Description

Technical Field

[0001] The utility model relates to the technical field of machining centers, and particularly relates to a rotary tool magazine for a machining center. Background Art

[0002] A rotary tool magazine is a commonly used automatic tool changing device in machining centers. The tool magazine system is a device that provides the tool storage and tool changing requirements during the automated machining process. Its automatic tool changing mechanism and tool magazine that can store multiple tools have changed the traditional human-based production method. Through the control of computer programs, various different machining requirements, such as milling, drilling, boring, tapping, etc., can be completed, greatly shortening the machining time and reducing the production cost. This is the biggest feature of the tool magazine system.

[0003] For example, a disk-type rotary tool magazine for a machining center that is easy to use, with the publication (announcement) number of CN217572003U, relates to the technical field of machining centers; it solves the problems that currently, when rotating and adjusting the tool magazine, the rotation difficulty is greatly increased, the rotation efficiency is low, and the large tapered bearing will have a certain amount of wear during use, and it is difficult to meet the requirements for high-precision machining during rotation, etc.

[0004] To sum up, it can be seen that the following technical problems exist in the prior art: In the above prior art, the tool in the tool mounting seat is pushed out by the knife-reversing cylinder, and the second motor and the grasping manipulator are used to clamp and fix the pushed-out tool and perform rotary tool changing. During the entire tool changing process, we found that since the grasping manipulator can only clamp and change the tool pushed out by the knife-reversing cylinder through its own clamping movement and the rotational movement of the second motor, the tool pushed out by the knife-reversing cylinder should be completely separated from the tool mounting seat before subsequent tool changing operations can be carried out. Since the push block controlled by the knife-reversing cylinder does not have the function of adsorbing and clamping the tool, and the tool changing position of the tool is directly below the rotary tool magazine, the tool pushed out by the knife-reversing cylinder will freely fall due to the action of its own gravity when it is completely separated from the tool mounting seat. If the grasping manipulator cannot timely grasp and fix the tool, the tool will fall to the bottom of the machining center and cause unnecessary damage. Moreover, the grasping manipulator and the tool will also have wear during multiple tool changes. After the clamping and fixing positions of the grasping manipulator and the tool are worn, it will also affect the accuracy of the grasping manipulator in grasping the tool, resulting in an unstable entire tool changing process and poor actual use effect of the device.

[0005] Therefore, we designed a rotary tool magazine for a machining center to provide another technical solution for the above technical problems. Summary of the Utility Model

[0035] Refer to Figures 4-5 , the arc-shaped conveying assembly includes a suction conveying block 30 slidably clamped inside the mounting groove 6. A magnetic adsorption groove 31 for sucking the tool 5 and matching with the end of the tool 5 is provided in the middle of the suction conveying block 30. Arc-shaped clamping blocks 32 are fixedly connected to both sides of the suction conveying block 30. A plurality of second balls 33 are rotatably connected to both sides of the arc-shaped clamping blocks 32. An arc-shaped clamping groove 34 matching with the arc-shaped clamping blocks 32 and the second balls 33 is provided in the mounting groove 6. A plurality of stop buttons 35 are fixedly arranged inside the mounting groove 6.

[0036] It should be noted that in the present utility model, two stop buttons 35 are provided and are both electrically connected to the driving motor 38. Through this design, when the suction conveying block 30 moves to a specified position, the driving motor 38 can be stopped by pressing the stop button 35 through the column-shaped pressing block 36, thereby ensuring the accuracy of the moving position of the suction conveying block 30 and improving the practical performance of the device.

[0037] Refer to Figure 4, the gripping and tool changing assembly includes a rotary motor 39 fixedly arranged on one side of the assembly body 1. An installation groove three 40 facilitating the installation of the rotary motor 39 is provided on the assembly body 1. The output end of the rotary motor 39 is fixedly connected with a rotating disc two 41. A plurality of balls three 42 are rotatably connected to the circumferential side of the rotating disc two 41.

