Description

Technical Field

[0001] The present invention relates to the technical field of bearing ring processing, and more specifically, to a bearing ring processing feeding device and method thereof. Background Art

[0002] Bearings are important components in contemporary mechanical equipment, used to support rotating mechanical bodies, reduce the friction coefficient during their movement, and ensure their rotational accuracy; bearing rings are important parts of rolling bearings. A bearing ring is an annular part with one or more raceways, mainly used to support and guide the rolling elements in the bearing;

[0003] In the prior art, a chain conveyor is usually used to lift the bearing rings to be processed to a specified height. Then, these bearing rings to be processed are transferred from the chain conveyor to a guiding device. In this guiding device, the bearing rings will roll onto the surface of the processing device in sequence for processing. However, during the transfer of the bearing rings from the chain conveyor to the guiding device, if the bearing rings do not move straight forward, it will cause the bearing rings to hit the surface of the guiding device, which will cause the bearing rings to get stuck in the guiding device, resulting in the entire device being unable to operate continuously, so that workers need to straighten the bearing rings, leading to low work efficiency.

[0004] Therefore, a bearing ring processing feeding device and method thereof are proposed. Summary of the Invention

[0010] Cleaning mechanism, the cleaning mechanism includes an installation groove opened on the limit plate. A roller is evenly and horizontally rotatably installed in the installation groove. A first cavity is opened on the roller. Exhaust valves are evenly embedded on the side wall of the first cavity. A brush cooperating with the exhaust valve is provided on the roller. A first air supply mechanism for supplying gas to the first cavity and an auxiliary cleaning mechanism cooperating with the exhaust valve are provided on the roller;

[0011] Alignment mechanism, the alignment mechanism includes an extrusion rod made of magnetic material slidably installed on the inner side wall of the transfer basket. A first elastic member is provided between the inner side wall of the transfer basket and the extrusion rod. A magnet attracting the extrusion rod is embedded at the top of the side wall of the limit plate, and the surface of the magnet is mirror-like.

[0012] Further, the first air supply mechanism includes a diaphragm made of elastic material horizontally installed in the first cavity. Air inlet valves are symmetrically installed on the side wall of the first cavity, and the air inlet valves are distributed on both sides of the diaphragm.

[0013] Further, two guiding grooves are opened on the inner side wall of the transfer basket. The two guiding grooves are distributed on the inner side walls of the opposite sides of the transfer basket. Sliders are slidably installed in the guiding grooves. Both ends of the extrusion rod are fixedly connected to the corresponding sliders respectively. Both ends of the first elastic member are fixedly connected to the side wall of the guiding groove close to the limit plate and the slider respectively;

[0014] The auxiliary cleaning mechanism includes air holes opened on the side wall of the first cavity. The exhaust valve is embedded in the air holes, and the brushes are evenly installed on the side wall of the air holes. The brushes are made of elastic material, and the ends of the brushes extend outside the air holes. A weight block is embedded on the diaphragm.

[0015] Further, a plug rod is horizontally movably inserted on the side wall of the mounting plate. A movable plate is installed at the end of the plug rod. A second elastic member is installed between the movable plate and the side wall of the mounting plate.

[0016] Further, the side wall of the movable plate close to the plug rod is an inclined surface. A push rod is rotatably installed on the side wall of the mounting plate close to the movable plate, and the push rod is used to push the movable plate to move.

[0017] Further, a second cavity is opened on the bottom wall of the transfer basket. Small holes are evenly opened on the top wall of the second cavity, and a second air supply mechanism cooperating with the second cavity is provided on the first elastic member.

[0018] Further, the second air supply mechanism includes a third cavity opened on the first elastic member. A conduit extending into the second cavity is inserted on the side wall of the third cavity.

[0019] Further, a sealing plate is slidably mounted on the top wall of the third cavity. Activity holes corresponding to the small holes one by one are evenly formed in the sealing plate. An elastic rope is installed between the sealing plate and the side wall of the third cavity. A top rod is slidably inserted into the side wall of the third cavity. The top wall of the end of the top rod located outside the third cavity is beveled, and a baffle plate cooperating with the top rod is installed on the mounting frame. The width ratio of the magnet to the baffle plate is 5:2.

[0020] Further, arc-shaped protective sleeves are evenly installed in the installation groove, and the protective sleeves are made of sponge material.

