[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic diagram of a preferred embodiment of a wire harness terminal crimping fixture provided by this utility model; Figure 2 for Figure 1 A structural schematic diagram of the cross-sectional view of the fixing frame shown; Figure 3 for Figure 1 The cross-sectional view of the riveting head shown is a structural schematic diagram. Figure 4 for Figure 3 The schematic diagram of the connecting block shows a wire harness terminal riveting fixture, including: a base 1, a replacement component 2 provided on the rear side of the top of the base 1, and a material picking component 3 provided on the left side of the top of the base 1.

[0024] The interchangeable component 2 includes a placement rack 21 located on the top rear side of the base 1. A drive device 22 is provided on the top of the placement rack 21. A connecting block 23 is fixedly provided on the bottom of the drive device 22. A T-shaped slot 24 is provided on the inner side of the connecting block 23. A rivet head 25 is engaged inside the T-shaped slot 24.

[0025] like Figure 4As shown, the T-shaped slot 24 can only allow the riveting head 25 to be inserted from the front. When the riveting head 25 is fully inserted into the T-shaped slot 24, the two fixing rods 27 will extend into the opening at the top of the riveting head 25 under the action of the fixing spring 28. The fixing rods 27 limit the installation of the riveting head 25.

[0026] The material handling assembly 3 includes a fixed frame 31 located on the top left side of the base 1. A limit rod 32 is longitudinally arranged on the inner side of the fixed frame 31. A sliding block 33 is arranged on the periphery of the limit rod 32, which can slide back and forth along its length. An electrically controlled telescopic rod 34 is vertically arranged on the right side of the bottom of the sliding block 33. An electric clamp 35 is arranged at the telescopic end of the bottom of the electrically controlled telescopic rod 34.

[0027] After the wire harness terminals are riveted, the sliding block 33 is slid to a suitable position on the periphery of the limiting rod 32. Then, the electric clamp 35 is lowered to a suitable position by extending the output end of the electric telescopic rod 34. The electric clamp 35 clamps the processed wire harness terminals. At this time, the electric telescopic rod 34 retracts, the sliding block 33 moves forward, and finally the electric clamp 35 releases, allowing the wire harness terminals to fall into the collection box 6.

[0028] A slot 26 is provided on the inner side of the connecting block 23 and above the T-shaped slot 24. Two fixing rods 27 are provided on the inner side of the slot 26 and can slide up and down. The bottom ends of the two fixing rods 27 pass through the inner side of the slot 26 and extend into the interior of the riveting head 25.

[0029] Each of the two fixing rods 27 has a fixing spring 28 at its top end, and the top ends of the two fixing springs 28 are fixed to the inside of the slot 26.

[0030] A rotating rod 29 is rotatably mounted on the inner side of the slot 26. Two ropes are fixedly mounted on the circumferential side of the rotating rod 29. The bottom ends of the two ropes are respectively fixed to the top ends of two fixed rods 27. The right end of the rotating rod 29 passes through the inner side of the slot 26 and extends to the right side of the connecting block 23. A rotating handle 4 is provided on the right end of the rotating rod 29.

[0031] By rotating the handle 4, the rotating rod 29 is rotated, which in turn shortens the rope fixed to the side of the rotating rod 29. The rope then pulls the two fixed rods 27 upward against the force of the fixed spring 28, and finally the bottom of the fixed rod 27 is disengaged from the inside of the riveting head 25. At this point, the riveting head 25 can be removed.

[0032] A rotating screw 36 is longitudinally rotatable and located on the inner side of the fixed frame 31 and above the limiting rod 32. The circumferential side of the rotating screw 36 is threadedly connected to the inner side of the sliding block 33. A drive motor 37 for driving the rotating screw 36 to rotate is provided on the top of the fixed frame 31. The output end of the drive motor 37 is connected to the front end belt of the rotating screw 36.

[0033] The rotation of the output end of the drive motor 37 drives the rotation of the lead screw 36, which in turn, in conjunction with the setting of the limit rod 32, causes the sliding block 33 to move to one side.

[0034] A riveting fixture 5 is provided on the top of the base 1 and below the riveting head 25, and a collection box 6 is provided on the front of the base 1.

[0035] The working principle of the wire harness terminal crimping fixture provided by this utility model is as follows:

[0036] Step 1: When using the device, place the wire harness terminal to be riveted at a suitable position on the top of the riveting fixture 5. The drive device 22 drives the connecting block 23 and the riveting head 25 to move downwards, thereby riveting the wire harness terminal. After processing, the rotation of the output end of the drive motor 37 drives the rotation of the rotating screw 36, which, in conjunction with the setting of the limit rod 32, causes the sliding block 33 to move backwards. When it moves to the wire harness terminal, it stops. The extension of the output end of the electric telescopic rod 34 lowers the electric clamp 35 to a suitable position. The electric clamp 35 clamps the processed wire harness terminal. At this time, the electric telescopic rod 34 retracts, the sliding block 33 moves forwards, and finally the electric clamp 35 releases, allowing the wire harness terminal to fall into the collection box 6 to complete the material retrieval.

[0037] Step 2: When it is necessary to replace the rivet head 25, rotate the handle 4 to rotate the rotating rod 29, which in turn shortens the rope fixed to the side of the rotating rod 29. The rope will then pull the two fixing rods 27 upward against the force of the fixing spring 28, and finally make the bottom of the fixing rods 27 detach from the inside of the rivet head 25. At this time, the rivet head 25 can be removed. Then, the top of the required rivet head 25 is inserted into the T-shaped slot 24. Release the handle 4. Under the action of the fixing spring 28, the two fixing rods 27 slide downward, and their bottom ends pass through the bottom of the slot 26 and finally abut against the inside of the rivet head 25 to fix the rivet head 25. Due to the closed back of the T-shaped slot 24 and the limiting of the two fixing rods 27, the stability of the connection of the rivet head 25 is ensured.

[0038] Compared with related technologies, the wire harness terminal crimping fixture provided by this utility model has the following beneficial effects:

[0039] By inserting the top of the required riveting head 25 into the T-shaped slot 24, the two fixing rods 27 slide downward under the action of the fixing spring 28. Their bottom ends pass through the bottom of the slot 26 and finally abut against the inside of the riveting head 25 to fix the riveting head 25. Due to the closed back of the T-shaped slot 24 and the limiting of the two fixing rods 27, the stability of the riveting head 25 connection is guaranteed. The structure is simple and practical, and the replacement of the riveting head 25 can be completed effectively, quickly and simply. Moreover, the automatic discharge of the riveting device is realized through the material picking component 3, which improves the overall riveting efficiency.
