Description

Technical Field

[0001] This utility model relates to a device for assembling retaining rings in ball joint components. Background Technology

[0002] As a key connecting component in mechanical transmission, the ball joint assembly is both structurally precise and functionally important. It mainly consists of a ball head, a ball socket, a bearing outer ring, and a connecting shaft. The ball head and ball socket achieve multi-angle rotation through an arc-shaped contact surface, while the bearing outer ring serves to fix and protect the internal structure. The connecting shaft is used to connect with other mechanical components to ensure the effective transmission of power or motion.

[0003] Dust covers play an indispensable role in ball joint assemblies. Their main function is to prevent external impurities such as wind, sand, rain, and dust from entering the ball joint assembly, thus avoiding wear on the contact surfaces of the ball joint and socket. They also prevent moisture corrosion that could cause rust, thereby extending the service life of the ball joint assembly and ensuring its transmission accuracy and stability. Dust covers are typically made of rubber or plastic with a certain degree of elasticity and wear resistance. They have a cylindrical structure, with an interface at one end that matches the outer contour of the ball joint assembly, and the other end is closed or semi-closed with a smooth inner wall for easy insertion.

[0004] Currently, when fitting dust covers, the general method is to slip them on from top to bottom. However, the top opening is relatively narrow or closed, and dust covers are usually made of soft materials such as rubber, making it difficult and time-consuming to press them on from the bottom. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art, thereby providing a device for assembling retaining rings for ball joint components that is easy to process and can be accurately fitted.

[0006] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0007] The present invention relates to a device for assembling retaining rings for ball joint components, comprising a main moving mechanism 1 and a worktable vertically penetrated by the main moving mechanism 1; an upper pressing mechanism and a gripping mechanism are respectively provided at the upper and lower ends of the main moving mechanism; the gripping mechanism includes a fixed plate b and a cylinder e located below the fixed plate b, wherein the piston rod in the cylinder e extends upward through the fixed plate b, and connecting blocks arranged vertically side by side are sleeved on the top of the piston rod, the connecting blocks being gear-shaped, and gripping clamps are respectively provided on the connecting blocks.

[0008] Preferably, the gripper has an elongated opening that slopes downwards, and a connecting pin that passes through the elongated opening is provided laterally on the elongated opening.

[0009] Preferably, the pressing mechanism is used to press down on the workpiece to be processed, including a support plate a and a fixed plate a below the support plate a; a cylinder c is provided on the support plate a, and the piston rod of the cylinder c passes through the support plate a and is connected to the fixed plate a; guide posts passing through the support plate a are symmetrically provided on both sides of the fixed plate a to guide the fixed plate a when it moves up and down; a cylinder d is also provided in the middle of the fixed plate a, and a top post is provided at the end of the cylinder d.

[0010] Preferably, the top column is composed of four separable metal plates, with locking holes formed at the contact positions of the metal plates connected in pairs, and locking blocks are provided on the piston rod of cylinder d to be inserted into the locking holes; an inner push rod is provided at the end of the piston rod of cylinder d, and a support head is provided at the end of the inner push rod.

[0011] Preferably, the main moving mechanism includes a support column, with two symmetrical guide rails a on the inner side of the upper end of the support column; a guide rail b is provided at the middle position of the inner side of the support column; a slider is provided on the guide rail a, a sliding plate is provided on the guide rail b, and fixing blocks are provided on both sides of the guide rail b to fix the worktable in the middle of the support column.

[0012] Preferably, the slider is connected to the support plate a, and the slide plate is connected to the fixed plate b.

[0013] Preferably, a fixing plate is provided at the top of the support column, and a cylinder a is provided at the front end of the fixing plate; a cylinder b is provided on the inner side of the lower end of the support column, and a limit member is provided at the end of the guide rail b.

[0014] Preferably, a tooling is provided on the worktable directly below the pressing mechanism.

[0015] Preferably, the tooling is a circular boss, including a main body and a circular recessed platform that is recessed downward in the middle of the main body; and has a plurality of slots evenly arranged in a circular pattern; and has a transverse groove in the middle position.

