Description

Technical Field

[0001] This invention relates to the field of metal polishing technology, and more particularly to a surface treatment device for an electromagnetic brake housing. Background Technology

[0002] In the production process of electromagnetic brake housings, surface grinding and polishing is a key process to ensure their performance and appearance quality. In existing dry grinding and polishing methods, the brake housing and abrasive are usually poured into a drum together for rotating grinding. When a large number of brake housings are processed, the brake housings will collide with each other in the drum, causing damage to the surface of the brake housings. For electromagnetic brake housings with high precision requirements, surface damage will affect subsequent use.

[0003] Meanwhile, during the grinding process of the brake housing, metal fragments will fall off the surface of the brake housing. These metal fragments will be mixed with the abrasive and come into contact with the brake housing. Since the hardness of the metal fragments is often close to or higher than that of the workpiece itself, when the two come into contact, the irregular structure of the metal fragments will form scratches on the surface of the brake housing, resulting in the appearance of the brake housing not meeting the production quality. Moreover, after continuous use, the abrasive itself will be worn down, that is, the rough surface of the abrasive will gradually become smooth or the abrasive particle size will become smaller, and thus it will not be able to perform grinding on the brake housing. If the abrasive is poured out directly as a whole, workers need to sieve the abrasive, which will increase the workload of workers. Furthermore, the sieved abrasive must be poured back into the drum by workers, adding production steps. Summary of the Invention

Detailed Implementation

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: As Figures 1-7 As shown, a surface treatment device for an electromagnetic brake housing includes a fixed frame 1, a rotating drum 2, and a servo motor 3; the rotating drum 2 is rotatably connected to the fixed frame 1; a cover plate 2001 is connected to the rotating drum 2; the servo motor 3 is connected to the fixed frame 1, and the output end of the servo motor 3 is connected to the rotating drum 2.

[0032] It also includes a limit rod 4, a chuck 101, a tray 102, a rubber semi-ring 105, and a filter interception assembly; a chuck 101 is slidably connected to both the left and right sides of the rotating drum 2; two opposing trays 102 are rotatably connected inside the rotating drum 2, and each tray 102 has several equally spaced grooves arranged in a ring; the opposing grooves on the two trays 102 are connected to a limit rod 4, which is hollow; a rubber semi-ring 105 is fixedly connected to the groove of each tray 102, and the inner part of the rubber semi-ring 105 is... The diameter is smaller than that of the limiting rod 4; each limiting rod 4 has several limiting groups distributed in a straight line at equal intervals; each limiting group consists of several stop rods 4001 distributed in a ring at equal intervals; the stop rods 4001 are slidably connected to the limiting rod 4, and a spring is fixed between the stop rods 4001 and the inner circular surface of the limiting rod 4; each limiting rod 4 is provided with several bearing parts 4002, and the diameter of the bearing parts 4002 is smaller than that of the limiting rod 4, and the bearing parts 4002 are located between two adjacent limiting groups; a filter interception assembly is provided inside the rotating drum 2.

[0033] The filtering and interception assembly includes a screen 5, a baffle frame 103, and a rotating plate 106. Several screens 5 are connected inside the rotating cylinder 2, and the mesh size of the screens 5 is smaller than the abrasive particle size. Several baffle frames 103 are detachably connected inside the rotating cylinder 2. Each baffle frame 103 is detachably connected to an adjacent screen 5. A storage cavity 10302 is formed between each baffle frame 103 and the inner wall of the rotating cylinder 2. Several through slots are provided on each baffle frame 103, and two opposing rotating plates 106 are rotatably connected to each through slot. Each rotating plate 106 is made of metal and has a large overall weight. Several blocking parts 10301 are provided on each baffle frame 103. Each rotating plate 106 rotates and opens only towards the inner wall of the rotating cylinder 2 under the restriction of adjacent blocking parts 10301.

[0034] It also includes spring plates 104; several spring plates 104 are fixedly connected to each chuck 101.

[0035] Furthermore, each chuck 101 is provided with several protrusions 10101 corresponding to the number and position of the slots on the tray 102.

[0036] Furthermore, each limiting rod 4 has a retaining ring 4003 connected to both ends; the diameter of each retaining ring 4003 is greater than the width of the slot on the tray 102; each chuck 101 has several extensions 10102 corresponding to the number and position of slots on the tray 102.

[0037] Furthermore, each bearing part 4002 is configured as a circular tube with a small diameter in the middle and a large diameter on both sides.

