Description

Technical Field

[0001] This utility model relates to a cutting fluid circulation mechanism for milling machines used in the machining of ball cage cages, and belongs to the technical field of cutting fluid recovery. Background Technology

[0002] In the machining process of ball cages, milling machines are commonly used key equipment. They use high-speed rotating cutting tools to cut the workpiece to obtain a ball cage structure that meets the accuracy requirements. Cutting fluid plays a crucial role in this machining process. It can effectively cool the high-speed rotating cutting tools and the ball cage being machined, preventing the tool wear from being accelerated and the machining accuracy of the workpiece from decreasing due to high temperature.

[0003] Chinese patent CN220944400U discloses a lathe cutting fluid circulation device, including a collection unit, a first filter assembly, and a liquid circulation assembly. The collection unit includes a cutting fluid collection tank and a chip collection tank. The cutting fluid collection tank has an open top for collecting filtered cutting fluid, and the chip collection tank collects filtered chips. The first filter assembly is detachably installed at the open top of the cutting fluid collection tank. The first filter assembly includes an inclined first filter structure for filtering the cutting fluid and guiding the chips into the chip collection tank. The liquid circulation assembly is connected to the cutting fluid collection tank and guides the liquid in the cutting fluid collection tank to the lathe turning position.

[0004] In the aforementioned patent, metal shavings are filtered by an inclined filter screen. However, in practical applications, this filtration method has obvious defects. Because the metal shavings are extremely irregular in shape and often have burrs, they are very easy to get stuck on the inclined filter screen and have difficulty sliding off smoothly. As processing time goes by, a large amount of metal shavings accumulate on the filter screen, which will significantly reduce the effective filtration area of ​​the filter screen. Operators have to frequently stop the machine to clean the filter screen, which not only increases labor costs but also seriously reduces the continuity of production. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a milling machine cutting fluid circulation mechanism for ball cage cage machining, which solves the problem of irregular metal chips generated during ball cage cage machining getting stuck and accumulating on the filter screen.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a milling machine cutting fluid circulation mechanism for processing ball cage retainers, characterized in that it includes: a recovery box, a liquid storage chamber is opened at the midpoint of the recovery box, and a slag discharge channel is opened in the annular shape inside the recovery box. The recovery box is provided with a conical filter plate, and an L-shaped fixing frame is fixed on the top of the recovery box. A rotating sleeve is provided through the L-shaped fixing frame via a bearing, and a drive rod is provided inside the rotating sleeve. The drive rod passes through the midpoint of the conical filter plate and is fixedly connected to it. Both the drive rod and the inner wall of the rotating sleeve are polygonal. A top plate is fixed on the top of the drive rod, and columns are fixed at both ends of the bottom of the top plate. Rollers are provided at the bottom of the columns. A wedge plate is fixed on the top of the L-shaped fixing frame, and the wedge plate is located on both sides of the rotating sleeve. The top of the L-shaped fixing frame is equipped with a drive mechanism for rotating the rotating sleeve.

[0007] Preferably, the conical filter disc is located above the liquid storage tank, and the diameter of the conical filter disc is larger than the inner diameter of the liquid storage tank.

[0008] Preferably, a shock-absorbing pad is also fixed to the top of the L-shaped fixing frame, and the shock-absorbing pad is located below the roller.

[0009] Preferably, the driving mechanism includes a motor, which is fixed to the top of the L-shaped fixing frame, and a pulley is provided at the output end of the motor. A second pulley is fitted on the rotating sleeve, and the second pulley is connected to the first pulley via a belt.

[0010] Preferably, a rotating sleeve 2 is provided inside the liquid storage tank via a bracket. The rotating sleeve 2 is mounted on the bracket through a bearing, and the inner wall of the rotating sleeve 2 is polygonal. The drive rod passes through the rotating sleeve 2, and an mounting plate is fixed on the rotating sleeve 2. Magnetic rods are provided at both ends of the bottom of the mounting plate. A rotating mechanism for driving the magnetic rods to rotate is also provided on the bracket.

