Description

Technical Field

[0001] This invention relates to the field of mechanical component testing technology, specifically to a rotation testing device for mechanical components. Background Technology

[0002] Machine elements, also known as mechanical components, are the basic building blocks of machinery. They are inseparable individual parts that make up machines and equipment. Bearings are a common type of mechanical component in the industrial field. Cylindrical shaft-type industrial parts, such as machine tool spindles, bearings, and bushings, play a crucial role in industry, and their quality affects the service life of the components and even the entire equipment. However, during the production of shaft-type parts, uneven physical or chemical properties in localized areas on their surface are inevitable due to processes or other accidental reasons, leading to quality problems. Therefore, online detection of shaft-type part quality inspection information is of great significance in order to take relevant measures to improve product quality and economic benefits.

[0003] After bearings are manufactured, quality inspection is usually required. If the bearing is stuck inside, it needs to be recycled. However, the current inspection method is mostly manual inspection, which cannot detect all parts of the product. There is a possibility that defective products will be missed in the inspection, and the operation is relatively cumbersome. Summary of the Invention

[0004] The purpose of this invention is to provide a rotation detection device for mechanical components to solve the problems mentioned in the background above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rotation detection device for mechanical parts, comprising a worktable, a fixed frame inside the worktable, a conveyor belt inside the fixed frame, a plurality of detection bearings on the surface of the conveyor belt, a transmission frame inside the worktable on the right side of the fixed frame, a rotating platform rotatably connected to the upper end of the transmission frame, a conveying port fixedly opened on the front side inside the rotating platform, the transmission frame communicating with the conveying port, and a drive block inside the worktable;

[0006] A drive shaft is rotatably connected to the middle of the drive block. An upper rotating wheel is fixedly connected to the upper end face of the drive shaft. A drive gear is fixedly connected to the lower side of the middle of the drive shaft. A lower rotating wheel is fixedly connected to the lower end face of the drive shaft. A drive rack is slidably connected inside the drive block. The drive rack meshes with the lower rotating wheel. The upper rotating wheel is located inside the rotating platform. A friction wheel is rotatably connected to the lower side of the drive block. A driven gear is fixedly connected to the upper end of the friction wheel. The driven gear meshes with the drive gear.

[0007] Furthermore, a fixed rod is fixedly connected inside the workbench, and a driving part is movably connected to the surface of the fixed rod. A mating frame is provided at the left end of the driving part, and a fixed sliding groove is fixedly opened on the surface of the mating frame. A limiting shaft is slidably connected inside the fixed sliding groove. Limiting blocks are fixedly connected to the front and rear ends of the limiting shaft. A limiting rod is fixedly connected to the upper end face of the limiting block. Limiting rings are fixedly connected to the front and rear sides of the fixed frame, and the limiting rod is slidably connected inside the limiting ring.

[0008] Furthermore, a hinge plate is rotatably connected to the right side of the drive unit, and a connecting shaft is rotatably connected to the lower side of the hinge plate. An extrusion block is fixedly connected to both the front and rear sides of the connecting shaft, and the extrusion block is slidably connected to the inside of the drive block's drive card block.

[0009] Furthermore, a connecting plate is fixedly connected to the right side of the drive rack, and a connecting plate is rotatably connected to the lower side of the connecting plate. Several elastic bands are fixedly connected between the connecting plate and the bearing plate, and two sets of elastic rods are fixedly connected to the right end face of the connecting plate.

[0010] Furthermore, a limiting frame is fixedly connected inside the workbench, and a limiting groove is fixedly formed inside the limiting frame. The drive block is slidably connected inside the limiting groove. An electric telescopic rod is fixedly installed inside the workbench, and the upper end face of the electric telescopic rod is fixedly connected to the lower end face of the drive block.

[0011] Furthermore, elastic limiting plates are provided on both the front and rear sides of the fixed frame, and the detection bearing is located between the front and rear elastic limiting plates.

[0012] Furthermore, a conveying sloping plate is fixedly connected to the right end face of the conveyor frame, and an opening is provided at the lower end of the conveyor frame. The opening is located at the right end of the conveyor belt, and a collection box is detachably connected to the right end of the workbench. The lower right end of the conveying sloping plate is located at the upper left end of the collection box.