[0038] When polishing the surface of the brake housing, the operator first opens the cover plate 2001, then loads the brake housing to be processed and an appropriate amount of abrasive into the rotating drum 2. The cover plate 2001 is then closed, and the rotating drum 2 is driven to rotate by the servo motor 3 mounted on the fixed frame 1. This causes the brake housing and abrasive inside the rotating drum 2 to tumble continuously. During this process, the abrasive and the surface of the brake housing experience continuous friction, achieving all-around polishing of the brake housing surface. Afterwards, simply open the cover plate 2001 to remove the polished brake housing from the abrasive, or control the servo motor 3 to rotate the rotating drum 2 so that the cover plate 2001 faces downwards. After opening the cover plate 2001, the abrasive and brake housing are poured out of the rotating drum 2 together. Subsequently, a screening device is used to separate the brake housing and abrasive, and finally, the abrasive is poured back into the rotating drum 2.

[0039] During batch grinding and polishing of brake housings, the lack of fixation caused collisions between the housings, resulting in dents or scratches. Furthermore, considering the tedious and laborious process of workers searching for brake housings in the abrasive after grinding, and the need to re-sieve and return the abrasive to the rotating drum 2 when emptying the brake housings and abrasive together with the cover plate 2001 facing down, which adds to the production steps, a new method is used: before loading the brake housings into the rotating drum 2, workers hold the brake housings and thread their bearing ends onto the limiting rod 4. Furthermore, the brake housing is specifically located on the bearing part 4002 of the limiting rod 4. During the installation process, the worker first presses the stop rod 4001, and the spring between the stop rod 4001 and the limiting rod 4 is compressed to avoid the brake housing. After a single brake housing is installed in place, the worker stops pressing the stop rod 4001. At this time, the stop rod 4001 rebounds and resets under the action of the spring, thereby using the stop rod 4001 to restrict the movement space of the brake housing, so that the brake housing cannot cross the stop rod 4001 during the subsequent grinding and polishing process, thus avoiding the situation where the brake housings collide with each other during the grinding process.

[0040] After brake housings are placed on several bearing portions 4002 on the limiting rod 4, the workers sequentially insert the two ends of the limiting rod 4 into the corresponding slots on the two trays 102. During the process of inserting the limiting rod 4 into the trays 102, the workers move the previously placed limiting rod 4 to rotate the two trays 102, causing the remaining slots on the trays 102 without limiting rods 4 to rotate upwards to place the next limiting rod 4. To ensure the stability of the previously placed limiting rod 4 and prevent it from falling off during the rotation of the trays 102, rubber semi-rings 105 are set on the slots of the trays 102. The inner diameter of the rubber semi-rings 105 is smaller than the diameter of the limiting rod 4. When the two ends of the limiting rod 4 are inserted into the slots of the trays 102, the rubber semi-rings 105 are squeezed, and the limiting rod 4 is fixed by the rubber semi-rings 105 to prevent the previously placed limiting rod 4 from falling into the rotating drum 2 during the rotation of the trays 102.

[0041] After all the limit rods 4 are in place, the cover plate 2001 is closed first. Then, the worker pushes the two chucks 101 towards the tray 102. When the protrusion 10101 of the chuck 101 aligns with the slot of the tray 102, the protrusion 10101 of the chuck 101 locks the tray 102, preventing the tray 102 from rotating during subsequent grinding and polishing. At the same time, the protrusion 10101 of the chuck 101 also blocks the limit rods 4, preventing them from disengaging from the slots of the tray 102, thus ensuring the stability of the limit rods 4 during grinding and polishing. Then, the servo motor is activated. Machine 3 drives the rotating drum 2 to rotate. It should be noted that because the centrifugal force generated by the rotation of drum 2 is insufficient to cause the abrasive to undergo circular motion, the abrasive, under the dominant force of gravity, always accumulates in the bottom area of ​​the inner wall of drum 2, exhibiting a combined motion of periodic collapse and tumbling. Simultaneously, because the diameter of each bearing part 4002 is smaller than the inner diameter of the brake housing, and the bearing part 4002 is designed as a circular tube with a smaller diameter in the middle and larger diameters on both sides, when drum 2 begins to rotate, the brake housing will undergo irregular movement within the constraint range of the bearing part 4002 under the action of centrifugal force. When the bearing part 4002 drives... When the brake housing moves to the abrasive accumulation area, based on the designed gap between the inner diameter of the brake housing and the support part 4002, the abrasive will enter the gap between the inner diameter of the brake housing and the support part 4002. Simultaneously, when the support part 4002 pulls the brake housing into the abrasive, due to the movement resistance of the abrasive and the structural characteristics of the support part 4002, the brake housing will experience multi-directional irregular oscillation during movement. At the same time, the rotational motion of the rotating drum 2 causes the abrasive to form a non-directional tumbling motion under the combined action of gravity and centrifugal force. This irregular oscillation caused by the brake housing... The combined motion mode of oscillation and disordered movement of the abrasive enables the abrasive to act on the surface of the brake housing in a random, multi-angle contact manner, thereby achieving comprehensive grinding of the dead-angle areas of the brake housing structure. After grinding, simply open the cover plate 2001, reset the chuck 101, and then remove the limit rods 4 in sequence to complete the material removal of the brake housing. The abrasive will remain in the rotating drum 2, eliminating the need for workers to search for the brake housing in the abrasive, and eliminating the need to pour the brake housing and abrasive out together for screening and then pour the abrasive back into the rotating drum 2, thus improving material removal efficiency.

