Description

Technical Field

[0001] The present application relates to the technical field of ultra-precision cutting equipment, and in particular to an ultra-precision cutting micro-lubrication cooling system and method. Background Art

[0002] During ultra-precision cutting, in order to improve the surface finish of the workpiece, cutting fluid is continuously sprayed on the contact position between the tool and the workpiece to reduce the friction and temperature in the contact area between the tool and the workpiece, avoid surface defects such as pitting, pits, cracks, and surface / sub-surface damage on the surface of the workpiece caused by severe friction and high temperature, and at the same time reduce tool wear.

[0003] For single crystal silicon materials, ultra-precision cutting is usually performed by heating the processing area to about 400°C through laser. The reason is that single crystal silicon is a brittle material at room temperature. At about 400°C, it will change from brittle to plastic, which can improve cutting performance. However, due to the heating effect of the laser, the rigidity of the tool will decrease. Therefore, cutting fluid needs to be continuously sprayed during the processing to reduce cutting heat and reduce tool wear. However, if too much cutting fluid is sprayed, the effect of laser heating single crystal silicon will not be ideal. If too little cutting fluid is sprayed, the effect of reducing cutting heat will not be obvious.

[0004] For materials such as single crystal germanium, the material is usually removed directly through traditional ultra-precision cutting processing. During the processing, in order to reduce the friction and temperature between the tool and the workpiece, it is usually necessary to spray cutting fluid. The traditional cutting fluid spraying method is usually to continuously spray lubricating fluid to the cutting area through a fixed nozzle. Although this method reduces the thermal damage during the cutting process to a certain extent, the large-scale use of cutting fluid also causes many negative effects, not only causing air pollution, but also bringing potential harm to the ecological environment and human health.

[0005] Based on the above-mentioned problem that it is impossible to determine and control the amount of cutting fluid used, in the process of laser heating-assisted ultra-precision cutting, spraying too much cutting fluid will cause unsatisfactory laser heating effect, and spraying too little cutting fluid will not reduce cutting heat and cause tool wear; in the process of traditional ultra-precision cutting, too much cutting fluid will cause environmental pollution, and spraying too little cutting fluid will lead to insufficient lubrication and local high temperature in the contact area between the tool and the workpiece, causing damage to the processed surface. The present invention provides an ultra-precision cutting micro-lubrication cooling system and method. Summary of the invention

[0048] In order to reduce the amount of cutting fluid used in the ultra-precision cutting process, the present application provides an ultra-precision cutting micro-lubrication cooling system.

[0049] See also Figure 1 and Fig.10 The ultra-precision cutting micro-lubrication cooling system described in the present application includes a tool holder 1, a thermal camera 2, a cutting fluid guide pipe 3, a cutting fluid nozzle 4, a first angle adjustment electric telescopic rod 5, a second angle adjustment electric telescopic rod 6, a display screen 7, a controller 8, and a flow control valve 11;

[0050] The tool seat 1 is a part of the processing machine tool. The tool seat 1 is provided with a mounting seat 9 extending vertically upward. The mounting seat 9 is mounted on the tool seat 1. A ball head hole is constructed on the mounting seat 9. One end of the cutting fluid guide tube 3 is provided with a ball head matching the ball head hole. The ball head is embedded in the ball head hole to form a ball head joint, thereby movably connecting one end of the cutting fluid guide tube 3 with the mounting seat 9. At the same time, the end of the cutting fluid guide tube 3 connected to the mounting seat 9 is also connected to a supply system 10 for providing cutting fluid through a pipeline. The other end of the cutting fluid guide tube 3 is installed with a cutting fluid nozzle 4. A flow control valve 11 is provided on the connecting pipeline between the cutting fluid guide tube 3 and the supply system 10.

[0051] During the ultra-precision cutting process, the supply system 10 delivers the cutting fluid to the cutting fluid guide pipe 3, and then sprays the cutting fluid to the machining position of the workpiece through the cutting fluid nozzle 4 to achieve the effect of cooling and lubricating the workpiece machining surface, thereby reducing the damage to the workpiece surface and increasing the service life of the tool.

[0052] One end of the first angle-adjustable electric telescopic rod 5 is movably connected to the middle of the mounting seat 9 through a ball joint, and the other end is movably connected to the cutting fluid guide tube 3 through a ball joint; one end of the second angle-adjustable electric telescopic rod 6 is movably connected to the bottom of the mounting seat 9 through a ball joint, and the other end is movably connected to the cutting fluid guide tube 3 through a ball joint; when both telescopic rods are not extended, the first angle-adjustable electric telescopic rod 5 is roughly located on a horizontal plane, and the second angle-adjustable electric telescopic rod 6 is roughly located on a vertical plane. Therefore, when in use, the extension of the first angle-adjustable electric telescopic rod 5 and the second angle-adjustable electric telescopic rod 6 can be controlled to drive one end of the cutting fluid guide tube 3 having the cutting fluid nozzle 4 to move up, down, left and right, thereby adjusting the liquid outlet angle of the cutting fluid nozzle 4, and then adjusting the position where the cutting fluid is mainly cooled, that is, the center position of the cutting fluid spray.

