Description

Technical Field

[0001] This utility model relates to the technical field of sliding shaft retaining ring installation equipment, and in particular to a sliding shaft retaining ring installation device. Background Technology

[0002] A search revealed that existing technologies for installing sliding shaft retaining rings mostly rely on manual operation of clamps. Due to hand tremors and alignment deviations, installation accuracy is difficult to guarantee, and the retaining ring is prone to displacement or misalignment. The manual opening, adjustment, and installation steps are cumbersome, inefficient, and cannot meet the needs of mass production. During the operation, continuous force must be applied to maintain the retaining ring in an open state, which is labor-intensive and prone to fatigue damage. Furthermore, uneven manual opening force can easily lead to local overstretching deformation or even breakage of the retaining ring, resulting in a low yield. Therefore, a sliding shaft retaining ring installation device is provided to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to solve the problems mentioned in the background art by providing a sliding shaft retaining ring mounting device, which has the advantages of fine installation accuracy, good operational stability and high assembly efficiency, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sliding shaft retaining spring mounting device, comprising: an operating table, a first electric telescopic rod fixedly connected above the support of the operating table, an mounting plate provided below the support of the operating table, a retaining spring opening and mounting mechanism fixedly connected below the mounting plate, a sliding shaft clamp fixedly connected above the operating table and directly below the retaining spring opening and mounting mechanism, a sliding shaft to be installed provided above the sliding shaft clamp, and a retaining spring to be installed provided on the outside of the retaining spring opening and mounting mechanism.

[0005] As a further embodiment of this utility model: the retaining spring opening and mounting mechanism includes a mounting cylinder, three sets of second electric telescopic rods are fixedly connected to the side of the mounting cylinder, and a push spring ring claw is fixedly connected to the movable end of the second electric telescopic rod. Four sets of rotating grooves penetrating to the inner side are opened on the outer side of the mounting cylinder, and a set of retaining spring opening claws is rotatably connected to each set of rotating grooves. An anti-slip limiting block is fixedly connected to the side of the retaining spring opening claw. A connecting arm is rotatably connected to the side of the retaining spring opening claw near the mounting cylinder. All four sets of connecting arms are rotatably connected to the same set of central push connecting plates. A third electric telescopic rod is fixedly connected to the inner top wall of the mounting cylinder.

[0006] As a further improvement of this utility model, the movable end of the first electric telescopic rod passes through the operating table and is fixedly connected to the mounting plate.

[0007] As a further improvement of this utility model, the sliding shaft clamp is a three-jaw chuck.

[0008] As a further improvement of this utility model: the mounting cylinder is configured as a cylindrical shape with the opening facing downwards, and the end of the retaining spring opening claw is an outwardly extending arc design.

[0009] As a further improvement of this utility model: the push spring ring claw slides on the outside of the mounting cylinder, and the claw segment of the push spring ring claw is offset from the rotating groove to prevent the push spring ring claw from contacting and abutting with the snap ring claw.

[0010] As a further improvement of this utility model: the movable end of the third electric telescopic rod is fixedly connected to the upper end of the central push connecting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the coaxial alignment design of the sliding shaft clamp and the snap ring opening and installation mechanism, combined with the vertical lifting control of the first electric telescopic rod, ensures that the snap ring to be installed is accurately fitted into the slot of the sliding shaft, avoiding human operation errors. The four sets of snap ring opening claws achieve synchronous radial expansion through the connecting arm and the central push connecting plate. With the limiting effect of the anti-slip limit block, the snap ring expands evenly without slippage or deviation, avoiding deformation or falling off. At the same time, the coordinated control of the first, second, and third electric telescopic rods realizes the fully automated operation of snap ring opening, pushing, installation, and resetting, significantly improving installation efficiency and reducing manual labor intensity. The overall structural design combines high precision, stability, and high efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0020] Reference Figures 1 to 4 In this embodiment of the utility model, a sliding shaft retaining spring mounting device includes: an operating table 1, a first electric telescopic rod 2 fixedly connected above the support of the operating table 1, an mounting plate 3 provided below the support of the operating table 1, the movable end of the first electric telescopic rod 2 passing through the operating table 1 and fixedly connected to the mounting plate 3, a retaining spring opening mounting mechanism 4 fixedly connected below the mounting plate 3, a sliding shaft clamp 5 fixedly connected above the operating table 1 directly below the retaining spring opening mounting mechanism 4, the sliding shaft clamp 5 being a three-jaw chuck, a sliding shaft 6 to be installed being provided above the sliding shaft clamp 5, and a retaining spring 7 to be installed being provided outside the retaining spring opening mounting mechanism 4;

[0021] The first electric telescopic rod 2 drives the snap ring opening installation mechanism 4 to move vertically as a whole through the lifting installation plate 3. The sliding shaft clamp 5 clamps and fixes the sliding shaft 6 to be installed through the three-jaw chuck structure. When the snap ring opening installation mechanism 4 descends, it keeps coaxially aligned with the sliding shaft 6 to be installed. After the snap ring 7 to be installed completes radial expansion through the opening mechanism, it is accurately fitted into the slot position of the sliding shaft 6 to be installed.

