Description

Technical Field

[0001] The present invention relates to the technical field of material distribution devices, and particularly to a cylindrical bearing roller material distribution mechanism. Background Art

[0002] Bearing rollers are important components in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy.

[0003] According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings; among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial dimensions, vibration and noise are larger, and the price is also higher; rolling bearings generally consist of four parts: outer ring, inner ring, rolling elements and cage; according to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings.

[0004] During the production process, the CRB cylindrical bearing roller material distribution mechanism is specifically designed to rotate and kick out the unqualified rollers after UT inspection for the straight continuous (end-to-end connected) cylindrical bearing rollers. However, due to the relatively smooth end faces of multiple cylindrical rollers and the presence of coupling oil, the rollers will stick together end-to-end on the upper end face of the material distribution mechanism, making it impossible to sort out the unqualified rollers and unable to ensure the product qualification rate. Summary of the Invention

[0005] In view of this, it is necessary to provide a cylindrical bearing roller material distribution mechanism to solve the problem that the end faces of multiple cylindrical rollers are relatively smooth and there is coupling oil, resulting in the end-to-end adhesion on the upper end face of the material distribution mechanism, so that the existing material distribution mechanism cannot perform sorting.

[0027] The preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention.

[0028] As Figure 1 shown, a cylindrical bearing roller sorting mechanism includes a guiding unit 1, a transmission assembly 2, a pressing assembly 3, and a kicking assembly 4. The pressing assembly 3 is arranged at the front end of the transmission assembly 2, and the kicking assembly 4 is arranged in the middle of the transmission assembly 2. Among them,

[0029] the guiding unit 1 is used to carry a plurality of cylindrical bearing rollers 5 connected end to end. The guiding unit 1 is connected to the transmission path of the transmission assembly 2, and a height difference for the cylindrical bearing rollers 5 to lift their heads is formed at the connection position between the guiding unit 1 and the transmission assembly 2. The pressing assembly 3 is arranged above the guiding unit 1 near the connection position to press and convey a plurality of the cylindrical bearing rollers 5 connected end to end through the pressing assembly 3, so that the cylindrical bearing rollers 5 with their heads lifted at the front end are separated from the other cylindrical bearing rollers 5 on the guiding unit 1; the kicking assembly 4 is used to kick out the unqualified cylindrical bearing rollers 5 separated on the transmission path.

[0030] In this specific embodiment, the sorting mechanism can adapt to cylindrical bearing rollers 5 with a diameter of φ20mm - φ60mm and a length of 20mm - 80mm. The cylindrical bearing rollers 5 need to be subjected to UT flaw detection first to find out the defective cylindrical bearing rollers 5.

[0031] As Figure 2 shown, in a specific embodiment, the transmission assembly 2 includes a base, a synchronous belt 22, a first driving wheel 23, a first driven wheel 24, a detection sensor 25, and a first driving unit 26. The base includes a bottom plate 211 and vertical plates 212 fixed on opposite sides of the bottom plate 211. The first driving wheel 23 and the first driven wheel 24 are rotatably connected between the two vertical plates 212. The output shaft of the first driving unit 26 is fixedly connected to the first driving wheel 23. The first driving wheel 23 and the first driven wheel 24 are driven by the synchronous belt 22. The detection sensor 25 is fixedly arranged on the vertical plate 212 between the pressing assembly 3 and the kicking assembly 4. The guiding unit 1 is fixedly arranged on the upper surface of the front end of the bottom plate 211. A height difference for the cylindrical bearing rollers 5 to lift their heads is formed between the guiding unit 1 and the conveying plane of the synchronous belt 22. Specifically, the model of the detection sensor 25 is (O6E701 and O6S701 opposed type).

[0032] In a specific embodiment, the guiding unit 1 is provided with a V-shaped groove 11 for conveniently carrying a plurality of cylindrical bearing rollers 5 connected end to end.

[0033] As Figure 4 andFigure 5 As shown, in a specific embodiment, the pressing assembly 3 includes a mounting side plate 31, a lifting slide table, and at least one pressing wheel assembly 33. The mounting side plate 31 is fixedly connected to one side of the front end of the bottom plate 211. The lifting slide table is fixedly arranged on the mounting side plate 31, and the pressing wheel assembly 33 is fixedly connected to the lifting slide table to press a plurality of the cylindrical bearing rollers 5 connected end to end through the pressing wheel assembly 33.

[0034] As Figure 4 and Figure 5 As shown, in a specific embodiment, the lifting slide table includes two fixed plates 321 fixedly arranged on the mounting side plate 31, a threaded rod 322 rotatably connected between the two fixed plates 321, and a slider 323 rotatably connected to the threaded rod 322. A rotating handle 324 is arranged at the upper end of the threaded rod 322. Two guide rods 325 are fixedly connected between the two fixed plates 321. The slider 323 is also slidably connected to the two guide rods 325. The pressing wheel assembly 33 is fixedly connected to the slider 323. The two guide rods 325 are symmetrically arranged on both sides of the threaded rod 322. By rotating the threaded rod 322, it can be ensured that the slider 323 slides up and down along the two guide rods 325.

