Description

Technical Field

[0001] This application relates to the field of numerically controlled grinding machines, and more particularly to a three-axis intelligent numerically controlled grinding machine. Background Art

[0002] A three-axis numerically controlled grinding machine is a high-precision machining device that controls the movement of a worktable (or workpiece) in three directions through numerical control technology to achieve precision grinding of the workpiece surface. The three axes usually refer to the X-axis, Y-axis, and Z-axis. In a three-axis numerically controlled grinding machine, the X-axis usually controls the movement of the grinding head in the horizontal direction, the Y-axis controls the movement of the worktable in the vertical direction, and the Z-axis controls the movement of the grinding head in the front-rear direction. The movement control of these three axes can accurately position and grind the workpiece surface.

[0003] During operation, the workpiece needs to be fixed in the three-axis numerically controlled grinding machine so that the grinding head acts on the workpiece processing position. However, for some workpieces that need to be ground on multiple surfaces, after the single-sided processing is completed, the workpiece needs to be removed and the grinding position needs to be adjusted. However, repeatedly disassembling, installing, and adjusting the placement position of the workpiece is time-consuming and laborious, increasing the labor intensity of people's operation and also having a certain impact on the overall processing efficiency of the workpiece.

[0004] Regarding the above related technologies, the inventor believes that there is a defect that it is inconvenient to repeatedly disassemble and install the workpiece to adjust the processing surface when the workpiece is processed in a three-axis numerically controlled grinding machine. Therefore, a three-axis intelligent numerically controlled grinding machine is proposed to solve the above problems. Utility Model Content

[0019] The following further elaborates on this application in conjunction with the attached Figures 1-4 drawings.

[0020] The embodiment of this application discloses a three-axis intelligent CNC grinding machine. Referring to Figures 1-4 , the three-axis intelligent CNC grinding machine includes a main body 1 of the CNC grinding machine. An electric lifting table 6 is arranged on the upper surface of the main body 1 of the CNC grinding machine. The inside of the electric lifting table 6 is driven by a cylinder, and the lifting plate 7 is adjusted to move up and down through the cylinder. The lifting plate 7 is movably installed at the top end of the electric lifting table 6. Support plates 8 are welded to both side edges of the upper surface of the lifting plate 7. A mounting frame 9 is rotatably installed between the two support plates 8. One side of the mounting frame 9 extends outside the support plate 8 and is welded with a movable circular plate 10. A fixed frame 11 is fixedly installed on one side of a single support plate 8. A bidirectional lead screw 12 is rotatably installed inside the fixed frame 11. Guide rods 13 are welded near both ends of the bidirectional lead screw 12 inside the fixed frame 11. A movable block 14 is sleeved on the outer surfaces of the bidirectional lead screw 12 and the guide rod 13. One end of the movable block 14 is rotatably installed with a movable connecting rod 15. One end of the movable connecting rod 15 is hinged at one end of the movable circular plate 10. A threaded hole is formed through the middle of one side of the movable block 14. External threads with opposite thread patterns are respectively formed on both sides of the outer surface of the bidirectional lead screw 12. The bidirectional lead screw 12 is located inside the threaded hole. First through holes are symmetrically formed through one side of the movable block 14. One side of the outer surface of the guide rod 13 is located inside the first through hole. A limiting mechanism is further arranged inside the mounting frame 9 for fixing the workpiece inside the mounting frame 9.

[0021] By fixing the workpiece inside the mounting frame 9 and rotating the bidirectional lead screw 12 to drive the movable block 14 to move, the guide rod 13 guides and supports the moving movable block 14, keeping the movable block 14 in a stable moving state inside the fixed frame 11, adjusting the distance between the two movable blocks 14, enabling the moving movable block 14 to drive the movable connecting rod 15 to rotate, and further enabling the movable connecting rod 15 to drive the movable circular plate 10 to rotate synchronously, so that the rotating movable circular plate 10 drives the workpiece inside the mounting frame 9 to adjust the angle, and different positions of the workpiece are placed on the upper surface of the electric lifting table 6, reflecting the angle adjustment effect of the workpiece on the electric lifting table 6.