[0021] A feeding method applicable to the above-mentioned bearing ring processing feeding device includes the following steps:

[0022] S1. Place the workpiece to be processed in the transfer basket, and then start the drive motor. The drive motor drives the sprocket to rotate. At this time, the transfer basket is driven by the chain to move along the circular track on the mounting frame;

[0023] S2. During the movement of the transfer basket, the workpiece contacts the roller. At this time, both the workpiece and the roller are in a rotating state. The gas in the space below the counterweight block in the first cavity is discharged through the exhaust valve and impacts the surface of the workpiece. At the same time, the brush scrapes on the surface of the workpiece;

[0024] S3. When the transfer basket moves to the surface of the magnet, the extrusion rod moves towards the magnet and pushes the workpiece. At the same time, the sealing plate impacts the side wall of the third cavity to drive the transfer basket to vibrate, and the small holes exhaust upward to impact the workpiece, so as to straighten the workpiece. The straightened workpiece rolls onto the surface of the guide plate;

[0025] S4. During the process of the workpiece rolling along the guide plate, the upward moving transfer basket drives the movable plate to intermittently squeeze the workpiece on the surface of the guide plate through the push rod, and straightens the workpiece at any time.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] (1) By setting the roller, diaphragm, and exhaust valve in this solution, the workpiece can be subjected to rolling friction during the upward movement of the transfer basket, reducing the friction force on the surface of the workpiece, preventing scratches on the surface of the workpiece. At the same time, during the rotation of the roller, the diaphragm intermittently bulges downward. When the diaphragm bulges downward, the gas discharged from the exhaust valve located below the diaphragm can impact the surface of the workpiece, blowing away the debris on the surface of the workpiece. Thus, when the workpiece rolls along the guide plate, the workpiece can roll in a straight line, reducing the probability that the workpiece hits the movable plate and is stuck and unable to roll, playing a role in improving work efficiency;

[0028] (2) In this scheme, by providing a brush, the friction between the workpiece and the roller is increased by sandwiching the brush between the roller and the workpiece, thereby ensuring that the workpiece can roll. At the same time, the airflow discharged from the exhaust valve impacts the brush, which can cause the brush to scrape on the surface of the workpiece, further improving the cleaning effect of the workpiece.

[0029] (3) This scheme provides a push rod and a movable plate. When the transfer basket moves upward, the push rod can be pushed to drive the two movable plates to move closer to each other. At this time, the workpiece on the guide plate will be pushed by the movable plate and change its rolling direction, thereby ensuring that the workpiece can roll along a straight line.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0041] Please refer to Figures 1 to 8 , a feeding device for bearing ring processing, including a mounting frame 1, a sprocket 2 is provided on the mounting frame 1, a chain 3 is sleeved on the sprocket 2, mounting rods 4 are evenly arranged on the chain 3, a transfer basket 5 is provided on the mounting rod 4, and a limiting plate 6 cooperating with the transfer basket 5 is installed on the mounting frame 1;

[0042] It further includes:

[0043] A guide plate 7, the guide plate 7 is installed on the mounting frame 1, and mounting plates 8 are symmetrically and fixedly installed on the top wall of the guide plate 7;

[0044] A cleaning mechanism, the cleaning mechanism includes a mounting groove opened on the limiting plate 6, roller cylinders 9 are evenly and horizontally rotatably installed in the mounting groove, the roller cylinders 9 are used to reduce the friction force received by the workpiece, a first cavity 10 is opened on the roller cylinder 9, exhaust valves 11 are evenly embedded on the side wall of the first cavity 10, a brush 19 cooperating with the exhaust valves 11 is provided on the roller cylinder 9, and a first air supply mechanism for supplying gas to the first cavity 10 and an auxiliary cleaning mechanism cooperating with the exhaust valves 11 are provided on the roller cylinder 9;

[0045] An alignment mechanism, the alignment mechanism includes a magnetic extrusion rod 16 slidably installed on the inner side wall of the transfer basket, a first elastic member 17 is provided between the inner side wall of the transfer basket 5 and the extrusion rod 16, a magnet 18 attracting the extrusion rod 16 is embedded at the top of the side wall of the limiting plate 6, and the surface of the magnet 18 is a mirror surface;

[0046] Among them, the chain 3 drives the transfer basket 5 to move. During the movement of the transfer basket 5, the surface impurities of the workpiece are cleaned by the cleaning mechanism and the auxiliary cleaning mechanism to prevent the workpiece from not rolling in a straight line due to impurities on the surface. Then, the alignment mechanism aligns the workpiece about to separate from the transfer basket 5. Finally, the aligned workpiece rolls onto the surface of the guide plate 7.

