Description

Technical Field

[0001] This invention relates to the field of magnetic polishing machine technology, and in particular to a polishing device for metal processing. Background Technology

[0002] In the field of surface finishing of metal parts, magnetic abrasive technology is widely used for precision polishing of complex-shaped workpieces due to its advantages such as non-contact processing, low temperature rise, and high surface quality. During magnetic abrasive processing, the stability of process parameters such as processing gap, magnetic flux density, magnetic needle filling amount, and polishing fluid ratio directly determines the surface roughness convergence efficiency and final processing quality.

[0003] However, to achieve stable application of magnetic abrasive grinding in mass production scenarios, it is necessary not only to ensure the uniformity of magnetic field distribution and the airtightness of the processing environment during the polishing stage, but also to promptly remove the grinding debris and polishing fluid and recycle the magnetic needle after polishing to avoid the residue interfering with the processing quality of the next batch of workpieces. Therefore, how to achieve efficient separation and recycling of the processing medium while ensuring polishing efficiency has become an important link for magnetic abrasive grinding technology to move towards practical production applications. In existing magnetic polishing devices, a fixed polishing container structure is often used. After the polishing operation is completed, the entire container needs to be disassembled from the machine. Then, the mixture of workpiece, magnetic needle and polishing fluid is sorted and separated by manual pouring or external auxiliary equipment. This method has a long operation process, many manual intervention steps, and it is not easy to ensure the consistency of recycling operations between different batches, which leads to a significant increase in auxiliary time and restricts the improvement of overall processing efficiency. Summary of the Invention

[0004] To address the technical problems of existing magnetic polishing devices where the state switching between polishing and separation processes relies on manual operation and involves long auxiliary working hours, and to solve the technical problems of separation components requiring frequent shutdowns for manual cleaning due to filter clogging caused by wear debris accumulation and short maintenance cycles, this invention provides a polishing device for metal processing.

[0005] The technical solutions provided by the embodiments of the present invention are as follows: The present invention provides a polishing device for metal processing, including a housing, a variable container assembly disposed at the inner top of the housing, a driving assembly disposed at the inner bottom of the housing, and a solid-liquid separation assembly disposed between the variable container assembly and the driving assembly. The variable container assembly includes a polishing barrel rotatably connected to the inside of the outer shell, a workpiece blocking net fixedly connected to the bottom of the polishing barrel, a threaded top cover threadedly connected to the top of the polishing barrel, and a lifting baffle slidably connected to the inner wall interlayer of the polishing barrel. The surface of the polishing barrel is fixedly connected with an end face toothed ring. The drive assembly includes a limiting base fixedly installed on the bottom surface of the housing, a hydraulic push rod fixedly installed on the top surface of the limiting base, a movable bracket slidably connected inside the limiting base, and a magnetic disk and a follower gear disposed inside the movable bracket. The solid-liquid separation assembly includes a collection hopper snapped into the side opening of the outer shell, an annular filter screen coaxially fixed inside the collection hopper, and a drain pipe disposed inside the collection hopper. The output end of the hydraulic jack is connected to the bottom surface of the movable bracket to adjust the height of the movable bracket. When the movable bracket is at its highest position, the drive component switches to the polishing state, and when the movable bracket is at its lowest position, the drive component switches to the disengagement state.

[0006] Furthermore, a reduction gear set is fixedly connected to the inner top of the housing. When the drive component is in a polished state, the follower gear is connected to the input end of the reduction gear set, and the output end of the reduction gear set is equipped with a Geneva mechanism.

[0007] Furthermore, a liquid storage tank is fixedly connected to the side of the outer shell, and a peristaltic pump is provided at the output end of the liquid storage tank. The output end of the groove wheel mechanism is fixedly connected to the power shaft of the peristaltic pump, which is used to drive the peristaltic pump to intermittently drip defoaming liquid into the polishing bucket.

