Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of milling machines, in particular to a high-efficiency milling machine. BACKGROUND

[0002] The milling machine can process various surfaces of the workpiece through the milling cutter. Generally, the milling cutter is the main movement of the rotary movement, and the movement of the workpiece and the milling cutter is the feeding movement. It can process planes, grooves, and various curved surfaces, gears, etc.

[0003] When the milling cutter is in high-speed rotation and contacts the workpiece, the friction is large, thereby generating a large amount of heat. In order to cool the milling cutter and the workpiece, it is necessary to spray cooling liquid or cutting fluid during processing. At the same time, a large amount of debris will flow into the collecting device together with the cooling liquid during cutting. In order to reuse the cooling liquid, it is necessary to filter out the debris in the cooling liquid.

[0004] For example, the Chinese utility model patent with the application number CN202121930971.8 and the publication number CN218253080U, and the name "milling machine facilitating chip removal" includes a milling machine assembly, a filtering and cleaning assembly, a cleaning and recycling assembly, and a waste chip collecting assembly. During work, metal chips and cooling liquid leak from the bottom of the milling machine body, flow onto the first filter plate for preliminary filtering, and pass through the second filter plate for re-filtering. When a certain amount of cooling liquid is collected in the box, the cooling liquid in the box can be pumped into the liquid return pipe by starting the liquid pump. The liquid return pipe is in communication with the cooling liquid pipeline in the milling machine body, so as to realize the recycling of the cooling liquid. When there are many debris on the first filter plate, the cooling liquid discharged through the cleaning pipe is used to flush the first filter plate, and the debris is collected through the collecting box. By starting the motor to drive the threaded rod to rotate, the second filter plate is cleaned to the collecting box, so as to realize the collection of debris.

[0005] Although the above-mentioned patent provides a milling machine that can separate debris from cooling liquid and realize the recycling of the cooling liquid, it has the following disadvantages: during work, the debris remaining on the filter screen needs to be cleaned into the collecting box. In the prior art, when cleaning the debris on the filter screen, it is necessary to repeatedly spend time and observe the amount of debris remaining on the filter screen at irregular intervals. When the amount of debris reaches a certain amount, the driving mechanism is started to clean the debris on the filter screen to the collecting box.

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figures 1-8 As shown, an embodiment of the present invention provides a high-efficiency milling machine, including a recovery mechanism for recovering coolant. The recovery mechanism includes a collection box 6 with an open top. A movable plate 11 is suspended in the inner cavity of the collection box 6 by a connecting rope 8. The outer surface of the movable plate 11 is slidably sealed to the inner wall of the collection box 6 to divide the inner cavity of the collection box 6 into an upper receiving cavity 601 and a lower receiving cavity 602. A filter screen 3 is rotatably arranged in the upper receiving cavity 601. The filter screen 3 is connected to the connecting rope 8 by a transmission mechanism.

[0032] Coolant flows through filter screen 3 into upper receiving cavity 601. When the coolant in upper receiving cavity 601 reaches a certain amount, it squeezes the movable plate 11 to move down so that the transmission mechanism driven by the connecting rope 8 can drive the filter screen 3 to flip and remove debris from the filter screen 3.

