Description

Technical Field

[0001] The present application relates to the technical field of CNC machine tools, and in particular to a spindle anti-collision alarm device for CNC machine tools. Background Art

[0002] During the normal operation of the CNC machine tool, the sensor monitors the position and speed of the spindle in real time and transmits the data to the controller. The controller analyzes and processes the data through a preset algorithm to determine whether the spindle may collide. If it is determined that there is a risk of collision, the controller will send an alarm signal to the alarm. After receiving the signal, the alarm will immediately sound an alarm to prompt the operator to take timely measures to avoid collision.

[0003] A Chinese patent publication (publication number: CN213437212U) discloses a CNC machine tool spindle, including a box mechanism, bearing mechanisms are fixedly installed on both sides of the box mechanism, a shaft body is inserted inside the bearing mechanism, the box mechanism includes a mounting box, a hole groove, a positioning hole and a threaded hole, and both ends of the mounting box are provided with a hole groove. The utility model has the advantages that the bearing mechanism is fixed on both sides of the mounting box by bolts, so that during the high-speed rotation of the shaft body, displacement will not occur due to the vibration of the equipment, the structure is reliable, and the practicality is improved. When installing the bearing mechanism, after the positioning shaft is inserted into the positioning hole, the through hole on the mounting plate can be aligned with the threaded hole on the mounting box, which facilitates the fixing of the bolts, reduces the number of bolts used, and achieves the purpose of easy disassembly and assembly. The protrusion is plugged into the positioning groove to avoid the inner ring of the bearing failing to rotate synchronously with the shaft body due to the high-speed rotation of the shaft body, resulting in wear on the outer surface of the shaft body.

[0004] When CNC machine tools process wood, a large amount of dust will be generated. If fine particles of dust adhere to the bell mouth of the alarm for a long time, the dust will block the propagation path of the sound, restricting the propagation of the sound and causing the alarm sound to become smaller, thereby reducing the intensity of the sound. In addition, the dust may also cause physical damage to the bell mouth of the alarm. Utility Model Content

[0069] Secondly, the fixed frame 5 will isolate the dust through the protective net 6 to prevent dust from entering the bell mouth of the sound alarm 4. When the protective net 6 needs to be disassembled and cleaned regularly, the handheld handle 7 can drive the protective net 6 inside the fixed frame 5 to move. At this time, when the protective net 6 is displaced, the No. 2 card block 10 on one side of the telescopic plate 9 is driven to move through the No. 1 card block 8 on one side.

[0070] Finally, when the protective net 6 is displaced, the protective net 6 is cleaned by the cleaning brushes 15 on both sides to achieve the cleaning of the protective net 6. When the cleaning brush 15 needs to be cleaned later, the cleaning brush 15 is driven to vertically displace inside the "C"-shaped groove 11. At this time, the cleaning brush 15 is no longer squeezed by the spring 14 on one side of the extrusion plate 13 to achieve extrusion and fixing work.