[0008] Furthermore, when the drive component switches to the lowest separated state, the follower gear meshes with the end face gear ring set on the surface of the polishing barrel to drive the polishing barrel to rotate.

[0009] Furthermore, the outer shell is fixedly connected to an annular discharge hopper, the bottom of the outer surface of the polishing barrel is rotatably connected to the inside of the annular discharge hopper, and multiple scrapers are fixedly connected to the bottom of the outer surface of the polishing barrel in a circumferentially evenly distributed manner, the scrapers being slidably connected to the inside of the annular discharge hopper.

[0010] Furthermore, the top surface of the polishing barrel is fixedly connected to a limiting slide rod, the surface of the limiting slide rod is sleeved with a return spring, and the top surface of the lifting baffle is fixedly connected to a limiting slide frame.

[0011] Furthermore, the inner wall of the polishing barrel is provided with two sets of sliding grooves facing opposite directions. The two ends of the limiting slide are slidably connected to the inside of the two sets of sliding grooves respectively. One end of the limiting slide penetrates the inside of the polishing barrel and is slidably connected to the bottom surface of the threaded top cover.

[0012] Furthermore, the other end of the limiting slide extends through the outer wall of the polishing barrel and is slidably connected to the surface of the limiting slide rod, and the top end of the reset spring sleeved on the surface of the limiting slide rod is fixedly connected to the bottom surface of the limiting slide.

[0013] Furthermore, the movable bracket is internally fixedly connected to a motor for driving the magnetic disk to rotate, the bottom surface of the magnetic disk is fixedly connected to a drive sprocket, the surface of the drive sprocket is provided with a transmission chain, and the other end of the transmission chain is connected to the input end of the follower gear.

[0014] Furthermore, the top surface of the collecting hopper is hinged with a cover plate, and the output end of the annular discharge hopper faces the opening end of the top surface of the collecting hopper, which is used to input the target material into the interior of the annular filter screen to complete solid-liquid separation.

[0015] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: 1. Through the coordinated setup of the solid-liquid separation component, the annular discharge hopper, and the workpiece blocking net, the solid-liquid mixture ejected by the centrifugal rotation of the polishing barrel in the separated state is introduced into the solid-liquid separation component through the annular discharge hopper. The liquid passes through the filter screen and is discharged through the drain pipe. The magnetic needle is trapped inside the filter screen, and the workpiece is blocked inside the polishing barrel. This achieves the separation of the workpiece, the magnetic needle, and the polishing liquid, simplifies the separation operation of the workpiece and the magnetic needle, improves the material recovery efficiency, and enhances the process switching efficiency.

[0016] 2. With the movable bracket, the follower gear moves up and down synchronously with the movable bracket. When in the polishing state, the follower gear meshes with the reduction gear set. After being converted to intermittent rotation by the Geneva mechanism, it drives the peristaltic pump to add defoaming liquid to the polishing tank in a metered manner. When switching to the separation state, the follower gear disengages from the reduction gear set and instead meshes with the end face gear ring on the surface of the polishing tank, driving the polishing tank to rotate and perform centrifugal separation. By raising and lowering the movable bracket, the same follower gear can drive different actuators in different states. There is no need to configure independent drive sources and clutch devices for liquid supply and separation, which effectively reduces the number of parts and assembly complexity of the whole machine.

[0017] 3. Through the setting of the annular filter screen, the magnetic disk continuously rotates during the separation operation to generate an alternating magnetic field. This magnetic field passes through the collection hopper and acts on the magnetic needles accumulated inside the annular filter screen, causing the magnetic needles to keep tumbling inside the filter screen. The mechanical vibration accelerates the liquid to pass through the filter screen while disturbing the solid phase deposition layer, preventing the filter screen pores from being blocked by the accumulation of magnetic needles. The magnetic needle tumbling drive does not require additional vibrators or cleaning devices. The original magnetic disk rotation can be used to simultaneously complete the dual functions of solid-liquid separation and filter screen anti-clogging. Attached Figure Description

