Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0029] The embodiment of the utility model provides a ring-shaped part feeding mechanism, comprising a carrier plate, a circular turntable assembly and a feeding assembly; the carrier plate serves as a bearing member of the feeding mechanism, and the circular turntable assembly and the feeding assembly are both arranged on the carrier plate, thereby realizing continuous feeding operation; the circular turntable assembly can transfer and feed materials, which can not only provide more materials, but also prevent materials from colliding with each other during the continuous feeding process by feeding materials separately; the feeding assembly is used to receive materials and complete the conveying.

[0030] Hereinafter, the specific structure of each component of the ring-shaped member feeding mechanism provided by the embodiment of the utility model, as well as the connection relationship and position relationship between each component are described in detail with reference to the accompanying drawings.

[0031] like Figures 1 to 5 As shown, in the embodiment of the utility model, the carrier plate 1 includes a bearing surface 11, and a loading hole 12 is provided on the bearing surface 11; the carrier plate 1 is a supporting structure, used to support the circular turntable assembly 2 and the loading assembly 3, wherein the circular turntable assembly 2 is arranged above the bearing surface 11, and the loading assembly 3 is located below the carrier plate 1 (bearing surface 11), and the material conveyed by the circular turntable assembly 2 is conveyed to the loading assembly 3 via the loading hole 12.

[0032] For example, brackets 13 are respectively provided at both ends of the carrier 1 on the back side of the carrying surface 11; the two brackets 13 support the carrier 1 at a certain height, and other components can be arranged below the carrier 1; or, the carrier 1 can be installed at the required position of the fixture through the brackets 13.

[0033] For example, a circular boss is provided at the center of the bearing surface 11, the center of the circular boss coincides with the center of the carrier plate 1, and the circular boss is used to engage with the circular turntable assembly 2 to achieve position limiting of the two structures and achieve more precise installation; or, for example, a bearing is provided on the circular boss, and the circular turntable assembly 2 is connected to the circular boss through the bearing to achieve smooth rotation of the two.

[0034] Continue to refer Figures 1 to 5 As shown, the circular turntable assembly 2 includes a first turntable 21, a columnar material storage structure 22 and a first driving structure 23. The first turntable 21 is arranged on the bearing surface 11. The first driving structure 23 is connected to the first turntable 21 and is used to drive the first turntable 21 to rotate on the bearing surface 11. The first turntable 21 is away from the side of the bearing surface 11. A plurality of columnar material storage structures 22 are circumferentially spaced around the center of the first turntable 21. A feed hole 211 is provided at the bottom of each columnar material storage structure 22 on the first turntable 21, and at least one feed hole 211 overlaps and penetrates with the loading hole 12.

[0035] For example, one or more feeding holes 12 are provided on the carrier 1. When the carrier 1 includes one feeding hole 12, one of the multiple feeding holes 211 overlaps and penetrates the feeding hole 12. When the material in the columnar storage structure 22 is loaded, the first turntable 21 rotates so that the next feeding hole 211 overlaps and penetrates the feeding hole 12, and the first turntable 21 rotates in sequence, thereby realizing continuous loading of the material. When the carrier 1 includes two or more feeding holes 12, a greater number of feeding holes 12 corresponds to a greater number of feeding assemblies 3, that is, a plurality of feeding assemblies 3 perform feeding operations to a plurality of required workstations.

[0036] In the embodiment of the utility model, the columnar material storage structure 22 includes a plurality of material threading rods 221, and the plurality of material threading rods 221 are evenly distributed circumferentially on the first turntable 21; the columnar material storage structure 22 also includes a fixed disk 222, the fixed disk 222 is arranged in parallel with the first turntable 21, and the fixed disk 222 and the first turntable 21 are connected by a connecting column 224, one end of the material threading rod 221 is detachably connected to the fixed disk 222, and the other end is inserted into the feed hole 211. The material threading rod 221 has a certain length, and multiple layers of materials can be stacked on it. For example, when feeding is required, one end of the material threading rod 221 located on the fixed disk 222 is removed, and the material threading operation is performed, and the material threading rod 221 is installed on the fixed disk 222 after completion.

[0037] For example, the number of the piercing rods 221 is 8, or, for example, the number of the piercing rods 221 is determined according to the diameter of the first rotating disk 21 and the outer diameter of the workpiece.

[0038] In the embodiment of the utility model, the columnar storage structure 22 can also be other structural forms, for example, the columnar storage structure 22 includes a plurality of storage barrels, and the plurality of storage barrels are evenly distributed circumferentially on the first rotating disk 21; the axis of the storage barrel is perpendicular to the surface where the first rotating disk 21 is located, and one end of the storage barrel is connected to the port of the feed hole 211. The storage barrel is a straight barrel with a certain height, and a plurality of material pieces are stacked in the storage barrel.

[0039] For example, the number of the material storage barrels is 8, or, for example, the number of the material penetration rods 221 is determined according to the diameter of the first rotating disk 21 and the outer diameter of the material.

