Description

Technical Field

[0001] This invention belongs to the field of bearing processing technology, specifically a high-precision metal bearing casting processing device. Background Technology

[0002] Metal bearings are generally composed of bearing rings and bearing balls. When grinding the bearing balls inside a typical metal bearing, ultrasonic vibration technology is usually used to make the bearing balls move and grind inside, so that the diameter of the bearing balls reaches the standard diameter under the grinding action.

[0003] Currently, when companies grind bearing steel balls, the diameter of each ball varies due to manufacturing errors. When these balls are ground together, the first ball to reach the acceptable diameter continues to move inside. Because it cannot be removed in time, and due to its own weight, the bottom of the ball continues to contact the grinding device and be ground, resulting in the diameter of the ball being smaller than the standard diameter and thus making it unqualified.

[0004] When bearing steel balls are ground inside a grinding device, the process of putting them in and taking them out is usually done as a whole. This results in some bearing steel balls being under-ground and others being over-ground, requiring selection and secondary grinding. This increases the workload of the workers and reduces the product qualification rate. Furthermore, due to the overall feeding method, the grinding device must be stopped every time a ball is added, making it impossible to carry out uninterrupted feeding and grinding operations, thus reducing the grinding efficiency of the bearing steel balls.

[0005] When bearing steel balls are being ground, the metal powder that falls off the surface of the bearing steel balls falls into the ball's movement groove as they are ground inside the grinding device. This causes the lower surface of the bearing steel ball to come into contact with both the metal powder and the grinding wall simultaneously, increasing the grinding area of ​​the bearing steel ball. This results in uneven stress on the outer surface of the bearing steel ball, causing deformation during grinding. Therefore, improvements and optimizations are needed. Summary of the Invention

[0006] The purpose of this invention is to provide a high-precision metal bearing casting processing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-precision metal bearing casting processing device, comprising a chassis and an ultrasonic generator, wherein the ultrasonic generator is located inside the chassis, a lower grinding disc is provided on the top of the chassis, and an upper grinding disc is provided on the top of the lower grinding disc, wherein steel balls are placed inside the chassis and on the contact surfaces between the lower and upper grinding discs, a first fixing plate is fixedly installed on the right end of the top of the upper grinding disc, and a first lifting mechanism is movably installed on the top of the first fixing plate, the first lifting mechanism including a first curved panel, movable rods being fixedly installed on both sides of the first curved panel, and a limit mechanism being provided inside the upper grinding disc. A second lifting mechanism is movably installed inside the grinding disc. A second power mechanism is fixedly installed on the top of the chassis. A first air intake mechanism and a housing are fixedly installed on the top of the chassis. The first air intake mechanism and the housing are connected by a connecting pipe. A first one-way valve located at the top of the connecting pipe is fixedly installed inside the housing. An exhaust block is fixedly installed on the top of the housing. A first pressure valve located at the bottom of the exhaust block is fixedly installed inside the housing. A nozzle is fixedly connected to the left end of the housing. A second pressure valve located at the right end of the nozzle is fixedly installed inside the housing. A collection box is fixedly installed on the left end of the chassis. A second air intake mechanism is fixedly installed at the bottom of the first air intake mechanism.

[0008] After opening the upper grinding disc, place the steel balls between the lower and upper grinding discs. Activate the second power mechanism, causing the first air intake mechanism to inflate the housing. The housing has first and second air pressure values, with the second pressure value being greater than the first. When the internal air pressure exceeds the first pressure value, the first pressure valve opens, reducing the pressure to the first value. Power is then supplied to the second air intake mechanism, causing it to operate. The operation of the second air intake mechanism vibrates the steel balls inside the lower and upper grinding discs, causing them to move in one direction within the discs. Abrasive particles are present on the contact surfaces between the steel balls and the grinding discs, thus grinding the steel balls. As the steel balls grind internally, when the diameter of the steel balls... After being ground to the standard diameter and moving to the bottom of the first fixed plate, since both the first fixed plate and the top of the chassis are equipped with metal plates, when a steel ball with a diameter larger than the standard enters the bottom of the first fixed plate, it will contact or squeeze the first curved panel to move upward. At this time, under the transmission of the steel ball, the circuit between the chassis and the first fixed plate is connected. When a steel ball with a diameter of the standard or smaller moves to the bottom of the first fixed plate, the steel ball cannot connect the first fixed plate and the chassis, thereby triggering the first pressure valve to close. At this time, the air pressure inside the shell rises rapidly. When the air pressure rises to a value greater than or equal to the second air pressure value, the second pressure valve opens instantly, allowing the gas inside the shell to be released through the nozzle. The gas will impact the steel ball, causing the steel ball to detach into the collection box.

