Technical Field

[0001] The utility model relates to the technical field of numerical control machining centers, in particular to a linear end driven machine tool magazine. Background Art

[0002] In the automatic tool change magazine configured in the CNC machining center, it is generally necessary to drive the chain of the tool clamp module to rotate through a motor. In the prior art, the motor drives the chain to move through the gear and chain structure, thereby driving the tool clamp module to move. Since the teeth of the output gear used are relatively weak, it is generally necessary to increase the number of teeth that are meshed at the same time to ensure that the output torque is sufficient to drive the chain machine tool clamp module to move. Therefore, in the prior art, the motor is generally set at the turning point of the chain structure of the tool clamp module, which makes it difficult to adjust the setting position of the motor, and other mechanisms or structures are required to circumvent the position of the motor, which causes great trouble in the design of the overall equipment. At the same time, since the setting position of the motor is fixed, and during installation, the motor and gear are generally installed first, and then the chain is put on the gear, therefore, there is great inconvenience when installing the chain.

[0003] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a machine tool magazine with a linear end drive.

[0005] The technical solution of the utility model is as follows: a linear end driven machine tool tool magazine is provided, comprising: a tool magazine body, a motor arranged on the tool magazine body, an output gear arranged on the output end of the motor, and a driving chain sleeved on the edge of the tool magazine body, the output gear adopts a wide tooth type in which the width of the gear teeth is greater than the gap between the teeth, the chain links of the driving chain are provided with driving holes corresponding to the gear teeth of the output gear, the gear teeth of the output gear are movably engaged in the driving hole, the motor drives the output gear to rotate, and pushes the inner wall of the driving hole through the gear teeth to drive the chain to move.

[0006] Furthermore, the tooth pitch of the output gear is 90-110 mm.

[0007] Furthermore, the meshing position of the output gear and the chain link of the driving chain is arranged at a position corresponding to the straight line segment of the tool magazine body.

[0008] Furthermore, a movable groove is provided on the tool magazine body corresponding to the motor, a movable mounting plate is movably provided in the movable groove, and the motor is arranged on the movable mounting plate.

[0009] Furthermore, the tool magazine body is provided with a sliding track or a sliding groove corresponding to the movable mounting plate, and the movable mounting plate moves along the sliding track or the sliding groove.

[0010] Furthermore, a plurality of limit plates are arranged on the movable groove at sides corresponding to the movable mounting plate.

[0011] Furthermore, an auxiliary motor is arranged on the tool magazine body, an output gear is arranged on the output end of the auxiliary motor, and the auxiliary motor is arranged on a side away from the motor.

[0012] By adopting the above scheme, the utility model adopts a wide-tooth output gear, and meshes the output gear with the chain link of the drive chain to increase the structural strength of the gear teeth and increase the torque, so that when the chain link is pushed, the chain link can be effectively driven, thereby realizing the movement of the tool clamp module set on the chain link. Since the driving effect on the chain link is more stable, the motor can be set at any edge position on the tool magazine body to achieve the driving effect on the chain link, so that the motor can be adjusted according to the setting position of different mechanisms, avoiding interference with other mechanisms and improving the freedom of the motor setting position.

[0015] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] See also Figure 1 , Figure 2The utility model provides a linear end driven machine tool magazine, comprising: a magazine body 1, a motor 2 arranged on the magazine body 1, an output gear 3 arranged on the output end of the motor 2, and a drive chain sleeved on the edge of the magazine body 1, wherein the output gear 3 adopts a wide tooth profile in which the width of the gear teeth 31 is greater than the gap 32 between the teeth, and the chain link 41 of the drive chain 4 is provided with a drive hole corresponding to the gear teeth 31 of the output gear 3, and the gear teeth 31 of the output gear 3 are movably engaged in the drive hole, and the motor 2 drives the output gear 3 to rotate, and pushes the inner wall of the drive hole through the gear teeth 31 to drive the chain 41 to move. By adopting a wide tooth output gear 3, and meshing the output gear 3 with the chain link 41 of the drive chain 4, the structural strength at the gear teeth 31 is increased, and the torque is increased, so that when the chain link 41 is pushed, the chain link 41 can be effectively driven, thereby realizing the movement of the tool clamp module arranged on the chain link 41. Since the driving effect on the chain link 41 is more stable, the motor 2 can be set at any edge position on the tool magazine body 1 to achieve the driving effect on the chain link 41, so that the motor 2 can be adjusted according to the setting position of different mechanisms to avoid interference with other mechanisms and improve the freedom of the setting position of the motor 2.