However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0022] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0023] like Figures 1 to 10As shown, an embodiment of the present invention provides a polishing device for metal processing, including a housing 1, a variable container assembly 2 disposed on the inner top of the housing 1, a drive assembly 3 disposed on the inner bottom of the housing 1, a solid-liquid separation assembly 4 disposed between the variable container assembly 2 and the drive assembly 3, a liquid storage tank 5 fixedly connected to the side of the housing 1, a peristaltic pump 6 disposed at the output end of the liquid storage tank 5, and a reduction gear set 8 fixedly connected to the inner top of the housing 1. When the drive assembly 3 is in the polishing state, the follower gear 35 is drivenly connected to the input end of the reduction gear set 8, and a grooved wheel mechanism 9 is assembled at the output end of the reduction gear set 8. The output end of the grooved wheel mechanism 9 is fixedly connected to the power shaft of the peristaltic pump 6, for driving the peristaltic pump 6 to intermittently drip defoaming liquid into the polishing bucket 21. The variable container assembly 2 includes a polishing barrel 21 rotatably connected to the inside of the outer shell 1, a workpiece blocking net 22 fixedly connected to the bottom of the polishing barrel 21, a threaded top cover 23 threadedly connected to the top of the polishing barrel 21, and a lifting baffle 25 slidably connected to the inner wall interlayer of the polishing barrel 21. The surface of the polishing barrel 21 is fixedly connected with an end face toothed ring. The drive assembly 3 includes a limiting base 31 fixedly installed on the bottom surface of the housing 1, a hydraulic push rod 32 fixedly installed on the top surface of the limiting base 31, a movable bracket 33 slidably connected inside the limiting base 31, a magnetic disk 34 and a follower gear 35 disposed inside the movable bracket 33. A motor for driving the magnetic disk 34 to rotate is fixedly connected inside the movable bracket 33. A drive sprocket is fixedly connected to the bottom surface of the magnetic disk 34. A transmission chain 36 is disposed on the surface of the drive sprocket. The other end of the transmission chain 36 is connected to the input end of the follower gear 35. The output end of the hydraulic push rod 32 is connected to the bottom surface of the movable bracket 33 for adjusting the height of the movable bracket 33. When the movable bracket 33 is at its highest position, the drive assembly 3 switches to the polishing state. When the movable bracket 33 is at its lowest position, the drive assembly 3 switches to the disengaged state.

[0024] In specific implementation, the annular discharge hopper 7 is fixedly installed inside the outer shell 1. The rotation limit of the polishing barrel 21 is achieved by the cooperation between the annular discharge hopper 7 and the outer shell 1. Bearings are respectively provided at the contact ends of the annular discharge hopper 7 and the outer shell 1 with the polishing barrel 21 to achieve smooth rotation of the polishing barrel 21 relative to the outer shell 1 and the annular discharge hopper 7. A clamping arm that cooperates with the movable support 33 is provided on the back of the annular discharge hopper 7 to further constrain the movement trajectory of the movable support 33. The limiting base 31 and the movable support 33 are connected by the sliding cooperation of the sliding rod and the sliding sleeve to limit and guide the lifting and lowering trajectory of the movable support 33. When the hydraulic push rod 32 is in the fully extended state, the movable support 33 is raised to the highest position. At this time, the magnetic disk 34 is close to the bottom surface of the polishing barrel 21, but a certain gap is reserved between the two. The magnetic disk 34 can attract the magnetic needles inside the polishing barrel 21, and the equipment switches to the polishing state.

