Abstract
Description
Technical Field
[0001] This utility model relates to the field of lathe technology, specifically to a semi-automatic winding lathe with a bend. Background Technology
[0002] In the manufacturing of industrial electrical systems, HVAC ducts, and automotive parts, elbow-type irregularly shaped parts often require the winding of coils, insulating tape, or other functional wires to achieve purposes such as electromagnetic induction, thermal insulation, or structural reinforcement. Traditional winding operations mostly rely on manual operation or processing with fixed templates and semi-automatic equipment.
[0003] Existing elbow winding equipment generally adopts a structure of fixed bracket + rotary drive shaft + passive conductor mechanism. The elbow workpiece is manually installed in a special fixture on the equipment, and then the winding device rotates around the workpiece to complete the winding. However, this method has obvious adaptation problems and efficiency bottlenecks when dealing with elbows with large curvature changes, irregular pipe diameters, and complex spatial structures.
[0004] Traditional fixtures have strong rigidity and limited adjustability, often only suitable for single-size or specific types of elbows. Tooling changes are cumbersome and lack versatility. Secondly, they lack high-degree-of-freedom spatial adjustment and posture control capabilities, making it impossible to ensure that the wire always fits snugly along the workpiece surface during winding, resulting in poor winding accuracy, uneven wire stacking, and large fluctuations in finished product quality. In addition, most existing equipment lacks effective tension control mechanisms and real-time winding path adjustment functions, making it highly dependent on the operator's skills, with low automation and limited production efficiency.
[0005] Therefore, there is an urgent need for a semi-automatic winding equipment that can adapt to various types of elbow structures, has spatial movable clamping capability and multi-axis collaborative winding function, so as to improve the adaptability, automation level and winding accuracy of winding processing of elbow-type irregular parts. Utility Model Content
[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0007] Therefore, the technical solution adopted by this utility model is as follows: a semi-automatic winding lathe for elbows, comprising: a winding base, a servo robotic arm, a tooling fixture, and a winding assembly; wherein, the servo robotic arm is mounted on the winding base, and its end is provided with a tooling fixture for clamping elbow-type workpieces; the winding assembly is mounted on the winding base and includes a shaft frame, a winding ring seat, and a drive motor, and the winding assembly is used to realize the automatic winding of wire onto the elbow workpiece.
[0008] Specifically, a servo robotic arm drives the tooling fixture to perform multi-axis posture adjustments, ensuring the elbow remains within the effective winding area to accommodate different workpiece sizes and shapes. Simultaneously, the winding ring seat rotates at a uniform speed under the drive motor, working with guide wheels and wire rollers to release and guide the wire, thus enabling winding operations for workpieces with complex structures. This structure possesses advantages such as strong adaptability, precise control, and uniform winding.
[0009] In a preferred example, the servo robotic arm is a multi-joint structure with at least six rotational degrees of freedom, mounted on a winding base, and can flexibly adjust the position and orientation of the tooling fixture in three-dimensional space; its end is connected to the tooling fixture through a shaft plate crossbeam, the shaft plate crossbeam including a geared motor and a transverse support bar, and the tooling fixture is slidably disposed on the surface of the crossbeam.

[0012] Specifically, the structure uses the elastic combination of the rolling groove and the clamping ear to provide stable limiting support for the winding seat during rotation, avoiding shaking or positional deviation during winding, and improving the stability and repeatability of the winding process.
[0013] In a preferred embodiment, the winding seat is equipped with multiple guide rollers and wire rollers. The wire rollers are used to store the wire to be wound, and the guide rollers are used to guide the wire exit path and control the winding angle. The winding seat is fixed to the output shaft of the drive motor to achieve continuous rotation during the winding process.
[0014] Specifically, the wire is evenly released under the rotational drive of the ring seat, and the winding angle and path are effectively controlled by the guide wheel, so that the wire is continuously and uniformly distributed along the curved surface of the workpiece, improving the density and neatness of the winding.
[0015] In a preferred example, the outer wall of the ring seat is provided with a notch to form a local elastic opening, so that the tooling fixture can pass smoothly through the ring area, realizing convenient clamping and disassembly of the bent workpiece;
[0016] Specifically, this structure improves loading and unloading efficiency, avoids tooling interference, and helps shorten cycle time to meet continuous operation requirements.
[0017] In a preferred example, the surface of the winding base is provided with a control panel, which is electrically connected to a servo robotic arm, a drive motor and a wire tension adjustment module to realize automatic coordinated control of the various systems;
[0018] Specifically, operators can set winding parameters, running path, tension range, etc. through the control panel to realize the automatic start, operation and termination of the whole machine, reduce the intensity of operation and improve the intelligence and safety of system operation.
[0019] In summary, this utility model, through the collaborative design of a multi-degree-of-freedom servo robotic arm and a rotary winding assembly, combined with a modular tooling structure and an automatic control unit, achieves efficient, stable, and precise winding of various specifications of irregularly shaped bent workpieces, and has good industrial application value and promotion prospects.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0031] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0032] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a semi-automatic winding lathe with a bent head.