[0022] Referring to Figure 3 and Figure 4, the limiting mechanism includes a fixed rod 16, which is symmetrically welded to the two side edges of the inner wall of the mounting frame 9. A limiting screw 17 is threadedly connected to the middle of one end of the mounting frame 9. One end of the limiting screw 17 is rotatably installed with a limiting pressing plate 18 inside the mounting frame 9. Second through holes are symmetrically and penetratingly opened on both side edges of the limiting pressing plate 18. One side of the outer surface of the fixed rod 16 is located inside the second through hole, and the fixed rod 16 and the second through hole are mutually fitted.

[0023] By placing the workpiece inside the mounting frame 9 and rotating the limiting screw 17 to push the limiting pressing plate 18 to move along the outer surface of the fixed rod 16, the fixed rod 16 guides and supports the moving workpiece, and the limiting pressing plate 18 abuts the workpiece inside the mounting frame 9 and fixes it, reflecting the installation and fixing effect of the mounting frame 9 cooperating with the limiting pressing plate 18 for workpieces of different sizes.

[0024] Refer to Figure 1 and Figure 2 , a fixed guide rail 2 is provided at the inner bottom of the main body 1 of the CNC grinding machine. A guiding bracket 3 is movably installed on the outer surface of the fixed guide rail 2. A grinding device 4 is movably installed at the inner top of the guiding bracket 3. A grinding head 5 is rotatably installed at the bottom end of the grinding device 4.

[0025] By moving the guiding bracket 3 along the outer surface of the fixed guide rail 2 and moving the grinding device 4 along the inner top of the guiding bracket 3, the position of the grinding head 5 above the main body 1 of the CNC grinding machine is adjusted to different positions for processing. The electric lifting table 6 drives the lifting plate 7 to perform a lifting movement, and the rising lifting plate 7 places the workpiece on the outer surface of the grinding head 5, and the grinding head 5 grinds the upper surface of the workpiece, reflecting the position adjustment effect of the grinding head 5.

[0026] The implementation principle of the three-axis intelligent numerical control grinding machine in the embodiment of the present application is as follows: Place the workpiece inside the mounting frame 9, rotate the limit screw 17 to push the limit pressure plate 18 to move along the outer surface of the fixed rod 16, so that the limit pressure plate 18 abuts the workpiece inside the mounting frame 9 and fixes it. At the same time, rotate the bidirectional lead screw 12 to drive the movable block 14 to move, so that the guide rod 13 guides and supports the moving movable block 14, keeping the movable block 14 in a stable moving state inside the fixed frame 11, adjusting the distance between the two movable blocks 14, so that the moving movable block 14 drives the movable connecting rod 15 to rotate, and then the movable connecting rod 15 drives the movable circular plate 10 to rotate synchronously, so that the rotating movable circular plate 10 drives the workpiece inside the mounting frame 9 to adjust the angle, so that different positions of the workpiece are placed on the upper surface of the electric lifting table 6, and the guide bracket 3 moves along the outer surface of the fixed guide rail 2, so that the grinding device 4 moves along the inner top of the guide bracket 3, adjusting the grinding head 5 to be placed at different positions above the numerical control grinding machine main body 1 for processing, so that the electric lifting table 6 drives the lifting plate 7 to move up and down, so that the rising lifting plate 7 places the workpiece on the outer surface of the grinding head 5, and the grinding head 5 grinds the upper surface of the workpiece. The input ends of the power supplies of the guide bracket 3, the grinding device 4 and the driving part of the electric lifting table 6 are all electrically connected to the output end of the external power supply; compared with the prior art, this solution has the effect of facilitating multi-angle adjustment of the workpiece during processing, improving the overall processing efficiency of the workpiece, and solving the problem that it is rather inconvenient to repeatedly disassemble and assemble the workpiece when adjusting the placement position.
