Description

Technical Field:

[0001] The utility model relates to the technical field of wire stripping, and particularly refers to a rear-stage wire stripping device. Background Art:

[0002] A terminal wire includes a wire and a terminal fixed to the end of the wire. Before assembly, a wire stripping mechanism is required to strip the end face of the wire to expose the metal wire core, and then a terminal pressing machine is used to press and fix the terminal onto the metal wire core of the wire to complete the production of the terminal wire.

[0003] The Chinese patent application for invention with publication number CN118367487A discloses a wiring cable end stripping device, which includes: a base; a lower cutting member slidably disposed on the base in the front-back direction, the lower cutting member includes a first lower skin cutting knife, a lower cutting knife, and a second lower skin cutting knife sequentially arranged at intervals in the front-back direction; an upper cutting member disposed above the lower cutting member, slidably connected to the lower cutting member and slidable in the vertical direction, the upper cutting member includes a first upper skin cutting knife, an upper cutting knife, and a second upper skin cutting knife sequentially arranged at intervals in the front-back direction, a pressure receiving block is provided at the upper part of the upper cutting member, and the pressure receiving block is provided with an inclined sliding surface; a lower pressing block, the bottom of which is slidably connected to the sliding surface; a constraint sleeve fixedly disposed and sleeved at the connection of the lower pressing block and the pressure receiving block; and a driving mechanism connected to the lower pressing block to drive the lower pressing block to move downward. First, the lower pressing block and the pressure receiving block move downward in the constraint sleeve, the upper cutting knife and the lower cutting knife cut the cable to generate two ends, the first upper skin cutting knife and the first lower skin cutting knife cut the outer skin of one of the ends located in the front, and the second upper skin cutting knife and the second lower skin cutting knife cut the outer skin of one of the ends located in the rear; then the pressure receiving block leaves the constraint sleeve and slides relative to the lower pressing block, driving the upper cutting member and the lower cutting member to move forward to remove the outer skin of one of the ends located in the rear.

[0004] Although the above-mentioned wiring cable end peeling device can realize the peeling of the cable to remove the cable outer skin, there are some deficiencies in the above-mentioned wiring cable end peeling device: The above-mentioned wiring cable end peeling device uses a driving mechanism to drive the pressing block and the pressure-receiving block to move downward in the restraint sleeve, so that the first and second skin-cutting knives move towards the first and second lower skin-cutting knives respectively to approach the first and second lower skin-cutting knives, thereby realizing the skin-cutting action. However, in this process, the first and second lower skin-cutting knives do not move, only the first and second skin-cutting knives move downward, which results in a large movement stroke of the first and second skin-cutting knives and affects the skin-cutting quality. In addition, the driving mechanism is a cylinder, and its operating accuracy is not high. It cannot accurately control the stroke accuracy of the first and second skin-cutting knives moving downward, and there is a risk that the first and second skin-cutting knives move downward excessively and collide with the first and second lower skin-cutting knives, causing damage.

The driving mechanism 8 includes a first swing block 81 and a second swing block 82 rotatably mounted in the tool rest 2 and a first link module 83 for driving the second swing block 82 to swing. One end of the first swing block 81 is rotatably connected to the first end 821 of the second swing block 82. The other end of the first swing block 81 is movably connected to the upper tool holder 4. The second end 822 of the second swing block 82 is rotatably connected to the first link module 83. The third end 823 of the second swing block 82 is movably connected to the lower tool holder 4. When the first link module 83 pulls the second swing block 82 to swing, the second swing block 82 drives the first swing block 81 to swing synchronously to drive the upper tool holder 4 and the lower tool holder 5 to move closer or open relative to each other. When the present utility model is working specifically, after the wire is sent between the upper cutting knife 6 and the lower cutting knife 7, the driving mechanism 8 drives the upper tool holder 4 and the lower tool holder 5 to move closer relative to each other, and then drives the upper cutting knife 6 and the lower cutting knife 7 to move closer relative to each other to cut the outer skin of the wire. At the same time, the horizontal driving module 3 drives the tool rest to move horizontally, so that the upper cutting knife 6 and the lower cutting knife 7 after moving closer move horizontally, and then peel the outer skin relative to the wire to achieve the peeling effect. Among them, when the driving mechanism 8 is working, the first link module 83 pulls the second swing block 82 to swing. When the second swing block 82 swings, it will pull the first swing block 81 to swing synchronously, so as to drive the first swing block 81 and the second swing block 82 to move in opposite directions, so as to be able to drive the upper tool holder 4 and the lower tool holder 5 to move closer or open relative to each other. Its movement is stable, ensuring that the upper cutting knife 6 and the lower cutting knife 7 can perform stable relative closing or opening actions, making the strokes of the upper cutting knife 6 and the lower cutting knife 7 the same, and thus being able to ensure the peeling quality. Moreover, the driving mechanism 8 adopts the assembly structure of the first link module 83, the first swing block 81 and the second swing block 82, its movement is stable, and it can drive the upper cutting knife 6 and the lower cutting knife 7 to perform precise relative closing movement, that is, it can control the stroke accuracy of the downward movement of the upper cutting knife 6 and the lower cutting knife 7, avoiding the phenomenon of damage caused by their collision.

Among them, when the driving mechanism 8 is working, the first link module 83 pulls the second swing block 82 to swing. While the second swing block 82 swings, it will pull the first swing block 81 to swing synchronously, and then drive the first swing block 81 and the second swing block 82 to move in opposite directions, so as to be able to drive the upper tool seat 4 and the lower tool seat 5 to approach each other or open relative to each other.
