[0002] The appearance of existing steel doors is similar to that of wood, iron and aluminum alloy doors, but steel doors have higher impact resistance than wood, iron and aluminum alloy doors. In particular, when used as a gate, the rust resistance of the steel door itself increases its service life. At present, an important process in the production process of stainless steel doors is to drill holes on the surface of the steel door in order to install hinges and connect them to the door frame, thereby realizing the opening and closing of the steel door.

[0003] At present, when steel doors are processed and produced, it is necessary to drill holes in the doors and windows to facilitate the installation of parts.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] See also Figure 1-9 , the present invention provides a technical solution:

[0037] A steel door drilling device comprises a first bracket 1 and a second bracket 5, wherein a spacing adjustment component is arranged between the first bracket 1 and the second bracket 5;

[0038] The spacing adjustment assembly includes a support frame 4 disposed between the first bracket 1 and the second bracket 5, and the support frame 4 is used to place the steel door 2, and a plurality of telescopic rods 18 are slidably connected inside the two sides of the support frame 4, and the first bracket 1 and the second bracket 5 are fixedly connected to the support frame 4 through the plurality of telescopic rods 18;

[0039] A groove 13 is formed at one end of the second bracket 5, a bidirectional threaded rod 14 is rotatably connected to the inner cavity of the groove 13, and two sliders 15 are externally threadedly connected to the bidirectional threaded rod 14, one end of each of the two sliders 15 is fixedly connected to a synchronous push rod 16, an upper end of the synchronous push rod 16 is fixedly connected to an L-shaped bracket 17, and a triangular fixing frame 10 is installed on one side of the upper end of the L-shaped bracket 17, and two drill bits 30 are symmetrically installed at the lower end of the triangular fixing frame 10;

[0040] The lower end surfaces of the first bracket 1 and the second bracket 5 are fixedly connected with supporting feet 9 at four corners, and the lower ends of the supporting feet 9 are equipped with universal wheels 3.

[0041] Specifically, in the prior art, due to the different sizes of steel doors, it is necessary to adjust the position of the drilling machine when drilling holes in the steel doors. The drilling machine is generally installed with the piston rod of the electric push rod, so that the piston rod of the electric push rod can be used to push the drilling machine downward to achieve drilling. Therefore, the position of the electric push rod needs to be adjusted when drilling holes. However, after the electric push rod has adjusted its position, if the electric push rod is not limited and fixed, it is difficult to ensure the stability of the position of the drilling machine, resulting in the drilling machine being difficult to bear force when drilling holes in the steel door, affecting the drilling efficiency of the steel door;

[0042] When drilling a hole in the steel door 2, the present invention transports the steel door 2 to the support frame 4 through an external transport device, and at the same time drives the telescopic rod 18 to slide into the inner cavity of the support frame 4, and the telescopic rod 18 drives the first bracket 1 and the second bracket 5 to move closer to each other. In the process of the first bracket 1 and the second bracket 5 moving closer to each other, the supporting foot 9 is driven to move synchronously, and the universal wheel 3 is used to move closer to each other, so that the first bracket 1 and the second bracket 5 can clamp and fix the steel door 2 on the support frame 4, and then the bidirectional threaded rod 14 is driven to rotate, and the bidirectional threaded rod 14 is threaded to drive the two sliders 15 to move closer to each other. The synchronous push rod 16 moves synchronously, and during the movement of the synchronous push rod 16, the L-shaped bracket 17 moves closer to each other, and the triangular fixing frame 10 moves synchronously, and then the drill bit 30 is driven to move and adjust the drilling position, and then the drill bit 30 is driven to rotate, and the drill bit 30 drills the steel door 2 at the same time, thereby solving the problem that the existing steel door drilling device cannot adjust the position of the drill machine at will due to the different sizes of the steel doors when drilling the steel doors, and at the same time ensures the stability of the position of the drill machine, resulting in the drill machine being difficult to bear force when drilling the steel door, affecting the drilling efficiency of the steel door.