[0053] A thermal camera 2 is provided on the mounting seat 9, and the thermal camera 2 is used to detect the temperature of the workpiece and the tool to obtain the temperatures of different positions of the workpiece and the tool. A display screen 7 is provided on the rear side of the thermal camera 2; the thermal camera 2 is electrically connected to the signal input end of the controller 8, and the signal output end of the controller 8 is electrically connected to the first angle adjustment electric telescopic rod 5, the second angle adjustment electric telescopic rod 6, the display screen 7, and the flow control valve 11 respectively.

[0054] During the ultra-precision cutting process, the thermal camera 2 detects the temperature of different positions of the workpiece and the tool and transmits it to the controller 8. The controller 8 determines the high-temperature area based on the input information, and then controls the first angle adjustment electric telescopic rod 5 and the second angle adjustment electric telescopic rod 6 to work, and adjusts the outlet angle of the cutting fluid nozzle 4 so that the center of the cutting fluid spray can face the high-temperature area, so that only less cutting fluid is needed to meet the cooling needs of the workpiece and the tool, thereby reducing the amount of cutting fluid used, and further reducing the cost of ultra-precision cutting. At the same time, the controller 8 adjusts the pressure of the cutting fluid injection through the opening size of the flow control valve 11 to ensure that enough cutting fluid can be injected into the processing area to ensure that the cooling and lubrication of the processing position meet the requirements.

[0055] In this embodiment, if Figure 2 As shown, the supply system 10 includes a cutting fluid storage barrel 1001, a pressure pump 1002, and an overflow valve 1003 which are connected in sequence; the liquid outlet end of the overflow valve 1003 is connected to the flow control valve 11 through a pipeline, and the overflow port of the overflow valve 1003 is connected to the cutting fluid storage barrel 1001 through a pipeline. During use, continuous coolant is provided by the pressure pump 1002, and a constant supply pressure is provided by the overflow valve 1003 to avoid the problem of pipe burst due to excessive pressure.

[0056] Furthermore, in this embodiment, the supply system 10 also includes a high-pressure gas supply device 1004. The high-pressure gas supply device 1004 can be an air compressor, a high-pressure gas supply pump or other equipment.

[0057] like Figure 3 As shown, the cutting fluid nozzle 4 includes an air inlet pipe 401 and an atomizing nozzle 402; the air inlet pipe 401 is provided with an atomizing nozzle 402, the nozzle direction of the atomizing nozzle 402 blows into the air inlet pipe 401, the atomizing nozzle 402 is connected to the flow control valve 11 through a pipeline, and the air inlet pipe 401 is connected to the high-pressure air supply equipment 1004 through a pipeline.

[0058] During operation, the high-pressure air supply device 1004 introduces high-pressure air into the air inlet pipe 401, and the cutting fluid is dispersed into mist through the atomizing nozzle 402 and sprayed into the air inlet pipe 401. Then, the mist cutting fluid is blown toward the high-temperature area of ​​the workpiece under the influence of the high-pressure air. The high-temperature area is cooled down at the same time by the high-speed airflow and cutting fluid. In this way, the use of cutting fluid is further reduced.

[0059] Furthermore, in this embodiment, if Figure 4 As shown, a flow rate enhancement component 403 is provided in the air inlet pipe 401. The flow rate enhancement component 403 is tubular, and is contracted in the middle and expanded at both ends. When the high-speed flowing cutting fluid and high-pressure air mixture passes through the flow rate enhancement component 403, it is compressed in the middle position of the flow rate enhancement component 403, and then expands outward, thereby greatly improving the flow speed of the mixture, thereby effectively improving the cooling effect of the mixture. At the same time, the mist-like cutting fluid can be dispersed more finely after the compression and expansion process, effectively improving its cooling and lubrication effects.

[0060] Furthermore, in this embodiment, if Figure 5 and Figure 6 As shown, the flow rate enhancement member 403 includes a support frame 404 and an elastic rubber body 405; the support frame 404 is mounted on the outer side of the elastic rubber body 405 to maintain the basic shape of the elastic rubber body 405, that is, a structure with large ends and a contracted middle.

[0061] The support frame 404 includes an end frame 4041, a connecting rod 4042, and a retaining plate 4043; there are two end frames 4041, which are arranged parallel to each other, and the two end frames 4041 are connected as a whole through the connecting rod 4042; one end of the retaining plate 4043 is fixedly connected to the end frame 4041, and the other end extends inwardly at an angle, and the retaining plates 4043 are arranged at intervals along the circumferential direction of the end frame 4041.

[0062] Furthermore, in this embodiment, the retaining sheet 4043 is made of an elastic steel sheet and has a tendency to bend inwards, and the two ends of the elastic rubber body 405 are tightened, so that the middle part thereof has a tendency to expand outwards. A flow rate regulating rope 406 is wound around the middle part of the outer side surface of the elastic rubber body 405, and the flow rate regulating rope 406 is wound around the elastic rubber body 405 at least once, and one end of the flow rate regulating rope 406 is fixedly connected to the connecting rod 4042, and the other end passes through the pipe wall of the air inlet pipe 401 and then extends outwards.

