Description

Technical Field

[0001] The present invention belongs to the technical field of lathe machining, and particularly relates to a turret lathe for intelligent machining of pipe valve parts. Background Art

[0002] A numerically controlled lathe is a common one for cutting and machining the inner and outer cylindrical surfaces of shaft parts or disc parts, the inner and outer conical surfaces with any cone angle, complex revolving inner and outer curved surfaces, and cylindrical and conical threads, etc. By following a pre-programmed machining program, it automatically processes the machined parts, and through the numerically controlled lathe, high-quality and high-efficiency machining production work can be carried out on pipe valve part pipe workpieces.

[0003] For example, a cutting fluid cooling and filtering device for a numerically controlled lathe with the patent application number CN214634645U, which has good filtering and cooling effects by arranging a mesh filter layer, a sponge filter layer, and a cooling layer layer by layer, and a coolant pipe is circuitously arranged on the lower surface of the cooling disc 7, playing a good role in cooling and temperature reduction.

[0004] However, the above comparative document has the following defects: The existing technology's method of only cooling the cutting fluid through the coolant pipe cannot achieve better cooling efficiency, easily leading to situations such as heat accumulation and deterioration of the cutting fluid. At the same time, when the turning tool is performing cutting operations, it cannot perform targeted cooling by spraying coolant at a fixed point on the turning tool and the material itself, thus reducing the cooling effect of the cutting fluid. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a turret lathe for intelligent machining of pipe valve parts. The technical problem to be solved is that the cutting fluid storage unit can make cold air continuously circulate, thereby reducing the temperature of the cutting fluid in the cutting fluid pipe, enabling the cutting fluid to maintain a relatively stable cooling effect, and avoiding the drawback of cooling effect attenuation caused by long-term cooling work. Further improving the cooling effect of the cutting fluid on the turning tool, through the cooperation of the intelligent control system and the spraying mechanism, the temperature of the turning tool can be continuously monitored. When the temperature of the turning tool is too high, the position of the spray head is automatically adjusted through the control panel to spray the cutting fluid, thus achieving the effect of automatically spraying the cutting fluid at a fixed point to cool the turning tool. At the same time, because of the high accuracy of spraying the cutting fluid, the cooling effect of the cutting fluid is further improved. The air-cooling temperature reduction device can blow cold air to the turning tool or the material during machining, achieving a local range of temperature reduction effect. By cooperating with the sprinkler head to spray the cutting fluid on the turning tool or the material, the purpose of cooling and temperature reduction in combination with the range and the local area can be achieved, further improving the cooling and temperature reduction effect on the turning tool or the material.

[0019] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Refer to Figures 1 to 2 , a turret lathe for intelligent processing of pipe valve parts, including a machine tool 1, a spindle chuck 2, a sliding base 3, a turret 4, a processing box 5 and an intelligent control system 9. The intelligent control system 9 includes a control panel 91 and a temperature monitoring device 92. The spindle chuck 2 is connected to the machine tool 1. Through the spindle chuck 2, the material can be clamped on it, so as to facilitate the subsequent cutting operation of the material. It should be noted here that the specific chuck structure and the corresponding driving method on the spindle chuck 2 are both prior arts, and this solution will not be elaborated too much. The machine tool 1 is provided with an adjustment slide rail, and the sliding base 3 is slidably arranged on the adjustment slide rail. By moving the sliding base 3 on the adjustment slide rail, the turret 4 on the sliding base 3 can be driven to move horizontally. The turret 4 is slidably arranged on the sliding base 3. Multiple turning tools are installed on the turret 4. By adjusting the turning tool to move to the position of the material clamped by the spindle chuck 2, the cutting effect of the material can be achieved. A transverse adjustment slide rail is arranged on the sliding base 3, which can drive the turret 4 to move longitudinally to adjust the position of the turning tool on the turret 4 to facilitate the subsequent cutting operation.