[0009] Based on the diameter of the steel balls, a connection is established between the steel balls, the first fixed plate, and the chassis to determine whether the steel balls meet the standard. Then, the gas inside the shell blows the steel balls with diameters below the standard, causing them to detach from the lower and upper grinding discs and enter the collection box. Compared with traditional devices, this device utilizes the diameter of the steel balls and their conductivity to create a segment or passage between the steel balls, the first fixed plate, and the chassis, thereby controlling the opening and closing states of the first and second pressure valves. A strong instantaneous airflow impacts the steel balls, causing them to detach. This ensures that standard steel balls can be promptly detached from the lower and upper grinding discs, preventing over-grinding. Furthermore, the use of gas to propel the steel balls, compared to traditional mechanical devices, allows for the propulsion of steel balls that need to detach without affecting the movement of other steel balls.

[0010] Preferably, a first power mechanism is fixedly installed at the bottom of the chassis, a feed port is opened on the front of the chassis, two vertical plates are fixedly installed at the bottom of the chassis, a movable wheel is movably installed between the two vertical plates, a second moving plate is fixedly installed on the outer surface of the movable wheel, and the right end of the movable wheel is fixedly connected to the first power mechanism.

[0011] The operation of the first power mechanism will cause the movable wheel and the second moving plate to rotate. When the chassis and the first fixed plate lose contact, the second motor and the first motor will start simultaneously. The operation of the second motor will cause the steel ball of standard diameter to be impacted and detached by the powerful instantaneous gas. At the same time, the operation of the first motor will cause the movable wheel and the second moving plate to rotate together. The movement of the second moving plate will push a steel ball to move upward by one steel ball height and enter the position of the detached steel ball. At this time, the steel ball will contact the first fixed plate and connect the circuit. Under the push of the subsequent steel balls, it will smoothly enter the interior of the lower grinding plate and the upper grinding plate for grinding.

[0012] The operation of the first power mechanism causes the movable wheel and the second motion plate to rotate together. The second motion plate pushes the steel ball to the left by one notch, and pushes the steel ball at the left end to the right by one notch, replacing the detached steel ball. Compared with the traditional device, this device can remove steel balls with qualified diameter and length while feeding steel balls, so that the grinding operation is uninterrupted, greatly improving the grinding efficiency, and realizing the synchronous function of feeding and unloading.

[0013] Preferably, the chassis has a second groove located below the lower grinding disc, and the chassis has a hole inside, the bottom end of which passes through the lower grinding disc and extends into the second groove. The chassis also has a third groove located at the right end of the second groove. Both sides of the housing are fixedly connected to vent pipes, the other end of which is connected to the second groove. A third pressure valve located at the left end of the vent pipe is fixedly installed inside the housing.

[0014] When the steel balls are grinding inside the lower and upper grinding discs, the metal powder falling off the surface of the steel balls will enter the second groove through the holes under the action of the steel balls and the squeezing action. Due to the operation of the second motor, the inside of the housing is in a state of inflation. When the air pressure inside the housing reaches or exceeds the first air pressure value, the first pressure valve and the third pressure valve will be opened, so that the gas inside the housing will be slowly discharged through the exhaust block and the vent pipe. At this time, the gas entering the vent pipe will enter the second groove, and the metal powder inside the second groove will be carried out to the outside through the third groove.

[0015] The metal powder, propelled by the movement of the steel balls through the holes, enters the second groove. Gas from inside the casing then carries the powder into the groove, expelling it to the outside. Compared to traditional devices, this system utilizes the movement of the steel balls during grinding to draw the powder into the second groove, while simultaneously using airflow to expel it. This prevents uneven grinding of the steel balls by the powder and avoids clogging the second groove. The combined action of the vent pipe and exhaust block cools the outer surfaces of the lower and upper grinding discs, preventing overheating and extending the equipment's lifespan.