[0063] During use, the outwardly extending end of the flow rate regulating rope 406 can be pulled to tighten the flow rate regulating rope 406 , thereby increasing the shrinkage of the middle part of the elastic rubber body 405 , thereby adjusting the flow rate of the mixture sprayed from the cutting fluid nozzle 4 .

[0064] Furthermore, in this embodiment, if Figure 7 and Figure 8 As shown, a flow rate adjustment telescopic rod 407 is provided on the outer wall of the air inlet pipe 401, and the flow rate adjustment telescopic rod 407 is extended along the length direction of the air inlet pipe 401. The telescopic end of the flow rate adjustment telescopic rod 407 is fixedly connected to the flow rate adjustment rope 406. When the flow rate adjustment telescopic rod 407 is shortened, the flow rate adjustment rope 406 is pulled out more, and the contraction amount of the middle part of the elastic rubber body 405 increases. On the contrary, when the flow rate adjustment telescopic rod 407 is extended, the contraction amount of the middle part of the elastic rubber body 405 decreases. The flow rate adjustment telescopic rod 407 can be electrically connected to the signal input end of the controller 8, and the flow rate adjustment telescopic rod 407 is controlled by the controller 8 to improve the control accuracy of the flow rate adjustment telescopic rod 407.

[0065] Furthermore, in the present embodiment, an injection area adjusting member 408 is also provided at the air outlet end of the air inlet pipe 401; the injection area adjusting member 408 comprises a C-shaped end support ring 4081, an extended support rod 4082, and an elastic rubber sleeve 4083, and a groove matching the shape of the end support ring 4081 is constructed on the inner wall of the air inlet pipe 401, and the end support ring 4081 is embedded in the groove, thereby fixing the injection area adjusting member 408 to the air inlet pipe 401. Extension support rods 4082 are arranged at intervals around the circumference of the end support ring 4081 on one side close to the air outlet end of the air inlet pipe 401, and an elastic rubber sleeve 4083 is sleeved on the outer side of the extension support rod 4082. A nozzle adjustment rope 409 is wrapped around the end of the elastic rubber sleeve 4083. The nozzle adjustment rope 409 is wrapped around the end of the elastic rubber sleeve 4083. One end of the nozzle adjustment rope 409 is fixedly connected to the inner wall of the air inlet pipe 401, and the other end extends outward after passing through the side wall of the air inlet pipe 401. When the nozzle adjustment rope 409 is pulled outward, the nozzle adjustment rope 409 is tightened, and the end of the elastic rubber sleeve 4083 is reduced, so that the cross-section of the ejected air flow column becomes smaller.

[0066] During operation, the size of the cross-section of the jet air column can be adjusted so that high-speed airflow and cutting fluid can be concentratedly sprayed to the high-temperature area to achieve precise cooling, thereby effectively reducing the use of cutting fluid.

[0067] Further, in this embodiment, a nozzle adjustment telescopic rod 410 is provided on the outer side wall of the air inlet pipe 401, and the telescopic end of the nozzle adjustment telescopic rod 410 is fixedly connected to the nozzle adjustment rope 409. When the nozzle adjustment telescopic rod 410 is short, the nozzle adjustment rope 409 is pulled out more, the end of the elastic rubber sleeve 4083 is contracted, and the cross section of the ejected air column becomes smaller. On the contrary, when the nozzle adjustment telescopic rod 410 is extended, the end of the elastic rubber sleeve 4083 rebounds and expands under the action of the extension support rod 4082, and the cross section of the ejected air column becomes larger. The nozzle adjustment telescopic rod 410 can be electrically connected to the signal input end of the controller 8, and the nozzle adjustment telescopic rod 410 is controlled by the controller 8 to improve the control accuracy of the nozzle adjustment telescopic rod 410.

[0068] In some embodiments, Fig. 9 As shown, a sleeve 411 is provided on the outside of the air inlet pipe 401, and a spray cleaning chamber 412 is provided between the sleeve 411 and the air inlet pipe 401. The spray cleaning chamber 412 is connected to the high-pressure air supply device 1004 through a pipeline, and the left end of the spray cleaning chamber 412 is closed and the right end is open. When working, the high-pressure air supply device 1004 introduces high-pressure air into the spray cleaning chamber 412, and then sprays it from the right side, forming a high-speed air flow layer on the outside of the spray sprayed from the air inlet pipe 401, which has the following functions: 1. Reduce the influence of external airflow on the air column sprayed from the air inlet pipe 401, so that the air column sprayed from the air inlet pipe 401 can be accurately sprayed to the designated area; 2. Blow out the excess cutting fluid in the processed part of the workpiece to avoid the influence of excess cutting fluid on the processed area.

[0069] The present application also provides an ultra-precision cutting micro-lubrication cooling method. Based on any of the above embodiments, the ultra-precision cutting micro-lubrication cooling method is:

[0070] The thermal camera 2 collects the temperature of the workpiece surface in real time.