[0033] Combination Figures 1-4 As shown, this utility model provides a semi-automatic winding lathe for bends, including a winding base 100, a servo robotic arm 110, a tooling fixture 120 disposed at the end of the servo robotic arm 110, and a winding assembly 200 disposed on the winding base 100. The semi-automatic winding lathe for bends is suitable for high-precision, automated wire winding operations on bends with irregular shapes.
[0034] Specifically, the servo robotic arm 110 is a multi-degree-of-freedom, multi-joint structure with at least six rotational degrees of freedom, and is mounted on the winding base 100. The end of the servo robotic arm 110 is connected to the tooling fixture 120 via a shaft plate crossbeam 111. The shaft plate crossbeam 111 includes a geared motor and a crossbar fixed to the end of the geared motor. The tooling fixture 120 is slidably mounted on the surface of the crossbar. Through a servo control system, the servo robotic arm 110 can drive the tooling fixture 120 to clamp the bent workpiece and perform three-dimensional spatial motion adjustments to adapt to the winding requirements of bent workpieces of different specifications and postures.
[0035] Specifically, the servo robotic arm 110 is a multi-joint structure with at least six rotational degrees of freedom. It is mounted on the winding base 100, and its end is connected to the tooling fixture 120 through the shaft plate crossbeam 111. It is used to realize precise adjustment of spatial three-dimensional position and attitude control. The servo robotic arm 110 integrates a drive motor, encoder and control signal interface to receive control commands and realize high-precision winding path guidance operation of the tooling fixture 120.
[0036] The winding assembly 200 includes a shaft frame 210, a winding ring holder 220, and a drive motor 230. The drive motor 230 is fixedly mounted on the surface of the winding base 100, and its output end is connected to the winding ring holder 220 to drive the winding ring holder 220 to rotate around the bend held by the tooling. The winding assembly 200 is also provided with multiple guide wheels 240 and wire rollers 221. The guide wheels 240 are disposed on the surface of the shaft frame 210 to guide the wire path; the wire rollers 221 are disposed on the winding ring holder 220 to store the wire and release it during the winding process.
[0037] The shaft bracket 210 is mounted on the winding base 100, and its surface has a rolling groove 211 for accommodating and limiting the rotation of the outer edge of the winding ring seat 220. A clamping lug 212 is movably mounted on one end of the shaft bracket 210, and a torsion spring structure is provided at the connection between the clamping lug 212 and the shaft bracket 210 for applying an elastic clamping force to the winding ring seat 220, thereby achieving stable support and guidance during the winding process.
[0038] Furthermore, to improve the convenience of the fixture entering and exiting the winding area, a notch 222 is provided on the side wall of the winding seat 220. The notch 222 allows the winding seat 220 to have local elastic deformation capability within a certain range, which facilitates the tooling fixture 120 to be smoothly inserted into and removed from the winding structure before and after winding, thereby improving work efficiency and mechanical coordination.
[0039] During use, after the workpiece bend is clamped by the tooling fixture 120, the servo robotic arm 110 drives it to move into the winding seat 220, aligning it with the rolling groove 211 and the clamping ear 212 structure to form a stable positioning; the drive motor 230 starts, driving the winding seat 220 to rotate continuously, and the wire wound on the surface of the wire roller 221 is gradually released along the path of the guide wheel 240 during the rotation, winding onto the outer surface of the bend; during the winding process, the tension of the wire is adjusted by the tension control module, and the control panel realizes the automated and coordinated operation of various parts of the system to ensure that the winding is tight, uniform and stable.
[0040] In terms of control, the winding base 100 is equipped with a control panel for controlling the operating status of the servo robotic arm 110, the drive motor 230 and the wire tension adjustment module, so as to realize automatic control of the entire process of the equipment.
[0041] Through the above structural configuration and action coordination, this utility model effectively solves the problems of poor adaptability, complex operation and uneven winding of traditional elbow winding equipment, and significantly improves the efficiency and accuracy of automated winding of elbow-type irregular parts.
[0042] Working principle and usage process of this utility model:
[0043] This utility model's semi-automatic bending lathe completes the automatic winding operation of irregularly shaped bending parts through the coordinated action of a servo robotic arm and a rotary winding mechanism. Its working principle is mainly as follows:
[0044] The servo robotic arm 110 is responsible for clamping the elbow and performing multi-degree-of-freedom motion to ensure that the elbow remains in the winding area during the winding process and adjusts its posture accordingly to achieve close contact with the winding; the tooling fixture 120 is connected to the end of the robotic arm and can slide within a limited range in conjunction with the shaft plate crossbeam 111 to adapt to the positioning requirements of elbows of different specifications.
[0045] The winding assembly 200 is driven by the drive motor 230 to rotate the winding seat 220, which, together with the wire roller 221 and guide wheel 240 on the ring, guides and releases the wire. The wire on the surface of the wire roller 221 is gradually released during the rolling motion of the winding seat 220 and wound onto the elbow surface of the tooling fixture 120.
[0046] The winding seat 220 is clamped into the rolling groove 211, and the clamping lug 212 and the torsion spring mechanism realize the elastic limit of the winding seat 220 to ensure the stability of the winding process.
[0047] The 222 notch structure gives the ring seat local elasticity, allowing the clamp to move in and out smoothly, which is beneficial for loading and unloading. The entire system achieves automated linkage control through the control panel, and works with the tension module to complete tension adjustment and process stabilization.
