Description

Technical Field

[0001] This invention belongs to the field of precision special machining technology, and in particular relates to a high-precision turning machining auxiliary device and its usage method. Background Technology

[0002] Turning, with its advantages of high efficiency, high surface quality, and high flexibility, plays an irreplaceable role in the manufacturing of key components for high-end equipment such as aerospace and electronic information. However, in the turning of difficult-to-machine materials such as high-temperature alloys, metal-based materials, and ceramic-based composite materials, the high hardness and brittleness of the materials, coupled with the close contact between the tool face and the chip, make it difficult for external cutting fluid to enter the edge area of ​​the friction pair contact interface under conventional cooling methods. This hinders the lubrication effect, leading to problems such as rapid tool wear, poor surface quality, and low machining accuracy. This significantly restricts the precision, quality, and efficiency of machining key components for high-end equipment. Therefore, how to efficiently introduce cutting fluid into the friction pair contact interface to improve lubrication and reduce cutting temperature, thereby achieving low-wear, high-precision, high-quality, and high-efficiency machining of key components for high-end equipment, is an urgent problem to be solved. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a device and method that can efficiently introduce cutting fluid at the contact interface of friction pairs, improve the lubrication effect and reduce the cutting temperature, and realize low-wear, high-precision, high-quality and high-efficiency machining of key components of high-end equipment.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: a high-precision turning machining auxiliary device, comprising a micro-lubrication and cooling module, a cavitation cooling ultrasonic cleaning and vibration cutting module, a three-axis motion module and a spindle module.

[0005] The micro-lubrication and cooling module includes an ultrasonic oil reservoir support, a first piezoelectric transducer, an ultrasonic oil reservoir device, and a micron-level nozzle. For example... Figure 2As shown, the ultrasonic oil reservoir support is an L-shaped bracket. The upper part of the ultrasonic oil reservoir support is used for detachable and fixed connection of the first piezoelectric transducer and the ultrasonic oil reservoir device. The bottom end of the ultrasonic oil reservoir support is fixedly connected to the base plate. There is an ultrasonic oil reservoir on the left side of the ultrasonic oil reservoir device, which is used to store lubricating oil. The ultrasonic oil reservoir is filled with oil through the filling hole and has a device to display the amount of oil. The ultrasonic oil reservoir is sealed with a diaphragm. The outer side of the diaphragm is in contact with the right end vibration device of the first piezoelectric transducer. The surface of the diaphragm is larger than the cross-section of the vibration device of the first piezoelectric transducer. The high-frequency vibration energy of the first piezoelectric transducer causes a change in the volume inside the ultrasonic oil reservoir. Under the impact of the high-frequency vibration energy, the lubricating oil forms micron-sized droplets and detaches from the surface of the lubricating oil to form atomization. The ultrasonic oil reservoir is fixedly connected to a micron-sized nozzle through a thin tube. The atomized lubricating oil is sprayed out through the micron-sized nozzle. The micron-sized nozzle is located near the rake face of the microtextured PCD tool, thereby forming a small amount of cooling and lubrication on the rake face of the microtextured PCD tool.

[0006] The cavitation-cooled ultrasonic cleaning and vibration cutting module includes: a pressure tank, a hydraulic tank, a second piezoelectric transducer, a microchannel structure ultrasonic tool holder, and a microtextured PCD tool. Excluding the pressure tank and hydraulic tank, the other components of the cavitation-cooled ultrasonic cleaning and vibration cutting module are located below the micro-lubrication cooling module. The microchannel structure ultrasonic tool holder includes a cylindrical portion and an L-shaped portion, such as... Figure 3 As shown, the L-shaped portion is located at the top of the vertical side of the cylindrical portion, and the upper surfaces of both are flush. The second piezoelectric transducer is vertically fixedly mounted on the base plate, which is fixedly connected to the slider of the X-axis slide. The second piezoelectric transducer is fixedly connected to the bottom surface of the cylindrical part of the microchannel structure ultrasonic scalpel holder via a screw. The screw is surrounded by piezoelectric ceramics and copper sheets, which convert electrical energy into mechanical energy. The L-shaped part of the microchannel structure ultrasonic scalpel holder is detachably and fixedly mounted with a microtextured PCD tool. The microtextured PCD tool is located at the farthest corner of the L-shaped part from the cylindrical part. The upper part of the cylindrical part of the microchannel structure ultrasonic scalpel holder has a microchannel. The L-shaped part of the microchannel structure ultrasonic scalpel holder contains a flow guiding structure. The microchannel is horizontal, and the flow guiding structure is an inclined fine channel. One end of the microchannel is connected to the hydraulic tank via a pipe with a one-way valve. The other end of the microchannel is sealed to the top of the flow guiding structure. The bottom end of the flow guiding structure is located near the microtextured structure of the microtextured PCD tool. The microtextured structure of the microtextured PCD tool is located near the microtextured PCD tool. At one corner of the rake face of the tool, the microtexture structure consists of multiple regularly arranged regular octagonal grooves. The microtexture PCD tool is located near the micron-level nozzle.