[0047] The first air supply mechanism includes a diaphragm 12 made of elastic material horizontally installed in the first cavity 10, and air inlet valves 14 are symmetrically installed on the side wall of the first cavity 10, and the air inlet valves 14 are distributed on both sides of the diaphragm 12.

[0048] Two guiding grooves are formed on the inner sidewall of the transfer basket 5. The two guiding grooves are distributed on the inner sidewalls of the opposite sides of the transfer basket 5. Sliders 15 are slidably installed in the guiding grooves. Both ends of the extrusion rod 16 are fixedly connected to the corresponding sliders 15 respectively. Both ends of the first elastic member 17 are fixedly connected to the sidewall of the corresponding guiding groove close to the limiting plate 6 and the slider 15 respectively; The auxiliary cleaning mechanism includes air holes formed on the sidewall of the first cavity 10. The exhaust valve 11 is embedded in the air holes, and the brush 19 is evenly installed on the sidewall of the air holes.

[0049] First, install the driving motor on the annular mounting frame 1, and fix the output end of the driving motor to the rotating shaft of the sprocket 2. Therefore, when the driving motor works, the chain 3 can be driven to rotate along the annular mounting frame 1 by the rotating sprocket 2. At the same time, the mounting rod 4 and the transfer basket 5 move together with the chain 3, and the workpiece loaded in the transfer basket 5 moves together with the transfer basket 5; Since the bottom wall of the transfer basket 5 is inclined towards the guiding plate 7, the workpiece in the transfer basket 5 always has a tendency to roll towards the limiting plate 6, and under the action of the first elastic member 17, the workpiece in the transfer basket 5 is located in the space between the extrusion rod 16 and the limiting plate 6.

[0050] During the process of the transfer basket 5 moving upward along the surface of the limit plate 6, the workpiece in the transfer basket 5 is always in contact with the roller 9 in the installation groove. Therefore, during the rolling process of the workpiece, the roller 9 can be driven to rotate. During the rotation of the roller 9, the diaphragm 12 bulges downward. When the diaphragm 12 bulges downward, the gas in the space below the diaphragm 12 is discharged through the exhaust valve 11. The gas discharged by the exhaust valve 11 impacts the surface of the workpiece, playing a role in cleaning the surface of the workpiece. During the process of air hole exhaust, the gas discharged from the air holes impacts the brush 19 made of elastic material. Since the roller 9 is in a rotating state, part of the brush 19 in contact with the outer wall of the workpiece will shake under the action of the air flow impact force, and the shaking brush 19 scrapes on the surface of the workpiece, thereby being able to assist the air flow in cleaning the surface of the workpiece and playing a role in improving the cleaning effect on the surface of the workpiece; the end of the brush 19 extends outside the air hole, and a counterweight 13 is embedded in the diaphragm 12. Therefore, part of the brush 19 is clamped in the space between the workpiece and the brush 19. At this time, the friction force received by the workpiece is increased, playing a role in ensuring that the workpiece can drive the roller 9 to rotate; and by setting the counterweight 13 on the surface of the diaphragm 12, the deformation amount of the diaphragm 12 can be increased during the flipping process of the diaphragm 12, thereby further increasing the impact force of the gas discharged from the air hole 10 and improving the impact effect on the brush 19. At the same time, the space above the diaphragm 12 sucks air from the outside through the intake valve 14, playing a role in preparing for the next operation; when the transfer basket 5 moves to the top of the limit plate 6 and continues to move upward, the extrusion rod 16 is attracted by the magnet 18, and the attraction force is greater than the elastic force of the first elastic member 17. At this time, the extrusion rod 16 drives the slider 15 to move along the guide groove and applies a thrust to the workpiece, so that the workpiece can be pushed onto the surface of the magnet 18, and the workpiece is aligned by the pressure of the extrusion rod 16 on the workpiece. After the workpiece is aligned, the transfer basket 5 drives the workpiece to move upward along the surface of the magnet 18 with a mirror surface. Finally, when the inner bottom wall of the transfer basket 5 is parallel to the top wall of the guide plate 7, the workpiece will roll onto the surface of the guide plate 7 in an aligned state, and then roll along the guide plate 7 to a specified position for the next processing step. During the entire feeding process, the impurities on the surface of the workpiece are cleaned up, and the workpiece rolling onto the surface of the guide plate 7 is aligned by the extrusion rod 16, reducing the probability of the workpiece changing direction during the rolling process and playing a role in improving the work efficiency.

