Description

Technical Field

[0001] The present invention relates to the technical field of end - cover milling, and in particular to a numerical control lathe for milling the stop surface of a product end - cover and its usage method. Background Art

[0002] The stop surface of a product end - cover refers to the surface that comes into contact with the product cylinder when the end - cover is closed. For example, the surface that comes into contact between the motor end - cover and the motor housing. Since such products have certain requirements for airtightness, there is a certain mating relationship between the "contacting" surfaces, and such a mating relationship needs to be achieved through later processing. In order to improve the machining quality of the end - cover stop surface, milling is usually used for processing. During the milling process, a large amount of heat is generated when the high - speed rotating tool mills the end - cover, so a milling fluid is required to cool the milling area.

[0003] In the existing milling lathes, during the cooling process, a filter plate is used to intercept the chips milled out, and then the milling fluid leaks downward. However, in this way, the filtering pressure is high, and the filter plate is prone to clogging, resulting in the amount of milling fluid re - entering the cooling system not reaching the required amount, so that the milling area cannot be fully cooled, reducing the quality of the milling process.

[0015] S1: Clamp the end cover part on the fixture, then start the power component, the cutter head, the cooling system and the drive motor, and start milling the end cover part.

[0016] S2: During the rotation of the first sliding rod, the limit posts thereon always move along the adjacent limit grooves, and the adjacent intercepting plates are made to extend into the intermediate space by the limitation of the limit grooves on the limit posts of the adjacent first sliding rods, so as to intercept the fine debris in the intermediate space.

[0017] S3: The first stop rod blocks the adjacent intercepting plate and causes it to deflect, so that the intercepting plate makes an emergency stop when contacting the second stop rod during the rapid reset process after passing the first stop rod, so that the debris intercepted on the intercepting plate falls off under the action of inertia.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: By directly introducing the debris into the milling fluid and then separating it, the return pipe sucks the milling fluid in the upper-middle part of the first collection shell, so as to "filter" the debris in the milling fluid, preventing the traditional filtering method from easily getting blocked when directly using a filter screen to filter a large amount of debris, resulting in the amount of milling fluid sucked by the return pipe into the first collection shell not reaching the amount required by the cooling system, causing the milling area of the end cover part not to be sufficiently cooled and reducing the quality of the milling process; Using the rotating intercepting plate to continuously intercept the fine debris in the intermediate space, so as to ensure the cleanliness of the milling fluid sucked by the return pipe, avoiding the fine debris in the milling fluid overcoming gravity and moving upward into the return pipe under the suction of the return pipe, thus interfering with the subsequent cooling process, and the flowing debris impacts the end cover part, resulting in micro-scratches or erosion on the end cover part and reducing the milling quality of the end cover part; By blocking the adjacent intercepting plates with the first blocking rod to make them deflect, and then using the second blocking rod to block the intercepting plate that quickly resets, the moving speed of the intercepting plate is rapidly reduced, so that the fine debris intercepted on the intercepting plate is separated by inertia, thereby ensuring the passing rate of the milling fluid in the area near the intercepting plate; Identifying the accumulation degree of the debris in the first collection shell by the change of the liquid level of the milling fluid in the first collection shell, and then driving the second sliding rod to move upward together with the floating plate, making the second transmission plate contact the first transmission plate, and then making the first auger and the second auger rotate, so as to intermittently discharge the accumulated debris in the first collection shell, avoiding high energy consumption caused by the long-term rotation of the first auger and the second auger.

Detailed implementation manners

[0035] Among them, the drawings are only for illustrative purposes, showing only schematic diagrams, rather than actual diagrams, and should not be construed as a limitation to this patent. To better illustrate the embodiments of the present invention, some structures in the drawings are omitted, enlarged or reduced, and do not represent the dimensions of the actual product. For those skilled in the art, some well-known structures and descriptions in the drawings may be omitted and can be understood.

[0036] In the existing milling lathe, during the cooling process, a filter plate is used to intercept the chips produced by milling, and then the milling fluid leaks downward. However, the filtration pressure of this method is relatively high, and the filter plate is prone to clogging, resulting in the amount of milling fluid re-entering the cooling system not reaching the required amount, so that the milling area cannot be sufficiently cooled, reducing the quality of milling processing.

