Description

Technical Field

[0001] The invention relates to the technical field of metal polishing, in particular to a surface treatment device for an electromagnetic brake housing. Background Art

[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 the existing dry grinding and polishing, the brake housing and abrasive are usually poured into a drum together for rotational 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 brake housing surface. For electromagnetic brake housings with high precision requirements, surface damage will affect subsequent use.

[0003] At the same time, during the process of grinding the brake housing with the abrasive, metal debris will fall off the surface of the brake housing, and these metal debris will be mixed in the abrasive and come into contact with the brake housing. Since the hardness of the metal debris is often close to or higher than the workpiece itself, when the two come into contact with each other, the irregular structure of the metal debris will form scratches on the surface of the brake housing, causing the appearance of the brake housing to not meet the production quality. Moreover, after continuous use, the abrasive itself will be worn out, that is, the rough surface of the abrasive will gradually become smooth or the abrasive particle size will become smaller, and thus it will be unable to act on the grinding of the brake housing. If the abrasive is poured out directly as a whole, workers will need to screen the abrasive, which will increase the workload of the workers, and the screened abrasive will need to be poured back into the drum by the workers again, adding production steps.

The diameter is smaller than the diameter of the limiting rod 4; each limiting rod 4 is provided with a number of limiting groups distributed in a straight line and at equal intervals; each limiting group is composed of a number of blocking rods 4001 distributed in a circular shape and at equal intervals; the blocking rod 4001 is slidingly connected to the limiting rod 4, and a spring is fixed between the blocking rod 4001 and the inner circular surface of the limiting rod 4; each limiting rod 4 is provided with a number of bearing parts 4002, and the diameter of the bearing part 4002 is smaller than the diameter of the limiting rod 4, and the bearing part 4002 is located between two adjacent limiting groups; a filtering interception component is provided in the rotating drum 2.

[0020] The filtering interception assembly includes a screen 5, a baffle 103 and a rotating plate 106; a plurality of screens 5 are connected to the drum 2, and the sieve holes of the screens 5 are smaller than the abrasive particle size; a plurality of baffles 103 are detachably connected to the drum 2; each baffle 103 is detachably connected to the adjacent screen 5; a storage cavity 10302 is formed between each baffle 103 and the inner wall of the drum 2; a plurality of through slots are provided on each baffle 103, and two oppositely arranged rotating plates 106 are rotatably connected to each through slot; each rotating plate 106 is made of metal, and the overall weight of each rotating plate 106 is large; a plurality of blocking parts 10301 are provided on each baffle 103; each rotating plate 106 can only be rotated and opened toward the inner wall of the drum 2 under the restriction of the adjacent blocking parts 10301.

[0021] Spring pieces 104 are also included; each chuck 101 is fixedly connected with a plurality of spring pieces 104 .

[0022] Furthermore, each chuck 101 is provided with a plurality of protrusions 10101 corresponding to the number and position of the chuck slots on the tray 102 .

[0023] Furthermore, each limit rod 4 is connected to both ends with a snap ring 4003; the diameter of each snap ring 4003 is larger than the width of the slot of the tray 102; each chuck 101 is provided with a number of extensions 10102 corresponding to the number and position of the slots on the tray 102.

[0024] Furthermore, each supporting portion 4002 is configured to be in the shape of a circular tube with a small diameter in the middle and large diameters on both sides.

[0025] When grinding and polishing the surface of the brake housing, the operator first opens the cover 2001, then loads the brake housing to be processed and an appropriate amount of abrasive into the inside of the drum 2 in sequence, and then closes the cover 2001, and drives the drum 2 to rotate by starting the servo motor 3 configured on the fixed frame 1, causing the brake housing and the abrasive inside the drum 2 to roll continuously. During this process, the abrasive and the surface of the brake housing are continuously rubbed against each other, realizing all-round grinding and polishing of the brake housing surface. Subsequently, it is only necessary to open the cover 2001 to remove the polished brake housing from the abrasive, or control the servo motor 3 to drive the drum 2 to rotate so that the cover 2001 is facing downward. After that, after opening the cover 2001, the abrasive and the brake housing are poured out of the drum 2 together. Subsequently, it is only necessary to use screening equipment to separate the brake housing and the abrasive, and finally pour the abrasive back into the drum 2.

