Description

Technical Field

[0001] The invention relates to the technical field of assembly tooling, in particular to an earless clip spring quick installation tooling. Background Art

[0002] Earless circlips are also called earless retaining rings with equal cross-section. They are usually made of flattened steel wire. This manufacturing method allows them to have good elasticity while ensuring a certain degree of flexibility to adapt to different installation and use environments. In the existing technology, 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 groove on the shaft to limit the axial movement of parts on the shaft, while earless circlips for holes are installed in the groove of the hole to prevent the parts in the hole from falling out.

[0003] In the prior art, shaft circlip pliers are generally used to install earless shaft circlips on shaft sleeves and shaft cores. The shaft circlip pliers are used to change the opening size of the shaft circlip so that the earless shaft circlips can be placed in the grooves on the shaft sleeve and shaft core to complete the installation. However, when using shaft circlip pliers to simultaneously install the earless shaft circlips in the grooves on the shaft sleeve and shaft core, the two earless shaft circlips need to be installed in sequence, and cannot be installed at the same time, which makes the installation efficiency of the earless shaft circlips low.

Specific embodiments

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Combined with the attached Figure 1 and the attached Figure 2 and the attached Figure 3 as shown:

[0033] A quick installation tool for an earless circlip includes a vertically placed bushing 1, in which a shaft core 2 and a bearing body 3 are arranged. The shaft core 2 is located at the axis center of the bearing body 3, and clamping grooves are provided at corresponding positions on the inner wall of the bushing 1 and the shaft core 2.

[0034] A placing cylinder 21 is provided on the bushing 1. The placing cylinder 21 and the bushing 1 are butt-jointed and fixed by a docking mechanism 31. An external circlip guiding mechanism 41 for reducing the opening of the external circlip is provided on the placing cylinder 21, and an internal circlip guiding mechanism 51 for increasing the opening of the internal circlip is provided inside. An internal circlip installation mechanism 61 and an external circlip installation mechanism 71 for simultaneously installing the external circlip and the internal circlip into the clamping groove are provided between the inner wall of the placing cylinder 21 and the internal circlip guiding mechanism 51.

[0035] The working principle of the present invention: The docking mechanism 31 accurately docks the placing cylinder 21 and the bushing 1. The external circlip guiding mechanism 41 reduces the opening during the installation of the external circlip, the internal circlip guiding mechanism 51 increases the opening during the installation of the internal circlip, and the internal circlip installation mechanism 61 and the external circlip installation mechanism 71 simultaneously push the internal circlip and the external circlip into the clamping grooves on the bushing 1 and the shaft core 2.

[0036] Combined with the attached Figure 4 and the attached Figure 5 as shown:

[0037] The placing cylinder 21 includes a cylinder body 211. A first limiting ring 212 is fixed at the other end of the cylinder body 211. The docking mechanism 31 includes an adjusting ring 311 that rotates outside the cylinder body 211 and is clamped with the first limiting ring 212. A number of first gear seats 213 fixed on the cylinder body 211 are provided on one side of the adjusting ring 311. A first gear 313 is rotatably arranged on the first gear seat 213. A first lead screw 314 passing through the cylinder body 211 is inserted into the first gear 313 in a threaded manner. A first contact plate 315 in contact with the bushing 1 is provided at the end of the first lead screw 314. A limiting rod 316 slidably inserted into the cylinder body 211 is provided on the first contact plate 315.

[0038] Vertically place the bushing 1 and place the shaft core 2 and the bearing body 3 inside the bushing 1. At this time, the bearing body 3 is placed at a predetermined position inside the bushing 1. Connect the cylinder body 211 to the bushing 1 from top to bottom. During the process, the cylinder body 211 is sleeved outside the bushing 1. After the bushing 1 contacts the outer snap ring guide mechanism 41, rotate the first adjusting ring 311. The first adjusting ring 311 drives all the first gears 313 to rotate simultaneously. The first gears 313 drive the contact plate 315 through the first lead screw 314. At this time, all the contact plates 315 move towards the bushing 1 simultaneously and contact the bushing 1. This process can quickly align the axes of the bushing 1 and the cylinder body 211, facilitating the subsequent installation of the inner snap ring and the outer snap ring.