[0016] The beneficial effects of this utility model are:

[0017] Because the dust cover is wider at the bottom and narrower at the top when it is installed, it is difficult to install it by pressing it down from above using a tool. In this application, the clamp is set at the bottom and can be unfolded from the inside out. When the unfolded clamp opens the lower opening of the dust cover, the dust cover is temporarily fixed to the clamp. Then the clamp moves down and the dust cover is also pushed down. Afterwards, the clamp tightens and releases the dust cover, making the installation of the dust cover convenient and accurate. Attached Figure Description

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0024] like Figure 1 , 2 , Figure 6 As shown, the device for assembling retaining rings in ball joint components is mainly used to seal and prevent dust from the rubber dust cover on the ball joint head and ball cup. However, one end of the dust cover has a fastening ring, which makes it relatively troublesome to install the dust cover.

[0025] The device includes a main moving mechanism 1 and a worktable 2 that is vertically penetrated by the main moving mechanism 1. An upper pressing mechanism 3 and a gripping mechanism 4 are respectively provided at the upper and lower ends of the main moving mechanism 1. The gripping mechanism 4 includes a fixed plate b4.2 and a cylinder e4.3 located below the fixed plate b4.2. The piston rod of the cylinder e4.3 (it should be noted that those skilled in the art know the structure of a cylinder, and the piston rod in a cylinder is prior art; therefore, the structure of the cylinder and the piston rod are not described in detail in this application) extends upward through the fixed plate b4.2. Connecting blocks 4.4 arranged vertically side-by-side are fitted on the top of the piston rod. The connecting blocks 4.4 are gear-shaped, and grippers 4.1 are respectively provided on the connecting blocks 4.4. More specifically, a gripper 4.1 is provided at each pair of openings of the gear-shaped connecting blocks 4.4, while the lower connecting block 4.4 is located on the fixed plate b4.2, and the ends of the grippers 4.1 are rotatably fixed to the lower connecting block 4.4.

[0026] The device also includes a conical kit 7, which is a matching tool. During operation, the dust cover A is first placed on the kit 7.

[0027] The gripper 4.1 has an elongated, downward-sloping opening 4.5, and a connecting pin 4.6 is horizontally arranged through the elongated opening 4.5. Specifically, the elongated opening 4.5 corresponds to the upper connecting block 4.4, and the connecting pin 4.6 passes through the two openings of the upper connecting block 4.4. When the cylinder e4.3 acts downward, the connecting pin 4.6 moves downward along the elongated opening 4.5, causing the gripper 4.1 to open. Because the elongated opening 4.5 is inclined downward, when the connecting pin 4.6 is at the top of the elongated opening 4.5, the diameter between the grippers 4.1 is smaller than when the connecting pin 4.6 is at the end of the elongated opening 4.5. As the connecting pin 4.6 slides downward, the grippers 4.1 will slowly open. The end of the gripper 4.1 is also connected to the lower connecting block by a horizontal pin, allowing the end of the gripper 4.1 to rotate at a certain angle, rather than being fixed.

[0028] See Figure 3-4 As shown, the upper pressing mechanism 3 is used to press down on the workpiece to be processed. (See reference...) Figure 8A is a dust cover, and B is a fastening ring. During processing, the fastening ring B is first put on the dust cover A, and then the dust cover A is placed on the ball joint assembly. The upper pressing mechanism 3 presses down on the dust cover A and the ball joint assembly. The gripper 4.1 penetrates into the dust cover A from bottom to top. After the gripper 4.1 opens, it opens the port of the rubber dust cover. When the gripper 4.1 moves downward, it will drive the dust cover A to be put on the ball joint assembly and can also drive the fastening ring B to be locked in. Regarding the fastening ring B, the applicant should explain that those skilled in the art know that the fastening ring B here is an open-wound iron wire, that is, the two ends of the iron wire are not fixed. When putting on the dust cover A, the fastening ring B can be stretched appropriately, and after being locked in, it can return to its original position. The tolerances are all calculated. Therefore, when the gripper 4.1 assists in putting on the dust cover A, the fastening ring B will not cause any obstruction.

[0029] The pressing mechanism 3 includes a support plate a3.1 and a fixed plate a3.4 below the support plate a3.1. A cylinder c3.2 is installed on the support plate a3.1, and the piston rod of the cylinder c3.2 passes through the support plate a3.1 and connects to the fixed plate a3.4, so that the cylinder c3.2 can realize the up and down movement of the fixed plate a3.4. Guide posts 3.8 are symmetrically arranged on both sides of the fixed plate a3.4, passing through the support plate a3.1, to guide the fixed plate a3.4 when it moves up and down. A cylinder d3.3 is also installed in the middle of the fixed plate a3.4, and a top post 3.6 is installed at the end of the cylinder d3.3 to directly press on the ball joint assembly, so as to facilitate the installation of the dust cover A.

