Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a device for protecting the bending motion of a drag chain on a machine tool magazine rotary platform. Background Technology

[0002] Currently, in a SORALUCE CNC machining center (FR-10000), the tool magazine's rotating axis causes the tool magazine's cable carrier to rotate around the axis on a cable carrier tray. During this rotation, uneven stress on the cable carrier joints easily leads to misalignment, causing the cable carrier to break, which in turn causes the internal cables to break, ultimately rendering the machine unusable. Even after replacing the cable carrier, the malfunction persists, further impacting machining quality and efficiency.

[0003] Therefore, we propose a protection mechanism for the bending motion of the cable chain on the rotating platform of a machine tool magazine, in order to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a protection mechanism for the bending motion of the drag chain on a machine tool magazine rotary platform, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable drag chain bending motion protection mechanism for a machine tool magazine rotating platform, comprising: a cable drag chain, a cable drag chain tray, a tool magazine robot rotating shaft, and a tool magazine tray support. The cable drag chain is movably mounted on the cable drag chain tray, and the cable drag chain tray is fixedly mounted on the tool magazine tray support. The tool magazine robot rotating shaft is disposed in the middle of the tool magazine tray support and movably passes through the cable drag chain tray. A telescopic spring is installed inside the cable drag chain, and the telescopic spring and the cable drag chain are fixed together by a flexible connector. One end of the cable drag chain is connected to the tool magazine robot rotating shaft, and the other end of the cable drag chain is connected to the edge of the cable drag chain tray.

[0006] Preferably, the cable drag chain tray is a circular tray structure, comprising a circular base and baffles circumferentially disposed on the top edge of the circular base.

[0007] Preferably, the height of the baffle is more than half the height of the cable drag chain.

[0008] Preferably, a circular through hole is provided at the center of the circular chassis, and the bottom of the rotating shaft of the tool magazine robot passes through the circular through hole of the cable drag chain tray and is rotatably connected to the tool magazine tray bracket.

[0009] Preferably, the shape and inner diameter of the circular through hole match the shape and outer diameter of the rotating shaft of the tool magazine robot.

[0010] Preferably, the inner wall of the baffle is connected to the other end of the cable drag chain.

[0011] Preferably, the flexible connector is made of nylon cable ties.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] During the reciprocating motion of the cable drag chain, it is constrained by the telescopic spring. The telescopic spring has a certain degree of contraction, which can maintain the integrity and continuity of the cable drag chain in the motion path, greatly extending the service life of the cable drag chain. It can ensure the accuracy of the machine tool magazine movement, and thus effectively solve the problem of frequent twisting and breakage of the tool magazine drag chain and cable breakage, greatly reducing the failure rate of the equipment. The device is easy to install and debug, simple, efficient and cost-effective. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a bending motion protection mechanism for a machine tool magazine rotating platform cable chain, comprising: a cable chain 1, a cable chain tray 2, a tool magazine manipulator rotating shaft 3, a telescopic spring 4, and a tool magazine tray bracket 5. The telescopic spring 4 is installed inside the cable chain 1, and the telescopic spring 4 and the cable chain 1 are fixed together by a flexible connector 6.

[0020] The cable drag chain tray 2 is a circular tray structure. The cable drag chain 1 is movably supported on the cable drag chain tray 2. The cable drag chain tray 2 includes a circular base 21 and a baffle 22 circumferentially set on the top edge of the circular base 21. The height of the baffle 22 is more than half the height of the cable drag chain 1 and is used to limit the cable drag chain 1. A circular through hole is opened at the center of the circular base 21 for installing the tool magazine robot rotating shaft 3. Its shape and inner diameter match the shape and outer diameter of the tool magazine robot rotating shaft 3. The tool magazine robot rotating shaft 3 and the cable drag chain tray 2 are fixed together by bolts.

[0021] One end of the cable drag chain 1 is connected to the rotating shaft 3 of the tool magazine robot, and the other side of the cable drag chain 1 is fixedly connected to the inner wall of the baffle 22. The bottom of the rotating shaft 3 of the tool magazine robot passes through the circular through hole of the cable drag chain tray 2 and is rotatably connected to the tool magazine tray bracket 5. The cable drag chain 1 performs bending motion on the upper surface of the cable drag chain tray 2 by the rotation of the rotating shaft 3 of the tool magazine robot.

[0022] The function of the telescopic spring 4 is to bear the bending stress when the cable drag chain 1 is bending. When the device is in use, the telescopic spring 4 should be fixed inside the cable drag chain 1. There are no special requirements for the position and number of fixing points, as long as they do not interfere with the operation of the cable drag chain 1. At the same time, it should be noted that the space occupied by the cable inside the cable drag chain 1 should not be too large, and in principle, it should be less than 60%.

[0023] In this embodiment, the diameter of the circular base 21 of the cable drag chain tray 2 is about 750 mm and the circumference is about 2300 mm. The diameter of the circular through hole in the center and the rotating shaft 3 of the tool magazine robot are about 200 mm and the circumference is about 600 mm.

[0024] In this embodiment, the cable drag chain 1 is also provided with a flexible connector 6. The flexible connector 6 binds and fixes the telescopic spring 4 to the outer cover plate of the cable drag chain 1. The flexible connector 6 is made of nylon cable ties or the like.

[0025] like Figure 3 The paper lists three different extreme angle states of the cable drag chain 1 during rotation. After testing, the cable drag chain 1 worked stably and well in these three angle states. After 12 months of verification, no friction or bending of the drag chain was observed.

[0026] The rotating shaft 3 of the tool magazine robot rotates, pulling the cable drag chain 1 to move within the cable drag chain tray 2. During the reciprocating motion of the cable drag chain 1, it is constrained by the telescopic spring 4. The telescopic spring 4 has a certain degree of contraction, which can maintain the integrity and continuity of the cable drag chain 1 in the movement path, greatly enhancing the service life of the cable drag chain 1 and ensuring the accuracy of the machine tool tool magazine movement. This effectively solves the problem of frequent twisting and breaking of the tool magazine drag chain and cable breakage, greatly reducing the failure rate of the equipment. The device is easy to install and debug, simple, efficient and cost-effective.

[0027] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
