Abstract
Description
Technical Field
[0001] This application relates to the field of connector manufacturing equipment technology, and in particular to a PIN bending fixture. Background Technology
[0002] A connector is a device used to connect two active devices, consisting of a plastic component and pins. The pins are metallic components used in connectors to transmit electrical signals and conduct electricity. Due to the evolving needs of electronic components, an increasing number of connector pins require bending operations.
[0003] In existing related technologies, the connector pin bending fixture is used for bending. First, the pressure block of the fixture is raised, then the connector is placed in a fixed position, and finally the pressure block is used to fix the plastic part of the connector in the vertical direction, so that the plastic part is not easy to shake during the bending process of the pin.
[0004] Regarding the aforementioned technologies, the clamping block can easily obstruct the placement of the connector, making it inconvenient to place the connector pins. Summary of the Invention
[0005] To address the aforementioned technical problems, this application provides a PIN bending fixture.
[0006] The PIN bending fixture provided in this application adopts the following technical solution:
[0007] A PIN bending fixture includes a mounting frame, a PIN fixing assembly, a pressing assembly, and a PIN bending assembly.
[0008] The PIN pin fixing assembly is used to place the connector and is slidably mounted on the mounting frame in the horizontal direction. The pressing assembly is used to fix the connector in the vertical direction and is mounted on the mounting frame. The PIN pin bending assembly is used to bend the PIN pin and is mounted on the mounting frame.
[0009] By adopting the above technical solution, when connectors need to be loaded and unloaded, the PIN pin fixing component is slid horizontally to a suitable position on the mounting frame to avoid the pressure block obstructing the placement of the connector. At the same time, it is easy to observe the placement position of the PIN pins, thus realizing convenient loading and unloading of the connectors. Then, the connector is fixed below with the pressing component to prevent the connector PIN pins from shaking when bent. Finally, the PIN pin bending component completes the bending of the connector PIN pins.
[0010] Optionally, the PIN pin fixing assembly includes a placement member and a seat driving member. The placement member has a receiving cavity for accommodating the plastic part, and the seat driving member is used to drive the placement member to move in a horizontal direction.
[0011] By adopting the above technical solution, the plastic parts are fixed in the accommodating cavity during connector loading and unloading, which avoids positional displacement when the connector is slid after loading. The placement part is driven to move horizontally away from the pressure block by the seat drive, which facilitates the placement and observation of the connector.
[0012] Optionally, the PIN bending assembly includes a pressing component and a rotating shaft drive component. The pressing component is rotatably fitted to the mounting frame, and the rotating shaft drive component is used to drive the pressing component to rotate.
[0013] By adopting the above technical solution, the rotating shaft drive can drive the pressing component, which can achieve stable bending of the PIN pin and facilitate the adjustment of the bending angle of the PIN pin according to the connector specifications.
[0014] Optionally, the pressing component includes a PIN bending block and a rotating shaft plate, wherein the PIN bending block has a slot for the PIN to pass through.
[0015] By adopting the above technical solution, the PIN pin passing through the slot can fully increase the force-bearing area, reduce uneven force when the PIN is bent, achieve stable bending of the PIN pin, and reduce the occurrence of wobbling of the PIN pin during the bending process.
[0016] Optionally, the PIN bending block can be detachably installed on the rotating shaft plate.
[0017] By adopting the above technical solution, PIN bending can be achieved conveniently and efficiently by replacing the rotating plate when dealing with PINs of different specifications.
[0018] Optionally, the placement component includes a placement seat and a clamping block, with a receiving cavity formed between the placement seat and the clamping block for accommodating the plastic part, and the clamping block being horizontally movable and fitted to the placement seat.
[0019] By adopting the above technical solution, when it is necessary to replace different types of connectors, the position between the clamps can be adjusted to accommodate plastic parts of different sizes, thus achieving more efficient connector loading and unloading.
[0020] Optionally, the placement seat can be adjusted in the vertical direction.
