Description

Technical Field

[0001] The invention relates to the technical field of metal door processing, in particular to a drilling device for metal door processing which is easy to adjust. Background Art

[0002] In modern industrial production, metal doors are important components for building safety and decoration. The precision and efficiency of their processing and manufacturing have a direct impact on product quality and production efficiency. Drilling is one of the key processes in the metal door processing process. It is used to install door locks, hinges and other components. The accuracy of the hole position, the precision of the hole diameter and the efficiency of drilling are directly related to the overall quality and assembly effect of the metal door.

[0003] Traditional metal door drilling equipment has numerous practical problems. Some equipment uses simple conveyor belts for transporting metal doors, lacking effective positioning and guiding devices. This can cause the metal doors to shift and slide during transport, making it difficult to accurately reach the designated processing position. This not only affects processing efficiency but can also lead to incorrect drilling positions due to positional deviations, resulting in waste.

[0004] The fixing devices of traditional equipment are often simple in structure and single in function, and are difficult to adapt to metal doors of different sizes. For metal doors with irregular shapes or large size differences, stable clamping cannot be achieved. At the same time, the rigid clamping method adopted by some equipment can easily cause indentations, scratches and other damage to the surface of the metal door during the clamping process, affecting the appearance quality and performance of the metal door. Summary of the Invention

[0020] 1. The drilling equipment for metal door processing which is easy to adjust, has a fixed adjusting mechanism. When the metal door is transported to the bottom of the fixed adjusting mechanism, the metal door squeezes the plywood, and the elastic telescopic rod is compressed by force, so that the plywood can adaptively fit the surface of the metal door. The second cylinder is started, and the second telescopic rod pushes the slider to slide in the strip-shaped through hole, driving the plywood and the metal door to move to the drilling position. During the movement of the plywood, the plywood squeezes the fixed pressure block, and the slide bar slides on the top of the C-shaped right-angle plate.

The elastic telescopic rod enables the plywood to be adaptively adjusted according to the surface shape of the metal door to ensure the clamping effect. The fixed pressure block in the fixing part automatically adjusts its position and applies pressure when the plywood moves, thereby further enhancing the fixation of the metal door.

[0021] 2. The drilling equipment for metal door processing which is easy to adjust, through the setting of the drilling mechanism, supplies a motor to drive the screw to rotate, and the drilling part connected to the screw through the threaded hole transmission moves horizontally along the screw with the cooperation of the slide rail and the slide groove 2 to reach the horizontal position of the required drilling, starts the cylinder 1, and the telescopic rod 1 drives the lifting frame to descend along the guide rail, so that the drill bit of the drilling part approaches the metal door.

The drilling motor provides power to make the drill bit rotate at high speed to complete the drilling operation. The protective cover protects the drilling motor and other components from processing debris, thereby extending the service life of the equipment and reducing the maintenance cost of the equipment.

[0022] 3. This drilling equipment for metal door processing is easy to adjust. Through the setting of the conveying mechanism, the operator places the metal door on the conveyor belt and starts the conveying motor. The conveying motor drives the transmission shaft to rotate, and then the conveyor roller rotates, driving the conveyor belt to run. The anti-slip strip on the outer surface of the conveyor belt contacts the metal door, and the metal door is driven forward by the action of friction. The supporting roller provides support for the conveyor belt to ensure the smooth operation of the conveyor belt. The conveying mechanism ensures that the metal door can be transported to the designated position quickly and stably, thereby improving the continuity and efficiency of the processing.

[0023] 4. The drilling equipment for metal door processing that is easy to adjust, by adjusting the setting of the positioning mechanism, when the metal door is placed on the conveyor belt for transportation, the positioning block in the positioning mechanism is adjusted to slide along the guide rod in the slide groove on the outer surface of the rotating column under the elastic force of the positioning spring, and the positioning block cooperates with the arc-shaped guide piece to accurately locate and guide the position of the metal door on the conveyor belt. The positioning block adjusts the contact position with the metal door through elastic expansion and contraction, ensuring that the metal door is in the correct transportation path on the conveyor belt, ensuring that the metal door will not deviate or skew during transportation, and improving the accuracy and stability of the metal door during transportation and subsequent processing.