[0026] When the brake housings are ground and polished in batches, the brake housings are not fixed, which leads to collisions between the brake housings during the polishing process, causing the brake housings to be damaged or scratched. At the same time, considering that it is cumbersome and laborious for workers to find the brake housings in the abrasives when taking out the materials after the existing grinding, and when the cover plate 2001 is turned downward to pour out the brake housings and the abrasives together, the abrasives need to be re-screened and poured back into the drum 2, which also increases the production steps. Therefore, before the brake housing is loaded into the drum 2, the worker holds the brake housing and inserts its bearing end into the limit rod 4. The brake housing is specifically located on the bearing portion 4002 of the limit rod 4. During the installation process, the worker first presses the baffle rod 4001, and the spring between the baffle rod 4001 and the limit rod 4 is compressed to avoid the brake housing. After a single brake housing is installed in place, the worker stops pressing the baffle rod 4001. At this time, the baffle rod 4001 rebounds and resets under the action of the spring, thereby utilizing the baffle rod 4001 to limit the movable space of the brake housing, so that the brake housing cannot cross the baffle rod 4001 during the subsequent grinding and polishing process, thereby avoiding the brake housing from colliding with each other during the grinding process.

[0027] After the brake housings are placed on the several bearing parts 4002 on the limit rod 4, the worker inserts the two ends of the limit rod 4 into the corresponding slots on the two pallets 102 in turn. During the process of the limit rod 4 being inserted into the pallets 102 in turn, the worker moves the previously placed limit rod 4 to make the limit rod 4 drive the two pallets 102 to rotate, so that the remaining slots of the pallets 102 without the limit rod 4 are rotated to face upward for placing the next limit rod 4. In order to ensure the stability of the pre-placed limit rod 4 and prevent it from falling during the rotation of the pallet 102, a rubber half ring 105 is provided on the slot of the pallet 102. The inner diameter of the rubber half ring 105 is smaller than the diameter of the limit rod 4. When the two ends of the limit rod 4 are inserted into the slot of the pallet 102, the rubber half ring 105 is squeezed, and the limit rod 4 is fixed by the rubber half ring 105 to prevent the pre-placed limit rod 4 from falling into the rotating drum 2 during the rotation of the pallet 102.

[0028] After all the limit rods 4 are placed in place, the cover 2001 is closed first, and then the worker pushes the two chucks 101 toward the tray 102 respectively. When the protrusion 10101 of the chuck 101 coincides with the slot of the tray 102, the protrusion 10101 of the chuck 101 locks the tray 102 to prevent the tray 102 from rotating during the subsequent grinding and polishing process. At the same time, the protrusion 10101 of the chuck 101 also blocks the limit rod 4, so that the limit rod 4 cannot escape from the slot of the tray 102, ensuring the stability of the limit rod 4 during the grinding and polishing process; then the servo motor is started. The machine 3 drives the drum 2 to rotate. It should be noted that: since the centrifugal force generated by the rotation of the drum 2 is not enough to make the abrasive perform a circular motion, the abrasive always accumulates in the bottom area of ​​the inner wall of the drum 2 under the dominance of gravity, presenting a compound motion state of periodic collapse and tumbling. At the same time, since the diameter of each bearing part 4002 is smaller than the inner diameter of the brake housing, and the bearing part 4002 is set to a circular tube with a small diameter in the middle and large diameters on both sides, when the drum 2 starts to rotate, the brake housing will perform irregular motion 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, the abrasive will enter the gap between the inner diameter of the brake housing and the bearing part 4002 based on the designed gap between the inner diameter of the brake housing and the bearing part 4002. At the same time, when the bearing part 4002 drives the brake housing into the abrasive, due to the movement resistance of the abrasive and the structural characteristics of the bearing part 4002, the brake housing will produce multi-directional irregular swings during the movement. At the same time, the rotation of the drum 2 prompts the abrasive to form a non-directional tumbling motion state under the combined action of gravity and centrifugal force. This irregular tumbling motion caused by the brake housing The composite motion mode composed of the swing and the disordered motion of the abrasive can make the abrasive act on the surface of the brake housing in a random multi-angle contact manner, thereby realizing comprehensive coverage grinding of the blind corner area of ​​the brake housing structure; after the grinding is completed, it is only necessary to open the cover 2001, reset the chuck 101, and then remove the limit rod 4 in turn to complete the material removal work of the brake housing, and the abrasive will remain in the drum 2. There is no need to rely on workers to find the brake housing in the abrasive, and there is no need to pour out the brake housing and the abrasive together for screening, and then pour the abrasive back into the drum 2, thereby improving the material removal efficiency.

