[0025] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0026] Please refer to Figures 1 to 11 The wire twisting device includes a rotating drive mechanism 1, a base plate 21, a fixed plate 22, a push plate 23, a first Y-axis drive member 31 and a wire twisting assembly 4. The fixed plate 22 and the first Y-axis drive member 31 are respectively arranged on the base plate 21. The first Y-axis drive member 31 is connected to the push plate 23 to drive the push plate 23 to approach or move away from the fixed plate 22. The wire twisting assembly 4 includes a rotating drum 41, an X-shaped clamp 42, a first elastic member 43 and a resistance member 44. The rotating drum 41 is rotatably arranged on the fixed plate 22. The X-shaped clamp 42 is arranged at one end of the rotating drum 41 away from the push plate 23. The first elastic member 43 is used to drive the X-shaped clamp 42 to open. The resistance member 44 is rotatably arranged on the push plate 23. The end of the resistance member 44 close to the fixed plate 22 has a resistance portion 441 for driving the X-shaped clamp 42 to close. The rotating drive mechanism 1 is used to drive the rotating drum 41 to rotate.

[0027] From the above description, it can be seen that the beneficial effects of the present invention are: the wire twisting device has a novel structure and a compact size. Compared with the existing clamping cylinder, the wire twisting assembly 4 in the wire twisting device has a significantly reduced width in the X-axis direction required for its rotation, so that the wire twisting device with the same width size can carry a larger number of wire twisting assemblies 4, so that the wire twisting device can complete the wire twisting work of a larger number of wire handles at a time, which is beneficial to improving the production efficiency of the production line and reducing production costs.

[0028] Furthermore, the X-shaped clamp 42 includes a first claw 421, a second claw 422 and a mounting shaft 423, the first claw 421 and the second claw 422 are rotatably connected via the mounting shaft 423, the mounting shaft 423 is mounted on the rotating cylinder 41, one end of the first claw 421 and one end of the second claw 422 extend out of the rotating cylinder 41 respectively, the other end of the first claw 421 and the other end of the second claw 422 respectively cooperate with the interference portion 441, and the first elastic member 43 contacts the first claw 421 and the second claw 422 respectively.

[0029] As can be seen from the above description, the X-shaped jaw 42 has a simple structure, good working stability, and is easy to process and form.

[0030] Further, the abutting portion 441 is a concave conical surface provided at the end of the abutting member 44.

[0031] As can be seen from the above description, as the length of the abutting member 44 extending into the inside of the rotating cylinder 41 increases, the concave conical surface will drive the clamping ends of the X-shaped jaws 42 to gradually close, so that the X-shaped jaws 42 realize the clamping action.

[0032] Further, the outer wall of the first jaw 421 has a mating conical surface 424 that mates with the concave conical surface.

[0033] As can be seen from the above description, the presence of the mating conical surface 424 can prevent the end of the abutting member 44 from interfering with the end of the X-shaped jaw 42 during the process of the abutting member 44 extending into the rotating cylinder 41, resulting in the twisting assembly 4 being stuck and unable to work. That is, the presence of the mating conical surface 424 can effectively improve the working stability of the twisting assembly 4.

[0034] Further, a first mounting groove 4211 is provided on the first jaw 421, a second mounting groove 4221 is provided on the second jaw 422, one end of the first elastic member 43 is located in the first mounting groove 4211, and the other end of the first elastic member 43 is located in the second mounting groove 4221.

[0035] As can be seen from the above description, the presence of the first mounting groove 4211 and the second mounting groove 4221 can limit the first elastic member 43 and prevent the first elastic member 43 from being displaced, which is beneficial to ensuring the working stability of the twisting assembly 4.

[0036] Further, it further includes a fixing frame 5. A wire head clamping mechanism 6 is provided on the fixing frame 5. The fixing frame 5 includes a base 51. A second Y-axis driving member 32 is provided on the base 51. The second Y-axis driving member 32 is connected to the bottom plate 21 to drive the twisting assembly 4 to approach or move away from the wire head clamping mechanism 6.

[0037] As can be seen from the above description, the wire head clamping mechanism 6 is used to clamp and fix the area of the wire head of the wire bundle that does not need to be twisted. The second Y-axis driving member 32 is used to drive the twisting assembly 4 to avoid the wire head of the wire bundle, ensuring that the wire head of the wire bundle can be accurately moved to the preset twisting position.