[0051] As Figure 3 , Figure 5 shown, a plug rod 20 is horizontally movably inserted on the side wall of the mounting plate 8. The end of the plug rod 20 is provided with a movable plate 21. The side wall of the movable plate 21 close to the plug rod 20 is an inclined surface. The plug rod 20 is located at the top of the side wall of the movable plate 21. A second elastic member 22 is installed between the movable plate 21 and the side wall of the mounting plate 8. A push rod 23 is rotatably installed on the side wall of the mounting plate 8 close to the movable plate 21, and the push rod 23 is used to push the movable plate 21 to move.

[0052] By adopting the above technical solution, when the transfer basket 5 is not in contact with the push rod 23, under the action of gravity, the push rod 23 is in a horizontal state, and the push rod 23 is in contact with the bottom end of the side wall of the movable plate 21. During the upward movement of the transfer basket 5, the top wall of the transfer basket 5 is in contact with the push rod 23 and pushes the push rod 23 to rotate upward. During the rotation of the push rod 23, the push rod 23 applies an upward thrust to the inclined surface of the movable plate 21. Since the movable plate 21 can only move in the horizontal direction under the action of the insertion rod 20, as the push rod 23 rotates upward, the movable plate 21 is also pushed by the push rod 23. The second elastic member 22 is stretched, that is, the movable plates 21 on the two mounting plates 8 are close to each other. At this time, the movable plates 21 close to each other squeeze the workpiece, so that the workpiece can be straightened again. When the transfer basket 5 is out of contact with the push rod 23, the push rod 23 flips over and resets, and the second elastic member 22 recovers and stretches the movable plate 21 to reset. At this time, the movable plate 21 is out of contact with the workpiece, and the workpiece rolls smoothly again. Since the transfer baskets 5 are evenly arranged on the chain 3, the workpiece can be squeezed frequently by the movable plate 21, thereby ensuring that the workpiece can roll smoothly.

[0053] like Figure 6 , Figure 7 As shown, a second cavity 24 is formed on the bottom wall of the transfer basket 5 , small holes are evenly formed on the top wall of the second cavity 24 , and a second air supply mechanism cooperating with the second cavity 24 is formed on the first elastic member 17 .

[0054] The second air supply mechanism includes a third cavity 25 formed on the first elastic member 17 , and a conduit 26 extending into the second cavity 24 is inserted into a side wall of the third cavity 25 .

[0055] A sealing plate 27 is slidably mounted on the top wall of the third cavity 25, and movable holes corresponding to the small holes are evenly opened on the sealing plate 27. An elastic rope 28 is installed between the sealing plate 27 and the side wall of the third cavity 25. A push rod 29 is slidably inserted on the side wall of the third cavity 25. The top wall of the end of the push rod 29 located outside the third cavity 25 is an inclined surface, and a baffle 30 cooperating with the push rod 29 is installed on the mounting frame 1, and the ratio of the width of the magnet 18 to the width of the baffle 30 is 5:2.

[0056] By adopting the above technical solution, when the transfer basket 5 has not moved to the surface of the magnet 18, under the action of the elastic rope 28, the movable hole on the sealing plate 27 is aligned with the small hole. At this time, the side wall of the sealing plate 27 is in contact with the side wall of the third cavity 25, and the elastic rope 28 is in a stretched state. During the upward movement of the transfer basket 5, when the transfer basket 5 is about to move to the bottom of the magnet 18, the end of the top rod 29 extending from the third cavity 25 contacts the bottom wall of the baffle 30. At this time, under the action of the inclined surface on the top rod 29, the top rod 29 retracts into the third cavity 25 and drives the sealing plate 27 to move, so that the small hole and the movable hole are misaligned. At this time, the transfer basket 5 moves to the bottom of the magnet 18.