[0042] Furthermore, with the spring plate 104, when the worker pushes the chuck 101 close to the tray 102, the spring plate 104 is pressed into the rotating cylinder 2 by the side wall of the rotating cylinder 2. The spring plate 104 will come into contact with the side wall of the rotating cylinder 2 and be subjected to continuous compression, thereby forcing the elastic material to deform and completely embed into the assembly gap between the rotating cylinder 2 and the chuck 101. At this time, the spring plate 104 is tightly attached to the contact interface between the rotating cylinder 2 and the chuck 101 by its elastic restoring force. This adjustable elastic deformation characteristic effectively improves the fixing stability of the chuck 101 in the axial position of the rotating cylinder 2.

[0043] Furthermore, when the two ends of the limiting rod 4 are inserted into the corresponding slots on the two trays 102, the retaining rings 4003 provided at both ends of the limiting rod 4 will be in the following position: Figure 4 As shown, the circlip 4003 is in contact with the side of the tray 102. Since the diameter of the circlip 4003 is larger than the width of the slot of the tray 102, when the protrusion 10101 overlaps with the tray 102, the circlip 4003 will be simultaneously subjected to the radial clamping action of the extension 10102 of the chuck 101 and the tray 102, which further enhances the fixing effect on the limit rod 4 and ensures the stability of the limit rod 4 during the grinding and polishing process.

[0044] Furthermore, considering that as the abrasive in the rotating drum 2 continuously grinds the brake housing, the abrasive itself will wear down, gradually losing its grinding function. At the same time, during the grinding process, metal debris mixed in with the abrasive can cause scratches on the surface of the brake housing. Therefore, as the abrasive continuously tumbles in the rotating drum 2, because the sieve holes of the screen 5 are smaller than the particle size of the abrasive, the overall particle size of the excessively worn abrasive will become smaller and will pass through the screen 5 during the rolling process. At the same time, the metal debris that falls off the brake housing during grinding will also pass through the screen 5, thus removing ineffective abrasive and metal debris during the grinding process. Compared with the traditional method of pouring the brake housing and abrasive out of the rotating drum 2 together, this eliminates the step of adding abrasive again and eliminates the need for workers to sieve the abrasive, improving the adaptability of the equipment and reducing the risk of scratches on the surface of the brake housing caused by metal debris mixed in with the abrasive.

