Detailed Implementation
[0027] The following is in conjunction with the appendix Figures 1 to 7 This utility model will be described in detail.
[0028] This utility model is a multi-station adjustable stroke terminal crimping machine, including a base 1. A stamping device 2 is installed on the base 1. The stamping device 2 includes a stamping motor 21, a slider 22, and a stamping head 23. The stamping motor 21 is driven and connected to the slider 22, and the stamping head 23 is connected to the slider 22. The stamping motor 21 drives the stamping head 23 to move up and down along the base 1 to stamp the terminal through the slider 22. An adjusting device 3 for adjusting the stamping stroke of the stamping head 23 is also installed on the base 1. Here, the stamping stroke refers to the longest distance between the stamping head 23 and the terminal during a single stamping process, that is, the height of the stamping head 23 from the terminal when it is in the highest stamping position. In this technical solution, the adjusting device 3 includes an adjusting motor 31 and a drive shaft 32 driven and connected to the adjusting motor 31. The drive shaft 32 is telescopically connected to the stamping head 23 and can drive the stamping head 23 to rotate. The stamping head 23 is threadedly connected to the slider 22. The operating principle of the adjustment device 3 is as follows: When the adjustment motor 31 is started, the drive shaft 32 rotates and drives the punch head 23 to rotate. Since the punch head 23 and the slider 22 are connected by a thread, the punch head 23 will generate a lifting displacement inside the slider 22 while rotating, thereby achieving the purpose of adjusting the punching stroke of the punch head 23. Moreover, this adjustment process will not interfere with the punching process of the terminal machine, and can achieve the technical effect of independent punching and adjustment.
[0029] The terminal crimping machine of this invention can automatically adjust the stamping stroke of the stamping head 23 through ingenious structural design without affecting the stamping process. This makes the terminal crimping machine no longer limited to stamping a single type of terminal. It can adjust the stamping stroke at any time according to the specifications of the stamped terminal, significantly expanding the application range of the terminal crimping machine, which is more conducive to production and simplifies the terminal stamping process.
[0030] This technical solution also includes an eccentric roller 4, through which the stamping motor 21 is connected to the slider 22. Figure 2 As shown, when the motor's power is transmitted to the slider 22 through the eccentric roller 4, it can drive the slider 22 to have a higher punching force during the lifting process, thereby ensuring that the terminal block machine can stably form each punch and improve the stamping yield.
[0031] As one embodiment, the eccentric roller 4 includes a roller body 41 and an eccentric wheel 42 disposed at the front end of the roller body 41. The roller body 41 is connected to the stamping motor 21, and the eccentric wheel 42 is connected to the slider 22.
[0032] Preferably, a transverse groove 221 is provided on one side of the slider 22. The transverse groove 221 accommodates the eccentric wheel 42 and is slidably connected to the eccentric wheel 42. When the stamping motor 21 drives the eccentric wheel 42 to rotate circumferentially, the transverse groove 221 can provide sufficient space for the eccentric wheel 42 to move, so that the adjusting motor 31 can stably drive the slider 22 to move up and down along the machine base 1 to complete the stamping process.
[0033] In another embodiment, the outer end of the eccentric wheel 42 is movably sleeved with a movable block 421, which is slidably connected to the transverse slide groove 221. The addition of the movable block 421 makes the connection between the eccentric wheel 42 and the slider 22 more stable and the movement process more stable.
[0034] Preferably, the base 1 is also provided with a longitudinal slide groove 11, and the slider 22 is slidably connected to the longitudinal slide groove 11. The longitudinal slide groove 11 limits the slider 22, preventing the slider 22 from deviating during its vertical movement and causing stamping errors.
[0035] In this technical solution, a connecting post 231 is fixedly provided on the top of the stamping head 23; the drive shaft 32 is hollow and is sleeved on the outside of the connecting post 231. In order to stably install the stamping head 23 in the slider 22, the outer wall of the stamping head 23 is provided with an external thread for connecting with the slider 22, and the slider 22 is similarly provided with an internal thread for matching.
[0036] To ensure that the drive shaft 32 can rotate the stamping head 23 without affecting the stamping action, a limiting part 321 is provided on the inner wall of the drive shaft 32, and a flat part 232 adapted to the limiting part 321 is provided on the outer wall of the connecting column 231. When the drive shaft 32 is sleeved on the outside of the connecting column 231, the limiting part 321 just abuts against the flat part 232, and the drive shaft 32 laterally locks the connecting column 231, preventing the connecting column 231 from rotating inside the drive shaft 32 but allowing it to extend and retract. This is the key reason why the stamping process and the adjustment process can be carried out simultaneously.
[0037] Preferably, the drive shaft 32 extends into the interior of the slider 22, and the drive shaft 32 is movably connected to the slider 22 so that even if the drive shaft 32 drives the stamping head 23 to rotate, it will not affect the movement of the slider 22. At the same time, this structural arrangement can further compact the terminal machine structure and shorten the overall volume of the terminal machine.
[0038] like Figure 1 As shown, the base 1 is also equipped with a rotary feeding device 5; the rotary feeding device 5 is located below the stamping device 2, and the rotary feeding device 5 includes a turntable 51 and a rotary motor 52 for driving the turntable 51 to rotate. The turntable 51 is circumferentially provided with multiple stamping stations 53.
[0039] In one embodiment, the stamping station 53 includes a fixed base 531, a movable base 532, and a stamping plate 533 connected in sequence. The fixed base 531 is movably fitted with the movable base 532. The fixed base 531 is provided with a stamping platform 534. In use, the terminal to be stamped is placed on the stamping platform 534. When the stamping head 23 moves downward and abuts against the movable base 532, it pushes the movable base 532 to slide along the fixed base 531. The stamping plate 533, mounted on the movable base 532, moves downward to press the terminal into shape. This invention can realize the automatic adjustment of the stamping stroke, so that even if terminals of different specifications are placed in the stamping station 53, the terminal machine can continuously stamp and form them, which is more conducive to production.
[0040] Preferably, a separator block 233 is movably sleeved on the outside of the stamping head 23, and a pressure sensor 234 is mounted on the separator block 233. The separator block 233 separates the stamping head 23 from the pressure sensor 234, so that the pressure sensor 234 is not affected when the stamping head 23 is rotated to adjust its position. Here, the pressure sensor 234 is mainly used to detect the stamping force and observe whether the single stamping force meets the standard.
[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