[0021] It should be noted that the processing box 5 is arranged on the side of the turret 4 away from the spindle chuck 2. The inside of the processing box 5 is hollow. The inside of the processing box 5 is provided with a cutting fluid storage unit 51, which can store and cool the cutting fluid. By continuously conveying external air into the cutting fluid storage unit 51, the air circulation state can be maintained inside all the time, so that the cutting fluid can always be in a lower temperature range. When the cutting fluid is in a lower temperature range for a long time, the cutting fluid is not easy to deteriorate, and it will not be easy to deteriorate and stink because the cutting fluid is in a high temperature state for a long time, resulting in fluctuations in the pH value and affecting the cutting effect, so that the cooling and rust prevention effects of the coolant are significantly reduced. In this way, when the cutting fluid is sprayed onto the turning tool, a better cooling effect can be achieved for the turning tool or the material that generates high temperature during processing. A conveying pipe 6 is connected above the processing box 5. A positioning spraying mechanism 7 is arranged on the side of the conveying pipe 6 close to the spindle chuck 2. An air cooling device 8 is arranged above the positioning spraying mechanism 7.

[0022] Refer to Figures 1 to 8, the control panel 91 is provided on the conveying pipe 6. It can be connected to other positions on the machine tool 1 that do not affect the cutting operation, as long as the control panel 91 can be electrically connected to other components for normal use. A temperature monitoring device 92 is connected to the turret 4. The temperature monitoring device 92 is set on the turret 4 near the position of the turning tool on the turret 4, so as to measure the temperature of the turning tool during cutting to the greatest extent without affecting the cutting operation of the turning tool. The temperature monitoring device 92 is electrically connected to the control panel 91. The temperature of the turning tool is continuously monitored through the temperature monitoring device 92. When the temperature is higher than the set value, the data is sent to the control panel 91.

[0023] Among them, the cutting fluid storage unit 51 includes a U-shaped pipe rack 511, a first cutting fluid pipe 512, and at least two cooling fans 513. The U-shaped pipe rack 511 is connected to the side close to the spindle chuck 2, which can achieve the effect of air circulation in the U-shaped pipe rack 511, and then can reduce the temperature of the cutting fluid in the cutting fluid pipe, so that the cutting fluid can maintain a relatively stable cooling effect and avoid the drawback of cooling effect attenuation caused by long-term cooling work, further improving the cooling effect of the cutting fluid on the turning tool. The first cutting fluid pipe 512 is arranged inside the U-shaped pipe rack 511. One end of the first cutting fluid pipe 512 extends out of one side of the processing box 5 and is connected to the cutting fluid filtration and treatment bin 11 of the machine tool 1. The sprayed cutting fluid can be recycled and filtered through the cutting fluid filtration and treatment bin 11, and then pumped through the first cutting fluid pipe 512 to be sprayed out by the spray head 71 for the recycling use of the cutting fluid. The other end of the first cutting fluid pipe 512 extends out of the top of the processing box 5. Both cooling fans 513 are connected to one side of the U-shaped pipe rack 511. The rotation directions of the two cooling fans 513 are the same. By installing the two cooling fans 513 on both sides of the processing box 5, an air duct can be formed between the two cooling fans 513 to ensure the air circulation inside the processing box 5. Grooves are provided on both side walls of the processing box 5, and dust-proof nets are connected in the grooves. When external air enters the processing box 5, the external air can be filtered through the dust-proof nets, thereby reducing the dust accumulation degree inside the processing box 5.

