Description

Technical Field

[0001] The present invention relates to the technical field of numerical control machine tools, and more specifically, to a vertical numerical control machine tool based on an intelligent control system and its high-precision machining method. Background Art

[0002] Cutting fluid usually contains various components, and its main purpose is to improve the efficiency and quality of cutting machining through functions such as lubrication, cooling, and cleaning. Mist of machine tool cutting fluid is a common phenomenon in the metal cutting process, which can mainly be attributed to two mechanisms: atomization and evaporation.

[0003] Currently, in order to prevent oil and gas from diffusing into the external environment and polluting it, equipment for treating cutting fluid mist is required. In Chinese Patent Publication No.: CN117942676A, a machine tool cutting fluid mist separation and filtration device is proposed, which includes a filter cylinder, a shunt cylinder, a telescopic pipe, an anti-drawing-empty type oil filtering mechanism, and an emptying type extraction mechanism. The shunt cylinder is communicatively arranged on both sides of the telescopic pipe, the filter cylinder is communicatively arranged on the side of the shunt cylinder away from the telescopic pipe, the anti-drawing-empty type oil filtering mechanism is arranged inside the filter cylinder, and the emptying type extraction mechanism is arranged on the telescopic pipe. By communicatively arranging the oil and gas treatment structure with the machine tool cabinet door, the oil and gas generated during the operation of the machine tool are fully absorbed, thereby reducing the diffusion of oil and gas.

[0004] Since the chips generated during the turning process can be separated from the cutting fluid through the filter plate, however, when the feed rate of the tool rest during turning instantaneously increases, the amount of generated chips increases, resulting in more oil and gas evaporated when the cutting fluid contacts the chips. At this time, the suction machine cannot limit too much oil and gas from diffusing outward, thereby affecting the surrounding working environment. Summary of the Invention

[0005] The present invention provides a vertical numerical control machine tool based on an intelligent control system, which uses a material pushing rod to guide the chips on the filter screen into the aggregate box for storage, separating the cutting fluid from the chips. The partition plate cuts off the evaporated oil and gas in the aggregate box from the external environment, and then uses the upward movement of the isolation plate to suck the evaporated oil and gas in the aggregate box into the return pipe. The oil and gas are liquefied into cutting fluid through the cold quantity delivery pipe, thus solving the problems raised in the above background art, that is: To achieve the above object, the vertical numerically controlled machine tool based on an intelligent control system includes a workbench, a vertical tool rest, and a rotating table. A guard plate is arranged around the rotating table. A rotating mechanism rotates synchronously inside the workbench at the bottom of the rotating table. A liquid collecting box and a debris collecting box are fixedly arranged inside the workbench at the bottom of the rotating table. The liquid collecting box and the debris collecting box are spliced into a circular ring box body. The upper part of the liquid collecting box is open and provided with a filter screen. The rotating mechanism rotates to dial the debris on the filter screen into the debris collecting box, separating the debris from the cutting fluid. An isolation mechanism is elastically arranged inside the liquid collecting box. A collecting mechanism is arranged between the liquid collecting box and the debris collecting box to cool the oil and gas in the debris collecting box and liquefy the oil and gas into a liquid. The isolation mechanism moves downward to isolate the cutting fluid collected inside the liquid collecting box from the external environment, restricting the outward diffusion of the oil and gas inside the isolation mechanism. When moving upward, it guides distilled water into the liquid collecting box for storage for recycling use.

[0006] A vertical cylinder is fixedly arranged at the top of the rotating shaft. The vertical cylinder is slidably arranged with the material dialing rod. A compression spring is elastically connected between the inside of the vertical cylinder and the material dialing rod. On the other hand, the filter screen forms a notch at the position of the debris collecting box. An arc-shaped plate that fits both ends of the filter screen is arranged at the notch. A partition plate is movably arranged in the middle of the arc-shaped plate to block the cutting fluid evaporated inside the debris collecting box from the external environment. The top of the partition plate is in an inclined shape. An auxiliary plate whose two ends fit the inner wall of the debris collecting box is fixedly arranged at the bottom of the partition plate. A return spring is elastically arranged between the auxiliary plate and the debris collecting box. Specifically during operation, as the material dialing rod rotates, the material dialing rod dials the debris on the filter screen onto the arc-shaped plate. During this process, since the elastic potential energy of the return spring is less than the elastic potential energy of the compression spring, when the material dialing rod rotates from the arc-shaped plate to the partition plate, the material dialing rod downwardly overcomes the elastic potential energy of the return spring to push the partition plate downward. When the partition plate is blocked by the return spring below, the partition plate stops moving downward, and the inside of the debris collecting box is connected to the external environment. At this time, the material dialing rod still continues to rotate and dials the debris to fall from the inclined surface of the partition plate into the debris collecting box, thus achieving the purpose of separating the debris from the cutting fluid.

