Description

Technical Field

[0001] This utility model relates to the field of product stamping technology, and in particular to upsetting tooling. Background Technology

[0002] Aerospace-grade quick-release locks are equipped with pin locks, and the size of the pin in these pin locks is a crucial factor that directly affects the working performance of the pin locks.

[0003] To ensure the upset dimensions of the pins, strict control of the upset time and upset force is required, which demands high precision. However, a pin-locking rivet has two pins positioned opposite each other. This means each pin-locking rivet requires two upset processes. In other words, machining one pin-locking rivet necessitates repeated clamping, positioning, and upseting, significantly reducing the overall machining efficiency.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0014] A further technical solution is that a sliding plate is provided at the end of the baffle away from the unloading block; when the pin is set on the baffle; the sliding plate is engaged in the slot of the pin; the sliding plate can slide on the baffle along the axial direction of the guide post.

[0015] A further technical solution is that a T-shaped groove is provided on the baffle along the axial direction of the guide post; the slide is connected to a T-shaped rod; the slide is slidably connected to the baffle through the T-shaped groove and the T-shaped rod.

[0016] A further technical solution is that an upper upsetting block is provided on the upper cover plate, and a lower upsetting block is provided on the lower cover plate; the upsetting holes are respectively opened on the upper upsetting block and the lower upsetting block.

[0017] A further technical solution is that the upsetting hole includes a constant diameter section and a reaming section; the reaming section is located at the opening of the upsetting hole; along the axial direction of the upsetting hole, towards the opening of the upsetting hole, the diameter of the upsetting hole in the reaming section gradually increases.

[0018] A further technical solution is that a limiting rod is also provided in the unloading hole; the limiting rod is inserted into the unloading hole from the end of the unloading block away from the pin locking pin.

[0019] A further technical solution is that an internal thread is provided in the discharge hole; an external thread is provided on the limiting rod; and the limiting rod is threadedly connected to the discharge hole.

[0020] A further technical solution is that two guide posts are arranged in parallel.

[0021] The beneficial technical effects of this utility model are as follows:

[0022] (1) The upsetting fixture in this utility model upsets the pins by closing the upper and lower cover plates. Because the upper and lower cover plates are respectively provided with upsetting holes, the two pins on the pin lock can be processed simultaneously by closing the upper and lower cover plates at one time, eliminating the need for repeated clamping, positioning and upsetting steps, and greatly improving the processing efficiency of the pin lock. A stripper block is set between the upper and lower cover plates to fix the position of the pin lock. Elastic elements are also set on the guide posts between the stripper block and the upper cover plate, and between the stripper block and the lower cover plate. When upsetting, the upper cover plate is squeezed, and the elastic elements are compressed and push the stripper block to move. The elastic force between the two elastic elements is balanced, so that the stripper block between the upper and lower cover plates is automatically centered. That is, the distance between the pin lock inserted into the stripper hole and the upper and lower cover plates is always the same. Ensure that the upsetting stroke of the two pins on the locking pin is the same during upsetting, thereby ensuring that the upsetting effect of the two pins is consistent.

[0023] (2) Furthermore, the baffle is provided with a limiting groove and a sliding groove. The sliding groove restricts the lateral position of the pin lock, and the limiting groove restricts the orientation of the pin on the pin lock, so as to quickly position the pin lock and simplify the assembly process.

[0024] (3) Furthermore, a sliding plate is still provided on the baffle. The sliding plate engages with the slot of the pin locking pin to restrict the rotation of the pin locking pin. This prevents the pin locking pin from rotating around itself in the sliding groove during upsetting, thus avoiding misalignment of the upsetting hole with the pin. The sliding plate can conveniently restrict the orientation of the pin, facilitating the upsetting process. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0035] Figure 1 A front view structural schematic diagram of an upsetting tool according to an embodiment of the present disclosure is shown. Figure 2 A left-side structural schematic diagram of an upsetting fixture according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 2The upsetting fixture includes an upper cover plate 1 and a lower cover plate 2. Upsetting holes 12 are respectively provided on the upper cover plate 1 and the lower cover plate 2. These holes restrict the upsetting dimensions of the pin 71, preventing bending and end deformation, thus improving the dimensional accuracy of the upsetting pin 71. The two upsetting holes 12 are arranged facing each other. The pin 71 is upset by closing the upper cover plate 1 and the lower cover plate 2. Because the upper cover plate 1 and the lower cover plate 2 are respectively provided with upsetting holes 12, closing the upper cover plate 1 and the lower cover plate 2 once allows simultaneous processing of two pins 71 on the pin-locking 7, eliminating the need for repeated clamping, positioning, and upsetting steps, greatly improving the processing efficiency of the pin-locking 7. A guide post 4 passes through both the upper cover plate 1 and the lower cover plate 2, restricting the trajectory of the upper cover plate 1 and the lower cover plate 2 during vertical movement. A stripper block 3 is positioned between the upper cover plate 1 and the lower cover plate 2. The unloading block 3 has an unloading hole 31. A guide post 4 also passes through the unloading block 3. Elastic elements 41 are respectively provided on the guide posts 4 between the unloading block 3 and the upper cover plate 1, and between the unloading block 3 and the lower cover plate 2. During upsetting, the pin 7 is inserted into the unloading hole 31, and the position of the pin 7 is fixed by the unloading block 3. While the upper cover plate 1 is being pressed during upsetting, the elastic elements 41 are compressed, pushing the unloading block 3 to move. The elastic forces between the two elastic elements 41 are balanced, causing the unloading block 3 between the upper cover plate 1 and the lower cover plate 2 to automatically center. That is, the distance from the pin 7 inserted in the unloading hole 31 to the upper cover plate 1 and the lower cover plate 2 is always the same. This ensures that the upsetting stroke of the two pins 71 on the pin 7 is the same during upsetting.

