Abstract
Description
[Technical Field]
[0001] This utility model relates to the technical field of ball joint mounting equipment for rocker arm assemblies, and in particular to a pre-compression riveting device for rocker arm assemblies with the ball joint facing upwards. [Background Technology]
[0002] In automotive suspension systems, the ball joint assembly, as a core force-transmitting component connecting the wheels and the chassis, directly determines the steering system's sensitivity and driving stability through its assembly precision. Traditional riveting processes employ a split workstation layout: at the lubrication station, lubricant is applied to the inner wall of the ball joint using a brush or spray nozzle. The operator then manually transfers the workpiece to the pre-pressing station, where a hydraulic cylinder drives a conical press head to force the ball joint into the ball joint. After pressing, the worker must move the workpiece a second time to the dust cover assembly area, where a ring clamp presses the rubber dust cover into the ball joint's neck groove. Finally, the orientation of the riveting surface is manually adjusted, and the assembly is positioned below the riveting machine for final riveting.
[0003] This discrete processing mode has significant mechanical defects: the transfer of workpieces between processes depends entirely on manual gripping and positioning, which not only increases labor intensity due to repeated handling, but also causes cumulative positioning errors due to multiple clamping; there is a lack of physical linkage mechanism between functional units, and the process cycle is constrained by the speed of personnel operation, making it impossible to form a continuous processing flow. [Utility Model Content]
[0004] The purpose of this invention is to solve the problems in the prior art by proposing a pre-press riveting device with the ball head facing upward for the swing arm assembly, which can rivet the ball seat.
[0005] To achieve the above objectives, this utility model proposes a pre-compression riveting device for a swing arm assembly with the ball end facing upwards, comprising: a base, a bracket mounted on the base, an oiling mechanism mounted on the base, a pre-compression mechanism mounted on the base, a dust cover pressing mechanism mounted on the base, and a riveting mechanism mounted on the base.
[0006] The bracket is located between the pre-compression mechanism and the oiling mechanism on the base. A sliding seat is slidably connected to the bracket, and a pneumatic clamping robot is slidably connected to the sliding seat. The pneumatic clamping robot is aligned with the workpiece.
[0007] A displacement seat is slidably connected to the base, and a horizontally arranged support seat and a dust cover are fixedly connected to the displacement seat.
[0008] Preferably, the oiling mechanism includes a rotating disk rotatably connected to the base and a connecting seat 1 slidably connected to the base under inclined conditions. A copper tube is fixedly connected to the connecting seat 1, the copper tube is aligned with the rotating disk, and one end of the copper tube can be close to the rotating disk. The pre-pressing mechanism and the dust cover pressing mechanism are located on one side of the rotating disk.
[0009] Preferably, the pre-compression mechanism includes a pneumatic clamping cylinder, which is vertically driven and slidably connected to the base. The pneumatic clamping cylinder is arranged opposite to the rotating disk and is used to drive the ball head to press into the ball seat. The pre-compression mechanism is located on one side of the pneumatic clamping cylinder.
[0010] Preferably, the pre-compression mechanism includes a lifting seat, a clamping robot, and a pressure head. The lifting seat is flexibly connected to the base, the clamping robot is fixedly connected to the lifting seat, and the pressure head is flexibly connected to the base.
[0011] Preferably, the riveting mechanism includes a lifting block, a rotating cylinder, and a riveting disc. The lifting block is vertically connected to the base, the rotating cylinder is rotatably connected to the bottom of the lifting block, and the riveting disc is fixedly connected to the rotating cylinder.
[0012] Preferably, the riveting disc is provided with an inclined surface.
[0013] Preferably, a sliding rod is fixedly connected to the bracket, and the sliding rod is slidably connected to the sliding seat.
[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: By integrating the oiling mechanism, pre-pressing mechanism, dust cover pressing mechanism, and riveting mechanism into the base, the spatial isolation of traditional separate workstations is eliminated. The pneumatic clamping robot and sliding seat work together to achieve automatic workpiece transfer, reducing the loss of positioning references caused by manual handling and ensuring the axial alignment of the ball head, ball seat, and dust cover. The slide rail system of the bracket, combined with the lifting function of the pneumatic clamping robot, keeps the workpiece in a single clamping state during the oiling, pressing, and dust cover assembly processes. The lateral sliding structure of the displacement seat and support seat enables precise positioning of the workpiece in the riveting station, reducing the cumulative error caused by multiple clamping operations.

