[0006] To achieve the above objectives, this utility model provides the following technical solution: a terminal riveting device, comprising a base, a bottom mold disposed above the base and connected to the base by screws, a groove disposed at the upper end of the bottom mold, a stand disposed above the base and fixedly connected to the base, an mounting plate disposed inside the stand, a hydraulic cylinder disposed above the mounting plate and connected to the stand by screws, the telescopic end of the hydraulic cylinder connected to the mounting plate, a top mold disposed below the mounting plate and connected to the mounting plate by screws, the top mold disposed above the bottom mold, two clamping blocks disposed above the bottom mold, the two clamping blocks disposed on both sides of the groove, a first electric push rod disposed on one side of each of the two clamping blocks, the first electric push rod connected to the stand by screws, the telescopic end of the first electric push rod connected to the clamping block, and an electrical control box disposed at the front end of the base and connected to the base by screws.

[0007] Preferably, the top of the support frame is provided with a first through hole, and there are four first through holes. Each of the four first through holes is provided with a first guide rod, and the first guide rod is slidably connected to the support frame. The lower ends of the four first guide rods are fixedly connected to the four corners of the mounting plate.

[0008] Preferably, the mounting plate includes an upper plate, a lower plate, and a pressure detection module. The lower plate is disposed below the upper plate, and the pressure detection module is disposed between the upper plate and the lower plate. The upper and lower ends of the pressure detection module are fixedly connected to the upper plate and the lower plate, respectively.

[0009] Preferably, an L-shaped connecting bracket is provided on one side of the mounting plate, and the L-shaped connecting bracket is connected to the mounting plate by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model device, through the setting of a groove, a first electric push rod and a clamping block, allows the end to be placed into the groove for pre-positioning. The first electric push rod drives the clamping block to move and contact the end, clamping and fixing it from both sides of the end to prevent the end from shifting during the extrusion process and improve the terminal riveting effect.

[0015] This utility model device, through the setting of the mounting plate, which is composed of a multi-layer structure, includes a pressure detection module when the top mold and the end contact instantaneously. The pressure detection module can not only play a buffer protection role, but also measure the magnitude of the extrusion force on the end, so as to avoid excessive force damage to the end and improve the quality of terminal riveting.

[0016] This utility model device uses a rubber block and a spring. The rubber block rises and falls synchronously with the mounting plate. When the rubber block falls, it first contacts the wire harness and clamps and positions the wire harness. The spring automatically contracts after being subjected to force, which will not cause the wire harness to be excessively clamped and subjected to force. This ensures that the wire harness is compressed under force during the terminal riveting process, which will prevent the wire harness from being incompletely riveted to the end and improve the terminal riveting effect.

[0017] This utility model device uses a second electric push rod, a lifting plate, and a top rod. The second electric push rod drives the lifting plate to rise and fall. As the lifting plate rises and falls, it drives the top rod to rise and fall. When the top rod rises, it applies an upward thrust to the end in the groove, which makes it easier to push the end out and remove the riveted terminal. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-5 This utility model provides an embodiment of a terminal riveting device, comprising a base 1, a bottom mold 4 disposed above the base 1 and connected to the base 1 by screws, a groove 11 disposed at the upper end of the bottom mold 4, a stand 5 disposed above the base 1 and fixedly connected to the base 1, a mounting plate 7 disposed inside the stand 5, a hydraulic cylinder 6 disposed above the mounting plate 7 and connected to the stand 5 by screws, the telescopic end of the hydraulic cylinder 6 being connected to the mounting plate 7, and a... There is a top mold 15, which is connected to the mounting plate 7 by screws. The top mold 15 is set above the bottom mold 4. There are two clamping blocks 17 on the top of the bottom mold 4. The two clamping blocks 17 are set on both sides of the groove 11. A first electric push rod 12 is set on one side of each of the two clamping blocks 17. The first electric push rod 12 is connected to the upright frame 5 by screws. The telescopic end of the first electric push rod 12 is connected to the clamping block 17. An electric control box 3 is set at the front end of the base 1. The electric control box 3 is connected to the base 1 by screws.

[0026] In use: Place the end into the groove 11, insert the wire harness into the end, and arrange the wire harness into the groove 11. Drive the first electric push rod 12 to move the clamping block 17 to contact the end and clamp and fix it from both sides of the end. Drive the hydraulic cylinder 6 to drive the mounting plate 7 to descend. As the mounting plate 7 descends, the top mold 15 falls to contact the end. The top mold 15, together with the bottom mold 4, applies extrusion pressure to the end, and the terminal is riveted by means of extrusion pressure.

