Description

Technical Field

[0001] The present invention relates to the field of stainless steel ball transportation, and particularly to a transportation device for producing rust-proof and corrosion-proof stainless steel balls. Background Art

[0002] As an important component of precision parts such as bearings, the production process of stainless steel small balls is complex and has extremely high requirements. Currently, the production of stainless steel small balls generally includes multiple processes such as cold heading, ball lapping, quenching, tempering, ball grinding, strengthening, primary lapping, cleaning, appearance inspection, fine lapping, pre-cleaning, cleaning, and final inspection and warehousing. Most of these processes are automated on the production line. However, in the quenching stage, the stainless steel small balls need to be collected from the end of the conveyor belt into a frame and then transferred to the quenching equipment for processing.

[0003] In this process, the stainless steel small balls are prone to collision in the collection device at the end of the conveyor belt, resulting in deformation of the small balls or strong scratches on the surface. Such damage will not only affect the dimensional accuracy and surface quality of the stainless steel small balls, but may also seriously affect their service performance as precision parts. Especially in applications such as bearings that require extremely high surface finish and dimensional accuracy, such damage may lead to product failure or a significant reduction in service life. However, the existing transportation devices lack effective protection measures when collecting and transporting stainless steel small balls, and cannot avoid the collision and friction between the small balls.

[0004] Based on the above situation, there is an urgent need for a transportation device for producing rust-proof and corrosion-proof stainless steel balls to reduce the loss and impact of stainless steel small balls during transportation. Summary of the Invention

DETAILED DESCRIPTION

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] Example 1: Refer to the attached Figure 1-3 A conveying device for producing rust-proof and corrosion-resistant stainless steel balls includes a base 11 as a bearing body, an upper surface of which is provided with an inclined surface, a feeder 1 for conveying stainless steel balls is provided on the base 11, a sliding plate 12 is slidably connected to the base 11, a collecting frame 13 is clamped on the sliding plate 12, a receiving rack 17 is connected to the discharge port of the feeder 1, and is inclined with the left side higher and the right side lower, and gravity is used to assist the stainless steel balls to slide smoothly into the collecting frame 13, a double channel is provided in the receiving rack 17 for diversion, to ensure that the stainless steel balls are queued and conveyed in sequence to avoid accumulation and collision, and the outlet of the receiving rack 17 is located above the collecting frame 13, for guiding the stainless steel balls into the collecting frame 13.

[0029] When the stainless steel ball rolls at high speed in the receiving rack 17, since the side walls of the channel are made of rigid material, the stainless steel ball will collide with the side walls, resulting in the following problems: direct collision of the stainless steel ball with the rigid side wall may cause scratches on its surface, affecting its surface quality as a precision component; frequent collisions may cause slight deformation of the stainless steel ball, affecting its dimensional accuracy; the collision of the stainless steel ball with the rigid side wall will generate noise and vibration, affecting the comfort of the working environment and the stability of the equipment.

[0030] In order to reduce the damage of the channel side wall to the stainless steel ball, specifically, the side wall of the channel is provided with a buffer pad 16 for absorbing the impact energy when the stainless steel ball collides with the side wall. The buffer pad 16 is made of a material with good elasticity and wear resistance, such as rubber, polyurethane or silicone. The buffer pad 16 can be pasted, clamped or fixed to the channel side wall by bolts to ensure its firmness and stability.

[0031] Reference appendix Figure 2 When the stainless steel balls enter the collection box 13 from the material receiving rack 17, due to the height difference between the outlet and the bottom wall, the stainless steel balls will collide under the action of their own gravitational acceleration, resulting in deformation of the balls or strong scratches on the surface, affecting the dimensional accuracy of the precision parts. Therefore, in this embodiment, when the stainless steel balls enter the collection box 13 from the material receiving rack 17, it is necessary to buffer them to absorb their impact energy and reduce collisions and damage.

[0032] Specifically, a support 110 is connected to the outlet of the material receiving rack 17. A low-speed motor 19 is installed on the support 110. The output shaft of the low-speed motor 19 is connected to a telescopic rod 18 through a coupling. The telescopic end of the telescopic rod 18 is connected to an inner buffer net 141 for absorbing the impact energy of the stainless steel balls. The outside of the inner buffer net 141 is connected to a connector 15, and an outer buffer net 14 is connected to the connector 15 for further absorbing the impact energy. The inner buffer net 141 is arranged in a pentagonal pyramid shape, and the outer buffer net 14 is arranged in an octagonal prism shape, and the outer buffer net 14 is located outside the inner buffer net 141.

