Description

Technical Field

[0001] This utility model relates to the technical field of aviation plug processing equipment, and in particular to a positioning structure for laser engraving of aviation plug pins. Background Technology

[0002] Aviation connectors are commonly used in complex equipment, such as military, aerospace, and industrial equipment, to ensure the safety and reliability of connections. During the manufacturing process of aviation connectors, laser engraving is sometimes required on the pins. For example, laser engraving can mark different numbers at corresponding positions on the pins to distinguish specifications (such as size) and avoid incorrect installation, or it can support identification codes on the pins for easy scanning and traceability.

[0003] As attached Figure 9 As shown, the body of the insert 100 has a cavity 101 and a socket 102 that is perpendicularly connected to the cavity. The position that needs to be laser engraved is located on the side wall opposite to the socket 102. Conventional clamping and positioning makes it difficult to accurately align the position that needs to be laser engraved with the laser engraving equipment, and it is also difficult to position the insert 100 in batches, which affects the processing accuracy and processing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning structure for laser engraving of aviation plug pins. By supporting the pin with a support plate, the upper end of the pin can protrude from the upper surface of the positioning plate to horizontally position the pin. By translating the substrate, the vertical hole and the clearance space are aligned so that the pin and the pin can move down and the pin can fall into the contour groove. This can achieve precise positioning of the pin and facilitate laser engraving after precise positioning.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a positioning structure for laser engraving of aviation plug pins, comprising:

[0006] The positioning plate has multiple parallel bottom grooves at its lower end. The positioning plate also has multiple vertical holes arranged in a matrix, penetrating its body and communicating with the bottom grooves. The upper end of the positioning plate has a contoured groove communicating with the vertical holes for horizontally embedding the lower part of the pin.

[0007] The base plate includes a base plate and a support plate disposed on the base plate and matching the number of bottom grooves. The base plate has a clearance space on one side of the support plate. The base plate abuts against the lower end of the positioning plate, and the base plate slides relative to the positioning plate such that the support plate and the clearance space are respectively located below the vertical holes.

[0008] The ejector pin is disposed in the vertical hole and can slide up and down. When the lower end of the ejector pin abuts against the support plate, its upper end protrudes out of the positioning plate. When the lower end of the ejector pin is located in the clearance space and abuts against the substrate, its upper end is located in the contour groove.

[0009] As a further optimization, the upper end of the support plate is provided with a transition slope on the side near the clearance space, which can make the ejector pin move more smoothly on the support plate into the clearance space, and can also make the ejector pin positioned at a certain height during the downward movement.

[0010] As a further optimization, the transition slope extends from the support plate to the substrate.

[0011] As a further optimization, the clearance space is provided with an elastic support with a perforated structure. The elastic support is located on one side of the support plate and abuts against it. The upper surface of the elastic support is lower than the plane where the lowest point of the support plate is located.

[0012] As a further optimization, the elastic support is bonded to the substrate.

[0013] As a further optimization, a slot is provided on the base plate within the clearance space, and the lower end of the elastic support is embedded in the slot. The elastic support can be easily adjusted and replaced by engaging with the slot.

[0014] As a further optimization, the elastic support is a sponge.

[0015] As a further optimization, both the upper and lower ends of the ejector pin are arc-shaped, which facilitates the ejector pin to be inserted into the insertion port of the insert pin, or embedded into the elastic support, or to be moved horizontally on the support plate.

[0016] As a further optimization, when the substrate abuts against the lower end of the positioning plate, there is a gap between the upper end of the support plate and the top wall of the bottom groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By supporting the ejector pin with the support plate, the upper end of the ejector pin protrudes from the upper end of the positioning plate to horizontally position the insertion pin. After the vertical hole and the clearance space are aligned by the translation of the base plate, the ejector pin and the insertion pin move down so that the insertion pin falls into the contour groove. This can achieve precise positioning of the insertion pin and facilitate laser engraving after precise positioning.

[0019] 2. It facilitates the synchronous positioning of multiple pins, which can improve processing efficiency. Attached Figure Description

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figures 1 to 4As shown, a positioning structure for laser engraving of aviation plug pins includes a positioning plate 10, a ejector pin 20, and a base plate 30. The lower end of the positioning plate 10 has multiple parallel bottom grooves 11, such as three bottom grooves 11. The positioning plate 10 has multiple vertical holes 12 arranged in a matrix, penetrating its body and communicating with the bottom grooves 11, such as eight vertical holes 12 corresponding to each bottom groove 11. The upper end of the positioning plate 11 has a contoured groove 13 communicating with the vertical holes 12 for horizontally embedding the lower part of the ejector pin. The base plate 30 includes a base plate 31 and support plates 32 disposed on the base plate 31 and matching the number of bottom grooves 11, i.e., three support plates 32 are provided. The support plate 32 and the base plate 31 have a clearance space 320 on one side of the support plate 32, that is, the width of the support plate 32 is less than the width of the bottom groove 11. The base plate 31 abuts against the lower end of the positioning plate 10, and the base plate 31 slides relative to the positioning plate 10 so that the support plate 32 and the clearance space 320 are respectively located below the vertical hole 12. The ejector pin 20 can slide up and down in the vertical hole 12. When the lower end of the ejector pin 20 abuts against the support plate 32, the upper end of the ejector pin 20 protrudes out of the positioning plate 10. When the lower end of the ejector pin 20 is located in the clearance space 320 and abuts against the base plate 31, the upper end of the ejector pin 20 is located in the contour groove 13.