[0024] 5. The drilling equipment for processing metal doors that is easy to adjust is arranged by cooperating with the curved belt pressing plate and the fixed adjustment mechanism. When the metal door is conveyed by the conveyor belt and passes through the curved belt pressing plate, the curved belt pressing plate guides the metal door and guides the metal door to move toward the fixed adjustment mechanism. When the metal door reaches the bottom of the fixed adjustment mechanism, the clamping plate of the fixed adjustment mechanism clamps and fixes the metal door under the action of the elastic telescopic rod and the second cylinder. The curved belt pressing plate uses its curved structure to guide the conveying direction of the metal door, so that the metal door can accurately enter the working area of ​​the fixed adjustment mechanism, thereby improving processing efficiency.

A conveyor belt 24 is transmission-mounted on the outer surface of the conveyor roller 23. The conveyor roller 23 supports the conveyor belt 24 and drives it to move, thereby realizing the conveyance of the metal door. An anti-slip strip 25 is fixedly mounted on the outer surface of the conveyor belt 24. The anti-slip strip 25 increases the friction between the conveyor belt 24 and the metal door to prevent the metal door from sliding during the conveying process.

[0040] The inner side of the conveyor belt 24 is provided with a supporting roller 26, which is rotatably mounted inside the frame 1 through a rotating shaft. The supporting roller 26 is arranged at both ends of the arc-shaped belt pressing plate 4. The supporting roller 26 supports the conveyor belt 24 to ensure smooth transportation.

A positioning block 275 is slidably mounted on the outer surface of the guide rod 274, and a pad 276 is fixedly mounted on the end of the positioning block 275. A positioning spring 277 is fixedly connected between the positioning block 275 and the inner wall of the sliding groove 273. The positioning spring 277 is arranged on the outer surface of the guide rod 274. Through the sliding of the positioning block 275 in the sliding groove 273 and the elastic action of the positioning spring 277, the position of the metal door is preliminarily positioned so that it accurately enters the fixed adjusting mechanism 6;

[0043] There are twelve chute 1s 273 evenly distributed along the axis of the rotating column 272. Curved guides 278 are fixedly mounted on both sides of the outer surface of the rotating column 272. The curved guides 278 are spaced apart from the chute 1s 273. The curved guides 278 and the positioning blocks 275 are both arranged on both sides of the conveyor belt 24. The curved guides 278 serve to guide and assist in positioning.

[0044] The drilling mechanism 5 is installed at the top of the inner cavity of the mounting shell 3, and the drilling mechanism 5 realizes drilling holes at different positions of the metal door;

[0045] The fixed adjustment mechanism 6 is installed on both sides of the frame 1. The fixed adjustment mechanism 6 is arranged directly above the arc-shaped belt pressing plate 4. The arc-shaped belt pressing plate 4 cooperates with the fixed adjustment mechanism 6. The arc-shaped belt pressing plate 4 plays a guiding role, guiding the metal door on the conveying mechanism 2 to the fixed adjustment mechanism 6. The fixed adjustment mechanism 6 clamps and fixes the metal door. The fixed adjustment mechanism 6 automatically adjusts the clamping force during the drilling process, and transports the metal door to the conveying mechanism 2 for transportation after the drilling is completed.

[0046] The second embodiment, based on the first embodiment, see Figure 7 and Figure 8As shown, the fixed adjustment mechanism 6 includes a C-shaped right-angle plate 61 and a second cylinder 62. The C-shaped right-angle plate 61 is installed on the side of the frame 1, and the second cylinder 62 is fixedly installed on the outer surface of the frame 1. A strip through-hole 64 is opened on the surface of the C-shaped right-angle plate 61. The telescopic end of the second cylinder 62 is fixedly connected to the second telescopic rod 63.

[0049] The third embodiment, based on the first and second embodiments, see Figure 9 and Figure 10As shown, the drilling mechanism 5 includes a cylinder 51, which is fixedly mounted on the top of the mounting shell 3, and a telescopic end of the cylinder 51 is fixedly connected to a telescopic rod 52, which penetrates the mounting shell 3 and extends into the interior thereof, and a lifting frame 53 is fixedly mounted on the bottom of the telescopic rod 52, and the lifting frame 53 is slidably mounted on the outer surface of the guide rail 7, and a second slide groove 57 is provided on the surface of the lifting frame 53, and a supply motor 55 is fixedly mounted on one side of the lifting frame 53 through a bracket, and a screw rod 56 is fixedly connected to the output end of the supply motor 55, and a drilling member 54 is transmission-mounted on the outer surface of the screw rod 56, and the drilling member 54 is slidably mounted inside the second slide groove 57. The cylinder 51 drives the telescopic rod 52 to drive the lifting frame 53 to perform lifting and lowering movements on the guide rail 7, thereby adjusting the height of the drilling member 54, and the supply motor 55 drives the drilling member 54 to move horizontally in the second slide groove 57 through the screw rod 56, so as to realize drilling of different positions of the metal door;

