[0020] The present utility model provides a rear - type wire clamping mechanism for a stripping and terminal - crimping machine, including a protection component 101, a positioning wire - clamping component 102, a limiting component 103, a movable wire - clamping component 104, and a telescopic component 105.

[0021] For this specific embodiment, the telescopic component 105 is fixedly connected to the protection component 101, the limiting component 103 is fixedly connected to the protection component 101, the positioning wire clamping component 102 is fixedly connected to the protection component 101, the mounting shaft 109 is fixedly connected to the protection component 101, the movable block 108 is rotatably connected to the mounting shaft 109, the rotating shaft 107 is fixedly connected to the movable block 108, one end of the electric telescopic rod 106 is rotatably connected to the rotating shaft 107, the other end of the electric telescopic rod 106 is fixedly connected to the protection component 101, the protection block 111 is fixedly connected to the protection shell 110, the protection shell 110 is fixedly connected to the telescopic component 105, each anti-slip strip 113 is fixedly connected to the positioning block 112, the positioning block 112 is fixedly connected to the protection shell 110, the limiting pad 115 is fixedly connected to the limiting plate 114, the limiting plate 114 is fixedly connected to the protection shell 110, the built-in plate 118 is fixedly connected to the protection block 111, one end of the air rod 117 is fixedly connected to the built-in plate 118, the other end of the air rod 117 is fixedly connected to the output end of the air cylinder 116. The currently provided electric telescopic rod 106 controls the rotation of the movable block 108, changing the clamping of the copper wire from squeezing clamping to changing the twisting posture of the copper wire, increasing the friction, and maintaining a stable clamping effect on the copper wire while reducing damage. This design solves the problems of easy damage to the wire head during the clamping process of the copper wire, affecting the production progress, and being unable to ensure the integrity of the copper wire after clamping.

[0022] Among them, the telescopic component 105 is located on one side of the protection component 101, the limiting component 103 is located on the inner wall of the protection component 101, the positioning wire clamping component 102 is located on the inner wall of the protection component 101, the mounting shaft 109 is located inside the protection component 101, the movable block 108 is located on the periphery of the mounting shaft 109, the rotating shaft 107 is located on one side of the movable block 108, one end of the electric telescopic rod 106 is located on the periphery of the rotating shaft 107, the other end of the electric telescopic rod 106 is located on the inner wall of the protection component 101. The movable block 108 has a through hole for the copper wire to pass through. The copper wire enters the interior of the protection shell 110 from the outer through hole of the movable block 108. At this time, the electric telescopic rod 106 retracts in length, the movable block 108 rotates and gradually presses against the positioning block 112. During the movement of the movable block 108, the copper wire also gradually presses against the side of the positioning block 112 with the anti-slip strip 113.

[0023] Secondly, the protective block 111 is located on one side of the protective shell 110. The protective shell 110 is located at one end of the telescopic assembly 105. Each anti-slip strip 113 is located on one side of the positioning block 112. The positioning block 112 is located on the inner wall of the protective shell 110. The protective shell 110 is connected to the cylinder 116 and the air rod 117 through the protective block 111 to control and move the protective shell 110. The arrangement of multiple anti-slip strips 113 ensures the friction on the rubber outer skin around the copper wire and prevents the outer skin of the copper wire from detaching from the clamping of the positioning block 112 and the movable block 108.

[0024] Meanwhile, the limiting pad 115 is located on one side of the limiting plate 114. The limiting plate 114 is located on the inner wall of the protective shell 110. The built-in plate 118 is located inside the protective block 111. One end of the air rod 117 is located on one side of the built-in plate 118. The limiting pad 115 is a soft rubber pad and is fixed to the inner wall of the protective shell 110 through the limiting plate 114. It is arranged on the path that the copper wire must pass through to limit the movement of the copper wire and prevent the copper wire from continuously entering the interior of the protective shell 110, which affects the clamping effect. The cylinder 116 is installed on one side of the peeling and end-forming machine to provide an installation condition for the cylinder 116. The cylinder 116 drives the air rod 117, thereby driving the movement of the built-in plate 118 and the protective shell 110. It moves to the position of the copper wire to be clamped and realizes the entry or exit of the copper wire from the interior of the protective shell 110 through telescopic movement.

[0025] In this embodiment, the movable block 108 has a through hole for the copper wire to pass through. The copper wire enters the interior of the protective shell 110 from the outer through hole of the movable block 108. At this time, the electric telescopic rod 106 retracts in length, and the movable block 108 rotates and gradually presses against the positioning block 112. During the movement of the movable block 108, the copper wire also gradually presses against the side of the positioning block 112 with the anti-slip strip 113. In addition, the movable block 108 changes the position of the through hole, and the copper wire is in a bent posture, improving the clamping and stabilizing effect on the copper wire, increasing the clamping efficiency without damaging the copper wire. The protective shell 110 is connected to the cylinder 116 and the air rod 117 through the protective block 111 to realize the control and movement of the protective shell 110. The arrangement of multiple anti-slip strips 113 ensures the friction on the rubber outer skin of the copper wire around the circumference, preventing the outer skin of the copper wire from detaching from the clamping of the positioning block 112 and the movable block 108. The limit pad 115 is a soft rubber pad, fixed to the inner wall of the protective shell 110 through the limit plate 114, arranged on the path that the copper wire must pass through, to limit the movement of the copper wire and prevent the copper wire from continuously entering the interior of the protective shell 110, affecting the clamping effect. The cylinder 116 is installed on one side of the peeling and end-forming machine, providing an installation condition for the cylinder 116. The cylinder 116 drives the air rod 117, thereby driving the movement of the built-in plate 118 and the protective shell 110, moving to the position of the copper wire to be clamped, and realizing the entry or exit of the copper wire from the interior of the protective shell 110 through telescopic movement.