[0057] When the extrusion rod 16 moves along the guide groove, the first elastic member 17 is squeezed, and the volume of the second cavity 24 becomes smaller. The gas in the second cavity 24 is discharged into the third cavity 25 through the conduit 26; and by increasing the length of the first elastic member 17, the extrusion rod 16 can be moved a certain distance in an unloaded state before contacting the workpiece. This distance is used to pressurize the third cavity 25. Therefore, before the extrusion rod 16 contacts the workpiece, the third cavity 25 is in a high-pressure state.

[0058] Then the transfer basket 5 continues to move upward, at which time the transfer basket 5 drives the top rod 29 to disengage from the baffle 30, so the elastic rope 28 pulls the sealing plate 27 to reset and hits the side wall of the third cavity 25, which can drive the workpiece in the transfer basket 5 to vibrate and the small hole is connected to the movable hole, so that the friction between the workpiece and the transfer basket 5 can be reduced through the mutual cooperation of the vibration of the transfer basket 5 and the impact force of the high-pressure airflow discharged from the small hole, which makes it easier for the extrusion rod 16 to straighten the workpiece.

[0059] like Figure 8 As shown, by adopting the above technical solution, the protective sleeve 31 is evenly installed in the installation groove, the protective sleeve 31 is arc-shaped, and the protective sleeve 31 is made of sponge material.

[0060] The air holes away from the workpiece are covered by the protective cover 31, which reduces the exhaust volume of the air holes in contact with the protective cover 31, thereby enhancing the exhaust volume of the exhaust valve 11 blowing air toward the workpiece, thereby improving the cleaning effect of the airflow and the brush 19 on the workpiece; and in the process of contact between the sponge and the brush 19, impurities attached to the surface of the brush 19 will be stuck in the sponge, thereby achieving the effect of automatically cleaning the brush 19, further improving the cleaning effect of the brush 19 on the workpiece.

[0061] A feeding method suitable for the above-mentioned bearing ring processing feeding device comprises the following steps:

[0062] S1, placing the workpiece to be processed in the transfer basket 5, and then starting the driving motor, the driving motor drives the sprocket 2 to rotate, and at this time the chain 3 drives the transfer basket 5 to move along the circular track on the mounting frame 1;

[0063]

[0063] During the movement of the transfer basket 5, the workpiece contacts the roller 9. At this time, both the workpiece and the roller 9 are in a rotating state. The gas in the space below the counterweight 13 in the first cavity 10 is discharged through the exhaust valve 11 and impacts the surface of the workpiece. At the same time, the brush 19 scrapes on the surface of the workpiece;

[0064] When the transfer basket 5 moves to the surface of the magnet 18, the extrusion rod 16 moves towards the magnet 18 and pushes the workpiece. At the same time, the sealing plate 27 impacts the side wall of the third cavity 25 to drive the transfer basket 5 to vibrate, and the small holes exhaust upward to impact the workpiece, so as to straighten the workpiece. The straightened workpiece rolls onto the surface of the guide plate 7;

[0065]

[0064] During the rolling process of the workpiece along the guide plate 7, the upward moving transfer basket 5 drives the movable plate 21 to intermittently squeeze the workpiece on the surface of the guide plate 7 through the push rod 23, and straightens the workpiece at any time.

[0066] Usage method: First, install a driving motor on the annular mounting frame 1, and fix the output end of the driving motor to the rotating shaft of the sprocket 2. Therefore, when the driving motor works, the sprocket 2 in a rotating state can drive the chain 3 to rotate along the annular mounting frame 1. At the same time, the mounting rod 4 and the transfer basket 5 move together with the chain 3, and the workpiece loaded in the transfer basket 5 moves together with the transfer basket 5; Since the bottom wall of the transfer basket 5 is inclined towards the guide plate 7, the workpiece in the transfer basket 5 always has a tendency to roll towards the limiting plate 6, and under the action of the first elastic member 17, the workpiece in the transfer basket 5 is located in the space between the extrusion rod 16 and the limiting plate 6.

