Technical Field
[0001] This utility model relates to the field of automotive shock absorber technology, specifically to a shock absorber CDC assembly device. Background Technology
[0002] CDC (Continuous Damping Control) is an active suspension system that optimizes vehicle handling and comfort by adjusting the damping force of the shock absorber in real time. In the automotive shock absorber manufacturing process, the component that can adjust the damping of the shock absorber is usually called CDC. The CDC assembly is composed of multiple valve cores and electromagnets and is the heart of the entire adjustable damping shock absorber. As an important component of the automotive continuously adjustable damping shock absorber, the performance of the CDC assembly has a significant impact on the performance of the shock absorber.
[0003] The assembly technology of CDC (Damping Adjustable Shock Absorber) components is complex and requires a high level of expertise, resulting in a low degree of automation. The outer cylinder of the CDC is a cylindrical structure, and the inner side is usually equipped with CDC valve core parts. On the production line, the installation of CDC valve core parts is usually done manually by pressing and assembling. Workers hold the outer cylinder of the CDC in one hand and the CDC valve core part in the other, and install the valve core part by finding the right angle and aligning the position. This method is inefficient and results in poor product consistency. Because the O-ring needs to pass through the hole during the valve core pressing process, it is very easy to cut the O-ring, which will cause the product to be scrapped, and this is not easily noticed by humans.
[0004] Therefore, designing a device to assist in the press-fitting of CDC valve cores and improve installation accuracy and efficiency is the problem that the inventors want to solve. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide an integrated control system for wheeled excavators that enables auxiliary CDC valve core press-fitting, thereby improving installation accuracy and efficiency.
[0006] The technical solution adopted by this invention to solve its technical problem is: a shock absorber CDC assembly device, which includes a support base. A servo telescopic motor is bolted to the lower end face of the support base. The output end of the servo telescopic motor passes through a through hole in the middle of the support base. The output end of the servo telescopic motor is connected to a coupling and a motor extension shaft is connected through the coupling. A flange is bolted to the upper end of the motor extension shaft. A fixing plate is bolted to the flange. A sensor fixing plate is bolted to the upper end face of the fixing plate. A torque sensor is bolted to the upper end of the sensor fixing plate. A tooling fixing base is bolted to the upper end of the torque sensor. Four guide rails are bolted to the four corners of the fixing plate. Each of the four guide rails passes through four light holes in the support base. A linear bearing is fixed to each light hole. The four guide rails pass through the four linear bearings and slide in fit.
[0007] Furthermore, the bottom of the linear bearing is provided with a flange structure, which is connected to the support base by bolts.
[0008] Furthermore, mounting holes are provided at all four corners of the support base.
[0009] Furthermore, when the telescopic motor is retracted to its lowest position, the coupling does not contact the support base.
[0010] Furthermore, the tooling fixture has a groove for mounting CDC valve core parts.
[0011] Furthermore, the support base is connected to the main frame of the CDC assembly unit by bolts.
[0012] Furthermore, when the CDC valve core component is placed in the groove, its axis coincides with the axis of the tooling fixture.
[0013] The beneficial effects of this utility model are: 1. This utility model replaces manual labor with a servo telescopic motor, support base, and fixing plate to lift and install valve core parts. At the same time, a torque sensor is set up to detect pressure in real time, realizing the function of assisting in the press-fitting of CDC valve cores and improving installation accuracy and efficiency.

[0016] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0017] See Figure 1 This is a structural view of the present invention. A shock absorber CDC assembly device includes a support base 3. A servo telescopic motor 1 is bolted to the lower end of the support base 3. The output end of the servo telescopic motor 1 passes through a through hole in the middle of the support base 3. The output end of the servo telescopic motor 1 is connected to a coupling 5 and a motor extension shaft 6 is connected to the coupling 5. A flange is bolted to the upper end of the motor extension shaft 6. A fixing plate 7 is bolted to the flange. A sensor fixing plate 8 is bolted to the upper end of the fixing plate 7. A torque sensor 9 is bolted to the upper end of the sensor fixing plate 8. A tooling fixing seat 10 is bolted to the upper end of the torque sensor 9. Four guide rails 2 are bolted to the four corners of the fixing plate 7. Each of the four guide rails 2 passes through a light hole in the support base 3. A linear bearing 4 is fixed to each light hole. The four guide rails 2 pass through the four linear bearings 4 and slide together.
[0018] The bottom of the linear bearing 4 is provided with a flange structure, which is connected to the support base 3 by bolts.
[0019] Mounting holes are provided at all four corners of the support base 3. The support base 3 is connected to the main frame of the CDC assembly device through bolts and mounting holes. The CDC assembly device includes the CDC assembly device of this utility model for press-fitting the valve core, the device for rotating and installing the nuts at both ends of the CDC outer cylinder, and the rotary manipulator used in conjunction with this utility model.
[0020] The CDC assembly unit is equipped with a controller, which oversees all electronic components and coordinates the actions of various mechanisms. The servo telescopic motor 1 is connected to the controller via wires.
[0021] When the telescopic motor is retracted to its lowest position, the coupling 5 and the support base 3 are not in contact.
[0022] The tooling fixture 10 has a groove for installing the CDC valve core part 11. When the CDC valve core part 11 is placed in the groove, its axis coincides with the axis of the tooling fixture 10.
[0023] When the CDC valve core part 11 is installed on the tooling fixture 10, the controller controls the servo telescopic motor 1 to extend upward, driving the fixing plate 7 to move upward along the linear bearing 4 to press the CDC valve core part 11. During the upward process, the CDC valve core part 11 will be gradually pressed into the inner side of the CDC outer cylinder that has been held and suspended above by the rotating manipulator.
[0024] The torque sensor 9 can transmit the pressure on the CDC valve core part 11 during the press-fitting process to the controller in real time, ensuring that the O-ring on the CDC valve core part 11 is not cut and the press-fitting torque is qualified. When the host system detects that the CDC valve core part 11 has been pressed into the predetermined position, the output end of the servo telescopic motor 1 retracts and returns to the origin.
[0025] This utility model uses a servo telescopic motor 1, a support base 3, and a fixing plate 7 to replace manual labor, lifting the parts for valve core installation. At the same time, a torque sensor 9 is set up to detect the pressure in real time, realizing the function of assisting in the press-fitting of CDC valve cores and improving installation accuracy and efficiency.
