Description

Technical Field

[0001] This utility model relates to the field of bearing processing equipment technology, specifically to an ultra-miniature bearing ring oil pipe conveying structure. Background Technology

[0002] In automated production lines for bearing rings, especially for ultra-miniature bearing rings, the automated transfer of rings between various processing units (such as grinding machines and ultra-precision machines) is a key link in ensuring production efficiency and process continuity.

[0003] Currently, the industry widely adopts pneumatic conveying to achieve rapid transfer of bearing rings. This conveying method typically uses compressed air as power to make the bearing rings move at high speed in the conveying pipeline.

[0004] However, this traditional gas-transport-based structure has a series of inherent drawbacks that are difficult to overcome in practical applications, especially when dealing with ultra-miniature, high-precision, and thin-walled bearing rings: 1. High operational instability, prone to material jamming: Compressed air itself is compressible, and its flow rate and pressure are easily affected by pipeline fluctuations, resulting in pulsating conveying power that is difficult to maintain constant. For ultra-lightweight micro rings, this unstable power can easily cause them to become disordered, stagnant, or even blocked at the conveying pipeline or reversing interface, i.e., "material jamming". Secondly, the ring will generate significant static and dynamic friction between itself and the dry inner wall of the pipe. During the startup phase, a large airflow pressure is required to overcome the static friction. Once started, the ring may bounce and roll at high speed inside the pipe due to power overshoot, and after multiple collisions with the pipe wall, it may get stuck in narrow or bend areas.

[0005] 2. Causes damage to the surface quality of the bearing rings: In pursuit of conveying efficiency, pneumatic conveying often results in the bearings achieving a high initial velocity. During high-speed movement, the ultra-micro bearings will experience intense random collisions and friction with the hard inner wall of the metal pipe, generating numerous microscopic dents, scratches, and indentations. Utility Model Content

[0006] To address the technical problems existing in the background art, this utility model proposes an ultra-miniature bearing ring oil pipe delivery structure.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: An ultra-miniature bearing ring oil pipe conveying structure includes a conveying line, on which a ring feeding assembly and a ring discharging assembly are provided; The bearing ring feeding assembly includes a receiving seat, a discharge pipe inserted on the receiving seat, a feeding oil pipe connected to the discharge pipe, and a pushing unit for pushing the material. The receiving seat has a discharge groove. The actuating end of the pushing unit is connected to a push rod. The pushing unit drives the push rod to move and moves the bearing ring in the discharge groove to the conveyor line. A magnetic suction unit is embedded in the discharge groove. The magnetic suction unit is arranged opposite to the output end of the discharge pipe. The bearing ring discharge assembly includes a discharge channel and a discharge unit for discharging materials. The discharge unit has a discharge block connected to its actuating end. The discharge unit drives the discharge block to move and pushes the bearing ring on the conveyor line into the discharge channel.

[0008] Preferably, an installation groove is formed on the discharge trough, and the magnetic suction unit is embedded in the installation groove. Through the above improvements, the installation groove and the magnetic suction unit are used to cooperate to ensure the stability of the installation of the magnetic suction unit.

[0009] Preferably, the magnetic suction unit has an oil drain hole, and the mounting groove has a connecting hole that communicates with the oil drain hole. With the above improvements, during the conveying process of the bearing ring, the oil can be discharged through the oil drain hole and the connecting hole, and the oil can be finally returned to the oil tank or recycling system of the main conveying line, forming a complete oil discharge path and avoiding the problems of oil blockage and poor oil discharge.

[0010] Preferably, the discharge trough has a number of oil drain holes arranged at intervals. Through the above improvements, excess oil can be quickly drained away, preventing the oil level from being too high and generating eddies, ensuring accurate positioning of the collar, and effectively eliminating the oil film adsorption effect between the collar and the bottom of the trough, greatly reducing the pushing resistance and starting viscosity, and making the pushing action more stable and accurate.

[0011] Preferably, an oil drain groove is formed on the push rod. Through the above improvements, the fluid resistance and adhesion problems of the push rod moving in the oil are effectively solved. The oil drain groove provides a flow channel for the oil and improves the oil return efficiency.

[0012] Preferably, an oil collection frame is provided below the conveyor line, and an oil collection tray connected to the oil collection frame is connected to the oil collection frame. The oil collection tray is inclined and located below the receiving seat. Through the above improvements, by adding an inclined oil collection tray and oil collection frame, a highly efficient oil recovery system is constructed. It can collect and centrally guide back all the oil splashed from the oil drain hole of the receiving seat, the transfer of the ring, and the oil that drips naturally from the conveyor line, greatly reducing oil leakage and waste, maintaining the cleanliness and hygiene of the equipment and working environment, and realizing the recycling of lubricating oil, effectively reducing production and operating costs.

[0013] Preferably, the discharge channel is equipped with a demagnetizing unit. Through the above improvements, the residual magnetism of the bearing rings due to the previous magnetic positioning is eliminated, and multiple bearing rings are prevented from interfering with automatic assembly due to mutual magnetic attraction. This ensures the final cleanliness and assembly accuracy of the bearing and improves the product qualification rate.

