Description

Technical Field

[0001] The invention belongs to the technical field of spring washer processing, and particularly relates to a multi-directional deburring device for spring washer production and a preparation process thereof. Background Art

[0002] The multi-directional deburring device for spring washer production is a device specially used to remove burrs generated during the processing of spring washers to improve their surface quality and performance. The application of this device is crucial to the production of spring washers. It can not only improve the appearance quality of spring washers and make their surface smooth and flat to meet the needs of some high-precision assembly scenarios, but also prevent the washers from being worn during use due to residual burrs, scratching other parts, and affecting assembly accuracy. Problems such as these, thereby improving the reliability and stability of the entire product, are widely used in various spring washer manufacturing companies, covering many industries such as automobiles, machinery manufacturing, aerospace, etc., and are one of the key equipment to ensure the quality and performance of spring washers.

[0003] The existing multi-directional deburring device and its preparation process for spring washer production have the following disadvantages when used:

[0004] 1. Most traditional spring washer deburring devices use simple drum rotation or single grinding methods. The movement path of the spring washer in the device is relatively fixed, which may cause some areas to be fully in contact with the grinding medium, while some areas are not in contact, resulting in incomplete and uneven burr removal.

[0005] 2. When some deburring devices in the prior art are used in a more violent grinding or striking manner, the internal components of the device are easily loosened, deformed or even damaged due to the excessive impact force, resulting in increased maintenance costs and shortened service life of the equipment. Summary of the invention

[0006] The purpose of the present invention is to provide a multi-directional deburring device and a preparation process for the existing spring washer production, which has the advantage of realizing multi-directional deburring of spring washers, avoiding the problems of incomplete and uneven burr grinding and poor device stability during use of spring washers, improving product quality and production efficiency, and reducing equipment maintenance costs and operating noise.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: a multi-directional deburring device for spring washer production, comprising an outer roller and a driving frame, the outer roller is arranged on the top of the driving frame, the inner wall of the outer roller is provided with an inner roller, the surface of the inner roller is bolted with a sliding frame, the inner wall of the outer roller is bolted with a flexible connection structure, the surface of the flexible connection structure is slidably connected to the inner wall of the sliding frame, the inner wall of the inner roller is bolted with a guide striking assembly, the inner wall of the inner roller is provided with a rotating shaft, the surface of the rotating shaft is bolted with a mounting block, and the top and bottom of the mounting block are bolted with a striking mixing structure.

[0008] The above technical scheme is adopted, by setting an outer drum, a driving frame, an inner drum, a sliding frame, a flexible connection structure, a guide striking assembly, a rotating shaft, a mounting block and a striking mixed structure. First, the combination of the outer drum and the driving frame provides a basic framework for the entire deburring device. The driving frame, as a power support component, can ensure that the outer drum performs stable rotational motion at a predetermined speed and direction. The outer drum not only protects the internal components, but its inner wall also provides a limited space for the operation of the inner drum, so that the inner drum can maintain a stable trajectory during rotation to avoid deviation or shaking, thereby ensuring the movement stability of the spring washer during the deburring process and reducing the problem of inconsistent deburring effect caused by irregular movement. The inner drum cooperates with the flexible connection structure of the outer drum through the sliding frame on the surface. The sliding connection method of the sliding frame and the flexible connection structure enables the inner drum to have a certain degree of relative independence and flexibility while rotating with the outer drum. When the inner drum is subjected to the force of the internal striking mixed structure, it can produce an oscillating motion relative to the outer drum within a certain range. This oscillating motion has an all-round deburring effect on the spring washer. The effect has a lifting effect, so that the spring washer is no longer simply rolling in the inner drum, but can rub and collide with the grinding medium in multiple dimensions, ensuring that all surfaces of the washer, including the inner and outer circumferential surfaces, upper and lower planes, and edge corners, can be fully deburred, improving the thoroughness and uniformity of deburring. The guide striking component on the inner wall of the inner drum and the striking hybrid structure on the rotating shaft cooperate with each other to form an efficient deburring power structure. The guide striking component can not only guide the movement path of the spring washer in the inner drum, but also ensure the striking When the block is hit by the striking mixing structure, the impact force can be accurately transmitted to the spring washer, so that the washer is continuously impacted and vibrated during the movement, further enhancing the separation effect of the burr and the washer body. The striking mixing structure rotates driven by the rotating shaft, so that the striking mixing structure can produce multi-angle and multi-force striking actions during the rotation process, continuously and forcefully stirring and striking the spring washer, prompting the washer to be fully mixed with the grinding medium and produce strong friction, thereby quickly and effectively removing burrs and improving the efficiency and quality of deburring.

