Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing, in particular to a wire harness terminal riveting device. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. As people's requirements for comfort, economy and safety continue to increase, the types of electronic products in cars are also increasing, and automotive wiring harnesses are becoming more and more complex. The wiring harness refers to the contact terminal made of copper material that is crimped with wires and cables, and then plastic-pressed with an insulator or an additional metal shell on the outside to form a component connecting the circuit. When the wiring harness and the terminal are combined, a pressing device is required for pressing.

[0003] There are numerous wire harness running-in devices in the prior art, for example, a Chinese patent with application number CN202320776847.3, authorization publication number CN219535137U, and invention name "A wire harness terminal pressing device". The above patent discloses a wire harness terminal pressing device, including a first base and a second base, a first through groove is opened inside the first base, a cylinder is installed on the top of the first base through a mounting frame, a pressing head is fixed to the output shaft at the bottom of the cylinder by bolts, a second base is arranged on one side of the first base, a second through groove is opened inside the second base, a connecting rod is sleeved on the top of the second base, a rubber block is connected to the top of the connecting rod through a threaded groove, a limiting plate is fixed to the bottom of the connecting rod by bolts, and an upper cutting knife is fixed to the bottom of the limiting plate by bolts.

[0004] In the above patent, the pressure-fitting head is pushed downward by the cylinder to press the terminal head, which has a simple structure and can strip the end of the wire harness so that the terminal head can be covered on the outside of the wire harness. However, it is known that in order to facilitate the installation of the wire harness, the installation station of the wire harness is not located directly below the pressure-fitting station. Therefore, after the installation of the wire harness is completed, the installation station of the wire harness needs to be actively pushed to the bottom of the pressure-fitting station for pressure-fitting operation. The operation process is cumbersome and has certain shortcomings. Utility Model Content

During this stroke, the load-bearing frame is driven to slide horizontally through the linkage member. While the load-bearing frame slides horizontally, the two clamping blocks are driven to approach each other through the trigger member to fix the wiring harness terminal. As the load-bearing plate drives the riveted workpiece to continue to slide downward, the riveting operation can be performed. After the riveting operation is completed, the driving mechanism reverses, driving the load-bearing plate to slide upward, driving the load-bearing frame to reset, and during the load-bearing frame resetting process, the two clamping blocks of the trigger member are unlocked.