[0029] Furthermore, through the provision of the spring sheet 104, when the worker pushes the chuck 101 close to the tray 102, the spring sheet 104 is squeezed by the side wall of the drum 2 and embedded in the drum 2. The spring sheet 104 will come into contact with the side wall of the drum 2 and be continuously squeezed, thereby forcing the elastic material to deform and completely embed into the assembly gap between the drum 2 and the chuck 101. At this time, the spring sheet 104 fits tightly to the contact interface between the drum 2 and the chuck 101 by virtue of its elastic restoring force. This adjustable elastic deformation characteristic is used to effectively improve the fixed stability of the chuck 101 in the axial position of the drum 2.

[0030] Furthermore, when the two ends of the limiting rod 4 are embedded in the opposite grooves on the two trays 102, the clamping rings 4003 provided at the two ends of the limiting rod 4 will be as shown in FIG. Figure 4 As shown in the state of contact with the side of the tray 102, since the diameter of the retaining ring 4003 is larger than the width of the retaining groove of the tray 102, when the protrusion 10101 coincides with the tray 102, the retaining ring 4003 will be subjected to the radial clamping action of the extension portion 10102 of the chuck 101 and the tray 102 at the same time, further enhancing the fixing effect of the limit rod 4 and ensuring the stability of the limit rod 4 during the grinding and polishing process.

[0031] It is also taken into consideration that when the abrasive in the drum 2 continuously grinds the brake housing, the abrasive itself will be consumed, making it gradually lose its grinding function. At the same time, during the grinding process, the detached metal debris mixed in the abrasive may cause scratches on the surface of the brake housing. Therefore, when the abrasive is continuously turned over in the drum 2, since the mesh of the screen 5 is 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 detached from the brake housing during grinding will also pass through the screen 5, thereby screening out invalid abrasive and metal debris during the grinding process. Compared with the traditional method of pouring the brake housing and the abrasive out of the drum 2 together, the step of re-adding the abrasive is eliminated, and there is no need for workers to screen the abrasive, thereby improving the adaptability of the equipment and reducing the risk of detached metal debris mixed in the abrasive causing scratches on the surface of the brake housing.

[0032] It is further considered that if the screened abrasives and metal debris are directly discharged, an additional blocking structure will be needed to prevent the abrasives and metal debris from being thrown towards the workers under the action of centrifugation, and to prevent debris from splashing in the factory. At the same time, since finer debris powder, namely abrasive powder and metal debris powder, will be produced during the grinding process, additional suction equipment will be needed to process the powder if it is discharged, which not only increases the production cost but also increases the overall footprint of the equipment. Therefore, the abrasives and metal debris that pass through the screen 5 will first be stored between the screen 5 and the drum 2, while the effective abrasives that still have processing capacity will continue to participate in the grinding and polishing work under the interception of the screen 5. However, during the grinding and polishing process, when the over-worn abrasives and metal debris are driven to the upper half area by the rotating drum 2, the abrasives and metal debris will pass through the screen 5 due to the influence of gravity, and then fall down into the abrasive with grinding function. Therefore, by providing the baffle frame 103 and the rotating plate 106, when the baffle frame 103 and the rotating plate 106 are both in the lower half area of ​​the rotating drum 2, the rotating plate 106 will rotate open due to its own gravity, causing the over-worn abrasives and metal debris to enter the storage chamber 10302. As the over-worn abrasives and metal debris rotate to the upper half area with the rotating drum 2, the rotating plate 106 also comes to the upper half area. Under the influence of gravity, the rotating plate 106 is as follows Figure 6As shown in the closed state, the rotating plate 106 cannot be opened toward the screen 5 due to the restriction of the blocking part 10301, so that the over-worn abrasives and metal debris cannot pass through the rotating plate 106 and are intercepted in the storage chamber 10302, thereby ensuring that the over-worn abrasives 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 half of the rotating drum 2, since the rotating plate 106 is made of metal and the overall weight of a single rotating plate 106 is large, during the rotation of the rotating drum 2, the gravity of the rotating plate 106 itself will overcome the centrifugal force generated when the rotating drum 2 rotates, so that the rotation change of the rotating plate 106 is small. At the same time, the abrasives and metal debris in the storage chamber 10302 are also affected by the centrifugal force and are not easily accumulated on the rotating plate 106, resulting in most of the abrasives and metal debris being accumulated in the storage chamber 10302.