[0037] Embodiment 1: A numerically controlled lathe for milling the stop surface of a product end cover, as Figures 1-5 shown, including a machine body 1. A control panel is installed at the upper right part of the front side of the machine body 1. A power component 2 is installed on the upper part of the machine body 1. The power component 2 is equipped with a cutter head 3. A cooling system is arranged on the upper part of the machine body 1 (the cooling system is a prior art and will not be described in detail here for the convenience of narration). A number of cutters are installed on the cutter head 3. The cutters are milling cutters, turning tools, cutoff tools, etc. The cutter head 3 moves automatically according to a predetermined program (changing tools). A clamp 4 for clamping the end cover part 101 is arranged on the upper side of the machine body 1. A first collection shell 5 is fixedly connected to the lower part inside the machine body 1. A cooling medium is filled in the first collection shell 5. The cooling medium is milling fluid and is used to cool the milling area. A return pipe 6 is connected between the cooling system of the machine body 1 and the first collection shell 5. The height of the connection between the return pipe 6 and the first collection shell 5 is lower than the liquid level of the cooling medium in the first collection shell 5. A rotating roller 7 is rotatably connected to the left side inside the first collection shell 5. There is an intermediate space 102 between the rotating roller 7 and the first collection shell 5. The milling fluid in the first collection shell 5 enters the return pipe 6 through the intermediate space 102. After the chips enter the milling fluid and sink, the separation of the chips and the milling fluid is realized. Then, the upper and middle layers of the milling fluid are sucked into the cooling system by the return pipe 6, avoiding the phenomenon of easy clogging in the traditional chip separation method, thus affecting the normal cooling of the milling area. Four intercepting plates 8 are slidably connected to the rotating roller 7. During the movement, the intercepting plates 8 contact the lower left part of the first collection shell 5, thereby intercepting the fine chips in the intermediate space 102. A telescopic mechanism for moving all four intercepting plates 8 is arranged on the left side of the first collection shell 5. A discharging mechanism for discharging the chips in the first collection shell 5 is arranged at the lower part on the right side of the machine body 1. A collection mechanism for collecting the collected objects is arranged on the right side of the machine body 1.

[0038] As Figures 4-7As shown, the telescopic mechanism includes four first sliding rods 9 arranged in an annular array. The four first sliding rods 9 are all slidably connected to the rotating roller 7. Limit posts are provided on the back sides of the first sliding rods 9. A first elastic element 10 is fixedly connected between the first sliding rod 9 and the adjacent intercepting plate 8. The first elastic element 10 is an elastic rubber strip for resetting the adjacent intercepting plates 8. A driving motor 1101 is installed at the left rear side inside the machine body 1. The output shaft of the driving motor 1101 is fixedly connected to a rotating shaft 1102 fixedly connected to the rotating roller 7. Two limit grooves 1103 arranged in a front-back mirror image are provided at the left part inside the first collection shell 5. The limit posts of the first sliding rod 9 are in limit cooperation with the adjacent limit grooves 1103. The limit groove 1103 is composed of a first arc groove 11031, a second arc groove 11032, and two intermediate grooves 11033 arranged in a left-right mirror image, and the connection sequence is first arc groove 11031 - intermediate groove 11033 - second arc groove 11032 - intermediate groove 11033, and the radius of the first arc groove 11031 is greater than the radius of the second arc groove 11032. The intermediate groove 11033 is a straight groove. By limiting the limit posts of the adjacent first sliding rods 9 through the limit grooves 1103, the adjacent first sliding rods 9 and the parts thereon are moved. A first stop rod 12 and a second stop rod 13 are fixedly connected to the lower left side inside the first collection shell 5. The first stop rod 12 is located to the left of the second stop rod 13. Both the first stop rod 12 and the second stop rod 13 are located in the intermediate space 102. Both the first stop rod 12 and the second stop rod 13 are in limit cooperation with the adjacent intercepting plates 8. By using the limit of the first stop rod 12 on the adjacent intercepting plates 8, the adjacent intercepting plates 8 are deflected. Then, when the adjacent intercepting plates 8 are reset through the adjacent first elastic elements 10, they hit the second stop rod 13, so that the fine debris on the intercepting plates 8 falls off under the action of inertia, ensuring the permeability of the intercepting plates 8.