[0011] Preferably, the rotating mechanism includes an internal gear ring, which is fixed to the bottom of the bracket. Gears are provided at both ends of the top of the mounting plate, and the gears are connected to the magnetic rod. The gears are located inside the internal gear ring and mesh with the internal gear ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a conical filter disc and using a drive mechanism to rotate it, centrifugal force can quickly throw out most of the metal debris. At the same time, the roller at the top of the drive rod cooperates with the wedge plate to make the conical filter disc vibrate intermittently during rotation, which can effectively shake off irregular debris stuck on the filter screen, greatly reducing the debris residue on the filter screen, reducing the probability of filter screen clogging, significantly improving the filtration efficiency of the cutting fluid, and ensuring the smooth circulation of the cutting fluid. The drive rod and the first rotating sleeve adopt a polygonal structure to ensure that the first rotating sleeve can stably drive the drive rod to rotate, while allowing the drive rod to move up and down to achieve the vibration function. The structure is compact and reasonable. The drive mechanism is driven by a belt pulley, which ensures smooth operation and reliable power transmission. In addition, the second rotating sleeve in the liquid storage tank also adopts a polygonal structure to cooperate with the drive rod. When the drive rod rotates, it can drive the mounting plate and the magnetic rod to rotate. The meshing of the gear and the internal gear ring in the rotating mechanism allows the magnetic rod to rotate on its own axis while revolving around the revolution, which further enhances the adsorption effect of fine metal impurities in the cutting fluid and improves the purification quality of the cutting fluid.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: A milling machine cutting fluid circulation mechanism for machining ball cage retainers includes: a recovery tank 1, a liquid storage chamber 2 opened at the midpoint inside the recovery tank 1, and a slag discharge channel 3 opened in an annular shape inside the recovery tank 1. The recovery tank 1 is provided with a conical filter disc 4, and an L-shaped fixing frame 5 is fixed to the top of the recovery tank 1. A rotating sleeve 6 is provided through the L-shaped fixing frame 5 via a bearing, and a drive rod 7 is provided inside the rotating sleeve 6. The drive rod 7 passes through the midpoint of the conical filter disc 4 and is fixedly connected to it. The inner walls of the drive rod 7 and the rotating sleeve 6 are both polygonal. A top plate 8 is fixed to the top of the drive rod 7, and columns 9 are fixed to both ends of the bottom of the top plate 8. Rollers 10 are provided at the bottom of the columns 9. A wedge plate 11 is fixed to the top of the L-shaped fixing frame 5, and the wedge plate 11 is located on both sides of the rotating sleeve 6. The top of the L-shaped fixing bracket 5 is equipped with a drive mechanism 13 for rotating the rotating sleeve 6.

[0018] Furthermore, the recovery tank 1 is used to collect the cutting fluid containing metal chips generated during milling. The cutting fluid first flows into the conical filter disc 4 for preliminary filtration. The filtered cutting fluid seeps into the storage tank 2 below, while the metal chips remain on the surface of the conical filter disc 4. The rotating sleeve 6 is connected to the L-shaped fixing frame 5 via bearings, allowing for stable rotation. Its internal polygonal structure cooperates with the polygonal structure of the drive rod 7, enabling the rotating sleeve 6 to drive the drive rod 7 to rotate synchronously, while also allowing the drive rod 7 to move up and down axially. When the drive mechanism 13 drives the rotating sleeve 6 to rotate, the drive... The rod 7 drives the conical filter disc 4 to rotate, using centrifugal force to throw the metal shavings on the surface to the edge, where they fall into the slag discharge channel 3 of the recovery box 1 and are discharged. At the same time, the top plate 8 at the top of the drive rod 7 rotates with it, causing the column 9 and the roller 10 at the bottom to make circular motion. When the roller 10 contacts the wedge plate 11 on the L-shaped fixed frame 5, it moves upward along the inclined surface of the wedge plate 11, and the drive rod 7 rises accordingly. When the roller 10 disengages from the wedge plate 11, the drive rod 7 descends under the action of gravity, causing the conical filter disc 4 to vibrate, further promoting the removal of metal shavings from the filter screen.

[0019] In this embodiment: the conical filter plate 4 is located above the liquid storage tank 2, and the diameter of the conical filter plate 4 is larger than the inner diameter of the liquid storage tank 2.

[0020] Furthermore, the conical filter disc 4 is located above the liquid storage tank 2 and has a diameter larger than the inner diameter of the liquid storage tank 2. This ensures that when the metal shavings on the surface of the conical filter disc 4 are thrown to the edge under centrifugal force and vibration, they will not fall into the liquid storage tank 2, but will all enter the outer slag discharge channel 3.

[0021] In this embodiment: the top of the L-shaped fixing frame 5 is also fixed with a shock-absorbing pad 12, and the shock-absorbing pad 12 is located below the roller 10.

[0022] Furthermore, when the roller 10 disengages from the wedge plate 11 and descends with the drive rod 7, the shock-absorbing pad 12 can buffer the impact force of the roller 10, reduce vibration and noise during operation, reduce wear on parts, and extend the service life of the equipment.

[0023] In this embodiment: the drive mechanism 13 includes a motor 1301, which is fixed to the top of the L-shaped fixing frame 5. The output end of the motor 1301 is provided with a pulley 1302. A second pulley 1303 is sleeved on the rotating sleeve 6, and the second pulley 1303 is connected to the first pulley 1302 by a belt.

[0024] Furthermore, the motor 1301 drives the pulley 1302 to rotate, and the pulley 1302 transmits power to the pulley 2 1303 on the rotating sleeve 6 through the belt, so that the rotating sleeve 6 rotates synchronously with the pulley 2 1303. Then, through the polygonal cooperation between the rotating sleeve 6 and the drive rod 7, the drive rod 7 and the conical filter disc 4 are driven to rotate.