[0033] The high-efficiency milling machine provided in this embodiment is used for turning and milling workpieces, and separates the coolant and generated debris during the machining process so that the coolant and debris can be recycled separately. In this embodiment, terms related to direction and position such as "up," "down," "left," and "right" are relative to the accompanying drawings. Specifically, the high-efficiency milling machine includes a support frame 13, on which a milling cutter 15 that moves along the Z-axis is slidably mounted, and a worktable 16 that can move along the X and Y axes is slidably mounted. The milling cutter 15 can rotate under the drive of a motor. The support frame 13 is also equipped with a spraying mechanism for spraying coolant. The coolant sprayed from the spraying mechanism is directed at the milling cutter 15 to cool it down. Under the action of the coolant, the metal debris generated during the operation of the milling cutter 15 mixes with the sprayed coolant. All of the above are prior art and will not be elaborated further. The support frame 13 has a waste liquid tank 18 at its bottom, where coolant and debris are collected. A pump body 17 is connected to the side of the waste liquid tank 18, and a guide pipe 19 is connected to the output end of the pump body 17. A hose 20 is sealed to the end of the guide pipe 19, and the end of the hose 20 is inserted into the collection tank 6 from the top and positioned above the filter screen 3. By driving the pump body 17, the coolant and debris collected in the waste liquid tank 18 flow together through the guide pipe 19 and the hose 20 into the collection tank 6. Alternatively, the coolant and debris in the waste liquid tank 18 can be introduced into the collection tank 6 without using the pump body 17. Specifically, a riser (not shown in the figure) is installed at the bottom of the support frame 13 so that the bottom height of the waste liquid tank 18 is higher than the top height of the collection tank 6. Under the action of potential energy, the coolant and debris in the waste liquid tank 18 can automatically flow into the collection tank 6. The collection box 6 is equipped with a filter screen 3. Under the action of the filter screen 3, the coolant passes through the filter screen 3, while the debris in the coolant remains on the filter screen 3.The function of the recovery mechanism is to recover coolant. The movable plate 11 is suspended inside the collection tank 6 by the connecting rope 8. The other end of the connecting rope 8 is connected to a transmission mechanism, which is mounted on the collection tank 6 and connected to the filter screen 3. The outer surface of the movable plate 11 slides and seals against the inner wall of the collection tank 6, allowing the movable plate 11 to slide up and down. The connecting rope 8, along with the filter screen 3 and the transmission mechanism, limits the movement of the movable plate 11, ensuring it is stably suspended at a specific height. When the movable plate 11 slides downwards, the connecting rope 8 drives the transmission mechanism, which in turn causes the filter screen 3 to flip outwards from the collection tank 6. The force driving the movable plate 11 downwards comes from the coolant entering the collection tank 6. Specifically, regardless of the height at which the movable plate 11 is located... The inner cavity of the collection box 6 is always divided into two by the movable plate 11. The upper cavity 601 is located above the movable plate 11, and the lower cavity 602 is located below the movable plate 11. The existence of the lower cavity 602 is to allow the movable plate 11 to slide down. The collection box 6 is equipped with an exhaust pipe 603 that is connected to the bottom of the lower cavity 602. The exhaust pipe 603 is used to allow gas to enter and exit so that the movable plate 11 can slide up and down. The collection box 6 is also equipped with a drain pipe 605 located above the exhaust pipe 603. When the movable plate 11 slides down to the bottom, its top surface is at the same height as the bottom of the inner cavity of the drain pipe 605, so that the coolant in the upper cavity 601 can be discharged from the drain pipe 605. A sealing cap (not shown in the figure) is threaded onto the drain pipe 605. When it is necessary to drain the coolant, the sealing cap can be opened.

[0034] The coolant entering the collection tank 6 from the top is filtered by the filter screen 3 and then blocked by the movable plate 11, accumulating in the upper receiving cavity 601. Debris remains on the filter screen 3. When the coolant in the upper receiving cavity 601 reaches a certain weight, the gravity of the coolant drives the movable plate 11 to move downwards. The downward movement of the movable plate 11 drives the transmission mechanism via the connecting rope 8. The transmission mechanism causes the filter screen 3 to flip outwards from the collection tank 6, thereby cleaning the debris on the filter screen 3 to a designated position. When the filter screen 3 flips outwards from the collection tank 6, the hose 20 is lifted by the filter screen 3 without interfering with the flow. The filter screen 3 is separated, so even after the filter screen 3 is flipped, the coolant discharged from the hose 20 will still be filtered through the filter screen 3 before flowing into the collection box 6. After cleaning, the coolant in the upper receiving cavity 601 is discharged, and the filter screen 3 is rotated into the collection box 6 to reset. The reset action of the filter screen 3 drives the transmission mechanism to drive the movable plate 11 to slide upward through the connecting rope 8 to reset, so as to facilitate the next cleaning of the debris on the filter screen 3. It can be seen that in the entire process of cleaning the debris on the filter screen 3, the operator does not need to spend time and effort repeatedly observing the amount of debris left on the filter screen 3. In the prior art, when cleaning the debris on the filter screen, it is necessary to repeatedly spend time and periodically observing the amount of debris left on the filter screen. When the debris reaches a certain amount, the drive mechanism is activated to clean the debris on the filter screen to the collection box. This undoubtedly increases the time consumption and work procedures of the operator, thus affecting the overall working efficiency of the milling machine.

