Description

Technical Field

[0001] This invention relates to the field of parts processing technology, and more specifically, to a turning apparatus for processing mechanical parts. Background Technology

[0002] In the turning process, cutting fluid is usually used to cool the cutting tool and the workpiece. Cutting fluid usually contains a variety of components, and its main purpose is to improve the efficiency and quality of cutting through lubrication, cooling and cleaning. Machine tool cutting fluid mist is a common phenomenon in metal cutting process, which can be mainly attributed to two mechanisms: atomization and evaporation.

[0003] Currently, in the turning process, to prevent oil and gas from spreading and polluting the environment, cutting fluid mist treatment equipment is required. Chinese Patent Publication No. CN120347546A proposes a vertical CNC machine tool based on an intelligent control system and its high-precision machining method. The vertical CNC machine tool includes a worktable, a tool post, and a rotary table. A protective plate is installed around the rotary table. A rotating mechanism rotates synchronously within the worktable at the bottom of the rotary table. A fluid collection box and a material collection box are fixedly installed within the worktable at the bottom of the rotary table, and the fluid collection box and the material collection box are assembled into a circular box. The material feeder guides the debris on the filter screen to the collection box for storage, thus separating the cutting fluid from the debris. The baffle isolates the oil and gas evaporating in the collection box from the external environment. The baffle then moves up to draw the evaporated oil and gas in the collection box into the return pipe. The oil and gas are liquefied into cutting fluid through the cooling delivery pipe. This not only achieves the recycling of cutting fluid, but also utilizes the cooling capacity of the liquefied cutting fluid itself to cool the cutting fluid in the narrow opening, thereby reducing the evaporation of the cutting fluid in the narrow opening.

[0004] Therefore, the existing technology described above limits the contact between the debris and the cutting fluid by isolating the debris in the chamber. However, since the debris in the chamber is in a state of continuous accumulation, when new debris falls into the chamber, the original debris that has not been completely cooled will come into contact with the residual cutting fluid that has fallen off the new debris, thereby increasing the amount of cutting fluid volatilization and affecting recycling. Summary of the Invention

[0005] The present invention provides a turning apparatus for machining mechanical parts, which separates the primary scrap from the secondary scrap by using a reversing arc, thereby solving the problem mentioned in the background art, namely: the original, not fully cooled chips come into contact with the residual cutting fluid that has fallen off the new chips.

[0006] To achieve the above objectives, a turning device for machining mechanical parts includes a machining table, a frame, a turning head, a base, and a rotating device for driving the base to rotate. A dividing cone located outside the rotating device is fixedly installed on the machining table. Guide boxes are symmetrically fixed at both ends of the dividing cone. The guide boxes are fixed to the machining table, and a material feeding mechanism is provided on the dividing cone to periodically move the waste material on the dividing cone into the guide boxes.

[0007] The bottom of the dividing cone is equipped with a material pouring mechanism, which includes a liquid collection part and a material pouring arc that is rotatably set in the guide box. In the initial stage, the dividing cone is responsible for isolating the waste material on one side, while the cutting fluid is guided to the liquid collection part for temporary storage.

[0008] The material-pouring arc is used to control the liquid in the material guide box. When the liquid collection section is in the liquid storage stage, the liquid collection section drives the material-pouring arc to rotate counterclockwise, forcing the first waste on the material-pouring arc to pour out of the material guide box. When the liquid level in the liquid collection section reaches a preset amount, the material-pouring arc moves the secondary waste to the material guide box through the material-push mechanism and separates it from the first waste. At the same time, it blocks the evaporation of cutting fluid in the material guide box.

[0009] The dividing cone is an inverted funnel shape with a first filter screen on the outer inclined surface and a cylindrical bottom. Symmetrical partitions are fixedly installed at the connection between the inclined surface and the cylinder. The partitions are used to restrict waste from falling from the first filter screen. There is a gap between the two partitions, which corresponds to the feed inlet of the guide box.

[0010] The liquid collection section includes a liquid collection box fitted at the top of the dividing cone and at the bottom of the dividing cone. A tension spring is elastically connected between the liquid collection box and the dividing cone. A liquid infusion tube is connected to the bottom of the liquid collection box. The bottom of the liquid infusion tube is fitted inside the liquid inlet tube. An electric valve is provided on the liquid inlet tube. A liquid storage tank is connected to the bottom of the liquid inlet tube.

[0011] The pouring arc is a quarter-circle arc, with a second filter screen on one right-angled side and the arc length, and a baffle on the other right-angled side. The baffle is in contact with the inner wall of the guide box under normal conditions.

[0012] An oil-absorbing cotton is provided inside the second filter screen of the arc length. The oil-absorbing cotton is responsible for intercepting small particles dripping into the cutting fluid. A liquid guide tube is connected between the bottom of the guide box and the liquid storage tank.