[0039] Combined with the attached Figure 4 and the attached Figure 5 as shown:

[0040] A number of first through slots 216 are provided on the side wall of the cylinder body 211. A contraction guide block 415 driven by the outer snap ring guide mechanism 41 and extending inward from top to bottom is provided in each of the first through slots 216. One end of the outer wall of the cylinder body 211 is fixed with a second limiting ring 214. The outer snap ring guide mechanism 41 includes an adjusting ring 411 that rotates outside the cylinder body 211 and is clamped with the second limiting ring 214. A number of second gear seats 215 fixed to the outer wall of the cylinder body 211 are provided on one side of the second limiting ring 214. A second gear 413 is rotatably provided on each of the second gear seats 215. A second side gear ring 412 meshing with the second gear 413 is provided on the side end of the adjusting ring 411. A second lead screw 414 threadedly connected to one end of the contraction guide block 415 is provided on the second gear 413. A number of limiting members 217 that are located at both ends of the first through slots 216 and are slidably connected to the contraction guide block 415 are provided on the outer wall of the cylinder body 211.

[0041] Before installing the inner snap ring and the outer snap ring, the outer snap ring guide mechanism 41 and the inner snap ring guide mechanism 51 need to be adjusted so that the opening sizes of the inner and outer snap rings just reach the predetermined sizes for subsequent installation of the inner and outer snap rings;

[0042] Working principle of the outer snap ring guide mechanism 41: The operator manually rotates the adjusting ring 411. The adjusting ring 411 drives all the second gears 413 to rotate simultaneously through the second side gear ring 412. The second gears 413 drive the second lead screws 414 to rotate, causing all the contraction guide blocks 415 to move towards the inside of the cylinder body 211. When the above docking mechanism 31 is working, when the contraction guide block 415 contacts the bushing 1, the relative movement between the cylinder body 211 and the bushing 1 can be stopped. When the distance between the inner end faces of two opposite contraction guide blocks 415 is equal to the inner diameter of the bushing 1, stop rotating the adjusting ring 411. At this time, the outer snap ring can better enter the bushing 1 through a number of contraction guide blocks 415 and enter the card slot on the bushing 1 under the action of the outer snap ring installation mechanism 71.

[0043] Combined with the attached Figure 4 and the attachedFigure 5 As shown in:

[0044] The internal circlip guiding mechanism 51 includes a circlip guiding rod 511 located inside the cylinder body 211. The circlip guiding rod 511 is fixed to the inner wall of the cylinder body 211 through a fixed connecting rod 4, and an outer support rod 517 for increasing the opening of the internal circlip is provided at the bottom end. The internal circlip guiding mechanism 51 includes an adjusting rod 513 located inside the circlip guiding rod 511 and threadedly connected to the inner wall of the circlip guiding rod 511. The end of the adjusting rod 513 is located inside the outer support rod 517, and a rotating block 514 is rotatably provided at the end. A number of second through slots 512 are provided on the outer support rod 517. A number of adjustable guide rods 515 are hinged to the rotating block 514. The end of the adjustable guide rod 515 is hinged to 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. The adjustable guide rod 515 and the adjustable guide block 516 are jointly inserted into the second through slots 512.

[0045] After the bushing 1 is docked with the cylinder body 211, the outer support rod 517 will abut against the shaft core 2, and the internal circlip will be sleeved on the shaft core 2 through the outer support rod 517;

[0046] Working principle of the internal circlip guiding mechanism 51: An adjusting end is provided at the other end of the adjusting rod 513. The staff rotates the adjusting rod 513 through the adjusting end. During the rotation of the adjusting rod 513, it will also move along the circlip guiding rod 511 towards the outer support rod 517. 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 towards the adjustable guide block 516, and the other end drives the adjustable guide block 516 to move towards the outside of the second through slot 512. When the distance between the outer end faces of two opposite adjustable guide blocks 516 is equal to the diameter of the shaft core 2, stop rotating the adjusting rod 513. At this time, the internal circlip can be sleeved on the shaft core 2 through a number of adjustable guide rods 515 and adjustable guide blocks 516 and enter the card slot on the shaft core 2 under the action of the internal circlip installation mechanism 61.

