Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] See Figures 1-3In this embodiment of the present invention, a multi-core wire harness welding fixture includes a base 1, a fixed cylinder 3 fixedly connected to the base 1, a rotating insert rod 4 slidably installed inside the fixed cylinder 3, a mounting platform 7 fixedly connected to the rotating insert rod 4, two sets of symmetrically arranged first fixed shafts 8 fixedly connected to each side of the mounting platform 7, two sets of equidistantly parallel rotating arms 9 rotatably connected to each of the two sets of first fixed shafts 8, a second fixed shaft 14 rotatably connected to the rotating arm 9, a clamping platform 13 fixedly connected to the second fixed shaft 14, a fixed clamping groove 15 fixedly connected to one side of the clamping platform 13, a telescopic clamping groove 19 provided on one side of the fixed clamping groove 15, a push block 10 fixedly connected to the end of the rotating arm 9 away from the second fixed shaft 14, a positioning rod 11 fixedly connected to the push block 10, and a spring 12 installed between the positioning rods 11; a positioning clamping assembly is installed inside the fixed cylinder 3; and a pushing assembly is installed inside the clamping platform 13.

[0019] This invention first controls the two sets of clamping platforms 13 to unfold, and then controls the telescopic clamping groove 19 to move away from the fixed clamping groove 15 through the push assembly, thereby opening the telescopic clamping groove 19 and the fixed clamping groove 15. Then, the two sets of wire harnesses are placed between the fixed clamping groove 15 and the telescopic clamping groove 19, and then the telescopic clamping groove 19 and the fixed clamping groove 15 are closed through the push assembly. The wire harnesses are then clamped and fixed through the telescopic clamping groove 19 and the fixed clamping groove 15. Then, the two sets of clamping platforms 13 are released. At this time, the spring 12 pushes the two sets of push blocks 10 to unfold synchronously. The push blocks 10 drive the rotating arm 9 to rotate around the first fixed shaft 8. The rotating arm 9 drives the two sets of clamping platforms 13 to rotate and close through the second fixed shaft 14. The clamping platforms 13 drive the two sets of wire harnesses to close synchronously, thereby allowing the two sets of multi-core wire harnesses to be inserted into each other in an interlaced manner. At this time, the multi-core wire harnesses can be soldered.

[0020] Furthermore, this utility model can adjust the height and relative angle of the two sets of wire harnesses through the sliding connection between the fixed cylinder 3 and the rotating insertion rod 4. After the adjustment is completed, the fixed cylinder 3 and the rotating insertion rod 4 are clamped and fixed relative to each other through the positioning clamping assembly.

[0021] In one instance of this embodiment, please refer to Figures 1-3 The base 1 is fixedly connected to an anti-slip pad 2. This utility model uses the anti-slip pad 2 to prevent the base 1 from slipping.

[0022] In one instance of this embodiment, please refer to Figures 1-3The positioning and clamping assembly includes a threaded hole 5 fixedly connected in the fixed cylinder 3, and a fixing bolt 6 is threadedly connected in the threaded hole 5. The fixing bolt 6 cooperates with the rotating insert rod 4. The positioning and clamping assembly controls the fixing bolt 6 to rotate and extend in the threaded hole 5 through the threaded connection between the threaded hole 5 and the fixing bolt 6, thereby pushing and clamping the rotating insert rod 4 through the fixing bolt 6.

[0023] In one instance of this embodiment, please refer to Figures 1-3 The pushing assembly includes a threaded cylinder 16 fixedly connected to the clamping table 13, a screw 17 internally threadedly connected to the threaded cylinder 16, the screw 17 being rotatably connected to the telescopic clamping groove 19 via a rotating connector 18, and a knob 20 fixedly connected to the driving end of the screw 17.

[0024] The push assembly drives the screw 17 to rotate by turning the knob 20. The screw 17 is connected to the threaded cylinder 16 by a thread, which converts the rotational motion of the screw 17 into the linear motion of the screw 17, thereby driving the screw 17 to rotate and extend. The screw 17 drives the telescopic clamping groove 19 to extend and retract relative to each other by rotating the connector 18. The wire is clamped and fixed by the mutual cooperation between the telescopic clamping groove 19 and the fixed clamping groove 15.

[0025] The working principle of this utility model is as follows: First, the two sets of clamping platforms 13 are unfolded. Then, the screw 17 is rotated by turning the knob 20. The screw 17 is connected to the threaded cylinder 16 by a thread, which converts the rotational motion of the screw 17 into linear motion, thereby causing the screw 17 to rotate and extend. The screw 17 drives the telescopic clamping groove 19 to extend and retract relative to each other by rotating the connector 18. The telescopic clamping groove 19 is controlled to move away from the fixed clamping groove 15, thereby opening the telescopic clamping groove 19 from the fixed clamping groove 15. Then, the two sets of wire harnesses are placed in the fixed clamping groove. Between the slot 15 and the telescopic clamping slot 19, the telescopic clamping slot 19 and the fixed clamping slot 15 are controlled to close by the push assembly, thereby clamping and fixing the wire harness through the telescopic clamping slot 19 and the fixed clamping slot 15. Then, the two sets of clamping platforms 13 are released. At this time, the spring 12 pushes the two sets of push blocks 10 to unfold synchronously. The push blocks 10 drive the rotating arm 9 to rotate around the first fixed shaft 8. The rotating arm 9 drives the two sets of clamping platforms 13 to rotate and close through the second fixed shaft 14. The clamping platforms 13 drive the two sets of wire harnesses to close synchronously, thereby allowing the two sets of multi-core wire harnesses to be inserted into each other in an alternating manner. At this time, the multi-core wire harnesses can be soldered.

[0026] Furthermore, this utility model can adjust the height and relative angle of the two sets of wire harnesses through the sliding connection between the fixed cylinder 3 and the rotating insertion rod 4. After the adjustment is completed, the fixed bolt 6 is controlled to rotate and extend in the threaded hole 5, and then the rotating insertion rod 4 is pushed and clamped by the fixed bolt 6, thereby clamping and fixing the fixed cylinder 3 and the rotating insertion rod 4 relative to each other.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
