DETAILED DESCRIPTION

[0048] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0049] Cable cutting device, see Figure 1-8 As shown, it includes: a cutting mechanism 01 and a guiding mechanism 500. The cutting mechanism 01 is used to cut the outer insulating layer, aluminum foil, braided shielding net, inner insulating layer, etc. of the cable, and the guiding mechanism 500 is used to assist in cutting the braided shielding net, which facilitates the subsequent installation of connecting terminals or connectors.

[0050] like Figure 1-2As shown, the cutting mechanism 01 and the guiding mechanism 500 are installed front and back.

[0051] like Figure 3-6 As shown, the cutting mechanism 01 includes: a knife disc 100, a plurality of auxiliary knives 410, a plurality of main knives 420, a first bracket 210, a second bracket 220, a rotating power assembly 310, a feeding power assembly 320, a central tube 200 and a frame 300.

[0052] like Figure 1 As shown, a structure of the frame 300 is in a frame shape, which acts as a carrier and has a top plate 301, a bottom plate 302, a front side plate 303 and a rear side plate 304, which support various components of the cutting mechanism 01 during installation;

[0053] Of course, the frame 300 can be designed to be other shapes as long as it can play a supporting role.

[0054] The central tube 200 is arranged horizontally, and the central tube 200 is arranged hollow;

[0055] The center of the cutter head 100 forms a wire inlet 101 , the front end of the central tube 200 is inserted into the cutter head 100 , the rear end is supported on the rear side plate 304 of the frame 300 , and the wire inlet 101 corresponds to the front end opening of the central tube 200 .

[0056] The knife disc 100 is made of high-hardness hardware material and is disc-shaped as a whole.

[0057] The cutter disc 100 includes: a main body 110, a mounting disc 120 and a toothed disc 130. The main body 110, the mounting disc 120 and the toothed disc 130 are in an assembled relationship or an integrally formed relationship. The mounting disc 120 is located on the front side of the main body 110, and the toothed disc 130 is located on the rear side of the main body 110. The mounting disc 120 is mainly used to install the auxiliary knife 410 and the main knife 420, and the toothed disc 130 is subsequently cooperated with the rotating power component 310 to drive the cutter disc 100 to rotate.

[0058] There are four auxiliary knives 410 installed on the mounting plate 120, and the four auxiliary knives 410 are arranged around the circumference of the central opening 101. Similarly, there are four main knives 420 installed on the mounting plate 120, and the four main knives 420 are arranged around the circumference of the central opening 101, and the auxiliary knives 410 are located on the outside and the main knives 420 are located on the inside. Figure 7-8 As shown, when viewed from the front, the auxiliary knife 410 blocks the main knife 420 .

[0059] It is worth noting that if Figure 1 As shown, a protective plate is also provided on the front of the cutter head 100. Figure 5-8 As shown, for ease of viewing, the protective plate on the front of the blade disc 100 is hidden.

[0060] Continue as Figure 6 As shown, the first bracket 210 and the second bracket 220 are sleeved on the central tube 200, the auxiliary knife 410 is connected to the first bracket 210 through the connecting rod a430, and a connecting block a211 is provided at the connection, and the main knife 420 is connected to the second bracket 220 through the connecting rod b440, and a connecting block b221 is provided at the connection; the connecting block a211 and the connecting block b221 are both provided with a slide groove 240, and the connecting block a211 connected to the connecting rod a430 connected to the auxiliary knife 410 is fixed to the first bracket 210, and the connecting block b221 connected to the connecting rod b440 connected to the main knife 420 is fixed to the second bracket 220. When the feeding power assembly 320 pushes the first bracket 210 and the second bracket 220 to move along the central tube 200, the connecting rod moves along the slide groove 240.

[0061] Continue as Figure 6 As shown, a mounting groove 121 is provided on the surface of the mounting plate 120, and the connecting rod is connected to the auxiliary knife 410 and the main knife 420 through a connecting arm 450. The connecting arm 450 is installed in the mounting groove. Under the pushing action of the connecting rod, the connecting arm 450 moves along the mounting groove 121, so that the auxiliary knife 410 and the main knife 420 are close to or away from the center of the wire inlet 101.

