Description

Technical Field

[0001] The invention relates to the technical field of prefabricated wall punching, and in particular to a punching device for a building wall. Background Art

[0002] At a time when the construction industry is booming, prefabricated buildings are gradually becoming an important development direction in the construction field due to their many advantages such as high efficiency and environmental protection. Prefabricated walls are key components of prefabricated buildings. During the production and installation process, drilling operations are essential. These holes play a key role in the connection between prefabricated walls and other components, as well as the installation of facilities such as water and electricity lines. The quality of these holes directly affects the overall stability and functionality of the building.

[0003] At present, the drilling operation of prefabricated walls relies heavily on manually operated drilling equipment. When the drilling equipment is manually controlled to move forward, the drilling is very likely to deviate due to the lack of a precise and stable guiding mechanism. The deviation of the drilling not only makes it difficult to ensure the position accuracy of the holes in the prefabricated walls, but also affects the installation accuracy of subsequent components and reduces the stability of the building structure. It may also be necessary to re-drill or repair the holes that have been drilled due to hole deviation, which greatly increases the production cost and construction period.

[0004] Although manual drilling has the above obvious defects, it is undeniable that it has a certain flexibility in dealing with complex situations. The operator can rely on experience and the real-time status of the drill bit during drilling to pull out and insert the drill bit in time to avoid the drill bit being entangled by debris or stuck due to excessive resistance, and to prevent the equipment from being damaged due to long-term low-speed operation. Therefore, the development of a prefabricated wall drilling device that can accurately control the drilling direction and ensure drilling accuracy, and can respond flexibly like manual labor when encountering complex situations to avoid damage to the drill bit and equipment has become an important issue that needs to be urgently solved in the current construction industry. Summary of the invention

[0005] The purpose of the present invention is to provide a punching device for building walls, which solves the problem of low precision of existing manual punching in the background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: A drilling device for a building wall surface, including a device main body and a double-headed motor, a speed regulator and a drill chuck arranged inside the device main body. An inner sliding seat is slidably arranged inside the device main body. The double-headed motor and the speed regulator are installed inside the inner sliding seat. A plurality of second springs are evenly distributed between one side of the inner sliding seat and the inner wall of the device main body. One output end of the double-headed motor is connected to one end of the speed regulator, and the drill chuck is connected to the other end of the speed regulator and extends to the outside of the device main body. A reciprocating mechanism is further arranged inside the device main body, and the reciprocating mechanism is connected to the other output end of the double-headed motor. An adjusting mechanism is arranged between the reciprocating mechanism and the inner sliding seat. The adjusting mechanism includes a sliding rod connected to the reciprocating mechanism. A plurality of card slots are evenly distributed inside the sliding rod. The adjusting mechanism further includes a sliding frame movably connected to the inner sliding seat. A sliding groove is arranged inside the sliding frame. A sliding block is slidably connected inside the sliding groove. A card block corresponding to the card slot is movably arranged inside the sliding block. A third spring is arranged between the card block and the inner wall of the sliding block.

[0007] Further, the reciprocating mechanism is configured such that the range of each reciprocating motion is the distance between two card slots; the sliding range of the sliding block is the length of one card slot. When the reciprocating mechanism drives the sliding rod to move in the drilling direction, moving a distance of two card slots, the sliding block moves to the rightmost position inside the sliding groove. Subsequently, the sliding frame moves to the right by the length of one card slot, and the inner sliding seat, the double-headed motor and the speed regulator inside the inner sliding seat, as well as the drill chuck and the drill bit, all move to the right by the length of one card slot. Then, when the reciprocating mechanism drives the sliding rod to reset to the left, moving a distance of two card slots, since the card block is in close fit with the card slot, the sliding rod will first drive the card block and the sliding block to reset to the left when resetting. When the sliding block cannot continue to move when it reaches the left position inside the sliding groove, the card block will compress the third spring and retract into the sliding block. At this time, since the sliding block is located at the left position inside the sliding groove, the inner sliding seat has a certain movable range, and the drill bit can bounce back a certain distance after being blocked.

