Description

Technical Field

[0001] This utility model relates to the field of roller mounting, and in particular to an automatic sorting and feeding structure for cage rollers. Background Technology

[0002] With the rapid development of modern manufacturing, higher demands are being placed on the production efficiency and assembly quality of precision parts. As a key component in bearings, the assembly precision and efficiency of rollers directly affect product performance and lifespan. In traditional manufacturing environments, roller loading and sorting largely rely on manual operation, which is not only inefficient but also labor-intensive, making it difficult to meet the needs of large-volume, high-precision production.

[0003] Currently, common roller sorting and feeding methods mainly rely on manual operation with simple tooling. Workers tap the rollers one by one into the cages. This process usually requires a large amount of manpower, is highly repetitive, and is prone to fatigue leading to decreased efficiency or assembly errors. To improve efficiency, some companies have tried to introduce some mechanical auxiliary devices, such as guide grooves and limit blocks, to achieve preliminary standardized operations.

[0004] However, existing technologies still have many shortcomings. For example, the roller hammering process requires manual hammering, which is not only time-consuming and labor-intensive, but also physically demanding.

[0005] Therefore, it is necessary to provide an automatic sorting and feeding structure for cage rollers to solve the above problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an automatic sorting and feeding structure for cage rollers.

[0007] This utility model provides an automatic sorting and feeding structure for cage rollers, comprising:

[0008] Main body of the workbench;

[0009] A turntable, which is rotatably connected to the surface of the worktable body;

[0010] A limiting block, which is fixedly connected to the surface of the turntable;

[0011] A retainer, which is sleeved on the circumferential surface of the limiting block;

[0012] The mounting mechanism includes a cylinder, a connecting rod, a guide plate, a partial gear, a gear, an extrusion block, a track block, and a drive assembly. Two guide plates are provided. The track block is fixedly connected to the surface of the workbench body. The cylinder is fixedly connected to the surface of the workbench body. The extrusion block is slidably connected within the track block. The output end of the cylinder movably passes through one end of the track block and is fixedly connected to the surface of the extrusion block. The partial gear is fixedly connected to the transmission part of the drive assembly. The connecting rod is fixedly connected to the surface of the turntable. The gear is fixedly connected to the lower end of the connecting rod and meshes with the partial gear. Both guide plates are elastically connected within the track block. The drive assembly is used to drive the partial gear to rotate.

[0013] Preferably, the drive assembly includes a first motor and a drive rod. The first motor is fixedly connected to the surface of the worktable body, one end of the drive rod is fixedly connected to the output end of the first motor, and the other end of the drive rod is fixedly connected to the surface of a portion of the gear.

[0014] Preferably, the track block has a placement groove, the inner wall of the placement groove is fixedly connected to a spring, the guide plate is fixedly connected to one end of the spring, and the guide plate is slidably connected to the inner wall of the placement groove. The two sides of the inner wall of the placement groove are elastically connected to the two guide plates by springs.

[0015] Preferably, the track block has a sliding groove, and the inner wall of the sliding groove is rotatably connected to a plurality of first rollers.

[0016] Preferably, a second roller is rotatably connected inside the track block, a second motor is fixedly connected to the surface of the track block, and the output end of the second motor is fixedly connected to one end of the second roller.

[0017] Preferably, a rubber protective pad is fixedly connected to the surface of the extrusion block.

[0018] Compared with related technologies, the e-government announcement display device provided by this utility model has the following beneficial effects:

[0019] This device utilizes a partial intermittent meshing design between gears. A first motor drives the partial gears to rotate, causing the gears to rotate precisely according to the roller mounting groove spacing, thereby achieving automatic positioning switching of the cage and avoiding manual positioning errors. Combined with the cooperation of a cylinder and a pressing block, the cylinder output pushes the pressing block to slide and precisely press the rollers into the cage, replacing the traditional manual "hammering" action, reducing labor intensity and minimizing the risk of roller damage.

[0020] Through the synergistic effect of the elastic guide plate, guide rollers and rubber protective pads, dynamic calibration and buffer protection of the roller transmission path are achieved, effectively reducing the failure rate of jamming, misalignment and other failures, improving the stability of equipment operation and the quality of roller assembly, and extending the service life of equipment and parts.

Turntable. Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please refer to the following: Figures 1 to 5 An automatic sorting and feeding structure for cage rollers includes:

[0029] Workbench body 1;

[0030] Turntable 9 is rotatably connected to the surface of worktable body 1;

[0031] Limiting block 5 is fixedly connected to the surface of turntable 9;

[0032] Cage 3, which is sleeved on the circumferential surface of the limiting block 5;

[0033] The mounting mechanism includes a cylinder 201, a connecting rod 202, a guide plate 203, a partial gear 204, a gear 205, a pressing block 206, a track block 207, and a drive assembly. Two guide plates 203 are provided. The track block 207 is fixedly connected to the surface of the workbench body 1. The cylinder 201 is fixedly connected to the surface of the workbench body 1. The pressing block 206 is slidably connected within the track block 207. The output end of the cylinder 201 movably passes through one end of the track block 207 and is fixedly connected to the surface of the pressing block 206. The partial gear 204 is fixedly connected to the transmission part of the drive assembly. The connecting rod 202 is fixedly connected to the surface of the turntable 9. The gear 205 is fixedly connected to the lower end of the connecting rod 202 and meshes with the partial gear 204. Both guide plates 203 are elastically connected within the track block 207. The drive assembly is used to drive the partial gear 204 to rotate.