[0067] In the process of the transfer basket 5 moving upward along the surface of the limit plate 6, the workpiece in the transfer basket 5 is always in contact with the roller 9 in the installation groove, and the roller 9 can be driven to rotate during the rolling of the workpiece. During the rotation of the roller 9, the counterweight block 13 flips intermittently, thereby driving the diaphragm 12 to bulge downward. When the diaphragm 12 bulges downward, the gas in the space below the diaphragm 12 is discharged through the exhaust valve 11, and the airflow impacts the surface of the workpiece, thereby cleaning the surface of the workpiece. At the same time, the space above the diaphragm 12 is inhaled from the outside through the intake valve 14. When the transfer basket 5 moves to the top of the limit plate 6 and continues to move upward, the extrusion rod 16 is attracted by the magnet 18, and the attraction is greater than the elastic force of the first elastic member 17. At this time, the extrusion rod 16 drives the slider 15 to move along the guide groove and applies a thrust to the workpiece, thereby being able to move the workpiece. The workpiece is pushed to the surface of the magnet 18, and the workpiece is straightened by the pressure of the extrusion rod 16 on the workpiece. After the workpiece is straightened, the transfer basket 5 drives the workpiece to move up along the surface of the magnet 18 with a mirror surface. Finally, when the inner bottom wall of the transfer basket 5 is parallel to the top wall of the guide plate 7, the workpiece will be in a straightened state and roll to the surface of the guide plate 7, and then roll to the designated position along the guide plate 7 for the next processing step. During the entire loading process, the impurities on the surface of the workpiece are cleaned and the workpiece rolled to the surface of the guide plate 7 is straightened by the extrusion rod 16. During the exhaust process of the pores, the gas discharged from the pores impacts the brush 19; because the roller 9 is in a rotating state, the brush 19 that is partially in contact with the outer wall of the workpiece will shake under the impact force of the airflow, and the shaking brush 19 scrapes on the surface of the workpiece, thereby assisting the airflow to clean the surface of the workpiece.

[0068] When the transfer basket 5 is not in contact with the push rod 23, under the action of gravity, the push rod 23 is in a horizontal state, and the push rod 23 is in contact with the bottom end of the side wall of the movable plate 21. During the upward movement of the transfer basket 5, the top wall of the transfer basket 5 is in contact with the push rod 23 and pushes the push rod 23 to rotate upward. During the rotation of the push rod 23, the push rod 23 applies an upward thrust to the inclined surface of the movable plate 21. Since the movable plate 21 can only move in the horizontal direction under the action of the insertion rod 20, as the push rod 23 rotates upward, the movable plate 21 is also pushed by the push rod 23, and the second elastic member 22 is stretched, that is, the movable plates 21 on the two mounting plates 8 are close to each other. At this time, the movable plates 21 close to each other 1 squeezes the workpiece, so that the workpiece can be straightened again; when the transfer basket 5 has not moved to the surface of the magnet 18, under the action of the elastic rope 28, the movable hole on the sealing plate 27 is aligned with the small hole, at this time, the side wall of the sealing plate 27 is in contact with the side wall of the third cavity 25, and the elastic rope 28 is in a stretched state. During the upward movement of the transfer basket 5, when the transfer basket 5 is about to move to the bottom of the magnet 18, the end of the push rod 29 extending from the third cavity 25 contacts the bottom wall of the baffle 30. At this time, under the action of the inclined surface on the push rod 29, the push rod 29 retracts into the third cavity 25 and drives the sealing plate 27 to move, so that the small hole and the movable hole are misaligned, and the transfer basket 5 moves to the bottom of the magnet 18.

[0069] When the extrusion rod 16 moves along the guide groove, the first elastic member 17 is squeezed, and the volume of the second cavity 24 becomes smaller. The gas in the second cavity 24 is discharged into the third cavity 25 through the conduit 26; and by increasing the length of the first elastic member 17, the extrusion rod 16 can be moved a certain distance in an unloaded state before contacting the workpiece. This distance is used to pressurize the third cavity 25. Therefore, before the extrusion rod 16 contacts the workpiece, the third cavity 25 is in a high-pressure state.

[0070] Then the transfer basket 5 continues to move upward, at which time the transfer basket 5 drives the top rod 29 to disengage from the baffle 30, so the elastic rope 28 pulls the sealing plate 27 to reset and hits the side wall of the third cavity 25, at which time the workpiece in the transfer basket 5 can be driven to vibrate and the small hole is connected to the movable hole, so that the friction between the workpiece and the transfer basket 5 can be reduced through the cooperation of the vibration of the transfer basket 5 and the impact force of the high-pressure airflow discharged from the small hole.

[0071] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
