Description

Technical Field

[0001] This utility model belongs to the field of wire processing, and in particular relates to a cycloidal wire jig. Background Technology

[0002] With the rapid advancement of data center construction, high-speed copper cables, as a key carrier for data transmission, are experiencing increasingly strong market demand. This trend presents greater challenges to the soldering processes of connectors such as PCBs and PCBAs, requiring not only improved soldering precision but also increasingly diverse product forms, often necessitating the soldering of multiple cable specifications onto a single connector.

[0003] Products in this industry typically exhibit "AB-side line symmetry" or "end-point line symmetry." However, existing cycloidal fixture positioning solutions have significant limitations. Current technologies mostly employ a single-head positioning cycloidal mode. When encountering complex scenarios such as symmetrical line positions with multiple wires or non-array spacing line positions, it is necessary to develop two different specifications of first and second positioning seats. Since positioning seats are commonly used basic devices in the industry with high demand, frequent mold opening and production of positioning seats of different specifications will significantly increase manufacturing costs. Furthermore, spare parts management, switching, and debugging will reduce production efficiency, making it difficult to adapt to flexible and diverse production needs. Therefore, a more universal and cost-effective cycloidal fixture positioning solution is urgently needed. Utility Model Content

[0004] The purpose of this invention is to provide a cycloidal fixture to overcome at least one of the above-mentioned defects in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides a cycloidal fixture, including a base, a clamping seat, a first positioning seat, a second positioning seat, and a limiting member. The clamping seat is installed on the base, the first positioning seat is detachably installed on the clamping seat, the second positioning seat is detachably installed on the base, and the limiting member is disposed on the second positioning seat. The first positioning seat has a plurality of spaced first positioning grooves, and the second positioning seat has a plurality of spaced second positioning grooves, with the plurality of first positioning grooves corresponding one-to-one with the plurality of second positioning grooves.

[0007] Preferably, the first positioning seat has a first head, a second head, and a connecting part. The first head and the second head are connected by the connecting part. The top of both the first head and the second head has a plurality of first positioning grooves, and the plurality of first positioning grooves of the first head correspond one-to-one with the plurality of first positioning grooves of the second head.

[0008] Preferably, the top of the connector has a wavy surface.

[0009] Preferably, the first positioning groove includes a first groove and a second groove, with the first groove and the second groove being spaced apart.

[0010] Preferably, there is a drop groove between the first groove and the second groove.

[0011] Preferably, the first positioning seat has a first locking portion, and the clamping seat has a second locking portion that engages with the first locking portion.

[0012] Preferably, it further includes a first bolt, the top of the base has a sliding groove, the second positioning seat slides in conjunction with the sliding groove, the bottom of the sliding groove has a first threaded hole, the front and rear ends of the second positioning seat both have first mounting holes, the first bolt passes through the first mounting hole and is screwed into the first threaded hole to install the second positioning seat on the base, and the second positioning groove passes through the front and rear side walls of the second positioning seat.

[0013] Preferably, the limiting member includes a first limiting strip and a second limiting strip. The first limiting strip is fixed to the top of the second positioning seat and forms a positioning channel with the second positioning groove. The second limiting strip is detachably installed on the top of the second positioning seat and has a stop block at the bottom extending into the second positioning groove.

[0014] Preferably, it further includes a second bolt, the second positioning seat has a plurality of second threaded holes spaced apart front and rear, the second limiting strip has a second mounting hole, the second bolt passes through the second mounting hole and is screwed into the second threaded hole to install the second limiting strip onto the second positioning seat.

[0015] Preferably, the clamping seat includes a base, a cover plate, and a latch. The cover plate is disposed above the first positioning groove, and one end is hinged to one side of the base. The bottom wall of the cover plate is provided with a soft pad. The latch is disposed on the other side of the base for locking the cover plate to press and fix the wire in the first positioning groove.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. With the detachable and reusable first and second positioning seats, only a single specification is needed to meet the requirements of two symmetrical line positions, which greatly reduces mold costs and changeover time. At the same time, the clamping seat stabilizes the wire and the limiting component ensures that the rear end of the wire is flush, which is both versatile and practical.

[0018] 2. The wavy surface is designed to increase the friction force on the wire during the next drawing process after the clamping seat has tightened.

[0019] 3. By setting the drop groove, double-sided tape or sprayed glue can be placed in the drop groove to make it difficult for the wire to come out of the first positioning groove.

[0020] 4. The rear end of the wire is limited by the positioning channel to prevent it from falling out of the second positioning groove.

[0021] 5. The stop block extending from the second limiting strip into the second positioning groove limits the rear end of the wire to ensure that the insertion length of each wire is consistent.

[0022] 6. The position of the second limit bar can be adjusted in the front-to-back direction as needed, thereby adjusting the wire insertion length to adapt to different operational requirements. Attached Figure Description

