Description
Technical Field
[0001] The utility model relates to the technical field of motor assembly, in particular to a wire terminal crimping device. Background Art
[0002] When assembling a motor, it is necessary to crimp a wire and a metal head. The main function is to insert the metal head into the insulating layer of the wire and compact it to form a stable connection, so as to realize the on-off of the circuit and signal transmission. In the existing crimping device, the end of the wire is punched several times by a punching part above. During the punching process, due to the poor positioning effect of the punching position, the punching position is likely to shift, resulting in uneven force at the connection position between the wire and the metal head, causing abnormal problems such as insecure terminal crimping or damage to some areas at the end of the wire.
[0003] Therefore, it is necessary to further improve the structure of the wire terminal crimping equipment to improve the crimping accuracy and stability. Summary of the Utility Model

[0018] Figure 2 It is a partial enlarged structural schematic diagram of a wire and cable terminal crimping device of the utility model. Detailed Description of the Preferred Embodiments
[0019] The following further details the specific embodiments of the utility model with reference to the accompanying drawings.
[0020] As Figure 1-2 shown, a wire and cable terminal crimping device of the utility model includes a base 1, a bracket 2, a positioning seat 3, a material placing member 4, a pressing member 5, a lifting rod 6, and a telescopic rod 7;
[0021] The bracket 2 is located on the base 1, the positioning seat 3 is located at the bottom of the bracket 2, and the material placing member 4 is located inside the positioning seat 3; the material placing member 4 is provided with a positioning groove 41, a material placing table 42 extends upward from the middle of the positioning groove 41, and a material placing groove 43 is provided at the top of the material placing table 42; the material placing table 42 is used for placing the end of the wire and cable, and the material placing groove 43 is used for positioning the wire and cable to prevent the wire and cable from shifting during terminal crimping and affecting the crimping effect.
[0022] One end of the material placing table 42 is provided with an inclined surface 44. After the end of the cable is placed on the material placing table 42, the cable is subjected to a downward pressure, and the cable not on the material placing table 42 is slightly bent downward along the inclined surface 44. The inclined surface 44 plays a buffering and protective role on the surface of the cable, preventing the end of the cable from being extruded by the end of the material placing table 42 and causing creases on the cable surface when the end of the cable is subjected to several impacts.
[0023] The positioning seat 3 is provided with a connecting groove 31. The material placing member 4 is detachably fixed in the connecting groove 31 through a first fastener 45. The material placing member 4 with different material placing grooves 43 can be replaced according to the sizes of different cables to adapt to the crimping of cable terminals with different sizes.
[0024] The pressing member 5 is connected to the telescopic rod 7 through a lifting rod 6, and the pressing member 5 is located directly above the material placing member 4; arc-shaped positioning arms 51 are provided at both positions on the bottom of the pressing member 5, and the shape of the positioning groove 41 matches the shape of the arc-shaped positioning arms 51; a clamping groove 52 is provided between the two arc-shaped positioning arms 51, and a pressing rod 521 extends from the middle of the clamping groove 52;
[0025] The telescopic rod 7 controls the lifting of the lifting rod 6 to drive the lifting of the pressing member 5. The telescopic rod 7 can be the telescopic rod of a cylinder or an oil cylinder. A limiting member 21 is provided at the top of the bracket 2, and the limiting member 21 is provided with a sliding groove 22. The lifting rod 6 is connected to the limiting member 21 through the sliding groove 22. The lifting rod 6 always lifts along the sliding groove 22, playing a limiting role in the pressing of the pressing member 5 to prevent the pressing position of the pressing member 5 from shifting.
[0026] When the arc-shaped positioning arms 51 press down, the arc-shaped positioning arms 51 are clamped into the positioning groove 41, thus playing a positioning role in the downward pressing direction of the cable terminal. Compared with a straight rod positioning arm, the positioning effect of the arc-shaped structure of the arc-shaped positioning arms 51 is more stable.
[0027] During the downward pressing process of the pressing member 5, the end of the cable is tightly pressed between the clamping groove 52 and the material placing table 42. The protruding pressing rod 521 increases the pressure of the clamping groove 52 on the cable terminal, further improving the crimping effect.
[0028] The pressing member 5 is detachably fixed to the bottom of the lifting rod 6 through a second fastener 53, facilitating the replacement of the pressing member 5 with different size specifications.
[0029] In this embodiment, the base 1 is provided with a reinforcing rib 11, and one end of the reinforcing rib 11 abuts against the bottom of the bracket 2. When crimping the cable terminal, the pressing member 5 presses the cable from top to bottom along the bracket 2, and the bracket 2 will inevitably vibrate. The reinforcing rib 11 can play a role in stabilizing the bracket 2 and reducing the vibration of the bracket 2.
[0030] A wire terminal crimping device of the present utility model places the end of the wire at an appropriate position of the terminal. Subsequently, the end of the wire is placed on the material placing table 42, and the lifting rod 6 controls the pressing member 5 to press down. The wire and the terminal are tightly pressed between the card slot 52 and the material placing table 42. The pressing member 5 presses and knocks the wire below several times to crimp the wire terminal.
[0031] The preferred embodiments of the present utility model have been specifically described above. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present utility model. These equivalent variations or substitutions are all included within the scope defined by the claims of this application.
