Description

Technical Field

[0001] This utility model relates to the field of connector housing processing tools, and in particular to a multi-station fixture for connector housing processing. Background Technology

[0002] Connector housings protect the electronic components of the connector. They are typically made of metal and enclose the electronic components. The production of connector housings involves multiple processing steps. In the production workshop, defective connector housings need to be reworked. When reworking connector housings, their small size makes it inconvenient for operators to hold them by hand. While using clamps such as vises, only one housing can be clamped at a time, further hindering operation and resulting in low rework efficiency.

[0003] Therefore, the lack of dedicated fixtures in the existing connector housing technology leads to low repair efficiency. Utility Model Content

[0004] This utility model provides a multi-station fixture for connector housing processing, which solves the technical problem of low rework efficiency of connector housings due to the lack of dedicated fixtures during rework.

[0005] Some implementation schemes for solving the above-mentioned technical problems include:

[0006] A multi-station fixture for machining connector housings includes a base;

[0007] A clamping cylinder is rotatably connected to the base. The inner sidewall of the clamping cylinder is provided with a clamping groove, which is evenly distributed along the circumference of the clamping cylinder.

[0008] A clamping block is slidably connected to the clamping cylinder along the diameter direction of the clamping cylinder. The clamping block cooperates with the clamping groove to clamp the connector housing. Each clamping block corresponds to an independent clamping groove.

[0009] and a drive assembly that drives all the clamping blocks to simultaneously move closer to or further away from the clamping slot;

[0010] The drive assembly includes a stud rotatably connected to the clamping cylinder, the stud being disposed on the clamping cylinder by a connecting bracket that prevents the stud from displacing axially along the clamping cylinder;

[0011] The drive assembly also includes a nut disposed on and cooperating with the stud, and a connecting rod is disposed between the nut and the clamping block. One end of the connecting rod is rotatably connected to the clamping block, and the other end of the connecting rod is rotatably connected to the nut. Each connecting rod corresponds to an independent clamping block.

[0012] A guide mechanism is provided between the clamping block and the clamping cylinder.

[0013] Preferably, the base is provided with a shaft, the shaft and the base are integrally formed, and the lower end of the clamping cylinder is provided with a connecting plate, the connecting plate being provided with a shaft hole that mates with the shaft.

[0014] Preferably, the connecting plate and the clamping cylinder are an integral structure, and a rolling bearing is provided between the shaft hole and the shaft body. The inner ring of the rolling bearing is interference-fitted with the shaft body, and the outer ring of the rolling bearing is interference-fitted with the shaft hole.

[0017] Preferably, the upper frame is fixed to the connecting plate by a screw, the lower frame is fixed to the connecting plate by a screw, and the upper end of the stud is provided with an operating part that facilitates rotating the stud.

[0018] Preferably, the guiding mechanism includes a guide rail disposed on the clamping block, the guide rail having a cross-sectional shape that is narrower at the top and wider at the bottom trapezoid, and the inner wall of the clamping cylinder having a sliding groove that mates with the guide rail.

[0019] Preferably, the guide rail and the clamping block are an integral structure, and each clamping block is provided with at least two guide rails.

[0020] Preferably, the inner wall of the clamping cylinder is provided with a protruding ring, the protruding ring protruding from the inner wall of the clamping cylinder toward the center of the clamping cylinder, the protruding ring and the clamping cylinder are integrally formed, and the sliding groove is provided on the protruding ring.

[0021] Preferably, the upper end of the connecting rod is rotatably connected to the clamping block via a first rotating shaft, and the lower end of the connecting rod is rotatably connected to the nut via a second rotating shaft.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] Multiple clamping slots are evenly arranged circumferentially along the upper edge of the clamping cylinder, each corresponding to an independent clamping block. Multiple connector housings can be clamped simultaneously in a single operation, significantly improving rework efficiency. The studs and nuts in the drive assembly, through the transmission of the connecting rod, allow all clamping blocks to simultaneously move closer to or further away from the clamping slots. This design not only simplifies operation but also ensures that each connector housing is clamped evenly and stably.

[0024] The guide mechanism between the clamping block and the clamping cylinder ensures the stability and accuracy of the clamping block during sliding. When clamping the connector housing, it prevents insecure clamping or damage to the housing due to clamping block misalignment.

[0025] The entire clamp has a compact structure, which not only saves space but also makes operation more convenient. Operators can easily control the clamping and releasing of all the clamps by simply turning the studs, greatly improving work efficiency.

[0026] The clamping sleeve is rotatably connected to the base. The clamping sleeve can rotate relative to the base, which can easily rotate the connector housing to a suitable position, facilitating rework operations. Attached Figure Description
