Description

Technical Field

[0001] This utility model relates to the field of guide rod classification technology, specifically a guide rod classification device. Background Technology

[0002] Guide rods are widely used in fields such as machinery manufacturing, automotive parts production, and automated equipment assembly, serving as crucial components for ensuring the precision and stability of mechanical movements. Due to differences in material, specifications, and precision grades, guide rods vary significantly in parameters such as hardness, surface roughness, and diameter. For example, guide rods used in high-precision CNC machine tools have extremely high requirements for straightness and wear resistance. Therefore, it is necessary to classify guide rods.

[0003] For example, Chinese utility model patent application number 202322591800.2 discloses a sorting device for the production of automotive high-pressure connecting rods. The device involves feeding the connecting rods from the feed pipe into a transfer drum, which then enters symmetrical sorting slots on the sorting drum. When the sorting slots are symmetrical with the first discharge port, the connecting rods pass through the first discharge port and are discharged from the first discharge pipe onto the conveyor belt on the first conveyor platform. If the connecting rod specifications do not match the diameter of the first discharge port, the connecting rods can only be discharged from the second discharge port and onto the conveyor belt on the second conveyor platform when the sorting slots are symmetrical with the second discharge port. The entire connecting rod transport process is orderly and does not accumulate. It can orderly sort and transport connecting rods of two different specifications. The device also uses a vibrator to vibrate the feed pipe, the first discharge pipe, and the second discharge pipe to prevent jamming, making it highly practical. However, this device still has certain shortcomings.

[0004] It can only classify connecting rods of two sizes, and cannot classify connecting rods of multiple sizes by range, resulting in low efficiency and low practicality in classifying connecting rods.

[0005] Therefore, we propose a guide rod sorting device to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a guide rod sorting device to solve the problem mentioned in the background art that the current market can only sort connecting rods of two sizes and cannot sort connecting rods of multiple sizes by range, resulting in low efficiency and low practicality in sorting connecting rods.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a guide rod sorting device, comprising a first support frame and a second support frame, wherein the second support frame is provided on the rear side of the first support frame, and a conveyor belt assembly is installed between the second support frame and the first support frame. A limit post is installed on the conveyor belt assembly. A conveying inclined plate is installed on the rear side of the first support frame, and a first feeding chamber, a second feeding chamber, and a third feeding chamber are arranged sequentially from right to left on the upper surface of the conveying inclined plate. A first receiving box, a second receiving box, and a third receiving box are installed below the rear side of the conveying inclined plate. A guide groove is provided on the second support frame, and a movable plate is provided in the guide groove. A limit inclined plate is installed on the front side of the movable plate. Vertical plates are installed on both the left and right sides of the rear side of the second support frame, and threaded rods are installed on the vertical plates through bearing seats.

[0008] Preferably, a servo motor is mounted on the front surface of the first support frame, and an active roller is mounted on the rear side of the first support frame via an output shaft. The active roller is connected to the conveyor belt assembly. An abutment plate is mounted on the rear side of the first support frame. The abutment plate is located below the limiting post, and the guide rod abuts against the abutment plate.

[0009] With the above structural design, the servo motor drives the conveyor belt assembly to operate. In conjunction with the active roller and the abutment plate structure, it ensures stable and uniform conveying of the guide rod, avoiding speed fluctuations or accumulation problems caused by manual feeding. The abutment plate supports the guide rod, keeping the parts in a uniform posture during the conveying process and improving the classification accuracy and consistency.

[0010] Preferably, multiple limiting posts are provided at equal intervals, and the length of the limiting posts is greater than the length of the guide rod.

[0011] With the above structural design, the limiting posts are evenly distributed and longer than the guide rods, which can separate the parts into independent units to prevent them from colliding or overlapping during conveying. This design is especially suitable for the orderly transmission of long rod-shaped parts. This design reduces the risk of material jamming that is common in traditional conveyor belts and improves the smoothness of equipment operation.

[0012] Preferably, a horizontal plate is installed on the upper right side of the first support frame and the second support frame, and a storage box is installed above the horizontal plate.

[0013] The above structural design, combining the horizontal plate and the storage bin, provides temporary storage, facilitating batch loading by operators. The open design of the storage bin supports quick retrieval and improves overall work efficiency.

[0014] Preferably, the first receiving box, the second receiving box, and the third receiving box correspond to the first feeding chamber, the second feeding chamber, and the third feeding chamber, respectively.

[0015] With the above structural design, the first feeding chamber 8 corresponds to the first receiving box 11, the second feeding chamber 9 corresponds to the second receiving box 12, and the third feeding chamber 10 corresponds to the third receiving box 13. Gravity is used to realize the automatic sliding and sorting of the guide rod, avoiding wear and failure caused by complex mechanical transmission.

[0016] Preferably, the limiting inclined plate is located below the limiting post, the movable plate is slidably connected to the guide groove, and the threaded rod is threadedly connected to the movable plate.

[0017] With the above structural design, the sliding connection between the movable plate and the limiting inclined plate allows for precise adjustment of the position of the limiting inclined plate by rotating the threaded rod, thereby changing the critical point for triggering classification by the guide rod. This adjustment process requires no tools and can be operated by a single person, significantly improving the versatility of the equipment.