[0008] Further, an upper handle and a lower handle are respectively arranged at the top and bottom of the device main body. A rear support is installed at the tail of the device main body. The upper handle, the lower handle and the rear support are used for the operator to fix; A plurality of front positioning columns are evenly distributed around the drill chuck at the front end of the device main body. The front positioning columns are used to fit the prefabricated wall surface of the drilled hole and play a role in positioning.

[0009] Further, a sliding groove is arranged on the outer wall of the inner sliding seat close to the adjusting mechanism. The sliding frame is slidably connected up and down inside the sliding groove. A first spring is installed between the lower part of the sliding groove and the sliding frame.

[0010] Furthermore, the reset mechanism includes a movable frame slidably connected above the interior of the device body, and the upper part of the movable frame is exposed outside the device body. The lower part of the movable frame corresponds to the upper part of the sliding frame. The reset mechanism further includes a limit block fixedly connected to the movable frame. A fourth spring is sleeved outside the movable frame, and both ends of the fourth spring are fixedly connected to the top inner wall of the device body and the limit block respectively. When it is necessary to reset the inner sliding seat, the drill chuck and the drill bit, press the movable frame to make the sliding frame move downward in the chute outside the inner sliding seat. The sliding block and the clamping block on the inner side of the sliding frame are misaligned with the third spring and the sliding rod, and pressing the drill bit in the front can reset it.

[0011] Furthermore, the reciprocating mechanism includes a worm and a worm gear rotatably connected inside the device body, and the worm is meshed with the worm gear. The reciprocating mechanism further includes a transmission rod fixedly connected to the other output end of the double-headed motor, and the transmission rod is slidably connected to the worm. When the double-headed motor is driven, the worm is driven to rotate through the transmission rod, and then the worm gear is driven to rotate slowly through the meshing of the worm and the worm gear. The reciprocating mechanism further includes a sector gear fixedly connected to the outside of the worm gear, and a movable ring sleeved outside the sector gear. The movable ring is horizontally slidably connected inside the device body. Tooth grooves corresponding to the external teeth of the sector gear are respectively provided above and below the inside of the movable ring. The movable ring is fixedly connected to the sliding rod. When the worm gear rotates, it drives the sector gear to rotate, and the sector gear meshes back and forth with the tooth grooves above and below the inside of the movable ring, thereby driving the movable ring and the sliding rod to move horizontally back and forth.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] A hole punching device for a building wall provided by the present invention has a front positioning post at the front end of the device body. Before punching, the operator fits the front positioning post against the precast wall to avoid shaking, providing accurate positioning for punching. When the reciprocating mechanism drives the sliding rod to move, through the cooperation of the card slot and the clamping block, the gradual advancement of the drill bit is realized. Compared with manual hole punching, the work efficiency is high and the precision is high. When the drill bit encounters resistance during the punching process, such as hard objects inside the wall, the second spring between the inner sliding seat and the inner wall of the device body plays a buffering role, enabling the inner sliding seat to bounce back a certain distance outward, effectively preventing the drill bit from getting stuck due to excessive resistance, and preventing the device from being damaged due to the low rotation speed caused by the obstruction of the drill bit. It is similar to the flexible response method of pulling out and inserting the drill bit in time according to the state of the drill bit in manual operation, enhancing the adaptability of the device in a complex hole punching environment.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] To solve the technical problem that the existing manual hole punching has insufficient accuracy, as Figures 1-7 shown, the following preferred technical solutions are provided:

[0024] A drilling device for building walls, comprising a device main body 1, a double-headed motor 2, a speed regulator 3 and a drill chuck 4 arranged inside the device main body 1. An inner sliding seat 15 is slidably arranged inside the device main body 1. The double-headed motor 2 and the speed regulator 3 are installed inside the inner sliding seat 15. A plurality of second springs 16 are evenly distributed between one side of the inner sliding seat 15 and the inner wall of the device main body 1. One output end of the double-headed motor 2 is connected to one end of the speed regulator 3. The drill chuck 4 is connected to the other end of the speed regulator 3 and extends to the outside of the device main body 1. A reciprocating mechanism 5 is further arranged inside the device main body 1, and the reciprocating mechanism 5 is connected to the other output end of the double-headed motor 2. An adjusting mechanism 6 is arranged between the reciprocating mechanism 5 and the inner sliding seat 15. As Figure 6 shown, the adjusting mechanism 6 includes a sliding rod 61 connected to the reciprocating mechanism 5. A plurality of card slots 611 are evenly distributed inside the sliding rod 61. The adjusting mechanism 6 further includes a sliding frame 62 movably connected to the inner sliding seat 15. A sliding groove 621 is arranged inside the sliding frame 62. A sliding block 63 is slidably connected inside the sliding groove 621. A clamping block 64 corresponding to the card slot 611 is movably arranged inside the sliding block 63. A third spring 65 is arranged between the clamping block 64 and the inner wall of the sliding block 63.

[0025] As Figure 6 shown, the reciprocating mechanism 5 is configured such that the range of each reciprocating motion is the distance between two card slots 611; as Figure 6 and Figure 7 shown, the sliding range of the sliding block 63 is the length of one card slot 611. When the reciprocating mechanism 5 drives the sliding rod 61 to move in the drilling direction, moving a distance of two card slots 611, the sliding block 63 moves to the rightmost position inside the sliding groove 621. Subsequently, the sliding frame 62 moves to the right by a length of one card slot 611. The inner sliding seat 15, the double-headed motor 2 and the speed regulator 3 inside the inner sliding seat 15, the drill chuck 4 and the drill bit all move to the right by a length of one card slot 611. Subsequently, when the reciprocating mechanism 5 drives the sliding rod 61 to reset to the left, moving a distance of two card slots 611, since the clamping block 64 is in close fit with the card slot 611, when the sliding rod 61 resets, it will first drive the clamping block 64 and the sliding block 63 to reset to the left. When the sliding block 63 moves to the leftmost position inside the sliding groove 621 and cannot move further, the clamping block 64 will compress the third spring 65 and retract into the sliding block 63. At this time, since the sliding block 63 is located at the left side position inside the sliding groove 621, the inner sliding seat 15 has a certain range of movement, and the drill bit can bounce back a certain distance after being blocked.

[0026] As Figure 1As shown, an upper handle 11 and a lower handle 12 are respectively arranged at the top and bottom of the device main body 1, and a rear support 13 is installed at the tail of the device main body 1. The upper handle 11, the lower handle 12 and the rear support 13 are used for an operator to hold firmly. At the front end of the device main body 1, front positioning columns 14 are evenly distributed around the drill chuck 4. The front positioning columns 14 are used to fit the prefabricated wall surface of the drilled hole and play a positioning role.

[0027] As Figure 3 and Figure 6 shown, a chute 151 is provided on the outer wall of the inner sliding seat 15 close to the adjusting mechanism 6. The sliding frame 62 is slidably connected up and down inside the chute 151. A first spring 152 is installed between the lower part of the chute 151 and the sliding frame 62.

[0028] As Figure 1 and Figure 5 shown, the reset mechanism 7 includes a movable frame 71 slidably connected above the inside of the device main body 1, and the upper part of the movable frame 71 is exposed outside the device main body 1. The lower part of the movable frame 71 corresponds to the upper part of the sliding frame 62. The reset mechanism 7 further includes a limit block 72 fixedly connected to the movable frame 71. A fourth spring 73 is sleeved outside the movable frame 71. The two ends of the fourth spring 73 are respectively fixedly connected to the inner wall of the top of the device main body 1 and the limit block 72. When it is necessary to reset the inner sliding seat 15, the drill chuck 4 and the drill bit, press the movable frame 71 to make the sliding frame 62 move downward in the chute 151 outside the inner sliding seat 15. The sliding block 63 and the clamping block 64 on the inner side of the sliding frame 62 are displaced from the third spring 65 and the sliding rod 61. Press the drill bit in front to reset.