[0007] Preferably, the inclination angle of the flow guiding structure is 5° to 10°.

[0008] Preferably, the octagonal groove has a side length of 15μm to 20μm and a depth of 40μm to 80μm.

[0009] Preferably, the number of rows of the octagonal grooves is 3 to 8, and the number of columns of the octagonal grooves is 10 to 35.

[0010] The three-axis motion module includes an X-axis slide, a Y-axis slide, a Z-axis slide, and a marble gantry. The X-axis slide is fixedly connected to the slider of the Z-axis slide. The X-axis slide can move along the Z-axis with the slider of the Z-axis slide, and the slider of the X-axis slide can move along the X-axis. In this way, the micro-textured PCD tool can move along the X-axis and Z-axis directions.

[0011] The spindle module includes a spindle fixture and a turning spindle, such as... Figure 1 As shown, the workpiece to be processed is detachably and fixedly mounted on the center of the turning spindle. The turning spindle can rotate around the central axis, thereby rotating the workpiece to be processed. The turning spindle is fixed on the slider of the Y-axis slide table by the spindle fixture. The Y-axis slide table is fixed on the marble gantry, which provides support and fixation. Thus, the workpiece to be processed is moved along the Y-axis direction by controlling the Y-axis slide table.

[0012] The present invention also provides a method for using a high-precision turning machining auxiliary device, the steps of which are as follows: S1: First check if the equipment is working properly, then install the microtextured PCD tool and the part to be processed.

[0013] S2: (1) Select oil-based cutting fluid for cooling First turn on the first piezoelectric transducer, then turn on the second piezoelectric transducer, and then start the processing program; Choose water-based cutting fluid for cooling. First, open the one-way valve, then open the pressure tank and set an appropriate air pressure value to control the micro-jet, so that a water film can be formed on the rake face of the micro-textured PCD tool. Then, turn on the second piezoelectric transducer, and finally start the machining program. After machining is completed, first close the pressure tank, and then close the first and second piezoelectric transducers.

[0014] Through the above design scheme, the present invention can bring the following beneficial effects: Water-based cutting fluid cooling can form a water film on the tool surface, and under the action of high-frequency vibration, a cavitation effect is formed. During the process of cavitation bubble collapse, the tool is cooled and ultrasonically cleaned, which effectively reduces cutting temperature and tool wear, while inhibiting the generation of built-up edge, improving tool life and part machining accuracy. By utilizing oil-based cutting fluid for cooling, the volume change of the ultrasonic oil reservoir under high-frequency vibration promotes the generation and collapse of cavitation bubbles in the lubricating oil, forming micro-jet or atomization. Finally, micro-cooling and lubrication of the tool are achieved through micron-level nozzles. At the same time, the high-frequency vibration of the tool generates low pressure during the separation of the tool and the chip, which promotes the flow of micro-oil droplets towards the cutting edge, further reducing tool wear and cutting temperature. It also increases the contact area of ​​the lubricating oil and the thickness of the oil film between the tool and the chip, reduces the coefficient of friction and friction time, increases the cooling and lubrication effect and the utilization rate of micro-lubrication of the lubricating oil, and improves the service life of the tool. (3) The device of the present invention has a simple structure and is easy to operate. It can realize the real-time switching between water-cooled cleaning and micro-oil-cooled lubrication, which greatly improves the processing efficiency of hard and brittle material parts.