[0022] The retaining spring opening and mounting mechanism 4 includes a mounting cylinder 41, which is a cylindrical shape with its opening facing downwards. The end of the retaining spring opening claw 45 has an outwardly extending arc design. Three sets of second electric telescopic rods 42 are fixedly connected to the side of the mounting cylinder 41. The movable end of the second electric telescopic rod 42 is fixedly connected to a push spring annular claw 43. Four sets of rotating grooves 44 are opened on the outer side of the mounting cylinder 41, extending to its inner side. Each set of rotating grooves 44 is rotatably connected to a set of retaining spring opening claws 45. The push spring annular claw 43 slides on the outer side of the mounting cylinder 41, and the claw segment of the push spring annular claw 43 is offset from the rotating groove 44. To prevent the push spring ring claw 43 from contacting and abutting with the snap spring opening claw 45, the snap spring opening claw 45 is fixedly connected to the side of the snap spring opening claw 45 with an anti-slip limit block 46 to prevent the snap spring 7 to be installed from sliding along the snap spring opening claw 45 when it is unfolded on the outside of the snap spring opening claw 45. The snap spring opening claw 45 is rotatably connected to the side of the snap spring opening claw 45 near the mounting cylinder 41 with a connecting arm 47. All four sets of connecting arms 47 are rotatably connected to the same set of middle push connecting plates 48. The inner top wall of the mounting cylinder 41 is fixedly connected to a third electric telescopic rod 49. The movable end of the third electric telescopic rod 49 is fixedly connected to the upper end of the middle push connecting plate 48.

[0023] The third electric telescopic rod 49 drives the four sets of connecting rotating arms 47 to rotate synchronously through the central push connecting plate 48, so that the four sets of snap ring opening claws 45 are radially expanded in the rotating groove 44. The anti-slip limit block 46 forms friction positioning with the inner wall of the snap ring. When the snap ring opening claw 45 is expanded to the set angle, the first electric telescopic rod 2 drives the push spring ring claw 43 to press down, pushing the expanded snap ring 7 to be installed from the outer end of the snap ring opening claw 45 to the outside of the sliding shaft 6 to be installed, accurately fitting it into the installation groove of the sliding shaft 6 to be installed. After the installation is completed, each telescopic rod resets to make the snap ring opening claw 45 close.

[0024] The working principle of this utility model is as follows: First, the sliding shaft 6 to be installed is clamped and fixed by the sliding shaft clamp 5 to ensure that its axis is coaxially aligned with the snap spring opening and installation mechanism 4.

[0025] The retaining ring 7 to be installed is sleeved on the outside of the retaining ring opening claw 45. The arc design at the end of the retaining ring opening claw 45 facilitates the guidance and positioning of the retaining ring and also makes it easier to push out the retaining ring 7 to be installed later. The anti-slip limiting block 46 blocks and restricts the retaining ring from sliding along the claw body.

[0026] The third electric telescopic rod 49 drives the middle push connecting plate 48 to move down, and through the four sets of connecting rotating arms 47, it synchronously drives the snap ring opening claw 45 to expand radially outward around the rotating groove 44, so that the snap ring 7 to be installed is evenly expanded to the preset diameter. The anti-slip limit block 46 prevents the snap ring 7 to be installed from sliding and stabilizes the snap ring position.

[0027] The first electric telescopic rod 2 drives the mounting plate 3 to press down the entire snap ring opening mounting mechanism 4. At the same time, the second electric telescopic rod 42 pushes the push spring ring claw 43 to move down along the outside of the mounting cylinder 41. The claw segment of the push spring ring claw 43 and the snap ring opening claw 45 are misaligned to avoid interference. The snap ring 7 to be installed is pushed away smoothly from the end of the snap ring opening claw 45, ensuring that the snap ring 7 to be installed is accurately fitted into the slot of the sliding shaft 6 to be installed.

[0028] After installation, the third electric telescopic rod 49 retracts, causing the retaining spring to open the claw 45 and retract to its original position. The second electric telescopic rod 42 retracts the push spring ring claw 43, and the first electric telescopic rod 2 raises the retaining spring to open the installation mechanism 4 to its initial position, completing one installation cycle.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