[0007] The second object of the present invention is to provide a high-precision machining method for a vertical numerically controlled machine tool based on an intelligent control system, including the following method steps: S1. When machining a workpiece, first place the workpiece on the rotating table and fix it. Input corresponding parameters on the control system to control the movement of the vertical tool rest, the feed rate of the tool tip, and the rotation speed of the rotating table. S2. The motor drives the rotating shaft to rotate. The filter screen separates the cutting fluid from the debris. The material dialing rod rotates synchronously with the rotating shaft and dials the debris on the filter screen into the debris collecting box for storage. The partition plate blocks the cutting fluid evaporated inside the debris collecting box from the external environment to restrict the escape of oil and gas. S3. When the isolation plate moves up, the evaporated oil and gas in the collecting box are sucked, so that the oil and gas are liquefied into liquid and flow back into the collecting box, thereby reducing the temperature of the cutting fluid in the collecting box and realizing the recycling of the cutting fluid.

[0008] Compared with the prior art, the present invention has the following beneficial effects: 1. Use the material pusher to guide the debris on the filter screen to the collection box for storage, so that the cutting fluid is separated from the debris. The partition separates the evaporated oil and gas in the collection box from the external environment. Then use the partition plate to move 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 cold delivery pipe. This not only realizes the recycling of the cutting fluid, but also can use the coldness of the liquefied cutting fluid itself to cool the cutting fluid in the narrow mouth, thereby reducing the evaporation of cutting in the narrow mouth.

[0009] 2. When the cutting fluid flows from the wide mouth into the narrow mouth, the oil-absorbing cotton can effectively filter out the tiny metal impurities in the cutting fluid. With its porous structure and large specific surface area, the impurities can be trapped in the pores, thereby purifying the cutting fluid for recycling and reducing production costs. In addition, the cutting fluid at the narrow mouth evaporates to form oil and gas, and the oil-absorbing cotton absorbs the evaporated oil and gas molecules, reducing the diffusion of oil and gas and improving the working environment.

[0010] 3. The isolation plate moves down from the wide mouth to the narrow mouth, forcing the pressure in the narrow mouth to increase and discharge the cutting fluid in the narrow mouth. In addition, the isolation plate can also limit the evaporation of the cutting fluid in the narrow mouth. At the same time, the isolation plate presses the air to pass through the oil-absorbing cotton, thereby discharging the oil and gas adsorbed in the oil-absorbing cotton, reducing the saturation of the oil-absorbing cotton, and causing the cutting fluid dripping from the top to enter the narrow mouth when moving upward.