[0025] When the equipment is in the polishing state, the movable bracket 33 is at its highest position. The follower gear 35 and the input end of the reduction gear set 8 form a transmission connection through gear meshing. The reduction gear set 8 reduces the power output by the follower gear 35 and transmits it to the Geneva mechanism 9. The Geneva mechanism 9 converts the continuous rotational motion into intermittent rotational motion and outputs it to the power shaft of the peristaltic pump 6 to realize the intermittent drive of the peristaltic pump 6. The input end of the peristaltic pump 6 extends to the bottom of the reservoir 5, and is used to draw the defoaming liquid inside the reservoir 5 and intermittently drip it into the polishing tank 21. By intermittently supplying liquid, the defoaming liquid is added quantitatively only during the period when foam is generated, so as to avoid excessive use of defoaming liquid and dilution of the polishing liquid concentration. Meanwhile, when the equipment is in the polishing state, the solid-liquid separation component 4 is not installed inside the housing 1, and the movable bracket 33 is at its highest position. At this time, the follower gear 35 and the reduction gear set 8 maintain a transmission connection.

[0026] When the hydraulic push rod 32 is in the fully retracted state, the movable support 33 is pulled down to the lowest position. At this time, the magnetic disk 34 is away from the bottom surface of the polishing barrel 21, and the equipment switches to the separation state. The movable support 33 descends to the bottom, and the working surface of the magnetic disk 34 is away from the bottom surface of the polishing barrel 21. The follower gear 35 descends synchronously with the movable support 33, disengages from the transmission connection with the reduction gear set 8, and instead forms a meshing transmission with the end face gear ring fixedly connected to the surface of the polishing barrel 21 to drive the polishing barrel 21 to rotate. The centrifugal force is used to throw out the polishing liquid and debris in the polishing barrel 21. Meanwhile, the side opening of the outer casing 1 is unobstructed, and the solid-liquid separation component 4 is installed inside the outer casing 1 through the side opening to receive the material discharged from the polishing barrel 21 and perform solid-liquid separation.

[0027] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, an annular discharge hopper 7 is fixedly connected inside the outer shell 1, and the bottom of the outer surface of the polishing barrel 21 is rotatably connected to the inside of the annular discharge hopper 7. Multiple scrapers are fixedly connected to the bottom of the outer surface of the polishing barrel 21 in a circumferentially evenly distributed manner. The scrapers are slidably connected inside the annular discharge hopper 7. When the drive assembly 3 switches to the lowest separated state, the follower gear 35 meshes with the end face gear ring set on the surface of the polishing barrel 21 to drive the polishing barrel 21 to rotate. A limiting slide rod 24 is fixedly connected to the top surface of the polishing barrel 21, and a return spring is sleeved on the surface of the limiting slide rod 24. A limiting slide 26 is fixedly connected to the top surface of the lifting baffle 25. The inner wall of the polishing barrel 21 has two sets of sliding grooves facing opposite directions. The two ends of the limiting slide 26 are slidably connected to the inside of the two sets of sliding grooves respectively. One end of the limiting slide 26 penetrates the inside of the polishing barrel 21 and is slidably connected to the bottom surface of the threaded top cover 23. The other end of the limiting slide 26 penetrates the outer wall of the polishing barrel 21 and is slidably connected to the surface of the limiting slide rod 24. The top end of the reset spring sleeved on the surface of the limiting slide rod 24 is fixedly connected to the bottom surface of the limiting slide 26.

[0028] In specific implementation, during the switching of the working state of the drive component 3, the height of the lifting baffle 25 is controlled by the threaded top cover 23, the limiting slide rod 24 and the reset spring sleeved on the surface of the limiting slide rod 24, so that the polishing barrel 21 can adapt to different working states. The limiting slide rod 24 and the limiting slide 26 are slidably engaged. The return spring sleeved on the surface of the limiting slide rod 24 always applies an upward elastic force to the limiting slide 26, so that the lifting baffle 25 is at the highest end of the inner wall interlayer of the polishing barrel 21 when there is no external force. At this time, the workpiece blocking net 22 is connected to the internal cavity of the polishing barrel 21, and the mesh size of the workpiece blocking net 22 is smaller than the outer diameter of the target workpiece, so as to ensure that liquid and debris can pass smoothly in the separated state, while the workpiece is blocked inside the polishing barrel 21. The polishing barrel 21 is threadedly connected to the threaded top cover 23. When the threaded top cover 23 is screwed into the polishing barrel 21, one end of the limiting slide 26 extends into the polishing barrel 21 and abuts against the bottom surface of the threaded top cover 23. As the threaded top cover 23 continues to screw in, the limiting slide 26 and the lifting baffle 25 are pressed down to the bottom of the inner wall interlayer of the polishing barrel 21, blocking the communication between the workpiece blocking net 22 and the inner cavity of the polishing barrel 21, so that the polishing barrel 21 enters a closed polishing state. A sealing gasket is provided at the contact part between the lifting baffle 25 and the bottom surface of the polishing barrel 21 to ensure the sealing performance in the closed state.