[0030] The top post 3.6 is composed of four separable metal plates. A locking hole 3.7 is formed at the contact point of each pair of connected metal plates. A locking block 3.5 is provided on the piston rod of cylinder d3.3, corresponding to and engaging with the locking hole 3.7, thus limiting the movement of the piston rod of cylinder d3.3. An inner push rod 3.9 is provided at the end of the piston rod of cylinder d3.3, and a support head 3.10 is provided at the end of the inner push rod 3.9. Specifically, when the piston rod of cylinder d3.3 moves downward, the locking block 3.5 also moves downward within the locking hole 3.7, and is limited by the locking hole 3.7, fixing the downward movement distance of the inner push rod 3.9. The support head 3.10 can then press down against the end of the top post 3.6, thus, under the pressure of the support head 3.10, the four metal plates of the top post 3.6 are opened apart.

[0031] See Figure 5As shown, the main moving mechanism 1 includes a support column 1.1, with two symmetrical guide rails a1.4 arranged on the inner side of the upper end of the support column 1.1; a guide rail b1.6 is arranged at the middle position of the inner side of the support column 1.1; a slider 1.5 is arranged on the guide rail a1.4, and a sliding plate 1.7 is arranged on the guide rail b1.6; fixing blocks 6 are arranged on both sides of the guide rail b1.6 to fix the worktable 2 in the middle of the support column 1.1.

[0032] The slider 1.5 is connected to the support plate a3.1, and the slide plate 1.7 is connected to the fixed plate b4.2. In other words, the fixed plate b4.2 moves up and down on the guide rail b1.6 following the slide plate 1.7, which means that the gripping mechanism 4 moves up and down on the guide rail b1.6. The support plate a3.1 moves up and down on the guide rail a1.4 following the slider 1.5, which means that the pressing mechanism 3 moves on the guide rail a1.4.

[0033] A fixing plate 1.2 is provided at the top of the support column 1.1. A cylinder a1.3 is provided at the front end of the fixing plate 1.2. Specifically, the piston rod of the cylinder a1.3 is connected to the support plate a3.1, meaning that the cylinder a1.3 can control the support plate a3.1 to move up and down, thus controlling the overall up and down movement of the entire pressing mechanism. In conjunction with the cylinder c3.2, the fixing plate a3.4 is moved up and down, allowing for step-by-step height adjustment to ensure precision during height adjustment. Accuracy; A cylinder b1.9 is provided on the inner side of the lower end of the support column 1.1, and a limiter 1.8 is provided at the end of the guide rail b1.6. Specifically, the piston rod of the cylinder b1.9 is connected to the bottom of the fixed plate b4.2, so the cylinder b1.9 can control the overall up and down movement of the gripping mechanism 4, while the limiter 1.8 at the end of the guide rail b1.6 can abut against the bottom of the fixed plate b4.2 when the fixed plate b4.2 moves to the lowest position, ensuring that the fixed plate b4.2 will not continue to move downward.

[0034] See Figure 7 As shown, a tooling 5 is provided on the workbench 2 and directly below the pressing mechanism 3 for placing the ball joint assembly that needs to be covered with a dust cover A.

[0035] The tooling 5 is a circular boss, including a main body 5.1 and a circular recessed platform 5.2 that is recessed downward in the middle of the main body 5.1; and has a plurality of slots 5.3 evenly arranged in a circular pattern; and a horizontal groove 5.4 in the middle position for placing auxiliary tools during operation.

[0036] The beneficial effects of this utility model are:

[0037] Because the dust cover is wider at the bottom and narrower at the top when it is installed, it is difficult to install it by pressing it down from above using a tool. In this application, the clamp is set at the bottom and can be unfolded from the inside out. When the unfolded clamp opens the lower opening of the dust cover, the dust cover is temporarily fixed to the clamp. Then the clamp moves down and the dust cover is also pushed down. Afterwards, the clamp tightens and releases the dust cover, making the installation of the dust cover convenient and accurate.