[0016] Preferably, the first lifting mechanism further includes a first moving rod, the bottom end of which passes through the first fixed plate. The top of the first curved panel is fixedly connected to the bottom end of the first moving rod. A first spring, elastically supported between the first curved panel and the first fixed plate, is movably sleeved on the outer surface of the first moving rod. Due to the design of the first curved panel, when a steel ball with a diameter larger than the standard diameter enters the bottom end of the first fixed plate, it will press the first fixed plate upward. At this time, the first spring is in a state of elastic compression, which facilitates good adaptability to steel balls with a diameter larger than the standard diameter.

[0017] Preferably, the first air intake mechanism includes a housing, a first moving plate, and a crossbar. The first moving plate is movably installed inside the housing. The right end of the first moving plate is hinged to the crossbar, and the other end of the crossbar is hinged to a second power mechanism. The second air intake mechanism includes an air intake pipe. A second one-way valve is installed inside the air intake pipe. When the crossbar moves to the right, it will drive the first moving plate to move together. At this time, the first one-way valve is in the closed state, and the second one-way valve is in the open state. At this time, air from the outside is drawn in through the air intake pipe. When the crossbar moves to the left, it will drive the first moving plate to move together. At this time, the second one-way valve is in the closed state, and the first one-way valve is in the open state, allowing gas to enter the interior of the housing through the connecting pipe.

[0018] Preferably, the limiting mechanism includes a first groove, and a moving block is movably installed inside the first groove. Due to the design of the first groove, it can play a good limiting effect on the first curved panel, making the movement of the first curved panel more stable. Due to the design of the moving block, when the moving block is located at the lowest end inside the first groove, the first curved panel is at its lowest position, which is also the standard diameter height position.

[0019] Preferably, the second power mechanism includes a second motor, a second horizontal shaft, a second fixed plate, and a circular block. The second fixed plate is fixedly installed on the top of the chassis. The output shaft of the second motor is movably connected to the second horizontal shaft. The second horizontal shaft passes through the second fixed plate and is fixedly installed with the circular block. The left end of the circular block is hinged to the crossbar. Due to the operation of the second motor, the circular block will rotate, and the rotation of the circular block will drive the crossbar to move left and right.

[0020] Preferably, the second lifting mechanism includes a second curved panel, a second moving rod, and a second spring. The second moving rod is fixedly installed on the top of the second curved panel. The top of the second moving rod passes through the upper grinding disc. The outer surface of the second moving rod is movably sleeved with a second spring that is elastically supported between the top of the inner cavity of the upper grinding disc and the second curved panel. Due to the design of the second spring, it can exert downward pressure on the steel ball, so that the top of the steel ball is in close contact with the second curved panel, and at the same time, it can achieve a good grinding effect.

[0021] Preferably, the first power mechanism includes a first motor, the output shaft of which is movably connected to a first horizontal shaft. The operation of the first horizontal shaft will cause it to rotate, thereby driving the vertical plate and the movable wheel to rotate, thus providing power.

[0022] Preferably, the connection between the chassis and the collection box is provided with a ramp. Due to the design of the ramp, the movement of the steel ball can be well guided, allowing the steel ball to smoothly enter the interior of the collection box and preventing it from deviating.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention, by setting a first fixed plate, a first pressure valve, and a second pressure valve, determines whether the steel ball meets the standard by establishing a communication relationship between the steel ball, the first fixed plate, and the chassis based on the diameter of the steel ball. Then, the gas inside the housing blows the steel balls with diameters below the standard, causing them to detach from the lower and upper grinding discs and enter the collection box. Compared with traditional devices, this device utilizes the diameter of the steel ball and its conductivity to create a circuit (open or closed) between the steel ball, the first fixed plate, and the chassis, thereby controlling the opening and closing states of the first and second pressure valves. A strong, instantaneous airflow impacts the steel ball, causing it to detach. This ensures that standard-compliant steel balls can be promptly detached from the lower and upper grinding discs, preventing over-grinding. Furthermore, the use of gas to propel the steel ball, compared to traditional mechanical devices, allows for the propulsion of steel balls without affecting the movement of other steel balls.