[0031] In this utility model, the object requiring laser engraving is the pin 100 of the aviation connector (e.g., Figure 9 As shown, the basic structure of the insert 100 body includes a cavity 101 and a socket 102 that passes through the side wall of the insert 100 and is perpendicularly connected to the cavity 101. Laser engraving is required on the outer side wall of the insert 100 opposite to the socket 102. When applying this invention, firstly, the positioning plate 10 is placed against the base plate 31, and the support plate 32 extends upward into the bottom groove 11, with the support plate 32 located below the vertical hole 12. Multiple ejector pins 20 are then inserted downward from above the positioning plate 10 into the contour groove 13, so that after passing through the vertical hole 12, the lower end of the ejector pin 20 abuts against the upper end of the support plate 32. In this state, the ejector pin 20 is supported by the support plate 32, and its upper end protrudes from the upper surface of the positioning plate 10. By setting the ejector pins… The ejector pin 20 has a certain length, allowing its upper part to protrude beyond the upper surface of the positioning plate 10. Therefore, multiple insert pins 100 can be respectively fitted onto the upper end of the ejector pin 20 through their respective insertion ports 102, and the upper end of the ejector pin 20 can extend into the cavity 101. Since the cavity 101 has a certain diameter, after the end of the ejector pin 20 abuts against the side wall of the cavity 101 opposite to the insertion port 102, the insert pin 100 can be positioned horizontally at the upper part of the ejector pin 20 (e.g., ...). Figure 7As shown), after the ejector pin 20 provides horizontal support to the insert pin 100, the positioning plate 10 or the base plate 31 is moved so that the clearance space 320 located beside the support plate 32 is below the vertical hole 12. The lower end of the ejector pin 20 then falls due to loss of support, causing it to displace vertically downwards within the vertical hole 12 until its lower end abuts against the base plate 31, and its upper end is located within the contour groove 13. During this process, the insert pin 100 located above the ejector pin 20 also moves downwards, and at least partially of its lower part falls into the contour groove 13. The insert pin 100 remains positioned relative to the upper part of the ejector pin 20 through its cavity 101 and insertion port 102 (as shown). Figure 8 As shown), through the above structure and operation, the pins 100 can be positioned in the vertical and horizontal directions. That is, multiple pins 100 can be positioned in the same horizontal posture so that the side of the pin 100 opposite to the socket 102 is above. After the positioning structure is placed on the laser engraving equipment (the positioning structure can be moved forward, backward, left and right on the moving module of the laser engraving equipment), it is convenient for multiple pins to be laser engraved in batches. After the pins 100 have completed the laser engraving, the base plate 30 is detached from the lower end of the positioning plate 10, and the pins 20 protruding from the bottom groove 11 are removed. Then, the pins 20 can be easily taken out from the contour groove 12.

[0032] It should be noted that the connection between the insert pin 100 and the ejector pin 20 is not an interference fit, but a sleeve fit. That is, the insert pin 100 can rotate relative to the ejector pin 20, which facilitates the installation of the insert pin 100 on the ejector pin 20 and the removal of the ejector pin 20 from the insert pin 100. Therefore, when the ejector pin 20 is lifted by the support plate 32, the state of the insert pin 100 after it is installed on the upper part of the ejector pin 20 needs to be adjusted. That is, by fine-tuning the rotation of the insert pin 100 relative to the ejector pin 20, the vertical projection of the insert pin 100 can fall into the contour groove 13, so that the insert pin 100 can fall into the contour groove 13 after the ejector pin 20 moves down.

[0033] This invention supports the ejector pin 20 via the support plate 32, allowing the upper end of the ejector pin 20 to protrude from the upper surface of the positioning plate 10. This facilitates the insertion pin 100 to be horizontally fitted onto the ejector pin 20 through its insertion port and cavity. Then, by translating the base plate 31, the vertical hole 12 aligns with the clearance space 320, allowing the ejector pin 20 and insertion pin 100 to move downwards and the insertion pin 100 to fall into the contour groove 13. The ejector pin 20 remains connected to the insertion pin 100 while being supported by the base plate 31, enabling precise positioning of the insertion pin 100. This facilitates laser engraving after precise positioning and allows for simultaneous positioning of multiple insertion pins, thereby improving processing efficiency.

