Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, specifically a chip removal device for CNC machining of precision structural parts. Background Technology

[0002] Precision structural components refer to parts or assemblies manufactured through high-precision machining processes, with strict requirements for dimensional tolerances, geometric tolerances, and surface quality. They are widely used in fields with extremely high requirements for precision, reliability, and functionality. CNC machining is a key process in the manufacturing of precision structural components. It uses digital programming to control the movement of machine tools to achieve high-precision cutting, milling, drilling, and other operations on materials such as metals and plastics.

[0003] A search revealed that patent application number 202421266759.X discloses a metal chip removal device for a CNC machining center. The top of the chip removal box has a chip discharge port for discharging metal chips generated by the machining device into the chip removal box. The chip removal box has a storage chamber for collecting coolant. The chip removal device includes a chip removal component disposed in the chip removal box for filtering metal chips, and a drive component is disposed above the chip removal component for driving the chip removal component to vibrate up and down.

[0004] Although the chip removal device of this CNC machining center uses a motor to drive a cam and connecting plate to vibrate intermittently under the elastic force of a spring, which quickly collects metal chips from the filter plate into the slag collection box and allows coolant to flow into the storage chamber, a dynamic gap is created between the bottom of the filter plate and the slag collection box during the up-and-down vibration. This gap provides a channel for metal chip leakage, causing chips that should have been retained in the slag collection box to enter the storage chamber. Over time, the metal chips mixed in with the storage chamber not only contaminate the circulating fluid but also lead to quality problems such as accelerated tool wear and workpiece surface scratches in subsequent machining processes.

[0005] Therefore, we propose a chip removal device for CNC machining of precision structural parts. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a chip removal device for CNC machining of precision structural parts. It solves the problem that gaps will form between the bottom slag storage boxes of the filter plate during the up-and-down vibration of the existing device, allowing metal chips to enter the interior of the liquid storage chamber through the gaps, resulting in poor separation of metal chips.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a chip removal device for CNC machining of precision structural parts, including a chip removal box disposed below the machining device body for machining the workpiece, a liquid storage chamber for collecting coolant is provided in the box cavity of the chip removal box, and a chip removal port is provided in the middle of the top surface of the chip removal box.

[0008] The slag discharge box is equipped with a slag discharge assembly, which includes an agitation component. A collection box is located below the slag discharge box.

[0009] The slag discharge assembly includes an annular cover fixedly installed on the top of the inner wall of the slag discharge box and connected to the slag discharge port. A filter bucket is fixedly installed on the bottom surface of the annular cover. The filter bucket has evenly distributed filter holes on the side wall at the top. A second valve is installed on the bottom of the filter holes. The bottom of the second valve penetrates the bottom surface of the slag discharge box and extends to the top of the collection box.

[0010] Preferably, a drain pipe is fixedly installed at the bottom of the front side of the slag discharge box, and a first valve is installed on the drain pipe. Both the drain pipe and the second valve are solenoid valves.

[0011] Preferably, the agitation assembly includes a motor, a shaft, and an agitator rod. The motor is fixedly installed at the bottom end of the side wall of the annular cover. The output end of the motor passes through the side wall of the annular cover and is fixedly connected to the shaft. The end of the shaft away from the motor is rotatably installed on the inner wall of the annular cover through a bearing. The shaft is rotated by the motor.

[0012] Preferably, agitators are fixedly installed on the outer surface of the middle part of the shaft, wherein when the shaft rotates, it can drive the agitators to rotate together, thereby agitating the metal debris inside the filter bucket.

[0013] Preferably, support plates are fixedly installed on both the left and right sides of the bottom surface of the slag discharge box. A sliding groove is opened on the side of the support plate facing the middle of the slag discharge box. Sliding blocks that are slidably fitted inside the sliding groove are fixedly installed on the left and right side walls of the collection box. This is to limit the collection box to the bottom of the slag discharge box and collect the metal debris discharged from the bottom of the filter hopper through the collection box.

[0014] This utility model provides a chip removal device for CNC machining of precision structural parts. It has the following features:

[0015] Beneficial effects:

[0016] This chip removal device for CNC machining of precision structural parts uses a slag removal component and an agitation component to separate metal chips and coolant, facilitating the removal of metal chips. Metal chips and coolant enter the annular cover and filter hopper through the slag removal port. The coolant then flows through the filter holes into the storage chamber, while the metal chips remain inside the filter hopper. The coolant entering the storage chamber is discharged through the drain pipe, and the metal chips inside the filter hopper are discharged into the collection box through the bottom of the hopper. During this process, a motor drives an agitator to stir the metal chips inside the filter hopper, facilitating their removal. This improves the separation effect of metal chips and coolant, preventing metal chips from mixing into the separated coolant. It solves the problem in existing devices where gaps form between the filter plates and the bottom slag storage box during up-and-down vibration, allowing metal chips to enter the storage chamber and resulting in poor metal chip separation.
