Description

Technical Field

[0001] This invention relates to the field of wire harness cutting technology, and more particularly to a cutting device for wire harness processing. Background Technology

[0002] As an important component of the automotive electrical system, the high-voltage wiring harness shielding layer of new energy vehicles has the main function of preventing electromagnetic interference, ensuring the safety of electronic equipment and personnel inside the vehicle, effectively isolating the strong electromagnetic field generated by the high-voltage circuit, and protecting the surrounding electronic equipment and lines from interference, thereby ensuring the normal operation of the vehicle.

[0003] When cutting wire harnesses, the shielding layer needs to be cut and flipped to ensure that it can be firmly connected to the metal shell of the connector and the vehicle body to the greatest extent possible, forming a continuous and low-resistance grounding path. Existing cutting devices usually use multiple ring-shaped blades to make circumferential cuts when cutting the shielding layer, which can easily damage the surface of the inner insulation layer of the wire harness. The damaged area will gradually carbonize, eventually leading to complete insulation failure and instantaneous high-voltage breakdown. The high voltage may directly strike the shielding layer or the metal shell of the connector, causing a short circuit and burning the wire harness, or even causing a fire. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a cutting device for wire harness processing.

[0005] The technical solution is as follows: A cutting device for wire harness processing includes a base, on which a clamp is mounted, and a cutting mechanism disposed on the base. The cutting mechanism includes an electric guide rail mounted on the base, a slide rod slidably mounted inside the electric guide rail, a collar fixedly connected to the slide rod, a cutting tube slidably connected inside the collar, a limiting mechanism and a pushing mechanism disposed inside the cutting tube, the pushing mechanism including a plurality of pushing blocks equidistantly distributed and slidably connected through the cutting tube, a plurality of sets of inclined grooves opened inside the collar, a slide shaft located in the inclined grooves fixedly connected through the pushing blocks, a flipping mechanism disposed inside the cutting tube, and a ring driven by an electric push rod disposed on the base, the ring cooperating with the cutting tube.

[0006] As a further preferred embodiment, the pushing mechanism also includes a limiting frame fixed to the base, and an elastic telescopic rod is fixed to the end of the cut tube, the telescopic end of the elastic telescopic rod sliding through the limiting frame.

[0007] As a further preferred embodiment, the limiting mechanism includes a sleeve that is slidably fitted on the cut tube, the sleeve being fixedly connected to the collar, a through groove being provided on the cut tube, a locking rod being elastically slidably connected in the through groove, and a locking groove matching the locking rod being provided on the inner wall of the sleeve.

[0008] As a further preferred embodiment, the limiting mechanism also includes a support rod fixed to the limiting frame, the support rod cooperating with the locking rod.

[0009] As a further preferred embodiment, the flipping mechanism includes a first piston cylinder fixed to the base, a first compression spring provided between the fixed end and the piston end of the first piston cylinder, a first sleeve slidably sleeved on the piston end of the first piston cylinder, a second compression spring provided between the first sleeve and the piston end of the first piston cylinder, a first L-shaped tube connected to the fixed end of the first piston cylinder, a first air guide tube fixedly connected through the cut tube, and the first air guide tube and the first L-shaped tube connected through a first flexible tube.

[0010] As a further preferred embodiment, the flipping mechanism also includes a first cut plate that is slidably connected through the first L-shaped tube.

[0011] As a further preferred embodiment, the flipping mechanism also includes a first L-shaped plate fixedly attached to the first cut plate, a first tension spring being provided between the first L-shaped plate and the first L-shaped tube, and a T-shaped rod that cooperates with the first L-shaped plate being fixedly attached to the slide rod.

[0012] As a further preferred embodiment, a second piston cylinder is fixedly connected to the base on the side of the electric guide rail away from the first piston cylinder. A one-way valve is installed on the fixed end of both the first and second piston cylinders. A third compression spring is provided between the fixed end and the piston end of the second piston cylinder. A second sleeve is slidably fitted onto the piston end of the second piston cylinder. A fourth compression spring is provided between the second sleeve and the piston end of the second piston cylinder. A second L-shaped tube is connected to the fixed end of the second piston cylinder. A second air guide tube is fixedly connected through the tube. The second air guide tube and the second L-shaped tube are connected through a second flexible tube.