[0017] The pitch of the output gear 3 is 90-110 mm. Preferably, in some embodiments, the pitch of the output gear 3 and the pitch between adjacent connections 41 are both 100 mm, so as to ensure that a safe distance is set between adjacent tool holder modules, while satisfying the transportation of the tool holder modules, avoiding mutual interference or collision between the tool holder modules, and meeting the safety requirements during the tool change process.

[0018] In some embodiments, the meshing position of the output gear 3 and the chain link 41 of the driving chain 4 is set at the position corresponding to the straight section of the tool magazine body 1. By setting the meshing position of the output gear 3 and the chain link 41 at the straight section of the tool magazine body 1, while satisfying the driving of the chain link 41, since the number of chain links 41 meshing at the same time is small, during the installation process, the chain link 41 is more convenient to be sleeved on the output gear 3, thereby improving the installation and debugging efficiency of the overall equipment.

[0019] In some embodiments, a movable groove 11 is provided on the tool magazine body 1 corresponding to the motor 2, a movable mounting plate 5 is movably provided in the movable groove 11, and the motor 2 is provided on the movable mounting plate 5. By providing a movable movable mounting plate 5 and arranging the motor 2 on the movable mounting plate 5, during installation or maintenance, the position of the movable mounting plate 5 can be moved to separate or mesh the output gear 3 and the chain link 41, thereby improving the efficiency of assembly and disassembly during installation and maintenance.

[0020] In some embodiments, the tool magazine body 1 is provided with a sliding track or a sliding groove corresponding to the movable mounting plate 5, and the movable mounting plate 5 moves along the sliding track or the sliding groove, so that when the position of the motor 2 needs to be adjusted or moved during installation and maintenance, a guiding function can be provided, thereby improving the accuracy of the moving position of the movable mounting plate 5 and the motor 2.

[0021] In some embodiments, a plurality of limit plates are provided on the movable groove 11 corresponding to the side of the movable mounting plate 5. The limit plates are used to limit and fix the side surfaces of the movable mounting plate 5, thereby fixing the movable mounting plate 5, thereby ensuring that the movable mounting plate 5 will not shift during operation, thereby preventing the output gear 4 of the motor 3 from being separated from or offset from the links of the drive chain 42, and ensuring the stability of the overall device during operation.

[0022] In some embodiments, the tool magazine body 2 is provided with an auxiliary motor 32, an output gear 4 is provided on the output end of the auxiliary motor 32, and the auxiliary motor 42 is provided on a side away from the motor. When the motor 2 exerts force on the chain link 41 through the output gear to move the drive chain 4, the output gear 3 of the auxiliary motor 2 can synchronously exert force on the chain link 41, thereby playing an auxiliary driving role, reducing the load applied to the motor 2, so that more chain links 41 and / or tool holder modules can be added to the device.

[0023] In summary, the utility model adopts a wide-tooth output gear, and meshes the output gear with the chain link of the drive chain to increase the structural strength of the gear teeth and increase the torque, so that when the chain link is pushed, the chain link can be effectively driven, thereby realizing the movement of the tool clamp module set on the chain link. Since the driving effect on the chain link is more stable, the motor can be set at any edge position on the tool magazine body to achieve the driving effect on the chain link, so that the motor can be adjusted according to the setting position of different mechanisms, avoiding interference with other mechanisms and improving the freedom of the motor setting position.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