[0039] As Figure 2 and Figures 8-10As shown in the figure, the discharging mechanism includes a first auger 1401. The first auger 1401 is rotatably connected to the right side of the lower side of the machine body 1. The middle part of the right side of the machine body 1 is fixedly connected with a housing 1402. An outlet is arranged at the upper right part of the housing 1402. The first collecting shell 5 is rotatably connected to the first auger 1401 through a fixing frame. A second auger 1403 rotatably connected to the machine body 1 is rotatably connected in the housing 1402. The rotating first auger 1401 and the rotating second auger 1403 are used to automatically discharge the debris in the collecting shell 5, reducing the working intensity of the staff. A rotating column 1404 is rotatably connected to the lower right side of the machine body 1. A universal joint 1405 is fixedly connected between the rotating column 1404 and the second auger 1403. A gearbox 1406 is installed on the lower right side of the machine body 1. The gearbox 1406 is an existing reversing gearbox. For the convenience of description, its working principle will not be elaborated here too much. The input shaft of the gearbox 1406 is fixedly connected to the rotating column 1404, and the output shaft of the gearbox 1406 is fixedly connected to the first auger 1401. A transmission assembly for rotating the rotating column 1404 is arranged on the lower right side of the machine body 1.

[0040] As Figure 2 and Figure 9 shown in the figure, the collecting mechanism includes two support frames 1501 arranged in a front-back mirror image. Both of the two support frames 1501 are fixedly connected to the left side of the machine body 1. A second collecting shell 1502 is fixedly connected to the upper sides of the two support frames 1501. The second collecting shell 1502 is located below the outlet of the housing 1402. A baffle 1503 is slidably connected to the right side of the second collecting shell 1502. The baffle 1503 is made of iron. A handle is arranged at the lower right side of the baffle 1503, which is convenient for the staff to operate. A magnetic strip 1504 is fixedly connected to one side of the second collecting shell 1502. The magnetic strip 1504 is a magnet. The baffle 1503 is adsorbed by the magnetic strip 1504, thereby reducing the operation steps of the staff during the process of transporting the debris in the first collecting shell 5 and reducing the working intensity of the staff. Two guiding members 16 arranged in a front-back mirror image are fixedly connected to the middle right part of the first collecting shell 5. The opposite sides of the two guiding members 16 are both inclined surfaces, and the distance between the inclined surfaces on the two guiding members 16 gradually decreases from the upper left to the lower right, which is used to guide the debris to the middle part of the first collecting shell 5.

[0041] As Figures 11-13As shown in the figure, the transmission assembly includes a transmission shaft 1701. The transmission shaft 1701 is rotatably connected to the lower right part of the machine body 1. A belt pulley belt drive is provided between the transmission shaft 1701 and the rotating shaft 1102. A first transmission plate 1702 is fixedly connected to the front end of the transmission shaft 1701. A second transmission plate 1703 is provided on the rotating column 1404. The rotation of the first transmission plate 1702 drives the second transmission plate 1703 to rotate together by contacting it. The outer sides of both the first transmission plate 1702 and the second transmission plate 1703 are inclined surfaces, which are used to increase the contact area between the two and enhance the stability during the rotation process.

[0042] When it is necessary to use the present invention to mill the end cover part 101, the staff opens the fixture 4 through the control panel. Then, the staff places the end cover part 101 on the fixture 4, and then the staff controls the fixture 4 to clamp the end cover part 101 through the control panel. Then, the tool setting step is started (tool setting is an existing step and will not be elaborated too much here for the convenience of description). After the preparatory work is completed, the staff starts the power component 2, the cutter head 3, the cooling system, and the drive motor 1101 through the control panel. The output shaft of the drive motor 1101 starts to rotate counterclockwise (in the front view direction). At this time, the present invention mills the end cover part 101 according to the established program. During the process, the cooling system sucks the milling fluid in the first collection shell 5 through the return liquid pipe 6 and cools the milling area of the end cover part 101.

