Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and in particular to a drilling equipment for door frame production. Background Technology

[0002] A door frame, also known as a door panel, is generally composed of two vertical side frames and a top frame. When the door has a transom, there is also a middle horizontal frame, and for multi-panel doors, there is also a middle vertical frame. The door frame is the connecting component between the door panel, transom, and the wall. Before installation, the door frame needs to be marked according to the size of different door panels. After marking, holes are drilled at the marked locations to facilitate the installation of the door panels on the door frame.

[0003] A search revealed a Chinese patent publication number CN210996621U, which discloses a high-precision drilling device for processing subway emergency door frame materials. The device includes a workbench with a support frame welded to its top. A cylinder is mounted on the top of the support frame. Fixing holes are provided on both sides of the support frame. Movable plates are slidably connected to the inner walls of the fixing holes. A drill rod is connected to one end of the motor output shaft. First sleeves are installed on both sides of the bottom end of the movable plate by screws. A second compression spring is welded to the top of the inner wall of the fixing groove. One end of each of the two connecting rods is welded to the outer ends of the positioning ring.

[0004] This patent allows for precise positioning of the drilling location by aligning the positioning ring with the desired drilling position before drilling, thus improving drilling accuracy and facilitating the smooth progress of subsequent work. However, after each drilling operation, the completed door frame must be removed before the next door frame can be installed, which wastes time and affects efficiency. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example 1

[0026] A drilling device for door frame production, such as Figures 1 to 3As shown, the workbench 1 has two guide grooves on its top outer wall. The same movable plate 2 is slidably fitted onto the inner walls of the two guide grooves. Two fixing components 3 are provided on the top outer wall of the movable plate 2. A fixing frame 5 is fixed to the top outer wall of the workbench 1. A telescopic rod 6 is installed on the top outer wall of the fixing frame 5. A first linear drive assembly 7 is fixedly connected to the telescopic end of the telescopic rod 6. The first linear drive assembly 7 includes a sliding frame, a lead screw, a drive motor, and a moving block. The moving block in the first linear drive assembly 7 is connected to a second linear drive assembly 8. The second linear drive assembly 8 has the same structure as the first linear drive assembly 7. A drill rod 9 driven by a drilling motor is installed at the bottom of the moving block of the second linear drive assembly 8. A fixing component 3 is located below the drill rod 9. A moving component 4 is installed in a guide groove. The moving component 4 includes a lead screw and a drive motor.

[0027] The fixing component 3 includes a fixing plate 11 and a positioning block 13. The fixing plate 11 is embedded in the top outer wall of the movable plate 2, and the positioning block 13 is fixed to the top outer wall of the fixing plate 11. A cavity 14 is opened inside the positioning block 13. A bearing plate 12 is slidably fitted on the outer wall of the positioning block 13, and the bearing plate 12 is slidably fitted with the inner wall of the cavity 14. A moving rod 15 is vertically slidably fitted at the bottom end of the movable plate 2. The top end of the moving rod 15 contacts the bearing plate 12. An annular protrusion is provided on the bottom outer wall of the moving rod 15. A spring 16 is sleeved on the outer wall of the moving rod 15. The two ends of the spring 16 are respectively connected to the annular protrusion and the movable plate 2. A sliding groove 10 is opened on the top outer wall of the worktable 1. The bottom end of the moving rod 15 is slidably fitted with the bottom inner wall of the sliding groove 10. An upwardly inclined slope is provided at both ends of the sliding groove 10. A rotating roller 20 is rotatably connected to the top outer wall of the bearing plate 12. A limit plate 17 is provided on the top outer wall of one end of the bearing plate 12.

[0028] The outer walls of the fixed frame 5 are provided with mounting brackets 18 that are fixedly connected to the top outer wall of the workbench 1. The top outer wall of the mounting bracket 18 is equipped with a telescopic rod 19, and the telescopic end of the telescopic rod 19 is connected to a pressure plate.

