[0002] Earless circlips are also called earless retaining rings and equal-section retaining rings. They are usually made of flattened steel wire and wound in this way. This manufacturing method ensures that they have good elasticity while ensuring a certain degree of flexibility to adapt to different installation and use environments. In the prior art, earless circlips can generally be divided into two categories: earless circlips for shafts and earless circlips for holes. Earless circlips for shafts are installed in the grooves on the shaft to limit the axial movement of parts on the shaft, while earless circlips for holes are installed in the grooves of the holes to prevent the parts in the holes from falling out.

[0028] The working principle of the present invention is as follows: the docking mechanism 31 enables the placement tube 21 to be accurately docked with the sleeve 1, the external retaining spring guide mechanism 41 reduces the opening during the installation of the external retaining spring, the internal retaining spring guide mechanism 51 increases the opening during the installation of the internal retaining spring, and the internal retaining spring installation mechanism 61 and the external retaining spring installation mechanism 71 simultaneously push the internal retaining spring and the external retaining spring into the grooves on the sleeve 1 and the shaft core 2.

[0029] Combined with Figure 4 , Attachment Figure 5 As shown: The placement cylinder 21 includes a cylinder body 211, and a limiting ring 212 is fixed at the other end of the cylinder body 211. The docking mechanism 31 includes an adjusting ring 311 rotatably sleeved on the outside of the cylinder body 211 and clamped with the limiting ring 212. One side of the adjusting ring 311 is provided with a plurality of gear seats 213 fixed on the cylinder body 211, and a gear 313 is rotatably provided on the gear seat 213. A screw rod 314 passing through the cylinder body 211 is inserted into the inner thread of the gear 313, and a contact plate 315 contacting the shaft sleeve 1 is provided at the end of the screw rod 314, and a limiting rod 316 slidably inserted into the cylinder body 211 is provided on the contact plate 315.

[0030] Place the sleeve 1 vertically and place the shaft core 2 and the bearing body 3 in the sleeve 1. At this time, the bearing body 3 is placed in the predetermined position in the sleeve 1. The cylinder 211 is connected with the sleeve 1 from top to bottom. During the process, the cylinder 211 is sleeved on the outside of the sleeve 1. After the sleeve 1 contacts the outer retaining spring guide mechanism 41, the adjusting ring 311 is rotated. The adjusting ring 311 drives all the gears 313 to rotate at the same time. The gear 313 drives the contact plate 315 through the screw rod 314. At this time, all the contact plates 315 move toward the sleeve 1 at the same time and contact the sleeve 1. This process can quickly align the axis of the sleeve 1 and the cylinder 211, which is convenient for the subsequent installation of the inner retaining spring and the outer retaining spring.

[0031] Combined with Figure 4 , Attachment Figure 5 As shown: A plurality of through grooves 216 are provided on the side wall of the cylinder 211, and a contraction guide block 415 driven by an external retaining spring guide mechanism 41 and extending inward from top to bottom is provided in each of the through grooves 216.

A plurality of limiting members 217 located at both ends of the through groove 216 and slidably connected to the contraction guide block 415 are provided on the outer wall of the cylinder 211.

[0032] Before the inner and outer circlips are placed and installed, the outer circlip guide mechanism 41 and the inner circlip guide mechanism 51 need to be adjusted so that the opening size of the inner and outer circlips can just reach the predetermined size when the inner and outer circlips are installed later for easy installation; Working principle of the external retaining spring guide mechanism 41: the staff manually rotates the adjustment ring 2 411, and the adjustment ring 2 411 drives all the gears 2 413 to rotate simultaneously through the side gear ring 2 412, and the gear 2 413 drives the screw rod 2 414 to rotate to move all the contraction guide blocks 415 toward the inside of the cylinder 211. When the above-mentioned docking mechanism 31 is working, when the contraction guide block 415 contacts the sleeve 1, the relative movement between the cylinder 211 and the sleeve 1 can be stopped, and when the distance between the inner end faces of the two opposite contraction guide blocks 415 is equal to the inner wall diameter of the sleeve 1, the adjustment ring 2 411 is stopped. At this time, the external retaining spring can better enter the sleeve 1 through a number of contraction guide blocks 415 and enter the slot on the sleeve 1 under the action of the external retaining spring installation mechanism 71.