[0009] The present invention is further configured as follows: the inner drum includes a rotating frame, a filter screen and a reinforcement block, the surface of the reinforcement block is bolted to the inner wall of the rotating frame, the surface of the filter screen is bolted to the inner wall of the rotating frame, the inner wall of the filter screen is bolted to the surface of the reinforcement block, and the inner wall of the sliding frame is bolted to the surface of the rotating frame.

[0010] By adopting the above technical scheme, by arranging a rotating frame, a filter screen and a reinforcement block, the rotating frame in the inner drum provides a main support frame for the entire inner drum structure, ensuring the integrity and stability of the inner drum, enabling it to withstand the weight of the internal spring washers and other components as well as various forces generated during operation. The filter screen can prevent the spring washers from accidentally falling out of the pores of the inner drum during the deburring process, ensuring the safety and stability of the processing process, while also facilitating the subsequent centralized cleaning of these debris and keeping the inside of the outer drum clean. The reinforcement block further enhances the structural strength of the rotating frame, especially when subjected to the impact force of hitting the mixing structure and the friction force of the spring washers, it can effectively prevent the deformation or damage of the rotating frame.

[0011] The present invention is further configured as follows: the guided striking assembly includes a striking block and a spiral guide plate, the side of the reinforcing block close to the spiral guide plate is bolted to the spiral guide plate, the inner wall of the striking block is bolted to the surface of the spiral guide plate, and the surface of the spiral guide plate is bolted to the inner wall of the filter.

[0012] The above technical solution is adopted by setting a striking block and a spiral guide plate. The spiral guide plate, through its unique spiral shape, provides a guiding method for the spring washer to move in an orderly manner along a specific path. This allows the spring washer to pass through each key grinding area in turn while rotating with the inner drum, avoiding the situation where some areas are over-grinded and other areas are under-grinded, thereby improving the uniformity and comprehensiveness of deburring. Moreover, when the striking mixed structure hits the striking block, the striking block transmits the impact force to the spiral guide plate, and then to the spring washer, causing the washer to receive additional impact and vibration during the movement. This impact vibration can effectively destroy the bonding force between the burr and the washer body, further promote the shedding of the burr, enhance the deburring effect, and enable some more stubborn burrs to be completely removed, thereby improving the surface quality and performance of the product.

[0013] The present invention is further configured as follows: the flexible connection structure includes a fixed ring, a buffer assembly, a movable frame and a slider, the slider is bolted to the movable frame on one side close to the movable frame, the surface of the slider is slidably connected to the inner wall of the sliding frame, the inner wall of the movable frame is movably connected to the surface of the sliding frame, the buffer assembly is bolted to the movable frame on one side close to the movable frame, the buffer assembly is bolted to the fixed ring on one side close to the inner wall of the fixed ring, and the surface of the fixed ring is bolted to the inner wall of the outer drum.

[0014] By adopting the above technical scheme, a fixed ring, a buffer assembly, a movable frame and a slider are set. The fixed ring in the flexible connection structure serves as a basic component connected to the inner wall of the outer drum, and plays a role in fixing and supporting the entire flexible connection structure, ensuring the stability of the flexible connection structure during operation. The combination of the movable frame and the slider enables the inner drum and the outer drum to maintain a certain connection relationship while having relative freedom of movement. The buffer assembly can effectively absorb and buffer the impact force generated during the vibration of the inner drum, prevent these impact forces from being directly transmitted to the outer drum, and avoid deformation, loosening or damage of the outer drum due to excessive impact, thereby ensuring the stability and reliability of the entire device.

