Description

Technical Field

[0001] This utility model relates to the field of elastic pin processing technology, specifically to an elastic pin processing hole-punching anti-deviation structure. Background Technology

[0002] Elastic cylindrical pins, also known as spring pins, are headless, hollow cylindrical bodies with axial slots and chamfered ends. They are used for positioning, connecting, and fixing parts. They require good elasticity and shear resistance. The outer diameter of these pins is slightly larger than the assembly hole diameter. Elastic cylindrical pins are generally formed by coiling. Drilling is a crucial step in machining elastic pins. Due to the material and structural characteristics of elastic pins, traditional drilling methods easily lead to hole misalignment, affecting machining accuracy and product quality. Therefore, a machining structure that can effectively prevent hole misalignment is urgently needed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0021] Please see Figure 1 As shown, this utility model provides a structure for preventing deviation during drilling of elastic pins, including a support plate 1. A processing platform 2 is fixedly installed on the top of the support plate 1. A positioning hole 3 is opened in the middle of the processing platform 2. A spring 4 is installed inside the positioning hole 3 and embedded inside the processing platform 2. A pull rod 5 is sleeved inside the spring 4. An arc-shaped clamping plate 6 is installed at the rear end of the pull rod 5. The front end of the pull rod 5 extends to the front of the processing platform 2. A guide sleeve 9 is installed above the positioning hole 3. A positioning seat 10 is fixedly installed at the front end of the top of the processing platform 2. An adjusting screw 11 is rotatably installed inside the positioning seat 10, and the rear end of the adjusting screw 11 is rotatably installed on the surface of the guide sleeve 9.

[0022] This technical solution ensures that the elastic pin is fixed in position during processing by adding an arc-shaped clamping plate 6 and an elastic pad 7 inside the positioning hole 3, avoiding processing errors caused by offset. In addition, the design of the guide sleeve 9 ensures the accurate movement trajectory of the drilling tool, further improving the accuracy of the drilling position. The overall structure design effectively reduces errors caused by human operation or equipment vibration, ensuring the consistency of processing results. Example

[0023] Based on Embodiment 1, this utility model is as follows: Figure 3 As shown, the top of the processing platform 2 is provided with guide grooves 12 on both sides in the longitudinal direction. A guide slider 13 is slidably connected inside the guide groove 12. The top of the guide slider 13 is connected to the surface of the guide sleeve 9 through a connecting rod 14. An adjustable elastic pad 7 is vertically installed on the rear side of the cavity of the positioning hole 3. A rubber pad 8 is installed above the positioning hole 3 and at the bottom of the guide sleeve 9. The top of the rubber pad 8 is in sliding contact with the bottom of the guide sleeve 9.

[0024] Adopting such Figure 1The technical solution shown features a spring clip inside the positioning hole 3, which provides a stable clamping force to prevent the elastic pin from loosening or moving during processing. The elastic pad 7 absorbs vibrations and impacts during processing, ensuring the stability of the processing. The rubber pad 8 added above effectively resists the influence of external forces or vibrations on the position of the elastic pin from the guide sleeve 9, ensuring the reliability of the processing.

[0025] Secondly, in the technical solution, a through groove is provided on the front of the processing platform 2 corresponding to the position of the pull rod 5, and one end of the pull rod 5 is located inside the through groove. In addition, the front end of the spring 4 is welded to the outer wall of the through groove. Positioning insertion holes 15 are provided longitudinally at equal intervals on the surface of the pull rod 5. The guide sleeve 9 is set above the positioning hole 3 and is vertically aligned with the hole position of the positioning hole 3.

[0026] Its adoption is as follows Figure 1 The technical solution shown has a equidistant design for the positioning holes 15. After the pull rod 5 is stretched, the positioning rod is inserted into the positioning hole 15 to limit and lock the pull rod 5 and the arc-shaped clamp 6. This allows for adjustment of the position of the arc-shaped clamp 6 and facilitates the insertion of the elastic pin into the positioning hole 3. A guide sleeve 9 is set above the drilling position and aligned with the hole of the elastic pin to ensure that the drilling tool remains vertical during processing. Example

[0027] This utility model is as follows Figures 1-4 As shown, the clamping part of the arc-shaped clamping plate 6 is bonded with a rubber gasket, the elastic gasket 7 is arc-shaped and adapted to the arc-shaped clamping plate 6; the spring 4 is wrapped around the outside of the pull rod 5, and the bottom of the arc-shaped clamping plate 6 is in contact with the inner wall of the positioning hole 3.

[0028] Using the above technical solution, the spring 4 is a spiral design, which can open and tighten one end of the pull rod 5 and reinforce the external compression of the arc-shaped clamp 6, so as to increase the firmness of the elastic pin after vertical installation inside the positioning hole 3. The spring clamp is used to provide continuous clamping force to prevent the elastic pin from loosening during processing.

[0029] The working principle of this utility model is as follows: the elastic pin is vertically inserted into the positioning hole 3, and then the limit on the pull rod 5 is released. The tension of the spring 4 drives the pull rod 5 to move inward, and the arc-shaped clamp 6 is clamped on the front of the elastic pin, while the back of the elastic pin is attached to the inside of the elastic pad 7 to complete all-round reinforcement. Then, the position of the guide sleeve 9 is adjusted by rotating the adjusting screw 11, and the guide sleeve 9 is moved to the top of the positioning hole 3 and aligned. The drilling tool passing through the guide sleeve 9 can ensure that the drilling tool remains vertical during the processing and can also prevent the elastic pin from shifting.
