the U-shaped groove 16. A rotating groove is provided on one side of the mounting plate 7. A rotating rod 17 is rotatably installed in the rotating groove. A worm 18 is fixedly installed on one end of the rotating rod 17. The worm 18 is meshed with the worm wheel 15.

[0030] With the above structure, the driving block 14 is slidably installed in the U-shaped groove 16 in a cylindrical shape. The U-shaped groove 16 is opened in a ring with the center point of the worm wheel 15 as the center, and the number is consistent with the number of limit grooves. When the worm 18 drives the worm wheel 15 to rotate, the worm wheel 15 will squeeze the positioning claws 13 through the four U-shaped grooves on its surface and cooperate with the limit blocks on the limit plate 8, so that the multiple positioning claws 13 are close to or away from each other.

[0031] Furthermore, the extrusion assembly includes multiple limit plates 19, which are correspondingly slidably installed in the installation opening, a hemispherical block 20 is fixedly installed on one side of the limit plate 19, multiple positioning grooves are opened on one side of the adjustment disk 6, and an extrusion spring 21 is fixedly installed on one side of the limit plate 19.

[0032] By means of the above structure, six mounting openings are opened in annular shapes at equal intervals, and the mounting openings are composed of a cylindrical groove and a rectangular groove. The hemispherical block 20 is slidably installed in the cylindrical groove, and the limiting plate 19 is slidably installed in the rectangular groove and the cylindrical groove can limit the limiting plate 19. The positioning grooves are also opened in six annular shapes at equal intervals corresponding to the hemispherical block 20. The hemispherical block 20 is combined in the positioning groove, and the fixed disk 4 and the adjusting disk 6 are limited by the extrusion spring 21. This limiting method will generate vibration during cutting, causing the hemispherical block 20 to vibrate continuously and reduce the connection stability. However, since multiple hemispherical blocks 20 are set, their stability can be improved, and when punching, one hand can be used to rotate the moving handle on the moving frame 2, and the other hand can be used to continuously stabilize the lower side of the moving frame 2 to assist in increasing the connection stability during the cutting process. Therefore, there will be no problem of rotation of the fixed disk 4 and the adjusting disk 6.

[0033] Furthermore, a moving frame 2 is slidably mounted on the surface of the gear frame 1 , and a punching machine body 3 is fixedly mounted on the upper side of the moving frame 2 .

[0034] With the above structure, the mobile frame 2 is consistent with the mobile frame 2 in the prior art. It is composed of a limiting tube, a gear and a moving handle attached to the surface of the gear frame 1. The gear is meshed on the upper side of the gear frame 1, and the mobile handle is fixedly connected to the gear. When in use, the mobile handle is rotated, and the gear is driven by the mobile handle to rotate. The gear drives the limiting tube to move on the gear frame 1, thereby making the mobile frame 2 move horizontally on the gear frame 1. The punching machine body 3 is a punching machine in the prior art and will not be described in detail here.

[0035] Furthermore, two fixing holes 12 are formed on the surface of the fixing plate 11 .

[0036] With the above structure, the fixing holes 12 are opened diagonally, which facilitates temporary and quick fixing of the fixing plate 11 by bolts and nuts.

[0037] Working principle: When the device is in use, first use bolts to fix the fixing plate 11 diagonally in the specified area of ​​the external wall where holes need to be punched for thermal insulation. After the fixing is completed, the tooth frame 1 is lifted, and the tooth frame 1 drives the fixing plate 4 to move. The fixing plate 4 drives the adjusting plate 6 to move through the rotating shaft 5, and the adjusting plate 6 drives the mounting plate 7 to move. The mounting plate 7 drives the limit plate 8 to move, and the limit plate 8 drives the splicing block 9 to move, so that the splicing block 9 gradually approaches and is inserted into the splicing groove block 10, so that the splicing block 9 is completely fitted in the splicing groove block 10 and remains motionless. At the same time, the other hand manually rotates the rotating rod 17, and the rotating rod 17 drives the worm The rod 18 rotates, and the worm 18 drives the worm wheel 15 to rotate. The worm wheel 15 drives the corresponding driving blocks 14 to move through the four U-shaped grooves 16, so that the four driving blocks 14 drive the corresponding positioning claws 13 to move under the limiting action of the four limiting openings, so that the four positioning claws 13 gradually approach and squeeze and fit the already spliced ​​splicing slot block 10. When the rotating rod 17 is rotated to the point where it cannot rotate, the rotating rod 17 is released, and the four positioning claws 13 are locked through the self-locking properties of the worm wheel 15 and the worm 18, so that the splicing block 9 is fixed to the splicing slot block 10, and the gear rack 1 is fixedly installed on the fixing plate 11.

[0038] After the fixation is completed, the punching machine body 3 is started, and the punching machine body 3 works to cut and punch holes in the insulation outer wall. At this time, the shoulder is placed against one end of the tooth frame 1 to keep it stable, one hand rotates the moving handle on the mobile frame 2, and the other hand continues to stabilize the lower side of the mobile frame 2 to accurately punch holes in the insulation wall. After the punching is completed, the punching machine body 3 is closed and the moving handle on the rotating mobile frame 2 is opened in the reverse direction, the punching knife on the punching machine body 3 is pulled out from the insulation outer wall, and the punching waste inside is taken out. Finally, the rotating rod 17 is rotated in the reverse direction. The rotating rod 17 drives the worm 18 to reverse and move the four positioning claws 13 away, so that the splicing block 9 and the splicing groove block 10 are unlocked, so that the entire tooth frame 1 is quickly removed and the fixing plate 11 is removed to complete the punching of the insulation outer wall.

[0039] During the punching process, if it is necessary to punch multiple insulation exterior wall holes with different angles, when one insulation exterior wall hole is punched, the movable frame 2 can be rotated forcefully by hand, and the movable frame 2 drives the gear rod to rotate, and the gear rod drives the fixed plate 4 to rotate, and the fixed plate 4 drives multiple hemispheres 20 to move. The hemisphere block 20 is squeezed into the installation groove by the positioning groove, so that the fixed plate 4 and the adjustment plate 6 are unlocked, and the rotation is continued until the hemisphere block 20 is aligned with the next positioning groove, and the reaction force of the extrusion spring 21 drives the limit plate 19 to move, and the limit plate 19 drives the hemisphere block 20 to move, and pushes the hemisphere block 20 back into the positioning groove, so that the fixed plate 4 and the adjustment plate 6 are repositioned, and then the punching machine body 3 is adjusted for angle offset, so that the punching area is adjusted without changing the position of the fixed plate 11, thereby improving the punching efficiency of the device.

[0040] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
