Description
Technical Field
[0001] This utility model relates to the field of machining center technology, and in particular to a three-line rail vertical machining center with a rotatable worktable. Background Technology
[0002] In the field of machining, vertical machining centers are widely used in milling, drilling, boring, and other machining processes on various workpieces due to their high efficiency and precision. However, traditional vertical machining centers often have significant limitations when machining longer workpieces. The worktables of traditional vertical machining centers are mostly fixed or can only move in one direction, lacking rotation capabilities. When machining both ends of a long workpiece, if one end is inside the machining center while the other end is exposed, switching to machining the other end requires the operator to spend a significant amount of time disassembling and reclamping the workpiece, making the operation cumbersome and time-consuming. Utility Model Content
[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a three-line rail vertical machining center with a rotatable worktable, which solves the problem that when machining long workpieces, operators need to spend a lot of time disassembling and re-clamping the workpieces, which is cumbersome and time-consuming.
[0004] This utility model also provides a three-line rail vertical machining center with the above-mentioned rotatable worktable, comprising: a machining center body, a motor 1 fixedly connected to the outer surface of the machining center body, a lead screw 1 fixedly connected to the output end of the motor 1, a movable frame threadedly connected to the outer surface of the lead screw 1, a movable table fixedly connected to one end of the movable frame, a motor 2 fixedly connected inside the movable table, a gear 1 fixedly connected to the output end of the motor 2, a gear 2 meshing with the outer surface of the gear 1, a rotating rod fixedly connected to the inner wall of the gear 2, a worktable fixedly connected to the upper end of the rotating rod, a sprocket 1 fixedly connected to the outer surface of the lead screw 1, a chain meshing with the outer surface of the sprocket 1, a sprocket 2 meshing with the inner wall of the chain, a lead screw 2 fixedly connected to the inner wall of the sprocket 2, a baffle threadedly connected to the outer surface of the lead screw 2, and the inner wall of the baffle fitting against the machining center body.
[0005] Preferably, the end of the lead screw away from the motor is rotatably connected to a protective cover, and the two ends of the lead screw are rotatably connected to the machining center body and the protective cover, respectively. The protective cover protects the lead screw or mechanical transmission parts and extends the service life of the equipment.
[0006] Preferably, the outer surface of the protective cover is fixedly connected to the main body of the machining center, and the positions of lead screw one and lead screw two are located inside the protective cover. The rotation directions of lead screw one and lead screw two are opposite. The design of opposite rotation directions of the lead screws can realize bidirectional synchronous motion and improve the balance and efficiency of transmission.
[0007] Preferably, the lower end of the rotating rod is rotatably connected to the moving platform, and the positions of gear one and gear two are located inside the moving platform. The internal arrangement of the gears helps to protect them from the influence of the external environment and reduce wear.
[0008] Preferably, the inner wall of the mobile platform is detachably connected to an opening and closing cover by a snap fastener. The opening and closing cover is located on the outside of the second motor. The detachable design facilitates quick maintenance of internal parts and reduces equipment downtime.
[0009] Preferably, a shield is fixedly connected to the outer surface of the main body of the machining center, and the positions of sprocket one, chain and sprocket two are located inside the shield. The shield shields the sprocket and chain to prevent collisions with external machinery.
[0010] Preferably, the outer surface of the protective cover is provided with a groove, and the inner wall of the groove is slidably connected to the baffle. The groove design facilitates the smooth movement of the baffle, allowing the baffle to move along a predetermined path.
[0011] Preferably, the outer surface of the movable frame is slidably connected to the main body of the machining center, and the position of the lead screw one is located below the lead screw two. The layout of lead screw one below lead screw two makes reasonable use of space, has a compact structure, and is conducive to the overall mechanical layout. Beneficial effects
[0012] This technical solution's three-line rail vertical machining center with a rotatable worktable allows for the rotation of the worktable when machining long workpieces. Driven by motor two, the worktable can rotate, moving the other end of the workpiece into the main body of the machining center, enabling comprehensive machining of long workpieces and shortening workpiece position adjustment time. Driven by motor one, the moving table can move the worktable along with it, facilitating the rotation of the worktable outside the main body of the machining center. Simultaneously, when the worktable moves to the outside, the baffle also moves, exposing the machining area of the main body of the machining center for easy maintenance by operators.

A gear 7 is fixedly connected to the output end of the motor 6. A gear 8 meshes with the outer surface of gear 7. A rotating rod 9 is fixedly connected to the inner wall of gear 8, serving as a rotary connector for adjusting the rotation of the component. This rod is a metal shaft or rod equipped with bearings or support points. Rotation via the support connects to gear 8, enabling angle adjustment. The upper part of the rotating rod 9... The end is fixedly connected to a worktable 10, which mainly consists of a platform and clamping device, and is used to place and fix the workpiece. It is the main support surface for processing. The outer surface of the lead screw 13 is fixedly connected to a sprocket 11. The outer surface of the sprocket 11 is meshed with a chain 12. The inner wall of the chain 12 is meshed with a sprocket 2 13. The inner wall of the sprocket 2 13 is fixedly connected to a lead screw 2 14. The outer surface of the lead screw 2 14 is threadedly connected to a baffle 15, which is used to shield and reduce the splashing of splashes or impurities.

[0023] Working principle: When machining long workpieces, the workpiece is clamped on the worktable 10. After machining one end of the workpiece, the motor 6 drives the gear 7, which in turn drives the rotating rod 9 to rotate. The rotating rod 9 rotates the worktable 10, moving the other end of the workpiece into the machining center body 1, thus enabling full machining of long workpieces and shortening the workpiece position adjustment time. The motor 2 drives the lead screw 3, which moves the moving frame 4, threaded to the lead screw 3, along with the moving table 5 and the worktable 10, facilitating the rotation of the worktable 10 on the outside of the machining center body 1. Simultaneously, when the worktable 10 moves to the outside, the sprocket 11 on the lead screw 3 rotates, transmitting power from the sprocket 11 to the sprocket 13 via the chain 12, causing the lead screw 14 to rotate. This causes the baffle 15, threaded to the lead screw 14, to move as well, exposing the machining area of the machining center body 1 for easy maintenance by the operator.
