Description

Technical Field

[0001] This utility model relates to the field of coaxial cable manufacturing technology, and in particular to a coaxial cable swing support weaving mechanism. Background Technology

[0002] Currently, in the manufacturing of wire harnesses for new energy vehicles, 5G communications, and optical cameras, coaxial wire harnesses are typically manufactured by wrapping an inner insulating tubular layer around the inner copper core conductor, then wrapping a shielding braided layer around the inner insulating tubular layer, and finally wrapping an outer insulating tube around the braided layer. During the production process of stretching the braided layer, part of the outer insulating tube is cut off at one end of the wire harness, exposing part of the braided layer. The braided layer is mainly used to shield external electromagnetic fields and prevent interference with signals inside the conductor.

[0003] However, most manufacturers still use manual methods to stretch the braided layer during production. This is done manually using jigs, but often the braided layer cannot be fully stretched, leading to a higher electrical test failure rate. Furthermore, each jig is only suitable for one wire diameter, resulting in low adaptability, high time and labor costs, and low production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a coaxial swing support weaving mechanism, which addresses the shortcomings of the existing technology and aims to solve the technical problem that most manufacturers now use manual methods to open the coaxial weaving layer with fixtures, which is time-consuming and labor-intensive, resulting in low production efficiency and adaptability.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a coaxial swing bracing weaving mechanism, including a vertically upward-facing clamping member, a transverse driving member opposite to the clamping member, and a swing assembly above the transverse driving member. The swing assembly includes a shaft and a rotating cylinder sleeved on the front of the shaft and extending and retracting relative to it. A push-pull member for pushing back and forth is rotatably connected to the tail of the shaft. A rotating member and an eccentric member are respectively provided at the tail and front of the rotating cylinder. The eccentric member includes a front wheel and a rear wheel sequentially sleeved on the front of the rotating cylinder. An eccentric wheel is fixedly connected to the front of the front wheel, and an eccentric groove is provided at the center of the eccentric wheel. An eccentric block is provided at the front end of the rear wheel and extends into the front wheel at an incline. A movable block is engaged with the front of the front wheel, and an eccentric rod is fixedly connected to the front of the movable block. The rear wheel is fixedly connected to the shaft and movably connected to the rotating cylinder. The eccentric block passes through the front wheel and is inserted into the side end of the movable block. The eccentric rod passes through the eccentric groove and extends out, so that the eccentric block drives the eccentric rod to move and adjust within the eccentric groove.

[0006] Furthermore, the clamping component includes a fixed clamp and a positioning clamp coaxially arranged with the fixed clamp at the front and rear, and both the fixed clamp and the positioning clamp are connected to a drive cylinder.

[0007] Furthermore, the lateral drive component includes a slide rail, a slider slidably connected to the slide rail, and a drive component fixedly connected to the slider, with the swing assembly fixedly mounted above the slider.

[0008] Furthermore, a fixed seat is rotatably connected to the middle of the rotating cylinder, and a movable groove is provided on the side of the rotating cylinder near the front end of the fixed seat along the length direction. The rear wheel is fixedly connected to the axle through the movable groove.

[0009] Furthermore, a guide shaft connects the eccentric wheel, the front wheel, and the rear wheel.

[0010] Furthermore, a receiving groove is provided along the diameter on the front of the front wheel, and a T-shaped sleeve is installed in the receiving groove, with the movable block movably connected to the sleeve.

[0011] Furthermore, a notch for accommodating the eccentric block is provided at the side end of the accommodating groove of the eccentric wheel, so that the eccentric block can be inserted into the notch after passing through the front wheel.