[0045] Furthermore, considering that directly discharging the screened abrasive and metal shavings would require additional blocking structures to prevent them from being flung at workers by centrifugal force and to prevent splattering within the factory, and also because the grinding process generates fine powder, namely abrasive powder and metal shavings powder, external discharge would require additional suction equipment to handle the powder, increasing both production costs and the overall footprint of the equipment, abrasive and metal shavings passing through screen 5 are first stored between screen 5 and the rotating drum 2, while the remaining usable abrasive continues to participate in the grinding and polishing process under the interception of screen 5. However, during the grinding and polishing process, when the excessively worn abrasive and metal debris are carried to the upper region by the rotating drum 2, the abrasive and metal debris will pass through the screen 5 due to gravity and fall downwards into the abrasive with grinding function. Therefore, by setting the baffle 103 and the rotating plate 106, when both the baffle 103 and the rotating plate 106 are in the lower region of the rotating drum 2, the rotating plate 106 will rotate and open due to its own gravity, causing the excessively worn abrasive and metal debris to enter the storage cavity 10302. As the excessively worn abrasive and metal debris follow the rotating drum 2 to the upper region, the rotating plate 106 also moves to the upper region. Under the influence of gravity, the rotating plate 106 is shaped like... Figure 6In the closed state shown, the rotating plate 106 cannot open towards the screen 5 due to the restriction of the blocking part 10301. This prevents excessively worn abrasive and metal debris from passing through the rotating plate 106 and intercepts them in the storage cavity 10302. This ensures that excessively worn abrasive and metal debris will not pass through the screen 5 again and fall down into the abrasive with grinding function. It should be noted that when the rotating plate 106 is in the upper part of the rotating cylinder 2, because the rotating plate 106 is made of metal and the overall weight of a single rotating plate 106 is large, the weight of the rotating plate 106 itself will overcome the centrifugal force generated when the rotating cylinder 2 rotates. This results in a small change in the rotation of the rotating plate 106. At the same time, the abrasive and metal debris in the storage cavity 10302 are also affected by the centrifugal force and are not easy to accumulate on the rotating plate 106. As a result, most of the abrasive and metal debris will be accumulated in the storage cavity 10302.

[0046] It should be noted that after the operator opens the cover 2001 to polish the surface of the brake housing, the screen 5 and the baffle 103 located on one side of the cover 2001 should be placed as follows: Figure 3 As shown, after all the limit rods 4 are in place, first insert back the previously pulled-out screen 5 and baffle 103, and then close the cover plate 2001.

[0047] After grinding, the operator first controls the servo motor 3 to drive the drum 2 to rotate until the cover plate 2001 is facing upwards. Then, the worker pulls out the highest-positioned baffle 103 and screen 5 from the drum 2, cleans the abrasive and metal shavings supported on the baffle 103, and then reinserts the cleaned baffle 103 and screen 5 assembly into the drum 2. Subsequently, the servo motor 3 precisely controls the rotation of the drum 2, allowing the worker to clean the remaining baffles 103 and screens 5 in sequence. The purpose of cleaning the screen 5 is to prevent the screen holes on the screen 5 from being damaged. When cleaning the baffle 103, workers can observe whether there are large abrasive particles in the abrasive on the baffle 103. When large abrasive particles are found, it can be determined that the sieve holes of the corresponding sieve 5 of the baffle 103 may be damaged or deformed. This detection method, which is integrated into the routine cleaning process, does not require the additional disassembly of the sieve 5 for separate inspection. It eliminates the difficulty of operation when workers hold a small sieve 5 for visual comparison. When large abrasive particles are found, only the sieve 5 needs to be disassembled and replaced. This avoids the large abrasive particles being screened out along with the failed abrasive during the subsequent grinding and polishing process.

[0048] Example 2: Based on Example 1, as follows Figures 8-10As shown, it also includes a slide bar 201, a dial 202, a hose 204, an air tube 205, and a corrugated cover 206; a slide bar 201 is fixedly connected inside the rotating cylinder 2; the slide bar 201 passes through two trays 102, and the trays 102 are rotatably connected to the slide bar 201; a corrugated cover 206 is fixedly connected to the tray 102 on the right side; a dial 202 is fixedly connected to the side of the corrugated cover 206 away from the tray 102, and the dial 202 is slidably mounted on the slide bar 201; an annular air supply cover 10201 is rotatably connected to each tray 102; Each tray 102 has several equidistant, annularly distributed connecting ports 10202, and each connecting port 10202 penetrates the adjacent tray 102; all connecting ports 10202 on the same tray 102 are connected to the adjacent annular air supply hood 10201; several hoses 204 are connected to the annular air supply hood 10201 on the right side, and several air pipes 205 are connected to the annular air supply hood 10201 on the left side; all hoses 204 and all air pipes 205 penetrate the rotating drum 2 and are connected to the external pump.

[0049] It also includes a protective cover 203; a protective cover 203 is fixedly attached to the tray 102 on the right side, and the side of the protective cover 203 away from the tray 102 contacts the dial 202. The corrugated cover 206 is wrapped by the dial 202 and the protective cover 203.

[0050] It also includes a movable rod 207; each of the two retaining rings 4003 on each limiting rod 4 is fixedly connected to a movable rod 207, and the retaining rings 4003 are rotatably connected to the limiting rod 4; each movable rod 207 is provided with several extrusion parts 20701 that are distributed in a ring at equal intervals.

