DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described in connection with the drawings in the embodiments of the utility model. EMBODIMENT

[0018] Please refer to Figures 1-4 The utility model provides the following technical scheme: a distance changing wire clamp, including support base plate 100, the back surface fixed mounting of support base plate 100 has first connecting plate 110, the top fixed mounting of first connecting plate 110 has support seat 120, the top installation of support seat 120 has mounting box 200, one end of mounting box 200 is installed with distance changing air cylinder 210, and distance changing air cylinder 210 is connected with upper pressing plate 400 and lower pressing plate 500 respectively through opening and closing mechanism 300, and a plurality of upper clamping jaws 410 and a plurality of lower clamping jaws 510 are clamped and connected between upper pressing plate 400 and lower pressing plate 500, and the hinged seat of position opposite upper clamping jaw 410 and lower clamping jaw 510 hinged seat is staggered, and the hinged seat of a plurality of upper clamping jaws 410 and lower clamping jaws 510 is connected with rotating shaft 600, and both ends of rotating shaft 600 are all sleeved with rotating shaft support plate 610, and one side of rotating shaft support plate 610 is fixedly connected with the front surface of support base plate 100, and the front surface of support base plate 100 is also installed with clamping jaw distance changing mechanism 700 that drives adjacent upper clamping jaw 410 and lower clamping jaw 510 to slide in the axial direction of rotating shaft 600 and realizes distance changing.

[0019] Specifically, the support base plate 100 can be fixedly installed with the terminal crimping production equipment. When the terminal wires need to be clamped and the distance needs to be changed, the distance changing cylinder 210 starts to work. The extension and retraction of the distance changing cylinder 210 is transmitted to the upper pressing plate 400 and the lower pressing plate 500 through the opening and closing mechanism 300. The upper pressing plate 400 and the lower pressing plate 500 are close to each other, which drives the plurality of upper clamping jaws 410 and the plurality of lower clamping jaws 510 to close, thereby clamping the plurality of terminal wires.

[0020] Then, according to the arrangement and distance of the crimping jaws, the adjacent upper clamping jaws 410 and lower clamping jaws 510 are driven to slide axially on the rotating shaft 600 by the clamping jaw distance changing mechanism 700, so as to accurately adjust the distance between the adjacent clamping jaws, so that the terminal wires can be aligned with the corresponding crimping jaws, and the equidistant arrangement and clamping operation of the plurality of terminal wires are realized, thereby ensuring that each crimping jaw can accurately correspond to a terminal wire for crimping, and improving the production efficiency and product quality.

[0021] In the embodiment, the opening and closing mechanism 300 includes a cylinder joint 310 connected with the extension end of the distance changing cylinder 210. The cylinder joint 310 is rotatably connected with an upper swing arm 320 and a lower swing arm 330 through a pin in a U-shaped groove 311. The upper swing arm 320 and the lower swing arm 330 are rotatably connected with an upper cam arm 340 and a lower cam arm 350 through pins. The upper cam arm 340 and the lower cam arm 350 are connected with each other through a tooth groove. The upper cam arm 340 and the lower cam arm 350 are fixedly connected with the upper pressing plate 400 and the lower pressing plate 500 through the installation box 200.

[0022] Specifically, when the terminal wires need to be clamped, the extension end of the distance changing cylinder 210 is extended and retracted, so that the cylinder joint 310 drives the upper swing arm 320 and the lower swing arm 330 to swing. The swinging upper swing arm 320 and the lower swing arm 330 drive the upper cam arm 340 and the lower cam arm 350 to rotate. The upper cam arm 340 and the lower cam arm 350 are connected with each other through the tooth groove, so that the upper swing arm 320 and the lower swing arm 330 can drive the upper pressing plate 400 and the lower pressing plate 500 to be closed synchronously, thereby enabling the upper clamping jaws 410 and the lower clamping jaws 510 at the corresponding positions to clamp the terminal wires at the corresponding positions.

[0023] In the embodiment, the installation box 200 is connected with a stop lever 220 at the middle part. The stop lever 220 is located on one side of the tooth groove of the upper cam arm 340 and the lower cam arm 350.

[0024] Specifically, the stop lever 220 can prevent the tooth groove of the upper cam arm 340 and the lower cam arm 350 from being excessively offset when the upper cam arm 340 and the lower cam arm 350 are synchronously rotated, thereby ensuring the accuracy and stability of the movement of the upper cam arm 340 and the lower cam arm 350.

[0025] In the embodiment, the bottom of the upper pressing plate 400 and the top of the lower pressing plate 500 are provided with arc-shaped grooves 800, which are respectively clamped and connected with the arc-shaped hook heads 810 provided at one end of the upper clamping jaw 410 and the lower clamping jaw 510.

[0026] Specifically, when clamping the terminal wires, the upper pressing plate 400 and the lower pressing plate 500 are close to each other, and the arc-shaped grooves 800 and the arc-shaped hook heads 810 are clamped and connected, so as to drive the upper clamping jaw 410 and the lower clamping jaw 510 to close, thereby stably clamping the terminal wires; when the terminal wires need to be loosened, the upper pressing plate 400 and the lower pressing plate 500 are reversely moved, and the upper clamping jaw 410 and the lower clamping jaw 510 are opened, thereby ensuring the accuracy and stability of the clamping and loosening operations of the terminal wires in the production process.

[0027] In the embodiment, the clamping jaw distance changing mechanism 700 includes a plurality of second connecting plates 710 located at the bottom of the upper clamping jaw 410 and the lower clamping jaw 510. One end of the second connecting plate 710 is fixedly connected with the upper clamping jaw 410 or the lower clamping jaw 510 through a fixed pin. The sliding groove on the surface of the second connecting plate 710 is slidably connected with the adjacent upper clamping jaw 410 or the adjacent lower clamping jaw 510 through a connecting pin. The bottom of the lower clamping jaw 510 at the end is connected with a telescopic air cylinder 730 through a connecting seat 720. The middle part of the telescopic air cylinder 730 is fixedly connected with the front surface of the supporting bottom plate 100 through an air cylinder mounting plate 740.

[0028] Specifically, when the clamped terminal wires need to be arranged at equal distances, the telescopic air cylinder 730 is extended and contracted to drive one of the lower clamping jaws 510 to move. Since the adjacent upper clamping jaws 410 and the lower clamping jaws 510 are connected through the second connecting plates 710, the movement of the lower clamping jaw 510 at the end is transmitted to the adjacent clamping jaws through the sliding groove on the surface of the second connecting plate 710 and the connecting pin, so that the adjacent upper clamping jaws 410 and the lower clamping jaws 510 slide in the axial direction of the rotating shaft 600, thereby accurately adjusting the distance between the adjacent clamping jaws, achieving the equal-distance arrangement and clamping operation of the terminal wires, and ensuring that the terminal wires can be aligned with the corresponding twisting claws, meeting the requirement that multiple twisting claws simultaneously twist multiple terminal wires in the production process, and improving the production efficiency and product quality.
