Description

Technical Field

[0001] This utility model relates to the field of bearing testing technology, and in particular to a bearing surface testing device. Background Technology

[0002] Bearing surface inspection devices are industrial inspection equipment used to automatically inspect the appearance quality of bearings, typically used in quality control stages of production lines. Their core function is to detect defects such as scratches, dents, rust, burrs, dimensional deviations, and deformation on the outer ring, inner ring, or raceway surfaces of bearings, thereby eliminating defective products.

[0003] Existing bearing surface inspection devices typically employ a linear conveyor structure. However, some inspection structures of such devices have high requirements for the height of the bearings. In actual production, if bearings of different models or larger sizes are mixed into the inspection line, or if foreign objects are mixed in due to abnormal feeding, it can easily lead to jamming, collision, or other issues. This can not only cause the production line to stop but may also damage the inspection components, affecting the stability and accuracy of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a bearing surface inspection device that can automatically discharge abnormal workpieces with excessive height, preventing them from entering the inspection mechanism and causing jamming and equipment damage.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a bearing surface inspection device, comprising a feeding mechanism, a conveying mechanism, and a discharging mechanism arranged sequentially, wherein an inspection mechanism is provided on one side of the conveying mechanism, the conveying mechanism includes a conveying platform with a conveying path and a driving structure for driving the bearing to move along the conveying path; a height screening mechanism is also provided at the front end of the conveying platform, the height screening mechanism includes a support plate, a movable block slidably disposed on the support plate in the horizontal direction, and a limiting slider, the limiting slider is disposed below the support plate and fixedly connected to the movable block, and the limiting slider is disposed above the conveying platform, when the bearing height exceeds a preset value, its upper end abuts against the limiting slider, causing the limiting slider to displace; a rotating baffle is provided on the conveying platform, the rotating baffle has a transportation area, the transportation area is connected to the conveying path of the conveying platform; a discharge groove is opened on the rotating baffle, a transmission structure is connected between the movable block and the rotating baffle, the limiting slider drives the rotating baffle to rotate through the transmission structure, causing the discharge groove to rotate onto the conveying path.

[0006] By adopting the above technical solution, the height of the bearing is detected before it enters the detection area. When the bearing height exceeds the limit or foreign objects are mixed in, the limit slider will be driven, thereby driving the rotating baffle to rotate and making the discharge groove rotate onto the conveying path. After the drive structure releases the abnormal workpiece, the abnormal workpiece will fall from the discharge groove, preventing the abnormal workpiece from entering the detection mechanism and causing jamming or damage.

[0007] The present invention is further configured such that: a stop bar is provided on the side of the conveying platform away from the driving structure; the driving structure has a conveying plate; a clamping groove is provided on the conveying plate; the conveying plate is arranged opposite to the stop bar for clamping the bearing and driving the bearing to move along the conveying path.

[0008] By adopting the above technical solution, the bearing is clamped and conveyed by the conveyor plate and the baffle, so that the bearing remains in a relatively fixed state during the conveying process. When the height of the bearing exceeds the preset detection height, its upper end pushes the limit slider to generate displacement, thereby triggering the height screening action.

[0009] The present invention is further configured such that: a fixed block is provided on the support plate, a guide rod is provided on the fixed block, the movable block passes through the guide rod, an elastic element is sleeved on the guide rod, one end of the elastic element abuts against the movable block, and the other end abuts against the fixed block.

[0010] By adopting the above technical solution, the movable block is inserted through the guide rod and reset by the elastic element, which can respond flexibly and reset automatically during the detection process, ensuring that the height limit detection structure has good sensitivity and avoiding jamming.

[0011] The present invention is further configured such that: the transmission structure is connected to the rack of the movable block, the first gear meshing with the rack, and the second gear meshing with the first gear, and the second gear is connected to the rotating baffle via a transmission shaft.

[0012] By adopting the above technical solution, the transmission structure can convert the linear motion of the limit slider into the rotational motion of the rotating baffle. When the limit slider moves horizontally, the rack drives the first gear to rotate, the first gear drives the second gear to rotate, and the second gear drives the rotating baffle to rotate through the transmission shaft, so that the abnormal workpiece falls from the discharge slot.

