Product Description

The internal thread cylindrical positioning pin is an indispensable standardized component crucial for part positioning and connection within the realm of mechanical manufacturing and assembly. Featuring a distinctive structural design and exceptional functional attributes, this pin is pivotal in maintaining the accuracy and stability of mechanical components. Delve into a comprehensive introduction enfolding its structure, working principle, defining characteristics, application scenarios, user methods, and precautionary measures:

Structure: The core structure is cylindrical, with a refined smooth outer surface optimized to perfectly align with the pin holes of the parts being positioned. At one end, it boasts an internal threaded hole engineered for seamless integration with screws, bolts, or other connecting elements, allowing effortless operation during both installation and removal. This design also facilitates easy extraction using threaded tools such as pull-out implements. Conversely, the opposite end is typically enhanced with chamfers or round corners, ensuring streamlined insertion into pin holes.

Working principle: To achieve precise positioning, the internal threaded cylindrical positioning pin is inserted into the pre-machined pin hole of the positioned part. An interference or transition fit occurs between the cylindrical surface and the pin hole, adeptly restricting movement and rotation of the part within a plane. This precise positioning is fortified by coupling auxiliary parts or tools with internal threads, thereby preventing the pin from loosening or dislodging during operation, thus safeguarding the positioning stability.

• Characteristics

High positioning accuracy: The snug fit between the cylindrical surface and the pin hole offers an impeccable positioning reference for parts, significantly enhancing the assembly precision of mechanical components.

Easy disassembly: The innovative internal thread design simplifies tool disassembly, alleviating maintenance and replacement challenges, thereby optimizing work efficiency.

Reliable connection: Its ability to secure itself to other parts through threaded connections boosts positioning stability, making it ideal for environments prone to vibrations and impacts.

Diverse specifications: Available in a multitude of diameters, lengths, and thread specifications, these pins are engineered to satisfy the positioning demands across a variety of work conditions and parts.

• Application scenarios

Mold manufacturing: It plays a vital role in injection and stamping molds by positioning parts such as templates and inserts, ensuring the mold's fit precision and superior molding quality.

Mechanical processing: Integral in positioning workpieces within fixtures, it guarantees precise placement during processing, thus securing machining accuracy.

Equipment assembly: Essential during mechanical equipment assembly, it aligns components like boxes, gears, and shafts, securing their correct relative positions and ensuring the equipment's smooth operation.

• Instructions for use

1. Determine specifications: Choose internal threaded cylindrical locating pins that perfectly match the diameter, length, and thread specifications based on size, shape, precision demands, and the working load of the parts involved.

2. Machining pin holes: For parts requiring positioning, machine corresponding pin holes that comply with the positioning pin's dimensional accuracy, ensuring the pin holes' surface smoothness, dimensional precision, and positional accuracy.

3. Install the locating pin: Align the chamfered or corner end of the locating pin with the pin hole, then gently tap or press it, making sure it fits securely with the pin hole.

4. Fixation and connection: Depending on the needs, utilize screws, bolts, or similar connectors via the internal threaded holes to firmly secure the positioning pin to other parts.

• Precautions

Coordination accuracy: Meticulously manage the alignment precision between the positioning pin and the pin hole. Loose coordination can lead to positional inaccuracies, while overly tight coordination may pose installation challenges or even damage to parts.