[0013] A discharge port is provided on one side of the material guide box, and a material discharge box is fixedly installed on one side of the discharge port. Symmetrical through holes are provided at the bottom of the material discharge box, and a material guide plate is fixedly installed inside the material discharge box to guide the dumped waste material to the through holes on both sides.

[0014] Uprights are fixedly installed on both sides of the liquid collection box. A push plate is installed at the bottom of the uprights. One end of the push plate is sloping and the other end goes into the guide box and contacts the baffle. A bracket fixed to the guide box is slidably connected to the bottom of the liquid collection box.

[0015] A guide plate is fixedly installed on the inner wall of the guide box. One end of the guide plate is inclined downward to guide the waste in the guide box to the second filter screen with right angle side. Under normal conditions, a discharge channel for waste to pass through is formed between the guide plate and the inner wall of the guide box.

[0016] When the second filter screen on the right-angle side rotates to fit against the feed plate, an isolation zone for accommodating secondary waste is formed between the second filter screen on the arc-length side and the inner wall of the feed box. The feed plate and the second filter screen on the arc-length side restrict the contact between the secondary waste and the primary waste, and the oil-absorbing cotton and the feed plate restrict the evaporation of cutting fluid from the bottom wall of the feed box.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] In this turning device for machining mechanical parts, when the cutting fluid in the collection box reaches the preset discharge amount, the pouring arc rotates counterclockwise until it contacts the feed plate. The pouring arc pours out the first waste material, and at the same time, the pouring arc and the feed plate match to isolate the secondary waste material in the isolation zone, limiting the evaporation of the cutting fluid and separating the first waste material from the secondary waste material. This prevents the residual liquid on the secondary waste material from contacting the first waste material, which would cause the cutting fluid to evaporate and affect recycling.

[0036] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0037] Therefore, in view of the above-mentioned problems, the present invention discloses a turning apparatus for machining mechanical parts, with reference to... Figure 1-3As shown, the system includes a machining table 100, a frame 101, a turning head 102, a base 103, and a rotating device for rotating the base 103. A dividing cone 110 located outside the rotating device is fixedly mounted on the machining table 100. Guide boxes 120 are symmetrically fixed at both ends of the dividing cone 110. The guide boxes 120 are fixed to the machining table 100, and a material feeding mechanism is provided on the dividing cone 110 to periodically move the waste material on the dividing cone 110 into the guide boxes 120. First, based on Figure 3 Based on and combined Figure 4 , Figure 5 As shown, it should be understood that the rotating device is a turntable 104 fixed to the base 103. A liquid distribution plate 106 is provided at the bottom of the turntable 104. A base plate 107 is fixedly connected to the bottom of the liquid distribution plate 106, and the radius of the liquid distribution plate 106 is larger than the top radius of the dividing cone 110. A first motor 105 for driving the turntable 104 to rotate is fixed at the bottom of the liquid distribution plate 106. In this way, when the first motor 105 is started, the first motor 105 drives the turntable 104 to rotate, and the cutting fluid carrying the waste generated on the parts falls onto the dividing cone 110 through the liquid distribution plate 106.

[0038] Secondly, to prevent waste material and cutting fluid from being thrown outward under centrifugal force during the rotation of turntable 104, a protective cover (not shown in the figure) can be installed on the distributor plate 106. A gap is left between the bottom of the protective cover and the distributor plate 106 so that the cutting fluid can carry the waste material through the gap. This will not be described in detail here.

[0039] Next, a material discharge mechanism 200 is provided at the bottom of the dividing cone 110. The material discharge mechanism 200 includes a liquid collection section and a material discharge arc 210 rotatably disposed within the guide box 120. In the initial stage, the dividing cone 110 is responsible for isolating the waste material on one side, while the cutting fluid is guided to the liquid collection section for temporary storage. The material discharge arc 210 is used to control the liquid in the waste material within the guide box 120 (the waste material within the guide box 120 is in a static state, and the remaining liquid drips off the waste material under gravity). When the liquid collection section is in the... During the liquid accumulation stage, the liquid collection section drives the pouring arc 210 to rotate counterclockwise, forcing the initial waste material on the pouring arc 210 to pour out of the guide box 120. When the liquid level in the collection section reaches a preset amount, the pouring arc 210 pushes the secondary waste material in the guide box 120 to separate it from the initial waste material. At the same time, it blocks the evaporation of cutting fluid in the guide box 120, thereby preventing the residual liquid on the secondary waste material from contacting the initial waste material, which would increase the evaporation of cutting fluid. The specific process is shown below:

[0040] First, the dividing cone 110 is inverted funnel-shaped, with a first filter screen on its outer inclined surface and a cylindrical bottom. Symmetrically fixed partitions 115 are located at the connection between the inclined surface and the cylinder. The partitions 115 restrict waste material from falling from the first filter screen. A notch is present between the two partitions 115, corresponding to the feed inlet of the guide box 120. On the other hand, as... Figure 5 , Figure 6 As shown, the material feeding mechanism includes a scraper 111 attached to the inclined surface. The end of the scraper 111 rests on the dividing cone 110. A toothed ring 112 located on the inner top wall of the dividing cone 110 is fixedly connected to the end of the scraper 111. The toothed ring 112 meshes with a gear 114. The gear 114 is connected to a second motor 113 fixed on the base plate 107. Thus, when the part is being cut, the waste material generated falls onto the first filter screen, while the cutting fluid flows through the first filter screen to the bottom. At this time, the scraper 111 is driven to rotate by the toothed ring 112. The scraper 111 rotates on the first filter screen and pushes the waste material to the notch. The waste material falls into the guide box 120 through the notch and the feed inlet, thereby achieving the initial separation of the cutting fluid and the waste material.

[0041] Return to Figure 2 , Figure 3 As shown, since the pouring arc 210 is rotatably connected to the guide box 120, the waste material falling into the guide box 120 is supported by the pouring arc 210. At this time, the waste material on the pouring arc 210 enters a static liquid control state, while the cutting fluid passing through the dividing cone 110 is collected in the liquid collection section. The specific structure of the liquid collection section is shown below. The liquid collection section includes a liquid collection box 220 with its top sleeved on the bottom of the dividing cone 110. A tension spring 116 is elastically connected between the liquid collection box 220 and the dividing cone 110. A liquid delivery pipe 223 is connected to the bottom of the liquid collection box 220. The bottom of the liquid delivery pipe 223 is sleeved in the liquid inlet pipe 132. The liquid inlet pipe 132 has an electric valve, and the bottom of the liquid inlet pipe 132 is connected to a liquid storage tank 130. Therefore, referring to... Figure 4 As shown, in the initial state of the liquid collection box 220, the distance between the bottom of the liquid collection box 220 and the top of the liquid inlet pipe 132 is L1. When the liquid collection box 220 is in the liquid storage stage, the cutting fluid drips into the liquid collection box 220. At this time, the electric valve is closed, and the cutting fluid is stored in the liquid collection box 220. The liquid level in the liquid collection box 220 gradually rises, the weight increases, the tension spring 116 is stretched, and the elastic potential energy increases.

[0042] When the liquid level in the collection box 220 reaches the preset discharge level (detected by a liquid level sensor installed in the collection box 220), that is, when the distance the collection box 220 drops is the difference between L1 and L2, the electric valve opens, and the cutting fluid in the collection box 220 is discharged into the storage tank 130 through the delivery pipe 223 and the inlet pipe 132. Then, after the cutting fluid in the collection box 220 has been discharged, the collection box 220 is pulled upward and reset under the elastic action of the tension spring 116, and then the liquid is stored again. The above is the entire liquid storage process.

[0043] It should be noted that, Figure 7 , Figure 8 The connection state between the dividing cone 110 and the collection box 220 is shown. When the collection box 220 drops by the difference between L1 and L2, the top of the collection box 220 is still misaligned with the bottom of the dividing cone 110.

[0044] Combination Figure 9 , Figure 10 The diagram illustrates the specific structure of the pouring arc 210. The pouring arc 210 is a quarter-circle arc. A second filter 211 is provided on one right-angled side and along the arc length. The other right-angled side is a baffle 213. Under normal conditions, the baffle 213 is in contact with the inner wall of the guide box 120. Thus, waste falling into the guide box 120 will first remain on the second filter 211 on the right-angled side, causing residual liquid on the waste to fall off under gravity. Furthermore, within the second filter 211 along the arc length… Oil-absorbing cotton 212 is provided on the side, which is responsible for intercepting small particles in the dripping cutting fluid. A liquid guide pipe 131 is connected between the bottom of the feed box 120 and the liquid storage tank 130. Thus, the waste material is intercepted on one side by the second filter screen 211, and the residual liquid is separated from the waste material. The oil-absorbing cotton 212 reduces the particle content in the cutting fluid flowing back from the feed box 120 to the liquid storage tank 130, thereby reducing the cutting fluid filtration pressure on the liquid storage tank 130 in the later stage, so as to facilitate recycling.

[0045] In addition, to discharge the waste material after settling, a discharge port 122 is provided on one side of the guide box 120, and a discharge box 214 is fixedly installed on one side of the discharge port 122. Symmetrical through holes 215 are provided at the bottom of the discharge box 214, and a guide plate 216 is fixedly installed inside the discharge box 214 to guide the dumped waste material to the through holes 215 on both sides; when the discharge arc 210... Figure 9 Rotate counterclockwise to Figure 10 In the state, the waste on the second filter screen 211 rolls down into the discharge box 214 under the action of gravity, and is dispersed by the guide plate 216 to be discharged from the through hole 215, thereby completing the discharge of waste.

