Description

Technical Field

[0001] This utility model relates to the field of bearing production equipment technology, and in particular to a nuclear energy rotary bearing buffer rack. Background Technology

[0002] On automated production lines for nuclear slewing bearings, the processing times for each step often vary. To ensure the continuity and coordination of the production process and to avoid disruptions to the overall production cycle due to the long processing time of a particular step, buffer stations are typically set up before time-consuming steps to temporarily store semi-finished workpieces transported from upstream steps.

[0003] Currently, common buffering methods mainly include conveyor line buffering and fixed buffer racks. Conveyor line buffering creates a material buffer zone by extending the length of the conveyor line. While this method enables continuous conveying, it significantly increases the overall layout area of ​​the production line, resulting in low space utilization efficiency. Furthermore, its buffering capacity is usually limited by the conveyor line length. Another method is to use fixed buffer racks, where workpieces are loaded and unloaded using overhead cranes or forklifts. However, these racks have a single function and often fail to implement "first-in, first-out" (FIFO) material management. This can lead to earlier-entering workpieces being held back by later-entering workpieces for extended periods, unable to be prioritized for removal and transfer to the next process. This disrupts the production sequence, hinders refined production management, and may even affect the overall quality traceability of the workpieces.

[0004] Therefore, there is an urgent need in this field for a buffer device that can effectively save floor space and improve space utilization, while ensuring that materials are automatically transferred in strict accordance with the "first-in, first-out" principle, in order to solve the above-mentioned problems in the existing technology. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a nuclear energy rotary bearing buffer rack.

[0006] To achieve the above objectives, this utility model provides a nuclear slewing bearing buffer rack, including a frame, several feeding channels arranged at an inclined position at the top of the frame, and several unloading channels arranged at an inclined position at the bottom of the frame. Both the feeding and unloading channels include material channel structures for supporting the bearings. Its innovation lies in that it further includes: The height-adjustable base can move between the loading station and the unloading station via a lifting device mounted on the frame. A buffer channel assembly includes a rotating rod and several buffer channels arranged side by side on the rotating rod, the rotating rod being rotatably mounted on a base; The swing device, mounted on the base and connected to the rotating rod, is used to drive the buffer channel to tilt upward towards the channel when loading and downward towards the channel when unloading. The blocking mechanism is located at the junction of the feeding channel and the buffer channel to control the nuclear energy rotary bearing to enter a single buffer channel at a time. Specifically, when the base is located at the loading station and the buffer channel is inclined to the upward channel, the inlet of the buffer channel is aligned with the outlet of the loading channel to receive the nuclear energy rotary bearing; when the base is located at the unloading station and the buffer channel is inclined to the downward channel, the outlet of the buffer channel is aligned with the inlet of the unloading channel to deliver the nuclear energy rotary bearing.

[0007] Furthermore, the aforementioned lifting device includes a lifting cylinder and a slide rail assembly. The slide rail assembly includes a vertical slide rail mounted on the frame, and sliders that cooperate with the slide rail are provided at both ends of the base. The lifting cylinder is fixed on the frame, and its output end is connected to the base.

[0008] Furthermore, the aforementioned swing device includes a swing cylinder and an extension plate. The extension plate is fixed to the rotating rod, and a fixed plate is provided on the base. The cylinder body of the swing cylinder is hinged to the fixed plate, and its output end is hinged to the extension plate.

[0009] Furthermore, the aforementioned blocking mechanism includes a fixed rod, a stop block, and a blocking cylinder. The fixed rod is fixed to the frame, the stop block is rotatably mounted at the junction of the feed channel and the buffer channel via a rotating shaft, and the cylinder body of the blocking cylinder is hinged to the fixed rod. Its output end is connected to the rotating shaft via a connecting plate to drive the stop block to lift or lower.

[0010] Furthermore, the aforementioned material channel structure includes two parallel side plates and a support plate disposed at the bottom of the side plates, the side plates and the support plate together forming an L-shaped support structure.

[0011] Furthermore, the aforementioned feeding channel is inclined downwards along its feeding direction, and the unloading channel is also inclined downwards along its feeding direction.

[0012] Furthermore, the contact portion between the aforementioned buffer duct and the nuclear energy rotary bearing is made of nylon.

