Description

Technical Field

[0001] This utility model relates to the technical field of drilling guide devices, specifically a drilling guide device for sheet metal. Background Technology

[0002] In daily production and life, whether it is metal sheet or wood sheet, holes need to be drilled during processing to meet production and use standards. Drilling of sheet is a high-frequency basic operation. Its drilling accuracy directly affects the subsequent assembly quality, such as the firmness of hardware installation and the sealing of sheet splicing. The ease of operation determines the work efficiency and the ability to adapt to different scenarios.

[0003] Currently, drilling holes in sheet metal mainly uses a processing table. The sheet metal is fixed to the table surface, and a drilling mechanism is used to create holes. For example, a Chinese patent with publication number CN213055190U discloses a sheet metal drilling device. This device uses a lifting mechanism that slides along a longitudinal slide rail, causing a motor and drill bit assembly to approach the sheet metal to be drilled and further slide, allowing the drill bit to penetrate the sheet metal for drilling. This invention has advantages such as the ability to quickly adjust the drilling position and depth, improving drilling efficiency.

[0004] In the aforementioned literature, existing drilling devices are bulky and heavy, making them inconvenient to move and carry. They also cannot adjust the drilling angle, resulting in poor ease of use. Furthermore, the drilling angle is limited and cannot be adapted to different drilling angle requirements. In addition, traditional hand drills have poor precision and are prone to deviations or inaccurate drilling directions, leading to substandard drilling. Therefore, a board drilling guide device is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figure 1-5 As shown, a plate drilling guide device includes a square shell 1, inside which two sliding rods 2 are slidably arranged in opposite directions. The opposite ends of the two sliding rods 2 are fixedly connected to end rods 3, and suction cups 4 are detachably connected to the bottom of each end rod 3.

[0029] A vertical rod 5 is fixedly connected to the square shell 1. A bushing 6 is fixedly connected to the top of the vertical rod 5, and the center line of the bushing 6 is perpendicular to the vertical rod 5. A rotating rod 7 is rotatably installed inside the bushing 6. A guide plate 8 is fixedly connected to one end of the rotating rod 7, and the guide plate 8 is perpendicular to the center line of the rotating rod 7.

[0030] A limiting sleeve 14 is slidably provided on the side opposite to the rotating rod 7 of the guide plate 8. A drill rod 15 is rotatably installed inside the limiting sleeve 14. An internal hexagon connector 16 is fixedly connected to the top of the drill rod 15.

[0031] The bushing 6 is fixed with a scale 19 on the end face of the guide plate 8, and a pointer 20 is fixed on the rotating rod 7, with the working end of the pointer 20 slidably disposed on the scale surface of the scale 19.

[0032] Both sliding rods 2 have T-shaped limiting grooves 27 on their sides, and T-shaped limiting strips 28 are fixed on the inner wall of the square shell 1 and are respectively slidably fitted into the multiple T-shaped limiting grooves 27. The side walls between the two sliding rods 2 are also slidably connected to the T-shaped limiting strips 28 through the T-shaped limiting grooves 27.

[0033] Both sliding rods 2 have fastening grooves 24 on their upper surfaces. Two threaded sleeves 25 are fixed through the upper part of the square shell 1, and the two threaded sleeves 25 are directly opposite the openings of the fastening grooves 24 on the two sliding rods 2. Each threaded sleeve 25 is provided with a fastening bolt 26 that is threadedly connected to it, and the bottom ends of the two fastening bolts 26 extend and abut against the bottom of the two fastening grooves 24 respectively.

[0034] The end of the rotating rod 7 opposite to the guide plate 8 is fixedly connected to a worm gear 21. The worm gear 21 is provided with a worm 22 that meshes and drives with it. The worm 22 is rotatably mounted on the outer wall of the bushing 6. One end of the rotation center axis of the worm 22 is fixedly connected to a turntable 23.

[0035] The guide plate 8 has a guide groove 9 through it. Side plates 10 are fixedly connected to the side of the guide plate 8 opposite to the limiting sleeve 14 and to the upper and lower sides of the opening of the guide groove 9. Two limiting rods 11 are fixedly connected between the two side plates 10. A sliding block 12 is slidably provided on the two limiting rods 11. The limiting sleeve 14 passes through the guide groove 9 and is fixed to the sliding block 12.

[0036] Springs 13 are fitted on both of the limiting rods 11, and the springs 13 are located between the sliding block 12 and the lower side plate 10.

[0037] Both sliding rods 2 have baffles 29 fixed at their ends opposite to the fixed end rods 3 for limiting the position, and both pointers 20 have scales 30 on their upper surfaces.

[0038] The guide plate 8 has limiting holes 17 on both sides that communicate with the guide groove 9, and a rod 18 is inserted between the two opposing limiting holes 17.

[0039] During operation, existing drilling devices are bulky and heavy, making them inconvenient to move and carry. They also cannot adjust the drilling angle, resulting in poor ease of use. Furthermore, the drilling angle is limited and cannot be adapted to different drilling angle requirements. At the same time, traditional hand drills have poor precision and are prone to deviations or inaccurate drilling directions, resulting in substandard drilling. In this solution, in the initial state, the spring 13 will always push the sliding block 12 upward under the support of the lower side plate 10, so that the sliding block 12 slides upward on the limiting rod 11 and fits against the lower surface of the upper side plate 10. The limiting sleeve 14 drives the drill rod 15 to be lifted upward for grooving guidance processing.

[0040] In use, first pull the two sliding rods 2 in opposite directions to extend them, and place the device at the opening position of the plate. After the two sliding rods 2 have extended to a suitable length, tighten the two fastening bolts 26 through the threaded sleeves 25 and abut against the bottom of the fastening grooves 24 opened on the two sliding rods 2 to lock the two sliding rods 2. Then, use the two suction cups 4 to fix the device to the surface of the plate, so that the bottom end of the drill rod 15 is facing the drilling position so that drilling can be performed at the fixed position of the device.

[0041] Then, a hex wrench is installed on the output shaft of the hand drill, and the end of the hex wrench is fitted into the hexagonal groove of the internal hexagonal connector 16. The hand drill is then used to drive the drill rod 15 to rotate, and the drill rod 15 is pressed down as it rotates, causing the drill rod 15 to move downward. As the drill rod 15 moves downward, it slides on the two limit rods 11 through the sliding block 12. During the sliding process, the sliding block 12 presses down on the spring 13, so that the drill rod 15 can make a hole on the surface of the plate when it moves downward. Under the sliding restriction of the limit sleeve 14 by the two limit rods 11, the drilling direction of the drill rod 15 is guided, thus realizing the function of drilling guidance.

[0042] The rotating turntable 23 drives the worm gear 22 to rotate. Under the unidirectional driving action of the worm gear 22, the rotation angle of the rotating rod 7 is adjusted. The scale 19 slides on the scale surface of the pointer 20 to observe the opening tilt angle of the drill rod 15, thereby adjusting the opening angle and improving the opening accuracy. The installation height of the insertion rod 18 is adjusted so that it is placed in the two limiting holes 17 with openings at different heights. The insertion rod 18 is used to block the sliding block 12 from falling, thereby adjusting the opening depth of the drill rod 15 to meet different opening requirements.

[0043] It serves as a guide for drilling holes in boards and is more portable than traditional drilling devices, effectively improving ease of use. It also allows for adjustment of the drilling angle and depth, making it suitable for different drilling needs of boards and enhancing its applicability.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
