Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of milling equipment, and specifically relates to a machine body processing milling equipment with a chip cleaning function. BACKGROUND

[0002] Milling refers to using a rotating multi-blade cutter to cut a workpiece, and is a high-efficiency processing method. During work, the cutter rotates (as a main motion), the workpiece moves (as a feed motion), and the workpiece can also be fixed, but the rotating cutter must also move (simultaneously completing the main motion and the feed motion) at this time. The machine tool for milling is a horizontal milling machine or a vertical milling machine, or a large gantry milling machine. These machine tools can be ordinary machine tools or numerical control machine tools. Milling is a cutting process using a rotating milling cutter as a tool, and is generally performed on a milling machine or a boring machine. Milling is suitable for processing planes, grooves, various shaped surfaces (such as milling keys, gears, and threads), and special surfaces of molds.

[0003] The milling equipment cuts the workpiece by rotating the milling cutter. During processing, a large amount of waste chips is generated. The waste chips increase the temperature of the milling cutter during processing, which causes the cutter to wear.

[0037] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example: Figures 1-8 As shown, the present invention provides a technical solution for a machine body milling equipment with a chip cleaning function. The milling equipment includes a table assembly 1, a tool assembly 2, a drive unit 3, a chip cutting assembly 4, and a cleaning assembly 5. The drive unit 3 is located at the top of the table assembly 1, and the tool assembly 2 is located between the drive unit 3 and the table assembly 1. The chip cutting assembly 4 is located inside the tool assembly 2. The chip cutting assembly 4 is used to clean the waste chips wrapped around the tool. The cleaning assembly 5 is located at the bottom of the table assembly 1 and is used to collect waste materials and separate the waste materials.

[0039] Specifically, milling equipment uses a rotating milling cutter to cut the workpiece, generating a large amount of waste chips during processing. These chips increase the temperature of the milling cutter itself, leading to tool wear. Furthermore, the chips become entangled on the milling cutter, increasing the rotational pressure and affecting its speed. Long, thin chips are also difficult to collect, easily tangling and clogging the drain hole, causing waste liquid accumulation. Table assembly 1 holds the workpiece, cutter assembly 2 performs the cutting, drive unit 3 provides power to operate cutter assembly 2, chip removal assembly 4 cleans the chips entangled on the milling cutter and breaks long, thin chips into shorter pieces, and cleaning assembly 5 collects and separates the waste, separating the chips from the waste liquid to improve recycling efficiency.

[0040] like Figures 2-4As shown, the tool assembly 2 comprises a tool seat 21, a tool handle 22 and a tool body 23. The tool seat 21 is located at the output end of the driving unit 3. The tool handle 22 is located in the tool seat 21. One end of the tool handle 22 is matched with the tool seat 21. The other end of the tool handle 22 is provided with the tool body 23. The tool body 23 is fixedly connected with the tool handle 22. A through groove is formed in the middle of the tool handle 22. A through hole 231 is formed in one end of the tool body 23. The through hole 231 is located at the side of the tool body 23 away from the tool handle 22. A helical groove 232 is formed in the outer wall of the tool body 23.

[0041] Specifically, the tool seat 21 is located at the output end of the driving unit 3. The tool handle 22 and the tool body 23 on the tool seat 21 are controlled to rotate by the driving unit 3. The central axis of the tool handle 22 and the tool body 23 is provided with a through groove. The two through grooves are communicated with each other. The through groove is used for placing the hydraulic pipeline 41. The through hole 231 in one end of the tool body 23 is used for discharging the cooling liquid in the hydraulic pipeline 41. The through hole 231 is located at the end of the tool body 23 away from the tool handle 22. Therefore, when cutting is performed, the through hole 231 is close to the workpiece. After the cooling liquid passes through the tool body 23, the temperature of the tool can be controlled. The cooling liquid enters the polishing hole. Therefore, under the flow of the cooling liquid, the waste scraps are moved out of the polishing hole, reducing the winding of the waste scraps on the tool body 23.

