Technical Field

[0001] This utility model relates to the field of workpiece drilling technology, specifically to a drilling positioning device. Background Technology

[0002] In wood processing, hand drills are frequently used to drill holes in wood. However, when workers use hand drills, the holes are easily drilled crookedly due to vibration or unstable drill holding, causing considerable trouble for subsequent processing and assembly steps. To address this, existing technologies have developed drilling positioning aids, such as the patent application CN202321288775.4. However, while existing drilling positioning aids can ensure drilling accuracy, they are not suitable for drilling angled holes with different inclination angles. Therefore, this application provides a drilling positioning device. Utility Model Content

[0037] Example

[0038] like Figure 1 As shown, this embodiment discloses a drilling positioning device, including: a base 1, two guide rods 2, two fixing components and a clamping component 4.

[0039] The base 1 has a hollow section 18 in the middle, meaning the base 1 is a rectangular frame. A mounting seat 11 is located on each of the opposite sides of the hollow section 18. The mounting seat 11 has slots, and the mounting ends of two guide rods 2 are respectively installed in the slots of the two mounting seats 11. The guide rods 2 can swing along the slots to adjust their angle. Two fixing components are connected to the two guide rods 2 respectively, and are used to fix the guide rods 2 to the mounting seats 11, i.e., the fixing components are used to fix the guide rods 2 at a certain angle. A clamping component 4 is connected between the two guide rods 2 and can move axially along the guide rods 2. It is used to clamp the drilling tools used for drilling.

[0040] like Figure 2As shown, the fixing assembly includes: a limiting gear 14, a screw 13, a locking nut 12, and a wing nut 15. The limiting gear 14 is located on the side of the mounting end of the guide rod 2, and its surface is provided with gear teeth 19, such as... Figure 6 As shown; the limiting gear 14 can be integrally formed with the guide rod 2. The screw 13 passes through the mounting base 11 and the limiting gear 14; the screw 13 and the mounting base 11 are interference fit, while the screw 13 and the limiting gear 14 are clearance fit, so the guide rod 2 can rotate with the screw 13 as the fulcrum. The locking nut 12 is locked at one end of the screw 13. The wing nut 15 is installed at the end of the screw 13 away from the locking nut 12; the front end of the wing nut 15 is provided with nut teeth that can mesh with the teeth 19 of the gear 19. When the wing nut 15 is turned forward, the nut teeth on the wing nut 15 can mesh with the teeth 19 of the gear 19, at which time the wing nut 15 can lock the guide rod 2. When in use, swing the guide rod 2 to the desired angle by hand and hold the guide rod 2 steady. Then, turn the wing nut 15 so that the nut teeth on the wing nut 15 engage with the teeth 19 of the gear plate. In this way, the guide rod 2 can be fixed at the desired angle.

[0041] In addition, such as Figure 5 As shown, the clamping assembly 4 includes a fixed clamping plate 41 with its two ends respectively mounted on two guide rods 2, and a movable clamping plate 42 connected to the fixed clamping plate 41 by fixing bolts 43. The fixed clamping plate 41 and the guide rods 2 are clearance-fitted, so the fixed clamping plate 41 can slide along the axial direction of the guide rods 2. The fixed clamping plate 41 and the movable clamping plate 42 are respectively provided with semi-circular clamping cavities 44 that can cooperate with each other. When the fixing bolts 43 are turned so that the movable clamping plate 42 is close to the fixed clamping plate 41, the semi-circular clamping cavities 44 on the fixed clamping plate 41 and the movable clamping plate 42 can form a complete clamping cavity, thereby clamping the drill bit.

[0042] In practice, a cap 5 can be provided at the top of the guide rod 2, which can prevent the clamping assembly 4 from detaching from the guide rod 2.

[0043] With the above structure, during use, the drilling positioning device is placed on the plate to be drilled, and the two guide rods 2 are adjusted to the required angle, such as... Figure 3 , 4 As shown, the drill bit is then clamped onto the clamping assembly 4, and the drill bit is pressed down. The clamping assembly 4 moves downward along the guide rod 2, and the drill bit drills a hole at a specific angle in the plate through the cutout 18. Since the clamping assembly 4 moves linearly along the guide rod 2, the drilling accuracy is not affected by the swinging of the drill bit during the drilling process. The guide rod 2 can be adjusted to different angles, thus allowing the drilling of inclined holes at different angles.

[0044] As another implementation method, such as Figure 1As shown, a support pad 10 is provided at the lower end of the guide rod 2, and a spring 9 is sleeved on the guide rod 2. The spring 9 is located between the support pad 10 and the clamping assembly 4. After drilling is completed, the operator can lift the drill bit without much force due to the restoring force of the spring 9.

[0045] In addition, an angle scale 17 can be set on the mounting base 11, and a pointer 3 pointing to the angle scale 17 is set on the support pad 10. When the angle of the guide rod 2 is adjusted, the pointer 3 will point to the corresponding scale simultaneously, so that the angle of the guide rod 2 can be adjusted more accurately.

[0046] A ruler rod 6 can also be installed on the support pad 10 of any guide rod 2. This ruler rod 6 is parallel to the guide rod 2 and passes through the clamping assembly 4; that is, the clamping assembly 4 can move along the ruler rod 6 and the guide rod 2. Furthermore, the ruler rod 6 has depth markings 16 along its axial direction, and a positioning sleeve 7 is slidably mounted on the ruler rod 6. The positioning sleeve 7 is equipped with a locking bolt 8 for locking the positioning sleeve 7 onto the ruler rod 6. Figure 1 As shown.

[0047] In use, press the drill bit down so that the lower end of the drill bit contacts the plate to be drilled. At this time, record the depth scale corresponding to the lower end of the clamping component 4. Adjust the positioning sleeve 7 to the corresponding depth scale position according to the required drilling depth. The required drilling depth is the value of the scale corresponding to the upper end of the positioning sleeve 7 minus the initially recorded scale value. After adjustment, press the drill bit down to start drilling. When the lower end of the clamping component 4 abuts against the positioning sleeve 7, the clamping component 4 can no longer move down. The depth of the hole drilled at this point is the required depth. In this embodiment, the setting of the ruler rod 6 and the positioning sleeve 7 can better control the drilling depth and improve the drilling effect.

[0048] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.