[0015] The present invention is further configured as follows: the buffer assembly includes a connecting block, a damping structure and a fixed block, the fixed block is bolted to the movable frame on one side close to the movable frame, the damping structure is bolted to the fixed block on one side close to the fixed block, the connecting block is bolted to the damping structure on one side close to the damping structure, and the connecting block is bolted to the fixed ring on one side close to the inner wall of the fixed ring.

[0016] By adopting the above technical solution, by setting up a connecting block, a damping structure and a fixed block, the impact force of the inner roller is transmitted to the damping structure, thereby effectively reducing the peak value of the impact force and avoiding damage to the outer roller. The connecting block connects the damping structure with the fixed ring, ensuring the continuity and stability of the buffering process, so that the entire buffering assembly can function efficiently.

[0017] The present invention is further configured as follows: the left and right sides of the outer drum are both bolted to a limiting frame, an output assembly is arranged on the right side of the limiting frame, the surface of the rotating shaft is rotatably connected to the inner wall of the limiting frame, and the left side of the output assembly is bolted to the right side of the rotating shaft.

[0018] By adopting the above technical solution, by setting a limit frame and an output assembly, the limit frames on both sides of the outer drum support and position the rotating shaft, ensuring that the rotating shaft always maintains a stable axial position during rotation, avoiding the normal operation of the striking mixing structure due to the deviation or shaking of the rotating shaft, thereby ensuring the stability and reliability of the deburring process. The output assembly is connected to the rotating shaft and can output and transmit the rotational power of the rotating shaft.

[0019] The present invention is further configured as follows: the striking mixing structure includes a rotating sleeve assembly, a striking part, a torsion spring and a connecting plate, the connecting plate is bolted to the mounting block on one side close to the mounting block, the left side of the torsion spring is fixedly connected to the inner wall of the connecting plate, the right side of the torsion spring is fixedly connected to the left side of the striking part, the surface of the striking part is rotatably connected to the inner wall of the connecting plate, and the inner wall of the rotating sleeve assembly is rotatably connected to the surface of the striking part.

[0020] The above technical scheme is adopted, by setting a rotating sleeve assembly, a striking part, a torsion spring and a connecting plate, and the connecting plate in the striking mixing structure is used as an installation basis to firmly connect the entire structure with the mounting block, thereby ensuring that the striking mixing structure can rotate stably under the drive of the rotating shaft. The setting of the torsion spring provides elastic potential energy for the striking part, so that the striking part can generate elastic striking action during the rotation process. This elastic striking not only increases the diversity and randomness of the striking force, but also enables the striking part to rebound quickly after contacting the guide striking assembly to prepare for the next strike, thereby improving the striking frequency and efficiency. The cooperation between the striking part and the rotating sleeve assembly further enhances the striking effect. The rotating sleeve assembly can rotate relatively during the rotation of the striking part, so that the striking mixing structure can generate multi-angle and multi-force striking actions during rotation, and the spring washer is more fully and strongly stirred and struck, so that the washer and the grinding medium are fully mixed and strongly rubbed, thereby quickly and effectively removing burrs, improving the efficiency and quality of deburring, and meeting the needs of efficient production.

[0021] The present invention is further configured as follows: the rotating sleeve assembly includes a rotating cylinder and a protruding block, the protruding block is bolted to the rotating cylinder on one side close to the rotating cylinder, and the inner wall of the rotating cylinder is rotatably connected to the surface of the striking part.

[0022] By adopting the above technical solution, a rotating cylinder and a protruding block are set, and the rotating cylinder in the rotating sleeve assembly provides an installation basis for the protruding block, and at the same time, the rotating cylinder itself can rotate on the surface of the striking part. This rotation characteristic increases the relative movement between the rotating sleeve assembly and the striking part, further enriching the form and effect of the striking action. The protruding block can generate more complex friction and impact force changes through its protruding shape during the interaction with the striking part, so that the striking part is subjected to more directions and forces of different sizes when rotating, so that the striking hybrid structure can implement more diversified and high-intensity striking on the spring washer as a whole, further improving the efficiency and effect of deburring.

