Description
Technical Field
[0001] This utility model relates to the technical field of ball pin seats, and in particular to a cushioning and wear-resistant ball pin seat structure. Background Technology
[0002] A ball joint structure typically consists of a seat and corresponding mating parts. The seat has a specific shape, generally resembling a cup, cylinder, or block with a cavity. Its interior contains a space to accommodate the ball joint. The surface of this space often requires a certain degree of smoothness and appropriate dimensional accuracy to ensure a good fit with the ball joint. Functionally, ball joints are commonly used in applications requiring the transmission of force or torque while also demanding a certain degree of angular change and relatively flexible rotational capability at the connection points. For example, in automotive suspension systems, ball joints are frequently used to connect components such as control arms and steering knuckles. This allows the relevant components to flexibly change angles and transmit force when the wheels encounter bumps or steering during driving, ensuring stable and comfortable vehicle handling. Ball joints are also frequently used in the joints of some engineering machinery and the moving joints of robots to meet the requirements of flexible movement and force transmission under complex actions.
[0003] In existing technologies, the grinding ball pin seat is usually fixed in a corresponding position, the ball pin is fixed in a corresponding position, and the ball end is located inside the grinding ball pin seat. When rotating, the traditional ball pin seat usually does not have a buffer function. When subjected to compressive force, due to the lack of a buffer mechanism, the compressive force will be transmitted to the ball head almost directly. The ball head itself is usually a rigid structure. When subjected to a large compressive force instantaneously or repeatedly subjected to a certain degree of compressive force, it is easy for surface wear, deformation, or even cracks to occur between it and the ball head seat. Utility Model Content
[0004] To overcome the technical defects of the existing technology, this utility model provides a buffer wear-resistant ball pin seat structure, which can effectively buffer the ball pin body under vertical force and collisions caused when rotating to extreme angles, reduce the damage to the ball pin seat body and ball pin body caused by rigid impact and excessive impact force, and improve the reliability of the structure under complex stress conditions.
[0005] The technical solution adopted by this utility model is as follows: it includes a ball pin seat body, the inner wall of the ball pin seat body is provided with a ball pin body, a buffer groove is opened on the lower side of the inner wall of the ball pin seat body, a hollow groove block is fixedly connected to the lower side of the inner wall of the buffer groove, a pressure block is slidably fitted on the inner wall of the hollow groove block, an arc-shaped support is fixedly connected to the upper side of the pressure block, and a reset mechanism is provided on the lower side of the ball pin seat body.
[0006] An oil seal plate is provided on the upper side of the ball pin seat body, and the oil seal plate slides in fit with the ball pin body. A buffer assembly that cooperates with the ball pin body is provided on the upper side of the ball pin seat body, and a discharge hole is opened on one side of the empty slot block.
[0007] Preferably, the reset mechanism includes an inspection port opened on the lower side of the ball pin seat body, a sealing bolt threaded into the inner wall of the inspection port, and a reset spring fixedly connected to the sealing bolt.
[0008] Preferably, the buffer assembly includes an impact frame fixedly connected to the upper side of the oil seal plate and a buffer sleeve fixedly connected to the ball pin body, wherein the buffer sleeve and the impact frame cooperate with each other.
[0009] Preferably, a mounting base is fixedly connected to the lower side of the ball pin seat body, and a connection hole is provided on the upper side of the mounting base.
[0010] Preferably, a plurality of buffer pads are provided on the lower side of the inner wall of the ball pin seat body, and the plurality of buffer pads cooperate with the arc-shaped support.
[0011] Preferably, the oil seal plate is provided with a plurality of connecting screws, which are fixed to the ball pin seat body.
[0012] Preferably, a soft dust cover is fixedly connected to the upper side of the impact frame, and the soft dust cover is fixed to the ball pin body.
[0013] Preferably, the oil seal plate and the ball pin body are fixedly connected by a soft sealing cloth.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model, through the structure consisting of a buffer groove, a pressure block, an arc-shaped support, and a return spring, as well as the cooperation between the buffer sleeve and the impact frame in the buffer assembly, can effectively buffer the ball pin body under vertical force (including vertical impact force) and collisions caused when rotating to extreme angles. This reduces damage to the ball pin seat body and the ball pin body caused by rigid impacts and excessive impact force, and improves the reliability of the structure under complex stress conditions.
[0016] 2. This utility model, through the buffer groove and discharge hole, allows lubricating oil to be injected into the buffer groove. When the pressure block is squeezed inside the empty groove block, the lubricating oil in the empty groove block is squeezed into the buffer groove through the discharge hole. This causes the lubricating oil inside the buffer groove to move upward, thereby coating the outer side of the ball pin body. This provides lubrication after impact, reducing wear during rotation and further improving service life. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:
[0024] like Figure 1-5 As shown, the embodiment provides a buffer wear-resistant ball pin seat structure, including a ball pin seat body 1, a ball pin body 2 provided on the inner wall of the ball pin seat body 1, a buffer groove 3 opened on the lower side of the inner wall of the ball pin seat body 1, a hollow groove block 15 fixedly connected to the lower side of the inner wall of the buffer groove 3, a pressure block 4 slidably fitted on the inner wall of the hollow groove block 15, an arc-shaped support 5 fixedly connected to the upper side of the pressure block 4, and a reset mechanism 6 provided on the lower side of the ball pin seat body 1.