[0014] Preferably, a drying air pipe is provided on the discharge channel, and the drying air pipe is positioned towards the bearing ring. Through the above improvement, by setting a drying air pipe facing the bearing ring in the discharge channel, clean compressed air is used to blow away most of the oil adhering to the surface of the bearing ring before it enters the next key process (such as assembly or testing), which significantly reduces the amount of oil carried by the bearing ring, reduces pollution to subsequent equipment, and improves production continuity and efficiency.

[0015] Preferably, the conveyor line is provided with a connecting plate connecting the bearing ring feeding assembly and the bearing ring discharging assembly. The connecting plate forms a conveying channel for the movement of the bearing ring, and the input end of the conveying channel is provided with a guide slope. Through the above improvements, the connecting plate with the guide slope on the conveyor line provides a smooth transition for the transfer of the bearing ring between the feeding and discharging assemblies. The conveying channel can effectively constrain the movement trajectory of the bearing ring and prevent deviation. The guide slope at the inlet can guide the bearing ring to enter smoothly and avoid jamming, squeezing or overturning caused by slight misalignment, which greatly improves the reliability and efficiency of the conveying.

[0016] Preferably, a pusher sensor is installed on the conveying channel. With the above improvements, the pusher sensor is installed on the conveying channel to monitor the position status of the ring in real time. It can accurately detect whether the pusher is successful, whether the ring is in place or whether there is a blockage, and feed the signal back to the control system to realize intelligent linkage with the pusher and discharge units. This effectively prevents the equipment from running idle and malfunctioning due to jamming or missed push, and greatly improves the degree of automation and operational reliability.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects: The bearing rings are fed into the discharge pipe via the feeding oil pipe and then into the discharge chute. Once the bearing rings are in the discharge chute, the magnetic suction unit attracts them, preventing them from tilting during the discharge process. A push rod then pushes the bearing rings onto the conveyor line, where they are transported to the designated position and discharged through the discharge channel by the discharge block. Compared to pneumatic conveying, oil conveying technology fundamentally eliminates the risk of bearing ring rust. With its excellent buffering and lubrication properties, it virtually eliminates bumps and scratches during transport. Furthermore, the oil also provides heat dissipation and pre-lubrication, and the system operates smoothly and quietly, significantly improving product yield and the workshop environment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0021] like Figure 1-7 As shown, an ultra-miniature bearing ring oil pipe conveying structure includes a conveying line 1, on which a ring feeding assembly 2 and a ring discharging assembly 3 are provided.

[0022] Specifically, the bearing ring feeding assembly 2 includes a receiving seat 1.1, a dropping pipe 1.2 inserted on the receiving seat 1.1, a feeding oil pipe 1.3 connected to the dropping pipe 1.2, and a pushing unit 1.4 for pushing the material. A discharge groove 1.5 is formed on the receiving seat 1.1. The actuating end of the pushing unit 1.4 is connected to a push rod 1.6. The pushing unit 1.4 drives the push rod 1.6 to move and moves the bearing ring in the discharge groove 1.5 to the conveyor line 1. The discharge groove 1.5 is embedded with a magnetic suction unit, which is arranged opposite to the output end of the dropping pipe 1.2.

[0023] Furthermore, the bearing ring discharge assembly 3 includes a discharge channel 2.1 and a discharge unit 2.2 for discharging materials. The discharge unit 2.2 is connected to a discharge block 2.3 on its actuating end. The discharge unit 2.2 drives the discharge block 2.3 to move and pushes the bearing ring on the conveyor line 1 into the discharge channel 2.1.

[0024] During the bearing manufacturing process, the finished bearing rings are fed into the discharge pipe 1.2 via the feeding oil pipe 1.3, and then into the discharge trough 1.5. When the bearing rings are placed in the discharge trough 1.5, the magnetic suction unit attracts the bearing rings to prevent them from tilting during the discharge process. Then, the push rod 1.6 pushes the bearing rings onto the conveyor line 1. Under the action of the conveyor line 1, the bearing rings are transported to the designated position and then enter the discharge channel 2.1 for discharge under the action of the discharge block 2.3. Compared with pneumatic conveying, oil conveying technology fundamentally eliminates the risk of rust on the bearing rings. With its excellent buffering and lubrication characteristics, it almost eliminates bumps and scratches during the conveying process. At the same time, the oil also has the functions of heat dissipation and pre-lubrication. The system operates smoothly and with low noise, which significantly improves the product yield and the workshop environment.

[0025] As a further explanation of the embodiment of the docking base 1.1, an installation groove 3.1 is formed on the discharge groove 1.5, and the magnetic suction unit is embedded in the installation groove 3.1. The installation groove 3.1 cooperates with the magnetic suction unit to ensure the stability of the installation of the magnetic suction unit.

[0026] Preferably, a transparent plastic cover can be installed on the discharge chute 1.5 to prevent the bearing rings from flipping during the material pushing process.

