Description

Technical Field

[0001] This utility model belongs to the technical field of automotive parts assembly equipment, and relates to a device for press-fitting A-arms and ball joints. Background Technology

[0002] In the automotive manufacturing industry, the requirements for the precision and reliability of component assembly are extremely high. The assembly of the A-arm and ball joint is a crucial production step. As a key component for transmitting force and torque, the connection quality between the A-arm and the ball joint directly affects the equipment's handling performance, stability, and service life. Traditionally, the press-fitting process of A-arms and ball joints mostly relies on manual operation or simple tooling equipment. This not only depends on the operator's experience and skill level but also results in low work efficiency, making it difficult to meet the needs of large-scale automated production. During the press-fitting process, due to the instability of manual operation, problems such as uneven pressing force and positional deviation of the ball joint can easily occur, making it difficult to guarantee the precision and consistency of the press-fitting. This can easily lead to problems such as improper ball joint installation and uneven rubber pressure, potentially causing safety hazards. Utility Model Content

[0003] This invention provides an A-arm and ball joint pressing device to solve the problems of low work efficiency, poor pressing accuracy and unstable quality in the existing manual pressing of A-arm and ball joint.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: It includes an A-arm support plate and a base plate. The base plate is provided with a limiting support, an A-arm limiting block, and a hydraulic cylinder support. The A-arm limiting block is located between the limiting support and the hydraulic cylinder support. The limiting support is provided with a ball joint limiting block. The hydraulic cylinder support is provided with a hydraulic cylinder. The piston rod of the hydraulic cylinder is provided with a ball joint pressure head. The A-arm is placed on the A-arm support plate. The ball joint mounting part of the A-arm is placed on the A-arm limiting block, and one side of the ball joint mounting part of the A-arm is in contact with the ball joint limiting block. First, the ball joint is passed through the mounting hole of the ball joint mounting part of the A-arm. The ball joint limiting block limits one end of the ball joint. The hydraulic cylinder is activated to control the extension of the piston rod. The ball joint pressure head pushes the ball joint into the mounting hole of the ball joint mounting part of the A-arm, so that the rubber of the ball joint is in a pressure-holding state in the mounting hole of the ball joint mounting part of the A-arm to complete the press-fitting.

[0005] A more specific technical solution to the above technical solution may be: the bottom of the A-arm support plate is provided with multiple support columns, the lower part of the support columns is provided with a support sleeve, the upper part of the support sleeve is provided with a nut, and the lower part of the support column is threaded and screwed into the nut, so that the height of the A-arm support plate can be adjusted.

[0006] Furthermore: the limiting support is fixedly mounted on the base plate by a bolt assembly, the ball joint limiting block is fixedly mounted on the limiting support by a bolt assembly, the ball joint limiting block has a limiting hole, and the mandrel of the ball joint can be embedded in the limiting hole.

[0007] Furthermore: the A-arm limiting block is fixedly installed on the base plate by a positioning pin, and a limiting baffle is provided on one side of the A-arm limiting block. The limiting baffle is used to position the mounting part of the A-arm ball joint.

[0008] Furthermore: the cylinder support is fixedly mounted on the base plate by bolt assembly, the cylinder body of the hydraulic cylinder is fixedly mounted on the cylinder support by bolt assembly, and the ball joint pressure head is fixedly mounted on the piston rod of the hydraulic cylinder by screws.

[0009] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: By setting a limiting support and an A-arm limiting block on the base plate, the A-arm and ball joint can be accurately positioned and limited, ensuring the accuracy of the ball joint press-fit. The hydraulic cylinder drives the ball joint press head to accurately install the ball joint into the mounting hole of the A-arm ball joint mounting part, and keeps the rubber of the ball joint in a pressure-holding state, ensuring a tight connection between the ball joint and the A-arm, and improving the reliability of the connection between the A-arm and the ball joint. This device has a simple structure and is easy to operate. Through reasonable layout and the mutual cooperation of various components, it realizes automated press-fitting of the A-arm and the ball joint, reducing manual labor intensity and improving press-fitting efficiency.

Multiple support columns 2 are provided at the bottom of the A-arm support plate 1. A support sleeve 12 is located below each support column 2, and a nut 11 is located on the upper part of the support sleeve 12. The lower part of each support column 2 is threaded and screwed into the nut 11, allowing adjustment of the height of the A-arm support plate 1. The base plate 7 is equipped with a limiting support 3, an A-arm limiting block 5, and a cylinder support 8. The A-arm limiting block 5 is located between the limiting support 3 and the cylinder support 8. The limiting support 3 is fixedly installed on the left side of the base plate 7 by a bolt assembly. The A-arm limiting block 5 is fixedly installed on the middle part of the base plate 7 by a positioning pin. The cylinder support 8 is fixedly installed on the right side of the base plate 7 by a bolt assembly. The ball joint limiting block 4 is fixedly installed on the right side of the limiting support 3 by a bolt assembly. The ball joint limiting block 4 has a limiting hole 14. In this example, the shape of the limiting hole 14 corresponds to the spindle of the ball joint. All are square in shape. The square mandrel of the ball joint can be embedded in the square limiting hole 14. A limiting baffle 13 is provided on one side of the A-arm limiting block 5. The limiting baffle 13 is used to position the mounting part of the ball joint of the A-arm 15. The limiting support 3 is provided with a ball joint limiting block 4. The hydraulic cylinder support 8 is provided with a hydraulic cylinder 9. The cylinder body of the hydraulic cylinder 9 is fixedly installed on the hydraulic cylinder support 8 by bolt assembly.

Then, pass the ball joint through the mounting hole of the ball joint mounting part of the A-arm 15, so that the square mandrel of the ball joint is embedded in the square limiting hole 14 of the ball joint limiting block 4. Hang the snap ring 16 on the ball joint pressing head 6, start the hydraulic cylinder 9 to control the piston rod 10 to extend, and push the ball joint into the mounting hole of the ball joint mounting part of the A-arm 15 through the ball joint pressing head 6, so that the rubber of the ball joint is in a pressure-holding state in the mounting hole of the ball joint mounting part of the A-arm 15. Then, use the snap ring 16 clamp to install the snap ring 16 into the mounting hole of the ball joint mounting part of the A-arm 15.
