Description

Technical Field

[0001] This utility model relates to the field of fiber winding technology, specifically a fiber winding mechanism with strong adaptability and high precision. Background Technology

[0002] Fiber winding technology is one of the core manufacturing processes for high-performance composite material products, and it is widely used in aerospace (such as pressure vessels and pipelines), new energy (such as wind turbine blades), rail transportation (such as high-speed rail bogie components) and other fields.

[0003] Traditional fiber winding mechanisms typically have the following problems:

[0004] Poor adaptability: It usually adopts the "fixed guide rail + single axis drive" structure. When the core mold size (diameter, length, curved surface shape) changes, it is necessary to readjust or even replace the special tooling, which results in long changeover time and low efficiency.

[0005] Insufficient precision due to low levelness: When the mandrel is fixed, especially for mandrels with a large length, the levelness of the mandrel (there is a height difference between the left and right ends of the mandrel) is low. At this time, the gap error between the left and right ends of the winding fiber can reach more than 0.3mm. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a fiber winding mechanism with high adaptability and flexibility, and high precision that can verify the levelness of the mandrel.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A highly adaptable and precise fiber winding mechanism includes a first robotic arm fixed vertically on the left side, a second robotic arm slidably mounted vertically on the right side of the fixed robotic arm, and a winding drive and positioning device installed between the first robotic arm and the second robotic arm. The winding drive and positioning device can fix a core mold of unlimited length.

[0009] A support device is installed directly below the winding drive and positioning device; the support device includes a bottom bracket fixedly installed on robotic arm one or robotic arm two and two support rods rotatably installed above the bottom bracket, wherein the two support rods can support the left or right end of the core mold; the surface of the front support rod is engraved with wavy rolling indication lines.

[0010] By adopting the above scheme, since the distance between robotic arm one and robotic arm two is adjustable, it can accommodate mandrels of different diameters and lengths, making it more adaptable and flexible in application. To ensure the stability of the mandrel during rotation, both ends of the mandrel are supported on two support rollers, making the mandrel more stable and reliable during rotation and winding. To easily indicate the levelness of the mandrel after fixing, the operator can observe the rolling indicator line on the surface of the support roller. If the rolling indicator line is in a wavy dynamic state when the mandrel rotates, both ends of the mandrel are in contact with the support roller, indicating a higher levelness of the mandrel, and thus higher accuracy after winding. Conversely, if the rolling indicator line of one side is static, the levelness of the mandrel is lower, and the mandrel should be quickly fixed.

[0011] In a preferred embodiment of a fiber winding mechanism that is highly adaptable and precise, the front support rod is a different color from the rear support rod, and the front support rod is a light color; the front support rod is a different color from the rolling indicator line, and the rolling indicator line is a dark color.

[0012] By adopting the above scheme, in order to facilitate staff to clearly observe the rolling indicator line, the front support rod and the rolling indicator line are colored with a large color difference, so that staff can easily observe the changes in the rolling indicator line and thus identify whether the front support rod is rotating.

[0013] As a preferred embodiment of a fiber winding mechanism with strong adaptability and high precision, it also includes a guide rail 1 horizontally fixed above the second robotic arm and a guide rail 2 horizontally fixed below the second robotic arm, with the top and bottom ends of the second robotic arm slidably mounted on the guide rail 1 and the guide rail 2, respectively.

[0014] By adopting the above scheme, in order to facilitate the adjustment of the distance between robotic arm one and robotic arm two, robotic arm two can slide along guide rail one, guide rail two and laterally to change the distance between robotic arm one and robotic arm two, thereby adapting to core molds of different lengths.

[0015] As a preferred embodiment of a fiber winding mechanism with high adaptability and precision, a lead screw with a turntable is installed through the top of the second robotic arm, wherein the head of the lead screw can abut against the guide rail and fix the second robotic arm.

[0016] By adopting the above scheme, in order to facilitate the fixing of the second robotic arm after adjustment, the first rotating turntable drives the first lead screw to abut against the side of the first guide rail, thereby pressing the second robotic arm tightly.

[0017] As a preferred embodiment of a fiber winding mechanism with strong adaptability and high precision, the winding drive and positioning device includes a drive part fixedly installed on a robotic arm one and a positioning part fixedly installed on a robotic arm two, wherein the drive part and the positioning part are concentrically opposite each other.

[0018] The drive unit includes a motor fixed on the left side of the robotic arm and a three-jaw chuck located on the right side of the robotic arm and concentrically connected to the motor.

[0019] The positioning section includes a lead screw 2 that runs horizontally through the second robotic arm, a turntable 2 that is concentrically connected to the right end of the lead screw 2, and a top rod that is concentrically connected to the left end of the lead screw 2 via a bearing.

[0020] By adopting the above scheme, in order to facilitate the fixing of the core mold, the left end of the core mold is fixed by a three-jaw chuck and the right end of the core mold is fixed by a push rod, thereby adapting to core molds of different diameters. The core mold is rotated as a whole by a motor, thereby completing the winding and shaping of the fiber on the core mold.