[0025] 2. This invention, by setting up a first power mechanism, a movable wheel, and a second motion plate, causes the movable wheel and the second motion plate to rotate together through the operation of the first power mechanism. The second motion plate pushes the steel ball to the left by one notch, and pushes the steel ball at the left end to move upward by one notch to replace the detached steel ball. Compared with traditional devices, this device can simultaneously remove steel balls with qualified diameter and length while feeding steel balls, making the grinding operation uninterrupted and greatly improving the grinding efficiency. At the same time, it realizes the synchronous function of feeding and unloading.

[0026] 3. This invention, by setting a second groove, holes, and a vent pipe, allows metal powder to enter the interior of the second groove through the holes under the movement of the steel balls. Then, the gas inside the casing carries the metal powder to the outside. Compared to traditional devices, this device utilizes the movement of the steel balls during grinding to carry the metal powder into the second groove, while simultaneously using wind power to expel the metal powder to the outside. This prevents uneven grinding force on the steel balls caused by metal powder and also prevents metal powder from clogging the second groove. The combined action of the vent pipe and exhaust block cools the outer surfaces of the lower and upper grinding discs, preventing excessive grinding temperature and improving the equipment's service life.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0040] like Figures 1 to 11As shown in the embodiment of the present invention, a high-precision metal bearing casting processing device includes a chassis 1 and an ultrasonic generator 35. The ultrasonic generator 35 is located inside the chassis 1. A lower grinding disc 2 is provided on the top of the chassis 1, and an upper grinding disc 3 is provided on the top of the lower grinding disc 2. Steel balls 4 are placed inside the chassis 1 and on the contact surfaces between the lower grinding disc 2 and the upper grinding disc 3. A first fixing plate 5 is fixedly installed on the right end of the top of the upper grinding disc 3. A first lifting mechanism 6 is movably installed on the top of the first fixing plate 5. The first lifting mechanism 6 includes a first curved panel 62. Movable rods 9 are fixedly installed on both sides of the first curved panel 62. A limit mechanism 10 is provided inside the upper grinding disc 3, and a second lifting mechanism is movably installed inside the upper grinding disc 3. The chassis 1 has a second power mechanism 14 fixedly installed on the top of the chassis 1, a first air intake mechanism 16 and a housing 17 fixedly installed on the top of the chassis 1, the first air intake mechanism 16 and the housing 17 are connected by a connecting pipe 18, a first one-way valve 19 is fixedly installed inside the housing 17 at the top of the connecting pipe 18, an exhaust block 20 is fixedly installed on the top of the housing 17, a first pressure valve 21 is fixedly installed inside the housing 17 at the bottom of the exhaust block 20, a nozzle 22 is fixedly connected to the left end of the housing 17, a second pressure valve 23 is fixedly installed inside the housing 17 at the right end of the nozzle 22, a collection box 24 is fixedly installed on the left end of the chassis 1, and a second air intake mechanism 34 is fixedly installed at the bottom of the first air intake mechanism 16.

[0041] After opening the upper grinding disc 3, place the steel ball 4 between the lower grinding disc 2 and the upper grinding disc 3. Start the second power mechanism 14, causing the first air intake mechanism 16 to inflate the interior of the housing 17. The housing 17 has first and second air pressure values, with the second pressure value being greater than the first. When the air pressure inside the housing 17 exceeds the first pressure value, the first pressure valve 21 will open, reducing the air pressure to the first pressure value. This connects the power to the second air intake mechanism 34, causing it to start working. The operation of the second air intake mechanism 34 will vibrate the steel ball 4 inside the lower and upper grinding discs 2 and 3, causing the steel ball 4 to move in one direction within the lower and upper grinding discs 2 and 3. Abrasive particles are present on the contact surfaces between the steel ball 4 and the lower and upper grinding discs 2 and 3, thus grinding the steel ball 4. When the steel ball 4 is grinding internally, when the steel ball 4 is in a straight line... When the steel ball 4, which is larger than the standard diameter, moves to the bottom of the first fixed plate 5 after being ground to the standard diameter, it will contact or press the first curved panel 62 to move upward. At this time, under the transmission of the steel ball 4, the circuit between the chassis 1 and the first fixed plate 5 is connected. When the steel ball 4, which is at or below the standard diameter, moves to the bottom of the first fixed plate 5, the steel ball 4 cannot connect the first fixed plate 5 and the chassis 1, thereby triggering the first pressure valve 21 to close. At this time, the air pressure inside the housing 17 rises rapidly. When the air pressure rises to a value greater than or equal to the second air pressure value, the second pressure valve 23 opens instantly, allowing the gas inside the housing 17 to be released through the nozzle 22. The gas will impact the steel ball 4, causing the steel ball 4 to detach into the collection box 24.

