Description

Technical Field

[0001] The invention relates to the technical field of disc tool magazines in machining centers, in particular to a disc tool magazine tool reversing device and a disc tool magazine. Background Art

[0002] In the disc tool magazine of the machining center, multiple tool sleeves are evenly arranged along the circumference of the tool disc. The tool sleeves are used to install tools. The tool disc is rotated to select tools. The tool sleeve is pushed down by the reverse tool cylinder group to reverse the tool, so that the tool sleeve flips down, and then the tool change operation is performed. After the tool change is completed, the tool sleeve is pulled back and flipped up and reset by the reverse tool cylinder group to collect the tool. Because the tool sleeve is equipped with a tool, the tool sleeve will easily flip down under the load of the tool and the tool sleeve itself, and the tool disc cannot rotate when the tool sleeve flips down. If the machine tool system gives the tool magazine an instruction to rotate the tool disc, the tool magazine will definitely be damaged. Therefore, after the tool is collected, the tool sleeve needs to be locked, so the self-locking of the reverse tool cylinder needs to be realized, and it must withstand a certain load. When the reverse tool instruction is not received, the self-locking of the reverse tool cylinder prevents the tool sleeve from flipping down easily to protect the tool magazine.

[0003] The knife-reversing cylinder realizes linear reciprocating motion through two air intake ports. The air intake at the upper port of the cylinder pushes the knife sleeve down to realize knife reversing, and the air intake at the lower port flips the knife sleeve up and retracts the knife. In order to realize the self-locking of the knife-reversing cylinder, the conventional practice is to add a check valve at the lower port of the cylinder. After the cylinder retracts and the knife is retracted, the air in the lower chamber of the cylinder cannot flow back, making the cylinder self-locking. However, since the cylinder itself may leak, the cylinder locking is unreliable, and if used for a long time, the impurities and water vapor contained in the compressed air will block and corrode the air port of the check valve, affecting the normal use of the cylinder and reducing its service life.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Embodiment 1

[0031] like Figures 1-2 and Figures 6-7 As shown, the present embodiment provides a disc tool magazine tool flipping device, comprising a tool flipping cylinder 1, a tool flipping support block 2, a self-locking female buckle 3 and a self-locking male buckle 4, the tool flipping support block 2 is fixedly connected to the end of the piston rod 5 of the tool flipping cylinder 1, and the piston rod 5 can be extended and retracted to enable the tool flipping support block 2 to move up and down, the self-locking female buckle 3 is fixedly connected to the end face of the front end cover of the tool flipping cylinder 1, and the self-locking male buckle 4 is fixedly connected to the tool flipping support block 2, and the upward movement of the tool flipping support block 2 can drive the tool sleeve 22 to flip upward to achieve tool retraction and make the self-locking male buckle 4 engage with the self-locking female buckle 3 to lock the tool sleeve 22, and the downward movement of the tool flipping support block 2 can separate the self-locking male buckle 4 from the self-locking female buckle 3 to unlock and drive the tool sleeve 22 to flip downward to achieve tool flipping.

[0032] In the disc tool magazine, a plurality of tool sleeves 22 are evenly arranged along the circumference of the tool disc, a front cover 23 of the tool magazine is arranged outside the circumference formed by the plurality of tool sleeves 22, a tool sleeve flipping opening 24 is arranged at the bottom end of the front cover 23 of the tool magazine, and a tool sleeve flipping device of the disc tool magazine is located just above the tool sleeve flipping opening 24. When the tool needs to be flipped, the piston rod 5 of the tool flipping cylinder 1 extends out to push the tool flipping support block 2 to move downward, and the tool flipping support block 2 moves downward to separate and unlock the self-locking male buckle 4 from the self-locking female buckle 3 and drive the tool sleeve 22 to flip downward along the tool sleeve flipping opening 24 to realize the tool flipping; when the tool needs to be collected, the tool flipping cylinder 1 pushes the piston rod 5 of the tool flipping cylinder 1 ... The piston rod 5 of the cylinder 1 retracts and drives the reverse tool support block 2 to move upward. The upward movement of the reverse tool support block 2 drives the tool sleeve 22 to flip upward from the tool sleeve flipping opening 24 to achieve the knife collection and make the self-locking male buckle 4 engage with the self-locking female buckle 3 to achieve the locking of the tool sleeve 22. The locking is safe and reliable, avoiding the situation that the tool sleeve 22 flips down when the machine tool system instructs the tool disc to rotate, protecting the disc tool magazine, and at the same time, avoiding the disadvantages of unreliable locking using a traditional check valve, and will not affect the normal use of the reverse tool cylinder due to blockage and corrosion of the check valve, thereby improving the service life of the reverse tool cylinder.

[0033] like Figure 1 and Figures 3 to 5 As shown, the self-locking female buckle 3 includes a self-locking block 6, a self-locking ball 7, an elastic element 8 and a pressure plate 9. The self-locking block 6 is fixedly connected to the end surface of the front cover of the inverted knife cylinder 1. A locking hole 10 is provided on the bottom surface of the self-locking block 6. The axis of the locking hole 10 is parallel to the axis of the piston rod 5. A slide hole 11 is provided on the side of the self-locking block 6. The slide hole 11 is connected to the locking hole 10. The self-locking ball 7 and the elastic element 8 are both arranged in the slide hole 11. The elastic element 8 squeezes the self-locking ball 7 at one end of the slide hole 11 connected to the locking hole 10 and makes the self-locking ball 7 protrude from the inner wall of the locking hole 10. The slide hole 11 is connected to the locking hole 10 One end of the self-locking ball 7 can limit the self-locking ball 7 so that the self-locking ball 7 cannot slide out of the slide hole 11, the pressure plate 9 is fixedly connected to the side of the self-locking block 6 and squeezes the elastic element 8 into the slide hole 11; the self-locking male buckle 4 includes a self-locking rod 12 and a connecting part 13, the self-locking rod 12 is fixedly connected to the connecting part 13, the connecting part 13 is fixedly connected to the inverted knife support block 2, the axis of the self-locking rod 12 is colinear with the axis of the locking hole 10, and a limiting groove 14 is provided on the self-locking rod 12.