[0043] like Figure 3 to Figure 4 As shown, a transmission shaft 20 is rotatably connected to the inner cavity of the support frame 4, and one end of the transmission shaft 20 that passes through the support frame 4 is fixedly connected to a crank 12, and three transmission bevel gears 21 are fixedly connected to the outside of the transmission shaft 20, and the outsides of the three transmission bevel gears 21 are all meshedly connected to driven bevel gears 22, and the driven bevel gears 22 are fixedly connected to the inside of a threaded rod 23, and a threaded groove 19 is provided inside the telescopic rod 18, and the threaded rod 23 is threadedly connected to the threaded groove 19.

[0044] Specifically, when drilling a hole in the steel door 2, the steel door 2 is transported to the support frame 4 through an external conveying device, and the crank 12 is driven to rotate, and the crank 12 drives the transmission shaft 20 to rotate, and then drives the transmission bevel gear 21 to rotate. During the rotation process, the transmission bevel gear 21 will engage the driven bevel gear 22 to rotate, and the driven bevel gear 22 will drive the threaded rod 23 to rotate. At the same time, the threaded rod 23 cooperates with the threaded groove 19 to slide the threaded transmission telescopic rod 18 in the inner cavity of the support frame 4, and then drives the first bracket 1 and the second bracket 5 to move closer to each other, so as to clamp and fix the steel door 2 above the support frame 4 and improve the drilling accuracy. Then, the telescopic rod 18 is driven to drive the first bracket 1 and the second bracket 5 to move closer to each other, so that the first bracket 1 and the second bracket 5 can clamp and fix the steel door 2 on the support frame 4, thereby preventing the steel door from moving due to the force of the drill bit pressing down to punch a hole when drilling a hole in the steel door 2.

[0045] like Figure 2 , Figure 4 and Figure 7 As shown, one side of the synchronous push rod 16 is fixedly connected to the limit baffle 7, a stop block 8 is installed in the middle of one end of the second bracket 5, a driving motor is arranged inside one side of the second bracket 5, and the output shaft of the driving motor is fixedly connected to the bidirectional threaded rod 14.

[0046] Specifically, in the process of driving the synchronous push rods 16 to move closer to each other, the synchronous push rods 16 will drive the limit baffle 7 to move synchronously, and then the limit baffle 7 can be used to abut the two ends of the steel door 2 above the support frame 4. As the synchronous push rods 16 continue to move closer to each other, the limit baffle 7 can clamp and position the two ends of the steel door 2. At this time, the driving of the synchronous push rods 16 to move closer to each other is stopped, and then the synchronous push rods 16 are started to drive the drill bit 30 to move downward, and at the same time drive the drill bit 30 to drill the steel door 2, thereby solving the problem that when the existing steel door drilling device is used to drill steel doors of different sizes, the drilling position of the drilling device needs to be adjusted, resulting in too slow drilling efficiency, affecting the production efficiency of the steel door.

[0047] like Figure 2 , Figure 6 and Figure 7 As shown, a servo motor 24 is disposed inside the upper end of the tripod fixing frame 10 , and the servo motor 24 is fixedly connected to a first sprocket 25 via an output shaft. The first sprocket 25 is externally connected to a chain 27 , and one end of the chain 27 is internally connected to a second sprocket 26 .

[0048] Specifically, after the steel door 2 on the support frame 4 is clamped and positioned, the servo motor 24 is started to drive the first sprocket 25 to rotate, and at the same time, the first sprocket 25 drives the transmission sprocket 27 to rotate, and then drives the second sprocket 26 to rotate, and then the second sprocket 26 drives the drill bit 30 to rotate to drill the steel door 2, thereby improving the drilling efficiency of the steel door.

[0049] like Figure 2 , Figures 5 to 7 As shown, a third sprocket 28 is connected to one end of the chain 27 in a transmission manner, a rotating column 29 is fixed to the lower end surfaces of the second sprocket 26 and the third sprocket 28, and the rotating column 29 is rotatably connected to the triangular fixing frame 10, and the lower end of the rotating column 29 is used to install a drill bit 30.