[0021] By adopting the above technical solution and adjusting the height of the placement base, it is ensured that the connector PIN can be accurately embedded in the hole slot opened by the PIN pin bend.
[0022] Optionally, the rotating shaft plate is provided with a sliding groove for the PIN bending block to slide.
[0023] By adopting the above technical solution, the need for secondary calibration of the connector position due to positional errors during connector fixing is reduced, thus enabling flexible adjustment.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] 1. The horizontally sliding connector loading and unloading cavity on the mounting frame makes it easier to load and unload connectors, does not obstruct the placement of connector pins, and makes it easier to observe the placement of pins.
[0026] 2. The connector is fixed vertically by the upper pressure block, and the holes and grooves on the PIN bending block are used to fully increase the contact area of the PIN pin, so that the PIN pin can be bent stably and neatly.
[0027] 3. The flexible adjustment in both horizontal and vertical directions allows for compatibility with a wider range of connector specifications.
[0028] 4. The horizontal sliding loading and unloading cavity design of the mounting frame significantly improves the operability of connector placement and PIN pin fixation, avoids interference and facilitates observation. Combined with the vertical pressing of the pressing component and the contact support of the PIN pin by the hole groove of the PIN pin bending block, bending stress is effectively dispersed, ensuring consistent bending angle and pin integrity. At the same time, by adjusting the height of the placement seat, adjusting the spacing of the clamping blocks, and replacing the PIN pin bending blocks, flexible adaptation in both horizontal and vertical directions can be achieved, which is compatible with connectors of different sizes and heights and various PIN pin bending specifications, greatly expanding the versatility and processing accuracy of the fixture.

[0038] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.
[0039] Example 1:
[0040] Embodiment 1 of this application discloses a PIN bending fixture. (Refer to...) Figure 1 The PIN bending fixture includes a mounting frame, a PIN fixing component 1, a pressing component 2, and a PIN bending component 3.
[0041] Reference Figure 2 The PIN pin fixing component is slidably mounted on the mounting frame. The PIN pin fixing assembly 1 includes a placement component and a seat drive component 11. The placement component includes a placement seat 12 and clamping blocks 13. The placement seat 12 slides along the first horizontal direction and engages with the mounting frame via guide rails on both sides, and both guide rails are fixedly mounted on the bottom of the mounting frame. There are two clamping blocks 13, both located on top of the placement seat 12 and facing each other. A receiving cavity 101 for placing the connector is formed between the clamping blocks 13. When the connector is placed in the receiving cavity 101, the inner walls of the receiving cavity 101, that is, the surfaces of the two clamping blocks 13, are tightly fitted to the plastic parts of the connector. This ensures that the connector remains stable during the sliding movement of the placement seat 12 after loading, and during bending of the PIN pin, thereby reducing the occurrence of deviation in the position of the PIN pin due to vibration after loading.
[0042] The seat drive 11 is used to drive the placement seat 12 to slide horizontally along the guide rail. The seat drive 11 can be a cylinder or a motor, and in Embodiment 1 of this application, the seat drive 11 is a cylinder, with the cylinder body and piston rod of the seat drive 11 fixedly mounted on the mounting frame and the placement seat 12, respectively. During loading, the seat drive 11 drives the placement seat 12 to move along the guide rail, ensuring sufficient placement space at the top of the receiving cavity 101. This reduces the adverse effects on connector placement caused by limited placement space, thereby facilitating connector loading and unloading.
[0043] Reference Figure 3 The pressing assembly 2 includes a pressing block 21 and a pressing drive 22. The pressing block 21 slides vertically and engages with the mounting frame. The pressing drive 22 drives the pressing block 21 to move vertically. When the connector placed on the placement base 12 moves horizontally below the pressing block 21, the pressing drive 22 drives the pressing block 21 to press against the connector. This, combined with the two clamping blocks 13, keeps the connector stable in both the horizontal and vertical directions, reducing connector wobbling.