[0062] The rotating power component 310 is mainly used to drive the cutter disc 100 to rotate. Here, a bearing can be arranged between the front end of the center tube 200 and the cutter disc 100, and the rear end of the center tube 200 is fixed to the rear side plate 304, so that when the cutter disc 100 rotates, the center tube 200 will not rotate with the cutter disc 100; or, the front end of the center tube 200 is fixed to the cutter disc 100, and a bearing is arranged between the rear end of the center tube 200 and the rear side plate 304, so that when the cutter disc 100 rotates, the center tube 200 follows the rotation. Preferably, the center tube 200 does not rotate with the cutter disc 100.

[0063] The central tube 200 of the present embodiment does not rotate with the cutter head 100 ; the first bracket 210 and the second bracket 220 are sleeved on the outside of the central tube 200 via a sleeve 230 .

[0064] Furthermore, the sleeve 230 is sleeved outside the central tube 200 and can move along the central tube 200 under external force; a bearing is arranged between the second bracket 220 and the sleeve 230, and there is no bearing between the first bracket 210 and the sleeve 230. The first bracket 210 is arranged in a floating manner, so that when the cutter disc 100 rotates, the first bracket 210 and the second bracket 220 are assisted by the connecting rod and the connecting block to rotate synchronously with the cutter disc 100.

[0065] Furthermore, the feeding power assembly 320 pushes the first bracket 210 and the second bracket 220 to move relatively along the central tube 200, and the first bracket 210 and the second bracket 220 move in the direction close to the cutter disc 100 and away from the cutter disc 100;

[0066] In the process of the feeding power assembly 320 pushing the first bracket 210 and the second bracket 220 to move along the central tube 200 close to the cutter head 100, the auxiliary cutter 410 and the main cutter 420 will approach the center of the wire inlet 101 for cutting;

[0067] When the feeding power assembly 320 pushes the first bracket 210 and the second bracket 220 to move along the central tube 200 away from the cutter head 100, the auxiliary cutter 410 and the main cutter 420 will move away from the center of the wire inlet 101 to retract the cutter.

[0068] Furthermore, if Figure 6 As shown, the cutter disc 100 is provided with a groove body 140 for a connecting rod to pass through, one end of the connecting rod is limited in the slide groove 240, and the other end passes through the groove body 140 and is connected to the connecting arm 450. At the same time, the connecting rod is limited in the groove body 140 by a pin; during the rotation of the connecting rod around the pin, the connecting arm 450 is pulled to move in the installation groove 121 through the lever principle, thereby driving the auxiliary knife 410 and the main knife 420 to move.

[0069] Furthermore, four auxiliary knives 410 are provided, and each auxiliary knife 410 is provided with a connecting arm 450, a connecting rod a430 and a connecting block a211; similarly, four main knives 420 are provided, and each main knife 420 is provided with a connecting arm 450, a connecting rod b440 and a connecting block b221.

[0070] In the above-mentioned process of cutting, the connecting rod does not move forward and backward. When the first bracket 210 and the second bracket 220 move forward (i.e., move closer to the cutter disc 100), the end of the connecting rod moves along the slide groove 240, and the end of the connecting rod tilts up, and the front end of the connecting rod moves down, pushing the connecting arm 450 to move inward along the mounting groove 121, and the auxiliary knife 410 and the main knife 420 cut;

[0071] During the process of retracting the knife, the connecting rod will not move forward or backward. When the first bracket 210 and the second bracket 220 move backward (i.e., move away from the knife disc 100), the end of the connecting rod moves along the slide groove 240. When the end of the connecting rod is pressed down, the front end of the connecting rod rises, pushing the connecting arm 450 to move outward along the installation groove 121, and the auxiliary knife 410 and the main knife 420 are retracted.

[0072] Furthermore, an elastic member 600 is connected between the first bracket 210 and the second bracket 220, and the first bracket 210 and the second bracket 220 are relatively maintained at the first position by the elastic member 600. During the cutting process, when the auxiliary knife 410 is not subjected to the reaction force of the cable, the first bracket 210 and the second bracket 220 are synchronously moved by the elastic member, that is, there is no relative movement between the two, and the auxiliary knife 410 and the main knife 420 are synchronously cut.

