Technical Field

[0001] This utility model relates to the field of computer numerical control technology, specifically to an anti-collision device for a CNC machining center that is easy to disassemble. Background Technology

[0002] A CNC machining center is a computer numerical control (CNC) machine tool equipped with an automatic tool changer and tool magazine. It is a device that can perform multi-process automatic machining. To prevent tool collisions during machining, sensors are usually used for detection to achieve collision avoidance.

[0003] Currently, whether programming is done manually or automatically by computer, it is impossible to completely eliminate tool collisions. Once a collision occurs, it can damage the tool or parts, or even damage the machine itself, which must be avoided.

[0004] To address the aforementioned technical issues, CN107479500B discloses a CNC system and method for motion positioning of a machining center with a vision device. By introducing a vision detection device and adding image processing, pre-path collision prediction, and safety / hazard interlocking processes to the original workflow, the system achieves the effect of predicting and preventing collisions, greatly improving the safety and stability of the machining center, and also enhancing the intelligence of the machining center.

[0005] The aforementioned prior art also has the following shortcomings: in actual use, the anti-collision device is not easy to disassemble. Due to long-term use, it needs to be disassembled, maintained, repaired, or replaced. Therefore, due to the complex installation method, it is impossible to achieve quick disassembly and assembly, which reduces the efficiency of disassembly and assembly. Utility Model Content

[0031] 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.

[0032] This utility model provides an anti-collision device for CNC machining centers that is easy to disassemble, including a spindle 1;

[0033] A connecting mechanism 2 for assisting disassembly and assembly is provided on one side of the spindle 1, a support mechanism 3 for anti-collision is provided on one side of the connecting mechanism 2, and a fixing mechanism 4 for quick disassembly and assembly is provided inside the support mechanism 3.

[0034] Fixed mechanism 4 includes;

[0035] An elastic component is disposed inside the support mechanism 3. The inner end of the elastic component is provided with a snap-fit ​​component and a rotating component adapted to the snap-fit ​​component. An auxiliary component is disposed on the outer side of the rotating component.

[0036] Preferred;

[0037] like Figure 2 As shown, the connecting mechanism 2 includes;

[0038] The connecting seat 21 is bolted to one side of the main shaft 1. A first through hole 22 and a mounting groove 23 corresponding to the first through hole 22 are provided on one side of the connecting seat 21. The connecting seat 21 is used to adapt to the connecting parts by providing the first through hole 22 and the mounting groove 23 when installing the anti-collision device, thereby achieving the purpose of installation.

[0039] in;

[0040] like Figure 3 As shown, the support mechanism 3 includes;

[0041] The support box 31 is attached to one side of the connecting seat 21. A second through hole 32 is opened on one side of the support box 31. The vibration acceleration sensor body 33 is fixedly installed at the bottom of the support box 31. The support box 31 is used to install the vibration acceleration sensor body 33 and can also be used to install the fixing mechanism 4.

[0042] It is worth explaining;

[0043] like Figure 4 As shown, the elastic component includes;

[0044] The telescopic rod 41 is fixedly installed on the top and bottom surfaces of the inner cavity of the support box 31. The top and bottom surfaces of the inner cavity of the support box 31 are also fixedly installed with springs 42 located on the outside of the telescopic rod 41. The cooperation between the telescopic rod 41 and the springs 42 can realize vertical elastic telescopic operation, thereby assisting in installation and disassembly operations.

[0045] Going a step further;

[0046] like Figure 4 As shown, the snap-fit ​​assembly includes;

[0047] The connecting plate 43 is fixedly installed on the inner end of the telescopic rod 41 and the spring 42. A clamping plate 44 is fixedly installed on one end of the connecting plate 43. The connecting plate 43 and the clamping plate 44 can be installed and disassembled during the pushing and pulling process.

[0048] in addition;

[0049] like Figure 4 As shown, the rotating assembly includes;

[0050] The rotating shaft 46 is rotatably connected to one side of the support box 31. A rotating block 47 is fixedly installed at one end of the rotating shaft 46. The rotating shaft 46 can change the angle of the rotating block 47 by rotational force, thereby realizing the installation and disassembly operations.

[0051] at last;

[0052] like Figure 4As shown, the auxiliary components include;

[0053] The connecting sleeve 45 is fixedly installed on the inner side wall of the support box 31. The connecting sleeve 45 is rotatably connected to the outer side of the rotating shaft 46. The other end of the rotating shaft 46 is fixedly installed with a handle 48. The connecting sleeve 45 can increase the support for the rotating shaft 46, while the handle 48 facilitates the rotation of the rotating shaft 46.

[0054] As shown in the figure, this is the installed state. When disassembly is required, simply hold the handle 48 and rotate it. During the rotation, the rotating shaft 46 and the rotating block 47 connected to it will rotate together until the rotating block 47 changes from a vertical state to a horizontal state. During this process, the compressed telescopic rod 41 and spring 42 are released, and the corresponding connecting plate 43 will be pushed to move. At the same time, it will move inward to shorten the distance between the upper and lower connecting plates 43. Then, the locking plate 44 will move inside the mounting groove 23 and contact the locking installation state until the two sets of connecting plates 43 contact the rotating block 47, which is in a horizontal state after rotation. At this time, simply pull the support box 31 outward, and the locking plate 44 will disengage from the mounting groove 23 to complete the disassembly. This method of disassembly is simple and improves the efficiency of disassembly.

[0055] When installation is required, simply reverse the disassembly process described above. As shown above, in the disassembly state, hold the support box 31 to drive the card plate 44 through the first through hole 22 and insert it into the installation slot 23 until it can no longer be inserted. At this time, rotate the rotating block 47 by rotating the handle 48 to change it from a horizontal to a vertical state. During this rotation, the upper and lower connecting plates 43 will be pushed and the telescopic rod 41 and spring 42 will be squeezed. Then, the card plate 44 will move inside the installation slot 23 until it can no longer move upward and is tightly locked and fixed to complete the installation operation.

[0056] 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.