[0024] Reference Figure 1 , 3 , Figure 4 and Figure 5Another embodiment: A refrigeration box 52 is connected to the side of the tool magazine 5 away from the turret 4. A refrigerator is installed inside the refrigeration box 52. The refrigerator operates based on the vapor compression cycle principle. The refrigerator includes a compressor, a condenser, an expansion valve, and an evaporator. The compressor compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gas and sends it to the condenser for heat dissipation and liquefaction. The liquid refrigerant becomes a low-temperature and low-pressure gas-liquid mixture after throttling and pressure reduction by the expansion valve and vaporizes by absorbing the surrounding heat in the evaporator, thereby achieving the refrigeration effect. Finally, the refrigerant returns to the compressor to complete the cycle. One end of the refrigerator is connected to a cold air pipe 53. One end of the cold air pipe 53 extends into the tool magazine 5. The cold air pipe 53 in the tool magazine 5 is placed in the air duct formed between two cold fans 513, so that when the two fans are started, the cold air will be blown, and the effect of cooling the cutting fluid pipe can be achieved. The other end of the cold air pipe 53 passes through the tool magazine 5 and extends into the refrigeration box 52 to be connected to the refrigerator. If only the external air is pumped into the tool magazine 5 to form air circulation inside to take away the heat dissipated by the cutting fluid in the cutting fluid pipe to achieve the cooling effect, this method can achieve a good effect in winter when the temperature is relatively low. Because the outdoor air temperature is low, a good cooling and heat dissipation can be achieved by pumping the external cold air into the tool magazine 5 to form a heat exchange. However, if in summer, the outdoor air temperature is very high, if this method is still used, a good cooling effect will not be achieved. At this time, a cold air pipe 53 can be added at the air duct formed between the two fans. In this way, the cold air blown by the cold fans 513 after operation can achieve the heat exchange effect, and thus the cutting fluid in the cutting fluid pipe can be cooled.

[0025] It is worth mentioning that different methods can be selected according to the usage environment. When it is winter or the room temperature is lower than 25 degrees, the cooling effect can be achieved only by pumping the external air into the tool magazine 5 through the cold fans 513. When it is summer or the room temperature is higher than 25 degrees, a cold air pipe 53 is added at the air duct formed between the two cold fans 513, and the cold air blown by the cold fans 513 can be used to cool the cutting fluid in the cutting fluid pipe. By selecting the corresponding usage method according to the different temperatures of the usage environment, a good usage effect can be achieved and energy can be saved at the same time.

[0026] Reference Figure 3 and Figure 4, multiple rectangular through-holes 5111 are provided on the U-shaped pipe support 511. One side of the U-shaped pipe support 511 close to the two cold fans 513 forms a non-closed contour with at least one open side 514. The open side 514 allows external media to freely enter and exit the internal space of the pipe body in the radial direction. By starting the two cold fans 513, external air can be driven into the pipe body. Since the open side 514 is provided on the side of the U-shaped pipe support 511 close to the two cold fans 513, external air can enter the U-shaped pipe support 511 and take away the heat emitted by the cutting fluid pipe, thereby reducing the temperature of the cutting fluid in the cutting fluid pipe. The open side 514 structure forms a directional channel for guiding the fluid. The open side 514 continuously extends along the axial direction of the pipe body by more than 80% of its total length. When the length of the open side 514 is larger, more heat emitted by the cutting fluid pipe in the U-shaped pipe support 511 can be taken away, resulting in a better cooling effect on the cutting fluid.

[0027] Reference Figures 1 to 7 , the spraying mechanism includes a spray head 71, a longitudinal moving frame 72, and a transverse adjusting frame 73. The spray head 71 is arranged between the two longitudinal moving frames 72. A longitudinal adjusting mechanism 721 is arranged inside the two longitudinal moving frames 72. The longitudinal adjusting mechanism 721 is connected to the spray head 71. Since the spray head 71 is connected to the longitudinal adjusting mechanism 721, as the longitudinal adjusting mechanism 721 drives the spray head 71 to move up and down, the height of the spray head 71 can be adjusted. The two transverse adjusting frames 73 are respectively arranged on both sides of the two longitudinal moving frames 72. A transverse adjusting mechanism 731 is arranged inside the two transverse adjusting frames 73. The transverse adjusting mechanism 731 is connected to the longitudinal moving frame 72. By the transverse adjusting mechanism 731, the longitudinal moving frame 72 can be adjusted to move horizontally, and thus the movement of the spray head 71 connected to the longitudinal moving frame 72 can be adjusted. The spray head 71 can be adjusted to move to the tool to spray cutting fluid for cooling according to the usage requirements, or when the tool cuts the material, the spray head 71 can be moved to the front of the tool at the material to be processed and the cutting fluid can be sprayed on the material itself to cool it, so that the material will not affect the processing quality due to excessive temperature during the cutting process.

