Description

Technical Field

[0001] The invention relates to the technical field of end cover milling, and in particular to a CNC lathe for milling a stop surface of a product end cover and a use method thereof. Background Art

[0002] The stop surface of the product end cover refers to the surface that is in contact with the product column when the end cover is closed, such as the surface between the motor end cover and the motor housing. Since such products have certain requirements for airtightness, there is a certain matching relationship between the "combined contact" surfaces, and such matching relationship requires post-processing to achieve. In order to improve the processing quality of the end cover stop surface, milling is usually used for processing. During the milling process, a high-speed rotating tool will generate a lot of heat when milling the end cover, so milling fluid is required to cool the milling area.

However, this type of filtering pressure is high and the filter plate is prone to clogging, resulting in the amount of milling fluid re-entering the cooling system failing to reach the required amount, causing the milling area to not be fully cooled, thereby reducing the quality of the milling process.

[0019] During the cooling process, existing milling lathes use filter plates to intercept the milling debris and then allow the milling fluid to leak out. However, this type of filtering pressure is relatively high and the filter plate is prone to clogging, resulting in the amount of milling fluid re-entering the cooling system failing to reach the required amount, causing the milling area to not be fully cooled, thereby reducing the quality of the milling process.

The milling fluid in the first collecting shell 5 enters the return liquid pipe 6 through the intermediate space 102, and sinks after the debris enters the milling fluid, so as to realize the stratification of the debris and the milling fluid. Then the return liquid pipe 6 is used to absorb the middle and upper layers of the milling fluid into the cooling system, so as to avoid the blockage phenomenon that the traditional debris separation method is prone to, thereby affecting the normal cooling of the milling part. The rotating roller 7 is slidably connected with four interception plates 8 in a circular array.

[0022] like Figure 2 and Figure 8-Figure 10As shown, the discharge mechanism includes a first auger 1401, which is rotatably connected to the right side of the lower side of the machine body 1, a shell 1402 is fixedly connected to the middle of the right side of the machine body 1, an outlet is arranged at the right part of the upper side of the shell 1402, a first collection shell 5 is rotatably connected to the first auger 1401 through a fixed frame, a second auger 1403 rotatably connected to the machine body 1 is rotatably connected in the shell 1402, and the debris in the collection shell 5 is automatically discharged by using the rotating first auger 1401 and the rotating second auger 1403, thereby reducing the work intensity of the staff. A rotating column 1404 is rotatably connected to the lower right side of the body 1, and a universal joint 1405 is fixedly connected between the rotating column 1404 and the second auger 1403. A gear box 1406 is installed on the lower right side of the body 1. The gear box 1406 is an existing reversing gear box. For the convenience of description, its working principle is not described in detail here. The input shaft of the gear box 1406 is fixedly connected to the rotating column 1404, and the output shaft of the gear box 1406 is fixedly connected to the first auger 1401. A transmission component for rotating the rotating column 1404 is provided on the lower right side of the body 1.

[0023] like Figure 2 and Fig. 9 As shown, the collecting mechanism includes two support frames 1501 arranged in a front-to-back mirror image, the two support frames 1501 are fixedly connected to the left side of the machine body 1, the upper sides of the two support frames 1501 are commonly fixedly connected with a second collecting shell 1502, the second collecting shell 1502 is located below the outlet of the shell 1402, the right side of the second collecting shell 1502 is slidably connected with a baffle 1503, the baffle 1503 is made of iron, and a handle is provided on the lower right side of the baffle 1503 for easy operation by the staff, and one side of the second collecting shell 1502 is fixedly connected with Magnetic strip 1504 is a magnet, through which baffle 1503 is adsorbed, thereby reducing the operating steps of the staff in the process of transporting the debris in the first collection shell 5, reducing the work intensity of the staff, and the middle right part of the first collection shell 5 is fixedly connected with two guide members 16 arranged in front and back mirror images, the opposite sides of the two guide members 16 are inclined surfaces, and the distance between the inclined surfaces on the two guide 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 collection shell 5.