[0026] like Figures 1 to 5The ball head facing upward pre-press riveting device for the swing arm assembly includes: a base 1, a bracket 2 mounted on the base 1, an oiling mechanism 3 mounted on the base 1, a pre-pressing mechanism 4 mounted on the base 1, a dust cover pressing mechanism 5 mounted on the base 1, and a riveting mechanism 6 mounted on the base 1. The oiling mechanism 3 is mainly used to apply oil to the ball seat, the pre-pressing mechanism 4 is mainly used to pre-press the ball head, the dust cover pressing mechanism 5 is mainly used to pre-press the dust cover onto the ball seat, and the riveting mechanism 6 is mainly used to rivet the ball seat.
[0027] Since the support 2 is located between the pre-pressing mechanism 4 and the oiling mechanism 3 on the base 1, a sliding seat 7 is slidably connected to the support 2. A sliding rod 22 is fixedly connected to the support 2, and the sliding rod 22 is slidably connected to the sliding seat 7. A pneumatic clamping robot 8 is slidably connected to the sliding seat 7. The pneumatic clamping robot 8 is aligned with the workpiece. Therefore, after the oiling mechanism 3 finishes oiling the base 1, the pneumatic clamping robot 8 is activated. After the pneumatic clamping robot 8 clamps the base 1, it moves up and down, causing the base to disengage from the oiling mechanism 3. The pneumatic clamping robot 8 is driven by a cylinder, which is fixedly connected to the sliding seat 7, and its output shaft is fixedly connected to the pneumatic clamping robot 8, thus realizing the lifting and lowering of the pneumatic clamping robot 8. After the pneumatic clamping robot 8 rises, the sliding seat 7 moves. The sliding seat 7 is driven by a cylinder, which is fixedly connected to the base 1, and its output shaft is fixedly connected to the sliding seat 7. The sliding seat 7 can be moved. Once the sliding seat 7 moves, the displacement seat 9 is laterally slidably connected to the base 1. The displacement seat 9 is fixedly connected to the horizontally arranged support seat 10 and the dust cover seat 11. Since the sliding seat 7 will indirectly drive the ball seat to move to the support seat 10, the operator puts the ball head into the ball seat and uses the pre-pressing device to press the ball head into the ball seat, thereby realizing the installation of the ball head and the ball seat. Once the ball seat and the ball head are pressed, the displacement seat 9 moves. The displacement seat 9 is driven by a cylinder, which is fixedly connected to the base 1 and the output shaft is fixedly connected to the displacement seat 9. This allows the displacement seat 9 to drive the ball seat to move into the dust cover pressing mechanism 5. The dust cover pressing mechanism 5 presses the dust cover into the ball seat, thereby realizing the installation of the dust cover. After the dust cover is installed, the displacement seat 9 continues to move, causing the ball seat to move into the riveting device. The riveting device rivets the ball seat, thereby realizing the installation of the ball head and the ball seat.
[0028] Specifically, the oiling mechanism 3 includes a rotating disk 12 rotatably connected to the base 1 and a connecting seat 13 slidably connected to the base 1. A copper pipe 14 is fixedly connected to the connecting seat 13. The copper pipe 14 is aligned with the rotating disk 12, and one end of the copper pipe 14 can be close to the rotating disk 12. The pre-pressing mechanism 4 and the dust cover pressing mechanism 5 are located on one side of the rotating disk 12. The rotating disk 12 is used to support the ball seat. The rotating disk 12 is driven by a motor, which is fixedly connected to the base 1, and the output shaft is fixedly connected to the rotating disk 12. This allows the rotating disk 12 to drive the ball seat to rotate. Once the ball seat rotates, the connecting seat 13, driven by a cylinder, moves. The cylinder is fixedly connected to the base 1, and one end is fixedly connected to the connecting seat 13. This allows the connecting seat 13 to drive the copper pipe 14 to approach the ball seat, and external lubricating oil is transmitted to the ball seat through the copper pipe 14, thereby achieving oiling of the ball seat.
[0029] Specifically, the pre-pressing mechanism 4 includes a pneumatic clamping cylinder 15, which is vertically driven and slidably connected to the base 1. The pneumatic clamping cylinder 15 is arranged opposite to the rotating disk 12 and is used to drive the ball head to press into the ball seat. The pre-pressing mechanism 4 is located on one side of the air cylinder clamping cylinder. The pneumatic clamping cylinder 15 is pneumatically driven, and the cylinder is fixedly connected to the base 1, with one end fixedly connected to the pneumatic clamping cylinder 15. This allows the air cylinder clamping cylinder to drive the air cylinder held by the pneumatic clamping cylinder 15 to press into the ball seat, thereby realizing the installation of the ball seat and the ball head.