[0042] Based on the diameter of the steel ball 4, a connection is established between the steel ball 4, the first fixing plate 5, and the chassis 1 to determine whether the steel ball 4 meets the standard. Then, the gas inside the housing 17 blows the steel balls 4 with diameters below the standard, causing them to detach from the lower grinding disc 2 and the upper grinding disc 3 and enter the collection box 24. Compared with traditional devices, this device utilizes the diameter of the steel ball 4 and its conductivity to create a circuit between the steel ball 4, the first fixing plate 5, and the chassis 1, thereby controlling the opening and closing states of the first pressure valve 21 and the second pressure valve 23. A strong instantaneous airflow impacts the steel ball 4, causing it to detach. This ensures that the standard steel balls 4 can be promptly detached from the lower grinding disc 2 and the upper grinding disc 3, preventing over-grinding. Furthermore, the use of gas to propel the steel ball 4, compared to traditional mechanical devices, allows for the propulsion of steel balls 4 without affecting the movement of other steel balls 4.

[0043] The chassis 1 has a first power mechanism 12 fixedly installed at the bottom end, a feed inlet 25 on the front of the chassis 1, a vertical plate 26 fixedly installed at the bottom end of the chassis 1, two vertical plates 26, a movable wheel 27 movably installed between the two vertical plates 26, a second moving plate 28 fixedly installed on the outer surface of the movable wheel 27, and the right end of the movable wheel 27 fixedly connected to the first power mechanism 12.

[0044] The operation of the first power mechanism 12 will cause the movable wheel 27 and the second moving plate 28 to rotate. When the chassis 1 and the first fixed plate 5 are disconnected, the second motor 141 and the first motor 121 will be triggered to start simultaneously. Due to the operation of the second motor 141, the steel ball 4 of the standard diameter will be impacted and detached by the powerful instantaneous gas. At the same time, due to the operation of the first motor 121, the movable wheel 27 and the second moving plate 28 will rotate together. The movement of the second moving plate 28 will push a steel ball 4 to move, so that the steel ball 4 moves upward by the pushing action and enters the position of the detached steel ball 4. At this time, the steel ball 4 will contact the first fixed plate 5 and connect the circuit. Under the push of the subsequent steel ball 4, it will smoothly enter the interior of the lower grinding plate 2 and the upper grinding plate 3 for grinding.

[0045] The operation of the first power mechanism 12 causes the movable wheel 27 and the second motion plate 28 to rotate together. The second motion plate 28 pushes the steel ball 4 to move one position to the left, and pushes the steel ball 4 at the left end to move one position upward and replace the detached steel ball 4. Compared with the traditional device, this device can remove steel balls 4 with qualified diameter and length while feeding steel balls 4, so that the grinding operation is uninterrupted, greatly improving the grinding efficiency, and realizing the synchronous function of feeding and unloading.

[0046] The chassis 1 has a second groove 29 located below the lower grinding disc 2 inside. The chassis 1 has a hole 30 inside. The bottom end of the hole 30 passes through the lower grinding disc 2 and extends into the second groove 29. The chassis 1 has a third groove 31 located at the right end of the second groove 29 inside. Both sides of the housing 17 are fixedly connected to vent pipes 32. The other end of the vent pipes 32 is connected to the second groove 29. A third pressure valve 33 located at the left end of the vent pipe 32 is fixedly installed inside the housing 17.

[0047] When the steel ball 4 is grinding inside the lower grinding disc 2 and the upper grinding disc 3, the metal powder falling off the surface of the steel ball 4 will enter the second groove 29 through the hole 30 under the action of the movement and compression of the steel ball 4. Due to the operation of the second motor 141, the inside of the housing 17 is in a state of inflation. When the air pressure inside the housing 17 reaches or exceeds the first air pressure value, the first pressure valve 21 and the third pressure valve 33 will be opened, so that the gas inside the housing 17 is slowly discharged through the exhaust block 20 and the vent pipe 32. At this time, the gas entering the vent pipe 32 will enter the second groove 29, and the metal powder inside the second groove 29 will be carried out to the outside through the third groove 31.