[0038] Further, the wire-end clamping mechanism 6 includes a substrate 61, a driving component, a second elastic member 62, a first fixing strip 63 and a second fixing strip 64. The substrate 61 is connected to the fixing bracket 5 and is parallel to the fixing plate 22. The first fixing strip 63 is provided with a first clamping jaw 651, and the second fixing strip 64 is rotatably provided with a second clamping jaw 652. The second elastic member 62 contacts the second fixing strip 64 and the second clamping jaw 652 respectively. The driving component is arranged on the substrate 61 and drives the first fixing strip 63 and the second fixing strip 64 to slide so as to drive the first clamping jaw 651 and the second clamping jaw 652 to open and close. The first clamping jaw 651, the second clamping jaw 652 and the wire-twisting component 4 are arranged in one-to-one correspondence.

[0039] As can be seen from the above description, the structure of the wire-end clamping mechanism 6 is novel and practical. The presence of the second elastic member 62 makes the clamping and fixing structure formed by the first clamping jaw 651 and the second clamping jaw 652 an elastic clamping and fixing structure, which can not only effectively prevent the clamped wire end from being over-clamped and causing cable damage, but also avoid the phenomenon that the clamping force is insufficient and the clamped area of the wire end can be twisted, effectively improving the clamping stability and clamping effect of the wire-end clamping mechanism 6.

[0040] Further, a limiting groove 641 is provided on the second fixing strip 64, and a partial area of the second clamping jaw 652 is located in the limiting groove 641.

[0041] As can be seen from the above description, the presence of the limiting groove 641 can limit the rotation range of the second clamping jaw 652, which is beneficial to ensuring the working stability of the wire-end clamping mechanism 6.

[0042] Further, the wire-end clamping mechanism 6 further includes a first lifting driving member 681 arranged on the fixing bracket 5, and the substrate 61 is connected to the fixing bracket 5 through the first lifting driving member 681.

[0043] As can be seen from the above description, the first lifting driving member 681 is used to drive the first and second clamping jaws to avoid the wire end of the wire bundle, ensuring that the wire end of the wire bundle can be accurately moved to the preset twisting position.

[0044] Further, it further includes a wire-end bending mechanism 69. The wire-end bending mechanism 69 includes a second lifting driving member 691 and a bending plate 692. The second lifting driving member 691 is arranged on the side of the substrate 61 away from the first fixing strip 63, and the second lifting driving member 691 is connected to the bending plate 692.

[0045] As can be seen from the above description, the wire-end bending mechanism 69 is used to bend the wire end of the wire bundle for subsequent station processing.

[0046] Embodiment 1

[0047] Please refer to Figures 1 to 11, Embodiment 1 of the present invention is: a wire twisting device, which is used to twist the core wires of a cable so that the core wires of the cable are wound around each other for subsequent processing. In this embodiment, the wire twisting device is used to twist the wire ends of an electronic mine cable harness.

[0048] Please refer to Figures 1 to 4 , the wire twisting device includes a rotary drive mechanism 1, a base plate 21, a fixing plate 22, a push plate 23, a first Y-axis drive member 31 and a wire twisting assembly 4. The fixing plate 22 and the first Y-axis drive member 31 are respectively arranged on the base plate 21. The fixing plate 22 and the push plate 23 are arranged in parallel. The first Y-axis drive member 31 is connected to the push plate 23 to drive the push plate 23 to approach or move away from the fixing plate 22; the wire twisting assembly 4 includes a rotating cylinder 41, an X-shaped jaw 42, a first elastic member 43 and a contact member 44. The rotating cylinder 41 is rotatably arranged on the fixing plate 22. The X-shaped jaw 42 is arranged at one end of the rotating cylinder 41 away from the push plate 23. The first elastic member 43 is used to drive the X-shaped jaw 42 to open. The contact member 44 is rotatably arranged on the push plate 23. One end of the contact member 44 close to the fixing plate 22 has a contact portion 441 for driving the X-shaped jaw 42 to close; the rotary drive mechanism 1 is used to drive the rotating cylinder 41 to rotate. The rotating cylinder 41 is a cylindrical structure with both ends penetrating. The first Y-axis drive member 31 is used to drive the push plate 23 to move in the Y-axis direction. The first Y-axis drive member 31 can be an electric push rod, a cylinder, a hydraulic rod or other drive mechanisms.

