Description

Technical Field

[0001] This utility model relates to the field of bearing steel ball conveying technology, specifically a graded conveying mechanism based on the cleaning and drying of bearing steel balls. Background Technology

[0002] In fields such as precision machinery, automobile manufacturing, and high-end instruments, the consistency of bearing steel ball specifications directly affects the assembly accuracy, operational stability, and service life of bearings. The grading and conveying process after cleaning and drying is a key subsequent step in the steel ball production process, and its operational efficiency and grading accuracy play a decisive role in the final product quality and the smoothness of subsequent assembly processes.

[0003] Currently, the grading and conveying of bearing steel balls after cleaning and drying mostly adopts manual sorting or simple conveying and separating equipment. Manual sorting is not only labor-intensive and inefficient, but also prone to mixing of steel balls of different specifications due to human error. Simple conveying and separating equipment often suffers from poor power transmission coordination and unsmooth material conveying and grading. When processing batches of steel balls, it is easy to experience conveying jams or inaccurate grading. Especially when dealing with the simultaneous grading of two or more specifications of steel balls, the structural limitations of existing equipment are more obvious, directly affecting the consistency of steel ball specifications after grading and the efficiency of subsequent production processes.

[0004] To address the aforementioned issues, it is necessary to develop a bearing steel ball cleaning, drying, and grading conveying mechanism with efficient power-coordinated transmission, stable material conveying, and precise grading functions. Through optimized power transmission design and a reasonable grading structure, the stability and grading accuracy of the grading conveying equipment in batch operations can be improved, meeting the technical requirements of the precision manufacturing field for efficient and precise grading and conveying of bearing steel balls after cleaning and drying. Utility Model Content

[0005] The purpose of this invention is to provide a graded conveying mechanism based on the cleaning and drying of bearing steel balls, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A graded conveying mechanism for cleaning and drying bearing steel balls includes a base. A horizontal material cylinder, a first guide frame, and a second guide frame are fixedly installed on the top of the base. A feed hopper is connected to the top of the horizontal material cylinder. A turning mechanism for feeding bearing steel balls is provided inside the horizontal material cylinder. A pushing mechanism for assisting in pushing bearing steel balls is provided on the outer wall of the horizontal material cylinder.

[0008] Furthermore, the horizontal material cylinder has multiple sets of discharge ports evenly spaced on its side wall, and the turning mechanism includes multiple sets of guide rods. Each set of guide rods is inclined and fixed to the inner side wall of the horizontal material cylinder between two adjacent sets of discharge ports. The interior of the horizontal material cylinder is rotatably connected to a rotating rod, and multiple sets of material support plates are fixedly connected to the outer side of the rotating rod. The material support plates are located in the gap between two adjacent guide rods, and a material support groove is provided on the outer side of the material support plates.

[0009] Furthermore, multiple sets of guide rails are fixedly installed on the outer wall of the horizontal material cylinder near the lower part of the discharge port. The guide rails are provided with guide grooves. The front half of the guide groove is narrow and the rear half is wide. A baffle block is fixedly connected to the inner wall of the guide groove.

[0010] Furthermore, the first guide frame is located directly below the front half of the guide trough, and the second guide frame is located directly below the rear half of the guide trough.

[0011] Furthermore, the feeding mechanism includes a frame fixed to the outer wall of the horizontal material cylinder and near the discharge port. The inner wall of the frame is rotatably connected to a rotating shaft. The outer wall of the rotating shaft is rotatably connected to multiple sets of feeding rods via a bracket. A torsion spring is provided at the rotatable connection between the feeding rod and the bracket.

[0012] Furthermore, a motor for driving the rotating rod to rotate is installed at one end of the horizontal material cylinder, and a first sprocket is provided at the other end of the horizontal material cylinder, and the first sprocket is fixedly connected to the end of the rotating rod. A second sprocket is provided on the outside of the frame and fixedly connected to one end of the rotating shaft. The second sprocket and the first sprocket are connected by a chain.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses an electric motor as a power source and forms a linkage transmission through components such as a rotating rod, first and second sprockets, and a chain. It can realize the fully automated operation of bearing steel balls from feeding, lifting and conveying to grading and separation, without the need for manual sorting or pushing, effectively reducing labor costs and operational intensity. At the same time, the grading is accurate and the separation effect is stable. Relying on the structural design of the guide rail guide trough with "narrow front half + wide rear half", combined with the blocking effect of the baffle block on small-diameter steel balls, it can accurately distinguish and separate two types of bearing steel balls with different particle sizes, avoid material mixing, and ensure grading quality.

