Description

Technical Field

[0001] This utility model relates to the technical field of cable sheath processing equipment, and in particular to a three-wire plug cable assembly device. Background Technology

[0002] The assembly of the internal three-strand wires and plugs involves multiple steps, including outer sheath cutting, outer sheath removal, internal wire splitting, further inner sheath removal, and plug welding. Currently, the common method for cutting the outer sheath of the cable is to use two parallel blades connected to a cylinder. When the cable reaches the cutting area, the blades cut into the sheath and rotate the cable. However, this method has a complex clamping structure, and the internal wires are easily damaged during cable rotation. Furthermore, the cutting effect is relatively poor, which is not conducive to actual production. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a three-wire plug cable assembly device in response to the above-mentioned technical deficiencies. By driving the cutting part to rotate, the device can perform circumferential cutting of the cable. The device has a simple structure, is easy to maintain, and maintains a certain cutting depth to avoid damage to the internal circuitry.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model includes: a base, a rotating shaft, a pull plate, and a driven rod; the base is respectively provided with a control motor and a thrust component, and a clamp is provided at the front of the base; the middle part of the rotating shaft is connected to the base, one end is connected to the control motor, and the other end is provided with a mounting component, on which cutting components are symmetrically provided; the rear of the pull plate is connected to the thrust component and is concentrically arranged with the rotating shaft; the middle part of the driven rod is slidably connected to the mounting component, and can maintain contact between one end and the pull plate while rotating with the mounting component, and the other end is provided with a trigger block that contacts the cutting component.

[0005] Preferably, the pull plate is provided with an annular groove, and the end of the driven rod is provided with a disc that contacts the annular groove.

[0007] Preferably, the thrust component is a cylinder.

[0008] Preferably, the pull plate is provided with symmetrical sliding rods that penetrate the base, and one of the sliding rods is fixedly connected to the thrust member.

[0009] Preferably, the clamp uses pneumatic fingers.

[0010] Preferably, the cutting component includes an arm body, a blade, and a first spring; the arm body is connected to the mounting component, and a placement groove is provided at the front end, with guide posts symmetrically arranged in the placement groove; the blade penetrates the bottom surface of the placement groove and is slidably connected to the guide posts, and a driven block that contacts the trigger block is provided above the blade; the first spring is fitted onto the guide posts.

[0011] Preferably, the arm body is provided with a sliding column that is slidably connected to the mounting component, and the sliding column is provided with a second spring. The end of the sliding column is provided with a hook plate, and the driven rod is provided with a push plate.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The pull plate drives the driven rod to move, and the cooperation between the trigger block and the driven block triggers the two blades to move relative to each other and cut into the cable sheath to a certain depth. Under the drive of the rotating shaft, it rotates 180 degrees to complete the circumferential cutting operation, which greatly improves the cutting efficiency and cutting quality and avoids damage to the internal circuit.

[0014] 2. The sliding connection between the arm and the mounting parts, using the push plate to reach the designated position to drive the hook plate, can realize the peeling operation after ring cutting, simplifying the processing steps and saving processing time;

[0015] 3. The connection between the annular groove and the disc does not affect the rotation of the driven rod during the rotation of the mounting part, and maintains the connection between the two, which is stable and reliable. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] Specific implementation method one: Combining Figure 1-9 As shown, a three-wire plug cable assembly device includes: a base 1, a rotating shaft 2, a pull plate 3, and a driven rod 4; the base 1 is respectively provided with a control motor 101 and a thrust member 102, and a clamp 103 is provided at the front of the base 1, which is located at the front end of the mounting member 201; the middle part of the rotating shaft 2 is connected to the base 1 by bearing support, one end is connected to the control motor 101 by a coupling, and the other end is welded to the mounting member 201. The structure of the mounting member 201 is C-shaped, which will not interfere with the passage of the cable. At the same time, the mounting member 201 is symmetrically provided with cutting members 5; the pull plate 3 is fixedly connected to the thrust member 102 at the rear and is arranged concentrically with the rotating shaft 2; the middle part of the driven rod 4 is slidably connected to the mounting member 201, and can keep one end in contact with the pull plate 3 while rotating with the mounting member 201, and the other end is provided with a trigger block 401 that contacts the cutting member 5;