[0023] The present invention is further configured as follows: the striking part includes a striking frame, a rotating block and a rotating plate, the right side of the rotating plate is bolted to the left side of the rotating block, the left side of the rotating plate is fixedly connected to the right side of the torsion spring, the side of the striking frame close to the rotating block is bolted to the rotating block, and the inner wall of the rotating cylinder is rotatably connected to the surface of the striking frame.

[0024] The above technical scheme is adopted, by setting a striking frame, a rotating block and a rotating plate, the striking frame in the striking part is the part that directly contacts and acts with the spring washer and the guide striking assembly, and its sturdy structure can withstand the impact force generated during high-speed rotation and frequent striking, thereby ensuring the effectiveness and reliability of the striking action. The rotating block is connected to the striking frame, which plays the role of connecting and transmitting rotational force, so that the striking frame can generate stable rotational motion with the rotation of the rotating shaft, thereby realizing continuous striking of the spring washer. The connection between the rotating plate and the torsion spring provides the striking frame with elastic striking ability, so that it can produce elastic deformation and rebound when in contact with other components, thereby increasing the flexibility and diversity of the striking action, further enhancing the deburring effect on the spring washer, and enabling the burrs to fall off from the washer surface more thoroughly, thereby improving the surface quality and performance of the spring washer.

[0025] A preparation process of a multi-directional deburring device for producing spring washers, comprising the following steps:

[0026] S1. First, pour the spring washer material that needs to be deburred into the inner drum through the opening on the inner drum. At this time, suitable grinding media, such as sand, ceramic beads, etc., are placed on the inner wall of the outer drum in advance. These grinding media will fully contact with the spring washer during the subsequent rotation of the inner and outer drums to remove burrs. The guide striking assembly arranged on the inner wall of the inner drum, including the striking block and the spiral guide plate, can guide the movement path of the material in the drum so that each part of the washer can get sufficient grinding opportunities. After preparation, start the driving frame to drive the outer drum to start the drum grinding and deburring operation;

[0027] S2. When the driving frame drives the outer roller to start rotating, since the outer roller and the inner roller are connected by a flexible connection structure, the rotation of the outer roller will be transmitted to the inner roller through the flexible connection structure, causing the inner roller to rotate accordingly. In this process, the rotating shaft in the inner roller also starts to rotate, thereby driving the striking mixing structure to rotate. The rotating striking mixing structure will continuously strike the surface of the guide striking component. Due to the action of the striking force, the inner roller will produce an oscillation effect on the inner wall of the outer roller. This oscillation causes the spring washer to continuously change its position and posture during the deburring process of friction with the grinding medium, ensuring that burrs in all directions can be effectively ground. At the same time, the flexible connection structure can effectively absorb and buffer the impact force generated by the vibration of the inner roller, ensuring that the normal rolling of the outer roller is not affected, and maintaining the stable operation of the entire deburring device.

[0028] In summary, the present invention has the following beneficial effects:

[0029] 1. By setting the inner drum, first, pour the spring washer material into the inner drum through the opening of the inner drum, and at the same time place suitable grinding media such as sand, ceramic beads, etc. on the inner wall of the outer drum, so that it can fully contact with the washer in the subsequent rotation to remove burrs. The guide striking assembly on the inner wall of the inner drum can effectively guide the movement trajectory of the material in the drum to ensure that all parts of the washer can be fully polished. The outer drum and the drive frame constitute the basic structure of the device. The drive frame as a power support can ensure that the outer drum rotates stably at a predetermined speed and direction. The inner wall of the outer drum provides a limited space for the inner drum to run, so that its trajectory is stable, avoiding deviation and shaking, ensuring the stability of the washer movement, and reducing the difference in deburring effect caused by irregular movement. After preparation, start the drive frame to drive the outer drum to start the drum grinding and deburring operation;

[0030] 2. By setting up a striking mixing structure, when the driving frame drives the outer drum to rotate, with the help of the flexible connection structure, the rotation of the outer drum is transmitted to the inner drum, causing it to rotate accordingly. At this time, the rotating shaft in the inner drum drives the striking mixing structure to rotate, and the rotating striking mixing structure continuously strikes the surface of the guide striking component. The striking force generated makes the inner drum vibrate on the inner wall of the outer drum. This vibration allows the spring washer to continuously change its position and posture during the friction deburring process with the grinding medium, thereby achieving effective grinding of burrs in all directions and ensuring the thoroughness and uniformity of deburring. At the same time, the flexible connection structure can effectively absorb and buffer the impact force generated by the vibration of the inner drum, prevent it from interfering with the normal rolling of the outer drum, and maintain the stable operation of the entire deburring device.