[0048] Under the movement of the steel ball 4 through the hole 30, the metal powder enters the interior of the second groove 29. Then, the gas inside the housing 17 enters the interior of the second groove 29, thereby carrying the metal powder to the outside. Compared with traditional devices, this device can use the movement of the steel ball 4 itself during grinding to carry the metal powder into the interior of the second groove 29. At the same time, it uses wind power to carry the metal powder to the outside, preventing the metal powder from causing uneven grinding force on the steel ball 4 and preventing the metal powder from clogging the second groove 29. With the combined action of the vent pipe 32 and the exhaust block 20, the outer surfaces of the lower grinding disc 2 and the upper grinding disc 3 can be cooled to prevent the grinding temperature from being too high and improve the service life of the equipment.

[0049] The first lifting mechanism 6 also includes a first moving rod 61, the bottom end of which passes through the first fixed plate 5. The top of the first curved panel 62 is fixedly connected to the bottom end of the first moving rod 61. A first spring 63, which is elastically supported between the first curved panel 62 and the first fixed plate 5, is movably sleeved on the outer surface of the first moving rod 61. Due to the design of the first curved panel 62, when a steel ball 4 with a diameter larger than the standard diameter enters the bottom end of the first fixed plate 5, it will press the first fixed plate 5 upward. At this time, the first spring 63 is in a state of elastic compression, which facilitates good adaptation to steel balls 4 with a diameter larger than the standard diameter.

[0050] The first air intake mechanism 16 includes a housing 161, a first moving plate 162, and a crossbar 163. The first moving plate 162 is movably installed inside the housing 161. The right end of the first moving plate 162 is hinged to the crossbar 163, and the other end of the crossbar 163 is hinged to the second power mechanism 14. The second air intake mechanism 34 includes an air intake pipe 341. A second one-way valve 342 is installed inside the air intake pipe 341. When the crossbar 163 moves to the right, it will drive the first moving plate 162 to move together. At this time, the first one-way valve 19 is in the closed state, and the second one-way valve 342 is in the open state. At this time, air from the outside is drawn in through the air intake pipe 341. When the crossbar 163 moves to the left, it will drive the first moving plate 162 to move together. At this time, the second one-way valve 342 is in the closed state, and the first one-way valve 19 is in the open state, so that gas enters the interior of the housing 17 through the connecting pipe 18.

[0051] The limiting mechanism 10 includes a first groove 101, and a moving block 102 is movably installed inside the first groove 101. Due to the design of the first groove 101, it can play a good limiting effect on the first curved panel 62, making the movement of the first curved panel 62 more stable. Due to the design of the moving block 102, when the moving block 102 is located at the lowest end inside the first groove 101, the first curved panel 62 is at its lowest position, which is also the standard diameter height position.

[0052] The second power mechanism 14 includes a second motor 141, a second horizontal shaft 142, a second fixed plate 143, and a circular block 144. The second fixed plate 143 is fixedly installed on the top of the chassis 1. The output shaft of the second motor 141 is movably connected to the second horizontal shaft 142. The second horizontal shaft 142 passes through the second fixed plate 143 and the circular block 144 is fixedly installed thereon. The left end of the circular block 144 is hinged to the crossbar 163. Due to the operation of the second motor 141, the circular block 144 will rotate, and the rotation of the circular block 144 will drive the crossbar 163 to move left and right.

[0053] The second lifting mechanism 11 includes a second curved panel 111, a second moving rod 112, and a second spring 113. The second moving rod 112 is fixedly installed on the top of the second curved panel 111. The top of the second moving rod 112 passes through the upper grinding disc 3. The outer surface of the second moving rod 112 is movably sleeved with the second spring 113, which is elastically supported between the top of the inner cavity of the upper grinding disc 3 and the second curved panel 111. Due to the design of the second spring 113, it can exert downward pressure on the steel ball 4, so that the top of the steel ball 4 is in close contact with the second curved panel 111, and at the same time, it can achieve a good grinding effect.