[0029] like Figure 10 As shown, in this embodiment, the solid-liquid separation component 4 includes a collection hopper 41 snapped into the side opening of the outer casing 1, an annular filter screen 42 coaxially fixed inside the collection hopper 41, a drain pipe 43 disposed inside the collection hopper 41, a cover plate 44 hinged to the top surface of the collection hopper 41, and the output end of the annular discharge hopper 7 facing the top opening end of the collection hopper 41, for inputting the target material into the interior of the annular filter screen 42 to complete solid-liquid separation.

[0030] In specific implementation, the side opening of the outer shell 1 is set between the variable container assembly 2 and the drive assembly 3. The overall height of the collection hopper 41 is adapted to the height of the side opening. When the collection hopper 41 is inserted into the side opening of the outer shell 1, the cover plate 44 covers the top surface of the collection hopper 41 and the annular filter screen 42. Under the squeezing action of the baffle reserved inside the outer shell 1, the overall sealing state of the solid-liquid separation assembly 4 is guaranteed. The bottom surface of the annular filter screen 42 is higher than the inner bottom surface of the collection hopper 41. The two are connected by a frustum-shaped guide plate. The drain pipe 43 is located at the bottom of the collection hopper 41 and is connected to the inside of the collection hopper 41. Its output end extends toward the outside of the outer shell 1. In a sealed state, the collecting hopper 41 is connected to the output end of the annular discharge hopper 7 through the pre-reserved opening on its top surface, so that the target material discharged from the annular discharge hopper 7 is directly input into the interior of the annular filter screen 42. The liquid filtered by the annular filter screen 42 is collected at the bottom of the collecting hopper 41 and discharged from the equipment through the drain pipe 43, thereby achieving efficient solid-liquid separation.

[0031] Working principle: like Figures 1 to 10 As shown, the threaded top cover 23 is screwed into the interior of the polishing barrel 21. The threaded top cover 23 applies downward pressure to the limiting slide 26, further pressing the lifting baffle 25 down to the bottom of the inner wall interlayer of the polishing barrel 21, so that the lifting baffle 25 is in close contact with the bottom surface of the polishing barrel 21, blocking the communication between the workpiece blocking net 22 and the internal cavity of the polishing barrel 21. Then, the target workpiece, magnetic needle and polishing liquid are put into the interior of the polishing barrel 21 through the top opening of the threaded top cover 23, thus completing the preparation work before the polishing operation.

[0032] After preparation, the motor inside the movable bracket 33 is started to drive the magnetic disk 34 to rotate. When the magnetic disk 34 rotates, it generates an alternating magnetic field, which drives the magnetic needle inside the polishing barrel 21 to make disordered rolling motion in the polishing liquid. The magnetic needle produces micro-cutting with the surface of the workpiece, thereby realizing the preset polishing operation. While the magnetic disk 34 rotates, the transmission chain 36 set on its surface drives the follower gear 35 to rotate synchronously. After the follower gear 35 is reduced by the reduction gear set 8, the power is transmitted to the Geneva mechanism 9. The Geneva mechanism 9 converts the continuous rotational motion of the follower gear 35 into intermittent rotational motion, thereby driving the peristaltic pump 6 to operate intermittently, so that the peristaltic pump 6 can intermittently pump the defoaming liquid inside the liquid storage tank 5 into the polishing barrel 21. By using an intermittent liquid supply method, the defoaming liquid is added in a fixed amount only during the period when foam is generated, avoiding the dilution of the polishing liquid concentration due to excessive use of defoaming liquid. This effectively eliminates the foam generated during polishing operations and reduces the adverse effects of foam on the polishing process.