DETAILED DESCRIPTION

[0042] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0043] Embodiment 1:

[0044] refer to Figure 1-10A multi-directional deburring device for producing spring washers comprises an outer drum 1 and a driving frame 6, wherein the outer drum 1 is arranged on the top of the driving frame 6, an inner drum 2 is arranged on the inner wall of the outer drum 1, a sliding frame 7 is bolted to the surface of the inner drum 2, a flexible connection structure 4 is bolted to the inner wall of the outer drum 1, the surface of the flexible connection structure 4 is slidably connected to the inner wall of the sliding frame 7, a guide striking component 3 is bolted to the inner wall of the inner drum 2, a rotating shaft 8 is arranged on the inner wall of the inner drum 2, a mounting block 9 is bolted to the surface of the rotating shaft 8, and a striking mixing structure 5 is bolted to the top and bottom of the mounting block 9, and by arranging the outer drum 1, the driving frame 6, the inner drum 2, the sliding frame 7, the flexible connection structure 4, the guide striking component 3, the rotating shaft 8, the mounting block 9 and the striking mixing structure 5 First, the combination of the outer drum 1 and the driving frame 6 provides a basic framework for the entire deburring device. The driving frame 6, as a power support component, can ensure that the outer drum 1 performs stable rotational motion at a predetermined speed and direction. The outer drum 1 not only protects the internal components, but its inner wall also provides a limited space for the operation of the inner drum 2, so that the inner drum 2 can maintain a stable trajectory during rotation to avoid deviation or shaking, thereby ensuring the movement stability of the spring washer during the deburring process and reducing the problem of inconsistent deburring effects caused by irregular movement. The inner drum 2 cooperates with the flexible connection structure 4 of the outer drum 1 through the sliding frame 7 on the surface. The sliding connection method of the sliding frame 7 and the flexible connection structure 4 makes the inner drum 2 While the roller 2 rotates with the outer roller 1, it also has a certain degree of relative independence and flexibility. When the inner roller 2 is subjected to the force of the internal striking and mixing structure 5, it can produce an oscillating motion relative to the outer roller 1 within a certain range. This oscillating motion has an improved effect on the all-round deburring effect of the spring washer, so that the spring washer is no longer simply rolling in the inner roller 2, but can rub and collide with the grinding medium in multiple dimensions, ensuring that all surfaces of the washer, including the inner and outer circumferential surfaces, upper and lower planes, and edge corners, can be fully deburred, thereby improving the thoroughness and uniformity of the deburring. The guide striking assembly 3 on the inner wall of the inner roller 2 and the striking and mixing structure 5 on the rotating shaft 8 cooperate with each other to form An efficient deburring power structure, the guide striking component 3 can not only guide the movement path of the spring washer in the inner drum 2, but also ensure that the striking block 301 can accurately transmit the impact force to the spring washer when it is hit by the striking mixing structure 5, so that the washer is continuously impacted and vibrated during the movement, further enhancing the separation effect of the burr and the washer body. The striking mixing structure 5 rotates under the drive of the rotating shaft 8, so that the striking mixing structure 5 can produce multi-angle and multi-force striking actions during the rotation process, continuously and forcefully stirring and striking the spring washer, prompting the washer to be fully mixed with the grinding medium and produce strong friction, thereby quickly and effectively removing burrs and improving the efficiency and quality of deburring.

