Description

Technical Field

[0001] The invention relates to the technical field of bearing processing and feeding, in particular to a material sorting device used for bearing processing. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. During the processing of bearings, it is necessary to load the bearings in different processes. By adjusting the position of the bearings, it is convenient for the next process to further process the bearings.

[0003] As attached to this application manual Figure 3 As shown, when the bearings are transferred to different processes for further processing, the conveying position needs to be further adjusted.

[0004] However, when capping is performed on the bored holes opened at equal intervals on the circumferential surface of the bearing, there is a deviation between the position of the bored holes on the circumferential surface and the position of the capping when the bearing is fed and transported to the capping mechanism, and further adjustment is required to cap the bored holes. During the transportation process of the bearings fed in batches, the axis position and the boring hole position will be disturbed by the belt conveyor, resulting in a large deviation between the axis center, the boring hole capping position and the capping position of the capping mechanism during the capping process, which requires further adjustment, having a great impact on the bearing processing.

[0045] Embodiment 2:

[0046] Based on Example 1, this example introduces a material sorting device for bearing processing, such as Figure 3 - Fig.10 As shown, a support frame 5 is installed on one side of the workbench 1 away from the feeding box 2, and the support frame 5 includes two groups of symmetrical support plates 51. The capping mechanism 50 is installed on the support plate 51 away from the feeding box 2. A middle plate 4 is fixedly installed in the middle of the two groups of support frames 5.

[0047] Positioning mechanisms 6 are respectively arranged on both sides of the middle of the workbench 1, and the positioning mechanism 6 includes a movably mounted steering seat 61, and push rods 63 are evenly spacedly mounted on the outer circumference of the steering seat 61, and an arc block 64 is fixedly connected to one end of the push rod 63 away from the steering seat 61, and a slider 65 is slidably mounted on the outer arc surface of the arc block 64, and an arc tooth block 66 is fixedly connected to the top of the slider 65;

[0048] An adjustment mechanism 7 is provided in the middle of the support frame 5, and the adjustment mechanism 7 includes a stroke cylinder 71 fixedly installed on the top of the center plate 4, and the telescopic end of the stroke cylinder 71 is fixedly connected to a lifting frame 72, and a photoelectric switch 70 and an electric turntable 8 are fixedly installed at the bottom of the lifting frame 72. A gear ring 81 is fixedly connected to the output end of the electric turntable 8, and the gear ring 81 is used to adjust the bearing between the two groups of sliders 65. The photoelectric switch 70 is located on the reduction motor of the electric turntable 8. When the electric turntable 8 drives the gear ring 81 to rotate, the photoelectric switch 70 is always at the center of the gear ring 81.

[0049] In this embodiment, when the transmission roller 14 rotates, the second bevel gears 612 on both sides are driven by the first bevel gear 140, so that the two groups of steering seats 61 can rotate synchronously, and the push rods 63 on the two groups of steering seats 61 can be synchronously swung to the top of the conveyor belt 12, and the sliders 65 at the ends of the two groups of push rods 63 can further clamp the bearings that are transported in the center with equal spacing. At this time, the photoelectric switch 70 directly above detects the deviation position between the boring hole on the circumferential surface of the bearing and the capping mechanism 50, and controls the servo motor 11 and the electric turntable 20 to stop working through the controller, and the stroke cylinder 71 drives the lifting frame 72 and the bottom The electric turntable 8 descends to the two groups of arc blocks 64 below. At the same time, the reduction motor drives the transmission gear ring 81 of the electric turntable 8 to rotate evenly. When the gear ring 81 is mounted on the two groups of arc gear blocks 66, the two meshing groups of arc gear blocks 66 and the bearing clamped in the middle are driven to adjust the boring and capping positions so that the boring and capping positions on the bearings match the circumferential arrangement direction initially set by the photoelectric switch 70. In this way, when the bearings transported on the conveyor belt 12 are loaded, multiple groups of circumferentially arranged boring holes on the bearing surface can be matched one by one with the capping positions of the capping mechanism 50, so that multiple groups of boring holes can be capped and formed at one time.

[0050] Among them, the support frame 5 includes a support plate 51 fixed on both sides of the workbench 1, and guide rods 52 are vertically fixedly installed in the guide grooves on both sides of the support plate 51. The convex plates on both sides of the lifting frame 72 are respectively slidably sleeved on the outside of the corresponding guide rods 52. The rotation speed of the servo motor 11 driving the transmission belt 12 is matched with the bearing spacing conveyed in the feed box 2. In this way, after the batches of bearings are conveyed between the straightening mechanisms 3, they can be straightened by the intermittently retractable straightening plates 31, and after the bearings are conveyed between the two groups of positioning mechanisms 6, they can be tightened by the corresponding end sliders 65 of the support rods 63 in the two groups of positioning mechanisms 6.

[0051] Among them, the two sides of the workbench 1 are respectively fixedly installed with a support 60 and an angle seat 613, and a steering shaft 611 is fixedly passed through the bottom of the steering seat 61. The steering shaft 611 is rotatably installed between the support 60 and the angle seat 613 on the same side. The outer sleeve of the steering shaft 611 is fixedly provided with a second bevel gear 612, and the two ends of the transmission roller 14 are respectively fixedly provided with a first bevel gear 140. The outer edge of the first bevel gear 140 is meshed with the outer edge of the second bevel gear 612. The outer side of the workbench 1 is also fixedly installed with a gear box 614, and the gear box 614 is used to rotate the first bevel gear 140. The bevel gear 140 and the second bevel gear 612 are protected, a bottom plate 62 is fixedly installed at the bottom of the inner wall of the steering seat 61, and a guide seat 630 is fixedly installed at equal intervals on the circumference of the bottom plate 62. Through grooves 610 are opened at equal intervals on the outer circumference of the steering seat 61, and the push rod 63 slides between the corresponding through groove 610 and the guide seat 630. A second compression spring 631 is fixedly installed between one end of the push rod 63 close to the bottom plate 62 and the guide seat 630, a slide groove 640 is opened on the inner side of the arc block 64, and the slider 65 slides in the inner wall of the corresponding slide groove 640.

