Abstract
Description
Technical Field
[0001] This utility model relates to the field of vertical milling and turning machine tool technology, specifically a novel C-axis braking structure for a vertical milling and turning machine tool. Background Technology
[0002] Vertical turning and milling machine tools drive the cutting tool to rotate through the spindle, while the worktable drives the workpiece to rotate and move. The relative motion between the cutting tool and the workpiece enables various machining processes such as turning, milling, boring, drilling, and reaming.
[0003] When using the milling function, vertical milling and turning machines need to keep the worktable stationary, which requires a braking structure. Conventionally, a disc brake structure is added to achieve braking.
[0004] However, existing vertical milling and turning machines use a conventional butterfly brake structure when performing milling functions. This structure is complex, costly, inconvenient to maintain, and affects the performance. To address these issues, a novel C-axis brake structure for vertical milling and turning machines is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a novel C-axis brake structure for vertical milling and turning machines, which solves the problems of the conventional butterfly brake structure used in the background technology, which is complex, costly, inconvenient to maintain, and affects the performance.

When braking is required, high-pressure oil enters from the P port, driving the piston to move upward. The spring contracts, pressing the flange together. The flange and gear are fixed together, keeping the large gear ring stationary.

[0021] By adopting the above technical solutions, the pad's performance can be enhanced.

[0026] 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.
[0027] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0028] Combination Figure 1 This utility model discloses a novel C-axis braking structure for a vertical milling and turning machine, comprising a base 1, a brake seat 12 on the top of the base 1, and the brake seat 12 being connected to the base 1 by bolts for easy installation and disassembly. A cover 2 is provided on the bottom inner wall of the brake seat 12, and the brake seat 12 and cover 2 are connected by bolts, with a first O-ring 3 between them to increase sealing. A bearing cover 13 is provided on the top of the brake seat 12. A piston 4 is slidably connected to the inner wall of the brake seat 12. When high-pressure oil is discharged from port P 16, it drives the piston 4 to move upward, thereby achieving braking. The cover 13 and the brake seat 12 are connected by bolts. A first O-ring 3 is provided between the brake seat 12 and the cover 2 to increase the sealing. The spring 8 is in contact with the gear 14. A second O-ring 6 is provided on the outer ring of the piston 4 to increase the sealing between the piston 4 and the brake seat 12. A second bearing 11 is provided on the inner ring of the brake seat 12 to ensure the accuracy of rotation. A P port 16 is provided on one side of the outer ring of the brake seat 12 to facilitate the delivery of high-pressure oil into the piston 4 and push the piston 4 to move. A bearing cover 13 is provided on the top of the pad 10.
[0029] Combination Figure 1A piston 4 is installed on the top of the cover 2. When the piston 4 is subjected to high-pressure oil entering from P, it can drive the piston 4 to move. A first bearing 5 is slidably connected to the bottom of the inner wall of the piston 4. A spring seat 7 is slidably connected to the inner ring of the first bearing 5. When the piston 4 moves, it will cause the spring seat 7 to move, and then the spring 8 will be compressed, so that the piston 4 can contact the flange 9. A spring 8 is installed on the inner wall of the spring seat 7. A flange 9 is fixedly connected to the lower center of the inner wall of the brake seat 12. A gear 14 is installed on the top of the flange 9. When the flange 9 stops, the gear 14 can stop, thereby driving the large gear 15 to stop. A large gear ring 15 is meshed with the outer ring of the gear 14. A gasket 10 is installed on the outer ring of the flange 9. A second bearing 11 is slidably connected to the outer ring of the gear 14.
[0030] Working principle: During use, the machine tool's worktable is fixed on the large gear ring 15, and the brake seat 12 is installed above the base 1. When braking is required, high-pressure oil is simply discharged from the P port 16, which drives the piston 4 to move upward. The spring seat 7 moves, pushing the spring 8 to contract, which presses the flange 9 tightly. The flange 9 is then fixed together with the gear 14, thus stopping the gear 14 and keeping the large gear ring 15 stationary, achieving braking. The structure is simple and easy to install. During use, the first O-ring 3 between the cover 2 and the brake seat 12 increases the sealing, and a second O-ring 6 is also provided between the piston 4 and the brake seat 12 to increase the sealing.