[0013] As a further preferred embodiment, a second section plate is slidably connected through the second L-shaped tube.

[0014] As a further preferred embodiment, a second L-shaped plate that cooperates with the T-shaped rod is fixedly connected to the second cut plate, and a second tension spring is provided between the second L-shaped plate and the second L-shaped tube.

[0015] Compared with the prior art, the present invention has the following advantages: 1. This invention, by setting up a cutting mechanism and a pushing mechanism, compared with the prior art of circumferentially cutting the shielding layer, pushes and expands the shielding layer through the pushing block during the movement of the collar, and then cuts the shielding layer through the cooperation of the cutting tube and the ring. This can effectively avoid damage to the inner insulation layer of the wire harness and prevent accidents caused by the wire harness during use. By setting up a flipping mechanism, the shielding layer can be automatically flipped after being cut, without the need for flipping the shielding layer through other equipment, thus reducing the processing cost of the wire harness.

[0016] 2. By setting a limiting mechanism, when the shielding layer is cut and the slide bar slides to the right, the cut shielding layer can move to the right under the action of the pushing block, so that the subsequently cut shielding layer can be removed from the wire harness.

[0017] 3. By setting a second piston cylinder and a second air guide pipe, when the slide rod squeezes the second sleeve, the piston end of the second piston cylinder is contracted, which enables the second air guide pipe to blow airflow towards the cut shielding layer. Under the action of the airflow, the cut shielding layer can automatically detach from the wire harness and move out of the cut pipe, thus completing the automatic discharge.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances. Example 1

[0021] A cutting device for wire harness processing, such as Figures 1 to 3 As shown, the device includes a base 1, on which a clamp 100 is mounted, and a cutting mechanism mounted on the base 1. The cutting mechanism includes an electric guide rail 201 mounted on the base 1, a slide rod 202 slidably mounted inside the electric guide rail 201, a collar 203 fixedly connected to the slide rod 202, a cutting tube 204 slidably connected inside the collar 203, a limiting mechanism for limiting the collar 203 inside the cutting tube 204, and a pushing mechanism. The pushing mechanism includes four pushing blocks 205 equidistantly distributed and slidably connected through the cutting tube 204. The inner wall of the collar 203 has four sets of inclined grooves. A slide shaft 206 located in the inclined groove is fixedly connected through the pushing block 205. A flipping mechanism is provided inside the cutting tube 204. An electric push rod 207 located on the left side of the electric guide rail 201 is mounted on the base 1. A circular ring 208 is fixedly connected to the telescopic end of the electric push rod 207. The circular ring 208 cooperates with the cutting tube 204.

[0022] It should be noted that the clamp 100 is a conventional clamping device in the field, and its specific structure and working principle are existing technologies, which will not be described in detail here.

[0023] like Figure 4As shown, the pushing mechanism also includes a limiting frame 301 fixed to the base 1, and an elastic telescopic rod 302 fixed to the right end of the cutting tube 204. The telescopic end of the elastic telescopic rod 302 slides through the limiting frame 301.

[0024] like Figure 4 and Figure 5 As shown, the limiting mechanism includes a sleeve 401 that is slidably sleeved on the cut tube 204. The sleeve 401 is fixedly connected to the right end of the collar 203. A through groove is provided on the cut tube 204. A locking rod 402 is elastically slidably connected in the through groove along the vertical direction. A locking groove matching the locking rod 402 is provided on the top of the inner wall of the sleeve 401.

[0025] like Figure 4 and Figure 5 As shown, the limiting mechanism also includes a support rod 501 fixed to the top left side of the limiting frame 301, and the support rod 501 cooperates with the locking rod 402.