[0034] After the insert pin 100 is installed on the ejector pin 20 and its position is adjusted (so that its horizontal position is opposite to the contour groove 13), during the downward movement of the ejector pin 20 and the insert pin 100, the insert pin 100 may not be completely aligned with the contour groove 13, or the insert pin 100 may shift during the downward movement, which may result in the insert pin 100 not falling completely into the contour groove 13. Figure 4 As shown, in one embodiment of this utility model, a transition slope 321 is provided on the upper end of the support plate 32 near the clearance space 320. Through the function of the transition slope 321, the ejector pin 20 and the insert pin 100 can not move down quickly, but can move down slowly to a certain height. When the insert pin 100 is located at a height position closer to the contour groove 13, the horizontal state of the insert pin 100 is further adjusted to ensure that the insert pin 100 can be completely aligned with the contour groove 13.

[0035] Preferably, the transition slope 321 extends from the support plate 32 to the substrate 31, which can realize the slow downward movement of the ejector pin 20 and the insert pin 100, and can adjust the horizontal state of the insert pin 100 at a position closer to the contour groove 13.

[0036] In the above embodiments, on the one hand, adjusting the state of the pin 100 at a certain height may not completely achieve alignment with the contour groove 13; on the other hand, the multiple ejector pins 20 (and the multiple pins 100 located thereon) have synchronous downward movement, and adjusting one pin 100 may affect (e.g., accidentally touch) the state of adjacent pins 100. Therefore, it is preferable to be able to control the downward movement process of each pin 100 individually. Based on the above reasons, as... Figure 5As shown, in one embodiment of this utility model, an elastic support 33 with a perforated structure is provided in the clearance space 320. The elastic support 33 has a perforated structure, can deform, and can return to its original shape. For example, it can be a sponge structure. When a pin 20 is inserted into it, it can maintain the state of the pin 20, and the position of the pin 20 will not change when no external force is applied. The elastic support 33 is located on one side of the support plate 32 and abuts against it. The upper end surface of the elastic support 33 is lower than the plane of the lowest point of the support plate 32. Through the setting of the elastic support 33, after the relative displacement of the positioning plate 10 and the base plate 31 (the vertical hole 12 is opposite to the clearance space 320), the lower end of the pin 20 is moved by the perforated structure. The support plate 32 is now supported by an elastic support 33, which supports the ejector pin 20 and the insert pin 100 (the small mass prevents the lower end of the ejector pin 20 from embedding into the elastic support 33) and maintains this support state. Therefore, the operator can press down the insert pin 100 one by one to embed the ejector pin 20 into the elastic support 33, and adjust the state of the insert pin 100 during the pressing process to ensure complete alignment with the contour groove 33. This allows for the individual pressing and adjustment of the insert pin 100. After laser engraving is completed, when the base plate 30 is removed downwards, the ejector pin 20 can be removed simultaneously because its lower part is embedded in the elastic support 33. Then, the ejector pins 20 can be removed one by one from the elastic support 33. Although each insert pin 100 is operated on individually in this embodiment, the alignment accuracy between the insert pin 100 and the contour groove 13 is improved during the operation, and mutual interference between operations on different insert pins 100 is avoided. This does not affect the positioning efficiency of multiple insert pins 100.

[0037] The elastic support 33 can be mounted on the substrate; for example... Figure 6 As shown, in one embodiment, a slot 310 is provided on the base plate 30 within the clearance space 320, that is, a slot 310 is provided on the base plate 31. The lower end of the elastic support 33 is embedded in the slot 310, which facilitates the installation and replacement of the elastic support 33. If the structure of the elastic support 33 becomes loose to a certain extent after being embedded in the ejector pin 20 multiple times, it can be taken out, flipped, and re-embedded in the slot 310, or a new elastic support 33 can be replaced and embedded in the slot 310.

[0038] Preferably, both the upper and lower surfaces of the ejector pin 20 are arc-shaped, which facilitates its insertion into the socket 102 of the insert pin 100 and the elastic support 33. The arc-shaped lower surface also helps to ensure the smoothness of the ejector pin 20 when it moves relative to the support plate 32 and / or the elastic support 33.

[0039] In addition, by setting the height of the support plate 32, when the base plate 31 abuts against the lower end of the positioning plate 10, there is a gap between the upper end of the support plate 32 and the top wall of the bottom groove 11. That is, when the lower end of the ejector pin 20 abuts against the support plate 32, the position of the vertical hole 12 can position the lower middle or middle part of the ejector pin 20, which can avoid the phenomenon that the vertical state of the ejector pin is unstable due to only being able to position the lower part of the ejector pin 20.

[0040] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