[0030] Specifically, the pre-compression mechanism 4 includes a lifting seat 16, a clamping robot 17, and a pressure head 18. The lifting seat 16 is flexibly connected to the base 1, the clamping robot 17 is fixedly connected to the lifting seat 16, and the pressure head 18 is flexibly connected to the base 1. The lifting seat 16 is driven by a cylinder, which is fixedly connected to the base 1, and its output shaft is fixedly connected to the lifting seat 16, thus enabling the lifting seat 16 to rise and fall. Once the lifting seat 16 descends, it will drive the clamping robot 17 to approach the anti-collision device on the support base 10. When the gripping robot 17 approaches the dust cover, it grips the dust cover and the lifting seat 16 raises and lowers the dust cover to disengage it from the support seat 10. At this time, the displacement seat 9 moves, causing the dust cover seat 11 to move below the dust cover. The gripping robot 17 releases the dust cover and places it onto the ball seat. Then, the pressure head 18, driven by a cylinder, descends. The cylinder is fixedly connected to the base 1, and the output shaft is fixedly connected to the pressure head 18. This allows the pressure head 18 to press the dust cover into the ball seat, thus completing the installation of the dust cover.
[0031] Specifically, the riveting mechanism 6 includes a lifting block 19, a rotating cylinder 20, and a riveting disc 21. The lifting block 19 is flexibly connected to the base 1, the rotating cylinder 20 is rotatably connected to the bottom of the lifting block 19, and the riveting disc 21 is fixedly connected to the rotating cylinder 20. The lifting block 19 is driven by a cylinder, which is fixedly connected to the base 1 and has one end fixedly connected to the lifting block 19. This allows the lifting block 19 to rise and fall. Once the lifting block 19 rises and falls, it will cause the rotating cylinder 20, driven by a motor, to descend, causing the rotating cylinder 20 to bring the riveting disc 21 into contact with the ball seat. The rotating cylinder 20 is driven by a motor to rotate, and the rotation of the rotating cylinder 20 causes the inclined surface on the riveting disc 21 to rivet the ball seat, thereby realizing the processing of the ball seat.
[0032] The principle of this invention is as follows: When the equipment is started, the circular rotating disk 12 on the base 1 rotates at a constant speed under the drive of the motor, causing the rotating disk 12 to drive the ball seat to rotate. At this time, the inclined copper tube 14 is pushed by the cylinder to approach the rotating ball seat, and lubricating oil is evenly coated onto the inner wall of the ball seat through the channel of the copper tube 14. After the oiling is completed, the transverse slide rail of the bracket 2 is activated, and the bottom cylinder of the pneumatic gripping manipulator 8 is activated, causing the gripper to descend and accurately grasp the ball seat, and then vertically lift it away from the rotating disk 12.
[0033] The robotic arm holding the ball seat moves horizontally along the slide rail to the pre-pressing station and places the ball seat in the positioning slot of the support seat 10. At this time, the operator places the ball head at the pneumatic clamping cylinder 15, and the pneumatic clamping cylinder 15 of the pre-pressing mechanism 4 then rises and falls. The pneumatic clamping cylinder 15 suspended at the top descends along the vertical guide column and then continues to press down until the ball head is fully embedded in the ball seat slot, completing the interference fit assembly. The pre-pressed component is transferred laterally through the displacement seat 9, and the dust cover seat 11 below the support seat 10 moves synchronously to the predetermined position. The dust cover pressing mechanism 5 starts to work: the lifting seat 16 drives the clamping robotic arm to descend and grab the dust cover. After lifting, the displacement seat 9 moves laterally to align the dust cover seat 11 with the assembly position. The clamping robotic arm releases the dust cover to the edge of the ball seat, and the top pressing head 18 then presses down to tightly fasten the dust cover to the outer edge of the ball seat.
[0034] The assembly is transferred again to the final riveting station via the displacement seat 9. The lifting block 19, carrying the rotating mechanism, descends as a whole, and the riveting disc 21 contacts the end face of the ball seat. Driven by a motor, the riveting disc 21 rotates at high speed, and its surface spiral cam structure applies continuous rotational extrusion to the edge of the ball seat, causing the metal material to undergo plastic deformation to form a ring-shaped riveting structure, ultimately completing the permanent fixation of the ball head within the ball seat.
[0035] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