[0045] like Figure 6 As shown, the inner drum 2 includes a rotating frame 201, a filter screen 202 and a reinforcing block 203. The surface of the reinforcing block 203 is bolted to the inner wall of the rotating frame 201, the surface of the filter screen 202 is bolted to the inner wall of the rotating frame 201, the inner wall of the filter screen 202 is bolted to the surface of the reinforcing block 203, and the inner wall of the sliding frame 7 is bolted to the surface of the rotating frame 201. By setting the rotating frame 201, the filter screen 202 and the reinforcing block 203, the rotating frame 201 in the inner drum 2 provides a main support frame for the entire inner drum 2 structure, ensuring the integrity and stability of the inner drum 2, so that it can The filter screen 202 can prevent the spring washers from accidentally falling out of the pores of the inner drum 2 during the deburring process, thereby ensuring the safety and stability of the processing process. At the same time, it is also convenient for the subsequent centralized cleaning of these debris and keeps the inside of the outer drum 1 clean. The reinforcing block 203 further enhances the structural strength of the rotating frame 201, especially when it is subjected to the impact force of hitting the mixing structure 5 and the friction force of the spring washers, it can effectively prevent the deformation or damage of the rotating frame 201.

[0046] like Figure 6 As shown, the guide striking assembly 3 includes a striking block 301 and a spiral guide plate 302. The side of the reinforcing block 203 close to the spiral guide plate 302 is bolted to the spiral guide plate 302. The inner wall of the striking block 301 is bolted to the surface of the spiral guide plate 302. The surface of the spiral guide plate 302 is bolted to the inner wall of the filter screen 202. By setting the striking block 301 and the spiral guide plate 302, the spiral guide plate 302 provides a guiding method for the spring washer to circulate along a specific path through its unique spiral shape, so that the spring washer can pass through each key point in sequence while rotating with the inner drum 2. The grinding area of ​​the key can avoid the situation that some areas are over-grinded and other areas are under-grinded, thereby improving the uniformity and comprehensiveness of deburring. Moreover, when the striking mixing structure 5 hits the striking block 301, the striking block 301 transmits the impact force to the spiral guide plate 302, and then to the spring washer, so that the washer is subjected to additional impact and vibration during the movement. This impact vibration can effectively destroy the bonding force between the burr and the washer body, further promote the shedding of the burr, enhance the deburring effect, and enable some more stubborn burrs to be completely removed, thereby improving the surface quality and performance of the product.

By arranging the fixed ring 401, the buffer component 402, the movable frame 403 and the slider 404, The fixed ring 401 in the flexible connection structure 4 serves as a basic component connected to the inner wall of the outer drum 1, and plays a role in fixing and supporting the entire flexible connection structure 4, ensuring the stability of the flexible connection structure 4 during operation. The combination of the movable frame 403 and the slider 404 enables the inner drum 2 and the outer drum 1 to maintain a certain connection relationship while having relative freedom of movement. The buffer component 402 can effectively absorb and buffer the impact force generated during the oscillation of the inner drum 2, prevent these impact forces from being directly transmitted to the outer drum 1, and avoid deformation, loosening or damage of the outer drum 1 due to excessive impact, thereby ensuring the stability and reliability of the entire device.

[0048] like Figure 5 As shown, the buffer assembly 402 includes a connecting block 402a, a damping structure 402b and a fixed block 402c. The side of the fixed block 402c close to the movable frame 403 is bolted to the movable frame 403, the side of the damping structure 402b close to the fixed block 402c is bolted to the fixed block 402c, the side of the connecting block 402a close to the damping structure 402b is bolted to the damping structure 402b, and the side of the connecting block 402a close to the inner wall of the fixed ring 401 is bolted to the fixed ring 401. By setting the connecting block 402a, the damping structure 402b and the fixed block 402c, the impact force of the inner drum 2 is transmitted to the damping structure 402b, thereby effectively reducing the peak value of the impact force and avoiding damage to the outer drum 1. The connecting block 402a connects the damping structure 402b with the fixed ring 401, ensuring the continuity and stability of the buffering process, so that the entire buffer assembly 402 can function efficiently.