[0025] In this embodiment: a rotating sleeve 14 is installed inside the liquid storage tank 2 via a bracket. The rotating sleeve 14 is mounted on the bracket via a bearing. The inner wall of the rotating sleeve 14 is polygonal. The drive rod 7 passes through the rotating sleeve 14. An mounting plate 15 is fixed on the rotating sleeve 14. Magnetic rods 16 are provided at both ends of the bottom of the mounting plate 15. A rotating mechanism 17 for driving the magnetic rods 16 to rotate is also provided on the bracket.

[0026] Furthermore, the bracket inside the liquid storage tank 2 provides installation support for the rotating sleeve 14. The rotating sleeve 14 is connected to the bracket through a bearing. Its internal polygonal structure cooperates with the drive rod 7, so that when the drive rod 7 rotates, it can drive the rotating sleeve 14 to rotate synchronously. The rotating sleeve 14 drives the mounting plate 15 and the magnetic rod 16 at the bottom to rotate. During the rotation, the magnetic rod 16 adsorbs the fine metal shavings remaining in the cutting fluid in the liquid storage tank 2, further purifying the cutting fluid.

[0027] In this embodiment: the rotating mechanism 17 includes an internal gear ring 1701, which is fixed to the bottom of the bracket. Gears 1702 are provided at both ends of the top of the mounting plate 15, and the gears 1702 are connected to the magnetic rod 16. The gears 1702 are located inside the internal gear ring 1701 and mesh with the internal gear ring 1701.

[0028] Furthermore, the internal gear ring 1701 is fixed to the bottom of the support of the liquid storage tank 2. When the mounting plate 15 rotates with the rotating sleeve 14, the gear 1702 on the top of the mounting plate 15 rolls along the inner side of the internal gear ring 1701. Since the gear 1702 meshes with the internal gear ring 1701, the gear 1702 rotates during its revolution and drives the magnetic rod 16 connected to it to rotate synchronously, so that each area of ​​the surface of the magnetic rod 16 is in uniform contact with the cutting fluid, thereby improving the adsorption effect on fine metal impurities.

[0029] The workflow of this embodiment is as follows: The cutting fluid containing metal chips generated during the milling of the ball cage cage first flows into the recovery tank 1. The cutting fluid first contacts the conical filter plate 4 located above the storage tank 2. The liquid seeps into the storage tank 2 below through the mesh of the conical filter plate 4, while the metal chips are intercepted on the surface of the conical filter plate 4. Because the diameter of the conical filter plate 4 is larger than the inner diameter of the storage tank 2, it ensures that the chips do not fall directly into the storage tank 2. The output of the motor 1301 drives the pulley 1302 to rotate, and the power is transmitted to the pulley 1303 on the rotating sleeve 6 via a belt, causing the rotating sleeve 6 to rotate around the bearing. Both the inner wall of the rotating sleeve 6 and the drive rod 7 are polygonal structures. The rotation of the rotating sleeve 6 drives the drive rod 7 to rotate synchronously, which in turn drives the conical filter disc 4 fixed to it to rotate. Under the action of centrifugal force, the metal shavings on the surface of the conical filter disc 4 are thrown to the edge and finally fall into the slag discharge channel 3 of the annular opening in the recovery box 1, completing the initial separation. When the drive rod 7 rotates, its top plate 8 drives the columns 9 at both ends and the bottom rollers 10 to make circular motion. When the rollers 10 contact the wedge plate 11 at the top of the L-shaped fixing frame 5, they move upward along the inclined surface of the wedge plate 11, forcing the drive rod 7 to rise. When the rollers 10 disengage from the wedge plate 11, the drive rod 7 quickly descends under the action of gravity. The drop causes the conical filter disc 4 to vibrate. This intermittent vibration effectively dislodges irregular debris stuck on the conical filter disc 4, preventing it from accumulating. Combined with centrifugal force, this further improves the chip removal efficiency. Simultaneously, the shock-absorbing pad 12 at the top of the L-shaped mounting bracket 5, located below the roller 10, buffers the impact during descent, reducing noise and component wear. The cutting fluid filtered by the conical filter disc 4 enters the storage tank 2, where further removal of residual fine metal impurities is required. The support fixing rotating sleeve 14 inside the storage tank 2 has a polygonal inner wall that engages with the drive rod 7. Therefore, when the drive rod 7 rotates, it drives the rotating sleeve 14 to rotate synchronously, thereby causing the mounting bracket on the rotating sleeve 14 to... The mounting plate 15 and the magnetic rod 16 at the bottom revolve together. The gear 1702 at the top of the mounting plate 15 meshes with the internal gear ring 1701 fixed at the bottom of the bracket. When the mounting plate 15 revolves, the gear 1702 rolls along the internal gear ring 1701 and rotates, driving the magnetic rod 16 to rotate synchronously. During the revolution and rotation process, the surface of the magnetic rod 16 can uniformly adsorb fine metal impurities in the cutting fluid, greatly improving the purification accuracy of the cutting fluid. The cutting fluid purified by the storage tank 2 can be transported back to the milling machine processing area through external pumps and other equipment for cooling and lubrication again, realizing the recycling of cutting fluid, reducing production costs and reducing waste.