[0054] The first power mechanism 12 includes a first motor 121, the output shaft of which is movably connected to a first horizontal shaft 122. The operation of the first horizontal shaft 122 will cause it to rotate, thereby driving the vertical plate 26 and the movable wheel 27 to rotate, thus providing power.

[0055] The chassis 1 and the collection box 24 are connected by a ramp. The ramp design can guide the movement of the steel ball 4, allowing the steel ball 4 to smoothly enter the interior of the collection box 24 and preventing it from shifting.

[0056] Working principle and usage process:

[0057] After opening the upper grinding disc 3, place the steel ball 4 between the lower grinding disc 2 and the upper grinding disc 3. Start the second power mechanism 14, causing the first air intake mechanism 16 to inflate the interior of the housing 17. The housing 17 has a first air pressure value and a second air pressure value, with the second air pressure value being greater than the first air pressure value. When the air pressure inside the housing 17 exceeds the first air pressure value, the first pressure valve 21 will open, causing the air pressure to drop to the first air pressure value. Power will then be supplied to the second air intake mechanism 34, causing it to start working. The operation of the second air intake mechanism 34 will vibrate the steel ball 4 inside the lower grinding disc 2 and the upper grinding disc 3, causing the steel ball 4 to move in one direction within the lower grinding disc 2 and the upper grinding disc 3. Abrasive particles are present on the contact surfaces between the lower grinding disc 2 and the upper grinding disc 3 and the steel ball 4, thus performing a grinding operation on the steel ball 4. When the steel ball 4 is grinding internally, when the steel ball... When the steel ball 4, with a diameter greater than the standard diameter, moves to the bottom of the first fixed plate 5 after being ground to the standard diameter, since both the first fixed plate 5 and the top of the chassis 1 are provided with metal plates, when the steel ball 4, with a diameter greater than the standard diameter, enters the bottom of the first fixed plate 5, it will contact or squeeze the first curved panel 62 and move upward. At this time, under the conduction of the steel ball 4, the circuit between the chassis 1 and the first fixed plate 5 is connected. When the steel ball 4, with a diameter of the standard diameter or less than the standard diameter, moves to the bottom of the first fixed plate 5, the steel ball 4 cannot connect the first fixed plate 5 and the chassis 1, thereby triggering the first pressure valve 21 to close. At this time, the air pressure inside the housing 17 rises rapidly. When the air pressure rises to a value greater than or equal to the second air pressure value, the second pressure valve 23 opens instantly, allowing the gas inside the housing 17 to be released through the nozzle 22. The gas will impact the steel ball 4, causing the steel ball 4 to detach into the collection box 24.

[0058] The operation of the first power mechanism 12 will cause the movable wheel 27 and the second moving plate 28 to rotate. When the chassis 1 and the first fixed plate 5 are disconnected, the second motor 141 and the first motor 121 will be triggered to start simultaneously. Due to the operation of the second motor 141, the steel ball 4 of the standard diameter will be impacted and detached by the powerful instantaneous gas. At the same time, due to the operation of the first motor 121, the movable wheel 27 and the second moving plate 28 will rotate together. The movement of the second moving plate 28 will push a steel ball 4 to move, so that the steel ball 4 moves upward by the pushing action and enters the position of the detached steel ball 4. At this time, the steel ball 4 will contact the first fixed plate 5 and connect the circuit. Under the push of the subsequent steel ball 4, it will smoothly enter the interior of the lower grinding plate 2 and the upper grinding plate 3 for grinding.

[0059] When the steel ball 4 is grinding inside the lower grinding disc 2 and the upper grinding disc 3, the metal powder falling off the surface of the steel ball 4 will enter the interior of the second groove 29 through the hole 30 under the action of the movement and compression of the steel ball 4. Due to the operation of the second motor 141, the interior of the housing 17 is in a state of inflation. When the air pressure inside the housing 17 reaches or exceeds the first air pressure value, the first pressure valve 21 and the third pressure valve 33 will be opened, so that the gas inside the housing 17 will be slowly discharged through the exhaust block 20 and the vent pipe 32. At this time, the gas entering the vent pipe 32 will enter the interior of the second groove 29, and the metal powder inside the second groove 29 will be carried out to the outside through the third groove 31.