[0033] When the stainless steel balls fall from the outlet of the material receiving rack 17, they first hit the outer wall of the pentagonal pyramid-shaped inner buffer net 141, causing the first bounce, absorbing part of the impact energy, and reducing the speed of the stainless steel balls. Then, the stainless steel balls bounce from the inner buffer net 141 to the inner wall of the outer buffer net 14 and then bounce back to the outer wall of the inner buffer net 141. After multiple bounces, the impact energy is gradually absorbed and its potential energy is reduced. Finally, the stainless steel balls will fall into the collection box 13 through the gap between the inner buffer net 141 and the outer buffer net 14. At this time, its impact force has been greatly reduced. Therefore, when the stainless steel balls fall into the collection box 13, the collision force is very small and will not damage the surface of the stainless steel balls.

[0034] Since the bearing platform 11 is inclined, the collection box 13 placed on it is also inclined. When the stainless steel balls fall into the collection box 13, they will slide to the right along the bottom wall of the collection box 13. Because the collection box 13 is inclined, the stainless steel balls will preferentially fill the right part of the collection box 13. As the stainless steel balls continue to fall, the right part of the collection box 13 is gradually filled first, and then expands to the left part. This distribution method avoids local accumulation of stainless steel balls in the collection box 13 and ensures uniform collection.

[0035] When multiple stainless steel balls are conveyed from the receiving rack 17 in sequence, in order to prevent the latter stainless steel ball from hitting the former one, the low-speed motor 19 can be controlled to drive the retractable rod 18 to rotate, thereby driving the inner buffer net 141, the connecting piece 15, and the outer buffer net 14 to rotate together. During the rotation process, the stainless steel balls will hit different surfaces of the inner buffer net 141, preventing all stainless steel balls from hitting the same position, thus further reducing collisions and damages.

[0036] Reference appendix Figure 3 , when the stainless steel balls are queued and conveyed on the receiving rack 17 in sequence, the stainless steel ball at the rear will give a thrust to the stainless steel ball in front of it, thereby accelerating its rolling speed. Therefore, when the stainless steel balls roll out from the outlet of the receiving rack 17, it is necessary to reduce their rolling speed to avoid buffer failure caused by excessive acceleration.

[0037] Specifically, a receiving plate 111 is connected to the outlet of the receiving rack 17 for guiding the rolling direction of the stainless steel balls. A rubber pad 112 is provided on the upper surface of the receiving plate 111 for increasing the friction with the stainless steel balls, thereby reducing their rolling speed.

[0038] When the stainless steel balls roll out from the receiving rack 17, they will fall on the rubber pad 112 on the upper surface of the receiving plate 111. Due to the surface characteristics of the rubber pad 112, the friction between the stainless steel balls and the rubber pad 112 increases, thereby reducing the rolling acceleration of the stainless steel balls. By controlling the magnitude of the friction, the rolling speed of the stainless steel balls can be reduced to an appropriate range to ensure that they can roll onto the outer wall of the inner buffer net 141 at a controllable speed. In this way, the stainless steel balls will not deviate from the target position due to excessive speed, avoiding buffer failure caused by parabolic motion.

[0039] In this embodiment, through the buffer system composed of the inner buffer net 141 and the outer buffer net 14, the stainless steel balls bounce multiple times during the falling process, gradually absorbing the impact energy and reducing their potential energy. Finally, they enter the collection frame 13 with a smaller impact force, avoiding deformation or surface scratches caused by collisions; through the cooperation of the deceleration device and the buffer system, the stainless steel balls can enter the collection frame 13 at a controllable speed and direction, avoiding deviation from the target position caused by high-speed rolling or parabolic motion.

[0040] Reference appendix Figure 4-6As the number of stainless steel balls in the collection frame 13 gradually increases, the stainless steel balls will accumulate and gradually submerge the buffer device. After the buffer device is submerged by the stainless steel balls, it cannot effectively absorb the impact energy of the stainless steel balls, causing the stainless steel balls to collide when entering the collection frame 13, which may cause deformation or surface scratches, affecting the dimensional accuracy and surface quality of the precision component. Therefore, this embodiment needs to design a mechanical structure that can make the buffer device rise synchronously with the increase of the stainless steel ball loading amount, ensuring that the buffer device is always located above the accumulation surface of the stainless steel balls.

[0041] Specifically, the material receiving rack 17 is connected with a symmetrically distributed positioning piece 27 near the outlet, and a first connecting plate 2 is fixedly connected to the inner buffer net 141, and a bidirectional screw 22 is fixedly connected to the bottom of the first connecting plate 2, and the end of the bidirectional screw 22 is rotatably connected to a connecting rack 25, and a symmetrically distributed guide rod 21 is fixed to the connecting rack 25, and the bidirectional screw 22 slides on the symmetrically distributed guide rod 21, and a symmetrically distributed support plate 24 is rotatably connected to the connecting rack 25, and a second connecting plate 23 is threadedly connected to the bidirectional screw 22, and the second connecting plate 23 consists of a short plate with an internal thread and two long plates, and the two long plates are located on both sides of the short plate, and each long plate is connected to the short plate by rotation, and the long plate is rotatably connected to the adjacent support plate 24, and a sliding piece 26 is connected to the connecting rack 25, and the sliding piece 26 slides up and down between the symmetrically distributed positioning pieces 27.

