Description

Technical Field

[0001] This utility model belongs to the field of loading and unloading tools technology, specifically relating to a quick loading and unloading machine for intelligent CNC milling cutters. Background Technology

[0002] When using machining centers or CNC milling machines, it is often necessary to install, remove, or replace cutting tools. Since the cutting tool is fixed to the tool holder by a lock nut and spring collet, the lock nut must be removed before the tool and spring collet can be taken off for replacement. The lock nut has a positioning groove, which facilitates positioning and rotating the lock nut using a disassembly tool. Currently, the method for installing and removing the lock nut is to first fix the milling cutter holder to the tool remover, and then manually remove it using a semi-circular four-jaw wrench. During disassembly, one of the jaws on the wrench is used for positioning, and the wrench is turned to rotate the lock nut. However, since the wrench jaws and the limiting grooves of the lock nut are not one-to-one, positioning by the wrench jaws has drawbacks such as inconvenience, easy misalignment, and low work efficiency. Furthermore, once the jaws are stuck in the positioning groove on the lock nut, it is difficult to remove the wrench. In addition, after prolonged use, the connection between the lock nut and the tool holder becomes very firm, often making it impossible to disassemble with a wrench. Therefore, the existing technology needs improvement.

[0003] Chinese patent CN213889849U, published on August 6, 2021, discloses a milling cutter assembly / disassembly device. The device includes a base with guide rails, a fixed seat mounted on the base, and a drive mechanism. It also includes a disassembly / assembly workpiece connected to the drive mechanism. The fixed seat is used to fix the milling cutter shank. The milling cutter shank, the connecting shaft, and the output shaft of the drive mechanism are all horizontally coaxial. The drive mechanism and the disassembly / assembly workpiece are used to assemble / disassemble the locking nut on the milling cutter shank. However, this patent lacks the ability to adjust the locking force of the tool according to the machining requirements of the cutter diameter and the material being processed, and to achieve torque adjustment through stepper motor torque monitoring and control.

[0004] To address the problems of existing technologies, this utility model provides a quick assembly and disassembly machine for intelligent CNC milling cutters. The tool holder assembly is used to clamp the tool and drive the tool to rotate. The wrench assembly and the tool holder assembly work together to tighten or loosen the tool nut. A diffuse reflection infrared photoelectric switch is used to detect whether the tool is in place. After the parameters are set in the controller, the quick assembly and disassembly machine can be automatically controlled.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A quick-release machine for intelligent CNC milling cutters includes a support frame and a controller. The support frame, from top to bottom, is equipped with a wrench assembly, a diffuse infrared photoelectric switch, and a tool holder assembly. The wrench assembly and the tool holder assembly cooperate to tighten or loosen the tool nut. The tool holder assembly moves up and down under the drive of a first longitudinal moving mechanism. The tool holder assembly includes a tool holder fixing sleeve for clamping the tool. The lower end of the tool holder fixing sleeve is connected to a stepper motor via a first coupling. The tool holder fixing sleeve is connected to a tool holder mounting frame via a bearing cap and a tapered roller bearing. The tool holder mounting frame is connected to the first longitudinal moving mechanism, which drives the tool holder assembly to move up and down. The diffuse infrared photoelectric switch is used to detect the tool height and whether the tool groove is in position. The controller is connected to the first longitudinal moving mechanism and the stepper motor.

[0007] Preferably, the wrench assembly includes a wrench holder and a socket wrench, wherein the wrench holder is connected to a support frame and the wrench holder is connected to the socket wrench.

[0008] Preferably, the support frame is mounted on the frame cabinet.

[0009] Preferably, the first longitudinal moving mechanism includes a tool moving motor, which is connected to the support frame via a motor mounting base. The tool moving motor is connected to a lead screw via a second coupling. A slider is slidably mounted on the lead screw, and the slider is connected to the tool holder. A lead screw fixing seat is also provided at the end of the lead screw away from the second coupling, and the lead screw fixing seat is connected to the frame cabinet.

[0010] Preferably, the slider is slidably mounted on the tool holder guide rail, and both ends of the tool holder guide rail are connected to the support frame through lead screw fixing seats.

[0011] Preferably, the wrench holder is further provided with a second longitudinal moving component for driving the wrench assembly to move up and down.

[0016] The beneficial effects of this technical solution are as follows:

[0017] I. This utility model provides a quick assembly and disassembly machine for intelligent CNC milling cutters. The cutter is fixed on the tool holder retaining sleeve. Under the control of the controller, the first longitudinal moving mechanism moves the tool holder assembly upward. When the diffuse infrared photoelectric switch detects that the cutter is in position, it sends information to the controller. The controller controls the stepper motor to rotate slowly. When the tool groove on the cutter is sensed by the infrared photoelectric switch, the controller controls the stepper motor to stop rotating. At this time, the tool groove on the cutter is aligned with the inner teeth of the upper socket wrench. The cutter moving motor starts, moving the cutter upward to engage the tool groove with the inner teeth of the socket wrench. At this time, the stepper motor starts. Under the dual action of the cutter moving motor and the stepper motor, the cutter nut is tightened. After tightening, the controller controls the stepper motor to stop rotating, and the cutter moving motor drives the tool holder assembly back to its position. The cutter assembly and tightening are complete. Throughout the process, the tightening force of the cutter is matched with the diameter of the cutter, which is set in the controller. The motor torque is monitored in real time during the tightening process. The machine can automatically stop working if the tool groove and the inner teeth of the socket wrench are not aligned or if there is any misalignment. When disassembling the tool, the tool slot and the inner teeth of the socket wrench are aligned under the action of the diffuse reflection infrared photoelectric switch. The tool moving motor feeds the tool into the socket wrench to engage. The stepper motor reverses, and at the same time, the tool moving motor reverses as well, causing the tool to move downwards. The tool nut is unscrewed. After unscrewing, the stepper motor stops rotating, the tool holder assembly returns to its initial position, the electric push rod retracts, and the socket wrench moves upwards, leaving space for the tool to be removed.

[0019] III. The present invention provides a quick loading and unloading machine for intelligent CNC milling cutters. The tool sleeve is designed for convenient tool storage. The horizontal adjustment wheel can meet the requirements of rapid movement and ensure the stability of the device. Attached Figure Description

[0040] I. This utility model provides a quick assembly and disassembly machine for intelligent CNC milling cutters. The cutter 5 is fixed on the tool holder fixing sleeve 6.

The machine can automatically stop working when the tool slot 25 and the inner teeth of the socket wrench 23 are not aligned or are misaligned. When disassembling the tool 5, the tool slot 25 and the inner teeth of the socket wrench 23 are aligned under the action of the diffuse reflection infrared photoelectric switch 24. The tool moving motor 13 sends the tool 5 into the socket wrench 23 for engagement.