[0015] 2. The torsion spring in the feeding mechanism allows the feeding rod to deflect flexibly when it contacts large-diameter steel balls, avoiding the problem of rotation jamming caused by the steel balls blocking the rotation. In addition, the rotation mode of the material support plate that is in contact with the inner wall of the horizontal material cylinder can ensure the stable lifting and conveying of steel balls, improving the overall operational stability. Through the cooperation of multiple sets of discharge ports, guide rails and guide frames, continuous conveying and synchronous grading of steel balls can be achieved, reducing the process connection time and helping to improve the overall production efficiency.

[0026] 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.

[0027] Example 1: As Figures 1-8 As shown, the graded conveying mechanism based on the cleaning and drying of bearing steel balls includes a base 1. A horizontal material cylinder 2, a first guide frame 301, and a second guide frame 302 are fixedly installed on the top of the base 1. The top of the horizontal material cylinder 2 is connected to a feed hopper 4. The interior of the horizontal material cylinder 2 is provided with a turning mechanism for feeding bearing steel balls, and the outer wall of the horizontal material cylinder 2 is provided with a pushing mechanism for assisting in pushing the bearing steel balls.

[0028] The horizontal material cylinder 2 has multiple sets of discharge ports 5 evenly spaced on its side wall. The tilting mechanism includes multiple sets of guide rods 601. Each set of guide rods 601 is inclined and fixed to the inner side wall of the horizontal material cylinder 2 between two adjacent sets of discharge ports 5. A rotating rod 602 is rotatably connected inside the horizontal material cylinder 2. Multiple sets of material support plates 603 are fixedly connected to the outer side of the rotating rod 602, and the material support plates 603 are located in the gap between two adjacent guide rods 601. A material support groove is opened on the outer side of the material support plate 603, which can better hold the bearing steel balls.

[0029] Multiple sets of guide rails 7 are fixedly installed on the outer wall of the horizontal feed cylinder 2, near the discharge port 5. It should be noted that the end of the guide rail 7 furthest from the horizontal feed cylinder 2 is inclined downwards to facilitate the stable sliding of the bearing balls. The guide rail 7 has a guide groove. The first half of the guide groove is narrow to ensure that smaller bearing balls fall while preventing larger ones from falling. The second half is wide to ensure that larger bearing balls fall. A baffle block 701 is fixedly connected to the inner wall of the guide groove. Figure 7 As shown, two baffle blocks 701 are installed inside a single guide chute to prevent smaller bearing steel balls from sliding into the rear half of the guide chute.

[0030] The first guide frame 301 is located directly below the front half of the guide trough, and the second guide frame 302 is located directly below the rear half of the guide trough. It should be explained here that the first guide frame 301 is used to receive bearing steel balls with smaller particle size, and the second guide frame 302 is used to receive bearing steel balls with larger particle size.

[0031] Example 2: The feeding mechanism includes a frame 801 fixed on the outer wall of the horizontal material cylinder 2 and above the discharge port 5. The inner wall of the frame 801 is rotatably connected to a rotating shaft 802. The outer wall of the rotating shaft 802 is rotatably connected to multiple sets of feeding rods 803 through a bracket. A torsion spring is provided at the rotatable connection between the feeding rod 803 and the bracket.

