Description

Technical Field

[0001] The utility model belongs to the technical field of bearing ring production equipment, in particular to a mixing and sorting machine for bearing rings. Background Art

[0002] Bearing rings are manufactured through multiple processes including forging, heat treatment, grinding, etc. After the bearing rings are processed and formed, the rings need to be inspected for size and unqualified ones are removed.

[0003] Patent document with announcement number CN208033049U discloses an automatic sorting device for bearing rings. The device uses a sorting plate with through holes of different apertures to screen the bearing rings, thereby achieving automatic classification. This solves the problem that manual sorting of bearing rings is troublesome, inefficient, and costly, and that the surface of the bearing rings is easily damaged during the sorting process, affecting the quality of subsequent production. When the bearing rings of the bearing ring automatic sorting device are transported on the feed guide rail and the sorting plate, the sorting work will not be delayed or interrupted due to the bearing rings being obstructed during the movement. The sorting holes are enlarged successively, which is conducive to the sorting work of the bearing rings, so that the bearing rings with small apertures are screened first, and then the bearing rings with large apertures are screened, so as to ensure the accuracy of the bearing rings during the sorting work. The bearing rings screened by the sorting holes are collected in a centralized manner through the collecting device, which is conducive to the next assembly work. The device is easy to install and has strong flexibility. The elastic telescopic rod is extended and retracted according to the number of sorted and collected bearing rings in the collecting device to expand the volume of the guide groove inside the collecting device. The weight of the collected bearing rings acts vertically on the upper part of the elastic telescopic rod, which has a simple structure and high cost performance.

[0004] Although the above-mentioned automatic bearing ring sorting device can solve the corresponding technical problems, it only sorts the bearing rings according to their outer diameters and is inconvenient to sort the bearing rings according to their heights, thereby reducing the sorting effect of the bearing rings.

[0032] See attached Figure 1-Figure 4 As shown, the mixing and sorting machine for bearing rings of the embodiment of the utility model includes a placement mechanism 100 for containing bearing rings, an inner cavity of which is provided with a height limiting mechanism 200 for limiting the height of the bearing rings, a discharge port of the placement mechanism 100 is provided with a width limiting mechanism 300 for limiting the outer diameter of the bearing rings, and a discharge port of the width limiting mechanism 300 is provided with a conveying mechanism 400 for conveying the bearing rings; the height limiting mechanism 200 includes a connecting plate 210 provided in the inner cavity of the placement mechanism 100, a first inclined plate 220 is integrally formed with the bottom of the connecting plate 210, and two symmetrically arranged support members 230 are provided between the connecting plate 210 and the placement mechanism 100; the width limiting mechanism 300 includes a supporting member 310 provided at the discharge port of the placement mechanism 100, a partition 320 is provided on the top of the supporting member 310, and two parallel connecting members 330 are provided on the partition 320.

[0033] When in use, the height of the bearing ring in the feeder 120 is limited by the first inclined plate 220, so that the bearing ring that exceeds the height cannot pass through the gap between the first inclined plate 220 and the feeder 120. At the same time, the first inclined plate 220 can straighten the bearing ring, and only a single bearing ring can be placed flat through the gap; then the bearing ring with qualified height is pushed to the top of the support plate 311 through the discharge hole 140, and the outer diameter of the bearing ring is limited by the partition 321, so that the bearing ring with a large outer diameter cannot enter the guide. The bearing rings with small outer diameters move to the top of the second inclined plate 312 and then fall directly into the inner cavity of the waste box 500 through the through groove 313. The bearing rings with qualified outer diameters are limited by the support strips 322, so that the bearing rings with qualified outer diameters are pushed to the conveying mechanism 400 through the material guide channel. The bearing rings with qualified height and outer diameter can be transported to the cleaning and packaging line through the conveying mechanism 400 for subsequent packaging, which helps to improve the sorting effect of the bearing rings and ensure the product quality of the bearing rings.

[0034] In an embodiment of the present utility model, the placement mechanism 100 includes a machine base 110, a loader 120 is installed on the top of the machine base 110, and a support bar 130 is horizontally fixedly connected to the inner cavity of the loader 120. The support bar 130 and the connecting plate 210 are connected by a support member 230. The surface of the loader 120 is provided with a discharge hole 140 arranged opposite to the conveying mechanism 400, and the partition 320 is located in the inner cavity of the discharge hole 140. A gap for the bearing ring to pass through is formed between the machine base 110 and the first inclined plate 220.

