Description

Technical Field

[0001] This utility model relates to the field of tooling processing technology, specifically to a pin drilling mold. Background Technology

[0002] Small pins are a common type of component used in machining processes, widely applied in various precision equipment and mechanical structures. Small pins are approximately 120mm long and 19mm in diameter. Drilling is a crucial step in machining small pins. Currently, the 50mm and 80mm radial drilling machines are commonly used in drilling processes. While they perform well in machining general workpieces, the fixtures they require are typically quite large.

[0003] Due to the tiny size of these small pins, ordinary 50 and 80 radial drilling machine fixtures are highly incompatible with them, making it difficult to achieve a stable clamping. This not only leads to problems such as displacement and wobbling of the small pins during machining, seriously affecting the accuracy and quality of drilling, but also makes the clamping process cumbersome and time-consuming, greatly reducing production efficiency.

[0004] In today's industrial environment that pursues efficient, high-quality, and mass production, the predicament caused by the mismatch between fixture and workpiece dimensions makes it difficult for existing machining methods to meet the production needs of mass drilling of small pins. Therefore, existing technologies need further development. Utility Model Content

Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0025] Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model.

[0026] According to an embodiment of this utility model, a pin drilling mold is provided. Please refer to [link / reference]. Figures 1 to 3 The mold includes a cylindrical structure 2 with a space for accommodating pins. One end of the cylindrical structure 2 has a feed inlet 21, and the other end has an adjusting component for adjusting the internal space. The cylindrical structure 2 has a drilled hole 5, a fixing hole 6, and a fixing structure 3 for fixing the pins on its circumferential sidewall. The fixing structure 3 is disposed on the fixing hole 6 and can move along the fixing hole 6. The mold prepared in this application can effectively clamp small-sized pins, meeting the production needs of mass drilling of small-sized pins. It has a simple structure and a reasonable design.

[0027] Specifically, the interior of the cylindrical structure 2 is hollow and has a space for accommodating the pin. It is machined according to the diameter of the pin. The pin enters from the feed port 21. The adjusting component enters the space from the other end of the cylindrical structure 2 and contacts the pin. By adjusting the amount of the adjusting component entering the space, the drilling position of the internal pin is adjusted.

[0028] like Figure 1 As shown, the cylindrical structure 2 has a drill hole 5 on its circumferential sidewall to accommodate a drill bit, allowing the drill bit to drill a hole in the pin. The fixing structure 3 applies force to the pin by moving along the fixing hole 6 to fix the pin.

[0029] The fixing structure 3 is a fixing bolt, which includes a bolt head and a bolt shank. The bolt shank is inserted into the fixing hole 6. Rotating the bolt head causes the bolt shank to rotate and move along the fixing hole 6 towards the pin, applying force to the pin and thus fixing it in place.

[0030] The fixing hole 6 has an internal thread corresponding to the bolt shank. Machining an internal thread inside the fixing hole 6, with the thread corresponding to the bolt shank, makes it easier for the bolt shank to rotate and move along the fixing hole 6.

[0031] like Figure 3 As shown, the distance L2 between the fixing hole 6 and one end of the cylindrical structure 2 with the feed inlet 21 is less than the distance L1 between the fixing hole 6 and one end of the cylindrical structure 2 with the adjustment component.

[0032] The adjusting component includes a nut 11 and an adjusting bolt 12. The nut 11 is fixed to the other end of the cylindrical structure 2, and the adjusting bolt 12 enters the receiving space of the cylindrical structure 2 through the nut 11. Specifically, the nut 11 can be welded to the other end of the cylindrical structure 2, and the adjusting bolt 12 can rotate in and out to adjust the size of the space inside the cylindrical structure 2, thereby adjusting the drilling position of the pin.

[0033] The pin drilling mold also includes a base 4, on which the cylindrical structure 2 is located, and the circumferential sidewall of the cylindrical structure 2 contacts the base 4. The base 4 can be clamped on the clamping platform of a vertical bench drill.

[0034] The cylindrical structure 2 is fixedly connected to the base 4. The base 4 can be a rectangular steel structure.

[0035] like Figure 2 As shown, the base 4 has an arc-shaped groove 41, and the cylindrical structure 2 is placed inside the arc-shaped groove 41. The circumferential sidewall of the cylindrical structure 2 is in contact with the arc-shaped groove 41.

[0036] like Figure 3 As shown, the distance L4 between the drill hole 5 and one end of the cylindrical structure 2 with the feed inlet 21 is greater than the distance L3 between the drill hole 5 and one end of the cylindrical structure 2 with the adjustment component.

[0037] The cylindrical structure 2 can be a hollow round steel bar. A sleeve is machined from the round steel bar according to the diameter of the pin to accommodate the pin to be processed.

[0038] The fixing bolt is located near the feed inlet 21. Rotating the fixing bolt downwards applies force to the pin to fix it in place.

[0039] The other end of the cylindrical structure is welded with a nut 11. The adjusting bolt 12 can be rotated in and out to adjust the size of the internal space of the cylindrical structure 2, thereby adjusting the drilling position of the internal pin.

[0040] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