[0042] As mentioned above, when the receiving rack 17 drives the inner buffer net 141, the connecting piece 15, and the outer buffer net 14 to rotate together through the retracting rod 18, the first connecting plate 2 rotates together with the inner buffer net 141, thereby driving the bidirectional screw 22 to rotate, and then driving the second connecting plate 23 to reciprocate up and down. When the second connecting plate 23 moves upward, it drives the support plate 24 to flip upward. When the second connecting plate 23 moves downward, the support plate 24 flips downward and resets. When the support plate 24 flips upward, if a stainless steel ball falls directly below the support plate 24, the support plate 24 will contact the stainless steel ball. As the support plate 24 flips downward, the stainless steel ball will be cushioned under the support plate 24, and the support plate 24 will be supported on the stainless steel ball, thereby pushing the support plate 24 to move upward, and then transmitted to the sliding piece 26 through the connecting rack 25. The sliding piece 26 slides upward between the symmetrically distributed positioning pieces 27, driving the buffer device to rise as a whole to avoid being submerged, and causing the retracting rod 18 to shrink upward to ensure that the buffer function is always effective.

[0043] A lifting member 28 is rotatably connected to the telescopic end of the telescopic rod 18. A pair of symmetrically distributed clamping members 281 are slidably connected to the lifting member 28. A pair of energy storage springs 29 are connected between the symmetrically distributed clamping members 281 and the lifting member 28 respectively. The symmetrically distributed energy storage springs 29 are wound around the adjacent clamping members 281 respectively. One side of the clamping member 281 close to the positioning member 27 is provided with an inclined surface. A plurality of uniformly distributed jacks are formed in the symmetrically distributed positioning members 27. The lifting member 28 is clamped and matched with the positioning member 27 through the clamping members 281 and the jacks.

[0044] When the buffer device moves upward as a whole, during the process of the telescopic rod 18 contracting upward, the lifting member 28 will drive the clamping member 281 to move upward accordingly. During the upward movement of the clamping member 281, the positioning member 27 will abut against the inclined surface of the clamping member 281, forcing the clamping member 281 to withdraw from the lower jack. At this time, the energy storage spring 29 deforms and stores elastic potential energy. When the clamping member 281 continues to move upward and aligns with the upper jack, the elastic force of the energy storage spring 29 is released, pushing the clamping member 281 into the upper jack to achieve clamping and matching, ensuring stable locking after each upward movement. As the filling amount of stainless steel balls in the collection box 13 increases, the buffer device will move upward synchronously and quantitatively, and the height of each upward movement is determined by the spacing between the jacks.

[0045] When the collection box 13 filled with stainless steel balls is transported to the quenching equipment for processing, an empty collection box 13 needs to be placed on the sliding plate 12. At this time, the buffer device needs to move downward to reset. The specific operation is as follows: Withdraw the clamping member 281 from the jack of the positioning member 27 to release the clamping and matching between the clamping member 281 and the jack. Under the action of the self-gravity of the buffer device and components such as the support plate 24, the sliding member 26, and the connecting frame 25, the device moves downward as a whole to reset. After releasing the clamping member 281, under the elastic force of the energy storage spring 29, the clamping member 281 will automatically insert into the lower jack to re-achieve clamping and matching, ensuring stable locking of the device.

[0046] Thus, through the clamping and matching between the clamping member 281 and the jack, the rising height of the buffer device can be accurately controlled, avoiding device failure caused by excessive or insufficient movement. The downward reset process is also accurately controllable, ensuring that the device can quickly return to the initial position. After each upward or downward movement, the clamping and matching between the clamping member 281 and the jack ensure stable locking of the device, preventing accidental displacement caused by external impact or vibration, avoiding excessive movement or unnecessary friction of the device, reducing wear of components, and extending the service life of the device.

[0047] Refer to the appendix Figure 6, when the stainless steel balls fall into the collection box 13, the landing points of the stainless steel balls are uncontrollable. Therefore, it may cause an excessive amount of balls in a local area of the collection box 13 while insufficient balls in other places. In particular, the amount of balls under the two support plates 24 is different, causing the downwardly deflected support plate 24 not to support on the spherical surface at the same height, resulting in the inability of the buffer device to move upward synchronously and increasing the risk of being submerged. Therefore, in this embodiment, a mechanism for driving the collection box 13 to reciprocate back and forth is required to make the distribution of the stainless steel balls in the collection box 13 uniform.