[0018] Preferably, the threaded rod is fixedly connected to the vertical plate, and limit nuts are installed on both the left and right sides of the threaded rod. The limit nuts are threadedly connected to the threaded rod, and the movable plate is sleeved on the threaded rod.

[0019] With the above structural design, the limiting nuts on both sides of the threaded rod can lock the position of the movable plate, thereby enabling adjustment of the position of the movable plate.

[0022] 2. Flexible adjustment structure: The combination of the threaded rod and the movable plate allows for quick adjustment of the position of the limiting inclined plate, adapting to the classification requirements of guide rods of different specifications. No hardware replacement is required, making operation convenient and adjustment highly accurate.

[0023] 3. Orderly conveying and anti-stacking: The limit posts are evenly distributed on the conveyor belt assembly to ensure that the guide rods are conveyed at intervals, avoiding classification errors caused by stacking and squeezing, and improving the stability of conveying.

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.

[0031] Example 1

[0032] Please see Figures 1-3This utility model provides a technical solution: a guide rod sorting device, including a first support frame 1, a second support frame 2, a conveyor belt assembly 3, limiting posts 4, a horizontal plate 5, a storage box 6, a conveying inclined plate 7, a first feeding chamber 8, a second feeding chamber 9, a third feeding chamber 10, a first receiving box 11, a second receiving box 12, a third receiving box 13, a guide groove 14, a movable plate 15, a limiting inclined plate 16, a vertical plate 17, and a threaded rod 18. The second support frame 2 is arranged on the rear side of the first support frame 1, and the conveyor belt assembly 3 is installed between the second support frame 2 and the first support frame 1. Limiting posts 4 are installed on the conveyor belt assembly 3. Multiple limiting posts 4 are equidistantly arranged, and the length of the limiting posts 4 is greater than the length of the guide rod. The storage box 6... The guide rods are sequentially placed between the limiting posts 4 on the conveyor belt assembly 3, so that one end of the guide rod is above the abutment plate. A horizontal plate 5 is installed on the upper right side of the first support frame 1 and the second support frame 2, and a storage box 6 is installed above the horizontal plate 5. The storage box 6 is used to store the guide rods, making it convenient for workers to retrieve them when classifying the guide rods. A conveying inclined plate 7 is installed on the rear side of the first support frame 1, and the upper surface of the conveying inclined plate 7 is provided with a first feeding chamber 8, a second feeding chamber 9, and a third feeding chamber 10 from right to left. A first receiving box 11, a second receiving box 12, and a third receiving box 13 are installed on the lower rear side of the conveying inclined plate 7. A guide groove 14 is opened on the second support frame 2, and the guide groove 14 is provided with A movable plate 15 is provided, and a limiting inclined plate 16 is installed on the front side of the movable plate 15. The first receiving box 11, the second receiving box 12, and the third receiving box 13 correspond to the first feeding chamber 8, the second feeding chamber 9, and the third feeding chamber 10, respectively. The guide rods move to the left as the conveyor belt assembly 3 moves. When the conveyor belt assembly 3 passes the limiting inclined plate 16, the front end of the smaller guide rod cannot contact the limiting inclined plate 16 and falls into the first feeding chamber 8. The remaining guide rods continue to move to the left. When the front end of the smaller guide rod cannot contact the limiting inclined plate 16 and falls into the second feeding chamber 9, the larger guide rods continue to move to the left until they separate from the limiting inclined plate 16 and fall into the third feeding chamber 10. The first feeding chamber 8, the second feeding chamber 9, and the third feeding chamber 10 are connected. The guide rods in the third feeding chamber 10 are respectively conveyed to the first receiving box 11, the second receiving box 12 and the third receiving box 13 for storage.

The movable plate 15 is slidably connected to the guide groove 14, and the threaded rod 18 is threadedly connected to the movable plate 15. When it is necessary to fine-tune the classification size of the guide rod, the threaded rod 18 is rotated, and the threaded rod 18 drives the movable plate 15 to move left and right. The movable plate 15 drives the limiting inclined plate 16 to move left and right, so as to facilitate the adjustment of the position of the limiting inclined plate 16 and the fine-tuning of the classification size of the guide rod, making the operation more convenient.

[0033] Example 2

[0034] Please see Figures 4-5 This utility model provides a technical solution: a guide rod sorting device, including a limiting nut 19. The difference between this embodiment and embodiment one is that:

The guide rod moves to the left as the conveyor belt assembly 3 moves. When the conveyor belt assembly 3 passes the limiting inclined plate 16, the front end of the smaller guide rod cannot contact the limiting inclined plate 16 and falls into the first feeding chamber 8. The remaining guide rods continue to move to the left. When the front end of the smaller guide rod cannot contact the limiting inclined plate 16 and falls into the second feeding chamber 9, the larger guide rod continues to move to the left until it separates from the limiting inclined plate 16 and falls into the third feeding chamber 10. The guide rods in the first feeding chamber 8, the second feeding chamber 9 and the third feeding chamber 10 are respectively conveyed to the first receiving box 11, the second receiving box 12 and the third receiving box 13 for storage.

[0038] The threaded rod 18, in conjunction with the movable plate 15, allows for quick adjustment of the position of the limiting inclined plate 16, adapting to the classification requirements of guide rods of different specifications. No hardware replacement is required, making operation convenient and providing high adjustment precision, thus completing a series of tasks.