[0035] In this embodiment, by suspending a movable plate 11 in the inner cavity of the collection box 6 via a connecting rope 8, the inner cavity of the collection box 6 is divided into an upper receiving cavity 601 and a lower receiving cavity 602. At this time, the movable plate 11 is located at the bottom plate of the upper receiving cavity 601, which is used to receive coolant. As the amount of coolant entering the upper receiving cavity 601 increases, it drives the movable plate 11 to slide downward. The downward movement of the movable plate 11 drives the transmission mechanism via the connecting rope 8 to rotate the filter screen 3. The rotation of the filter screen 3 can remove the debris remaining on the filter screen 3 to a specific position, thereby achieving debris cleaning. The entire process does not require the operator to spend time and effort to observe the amount of debris remaining on the filter screen. Compared with the prior art, the present invention only needs to utilize the increase of coolant entering the collection box 6 to achieve automatic cleaning of debris on the filter screen 3, without adding extra time consumption and workflow for the operator to observe the debris remaining on the filter screen, thereby improving the overall working efficiency of the milling machine.

[0036] In this embodiment, the transmission mechanism includes a receiving box 1 that is at a certain angle to and fixedly connected to the filter screen 3. The receiving box 1 is rotatably connected to the collection box 6. This rotatable connection between the receiving box 1 and the collection box 6 enables the rotatable connection between the filter screen 3 and the collection box 6. Therefore, the filter screen 3 and the receiving box 1 rotate synchronously. The filter screen 3 is fixedly installed below the open opening of the receiving box 1, and the top surface of the filter screen 3 is not lower than the bottom surface of the open opening of the receiving box 1. The open opening of the receiving box 1 faces the filter screen 3. During the flipping process of the filter screen 3, debris flows into the receiving box 1 along the filter screen 3. Specifically, when cleaning the debris remaining on the filter screen 3, the filter screen 3 is driven by the transmission mechanism to rotate towards the outside of the collection box 6 (e.g., ...). Figure 6 As shown in the figure, at this time, the filter screen 3 and the receiving box 1 rotate synchronously toward the outside of the collection box 6, so that the filter screen 3 is tilted downwards, and the debris slides into the receiving box 1 along the tilted filter screen 3, thereby collecting the debris.