[0040] In the embodiment of the utility model, the columnar material storage structure 22 further includes a material pressing block 223; the material pressing block 223 is located at the top of the material rod 221 or the material storage barrel, and is used to descend with the material in the material rod 221 or the material storage barrel. The material pressing block 223 has a certain mass, and under the action of its own gravity, it can press the material downward toward the feeding hole 211, thereby preventing / reducing the material from being unable to move downward normally.

[0041] In the embodiment of the utility model, the first driving structure 23 is located between the two brackets 13, and the first driving structure 23 passes through the carrier plate 1 and is connected to the first turntable 21. After a columnar material storage structure 22 on the first turntable 21 completes loading, the first turntable 21 needs to rotate a certain angle to allow the next columnar material storage structure 22 to load, and the rotation of the first turntable 21 is driven by the first driving structure 23. In the embodiment of the utility model, the first driving structure 23 is driven by a motor, a belt or a cylinder.

[0042] like Figure 5 As shown, for example, the first driving structure 23 includes a gear disk 231, a limit rocker 232, a swing plate 233 and a telescopic driving structure 234; the middle part of the limit rocker 232 is rotatably connected to the swing plate 233, one end of the limit rocker 232 is provided with a limit tooth, the swing plate 233 is provided with an arc groove 235, and the other end of the limit rocker 232 is connected to the telescopic driving structure 234 through a connecting rod; the edge of the gear disk 231 is provided with a plurality of tooth grooves 2311 for engaging with the limit teeth, and a rotating shaft is passed through the middle part of the gear disk 231, one end of the rotating shaft is connected to the first turntable 21, and the other end is rotatably connected to the swing plate 233.

[0043] When the telescopic driving structure 234 contracts, the limit swing rod 232 rotates to separate the limit tooth from the tooth groove 2311. As the telescopic driving structure 234 continues to contract, the limit swing rod 232 contracts from one end of the arc groove 235 to the other end. When the connecting rod connected to the limit swing rod 232 abuts against the end of the arc groove 235, as the telescopic driving structure 234 continues to contract, the swing plate 233 can be pulled to rotate from the first position to the second position. On the contrary, when the telescopic driving structure 234 is extended, the limit swing rod 232 rotates to separate the limit tooth from the tooth groove 2311. Engaged with the tooth groove 2311 at the current position, as the telescopic driving structure 234 continues to extend, the limit rocker 232 shrinks from the other end of the arc groove 235 to one end, and when the connecting rod connected to the limit rocker 232 abuts against the end of the arc groove 235, as the telescopic driving structure 234 continues to extend, the swing plate 233 and the toothed disc 231 can be pushed to rotate synchronously from the second position to the first position. As the toothed disc 231 rotates, the first turntable 21 rotates synchronously, thereby aligning the next columnar storage structure 22 with the loading hole 12.

[0044] For example, the telescopic driving structure 234 is a telescopic cylinder.

[0045] In the embodiment of the utility model, the loading assembly 3 is located on the side of the loading hole 12 away from the feeding hole 211, and is used to receive the materials dropped from the feeding hole 211 and the loading hole 12, and move to the set position. The loading assembly 3 moves back and forth, receives the materials when it moves to the bottom of the loading hole 12, and then moves to the set position to deliver the materials, for example, pushes the materials outside the ring-shaped material loading mechanism, and moves the materials to the next station through a manipulator or the like.

[0046] For example, the loading assembly 3 includes a receiving block 31 and a second driving structure 32, the receiving block 31 is located on the side of the loading hole 12 away from the feeding hole 211, and the second driving structure 32 is connected to the receiving block 31 and is used to drive the receiving block 31 to slide along a set path. For example, the second driving structure 32 is a telescopic cylinder. For example, the loading assembly 3 includes a slide rail 33, the slide rail 33 is connected to the bracket 13, and the receiving block 31 is slidably connected to the slide rail 33. The receiving block 31 is driven to reciprocate on the slide rail 33 through the telescopic rod of the telescopic cylinder, thereby completing the loading operation of the material. For example, a receiving groove is set on the surface of the receiving block 31, and the material is placed in the receiving groove to ensure the stability of the material when it moves with the receiving block 31.

[0047] The embodiment of the utility model also provides a jig, including the above-mentioned annular part feeding mechanism. The jig is a product processing jig, for example, the material in the annular part feeding mechanism is a part used for bearings, the jig is used for the production and manufacturing of bearings, and the annular part feeding mechanism is a part of the jig, which is used to provide annular part raw materials.

[0048] The utility model provides a ring-shaped material feeding mechanism and fixture, each columnar material storage structure 22 stores multiple materials. During the feeding operation, the materials are continuously conveyed to the upper material assembly 3 through the columnar material storage structure 22. When the materials in a columnar material storage structure 22 are conveyed, the first turntable 21 is rotated to align the next columnar material storage structure 22 with the feeding hole 12, and the feeding operation is continued through the columnar material storage structure 22. Repeating the above operation can realize continuous feeding of the feeding structure. The technical solution of the utility model can avoid contact and collision between materials during the feeding process, thereby improving the yield of the product; and the feeding method of the turntable can store more materials, thereby improving the working efficiency of the feeding operation.
