[0050] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0051] Bearings are generally composed of outer rings, inner rings, balls and other parts. Before assembly, the size and raceway of the outer rings and inner rings need to be tested, as well as the matching accuracy between the outer ring and the balls, and between the inner ring and the balls. After the test, the outer rings, inner rings and other parts with different precision need to be sorted to meet different usage needs. At present, the outer rings, inner rings and other parts of the bearing need to be sorted manually after the precision test is completed, which is not only inefficient, but also prone to errors during the sorting process.

[0052] The bearing assembly sorting device provided in the embodiment of the present invention can solve the above-mentioned problem, which will be described in detail below.

[0053] Please refer to Figure 1The sorting device of the bearing assembly comprises a storage assembly 1, a conveying assembly 2, an outer ring transfer assembly 3 and an inner ring transfer assembly 5, wherein the conveying assembly 2 is arranged below the storage assembly 1, wherein the outer ring transfer assembly 3 grabs the outer ring of the movable bearing for size and raceway detection, and the inner ring transfer assembly 5 grabs the inner ring of the bearing for size and raceway detection. After the detection is completed, the qualified outer ring and inner ring of the bearing are placed on the storage assembly 1, and the unqualified outer ring and inner ring of the bearing are uniformly recycled and reused through the conveying assembly 2; the sorting device transfers the outer ring and the inner ring of the bearing to the detection device for detection through the outer ring transfer assembly 3 and the inner ring transfer assembly 5, and then classifies the qualified and unqualified outer rings and inner rings of the bearing, thereby replacing manual sorting and improving the sorting efficiency. Moreover, since it is mechanized and automatic sorting, no mistakes will be made in the process of sorting qualified and unqualified products.

[0054] refer to Figure 2 The material storage component 1 includes an inner ring placement plate 11 and an outer ring placement plate 12 arranged in parallel. The inner ring placement plate 11 is provided with an inner ring placement station 111 and a first through groove 112. The size and shape of the inner ring placement station 111 are adapted to the inner ring of the bearing. The inner ring of the bearing that has passed the inspection is placed on the inner ring placement station 111. The first through groove 112 penetrates the inner ring placement plate 11 and is larger than the inner ring of the bearing. The inner ring of the bearing that has failed the inspection falls from the first through groove 112 to the conveying component 2 below for recovery; similarly, the outer ring placement plate 12 is provided with an outer ring placement station 121 and a second through groove 122. The size and shape of the outer ring placement station 121 are adapted to the outer ring of the bearing. The outer ring of the bearing that has passed the inspection is placed on the outer ring placement station 121. The second through groove 122 penetrates the outer ring placement plate 12 and is larger than the outer ring of the bearing. The outer ring of the bearing that has failed the inspection falls from the second through groove 122 to the conveying component 2 below for recovery.

[0055] Furthermore, the inner ring placement plate 11 and the outer ring placement plate 12 are both installed on the supporting frame beam 10, so that the inner ring placement plate 11 and the outer ring placement plate 12 are at a certain height from the ground.

[0056] refer to Figure 3 and Figure 4 The conveying assembly 2 is used to convey the unqualified bearing inner rings and bearing outer rings that have been screened to a unified recycling place for recycling. The conveying assembly 2 includes an inner ring conveyor belt 201 and an outer ring conveyor belt 221. The inner ring conveyor belt 201 is located directly below the first through slot 112, and the inner ring conveyor belt 201 is used to receive the unqualified bearing inner rings that have fallen from the first through slot 112. The outer ring conveyor belt 221 is located directly below the second through slot 122, and the outer ring conveyor belt 221 is used to receive the unqualified bearing outer rings that have fallen from the second through slot 122. The inner ring conveyor belt 201 is driven to rotate by the inner ring rotating drive member 20, and the outer ring conveyor belt 221 is driven by the outer ring rotating drive member 22.

[0057] Specifically, the two ends of the inner ring transmission belt 201 are sleeved on the two first rollers 205, and the two ends of the two first rollers 205 are rotatably connected to the ear block 207. The ear block 207 is a U-shaped block, and the first rollers 205 are rotatably set in the U-shaped block; one of the first rollers 205 is connected to the inner ring rotation drive member 20 through a coupling, and the first roller 205 is driven to rotate by the inner ring rotation drive member 20, thereby driving the inner ring transmission belt 201 to rotate.

