Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a multi-axis linkage optimization structure for an ultra-high-speed CNC machine tool guide. Background Technology

[0002] Existing conventional CNC machine tools require tool adjustment and calibration during each machining operation. After completing one machining operation, tool replacement is required before proceeding to the next, which necessitates tool adjustment and other operations. The actual machining steps are complex. In addition, the machine needs to be stopped for clamping or unclamping workpieces, so the percentage of actual machining time is not large. Therefore, the overall machining efficiency is low, especially for precision machining of single pieces and large batches.

[0003] Existing technology, such as publication number CN217453223U, provides a dual-rotary-table multi-station CNC linkage machine, including a machine tool base. A linear guide rail is arranged at the top of the machine tool base, and two rotary indexing worktables are mounted on the linear guide rails. Several workpiece clamping and positioning platforms are evenly spaced at the top of the rotary indexing worktables. Several three-axis linkage CNC mechanisms are circumferentially arranged at the top of the machine tool base outside the linear guide rails, and these three-axis linkage CNC mechanisms cooperate with the rotary indexing worktables. This utility model, through a series of structural features, enables the dual-rotary-table multi-station CNC linkage machine to perform multi-station operations, facilitating simultaneous clamping of multiple workpieces, and enabling continuous and step-by-step processing. This optimizes the processing process while extending machining time, thereby improving processing efficiency.

[0004] The current scheme uses two sets of rotary indexing tables with several workpiece clamping and positioning platforms evenly spaced on top of the tables to enable simultaneous processing by multiple workpiece clamping and positioning platforms. Efficiency is further improved by rotating different rotary indexing tables. However, in practical use, for parts requiring multi-faceted machining, multiple disassembly and reassembly of the workpiece are still necessary, which remains cumbersome. Therefore, we propose an optimized multi-axis linkage structure for the guide mechanism of an ultra-high-speed CNC machine tool. Summary of the Invention

[0005] The purpose of this utility model is to provide a multi-axis linkage optimization structure for a high-speed CNC machine tool guide. This multi-axis linkage optimization structure for a high-speed CNC machine tool guide solves the problem that when dealing with parts that require multi-faceted processing, it is still necessary to disassemble and assemble the workpiece multiple times, which is still quite troublesome.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-axis linkage optimization structure for an ultra-high-speed CNC machine tool guide includes a worktable, with support seats fixedly connected to both sides of the top center position of the worktable;

[0008] An X-axis adjusting frame is rotatably connected between the two support bases. The rotation axis of the X-axis adjusting frame is parallel to the X-axis. The inner wall of the X-axis adjusting frame rotates to form a Y-axis adjusting frame. The rotation axis of the Y-axis adjusting frame is parallel to the Y-axis.

[0009] Preferably, a row of T-shaped blocks is fixedly connected to the bottom of the support base, and the T-shaped blocks are used to be embedded in the T-shaped grooves on the workbench.

[0010] Preferably, the support base is equipped with a servo motor that drives the X-axis adjustment frame to rotate, and the servo motor is equipped with a brake. The X-axis adjustment frame is equipped with drive components at the connection points of the two rotating shafts on the Y-axis adjustment frame.

[0011] Preferably, the inner wall of the Y-axis adjusting frame is fixedly connected to several electric cylinders, and the telescopic end of the electric cylinder is fixedly connected to a flexible gripper.

[0012] Preferably, the drive assembly includes a worm gear, which is disposed outside the X-axis adjustment frame and connected to the rotating shaft of the Y-axis adjustment frame. Support blocks are fixedly connected to the outer wall of the X-axis adjustment frame on both sides of the worm gear. Worms are meshed and connected above and below the worm gear, and the worms are rotatably connected between the support blocks. Gears are fixedly sleeved at both ends of the worms. A servo motor for driving the worms to rotate is disposed inside the support blocks, and the gears on the same side of the two worms mesh with each other.

[0013] Preferably, a spherical groove is formed on the top of the workbench at the position between the two support bases, and an arc-shaped groove is formed on the inner wall of the spherical groove.

[0014] Preferably, the workbench has several drainage channels at the bottom of the arc-shaped groove.

[0015] By employing the above technical solution, this utility model provides an optimized multi-axis linkage structure for guiding ultra-high-speed CNC machine tools. It possesses at least the following beneficial effects:

[0016] I. This utility model, by setting up an X-axis adjustment frame and a Y-axis adjustment frame, allows the workpiece held by the flexible gripper to be angled around the X-axis following the X-axis adjustment frame or angled around the Y-axis adjustment frame, thus avoiding the troublesome problem of having to disassemble and assemble the workpiece multiple times when dealing with parts that require multi-faceted processing.

[0017] Second, the brake on the servo motor inside the support base of this utility model can ensure the stability of the adjusted X-axis adjustment frame. The Y-axis adjustment frame is rotated and adjusted by two worm gears meshing with a worm wheel. The non-reversible transmission characteristic of the worm gears can ensure the stability of the Y-axis adjustment frame during processing. Attached Figure Description

[0025] 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.