[0043] During the milling process, the debris generated on the end cover part 101 falls downward into the first collection shell 5 and gradually settles downward. During this process, the debris and the milling fluid are automatically stratified, that is, the debris sinks to the bottom of the first collection shell 5, while the return liquid pipe 6 sucks the milling fluid in the upper and middle parts of the first collection shell 5, so as to "filter" the debris in the milling fluid, preventing the traditional filtering method from directly using a filter screen to filter a large amount of debris, which is prone to blockage, resulting in the amount of milling fluid sucked by the return liquid pipe 6 from the first collection shell 5 not reaching the amount required by the cooling system, so that the milling area of the end cover part 101 cannot be fully cooled, reducing the quality of the milling process.

[0044] To improve the cooling effect, a rotating intercepting plate 8 is used to filter the fine debris in the milling fluid, so as to ensure the cleanliness of the milling fluid entering the return pipe 6 and avoid the influence of the fine debris in the milling fluid on the normal milling process. The detailed steps are as follows. During the counterclockwise rotation of the output shaft of the driving motor 1101, the output shaft of the driving motor 1101 drives the rotating shaft 1102 to rotate counterclockwise together. The rotating shaft 1102 drives the rotating roller 7 to rotate counterclockwise together. The rotating roller 7 rotates relative to the first collecting shell 5. The rotating roller 7 drives the four intercepting plates 8, the four first sliding rods 9 and the four first elastic elements 10 to rotate counterclockwise together. The limiting columns of the first sliding rod 9 start to slide in the adjacent limiting grooves 1103 (for the sake of easy understanding, the movement of the upper first sliding rod 9 is taken as an example). The two limiting columns of the upper first sliding rod 9 slide in the adjacent second arc-shaped grooves 11032 respectively. As the rotating roller 7 continues to rotate counterclockwise, when the limiting column of the upper first sliding rod 9 enters the adjacent middle groove 11033 on the left, the limiting column starts to move in the direction away from the axis of the rotating roller 7 under the extrusion of the adjacent middle groove 11033. The two adjacent and mirror-image arranged limiting columns jointly drive the adjacent first sliding rod 9 to move together. The first sliding rod 9 drives the adjacent intercepting plate 8 to move together through the adjacent first elastic element 10. The intercepting plate 8 slides relative to the rotating roller 7, that is, the intercepting plate 8 gradually extends out of the rotating roller 7 and intercepts the fine debris in the middle space 102 until the limiting column on the first sliding rod 9 enters the first arc-shaped groove 11031 and no longer extends. At this time, the intercepting plate 8 (moved to the left) contacts the inner wall of the first collecting shell 5 at the middle space 102. As the rotating roller 7 continues to rotate counterclockwise, the intercepting plate 8 continuously intercepts the fine debris in the middle space 102, so as to ensure the cleanliness of the milling fluid sucked by the return pipe 6 and avoid the fine debris in the milling fluid overcoming gravity and moving upward into the return pipe 6 under the suction of the return pipe 6, thus interfering with the subsequent cooling process. At the same time, the flowing debris also impacts the end cover part 101, resulting in micro-scratches or sputtering on the end cover part 101 and reducing the milling quality of the end cover part 101.

[0045] During the counterclockwise rotation of the first sliding rod 9 with the rotating roller 7, when the intercepting plate 8 (which has moved to the lower side) contacts the first stop rod 12, as the rotating roller 7 continues to rotate counterclockwise, the lower intercepting plate 8 deflects clockwise (in the front view direction), and the adjacent first elastic element 10 deforms. After the lower intercepting plate 8 rotates counterclockwise past the first stop rod 12 with the rotating roller 7, the lower intercepting plate 8 starts to quickly reset (i.e., deflects in the reverse direction) under the torsional force of the adjacent first elastic element 10. Then, during the rapid reset, the intercepting plate 8 contacts the second stop rod 13, and the intercepting plate 8 quickly stops, so that the debris intercepted on the intercepting plate 8 detaches under the action of inertia, ensuring the normal passing of the milling fluid through the intercepting plate 8. The intercepting plate 8 deflects clockwise again under the blocking action of the second stop rod 13. As the rotating roller 7 rotates counterclockwise, the intercepting plate 8 resets again and deflects the milling fluid in the adjacent area to the right, causing the milling fluid to move to the right and using the milling fluid moving to the right to carry the debris on the left away. During this process, the flowing milling fluid is guided towards the middle by the two guiding members 16, causing the debris to gather in the middle of the lower side of the first collecting shell 5, thus facilitating the subsequent discharge of the debris.

