[0022] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Combined with reference Figure 1-Figure 4 The utility model provides a wire harness terminal crimping device, including a machine platform 1 and a hanger 2 arranged on the machine platform 1, a pair of sliding support rods 3 are fixedly connected to the machine platform 1, and a lower die seat 4 and an upper die seat 5 for crimping the wire harness terminals are slidably connected to the pair of sliding support rods 3, the sliding support rods 3 can provide support and guidance for the positions of the lower die seat 4 and the upper die seat 5, the lower die seat 4 is close to the upper surface of the machine platform 1, each sliding support rod 3 is sleeved with a reset spring 6, and the reset spring 6 is located between the lower die seat 4 and the upper die seat 5, The return spring 6 can provide elastic return force for the upper die seat 5. The top end of each sliding strut 3 is threadedly connected with a nut pressure plate 7, which is composed of a nut and a pressure plate. The nut of the nut pressure plate 7 can be threadedly connected with the sliding strut 3, and the pressure plate can be used to limit the upper die seat 5 from falling out at the end of the sliding strut 3. A telescopic device 8 is fixedly connected to the hanger 2. The telescopic device 8 can adopt a telescopic motor. A folding pressure piece 9 is provided at the output end of the telescopic device 8, and the folding pressure piece 9 is movably connected to the upper die seat 5.

[0024] The upper surface of the lower die base 4 is provided with a workpiece groove 41, which is used to place the wiring harness with terminals inserted. The lower surface of the upper die base 5 is fixedly connected with a pressing head 51 for crimping the terminals on the wiring harness. By inserting the terminal into one end of the wiring harness and then placing it into the workpiece groove 41, the upper die base 5 can be close to the lower die base 4 to crimp the terminal at one end of the wiring harness. In the present application, the number of workpiece grooves 41 and pressing heads 51 is the same and multiple are provided, so that multiple wiring harness terminals can be crimped at the same time.

[0025] Both ends of the reset spring 6 are fixedly connected with spring seats 61, and the spring seats 61 are slidably connected to the sliding support rod 3. The spring seats 61 can reduce the wear of the two ends of the reset spring 6 and the upper die seat 5 and the lower die seat 4. The opposite surfaces of the upper die seat 5 and the lower die seat 4 are provided with receiving grooves for placing the spring seats 61. The setting of the receiving grooves utilizes the receiving groove positions provided by the upper die seat 5 and the lower die seat 4 to provide an extension range for the reset spring 6. When the reset spring 6 is in the maximum compression state, the downward position of the pressure head 51 can effectively act on the terminal of the workpiece groove 41.

[0026] The upper die base 5 and the lower die base 4 are both embedded with linear bearings 10 slidably connected to the sliding support rod 3 . The provision of the linear bearings 10 can increase the smoothness of the upper die base 5 and the lower die base 4 on the sliding support rod 3 .

[0027] An auxiliary slide bar 11 is fixedly connected to the machine table 1, and the upper mold base 5 and the lower mold base 4 are both slidably connected to the auxiliary slide bar 11. The auxiliary slide bar 11 can further increase the smoothness of the upper mold base 5 and the lower mold base 4, especially provide a balancing effect for the upper mold base 5 that needs to be lifted or lowered.

[0028] A damping square pad 12 is arranged at the bottom of the lower die base 4, and the damping square pad 12 is movably inserted into the auxiliary sliding rod 11 and the sliding support rod 3. The damping square pad 12 can provide buffering protection for the lower die base 4 when the upper die base 5 applies pressure on the lower die base 4.

[0029] A damping ring pad 13 is fixedly connected to the bottom of the nut pressure plate 7. The damping ring pad 13 is movably inserted into the sliding support rod 3 and abuts against the upper surface of the upper die seat 5. The damping ring pad 13 is arranged so that when the reset spring 6 is compressed and reset, the damping ring pad 13 can buffer the rebound of the upper die seat 5 to suppress the jumping of the reset spring 6, thereby stabilizing the crimping stability of the upper die seat 5.

[0030] The folding pressure member 9 includes a rotating frame 91 fixedly connected to the output end of the telescopic device 8 and a pressing plate 92 connected to the inner side of the rotating frame 91 in a damping rotation manner. One end of the pressing plate 92 movably abuts against the upper surface of the upper mold base 5 .

[0031] Specifically, when it is necessary to crimp a wiring harness with terminals, the pressure plate 92 is in an upright state, and the extension of the piston of the telescopic device 8 can control the pressure plate 92 to press down on the upper die seat 5. At this time, the upper die seat 5 can move up and down on the sliding support rod 3, and the reset spring 6 is in a compressed state until the pressure head 51 acts on the terminal at one end of the wiring harness to complete the crimping; when the telescopic device 8 drives the pressure plate 92 to rise, the reset spring 6 elastically resets, so that the upper die seat 5 can reset the crimping position; when it is necessary to disassemble the upper die seat 5 and the lower die seat 4, the connection of the nut pressure plate 7 on the sliding support rod 3 can be released, and the pressure plate 92 can be folded on the rotating frame 91, which can provide an effective removal channel between the hanger 2 and the sliding support rod 3, so that the upper die seat 5 and the lower die seat 4 on the sliding support rod 3 can be quickly slid out, and disassembly and assembly are more convenient.
