[0022] Example: As attached Figure 1-3 As shown, this utility model describes a vertical drilling and tapping device, including a base 1, the bottom surface of which is preferably flat. A window 11 vertically penetrates the base 1. A drill chuck 2 is positioned directly above the window 11, used to hold a drill bit. The drill chuck 2 is mounted on a movable spindle box 4 via a drill chuck taper shank 3. The drill chuck taper shank 3 is rotatably connected to the movable spindle box 4, and the top end of the drill chuck taper shank 3 extends upwards out of the movable spindle box 4. The drill chuck taper shank 3 and the movable spindle box 4 are rotatably connected by a bearing, preferably a stepped bearing. The outer diameter of the drill chuck taper shank 3 is smaller than the maximum outer diameter of the drill chuck 2, and a boss limiting member is provided on the drill chuck taper shank 3, located at the top of the stepped bearing. The drill chuck taper shank 3 is used to connect to an electric drill.

[0023] The base 1 is provided with a guide frame 5 to guide the up and down movement of the movable spindle box 4. The guide frame 5 is provided with a height-adjustable limiting block 6. The limiting block 6 is located on the lower side of the movable spindle box 4 and is used to limit the downward movement of the movable spindle box 4. The top of the limiting block 6 is provided with a scale 61. The movable spindle box 4 is provided with a marking line 41 corresponding to the zero mark line of the scale 61.

[0024] Preferably, one end of the base 1 is provided with a grip handle 12. When gripping the grip handle 12, the present invention can be easily and effectively stabilized on the surface of the object to be drilled, which is both labor-saving and stable.

[0025] Preferably, the base 1 is provided with a dust collection hood 13, which can collect the dust generated during drilling.

[0026] Preferably, the dust collection hood 13 is detachably connected to the base 1, and the dust collection hood 13 can be installed as needed.

[0027] The dust cover 13 and the base 1 can be connected by magnetic force. The dust cover 13 is a magnetic dust cover 13. The window 11 is a U-shaped notch set at one end of the base 1. The dust cover 13 is installed at the open end of the U-shaped notch.

[0028] Preferably, the base 1 and / or guide frame 5 are equipped with LED lights 14, which can facilitate observation of the drilling position.

[0029] Preferably, the base 1 is provided with a plurality of expansion holes 15.

[0030] Specifically: The base 1 has four expansion holes 15 for installing expansion parts, making its use more extensive; the base 1 has a built-in LED light 14, a battery compartment inside, and a self-locking switch at the rear. The LED light 14 can be turned on before drilling to illuminate the drilling area, facilitating processing; the base 1 adopts a square structure, and the X and Y axes can be used for positioning and support, etc. A V-shaped notch is provided at the drilling position for positioning after drawing lines.

[0031] Preferably, to ensure the stability of the movable spindle box moving up and down, the guide frame 5 includes a top cover 51 and several vertically arranged guide rods 52. The guide rods 52 are optical axes. The bottom end of the guide rods 52 is fixed on the base 1, and the top end is connected to the top cover 51. The movable spindle box 4 is vertically provided with guide holes that are adapted to the guide rods 52. The limiting block 6 is located on one of the guide rods 52.

[0032] Furthermore, there are three guide rods 52, which form a triangular prism shape.

[0033] Furthermore, the limiting block 6 is located on one of the guide rods 52, and springs 53 are sleeved on the other guide rods 52. One end of the spring 53 abuts against the movable spindle box 4, and the other end abuts against the base 1. The spring 53 gives the movable spindle box 4 an upward thrust, which enables the present invention to quickly reset.

[0034] Preferably, to ensure the stability of the locking of the limiting block on the guide rod, the limiting block 6 is provided with a vertical through hole adapted to the guide rod 52, and a hand-tightening screw 62 is provided on the outer wall of the limiting block 6. The outer wall of the guide rod 52 on which the limiting block 6 is installed is provided with a vertical groove 54 adapted to the hand-tightening screw 62. The bottom surface of the groove 54 is a flat surface, which can increase the working area of ​​the hand-tightening screw 62 relative to the arc surface of the guide rod 52, increase the friction between the hand-tightening screw 62 and the guide rod 52, and ensure the stability of the locking. The hand-tightening screw 62 is a screw that is easy to tighten by hand, such as a wing screw or a screw with a knob on the head.

[0035] The top of the limiting block 6 is equipped with a scale 61. The limiting block 6 has a standard size scale, so there is no need to calculate the drilling depth. Traditional fixed scales require calculation for each drilling depth adjustment. This device is in the zero position before use. After the drilling depth is determined, there is no need to calculate. Simply slide the limiting block 6 to the scale where the drilling depth is required and lock it. This can effectively ensure the drilling depth when drilling.

[0036] This invention features high drilling perpendicularity, making it easy to drill holes with good perpendicularity on the surface of objects. Furthermore, it is widely applicable, as drilling holes with certain perpendicularity requirements is often necessary during production operations. Sometimes, the size of the object may be too large to be easily transported to a bench drill for processing. This tool allows for convenient processing regardless of the location.

[0037] One method of using this utility model is as follows:

[0038] 1) Press the self-locking switch to turn on LED light 14;

[0039] 2) Use the key of the electric drill to install and lock the drill bit or tap onto the drill chuck 2 of this utility model;

[0040] 3) Install and lock the drill chuck of the electric drill to the upper end of the drill chuck cone shank 3 of this utility model;

[0041] 4) Place this utility model on the surface of an object that needs to be drilled or tapped;

[0042] 5) Press down on the electric drill, align the center of the drill bit with the center of the hole to be drilled or tapped;

[0043] 6) Confirm the required drilling or tapping depth, then move the limit block 6 on the guide rod 52 to the corresponding scale position according to the required drilling or tapping depth, and then tighten the hand screw 62 to lock the limit block 6.

[0044] 7) Hold the handle 12 with your left hand, start the electric drill, and drive the drill chuck 2 on the movable spindle box 4 to perform drilling or tapping. When the movable spindle box 4 presses down and touches the limit block 6, it can no longer press down. The electric drill is lifted up by the pushing force of the spring 53 on the guide rod 52, and the processing is completed.