[0034] In the specific implementation process, by controlling the operation of the first motor 401, the drive rod 402 is driven to rotate, thereby driving the partial gear 204 to rotate. Since the partial gear 204 only has some teeth, when it rotates once, it only meshes with some teeth of the gear 205, thereby driving the gear 205 to rotate a certain distance. This distance is consistent with the distance between the adjacent roller mounting slots on the retainer 3, ensuring that after each rotation of the gear 205, the roller mounting slot on the retainer 3 switches to the next position to be installed. At this time, the cylinder 201 is started, and its output end pushes the extrusion block 206 to slide. At the same time, the extrusion block 206 accurately presses the roller that has been positioned in the target mounting slot into the retainer 3, completing the automatic feeding operation. This process completely replaces the traditional manual "hammering" action, which not only reduces labor intensity, but also avoids roller damage or assembly misalignment caused by uneven manual force, significantly improving production efficiency and assembly consistency.

[0035] It should be further explained that the circumferential surface of the limiting block 5 is provided with multiple rubber strips. When the retainer 3 is placed on the circumferential surface of the limiting block 5, the rubber strips on its surface will be squeezed and deformed.

[0036] refer to Figures 1 to 5 As shown, the drive assembly includes a first motor 401 and a drive rod 402. The first motor 401 is fixedly connected to the surface of the worktable body 1. One end of the drive rod 402 is fixedly connected to the output end of the first motor 401, and the other end of the drive rod 402 is fixedly connected to the surface of a partial gear 204.

[0037] It should be noted that the first motor 401 is fixed to the surface of the workbench body 1, and its output end is directly connected to part of the gear 204 through the drive rod 402. When the first motor 401 is started, the drive rod 402 rotates synchronously, driving part of the gear 204 to rotate.

[0038] refer to Figures 1 to 5 As shown, a placement groove 802 is provided in the track block 207. A spring 801 is fixedly connected to the inner wall of the placement groove 802. A guide plate 203 is fixedly connected to one end of the spring 801 and is slidably connected to the inner wall of the placement groove 802. Both sides of the inner wall of the placement groove 802 are elastically connected to the two guide plates by springs.

[0039] It should be noted that the placement slot 802 inside the track block 207 is elastically connected to the guide plate 203 via a spring 801. When the roller is transported along the track block 207, if the roller deviates from the center line due to sliding deviation, the spring 801 drives the guide plate 203 to apply a restoring force to the roller, making it realign with the track center. Multiple springs can be set. At the same time, a telescopic rod can be set inside the spring to connect the placement slot and the guide plate, keeping the guide plate moving horizontally and preventing the guide plate from shifting when the extrusion block generates thrust. Alternatively, a damping seat can be used in conjunction with the spring. The corresponding side of the guide plate can be set as an arc surface. This elastic calibration mechanism can dynamically compensate for the roller's offset during the transport process, ensuring that the roller falls accurately into the target mounting slot, avoiding jamming or assembly failure due to positional deviation, and improving the overall sorting reliability.

[0040] refer to Figures 1 to 5 As shown, a sliding groove 602 is provided inside the track block 207, and multiple first rollers 601 are rotatably connected to the inner wall of the sliding groove 602.

[0041] It should be noted that the sliding groove 602 consists of an inclined groove and a through groove. The through groove is vertical and wider at the top than at the bottom. The diameter of the narrow side is larger than the diameter of the roller to be installed. Multiple first rollers 601 are installed in the inclined groove. When the roller is transported in the sliding groove 602, the multiple first rollers 601 rotate synchronously with the roller, reducing the frictional resistance between the roller and the groove wall. This design prevents the roller from getting stuck in the sliding groove 602 due to friction, ensuring that the roller falls smoothly to the turning point. By reducing energy loss during the transmission process, it reduces abnormal noise or wear caused by the roller stopping, while improving the transmission speed and stability, laying the foundation for the subsequent sorting process.

[0042] refer to Figures 1 to 5 As shown, a second roller 702 is rotatably connected inside the track block 207, and a second motor 701 is fixedly connected to the surface of the track block 207, with the output end of the second motor 701 fixedly connected to one end of the second roller 702.

[0043] It should be noted that the second motor 701 drives the second roller 702 to rotate continuously. When the roller moves to the turning point, the second roller 702 is installed in the through groove of the sliding groove 602. The second roller 702 provides guiding force to the roller by rotating, so that it turns along the predetermined trajectory and enters the subsequent track. This structure effectively solves the problem of the roller getting stuck at the turning point due to inertia or friction, ensures the continuity of roller transmission in complex paths, avoids equipment downtime or roller damage due to material jamming, and improves the overall operating efficiency of the sorting system.

[0044] refer to Figures 1 to 5 As shown, a rubber protective pad is fixedly connected to the surface of the extrusion block 206.

[0045] It should be noted that when the extrusion block 206 pushes the roller into the roller mounting groove of the cage 3, the rubber protective pad absorbs the impact force through flexible contact, preventing the roller from cracking or being damaged on the surface due to hard collision. This design ensures that the roller is pressed in accurately, while extending the service life of the roller and the cage 3, reducing the scrap rate caused by assembly damage, and further improving product yield and assembly quality.

[0046] The working principle of the automatic sorting and feeding structure for retainer rollers provided by this utility model is as follows: The first motor 401 drives the partial gear 204 to rotate, and its intermittent meshing with the gear 205 drives the turntable 9 and retainer 3 to precisely switch positions according to the roller mounting slot spacing. The rollers are transmitted along the sliding groove 602 under the guidance of the first roller 601 and the second roller 702. After being calibrated by the elastic guide plate 203, they fall into the target mounting slot. Finally, the cylinder 201 drives the pressing block 206 to press the rollers into the retainer 3. The rubber protective pad avoids hard damage. This structure solves the problems of low efficiency, high labor intensity, poor assembly accuracy and easy jamming caused by traditional manual sorting and hammering of rollers, and realizes automated, high-precision and continuous production of roller sorting and feeding.
