Detailed ways

What should be explained at first is that in the context of the present invention, terms related to orientation such as "left end", "right end", "above" and "below" are used, and these terms are all based on the insulation layer peeled off of the cable sample. The direction of the front view of the equipment is used as the reference, while "axial" and "radial" are based on the axial and radial directions of the cable sample. In addition, each component is described as it is installed on the cable sample insulation stripping equipment, so the viewing directions of "left view", "right view" and "top view" are the same as those of the cable sample Corresponding view directions for insulation stripping equipment.

The following will describe in detail the preferred embodiments of an electric tension type cable sample clamping mechanism and corresponding cable sample insulating layer stripping equipment of the present invention with reference to FIGS. 1-19 .

In order to facilitate the description of the structure and function of the electric tensioning type cable sample clamping mechanism of the present invention, the preferred structure of the cable sample insulation layer stripping device of the present invention is briefly described with reference to Figs. 1-3. The cable sample insulation layer stripping equipment of the present invention mainly includes: a base 01, a longitudinal feed device 02, a first clamping device 03, a second clamping device 03', a radial cutting device 04, an axial cutting device 05, and Tensioning device 06. Wherein, the first clamping device 03 and the second clamping device 03' are used to clamp both ends of the cable sample; the tensioning device 06 is used to 1. One of the second clamping devices 03, 03' exerts a force to make the clamped cable sample tight, and correspondingly, one of the first and second clamping devices 03, 03' It is fixedly installed on the tensioning device 06, thereby constituting the electric tensioning type cable sample clamping mechanism of the present invention; the axial cutting device 05 is used to cut the The insulating layer of the cable sample is cut at least a part; the radial cutting device 04 is used to cut the insulating layer of the cable sample in the radial direction; the longitudinal feeding device 02 is used to drive along the axial direction of the cable sample The axial cutting device 05 and the radial cutting device 04 move relative to the base 01 .

Preferably, the main structures of the first clamping device 03 and the second clamping device 03' are the same. Wherein, one of the two (for example, the first clamping device 03 ) can be fixedly installed on the base 01 , for example, installed on the left end of the base 01 , and the other (for example, the second clamping device 03 ′) is movably installed on the base 01, for example, the tensioning device 06 is installed on the right end of the base 01, so that the tensioning device 06 can apply force to the second clamping device 03', so that the second clamping device 03' faces away from the first The direction of the clamping device 03 is moved so that the clamped cable sample is tightened.

After understanding the basic functions of the cable sample insulation stripping device of the present invention, the structure of the electric tensioning type cable sample clamping mechanism of the present invention will be described in detail next. However, it should be understood that the application occasions of the cable sample clamping mechanism of the present invention are not limited to the cable sample insulation layer stripping device of the present invention, but can be applied to any suitable occasion, as long as there is clamping of the cable sample. Tight and taut as needed.

Preferably, as shown in Figures 4-9, the electric tensioning cable sample clamping mechanism of the present invention includes a clamping device (such as the first clamping device 03 or the second clamping device 03') and a tensioning Device 06. Wherein, the clamping device 03 or 03' includes a pair of clamping arms 31A and a clamping drive mechanism, each free end of the clamping arm 31A is provided with a clamping V-shaped block 31B, and two clamping V-shaped blocks 31B are provided.

As shown in FIGS. 10-11 , the axial cutting device 05 preferably includes a limiting mechanism 62 and a cutting mechanism 63 . The cutting mechanism 63 is used to cut into the insulation layer of the cable sample in the radial direction, and moves in the axial direction under the action of the feeding motion of the corresponding longitudinal feeding device 02 to cut the insulation layer. The limit mechanism 62 is used to provide the cable sample with a Radial support to prevent deformation or displacement of cable samples.

When the cutting mechanism 63 is fed towards the cable sample, the tip of the axial cutting blade 56 can penetrate the insulation layer. After this, when the cutting mechanism 63 is fed along the axial direction of the cable sample, The cutting edge and tip of the axial cutting blade 56 will cut the insulating layer to a certain length.

Alternatively, the limiting mechanism 62 and the cutting mechanism 63 can also be fed independently in the radial direction. For example, after the cable sample is clamped, the limiting mechanism 62 is first driven to feed in the radial direction so that the cable sample is clamped. support, and then drive the cutting mechanism 63 to advance radially so as to cut into the insulating layer.

Preferably, as shown in FIG. 11 , the left and right screw nut mechanism 64 includes a second left and right screw screw 61 and a pair of axial screw nuts 60 with opposite rotation directions, and the axial screw nuts 60 are respectively connected to the The left-handed thread part of the second left-handed screw 61 cooperates with the right-handed thread part. The limiting mechanism 62 and the cutting mechanism 63 are respectively fixed to one of the axial screw nuts 60 .