[0050] Specifically, after the steel door 2 on the support frame 4 is clamped and positioned, the chain 27 is driven to rotate, and at the same time, the chain 27 drives the second sprocket 26 and the third sprocket 28 to rotate. During the rotation process, the second sprocket 26 and the third sprocket 28 will drive the rotating column 29 to rotate. Since a drill bit 30 is installed inside the lower end of the rotating column 29, the drill bit 30 will be driven to rotate synchronously, thereby drilling holes in the steel door 2, avoiding the problem that when drilling holes in the existing steel door drilling device, four holes need to be drilled symmetrically on both sides of the steel door for installing hinges, but the existing drilling device can only drill holes one by one, resulting in slow drilling efficiency and deviations in the drilled holes.

[0051] like Figure 2 , Figures 5 to 7 As shown, a receiving groove 31 is provided on the lower end surface of the triangular fixing frame 10, a spring 32 is fixedly connected to the bottom of the inner cavity of the receiving groove 31, a T-shaped slide bar 33 is fixedly connected to the lower end of the spring 32, a pressing plate 34 is fixedly connected to the lower end of the T-shaped slide bar 33, cleaning holes 36 are provided on both sides of the lower end surface of the pressing plate 34, and brushes are evenly arranged on the inner cavity wall of the cleaning hole 36.

[0052] Specifically, when drilling a hole in the steel door 2, the triangular fixing frame 10 is driven to move downward, and the triangular fixing frame 10 drives the T-shaped slide bar 33 to move downward, and the T-shaped slide bar 33 pushes the pressing plate 34 to move downward. The pressing plate 34 can be installed with a rubber anti-skid pad at the lower end of the pressing plate 34 according to actual usage, and then the steel door 2 on the support frame 4 is pressed and fixed when the pressing plate 34 moves downward. As the triangular fixing frame 10 continues to move downward, the pressing force of the pressing plate 34 on the steel door 2 is increased, and the pressing plate 34 pushes the T-shaped slide bar 33 to move upward, and the T-shaped slide bar 33 slides into the inner cavity of the storage groove 31 and squeezes the spring 32 in the inner cavity of the storage groove 31, and then the drill bit 30 slides out of the cleaning hole 36 to drill the steel door 2. After the drilling is completed, the tripod fixing frame 10 is driven to move upward and reset, and then the spring 32 in the inner cavity of the storage groove 31 is used to pop up the T-shaped slide bar 33, and the T-shaped slide bar 33 pushes the pressing plate 34 to move downward, and then the brush on the inner wall of the cleaning hole 36 is used to clean and scrape the filamentary debris generated by drilling on the surface of the drill bit 30, thereby solving the problem that when the existing steel door drilling device is drilling a steel door, the waste chips drilled by the drill bit will be in the shape of filaments, long, and will be entangled on the outside of the drill bit. If it is not scraped and cleaned, a large amount of filamentary waste chips will be entangled on the outside of the drill bit, and a large amount of heat will be generated during the high-speed rotation drilling process of the drill bit. The entangled filamentary waste chips will hinder the normal dissipation of heat, causing the drill bit temperature to rise rapidly, thereby reducing the hardness and durability of the drill bit.

[0053] Embodiment 2

[0054] like Figures 1 to 9As shown in Comparative Example 1, another embodiment of the present invention is:

[0055] like Figure 1 and Figure 8 As shown, a flip limit assembly 6 is provided at one end of the first bracket 1, and the flip limit assembly 6 includes a U-shaped support block 61 fixedly connected to one end of the first bracket 1, the inner cavity of the U-shaped support block 61 is rotatably connected to a rotating block 66, and a plurality of fixed blocks 67 are evenly fixed to the outside of the rotating block 66, and rotating shafts 65 are fixedly connected at both ends of the rotating block 66, and the rotating shaft 65 is rotatably connected to the U-shaped support block 61.

