[0021] Referring to the attached Figure 1 , an adjustable elastic cutter head wire harness insulation layer removal tool is provided in an embodiment of the present application, including a lower clamp body and an upper clamp body 1. The lower clamp body is provided with a transverse cutting groove 201 and an annular cutting groove 202. The upper clamp body 1 and the lower clamp body are connected to form a self-closing clamp structure. The upper clamp body 1 is respectively provided with movable and adjustable stripping tools corresponding to the transverse cutting groove 201 and the annular cutting groove 202. The stripping tool is provided with a tool adjusting member for adjusting the distance between the stripping tool and the corresponding cutting groove. The tool adjusting member is provided with an adaptive telescopic member 5 for pressing down the stripping tool to complete wire stripping.

[0022] As is well known, a cable is composed of a wire core, a wire harness shielding layer, and a wire harness insulation layer. The wire harness shielding layer wraps the wire core. The wire harness shielding is used to reduce or eliminate the influence of external electromagnetic interference (EMI) on the internal transmission signal, and at the same time can also prevent the electromagnetic generated by the internal signal from spreading outward. The wire harness insulation layer is a material structure with a certain thickness and continuous coverage that wraps around the wire harness shielding layer. The insulation layer closely adheres to the surface of the wire and can maintain its insulation performance under normal use conditions (including bending, stretching, temperature changes, etc.), so as to ensure the safe and reliable transmission of electrical energy or signals by the wire harness.

[0023] In the prior art, after the insulation layer stripping rotary knife clamps the wire harness, it rotates to complete the cutting of the insulation layer. Since the knife post is fixed, it is suitable for single-core wires with regular shapes and not suitable for wire harnesses of different specifications. When the wire harness changes, it is necessary to replace the corresponding wire number stripper or manually adjust the feed amount of the blade 302, and the cutting stroke of the knife edge is fixed, so it cannot be applied to wire harnesses with irregular shapes (such as twisted wire harnesses). When stripping the insulation layer of a wire harness with a thinner insulation layer, it is easy to damage the internal wire core or shielding layer, and moreover, the downward pressure of the knife edge of the traditional stripper is not fixed, and the cutting depth is not fixed.

[0024] Therefore, in this embodiment, by providing a wire stripping tool with an adjustable position on the upper clamp body 1 and using a tool adjusting member to adjust the distance between the wire stripping tool and the tangent slot, it is possible to be applicable to wire harnesses of different models for stripping the insulating layer. At the same time, by using the adaptive telescopic member 5, the downward pressure of the wire stripping tool can be adjusted to avoid damaging the internal wire core or shielding layer.

[0025] In one embodiment, as Figure 1 and Figure 2 shown, the upper clamp body 1 and the lower clamp body are made by resin 3D printing. The upper clamp body 1 and the lower clamp body are integrally formed with connecting ear plates for mutual connection in the middle. The connecting ear plates are provided with coaxial connecting holes, and a pivot shaft is inserted into the connecting holes. A torsion spring connected to the upper clamp body 1 and the lower clamp body is arranged on the pivot shaft.

[0026] In the above embodiment, the upper clamp body 1 and the lower clamp body are connected by the pivot shaft, so that the upper clamp body 1 and the lower clamp body can rotate around the pivot shaft. And by arranging a torsion spring connected to the upper clamp body 1 and the lower clamp body on the pivot shaft, the upper clamp body 1 and the lower clamp body are kept in a closed state by the elastic force to clamp the cable during the wire stripping process.

[0027] In one embodiment, as Figure 1 and Figure 2 shown, the upper clamp head is provided with a bottom plate 101, a partition plate 102 and a top plate 103 from bottom to top. The bottom plate 101 is provided with a bottom plate through hole 104, the partition plate 102 is provided with a partition plate through hole 105, and the top plate 103 is provided with a top plate through hole 106. The bottom plate through hole 104 and the partition plate through hole 105 are used for slidingly installing the wire stripping tool, and the top plate through hole 106 is used for slidingly installing the tool adjusting member.

[0028] In the above embodiment, by providing the bottom plate 101, the partition plate 102 and the top plate 103 on the upper clamp head, and correspondingly providing the bottom plate through hole 104, the partition plate through hole 105 and the top plate through hole 106 on the bottom plate 101, the partition plate 102 and the top plate 103, the bottom plate 101, the partition plate 102 and the top plate 103 form a support body for the installation of the wire stripping tool and the tool adjusting member. At the same time, in cooperation with the bottom plate through hole 104, the partition plate through hole 105 and the top plate through hole 106, the running of the wire stripping tool and the tool adjusting member is guided and limited, which helps to ensure the accuracy of cable cutting.

[0029] In one embodiment, as Figure 1 、 Figure 3 and Figure 4As described above, the wire stripping tool includes a tool chuck 301, a blade 302, and a chuck sheath 304. Among them, the tool chuck 301 includes a chuck rod portion and a chuck end portion. The outer diameter of the chuck rod portion gradually increases towards the chuck end portion, such that the entire tool chuck 301 forms a conical structure. A blade mounting groove 303 is provided at the chuck end portion. The blade 302 is inserted into the blade mounting groove 303. The chuck sheath 304 is sleeved outside the tool chuck 301. Under the elastic force of the adaptive telescopic member 5, the chuck sheath 304 is pushed towards the chuck end portion side. The inner diameter of the chuck sheath 304 is smaller than the outer diameter of the chuck end, so that when the chuck sheath 304 is pushed towards the chuck end, it squeezes the blade mounting groove 303 to clamp the blade 302.

