Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a disc-type tool magazine ejection device for a CNC machine tool. Background Technology

[0002] The robotic arm disc-type tool magazine is one of the core tool magazine types in CNC machining centers. It stores tools via a disc-shaped tool holder and, in conjunction with the robotic arm, enables rapid tool changes. It is widely used in high-precision machining fields such as automotive parts and precision molds. Its integrated design and efficient tool changing performance make it a key component for improving the machining efficiency and automation level of CNC equipment.

[0003] In CNC machine tool machining, tool changing is a crucial factor affecting machining efficiency and accuracy. Traditional tool magazines often employ chain-type or bucket-type designs. These designs result in slow tool changing speeds when dealing with a large number of tools, and their complex structures lead to high maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings mentioned in the background art by proposing a disc-type tool magazine ejection device for CNC machine tools.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A disc-type tool magazine ejection device for a CNC machine tool robotic arm includes a base plate. A fixed frame is fixedly connected to the right side of the upper surface of the base plate. Two guide rail plates are fixedly connected to the left side of the fixed frame. Guide grooves are formed on the outer surfaces of the two guide rail plates. Movable blocks are slidably connected to the inner walls of the two guide grooves. A movable frame is fixedly connected to the left side of the two movable blocks. A drive motor is fixedly connected to the front of the inner wall of the movable frame. A rotating plate is fixedly connected to the power output end of the drive motor. Ejection clamps are fixedly connected to both the front and rear sides of the rotating plate.

[0006] Preferably, a second drive motor is fixedly connected to the rear of the inner wall of the fixed frame, and a disc-type tool magazine is fixedly connected to the power output end of the second drive motor.

[0007] Preferably, a plurality of clamps are fixedly connected to the outer surface of the disc-shaped tool magazine, and the inner wall of the clamps is provided with a tool body.

[0008] Preferably, a fixing plate is fixedly connected to the rear of the inner wall of the fixed frame, an electric push rod is fixedly installed in front of the fixing plate, a drive rod is fixedly connected to the power output end of the electric push rod, a movable rod is fixedly connected to the front of the drive rod, and the front of the movable rod is fixedly connected to the rear of the fixing frame on the right side of the movable frame, and a support frame is fixedly connected to the lower surface of the electric push rod.

[0009] Preferably, a support frame is fixedly connected to the rear of the left side of the upper surface of the base plate, and a guide rail is fixedly connected to the upper surface of the support frame.

[0010] Preferably, a movable block is slidably connected to the right side of the guide rail, a cylinder is fixedly installed on the right side of the movable block, and an annular sleeve is fixedly connected to the right side of the cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes an electric push rod to drive a movable frame via a drive rod and a movable rod. The movable block, in conjunction with the guide groove of the guide rail plate, achieves smooth and rapid sliding, quickly pushing the ejection clamp to the corresponding tool position on the disc-type tool magazine. Simultaneously, the second drive motor rotates the tool magazine, quickly moving the target tool to the tool changing and waiting position. The combined effect significantly reduces the preparation time before tool ejection. Furthermore, the movable block on the guide rail, combined with a cylinder and an annular sleeve, can quickly adjust its position to receive or assist in transferring the ejected tool, reducing waiting time during tool transfer and thus reducing non-machining time on the machine tool, improving the overall machining cycle time. Furthermore, the entire tool ejection process requires no manual intervention. In multi-process machining, it can automatically eject and switch between different tools in sequence, meeting the needs of machining centers to complete multiple processes in one setup, and avoiding the tedious operations and time losses caused by manual tool changing.

A second drive motor 10 is fixedly connected to the rear of the inner wall of the fixed frame 2. A disc-type tool magazine disk 11 is fixedly connected to the power output end of the drive motor 10. The outer surface of the disc-type tool magazine disk 11 is fixedly connected to... There are several clamps 12. The inner wall of the clamp 12 is provided with a tool body 13.

The lower surface of the electric push rod 15 is fixedly connected to a support frame 18. The rear of the left side of the upper surface of the base plate 1 is fixedly connected to a receiving frame 19. The upper surface of the receiving frame 19 is fixedly connected to a guide rail 20. The right side of the guide rail 20 is slidably connected to a moving block 21. The right side of the moving block 21 is fixedly provided with a cylinder 22. The right side of the cylinder 22 is fixedly connected to an annular sleeve 23.

[0017] In CNC machine tool machining, tool changing is a crucial factor affecting machining efficiency and accuracy. Traditional tool magazines often employ chain-type or bucket-type designs. These designs result in slow tool changing speeds when dealing with a large number of tools, and their complex structures lead to high maintenance costs. When the operator uses the device, firstly, the clamps 12 firmly hold the corresponding tool bodies 13, the moving blocks 21 stop at the initial position on the left side of the guide rail 20, the cylinders 22 are in the retracted state, and the annular sleeves 23 are away from the tool magazine area. Then, the drive motor 10 starts, and its power output drives the disc-type tool magazine 11 to rotate around its own axis, accurately positioning the clamp 12 where the target tool body 13 is located, so that the tool rotates to the tool changing position corresponding to the ejection clamp 9. The drive motor 10 stops running and locks the tool magazine. The electric push rod 15 starts under the stable support of the support frame 18, and its power output pushes the drive rod 16 to extend forward. The drive rod 16 drives the movable rod 17 to move synchronously. The movable rod 17 pulls the moving frame 6, so that the moving frame 6 slides horizontally and linearly along the guide grooves 4 of the guide rail plate 3 through the movable blocks 5 on both sides, smoothly. The feed proceeds towards the disc-type tool magazine 11 until the ejection clamp 9 moves to the preset clamping positions on both sides of the target tool body 13. The electric push rod 15 stops feeding and maintains its current position. The ejection clamp 9 clamps the tool body 13 and smoothly pushes it away from the tool magazine until it moves to the preset receiving position. The moving block 21 on the guide rail 20 is activated and slides along the guide rail 20 in the tool ejection direction. The horizontal position of the cylinder 22 and the annular sleeve 23 is adjusted so that the annular sleeve 23 is coaxially aligned with the ejected tool body 13. The cylinder 22 is activated and pushes the annular sleeve 23 to extend in the tool direction until the annular sleeve 23 is fitted onto the left side of the tool body 13, pushing the tool body 13 from the inside of the clamp 12 into the inside of the ejection clamp 9. This can achieve a slight push on the tool, and the moving block 21 on the guide rail 20 can be driven by an external power source. Then the electric push rod 15 is started again, moving the tool body 13 away from the disc-type tool magazine 11. The drive motor 7 is started, and its power output end drives the rotating plate 8 to rotate 180 degrees. The push-out clamps 9 on the front and rear sides of the rotating plate 8 and the tool body 13 rotate synchronously in opposite directions, thereby completing the tool push-out operation.