[0033] It should be noted that after the surface of the brake housing is polished, the operator opens the cover 2001 and moves the screen 5 and the baffle 103 on one side of the cover 2001 as shown in FIG. Figure 3 As shown in the figure, after all the limit rods 4 are placed in place, the screen 5 and the baffle 103 that were previously pulled out are first inserted back, and then the cover 2001 is closed.

[0034] After the grinding is completed, the operator first controls the servo motor 3 to drive the drum 2 to rotate until the cover plate 2001 is facing upward, and then the worker pulls out the baffle 103 and the screen 5 at the highest position from the drum 2, and then cleans the abrasive and metal debris supported on the baffle 103, and then reinserts the cleaned baffle 103 and screen 5 assembly into the drum 2, and then controls the rotation of the drum 2 through the precise indexing of the servo motor 3, so that the worker cleans the remaining baffles 103 and screen 5 in turn; the purpose of pulling out the screen 5 for cleaning is to prevent the sieve holes on the screen 5 from being damaged. When the baffle 103 is pulled out for cleaning, the worker can observe whether there are large particles of abrasive in the abrasive on the baffle 103. When large particles of abrasive are found, it can be determined that the sieve holes of the screen 5 corresponding to the baffle 103 may be damaged or deformed. This detection method integrated into the conventional cleaning process does not require additional disassembly of the screen 5 for separate inspection, eliminating the difficulty of workers holding the small screen 5 for visual comparison. When large particles of abrasive are found, only the screen 5 needs to be disassembled and replaced, avoiding the large particles of abrasive being screened out along with the failed abrasive during the subsequent grinding and polishing process.

[0035] Example 2: Based on Example 1, Figures 8-10As shown, it also includes a slide bar 201, a dial 202, a hose 204, an air pipe 205 and a corrugated cover 206; a slide bar 201 is fixedly connected to the rotating drum 2; the slide bar 201 passes through the 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 set on the slide bar 201; an annular air supply cover 10201 is rotatably connected to each tray 102; Each tray 102 is provided with a number of connecting ports 10202 distributed equidistantly in a circular shape, and each connecting port 10202 passes through the adjacent tray 102; all connecting ports 10202 on the same tray 102 are connected to the adjacent annular air supply hood 10201; the annular air supply hood 10201 on the right is connected to a number of hoses 204, and the annular air supply hood 10201 on the left is connected to a number of air pipes 205; all hoses 204 and all air pipes 205 pass through the drum 2 and are connected to an external pump.

[0036] A protective cover 203 is also included; a protective cover 203 is fixedly connected 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, and the corrugated cover 206 is wrapped by the dial 202 and the protective cover 203.

[0037] It also includes a movable rod 207; a movable rod 207 is fixedly connected between the two clamping rings 4003 on each limiting rod 4, and the clamping ring 4003 is rotatably connected to the limiting rod 4; each movable rod 207 is provided with a plurality of extrusion portions 20701 distributed equidistantly in a ring shape.

[0038] Furthermore, the dial 202 is provided with a plurality of tiny air holes, and each air hole is provided with a one-way membrane that is opened only toward the middle of the drum 2 ; each air hole on the dial 202 is communicated with the interior of the bellows 206 .