[0073] Specifically, Figure 5 As shown, the elastic member 600 is a tension spring. A plurality of elastic members 600 are arranged between the first bracket 210 and the second bracket 220, so that the force is more balanced. The elastic member 600, i.e., the tension spring, keeps the first bracket 210 and the second bracket 220 in a tightly connected state (position).

[0074] During the cutting process, when the auxiliary knife 410 is subjected to the reaction force of the cable, it overcomes the elastic force of the elastic member 600, causing the first bracket 210 and the second bracket 220 to move relative to each other, that is, the first bracket 210 and the second bracket 220 move away from each other, and the auxiliary knife 410 and the main knife 420 do not cut synchronously.

[0075] like Figure 8 As shown, Figure 8 The state at this time is that the first bracket 210 and the second bracket 220 have produced relative movement, and the main knife 420 is closer to the cable inlet 101 than the auxiliary knife 410. At this time, if the cable has been inserted into the cable inlet 101, the main knife 420 can cut the cable during rotation.

[0076] The specific working principle of the cutting mechanism is further explained below:

[0077] In the initial state, the first bracket 210 and the second bracket 220 are defined as being away from the cutter disc 100, at which time the wire inlet 101 is opened to the maximum, and the auxiliary knife 410 is closer to the center of the wire inlet 101 than the main knife 420;

[0078] Next, the wire is inserted into the conducting port 101 manually or by a wire feeding mechanism;

[0079] The rotating power assembly 310 and the feeding power assembly 320 are started simultaneously;

[0080] The rotary power assembly 310 drives the cutter head 100 to rotate, and the auxiliary cutter 410, the main cutter 420, the first bracket 210, the second bracket 220, etc. also rotate synchronously. At this time, the wire may not be located at the exact center of the wire inlet 101;

[0081] In the process of synchronously feeding the auxiliary knife 410 and the main knife 420 driven by the rotation of the knife disc 100 and the feeding power assembly 320, the wire may first contact a certain auxiliary knife 410, and the auxiliary knife 410 continuously pushes the wire toward the center of the wire inlet 101;

[0082] Until the wire is located at the center of the wire inlet 101 and the plurality of auxiliary knives 410 are subjected to the reaction force of the wire, then, under the reaction force of the wire, the first bracket 210 no longer moves close to the cutter disc 100, the auxiliary knives 410 no longer advance, and the second bracket 220 continues to move close to the cutter disc 100, the main knife 420 continues to advance, and is closer to the center of the wire inlet 101 than the auxiliary knives 410;

[0083] By controlling the feed amount of the main knife 420, the outer insulation layer and the aluminum foil layer of the cable can be cut to expose the braided shielding mesh.

[0084] After the cutting is completed, the feed power assembly 320 pushes the first bracket 210 and the second bracket 220 to retract the knife. During the retraction process, the second bracket 220 moves away from the knife disc 100, and the main knife 420 retracts. Then the first bracket 210 and the second bracket 220 move synchronously away from the knife disc 100 again, and the main knife 420 and the auxiliary knife 410 retract synchronously again.

[0085] After cutting is completed, the wire can be pulled out of the wire inlet 101 .

[0086] During the wire pulling process, the beginning of the wire corresponding to the auxiliary knife 410 is pulled out, and the feed power assembly 320 drives the auxiliary knife 410 to press the beginning of the wire inward, so that the beginning of the braided shielding net opens, which is convenient for subsequent operations.

[0087] In one embodiment, the rotating power assembly 310 includes: a rotating motor 311 and a first belt transmission group 312, the rotating motor 311 is installed on the top plate 301, and an outer gear ring is provided on the outer peripheral side of the gear plate 130;

[0088] The first belt transmission group 312 includes: a transmission wheel 3121 mounted on the output shaft of the rotating motor 311 and a belt 3122 wound between the transmission wheel and the outer gear ring;

[0089] When the rotary motor 311 moves, it drives the cutter head 100 , the first bracket 210 and the second bracket 220 to rotate synchronously around the central tube 200 .