[0056] Specifically, when drilling the steel door 2, the steel door 2 is transported to the support frame 4 through an external transporting device. When the steel door 2 is transported to the support frame 4, the steel door 2 will push the fixed block 67 to rotate, and at the same time, the fixed block 67 drives the rotating block 66 to rotate, and then drives the rotating shaft 65 to rotate. After the steel door 2 is completely pushed onto the support frame 4, the fixed block 67 will resist the steel door 2 on the support frame 4, so that when the steel door 2 on the support frame 4 is clamped and positioned, the fixed block 67 can be used to abut and clamp the steel door 2.

[0057] like Figure 1 and Figure 8 As shown, a transmission groove 69 is provided inside the U-shaped support block 61, a rotating shaft 65 is located outside the inner cavity of the transmission groove 69 and is fixedly connected to a ratchet 68, a T-shaped slide groove 62 is provided on the inner cavity wall of the transmission groove 69, a micro spring 63 is fixedly connected to the bottom of the inner cavity of the T-shaped slide groove 62, one end of the micro spring 63 is fixedly connected to a T-shaped tooth block 64, the T-shaped tooth block 64 is meshed with the ratchet 68, and one end of the T-shaped tooth block 64 is set to an arc surface.

[0058] Specifically, when drilling the steel door 2, the steel door 2 is transported to the support frame 4 through an external transport device. When the steel door 2 is transported to the support frame 4, the steel door 2 will push the fixed block 67 to rotate, and the fixed block 67 drives the rotating block 66 to rotate, and then drives the rotating shaft 65 to rotate. During the rotation of the rotating shaft 65, the rotating shaft 65 will be driven to rotate, and the ratchet 68 will be driven to rotate. During the rotation of the ratchet 68, the arc surface of the T-shaped tooth block 64 will be squeezed, so that the T-shaped tooth block 64 slides into the inner cavity of the T-shaped slide groove 62, and squeezes the micro spring 63 in the inner cavity of the T-shaped slide groove 62, and the steel door 2 is completely pushed After reaching the support frame 4, the micro spring 63 in the inner cavity of the T-shaped slide groove 62 will pop up the T-shaped tooth block 64, and at the same time, the T-shaped tooth block 64 will be inserted into the inner cavity of the ratchet 68, and then the ratchet 68 will be engaged and limited, thereby preventing the fixed block 67 from rotating. Then, when driving the first bracket 1 and the second bracket 5 to move closer to each other, the fixed block 67 can be used to cooperate with the abutment block 8 to clamp and fix the steel door 2, thereby solving the problem that when the existing steel door drilling device is drilling holes on the steel door, due to the different sizes of the steel door, if it is not clamped and positioned, it will cause the steel door to be pressed down by the drill bit to drill holes, resulting in movement and affecting the drilling accuracy.

[0059] like Figure 1 , Figure 5 and Fig. 9 As shown, a U-shaped fixing block 35 is fixedly connected to one end of the triangular fixing frame 10, and a T-shaped flip frame 11 is rotatably connected to the inner cavity of the U-shaped fixing block 35, and the T-shaped flip frame 11 is located outside the inner cavity of the U-shaped fixing block 35 and is fixedly connected to a fixing plate 38, brushes are evenly arranged on one end of the T-shaped flip frame 11, a torsion spring 37 is fixedly connected to the inner cavity of the U-shaped fixing block 35, and one end of the torsion spring 37 is fixedly connected to the fixing plate 38.

[0060] Specifically, when the triangular fixing frame 10 is driven to move downward, the triangular fixing frame 10 will drive the U-shaped fixing block 35 to move downward, and the U-shaped fixing block 35 will drive the T-shaped flip frame 11 to move downward. During the downward movement of the triangular fixing frame 10, the T-shaped flip frame 11 will contact the steel door 2 on the support frame 4 in advance. As the triangular fixing frame 10 continues to move downward, the T-shaped flip frame 11 is subjected to the downward pressure of the triangular fixing frame 10, which will drive the fixing plate 38 to rotate and twist the torsion spring 37 to rotate. At this time, the downward movement of the triangular fixing frame 10 will drill holes in the steel door 2, and drilling holes in the steel door After the processing is completed, the triangular fixing frame 10 is driven to move upward. At this time, the torsion spring 37 rotates and resets, and drives the fixing plate 38 to rotate. At the same time, the fixing plate 38 drives the T-shaped flip frame 11 to rotate, and then the brush at one end of the T-shaped flip frame 11 is used to clean the debris and filamentary waste generated by drilling the steel door 2, thereby solving the problem that the existing steel door drilling device will generate a large amount of debris and filamentary waste when drilling the steel door. After the drilling is completed, if the debris and filamentary waste generated by the drilling of the steel door are not cleaned, it will cause the later installers to waste a lot of time to clean the debris and filamentary waste at the drilling site.

