Description

Technical Field

[0001] This utility model relates to a cable insulation stripping device, specifically a high-precision cable stripping device. Background Art

[0002] With the continuous development of society, high-voltage cables are increasingly widely used due to their advantages such as urban aesthetics, small footprint, and high power supply reliability, which in turn increases the number of high-voltage cable accessories. The development of urban power grid construction has led to a higher cable usage rate and a rapid increase in the amount of cable accessory installation work. During the installation process, the stripping speed of the cable insulation layer greatly affects the progress of the installation project.

[0003] During cable accessory installation, a cable insulation stripper is an indispensable tool. A high-voltage cable insulation stripper typically includes a blade body, blades, and an adjustment mechanism. The blades are usually made of high-strength, highly wear-resistant materials to ensure they remain sharp and are not easily damaged when stripping insulation. The cutting depth of the blade can be controlled via the adjustment mechanism (such as an adjustment handle or blade adjustment knob) to accommodate insulation layers of different thicknesses and materials.

[0004] However, existing cable insulation stripping knives have the following shortcomings:

[0005] 1. The peeling knife cannot accurately control the cutting depth of the blade during the peeling process, resulting in the blade cutting too deep or too shallow when peeling the insulation layer.

[0006] 2. The tool holder is prone to shaking, resulting in uneven peeling depth of the insulation layer.

[0007] 3. Poor blade material selection affects the peeling effect and the durability of the blade.

[0008] 4. Bending of the cable may cause the cable stripper to become eccentric during operation. Utility Model Content

[0009] The purpose of this invention is to overcome the above-mentioned problems and provide a high-precision cable stripping device. This high-precision cable stripping device can accurately control the cutting depth of the blade during the stripping process and has good stability, which is beneficial to improving the stripping accuracy.

[0010] The objective of this utility model is achieved through the following technical solution:

[0011] A high-precision cable stripping device includes a stripping frame and stripping rollers, stripping blades, a blade holder, and a stripping adjustment mechanism mounted on the stripping frame.

[0012] The peeling adjustment mechanism includes an adjusting bolt, an adjusting slider, and an adjusting guide rail. One end of the adjusting bolt is a rotating part, and the other end of the adjusting bolt is rotatably connected to the tool holder. The adjusting slider is connected to the adjusting bolt via a threaded structure and can slide through the adjusting guide rail. One end of the adjusting guide rail is fixedly connected to the tool holder. The tool holder is mounted on the peeling frame.

[0013] The handle of the peeling knife is fixedly connected to the adjusting slider, and the handle of the peeling knife is provided with a scale.

[0014] The working principle of the above-mentioned high-precision cable stripping device is as follows:

[0015] During operation, the cable is placed on the stripping roller. By rotating the corresponding adjusting bolt, the stripping blade is driven closer to the cable, thereby removing the cable's insulation layer. The operator can adjust the blade position according to the scale on the blade handle to ensure stripping accuracy; the scale also serves as a reference during the stripping process, helping the operator monitor the stripping progress. Furthermore, when the adjusting bolt is rotated, the adjusting slider slides on the adjusting guide rail, preventing the blade from shifting and improving feed accuracy.

[0016] In a preferred embodiment of this utility model, the peeling frame includes a fixed plate and a movable plate, wherein two fixed plates are provided and are fixedly connected by a mounting rod;

[0017] The tool holder is mounted on one of the fixed plates;

[0018] The movable plate is slidably mounted on the mounting rod and is located between two fixed plates;

[0019] The peeling rollers are provided in two sets and arranged opposite to each other. One set of peeling rollers is rotatably connected to one of the fixed plates, and the other set of peeling rollers is rotatably connected to the movable plate.

[0020] An adaptive compression spring is fitted onto the mounting rod, and the adaptive compression spring is located between the movable plate and another fixed plate.

[0021] With the above structure, the cable stripper can be adaptively adjusted by a spring to hold the cable tightly, depending on the specifications or model of the cable or the bending of the cable. The spring is selected with a wire diameter of 2mm, an outer diameter of 20mm, and a length of 150mm.

[0022] Furthermore, the movable plate is provided with a first locking screw. In the locked state, the end of the first locking screw passes through the movable plate and rests against the mounting rod.

[0023] In a preferred embodiment of this invention, the blade holder is provided with a second locking screw. In the locked state, the end of the second locking screw passes through the blade holder and rests against the handle of the peeling blade. With this structure, the peeling blade can be locked by the second locking screw, maintaining the current peeling depth, preventing loosening, and ensuring peeling quality.

[0024] In a preferred embodiment of this invention, the adjusting slider is provided with a third locking screw. In the locked state, the end of the third locking screw passes through the adjusting slider and rests against the handle of the peeling blade. With this structure, when the peeling blade needs to be replaced, the third locking screw can be loosened, allowing the peeling blade to be removed and replaced.

[0025] In a preferred embodiment of this utility model, the peeling knife is made of high-quality alloy material or 316L to ensure that the blade is sharp and durable, and can maintain stable cutting performance during peeling.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1. By setting a scale, the position of the blade can be adjusted according to the changes in the scale on the handle of the peeling blade, thus ensuring peeling accuracy.

[0028] 2. When the adjusting bolt is rotated, the adjusting slider can slide on the adjusting guide rail. The adjusting guide rail provides precise guidance, and the cutting tool will not deviate, thus improving the feed accuracy.

[0029] 3. For cables of different specifications or in cases of cable bending, the cable stripper can use a spring to adaptively grip the cable and perform its work. Attached Figure Description