[0090] In one embodiment, the feeding power assembly 320 includes: a feeding motor 321, a second belt transmission group 322, a screw 323 and a push plate 324. The feeding motor 321 is also installed on the top plate 301. The screw 323 is provided with two groups, which are arranged parallel to the central tube 200 and are separated on both sides of the central tube 200. The push plate 324 is installed on the screw 323 through the screw sleeve, and the push plate 324 is fixed to the sleeve 230.

[0091] The second belt drive group 322 includes: a screw drive wheel 3221, a tension wheel 3222, a drive wheel 3223 and a belt 3224; the drive wheel 3223 is installed on the feed motor 321, the screw drive wheel 3221 is installed on the screw 323, and the belt 3224 is wound between the screw drive wheel 3221, the tension wheel 3222 and the drive wheel 3223;

[0092] The belt 3224 drives the screw drive wheel 3221 to rotate, which further drives the screw 323 to rotate. During the rotation of the screw 323, the push plate 324 is pushed to move. The push plate 324 drives the sleeve 230 to move, and then pushes the first bracket 210 and the second bracket 220 to move.

[0093] In one embodiment, the cable cutting device further includes: a catheter mechanism 500;

[0094] The catheter mechanism 500 comprises:

[0095] A first driving member 510, whose output shaft is coaxially arranged with the central tube 200, and a mounting member 520 is fixed to the output shaft;

[0096] The conduit 530 is detachably mounted on the mounting member 520. The first driving member 510 drives the conduit 530 to rotate. The conduit 530 is coaxially arranged with the central tube 200 and is hollow. Its diameter is smaller than that of the central tube 200 and can be inserted into the central tube 200.

[0097] A second driving member 540, wherein the first driving member 510 is mounted on the second driving member 540 through a slider and is driven to move by the second driving member 540, thereby driving the catheter 530 to move in a direction of inserting into or withdrawing from the central tube 200;

[0098] Furthermore, the catheter 530 can pass through the central tube 200 from the front end;

[0099] The first driving member 510 may be a motor, and the second driving member 540 includes: a motor 541 and a screw rod 542. The slider is mounted on the screw rod 541 and is restricted on the slide rail. The motor 541 drives the screw rod 542 to rotate, and the slider moves on the slide rail, thereby driving the first driving member 510 to move, and finally pushing the guide tube 530 to move.

[0100] Optionally, the second driving member 540 may also be selected to have a cylinder and a slide rail. The first driving member 510 is installed on the slide rail through a slider. The cylinder pushes the first driving member to move along the slide rail, which can also push the catheter 530 to move.

[0101] After cutting the outer insulating layer and the aluminum foil, the cutting mechanism 01 also feeds the power assembly 320 to drive the auxiliary knife 410 to press the beginning of the wire inward, so that the beginning of the braided shielding net opens;

[0102] For the convenience of representation, the position where the outer insulation layer and aluminum foil are cut on the cable is defined as a;

[0103] The cable is inserted into the cable inlet 101 again, but the position a does not pass the auxiliary knife 410 and enter the cable inlet 101, that is, Figure 4As shown, the cable is inserted into the cable inlet 101 from left to right, and the position a of the cable is on the left side of the auxiliary knife 410;

[0104] At this time, the first driving member 510 and the second driving member 540 are in operation, pushing the conduit 530 to approach the cutter head 100 during the self-rotation process and insert it between the braided shielding mesh and the inner insulating layer;

[0105] The purpose of the catheter 530 rotating during the movement is to prevent the braided shielding mesh from being pushed by the catheter 530 and stacking backwards, causing the catheter 530 to be unable to be inserted between the braided shielding mesh and the inner insulating layer.

[0106] The catheter 530 moves over the auxiliary knife 410, that is, Figure 3-4 As shown, the conduit 530 moves from right to left, and the left end of the conduit 530 moves to the left side of the auxiliary knife 410, that is, passes through the line inlet 101;

[0107] At this point, the conduit 530 is located between the braided shield and the inner insulation layer;

[0108] Next, the cutting mechanism 01 is activated, and the auxiliary knife 410 and the main knife 420 advance again. By the same principle, the advance amount of the main knife 420 is controlled to cut part of the woven shielding mesh;

[0109] After cutting the braided shield, pull the cable out.