[0013] The present invention is further configured such that: the limiting slider is provided with a first abutting surface and a second abutting surface facing the bearing transport direction, and the first abutting surface and the second abutting surface form an included angle.

[0014] By adopting the above technical solution, the first abutment surface and the second abutment surface can form multi-point contact with the extra-high part of the bearing, which can stably trigger the displacement of the limit slider according to the different bearing sizes, thereby improving the detection accuracy and the scope of application.

[0015] The present invention is further configured to include a rotating base, wherein the rotating baffle is rotatably disposed on the rotating base, the rotating base is provided with a guide groove, and the rotating baffle is movably disposed within the guide groove.

[0016] By adopting the above technical solution, and by setting a rotating base below the rotating baffle, the rotating baffle rotates in the guide groove, ensuring that the rotating baffle rotates on a horizontal plane, which can effectively guarantee the stability of the baffle rotation and prevent swaying or misalignment during rotation.

[0017] The present invention is further configured such that: a slope is provided below the conveying platform, the upper end of the slope is provided corresponding to the discharge trough, and the lower end of the slope is provided corresponding to the discharge track.

[0018] By adopting the above technical solution, a landslide structure is set under the conveyor platform. The upper end of the landslide corresponds to the discharge chute, and the lower end is connected to the discharge track, so that the discharged abnormal workpieces can slide down smoothly and be collected in a centralized manner.

[0019] The present invention is further configured such that: a bushing is provided at the center of the rotating baffle, the transmission shaft passes through the bushing, the transmission shaft is provided with spline teeth, and the bushing is provided with spline grooves corresponding to the spline teeth.

[0020] By adopting the above technical solution, the drive shaft achieves reliable torque transmission and can be adjusted up and down through the spline teeth and the spline groove of the bushing, while ensuring the synchronization and stability of the rotation.

[0021] The present invention is further configured such that: the driving structure includes a conveying bracket, a first cylinder, a second cylinder and a movable plate disposed on the conveying bracket, the piston rod of the first cylinder is connected to the movable plate to drive the movable plate to move closer to or away from the conveying platform, the second cylinder is disposed on the movable plate, and the conveying plate is connected to the piston rod of the second cylinder to drive the conveying plate to reciprocate along the conveying path.

[0022] By adopting the above technical solution, the first cylinder realizes the fixed-distance conveying of the bearing, and the second cylinder realizes the clamping and releasing action of the bearing, ensuring the stability of the conveying process.

[0023] The present invention is further configured such that: the detection mechanism includes two sets of detection units, each detection unit includes a detection bracket, a light source and a CCD camera disposed on the detection bracket, and a flipping mechanism is provided between the two sets of detection units. The flipping mechanism includes a flipping fixture and a flipping motor for driving the flipping fixture to rotate, and the flipping fixture is provided with a flipping groove.

[0024] By adopting the above technical solution, the testing mechanism uses two sets of testing units in conjunction with a flipping mechanism to realize the surface defect detection of both sides of the bearing; the flipping fixture is driven to rotate by a motor, so that the CCD camera and the light source can respectively detect both sides of the bearing, resulting in a more comprehensive detection range and more accurate detection results.

[0025] In summary, this utility model has the following beneficial effects: 1. The height screening mechanism can monitor the bearing height in real time. When it detects that the bearing is too high or that foreign objects have been mixed in, the limit slider will automatically trigger the transmission structure, causing the rotating baffle to rotate and open the discharge slot, so as to automatically discharge the abnormal workpiece and prevent it from entering the detection mechanism and causing jamming or equipment damage.

[0026] 2. The movable block passes through the guide rod and is reset by the elastic element, which can respond flexibly and reset automatically during the detection process, ensuring that the height limit detection structure has good sensitivity and avoiding jamming.

[0027] 3. A slide and discharge track are set below the discharge trough. Abnormal workpieces slide down naturally through the slide and are collected in a centralized manner. The entire discharge process does not require manual intervention, which facilitates subsequent classification and processing. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings.