[0052] Among them, a third compression spring 650 is fixedly installed between the slider 65 and the inner wall of the slide groove 640, and the center position of the circle between the two groups of arc-shaped tooth blocks 66 is the same as the center position of the circle of the electric turntable 8. The elastic force of the third compression spring 650 is much smaller than the weight of the bearing. In this way, the transmission gear ring 81 of the electric turntable 8 rotates evenly, and the two meshing groups of arc-shaped tooth blocks 66 and the bearing clamped in the middle are driven. After adjusting the boring hole pressure cover position, the slider 65 generates deformation elastic force under the bearing weight and the friction between the slider 65 and the conveyor belt 12. In this way, after the two groups of push rods 63 continue to rotate, the distance between the two groups of arc blocks 64 gradually increases, and can be reset to the middle of the slide groove 640 by the third compression spring 650, so as to facilitate the adjustment of the boring hole pressure cover position after clamping the subsequent bearing.

[0053] Among them, the photoelectric switch 70 is electrically connected to the adjustment mechanism 7 and the servo motor 11 through a PLC controller. The photoelectric switch 70 can be set to correspond one to one with the number of boring holes on the bearing surface. Under the induction of the photoelectric switch 70, the position deviation of the circumferentially arranged boring holes on the bearing surface and the setting position of the photoelectric switch 70 can be detected, and the reduction motor can be further controlled to control the electric turntable 8 to rotate until the boring hole position after the bearing rotation adjustment matches the set position of multiple photoelectric switches 70.

[0054] Working principle: When in use, the electric turntable 20 driven by the reduction motor in the two sets of feeding boxes 2 rotates at a uniform speed, so that the bearings on the material tray 21 are guided to the conveyor belt 12 through the feed track 22, and the servo motor 11 and the conveyor belt 12 form a conveying mechanism, so that the bearings conveyed in the feeding box 2 can be conveyed in batches, so that the bearings conveyed in the feeding box 2 are conveyed with matching spacing;

[0055] When the bearing is loaded and passes between the two groups of straightening mechanisms 3, the positioning roller 33 can be driven synchronously with the rotating roller 13 through the synchronous belt 34, and the positioning block 330 on the circumference of the positioning roller 33 can rotate in a circle, so that the positioning protrusion 38 at the end of the connecting block 380 can be periodically abutted by the arc-shaped surfaces on both sides of the positioning block 330, so that the positioning tooth block 37 and the connecting block 380 swing periodically, so that the positioning tooth block 37 can periodically abut the positioning rack 310 meshing on the outer edge, so that the straightening plate 31 can be periodically extended and retracted in the guide plate 35 under the cooperation of the first compression spring 36, and the two sides of the bearing on the conveying belt 12 can be pushed in the center, so that the straightening mechanism 3 on both sides of the workbench 1 can straighten the conveyed bearing to the middle of the conveying belt 12 during the bearing conveying process, and place it in the center, so that the subsequent positioning mechanism 6 can clamp the centrally placed bearing;

[0056] When the centered and straightened bearing passes between the two sets of positioning mechanisms 6, the transmission roller 14 rotates, and the second bevel gears 612 on both sides are transmitted through the first bevel gear 140, so that the two sets of steering seats 61 can rotate synchronously, and the push rods 63 on the two sets of steering seats 61 can swing synchronously to the top of the conveyor belt 12, and the sliders 65 at the ends of the two sets of push rods 63 can further clamp the bearings that are centered and transported at equal intervals. At this time, the photoelectric switch 70 directly above detects the deviation position between the boring hole on the circumferential surface of the bearing and the pressing cover mechanism 50, and controls the servo motor 11 and the electric turntable 20 to stop working through the controller, and the stroke cylinder 71 drives the lifting frame 72 and the electric turntable 8 at the bottom are lowered onto the two groups of arc blocks 64 below. At the same time, the reduction motor drives the transmission gear ring 81 of the electric turntable 8 to rotate evenly. When the gear ring 81 is mounted on the two groups of arc gear blocks 66, the two meshing groups of arc gear blocks 66 and the bearing clamped in the middle are driven to adjust the boring and capping positions so that the boring and capping positions on the bearings match the circumferential arrangement direction initially set by the photoelectric switch 70. In this way, when the bearings transported on the conveyor belt 12 are loaded, multiple groups of circumferentially arranged boring holes on the bearing surface can be matched one by one with the capping positions of the capping mechanism 50, so that multiple groups of boring holes can be capped and formed at one time.

[0057] Finally, after the bearings with the boring holes adjusted in position pass through the capping mechanism 50, multiple groups of boring holes can be capped at one time.

[0058] When the bearing processing and sorting device in the present application is actually used, the feed track 22 between the feed box 2 and the conveyor belt 12 can be matched and installed according to the bearing loading size, and the straightening plate 31 between the two sets of straightening mechanisms 3 can be telescoped and adjusted in spacing with the cooperation of the first compression spring 36 to adapt to the centering of bearings of different diameters. Similarly, the two sets of arc blocks 64 in the positioning mechanism 6 and the inner diameter of the end arc tooth block 66 and the gear ring 81 can be disassembled and replaced by bolts to adapt to the loading bearing diameter size.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