[0024] like Figure 11-13As shown, the transmission assembly includes a transmission shaft 1701, which is rotatably connected to the lower right part of the body 1, and the transmission shaft 1701 and the rotating shaft 1102 are driven by a pulley belt. The front end of the transmission shaft 1701 is fixedly connected with a first transmission plate 1702, and the rotating column 1404 is provided with a second transmission plate 1703. The rotating first transmission plate 1702 contacts the second transmission plate 1703 and drives them to rotate together, and the outer side surface of the first transmission plate 1702 and the outer side surface of the second transmission plate 1703 are both inclined surfaces, which are used to increase the contact area between the two and increase the stability during rotation.

[0025] When the present invention is required to perform milling processing on the end cover 101, the staff opens the clamp 4 through the control panel, and then places the end cover 101 on the clamp 4. The staff then controls the clamp 4 through the control panel to clamp the end cover 101, and then starts the tool alignment step (tool alignment is an existing step, and for the sake of ease of description, it will not be described in detail here). After the preparatory work is completed, the staff starts the power component 2, the cutter disc 3, the cooling system and the drive motor 1101 through the control panel, and the output shaft of the drive motor 1101 starts to rotate counterclockwise (in the normal direction). At this time, the present invention mills the end cover 101 according to a predetermined procedure. During the process, the cooling system absorbs the milling fluid in the first collecting shell 5 through the return liquid pipe 6, and cools the milling part of the end cover 101.

[0026] During the milling process, the debris generated on the end cover 101 falls downward into the first collecting shell 5 and gradually settles downward. During the process, the debris and the milling fluid are automatically stratified, that is, the debris sinks to the bottom of the first collecting shell 5, and the return liquid pipe 6 absorbs the milling fluid in the middle and upper parts of the first collecting shell 5, so as to "filter" the debris in the milling fluid, preventing the traditional filtering method from directly using the filter net to filter a large amount of debris, which is prone to blockage, resulting in the return liquid pipe 6 absorbing the milling fluid in the first collecting shell 5 The amount required by the cooling system cannot be absorbed, resulting in the milling part of the end cover 101 not being fully cooled, thereby reducing the quality of the milling process.

[0027] In order to improve the cooling effect, the rotating interception 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 fine debris in the milling fluid from affecting 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, and the rotating shaft 1102 drives the rotating roller 7 to rotate counterclockwise, and the rotating roller 7 rotates relative to the first collecting shell 5, and the rotating roller 7 drives the four The intercepting plate 8, the four first sliding rods 9 and the four first elastic elements 10 rotate counterclockwise together, and the limiting column of the first sliding rod 9 begins to slide in the adjacent limiting groove 1103 (for ease of understanding, the movement of the upper first sliding rod 9 is taken as an example), and the two limiting columns of the upper first sliding rod 9 slide in the adjacent second arc groove 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 squeezing effect of the limiting column in the adjacent middle groove 11033 The first sliding rod 9 drives the adjacent intercepting plate 8 to move together through the adjacent first elastic element 10, and 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 small debris in the middle space 102, until the limiting column on the first sliding rod 9 enters the first arc groove 11031 and no longer extends out, at which time the intercepting plate 8 (moving to the left) and the middle space 102 are in contact with each other. The inner wall of the first collecting shell 5 is in contact with the intermediate space 102. As the rotating roller 7 continues to rotate counterclockwise, the interception plate 8 continuously intercepts the fine debris in the intermediate space 102, so as to ensure the cleanliness of the milling fluid absorbed by the return liquid pipe 6, and prevent the fine debris in the milling fluid from overcoming gravity and moving upward into the return liquid pipe 6 under the suction action of the return liquid pipe 6, thereby interfering with the subsequent cooling process. At the same time, the debris in the flow also hits the end cover 101, causing tiny scratches or splashing on the end cover 101, thereby reducing the milling quality of the end cover 101.

