Description

Technical Field

[0001] This utility model belongs to the field of machining, especially the field of fixtures. Background Technology

[0002] A hand drill is a tool for drilling holes by hand. However, it's difficult to control the drilling direction with a hand drill. This has led to many related inventions, such as a center hole locator for wooden doves. This locator can only position the drill hole in wooden boards. Imagine trying to drill a hole in a pencil with a hand drill, aiming to only drill out the pencil lead. This operation is difficult because it's hard for a hand drill to be precisely positioned like that. If it's not drilling a pencil, but drilling a steel bar along its axis, the difficulty would be even greater. In other words, drilling a column along its axis is difficult. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model proposes an axial drilling positioning device, comprising a cylinder with a through hole along its axis, a nut fixedly connected to the bottom surface of the cylinder, and a screw rod matching the nut. The axis of the screw rod is parallel to the bottom surface of the cylinder, and the axis of the screw rod intersects the axis of the through hole.

[0004] The number of nuts is two or three. When there are two nuts, the axes of the two matching screws are on the same straight line. When there are three nuts, the three nuts equally divide the circumference of the bottom surface of the cylinder.

[0005] Furthermore, the cylinder is made of stainless steel.

[0006] Furthermore, the length of the cylinder along the axial direction is 2-5 cm.

[0007] This invention has a simple structure, is easy to manufacture, and is reliable and durable. Attached Figure Description

[0010] The following is in conjunction with the appendix Figure 1 This utility model will be further described below. Please see the appendix. Figure 1The axial drilling positioning device includes a cylinder 3 with a through hole 31 along its axis. The diameter of this through hole 31 is determined by the diameter of the drill bit used. For example, if the drill bit diameter is 3mm, the diameter of the through hole 31 can be 3mm or 3.3mm. A nut is fixedly connected to the bottom surface of the cylinder 3. The cylinder 3 has two planes: a top surface and a bottom surface. These are simply names; they refer to a single plane on the cylinder 3. The device also includes a screw that matches the nut. The axis of the screw is parallel to the bottom surface of the cylinder 3, and the axis of the screw intersects the axis of the through hole 31. This design allows the screw to firmly hold the workpiece in place, ensuring that the axis of the workpiece and the axis of the through hole 31 are aligned.

[0011] Why use a circular cylinder in this invention? Because the workpiece is usually circular, and using a circular cylinder makes it easier to determine whether the position of the workpiece is correct.

[0012] The number of nuts is two or three. When there are two nuts, the axes of the two matching screws are on the same straight line; when there are three nuts, the three nuts equally divide the circumference of the bottom surface of the cylinder 3. To ensure the screws firmly hold and position a rod-shaped workpiece, at least two screws are required, although three or four are also possible. However, due to precision requirements, usually not many are needed; generally, two or three are sufficient. The example given in the accompanying drawings of this utility model shows two screws: a first nut 1 with a matching first screw 11, and a second nut 2 with a matching second screw 21.

[0013] Furthermore, cylinder 3 is made of stainless steel. This design ensures that cylinder 3 is not easily damaged. We know that stainless steel is a very hard material; if cylinder 3 were made of wood, its aperture would enlarge after only a few uses. For a skilled worker, making cylinder 3 of iron would also be sufficient.

[0014] Furthermore, the length of cylinder 3 along its axial direction is 2-5 cm. We know that to ensure the position or direction of the drill bit, it must first pass through a hole, which restricts its direction and facilitates positioning. Therefore, the length of this through hole 31 cannot be too short. In typical use, the length of the through hole 31, or the length of cylinder 3 along its axial direction, is preferably 2-5 cm. If it is too short, the positioning effect will be poor; if it is too long, although the positioning effect can be guaranteed, the drill bit may not be long enough, and there is no need for an excessively long through hole 31.

[0015] The method of using this utility model is as follows: Place the cylindrical workpiece to be processed against the bottom surface of the through hole 31 at the drilled part, then rotate the screw until the workpiece is fixed in position and tightly held against the screw. Then, hold the hand drill and let the drill bit enter the through hole 31 from the top surface of the cylinder 3, and apply pressure by hand. Then, the drill bit will drill along the direction of extension of the through hole 31, thereby ensuring the direction of drilling.

[0016] This invention has a simple structure, is easy to manufacture, and is reliable and durable.