[0026] An optimized multi-axis linkage structure for guiding ultra-high-speed CNC machine tools, such as... Figure 1 - Figure 5As shown, the system includes a worktable 1. Support bases 2 are fixedly connected to both sides of the top center of the worktable 1. An X-axis adjusting bracket 3 is rotatably connected between the two support bases 2. The rotation axis of the X-axis adjusting bracket 3 is parallel to the X-axis. A Y-axis adjusting bracket 4 rotates from the inner wall of the X-axis adjusting bracket 3, and the rotation axis of the Y-axis adjusting bracket 4 is parallel to the Y-axis. A row of T-shaped locking blocks 21 is fixedly connected to the bottom of the support base 2. The T-shaped locking blocks 21 are used to fit into the T-slots on the worktable 1. The interior of the support base 2 is equipped with a mechanism to drive the X-axis adjusting bracket 3 to rotate. The servo motor is equipped with a brake. Drive components 5 are respectively installed at the connection points of the two rotating shafts on the Y-axis adjustment frame 4 on the X-axis adjustment frame 3. Several electric cylinders 41 are fixedly connected to the inner wall of the Y-axis adjustment frame 4, and flexible grippers 42 are fixedly connected to the telescopic ends of the electric cylinders 41. The number and position of the electric cylinders 41 and the flexible grippers 42 can be adjusted according to the actual needs of the workpiece. When dealing with some workpieces with large mass, the overall stability of the workpiece can be improved by using a support structure on the workpiece.

[0027] In this embodiment, by setting up an X-axis adjustment frame 3 and a Y-axis adjustment frame 4, the workpiece held by the flexible gripper 42 can be angled around the X-axis following the X-axis adjustment frame 3 or around the Y-axis adjustment frame 4. This avoids the troublesome problem of having to disassemble and reassemble the workpiece multiple times when dealing with parts that require multi-faceted processing. In actual use, the flexible gripper 42 is brought close to the surface of the part by the electric cylinder 41. When the workpiece needs to be processed on a plane with other angles, the X-axis adjustment frame 3 can be rotated around the X-axis direction by the servo motor set inside the support base 2 to adjust the angle. The brake set on the servo motor can ensure the stability of the X-axis adjustment frame 3 after adjustment. Alternatively, the Y-axis adjustment frame 4 can be rotated around the X-axis direction by the drive component 5 set on the Y-axis adjustment frame 4 to adjust the angle, which is convenient for processing different processing surfaces.

[0028] like Figure 3 , Figure 4As shown, preferably, the drive assembly 5 includes a worm gear 52, which is located outside the X-axis adjustment frame 3 and connected to the rotating shaft of the Y-axis adjustment frame 4. Support blocks 51 are fixedly connected to the outer wall of the X-axis adjustment frame 3 on both sides of the worm gear 52. Worms 53 are meshed above and below the worm gear 52, and the worms 53 are rotatably connected between the support blocks 51. Gears 54 are fixedly sleeved at both ends of the worms 53. A servo motor for driving the worms 53 to rotate is installed inside the support blocks 51. The gears 54 on the same side of the two worms 53 mesh with each other. A spherical groove 11 is provided on the top of the worktable 1 between the two support seats 2. An arc groove 12 is provided on the inner wall of the spherical groove 11. By providing the spherical groove 11 and the arc groove 12, the collision between the X-axis adjustment frame 3 and the drive assembly 5 can be avoided. Several drainage channels 13 are provided on the worktable 1 at the bottom of the arc groove 12 for draining coolant.

[0029] In this embodiment, a servo motor installed inside the support block 51 drives one of the worm gears 53 to rotate. Through the meshing of two gears 54, the other worm gear 53 rotates in the opposite direction, so as to facilitate the driving of the worm wheel 52 to drive the Y-axis adjustment frame 4 to rotate for angle adjustment. The non-reversible transmission characteristic of the worm gears 53, which drives the Y-axis adjustment frame 4 to rotate and adjust through the meshing of the two worm gears 53 and the worm wheel 52, can ensure the stability of the Y-axis adjustment frame 4 during processing.

[0030] In use, the multi-axis linkage optimization structure of the ultra-high-speed CNC machine tool guide of this utility model uses an electric cylinder 41 to drive the flexible gripper 42 to approach and clamp the surface of the workpiece. When the workpiece needs to be machined to a plane with other angles, the angle can be adjusted by the servo motor inside the support block 2 driving the X-axis adjustment frame 3 to rotate around the X-axis direction, or by the drive component 5 inside the Y-axis adjustment frame 4 driving the Y-axis adjustment frame 4 to rotate around the X-axis direction. When the drive component 5 is driven, the servo motor inside the support block 51 drives one of the worm gears 53 to rotate. Through the meshing of two gears 54, the other worm gear 53 rotates in the opposite direction, so as to facilitate the drive worm wheel 52 to drive the Y-axis adjustment frame 4 to rotate for angle adjustment.