[0012] Furthermore, the eccentric groove is located at the center of the eccentric wheel and extends symmetrically to both sides along the diameter.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: This utility model clamps the coaxial cable to be processed by setting a clamping component to ensure that the coaxial cable will not deviate during processing. The lateral drive component transports the swing assembly to a position closer to the clamping component, and makes the eccentric rod coaxial with the coaxial cable and extend into the braided layer. The push-pull component drives the shaft to move laterally and pushes the rear wheel, thereby driving the eccentric inclined block to extend and retract back and forth. The eccentric inclined block is inserted into one end of the movable block, so that the eccentric inclined block drives the movable block to move. The eccentric rod moves to the designated position in the eccentric groove. The rotating component is activated to drive the rotating cylinder to rotate, which synchronously drives the front wheel and the eccentric wheel to rotate, so that the eccentric rod rotates eccentrically, realizing the automatic swinging and opening of the braided layer of the coaxial cable. Automatic processing replaces manual operation, avoids the use of multiple sets of fixtures, reduces production costs and defect rates, improves production efficiency, and enhances the adaptability of use.

[0019] In order to better understand the above-mentioned objectives, technical solutions and advantages of this application, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings, and to understand in detail how to solve the problems raised in the background art.

[0020] like Figures 1 to 4As shown, a coaxial rocking braiding mechanism includes a vertically upward-facing wire clamping member 1, a transverse drive member 232 opposite to the wire clamping member 1, and a rocking assembly 3 positioned above the transverse drive member 232. The rocking assembly 3 includes a shaft 31 and a rotating cylinder 32 sleeved on the front of the shaft 31 and extending and retracting relative to it. A push-pull member 33 for pushing back and forth is rotatably connected to the tail of the shaft 31. A rotating member 34 and an eccentric member 35 are respectively provided at the tail and front of the rotating cylinder 32. The eccentric member 35 includes a front wheel 350 and a rear wheel 353 sequentially sleeved on the front of the rotating cylinder 32. An eccentric member is fixedly connected to the front of the front wheel 350. The wheel 354 has an eccentric groove 356 at its center. The rear wheel 353 has an eccentric block 357 that extends into the front wheel 350 at its front end. The front wheel 350 has a movable block 358 that is engaged with its front side. An eccentric rod 359 is fixedly connected to the front side of the movable block 358. The rear wheel 353 is fixedly connected to the axle 31 and movably connected to the rotating cylinder 32. The eccentric block 357 passes through the front wheel 350 and is inserted into the side end of the movable block 358. The eccentric rod 359 passes through the eccentric groove 356 and extends out, so that the eccentric block 357 drives the eccentric rod 359 to move and adjust within the eccentric groove 356.

[0021] Through the above scheme, the clamping member 1 can clamp the coaxial cable to be processed, ensuring that it will not deviate when processing the coaxial cable. The lateral drive member 232 transports the swing assembly 3 to a position closer to the clamping member 1, and makes the eccentric rod 359 coaxial with the coaxial cable and embedded in the braided layer. The push-pull member 33 drives the shaft rod 31 to move laterally and pushes the rear wheel 353, thereby driving the eccentric inclined block 357 to tilt and extend back and forth. The eccentric inclined block 357 is inserted into one side of the movable block 358, so that the eccentric inclined block 357 drives the movable block 358 to move. The eccentric rod 359 moves to the designated position in the eccentric groove 356. The rotating member 34 is activated to drive the rotating cylinder 32 to rotate, and simultaneously drives the front wheel 350 and the eccentric wheel 354 to rotate, so that the eccentric rod 359 rotates eccentrically, realizing the automatic swinging and opening of the braided layer of the coaxial cable. Automatic processing replaces manual operation, avoids the use and production of multiple sets of fixtures, reduces production costs and defect rates, improves production efficiency, and enhances the adaptability of the mechanism.

[0022] like Figure 1 and Figure 3 As shown, in this embodiment, the rotating component 34 consists of a timing belt, two timing pulleys (upper and lower), and a motor. The rotating cylinder 32 passes through the lower timing pulley and is fixedly connected. The rotating component 34 can drive the rotating cylinder 32 to rotate. The rotating component 34 is fixed above the slider 22.

[0023] like Figure 1 and Figure 2As shown, in one specific embodiment of the improvement, the wire clamping member 1 includes a fixed clamping claw 11 and a positioning clamping claw 12 arranged coaxially with the fixed clamping claw 11. Both the fixed clamping claw 11 and the positioning clamping claw 12 are connected to a drive cylinder 13.