Specifically, in the present utility model, through the design of the rotary motor 39, the rotating disc two 41, the balls three 42 and the annular clamping groove two 43, the horizontal rotation of the gripping manipulator 45 is realized, so that the gripping manipulator 45 can replace the tool 5 transported by the arc-shaped conveying assembly with the tool 5 on the fixed chuck 3. Through the design of the balls three 42, the movement resistance during the rotation of the rotating disc two 41 is reduced, and the practicability of the device is improved. Through the design of the pneumatic cylinder two 44, the radial position movement of the gripping manipulator 45 is realized, so that the gripping manipulator 45 can remove the tool 5 clamped in the fixed chuck 3 and the magnetic adsorption groove 31, and complete the replacement of the tool 5 in cooperation with the rotational movement of the gripping manipulator 45.

[0038] The using process of a rotary tool magazine for a machining center provided by the present utility model is as follows:

[0039] First, the operator inputs the serial number of the tool 5 to be replaced on the control panel, then controls the servo motor 18 to start, and drives the tool mounting seat 2 to rotate through the cooperative transmission between the reducer 17, the second gear 15, the toothed belt 16, the first gear 14, the driving gear 11 and the annular rack 7, so that the tool 5 to be replaced on the tool mounting seat 2 is parallel to the arc-shaped electromagnetic clamp 29. Then, the servo motor 18 stops, and the first driving motor 23 starts and drives the adjusting screw 22 to rotate, so that the strip-shaped mounting block 21 threadedly connected to the adjusting screw 22 translates towards the tool 5 to be replaced. When the arc-shaped electromagnetic clamp 29 on the strip-shaped mounting block 21 completely sleeves the outside of the tool 5, the first driving motor 23 stops, the arc-shaped electromagnetic clamp 29 is energized to adsorb and clamp the tool 5, and then the first electric cylinder 27 starts to drive the arc-shaped electromagnetic clamp 29 to contract inward, so that the tool 5 disengages from the tool mounting seat 2. When the tool 5 is completely disengaged from the tool mounting seat 2, the first electric cylinder 27 stops, the first driving motor 23 starts, and drives the tool 5 to translate towards the suction conveying block 30. When the strip-shaped mounting block 21 moves to the limit position in the L-shaped mounting block 20, the first driving motor 23 stops. At this time, the end of the tool 5 is aligned with the magnetic adsorption groove 31 on the suction conveying block 30. Then, the first electric cylinder 27 starts, and drives the tool 5 on the arc-shaped electromagnetic clamp 29 to insert into the magnetic adsorption groove 31. When the end of the tool 5 abuts against the magnetic adsorption groove 31, the arc-shaped electromagnetic clamp 29 is de-energized, and the first electric cylinder 27 drives the arc-shaped electromagnetic clamp 29 to contract. At this time, the tool 5 is adsorbed in the magnetic adsorption groove 31. Then, the second driving motor 38 starts, and drives the suction conveying block 30 to perform an arc-shaped movement in the second mounting groove 6. When the cylindrical pressing block 36 at the bottom of the suction conveying block 30 presses the stop button 35 in the second mounting groove 6, the second driving motor 38 stops. At this time, the suction conveying block 30 is closely attached to the inner wall of the second mounting groove 6. Then, control the rotating motor 39 to rotate the grasping manipulator 45 by 90 degrees, and grasp and clamp the tool 5 to be replaced and the replaced tool 5. Then, the second electric cylinder 44 starts, and drives the grasping manipulator 45 to move downward, and takes the two tools 5 off the suction conveying block 30 and the fixed chuck 3 respectively. The second electric cylinder 44 stops. Then, control the rotating motor 39 to rotate the grasping manipulator 45 by 180 degrees, and then the second electric cylinder 44 starts to drive the grasping manipulator 45 to move upward, and inserts the tools 5 into the fixed chuck 3 and the suction conveying block 3 respectively. Then, the grasping manipulator 45 releases the clamping of the tools 5. Then, start the rotating motor 39 to drive the grasping manipulator 45 to rotate 90 degrees to reset. At this time, the replaced tool 5 is fixedly arranged in the tool mounting seat 2 through the cooperation of the arc-shaped conveying component, the clamping and disassembling component and the rotating component, and the replacement of the tool 5 can be completed.