[0037] like Figures 1 to 6As shown, the bearing surface inspection device provided by this utility model includes a feeding mechanism 1, a conveying mechanism, and a discharging mechanism 3 arranged in sequence. The feeding mechanism 1 is a feeding conveyor belt, which pushes the bearing to the conveying mechanism through a feeding cylinder. The discharging mechanism 3 is a discharging conveyor belt. An inspection mechanism 4 is provided on one side of the conveying mechanism. The conveying mechanism includes a conveying platform 2 and a drive structure 5. The conveying platform 2 is provided with a conveying path extending in a straight direction for carrying the movement of the bearing. The drive structure 5 is provided on one side of the conveying platform 2 for driving the bearing to move along the conveying path. The drive structure 5 includes a conveying bracket 51, a first cylinder 52, a second cylinder 53, and a movable plate 55. The piston rod of the first cylinder 52 is connected to the movable plate 55. A plate 55 is connected to drive the movable plate 55 to move closer to or away from the conveying platform 2. A second cylinder is set on the movable plate, and a conveying plate 54 is connected to the piston rod of the second cylinder 53 to drive the conveying plate 54 to reciprocate along the conveying path. The conveying plate 54 is provided with a clamping groove 541. The conveying plate 54 is arranged opposite to the stop bar 21 to clamp the bearing and drive the bearing to move along the conveying path. When the conveying plate 54 approaches the stop bar 21, the outline of the clamping groove 541 and the stop bar 21 respectively abut against the two sides of the bearing, thereby realizing the clamping and release of the bearing and ensuring the continuity of the conveying process. A rotating baffle 64 is provided on the conveying platform 2, and a transport area 644 is provided on the rotating baffle 64. The transport area 644 is connected to the conveying platform 2. The conveying paths of platform 2 are interconnected. A height screening mechanism 6 is installed at the front end of conveying platform 2 to detect whether the height of the bearing exceeds a preset range. The height screening mechanism 6 includes a support plate 61, a movable block 62 that can slide horizontally on the support plate 61, and a limiting slider 63 fixedly connected below the movable block 62. The limiting slider 63 is located above the conveying path. When a normal bearing passes by, the limiting slider 63 remains in its original position. When the bearing height exceeds the limit or foreign objects are mixed in, the excess part will cause the limiting slider 63 to move horizontally. The displacement of the limiting slider 63 is transmitted to the rotating baffle 64 on the conveying platform 2 through the transmission structure 7. The transmission structure 7 is set between the movable block 62 and the rotating baffle. Between 64, the transmission structure 7 includes a rack 71 fixedly mounted on the movable block 62, a first gear 72 meshing with the rack 71, and a second gear 73 meshing with the first gear 72. The second gear 73 is connected to the rotating baffle 64 via a transmission shaft 74. When the limiting slider 63 is pushed by the abnormal workpiece and causes the movable block 62 to move horizontally, the movable block 62 drives the rack 71 to move, thereby causing the first gear 72 and the second gear 73 to rotate. The second gear 73 then drives the rotating baffle 64 to rotate via the transmission shaft 74, causing the discharge groove 641 on the rotating baffle 64 to rotate below the conveying path. The abnormal workpiece then falls from the discharge groove 641, thereby realizing the automatic discharge of the abnormal workpiece.

[0038] like Figure 3As shown, in order to ensure the sensitivity and stability of the detection structure, the movable block 62 is inserted through the guide rod 66, and the guide rod 66 is fixedly installed on the fixed block 65. The guide rod 66 is fitted with an elastic element 67, which is a spring structure. One end of the elastic element 67 abuts against the movable block 62, and the other end abuts against the fixed block 65, which is used to reset the movable block 62. After the discharge is completed, the movable block 62 automatically returns to the initial position under the action of the elastic element 67, thereby ensuring the continuity and reliability of the detection.

[0039] like Figure 6 As shown, the limiting slider 63 is provided with a first abutting surface 631 and a second abutting surface 632, which form a certain angle between them. This structure can provide multi-point contact when the bearing is too high, thereby improving the triggering sensitivity and adapting to bearings of different sizes, making the detection results more stable and reliable.

[0040] like Figure 4 and Figure 5 As shown, the rotating baffle 64 is mounted on the rotating base 68, which has a guide groove 681. The rotating baffle 64 rotates within the guide groove 681 to ensure the stability of the baffle during horizontal rotation and prevent swaying, misalignment, or rotation angle error. The rotating baffle 64 has a bushing 643 at its center, and the drive shaft 74 passes through the bushing 643. The drive shaft 74 has spline teeth 741, and the bushing 643 has a corresponding spline groove 6431. The spline structure not only ensures reliable torque transmission but also allows the drive shaft 74 to move up and down to accommodate height adjustment.

