Description

Technical Field

[0001] The utility model relates to the technical field of turning-milling compound machine tools, in particular to a turning-milling separation mechanism of a turning-milling compound machine tool. Background Art

[0002] The milling separation mechanism of a milling machine is a mechanical structure that allows the machine to quickly switch between turning and milling operations. This mechanism usually includes a rotatable turret (or tool magazine) and a movable worktable. In turning mode, the positions of the turret and the workpiece are fixed, while in milling mode, the turret rotates to the milling position and the workpiece moves to the milling position.

[0003] After searching, the publication number CN217668274U discloses a milling separation mechanism for a milling compound machine tool, which relates to the technical field of milling compound machine tools and solves the problem that the two shafts of the existing compound machine tool are hard-connected when used in combination through a separation mechanism, which is easy to damage the processing tool and delay the processing progress. A milling separation mechanism for a milling compound machine tool includes an operating shaft; the operating shaft is rotatably connected to the bottom of a fixed seat. The connecting shaft and the operating shaft are softly connected through a clutch pressure column, so that when the operating shaft encounters an obstacle during the rotation processing, the clutch pressure column can move upward to release the driving relationship between the connecting shaft and the operating shaft, thereby protecting the operating shaft and the processing tool installed at the bottom of the operating shaft. It is easy to use, safer and more stable. In this application, different material workpieces are processed and protected by structures such as pressure top springs. Such a setting makes it difficult to quickly achieve separation and connection, resulting in increased downtime during the production process, thereby reducing overall production efficiency.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3The utility model provides an embodiment: a turning and milling separation mechanism of a turning and milling compound machine tool, including an outer shell 1, a rotating rod 2 is rotatably connected inside the outer shell 1, a gear 3 is fixedly connected to one end of the outer wall of the rotating rod 2, an L-shaped rack 4 is slidably connected inside the outer shell 1, the gear 3 is meshed with the L-shaped rack 4, one end of the L-shaped rack 4 is fixedly connected to a slider 5, one side of the outer wall of the slider 5 is fixedly connected to a transmission shaft 6, the other side of the outer wall of the slider 5 is fixedly connected to a fixed block 7, the outer wall of the fixed block 7 is rotatably connected to a rotating shaft 8, and the outer wall of the rotating shaft 8 A clamping block 9 is fixedly connected, a torsion spring 10 is arranged inside the rotating shaft 8, one end of the torsion spring 10 is fixedly connected to the outer wall of the fixed block 7, a fixing sleeve 11 is fixedly connected inside the outer shell 1, a push block 12 is slidably connected inside the fixing sleeve 11, a telescopic rod 13 is fixedly connected to the outer wall of the push block 12, a telescopic spring 14 is sleeved on the outer wall of the telescopic rod 13, one end of the telescopic spring 14 is fixedly connected to the outer wall of the push block 12, the other end of the telescopic spring 14 is fixedly connected to the inner part of the fixing sleeve 11, and a mounting assembly is arranged on the outer wall of the outer shell 1;

[0024] Specifically, the rotating rod 2 will be rotated first, driving the gear 3 to rotate, and the gear 3 will mesh with the L-shaped rack 4, so the L-shaped rack 4 will move inside the outer shell 1, and with the movement of the L-shaped rack 4, the slider 5 and the transmission shaft 6 will also move accordingly. The movement of the slider 5 further drives the movement of the clamping block 9, so that it gradually enters the interior of the fixed sleeve 11. In this process, the torsion spring 10 plays a key role. When the clamping block 9 approaches the fixed sleeve 11, the torsion spring 10 will reverse and push the clamping block 9 to smoothly clamp into the interior of the fixed sleeve 11 for fixation, thereby realizing the connection function. In order to separate, the operator only needs to press the push block 12 to apply a certain pressure to the clamping block 9. This pressure causes the clamping block 9 to rotate between the rotating shaft 8. When it is rotated to a certain angle, the separation can be achieved by rotating the rotating rod 2 in the opposite direction, making the connection and separation process simple and efficient.

[0025] Reference Figure 4 The mounting assembly includes a mounting block 15, the outer wall of the mounting block 15 is fixedly connected to the outer wall of the outer shell 1, the outer wall of the mounting block 15 is rotatably connected to a rotating sleeve 16, the inner wall of the rotating sleeve 16 is fixedly connected to a connecting rod 17, the interior of the connecting rod 17 is fixedly connected to a screw 18, the outer wall of the connecting rod 17 is rotatably connected to the interior of the mounting block 15, the outer wall of the screw 18 is threadedly connected to a sliding sleeve 19, the outer wall of the sliding sleeve 19 is rotatably connected to a push rod 20, one end of the push rod 20 is rotatably connected to a clamping block 21, the outer wall of the push rod 20 is slidably connected to the interior of the mounting block 15, the outer wall of the mounting block 15 is slidably connected to a mounting sleeve 22, and the outer wall of the clamping block 21 is slidably connected to the interior of the mounting block 15 and the mounting sleeve 22;

[0026] Specifically, when the rotating sleeve 16 is driven to start working, the connecting rod 17 is driven to perform corresponding movement, driving the rotating sleeve 16 and the screw 18 to ensure that the movement between the two can be smoothly transmitted. As the connecting rod 17 rotates, the screw 18 also starts to rotate inside the mounting block 15. The rotational movement of the screw 18 prompts the sliding sleeve 19 to slide on the outer wall of the screw 18. The sliding sleeve 19 is cleverly designed and can slide freely on the screw 18 while maintaining a stable connection, thereby achieving precise control of the push rod 20. As the sliding sleeve 19 slides, the push rod 20 starts to move. The push rod 20 is an actuator in the mechanical system, which determines the position change of the block 21. Through the movement of the push rod 20, the block 21 slides inside the mounting block 15 and the mounting sleeve 22. The block 21 can move flexibly between the mounting block 15 and the mounting sleeve 22 to achieve the fastening and disassembly of the milling head.

[0027] Working principle: When the turning and milling separation mechanism of the turning and milling compound machine tool is needed, first, the gear 3 is driven to rotate by rotating the rotating rod 2, thereby driving the L-shaped rack 4 to move inside the outer shell 1, and then driving the slider 5 and the transmission shaft 6 to move, and then the movement of the slider 5 drives the clamping block 9 to move to the inside of the fixed sleeve 11. At this time, the reverse rotation of the torsion spring 10 drives the clamping block 9 to be clamped into the inside of the fixed sleeve 11 for fixing, thereby realizing the connection, and then the push block 12 is pressed to apply pressure to the clamping block 9, so that the clamping block 9 is between the rotating shaft 8. The rotating sleeve 16 is driven to rotate, and when it is rotated to a certain angle, the separation can be achieved by rotating the rotating rod 2 in the opposite direction, thereby achieving the effect of convenient connection and separation. The screw rod 18 is driven to rotate inside the mounting block 15 through the connecting rod 17, and then the sliding sleeve 19 slides on the outer wall of the screw rod 18, and then one end of the push rod 20 is moved by moving the push rod 20, so that the block 21 is driven to slide inside the mounting block 15 and the mounting sleeve 22 through the other end of the push rod 20, and then the milling head is conveniently disassembled and assembled through the mounting sleeve 22.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