[0035] As Figure 6 As shown, in a specific embodiment, the pressing wheel assembly 33 includes a mounting seat 331, a pressing wheel connecting shaft 332, a rubber-coated pressing wheel 333, a spring 334, and an adjusting screw 335. The mounting seat 331 is fixedly connected to the slider 323. One end of the pressing wheel connecting shaft 332 is rotatably connected to the rubber-coated pressing wheel 333. The other end of the pressing wheel connecting shaft 332 is slidably connected in the mounting seat 331. The spring 334 is arranged in the mounting seat 331. The adjusting screw 335 is rotatably connected to the mounting seat 331 to compress the spring 334 to adjust the pressure between the rubber-coated pressing wheel 333 and a plurality of the cylindrical bearing rollers 5 connected end to end on the guiding unit 1. In this specific embodiment, a scale is marked on the mounting seat 331, and the depth of the adjusting screw 335 extending into the mounting seat 331 can be observed through the scale line, so as to determine the magnitude of the pressing force on the spring 334.

[0036] As Figures 4 - 6 As shown, in a specific embodiment, a locking handle 326 for facilitating locking of the slider 323 is arranged on one side of the slider 323. After rotating the threaded rod 322 to adjust the height of the slider 323, the slider 323 can be locked through the locking handle 326.

[0037] As Figure 7As shown, in a specific embodiment, the kicking component 4 includes a support frame 41, a kicking knife 42, and a second driving unit 43. The support frame 41 is fixedly arranged on the bottom plate 211. The second driving unit 43 is fixed on the support frame 41. The second driving unit 43 is electrically connected to the detection sensor 25. The output shaft of the second driving unit 43 is fixedly connected to the kicking knife 42 to drive the kicking knife 42 to kick out the separated unqualified cylindrical bearing rollers 5 on the transmission path. Specifically, according to the signal detected by UT flaw detection for unqualified cylindrical bearing rollers, since the distance between the detection sensor 25 and the kicking knife 42 is constant and the speed of the synchronous belt 22 is also known, when the UT flaw detection issues a signal for an unqualified cylindrical bearing roller 5 (assuming the Nth roller is unqualified), the detection sensor 25 can determine the target unqualified cylindrical bearing roller 5 through the on-off of the signal. Once the detection sensor 25 detects an unqualified cylindrical bearing roller 5, the second driving unit 43 will enter the kicking mode. By the distance between the detection sensor 25 and the kicking knife 42 and the transmission speed of the synchronous belt 22, the time when the unqualified cylindrical bearing roller 5 (assuming the roller does not slip) reaches the position of the kicking knife 42 is matched, so as to match the rotation speed of the second driving unit 33.

[0038] In a specific embodiment, a waste collection device 6 is further included on one side of the kicking component 4.

[0039] As Figure 8 shown, in a specific embodiment, the waste collection device 6 includes two connecting plates 61, a second driving wheel 62 and a second driven wheel 63 rotatably connected between the two connecting plates 61, a conveyor belt 64, a collection box 65, and a third driving unit 66. The output shaft of the third driving unit 66 is fixedly connected to the second driving wheel 62. The second driving wheel 62 and the second driven wheel 63 are driven by the conveyor belt 64. The collection box 65 is fixedly connected to the upper ends of the two connecting plates 61, and a collection groove 651 matching the kicking component 4 is arranged on one side of the collection box 65. The unqualified cylindrical bearing rollers 5 are kicked into the collection box 65 by the kicking knife 42, and the conveyor belt 64 is driven by the third driving unit 66 to convey the unqualified cylindrical bearing rollers 5.

[0040] Working principle: Multiple cylindrical rollers are pushed into the V-shaped groove 11 on the guiding unit 1. According to the diameter of the cylindrical rollers, the threaded rod 322 is rotated to drive the slider 323 to slide up and down along the two guide rods 325 to determine the height of the slider 323. At the same time, the adjusting screw 335 is rotated to squeeze the spring 334 to adjust the pressing force of the rubber-coated pressing wheel 333. A height difference for the cylindrical bearing roller 5 to lift its head is formed between the guiding unit 1 and the conveying plane of the synchronous belt 22. When the rubber-coated pressing wheel 333 squeezes one end of the cylindrical bearing roller 5, there will be a lifting action. At this time, the lower half of the cylindrical bearing roller 5 connected to the lifted cylindrical bearing roller 5 will be separated. During the process of the synchronous belt 22 conveying the cylindrical bearing roller 5, the detection sensor 25 can determine the unqualified cylindrical bearing roller 5. The second driving unit 43 drives the kicking knife 42 to rotate to remove the unqualified cylindrical bearing roller 5 into the collection box 65. The third driving unit 66 drives the conveyor belt 64 to convey to collect the unqualified cylindrical bearing roller 5.

[0041] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
