Compared with the prior art, the beneficial effects of the present invention are:

1. The metal processing machine tool capable of automatic tool change is provided with gears, gear rings, turntables, hydraulic devices, push rods, movable sleeves and buffer blocks. The motor rotates the gears, and the meshing of the gears and gear rings drives the turntable to rotate, so as to select different cutter heads for processing. After selecting a suitable cutter head, the hydraulic device pushes the push rod, so that the connecting block is inserted into the connecting groove. The push rod continuously pushes the movable sleeve to move downward in the protective sleeve and compresses the first spring, so as to push the cutter head out of the cutting edge. The whole tool changing process does not require the cutter head to be disassembled, thus saving processing time. After the cutter head is used, the first spring rebounds to push the cutter head into the protective sleeve, so as to protect the cutter head.

2. The metal processing machine tool capable of automatic tool changing is provided with a fixed rod, a clamping block, a torsion spring, a buffer block, a clamping joint and a clamping slot. When the push rod pushes the buffer block to compress the second spring, the buffer block will push the clamping block to rotate on the fixed rod and twist the torsion spring. As the push rod continues to move, the clamping block will be stuck in the clamping slot, thereby locking the clamping joint, so that the push rod can push the tool head to move more stably. By compressing the second spring through the buffer block, buffering can be performed when the clamping joint contacts the buffer block, thereby avoiding damage to the clamping joint caused by the impact force generated by sudden contact.

DETAILED DESCRIPTION

The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

As shown in Fig. 1-4, the utility model provides a technical solution: a metal processing machine tool capable of automatically changing tools, comprising a workbench 1, guide rails 2 are connected to both sides of the workbench 1, a moving column 3 is installed on the guide rail 2, a lifting beam 4 is installed on the moving column 3, a moving platform 5 is installed on the lifting beam 4, a tool changing platform 6 is connected below the moving platform 5, a hydraulic pressure 7 is installed on the tool changing platform 6, a push rod 15 is connected below the hydraulic pressure 7, one end of the push rod 15 is connected to a card joint 16, a card slot 17 is provided on the card joint 16, and a card joint 16 is connected below the card joint 16. A connecting block 18 is connected, a motor 8 is installed under the tool changing platform 6, a connecting rod 9 is connected under the tool changing platform 6, a turntable 10 is rotatably connected to the connecting rod 9, a gear ring 11 is installed on the turntable 10, a knife outlet 12 is opened under the turntable 10, and a plurality of protective sleeves 13 are installed on the turntable 10. Through the engagement of the connecting block 18 and the connecting groove 26, the card joint 16 can be quickly positioned, and the motor 8 rotates the gear 14 to drive the turntable 10 to rotate, so that the staff can quickly complete the replacement of the tool, thereby improving the processing efficiency.

The output shaft of the motor 8 is connected to a gear 14, which is meshed with the ring gear 11. Slide rods 19 are connected to both sides of the protective sleeve 13. A limit plate 20 is connected inside the protective sleeve 13. A first spring 21 is connected to the limit plate 20. One end of the first spring 21 is connected to a movable sleeve 22. Ear plates 23 are connected to both sides of the movable sleeve 22. A cutter head 31 is connected below the movable sleeve 22. The ear plates 23 are slidably connected to the slide rod 19. The movable sleeve 22 moves along the slide rod 19 through the ear plates 23, so that the movable sleeve 22 can move smoothly, thereby preventing the movable sleeve 22 from tilting and causing the cutter head 31 to be skewed, thereby avoiding damage to the cutter head 31.

A second spring 24 is connected to the inside of the movable sleeve 22, and a buffer block 25 is connected to one end of the second spring 24. The buffer block 25 is of conical design and is provided with a connecting groove 26. The connecting groove 26 is engaged with the connecting block 18. The conical buffer block 25 can push the card block 29 to rotate when the buffer block 25 moves downward. At the same time, the buffer block 25 will compress the second spring 24 to buffer the impact force when the card joint 16 contacts the buffer block 25, thereby avoiding damage to the card joint 16 caused by direct contact.

A groove 27 is provided inside the movable sleeve 22, and a fixing rod 28 is connected inside the groove 27. A block 29 is rotatably connected to the fixing rod 28. Torsion springs 30 are connected on both sides of the block 29. One end of the torsion spring 30 is connected to the inner wall of the groove 27. The block 29 is L-shaped and one end is triangular. The triangular end of the block 29 is engaged with the slot 17, and the block 29 is fitted with the outer wall of the buffer block 25. The L-shaped block 29 makes it easier for the buffer block 25 to push the block 29 to rotate. Multiple blocks 29 in the movable sleeve 22 are simultaneously inserted into the slot 17, so that the block 29 fixes the card joint 16 more firmly.

The working principle of the utility model is:

The starting motor 8 rotates the gear 14, and the gear 14 will drive the gear ring 11 to make the turntable 10 start to rotate, so as to select different cutter heads 31 for processing. After selecting the appropriate cutter head 31, the hydraulic pressure 7 will push the push rod 15. As the push rod 15 continues to move, the connecting block 18 will be stuck in the connecting groove 26, so as to position the card joint 16, and the buffer block 25 will move downward to compress the second spring 24. At the same time, the conical buffer block 25 will push the card block 29 to rotate on the fixed rod 28, so that the card block 29 can be stuck in the card groove 17, thereby locking the card joint 16 to prevent the card joint 16 from loosening. After that, the movable sleeve 22 will also be pushed by the push rod 15, so that the movable sleeve 22 compresses the first spring 21 downward, so as to push the cutter head 31 out of the cutting edge 12. After the cutter head 31 is used, the hydraulic pressure 7 retracts the push rod 15, so that the first spring 21 rebounds and pushes the movable sleeve 22 to move upward, so that the cutter head 31 re-enters the protective sleeve 13 to prevent the cutter head 31 from being damaged.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