[0042] As shown in the figure, Figures 2-4 The chip removal assembly 4 comprises a hydraulic pipeline 41 and a resistance wire 43. A plurality of sawteeth 233 are formed on the helical groove 232. The sawteeth 233 are arranged at equal intervals. The hydraulic pipeline 41 is located in the through groove. The hydraulic pipeline 41 and the through groove are on the same central axis. One end of the hydraulic pipeline 41 is fixedly connected with the tool seat 21. The other end of the hydraulic pipeline 41 is provided with a sliding pipeline 42. One end of the sliding pipeline 42 is slidably connected with the hydraulic pipeline 41. The other end of the sliding pipeline 42 is communicated with the through hole 231. The detection assembly 6 is arranged between the sliding pipeline 42 and the hydraulic pipeline 41. The resistance wire 43 is wound on the outer surface of the sliding pipeline 42.

[0043] Specifically, the chip-cutting assembly 4, through the temperature control of the coolant and in conjunction with the saw teeth 233, widens the gap between the saw teeth 233 as the coolant temperature increases, thereby cutting the chips wrapped around the cutter body 23 and preventing chips from remaining wrapped around the cutter body 23 during milling. The hydraulic pipe 41, with one end close to the tool holder 21, is connected to an external pipe for coolant flow. The hydraulic pipe 41 is fixedly connected to a through groove. The sliding pipe 42 is located at the end of the hydraulic pipe 41 furthest from the tool holder 21, and one end of the sliding pipe 42 is slidably connected to the hydraulic pipe 41. It is used to detect the pressure at one end of the cutter body 23, thereby determining whether chips are accumulating. A detection component exists between the sliding pipe 42 and the hydraulic pipe 41. 6 is used to detect the moving distance of the sliding pipe 42, and then the resistance wire 43 is used to heat the coolant in the sliding pipe 42 to achieve temperature control of the liquid in the pipe. The saw tooth 233 is a nickel-titanium alloy chip breaker groove. At normal temperature, the narrow groove width of the chip breaker groove is 0.5mm, which is suitable for conventional cutting. When the cutting temperature exceeds 200℃, the nickel-titanium alloy deforms and the groove width expands to 1.2mm, forcing the chip to curl and break. After the temperature drops, it automatically resets. The coolant is a synthetic ester coolant. The synthetic ester coolant is an existing technology. It is usually made by esterification reaction of C2-C4 polyol and C4-C15 carboxylic acid. It has high temperature resistance and can work at a temperature of 200℃-300℃.

[0044] like Figure 3 , Figure 4 As shown, the detection component 6 includes a compression column 61, a slide cylinder 62, and a strain gauge 63. A circular block 64 is provided on the outer wall of the sliding pipe 42. A slide cylinder 62 is provided at one end of the circular block 64 close to the hydraulic pipe 41. The bottom end of the slide cylinder 62 is fixedly connected to the circular block 64. A compression column 61 is provided at the top end of the slide cylinder 62. The compression column 61 and the slide cylinder 62 are slidably connected. A spring 65 is provided between the compression column 61 and the slide cylinder 62. The strain gauge 63 is located in the cylinder groove. The slide cylinder 62 and the compression column 61 are on the same central axis.

