Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bearing press-fitting technology, specifically relating to a multi-station automatic bearing press-fitting workbench. Background Technology
[0002] As a key mechanical component, the accuracy and efficiency of bearing press-fitting directly affect the performance and quality of the entire machine. In modern automated production, the bearing press-fitting process has been gradually replaced by automated equipment instead of manual operation. However, most of the existing mainstream automated press-fitting equipment still adopts a single-station sequential operation mode, that is, the inner and outer rings of the bearing are loaded, aligned and pressed one by one. This single-station working mode has obvious efficiency bottlenecks. Since only one bearing can be pressed in each work cycle, the production cycle of the equipment is limited by the total time consumed by each sequential action (such as loading, positioning, pressing and unloading). The overall production efficiency improvement is limited and it is difficult to meet the capacity requirements of large-scale, batch production lines. Utility Model Content
[0003] The purpose of this utility model is to provide a multi-station automatic bearing press-fitting worktable that can simultaneously position several bearing inner and outer rings and press-fit several bearing inner and outer rings at the same time, effectively increasing the work efficiency of bearing press-fitting.
[0004] The specific technical solution adopted by this utility model is as follows: A multi-station bearing automatic pressing workbench includes a multi-station bearing positioning mechanism and a pressing mechanism, wherein the pressing mechanism is installed above the multi-station bearing positioning mechanism. The multi-position bearing positioning mechanism includes a positioning housing, an outer ring pusher plate, and an inner ring pusher plate. The outer ring pusher plate is slidably installed inside one end of the positioning housing and is provided with a plurality of outer ring placement slots. The inner ring pusher plate is slidably installed inside the other end of the positioning housing and is provided with a plurality of inner ring placement slots. When both the outer ring pusher plate and the inner ring pusher plate slide to the middle of the positioning housing, the inner ring pusher plate is located directly above the outer ring pusher plate, and the inner ring placement slots are aligned with the outer ring placement slots. The pressing mechanism includes a third bracket, which is disposed on one side of the positioning housing. A second electric push rod is installed at one end of the top of the third bracket. A force equalizing block is fixed at the output end of the second electric push rod. Several pressure blocks are evenly fixed at the bottom of the force equalizing block. Several pressing holes are provided on the upper surface of the positioning housing, and each pressing hole is aligned with the merged inner ring placement groove and outer ring placement groove.
[0005] Furthermore, a first bracket is fixed at both ends of the bottom of the positioning housing, and a sliding block is fixed at the bottom of both the outer ring pusher plate and the inner ring pusher plate. The sliding block is slidably connected to the positioning housing. A motor is fixed at one end of the first bracket, and a threaded rod is fixed at the output end of the motor. The threaded rod is threadedly connected to the sliding block.
[0006] Furthermore, a feeding mechanism is installed at the bottom of the multi-station bearing positioning mechanism. The feeding mechanism includes a material box, which is fixed at the bottom of the middle part of the multi-station bearing positioning mechanism. A feeding groove is provided at the connection point between the positioning housing and the material box and below the merged outer ring pusher plate and inner ring pusher plate. Two bottom support plates are slidably installed above the feeding groove, and the bottom support plates are located below the outer ring pusher plate.
[0007] Furthermore, a second bracket is fixed to both sides of the top of the material box, and a first electric push rod is fixed to one end of the second bracket. The output end of the first electric push rod is fixed to the bottom support plate.
[0008] Furthermore, a guide plate is installed at an angle inside the material box and below the material discharge chute.
[0009] The technical effects achieved by this utility model are as follows: This utility model, through the setting of a sliding outer ring pusher plate and an inner ring pusher plate, cooperates with the outer ring material cylinder and the inner ring material cylinder. During the alignment process of the outer ring pusher plate and the inner ring pusher plate, it can automatically pick up the corresponding bearing inner and outer rings, and complete the positioning of the bearing inner and outer rings after alignment. This realizes the synchronous alignment and pressing of multiple bearings, effectively improving the pressing efficiency of bearings. This invention features a base plate that can slide open to both sides after pressing, allowing the bearing to automatically slide into the material box. No manual operation is required during the entire pressing process, ensuring the continuity and stability of production. Attached Figure Description

[0012] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0013] like Figures 1 to 3 As shown, a multi-station bearing automatic pressing workbench includes a multi-station bearing positioning mechanism 1 and a pressing mechanism 3, with the pressing mechanism 3 installed above the multi-station bearing positioning mechanism 1. The multi-position bearing positioning mechanism 1 includes a positioning housing 11, an outer ring pusher plate 12, and an inner ring pusher plate 13. The outer ring pusher plate 12 is slidably installed inside one end of the positioning housing 11 and has several outer ring placement slots. The inner ring pusher plate 13 is slidably installed inside the other end of the positioning housing 11 and has several inner ring placement slots. When both the outer ring pusher plate 12 and the inner ring pusher plate 13 slide to the middle of the positioning housing 11, the inner ring pusher plate 13 is located directly above the outer ring pusher plate 12, and the inner ring placement slots are aligned with the outer ring placement slots. The pressing mechanism 3 includes a third bracket 31, which is disposed on one side of the positioning housing 11. A second electric push rod 32 is installed at one end of the top of the third bracket 31. A force equalizing block 33 is fixed at the output end of the second electric push rod 32. Several pressure blocks 34 are evenly fixed at the bottom of the force equalizing block 33. Several pressing holes are provided on the upper surface of the positioning housing 11, and each pressing hole is aligned with the merged inner ring placement groove and outer ring placement groove. In the above description, the outer ring cylinder 18 and the inner ring cylinder 19 are used to store the inner and outer rings of the bearing, respectively. During the press-fitting operation, the outer ring pusher plate 12 is first controlled to move towards the center of the positioning housing 11. Simultaneously, the inner ring placement groove on the outer ring pusher plate 12 passes under the outer ring cylinder 18. Under the influence of gravity, the outer ring located in the outer ring cylinder 18 falls into the inner ring placement groove and moves to the center of the positioning housing 11. Then, the inner ring pusher plate 13 is controlled to move towards the center of the positioning housing 11. Similarly, ... When the bearing inner ring passes through the inner ring cylinder 19, the bearing inner ring will fall into the inner ring placement groove. After the inner ring pusher plate 13 moves to the middle of the positioning housing 11, the bearing inner ring and outer ring are aligned and the positioning is completed. Then, the second electric push rod 32 is activated to drive the pressure block 34 to descend. The pressure block 34 pushes the outer ring into the inner ring, completing the pressing of the bearing. Since the outer ring pusher plate 12 and the inner ring pusher plate 13 are both provided with several corresponding placement grooves, multiple bearings can be pressed at the same time in a single pressing operation, making the pressing efficiency higher.