[0049] Specifically, a first mounting hole is provided on the fixing plate 22. One end of the rotating cylinder 41 away from the push plate 23 passes through the first mounting hole. A first bearing 451 is sleeved on the rotating cylinder 41. The rotating cylinder 41 is rotatably mounted on the fixing plate 22 through a first rotating shaft; a second mounting hole 231 is provided on the push plate 23. A part of the contact member 44 is located in the second mounting hole 231. A second bearing 452 is sleeved on the contact member 44. The contact member 44 is rotatably mounted on the push plate 23 through the second bearing 452. It should be noted that in order to allow the reader to clearly see the second mounting hole 231, the contact member 44 and the second bearing 452 are separated from the push plate 23 in the figure. In an actual product, the second bearing 452 should be arranged in the second mounting hole 231, and the contact member 44 is sleeved in the second bearing 452.

[0050] Please refer to Figures 4 to 7, the X-shaped jaw 42 includes a first jaw 421, a second jaw 422 and a mounting shaft 423. The first jaw 421 and the second jaw 422 are rotatably connected by the mounting shaft 423. The mounting shaft 423 is located inside the rotating cylinder 41 and both ends of the mounting shaft 423 are mounted on the rotating cylinder 41. One end of the first jaw 421 away from the push plate 23 and one end of the second jaw 422 away from the push plate 23 respectively extend out of the rotating cylinder 41. The other ends of the first jaw 421 and the second jaw 422 respectively cooperate with the abutting portion 441, and the first elastic member 43 respectively contacts the first jaw 421 and the second jaw 422.

[0051] As a preferred embodiment, the abutting portion 441 is a concave conical surface provided at the end of the abutting member 44. By adjusting the driving distance of the first Y-axis driving member 31, the tightening degree of the X-shaped jaw 42 can be adjusted, so that the wire twisting device can be applicable to cables with different wire diameters. Thus, the wire twisting device has the advantage of strong versatility.

[0052] Further preferably, the outer wall of the first jaw 421 has a mating conical surface 424 that cooperates with the concave conical surface. Similarly, the outer wall of the first jaw 421 has a mating conical surface 424 that cooperates with the concave conical surface. When the X-shaped jaw 42 is opened to the maximum extent under the action of the first elastic member 43, partial areas of the first jaw 421 and the second jaw 422 respectively abut against the inner wall of the rotating cylinder 41. The existence of the mating conical surface 424 can ensure that there is a gap between one end of the first jaw 421 (and one end of the second jaw 422) close to the push plate 23 and the inner wall of the rotating cylinder 41 for the end of the abutting member 44 close to the fixed plate 22 to be inserted, thereby ensuring the working stability of the wire twisting assembly 4. At the same time, the concave conical surface and the mating conical surface 424 are in surface contact fit. Therefore, local excessive wear of the first jaw 421 / second jaw 422 can be prevented, resulting in a decrease in the service life of the wire twisting assembly 4.

[0053] The first elastic member 43 can be a spring, a spring sheet, a torsion spring or a spring washer. In the wire twisting assembly 4 of this embodiment, a spring is selected as the first elastic member 43. For the convenience of spring installation and to avoid accidental displacement of the spring during operation, a first installation groove 4211 is provided on the first jaw 421, a second installation groove 4221 is provided on the second jaw 422, one end of the first elastic member 43 is located in the first installation groove 4211, and the other end of the first elastic member 43 is located in the second installation groove 4221.

[0054] Such as Figure 2 and Figure 3As shown, the rotation drive mechanism 1 can be either a belt drive mechanism or a gear drive mechanism. In this embodiment, the number of the wire twisting assemblies 4 is multiple, and the multiple wire twisting assemblies 4 are arranged in a row. The rotation drive mechanism 1 includes a rotation drive member 11, a driving gear 12, multiple transmission gears 13 and multiple driven gears 14. The driven gears 14 are installed on the rotating cylinder 41, the transmission gears 13 are rotatably installed on the fixing plate 22, and two adjacent driven gears 14 are driven by one transmission gear 13. The rotation drive member 11 is connected to the driving gear 12, and the driving gear 12 is directly meshed with the driven gear 14 closest to it or is drivingly connected through a transmission gear 13. The rotation drive member 11 can be a motor optionally.