[0028] It should be noted that the tops of the two longitudinal moving frames 72 are connected with a limiting plate 723. A limiting hole 724 is formed in the limiting plate 723. The inner wall of the limiting hole 724 is polished smoothly, and the edges of the limiting hole 724 at the top and bottom of the limiting hole 724 are smooth transition edges, so as to prevent the sharp edge of the limiting hole 724 from damaging the third cutting fluid pipe 711. A third cutting fluid pipe 711 is connected to the injection head 71. The other end of the third cutting fluid pipe 711 passes through the limiting hole 724 and extends into the conveying pipe 6. When the injection head 71 is located on the side of the transverse adjusting frame 73 close to the spindle chuck 2, the third cutting fluid pipe 711 is at its maximum limit. At this time, the third cutting fluid is in a straightened state. By passing the third cutting fluid pipe 711 through the limiting hole 724 of the limiting plate 723, the effect of limiting the third cutting fluid pipe 711 can be achieved, so that when the injection head 71 moves, a part of the third cutting fluid pipe 711 will not sag because it is not pulled tightly, and the third cutting fluid pipe 711 will contact the turret 4 or the turning tool, which will affect the cutting work. Through the setting of the limiting hole 724 on the limiting plate 723, the effect of limiting the third cutting fluid pipe 711 can be achieved, so that the third cutting fluid pipe 711 is limited above the injection head 71 and there will be no drawback of falling. A second cutting fluid pipe 62 is arranged inside the conveying pipe 6. One end of the second cutting fluid pipe 62 is connected to the third cutting fluid pipe 711, and the other end of the second cutting fluid pipe 62 extends out of the conveying pipe 6 and is connected to the first cutting fluid pipe 512. One end of the first cutting fluid pipe 512 located inside the conveying pipe 6 is connected to a water pump. By starting the water pump, the cutting fluid in the cutting fluid filtration and treatment bin 11 can be pumped into the first cutting fluid pipe 512, and then through the second cutting fluid and the third cutting fluid, and finally sprayed out through the injection head 71, so as to achieve the purpose of spraying cutting fluid. In this solution, the water pump is a micro water pump, and the specific power and model are set according to actual needs, and this solution is not limited.

[0029] Reference Figures 1 to 7 , the longitudinal adjusting mechanism 721 includes a slide rail and a slider. The slide rail is electrically connected to the control panel 91. Through the control panel 91, the power supply to the slide rail can be controlled to be energized or stopped. The slide rail is connected inside the longitudinal moving frame 72. The slider is slidably arranged on the slide rail. By energizing the slide rail, the magnetic field generated after energization interacts with the slider to generate Lorentz force or magnetic resistance, and the slider can be pushed to move. The slider is connected to the injection head 71 through a connecting rod. After the control panel 91 energizes the slide rail, the slider moves on the energized slide rail, thereby driving the injection head 71 connected through the connecting rod to move, and the effect of adjusting the height of the injection head 71 can be achieved. When it is necessary to spray cutting fluid on the turning tool for cooling operation, the injection head 71 can be adjusted to descend beside the turning tool, and then the turning tool can be sprayed with cutting fluid to achieve the purpose of cooling and cooling the turning tool.

[0030] Reference Figure 6 and Figure 7 The lateral adjustment mechanism 731 includes a first electric push rod and a push rod head slider. The first electric push rod is electrically connected to the control panel 91. The first electric push rod can be started or turned off through the control panel 91. The first electric push rod is connected inside the lateral adjustment frame 73. The push rod head slider is connected to the push head of the first electric push rod. By connecting a power supply to the first electric push rod, the push head of the first electric push rod can be moved, thereby driving the push rod head connected to its head to move. The push rod head slider is connected to the longitudinal moving frame 72 through a connecting rod. When the control panel 91 starts the first electric push rod, the push head of the first electric push rod moves horizontally at this time, so that the longitudinal moving frame 72 can be driven to move through the connecting rod, achieving the effect of adjusting the horizontal movement of the spray head 71. Thus, the spraying position of the spray head 71 can be adjusted according to the position of the turning tool or the processed material, and then the cutting fluid can be sprayed on the turning tool or the processed material to achieve the effect of cooling the material or the turning tool, avoiding the influence of the high temperature generated during long-term cutting work on the cutting work.