[0039] In this embodiment, by setting the initial state of the blocking rod 4001 to: the outer side surface of the blocking rod 4001 coincides with the outer ring surface of the limiting rod 4, the spring between the limiting rod 4 and the blocking rod 4001 is in a non-pressurized state, thereby facilitating the worker to sequentially insert the brake housing on the bearing portion 4002 of the limiting rod 4, without the need for the worker to repeatedly press the blocking rod 4001 to avoid the brake housing, thereby improving the convenience of installing the brake housing; after the brake housing is fully inserted on the limiting rod 4, the worker holds the retaining ring 4003 and rotates it, thereby driving the movable rod 207 and the extrusion portion 20701 to rotate synchronously, so that the extrusion portion 20701 is as shown Figure 10 As shown, each bearing portion 4002 is pushed up, so that all the blocking rods 4001 are pushed out of the limiting rod 4 at the same time, and the spring between the limiting rod 4 and the blocking rod 4001 is compressed to limit the brake housing on the limiting rod 4.

[0040] After the polishing operation is completed, since there is a groove structure for the installation of the coil on the brake housing, the groove will naturally retain some abrasives during the processing. When the worker takes the limit rod 4 out of the drum 2, the abrasives accumulated in the groove will be taken out of the drum 2 together, which not only causes the loss of abrasives, but also forces the worker to collect and backfill the abrasives, which significantly increases the workload of the worker. Therefore, when the polishing is completed, the external pump is started to supply gas to the hose 204. The gas enters the corrugated cover 206 through the hose 204 and the connecting port 10202 to expand it, thereby pushing the dial 202 to move to the left along the surface of the slide rod 201. When the edge of the dial 202 contacts the brake housing, the brake The brake housing produces a tilted displacement under the action of force. At this time, the abrasive accumulated in the groove of the brake housing naturally slides down into the rotating 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 it is tilted. Then the pump is switched to the suction mode, and the gas in the bellows 206 is extracted through the hose 204 to shrink it, thereby resetting the dial 202. During the resetting process, it contacts the brake housing again to form a secondary dumping action. After multiple reciprocating motions, 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 processing of the abrasive. This mechanism effectively solves the problem of the abrasive being brought out with the workpiece in the traditional process.

[0041] During the polishing operation, the dust generated in the drum 2 will cause health hazards and visual interference to the workers when the cover 2001 is opened. Therefore, after completing the polishing operation, before the worker opens the cover 2001, the air pump on the air pipe 205 is controlled to start pumping air, so that the suction force acts on the drum 2 through the air pipe 205 and the connecting port 10202, thereby extracting the dust generated in the drum 2, and avoiding the dust from causing health hazards and visual interference to the workers; further, the air pipe 205 and the dial 202 push the brake housing synchronously, and by opening an air hole on the dial 202, when the hose 204 blows air into the corrugated cover 206, the air pressure in the corrugated cover 206 continues to increase. At this time, the one-way membrane on the dial 202 is opened under the influence of the air pressure. Since the air hole on the dial 202 is connected to the corrugated cover 206, and since the air hole is small Without affecting the expansion of the bellows 206, the gas can also be sprayed into the drum 2 from the air holes, and then when the dial 202 moves to the left, the air flow blown out from the air holes of the dial 202 forces the dust away from the air pipe 205 to move to the left, thereby improving the efficiency of the air pipe 205 in sucking dust. When the hose 204 starts to pump air, that is, the dial 202 moves to the right, the one-way membrane on the dial 202 is in a closed state, causing the bellows 206 to shrink and reset 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 are restricted by the chuck 101 and cannot rotate, and the annular air supply hood 10201 cannot rotate with the tray 102, thereby avoiding the situation where the hose 204 and the air pipe 205 are entangled with the tray 102.

[0042] Furthermore, during the polishing process, the protective cover 203 cooperates with the dial 202 to completely wrap the bellows 206, effectively isolating the contact between the abrasive and the bellows 206, and preventing the sealing failure caused by abrasive wear.

The scope of the following claims is to be accorded the broadest interpretation so as to encompass all modifications and equivalent structures and functions.