Detailed implementation mode

[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0014] Since the chips generated during the turning process can be separated from the cutting fluid through the filter plate. However, when the feed rate of the tool rest increases instantaneously during turning, the amount of chips generated increases, resulting in more oil and gas evaporated when the cutting fluid contacts the chips. At this time, the suction machine cannot limit the excessive outward diffusion of oil and gas, thus affecting the surrounding working environment. The present invention provides a vertical numerical control machine tool based on an intelligent control system. See Figures 1-3 As shown in the figure, it includes a workbench 100, a vertical tool rest 101 and a rotary table 102. The vertical tool rest 101 and the rotary table 102 are operated by a control system (not shown in the figure). A guard plate 103 is arranged around the rotary table 102. When machining a workpiece, first place the workpiece on the rotary table 102 and fix it, and input parameters on the control system to realize the machining of the workpiece; A rotating mechanism 110 rotates synchronously inside the workbench 100 at the bottom of the rotary table 102. A liquid collecting box 120 and an aggregate box 130 are fixedly arranged inside the workbench 100 at the bottom of the rotary table 102. The liquid collecting box 120 and the aggregate box 130 are spliced into a circular ring box body. The upper part of the liquid collecting box 120 is open and provided with a filter screen 121. The rotating mechanism 110 turns to dial the chips on the filter screen 121 into the aggregate box 130 to separate the chips from the cutting fluid; Among them, during the rotation of the turntable 102, the chips generated during the turning of the workpiece fall onto the filter screen 121, and the cooled cutting fluid flows through the filter screen 121 into the liquid collection box 120 for storage. Since the temperature of the chips falling onto the filter screen 121 is relatively high, if not processed in time, they will accumulate. When new cutting fluid drips, the temperature of the cutting fluid flowing through the chips increases, which easily causes the evaporation of the cutting fluid. Therefore, the specific structure of the rotating mechanism 110 is shown below. The rotating mechanism 110 includes a motor 111, a rotating shaft, and a material shifting rod 112. A bracket 111a is fixedly arranged between the motor 111 and the workbench 100. The rotating shaft is coaxially connected to the output shaft of the motor 111. A plurality of material shifting rods 112 that are in contact with the filter screen 121 are arranged at the top of the rotating shaft. By starting the motor 111, the motor 111 drives the rotating shaft to rotate, and the rotating shaft and the material shifting rods 112 rotate synchronously. The material shifting rods 112 shift the chips that fall onto the filter screen 121 into the aggregate box 130 (the process is shown below), thereby separating the chips from the cutting fluid and preventing the cutting fluid from contacting the chips.

[0015] The principle of the filter screen 121 shifting the chips into the aggregate box 130 is as follows: First, as shown in Figure 4 and Figure 5 , a vertical cylinder 114 is fixedly arranged at the top of the rotating shaft. The vertical cylinder 114 is slidably arranged with the material shifting rod 112. A compression spring 115 is elastically connected between the inside of the vertical cylinder 114 and the material shifting rod 112. On the other hand, the filter screen 121 forms a notch at the position of the aggregate box 130. An arc-shaped plate 131 that is in contact with both ends of the filter screen 121 is arranged at the notch. A partition plate 132 for blocking the evaporated cutting fluid in the aggregate box 130 from the external environment is movably arranged in the middle of the arc-shaped plate 131. The top of the partition plate 132 is inclined. An auxiliary plate 133 whose two ends are in contact with the inner wall of the aggregate box 130 is fixedly arranged at the bottom of the partition plate 132. A return spring 134 is elastically arranged between the auxiliary plate 133 and the aggregate box 130 (refer to Figure 6 and Figure 7 for illustration); Specifically during operation, as the material shifting rod 112 rotates, the material shifting rod 112 shifts the chips on the filter screen 121 onto the arc-shaped plate 131. During this process, since the elastic potential energy of the return spring 134 is less than the elastic potential energy of the compression spring 115, when the material shifting rod 112 rotates from the arc-shaped plate 131 to the partition plate 132, the material shifting rod 112 downwardly overcomes the elastic potential energy of the return spring 134 and pushes the partition plate 132 downward. When the partition plate 132 is blocked by the return spring 134 below, the partition plate 132 stops moving downward, and the inside of the aggregate box 130 is communicated with the external environment. At this time, the material shifting rod 112 still continues to rotate and shifts the chips to fall from the inclined surface of the partition plate 132 into the aggregate box 130, thereby achieving the purpose of separating the chips from the cutting fluid; Next, since the bottom of the partition plate 132 was blocked when sliding along the inclined surface of the partition plate 132 previously, the feeding rod 112 was lifted upward to compress the compression spring 115, and the elastic potential energy of the compression spring 115 increased. Therefore, when the feeding rod 112 disengaged from the top end of the inclined surface of the partition plate 132, the compression spring 115 instantaneously pushed the feeding rod 112 to strike the arc-shaped plate 131 under its elastic action, while the arc-shaped plates 131 at other positions struck the filter screen 121, causing the cutting fluid to drip into the liquid collection box 120, thereby reducing the residue and evaporation of the cutting fluid on the filter screen 121.