[0027] like Figure 1 , Figure 2As shown, further explanation of the conveying oil recovery in this example: an oil collection frame 4.1 is provided below the conveyor line 1, and an oil collection tray 4.2 connected to the oil collection frame 4.1 is connected to the oil collection frame 4.1. The oil collection tray 4.2 is set at an angle and is located below the receiving seat 1.1. By adding the inclined oil collection tray 4.2 and the oil collection frame 4.1, a highly efficient oil recovery system is constructed. It can collect all the oil from the oil drain hole 3.4 of the receiving seat 1.1, the oil splashed during the transfer of the ring, and the oil that drips naturally from the conveyor line 1 and guide it back in a centralized manner. This greatly reduces oil leakage and waste, keeps the equipment and working environment clean and hygienic, and realizes the recycling of lubricating oil, effectively reducing production and operating costs.

[0028] Furthermore, the magnetic suction unit is arranged in a ring shape, forming an oil drain hole 3.2 on the magnetic suction unit, and a connecting hole 3.3 connected to the oil drain hole 3.2 is formed in the mounting groove 3.1. During the conveying process of the bearing ring, the oil can be discharged through the oil drain hole 3.2 and the connecting hole 3.3, and the oil can be finally led back to the oil tank or recovery system of the main conveying line 1, forming a complete oil discharge path and avoiding the problems of oil circuit blockage and poor oil discharge.

[0029] Because the bearing rings are hollow, the oil drain hole 3.2 does not affect the adsorption of the bearing rings, and the oil inside the bearing rings can be better recovered.

[0030] In addition, the discharge trough 1.5 has several oil drain holes 3.4 arranged at intervals, which can quickly guide away excess oil, prevent the oil level from being too high and generating eddies, ensure accurate positioning of the collar, and effectively eliminate the oil film adsorption effect between the collar and the bottom of the trough, greatly reducing the pushing resistance and starting stickiness, making the pushing action more stable and accurate.

[0031] Preferably, the push rod 1.6 has an oil drain groove 3.5, which effectively solves the fluid resistance and adhesion problems of the push rod 1.6 moving in the oil. The oil drain groove 3.5 provides a guide channel for the oil and improves the oil return efficiency.

[0032] like Figure 1 , Figure 2 , Figure 6 As shown, as a further explanation of the connection between the bearing ring feeding assembly 2 and the bearing ring discharging assembly 3, the conveyor line 1 is provided with a connecting plate 6.1 that connects the bearing ring feeding assembly 2 and the bearing ring discharging assembly 3. The connecting plate 6.1 has a conveying channel 6.2 for the movement of the bearing ring, and the input end of the conveying channel 6.2 is provided with a guide slope 6.3.

[0033] A connecting plate 6.1 with a guide ramp 6.3 is installed on the conveyor line 1 to provide a smooth transition for the transfer of the ring between the feeding and discharging components. Its conveying channel 6.2 can effectively constrain the movement trajectory of the ring and prevent it from deviating. The guide ramp 6.3 at the inlet can guide the ring to enter smoothly and avoid jamming, squeezing or overturning caused by slight misalignment, which greatly improves the reliability and efficiency of the conveying.

[0034] Furthermore, a pusher sensor 6.4 is installed on the conveying channel 6.2 to monitor the position status of the ring in real time. It can accurately detect whether the pusher is successful, whether the ring is in place or if there is a blockage, and feed the signal back to the control system to realize intelligent linkage with the pusher and discharge unit 2.2. This effectively prevents the equipment from running idle and malfunctioning due to jamming or missed push, and greatly improves the degree of automation and operational reliability.

[0035] like Figure 2 , Figure 7 As shown, a further explanation of the bearing ring discharge implementation method is provided: the discharge channel 2.1 is equipped with a demagnetizing unit 5.1, which eliminates the residual magnetism of the rings due to the previous magnetic positioning, and prevents multiple rings from interfering with automatic assembly due to mutual magnetic attraction, thereby ensuring the final cleanliness and assembly accuracy of the bearing and improving the product qualification rate.

[0036] The working principle of the demagnetizing unit 5.1 is as follows: an alternating magnetic field with gradually decreasing intensity and constantly changing direction is applied to the magnetized object to disrupt the arrangement of its internal magnetic domains, so that the overall magnetism cancels each other out, thereby achieving the purpose of demagnetization. This is existing technology and will not be described in detail.

[0037] like Figure 7 As shown, in some other embodiments, a drying air pipe 5.2 is provided on the discharge channel 2.1, facing the bearing ring. Clean compressed air is used to blow away most of the oil adhering to the surface of the bearing ring before it enters the next critical process (such as assembly or testing), significantly reducing the amount of oil carried by the bearing ring, reducing contamination of subsequent equipment, and improving production continuity and efficiency. This specific embodiment is merely an explanation of the present invention and is not intended to limit it. Those skilled in the art can make modifications to this embodiment without contributing any inventive step after reading this specification, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.