[0033] After the polishing operation is completed, the hydraulic push rod 32 retracts, causing the movable support 33 and its top magnetic disk 34 and follower gear 35 to fall to the bottom along the guide direction of the limiting base 31. At this time, the magnetic disk 34 is away from the bottom surface of the polishing barrel 21, and the magnetic driving effect of the magnetic disk 34 on the magnetic needles inside the polishing barrel 21 is greatly reduced. At the same time, the follower gear 35 descends synchronously with the movable support 33, disengaging from the transmission connection with the reduction gear set 8, and instead forming a meshing transmission with the end face gear ring fixedly connected to the surface of the polishing barrel 21.

[0034] Cover the top surface of the collection hopper 41 with the cover plate 44 to complete the sealing of the collection hopper 41 and the annular filter screen 42. Then insert the solid-liquid separation component 4 into the side opening of the outer shell 1. At this time, the opening reserved on the top surface of the collection hopper 41 is connected to the output end of the annular discharge hopper 7. At the same time, the physical isolation of the solid-liquid separation component 4 reduces the magnetic influence of the magnetic disk 34 on the variable container component 2. Subsequently, the threaded top cover 23 is unscrewed from the inside of the polishing barrel 21 and removed. The reset spring sleeved on the surface of the limiting slide rod 24 lifts the limiting slide 26 and the lifting baffle 25 to the highest position under the action of elastic restoring force. At this time, the workpiece blocking net 22 is reconnected with the internal cavity of the polishing barrel 21. The liquid inside the polishing barrel 21 flows into the interior of the annular discharge hopper 7 through the mesh of the workpiece blocking net 22 under the action of gravity, and then enters the interior of the annular filter net 42 through the output end of the annular discharge hopper 7. At this time, the drive assembly 3 is restarted, and the magnetic disk 34 and the follower gear 35 rotate again. The follower gear 35 meshes with the end face gear ring on the surface of the polishing barrel 21, driving the polishing barrel 21 to rotate at a different speed. When the polishing barrel 21 rotates, it generates centrifugal force. Larger workpieces are blocked inside the polishing barrel 21 by the workpiece blocking net 22, while smaller magnetic needles and residual liquid are thrown off under the action of centrifugal force, passing through the mesh of the workpiece blocking net 22 and entering the interior of the annular discharge hopper 7, thus achieving the initial separation of the workpiece and the magnetic needle. During the variable speed rotation of the polishing barrel 21, the scraper fixedly connected to the bottom of its outer surface rotates synchronously with the polishing barrel 21, continuously scraping the solid-liquid mixture accumulated inside the annular discharge hopper 7 to the output end of the annular discharge hopper 7, and then guiding it to the middle position of the annular filter screen 42. After the liquid passes outward through the annular filter screen 42, it collects at the bottom of the collection hopper 41, and then is transported to the external collection device through the drain pipe 43. The magnetic needle is blocked by the annular filter screen 42. In this way, the separation of the workpiece from the magnetic needle and the separation of the magnetic needle from the polishing liquid are completed simultaneously during the separation operation, so that the workpiece can be quickly removed. At the same time, the magnetic needle is collected inside the annular filter screen 42, which can be quickly restored to the standby state for the next polishing operation. After the separation operation is completed and the polished workpiece is removed, the solid-liquid separation component 4 is taken out from the side opening of the outer shell 1, and the hydraulic push rod 32 is controlled to raise the movable support 33 to the highest position, so that the equipment can quickly return to the polishing state and enter the next polishing cycle operation.
