[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 2 An embodiment of the utility model provides a terminal crimping device for automobile wiring harness, comprising: a frame 1 and a support plate 2.

[0020] Among them, Figure 1-Figure 3 As shown, a support plate 2 is installed on the top of the frame 1, a downward pressure cylinder 3 is installed on the front surface of the support plate 2, the piston rod of the downward pressure cylinder 3 is fixedly connected to the insertion rod 8, a shell 5 is installed on the top of the frame 1, a turntable 6 is installed on the top of the shell 5 through a rotating shaft, a plurality of terminal crimping jigs 7 are installed on the top of the turntable 6 in a circumferential distribution, and the number of terminal crimping jigs 7 is not less than five, a linear groove 12 is provided on the top of the terminal crimping jig 7, an L-shaped slider 18 is slidably installed inside the linear groove 12, and a terminal mounting seat 11 is installed on the top of the L-shaped slider 18.

[0021] Furthermore, a driving motor 9 is installed inside the shell 5, and the rotating shaft of the driving motor 9 is fixedly connected to the bottom of the turntable 6. When in use, the automobile wiring harness is inserted into the terminal and installed on the terminal mounting seat 11 on the top of the terminal crimping jig 7. By starting the downward pressure cylinder 3, the insertion rod 8 is driven to descend and the terminal on the terminal mounting seat 11 is pressed, thereby completing the crimping operation of the automobile wiring harness terminal, and the driving motor 9 can drive the turntable 6 to rotate, thereby changing the position of multiple terminal crimping jigs 7 on the top of the turntable 6, which is convenient for crimping operations on other wiring harness terminals.

[0022] like Figure 1 and Figure 2 As shown, a shield 4 is fixedly connected to the front surface of the support plate 2, and the insertion rod 8 is located inside the shield 4. The shield 4 can cover and protect the insertion rod 8 and reduce the operator's hands and limbs from accidentally touching the insertion rod 8.

[0023] In this embodiment, Figure 1-Figure 4 As shown, a threaded hole 15 is provided inside the terminal crimping jig 7, and an external threaded rod 16 is connected to the internal thread of the threaded hole 15. A keyway 17 is provided at one end of the external threaded rod 16, and the other end is rotatably connected to one side of an L-shaped slider 18 through a bearing. An adjusting rod 13 is provided inside the threaded hole 15.

[0024] The operator can insert the adjusting rod 13 into the threaded hole 15 of the terminal crimping jig 7, and rotate it in the docking key slot 17, driving the external threaded rod 16 to move back and forth in the threaded hole 15, and at the same time drive the L-shaped slider 18 and the terminal mounting seat 11 to move along the linear groove 12, so that when the automobile wiring harness terminal is crimped, the terminal mounting seat 11 on the terminal crimping jig 7 can be finely adjusted in distance, so that the terminal and the crimping end correspond to each other up and down.