[0055] Please refer to Figure 1 and Figure 2 , the wire twisting device further includes a fixing bracket 5, and a wire end clamping mechanism 6 is provided on the fixing bracket 5. The fixing bracket 5 includes a base 51, and a second Y-axis drive member 32 is provided on the base 51. The second Y-axis drive member 32 is connected to the bottom plate 21 to drive the wire twisting assembly 4 to approach or move away from the wire end clamping mechanism 6. The second Y-axis drive member 32 is used to drive the bottom plate 21 to move along the Y-axis direction. The second Y-axis drive member 32 can be an electric push rod, a cylinder, a hydraulic rod or other drive mechanisms optionally.

[0056] Please refer to Figure 8 and Figure 10 , in this embodiment, the wire end clamping mechanism 6 includes a substrate 61, a drive assembly, a second elastic member 62, a first fixing strip 63 and a second fixing strip 64. The substrate 61 is connected to the fixing bracket 5 and is parallel to the fixing plate 22. The first fixing strip 63 is provided with a first clamping jaw 651, the second fixing strip 64 is rotatably provided with a second clamping jaw 652, and the second elastic member 62 is respectively in contact with the second fixing strip 64 and the second clamping jaw 652. The drive assembly is provided on the substrate 61 and drives the first fixing strip 63 and the second fixing strip 64 to slide to drive the first clamping jaw 651 and the second clamping jaw 652 to open and close. The first clamping jaw 651, the second clamping jaw 652 and the wire twisting assembly 4 are arranged in one-to-one correspondence.

[0057] Specifically, the driving assembly includes a first X-axis driving member 661 and a second X-axis driving member 662. The first X-axis driving member 661 is fixed on the substrate 61 and connected to the first fixing strip 63. The second X-axis driving member 662 is fixed on the substrate 61 and connected to the second fixing strip 64. The first X-axis driving member 661 drives the first fixing strip 63 to linearly move along the X-axis to drive the first jaw 651 to approach or move away from the second jaw 652. The second X-axis driving member 662 drives the second fixing strip 64 to linearly move along the X-axis to drive the second jaw 652 to approach or move away from the first jaw 651. When the first X-axis driving member 661 drives the first jaw 651 to approach the second jaw 652 and the second X-axis driving member 662 drives the second jaw 652 to approach the first jaw 651, the first jaw 651 and the second jaw 652 are closed to clamp and fix the area near the wire end of the wire bundle. When the first X-axis driving member 661 drives the first jaw 651 to move away from the second jaw 652 and the second X-axis driving member 662 drives the second jaw 652 to move away from the first jaw 651, the first jaw 651 and the second jaw 652 are opened to release the area near the wire end of the wire bundle. The first X-axis driving member 661 can be an electric push rod, a cylinder, a hydraulic cylinder or other driving assemblies. Similarly, the second X-axis driving member 662 can also be an electric push rod, a cylinder, a hydraulic cylinder or other driving assemblies.

[0058] Please refer to Figure 10 and Figure 11 , to limit the rotation angle range of the second jaw 652 and ensure the working stability of the wire end clamping mechanism 6, a limiting groove 641 is provided on the second fixing strip 64, and a part of the second jaw 652 is located in the limiting groove 641. In this embodiment, the second fixing strip 64 is located between the first fixing strip 63 and the substrate 61, and the limiting groove 641 communicating with the top surface and the bottom surface of the second fixing strip 64 is provided on the side of the second fixing strip 64 close to the first fixing strip 63. Optionally, the second jaw 652 is rotatably connected to the second fixing strip 64 through a rotating shaft, and the rotating shaft is located in the limiting groove 641.

[0059] A connecting block 642 is provided on the second fixing strip 64, and the second elastic member 62 is respectively connected to one end of the second jaw 652 and the connecting block 642 to drive the other end of the second jaw 652 to approach the first jaw 651. In this embodiment, the connecting block 642 is fixedly connected to the top of the second fixing strip 64 by screws. In other embodiments, the connecting block 642 and the second fixing strip 64 can be an integrally formed one-piece structure. Additionally, in other embodiments, torsion springs, springs, elastic sheets, spring washers, etc. can also be selected as the elastic members.

