Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, wherein it is noted that the references to positions or positional relationships in the description of the invention are based on the references to positions or positional relationships illustrated in the drawings and are provided for the purpose of facilitating the description of the invention and simplifying the description, and do not refer to or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular manner and therefore should not be considered as limiting the invention.

As shown in fig. 1 to 12, the present invention provides a chuck type cable stripping device, which includes a three-jaw chuck 1 and three sets of pinch roller cutters 2, wherein each set of pinch roller cutters 2 is connected to one jaw 101. A pinch roller support 3 is arranged between the pinch roller cutter 2 and the clamping jaw 101, the pinch roller cutter 2 is rotatably connected with the pinch roller support 3, and the pinch roller support 3 is connected with the clamping jaw 101 through a bolt. Every two groups of the pressure wheel cutters 2 are arranged at an included angle of 120 degrees. The pinch roller knife 2 is composed of a pinch roller shaft 201, a blade 202, a fixed pinch roller 203 and a limiting pinch roller 204, the fixed pinch roller 203 and the pinch roller shaft 201 are of an integral structure, and the limiting pinch roller 204 is in threaded connection with the pinch roller shaft 201. The blade 202 is sleeved on the pinch roller shaft 201 and is positioned between the fixed pinch roller 203 and the limiting pinch roller 204. Therefore, the limiting pressing wheel 204 is in threaded connection with the pressing wheel shaft 201, the blade 202 can be pressed on the fixed pressing wheel 203, and the blade 202 is prevented from loosening in the process of peeling the cable 6. In order to facilitate the positioning of the cable center, the pressing wheel surfaces 205 of the fixed pressing wheels 203 and the limiting pressing wheels 204 are provided with concave cambered surfaces so as to increase the contact area with the surface of the cable 6.

When the device is used, the device is placed between two traction devices, a cable 6 to be stripped passes through a space formed between the three groups of pressure wheel cutters 2, and the position of the jaw 101 on the chuck is adjusted, so that the thickness of the three groups of pressure wheel cutters 2 for stripping the insulating layer is proper. The pulling device is then activated, causing the cable 6 to move forward with the movement of the pulling device. The traction speed can also be adjusted to ensure that the cable 6 has good effect of stripping the insulating layer. Because the three groups of pinch cutters 2 move through the claws 101, the invention can be applied to cables 6 with various outer diameter sizes. Three sets of pinch roller sword 2 can be fixed 6 centers of cable, and then prevents that cable 6 from shifting at the removal in-process, and the insulating layer that leads to peels off not in place at the cable 6 center, need not to increase the stop device who is used for fixed cable 6 centers.

Further, the pinch roller support 3 comprises a pinch roller base 301 and a pinch roller support base 302, and the pinch roller support base 302 is connected with the pinch roller base 301 through bolts. The pinch roller supporting seat 302 is provided with a stepped hole, and a bearing 4 is in transition fit in the stepped hole. The pinch roller supporting seat 302 has two and is located the both sides of pinch roller sword 2, and the both ends of pinch roller axle 201 are transition fit with bearing 4 respectively. The bearing 4 can reduce the friction force when the cable 6 is stripped.

Further, the pressing wheel base 301 includes a connecting block 3011 and a fixing plate 3012 which are integrally formed. The connecting block 3011 is a stepped structure adapted to the claw 101 so as to be tightly attached to the claw 101, thereby ensuring the working stability after adjustment and positioning. The plane of the fixing plate 3012 is perpendicular to the moving direction of the jaws 101.

Furthermore, the outer side of the top end of the pinch roller supporting seat 302 is provided with a 60-degree chamfer, so that the pinch roller cutter 2 can be attached closer to the center when moving to be suitable for the cable 6 with smaller outer diameter.

Further, the three-jaw chuck 1 is fixedly connected with the wire stripper support 5 so as to be convenient to move. A reinforcing rib plate 501 is welded on the wire stripping machine bracket 5.

The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
