Description

Technical Field

[0001] This utility model relates to the field of transformers, and more specifically to a PIN pin limiting module for a high-speed pin insertion machine. Background Technology

[0002] In modern industrial production, wire processing equipment is widely used in electronics, electrical engineering, and communications. This type of equipment typically requires different models of pin guide devices to be used depending on the product specifications. However, existing pin guide devices have the following significant drawbacks:

[0003] Existing PIN pin limiting modules typically use a single screw fixation method, which exhibits several shortcomings in practical applications. Firstly, single-point fixation results in rotational freedom of the module, making it difficult for operators to accurately locate and calibrate the device's center point, requiring complex position adjustments after each replacement. According to production practice data, this debugging process usually takes no less than 2 hours, severely impacting production efficiency and equipment utilization.

[0004] Secondly, the existing design lacks versatility. Different PIN specifications require replacing the entire limiting module, not just the guide pin, which not only increases spare parts costs but also extends replacement time. Since each PIN requires a dedicated limiting module, companies need to stock multiple sets of modules, increasing inventory management burden.

[0005] In addition, the existing guide pin fixing mechanism poses a potential risk of damage to the wire. During the production process, if the guide pin is not securely fixed or its position is misaligned, it can easily cause scratches, deformation, or breakage of the wire, directly affecting product quality and production pass rate.

[0006] Furthermore, the guide pins in existing technologies are at risk of loosening or falling off during equipment operation. Once the guide pin falls off, it will not only interrupt production, but may also damage other precision components of the equipment, causing wider equipment failures and longer downtime for maintenance.

[0007] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0008] The purpose of this invention is to provide a PIN pin limiting module for a high-speed pin insertion machine, so as to overcome the above-mentioned shortcomings and deficiencies of the prior art.

[0009] A PIN pin limiting module for a high-speed pin insertion machine includes: a base, fixed sides, an upper guide pin hole, a fixed guide pin hole, and a tapered opening. The base has fixed sides symmetrically arranged on both sides, and the fixed sides have an L-shaped structure. The upper guide pin hole is located at the top of the base, the tapered opening is located at the bottom of the base, and the fixed guide pin hole is located on the front of the base. There are two fixed guide pin holes, and the upper and lower ends of the fixed guide pin holes are respectively provided with an upper guide pin hole and a tapered opening.

[0010] Furthermore, the fixed side is provided with a waist hole structure, which is connected to the cutter guide rail by double screws.

[0011] Furthermore, the tapered opening matches the tapered outer diameter of the guide pin, and the guide pin fixing hole is fixedly connected to the guide pin by screws during use.

[0012] The beneficial effects of this utility model are:

[0013] Compared with traditional technologies, this invention replaces the original design with a module for loading guide pins. The guide pins are secured by screws on both sides and double set screws, significantly improving stability. The tapered opening at the bottom prevents the guide pins from escaping due to external force, avoiding damage to other operating components. The PIN replacement process is optimized, reducing the time required from over two hours to simply replacing the guide pin without needing to adjust its position. This greatly shortens replacement time, accelerates production, and improves equipment utilization and production efficiency. Attached image description:

[0017] The base 100, fixed side 200, waist hole structure 210 with guide pin hole 300, fixed guide pin hole 400, tapered opening 500 and guide pin 1. Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0019] Example 1

[0020] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a diagram showing the usage state of this utility model.

[0021] like Figure 1-2As shown, a PIN pin limiting module for a high-speed pin insertion machine includes: a base 100, a fixed side 200, an upper guide pin hole 300, a fixed guide pin hole 400, and a tapered opening 500. The fixed side 200 is symmetrically arranged on both sides of the base 100. The fixed side 200 has an L-shaped structure. The upper guide pin hole 300 is located at the top of the base 100, and the tapered opening 500 is located at the bottom of the base 100. The fixed guide pin hole 400 is located on the front of the base 100. There are two fixed guide pin holes 400. The upper guide pin hole 300 and the tapered opening 500 are respectively provided at the upper and lower ends of the fixed guide pin hole 400.

[0022] The fixed side 200 is provided with a waist hole structure 210, which is connected to the cutter guide rail by double screws.

[0023] The tapered opening 500 matches the tapered outer diameter of the guide pin 1, and the guide pin hole 400 is fixedly connected to the guide pin 1 by screws during use.

[0024] Compared with traditional structures, this utility model has the following innovations: Firstly, it features symmetrical fixed sides 200, allowing for double-screw fixation of the entire structure via the waist hole structure 210 of the fixed sides 200, resulting in high stability. Traditional designs use a single-side design, but single-screw fixation allows for rotational freedom, enabling the module to rotate around this point and leading to inaccurate positioning. The dual-screw fixation design of this utility model provides two definite reference points, forming a fixed reference line. The geometric principle that two points determine a straight line ensures the module's position is uniquely determined, eliminating the possibility of rotation and offset, and eliminating the need to find a center point. Installation only requires aligning with the two preset screw holes, without complex calibration. Secondly, the guide pin 1 is fixed using two fixed guide pin holes 400 in conjunction with screws, ensuring high stability. Thirdly, a tapered opening 500 is provided below the fixed guide pin holes 400 to prevent the guide pin from escaping the module due to external force, thus preventing damage to other operating components. The tapered opening 500 matches the tapered outer diameter of the guide pin, forming a wedge fit. When the guide pin is subjected to external force, such as vibration or impact, the friction between the conical surfaces increases. This wedge-shaped structure makes the guide pin more secure under force, similar to the principle of self-locking threads or conical plugs, preventing the guide pin from loosening or falling off during operation.

[0025] Finally, traditionally, different PIN pins require replacing the entire limiting module and recalibrating their positions. In contrast, the module itself is securely positioned by screws on both sides, ensuring a fixed position. The guide pin 1 can be individually removed and installed from the module using double set screws and a tapered opening design. The module is designed to accommodate different types of guide pins; only the guide pin itself needs to be replaced. Since the module position remains unchanged, time-consuming recalibration is unnecessary.

[0026] In summary, through the above structural optimization, the PIN replacement time has been reduced from at least 2 hours to simply replacing the guide pin without adjusting its position. This significantly shortens the PIN replacement time and greatly accelerates the production pace.

[0027] Compared with traditional technologies, this invention replaces the original design with a module for loading guide pins. The guide pins are secured by screws on both sides and double set screws, significantly improving stability. The tapered opening at the bottom prevents the guide pins from escaping due to external force, avoiding damage to other operating components. The PIN replacement process is optimized, reducing the time required from over two hours to simply replacing the guide pin without needing to adjust its position. This greatly shortens replacement time, accelerates production, and improves equipment utilization and production efficiency.

[0028] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