[0033] Combined with Figure 4 , Attachment Figure 5 As shown: The inner retaining spring guide mechanism 51 includes a retaining spring guide rod 511 located in the cylinder 211, the retaining spring guide rod 511 is fixed to the inner wall of the cylinder 211 through a fixed connecting rod 4 and an outer support rod 517 is provided at the bottom end to enlarge the inner retaining spring opening, the inner retaining spring guide mechanism 51 includes an adjusting rod 513 located in the retaining spring guide rod 511 and threadedly connected to the inner wall of the retaining spring guide rod 511, the end of the adjusting rod 513 is located in the outer support rod 517 and a rotating block 514 is rotatably provided at the end, a plurality of through grooves 512 are provided on the outer support rod 517, a plurality of adjustable guide rods 515 are hinged on the rotating block 514, the end of the adjustable guide rod 515 is hinged with an adjustable guide block 516 whose bottom end is slidably connected to the inner wall of the bottom end of the outer support rod 517, and the adjustable guide rod 515 and the adjustable guide block 516 are jointly plugged into the through groove 512.

[0034] After the sleeve 1 and the cylinder 211 are connected, the outer support rod 517 will press against the shaft core 2, and the inner retaining spring will be sleeved on the shaft core 2 through the outer support rod 517; Working principle of the internal retaining spring guide mechanism 51: an adjusting end head is provided at the other end of the adjusting rod 513, and the staff rotates the adjusting rod 513 through the adjusting end head. During the rotation of the adjusting rod 513, it will also move along the retaining spring guide rod 511 toward the direction of the outer support rod 517, and the adjusting rod 513 drives the rotating block 514 to move. Since the distance between the rotating block 514 and the adjustable guide block 516 is shortened, at this time, one end of the connection between the adjustable guide rod 515 and the rotating block 514 moves toward the adjustable guide block 516, and the other end drives the adjustable guide block 516 to move toward the outside of the through groove 2 512. When the distance between the outer end faces of the two opposite adjustable guide blocks 516 is equal to the diameter of the shaft core 2, the adjusting rod 513 is stopped from rotating. At this time, the internal retaining spring can be sleeved on the shaft core 2 through a plurality of adjustable guide rods 515 and the adjustable guide block 516 and enter the retaining groove on the shaft core 2 under the action of the internal retaining spring installation mechanism 61.

[0035] Combined with Figure 6 , Attachment Figure 7 , Attachment Figure 8 As shown: The inner retaining spring installation mechanism 61 comprises a push rod 611 sleeved on the outer side of the retaining spring guide rod 511, a sleeve 613 is provided at the bottom end of the push rod 611, a push block 612 is provided at the top end, and a plurality of push members 614 that can push the inner retaining spring to be installed are provided on the sleeve 613; The pusher 614 includes a slide bar 615 plugged into the side wall of the bottom end of the sleeve 613, one end of the slide bar 615 is provided with a contact plate 616 that contacts the adjustable guide block 516 and the inner retaining spring at the same time, a spring 618 is provided between the contact plate 616 and the side wall of the sleeve 613 and is sleeved outside the slide bar 615, and the other end of the slide bar 615 is provided with a limit plate 617 located outside the sleeve 613; The external retaining spring installation mechanism 71 includes a connecting block 711 fixedly sleeved on the outside of the push rod 611, a connecting tube 712 is provided at the bottom end of the connecting block 711, a plurality of hollow convex members 713 are provided at the bottom end of the connecting tube 712, two convex members 713 in the plurality of convex members 713 form a group, a pusher member 714 capable of pushing the installation of the external retaining spring is provided between the two convex members 713 in a group, a sliding block 724 is provided on the sliding sleeve outside the push rod 611, and the sliding block 724 contacts the top ends of the plurality of pusher members 714; The pusher 714 includes a central tube 715 located between two convex members 713 in one group, and slide grooves are provided at corresponding positions of the two convex members 713 in one group. Both ends of the central tube 715 are provided with retractable contraction rods 716 with ends located in the slide grooves, and the ends of the contraction rods 716 are provided with sliding plates 717 slidably connected with the slide grooves. The sliding plates 717 are slidably connected with the second slide rod 718 located in the convex member 713. One end of the second slide rod 718 is provided with a limit block 719, and the other end passes through the sliding plate 717 and is provided with a limit block 721 in contact with the external retaining spring at the end. A spring 720 is provided between the limit block 719 and the sliding plate 717 and is sleeved on the outside of the second slide rod 718.