[0013] Furthermore, several locking blocks are rotatably connected to the rear side of the upper end face of the transmission frame, and the rotating platform is tilted forward.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] As the drive unit moves up and down with the drive block, it drives the upper and lower rotating wheels to rotate in coordination with the meshing transmission of the rack and pinion. When the upper rotating wheel drives the surface bearing to move upward, it drives the inner ring of the bearing to rotate through friction. Defect detection is performed by judging whether the inner ring of the bearing drives the outer ring to rotate. If the bearing is stuck inside, the inner ring of the bearing drives the rotating sleeve to rotate 90 degrees through the outer ring. The outer ring of the bearing that meets the quality requirements is inspected in coordination with the lower rotating wheel and the friction wheel. Compared with the existing technology, the present invention can perform automated defect detection of bearings and classify and collect them according to the bearing quality, which effectively improves the detection effect of the present invention.

[0016] This invention achieves automated bearing detection by setting up a conveyor belt. Elastic limiting plates are set on the front and rear sides of the conveyor belt to ensure that all bearings are on the same straight line, ensuring that each bearing can fall on the transmission shaft to achieve rotation detection, thereby further improving the detection accuracy of this invention.

[0026] If the inner ring of a bearing rotates while simultaneously causing the outer ring to rotate via stuck balls, it needs to be recycled. However, the current manual visual inspection performed after bearing assembly cannot detect all parts of the product, and there is a possibility of missing defective products. Existing inspection equipment will issue an alarm to alert the staff when a defect is detected, and then the staff will collect the defective bearing. However, the above operation is cumbersome, the inspection effect is poor, and it increases the labor cost.

[0027] Example 1, please refer to Figures 1 to 8 The present invention provides a technical solution: a rotation detection device for mechanical parts, including a workbench 1, a fixed frame 2 is arranged inside the workbench 1, a conveyor belt 3 is arranged inside the fixed frame 2, a plurality of detection bearings 6 are arranged on the surface of the conveyor belt 3, a transmission frame 7 is arranged on the right side of the fixed frame 2 inside the workbench 1, a rotating table 8 is rotatably connected to the upper end of the transmission frame 7, a conveying port 10 is fixedly opened on the front side of the interior of the rotating table 8, the transmission frame 7 communicates with the conveying port 10, and a drive block 21 is arranged inside the workbench 1;

[0028] A drive shaft 156 is rotatably connected to the middle of the drive block 21. An upper rotating wheel 157 is fixedly connected to the upper end face of the drive shaft 156. A drive gear 152 is fixedly connected to the lower side of the middle of the drive shaft 156. A lower rotating wheel 155 is fixedly connected to the lower end face of the drive shaft 156. A drive rack 151 is slidably connected inside the drive block 21. The drive rack 151 meshes with the lower rotating wheel 155. The upper rotating wheel 157 is located inside the rotating platform 8. A friction wheel 154 is rotatably connected to the lower side of the drive block 21. A driven gear 153 is fixedly connected to the upper end of the friction wheel 154. The driven gear 153 meshes with the drive gear 152.

[0029] When the drive block 21 drives the drive rack 151 to move downward, the drive rack 151 drives the drive part 15 fixedly connected to it to move downward, and the drive part 15 moves to the right under the drive of the fixed rod 17.

[0030] When the drive block 21 drives the drive rack 151 to move upward, the drive unit 15 moves to the left under the limit of the fixed rod 17. At the same time, the drive rack 151 drives the transmission gear 152 meshing with it to rotate. The transmission gear 152 drives the transmission shaft 156 to rotate and drives the driven gear 153 to rotate. The driven gear 153 drives the friction wheel 154 fixedly connected to it to rotate. When the transmission shaft 156 drives the upper rotating wheel 157 to descend to the lowest point, the bearing 6 moves to the right under the conveyor belt 3 and is sleeved on the upper side of the upper rotating wheel 157. The upper rotating wheel 157 drives the bearing 6 to move upward and rotates its inner ring at the same time.

[0031] If the inner and outer rings of bearing 6 become stuck, the inner ring will drive the outer ring to rotate together. The outer ring will form a friction transmission with the interior of the rotating table 8. The rotating table 8 will rotate 90 degrees under the drive of the stuck bearing 6. The upper rotating wheel 157 will drive the bearing 6 to move upward. When the upper rotating wheel 157 drives the bearing 6 to move downward, the bearing 6 will gradually disengage from the upper rotating wheel 157, thereby realizing the detection of the inner ring of bearing 6.