[0024] Specifically, the clamping component 1 has a base plate for mounting to the equipment below it. The clamping component 1 is vertically set at the front end of the base plate. The clamping component 1 also includes a lifting drive cylinder fixed to the base plate. A fixed plate is installed at the output end of the lifting drive cylinder. A vertically upward positioning gripper 12 is installed on the side of the fixed plate. A horizontal plate facing the swing assembly 3 is vertically connected to the top of the fixed plate. The positioning gripper 12 is set on the horizontal plate. During actual processing, the lifting drive cylinder is activated and pushes the fixed gripper 11 and the positioning gripper 12 to the specified height. The two drive cylinders 13 are activated one after the other. The positioning gripper 12 performs a clamping action to achieve precise positioning for coaxial cable processing. Then, the fixed gripper 11 clamps the middle end of the coaxial cable to be processed. The positioning gripper 12 can ensure that the fixed gripper 11 will not deviate when clamping the wire harness to be processed. Finally, the positioning gripper 12 releases the coaxial cable to be processed. It is worth noting that the fixed gripper 11 has a long extension length, which increases the area of ​​the coaxial cable to be clamped, which facilitates subsequent processing.

[0025] like Figure 1 As shown, in one specific embodiment of the improvement, the lateral drive member 232 includes a slide rail 21, a slider 22 slidably connected to the slide rail 21, and a drive member 23 fixedly connected to the slider 22. The swing assembly 3 is fixedly installed above the slider 22.

[0026] Specifically, two vertical plates and a placement plate perpendicular to the vertical plates are installed above the rear end of the base plate. The horizontal drive component 232 is installed on the placement plate to ensure that the swing assembly 3 and the clamping component 1 can be set coaxially. During actual processing, the drive component 23 drives the slider 22 to move forward on the slide rail 21, transporting the swing assembly 3 to a position closer to the clamping component 1, so that the eccentric rod 359 is set on the same straight line as the coaxial line and is embedded in the braided layer. In addition, the push-pull component 33 is fixed on the slider 22. The push-pull component 33 is a horizontally moving sliding component. There is a connecting plate between the push-pull component 33 and the shaft 31. The shaft 31 and the connecting plate are rotatably connected by bearings. The connecting plate is installed at the output end of the push-pull component 33, so that the push-pull component 33 can drive the shaft 31 to extend and retract back and forth. At the same time, the shaft 31 can also rotate with the rotating cylinder 32.

[0027] like Figure 3 and Figure 4 As shown, in one specific embodiment of the improvement, a fixed seat 36 is rotatably connected to the middle of the rotating cylinder 32, and a movable groove (not shown) is provided on the side of the rotating cylinder 32 near the front end of the fixed seat 36 along the length direction. The rear wheel 353 is fixedly connected to the shaft 31 through the movable groove.

[0028] Specifically, a bearing is installed in the middle of the fixed seat 36, and the rotating cylinder 32 passes through the bearing to ensure the rotation and positioning of the rotating cylinder 32. The movable slot is set along the length of the rotating cylinder 32. There are two movable slots and they are symmetrically arranged. After the rear wheel 353 is fitted with the sleeve 352, it can move back and forth along the movable slot. In order to facilitate the installation of the shaft 31 and the rear wheel 353, based on the symmetrical arrangement of the two movable slots, a through hole with the same straight line can be opened on the shaft 31 and the rear wheel 353. During installation, it is only necessary to align the insert shaft with the through hole and insert it, which is convenient and quick. In actual production, the shaft 31 can drive the rear wheel 353 to move back and forth in the rotating cylinder 32, thereby driving the eccentric inclined block 357 to extend and retract obliquely.

[0029] like Figure 4 As shown, in one specific embodiment of the improvement, a guide shaft 37 is connected between the eccentric wheel 354, the front wheel 350 and the rear wheel 353.