[0048] Specifically, a servo motor 212 is installed on the bearing platform 11, and its output shaft is connected to an eccentric wheel 2121 through a coupling for power transmission. The bearing platform 11 is connected to a limiting plate 211, and a pushing member 213 is slidably connected to the limiting plate 211. One end of the pushing member 213 is provided with an oval ring that is sleeved on the eccentric wheel 2121, and the other end is connected to the sliding disk 12, which can convert the rotational motion of the eccentric wheel 2121 into the reciprocating back-and-forth movement of the sliding disk 12.

[0049] When a certain amount of stainless steel balls fall into the collection box 13, the servo motor 212 can be controlled to drive the eccentric wheel 2121 to rotate. The rotational motion of the eccentric wheel 2121 is converted into the reciprocating back-and-forth movement of the sliding disk 12 through the oval ring of the pushing member 213. The sliding disk 12 drives the collection box 13 to reciprocate back and forth together, making the stainless steel balls in the collection box 13 evenly distributed under the action of inertia.

[0050] Symmetrically distributed rollers 210 are provided at the bottom of the sliding disk 12 to support the sliding disk 12 and reduce friction. When the sliding disk 12 makes a reciprocating back-and-forth movement, the rollers 210 roll back and forth accordingly, keeping the sliding disk 12 balanced during the movement and avoiding tilting or jamming caused by uneven force, thus improving the stability of the overall operation.

[0051] Embodiment 2: Refer to the appendix Figure 7-8 , when the number of stainless steel balls in the collection box 13 reaches a certain amount, the stainless steel needs to be transferred to the quenching equipment for processing. At this time, it is necessary to suspend the feeding of stainless steel balls from the receiving rack 17 into the collection box 13. Specifically, a guide plate 33 is provided on the buffer pad 16, and L-shaped baffles 36 are slidably connected between the guide plates 33 in the same channel. Connecting columns 34 are connected to the tops of the L-shaped baffles 36.

[0052] When it is necessary to pause feeding into the collection frame 13, the connecting column 34 is manually moved downward, driving the L-shaped baffle 36 to slide downward, sealing the channel of the receiving rack 17, and the stainless steel ball is blocked by the L-shaped baffle 36 and cannot continue to enter the collection frame 13. When the empty collection frame 13 is placed on the sliding plate 12, it is necessary to restart feeding, and the connecting column 34 is manually pulled upward to drive the L-shaped baffle 36 to slide upward, unblocking the channel of the receiving rack 17, and the stainless steel ball continues to fall into the empty collection frame 13 along the receiving rack 17.

[0053] Since the above-mentioned control requires manual intervention, the operating efficiency is low. Especially in high-frequency operation scenarios, workers are required to always pay attention to the number of stainless steel balls in the collection frame 13 and operate the connecting column 34 in time, which increases the labor cost. The accuracy of manual control is limited, which may cause the channel to open and close untimely or incompletely. Therefore, this embodiment needs to automatically seal the channel of the material receiving rack 17 when the number of stainless steel balls in the collection frame 13 gradually increases, and reopen the channel after the empty collection frame 13 is placed.

[0054] Specifically, a second rack 32 is slidably connected between the two connecting columns 34, and a telescopic spring 35 is connected between the second rack 32 and each L-shaped baffle 36. Each telescopic spring 35 is wound around an adjacent connecting column 34. A symmetrically distributed first rack 3 is connected to the sliding member 26 and moves with the up and down movement of the sliding member 26. A symmetrically distributed gear 31 is rotatably connected to the material receiving rack 17 and meshes with the first rack 3 and the second rack 32 for transmitting power.

[0055] When the number of stainless steel balls in the collecting frame 13 gradually increases, the sliding member 26 continues to move upward, driving the first rack 3 to move upward, thereby driving the second rack 32 to move downward through the gear 31, and then driving the connecting column 34 and the L-shaped baffle 36 to move downward. The L-shaped baffle 36 automatically blocks the channel of the material receiving rack 17 and stops guiding the stainless steel balls into the collecting frame 13. The telescopic spring 35 is slightly deformed during the downward movement of the L-shaped baffle 36 to store elastic potential energy. When the empty collecting frame 13 is placed on the sliding plate 12, the sliding member 26 moves downward, driving the second rack 32 to move upward through the gear 31, and driving the connecting column 34 and the L-shaped baffle 36 to move upward, releasing the blockage of the channel, and the stainless steel balls continue to fall into the empty collecting frame 13 along the material receiving rack 17.

[0056] This embodiment realizes automatic opening and closing control of the channel through the gear 31 transmission member, and can automatically block the channel of the material receiving rack 17 when the number of stainless steel balls in the collection frame 13 reaches a certain amount, and reopen the channel after the empty collection frame 13 is placed, without the need for manual intervention, thereby improving efficiency and reducing labor costs.

[0057] The above embodiments are only used to illustrate the technical concept and features of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It is not intended to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