[0021] The beneficial effects of this utility model are:

[0022] 1. High adaptability and flexibility: It can install core molds of different diameters and lengths, making it more adaptable and flexible in application.

[0023] 2. High winding precision: Before the mandrel is wound, the levelness of the mandrel can be identified by observing the state of the rolling indicator line, thus ensuring the precision of fiber winding. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1 to 3 As shown, a highly adaptable and precise fiber winding mechanism is provided for winding and molding high-performance fibers. Specifically, it includes a robotic arm 1 vertically fixed to the left, a robotic arm 2 vertically slidably mounted to the right of the fixed robotic arm, and a winding drive and positioning device simultaneously installed between robotic arms 11 and 2. The winding drive and positioning device can fix a mandrel 10 of unlimited length. Since the distance between robotic arms 11 and 2 is adjustable, it can accommodate mandrels 10 of different diameters and lengths, making it more adaptable and flexible in application. To ensure the stability of the mandrel 10 during rotation, both ends of the mandrel 10 are supported by two supporting rollers 902, making the mandrel 10 more stable and reliable during rotational winding.

[0036] like Figures 4 to 8As shown, a support device 9 is installed directly below the winding drive and positioning device. The support device 9 includes a bottom bracket 901 fixedly mounted on either robotic arm 1 or robotic arm 2, and two support rods 902 rotatably mounted above the bottom bracket 901. The two support rods 902 can support the left or right end of the core mold 10. A wavy rolling indicator line 903 is engraved on the surface of the front support rod 902. To facilitate the indication of the levelness of the core mold 10 after fixing, the operator can observe the rolling indicator line 903 on the surface of the front support rod 902. If the rolling indicator line 903 is in a wavy dynamic state when the core mold 10 is rotating, then both ends of the core mold 10 are in contact with the support rod 902. At this time, the levelness of the core mold 10 is high, and the accuracy of the core mold 10 after winding will be higher. Conversely, if the rolling indicator line 903 of one side is in a static state, the levelness of the core mold 10 is low, and the fixed state of the core mold 10 should be quickly checked.

[0037] like Figure 8 As shown, the supporting rod 902 at the front is a different color from the supporting rod 902 at the rear, and the front supporting rod 902 is a lighter color, such as white, while the rear supporting rod 902 is green; continuing as... Figure 8 As shown, the supporting rod 902 at the front is a different color from the rolling indicator line 903, and the rolling indicator line 903 is a dark color, such as black. To facilitate clear observation of the rolling indicator line 903 by the staff, the supporting rod 902 and the rolling indicator line 903 are colored with a significant difference, making it easier for staff to observe changes in the rolling indicator line 903 and thus identify whether the supporting rod 902 is rotating.

[0038] like Figures 1 to 2 As shown, it also includes a guide rail 3 horizontally fixed above the robotic arm 2 and a guide rail 4 horizontally fixed below the robotic arm 2. The top and bottom ends of the robotic arm 2 are slidably mounted on the guide rail 3 and guide rail 4, respectively. To facilitate adjustment of the distance between the robotic arm 1 and the robotic arm 2, the robotic arm 2 can slide along the guide rail 3, guide rail 4, and horizontally to change the distance between the robotic arm 1 and the robotic arm 2, thereby adapting to core molds 10 of different lengths.

[0039] Continue as Figures 1 to 2 As shown, a lead screw 5 with a turntable 6 is installed through the top of the robotic arm 2. The head of the lead screw 5 can abut against the guide rail 3 and fix the robotic arm 2. To facilitate the fixing of the robotic arm 2 after adjustment, the turntable 6 is rotated to drive the lead screw 5 to abut against the side of the guide rail 3, thereby pressing the robotic arm 2 tightly.

[0040] like Figures 4 to 7As shown, the winding drive and positioning device includes a drive part 7 fixedly mounted on robotic arm 1 and a positioning part 8 fixedly mounted on robotic arm 2, wherein the drive part 7 and the positioning part 8 are concentrically opposite each other; the drive part 7 includes a motor 701 fixed on the left side of robotic arm 1 and a three-jaw chuck 702 located on the right side of robotic arm 1 and concentrically connected to the motor 701; the positioning part 8 includes a lead screw 801 that extends laterally through robotic arm 2, a turntable 802 concentrically connected to the right end of lead screw 801, and a push rod 804 concentrically connected to the left end of lead screw 801 via a bearing 803; wherein the rod head of the push rod 804 is frustum-shaped or conical. In order to facilitate the fixing of the mandrel 10, the left end of the mandrel 10 is fixed by the three-jaw chuck 702 and the right end of the mandrel 10 is fixed by the push rod 804, thereby adapting to mandrels 10 of different diameters, and the motor 701 drives the mandrel 10 to rotate as a whole, thereby completing the winding and shaping of the fiber on the mandrel 10.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