[0046] During the counterclockwise rotation of the rotating roller 7, when the limiting post on the first sliding rod 9 (which has moved to the lower right) enters the right middle groove 11033, the limiting post on the lower right first sliding rod 9 starts to move towards the axis of the rotating roller 7 under the extrusion of the adjacent middle groove 11033. The first sliding rod 9 drives the parts on it to move together, and the intercepting plate 8 starts to retract. When the limiting post of the first sliding rod 9 (which has moved to the right) enters the adjacent second arc groove 11032, the intercepting plate 8 completely retracts, and this cyclic motion continuously intercepts the fine debris in the milling fluid in the middle space 102.

[0047] During the counterclockwise rotation of the rotating shaft 1102, the rotating shaft 1102 transmits power to the transmission shaft 1701 through the pulley belt. The transmission shaft 1701 starts to rotate counterclockwise (in the front view direction). The transmission shaft 1701 drives the first transmission plate 1702 to rotate counterclockwise together. The first transmission plate 1702 drives the second transmission plate 1703 to rotate clockwise (in the top view direction). The second transmission plate 1703 drives the rotating column 1404 to rotate clockwise together. The rotating column 1404 drives the input shaft of the gearbox 1406 and the universal joint 1405 to rotate together. The output shaft of the gearbox 1406 drives the first auger 1401 to rotate together. The rotating first auger 1401 transports the debris in adjacent areas in the first collection shell 5 to the right. During this process, the universal joint 1405 drives the second auger 1403 to rotate together. The rotating second auger 1403 transports the debris on the right side of the first auger 1401 upward. As the second auger 1403 continues to rotate, the debris continuously moves upward along the housing 1402. Finally, the debris moves upward to be discharged from the outlet of the housing 1402 and falls into the second collection shell 1502, thus completing the automatic removal of the debris generated by milling and reducing the working intensity of the staff.

[0048] As the milling time increases, there is more and more debris in the second collection shell 1502. When the second collection shell 1502 is full of debris, the staff lifts the baffle 1503 upward through the handle. The baffle 1503 starts to move upward and is gradually attracted by the magnetic strip 1504. When the baffle 1503 moves upward to contact the magnetic strip 1504, the magnetic strip 1504 completely attracts the baffle 1503. Then the staff removes the debris in the second collection shell 1502 and transfers the debris using a transfer tool (a trolley). Then the staff can reset the baffle 1503. When the milling work is completed, the staff can turn off the power component 2, the cutter head 3, the cooling system, and the drive motor 1101 through the control panel.

[0049] In Embodiment 1, the rotating column 1404 is fixedly connected to the second transmission plate 1703. In Embodiment 2, the rotating column 1404 is spline-connected to the second transmission plate, thereby changing the motion state of the second transmission plate 1703 and making its intermittent rotation reduce energy consumption.

[0050] Embodiment 2: On the basis of Embodiment 1, as Figures 11-14As shown in the figure, it further includes an adjusting mechanism for intermittently moving the rotating column 1404. The adjusting mechanism is arranged on the right side of the machine body 1. The adjusting mechanism includes a second sliding rod 1801. The second sliding rod 1801 is slidably connected to the right side of the machine body 1. The rotating column 1404 is splined to the second transmission plate 1703. The second sliding rod 1801 is slidably connected to the first collecting shell 5. One end of the second sliding rod 1801 is fixedly connected with a floating plate 1802. The density of the floating plate 1802 is less than the density of the cooling medium. A second elastic element 1803 is fixedly connected between the second sliding rod 1801 and the first collecting shell 5. The second elastic element 1803 is a tension spring for resetting the second sliding rod 1801. The second transmission plate 1703 is rotatably connected with a moving ring 1804. A middle rod 1805 slidably connected to the machine body 1 is fixedly connected between the moving ring 1804 and the second sliding rod 1801. As the debris accumulates in the first collecting shell 5, the liquid level of the milling fluid rises, so that the floating plate 1802 moves upward. Finally, the second transmission plate 1703 contacts the first transmission plate 1702 and rotates. Then, the debris accumulated in the first collecting shell 5 is discharged externally, avoiding high energy consumption caused by the long-term rotation of the first auger 1401 and the second auger 1403.