[0037] In this embodiment, the transmission mechanism further includes a first toothed roller 4 and a second toothed roller 5 rotatably disposed outside the collection box 6. The first toothed roller 4 is fixedly connected to the receiving box 1 and meshes with the second toothed roller 5. One end of the connecting rope 8 is fixedly connected to the second toothed roller 5, and the other end of the connecting rope 8 slides through the collection box 6 and is fixedly connected to the center of the movable plate 11. An annular groove 501 is formed on the outer circumferential surface of the second toothed roller 5. The end of the connecting rope 8 is fixedly installed in the annular groove 501 and partially wound in the annular groove 501 so that the connecting rope 8 can be released, thereby allowing the movable plate 11 to slide down. Specifically, when the movable plate 11 is pressed down by the coolant in the upper receiving cavity 601 and slides down, the movable plate 11 generates a downward pulling force on the connecting rope 8. At this time, the connecting rope 8 pulls the second toothed roller 5 to rotate counterclockwise. The counterclockwise rotation of the second toothed roller 5 drives the first toothed roller 4 to rotate clockwise. The clockwise rotation of the first toothed roller 4 drives the receiving box 1 and the filter screen 3 to rotate clockwise, that is, to rotate towards the outside of the collection box 6, so that the debris on the filter screen 3 slides into the receiving box 1. Similarly, after the debris slides into the receiving box 1, the sealing cap on the drain pipe 605 is opened to drain the coolant in the upper receiving cavity 601 to the designated position. Then, a counterclockwise force is applied to the receiving box 1 or the filter screen 3, causing the receiving box 1 and the filter screen 3 to rotate counterclockwise, thereby driving the first toothed roller 4 to rotate counterclockwise. The counterclockwise rotation of the first toothed roller 4 drives the second toothed roller 5 to rotate counterclockwise, thereby releasing the connecting rope 8. At this time, under the gravity of the movable plate 11, the connecting rope 8 moves downward to tighten it. When the filter screen 3 rotates to its reset position, the movable plate 11 also resets. A baffle 604 is fixedly installed on the inner wall of the collecting box 6 to limit the movement of the filter screen 3. When the filter screen 3 is in its initial state, the bottom of the filter screen 3 abuts against the top of the baffle 604, thus limiting the movement of the filter screen 3, the receiving box 1, and the movable plate 11. The filter screen 3 is made of hard metal and has sufficient rigidity.

[0038] Furthermore, a first directional roller 7 is rotatably mounted on the outside of the collection box 6, and a second directional roller 10 is rotatably mounted in the upper receiving cavity 601. The connecting rope 8 located between the second toothed roller 5 and the movable plate 11 passes around the first directional roller 7 and the second directional roller 10 in sequence so that the connecting rope 8 is perpendicular to the movable plate 11. Thus, the connecting rope 8 can pull the movable plate 11 to slide upward stably and is less likely to get stuck.

[0039] The second toothed roller 5 is fixedly installed with a limiting plate 502 that abuts against the first toothed roller 4. During the rotation of the first toothed roller 4, it abuts against the limiting plate 502 to stop the container box 1 and the filter screen 3 from rotating. That is, when the receiving box 1 rotates towards the outside of the collection box 6, the first toothed roller 4 and the limiting plate 502 will continuously approach each other until the first toothed roller 4 collides with the limiting plate 502. At this time, the receiving box 1 and the filter screen 3 stop rotating, and the first toothed roller 4 collides with the limiting plate 502, which can cause the filter screen 3 to vibrate, making it easier for debris to slide into the receiving box 1. When less debris from the filter screen 3 enters the receiving box 1, a counterclockwise force is applied to the receiving box 1 or the filter screen 3 intermittently, so that the first toothed roller 4 and the limiting plate 502 can collide repeatedly, thereby allowing the debris from the filter screen 3 to slide into the receiving box 1. Of course, a vibration motor (not shown in the figure) can also be installed outside the collection box 6. Under the action of the vibration motor, the filter screen 3 can always generate vibration force, thereby allowing more debris to enter the receiving box 1.

[0040] Furthermore, a counterweight 104 is fixedly installed on the receiving box 1. In the initial state, the center of gravity of the counterweight 104 is located in the same vertical plane as the rotation center of the first toothed roller 4. When the filter screen 3 flips to separate the debris from the filter screen 3, the center of gravity of the counterweight 104 is biased towards the side of the rotation center of the first toothed roller 4 away from the filter screen 3, thereby increasing the collision force between the first toothed roller 4 and the limiting plate 502, so as to improve the vibration force of the filter screen 3.

[0041] In this embodiment, at least two guide rods 12 are fixedly installed in the inner cavity of the collection box 6. Each guide rod 12 is slidably inserted into the movable plate 11 so that the movable plate 11 will not tilt when sliding up and down, and thus will not get stuck.

