Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a pneumatic tool magazine door opening and closing structure. Background Art

[0002] With the continuous improvement of the degree of automation in the manufacturing industry, CNC machine tools, as the core equipment for precision machining, have a direct impact on the performance of the entire production line with their work efficiency and machining accuracy. The tool magazine that can store various types of tools is an indispensable part of CNC machine tools. Through the automatic tool change function, it can greatly shorten the tool change time and enable the machine tool to operate continuously. The tool magazine is usually equipped with a tool magazine door that can open and close automatically. When the tool magazine door is closed, it can effectively prevent dust, cutting chips and other contaminants from entering the tool magazine, keep the tool clean, reduce wear and rust, and extend the tool life.

[0003] The existing authorization number CN202020376292.X has published a straight-row fully enclosed automatic tool changing device for a machining center, which opens and closes the tool magazine door by setting a tool magazine door cylinder and a hinge structure outside the tool magazine door. However, it is found that the opening and closing structure will occupy a large machine tool space on the CNC machine tool and interfere with the normal operation of other components. Utility Model Content

[0004] In order to solve the above-mentioned problems in the background technology, the utility model provides a pneumatic tool magazine door opening and closing structure.

[0005] The solution adopted by the utility model to solve its technical problems is: a pneumatic tool magazine door opening and closing structure, including a tool magazine compartment for storing tool magazines, a tool magazine door and a pushing mechanism, the tool magazine door is movably arranged at the opening end of the tool magazine compartment and can rotate relative to the tool magazine compartment, the pushing mechanism includes a mounting seat fixedly arranged on both sides of the inner wall of the tool magazine compartment, a cylinder rotatably connected to the mounting seat and a pushing rod, one end of the pushing rod is fixedly connected to the gas rod inside the cylinder, and the other end is rotatably connected to the inner wall of the tool magazine door.

[0006] By adopting the above technical solution, the pushing mechanism is integrated into the tool magazine compartment, reducing the external space occupied by the tool magazine structure and avoiding interference with other parts of the machine tool. The two ends of the push rod are connected by rotation to follow the rotation trajectory of the door, ensuring that the push rod always maintains smooth transmission during the opening or closing process of the door, and will not get stuck or apply unnecessary lateral force due to the angle limitation caused by the fixed connection.

[0007] Furthermore, a rotating seat is provided on the top of the fixed seat and the inner wall of the tool magazine door, and joints that can be rotatably connected to the rotating seat are provided at both ends of the push rod, pins are provided on both sides of the joint, and adapter holes that can accommodate the pins are provided on both sides of the rotating seat.

[0008] By adopting the above technical solution, the joints at both ends of the push rod can rotate along the rotating seat, avoiding the jamming problem caused by the rigid connection.

[0009] Furthermore, a hinge is provided at the top of the opening end of the tool magazine door, and the tool magazine door is rotatably connected to the tool magazine bin via the hinge.

[0010] By adopting the above technical solution, the hinge connection allows the tool magazine door to rotate around a fixed axis to achieve the opening and closing of the tool magazine door.

[0011] Furthermore, a retaining edge is extended outwardly from the top edge of the opening end of the tool magazine door, and a buffering limiter for abutting against the tool magazine door is provided at the bottom of the retaining edge.

[0012] By adopting the above technical solution, the retaining edge can limit the tool magazine door to prevent its opening angle from being too large and occupying the Z-axis space of the machine tool, and the buffer limiter can prevent the tool magazine door from opening and colliding with the tool magazine bin to generate noise.

[0013] Furthermore, the tool magazine compartment opening end is provided with closing grooves on both sides corresponding to the closing of the tool magazine door, and the closing grooves are provided with magnetic suction parts for sucking the tool magazine door.

[0014] By adopting the above technical solution, the magnetic suction part can prevent the working vibration of the machine tool from causing the tool magazine door to expose a gap.

[0015] In summary, the beneficial effects of the utility model are:

[0016] 1. The utility model integrates the cylinder, the mounting seat and the push rod inside the tool magazine, thereby reducing the occupation of the external space of the machine tool and effectively avoiding mutual interference with other parts of the machine tool.

[0017] 2. The utility model connects the tool magazine door and the rotating seat by means of a rotating connection at both ends of the push rod, so that the push rod can rotate freely along the rotation trajectory of the tool magazine door, ensuring smooth transmission during the opening and closing process, avoiding jamming or additional lateral force that may be caused by a fixed connection, and improving the smooth opening and closing performance of the tool magazine door.

[0018] 3. The utility model limits the maximum opening angle of the tool magazine door by arranging a retaining edge and a buffer limiter at the bottom of the tool magazine door opening end, avoiding occupying too much Z-axis space, and reducing the impact and noise during opening through the buffering effect.

[0019] 4. The utility model provides additional adsorption force for the closing of the tool magazine door by means of the magnetic suction piece arranged in the closing groove. Even slight vibration when the machine tool is working will not cause the door body to loosen or produce gaps, thereby ensuring the sealing of the tool magazine, effectively isolating the intrusion of dust and cutting fluid, and protecting the tool.