[0030] Specifically, there are two guide shafts 37. The guide shafts 37 pass through the eccentric wheel 354, the front wheel 350 and the rear wheel 353. The front wheel 350 is fixedly connected to the rotating cylinder 32, and the eccentric wheel 354 is fixedly connected to the front wheel 350. On the one hand, this can ensure that the eccentric wheel 354, the front wheel 350 and the rear wheel 353 form an integrated structure for rotation and drive the shaft 31 to rotate, ensuring the stability of the structure. On the other hand, it can guide the movement of the rear wheel 353 to avoid collision with the rotating cylinder 32 and improve its service life.

[0031] like Figure 4 As shown, in one specific embodiment of the improvement, the front wheel 350 has a receiving groove 351 along the diameter on its front side, and a T-shaped sleeve 352 is installed in the receiving groove 351. The movable block 358 is movably connected to the sleeve 352.

[0032] Specifically, the sleeve 352 is fixedly connected to the front wheel 350. The sleeve 352 blocks one side of the receiving groove 351. The sleeve 352 and the movable block 358 can move after being sleeved together. When the eccentric inclined block 357 extends and retracts obliquely under the drive of the rear wheel 353, the movable block 358 can extend and retract along the sleeve 352, thereby driving the eccentric rod 359 to adjust its position.

[0033] like Figure 4 As shown, in one specific embodiment of the improvement, the eccentric wheel 354 is provided with a notch 355 at the side end of the receiving groove 351 for receiving the eccentric inclined block 357, so that the eccentric inclined block 357 can be inserted into the notch 355 after passing through the front wheel 350.

[0034] Specifically, the receiving groove 351 passes through both ends of the front wheel 350, which facilitates the installation of the sleeve 352 and allows the movable block 358 to extend along the receiving groove 351 to avoid jamming. The top surfaces of the front wheel 350, sleeve 352 and movable block 358 are coplanar. Both the front wheel 350 and movable block 358 are provided with inclined holes for receiving the eccentric inclined block 357. One end of the eccentric inclined block 357 is fixed on the rear wheel 353, and the other end of the eccentric inclined block 357 extends out from the notch 355 after passing through the inclined hole, so as to avoid the eccentric inclined block 357 being blocked when it extends or retracts.

[0035] like Figure 3 As shown, in one specific embodiment of the improvement, the eccentric groove 356 is disposed at the center of the eccentric wheel 354 and extends symmetrically to both sides along the diameter.

[0036] Specifically, the eccentric groove 356 is adapted to the eccentric rod 359. The eccentric groove 356 can provide the range of movement for the eccentric rod 359. When processing different coaxial lines, the eccentric rod 359 can be adjusted along the eccentric groove 356, thereby realizing the position adjustment of the eccentric rod 359 and ensuring the adaptability of the equipment.

[0037] Workflow: First, clamping component 1 clamps and fixes the coaxial cable to be processed. Drive cylinder 13 is activated, and positioning jaws 12 and fixing jaws 11 successively merge to clamp the coaxial cable. Then, positioning jaws 12 release the coaxial cable to prevent the fixing jaws 11 from shifting when clamping it. Next, lateral drive component 232 transports the swing assembly 3 above slider 22 to a position closer to clamping component 1, so that the eccentric rod 359 is coaxially aligned with the coaxial cable and embedded in the braided layer. Push-pull component 33 then initiates lateral push-pull mechanism 31 forward. The movement drives the rear wheel 353 forward, pushing the eccentric block 357 to move obliquely, so that the eccentric rod 359 is placed at the outer end of the eccentric groove 356. Finally, the rotating component 34 drives the rotating cylinder 32 to rotate, so that the shaft 31 and the front wheel 350 both rotate. The eccentric rod 359 rotates eccentrically for 5-10 seconds. After the processing is completed, the transverse drive component 232 retracts, the swing assembly 3 resets, and the fixed gripper 11 opens. The automated processing of a coaxial swing support braided layer is completed. This cycle can be repeated.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