[0029] As Figure 5 shown, the reciprocating mechanism 5 includes a worm 51 and a worm gear 53 rotatably connected inside the device main body 1, and the worm 51 is meshed with the worm gear 53. The reciprocating mechanism 5 further includes a transmission rod 52 fixedly connected to the other output end of the double-headed motor 2, and the transmission rod 52 is slidably connected to the worm 51. When the double-headed motor 2 is driven, the worm 51 is driven to rotate through the transmission rod 52, and then the worm gear 53 is driven to rotate slowly through the meshing of the worm 51 and the worm gear 53. The reciprocating mechanism 5 further includes a sector gear 54 fixedly connected to the outside of the worm gear 53, and a movable ring 55 sleeved outside the sector gear 54. The movable ring 55 is slidably connected horizontally inside the device main body 1. Tooth grooves 56 corresponding to the external teeth of the sector gear 54 are respectively provided above and below the inside of the movable ring 55. The movable ring 55 is fixedly connected to the sliding rod 61. When the worm gear 53 rotates, the sector gear 54 is driven to rotate. The sector gear 54 meshes back and forth with the tooth grooves 56 above and below the inside of the movable ring 55, and thus the movable ring 55 and the sliding rod 61 can be driven to move horizontally back and forth.

[0030] Working principle:

[0031] The operator holds the upper handle 11 at the top of the equipment main body 1 and the lower handle 12 at the bottom, stably places the equipment in front of the precast wall, and makes the rear support 13 abut against the wall. At the same time, the front positioning column 14 located outside the drill chuck 4 at the front end of the equipment main body 1 fits against the precast wall, playing a positioning role to ensure the accuracy of the drilling position;

[0032] Start the double-headed motor 2. One output end of it is connected to the speed regulator 3, which can adjust the output speed of the motor. The drill chuck 4 connected to the other end of the speed regulator 3 drives the drill bit to start rotating. At the same time, the other output end of the double-headed motor 2 drives the transmission rod 52, and the transmission rod 52 drives the worm 51 connected to it in a sliding manner to rotate; The worm 51 meshes with the worm gear 53, driving the worm gear 53 to rotate slowly; The sector gear 54 fixed to the outside of the worm gear 53 rotates accordingly. The sector gear 54 meshes with the tooth grooves 56 up and down inside the movable ring 55, driving the movable ring 55 and the sliding rod 61 fixedly connected to it to move horizontally back and forth;

[0033] The reciprocating mechanism 5 moves back and forth within the distance of two card slots 611 each time. When the sliding rod 61 moves two card slot 611 distances in the drilling direction, the sliding block 63 moves to the rightmost position in the sliding slot 621. Subsequently, the sliding frame 62 drives the inner sliding seat 15 and the double-headed motor 2, speed regulator 3, drill chuck 4 and drill bit inside to move to the right by the length of one card slot 611, realizing the advancement of the drill bit. When the reciprocating mechanism 5 drives the sliding rod 61 to reset to the left, the sliding rod 61 first drives the block 64 and the sliding block 63 to reset to the left. When the sliding block 63 moves to the leftmost position in the sliding slot 621 and cannot move further, the block 64 compresses the third spring 65 and retracts into the sliding block 63. When the drill bit encounters an obstacle, such as a hard object inside the wall, the second spring 16 between the inner sliding seat 15 and the inner wall of the equipment main body 1 plays a role, enabling the inner sliding seat 15 to bounce back a certain distance outward, avoiding damage to the drill bit and the equipment. At this time, the inner sliding seat 15 can move, and the drill bit can bounce back;

[0034] When it is necessary to reset the inner sliding seat 15, drill chuck 4 and drill bit, press the movable frame 71 exposed outside the equipment main body 1 in the reset mechanism 7. The lower part of the movable frame 71 corresponds to the upper part of the sliding frame 62. Press the movable frame 71 to make the sliding frame 62 move downward in the sliding groove 151 outside the inner sliding seat 15. The sliding block 63, block 64 and the third spring 65 inside the sliding frame 62 are misaligned with the sliding rod 61. At this time, pressing the drill bit in front can achieve reset. The limit block 72 and the sleeved fourth spring 73 on the movable frame 71 play a role in assisting reset and limiting;