[0032] A motor 9 for driving the rotating rod 602 is installed at one end of the horizontal material cylinder 2. A cover 13 is fixedly connected to the side wall of the other end of the horizontal material cylinder 2. Two short shafts are rotatably connected to the inner side walls of the cover 13, and a second bevel gear and a third bevel gear are fixedly connected to the two short shafts respectively. A first bevel gear is fixedly connected to the end of the rotating rod 602 located outside the horizontal material cylinder 2. The second bevel gear meshes with the third bevel gear and the first bevel gear. A first sprocket 10 is sleeved and fixed on the outside of the short shaft connected to the third bevel gear. A second sprocket 11 is fixedly connected to one end of the rotating shaft 802 on the outside of the frame 801. The second sprocket 11 and the first sprocket 10 are connected by a chain 12. Through the mutual meshing transmission of the first bevel gear, the second bevel gear and the third bevel gear, the first sprocket 10 can move in the opposite direction to the driving direction of the motor 9.

[0033] Combining Embodiment 1 and Embodiment 2, the working principle of this utility model is as follows:

[0034] After the cleaning and drying process of the bearing steel balls is completed, the graded conveying mechanism can be started to separate and convey bearing steel balls of different sizes.

[0035] First, the cleaned and dried bearing steel balls are evenly poured into the horizontal material cylinder 2 through the feed hopper 4 at the top of the horizontal material cylinder 2. At this time, the motor 9 installed at one end of the horizontal material cylinder 2 is started, and the motor 9 outputs power to drive the rotating rod 602 inside the horizontal material cylinder 2 to start rotating.

[0036] When the rotating rod 602 rotates, it simultaneously drives the multiple sets of material support plates 603 fixedly connected to its outer side to deflect together. Since the material support plates 603 have material support grooves on their outer sides, and one end of the material support plate 603 is always in contact with the inner circumference of the horizontal material cylinder 2, the material support grooves can simultaneously lift the two different sizes of bearing steel balls in the horizontal material cylinder 2 during rotation. As the rotating rod 602 continues to rotate, the bearing steel balls lifted by the material support plates 603 will gradually roll to the top position on the other side of the rotating rod 602, and then continue to roll to the top of the guide rod 601 between the two adjacent sets of discharge ports 5. Finally, they will smoothly roll through the discharge ports 5 on the side wall of the horizontal material cylinder 2 into the guide rail 7 on the outer wall of the horizontal material cylinder 2, near the discharge port 5.

[0037] Meanwhile, the rotation of the rotating rod 602 will also drive the first bevel gear fixedly connected to its end to rotate synchronously. The first bevel gear drives the third bevel gear to rotate through the second bevel gear, which in turn drives the first sprocket 10 to rotate in the opposite direction. The first sprocket 10 forms a transmission cooperation with the second sprocket 11 on the outside of the frame 801 through the chain 12, which in turn drives the second sprocket 11 to rotate together. Since one end of the rotating shaft 802 rotatably connected to the inner wall of the frame 801 is fixed, the rotating shaft 802 will rotate with the rotation of the second sprocket 11. The multiple sets of feeding rods 803 connected to the outer wall of the rotating shaft 802 through the bracket will also rotate synchronously. During the rotation of the feeding rod 803, if it comes into contact with the bearing steel ball with a larger particle size, the torsion spring at the rotating connection between the feeding rod and the bracket will act, so that the feeding rod 803 can deflect flexibly, effectively avoiding the situation where the rotation is jammed due to the obstruction of the bearing steel ball, and assisting the bearing steel ball to roll stably in the guide rail 7.

[0038] Bearing steel balls of different sizes enter the guide track 7 and roll along the guide groove on the guide track 7. The first half of the guide groove is narrow, and a baffle block 701 is fixedly connected to the inner wall. When a smaller bearing steel ball rolls to the first half of the guide groove, it will fall from the narrow guide groove under the obstruction of the baffle block 701 and fall into the first guide frame 301 located directly below the first half of the guide groove, thus completing the collection of the small-diameter bearing steel balls.

[0039] Larger bearing steel balls, due to their larger size, can smoothly pass through the narrow first half of the guide chute and the stop block 701, continuing to roll into the wider second half of the guide chute. Upon reaching the wider second half, the larger bearing steel balls fall from the guide chute into the second guide frame 302 located directly below the second half of the guide chute, completing the collection of large-diameter bearing steel balls. At this point, the entire graded conveying process of the bearing steel balls is complete.

[0040] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