[0025] A mounting base 10 is fixedly connected to the lower side of the ball pin seat body 1. A connecting hole 11 is provided on the upper side of the mounting base 10. When the ball pin seat is installed on the corresponding equipment or structure, the connecting hole 11 can play a precise positioning role. The ball pin seat can be fixedly installed by inserting a suitable connector into the connecting hole 11.
[0026] Multiple buffer pads 12 are provided on the lower side of the inner wall of the ball pin seat body 1. The multiple buffer pads 12 cooperate with the arc-shaped support 5. When the ball pin body 2 is subjected to external force, whether it is the pressure in the vertical direction or the component force in other directions, the ball pin body 2 will be displaced, which will drive the arc-shaped support 5 to press down or move. The buffer pads 12 and the arc-shaped support 5 cooperate with each other to buffer the impact force transmitted from the ball pin body 2, adding a buffer mechanism and further improving the buffering effect.
[0027] An oil seal plate 7 is provided on the upper side of the ball pin seat body 1. The oil seal plate 7 and the ball pin body 2 are in sliding fit. A buffer assembly 8 that cooperates with the ball pin body 2 is provided on the upper side of the ball pin seat body 1. A discharge hole 9 is opened on one side of the empty slot block 15.
[0028] The reset mechanism 6 includes an inspection port 601 located on the lower side of the ball pin seat body 1, a sealing bolt 602 threaded into the inner wall of the inspection port 601, and a reset spring 603 fixedly connected to the sealing bolt 602. The reset spring 603 converts mechanical energy into elastic potential energy through elastic deformation, stores the energy of external impact, and thus reduces the instantaneous load borne by the ball pin seat body 1.
[0029] A soft dust cover 14 is fixedly connected to the upper side of the impact frame 801. The soft dust cover 14 is fixed to the ball pin body 2. By being fixed to the ball pin body 2, the soft dust cover 14 can form an effective protective barrier in the upper area of the ball pin seat, blocking external dust, sand and other small particles from entering the ball pin seat. This prevents these impurities from entering the contact area between the ball pin body 2 and the ball pin seat body 1, avoiding them from acting as abrasives during relative movement and aggravating wear. This ensures the cleanliness of the internal structure of the ball pin seat and extends its service life.
[0030] The buffer assembly 8 includes an impact frame 801 fixedly connected to the upper side of the oil seal plate 7 and a buffer sleeve 802 fixedly connected to the ball pin body 2. The buffer sleeve 802 and the impact frame 801 cooperate with each other. When the ball pin body 2 is rotated, when the rotation reaches the most extreme, the buffer sleeve 802 will contact the impact frame 801, which can realize instantaneous rigid collision during large-angle rotation, thereby achieving buffering and further improving the buffering effect.
[0031] The oil seal plate 7 is provided with multiple connecting screws 13, which are fixed to the ball pin seat body 1. The oil seal plate 7 can be easily fixed by the connecting screws 13, and similarly, the oil seal plate 7 can be easily disassembled by the connecting screws 13.
[0032] A soft sealing cloth 16 is fixedly connected to the oil seal plate 7 and the ball pin body 2. The soft sealing cloth 16 is placed between the oil seal plate 7 and the ball pin body 2. It will not affect the rotation of the ball pin body 2, and at the same time, it can seal the lubricating oil inside the ball pin seat body 1 to prevent it from flowing out from the inside of the ball pin seat body 1 after being impacted.
[0033] The implementation principle of a buffer wear-resistant ball pin seat structure in this application embodiment is as follows: When the ball pin body 2 is subjected to a downward force, it will press down on the arc-shaped support 5. The arc-shaped support 5 drives the pressure block 4 to slide down along the inner wall of the empty groove block 15. During this process, since the buffer groove 3 provides a certain space, the downward pressing action of the ball pin body 2 has a buffer margin. When the pressure block 4 slides in the empty groove block 15, it will squeeze the reset spring 603 in the reset mechanism 6. The reset spring 603 undergoes elastic deformation under force, storing part of the energy of the ball pin body 2 pressing down in the form of elastic potential energy. When the external force decreases or disappears, the reset spring 603... Relying on its own elastic restoring force, the pressure block 4 and the arc-shaped support 5 are pushed upward, so that the ball pin body 2 returns to its original relatively suitable position, playing a role in buffering and supporting reset. At the same time, the multiple buffer pads 12 set on the lower side of the inner wall of the ball pin seat body 1 can also assist in buffering, further reducing the impact force of the ball pin body 2 on the ball pin seat. In conjunction with the arc-shaped support 5, the position of the ball pin body 2 is better stabilized, reducing wear and deformation problems caused by excessive impact force between the ball pin body 2 and the ball pin seat body 1, extending the overall service life of the ball pin seat, improving its reliability under complex stress conditions, and ensuring the stable operation of related equipment.
[0034] By injecting lubricating oil into the buffer groove 3, when the pressure block 4 is squeezed inside the empty groove block 15, the lubricating oil in the empty groove block 15 will be squeezed into the buffer groove 3 from the discharge hole 9, causing the lubricating oil inside the buffer groove 3 to move upward, thereby coating the outside of the ball pin body 2, so as to achieve lubrication after being impacted, thereby reducing its wear and further improving its service life.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