[0035] In order to achieve a detachable connection between the connecting plate 210 and the support bar 130, and to facilitate the replacement of the height limiting mechanism 200 according to actual usage requirements, in an embodiment of the present utility model, the support member 230 includes a first support plate 231 detachably connected to the top of the support bar 130 by screws, and the top of the first support plate 231 is integrally formed with a second support plate 232 perpendicular to it, and the second support plate 232 is detachably connected to one side of the connecting plate 210 by screws.

[0036] In order to be able to appropriately adjust the height of the height limiting mechanism 200 according to the height of the bearing ring to improve the applicability of the height limiting mechanism 200, a mounting hole 211 for the screw to pass through is vertically opened on the surface of the connecting plate 210. By adjusting the height of the screw in the mounting hole 211, the height of the first inclined plate 220 from the bottom of the inner cavity of the loader 120 can be adjusted.

[0037] In order to achieve the connection between the placement mechanism 100 and the conveying mechanism 400 and guide highly qualified bearing rings to the conveying mechanism 400, the supporting member 310 includes a support plate 311 integrally formed on the loader 120 and located at the discharge hole 140. A second inclined plate 312 is integrally formed on the side of the support plate 311 away from the loader 120. A through groove 313 is formed on the second inclined plate 312. The through groove 313 allows bearing rings with unqualified outer diameters to fall from the second inclined plate 312 to the bottom of the supporting member 310, thereby achieving the effect of outer diameter sorting.

[0038] In order to improve the sorting efficiency of bearing rings, the separator 320 includes three partitions 321 equidistantly distributed on the top of the support plate 311, the bottom of the middle partition 321 is fixedly connected to the support plate 311, and the bottoms of the two side partitions 321 are slidingly connected to the support plate 311. The opposite sides of the two adjacent partitions 321 are integrally formed with support strips 322, the top of the second inclined plate 312 is slidingly connected to the two side partitions 321, and the inner wall surface of the through groove 313 is fixedly connected to the middle partition 321. The three partitions 321 divide the top of the support plate 311 into two material guide channels, and the support strips 322 can support the bearing rings with qualified outer diameters to prevent the bearing rings with qualified outer diameters from falling from the through groove 313 to the bottom of the supporting member 310.

[0039] In order to achieve the connection function of the three partitions 321 and to appropriately adjust the distance between two adjacent partitions 321 according to the outer diameter of the bearing ring to improve the applicability of the partition 320, the connecting member 330 includes a horizontally arranged screw 331, and a through hole 332 for the screw 331 to pass through is opened on the partition 321. Three groups of nuts 333 are threadedly sleeved on the surface of the screw 331, and each group of nuts 333 is arranged one-to-one corresponding to each partition 321.

[0040] In the embodiment of the present invention, each group of nuts 333 is provided with two nuts along the length direction of the screw rod 331 , and the two nuts 333 in each group are in contact with two sides of the surface of the corresponding partition 321 respectively.

[0041] In order to uniformly collect and process the bearing rings with smaller outer diameters, a waste box 500 is placed at the bottom of the supporting plate 311 and the second inclined plate 312 . The waste box 500 is located between the machine base 110 and the conveying mechanism 400 .

[0042] The embodiment of the present invention can limit the height of the bearing ring through the height limiting mechanism 200. The bearing ring that exceeds the height cannot pass through the gap. At the same time, the bearing ring can be straightened so that only a single bearing ring can be placed flat and pass through the gap. The outer diameter of the bearing ring can be limited by the width limiting mechanism 300. The products with large outer diameter cannot pass through the material guide channel, and the products with small outer diameter fall directly into the inner cavity of the waste box 500. Finally, the bearing rings with qualified height and outer diameter can be transported to the cleaning and packaging line through the conveying mechanism 400 for subsequent packaging, which helps to improve the sorting effect of the bearing rings and ensure the product quality of the bearing rings.

[0043] The above shows and describes the basic principles of the present invention. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. The above embodiments and descriptions in the specification are only to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the scope of protection of the present invention.