[0051] In order to reduce the energy consumption of the device, the second transmission plate 1703 is driven to move up and down together by the up and down movement of the middle rod 1805, so as to change the contact state between the second transmission plate 1703 and the first transmission plate 1702, so that the first auger 1401 and the second auger 1403 rotate intermittently, avoiding power waste caused by the long-term continuous rotation of the first auger 1401 and the second auger 1403. The detailed steps are as follows. During the milling process, as the milling time increases, the debris continuously accumulates in the first collecting shell 5, that is, the liquid level of the milling fluid in the first collecting shell 5 continuously rises. The floating plate 1802 begins to move upward under the action of buoyancy. The floating plate 1802 drives the second sliding rod 1801 to move upward together. The second sliding rod 1801 and the machine body 1 both slide relative to the first collecting shell 5. The second elastic element 1803 is stretched. The second sliding rod 1801 drives the middle rod 1805 to move upward together. The middle rod 1805 drives the moving ring 1804 to move upward together. The moving ring 1804 drives the second transmission plate 1703 to move upward together. When the second transmission plate 1703 moves upward to contact the first transmission plate 1702, the rotating first transmission plate 1702 drives the second transmission plate 1703 to rotate together. Then, the first auger 1401 and the second auger 1403 start to rotate and discharge the debris in the device externally. The accumulation of debris in the first collecting shell 5 causes the liquid level of the milling fluid to rise and drives the floating plate 1802 to move upward, so that the first auger 1401 and the second auger 1403 automatically discharge the material after the debris in the first collecting shell 5 accumulates to the required degree for external discharge, thereby reducing the rotation time of the first auger 1401 and the second auger 1403 and reducing the energy consumption.

[0052] As the debris in the first collection housing 5 is continuously discharged, the liquid level of the milling fluid in the first collection housing 5 continuously drops, the buoyancy force on the floating plate 1802 decreases, and the second sliding rod 1801 begins to move downward under the pulling force of the second elastic element 1803. The second sliding rod 1801 drives the intermediate rod 1805 and the parts thereon to move downward together, and the second transmission plate 1703 moves downward and loses contact with the first transmission plate 1702.

[0053] Embodiment 3: On the basis of Embodiment 2, as Figures 1-14 shown, a method for using a numerically controlled lathe for milling the stop surface of a product end cover includes the following steps:

[0054] S1: Clamp the end cover part 101 on the fixture 4, then start the power component 2, the cutter head 3, the cooling system, and the drive motor 1101, and start milling the end cover part 101.

[0055] S2: During the rotation of the first sliding rod 9, the upper limit posts thereon always move along the adjacent limit grooves 1103, and the adjacent intercepting plates 8 are extended into the intermediate space 102 by using the limitation of the upper limit posts on the adjacent first sliding rod 9 by the limit grooves 1103, so as to intercept the fine debris in the intermediate space 102.

[0056] S3: The first stop rod 12 blocks the adjacent intercepting plate 8 and causes it to deflect, so that the intercepting plate 8 makes an emergency stop when contacting the second stop rod 13 during the rapid reset process after passing the first stop rod 12, so that the debris intercepted on the intercepting plate 8 breaks away under the action of inertia.

[0057] S4: The change in the liquid level of the milling fluid in the first collection housing 5 changes the height of the floating plate 1802, thereby determining whether the first auger 1401 and the second auger 1403 rotate, so that the first auger 1401 and the second auger 1403 only rotate when it is necessary to discharge the debris in the first collection housing 5.