[0026] Initially, the clamp 100 is in the open state, the four pushing blocks 205 are far apart, the slide bar 202 is located at the right end of the electric guide rail 201, the telescopic end of the elastic telescopic rod 302 is in the retracted state, the fixed end of the elastic telescopic rod 302 abuts against the limit frame 301, the locking rod 402 is in the elastically retracted state under the pressure of the support rod 501, and the top of the locking rod 402 is retracted into the through groove of the cutting tube 204. First, the wire harness is placed on the clamp 100 to clamp and fix the wire harness, and the shielding layer of the wire harness passes through the ring 208 and extends into the cutting tube 204. Then, the slide bar 202 is controlled to slide to the left by the electric guide rail 201, and the slide bar 202 drives the collar 203. Moving to the left, the collar 203 drives the cutting tube 204, the sleeve 401, and the locking rod 402 to move to the left. The telescopic end of the elastic telescopic rod 302 slides along the limiting frame 301. The locking rod 402 gradually releases its elasticity and slides away from the support rod 501. Then, the telescopic end of the elastic telescopic rod 302 abuts against the limiting frame 301. Because the telescopic end of the elastic telescopic rod 302 is elastic, the elastic telescopic rod 302 drives the cutting tube 204 to stop moving. The sliding rod 202 continues to slide to the left and drives the collar 203 to slide to the left along the outer wall of the cutting tube 204. The collar 203 drives the sleeve 401 to slide to the left along the outer wall of the cutting tube 204. The four pushing blocks 20 The sliding shaft 206 on the 5th is squeezed by the four sets of inclined grooves in the collar 203, causing the four pushing blocks 205 to slide closer to each other. Then, the four pushing blocks 205 contact the shielding layer of the wire harness and squeeze it slightly. At the same time, the sleeve 401 contacts and squeezes the locking rod 402. The locking rod 402 is elastically contracted and slides under force until the locking groove of the sleeve 401 is aligned with the locking rod 402. The locking rod 402 elastically releases and slides into the locking groove to limit the sleeve 401. At this time, the sliding shaft 206 abuts against the end of the corresponding inclined groove. The sliding rod 202 continues to move, which causes the four pushing blocks 205 to squeeze the cutting tube 204 together. The cutting tube 204 is forced to move to the left, and the elastic telescopic rod 30 The telescopic end of 2 extends under force, and the four pushing blocks 205 apply friction to the shielding layer of the wire harness, causing the shielding layer to slide and accumulate to the left. The diameter of the shielding layer near the outer shielding layer gradually increases as it accumulates. Then, the left end of the cutting tube 204 contacts the accumulated shielding layer and pushes the shielding layer closer to the ring 208 until the cutting tube 204 abuts against the ring 208. The cutting tube 204 cuts the shielding layer, but the shielding layer for grounding is still left on the wire harness. This completes the cutting of the shielding layer. At this time, the telescopic end of the electric push rod 207 retracts, causing the ring 208 to move to the left, moving the ring 208 away from the cut position of the shielding layer, so as to facilitate the subsequent flipping of the shielding layer. Example 2

[0027] like Figure 6 , Figure 7 and Figure 9As shown, the flipping mechanism includes a first piston cylinder 601 fixed to the base 1. A first compression spring is provided between the fixed end and the piston end of the first piston cylinder 601. A first sleeve 602 is slidably sleeved on the piston end of the first piston cylinder 601. A second compression spring is provided between the inner wall of the first sleeve 602 and the piston end of the first piston cylinder 601. The elastic force of the second compression spring is greater than that of the first compression spring. A first L-shaped tube 603 is connected to the fixed end of the first piston cylinder 601. A first air guide tube 604 is fixedly connected through the cut tube 204. The first air guide tube 604 and the first L-shaped tube 603 are connected through a first flexible tube.

[0028] like Figure 7 As shown, the flipping mechanism also includes a first cut-off plate 701 that is slidably connected through the first L-shaped tube 603. The first cut-off plate 701 is used to control whether the air inside the first L-shaped tube 603 is circulated.