[0029] During production, the door frame is placed above the support plate 12. The positioning block 13 is located in the center hole of the door frame to limit the door frame. The moving component 4 drives the moving plate 2 to move, so that the door frame moves below the drill rod 9. The telescopic rod 1 6 pushes the first linear drive component 7 and the second linear drive component 8 to move down. At the same time, the telescopic rod 2 19 pushes the pressure plate to move down to press the door frame. The first linear drive component 7 and the second linear drive component 8 change the position of the drill rod 9, so that the drill rod 9 moves to the drilling position to drill. After drilling a door frame, the moving component 4 drives the moving plate 2 to move so that the door frame to be processed moves to the position where the drill rod 9 is lower. During the movement of the moving plate 2, the moving rod 15 moves along the sliding groove 10. The inclined surface at one end of the sliding groove 10 squeezes the moving rod 15, so that the moving rod 15 moves up and the spring 16 is compressed and deformed. The moving rod 15 pushes the support plate 12 to move up, so that the door frame moves up and gets away from the positioning block 13. At this time, the door frame can be pulled away to one side, and the rotating roller 20 reduces the friction between the door frame and the support plate 12.

[0030] By setting up a movable plate 2, a fixed component 3, a movable component 4, a mounting bracket 18, and a telescopic rod 19, the door frame can be pressed and fixed, while other door frames can be loaded and unloaded, reducing the overall operation time. At the same time, the movable plate 2 can automatically lift the door frame during its movement, making it easy to remove the door frame from the fixed component 3.

[0031] By providing a rotating roller 20, the friction between the door frame and the support plate 12 can be reduced, making it easier to move the door frame. Example 2

[0032] A drilling device for door frame production. This embodiment is based on embodiment 1 and makes the following improvements, such as... Figure 4 As shown, a rod 21 is fixedly connected to the top of the movable plate 2, and an insertion hole for inserting the rod 21 is opened on the outer wall of the positioning block 13. A clamping block 22 is threadedly connected to the top outer wall of the rod 21, and the clamping block 22 and the positioning block 13 are mutually limiting.

[0033] Since different door frames are of different sizes, a single-sized positioning block 13 cannot limit the position of different door frames. When drilling holes in different door frames, rotate the clamping block 22 to remove the clamping block 22, lift the positioning block 13 upwards and remove it, then place the new bearing plate 12 on the surface of the moving plate 2, insert the insertion rod 21 into the insertion hole, and then connect the clamping block 22 and the insertion rod 21 and tighten them to fix the positioning block 13 and replace the positioning block 13.

[0034] By setting the insertion rod 21 and the clamping block 22, it is easy to replace the fixing component 3 and limit the movement of door frames of different sizes.

[0035] Working principle: During production, the door frame is placed above the support plate 12. The positioning block 13 is located in the center hole of the door frame to limit its movement. The moving component 4 drives the moving plate 2 to move, so that the door frame moves below the drill rod 9. The telescopic rod 1 6 pushes the first linear drive component 7 and the second linear drive component 8 to move downwards. At the same time, the telescopic rod 2 19 pushes the pressure plate to move downwards to press the door frame. The first linear drive component 7 and the second linear drive component 8 change the position of the drill rod 9, so that the drill rod 9 moves to the drilling position to drill. After drilling one door frame, the moving component 4 drives the moving plate 2 to move, so that the door frame to be processed moves to the position where the drill rod 9 is lowered. During the movement of the moving plate 2, the moving rod 15 moves along the sliding groove 10. The inclined surface at one end of the 0 presses the moving rod 15, causing the moving rod 15 to move upward and the spring 16 to compress and deform. The moving rod 15 pushes the bearing plate 12 upward, causing the door frame to move upward and disengage from the positioning block 13. At this time, the door frame can be pulled away to one side, and the rotating roller 20 reduces the friction between the door frame and the bearing plate 12. Since different door frames are of different sizes, a single-sized positioning block 13 cannot limit the different sizes of door frames. When drilling holes for different door frames, rotate the clamping block 22 to remove the clamping block 22, lift the positioning block 13 upward and remove it. Then, place the new bearing plate 12 on the surface of the moving plate 2, insert the insertion rod 21 into the insertion hole, and then connect the clamping block 22 and the insertion rod 21 and tighten them to fix the positioning block 13 and replace the positioning block 13.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