[0013] The beneficial effects of this utility model are: 1. Strict first-in, first-out (FIFO) management is achieved, ensuring production sequence. This invention precisely controls the order in which each nuclear energy rotary bearing enters and leaves the buffer area through the coordinated operation of a lifting device, a swinging device, and a blocking mechanism. Specifically, bearings enter the buffer channel one by one in sequence, and after switching stations via lifting, they are released one by one into the unloading channel in the same order, thus ensuring that the bearings that enter the buffer area first are always removed first and flow into the next process. This effectively solves the problems of workpiece accumulation and sequence disorder that may be caused by traditional fixed material racks, providing a reliable guarantee for refined production management and quality traceability.

[0014] 2. Compact structure, significantly improving space utilization. This utility model adopts a vertical spatial layout, arranging the feeding channel, the liftable buffer channel assembly, and the unloading channel three-dimensionally on the frame. The material receiving and transfer are completed by switching between different workstations through the lifting movement of the buffer channel assembly. This design makes full use of space in the vertical direction, enabling the buffer rack to achieve a buffer capacity comparable to or even greater than that of a long-distance conveyor line while occupying a very small floor area, greatly saving production line layout space.

[0018] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1 to 3 This utility model provides a nuclear energy slewing bearing buffer rack. Its core purpose is to serve as a compact buffer module in the automated production line of nuclear energy slewing bearings, realizing the first-in-first-out automated buffering and transfer of bearing rings, so as to balance the production line cycle and improve space utilization.

[0020] Overall Structure Explanation like Figure 1 As shown, the buffer rack includes a stable frame 1, serving as the foundation support for the entire equipment. A loading station is located at the top of the frame 1, on which several parallel loading channels 2 are installed. A unloading station is located at the bottom of the frame 1, also on which several parallel unloading channels 3 are installed. Both the loading channels 2 and the unloading channels 3 are designed to be inclined, so that the nuclear energy rotary bearing placed within them can automatically roll along the channels under its own gravity.

[0021] In addition to the aforementioned fixed material channel, the core functional components of this utility model also include: a liftable base 52, a buffer material channel assembly 4 mounted on the base 52, a swing device 6 for driving the buffer material channel assembly 4 to swing, and a blocking mechanism 7 located at the outlet of the upper material channel 2.

[0022] Detailed structure of each component 1. Material channel structure: As defined in this utility model, and as Figure 1 and Figure 3 As shown, the feeding channel 2, the unloading channel 3, and the buffer channel 41, which will be described later, all adopt the same channel structure. This structure includes two parallel side plates 21 and a support plate 23 fixed to the bottom of the side plates 21. The side plates 21 and the support plate 23 together form an L-shaped support structure. The bearing rings are confined between the two side plates 21 and roll on the support plate 23. The feeding channel 2, along its feeding direction (from...) Figure 1 From a visual perspective, it is usually tilted downwards from left to right, while the tilt direction of the feed channel 3 is opposite to that, ensuring that the bearing can roll by gravity from different directions.

[0023] 2. Lifting device and buffer material channel assembly: As defined in this utility model, and in conjunction with Figure 2 As shown, the lifting device 5 mainly consists of a lifting cylinder 51 and a slide rail assembly 53. The slide rail assembly 53 includes a vertical slide rail 531 fixed to the frame 1. Sliding blocks 532 that cooperate with the vertical slide rail 531 are installed at both ends of the base 52. The cylinder body of the lifting cylinder 51 is fixed to the frame 1, and its piston rod output end is connected to the base 52. Through the extension and retraction of the lifting cylinder 51, the base 52 can be driven to move precisely between the loading station (high position) and the unloading station (low position) along the slide rail 531.

[0024] The buffer channel assembly 4 is mounted on the base 52. As defined in this invention, the assembly includes a rotating rod 42 and several buffer channels 41 fixed side by side on the rotating rod 42. The rotating rod 42 is rotatably mounted on the base 52 via a bearing seat (not shown in the figure, which is conventional technology), so that all the buffer channels 41 can swing synchronously.