[0029] like Figure 7 and Figure 8 As shown, the flipping mechanism also includes a first L-shaped plate 801 fixed to the left side of the first cut plate 701, a first tension spring is provided between the first L-shaped plate 801 and the first L-shaped tube 603, and a T-shaped rod 802 that cooperates with the first L-shaped plate 801 is fixed to the front side of the slide rod 202.

[0030] like Figures 8-10 As shown, a second piston cylinder 901 located on the right side of the electric guide rail 201 is fixedly connected to the base 1. A one-way valve for air intake is installed on the fixed end of both the first piston cylinder 601 and the second piston cylinder 901. A third compression spring is provided between the fixed end and the piston end of the second piston cylinder 901. A second sleeve 902 is slidably sleeved on the piston end of the second piston cylinder 901. A fourth compression spring is provided between the inner wall of the second sleeve 902 and the piston end of the second piston cylinder 901. The elastic force of the fourth compression spring is greater than that of the third compression spring. A second L-shaped tube 903 is connected to the fixed end of the second piston cylinder 901. A second air guide tube 904 is fixedly connected through the cut tube 204. The airflow blown out by the first air guide tube 604 flows to the left, and the airflow blown out by the second air guide tube 904 flows to the right. The second air guide tube 904 and the second L-shaped tube 903 are connected through a second flexible tube.

[0031] like Figure 10 As shown, a second cutting plate 1001 is slidably connected through the second L-shaped tube 903. The second cutting plate 1001 is used to control whether the air inside the second L-shaped tube 903 is circulated.

[0032] like Figure 10 As shown, a second L-shaped plate 1101 that cooperates with the T-shaped rod 802 is fixedly connected to the right side of the second cut plate 1001, and a second tension spring is provided between the second L-shaped plate 1101 and the second L-shaped tube 903.

[0033] Initially, slide bar 202 abuts against second sleeve 902, third compression spring is in contracted state, fourth compression spring is in released state, T-shaped rod 802 abuts against second L-shaped plate 1101, second tension spring is in extended state, and inner cavity of second L-shaped tube 903 is in connected state. After cutting the shielding layer of the wire harness, the remaining shielding layer on the wire harness needs to be flipped to ground the wire harness. When slide bar 202 slides to the left, slide bar 202 drives T-shaped rod 802 to move to the left, and second tension spring gradually contracts, driving second L-shaped plate 1101 to slide to the left. Plate 1101 drives the second cutting plate 1001 to slide to the left. The third compression spring gradually releases, causing the piston end of the second piston cylinder 901 to gradually extend. External air enters the inner cavity of the second piston cylinder 901 through the one-way valve on the second piston cylinder 901. The piston end of the second piston cylinder 901 drives the second sleeve 902 to move to the left through the fourth compression spring until the second cutting plate 1001 abuts against the inner wall of the second L-shaped tube 903, cutting off the inner cavity of the second L-shaped tube 903. The second L-shaped plate 1101 stops moving, the third compression spring is fully released, and the T-shaped rod 802 continues to move... The wire harness moves to the left. At this point, the shielding layer has slid and accumulated to the left under the action of the four pushing blocks 205. The slide bar 202 continues to slide to the left until it contacts the first sleeve 602. The slide bar 202 squeezes the first sleeve 602. Because the first cutting plate 701 abuts against the inner wall of the first L-shaped tube 603, the air in the inner cavity of the first piston cylinder 601 cannot be discharged, making the piston end of the first piston cylinder 601 unable to move. The first sleeve 602 slides to the left under force, and the second compression spring contracts under force. Subsequently, the T-shaped rod 802 contacts and squeezes the first L-shaped plate 801, and the first L-shaped plate 801 is subjected to force. The first cutting plate 701 is slid to the left, the first tension spring is stretched under force, and the sliding of the first cutting plate 701 connects the inner cavity of the first L-shaped tube 603. Since the elastic force of the second compression spring is greater than that of the first compression spring, the second compression spring is released quickly, causing the piston end of the first piston cylinder 601 to contract quickly. The first compression spring contracts quickly, and the air in the inner cavity of the first piston cylinder 601 quickly enters the first air guide tube 604 through the first L-shaped tube 603 and the first hose, and is blown to the cut position of the shielding layer through the first air guide tube 604, causing the remaining shielding layer on the wire harness to flip to the left.