[0042] In this embodiment, two opposing rotating doors 101 are rotatably mounted in the open opening of the receiving box 1 via a rotating shaft 102. The rotating shaft 102 is fixedly inserted into the rotating door 101 and rotatably connected to the receiving box 1. An L-shaped support plate 103 corresponding to the two rotating shafts 102 is fixedly installed at the bottom of the receiving box 1. The bottom of the rotating shaft 102 is rotatably connected to the L-shaped support plate 103. A toggle mechanism is provided between the rotating shaft 102 and the collection box 6. In the initial state, the two rotating doors 101 are closed (e.g., ...). Figure 5As shown, during the process of the filter screen 3 flipping to detach debris from the filter screen 3, the actuating mechanism drives the two rotating doors 101 to open. Simultaneously, during the counter-clockwise rotation of the filter screen 3 to reset, the two rotating doors 101 close under the action of the actuating mechanism, preventing debris entering the receiving box 1 from flowing back onto the filter screen 3. Since the actuating mechanism drives the two rotating doors 101 to open during the process of the filter screen 3 flipping to detach debris from the filter screen 3 (i.e., during clockwise rotation), the two open rotating doors 101 are located on the front and rear sides of the filter screen 3, respectively, thus limiting the debris and preventing it from falling into the collection box 6 from the front and rear sides of the filter screen 3.

[0043] Furthermore, two permanent magnets 9 are fixedly installed on the filter screen 3, corresponding one-to-one with the two rotating doors 101. When the two rotating doors 101 are opened, their outer surfaces are attracted to the corresponding permanent magnets 9, so that the two rotating doors 101 can be stably in the open state without shaking. Only when the filter screen 3 rotates counterclockwise will the two rotating doors 101 close under the driving action of the toggle mechanism.

[0044] In this embodiment, the actuating mechanism includes a gear 2 fixedly mounted on a rotating shaft 102 and a fixing plate 14 fixedly mounted on the inner wall of the collection box 6. The gear 2 is coaxial with the rotating shaft 102. A rubber pad 1401 that presses against the gear 2 is fixedly provided on the side of the fixing plate 14 facing the gear 2. By utilizing the elasticity and high roughness of the rubber pad 1401, the gear 2 can squeeze the rubber pad 1401 to undergo elastic deformation when it comes into contact with the rubber pad 1401. This generates a frictional force between the rubber pad 1401 and the gear 2 sufficient to drive the gear 2 to rotate. That is, during the process of the collection box 1 driving the gear 2 to rotate, the frictional force between the gear 2 and the rubber pad 1401 drives the gear 2 to rotate. The rotation of the gear 2 drives the rotating shaft 102 to rotate, and the rotation of the rotating shaft 102 drives the corresponding rotating door to rotate. Specifically, when the container 1 rotates clockwise from its initial state, the two rubber pads 1401 drive the corresponding gears 2 to rotate in opposite directions. At this time, the two rotating doors 101 open. When the gears 2 separate from the rubber pads 1401, the two rotating doors 101 open to their maximum angle. At this time, the two rotating doors 101 are attracted to the corresponding permanent magnets 9 (e.g., ...). Figure 6(As shown), the receiving box 1 then continues to rotate clockwise, allowing debris to slide from the filter screen 3 into the receiving box 1. During this process, the permanent magnet 9 and the rotating door 101 are seamlessly connected, so that both the permanent magnet 9 and the rotating door 101 play a role in limiting the debris, allowing the debris to enter the receiving box 1 smoothly. When the receiving box 1 rotates counterclockwise, the gear 2 gradually approaches the rubber pad 1401 until the gear 2 contacts the rubber pad 1401. At this time, the two gears 2 squeeze the corresponding rubber pads 1401 respectively. Under the action of friction, the two rotating doors 101 separate from the corresponding permanent magnets 9 respectively. When the filter screen 3 abuts against the baffle 604, the two rotating doors 101 close (as shown). Figure 5 (As shown).

[0045] Furthermore, a number of protruding teeth are fixedly arranged on the rubber pad 1401 to increase the friction between the gear 2 and the rubber pad 1401.

[0046] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