[0047] Combined with the attached Figure 6 and the attached Figure 7 and the attached Figure 8 As shown in:

[0048] The internal circlip installation mechanism 61 includes a push rod 611 sleeved outside the circlip guiding rod 511. A sleeve 613 is provided at the bottom end of the push rod 611, and a first push block 612 is provided at the top end. A number of first pushing members 614 for pushing the installation of the internal circlip are provided on the sleeve 613;

[0049] The driving member 1, i.e., 614, includes a first sliding rod 615 inserted into the side wall at the bottom end of the sleeve 613. One end of the first sliding rod 615 is provided with a second contact plate 616 that contacts both the adjustable guide block 516 and the inner circlip. A first spring 618 sleeved outside the first sliding rod 615 is arranged between the second contact plate 616 and the side wall of the sleeve 613. The other end of the first sliding rod 615 is provided with a limiting plate 617 located outside the sleeve 613;

[0050] The outer circlip installation mechanism 71 includes a connection block 711 fixedly sleeved outside the push rod 611. The bottom end of the connection block 711 is provided with a connection cylinder 712. The bottom end of the connection cylinder 712 is provided with a plurality of convex members 713 with hollow interiors. Two of the plurality of convex members 713 form a group. A second driving member 714 capable of pushing the installation of the outer circlip is arranged between the two convex members 713 in a group. A sliding block 724 is slidably sleeved outside the push rod 611, and the sliding block 724 contacts the top ends of the plurality of second driving members 714;

[0051] The second driving member 714 includes a central cylinder 715 located between the two convex members 713 in a group. Chute grooves are provided at corresponding positions on the opposite facing surfaces of the two convex members 713 in a group. Telescopic rods 716 capable of telescoping and with ends located in the chute grooves are arranged at both ends of the central cylinder 715. The ends of the telescopic rods 716 are provided with sliding plates 717 slidably connected to the chute grooves. A second sliding rod 718 located inside the convex member 713 is slidably inserted into the sliding plate 717. One end of the second sliding rod 718 is provided with a first limiting block 719, and the other end passes through the sliding plate 717 and the end is provided with a second limiting block 721 contacting the outer circlip. A second spring 720 sleeved outside the second sliding rod 718 is arranged between the first limiting block 719 and the sliding plate 717. The first limiting block 719 is driven by the sliding block 724 through a transmission member;

[0052] The transmission member includes a plurality of transmission rods 722 respectively connected to the plurality of first limiting blocks 719. The ends of the transmission rods 722 are provided with folding rods 723 extending inwards and with tops contacting the sliding block 724. A plurality of sliding connection frames 725 are provided at the bottom end of the sliding block 724, and the tops of the folding rods 723 are located inside the sliding connection frames 725 and are slidably connected to the sliding connection frames 725.

[0053] After adjusting the inner circlip guiding member mechanism 51 and the outer circlip guiding member mechanism 41, the inner circlip and the outer circlip are simultaneously placed inside the cylinder body 211. Since the circlips need to be clamped in the card slots, that is, at this time the circlips cannot automatically enter the card slots. At this time, the inner circlip is located on the adjustable guide rod 515 and the outer circlip is located on the contraction guide block 415. At this time, the inner circlip installation mechanism 61 and the outer circlip installation mechanism 71 can install the inner and outer circlips into the predetermined card slots simultaneously;