[0041] like Figure 3 As shown, a slide 8 structure is provided below the conveying platform 2. The upper end of the slide 8 is set with the discharge trough 641, and the lower end is set with the discharge track 81. When the discharge trough 641 rotates to the lower part of the conveying path, the abnormal bearing falls through the discharge trough 641 and slides into the discharge track 81 along the slide 8, thereby realizing automatic sorting and centralized collection, which is convenient for subsequent processing.

[0042] like Figure 7As shown, the detection mechanism 4 is set on one side of the conveying platform 2 and is used to detect defects on the bearing surface. The detection mechanism 4 includes two sets of detection units. Each set of detection units includes a detection bracket 41, a light source 42 mounted on the detection bracket 41, and a CCD camera 43. A flipping mechanism 9 is set between the two sets of detection units to achieve posture flipping during the bearing detection process. The flipping mechanism 9 includes a flipping fixture 91 and a flipping motor 92. The flipping fixture 91 has a flipping groove 93 inside that matches the outer diameter of the bearing, which is used to hold the bearing during the flipping process. The flipping motor 92 drives the flipping fixture 91 to rotate 180°, so that the two sides of the bearing can be imaged by the two sets of detection units in sequence, thereby realizing surface detection on both sides. The CCD camera 43 transmits the images to the image processing system to identify surface scratches, dents, foreign objects, and other defects, making the detection results more comprehensive and accurate. The width of the flipping groove 93 is the same as the distance from the limit slider 63 to the conveying platform 2 to prevent abnormal workpieces from getting stuck in front of the flipping fixture 91.

[0043] The basic working principle of this utility model is as follows: Before the equipment is run, the operator puts the bearings to be tested into the feeding mechanism 1 in batches. The feeding mechanism 1 transports the bearings to the conveying platform 2 in sequence. After the drive structure 5 on the conveying platform 2 is started, it drives the bearings to move along the predetermined conveying path to the detection area. The bearings first enter the detection area of ​​the height screening mechanism 6. At this time, the limiting slider 63 is located above the bearing and maintains a certain gap with the top of the outer ring of the bearing. It is used to determine whether the height of the bearing exceeds the limit. When a standard-sized bearing passes by, its height will not contact the limiting slider 63, and the limiting slider 63 remains in its original position. If the bearing height exceeds the preset range, or foreign objects are mixed in, causing the overall height to be abnormal, its upper surface will contact the limiting slider 63 and push the limiting slider 63 to slide. The limiting slider 63 is fixedly connected to the movable block 62. The movement of the movable block 62 converts the linear motion into rotational motion through the transmission structure 7 connected to it, thereby driving the rotating baffle 64 to rotate. When the rotating baffle 64 rotates to the preset angle, the discharge groove 641 opened on it is exactly located on the conveying path. At this time, the second cylinder 53 of the drive structure 5 releases the abnormal bearing or foreign object, and the abnormal workpiece falls from the discharge groove 641 onto the slide 8 below, slides along the slide 8 into the discharge track 81, and completes the discharge action. After the discharge action is completed, the elastic element 67 automatically resets the movable block 62 and the limit slider 63, and the rotating baffle 64 also returns to its original position with the transmission structure 7. The conveying path is reopened, and the normal bearing continues to move forward along the conveying path. When the bearing enters the area of ​​the detection mechanism 4, it first passes through the first group of detection units to perform upper surface detection. The light source 42 of the detection unit illuminates the bearing surface, and the CCD camera 43 simultaneously acquires images and transmits the detection data to the control system to determine whether there are defects on the surface. After the detection is completed, the bearing enters the flipping mechanism 9. After the flipping motor 92 starts, it drives the flipping fixture 91 to rotate 180°, so that the lower surface of the bearing flips to the top. After the flipping is completed, the second group of detection units performs optical detection on the other side of the bearing in the same way to achieve comprehensive detection of both sides. The qualified bearings that have been detected continue to enter the unloading mechanism 3 through the conveying mechanism.

[0044] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