[0030] In the above embodiment, the groove width of the blade mounting groove 303 is greater than the thickness of the blade 302 to facilitate quickly loading the blade 302 into the blade mounting groove 303. At the same time, using the elastic force of the adaptive telescopic member 5 to push the chuck sheath 304 towards the chuck end portion side, and using the chuck sheath 304 to quickly squeeze and clamp the blade 302 in the blade mounting groove 303, the quick installation of the blade 302 can be achieved.

[0031] It should be noted that in this embodiment, the cutting head portion of the blade 302 adopts a semi-circular arc structure. Compared with the traditional flat cutting head, the semi-circular arc cutting head is more conducive to the transmission and contraction of the cutting force.

[0032] In one embodiment, the lower jaw is provided with a horizontal cutting groove 201 and a circumferential cutting groove 202. The horizontal cutting groove 201 and the circumferential cutting groove 202 have the same direction. The blade mounting groove 303 is a cross-shaped knife groove. Corresponding to the horizontal cutting groove 201, the installation direction of the blade 302 in the blade mounting groove 303 is the same as the placement direction of the cable where the horizontal cutting groove 201 is located. Corresponding to the circumferential cutting groove 202, the installation direction of the blade 302 in the blade mounting groove 303 is perpendicular to the placement direction of the cable where the circumferential cutting groove 202 is located.

[0033] In the above embodiment, by setting the blade mounting groove 303 as a cross-shaped knife groove, it is convenient to install the blade 302 according to the needs of circumferential cutting and horizontal cutting. And through the setting of the installation direction of the blade 302, during circumferential cutting, place the cable in the circumferential cutting groove 202. After clamping the cable with the upper jaw body 1 and the lower jaw body, hold the upper cavity body and the lower jaw body and rotate around the cable for one week to achieve circumferential cutting of the cable. At the same time, put the circumferentially cut cable into the horizontal cutting groove 201 and move the cable along the horizontal cutting groove 201 to draw a cut line, so that the insulating layer can be stripped off.

[0034] In one embodiment, as Figure 1 and Figure 5As shown in the figure, the tool adjusting member includes a guide post 4. One end of the guide post 4 is provided with a screw rod section 401, and the other end of the guide post 4 is provided with a dial 402. A threaded deep hole 305 is provided on the chuck rod portion, and the screw rod section 401 is connected to the threaded deep hole 305.

[0035] In the above embodiment, by connecting the guide post 4 and the chuck rod portion in a threaded manner, the overall length of the guide post 4 and the tool chuck 301 can be adjusted, so as to adjust the distance between the tool chuck 301 and the corresponding tangent slot, so as to adapt to cutting different types of cables.

[0036] In one embodiment, as Figures 1 to 5 shown, the tool chuck 301 is slidably installed in the bottom plate through hole 104 and the partition through hole 105. The chuck sheath 304 is installed in the partition through hole 105. The guide post 4 passes through the top plate through hole 106 downward and forms a threaded connection with the chuck rod portion. The dial 402 at the top end of the guide post 4 is restricted at the upper end of the top plate 103 and cannot pass through the partition 102. At the same time, as Figure 2 shown, the partition through hole 105 is provided with a side slot hole 107 in the radial direction. The chuck sheath 304 is provided with a side wall slot hole 308 in the axial direction. The side slot hole 107 and the side wall slot hole 308 are located on the same straight line. The tool chuck 301 is provided with a limiting side slider 306 that is slidably connected to the side slot hole 107 and the side wall slot hole 308.

[0037] In the above embodiment, it can be imagined that when the guide post 4 is rotated by the dial 402, due to the threaded connection between the guide post 4 and the tool chuck 301, and at the same time, since the tool chuck 301 cannot rotate due to the restriction of the side slot hole 107 by the limiting side slider 306, the lifting of the tool chuck 301 can be realized by rotating the guide post 4, so as to adjust the distance between the blade 302 and the corresponding tangent slot, meeting the requirements of stripping different types of wire harnesses.

[0038] In one embodiment, as Figure 3 shown, the limiting side slider 306 is provided with scale lines 307. In this embodiment, it can be imagined that different types of wire harnesses need to adjust the stripping tool to different heights correspondingly. In order to clearly know whether the height of the stripping tool adjustment meets the stripping requirements, scale lines 307 are provided on the limiting side slider 306. During the process of adjusting the lifting of the tool chuck 301 by rotating the guide post 4, the position of the stripping tool can be clearly determined through the scale lines 307, so as to quickly adjust the stripping tool to the height required for stripping.

[0039] In one embodiment, as Figure 1 shown, the adaptive telescopic member 5 is a spring. The spring is sleeved on the guide post 4 and abuts between the top plate 103 and the chuck sheath 304.