[0046] Furthermore, the power for the counterclockwise rotation of the pouring arc 210 comes from the fact that uprights 221 are fixedly installed on both sides of the liquid collection box 220, and push plates 222 are installed at the bottom of the uprights 221. One end of the push plate 222 is sloping, and the other end passes into the guide box 120 and contacts the baffle 213. The bottom of the push plate 222 is slidably connected to the bracket 123 fixed to the guide box 120. Thus, when the liquid collection box 220 is in the process of accumulating liquid, the liquid collection box 220 drives the uprights 221 to move downward. The uprights 221 apply downward pressure to the slope. According to the force decomposition, under the action of the uprights 221, the push plate 222 will be driven to push the baffle 213 to one side, so that the pouring arc 210 rotates against the gravity of the waste on the second filter screen 211. As the moving distance of the push plate 222 increases, the rotation angle of the pouring arc 210 increases until the waste is completely discharged.

[0047] Next, a guide plate 121 is fixedly installed on the inner wall of the guide box 120. One end of the guide plate 121 is inclined downward to guide the waste material in the guide box 120 to the right-angled side second filter screen 211. Under normal conditions, a discharge channel 124 for waste material to pass through is formed between the guide plate 121 and the inner wall of the guide box 120. In addition, when the right-angled side second filter screen 211 rotates to fit against the guide plate 121, an isolation zone 125 for accommodating secondary waste material is formed between the arc-length side second filter screen 211 and the inner wall of the guide box 120. The guide plate 121 and the arc-length side second filter screen 211 restrict the contact between the secondary waste material and the primary waste material, and the oil-absorbing cotton 212 and the guide plate 121 restrict the evaporation of cutting fluid from the bottom wall of the guide box 120. Working principle:

[0048] When the scrap falls into the guide box 120, it is guided by the feed plate 121 and the discharge channel 124 to the second filter screen 211 on the right-angle side. In this state, the scrap accumulates on one side of the second filter screen 211 on the right-angle side. When the push plate 222 pushes the baffle 213 to rotate counterclockwise, the scrap on the second filter screen 211 on the right-angle side rolls from one side to the other. During this process, residual liquid falls off the surface of the rolling scrap, reducing residual liquid residue on the scrap. When the second filter screen 211 contacts the feed plate 121, secondary scrap enters from the feed port of the guide box 120. The secondary scrap is intercepted at the isolation zone 125, separating the secondary scrap from the primary scrap, and preventing residual liquid on the secondary scrap from contacting the primary scrap, which would increase the amount of cutting fluid evaporation.

[0049] In summary, when the cutting fluid in the collection box 220 reaches the preset discharge amount, the pouring arc 210 rotates counterclockwise to contact the feed plate 121. The pouring arc 210 pours out the first waste material, and at the same time, the pouring arc 210 and the feed plate 121 match to isolate the secondary waste material in the isolation zone 125, which restricts the evaporation of the cutting fluid and separates the first waste material from the secondary waste material. This prevents the residual liquid on the secondary waste material from contacting the first waste material, which would cause the cutting fluid to evaporate and affect recycling.

[0050] Finally, after the first waste is discharged, the cutting fluid in the collection box 220 is also discharged. The collection box 220 moves upward, and the pouring arc 210 rotates clockwise to reset. First, the reset process of the pouring arc 210 is as follows: During the cutting process, the size of the generated chips is small. Therefore, in a short time, the secondary waste falls to the isolation zone 125, and the space occupied by the accumulated waste is relatively small. This makes the friction between the waste and the arc surface of the pouring arc 210 in the isolation zone 125 smaller.

[0051] Furthermore, the overall mass of the pouring arc 210 is much greater than that of the waste accumulated in the isolation zone 125. The angle of rotation of the pouring arc 210 rotates from the starting position to the contact position with the feed plate 121. At this time, the overall weight of the pouring arc 210 is biased to the right, while the connection between the pouring arc 210 and the feed box 120 is biased to the left. Therefore, under the action of gravity, the pouring arc 210 overcomes the friction with the debris in the isolation zone 125 and rotates clockwise.

[0052] Secondly, the frictional resistance at the rotating connection between the pouring arc 210 and the guide box 120 is negligible; and for the pouring arc 210 to rotate clockwise, the clockwise rotation torque generated by the gravity of the pouring arc 210 itself is much greater than the frictional torque between the secondary waste and the pouring arc 210; that is, the torque generated by gravity is much greater than the resistance torque encountered during its rotation, thus enabling the pouring arc 210 to rotate clockwise.

[0053] Then, liquid is stored again, at which point the secondary waste falls onto the second filter screen 211.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