[0034] Then, the slide bar 202 is controlled to slide to the right by the electric guide rail 201. The slide bar 202 drives the collar 203 and the T-shaped rod 802 to move to the right. The collar 203 drives the sleeve frame 401 to move to the right. The sleeve frame 401 drives the cutting tube 204 to move to the right through the locking rod 402. The telescopic end of the elastic telescopic rod 302 gradually retracts. The four pushing blocks 205 apply friction to the cut shielding layer, causing the cut shielding layer to move to the right. The first tension spring gradually retracts, driving the first L-shaped plate 801 to slide to the right. The first L-shaped plate 801 drives the first cutting plate 701 to slide to the right. The first compression spring gradually releases. The piston end of the first piston cylinder 601 gradually extends, and external air enters the inner cavity of the first piston cylinder 601 through the one-way valve on the first piston cylinder 601. The piston end of the first piston cylinder 601 drives the first sleeve 602 to move to the right through the second compression spring until the first cutting plate 801 abuts against the inner wall of the first L-shaped tube 603, cutting off the inner cavity of the first L-shaped tube 603. The first L-shaped plate 801 stops moving, the first compression spring is fully released, the first sleeve 602 moves back to its original position, the T-shaped rod 802 continues to move to the right, and the sliding rod 202 disengages from the first sleeve 602 and continues to slide to the right until it meets the second... When sleeve 902 contacts, slide rod 202 presses against second sleeve 902. Because the second cut-off plate 1001 abuts against the inner wall of the second L-shaped tube 903, air in the inner cavity of the second piston cylinder 901 cannot escape, preventing the piston end of the second piston cylinder 901 from moving. Second sleeve 902 slides to the right under force, and the fourth compression spring contracts. Subsequently, locking rod 402 contacts support rod 501, and support rod 501 presses against locking rod 402, causing locking rod 402 to elastically contract and slide. After sliding, locking rod 402 disengages from the locking groove of sleeve frame 401. At this time, the telescopic end of elastic telescopic rod 302 fully retracts, and sleeve frame 401 disengages. The restriction allows the collar 203 and the sleeve 401 to slide along the outer wall of the cut tube 204. Simultaneously, the fixed end of the elastic telescopic rod 302 contacts the limiting frame 301, and the T-shaped rod 802 contacts the second L-shaped plate 1101. The limiting frame 301 provides support to the cut tube 204 through the fixed end of the elastic telescopic rod 302, preventing the cut tube 204 from moving. The collar 203 continues to move to the right, and its four inclined grooves press against the sliding shaft 206 inside. The sliding shaft 206, under force, drives the pushing blocks 205 to slide. The four pushing blocks 205 slide away from each other and reset, no longer contacting the cut shielding layer. The T-shaped rod 802 contacts and presses against the second L-shaped plate 1101. The force on the second L-shaped plate 1101 causes the second cut-off plate 1001 to slide to the right. The second tension spring extends under pressure. After the second cut-off plate 1001 slides, the inner cavity of the second L-shaped tube 903 is connected. Because the force of the fourth compression spring is greater than that of the third compression spring, the fourth compression spring quickly releases, causing the piston end of the second piston cylinder 901 to contract rapidly. The third compression spring also contracts rapidly. Air in the inner cavity of the second piston cylinder 901 quickly passes through the second L-shaped tube 903 and the second flexible hose into the second air guide tube 904.The airflow then blows through the second air duct 904 onto the severed shielding layer. Under the influence of the airflow, the severed shielding layer moves to the right, detaches from the wire harness, and exits the cutting tube 204, completing the automatic discharge of the severed shielding layer. This completes the cutting of the entire shielding layer of the wire harness. The clamp 100 can then be opened to remove the wire harness. A new wire harness can then be placed in the clamp 100, and the above steps can be repeated to achieve the same effect.