[0044] Reference Figure 4 The PIN bending assembly 3 includes a pressing component and a rotating shaft drive component 33. The pressing component includes a PIN bending block 31 and a rotating shaft plate 32. The rotating shaft plate 32 is rotatably fitted to the mounting frame and is fixedly connected to a transmission gear 321. The output end of the rotating shaft drive component 33 can be a cylinder or a motor. In Embodiment 1 of this application, the rotating shaft drive component 33 is a cylinder, and the cylinder body and piston of the rotating shaft drive component 33 are respectively fixedly installed on the mounting frame and the rack 331. The rotation and reset of the rotating shaft plate 32 are achieved through the rack 331, thereby realizing the bending of the PIN pin. The PIN bending block 31 has several holes and slots 311 for the PIN pin to pass through horizontally, so that the PIN pin is not easily deflected during the bending process. The PIN bending block 31 is detachably installed on the rotating shaft plate 32, so as to facilitate the replacement of the PIN bending block 31 according to the specifications of the connector to be bent, thereby facilitating the bending operation of PIN pins of various connector specifications. Specifically, in Embodiment 1 of this application, the PIN bending block 31 is bolted to the rotating shaft plate 32 to ensure connection stability and facilitate disassembly and replacement.
[0045] The implementation principle of Embodiment 1 of this application is as follows:
[0046] S1. Drive the placement seat 12 away from the pressing assembly 2 in the second horizontal direction along the guide rail via the seat drive component 11;
[0047] S2. Adjust the position of the stop block 14 on the placement seat 12 according to the length requirement of the bent PIN pin by adjusting the bolt of the second adjustment hole 141;
[0048] S3. Place the connector into the receiving cavity 101 of the placement seat 12, and fix the connector on the placement seat 12 by adjusting the bolt adjustment block 13 of the first adjustment hole 131.
[0049] S4. The drive body drive component 11 drives the placement seat 12 to move along the guide rail in the second horizontal direction and approach the lower pressure component 2.
[0050] S5. Adjust the height adjustment block 15 so that the PIN pin is inserted into the slot 311 of the PIN pin bending block 31;
[0051] S6. The pressure block 21 is pressed against the connector by the pressure drive 22;
[0052] S7. Drive the rotating shaft plate 32 to perform the operation of bending the PIN pin by the rotating shaft drive component 33;
[0053] S8. The rotating shaft plate 32 is reset to the initial angle by the reverse drive component 33.
[0054] Therefore, this application uses a cylinder to drive the placement seat 12 of the fixed connector to move along the guide rail to the pressure block 21 that fixes the connector in the vertical direction, so that there is enough placement space above when loading and unloading, and it is easy to observe the position of the connector, thus facilitating the loading and unloading of the connector. The clamping block 13 set on the top of the placement seat 12 is used to fix the connector, reducing the shaking of the connector when moving along the guide rail.
[0055] Adjusting the vertical height of the placement seat 12, in conjunction with the position of the clamping block 13 and the PIN bending block 31 in the horizontal direction of the rotating shaft plate 32, allows the PIN pin to be accurately embedded into the hole groove 311 of the PIN bending block, increasing the force-bearing area when the PIN pin is bent, and further stabilizing the PIN pin in the horizontal direction.
[0056] Finally, the connector is pressed against the pressure block 21, and the two clamping blocks 13 keep the connector stable in the horizontal and vertical directions. The rotating shaft plate 32 is driven to rotate by the rotating shaft drive 33, so that the PIN bending block 31 bends the PIN of the connector and reduces the shaking when bending the PIN.
[0057] Example 2:
[0058] Embodiment 2 of this application discloses a PIN bending fixture.
[0059] The main difference between Embodiment 2 and Embodiment 1 of this application is that the specific configuration of the clamping block 13 is different.