[0045] Specifically, the detection assembly 6 is used to measure the moving distance of the sliding pipe 42. When cutting, the waste is gathered on the outer wall and the bottom end of the tool. When the waste is wound on the tool or not quickly discharged, the waste is pressed in the polishing hole, which affects the cutting process. When the waste is gathered in the polishing hole, the end of the tool body 23 close to the workpiece is pressed by the waste, and the end of the sliding pipe 42 in the tool body 23 is pressed by the waste, moving towards the end of the tool shank 22. When the sliding pipe 42 moves, it drives the circular block 64 to move, and the movement of the circular block 64 drives the sliding cylinder 62 to move, and the sliding cylinder 62 drives the spring 65 to push the pressing column 61 to move, and the movement of the pressing column 61 presses the strain gauge 63. The strain gauge 63 is deformed under pressure, which causes the resistance value of the strain gauge 63 to decrease. According to the change of the resistance value, the moving distance of the sliding pipe 42 is inferred, and then it is judged whether the waste is accumulated or not, and the pressure and temperature of the cooling liquid are controlled. When the cooling liquid is heated, the nickel-titanium alloy chip breaking groove expands, improving the cutting efficiency of the long strip-shaped waste, and changing the long strip-shaped waste into broken shape, preventing the long strip-shaped waste from winding on the milling cutter or accumulating in the processing groove. Based on the punching force of the cooling liquid and the centrifugal force generated by the high-speed rotation of the milling cutter, the broken waste is moved out of the processing groove, realizing that the waste cannot accumulate at the bottom end of the milling cutter, and then the sliding pipe lacks the extrusion of the accumulated waste. The sliding pipe moves out of the through hole due to its own weight, the strain gauge lacks the extrusion of the pressing column, the resistance value is lower than the set value, the heating element stops working, and finally realizes that when the accumulation occurs in the processing groove, the sliding pipe is pressed, the heating element starts to work, the nickel-titanium alloy chip breaking groove of the milling cutter expands under the heat, and the nickel-titanium alloy chip breaking groove in the processing groove is cut. At the same time, under the driving of the cooling liquid and the milling cutter, the waste quickly moves out of the processing groove, the accumulation amount of the waste in the processing groove is reduced, the strain gauge lacks extrusion, and the heating element stops working immediately. The overall process of the heating element is short in working time.

[0046] As shown in Figure 4 , the end of the sliding pipe 42 close to the through hole 231 is provided with a fixed block 66, and the fixed block 66 is provided with a temperature sensing element 67.

[0047] Specifically, the temperature sensing element 67 detects the working temperature of the tool itself when the resistance wire 43 is not working, and detects the temperature of the cooling liquid in the pipe when the resistance wire 43 is working.

[0048] As shown in Figure 1 , Figure 6As shown, the table assembly 1 comprises a support column 11, a flat plate 12 and a workbench 13, the support column 11 stands on the horizontal ground, the top end of the support column 11 is provided with the flat plate 12, the support column 11 and the flat plate 12 are fixedly connected, the upper surface of the flat plate 12 is provided with a groove 121, the workbench 13 is located in the groove 121, the workbench 13 and the bottom end of the groove 121 are fixedly connected, the two sides of the groove 121 are provided with liquid holes 122, and the bottom end of the flat plate 12 is provided with a cleaning assembly 5.

[0049] Specifically, the table assembly 1 is used for placing workpieces, the support column 11 is used for fixing the flat plate 12, so that the flat plate 12 stands on the horizontal ground, the groove 121 on the flat plate 12 is used for placing the workbench 13 and collecting waste liquid, preventing waste liquid from overflowing, and the waste generated during work will flow to the groove 121 on the workbench 13, then gather in the groove 121 and flow to the liquid hole 122, and then flow to the cleaning assembly 5 from the liquid hole 122, and the cleaning assembly 5 is used for collecting and separating waste liquid, improving the recycling efficiency.

[0050] As shown in Figure 7 , Figure 8 , the cleaning assembly 5 comprises a bottom block 51 and a collection bin 52, the bottom block 51 is located at the bottom end of the flat plate 12, the top end of the bottom block 51 is fixedly connected with the flat plate 12, the upper surface of the bottom block 51 is provided with a collection groove 511, the inside of the bottom block 51 is provided with a flow channel 512, the flow channel 512 is in communication with the collection groove 511, the collection bin 52 is located at the bottom end of the bottom block 51, the internal space of the collection bin 52 is in communication with the flow channel 512, and the inner wall of the collection bin 52 is provided with a bubble unit 54 at the bottom end.

[0051] Specifically, the waste liquid flows to the top end of the bottom block 51 through the liquid hole 122, is caught by the collection groove 511 in the bottom block 51, and finally gathers at the flow channel 512, so that the waste liquid flows to the collection bin 52 through the flow channel 512, so that the waste liquid generated during work is all gathered in the collection bin 52, and the waste liquid will be deposited in the collection bin 52, wherein the cooling liquid will be accumulated at the bottom end of the collection bin 52, and the waste will float on the top end of the cooling liquid, so that the two are separated, and then the bubble unit 54 at the bottom end of the collection bin 52 is used to provide bubbles in the waste liquid, the generated bubbles will adhere to the waste, so that the waste floats, thereby accelerating the separation of the waste and the cooling liquid.