[0031] Reference Figures 1 to 7 Inside the conveying pipe 6, there is a second electric push rod. The second electric push rod is electrically connected to the control panel 91. The second electric push rod can be controlled to start or turn off through the control panel 91. The push head of the second electric push rod is connected with a moving block. One end of each of the two lateral adjustment frames 73 is connected to the moving block through a connecting block. By starting the second electric push rod through the control panel 91, the push head can drive the moving block to move longitudinally, and the movement of the moving block can adjust the movement of the two lateral adjustment frames 73, achieving the effect of adjusting the lifting of the spray head.

[0032] It is worth mentioning that since the control panel 91 is electrically connected to the temperature monitoring device 92, the slide rail, the first electric push rod and the second electric push rod, when the turning tool cuts the material clamped on the spindle chuck 2 for a long time, the temperature of the turning tool will gradually rise. The temperature monitoring device 92 located on the turret 4 continuously monitors the temperature of the turning tool below it. When the temperature of the turning tool is higher than the set value, at this time, the temperature monitoring device 92 sends the data higher than the set value to the control panel 91, and then adjusts the position of the spray head 71 through the control panel 91, so as to spray the cutting fluid on the turning tool at a fixed point, achieving the effect of spraying the cutting fluid at a fixed point to cool the turning tool; Further, when the control panel 91 receives data sent by the temperature monitoring device 92 that is higher than the set value, it first activates the first electric push rods located within the two lateral adjustment frames 73. At this time, the spray head can be adjusted to move horizontally, moving the spray head forward by a certain distance so that it is roughly above the cutting tool. Then, the second electric push rods located within the delivery pipe 6 are activated, and the two lateral adjustment frames 73 can be quickly adjusted to an appropriate height from the cutting tool or the material. After that, according to the subsequent requirements of spraying and cooling, the height of the spray head can be precisely adjusted in small amounts. At this time, through the control of the control panel 91, the slide rail within the longitudinal movement frame 72 is energized, which can drive the spray head 71 to move downward or upward, thereby precisely adjusting the height of the spray head 71, achieving the requirement of fixed-point spraying of cutting fluid, improving the accuracy of spraying cutting fluid, further enhancing the cooling effect of the cutting fluid. Through various adjustment methods of the spray head, it can meet the requirements of cooling operations by spraying cutting fluid on the cutting tool or the material during work. At the same time, through the continuous monitoring of the cutting tool temperature by the temperature monitoring device 92 and automatically adjusting the spray head 71 to perform fixed-point spraying of coolant on the cutting tool, it is not necessary to manually adjust the position of the spray head 71 during cutting operations, thus affecting the progress of the work.

[0033] Reference Figure 3 and Figure 8 , the air-cooling device 8 includes an air duct 81 and an air outlet 82. One end of the air duct 81 is connected to the delivery pipe 6, and the connection between the air duct 81 and the delivery pipe 6 is in a communicating state. The included angle between the air duct 81 and the delivery pipe 6 is less than or equal to 90°. The air outlet 82 is connected to the tail of the air duct 81 for air to flow out from the air outlet 82. The air outlet 82 is located above the cutting tool of the turret 4. When the cold air flows out from the air outlet 82 through the air duct 81, the cold air is exactly discharged towards the cutting tool, so that cold air can be blown to the cutting tool or the material during processing, achieving a local cooling effect. Cooperating with the spray head to spray cutting fluid on the cutting tool or the material can achieve the purpose of combined cooling of the range and the local area, further improving the cooling effect on the cutting tool or the material.

[0034] It should be noted that a blower fan 63 is provided inside the delivery pipe 6, and the blower fan 63 is close to the air duct 81. When the blower fan 63 is activated, the cold air located inside the processing box 5 can be transported through the delivery pipe 6 to the air duct 81, so that the cold air can be discharged through the exhaust fan. The delivery pipe 6 is connected to the processing box 5, and a through limiting hole 724 is provided at the connection between the delivery pipe 6 and the processing box 5, so that the delivery pipe 6 and the processing box 5 remain in a communicating state, allowing cold air to enter the delivery pipe 6 to achieve the effect of discharging cold air.

[0035] As used in the specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component.