[0028] In the process that the first sliding rod 9 rotates counterclockwise with the rotating roller 7, when the intercepting plate 8 (moved to the lower side) contacts the first blocking rod 12, as the rotating roller 7 continues to rotate counterclockwise, the intercepting plate 8 on the lower side deflects in the clockwise direction (in the normal direction), and the adjacent first elastic element 10 is deformed. When the intercepting plate 8 on the lower side rotates counterclockwise with the rotating roller 7 and passes the first blocking rod 12, the intercepting plate 8 on the lower side begins to quickly reset (i.e., reverse deflection) under the action of the torsion of the adjacent first elastic element 10, and then the intercepting plate 8 that has quickly reset contacts the second blocking rod 13, and the intercepting plate 8 stops quickly, so that the debris intercepted on the interception plate 8 is separated under the action of inertia, ensuring the normal milling fluid passability of the interception plate 8, and the interception plate 8 is deflected clockwise again under the action of the second baffle 13 blocking, and as the rotating roller 7 rotates counterclockwise, the interception plate 8 is reset again, and the milling fluid in the adjacent area is pushed to the right, so that the milling fluid moves to the right, and the debris on the left is taken away by the milling fluid moving to the right. In the process, the flowing milling fluid is guided toward the center by two guide members 16, so that the debris gathers to the middle of the lower inner side of the first collecting shell 5, thereby facilitating the subsequent discharge of the debris.

[0029] During the counterclockwise rotation of the rotating roller 7, when the limiting column on the first sliding rod 9 (moving to the lower right side) enters the middle groove 11033 on the right side, the limiting column on the lower right first sliding rod 9 begins to move toward the direction close to the axis of the rotating roller 7 under the extrusion of the adjacent middle groove 11033, and the first sliding rod 9 drives the parts on it to move together, and the intercepting plate 8 begins to retract. When the limiting column of the first sliding rod 9 (moving to the right side) enters the adjacent second arc groove 11032, the intercepting plate 8 completely retracts, thereby continuously intercepting fine debris in the milling fluid in the intermediate space 102 through a cyclic motion.

[0030] During the counterclockwise rotation of the rotating shaft 1102, the rotating shaft 1102 transmits power to the transmission shaft 1701 through the pulley belt, and the transmission shaft 1701 starts to rotate counterclockwise (in the front view), and the transmission shaft 1701 drives the first transmission plate 1702 to rotate counterclockwise together, and the first transmission plate 1702 drives the second transmission plate 1703 to rotate clockwise (in the top view), and the second transmission plate 1703 drives the rotating column 1404 to rotate clockwise together, and the rotating column 1404 drives the input shaft and the universal joint 1405 of the gear box 1406 to rotate together, and the output shaft of the gear box 1406 drives the second transmission plate 1703 to rotate clockwise (in the top view). An auger 1401 rotates together, and the rotating first auger 1401 transports the debris in the adjacent area of ​​the first collecting shell 5 to the right. During the process, the universal joint 1405 drives the second auger 1403 to rotate together, and 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 continues to move upward along the outer shell 1402, and finally the debris moves upward to the outlet of the outer shell 1402 and falls into the second collecting shell 1502, thereby completing the automatic removal of the debris generated by milling and reducing the workload of the staff.

[0031] As the milling time increases, the debris in the second collection shell 1502 becomes more and more. When the second collection shell 1502 is full of debris, the staff lifts the baffle 1503 upwards by the handle, and the baffle 1503 begins to move upward and is gradually attracted by the magnetic strip 1504. When the baffle 1503 moves upwards and contacts with 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 uses a transfer tool (trolley) to transfer the debris. Then the staff resets the baffle 1503. When the milling work is completed, the staff turns off the power component 2, the cutter disc 3, the cooling system and the drive motor 1101 through the control panel.

[0032] In Example 1, the rotating column 1404 and the second transmission plate 1703 are fixedly connected, while in Example 2, the rotating column 1404 and the second transmission plate are splined to change the motion state of the second transmission plate 1703, so that it rotates intermittently to reduce energy consumption.