[0036] After the inner circlip guide mechanism 51 and the outer circlip guide mechanism 41 are adjusted, the inner circlip and the outer circlip are placed in the cylinder 211 at the same time. Since the circlip needs to be clamped in the clamping groove, that is, the circlip cannot automatically enter the clamping groove at this time, the inner circlip is located on the adjustable guide rod 515 and the outer circlip is located on the retracting guide block 415. At this time, the inner and outer circlips can be installed in the predetermined clamping grooves at the same time through the inner circlip installation mechanism 61 and the outer circlip installation mechanism 71. Working principle of the inner retaining spring installation mechanism 61 and the outer retaining spring installation mechanism 71: The inner retaining spring installation mechanism 61 and the outer retaining spring installation mechanism 71 are as shown in the attached figure. Figure 3 Assemble as shown, and insert the assembled inner circlip mounting mechanism 61 and the outer circlip mounting mechanism 71 into the cylinder 211. In the present application, all the protrusions 713 are in close contact with the inner wall of the cylinder 211, that is, the inner circlip mounting mechanism 61 and the outer circlip mounting mechanism 71 are both at the axis of the cylinder 211; During the process, the push rod 611 and the sleeve 613 are sleeved on the outside of the inner retaining spring guide mechanism 51. When the sleeve 613 moves toward the cylinder 211, the contact plate 2 616 on the push piece 1 614 moves along the adjustable guide rod 515 and the adjustable guide block 516. When the contact plate 2 616 contacts the inner retaining spring, it will push the inner retaining spring to move toward the shaft core 2. During the process, the inner retaining spring will increase its opening under the action of the adjustable guide rod 515 and the adjustable guide block 516 to match the diameter of the shaft core 2. When the distance between the outer end faces of the two opposite adjustable guide blocks 516 is equal to the diameter of the shaft core 2, the contact plate 2 616 will push the inner retaining spring onto the shaft core 2 through the adjustable guide rod 515 and the adjustable guide block 516. At this time, continue to push the push rod 611 to move the inner retaining spring into the slot on the shaft core 2. When the inner retaining spring installation mechanism 61 is operated, the outer retaining spring installation mechanism 71 will move at the same time. When the protrusion 713 contacts the outer retaining spring, the outer retaining spring will be located between the protrusion 713 and the shrink guide block 415. When the push rod 611 continues to be pushed, the outer retaining spring will reduce its opening under the action of the inner end surface of the shrink guide block 415 to gradually match the inner diameter of the sleeve 1. When the protrusion 713 contacts the sleeve 1, the outer retaining spring is just located at the mouth of the sleeve 1 and the opening size is just enough to enter the sleeve 1. At this time, the inner retaining spring has been installed in place, and then the folding rod 723 on the second pusher 714 is manually adjusted. The folding rod 723 drives the sliding plate 717 to move on the protruding part 713 through the transmission rod 722, so that the limit block 2 721 can contact the outer retaining spring. When the sliding plate 717 moves, the sliding plate 717 on the other side is driven to move synchronously through the central tube 715 and the retracting rod 716. The staff needs to manually adjust the pushing member 2 714 on the three groups of protruding parts 713 so that all the limit blocks 2 721 are in contact with the outer retaining spring, and then manually push the pushing member 2 714 through the sliding block 724, so that the limit block 2 721 drives the outer retaining spring to move into the sleeve 1 and be installed in the inner groove of the sleeve 1.

[0037] The plurality of shrink guide blocks 415 are staggered with the plurality of protrusions 713, and the plurality of adjustable guide blocks 516 are staggered with the plurality of shrink guide blocks 415; The sleeve 613 and the push rod 611 are jointly provided with a through groove 1 619 penetrating the bottom end of the sleeve 613 at the side end, and a through groove 2 726 penetrating the bottom end of the connecting tube 712 is provided at the side end of the connecting tube 712. The fixed connecting rod 4 passes through the through groove 1 619 and the through groove 2 726.
