Technical Field

[0001] The utility model belongs to the field of rod positioning fixtures, in particular to a rod hole positioning device. Background Art

[0002] There are many types of rods used in the figurine production process. In terms of material, there are plastic and metal rods. Plastic rods are lightweight and easy to process and shape, making them suitable for smaller figures or parts that require weight. Metal rods are sturdier and can support heavier parts. For large, complex figures, such as those with large wings, metal rods provide better support for the wings.

[0003] Drilling holes in the rod is a relatively delicate operation; the purpose of drilling holes is mainly to install other components or connect different parts of the figure; for example, when connecting the limbs and body of the figure, it may be necessary to drill holes in the rod and insert pins to fix the limbs so that they can move; when drilling holes, the size of the hole should be determined according to the size of the connected parts; if the hole is too large, the connection will be unstable; if the hole is too small, the parts cannot be inserted.

[0004] A small hand drill is usually used to make holes, and the position needs to be accurately marked before drilling. At this time, tools such as calipers can be used to measure and locate the holes to ensure that the position of the holes is accurate, thereby ensuring the overall coordination and stability of the various parts of the figure after they are connected.

[0005] In order to reduce measurement errors, we designed a positioning device for rod hole opening to assist in rapid hole positioning. Utility Model Content

The positioning module 1 is divided into an upper module 101 and a lower module 102 along the axis of the positioning socket 3. Half of the positioning socket 3 is located on the upper module 101, and the other half is located on the lower module 102. The positioning hole plate 2 is installed on the lower module 102. The upper module 101 and the lower module 102 are connected by a clamping bolt 7. A through hole 5 is provided on the upper module 101, and a threaded through hole 6 is provided on the lower module 102 corresponding to the through hole 5. A clamping bolt 7 is movably provided in the through hole 5. The clamping bolt 7 is threadedly connected with the threaded through hole 6. The bottom side of the head of the clamping bolt 7 is in contact with the top side of the upper module 101. The utility model has a simple structure and an ingenious design. Through the cooperation of the upper module 101 and the lower module 102, the rod is inserted into the positioning socket 3, the rod is quickly clamped, and a coaxial hole is conveniently opened at the end of the rod. At the same time, the rod can also be inserted into the socket 8, which is convenient for opening a hole on the side of the rod. It is easy to use and operate, can meet design requirements, and is suitable for promotion. When using the present invention, when opening a hole at the end of the rod, first adjust the spacing between the upper module 101 and the lower module 102 by tightening the clamping bolt 7 to open the positioning socket 3, and then insert the rod into the positioning socket 3 of appropriate diameter, and make the end of the rod contact and cooperate with the positioning hole plate 2, and then tighten the clamping bolt 7. The rod is clamped in the positioning socket 3 between the upper module 101 and the lower module 102, completing the clamping and positioning of the rod. At this time, the rod is coaxially arranged with the positioning socket 3 and the positioning hole 4. At this time, insert the drill bit of the hand drill into the positioning hole 4, and a coaxial hole can be quickly opened at the end of the rod; when it is necessary to open a hole on the side of the rod, insert the rod into the socket 8 of appropriate diameter, and control the distance of the rod inserted into the socket 8 so that the hole position is aligned with the positioning hole 4, and then a hole can be opened on the side of the rod.

[0022] Specifically, as shown in the figure, the cross-section of the positioning socket 3 in this embodiment is square.