[0036] like Figures 1 to 10As shown, this embodiment provides a cycloidal jig, including a base 1, a clamping seat 2, a first positioning seat 3, a second positioning seat 4, and a limiting member 5. The clamping seat 2 is mounted on the base 1, the first positioning seat 3 is detachably mounted on the clamping seat 2, the second positioning seat 4 is detachably mounted on the base 1, and the limiting member 5 is disposed on the second positioning seat 4. The first positioning seat 3 has a plurality of spaced first positioning grooves 34, and the second positioning seat 4 has a plurality of spaced second positioning grooves 43, with each plurality of first positioning grooves 34 corresponding to a plurality of second positioning grooves 43. By providing the detachable first positioning seat 3 and second positioning seat 4, and the one-to-one correspondence between the plurality of first positioning grooves 34 and the plurality of second positioning grooves 43, when cycloidal alignment is required, it is only necessary to remove the first positioning seat 3 and the second positioning seat 4, rotate them 180°, and then reinstall them. The operation is simple and reduces the time required for line position switching. Only one type of first positioning seat and second positioning seat 4 is needed to meet two different wire placement requirements. There is no need to open a separate mold to add a first positioning seat 3 and a second positioning seat 4 for the other wire placement requirement. By using a single specification of first positioning seat 3 and second positioning seat 4 for bidirectional reuse, the mold development cost is reduced by 50%, and the versatility is strong. The clamping seat 2 stably clamps the wire to facilitate subsequent operations. The limiting component 5 limits the rear end of the wire, ensuring that the wire is stably placed in the second positioning groove 43 and that the rear end is flush.

[0037] The first positioning base 3 has a first head 31, a second head 32, and a connecting part 33. The first head 31 and the second head 32 are connected by the connecting part 33. The top of both the first head 31 and the second head 32 has a plurality of first positioning grooves 34, and the plurality of first positioning grooves 34 of the first head 31 correspond one-to-one with the plurality of first positioning grooves 34 of the second head 32. In this embodiment, the first head 31 is located behind the second head 32. When the first head 31 is facing backward, it corresponds to the first type of line position. When the second type of line position is required, the second head 32 is facing backward.

[0038] The top of the connecting part 33 has a wavy surface 35. The wavy surface 35 is provided to increase the friction force on the wire during the next drawing process after the clamping seat 2 has clamped it.

[0039] The first positioning groove 34 includes a first groove 341 and a second groove 342, which are spaced apart. In this embodiment, the first groove 341 is located behind the second groove 342. A drop groove 36 is provided between the first groove 341 and the second groove 342. By providing the drop groove 36, double-sided tape or sprayed glue can be placed in the drop groove 36 to prevent the wire from easily coming out of the first positioning groove 34.

[0040] The first positioning seat 3 has a first locking portion 37, and the clamping seat 2 has a second locking portion 25 that engages with the first locking portion 37. Specifically, the first locking portion 37 of the first positioning seat 3 is a locking block, distributed front and back, and the second locking portion 25 of the clamping seat 2 is a locking groove, distributed front and back. In other embodiments, the first locking portion 37 can be a locking groove, and the second locking portion 25 can be a locking block. The engagement of the first locking portion 37 and the second locking portion 25 enables quick assembly and disassembly of the first positioning seat 3 and the clamping seat 2. When the wire position needs to be changed, the first positioning seat 3 is pulled upward, causing the first locking portion 37 to disengage from the second locking portion 25. Then, the first positioning seat 3 is rotated 180°, so that the first locking portion 37 originally located on the rear side and the first locking portion 37 originally located on the front side are swapped, and respectively engage with the second locking portions 25 on the front and back sides.

[0041] The system includes a first bolt 6, a groove 11 on the top of the base 1, a second positioning seat 4 that slides within the groove 11, a first threaded hole 12 at the bottom of the groove 11, and first mounting holes 41 at both the front and rear ends of the second positioning seat 4. The first bolt 6 passes through the first mounting holes 41 and is screwed into the first threaded holes 12 to mount the second positioning seat 4 onto the base 1. A second positioning groove 43 penetrates the front and rear side walls of the second positioning seat 4. The sliding engagement between the second positioning seat 4 and the groove 11 guides the installation of the second positioning seat 4. In the current state, the first mounting hole 41 at the front end aligns vertically with the first threaded hole 12. To change the alignment, unscrew the first bolt 6, rotate the second positioning seat 4 180° so that the first mounting hole 41, originally located at the rear end, aligns vertically with the first threaded hole 12, and then tighten the first bolt 6. The operation is convenient and quick.

[0042] The limiting component 5 includes a first limiting strip 51 and a second limiting strip 52. The first limiting strip 51 is fixed to the top of the second positioning seat 4 and forms a positioning channel 7 with the second positioning groove 43. The second limiting strip 52 is detachably installed on the top of the second positioning seat 4 and has a stop 53 extending into the second positioning groove 43 at its bottom. The positioning channel 7 limits the rear end of the wire to prevent it from dislodging from the second positioning groove 43. The stop 53 extending into the second positioning groove 43 limits the rear end of the wire to ensure that the insertion length of each wire is consistent.

[0043] The system also includes a second bolt 8, a second positioning seat 4 having several second threaded holes 42 spaced apart, a second limiting strip 52 having a second mounting hole 54, and the second bolt 8 passing through the second mounting hole 54 and screwed into the second threaded hole 42 to install the second limiting strip 52 onto the second positioning seat 4. The position of the second limiting strip 52 can be adjusted in the front-back direction as needed, thereby adjusting the wire insertion length to adapt to different operational requirements.

[0044] The clamping base 2 includes a base 21, a cover plate 22, and a latch 23. The cover plate 22 is positioned above the first positioning groove 34, and its left end is hinged to the left side of the base 21. A soft pad 24 is provided on the bottom wall of the cover plate 22. The latch 23 is located on the right side of the base 21 and is used to lock the cover plate 22 to press and fix the wire in the first positioning groove 34. After the wire is placed in the first positioning groove 34, the cover plate 22 is closed, and then the cover plate 22 is locked by the latch 23. The cover plate 22 stably presses the wire in the first positioning groove 34. The soft pad 24 is provided to prevent damage to the wire.
