Description

Cutter driving mechanism of cable stripping and cutting device

technical field

The utility model relates to a cable stripping and cutting device, in particular to a cutter driving mechanism of the cable stripping and cutting device.

Background technique

In order to realize the standardization of construction in the electric power industry, the stripping and cutting work of the cable armor layer in the construction of the cable head has gradually been replaced by the traditional knife manual stripping and cutting by the cable stripping and cutting device. In the stripping and cutting of the cable, two links of axial stripping and circular stripping are involved, which are respectively completed by their corresponding cutters and cutter driving mechanisms. In the existing cable stripping and cutting device, the driving mechanism of the axial cutter is mainly composed of a guide rail shaft, a guide rail bushing, a vertical rod and an orthogonal clamping spring. The guide rail bushing on the guide rail shaft is connected with the vertical rod, and The vertical rod is connected with the axial cutter assembly through the orthogonal clamping spring to form the entire axial stripping and cutting assembly. When working, the cutter assembly is mainly driven by manpower to move axially along the guide rail axis to complete the task of stripping and cutting cables. This kind of axial cutter drive mechanism is laborious to drive, resulting in high labor intensity for the operator, and it is difficult to ensure the direction and size of the thrust acting on the cutter assembly are consistent, and the connection and cooperation between the parts will inevitably occur. As a result, the transmission stability is poor, the cutting marks are not straight, and the depth is not uniform, which affects the quality of peeling and cutting.

Utility model content

The purpose of the utility model is to provide a cutter driving mechanism of a cable stripping and cutting device. The mechanism has stable transmission, can improve the quality of stripping and cutting, and can reduce the labor intensity of operators.

For this reason, the utility model improves and designs a cutter drive mechanism of a cable stripping and cutting device, including a vertical rod and an orthogonal clamping spring for supporting and connecting the axial cutter assembly, and the lower end of the vertical rod is connected with a nut sleeve, The nut is set on the rectangular threaded screw rod, the side of the nut sleeve is connected with a concave rail plate, and the concave rail plate is matched and connected with a straight rhombus guide rail.

The utility model utilizes the transmission force provided by the screw pair on the rectangular threaded screw rod, guided by the diamond-shaped guide rail, and moves linearly along the cable axis on the workbench of the frame, so as to complete the axial stripping and cutting work. When operating, it is only necessary to apply force to the end of the rectangular threaded screw to make it rotate, and it can be driven by a small force through the turntable or the rotating rod.

The inner hole of the nut sleeve cooperates with the rectangular threaded screw rod through the copper nut to improve the stability of the transmission.

The utility model has the characteristics of stable transmission and labor-saving operation, can improve the quality of cable stripping and cutting, and greatly reduce the labor intensity of operators.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, Figure 2 and Figure 3, the cutter driving mechanism of the cable stripping and cutting device of the present invention includes a vertical rod 2 and an orthogonal clamping spring 3 for supporting and connecting the axial cutter assembly 1, The lower end of vertical bar 2 links to each other with nut cover 4, and nut cover 4 is contained on the rectangular threaded screw mandrel 5, and nut cover 4 sides are connected with concave rail plate 6, and concave rail plate 6 cooperates with a straight rhombus guide rail 7 and links to each other.

The inner hole of the nut sleeve 4 cooperates with the rectangular threaded screw mandrel 5 through a copper nut 8 .

During operation, force is applied to the end of the rectangular threaded screw rod 5 to make it rotate through the turntable or the rotating rod, and the nut sleeve 4 moves linearly on the rectangular threaded screw rod 5, guided by the diamond-shaped guide rail 7, and runs along the working table of the rack. The axis of the cable moves in a straight line, and it can be driven by a small force to complete the axial stripping and cutting work. Because of the stable transmission, the quality of cable stripping and cutting can be improved, and the operation is labor-saving, which greatly reduces the labor intensity of the operator.