[0058] Furthermore, in order to prevent the inner ring conveyor belt 201 from being deformed by the inner ring of the unqualified bearing on the inner ring conveyor belt 201, a pad 206 is provided between the inner ring conveyor belt 201, and the inner ring conveyor belt 201 is supported by the pad 206, so that the inner ring conveyor belt 201 is always kept straight for transportation. The pad 206 is connected to the first angle seat 204, the first angle seat 204 is connected to the mounting plate 203, and the mounting plate 203 is fixed to the first support 202, so that the pad 206 is always kept at a suitable height. Of course, the ear block 207 is also installed on a separately provided support leg, so that the first roller 205 can smoothly drive the inner ring conveyor belt 201 to rotate.

[0059] The principle of the outer ring rotating driving member 22 driving the outer ring conveyor belt 221 is the same as that of the inner ring rotating driving member 20 driving the inner ring conveyor belt 201. The two ends of the outer ring conveyor belt 221 are sleeved on two second rollers, and the two second rollers are rotatably connected to the second ear blocks. One of the second rollers is connected to the outer ring rotating driving member 22, and the outer ring conveyor belt 221 is driven to rotate by the outer ring rotating driving member 22. Correspondingly, a second pad is provided inside the outer ring conveyor belt 221, and the second pad is connected to the second angle seat 213, and the second angle seat 213 is connected to the second support 212, so as to support the outer ring conveyor belt 221 to maintain a constant height.

[0060] Furthermore, when the assembled bearing is a double-row bearing, since the double-row bearing includes a small inner ring, the sorting device is also provided with a small inner ring placement plate 13, a small inner ring conveyor belt 211 and a small inner ring transfer assembly 4. The small inner ring transfer assembly 4 is used to grab and move the small inner ring of the bearing for testing. The small inner ring placement plate 13 is provided with a small inner ring placement station 131 and a third through groove 132. The size and shape of the small inner ring placement station 131 are adapted to the small inner ring of the bearing. The small inner ring of the bearing that has passed the test is placed on the small inner ring placement station 131. The third through groove 132 penetrates the small inner ring placement plate 13 and is larger than the small inner ring of the bearing. The small inner ring of the bearing that has failed the test falls from the third through groove 132 to the small inner ring conveyor belt 211 below for recovery. The small inner ring placement plate 13 is also installed on the supporting frame beam 10.

[0061] The small inner ring transmission belt 211 is driven to rotate by the small inner ring rotating drive member 21. Its specific setting can refer to the cooperation between the outer ring transmission belt 221 and the outer ring rotating drive member 22. The cooperation between the small inner ring transmission belt 211 and the small inner ring rotating drive member 21 is the same as the cooperation between the outer ring transmission belt 221 and the outer ring rotating drive member 22.

[0062] In order to prevent defective products from sliding off the inner ring conveyor belt 201, the small inner ring conveyor belt 211 and the outer ring conveyor belt 221, guardrails 208 are provided on both sides of the inner ring conveyor belt 201, the small inner ring conveyor belt 211 and the outer ring conveyor belt 221 to block the defective products.

This makes it easy to arrange the entire conveying assembly 2 below the storage assembly 1, and the conveying assembly 2 will not affect the normal grabbing of qualified bearing assembly products.

[0064] refer to Figures 6 to 8 The outer ring transfer assembly 3 is used to grab and move the outer ring of the bearing, and transfer the outer ring of the bearing to the detection device for detection. After the outer ring of the bearing is detected, it is divided into qualified and unqualified according to whether it meets the accuracy requirements. The qualified outer ring of the bearing is placed on the outer ring placement station 121 of the outer ring placement plate 12, and the qualified outer ring of the bearing falls to the outer ring conveyor belt 221 through the second through groove 122. The outer ring transfer assembly 3 is arranged on the side of the outer ring placement plate 12, and the outer ring transfer assembly 3 includes an outer ring air claw drive cylinder 359 and an outer ring claw hand 360. The outer ring claw hand 360 is connected to the outer ring air claw drive cylinder 359, and the outer ring air claw drive cylinder 359 drives the outer ring claw hand 360 to grab the outer ring of the bearing.
