[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described below in conjunction with specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art.

[0021] This utility model provides an outer ring riveting machine, including a base frame 1, the base frame having an inclined platform 2, the inclined platform 2 having a material discharge hole 3, and a receiving tray 4 movably placed on the inner side of the base frame 1 corresponding to the material discharge hole 3; a positioning plate 7 is provided on the inclined platform 2 at the lower end of the material discharge hole along its width direction, the positioning plate 7 having two symmetrically opened material inlet slots 71 on the side of the positioning plate 7 near the material discharge hole 3, the two material inlet slots 71 are not connected, and the ends of the two material inlet slots 71 that are close to each other are the riveting areas; a top plate 8 parallel to the inclined platform is provided on the inclined platform 2 through a support arm, a first cylinder 9 is fixed on the top plate 8, the shaft end of the first cylinder 9 passes through the top plate 8 and is connected to a stamping plate 10, the lower end face of the stamping plate 10 is provided with two stamping columns 11, the two stamping columns 11 respectively corresponding to the riveting areas of the two material inlet slots 71.

[0022] In this embodiment, a frustum-shaped groove is formed on the lower end face of the stamping column. The cross-section of the frustum-shaped groove is trapezoidal, and its maximum diameter is equal to or slightly larger than the diameter of the top surface of the outer ring. During riveting, the upper end of the outer ring is brought inward to fix the retaining spring and prevent it from coming out. Due to different riveting requirements, the lower end of the stamping column may also have other structures. Therefore, the structure of the lower end of the stamping column is not limited.

[0023] In use, the snap ring is placed inside the outer ring and placed in the feed groove. It is then pushed to the riveting area of ​​the feed groove by the workpiece. Then, the first cylinder is activated, and the stamping plate drives the stamping column to move downward to achieve riveting of the top of the outer ring. After riveting is completed, the first cylinder drives the stamping plate and stamping column to return to the original state. The riveted outer ring is pushed out of the riveting area by other workpieces and falls into the receiving tray through the discharge hole.

[0024] While the above-mentioned structure enables the riveting process of the outer ring, both the pre-riveting feeding and post-riveting unloading require workers to use tools. To automate the operation, an automatic feeding mechanism and an automatic pushing mechanism are also included. The feeding mechanism pushes the outer ring to the riveting area of ​​the feeding slot, and the pushing mechanism pushes the riveted outer ring out of the riveting area, allowing it to fall into the receiving tray through the discharge hole.

[0025] Specifically, a pushing mechanism 5 is provided on the inclined platform 2. The pushing mechanism 5 includes a second cylinder 51 and a first push plate 52. A support plate 12 is provided along the length of the inclined platform 2, located at the lower end of the positioning plate. The support plate 12 is arranged perpendicularly to the positioning plate 7 and its top surface is flush with it. The second cylinder 51 is mounted on the support plate 12, and its shaft end fixing plate is located at the upper end of the support plate. The first push plate 52 is fixed to the shaft end fixing plate of the second cylinder 51. After the outer ring is riveted, the shaft end of the second cylinder extends out and drives the first push plate to move towards the two feed slots of the positioning plate through the fixing plate, pushing the riveted outer ring out of the riveting area and into the receiving tray through the discharge hole.

[0026] Two feeding mechanisms 6 are symmetrically arranged on the inclined platform, and the two feeding mechanisms correspond to two feeding channels respectively. The feeding mechanism 6 includes a third cylinder 61 and a second push plate 62. The third cylinder 61 is arranged outside the feeding channel 71 through a vertical plate, and the second push plate 62 is located above the feeding channel 71 and fixed to the shaft end of the third cylinder 61.

[0027] Furthermore, two slide rails 13 are provided along the length of the inclined platform 2 located at the high end of the positioning plate. Each slide rail 13 consists of two long vertical plates and a base plate disposed between the two long vertical plates. The slide rails correspond one-to-one with the feed troughs, and the bottom surface of the slide rail 13 is flush with the bottom surface of the feed trough 71. The second push plate 62 has a baffle 63 on the side near the slide rail that can block the lower end outlet of the slide rail. The slide rails allow for the placement of multiple outer rings at once.