[0032] If the inner ring of bearing 6 is of acceptable quality, the upper rotating wheel 157 only drives the inner ring of bearing 6 to rotate. When the drive shaft 156 moves to the upper side of the inside of the rotating table 8, the bearing 6 moves into the transmission frame 7. At this time, the drive shaft 156 drives the lower rotating wheel 155 to move downward. During the downward movement, the drive rack 151 drives the connecting plate 29 fixedly connected to it to move to the right. The connecting plate 29 drives the bearing plate 28 rotatably connected to it to move to the right. The bearing plate 28 moves to the right to release the limit on the lower rotating wheel 155. The lower rotating wheel 155 moves downward and contacts the bearing 6. The bearing 6 is sleeved on the surface of the lower rotating wheel 155 and moves upward. At this time, the upper rotating wheel 157 performs inner ring inspection on the next set of bearings 6. Then the drive shaft 156 moves upward, the drive rack 151 drives the bearing plate 28 to move to the left, the lower rotating wheel 155 drives the inner ring of bearing 6 to rotate, and the friction wheel 154 drives the outer ring of bearing 6 to rotate in the opposite direction. Secondary inspection is achieved by controlling the rotation of the inner and outer rings of bearing 6 in different directions.

[0033] In embodiment 2, a fixed rod 17 is fixedly connected inside the workbench 1. A drive unit 15 is movably connected to the surface of the fixed rod 17. A mating frame 31 is provided at the left end of the drive unit 15. A fixed slide groove 16 is fixedly opened on the surface of the mating frame 31. A limiting shaft 11 is slidably connected inside the fixed slide groove 16. Limiting blocks 12 are fixedly connected to the front and rear ends of the limiting shaft 11. A limiting rod 14 is fixedly connected to the upper end face of the limiting block 12. Limiting rings 13 are fixedly connected to the front and rear sides of the fixed frame 2. The limiting rod 14 is slidably connected inside the limiting ring 13.

[0034] A hinge plate 18 is rotatably connected to the right side of the drive unit 15, and a connecting shaft 19 is rotatably connected to the lower side of the hinge plate 18. A pressing block 20 is fixedly connected to both the front and rear sides of the connecting shaft 19, and the pressing block 20 is slidably connected to the inside of the drive block 21.

[0035] When the lower rotating wheel 155 rises to its limit position and begins to descend, the drive unit 15 drives the extrusion block 20 to move to the right through the hinge plate 18. The bearing 6 sleeved on the surface of the lower rotating wheel 155 falls onto the surface of the support plate 28 under the push of the arc surface of the extrusion block 20. Then the support plate 28 drives the bearing 6 to move to the upper side of the inner groove. When the support plate 28 drives the bearing 6 into the inner groove and moves downward, the support plate 28 controls the bearing 6 to move into the inner groove. At the same time, the upper rotating wheel 157 has completed the inner ring rotation detection of the next set of bearings 6.

[0036] In a further embodiment, a connecting plate 29 is fixedly connected to the right side of the drive rack 151, a bearing plate 28 is rotatably connected to the lower side of the connecting plate 29, a plurality of elastic bands 27 are fixedly connected between the bearing plate 28 and the connecting plate 29, and two sets of elastic rods 26 are fixedly connected to the right end face of the connecting plate 29.

[0037] The workbench 1 is internally fixedly connected to a limit frame 23, and the limit frame 23 is internally fixedly provided with a limit groove 24. The drive block 21 is slidably connected inside the limit groove 24. An electric telescopic rod 22 is fixedly installed inside the workbench 1, and the upper end face of the electric telescopic rod 22 is fixedly connected to the lower end face of the drive block 21.

[0038] The front and rear sides of the fixed frame 2 are provided with elastic limiting plates 4, and the detection bearing 6 is located between the front and rear elastic limiting plates 4.

[0039] In Example 4, further, to facilitate the collection of bearings that do not meet quality standards, a conveying sloping plate 9 is fixedly connected to the right end face of the conveyor frame 7, and an opening 25 is provided at the lower end of the conveyor frame 7. The opening 25 is located at the right end of the conveyor belt 3, and a collection box 5 is detachably connected to the right end of the workbench 1. The lower right end of the conveying sloping plate 9 is located at the upper left end of the collection box 5.

[0040] Several locking blocks 30 are rotatably connected to the rear side of the upper end face of the transmission frame 7, and the rotating table 8 is tilted forward.