[0054] The working principles of the inner circlip installation mechanism 61 and the outer circlip installation mechanism 71: Place the inner circlip installation mechanism 61 and the outer circlip installation mechanism 71 as shown in the appendix Figure 3Assemble as shown, and insert the assembled inner circlip installation mechanism 61 and the outer circlip installation mechanism 71 into the cylinder body 211. In this application, all the convex parts 713 are in close contact with the inner wall of the cylinder body 211, that is, both the inner circlip installation mechanism 61 and the outer circlip installation mechanism 71 are located at the axis of the cylinder body 211;

[0055] During the process, the push rod 611 and the sleeve 613 are sleeved outside the inner circlip guide mechanism 51. During the movement of the sleeve 613 towards the cylinder body 211, the contact plate two 616 on the pushing part one 614 moves along the adjustable guide rod 515 and the adjustable guide block 516. When the contact plate two 616 contacts the inner circlip, it will push the inner circlip towards the shaft core 2. During this process, the inner circlip 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. Since 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, that is, the contact plate two 616 will push the inner circlip to the shaft core 2 through the adjustable guide rod 515 and the adjustable guide block 516. At this time, continuing to push the push rod 611 can move the inner circlip to the slot on the shaft core 2;

[0056] When operating the inner circlip installation mechanism 61, the outer circlip installation mechanism 71 will move simultaneously. When the convex part 713 contacts the outer circlip, the outer circlip will be located between the convex part 713 and the contraction guide block 415. When continuing to push the push rod 611, the outer circlip will reduce its opening under the action of the inner end face of the contraction guide block 415 to gradually match the inner diameter of the shaft sleeve 1. When the convex part 713 contacts the shaft sleeve 1, the outer circlip is just located at the mouth of the shaft sleeve 1 and the opening size is just large enough to enter the shaft sleeve 1. And at this time, the inner circlip has been installed in place. Then, by manually adjusting the folding rod 723 on the pushing part two 714, the folding rod 723 drives the sliding plate 717 to move on the convex part 713 through the transmission rod 722, so that the limiting block two 721 can contact the outer circlip. When the sliding plate 717 moves, it drives the other sliding plate 717 to move synchronously through the central cylinder 715 and the contraction rod 716. The staff needs to manually adjust the pushing part two 714 on the three groups of convex parts 713 so that all the limiting blocks two 721 are in contact with the outer circlip. Then, manually push the pushing part two 714 through the sliding block 724, so that the limiting block two 721 drives the outer circlip to move into the shaft sleeve 1 and install it into the inner slot of the shaft sleeve 1.

[0057] A number of the contraction guide blocks 415 and a number of the convex parts 713 are arranged alternately, and a number of the adjustable guide blocks 516 and a number of the contraction guide blocks 415 are arranged alternately;

[0058] A through slot one 619 penetrating the bottom end of the sleeve 613 is jointly arranged at the side ends of the sleeve 613 and the push rod 611, and a through slot two 726 penetrating the bottom end of the connecting cylinder 712 is arranged at the side end of the connecting cylinder 712. The fixed connecting rod 4 passes through the through slot one 619 and the through slot two 726.

[0059] Specific implementation manner: When using the quick installation tooling for earless circlips provided by the present invention to install earless circlips:

[0060] When installing the earless circlip, the bushing 1 needs to be placed vertically on the workbench, and the shaft core 2 and the bearing body 3 are placed in the bushing 1. The placement cylinder 21 and the bushing 1 are accurately docked through the docking mechanism 31, and the outer circlip guiding mechanism 41 and the inner circlip guiding mechanism 51 are adjusted to change the opening during the installation of the inner and outer circlips. The inner and outer circlips are simultaneously placed in the placement cylinder 21, and then the inner circlip installation mechanism 61 and the outer circlip installation mechanism 71 are used to simultaneously push the inner and outer circlips into the card slots on the bushing 1 and the shaft core 2.

[0061] When installing earless circlips of different specifications, only the outer circlip guiding mechanism 41 and the inner circlip guiding mechanism 51 need to be adjusted, and then the inner circlip installation mechanism 61 and the outer circlip installation mechanism 71 can be directly used to install the inner and outer circlips.