[0051] Furthermore, the dial 202 has several small air holes, and each air hole is provided with a one-way membrane that opens only towards the center of the rotating drum 2; each air hole on the dial 202 is connected to the inside of the corrugated cover 206.

[0052] In this embodiment, the initial state of the stop rod 4001 is set such that its outer surface coincides with the outer ring surface of the limiting rod 4, and the spring between the limiting rod 4 and the stop rod 4001 is uncompressed. This facilitates the worker to sequentially thread the brake housing onto the bearing portion 4002 of the limiting rod 4, eliminating the need for the worker to repeatedly press the stop rod 4001 to avoid the brake housing, thus improving the ease of brake housing installation. After the brake housing is fully threaded onto the limiting rod 4, the worker holds the retaining ring 4003 and rotates it, thereby driving the movable rod 207 and the pressing portion 20701 to rotate synchronously, causing the pressing portion 20701 to be in the shape of... Figure 10 The springs between the limit rods 4 and the stop rods 4001 are compressed, thus restricting the brake housing on the limit rods 4.

[0053] After polishing, the brake housing has grooves for coil installation. These grooves naturally retain some abrasive material during processing. When the worker removes the limit rod 4 from the rotating drum 2, this accumulated abrasive material is carried out of the drum 2, causing abrasive loss and forcing the worker to perform additional collection and refilling work, significantly increasing workload. Therefore, after polishing, an external pump is started to supply gas to the hose 204. The gas enters the bellows 206 through the hose 204 and the connecting port 10202, causing it to expand and push the dial 202 to move to the left along the surface of the slide bar 201. When the edge of the dial 202 contacts the brake housing, the brake... Under the action of force, the brake housing tilts and displaces. At this time, the abrasive accumulated in the groove of the brake housing naturally slides into the rotary drum 2 due to gravity. During this process, the curved design of the bearing part 4002 ensures that the brake housing will not get stuck when tilted. Then, the pump switches to the suction mode and draws the gas out of the bellows 206 through the hose 204, causing it to contract and thus reset the dial 202. During the reset process, it contacts the brake housing again to form a secondary tilting action. After multiple reciprocating movements, the residual abrasive in the groove of the brake housing is completely removed. At this time, the worker can directly remove the brake housing without additional abrasive handling. This mechanism effectively solves the problem of abrasive being carried out with the workpiece in traditional processes.

[0054] During the polishing process, the dust generated inside the rotating drum 2 can cause health hazards and visual disturbances to workers when the cover plate 2001 is opened. Therefore, before the workers open the cover plate 2001 after the polishing operation is completed, the air pump on the air pipe 205 is controlled to start suction, so that the suction force acts on the rotating drum 2 through the air pipe 205 and the connecting port 10202, thereby removing the dust generated inside the rotating drum 2 and avoiding health hazards and visual disturbances to workers caused by the dust. Furthermore, the dust suction by the air pipe 205 and the push of the brake housing by the dial 202 are carried out simultaneously. By opening air holes on the dial 202, when the hose 204 blows air into the corrugated cover 206, the air pressure inside the corrugated cover 206 continuously increases. At this time, the one-way diaphragm on the dial 202 opens under the influence of air pressure. Since the air holes on the dial 202 are connected to the corrugated cover 206, and since the air holes are small, Without affecting the expansion of the corrugated cover 206, gas can also be sprayed into the rotating drum 2 from the air hole. When the dial 202 moves to the left, the airflow blown out from the air hole of the dial 202 forces the dust far away from the air pipe 205 to move to the left, improving the dust suction efficiency of the air pipe 205. When the hose 204 starts to suck air, that is, when the dial 202 moves to the right, the one-way membrane on the dial 202 is in the closed state, so that the corrugated cover 206 contracts and resets under the action of negative pressure. It should be noted that when the limit rod 4 is installed, the tray 102 is in a rotatable state. As the tray 102 rotates, the hose 204 and the air pipe 205 cannot rotate due to the restriction of the chuck 101, and thus the annular air supply cover 10201 cannot rotate with the tray 102, thus avoiding the situation where the hose 204 and the air pipe 205 are tangled with the tray 102.

[0055] Furthermore, during the polishing process, the protective cover 203 and the dial 202 work together to completely enclose the corrugated cover 206, effectively isolating the abrasive from contact with the corrugated cover 206 and preventing sealing failure caused by abrasive wear.

[0056] Although the invention has been described with reference to exemplary embodiments, it should be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the following claims should be given the broadest interpretation so as to cover all variations and equivalent structures and functions.