[0060] Please refer to Figure 8 andFigure 10 , specifically, the first fixing strip 63 is provided with a plurality of the first clamping jaws 651, the second fixing strip 64 is provided with a plurality of second clamping jaws 652, the plurality of the first clamping jaws 651 and the plurality of the second clamping jaws 652 are arranged in one-to-one correspondence, and the number of the second elastic members 62 is also a plurality and is arranged in one-to-one correspondence with the second clamping jaws 652. In this embodiment, the number of the first clamping jaws 651, the second clamping jaws 652, and the twisting component 4 is ten respectively. The elastic clamping and fixing structure composed of the first clamping jaws 651, the second clamping jaws 652, and the second elastic members 62 can stably clamp and fix the wire heads. When the first fixing strip 63 and the second fixing strip 64 slide towards each other, the wire heads of each wire bundle can be stably clamped by the corresponding elastic clamping and fixing structure, avoiding the phenomenon that individual wire heads are unstably clamped due to factors such as processing tolerances.

[0061] As a preferred embodiment, it further includes a guide plate 67 provided on the substrate 61. A guide groove 671 is provided on one side of the guide plate 67 close to the substrate 61, and the first fixing strip 63 and / or the second fixing strip 64 is located in the guide groove 671. The setting of the guide plate 67 can effectively protect the first fixing strip 63 and / or the second fixing strip 64, reducing the probability of the first fixing strip 63 and / or the second fixing strip 64 being impacted by foreign objects and contaminated by dust, which is beneficial to ensuring the working stability and structural stability of the wire head clamping mechanism 6.

[0062] The wire head clamping mechanism 6 further includes a first lifting drive member 681 provided on the fixing frame 5, and the substrate 61 is connected to the fixing frame 5 through the first lifting drive member 681. The first lifting drive member 681 can be an electric push rod, a cylinder, a hydraulic cylinder or other drive components. In this way, the first clamping jaws 651 and the second clamping jaws 652 can be lifted to avoid the wire heads of the horizontally conveyed wire bundles. It is easy to understand that in other embodiments, the first lifting drive member 681 may not be provided.

[0063] Please combine Figure 8 and Figure 9 , for the convenience of subsequent processing, optionally, the twisting device further includes a wire head bending mechanism 69. The wire head bending mechanism 69 includes a second lifting drive member 691 and a bending plate 692. The second lifting drive member 691 is provided on the side of the substrate 61 away from the first fixing strip 63, the second lifting drive member 691 is connected to the bending plate 692, and the second lifting drive member 691 can be an electric push rod, a cylinder, a hydraulic cylinder or other drive components. Preferably, a wire pressing groove 6921 is provided on the bending plate 692, and the wire pressing groove 6921 can prevent the wire heads of the wire bundles from shifting in the X-axis direction.

[0064] The working process of the present twisting device is briefly described as follows: after the thread end of the thread handle moves to the preset position, the first lifting drive member 681 drives the base plate 61 to descend, so that the thread end is located between the first clamping jaw 651 and the second clamping jaw 652, and the driving assembly drives the first clamping jaw 651 and the second clamping jaw 652 to close to clamp the rear area of the thread end; the second Y-axis drive member 32 drives the fixing plate 22 to approach the first clamping jaw 651, so that the thread end enters between the first claw 421 and the second claw 422, and then, The first Y-axis driving member 31 drives the push plate 23 to move toward the fixed plate 22, so that the end of the resistance member 44 near the fixed plate 22 extends into the rotating drum 41 and the concave conical surface contacts the matching conical surface 424, thereby compressing the first elastic member 43 and clamping the thread end with the X-shaped clamp 42. Then, the rotary driving member 11 drives the rotating drum 41 to rotate (in the process of rotating the rotating drum 41, the resistance member 44 will also rotate with the rotating drum 41 under the drive of the rotating drum 41), so that the thread end is twisted. Then, the first Y-axis driving member 31 drives the push plate 23 to move away from the fixed plate 22, so that the X-shaped clamp 42 releases the twisted thread end; the second Y-axis driving member 32 drives the bottom plate 21 to drive the fixed plate 22 to move in the direction away from the first clamp 651. Then, the second lifting drive member 691 drives the bending plate 692 to descend to bend the twisted wire end and reset it. Finally, the first lifting drive member 681 drives the base plate 61 to ascend to complete the entire wire twisting action.

[0065] To sum up, the wire twisting device provided by the present invention has a novel structure and a compact size. Compared with the existing clamping cylinder, the wire twisting assembly in the wire twisting device has a significantly reduced width in the X-axis direction required for its rotation, so that the wire twisting device with the same width size can carry a larger number of wire twisting assemblies, so that the wire twisting device can complete the wire twisting work of a larger number of wire handles at a time, which is beneficial to improving the production efficiency of the production line and reducing production costs.