The guide striking assembly 3 on the inner wall of the inner drum 2 can effectively guide the movement trajectory of the material in the drum, ensuring that each part of the washer can be fully polished. The outer drum 1 and the driving frame 6 constitute the basic framework of the device. The driving frame 6 as a power support can ensure that the outer drum 1 rotates stably at a predetermined speed and direction. The inner wall of the outer drum 1 provides a limited space for the operation of the inner drum 2, so that its trajectory is stable, deviation and shaking are avoided, the stability of the washer movement is ensured, and the difference in deburring effect caused by irregular movement is reduced. After preparation, start the driving frame 6 to drive the outer drum 1 to start the drum grinding and deburring operation.

[0050] Embodiment 2:

The surface of the rotating shaft 8 is rotatably connected to the inner wall of the limit frame 10, and the left side of the output component 11 is bolted to the right side of the rotating shaft 8. By setting the limit frame 10 and the output component 11, the limit frames 10 on both sides of the outer drum 1 support and position the rotating shaft 8, ensuring that the rotating shaft 8 always maintains a stable axial position during the rotation process, avoiding the normal operation of the striking mixing structure 5 due to the offset or shaking of the rotating shaft 8, thereby ensuring the stability and reliability of the deburring process. The output component 11 is connected to the rotating shaft 8, and can output and transmit the rotational power of the rotating shaft 8.

[0052] like Figure 8As shown, the striking mixing structure 5 includes a rotating sleeve assembly 504, a striking part 503, a torsion spring 502 and a connecting plate 501. The connecting plate 501 is bolted to the mounting block 9 on one side close to the mounting block 9, the left side of the torsion spring 502 is fixedly connected to the inner wall of the connecting plate 501, the right side of the torsion spring 502 is fixedly connected to the left side of the striking part 503, the surface of the striking part 503 is rotatably connected to the inner wall of the connecting plate 501, and the inner wall of the rotating sleeve assembly 504 is rotatably connected to the surface of the striking part 503. By arranging the rotating sleeve assembly 504, the striking part 503, the torsion spring 502 and the connecting plate 501, the connecting plate 501 in the striking mixing structure 5 is used as an installation basis to firmly connect the entire structure to the mounting block 9, thereby ensuring that the striking mixing structure 5 can rotate stably under the drive of the rotating shaft 8, and the torsion spring 502 is arranged to provide the striking part 503 with a stable rotation. Elastic potential energy is provided, so that the striking part 503 can generate elastic striking action during the rotation process. This elastic striking not only increases the diversity and randomness of the striking force, but also enables the striking part 503 to rebound quickly after contacting the guide striking component 3, preparing for the next strike, thereby improving the striking frequency and efficiency. The cooperation between the striking part 503 and the rotating sleeve component 504 further enhances the striking effect. The rotating sleeve component 504 can rotate relatively during the rotation of the striking part 503, so that the striking mixing structure 5 can generate multi-angle and multi-force striking actions during rotation, and the spring washer is more fully and strongly stirred and struck, which promotes the washer and the grinding medium to be fully mixed and produce strong friction, thereby quickly and effectively removing burrs, improving the efficiency and quality of deburring, and meeting the needs of efficient production.

[0053] like Fig. 9 As shown, the rotating sleeve assembly 504 includes a rotating cylinder 504a and a protruding block 504b, and the protruding block 504b is bolted to the rotating cylinder 504a on one side close to the rotating cylinder 504a, and the inner wall of the rotating cylinder 504a is rotatably connected to the surface of the striking part 503. By arranging the rotating cylinder 504a and the protruding block 504b, the rotating cylinder 504a in the rotating sleeve assembly 504 provides a mounting base for the protruding block 504b, and at the same time, the rotating cylinder 504a itself can rotate on the surface of the striking part 503. This rotation characteristic increases the relative movement between the rotating sleeve assembly 504 and the striking part 503, and further enriches the form and effect of the striking action. The protruding block 504b, through its protruding shape, can generate more complex friction and impact force changes during the interaction with the striking part 503, so that the striking part 503 is subjected to more directions and forces of different sizes when rotating, so that the striking hybrid structure 5 can perform more diversified and high-intensity striking on the spring washer as a whole, further improving the efficiency and effect of deburring.

