Description

Technical Field

[0001] This utility model relates to the field of magnetic chuck technology, specifically to the magnetic chuck structure for CNC machining centers. Background Technology

[0002] The magnetic chucks used in CNC machining centers attract workpieces to the top of the machining table using magnetism. However, after machining, workers need to manually separate the workpiece from the magnet. When the magnetism is strong, it can be strenuous for workers, failing to reduce their workload or improve work efficiency.

[0003] Therefore, this solution proposes a magnetic chuck structure for CNC machining centers to address the aforementioned issues. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a magnetic chuck structure for CNC machining centers.

[0005] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows: A magnetic chuck structure for a CNC machining center includes a machining table. Magnetic chuck mechanisms are equidistantly arranged on the top of the machining table. A square annular groove is formed on the top of the machining table, and springs and a frame plate are arranged within the square annular groove. The springs are equidistantly arranged around the bottom of the frame plate, and the bottom ends of the springs are connected to the machining table. The magnetic chuck mechanism includes a groove, a mounting plate, a mounting slot, a magnet, an equipment slot, and a hydraulic cylinder. The groove is equidistantly formed on the top of the machining table, the mounting plate is disposed within the groove, the mounting slot is formed on the top of the mounting plate, the magnet is embedded in the mounting slot, the equipment slot is equidistantly formed within the machining table, and the equipment slot is connected to the groove. The hydraulic cylinder is embedded in the equipment slot, and the output end of the top of the hydraulic cylinder is connected to the mounting plate.

[0006] Preferably, the processing table has a first limiting groove, which is symmetrically arranged on both sides of the groove, and the first limiting groove is connected to the groove.

[0007] Preferably, a first limiting block is provided in the first limiting groove, and the first limiting block is connected to the mounting plate.

[0008] Preferably, the processing table has a stabilizing groove, which is connected to the groove and is symmetrically arranged on the left and right sides of the bottom of the groove. A vertical plate is provided in the stabilizing groove, and the top of the vertical plate is connected to the mounting plate.

[0009] Preferably, a second limiting block is provided at the bottom of the left and right sides of the outer wall of the frame plate and at the middle of the bottom of the left and right sides of the inner wall.

[0010] Preferably, the processing table has a second limiting groove, which is connected to a square annular groove, and the second limiting block is disposed in the second limiting groove.

[0011] The beneficial effects of this utility model are reflected in:

[0012] This invention uses a magnet to attract and fix the workpiece. After the workpiece is processed, the hydraulic cylinder is activated to lower the magnet. Due to the limitation of the processing table, the workpiece will continue to stay on the top surface of the processing table, eliminating the need for workers to separate the workpiece from the magnet, thereby reducing labor intensity and improving work efficiency. By setting a first limiting block and a first limiting groove, the mounting plate can be restricted so that the top surface of the mounting plate does not exceed the top surface of the processing table. In conjunction with the stabilizing groove and the vertical plate, the mounting plate is made more stable when it is raised and lowered. By setting a second limiting groove and a second limiting block, the frame plate can be restricted to prevent the frame plate from detaching from the square ring groove. Attached Figure Description

Magnetic chuck mechanisms 2 are equidistantly arranged on the top of the machining table 1. A square annular groove 3 is formed on the top of the machining table 1. Springs 4 and a frame plate 5 are arranged within the square annular groove 3. The springs 4 are equidistantly arranged around the bottom perimeter of the frame plate 5, and their bottom ends are connected to the machining table 1. The magnetic chuck mechanism 2 includes a groove 21, a mounting plate 22, a mounting slot 23, a magnet 24, an equipment slot 25, and a hydraulic cylinder 26. The groove 21 is equidistantly formed on the top of the machining table 1. The mounting plate 22 is disposed within the groove 21. The mounting slot 23 is formed on the top of the mounting plate 22. The magnet 24 is embedded in the mounting slot 23. The equipment slot 25 is equidistantly formed within the machining table 1 and is connected to the groove 21. The hydraulic cylinder 26 is embedded in the equipment slot 25, and its output end is connected to the mounting plate 22.

[0024] In one embodiment, please refer to the appendix to the specification. Figure 2 and 3 As shown, a first limiting groove 6 is provided in the processing table 1. The first limiting groove 6 is symmetrically arranged on both sides of the groove 21. The first limiting groove 6 is connected to the groove 21. A first limiting block 7 is provided in the first limiting groove 6. The first limiting block 7 is connected to the mounting plate 22 and restricts the mounting plate 22 so that the top surface of the mounting plate 22 will not be higher than the top surface of the processing table 1.

[0025] In one embodiment, please refer to the appendix to the specification. Figure 2 and 3 The processing table 1 has a stabilizing groove 8, which is connected to the groove 21. The stabilizing groove 8 is symmetrically arranged on the left and right sides of the bottom of the groove 21. A vertical plate 9 is provided in the stabilizing groove 8, and the top of the vertical plate 9 is connected to the mounting plate 22, so that the mounting plate 22 is more stable when it is raised and lowered.

The processing table 1 is provided with a second limiting groove 11. The second limiting groove 11 is connected to the square annular groove 3, and the second limiting block 10 is set in the second limiting groove 11 to limit the frame plate 5 and prevent the frame plate 5 from leaving the square annular groove 3.

[0027] In use, the workpiece is attracted and fixed by the magnet 24. After the workpiece is processed, the hydraulic cylinder 26 is opened to lower the magnet 24. Due to the limitation of the processing table 1, the workpiece will continue to stay on the top surface of the processing table 1. There is no need for the operator to separate the workpiece from the magnet 24, thereby reducing labor intensity and improving work efficiency. By setting the first limiting block 7 and the first limiting groove 6, the mounting plate 22 can be limited so that the top surface of the mounting plate 22 will not be higher than the top surface of the processing table 1. With the help of the stabilizing groove 8 and the vertical plate 9, the mounting plate 22 is more stable when it is raised and lowered. By setting the second limiting groove 11 and the second limiting block 10, the frame plate 5 can be limited to prevent the frame plate 5 from falling out of the square annular groove 3.