[0025] 3. Swinging device: As defined in this utility model, and in conjunction with Figure 2As shown, the swing device 6 is used to control the tilt angle of the buffer material channel 41. It includes a swing cylinder 61 and an extension plate 62. The extension plate 62 is fixed to the rotating rod 42. A downwardly extending fixed plate 63 is provided on the base 52. The tail of the swing cylinder 61 is hinged to the fixed plate 63, and the output end of its piston rod is hinged to the extension plate 62. By extending or retracting the piston rod of the swing cylinder 61, the extension plate 62 can be pushed or pulled, thereby driving the rotating rod 42 to rotate, ultimately achieving synchronous tilting and swinging of all buffer material channels 41.

[0026] 4. Blocking mechanism: As defined in this utility model, and in conjunction with Figure 3 As shown, the blocking mechanism 7 is located at the junction of the outlet of the feeding channel 2 and the inlet of the buffer channel 41. It includes a fixed rod 71, a stop block 72, a blocking cylinder 73, a connecting plate 74, and a rotating shaft 75. The fixed rod 71 is vertically fixed to the frame 1. The stop block 72 is rotatably mounted inside the outlet of the feeding channel 2 via the rotating shaft 75, located between two support plates 23. The connecting plate 74 is fixedly connected to the rotating shaft 75. The cylinder body of the blocking cylinder 73 is hinged to the fixed rod 71, and the end of its piston rod is hinged to the connecting plate 74. The action of the blocking cylinder 73 drives the stop block 72 to rise or fall, thereby controlling the nuclear energy slewing bearing to enter the buffer channel 41 in a single operation.

[0027] 5. Material selection: As defined in this invention, the contact portion between the buffer channel 41 and the nuclear slewing bearing, namely the inner surfaces of the side plate 21 and the support plate 23, is preferably made of nylon. This material can effectively prevent scratches or impacts on the surface of the precision bearing races during the conveying process, and can also significantly reduce the noise generated when the bearing rolls.

[0028] Working principle The working process of this utility model is a cyclical "loading-buffering-unloading" process, as follows: 1. Material loading and buffering stage: Preparation: The lifting device 5 raises the base 52 to the loading position (high position). At the same time, the swing cylinder 61 of the swing device 6 is activated, driving the buffer channel 41 to tilt towards the upward channel 2, so that the inlet of the buffer channel 41 is precisely aligned with the outlet of the loading channel 2. At this time, the stop block 72 of the blocking mechanism 7 is in the lowered state, blocking the subsequent bearing.

[0029] Feeding: The nuclear energy slewing bearing enters the feeding channel 2 from the upstream equipment and rolls towards the outlet under the action of gravity until it is blocked by the stop block 72.

[0030] Single-piece release: After a sensor (not shown in the figure, a standard configuration in the field) detects that a bearing is in place, it sends a signal. The blocking cylinder 73 actuates, lifting the stop block 72 and releasing one bearing. The bearing then rolls into the corresponding buffer channel 41.

[0031] Reset Isolation: After the bearing passes, the blocking cylinder 73 immediately resets, lowers the stop block 72, and blocks the next bearing, ensuring that only one bearing is stored in each buffer channel 41 at a time. Subsequently, the swing cylinder 61 actuates, swinging the buffer channel 41 to a horizontal state, so that the bearing is stably stopped in the middle of the channel, ready for lifting and transfer.

[0032] 2. Material unloading and transfer stage: When the downstream process needs to supply materials, the lifting device 5 drives the base 52 to descend to the unloading position (low position).

[0033] At the same time, the swing device 6 drives the buffer channel 41 to tilt towards the downward channel 3, so that the outlet of the buffer channel 41 is precisely aligned with the inlet of the downward channel 3.

[0034] The bearings that remain in the buffer channel 41 roll out under the action of gravity, enter the discharge channel 3, and roll along the inclined direction of the discharge channel 3, and are finally transported to the downstream process.

[0035] By repeatedly executing the above process, the bearing that enters the buffer area first is always the first to be removed and transported downstream, thus perfectly realizing the "first-in, first-out" logistics management principle. The entire equipment has a compact structure, smooth operation, and a high degree of automation, effectively solving the technical problems of traditional buffering methods, such as large footprint, limited buffer capacity, and inability to guarantee the flow order.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