[0052] As shown in Figure 8 , the bottom block 51 is provided with a metal ring 55, the metal ring 55 is sleeved on the flow channel 512, the top end of the collection bin 52 is provided with a scraper 56, one end of the collection bin 52 is provided with a pushing motor 57, the fixed end of the pushing motor 57 is fixedly connected with the outer wall of the collection bin 52, and the output end of the pushing motor 57 is fixedly connected with the scraper 56.

[0053] Specifically, the metal ring 55 is located at the outlet end of the flow channel 512, and the metal ring 55 is connected with an external power source to generate an electric field, so that the waste liquid and the waste chips in the waste liquid pass through the metal ring 55, which causes the capacitance value to change. The more waste chips, the larger the capacitance value, and vice versa. Then, the content of the waste chips in the waste liquid is determined according to the capacitance value, and whether the waste chips are normally discharged is determined. The strain gauge 63 and the metal ring 55 control the working condition of the resistance wire 43, and the motor 57 is used as a power source to control the movement of the scraper 56, so as to clean the waste chips at the top of the liquid surface.

[0054] Working principle: When the milling cutter works, the cooling liquid enters the cutter through the hydraulic pipeline 41, which affects the cutter. After the cooling liquid passes through the cutter body 23, the cooling liquid also enters the polishing hole, so that under the flow of the cooling liquid, the waste chips move out of the polishing hole, reducing the winding of the waste chips on the cutter body 23. The waste chips will continue to be produced and will gather on the outer wall and the bottom end of the cutter. When the waste chips are wound on the cutter or not quickly discharged, the waste chips will be extruded in the polishing hole, which will affect the cutting process. When the waste chips gather in the polishing hole, the end of the cutter body 23 close to the workpiece will be extruded by the waste chips, and one end of the sliding pipeline 42 in the cutter body 23 will be extruded by the waste chips and move towards one end of the cutter handle 22. When the sliding pipeline 42 moves, the circular block 64 moves, and the movement of the circular block 64 drives the sliding cylinder 62 to move. The sliding cylinder 62 drives the spring 65 to push the extrusion column 61 to move, and the movement of the extrusion column 61 extrudes the strain gauge 63. The strain gauge 63 is deformed under pressure, which causes the resistance value of the strain gauge 63 to decrease, the control resistance wire 43 heats up, and the temperature of the cooling liquid increases. When the temperature exceeds 200℃, the nickel-titanium alloy deforms to expand the groove width to 1.2mm, forcing the chips to curl and break. When the sliding pipeline 42 returns to the original position, the resistance wire 43 stops heating. The waste produced during work will flow to the groove 121 on the workbench 13, then gather in the groove 121 and flow to the through liquid hole 122. The waste liquid flows to the top end of the bottom block 51 through the through liquid hole 122, is caught by the collection groove 511 in the bottom block 51, and finally gathers at the waste liquid flow channel 512. The cooling liquid will accumulate at the bottom end of the collection bin 52, and the waste chips will float on the top end of the cooling liquid, realizing the separation of the two. Then, the air bubble unit 54 at the bottom end of the collection bin 52 is used to provide air bubbles in the waste liquid, and the generated air bubbles will adhere to the waste chips, making the waste chips float, thereby accelerating the separation of the waste chips and the cooling liquid. When the waste liquid passes through the metal ring 55, the waste chips in the waste liquid also pass through the metal ring 55, which causes the capacitance value to change. The more waste chips, the larger the capacitance value, and vice versa. Then, the content of the waste chips in the waste liquid is determined according to the capacitance value, and whether the waste chips are normally discharged is determined. The strain gauge 63 and the metal ring 55 control the working condition of the resistance wire 43, and the motor 57 is used as a power source to control the movement of the scraper 56, so as to clean the waste chips at the top of the liquid surface.