[0050] The drilling member 54 includes a mounting block 541 and a drilling motor 545. A slide rail 543 is fixedly mounted on the side of the mounting block 541. The slide rail 543 is slidably mounted inside the second slide groove 57. A threaded hole 542 is opened in the middle of the mounting block 541. The mounting block 541 is driven and mounted on the outer surface of the screw rod 56 through the threaded hole 542. A protective cover 544 is fixedly mounted on the bottom of the mounting block 541. The drilling motor 545 is fixedly mounted on the bottom of the inner cavity of the protective cover 544 through a bracket. The output end of the drilling motor 545 is fixed to the bottom of the inner cavity of the protective cover 544. A rotating shaft 546 is fixedly connected, and the rotating shaft 546 passes through the protective cover 544 and extends to its bottom. A clamp 547 is fixedly installed on the bottom of the rotating shaft 546, and a drill bit 548 is fixedly installed on the bottom of the clamp 547. The mounting block 541 is connected to the screw rod 56 through the threaded hole 542, and slides in the slide groove 57 through the slide rail 543. The protective cover 544 protects the drilling motor 545 and other components. The drilling motor 545 drives the rotating shaft 546 to drive the clamp 547 and the drill bit 548 to rotate, so as to drill holes in the metal door.

[0051] During use, the operator places the metal door to be drilled on the conveyor belt 24 of the conveying mechanism 2, starts the conveying motor 21, drives the transmission shaft 22 to rotate, and then rotates the conveying roller 23, drives the conveyor belt 24 to run, and conveys the metal door. The metal door is positioned by the adjustment and positioning mechanism 27, guided by the arc-shaped belt pressing plate 4, and transported to the fixed adjustment mechanism 6;

[0052] The positioning blocks 275 in the adjustment and positioning mechanisms 27 on both sides of the frame 1 slide along the guide rods 274 in the slide slots 273 under the action of the positioning springs 277, thereby positioning and guiding the metal door. The arc-shaped guide pieces 278 also assist in the transportation of the metal door.

[0053] When the metal door is transported to the fixed adjustment mechanism 6, the metal door squeezes the clamping plate 67. Under the elastic force of the elastic telescopic rod 66, the clamping plate 67 adaptively clamps the metal door. The second cylinder 62 is activated, and the second telescopic rod 63 pushes the slider 65 to slide in the strip-shaped through hole 64, so that the clamping plate 67 drives the metal door to the drilling position. The buffer pad 68 on the clamping plate 67 contacts the metal door to play a protective role.

[0054] When the clamping plate 67 conveys the metal door, the clamping plate 67 squeezes the fixed pressing block 693 so that it presses the slide bar 691 downward, causing the fixed pressing block 693 to squeeze the clamping plate 67. The slide bar 691 slides on the top of the C-shaped right-angle plate 61. The fixed pressing block 693 that is not in contact with the fixed pressing block 693 further fixes the metal door. The fixing spring 694 provides elastic force to ensure the fixing effect.

[0055] Start the supply motor 55, which drives the screw 56 to rotate, so that the drilling member 54 moves along the screw 56 in the slide groove 2 57 to a suitable horizontal position. The cylinder 1 51 drives the telescopic rod 1 52 to drive the lifting frame 53 to descend along the guide rail 7, so that the drill bit 548 approaches the metal door. The drilling motor 545 drives the rotating shaft 546 to drive the clamp 547 and the drill bit 548 to rotate, and drill the metal door.

[0056] After the drilling is completed, the cylinder 1 51 drives the lifting frame 53 to rise and reset, the supply motor 55 drives the drilling part 54 back to the initial position, and the cylinder 2 62 drives the splint 67 to transport the metal door, so that it enters the conveying mechanism 2 for further transportation, completing the entire processing process.