[0014] Please refer to it again. Figure 2 As shown, both ends of the bottom of the positioning housing 11 are fixed with first brackets 14, and the bottom of the outer ring pusher plate 12 and the inner ring pusher plate 13 are fixed with sliding blocks 16. The sliding blocks 16 are slidably connected to the positioning housing 11. One end of the first bracket 14 is fixed with a motor 15, and the output end of the motor 15 is fixed with a threaded rod 17. The threaded rod 17 is threadedly connected to the sliding block 16. As described above, when controlling the movement of the outer ring pusher plate 12 and the inner ring pusher plate 13, the threaded rod 17 is driven to rotate by the motor 15. Under the action of the thread and the restriction of the sliding path of the sliding block 16 by the positioning housing 11, the sliding block 16 can be driven to slide below the positioning housing 11, thereby driving the outer ring pusher plate 12 and the inner ring pusher plate 13 to move in position.
[0015] Please refer to it again. Figure 3 As shown, a feeding mechanism 2 is installed at the bottom of the multi-station bearing positioning mechanism 1. The feeding mechanism 2 includes a material box 21, which is fixed at the bottom of the middle part of the multi-station bearing positioning mechanism 1. A feeding groove is provided at the connection point between the positioning housing 11 and the material box 21 and below the merged outer ring pusher plate 12 and inner ring pusher plate 13. Two bottom support plates 25 are slidably installed above the feeding groove. The bottom support plates 25 are located below the outer ring pusher plate 12. A guide plate 22 is installed obliquely inside the material box 21 and below the feeding groove. In the above process, after the bearing pressing step is completed, the bottom support plate 25 located below the outer ring pusher plate 12 is controlled to slide to both sides so that there is no support at the bottom of the bearing. The bearing will slide down the discharge groove into the material box 21. The guide plate 22 provided in the material box 21 can guide the bearing to slide to the front end of the material box 21, making it easier to collect.
[0016] Please refer to it again. Figure 3 As shown, a second bracket 23 is fixed on both sides of the top of the material box 21. A first electric push rod 24 is fixed to one end of the second bracket 23. The output end of the first electric push rod 24 is fixed to the bottom support plate 25. When the bottom support plate 25 is opened and closed, the first electric push rods 24 at both ends can be controlled synchronously.
[0017] The working principle of this utility model is as follows: In use, the threaded rod 17 is driven to rotate by the motor 15, which first drives the outer ring pusher plate 12 to move towards the middle of the positioning housing 11. During the movement, the outer ring placement groove on it will pass under the outer ring material cylinder 18 and automatically pick up a bearing outer ring. Then, the inner ring pusher plate 13 is also driven by the motor 15 to slide towards the middle of the positioning housing 11. The inner ring placement groove on it will pass under the inner ring material cylinder 19 and automatically pick up a bearing inner ring. When the outer ring pusher plate 12 and the inner ring pusher plate 13 meet at the middle of the positioning housing 11, all the inner ring placement grooves will be aligned with the corresponding outer ring placement grooves, completing the bearing inner ring placement. The outer ring is automatically positioned, and then the second electric push rod 32 is activated to drive the force equalizing block 33 and the pressure block 34 to descend, applying pressure to the inner ring of the bearing, so that the inner ring of the bearing is pressed into the outer ring of the bearing, and multiple bearings are pressed in one go. After the pressing is completed, the first electric push rod 24 controls the bottom support plate 25 to slide open to both sides, so that the pressed bearing falls into the material box 21 through the material discharge groove, completing the automatic material discharge. After that, the bottom support plate 25 is reset, and the outer ring push plate 12 and the inner ring push plate 13 are controlled to return to their original positions. During the reset process, the inner ring placement groove and the outer ring placement groove will automatically pick up the inner ring and the outer ring after passing the inner ring material cylinder 19 and the outer ring material cylinder 18, which facilitates continuous pressing work.
[0018] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