[0060] Reference Figure 5The clamping block 13 is slidably fitted onto the placement base 12 to facilitate the fixing of connectors of different specifications, ensuring that when a connector is placed in the accommodating cavity 101, the clamping block 13 can fit tightly against the plastic part of the connector. Specifically, in embodiment 2 of this application, the clamping block 13 has a first adjustment hole 131 extending vertically, and the adjustment hole extends along a second horizontal direction. The clamping block 13 is installed on the placement base 12 by a bolt (not shown in the figure) passing through the first adjustment hole 131, so that the position of the clamping block 13 can be adjusted by turning the bolt when adjustment is needed. It should be noted that in this application, both the first horizontal direction and the second horizontal direction are set along the horizontal direction, and the first horizontal direction is perpendicular to the second horizontal direction.
[0061] Furthermore, Embodiment 2 of this application also includes the following technical features:
[0062] The placement base 12 is slidably provided with a stop block 14 for abutting the connector along the first horizontal direction, so that the connector located in the receiving cavity 101 is more easily kept stable, and the position of the stop block 14 can be adjusted according to the bending length requirements of different connector pins, thereby realizing the movable adjustment of the bending pin length. Specifically, in embodiment 2 of this application, the stop block 14 has a second adjustment hole 141 extending through its own thickness direction. The second adjustment hole 141 extends along the first horizontal direction, and the stop block 14 is installed on the placement base 12 by a bolt (not shown in the figure) passing through the second adjustment hole 141, so that the position of the stop block can be adjusted by turning the bolt when it is necessary to adjust the stop position.
[0063] In addition, in some embodiments, the first adjustment hole 131 and / or the second adjustment hole 141 may be provided on the placement base 12, which will not be described in detail here.
[0064] By limiting the first and second horizontal directions, the size of the receiving cavity 101 for placing the connector is adjusted, so that the connector can be fixed horizontally and the shaking of the connector is reduced.
[0065] Reference Figure 6 and Figure 7Furthermore, the placement base 12 includes a bottom base 121 and a top base 122. The bottom base 121 is slidably fitted to the mounting frame along a second horizontal direction via a guide rail. The top base 122 is located on top of the bottom base 121. The top base 122 is provided with two height adjustment blocks 15. Each height adjustment block 15 has a third adjustment hole 151 extending through it along the second horizontal direction. The third adjustment hole 151 extends vertically, and the height adjustment blocks 15 are installed on the bottom base 121 by several bolts (not shown in the figure) that slide through the third adjustment hole 151. This allows for adjustment of the height of the top base 122 by turning the bolts when adjustment is needed, while ensuring that the height of the top base is consistent. By adjusting the clamping block 13, the connector's pins can be aligned with the slots 311 of the pin bending block 31 in the first horizontal direction. Furthermore, by adjusting the height block 15, the pins can be made to fit vertically into the slots 311, ensuring that the pins fully fit into the slots 311. Finally, the pressing drive 22 drives the pressure block 21 to press the connector firmly, reducing the shaking of the connector's pins during bending.
[0066] Example 3:
[0067] Embodiment 3 of this application discloses a PIN bending fixture, the main difference from Embodiment 1 is that the specific configuration of the rotating plate 32 is different.
[0068] Reference Figure 8 The rotating shaft plate 32 has a sliding groove 322 for the PIN bending block 31 to move in the second horizontal direction, so as to facilitate the adjustment of the PIN bending block 31 in the second horizontal direction. The PIN bending block 31 has a fourth adjustment hole 312, and the PIN bending block 31 is slidably mounted on the rotating shaft plate 32 by a bolt (not shown in the figure) passing through the fourth adjustment hole 312. When the placement seat 12 moves close to the PIN bending block 31 in the first direction via the guide rail, if the PIN of the connector is not aligned with the hole 311 on the PIN bending block 31 in the first horizontal direction, the PIN bending block 31 on the rotating shaft plate 32 is adjusted horizontally by turning the bolt so that the PIN is aligned with the hole 311.
[0069] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
