[0029] like Figures 1 to 3As shown, this embodiment provides a wire crimping device for a tubular terminal, comprising a wire crimping body and a driving member 2, wherein the wire crimping body comprises a fixed panel 11, a pin shaft 12, a crimping tooth 13, a gear ring 14 and a connecting rod 15, the fixed panel 11 is placed flat on a workbench, a plurality of pin shafts 12 are provided, and a plurality of pin shafts 12 are distributed on the fixed panel 11 at intervals along the circumferential direction, and the crimping tooth 13 is rotatably connected to the pin shaft 12, so that the crimping tooth 13 can only rotate around the rotating shaft, limiting the movement of the crimping tooth 13. A plurality of crimping teeth 13 are provided, and a plurality of crimping teeth 13 are assembled one by one with a plurality of rotating shafts, and a crimping surface 131 is provided at one end of the crimping tooth 13 to crimp the tubular terminal, and after the corresponding assembly of the crimping teeth 13 and the pin shaft 12 is completed, a plurality of crimping surfaces 131 will be mutually enclosed, and finally a crimping port 16 will be formed, and when crimping is performed, the staff will put the cable with the tubular terminal into the crimping port 16 to crimp the tubular terminal. The gear ring 14 is located on the fixed panel 11, and the rotating shaft and the pressing gear 13 are both placed in the center hole of the gear ring 14. The other end of the pressing gear 13 is connected to the inner wall of the gear ring 14. At this time, the pressing gear 13 forms a linkage with the gear ring 14. The connecting rod 15 is connected to the gear ring 14. When the connecting rod 15 is pushed, the gear ring 14 will be thrusted and then drive the pressing gear 13 to rotate around the pin 12. Since the pressing gear 13 and the gear ring 14 are in linkage, the pressing gear 13 will drive the gear ring 14 to rotate when it rotates. At this time, multiple crimping surfaces 131 are close to each other, and the crimping interface 16 becomes smaller, so as to realize the crimping of the tube type terminal. The driving member 2 is connected to the connecting rod 15 and can drive the connecting rod 15 to move. Therefore, when the staff energizes the driving member 2, it can drive the connecting rod 15 to move, thereby bringing multiple crimping surfaces 131 close to each other, crimping the tube type terminal, avoiding manual crimping of the terminal, and saving a lot of manpower. At the same time, the driving force of the driving member 2 is stable, so that the thrust given by the connecting rod 15 to the gear ring 14 is stable. Each time the cable with the tubular terminal is crimped, the contraction degree of the crimping port 16 is consistent, thereby ensuring the consistent crimping degree of the tubular terminal on each cable and ensuring the product quality of the cable.

[0031] In this embodiment, the driving member 2 includes a cylinder 21 and a control switch. The control switch is used to control the start and stop of the cylinder 21. The driving rod of the cylinder 21 is connected to the connecting rod 15. When the staff turns on the control switch, the driving rod extends to drive the connecting rod 15 to move. At this time, the pressing teeth 13 rotate around the pin shaft 12, and the crimping interface 16 contracts to crimp the tubular terminal onto the cable.

[0032] In this embodiment, Figure 1 and Figure 2 As shown in the figure, the wire crimping body also includes a front panel 17, the front panel 17 faces the fixed panel 11 and the pin shaft 12 is connected between the fixed panel 11 and the front panel 17, that is, the gear ring 14 and the pressing tooth 13 are located between the fixed panel 11 and the front panel 17, and the setting of the front panel 17 can prevent the gear ring 14 from falling off, so that the staff can place the wire crimping body vertically on the workbench. At the same time, an opening 171 is also provided on the front panel 17, and the opening 171 is arranged opposite to the crimping port 16, so that it is convenient for the staff to put the cable with the tubular terminal into the crimping port 16, thereby improving the convenience of the staff's operation. In order to further improve the stability of the connection between the fixed panel 11 and the front panel 17, the wire pressing body also includes a locking piece 19 for locking the fixed panel 11 and the front panel 17. By way of example, the locking piece 19 includes a bolt and a nut. A plurality of first mounting holes are provided on the fixed panel 11, and a plurality of second mounting holes are provided on the front panel 17. After passing through the first mounting holes and the second mounting holes, the bolts are threadedly connected with the nuts to lock the fixed panel 11 and the front panel 17.

[0033] In this embodiment, the wire crimping body also includes a base plate 18, on which a first positioning groove and a second positioning groove are arranged. The first positioning groove and the second positioning groove are parallel to each other and spaced apart, wherein the fixed panel 11 is clamped in the first positioning groove, and the front panel 17 is clamped in the second positioning groove, so that the staff can quickly and accurately assemble the wire crimping body. At the same time, the setting of the base plate 18 can make the wire crimping body more stably placed on the workbench.

[0034] Preferably, the wire crimping body further comprises a plurality of rollers, which are placed at intervals below the bottom plate 18 so that the staff can move the tube-type terminal wire crimping device, wherein the rollers have a self-locking function so that the staff can lock the rollers at a predetermined position to ensure that the tube-type terminal wire crimping device can be stably placed. It is worth noting that the rollers with a self-locking function are widely used in the field of household appliances and are conventional technical means, and are not the key protection content of the present utility model.

[0035] Preferably, the connecting rod 15 and the gear ring 14 are an integrated structure, which can not only improve the stability of the connection between the connecting rod 15 and the gear ring 14 and ensure the stability of the wire pressing body structure, but also facilitate the processing of the connecting rod 15 and the gear ring 14, saving the processing steps of the wire pressing body.

[0036] In this embodiment, the tubular crimping terminal also includes a top plate 3, which is opposite to the bottom plate 18 and connected to the fixed panel 11, that is, the top plate 3 is placed above the fixed panel 11, and the driving member 2 is placed on the top plate 3, so that the driving member 2 and the crimping body are more compact, making the tubular crimping terminal device miniaturized.