[0061] Working principle: when drilling a hole in the steel door 2, the steel door 2 is transported to the support frame 4 through an external transport device, and the telescopic rod 18 is driven to slide into the inner cavity of the support frame 4, and the telescopic rod 18 drives the first bracket 1 and the second bracket 5 to move closer to each other. In the process of the first bracket 1 and the second bracket 5 moving closer to each other, the supporting foot seat 9 is driven to move synchronously, and the universal wheel 3 is used to move closer to each other, so that the first bracket 1 and the second bracket 5 can clamp and fix the steel door 2 on the support frame 4, and then the two-way threaded rod 14 is driven to rotate, and the two-way threaded rod 14 is threaded to drive the two sliders 15 to move closer to each other, and the synchronous push rod 16 is driven to move synchronously. In the process of moving, the synchronous push rod 16 will drive the L-shaped bracket 17 to move closer to each other, and drive the triangular fixing frame 10 to move synchronously, and then the drill bit 30 can be driven to move and adjust the drilling position, and then the drill bit 30 is driven to rotate, and the drill bit 30 is driven to drill the steel door 2 at the same time;

[0062] When drilling a hole in the steel door 2, the triangular fixing frame 10 is driven to move downward, and the triangular fixing frame 10 drives the T-shaped slide bar 33 to move downward, and the T-shaped slide bar 33 pushes the pressing plate 34 to move downward, and the pressing plate 34 can be installed with a rubber anti-skid pad at the lower end of the pressing plate 34 according to actual use conditions, so that when the pressing plate 34 moves downward, the steel door 2 on the support frame 4 is pressed and fixed, and as the triangular fixing frame 10 continues to move downward, the pressing force of the pressing plate 34 on the steel door 2 is increased, and the pressing plate 34 pushes The T-shaped slide bar 33 moves upward, and the T-shaped slide bar 33 slides into the inner cavity of the storage groove 31, and squeezes the spring 32 in the inner cavity of the storage groove 31, and then the drill bit 30 slides out of the cleaning hole 36 to drill the steel door 2. After the drilling is completed, the triangular fixing frame 10 is driven to move upward to reset, and then the spring 32 in the inner cavity of the storage groove 31 is used to bounce the T-shaped slide bar 33, and the T-shaped slide bar 33 pushes the pressing plate 34 to move downward, and then the brush on the inner wall of the cleaning hole 36 is used to clean and scrape the filamentous debris generated by drilling on the surface of the drill bit 30;

[0063] When the triangular fixing frame 10 is driven to move downward, the triangular fixing frame 10 will drive the U-shaped fixing block 35 to move downward, and the U-shaped fixing block 35 will drive the T-shaped flip frame 11 to move downward. During the downward movement of the triangular fixing frame 10, the T-shaped flip frame 11 will contact the steel door 2 on the support frame 4 in advance. As the triangular fixing frame 10 continues to move downward, the T-shaped flip frame 11 is subjected to the downward pressure of the triangular fixing frame 10, which will drive the fixing plate 38 to rotate and twist the torsion spring 37 to rotate. At this time, the downward movement of the triangular fixing frame 10 will drill the steel door 2. After the drilling of the steel door is completed, the triangular fixing frame 10 is driven to move upward. At this time, the torsion spring 37 rotates and resets, and drives the fixing plate 38 to rotate. At the same time, the fixing plate 38 drives the T-shaped flip frame 11 to rotate, and then the brush at one end of the T-shaped flip frame 11 is used to clean the debris and filamentous waste generated by the drilling of the steel door 2.
