Description

Technical Field

[0001] The utility model relates to the field of shock absorber tooling, in particular to an alignment tooling for an external CDC shock absorber assembly. Background Art

[0002] With the continuous development of automotive technology, vehicle comfort and handling have become the focus of consumers. As an important technology, CDC shock absorbers achieve optimal vehicle performance under different road conditions by adjusting the damping force in real time.

[0003] Typically, a shock absorption system is primarily composed of a shock absorbing spring and a shock absorber, which work together to provide shock absorption for the vehicle. When a vehicle is traveling on an uneven road, the spring is deformed (compressed or stretched) by the impact of the ground. As the spring returns to its original shape, it vibrates back and forth, and the shock absorber dampens the spring, suppressing its back-and-forth swinging. The CDC shock absorber, based on the traditional hydraulic shock absorber structure, has two inner and outer chambers, through which oil can flow. The CDC control valve uses an electronically controlled valve to change the cross-sectional area of ​​the connecting portion between the two chambers, thereby changing the shock absorber damping. This allows for real-time adjustment of the damping force, achieving optimal vehicle performance under varying road conditions.

[0004] However, the precise installation requirements of the CDC shock absorber assembly pose a challenge to the assembly process. The shock absorber spring, CDC control valve, and shock absorber must be aligned and assembled. In a vehicle suspension system, correct shock absorber installation is crucial for vehicle handling and ride comfort. Incorrect shock absorber assembly installation can degrade suspension system performance and even directly damage the shock absorber or other components. Therefore, it is necessary to design an efficient and convenient alignment tool for the external CDC shock absorber assembly. Summary of the Invention

[0022] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0023] Example

[0024] like Figure 1 、 2 The alignment tooling of the external CDC shock absorber assembly shown in the figure is composed of an alignment base 1, a top alignment device, and a bottom platform 7. Based on the structural characteristics of the external CDC shock absorber, the bracket and the top alignment guide are used to ensure that the shock absorber and other components of the suspension system, such as the spring 101, the iron part 102, the solenoid valve 103, the guide arm, the bearing, etc. (see Figure 2 ), correctly aligned and installed. It is simple and convenient, improving operator efficiency and reducing the chance of error.

[0025] In this embodiment, a movable base 7 is provided, on which the alignment base 1 and the top alignment device are mounted. The bottom of the base 7 is supported by an aluminum square tube bracket and is equipped with universal wheels, which provides high flexibility and greatly improves the efficiency of on-site workers in storage, retrieval and movement operations.

[0026] Alignment base 1, mounted on the top of base platform 7, secures the shock absorber cylinder. Adjustable brackets are installed on the sides of alignment base 1 for aligning the CDC solenoid valve in the external CDC shock absorber assembly. Alignment base 1 is constructed of a nylon base plate, ensuring vertical fixation of the shock absorber cylinder. Its low hardness effectively prevents wear on the metal and paint surfaces during assembly, ensuring the product's appearance and quality.

[0027] The adjustable bracket includes an alignment support plate 2 and an alignment bracket 3. The alignment bracket 3 and the alignment support plate 2 are connected to each other in a lifting manner by a slide rail connection, and a locking mechanism is provided between the alignment bracket 3 and the alignment support plate 2.

[0028] In this embodiment, the locking mechanism includes a strip-shaped locking groove 31 and a locking screw 32 provided on the alignment bracket 3 . The screw passes through the strip-shaped locking groove 31 and is locked on the alignment bracket 3 .

[0029] The center of the bottom side of the alignment bracket 3 has a downward-opening track groove 33. The outer side of the alignment support plate 2 is provided with a track protrusion 21 that fits into the track groove 32. The track groove 33 and the track protrusion 21 engage, allowing the alignment support plate 2 to be raised and lowered along the track line. The top of the alignment support plate 2 has a notch 34 that supports the CDC solenoid valve 103, providing stable support for the CDC solenoid valve and facilitating precise alignment and installation. This notch 34 is a V-shaped groove.

[0030] In this embodiment, there is a pair of adjustable brackets, which are symmetrically arranged on both sides of the alignment base 1.

[0031] It ensures the precise positioning of the shock absorber solenoid valve and the iron parts at a specific angle, further improving the positioning accuracy and operating efficiency of the entire system.

[0032] The top alignment device includes an alignment top plate 4, which corresponds to the upper part of the alignment base 1. When the shock absorber assembly is placed on the upper part of the alignment base 1, the spring assembly on the upper part of the shock absorber assembly is aligned with the alignment top plate 4. When the alignment top plate 4 is pressed down, the downward pressure acts on the spring assembly, which provides a fixing and limiting function for the installation between the spring assembly and the shock absorber, thereby facilitating assembly.

[0033] In this embodiment, the top plate 4 is raised and lowered by a lifting guide, allowing it to press down on the spring assembly of the shock absorber. Using a press-type positioning technology, it precisely captures the specific circular hole of the upper iron piece of the shock absorber to achieve stable positioning.

[0034] In this embodiment, the lifting guide device is composed of a guide frame and a lifting seat 51. The guide frame is a frame structure composed of a pair of guide columns 6 vertically erected on the surface of the base 7 and a top plate 61 connecting the two guide columns 6. The lifting seat 51 is used to connect to the alignment top plate 4, and is slidably sleeved on the guide columns 6. The upper part is provided with a tension spring 52 support connected to the top plate 61 to provide lifting force. It should be noted that this embodiment provides a tooling for the alignment of the shock absorber, and its downward pressure is provided by other external hydraulic presses / devices. Among them, the lifting guide device ensures the precise alignment of the axis of the lifting seat 51, the alignment top plate 4 and the alignment base 1, effectively reducing the misjudgment rate during the alignment of the solenoid valve and improving the accuracy and reliability of the overall operation.

[0035] In this embodiment, a plurality of connecting columns 53 are provided between the lifting seat 51 and the alignment top plate 4. The connecting columns 53 are evenly arranged around the lifting seat 51, so that the lifting seat 51 and the alignment top plate 4 have a flange-shaped structure, and the force is more evenly distributed. The lifting seat 51 is connected to the guide column 6 by a linear bearing 54, and the lifting resistance is small. The linear bearing 54 is a square flange linear bearing 54. The introduction of the square flange linear bearing 54 significantly reduces the friction during the positioning process, which not only improves the accuracy of the tooling alignment, but also enhances the stability of the system. After the operation is completed, the tension spring 52 pillars work together to quickly return the lifting seat 51 and the alignment top plate 4 to ensure the continuity and convenience of the operation.

[0036] The alignment tooling of the external CDC shock absorber assembly of the utility model optimizes the assembly process of the shock absorber, improves the accuracy and efficiency of the operation, and effectively protects the product surface and reduces potential risks in the production process through careful component selection and design.

[0037] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