[0016] Secondly, considering that the temperature of the cutting fluid increases after contacting the chips collected in the aggregate box 130 and evaporation also occurs during storage in the aggregate box 130, for this reason, the upper end of the aggregate box 130 is set as a wide opening, and the bottom end is set as a narrow opening. An oil-absorbing cotton 122 that can absorb oil and gas and intercept impurities in the cutting fluid is arranged in the narrow opening. In this way, when the cutting fluid flows from the wide opening into the narrow opening, the oil-absorbing cotton 122 can effectively filter out fine metal impurities in the cutting fluid. With its porous structure and large specific surface area, the impurities are intercepted in the pores, realizing the purification of the cutting fluid for recycling and reducing production costs. Moreover, the cutting fluid evaporates to form oil and gas at the narrow opening, and the oil-absorbing cotton 122 adsorbs the evaporated oil and gas molecules, reducing the diffusion of oil and gas and improving the working environment.

[0017] Furthermore, in order to recycle the evaporated oil and gas in the aggregate box 130, an isolation mechanism 150 is elastically arranged inside the liquid collection box 120, and a collection mechanism 140 that cools the oil and gas in the aggregate box 130 to liquefy the oil and gas is arranged between the liquid collection box 120 and the aggregate box 130. The isolation mechanism 150 moves downward to isolate the cutting fluid collected inside the liquid collection box 120 from the external environment, so as to limit the outward diffusion of the oil and gas in the isolation mechanism 150. When moving upward, distilled water is guided into the liquid collection box 120 for storage for recycling use.

[0018] Thus, returning to Figure 2 、 Figure 4 、 Figure 6 As shown in Also, since a drain pipe 124 is connected to the bottom of the liquid collection box 120 (refer to Figure 2As shown, an intake pipe 123 is externally connected, and first one-way valves are provided in both the drain pipe 124 and the intake pipe 123. Therefore, when the partition plate 151 moves upward, the first one-way valve in the drain pipe 124 is used to allow external air to enter the liquid collection box 120, and when the partition plate 151 moves upward, the first one-way valve in the intake pipe 123 is used to allow the cutting fluid to be discharged from the liquid collection box 120, so as to realize the recycling of the cutting fluid; On the other hand, the principle of realizing the reciprocating up and down movement of the partition plate 151 is as follows. A vertical rod 153 is fixedly arranged at the bottom of the partition plate 151, and a movable ring 152 is fixedly arranged at the bottom of the vertical rod 153. Wave plates 154 which are misaligned with the material pushing rods 112 are arranged on the movable ring 152 in an array manner. A cross bar 113 is slidably arranged on the wave plates 154, and the cross bar 113 is fixedly arranged with the rotating shaft; Among them, Process 1: When the material pushing rod 112 slides from the filter screen 121 to the partition plate 132, under the action of the wave plate 154, the cross bar 113 slides along the track of the wave plate 154 and presses on the wave plate 154, so that the wave plate 154 pulls the vertical rod 153 downward, that is, the partition plate 151 moves downward from the wide opening to the narrow opening, forcing the pressure in the narrow opening to increase, discharging the cutting fluid in the narrow opening, and at the same time, the partition plate 151 can also limit the evaporation of the cutting fluid in the narrow opening. At the same time, the partition plate 151 presses the air to pass through the oil absorption cotton 122, thereby discharging the oil and gas adsorbed in the oil absorption cotton 122 and reducing the saturation of the oil absorption cotton 122; Process 2 (that is, Figure 6 the state shown by the cross bar 113 and the wave plate 154 in): When the material pushing rod 112 slides onto the partition plate 132, the partition plate 132 opens, and the cross bar 113 slides downward from the top of the wave plate 154, that is, under the elastic action of the tension spring 150a, the partition plate 151 moves from the narrow opening to the wide opening. The partition plate 151 will draw in external air from the intake pipe 123, and at the same time suck the evaporated oil and gas in the aggregate box 130. The sucked oil and gas are cooled through the collection mechanism 140; Next, on the basis of Figure 3 and Figure 6 and in combination with Figure 7 as shown, the collection mechanism 140 includes a gas collection box 141 communicated with the aggregate box 130, and a reflux pipe 142 with one end communicated with the narrow opening of the liquid collection box 120. The reflux pipe 142 is communicated with the gas collection box 141. The end of the reflux pipe 142 connected to the gas collection box 141 tilts upward, and the other end sinks to form an inclined end. A cold quantity delivery pipe 143 penetrates through the inclined end. The cold quantity delivery pipe 143 is communicated with an external cold quantity supply device. By delivering cold quantity into the cold quantity delivery pipe 143, the oil and gas in the reflux pipe 142 will be liquefied into bead-shaped cutting fluid when encountering cold, and the cutting fluid flows through the reflux pipe 142 and flows into the liquid collection box 120 for storage; That is to say, when the debris on the partition plate 132 drops into the aggregate box 130, the isolation plate 151 moves upward to draw in the evaporated oil and gas from the return pipe 142, which can prevent the evaporated oil and gas in the aggregate box 130 from escaping outward when the partition plate 132 is opened, thereby reducing the pollution to the surrounding environment.