[0028] like Figure 1 to Figure 2As shown, a pneumatic tool magazine door 2 opening and closing structure includes a tool magazine compartment 1 for storing tool magazines, a tool magazine door 2 and a pushing mechanism 3. The tool magazine door 2 is movably arranged at the opening end of the tool magazine compartment 1 and can rotate relative to the tool magazine compartment 1, and the pushing mechanism 3 includes a mounting seat 31 fixedly arranged on both sides of the inner wall of the tool magazine compartment 1, a cylinder 32 rotatably connected to the mounting seat 31, and a pushing rod 33. One end of the pushing rod 33 is fixedly connected to the internal gas rod of the cylinder 32, and the other end is rotatably connected to the inner wall of the tool magazine door 2.

[0029] The pushing mechanism 3 of this embodiment is integrated into the tool magazine 1 to avoid occupying the y-axis space of the machine tool. When the tool magazine door 2 is in a closed state, it is close to the open end of the tool magazine 1, effectively isolating the external environment and preventing dust, cutting debris and other contaminants from entering the tool magazine. At this time, the air rods of the cylinder 32 on both sides of the tool magazine 1 are in a retracted state, and the push rod 33 is also in an unextended position. When the numerical control system detects that the tool needs to be replaced, it sends a signal to the pneumatic control system to start the cylinder 32. After receiving the signal, the gas pressure in the cylinder 32 increases, pushing the piston and the connected air rod to extend in a predetermined direction, and the movement of the air rod is transmitted through the push rod 33 fixedly connected thereto. In addition, the two ends of the push rod 33 are rotatably connected to follow the rotation trajectory of the door, ensuring that the push rod 33 always maintains smooth transmission during the opening or closing of the door, and will not be stuck or apply unnecessary lateral force due to the angle limitation caused by the fixed connection.

[0030] like Figure 2 As shown, the top of the fixed seat and the inner wall of the tool magazine door 2 of this embodiment are both provided with a rotating seat 34, and both ends of the push rod 33 are provided with joints 35 that can be rotatably connected to the rotating seat 34, and both sides of the joint 35 are provided with pins 351, and both sides of the rotating seat 34 are provided with adapter holes 341 that can accommodate the pins 351. The joints 35 at both ends of the push rod 33 can rotate freely along the rotating seat 34 to ensure that the push rod 33 can smoothly follow the movement trajectory of the door when the tool magazine door 2 is opened or closed. No matter how the rotation angle of the door changes, smooth and unobstructed transmission can be maintained to avoid the jamming problem caused by rigid connection, and a large angle opening of the tool magazine door 2 can be achieved.

[0031] like Figure 1 As shown, a hinge 4 is provided at the top of the opening end of the tool magazine door 2 of this embodiment, and the tool magazine door 2 is rotatably connected to the tool magazine compartment 1 through the hinge 4. One side of the hinge 4 is fixed to the top of the tool magazine compartment 1 by screws, and the other side is fixed to the corresponding position on the top of the tool magazine door 2 by screws. The hinge 4 is connected so that the tool magazine door 2 and the tool magazine compartment 1 are hinged. The tool magazine door 2 can rotate around a fixed axis to realize the opening and closing of the tool magazine door 2.

[0032] like Figure 3As shown, the tool magazine door 2 of this embodiment has a retaining edge 5 extending outward from the top edge of the opening end, and the retaining edge 5 is parallel to the top of the tool magazine compartment 1. A buffering limiter 51 for contacting the tool magazine door 2 is provided at the bottom of the retaining edge 5, and the buffering limiter 51 is made of flexible material. The retaining edge 5 can limit the tool magazine door 2 and effectively prevent the tool magazine door 2 from closing too far and occupying the Z-axis space of the machine tool, and the buffering limiter 51 can avoid the noise generated by the tool magazine door 2 opening and colliding with the tool magazine compartment 1. It can also effectively alleviate the impact of a large force when closing the door, and play a role in buffering and limiting.

[0033] like Figure 3 As shown, the tool magazine compartment 1 of this embodiment has a closing groove 6 on both sides of the tool magazine door 2, and a magnetic attraction member 61 for attracting the tool magazine door 2 is provided in the closing groove 6. The tool magazine door 2 can be embedded in the closing groove 6 on both sides, and the magnetic attraction member 61 can ensure the sealing of the closing, avoid dust infiltration during the processing, and protect the tool from contamination. And the magnetic attraction member 61 can prevent the tool magazine door 2 from exposing a gap due to the vibration of the machine tool during operation.

[0034] In summary, the beneficial effects of this embodiment are as follows: this embodiment reduces the occupation of the external space of the machine tool by integrating the cylinder 32, the mounting seat 31 and the push rod 33 inside the tool magazine 1, and effectively avoids mutual interference with other parts of the machine tool. Then, by connecting the push rod 33 with the tool magazine door 2 and the rotating seat 34 in a rotating connection manner at both ends, the push rod 33 can be freely rotated in accordance with the rotation trajectory of the tool magazine door 2, ensuring smooth transmission during the opening and closing process, avoiding the jamming or additional lateral force that may be caused by the fixed connection, and improving the smooth opening and closing performance of the tool magazine door 2. A retaining edge 5 and a buffering limiter 51 at the bottom are set at the opening end of the tool magazine door 2 to limit the maximum opening angle of the tool magazine door 2, avoid occupying too much Z-axis space, and reduce the impact and noise during opening through the buffering effect. The magnetic suction member 61 set in the closing groove 6 provides additional adsorption force for the closing of the tool magazine door 2, and even slight vibration during the operation of the machine tool will not cause the door body to loosen or produce gaps, ensuring the sealing of the tool magazine, effectively isolating the intrusion of dust and cutting fluid, and protecting the tool.

[0035] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
