Abstract
Description
Technical Field
[0001] This utility model relates to a hole-opening device, and more particularly to a keyhole hole-opening device. Background Technology
[0002] During the manufacturing process of door panels, mounting holes for lock installation are made on the door panels to facilitate the subsequent installation of locks. At the same time, in order to ensure the efficiency of drilling, drilling devices are usually used to drill holes in the door panels.
[0003] In existing technologies, such as the stainless steel door panel side lock hole milling device disclosed in CN219746443U, a transparent soft curtain for preventing splashing is set around the milling cutter. This effectively prevents the splashing of various metal chips when milling lock holes on the side of doors and windows, thus playing a good protective role in protecting the personal safety of operators.
[0004] However, it also has some shortcomings. For example, it can only make holes on the side of the door panel when it is working. The only holes on the side wall of the door panel are the lock body hole (for accommodating the lock body) and the bolt hole (for the bolt or latch to extend and retract from the lock body). If it is necessary to make a lock cylinder hole that penetrates the door panel (for inserting the key into the lock cylinder of the lock body), other hole-making devices are required, which will reduce the processing efficiency of the door panel. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a lock hole opening device that can simultaneously open a lock body hole, a lock tongue hole and a lock cylinder hole on a door panel.

The second moving mechanism is installed on the side wall of the worktable and is used to control the second support frame to move left and right along the side wall of the worktable. The third moving mechanism is installed on the first support frame and is used to control the first opening mechanism to move left and right above the door panel to be processed. The first moving mechanism, the second moving mechanism, and the third moving mechanism are all screw moving mechanisms.

[0009] A further preferred embodiment of this utility model is as follows: two locking blocks are provided on the worktable to restrict the movement of the door panel to be processed, and a through groove is provided on the worktable between the locking blocks. The locking blocks and the through groove are on the side of the worktable near the second opening mechanism. A protective pad for supporting the door panel to be processed is also provided on the worktable between the locking blocks.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0027] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.
[0028] This embodiment mainly describes the structure of the keyhole opening device, as follows:
[0029] like Figures 1-8As shown, the lock hole opening device includes a worktable 1 for placing the door panel 11 to be processed flat and a first support frame 2 installed on the worktable 1. When the door panel 11 to be processed is on the worktable 1, it is located inside the first support frame 2. Then, a first opening mechanism 3 for opening the lock cylinder hole is provided on the first support frame 2, and a second support frame 9 is provided on the side wall at the rear end of the worktable 1. A second opening mechanism 4 for opening the lock body hole and the lock tongue hole is provided on the second support frame 9. In this way, when the lock hole opening device is working, the door panel 11 to be processed is first placed on the worktable 1, and then the first opening mechanism 3 is activated to open the lock cylinder hole in the door panel 11. After the lock cylinder hole is opened, the second opening mechanism 4 is activated to open the lock body hole and the lock tongue hole on the side wall of the door panel 11. Thus, when the lock hole opening device is opening a lock hole on the door panel, it can simultaneously open the lock cylinder hole, the lock body hole and the lock tongue hole on the panel, thereby improving the processing speed of the door panel and thus improving the processing efficiency of the door panel.
[0030] To facilitate the first opening mechanism 3 and the second opening mechanism 4 in creating lock holes at different positions on the door panel 11 to be processed, three moving mechanisms 5 are provided on the workbench 1 and the first support frame 2. The three moving mechanisms 5 are as follows: a first moving mechanism 51 is provided on the workbench 1 to control the reciprocating movement of the first support frame 2 on the workbench 1. When the first moving mechanism 51 controls the movement of the first support frame 2, the first opening mechanism 3 installed on the first support frame 2 can also reciprocate back and forth above the workbench 1. Then, a second moving mechanism 52 is provided on the side wall at the rear end of the workbench 1 to control the reciprocating movement of the second support frame 9 along the side wall of the workbench 1. Thus, when the second moving mechanism 52 controls the movement of the second support frame 9, the first opening mechanism 3 installed on the first support frame 2 can also reciprocate back and forth above the workbench 1. When the support frame 9 moves, the second hole-opening mechanism 4 installed on the second support frame 9 can move back and forth along the side wall of the workbench 1 as the second support frame 9 moves. Finally, a third moving mechanism 53 is provided on the first support frame 2 to control the first hole-opening mechanism 3 to move back and forth above the door panel 11 to be processed. In this way, the first hole-opening mechanism 3 and the second hole-opening mechanism 4 can open lock holes at different positions on the door panel 11 to be processed through the cooperation of the first moving mechanism 51, the second moving mechanism 52 and the third moving mechanism 53, thereby improving the practicality of the lock hole opening device. The first moving mechanism 51, the second moving mechanism 52 and the third moving mechanism 53 are all screw moving mechanisms 5.