[0033] Embodiment 2: Based on embodiment 1, Figure 11-Figure 14As shown, it also includes an adjustment mechanism for making the rotating column 1404 intermittently move, the adjustment mechanism is arranged on the right side of the body 1, the adjustment mechanism includes a second sliding rod 1801, the second sliding rod 1801 is slidably connected to the right side of the body 1, the rotating column 1404 is splined with the second transmission plate 1703, the second sliding rod 1801 is slidably connected to the first collection shell 5, one end of the second sliding rod 1801 is fixedly connected to a floating plate 1802, the density of the floating plate 1802 is less than the density of the cooling medium, and a second elastic element 1803 is fixedly connected between the second sliding rod 1801 and the first collection shell 5, and the second elastic element 180 3 is a tension spring, which is used to reset the second sliding rod 1801. The second transmission plate 1703 is rotatably connected to the moving ring 1804. An intermediate rod 1805 slidably connected to the body 1 is fixedly connected between the moving ring 1804 and the second sliding rod 1801. The liquid level of the milling fluid rises due to the accumulation of debris in the first collecting shell 5, so that the floating plate 1802 moves upward, and finally the second transmission plate 1703 contacts the first transmission plate 1702 and rotates, and then the debris accumulated in the first collecting shell 5 is discharged, so as to avoid long-term rotation of the first auger 1401 and the second auger 1403, which leads to high energy consumption.

[0034] In order to reduce the energy consumption of the device, the middle rod 1805 is moved up and down to drive the second transmission plate 1703 to move up and down together, thereby changing the contact state of the second transmission plate 1703 and the first transmission plate 1702, so that the first auger 1401 and the second auger 1403 are rotated intermittently, and the first auger 1401 and the second auger 1403 are prevented from rotating for a long time and causing power waste. The detailed steps are as follows: during the milling process, as the milling time increases, the debris continues to accumulate in the first collecting shell 5, that is, the liquid level of the milling fluid in the first collecting shell 5 continues to rise, and the floating plate 1802 begins to move upward under the action of buoyancy, and the floating plate 1802 drives the second sliding rod 1801 to move upward together, and the second sliding rod 1801 and the body 1 and the first collecting shell 5 all slide relative to each other. The second elastic element 1803 is stretched and the second sliding The movable rod 1801 drives the middle rod 1805 to move upward together, and the middle rod 1805 drives the moving ring 1804 to move upward together, and the moving ring 1804 drives the second transmission plate 1703 to move upward together. When the second transmission plate 1703 moves upward to contact with the first transmission plate 1702, the rotating first transmission plate 1702 drives the second transmission plate 1703 to rotate together, and then the first auger 1401 and the second auger 1403 start to rotate and discharge the debris in the device, and 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 accumulate debris in the first collecting shell 5 to the required discharge degree and then automatically discharge the material, thereby reducing the rotation time of the first auger 1401 and the second auger 1403 and reducing energy consumption.

[0035] As the debris in the first collecting shell 5 is continuously discharged, the liquid level of the milling fluid in the first collecting shell 5 continues to drop, the buoyancy of the float plate 1802 decreases, and the second sliding rod 1801 begins to move downward under the action of the pulling force of the second elastic element 1803. The second sliding rod 1801 drives the middle 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.

[0036] Embodiment 3: Based on embodiment 2, Figure 1-Figure 14 As shown, a method for using a CNC lathe for milling a stop surface of a product end cover comprises the following steps: S1: After clamping the end cover 101 in the fixture 4, the power component 2, the cutter head 3, the cooling system and the drive motor 1101 are started to start milling the end cover 101; S2: During the rotation process, the upper limit post of the first sliding rod 9 always moves along the adjacent limit slot 1103, and the upper limit post of the adjacent first sliding rod 9 is limited by the limit slot 1103 so that the adjacent intercepting plate 8 extends out in the middle space 102, thereby intercepting the fine debris in the middle space 102; S3: The first stopper 12 blocks the adjacent interception plate 8 and causes it to deflect, so that the interception plate 8 is rapidly reset after passing through the first stopper 12 and then stops suddenly when contacting the second stopper 13, so that the debris intercepted on the interception plate 8 is separated under the action of inertia; S4: The change in the liquid level of the milling fluid in the first collecting shell 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 rotate only when the debris in the first collecting shell 5 needs to be discharged.