[0036] Preferably, two guide posts 4 are arranged in parallel. Compared to a single guide post 4 restricting the lateral movement of a part, two guide posts 4 restrict the lateral movement of a part while also restricting its rotation around the guide posts 4. When the upper cover plate 1, lower cover plate 2, and unloading block 3 move along the guide posts 4, the two guide posts 4 can also distribute the force, reducing the risk of overload on the guide posts 4 and improving guiding accuracy.

[0037] Figure 3 The diagram shows a front view of the baffle in an upsetting fixture according to an embodiment of the present disclosure. Figure 4 This diagram illustrates a top view of an upsetting fixture according to an embodiment of the present disclosure, showing the baffle positioned at the T-slot. Please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 It also includes a baffle 5. The baffle 5 is located at the end of the upper cover plate 1 or the lower cover plate 2 away from the unloading block 3. A groove 51 is provided on the baffle 5, which is parallel to the guide post 4. The pin 7 is inserted into the unloading hole 31 along the groove 51. The groove 51 restricts the lateral position of the pin 7, thereby improving the stability of the pin 7 during the upsetting process.

[0038] Preferably, a limiting groove 52 is also provided on the baffle 5. The limiting groove 52 is connected to the slide groove 51. The limiting groove 52 is provided along the axial direction of the guide post 4. When the pin 7 passes through the slide groove 51, the pin 71 of the pin 7 passes through the baffle 5 along the limiting groove 52. The limiting groove 52 restricts the orientation of the pin 71 on the pin 7, so as to quickly position the orientation of the pin 71 on the pin 7 and simplify the assembly process.

[0039] More preferably, a sliding piece 55 is also provided at the end of the baffle 5 away from the unloading block 3. When the pin 7 is set on the baffle 5, the sliding piece 55 engages with the slot 72 of the pin 7. The engagement between the sliding piece 55 and the slot 72 of the pin 7 restricts the rotation of the pin 7. Even if the pin 7 slides in the slide groove 51, the pin 7 will not rotate and change the orientation of the pin 71, thus preventing the pin 7 from rotating when moving along the slide groove 51, which would cause the upsetting hole 12 to not align with the pin 71 and affect the upsetting process. The sliding piece 55 can slide on the baffle 5 along the axial direction of the guide post 4. Specifically, a T-slot 53 is provided on the baffle 5 along the axial direction of the guide post 4. The sliding piece 55 is connected to a T-shaped rod 54. The T-shaped rod 54 engages with the T-shaped groove 53, allowing the slider 55 to slide only along the length of the T-shaped groove 53. Through the T-shaped groove 53 and the T-shaped rod 54, the slider 55 is slidably connected to the baffle 5.

[0040] Figure 5 A partially enlarged view of the upsetting tooling at point A according to an embodiment of the present disclosure is shown. Figure 6 A schematic diagram of the pin locking pin according to an embodiment of the present disclosure is shown in the front view direction. Please refer to... Figure 1 , Figure 2 , Figure 5 and Figure 6 The upper cover plate 1 is provided with an upper upsetting block 11, and the lower cover plate 2 is provided with a lower upsetting block 21. Upsetting holes 12 are respectively opened on the upper upsetting block 11 and the lower upsetting block 21. The upper upsetting block 11 is connected to the upper cover plate 1 by a threaded fastener 6, and the lower upsetting block 21 is connected to the lower cover plate 2 by a threaded fastener 6. When the size of the pin locking 7 changes, only the upper upsetting block 11 and the lower upsetting block 21 need to be replaced, without adjusting or disassembling the upper cover plate 1 and the lower cover plate 2, thus enhancing the versatility of the upsetting tooling.

[0041] Preferably, the upsetting hole 12 includes a constant diameter section 121 and a reaming section 122. The reaming section 122 is located at the opening of the upsetting hole 12. Along the axial direction of the upsetting hole 12, the diameter of the upsetting hole 12 within the reaming section 122 gradually increases towards the opening of the upsetting hole 12. The reaming section 122 provides a margin for upsetting the pin 71.

[0042] Please refer to Figure 1 and Figure 2A limiting rod 32 is also provided inside the discharge hole 31. The limiting rod 32 is inserted into the discharge hole 31 from the end of the discharge block 3 away from the pin 7. By adjusting the depth of the limiting rod 32 into the discharge hole 31, the depth of the pin 7 into the discharge hole 31 can be easily adjusted.

[0043] Preferably, the discharge hole 31 is provided with an internal thread. The limiting rod 32 is provided with an external thread. The limiting rod 32 is threadedly connected to the discharge hole 31. The threaded connection has high strength and stability, and by rotating the limiting rod 32, the depth of the limiting rod 32 extending into the discharge hole can be conveniently and accurately adjusted.

[0044] The specific workflow of this utility model is as follows:

[0045] When upsetting the pin 7, first rotate the limiting rod 32 to adjust the depth of the limiting rod 32 into the unloading hole 31. Then, the pin 7 to be upset passes through the baffle 5 along the slide groove 51, and the pin 71 passes through the baffle 5 along the limiting groove 52, until the pin 7 extends into the unloading hole 31 and contacts the limiting rod 32. Press the upper cover plate 1, and the upper cover plate 1 pushes the unloading block 3 along the guide post 4 along the elastic member 41 until the pin 71 extends into the upsetting hole 12 and is upset. Finally, stop pressing the upper cover plate 1, and the elastic member 41 drives the upper cover plate 1 and the unloading block 3 to reset, remove the pin 7, and the upsetting is completed.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