[0054] like Fig. 9As shown, the striking part 503 includes a striking frame 503c, a rotating block 503b and a rotating plate 503a, the right side of the rotating plate 503a is bolted to the left side of the rotating block 503b, the left side of the rotating plate 503a is fixedly connected to the right side of the torsion spring 502, the side of the striking frame 503c close to the rotating block 503b is bolted to the rotating block 503b, and the inner wall of the rotating cylinder 504a is rotatably connected to the surface of the striking frame 503c. By arranging the striking frame 503c, the rotating block 503b and the rotating plate 503a, the striking frame 503c in the striking part 503 is the part that directly contacts and acts with the spring washer and the guide striking assembly 3, and its solid structure can withstand high-speed rotation and frequent striking. The impact force generated ensures the effectiveness and reliability of the striking action. The rotating block 503b is connected to the striking frame 503c, which plays the role of connecting and transmitting the rotational force, so that the striking frame 503c can generate a stable rotational motion with the rotation of the rotating shaft 8, thereby realizing continuous striking of the spring washer. The connection between the rotating plate 503a and the torsion spring 502 provides the striking frame 503c with elastic striking ability, so that it can produce elastic deformation and rebound when in contact with other components, increasing the flexibility and diversity of the striking action, further enhancing the deburring effect on the spring washer, and allowing the burrs to fall off from the washer surface more thoroughly, thereby improving the surface quality and performance of the spring washer.

[0055] Brief description of the use process: By setting up the striking and mixing structure 5, when the driving frame 6 drives the outer drum 1 to rotate, with the help of the flexible connection structure 4, the rotation of the outer drum 1 is transmitted to the inner drum 2, causing it to rotate accordingly. At this time, the rotating shaft 8 in the inner drum 2 drives the striking and mixing structure 5 to rotate, and the rotating striking and mixing structure 5 continuously strikes the surface of the guide striking component 3. The striking force generated makes the inner drum 2 vibrate on the inner wall of the outer drum 1. This vibration allows the spring washer to continuously change its position and posture during the friction deburring process with the grinding medium, thereby achieving effective grinding of burrs in all directions and ensuring the thoroughness and uniformity of deburring. At the same time, the flexible connection structure 4 can effectively absorb and buffer the impact force generated by the vibration of the inner drum 2, prevent it from interfering with the normal rolling of the outer drum 1, and maintain the stable operation of the entire deburring device.

[0056] A preparation process of a multi-directional deburring device for producing spring washers, comprising the following steps:

[0057] S1. First, pour the spring washer material to be deburred into the inner drum 2 through the opening on the inner drum 2. At this time, suitable grinding media, such as sand, ceramic beads, etc., are placed on the inner wall of the outer drum 1 in advance. These grinding media will fully contact with the spring washer during the subsequent rotation of the inner drum 2 and the outer drum 1 to remove the burrs. The guide striking assembly 3 arranged on the inner wall of the inner drum 2 includes a striking block 301 and a spiral guide plate 302, which can guide the movement path of the material in the drum so that each part of the washer can get sufficient grinding opportunities. After preparation, start the driving frame 6 to drive the outer drum 1 to start the drum grinding and deburring operation;

[0058] S2. When the driving frame 6 drives the outer roller 1 to start rotating, since the outer roller 1 and the inner roller 2 are connected by the flexible connection structure 4, the rotation of the outer roller 1 will be transmitted to the inner roller 2 through the flexible connection structure 4, so that the inner roller 2 rotates accordingly. In this process, the rotating shaft 8 in the inner roller 2 also starts to rotate, thereby driving the striking mixing structure 5 to rotate. The rotating striking mixing structure 5 will continuously strike the surface of the guide striking component 3. Due to the action of the striking force, the inner roller 2 will produce an oscillation effect on the inner wall of the outer roller 1. This oscillation makes the spring washer constantly change its position and posture during the friction deburring process with the grinding medium, ensuring that burrs in all directions can be effectively polished. At the same time, the flexible connection structure 4 can effectively absorb and buffer the impact force generated by the vibration of the inner roller 2, ensuring that the normal rolling of the outer roller 1 is not affected, and maintaining the stable operation of the entire deburring device.
