the utility model provides a cutting mechanism of wire stripping instrument, includes the mechanism seat, and the fixed cable locating sleeve that is used for supplying corresponding cable to wear to adorn that is provided with on the mechanism seat, and the direction removes to be equipped with two and can move relatively and move in opposite directions on the mechanism seat and move the cutter body, and two move the cutter body and distribute in the both sides of cable locating sleeve, two opposite sides that move the cutter body are provided with the sinle silk and dodge the groove, and the axis of cable locating sleeve is in the sinle silk dodges on the extending direction of groove heart motion trail.
The mechanism seat comprises two guide rods which are arranged in parallel, each movable cutter body is assembled on the two guide rods in a guiding and moving way, and the cable positioning sleeve is fixed at the middle parts of the two guide rods.
The cable positioning sleeve comprises a fixed valve and a movable valve, one end of the movable valve is hinged with the fixed valve, the fixed valve is fixed in the middle of the two guide rods, and the other end of the movable valve is connected with the fixed valve through a detachable connecting structure.
The detachable connection structure is a bolt detachable connection structure.
A first arc-shaped stop part which is used for being matched with the outer circumferential surface of the movable valve in an adaptive stop way when the two movable cutter bodies are close to each other is arranged on one movable cutter body; the other movable cutter body is provided with a left arc-shaped stop part and a right arc-shaped stop part which are used for being matched with the outer peripheral surface of the fixed valve in an adaptive stop way when the two movable cutter bodies are mutually close.
The beneficial effects of the invention are as follows: according to the invention, the cable positioning sleeve is fixed on the mechanism seat, the two movable cutters relatively move to finish stripping of the steel strands at the outer side of the cable, and the axis of the cable positioning sleeve is positioned in the extending direction of the movement track of the core avoidance groove center, so that the cable core is ensured to be positioned at the center position of the core avoidance groove, the movable cutters are placed to damage the cable core in a staggered manner, and the cable positioning sleeve and the mechanism seat are fixed, so that the problem of abrasion is avoided, and the long-time high-precision use of the cutting mechanism is ensured.

Fig. 1 is a schematic structural view of an embodiment of the present invention.
Detailed Description
An embodiment of a cutting mechanism of a wire stripping tool is shown in fig. 1: the cable positioning sleeve comprises a fixed flap 5 and a movable flap 4 with one end connected with the fixed flap in a hinged mode, the other end of the movable flap 4 is detachably connected with the fixed flap through a bolt detachable connection structure, two ends of the fixed flap 5 are fixedly connected with the two guide rods respectively, and two ends of the fixed plate are welded and fixed with the two guide rods in the embodiment. Two movable cutter bodies are arranged on the guide rod in a guiding and sliding manner at two sides of the cable positioning sleeve, the two movable cutter bodies are respectively called a first movable cutter body 1 and a second movable cutter body 7, and a first arc-shaped stop part 9 which is used for being matched with the outer peripheral surface of the movable valve in a stop fit manner when the two movable cutter bodies are close to each other is arranged on one movable cutter body; the other movable cutter body is provided with a left and a right arc-shaped stop parts 10 which are used for being matched with the outer peripheral surface of the fixed valve in an adaptive stop way when the two movable cutter bodies are close to each other. The opposite sides of the two movable cutter bodies are provided with wire core avoiding grooves 2, the wire core avoiding grooves are arc grooves in the embodiment, the axis of the cable positioning sleeve is perpendicular to the moving direction of the two movable cutter bodies, and the axis of the cable positioning sleeve is positioned in the extending direction of the wire core avoiding groove core moving track.
When the wire stripping tool is used, the cutting mechanism is matched with the movable cutter body driving mechanism, the movable cutter body driving mechanism can be an air cylinder, a hydraulic cylinder or an electric push rod, and the like, and the movable cutter body driving mechanism moves relatively and oppositely with two movable cutters, and the cutting mechanism and the movable cutter body driving mechanism form the wire stripping tool together. The cable to be stripped passes through the cable positioning sleeve, the outer diameter of the cable is matched with the inner diameter of the cable positioning sleeve, and because the axis of the cable positioning sleeve is perpendicular to the moving directions of the two movable cutter bodies, the cable is also perpendicular to the moving directions of the two movable cutter bodies, so that the flatness and the verticality of a cutting surface and the axis of the cable are ensured, the two movable cutter bodies relatively move to cut the aluminum stranded wire at the outer side of the cable until the first arc-shaped stopping part and the second arc-shaped stopping part respectively prop against the outer circumferential surfaces of the two sides of the cable positioning sleeve, and at the moment, the cutting is completed, and the matching structure ensures that the two movable cutter bodies can not touch the cutter, and simultaneously ensures that the two movable cutter bodies can not cut the wire core in a transitional way. The cable positioning sleeve and the mechanism seat are fixedly connected, so that the vertical relation between the movable cutter body and the cable is easily ensured, the problem of abrasion caused by movement of the cable positioning sleeve is avoided, and the long-time high-precision use of the product can be ensured. In the figure, item 8 represents a wire core, and item 6 represents an aluminum stranded wire at the periphery of the wire core.
In other embodiments of the invention: the cable positioning sleeve can also be of an integrated structure; the bolt detachable connection structure can also be replaced by a buckle detachable connection structure; the motion track of the two moving cutter bodies can also be arc-shaped, for example, the two moving cutter bodies move like scissors around a certain circle center in an arc shape.