[0028] When the third cylinder is not in operation, its shaft end extends a certain distance, so that the second push plate is located above the feed channel and a certain distance away from the riveting area. Its baffle can block the slide. At this time, multiple outer rings can be placed in the slide. Due to the action of the second push plate baffle, the outer rings will not fall. When the third cylinder actuates, its shaft end first retracts inward, causing the second push plate to move away from the riveting area of ​​the feed channel, and driving the baffle to move so as not to block the lower end outlet of the slide. Due to the slope of the inclined platform itself, the inner and outer rings of the slide will slide towards the lower end under their own weight. Since the feed channel width is designed to accommodate only one outer ring, only one outer ring falls on the feed channel at this time, while the other outer rings remain in the slide. The shaft end of the third cylinder extends, causing the second push plate to push the outer ring to the riveting area. At the same time, as the second push plate moves, one of its side baffles moves to block the lower end outlet of the slide, preventing the other outer rings from falling. After the riveting is completed, the second cylinder controls the first push plate to push the riveted outer ring out into the receiving tray. At the same time, the third cylinder returns to its original state, waiting for the next action. That is, the shaft end of the third cylinder continues to retract inward, causing the lower end of the slide to open, the outer ring falls, and the third cylinder pushes the outer ring to the riveting area for riveting.

[0029] Furthermore, the first push plate 52 has two vertically formed first arc-shaped channels 521 on one side near the feed channel, each corresponding to an outer ring within the feed channel and matching its shape. Similarly, the second push plate 62 has a vertically formed second arc-shaped channel 621 on one side near the feed channel, corresponding to an outer ring within the feed channel on the same side and matching its shape. This design takes into account the openings on both sides of the feed channel, preventing the outer ring from rotating and shifting towards the discharge hole side during movement.

[0030] Furthermore, a plurality of guide posts 14 are provided between the inclined platform 2 of the base frame and the top plate 8, and the stamping plate 10 is movably fitted around the plurality of guide posts 14. The use of guide posts can improve the accuracy of the movement of the stamping plate, thereby improving the precision of the stamping post.

[0031] Since the stamping column is a wear part and needs to be disassembled later, in this embodiment, to facilitate the detachable installation of the stamping column, a fixing block 15 is provided on the top of the stamping plate 10. The fixing block 15 is connected to the shaft end of the first cylinder 9. The two stamping columns 11 pass through the lower end face of the stamping plate 10 into the interior of the fixing block 15. Bolts are inserted from one side of the fixing block to lock the stamping column. The bolts can be threaded to the fixing block to tighten the stamping column, or they can pass through the fixing block and be threaded to the side of the stamping column.

[0032] Furthermore, a limiting post 16 is threadedly connected to the lower end face of the stamping plate 11, and this limiting post corresponds to the positioning plate area between the two feed slots. By replacing the limiting post with one of different lengths, the pressing distance of the stamping plate can be limited, which is convenient for adjustment according to the height of the outer ring of different specifications.

[0033] Furthermore, two guide plates 17 are arranged side by side along the length of the base frame 1, and the receiving tray 4 is movably placed between the two guide plates 17 for easy and quick placement and positioning.

[0034] Furthermore, to facilitate the placement of unprocessed outer rings and material feeding, the base frame 1 also has a horizontal platform 18 that cooperates with the inclined platform 2. The horizontal platform 18 is provided with a placement area 19, which is connected to the slide rail 13. When the unprocessed outer ring and retaining ring are placed in the placement area, the outer ring can easily slide into the slide rail because it is connected to the placement area.

[0035] The operation process of this outer ring riveting machine is as follows: Multiple unprocessed outer rings and retaining rings are placed in the placement area. The retaining rings are placed inside the outer rings and fall into the slide rail. Under the action of the second push plate baffle, they do not fall. The third cylinder is activated, and the outer rings first fall to the top surface of the feed groove. Then, under the action of the second push plate, they move to the riveting area of ​​the feed groove and remain stationary. Then the first cylinder is activated, and the stamping plate drives the stamping column to move downward to achieve the riveting of the outer rings. After riveting, the first and third cylinders are activated simultaneously to return to the original state. The second cylinder is activated, and the first push plate pushes the riveted outer rings out of the riveting area and they fall into the receiving tray through the discharge hole.