[0019] Working principle: When the debris on the surface of the partition plate 132 slides into the aggregate box 130, the isolation plate 151 moves upward and draws in air from the intake pipe 123 in the reverse direction. Since the diameter of the return pipe 142 is larger than that of the intake pipe 123, in order to meet the normal upward movement of the isolation plate 151, the amount of air drawn into a single intake pipe 123 is limited, so it takes some time for the isolation plate 151 to move upward and reset. Therefore, additional air needs to be drawn from the return pipe 142, that is, a negative pressure is formed in the return pipe 142, so that the evaporated oil and gas in the aggregate box 130 is liquefied after passing through the cold quantity delivery pipe 143. The formed cutting fluid flows back into the narrow opening of the liquid collection box 120 through the return pipe 142; It should be noted that: the connection between the return pipe 142 and the liquid collection box 120 is horizontally lower than the oil absorption cotton 122 (refer to Figure 6 the dotted line marking), so that it can be directly mixed with the cutting fluid in the liquid collection box 120, saving time. Secondly, a second one-way valve is provided at the connection between the return pipe 142 and the liquid collection box 120. The second one-way valve is used to allow the liquefied cutting fluid to flow into the narrow opening. The purpose is to directly mix the cutting fluid formed by the liquefaction of the oil and gas with the cutting fluid in the liquid collection box 120, which can cool the cutting fluid in the liquid collection box 120 to reduce the evaporation of the cutting fluid; That is to say, the debris on the filter screen 121 is guided into the aggregate box 130 for storage by the material pushing rod 112, so that the cutting fluid is separated from the debris. The partition plate 132 cuts off the evaporated oil and gas in the aggregate box 130 from the external environment, and then the isolation plate 151 moves upward to draw the evaporated oil and gas in the aggregate box 130 into the return pipe 142. The oil and gas is liquefied into cutting fluid through the cold quantity delivery pipe 143. This not only realizes the recycling of the cutting fluid, but also can use the cold quantity of the already liquefied cutting fluid itself to cool the cutting fluid in the narrow opening, thereby reducing the evaporation of the cutting in the narrow opening.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.

The connection of the return pipe (142) with the liquid collection box (120) is lower than the oil absorption cotton (122) in the horizontal direction. A second one-way valve is arranged at the connection of the return pipe (142) with the liquid collection box (120), and the second one-way valve is used to allow the liquefied cutting fluid to flow into the narrow opening.

8. A high-precision machining method for operating the vertical numerically controlled machine tool based on an intelligent control system described in claim 4, characterized in that, It includes the following method steps: S1. When processing a workpiece, first place the workpiece on the rotating table (102) and fix it, and input corresponding parameters on the control system to control the movement of the vertical tool rest (101), the feed rate of the tool tip, and the rotation speed of the rotating table (102); S2. The motor (111) drives the rotating shaft to rotate. The filter screen (121) separates the cutting fluid from the debris. The material pushing rods (112) rotate synchronously with the rotating shaft and push the debris on the filter screen (121) into the aggregate box (130) for storage. The partition plate (132) blocks the cutting fluid evaporated in the aggregate box (130) from the external environment to limit the escape of oil and gas; S3. When the isolation plate (151) moves upward, the evaporated oil and gas in the aggregate box (130) are sucked, so that the oil and gas are liquefied into a liquid by the collection mechanism (140) and flow back into the aggregate box (130), reducing the temperature of the cutting fluid in the aggregate box (130) and realizing the recycling of the cutting fluid.
