Description

Technical Field:

[0001] The utility model relates to the technical field of terminal wire processing equipment, and particularly refers to a wire clamping and locking device. Background Art:

[0002] A wire usually consists of a wire harness, a coating layer, a shielding shell, and a terminal interface. During its processing, the two ends of the wire need to be peeled successively first, and then a terminal is installed at one end, and an aluminum shell is wrapped at the other end. The existing processing method uses a peeling device, which includes a turntable, and a front peeling tool holder, a rear peeling tool holder, and an aluminum shell wrapping mechanism arranged along the rotation direction of the turntable. When in use, first peel the front end of the wire with the front peeling tool holder, then clamp this end on the turntable and cut it into small sections of wire by the front peeling tool holder; rotate the turntable, peel the rear end of this section of wire with the rear peeling tool holder; rotate the turntable, and use the aluminum shell wrapping mechanism to wrap an aluminum shell on the exposed copper wire at the rear end.

[0003] Between the rear peeling tool holder and the aluminum shell wrapping mechanism, there is a height difference, and the working height of the rear peeling tool holder needs to be higher than that of the aluminum shell wrapping mechanism. This is because the aluminum shell wrapping mechanism includes a cavity arranged below and a pressing end placed above. First, place an aluminum strip in the cavity, then place the exposed copper wire at the rear end of the wire on this aluminum strip, and then press the pressing end to make the aluminum strip press and form an aluminum shell on the copper wire. Therefore, in order to facilitate wrapping the aluminum shell, a height difference is required between the rear peeling tool holder and the aluminum shell wrapping mechanism. However, due to the height difference, it is easy to cause the exposed copper wire at the rear end of the wire to sometimes not be effectively and accurately shelled.

[0004] However, there is a wire locking device existing on the market at present. For example, a Chinese utility model patent application with the patent publication number CN219652155U discloses a wire clamping and locking and disengaging mechanism, which includes: a housing placed at the circumferential end of the turntable, a clamping jaw arranged on the housing, the clamping jaw is vertically slidably arranged on the housing, a claw is rotatably arranged on one side of the clamping jaw, the claw can be stuck on the top of the housing, and a protection structure for preventing the clamping jaw from being disengaged is arranged on the housing. This technical solution can reduce the distance between the wire and the working surface of the aluminum shell wrapping mechanism, and has the advantage of enhancing the accuracy of wire shelling.

[0005] However, this existing wire clamping and locking and disengaging mechanism still has the following deficiencies:

[0006] In this technical solution, the clamp is locked on the housing by clamping the clamp on the top of the housing in a swingable manner. However, when the clamp is locked, the clamp block on the clamp is rotated and fastened to the housing instead of being horizontally moved and plugged. The rotational fastening method is unstable and easily affected by external forces and not properly fastened or even disengaged. In addition, the technical solution is to push the pressing end through the third spring to make the clamp fastened to the housing, but the direction of the elastic force of the third spring is inconsistent with the swing trajectory of the pressing end. Such a structure can easily cause the third spring to move and disengage, causing trouble to the operator.

[0025] The following further describes the utility model in conjunction with specific embodiments and the drawings.

[0026] See Figures 1 to 5 As shown, there is a wire clamping and locking device, which includes: a fixed seat 2 fixed to the peripheral end of the turntable 1, and a locking groove 21 is formed on the fixed seat 2; a wire clamp 3 slidably installed on the fixed seat 2 and used for clamping wires, and a sliding groove 31 is formed on the wire clamp 3; a locking structure 4 arranged on one side of the wire clamp 3 and used to prevent the wire clamp 3 from disengaging from the fixed seat 2; the locking structure 4 includes: a dial block 41 swingably arranged on one side of the wire clamp 3, a bolt 42 slidably arranged in the sliding groove 31, and a locking spring 43 arranged in the sliding groove 31 and used to push the bolt 42 into the locking groove 21. Among them, a first tooth part 411 is formed at the upper end of the dial block 41, and a second tooth part 421 meshing with the first tooth part 411 is formed on the bolt 42. When the dial block 41 is toggled, the dial block 41 toggles the bolt 42 out of the locking groove 21 to complete unlocking.

[0027] In the present invention, unlike the existing structure, the latch 42 is pushed by the locking spring 43 and inserted into the locking groove 21 of the fixing seat 2 from the side in the horizontal direction. The thrust direction of the locking spring 43 is consistent with the sliding direction of the latch 42, and the locking spring 43 is limited in the slide groove 31, so that no movement occurs, thereby ensuring a stable locking effect. In addition, the shifting block 41 is engaged with the second tooth portion 421 of the latch 42 through the first tooth portion 411 to shift the latch 42 to move horizontally, thereby achieving locking and unlocking, thus achieving the purpose of self-locking, being not easily affected by external forces, having an excellent locking effect, bringing convenience to operators, and being suitable for various types of wire terminal processing equipment.

[0028] The shift block 41 is L-shaped or reverse L-shaped, and can be swingably mounted on the slider 32 through the rotating bolt 40. The shift block 41 includes: a first force arm 401 formed with a first tooth portion 411, a second force arm 402 integrally formed with the first force arm 401, and a rotating hole 403 located between the first force arm 401 and the second force arm 402. The slider 32 is provided with a rotating groove 321 corresponding to the rotating hole 403, and the rotating bolt 400 passes through the rotating hole 403 and is inserted into the rotating groove 321. Here, the shift block 41 can swing with the rotating bolt 40 as the central axis of rotation. Different from the existing structure, no spring is provided under the second force arm 402, but a locking spring 43 is provided at the latch 42 to avoid movement.

