Description

Technical Field

[0001] This utility model relates to the technical field of machining, and in particular to a synchronous turning device for large-size guide post forgings. Background Technology

[0002] As the "mother machine" in the field of machining, the lathe is widely used for machining rotating parts such as shafts, discs, and sleeves. Its basic working principle is to hold the workpiece in a chuck and rotate it, while cutting is performed by a fixed tool on the tool post. In order to expand the functions of the lathe, various composite improvement schemes have emerged in the existing technology.

[0003] For example, Chinese utility model patent CN206464828U discloses a lathe. This lathe adds a grinding head fixture to a traditional tool holder and has a second motor to drive the grinding head to rotate, thereby enabling rough machining (turning) and finish machining (grinding) of workpieces to be completed on the same machine tool. This avoids the repeated clamping of workpieces between different devices, effectively improving processing efficiency and reducing surface quality damage caused by repeated positioning errors.

[0004] However, after in-depth analysis and practical experience, the applicant discovered that the existing lathe structure is primarily designed for shaft parts of conventional sizes. When used to machine large-sized, high-length-to-diameter guide post forgings, its structure exhibits significant limitations and deficiencies. Specifically, the workpiece support on this type of lathe typically relies solely on the chuck at the head end and the tailstock at the tail end, lacking necessary intermediate guiding and support mechanisms. Large guide post forgings are extremely heavy, and when supported only at both ends, they experience significant sagging deformation (static deformation) due to their own weight. When the workpiece is driven to rotate by the chuck, this deformation transforms into periodic radial runout, severely affecting machining accuracy (such as straightness and cylindricity), leading to part scrap, and also causing severe vibration and chatter, making the cutting process unstable. Furthermore, the enormous overhang length also poses a safety hazard when the workpiece rotates. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a synchronous turning device for large-size guide post forging blanks.

[0006] This utility model discloses a synchronous turning device for large-size guide post forging blanks, including a worktable and a controller. The worktable is equipped with the controller and also includes a rotating component, a fixing component, a turning component, and a support component. The rotating component, fixing component, turning component, and support component are respectively arranged on the top of the worktable. The rotating component is used to clamp and rotate the guide post forging blank. The fixing component cooperates with the rotating component to tighten the other end of the guide post forging blank. The support component is used to support and guide the bottom end of the guide post forging blank. The turning component is used to turn the outer wall of the guide post forging blank. In use, the guide post forging blank is temporarily supported by the support component. Then, the rotating component is operated to clamp one end of the guide post forging blank, and the fixing component fixes the other end of the guide post forging blank. The controller causes the rotating component to drive the guide post forging blank to rotate, and the support component stabilizes the rotation of the guide post forging blank. The turning component is operated to turn the outer wall of the rotating guide post forging blank, thereby improving the machining accuracy.

[0007] Preferably, the rotating assembly includes a base and an electro-hydraulic chuck. The base is located at the top of the worktable, and the electro-hydraulic chuck is mounted on the base. The electro-hydraulic chuck is connected to the controller. First, the controller operates the electro-hydraulic chuck to clamp one end of the guide column forging blank. Then, the electro-hydraulic chuck drives the guide column forging blank to rotate, thereby improving processing efficiency.

[0008] Preferably, the fixing assembly includes a fixed base, a first servo electric cylinder, a first moving plate, and a fixing head. The fixed base is provided at the top of the worktable, and the first servo electric cylinder is installed on the fixed base. The moving end of the first servo electric cylinder is provided with a first moving plate, and the fixing head is installed on the first moving plate. The first servo electric cylinder is extended by the controller, so that the first moving plate drives the fixing head to press against the other end of the guide column forging blank, thereby suspending the guide column forging blank in the air, so that the electric hydraulic chuck can drive the guide column forging blank to rotate.

[0009] Preferably, the support assembly includes a second servo electric cylinder, a lifting frame, a mounting frame, guide rollers, and a first optical bar. The second servo electric cylinder is located at the top of the worktable. The lifting frame is located at the top moving end of the second servo electric cylinder. Two sets of mounting frames are located at the top of the lifting frame. A set of guide rollers is rotatably mounted inside each set of mounting frames. A first optical bar is located at the bottom of the guide rollers and is slidably connected to the worktable. The operator operates the second servo electric cylinder to extend through the controller, thereby causing the lifting frame to drive the two sets of guide rollers to contact the bottom of the guide column forging blank. When the guide column forging blank rotates, the guide rollers rotate adaptively to improve the stability of the rotation of the guide column forging blank.

[0010] Preferably, the turning assembly includes side plates, guide rods, lead screws, a first motor, a moving base, a third servo electric cylinder, a third moving plate, a turning head, and a support. A pair of side plates are respectively provided on the front and rear ends of the worktable. A set of lead screws is rotatably mounted between each pair of side plates, and a set of guide rods is fixedly mounted between each pair of side plates. Two sets of first motors are respectively mounted on a set of side plates, and the output end of each set of first motors is connected to one end of a set of lead screws. Two sets of moving bases are respectively threadedly connected to a set of lead screws and slidably connected to a set of guide rods. A set of supports is mounted on the top of the two sets of moving bases, and a set of third servo electric cylinders is provided at the front and rear ends of the supports. The cylinder has two sets of No. 3 servo electric cylinders, each with a No. 3 moving plate at its moving end. Each of the two sets of No. 3 moving plates has a No. 2 motor, and the output end of each No. 2 motor has a turning head. After the guide post forging is installed, the electro-hydraulic chuck rotates it, the two sets of No. 3 servo electric cylinders extend, and the No. 2 motor is started, causing the two sets of turning heads to rotate rapidly. This causes the rapidly rotating turning heads to contact the outer wall of the guide post forging for grinding. The No. 1 motor is operated, causing the moving seat to move the two sets of turning heads horizontally under the cooperation of the guide rod and lead screw, thus achieving synchronous turning of the guide post forging and improving processing efficiency.

[0011] Preferably, it also includes a second optical bar, which is provided on the first moving plate and is slidably connected to the fixed base; the first servo electric cylinder drives the top fixing head to move stably under the guidance of the second optical bar, thereby improving stability.

[0012] Preferably, it also includes a third optical bar, which is installed on a third movable plate and is slidably connected to the bracket; the third servo electric cylinder drives the third movable plate to move stably under the guidance of the third optical bar, thereby improving stability.