[0031] Furthermore, the first drilling mechanism 3 includes a first mounting plate 31 mounted on the first support frame 2, with the top of the first mounting plate 31 connected to the third moving mechanism 53. A first telescopic device 32 is provided at the bottom of the first mounting plate 31, and a first connecting plate 33 is provided at the telescopic end of the first telescopic device 32. A first drive motor 34 is provided at the bottom of the first connecting plate 33, and a first drilling cutter 37 for drilling lock cylinder holes is provided at the output end of the first drive motor 34. Thus, when the first drilling mechanism 3 is in use, it... The first telescopic device 32 is activated and its telescopic end is extended. As the telescopic end of the first telescopic device 32 is extended, the first drive motor 34, together with the first hole-opening cutter 37, can be controlled to move toward the door panel 11 to be processed on the worktable 1 until the first hole-opening cutter 37 completes the opening of the lock cylinder hole through the door panel 11. After the lock cylinder hole is opened, the first telescopic device 32 is activated again and its telescopic end is shortened. At this time, the first drive motor 34 and the first hole-opening cutter 37 move away from the door panel 11 to be processed.
[0032] To ensure the secure connection between the first drive motor 34 and the first connecting plate 33, a plurality of L-shaped fixing plates 35 are arranged circumferentially on the outer wall of the first drive motor 34, and the top of the fixing plate 35 is connected to the bottom of the first connecting plate 33. At the same time, to ensure the stability of the first hole-opening knife 37 during operation, a first spring telescopic rod 36 is provided at the bottom of each fixing plate 35, and a first pressure plate 38 is provided at the telescopic end of the first spring telescopic rod 36 to abut against the door panel 11 to be processed. At the same time, to facilitate the first hole-opening knife 37 to pass through the first pressure plate 38, a first through hole for the first hole-opening knife 37 is provided on the first pressure plate 38.
[0033] Furthermore, in order to improve the stability of the first telescopic device 32 during operation, multiple telescopic rods 39 are provided around the bottom of the first mounting plate 31, and the telescopic ends of the telescopic rods 39 are connected to the first connecting plate 33.
[0034] Furthermore, in order to prevent the first pressure plate 38 from pressing indentations on the door panel 11 to be processed during operation, a first pressing ring 381 made of rubber is provided at the bottom of the first pressure plate 38.
[0035] The second opening mechanism 4 includes a second mounting plate 41 mounted on the second support frame 9, with a second telescopic device 42 horizontally mounted on the second mounting plate 41. A second connecting plate 43 is slidably mounted on the second support frame 9 and connected to the telescopic end of the second telescopic device 42. Thus, the second connecting plate 43 can be controlled to move closer to or further away from the worktable 1 on the second support frame 9 by using the second telescopic device 42. A second drive motor 44 is mounted on the side wall of the second connecting plate 43 near the worktable 1, and the output end of the second drive motor 44 is provided with a hole for opening the lock body hole and the lock tongue hole. The second drilling cutter 49 is provided. In order to ensure the stability of the second drilling cutter 49 during operation, a third mounting plate 45 is provided on the side wall of the output end of the second drive motor 44, and the output end of the second drive motor 44 passes through the third mounting plate 45. Then, a second spring telescopic rod 48 is provided on the third mounting plate 45 on the left and right sides of the output end of the second drive motor 44. At the same time, a limiting block 46 is provided at the telescopic end of the second spring telescopic rod 48 to engage with the door panel 11 to be processed. In order to facilitate the second drilling cutter 49 to pass through the limiting block 46, a second through hole for the second drilling cutter 49 is provided on the limiting block 46.
[0036] Furthermore, a fixing block 47 for supporting the second drive motor 44 is provided on the second connecting plate 43, and in order to improve the fitting effect between the fixing block 47 and the outer wall of the second drive motor 44, a groove is provided on the fixing block 47 to fit with the outer wall of the second drive motor 44.
[0037] Furthermore, to facilitate the restriction of the movement of the door panel 11 to be processed on the workbench 1, two locking blocks 7 are also provided on the workbench 1 to restrict the movement of the door panel 11 to be processed. At the same time, in order to prevent the first hole-opening mechanism 3 from damaging the workbench 1 when opening the lock cylinder hole, a through groove 10 is provided on the workbench 1 between the locking blocks 7, and the locking blocks 7 and the through groove 10 are on the side of the workbench 1 closer to the second hole-opening mechanism 4. At the same time, a protective pad 8 is also provided on the workbench 1 between the locking blocks 7 to support the door panel 11 to be processed, and the height of the protective pad 8 protrudes from the upper surface of the workbench 1. Thus, when the door panel 11 to be processed is placed on the protective pad 8, the door panel 11 to be processed is suspended on the side closer to the second hole-opening mechanism 4, which facilitates the locking of the side of the door panel 11 to be processed by the limiting block 46.
[0038] Furthermore, to improve the stability of the door panel 11 to be processed on the workbench 1, two clamping components 6 are respectively provided on the side walls at the front and rear ends of the first support frame 2. Each clamping component 6 includes a fourth mounting plate 61 connected to the side wall of the first support frame 2, and a third telescopic device 62 is provided at the bottom of the fourth mounting plate 61. The telescopic end of the third telescopic device 62 faces the upper surface of the workbench 1. A second pressure plate 63 is provided at the telescopic end of the third telescopic device 62 to clamp the door panel 11 to be processed. In this way, when the third telescopic device 62 extends, the second pressure plate 63 can be controlled to move toward the upper surface of the door panel 11 to be processed until the second pressure plate 63 clamps the door panel 11 to be processed, thereby improving the stability of the door panel 11 to be processed on the workbench 1.
[0039] Furthermore, in order to prevent the second pressure plate 63 from pressing indentations on the door panel 11 to be processed during operation, a second pressing ring 64 made of rubber is provided at the bottom of the second pressure plate 63.