[0027] Please see Figure 1 and Figure 3The top of the support frame 5 is provided with four first through holes 8. Each of the four first through holes 8 is provided with a first guide rod 9, and the first guide rod 9 is slidably connected to the support frame 5. The lower ends of the four first guide rods 9 are fixedly connected to the four corners of the mounting plate 7. The mounting plate 7 includes an upper plate 20, a lower plate 21, and a pressure detection module 22. The lower plate 21 is located below the upper plate 20, and the pressure detection module 22 is located between the upper plate 20 and the lower plate 21. The upper and lower ends of the pressure detection module 22 are fixedly connected to the upper plate 20 and the lower plate 21, respectively. The mounting plate 7 is composed of a multi-layer structure. When the top mold 15 comes into instantaneous contact with the end, it squeezes the pressure detection module 22. With the help of the pressure detection module 22, it can not only play a buffer protection role, but also measure the magnitude of the squeezing force on the end, avoid excessive force damage to the end, and improve the quality of terminal riveting.

[0028] Please see Figure 1 , Figure 2 and Figure 5 An L-shaped connecting bracket 10 is provided on one side of the mounting plate 7, and the L-shaped connecting bracket 10 is connected to the mounting plate 7 by screws. A rubber block 18 is provided below the L-shaped connecting bracket 10. A spring 19 is provided above each end of the rubber block 18, and the two ends of the spring 19 are fixedly connected to the L-shaped connecting bracket 10 and the rubber block 18, respectively. The L-shaped connecting bracket 10 has two second through holes 13. A second guide rod 14 is provided inside each of the two second through holes 13, and the second guide rod 14 is slidably connected to the L-shaped connecting bracket 10 and the spring 19. The lower end of the second guide rod 14 is connected to the rubber block 18. The rubber block 18 rises and falls synchronously with the mounting plate 7. When the rubber block 18 falls, it first contacts the wire harness and clamps and positions the wire harness. The spring 19 will automatically retract after being subjected to force, which will not cause the wire harness to be excessively clamped and stressed. This ensures that the wire harness is stressed and retracted during the terminal riveting process, which will prevent the wire harness from being incompletely riveted to the end, thus improving the terminal riveting effect.

[0029] Please see Figure 1 and Figure 4The upper end of the base 1 is provided with an installation cavity 23, which is located below the bottom mold 4. A lifting plate 24 is provided inside the installation cavity 23 and is slidably connected to the base 1. A second electric push rod 16 is provided below the lifting plate 24 and is connected to the base 1 by screws. The telescopic end of the second electric push rod 16 is connected to the lifting plate 24. Two push rods 25 are provided at the bottom of the groove 11 and are slidably connected to the bottom mold 4. The lower end of the top rod 25 is fixedly connected to the lifting plate 24. A support seat 2 is provided below the base 1. There are four support seats 2, and the support seats 2 are connected to the base 1 by screws. The four support seats 2 are located at the four corners of the base 1. The second electric push rod 16 drives the lifting plate 24 to rise and fall. As the lifting plate 24 rises and falls, it drives the top rod 25 to rise and fall. When the top rod 25 rises, the top rod 25 applies an upward pushing force to the end in the groove 11, which makes it easier to push the end out and remove the riveted terminal.

[0030] Working principle: The terminal is placed into the groove 11, and the wire harness is inserted into the terminal. The wire harness is then arranged and placed into the groove 11. The first electric push rod 12 is driven to move the clamping block 17 to contact the terminal and clamp it from both sides. The hydraulic cylinder 6 is driven to lower the mounting plate 7. The rubber block 18 rises and falls synchronously with the mounting plate 7. When the rubber block 18 falls, it first contacts the wire harness and clamps and positions it. As the mounting plate 7 falls, the top mold 15 falls and contacts the terminal. The top mold 15, together with the bottom mold 4, applies pressure to the terminal. The terminal is riveted by means of the pressure. After riveting is completed, the second electric push rod 16 is driven to raise and lower the lifting plate 24. As the lifting plate 24 rises and falls, the top rod 25 rises and falls. When the top rod 25 rises, it applies an upward pushing force to the terminal in the groove 11, which facilitates the removal of the terminal and makes it easier to remove the riveted terminal.