[0029] The slide groove 31 has a protruding strip 311 protruding from it, which is used to limit the latch 42 in the slide groove 31. The protruding strip 311 is horizontally distributed so that the latch 42 can slide in the horizontal direction. Here, the protruding strip 311 can ensure that the latch 42 moves stably in the slide groove 31 and will not fall out of the slide groove 31. At the same time, the protruding strip 311 reserves space for the second tooth portion 421, which will not affect the shifting block 41 to shift the latch 42.

[0030] The wire clamp 3 includes: a slider 32 slidably clamped on the fixed seat 2, an upper clamping block 33 fixed to the lower end of the slider 32 and used to clamp the wire, a pull rod 34 passing through the upper clamping block 33 and capable of sliding up and down relative to the upper clamping block 33, a lower clamping block 36 fixed to the lower end of the pull rod 34 and located below the upper clamping block 33, and a wire clamp spring 35 arranged on the slider 32 and pushing the pull rod 34 upwards. The sliding groove 31 is opened on the slider 32.

[0031] The slider 32 has a through hole 322 on the upper wall of the slide slot 31, and a pressing piece 323 is provided on the through hole 322 for the locking spring 43 to abut against. An adjusting bolt 324 is also inserted on the pressing piece 323, and the adjusting bolt 324 is inserted downward into the through hole 322 and abuts against the upper end surface of the latch 42. Here, the lower end surface of the adjusting bolt 324 abuts against the upper end surface of the latch 42, and the locking degree of the latch 42 can be further adjusted by adjusting the tightness between the adjusting bolt 324 and the latch 42. For example, when the latch 42 is inserted into the lock slot 21, the adjusting bolt 324 is adjusted downward so that the adjusting bolt 324 presses the latch 42. At this time, the latch 42 will be more firmly locked in the lock slot 21 and less susceptible to external forces, so as to further enhance stability.

[0032] The slider 32 is provided with a through hole 325 for the pull rod 34 to pass through, and the slider 32 is also provided with a wire clamp spring groove 326 for installing the wire clamp spring 35. Here, the pull rod 34 passes through the slider 32 and extends from the bottom of the slider 32 to be connected and fixed with the lower clamp block 36.

[0033] See Figure 3 and Figure 4 As shown, the pull rod 34 is in an inverted L shape, and the pull rod 34 includes a connecting section 341 that is inserted into the through hole 325 and connected to the lower clamping block 36, and a bending section 342 that is integrally formed with the connecting section 341 and extends laterally to the top of the wire clamp spring slot 326. The wire clamp spring 35 is disposed between the bending section 342 and the wire clamp spring slot 326 and pushes the pull rod 34 upward. Here, when the bending section 342 of the pull rod 34 is pushed up by the wire clamp spring 35, the pull rod 34 will synchronously drive the lower clamping block 36 upward, so that the lower clamping block 36 is close to the upper clamping block 33, forming a clamping action to stably clamp the wire.

[0034] The fixed seat 2 is formed with a slide rail 22, and the slider 32 is protrudingly formed with a slide protrusion 329. The slider 32 is slidably arranged in the slide rail 22 through the slide protrusion 329, so that the wire clamp 3 is detachably connected to the fixed seat 2. Here, when locking is required, the slide protrusion 329 is manually aligned with the slide rail 22, and the second force arm 402 is moved to retract the latch 42, and the slider 32 is pushed upward at the same time. At this time, the locking spring 43 is in a compressed state, and the latch 42 shrinks in the slide groove 31. Further, until the latch 42 is aligned with the lock groove 21, the locking spring 43 will push the latch 42 and insert the latch 42 into the lock groove 21, and the locking is completed; when unlocking is required, the second force arm 402 is moved to drive the first force arm 401 to drive the latch 42 to slide backward through the first tooth portion 411 until it is completely out of the lock groove 21, that is, the unlocking is completed.

[0035] The turntable 1 is vertically provided with a plurality of connection holes 11, the upper end surface of the fixing seat 2 is provided with a lift piece 23, the lower end of the fixing seat 2 is provided with a connection bolt 24, and a limit tension spring 25 is provided between the lift piece 23 and the connection bolt 24. The limit tension spring 25 passes through the connection hole 11 to further connect with the turntable 2, and can further prevent the fixing seat 2 from accidentally falling out when the device is running.

[0036] One end of the lifter 23 extends to the top of the connection hole 11 and is provided with a first buckle hole 231. The other end of the lifter 23 extends to the top of the slider 32 and limits the slider 32 in the vertical direction. The cap of the connecting bolt 24 extends to the bottom of the connection hole 11. One end of the limiting tension spring 25 is connected to the first buckle hole 231, and the other end of the limiting tension spring 25 is connected to the connecting bolt 24. Here, the connecting bolt 24 is also provided with a protective plate 28 for preventing the wire from being entangled with the turntable 1.

[0037] In summary, in the present invention, unlike the existing structure, the latch 42 is pushed by the locking spring 43 and inserted into the lock slot 21 of the fixing seat 2 from the side in the horizontal direction. The thrust direction of the locking spring 43 is consistent with the sliding direction of the latch 42, and the locking spring 43 is limited in the slide slot 31, so that no movement occurs, thereby ensuring a stable locking effect. In addition, the shifting block 41 is engaged with the second tooth portion 421 of the latch 42 through the first tooth portion 411 to shift the latch 42 to move horizontally, thereby achieving locking and unlocking, thus achieving the purpose of self-locking, not easily affected by external forces, and having an excellent locking effect, which brings convenience to operators and is suitable for various types of wire terminal processing equipment.