[0040] In this embodiment, the outer diameter of the collet sheath 304 is larger than that of the spring. It can be imagined that after adjusting the height of the tool, the distance between the spring between the top plate 103 and the collet sheath 304 is set. Therefore, when the cable is placed in the corresponding tangent groove, the upper clamp body 1 and the lower clamp body are closed under the action of the torsion spring, and the distance between the spring between the top plate 103 and the collet sheath 304 is set, so that the pressing force of the spring is determined, and thus the stripping of the insulating layer can be completed without damaging the wire harness shielding layer.

[0041] Based on the above content, it can be found that by slidably installing the tool collet 301 in the bottom plate through hole 104 and the partition through hole 105, the tool collet 301 can pass through the bottom plate through hole 104 and approach the tangent groove. At the same time, the tool collet 301 is restricted by the side slot hole 107 and cannot rotate. Since the tool collet 301 is threadedly connected to the guide post 4, when the guide post 4 is rotated, the tool collet 301 will move up and down in the vertical direction to adjust the distance between the blade 302 and the corresponding tangent groove. Moreover, under the action of the spring, the collet sheath 304 is pushed towards the collet end by the elastic force of the spring, forming a squeeze on the blade mounting groove 303 and clamping the blade 302 in the blade mounting groove 303. And the spring provides pressure for the downward pressing of the tool collet 301 to ensure that the insulating layer of the cable can be stripped.

[0042] The specific working principle is as follows: First, according to the cable model, by rotating the guide post 4, the tool collet 301 is moved to adjust the distance between the blade 302 and the cable to be cut. After observing the scale line 307 and the height of the tool collet 301 is adjusted in place, the upper clamp body 1 and the lower clamp body are opened, and the cable to be cut is placed in the V-shaped cutting groove. Then the upper clamp body 1 and the lower clamp body are loosened and clamped on the cable. If there is no spring action at this time, the blade 302 can only fit on the insulating layer and cannot apply pressure to the insulating layer, and it is necessary to rely on manual pressure to cut the insulating layer, resulting in inconsistent force and easy damage to the shielding layer or the wire core. Therefore, by setting the spring, after the tool collet 301 is adjusted to the required height, the distance between the spring between the collet sheath 304 and the top plate 103 is fixed. After the cable is placed in the tangent groove, the torsion spring will surely close the upper clamp body 1 and the lower clamp body. However, the cable will block the tool in the tangent groove. Therefore, during the closing process of the upper clamp body 1 and the lower clamp body, the stripping tool will surely be pushed upward, and when the stripping tool is pushed upward, the spring will be compressed. And when the spring is compressed, the spring needs to return to its original set length. Therefore, the spring exerts a reaction force on the stripping tool, thereby squeezing the stripping tool downward, so that the blade 302 cuts into the insulating layer. And the distance between the spring between the collet sheath 304 and the top plate 103 is fixed, so the depth at which the spring pushes the blade 302 into the insulating layer is fixed, thus avoiding damaging the shielding layer and the wire core when stripping the insulating layer.

[0043] When using this tool, you can first adjust the cutting elasticity of the insulation layer of the stripping tool with the guide post 4 according to the cable specifications. After the adjustment is completed, use the upper clamp body 1 and the lower clamp body to clamp the stripped shielded cable in the circumferential cutting groove 202. Rotate the tool 1-2 circles in the direction perpendicular to the cable, and then the cutting and separation of the insulation layer can be successfully completed. After the cutting is completed, the remaining insulation layer can be directly stripped. Of course, you can also use the horizontal cutting edge to horizontally pull the cable in the horizontal cutting groove 201 to make a "T" - shaped opening, which is convenient for removing the redundant insulation layer, as Figure 6 shown. This stripping method is faster and more reliable, and can reduce the damage to the shielding layer during wire stripping.

[0044] In summary, an adjustable elastic - knife - head wire - harness insulation - layer cutting tool provided by an embodiment of the present application has the following advantages: First: This tool adopts a "clamp" - type design structure. Through the cooperation of the guide post, spring, and stripping tool, the guide post can automatically retract when subjected to a certain pressure. By screwing the guide post to adjust the specifications, length, and compression ratio of the spring, the spring retraction force can be changed, and the downward pressure of the fixed cutting edge can be adjusted to meet the insulation - layer cutting requirements of different - specification wire harnesses. Two stripping tools perpendicular and parallel to the wire harness are respectively designed, and the blades are limited to meet the requirements of circumferential cutting and "T - shaped cutting edge" horizontal cutting of the wire harness.

[0045] Second: This tool can quickly strip the insulation layer of the cable, control the downward pressure of the blade with a fixed elasticity, and avoid damaging the cable shielding layer and the wire core.

[0046] Third: This tool can solve the problems that traditional rotary knives cannot cut the insulation layer of twisted - pair cables and are prone to damage the shielding layer and wire core, and improve the assembly quality; Fourth, this tool can be adapted to the use of cables with multiple shapes, can perform circumferential cutting and horizontal cutting of the wire - harness insulation layer, is easy to use, and has a wide application range.

[0047] The above - mentioned are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