[0028] When in use, the conveyor belt with clamping function (see...) Figure 9 The device moves the cable sequentially between the mounting parts 201, i.e., the cutting area formed by the two cutting parts 5. Then, the clamp 103 assists in clamping the cable end to keep the cable stable. The pusher 102 drives the pull plate 3 to move backward, and the trigger block 401 pushes the relative displacement of the blade tip of the cutting part 5 to cut into the cable sheath to a certain depth. Then, the motor 101 drives the rotating shaft 2 to rotate 180 degrees to complete the circumferential cutting of the cable. After the pull plate 3 and the clamp 103 are reset, it can wait for the next cable to be cut. The device adopts a circumferential cutting method, which can maintain a certain cutting depth, facilitates the stripping, and avoids damage to the internal circuit. Moreover, the overall structure is relatively simple and convenient for later maintenance.

[0029] Preferred embodiments, in combination Figure 4 As shown, the pull plate 3 is provided with an annular groove 301, and the end of the driven rod 4 is provided with a disc 402 that contacts the annular groove 301. The two are connected to achieve axial limiting of the driven rod 4 and do not affect the driven rod 4 from rotating with the mounting part 201. In order to reduce the contact friction between the two, lubricating oil can be applied inside the annular groove 301 to reduce the contact wear between the two.

[0030] Preferred embodiments, in combination Figure 7 As shown, the mounting component 201 is provided with a positioning hole 202 that is slidably connected to the driven rod 4. The positioning hole 202 has a rectangular cross-sectional shape, and the rectangular structure can improve the positioning stability after the driven rod 4 is connected.

[0031] Preferred embodiments, in combination Figure 2 As shown, the thrust component 102 uses a cylinder, which has a rapid response and sensitive start-up. A hydraulic cylinder structure can also be used, but the operating speed is relatively slow.

[0032] Preferred embodiments, in combination Figure 2-4 As shown, a sliding rod 302 is symmetrically provided behind the pull plate 3, which passes through the base 1. The two form a sliding connection, which can improve the movement stability of the pull plate 3 and reduce the force on the thrust member 102 itself. One of the sliding rods 302 is fixedly connected to the thrust member 102.

[0033] Preferred embodiments, in combination Figure 1 As shown, clamp 103 uses pneumatic fingers, and Y-shaped clamp fingers that open to both sides are preferred to avoid affecting the normal passage of cables; if flat clamp fingers are used, a lifting structure that can drive the clamp to move up and down must be designed, such as a pneumatic rod or slide rail.

[0034] Preferred embodiments, in combination Figure 3-7 As shown, the cutting component 5 includes an arm body 6, a blade 7, and a first spring 8. The arm body 6 is welded to the mounting component 201. The front end of the arm body 6 is provided with a vertically arranged placement groove 601, and guide posts 602 are symmetrically arranged in the placement groove 601. The blade 7 penetrates the bottom surface of the placement groove 601 and is slidably connected to the guide post 602. A driven block 701 is provided above the blade 7 and contacts the trigger block 401. The first spring 8 is fitted on the guide post 602, with its bottom end in contact with the bottom surface of the placement groove 601 and its top end in contact with the blade 7. By displacing the trigger block 401, the inclined structure pushes the driven block 701 to overcome the elastic force of the first spring 8, causing the blade 7 to move downward. After the blade 7 reaches its maximum stroke, it is positioned. At this time, the two blades 7 cut into the cable sheath to a certain depth and, with the subsequent rotation of the mounting component 201, complete the circumferential cutting operation.

[0035] In a preferred embodiment, in order to achieve the peeling operation after circumcision, combined with Figure 3-7 As shown, two sliding columns are welded onto the arm body 6, forming a sliding connection with the mounting component 201. A second spring 604 is provided on the sliding column 603, with one end of the second spring 604 contacting the arm body 6 and the other end contacting the mounting component 201. A hook plate 605 extending towards the driven rod 4 is provided at the end of the sliding column 603, while a push plate 403 extending a certain distance towards the center is provided on the driven rod 4. After the circumferential cutting operation is completed, the driven rod 4 continues to move a certain distance through the pusher 102. The push plate 403 contacts the hook plate 605 and overcomes the elastic force of the second spring 604, pushing the two arm bodies 6 to move a certain distance backward. The outer sheath of the circumferentially cut cable is pushed off by the blade 7, which can simplify one production process and improve work efficiency.
